LETTER FROM THE CHAIRMAN
2022 was a record year for Tenaris. We were able to take advantage of favorable market conditions, particularly in
North America, and the efficient deployment of our global industrial system to generate strong increases in sales and
margins through the year.
Our sales grew 80% to USD 11.8 billion, our EBITDA rose to USD 3.6 billion, and our net income rose to USD 2.5 billion,
or 22% of net sales. With a solid balance sheet and good prospects for an increase in cash flow in the year ahead, we
are proposing to raise our dividend for the 2022 year by 24% to USD 0.51 per share.
We produced over 3.5 million tons of steel pipes worldwide, sustaining an ongoing ramp up of our facilities in the USA
and high levels of production throughout our industrial system. Despite the use of longer and more complex production
and logistics routes, we were able to maintain high standards for safety, product quality and consumption of materials.
During the year, we hired 6,500 new employees and, in our induction training routines, we paid close attention to the
importance of having a safety mindset with awareness and behaviors suitable for the industrial environment of our
shop floor. We empower all our employees to be proactive in always taking preventive safety actions. Our lost time
injury frequency rate for the year declined by 10% to 0.9 per million man hours worked. We are grateful to our people
working in the plant for their contribution to this result.
We increased the deployment of our Rig Direct® services. We are now serving over 500 rigs directly worldwide. Our
unique service platform allows us to integrate our operations more closely with our customers, minimizing material
production and flows, and provide digital and technical services that can further differentiate us from our competitors.
As we increased production, sales and service, our logistics operations have reached a substantial magnitude. To give
an idea of the efforts involved, between inter-mill transportation and delivery to customers, we moved around 10
million tons of material all around the world. We are strengthening the reliability of our supply chain through the
digitalization of our material flows.
2022 marked a turning point in our deployment in the United States. The country accounted for more than 40% of our
total sales, most of which are now produced locally. We brought the Bay City mill to full production capacity and
ramped up production in the rest of our US industrial system including the restart of production of welded pipes and of
heat treatment and finishing at our Baytown and Koppel sites. We hired more than 1,500 new employees during the
year and now employ 3,600 persons in the country.
The energy transition is progressing, but its pace will be gradual. The phasing out of fossil fuels needs to be balanced
with considerations of energy security, access and affordability in a world which has distinct regional priorities. Our role
is to support our customers with high quality, efficient tubular solutions so that current sources of energy can be
delivered securely and affordably with the lowest impact possible on the environment. At the same time, we are
developing products and solutions for cleaner sources of energy and carbon abatement systems, such as hydrogen,
geothermal energy and carbon dioxide transportation and storage systems.
An essential part of our role is to reduce the carbon emissions from our operations as quickly as technology and market
conditions allow. We are making good progress towards our initial target of reducing the carbon emissions intensity of
our operations by 30% by 2030 compared to a 2018 baseline. Around 30% of our capex is now being directed to
projects that will contribute to this target and other environmental objectives. In addition to our wind farm in
Argentina, we will be making investments which will contribute to improving energy efficiency in Italy and Argentina
and improving air quality at our Koppel steel shop in the United States.
As we look ahead, we view that the current balance in the oil market and high demand for LNG will support oil and gas
prices and investment in the sector. We expect that the number of oil and gas wells drilled around the world in 2023
will increase and this will drive global OCTG demand to around 16 million tons to reach its highest level since 2014.
With the increase in activity, we expect further sales and cash flow growth with increases in sales to offshore
developments, in the Middle East and in pipeline infrastructure in South America.
Our achievements over the past year that will support this growth include: our multi-year agreement with ExxonMobil
to supply their offshore operations in Guyana; our agreements with Petrobras to supply their pre-salt operations; the
renewal of our long-term worldwide agreement with ENI; the renewal of our long-term agreement with QatarGas and
the consolidation of our long-term agreement with ADNOC. We also extended our long-term agreements with YPF and

Pemex and were awarded supply agreements for major gas pipeline projects for the Vaca Muerta field in Argentina and
the North Field expansion in Qatar.
The sustainability of our operations worldwide depends on the support and development of our local communities.
Safety and care for the environment are paramount, as is support for employee and community development. Given its
essential role in progress and development, we have put education at the core of our community activities.
Our efforts to strengthen technical education are increasingly recognized. The Roberto Rocca Technical School in
Campana became the first school in Argentina to be qualified as a Technical Training Center providing certifications to
members of the local community for Industry 4.0 -related technical training, in partnership with German automation
and industrial companies, FESTO and Siemens.
In Cartagena, Colombia, through our Roberto Rocca Technical Gene program, we helped to redesign a technical school,
introducing new technical study courses in partnership with the SENA national learning system and improving job
opportunities with local industrial companies for young people in the community.
Over the past year, Tenaris has made good progress on many fronts and produced record financial results. We have
been able to achieve this only thanks to the confidence our customers have placed in us and the constant efforts and
outstanding performance of our diverse and united team of employees around the world in a volatile and fast-moving
environment. We thank them together with our suppliers and shareholders for their continued support for our
company.
Sincerely,
Paolo Rocca

CONSOLIDATED MANAGEMENT REPORT
Key Information
Risk Factors
You should carefully consider the risks and uncertainties described below, together with all other information contained
in this annual report, before making any investment decision. Any of these risks and uncertainties could have a material
adverse effect on our business, revenues, financial condition and results of operations, which could in turn affect the
price of shares and ADSs.
Risks Relating to Our Business and Industry
Sales and profitability may fall as a result of downturns in the international price of oil and gas and other factors and
circumstances affecting the oil and gas industry
We are a global steel pipe manufacturer with a strong focus on manufacturing products and providing related services
for the oil and gas industry. The oil and gas industry is a major consumer of steel pipe products worldwide, particularly
for products manufactured under high quality standards and demanding specifications. Demand for steel pipe products
from the oil and gas industry has historically been volatile and depends primarily upon the number of oil and natural
gas wells being drilled, completed and reworked, and the depth and drilling conditions of these wells. The level of
exploration, development and production activities of, and the corresponding capital spending by, oil and gas
companies, including national oil companies, depends primarily on current and expected future prices of oil and natural
gas and is sensitive to the industry’s view of future economic growth and the resulting impact on demand for oil and
natural gas. Several factors, such as the supply and demand for oil and gas, the development and availability of new
drilling technology, political and global economic conditions, and government regulations, affect these prices. For
example, drilling technology has allowed producers in the United States and Canada to increase production from their
reserves of tight oil and shale gas in response to changes in market conditions more rapidly than in the past. In
addition, government initiatives to reduce GHG emissions, such as the introduction of a carbon tax or carbon-pricing
systems (such as the EU Carbon Border Adjustment Mechanism), the adoption of “cap-and-trade” systems (such as the
EU Emissions Trading System (“ETS”)) or other measures to promote the use of renewable energy sources or, electric
vehicles, could also affect oil and gas prices. When the price of oil and gas falls, oil and gas companies generally reduce
spending on production and exploration activities and, accordingly, make fewer purchases of steel pipe products. Major
oil-and gas-producing nations and companies have frequently collaborated to balance the supply (and thus the price) of
oil in the international markets. A major vehicle for this collaboration has been the Organization of Petroleum Exporting
Countries (“OPEC”) and many of our customers are state-owned companies in member countries of OPEC, which plays
a significant role in trying to counter falling prices, as was the case in 2020, when the industry was hit by the effects of
the COVID-19 pandemic. For more information on risks relating to climate change regulations, see “Risks Relating to
Our Business and Industry - Climate change legislation and increasing regulatory requirements aimed at transitioning to
a lower-carbon economy may reduce demand for our products and services and result in unexpected capital
expenditures and costs, and negatively affect our reputation”.
Climate change legislation and increasing regulatory requirements aimed at transitioning to a lower-carbon
economy may reduce demand for our products and services and result in unexpected capital expenditures and costs,
and negatively affect our reputation
There is an increased attention on GHG emissions and climate change from different sectors of society. The Paris
Agreement, adopted at the 2015 United Nations Climate Conference, sets out the global framework to limit the rising
temperature of the planet and to strengthen the countries’ ability to deal with the effects of climate change. The EU
ETS signaled a major EU energy policy to combat global warming based on a “cap & trade” program, and the European
Green Deal, launched in 2019, focuses on adopting the required policies and measures aimed at reaching zero GHG
emissions in Europe by 2050. The EU taxonomy classification system, which establishes a list of environmentally
sustainable economic activities, is designed to help the EU scale up sustainable investment and implement the
European Green Deal. Similarly, the U.S. Inflation Reduction Act of 2022 calls for a reduction of carbon emissions by
roughly 40% by 2030. Other countries are introducing or considering similar measures or regulations which would
lower emissions. If there is no meaningful progress in lowering emissions in the years ahead, there is an increased
likelihood of abrupt policy interventions as governments attempt to meet their environmental goals by adopting policy,
legal, technology and market changes in the transition to a low-carbon global economy. We provide products and
services to the oil and gas industry, which accounts, directly and indirectly, for a significant portion of GHG emissions.

Graphics
Annual Report 2022

Existing and future legislation and regulations related to GHG emissions (such as increased pricing of GHG emissions
and enhanced emissions-reporting obligations) and climate change, as well as government initiatives to promote the
use of alternative energy sources and substitute existing products and services with lower emissions options (with
many jurisdictions implementing tax advantages and other subsidies to promote the development of renewable energy
sources, or even requiring minimum thresholds for power generation from renewable sources) may significantly curtail
demand for and production of fossil fuels, such as oil and natural gas. These initiatives, together with the growing social
awareness regarding climate change and other environmental matters, have resulted in increased investor and
consumer demand for renewable energy and additional compliance requirements for fossil energy projects, which are
likely to become more stringent over time and to result in substantial increases in costs for the oil and natural gas
industry, potentially leading to write-offs and early retirement of existing assets. Furthermore, ongoing technological
developments in the renewable energy industry are making renewable energy increasingly competitive with fossil-fuels.
If this trend continues, energy demand could shift increasingly towards more environmentally sustainable sources such
as hydroelectrical, solar, wind and other renewable energies, which would, in turn, reduce demand for oil and natural
gas, thus negatively affecting demand for our products and services and, ultimately, our future results of operations. In
addition, adoption of new climate change legislation in the countries in which Tenaris operates could result in
incremental operating costs (such as incremental compliance costs and increased insurance premiums) and unexpected
capital expenditures and, eventually, affect our competitiveness and reduce our market share. Also, shifts in customer
preferences and failure to respond to shareholders’ demand for climate-related measures and environmental standards
could harm our reputation, adversely affect the ability or willingness of our customers or suppliers to do business with
us, negatively impact workforce management and planning, erode stakeholder support and restrict or reduce access to
financial resources. For more information on Tenaris’s climate change initiatives, please see “Operating and Financial
Review and Prospects Overview Climate Change”.
The physical risks resulting from climate change, including extreme weather conditions and shifts in weather
patterns, have in the past and may in the future adversely affect our operations and financial results
Our business has been, and in the future could be, affected by severe weather in areas where we operate, which could
materially affect our operations and financial results. Extreme weather conditions and natural disasters such as
hurricanes, flooding or coastal storm surges have in the past resulted in, and may in the future result in, the shutdown
of our facilities, evacuation of our employees or activity disruptions at our clients well-sites or in our supply chain. For
example, the severe freeze in the United States and Mexico in early 2021, caused gas and power shortages in Texas,
resulting in additional costs and production disruptions and losses. Additionally, chronic climate changes, such as
changes in precipitation patterns and rising of average temperatures and sea levels may result in increased operating or
capital costs due to supply shortages or damage to facilities, increased insurance premiums or reduced availability of
insurance, decreases in revenue derived from lower sales, lower production capacity or negative impacts on workforce
and write-offs and/or early retirement of assets, all of which could adversely affect our financial condition, results of
operations and cash flows. For more information on Tenariss climate change initiatives, please see “Operating and
Financial Review and Prospects Overview Climate Change”.
Competition in the global market for steel pipe products may cause us to lose market share and hurt our sales and
profitability
The global market for steel pipe products is highly competitive, with the primary competitive factors being price,
quality, service and technology. In recent years, substantial investments have been made, especially in China but also in
the United States and the Middle East, to increase production capacity of seamless steel pipe products, and as a result
there is significant excess production capacity, particularly for “commodity” or standard product grades. Production
capacity of more specialized product grades has also increased. At the same time, the high cost and long lead times
required to develop the most complex projects, particularly deepwater projects, has led to a slowdown in new
developments in a context of low and more volatile oil prices. Despite our efforts to develop products and services that
differentiate us from our competitors, reduced demand for steel pipe products from these complex projects means that
the competitive environment is expected to remain intense in the coming years and our effective competitive
differentiation will be a key success factor. In addition, there is a risk of unfairly traded steel pipe imports in markets in
which Tenaris produces and sells its products, and we can give no assurance with respect to the application of
antidumping duties and tariffs or the effectiveness of any such measures.
Our sales may be affected as a result of antidumping and countervailing duty proceedings or by the imposition of
other import restrictions or local content requirements
Because of the global nature of our operations, we export and import products from several countries and, in many
jurisdictions, we supplement domestic production with imported products. We import OCTG from Argentina and

Graphics

11
Mexico to complement our significant and growing production in the United States. From time to time, local producers
seek the imposition of import restrictions or the initiation of antidumping or countervailing duty proceedings. For
example, in October 2021, the U.S. Department of Commerce (“DOC”) initiated antidumping duty investigations of
OCTG imports from Argentina, Mexico, and Russia and countervailing duty investigations of OCTG imports from Russia
and South Korea, which resulted in a determination by the International Trade Commission (“ITC”), issued in October
2022, that the imports under investigation caused injury to the U.S. OCTG industry, bringing the investigation phase to
a conclusion. Although Tenaris and other parties have appealed the agencies’ determinations from the investigation to
the Court of International Trade, Tenaris is required to pay antidumping duty deposits until such time the imports are
reviewed by the DOC to determine whether final duties are necessary for the specific period under review. For more
information on this matter, please refer to “Consolidated Statements and Other Financial Information Legal
Proceedings”. Additionally, in June 2021, Canada initiated an antidumping investigation on OCTG from Mexico; in 2022,
the Canadian International Trade Tribunal found that Mexican imports were not injuring the Canadian OCTG industry
and closed the inquiry without imposing any duties. Antidumping or countervailing duty proceedings, any resulting
penalties or any other form of import restriction have in the past impeded, and may in the future restrict, our access to
important export markets for our products, thereby adversely impacting our sales or limiting our opportunities for
growth.
In addition, several jurisdictions have begun to impose or expand local content requirements. For example, in recent
years Saudi Arabia has implemented various measures aimed at increasing local content particularly from suppliers to
state-owned companies such as Saudi Arabian Oil Company (“Saudi Aramco”) and we can expect that measures
favoring the development of local production will increase as Saudi Arabia seeks to create employment opportunities
for its citizens and diversify its economy away from its dependence on oil and gas production. Other countries, such as
Brazil, Ecuador, Indonesia, Nigeria and the United Arab Emirates, have also put in place significant local content
requirements. If countries impose or expand local content requirements or put in place regulations limiting our ability
to import certain products, our competitive position could be negatively affected. Therefore, if any of these risks
materialize, we may not continue to compete effectively against existing or potential producers and preserve our
current shares of geographic or product markets, and increased competition may have a material impact on the pricing
of our products and services, which could in turn adversely affect our revenues, profitability and financial condition.
Our sales may also be affected as a result of other international trade regulations
The shipment of goods and services across international borders subjects us to extensive trade laws and regulations.
Our import and export activities are governed by customs laws and regulations in each of the countries where we
operate. Moreover, the European Union, the United States and other countries control the import and export of certain
goods and services and impose related import and export recordkeeping and reporting obligations. Those governments
have also imposed economic sanctions against certain countries, persons and other entities, such as sanctions that
restrict or prohibit transactions involving Iran, Syria, Venezuela and Russia or their citizens or companies. For more
information on the impact on our business of the sanctions on Russia as a result of the armed conflict in Ukraine, see
“Risks Relating to Our Business and Industry - The Russia-Ukraine armed conflict may adversely affect our operations”.
Similarly, we are subject to the U.S. anti-boycott laws. Trade laws and regulations are complex and frequently changing,
and they may be enacted, amended, enforced or interpreted in a manner that could materially impact our operations.
For example, in March 2018, under Section 232 of the Trade Expansion Act of 1962 (“Section 232”), the United States
imposed a 25% tariff on steel articles imported from all countries, with the exemption of Canada and Mexico, as
member states of the USMCA, and imports of steel tubes from Australia, Argentina, Brazil and South Korea (the latter
three with specific quotas per product). The U.S. government has also granted five successive exemptions on imports
from Italy, Mexico, Romania and Argentina, of steel billets to be used at our Bay City mill, for an aggregate amount of
1,750,000 tons. Exemptions are granted only for a one-year term and future requests might not be granted, thus
adversely affecting our operations or revenues. On October 31, 2021, the United States and the EU reached an
agreement whereby Section 232 tariffs were replaced with tariff-rate quotas for steel melted and poured in Europe
starting on January 1, 2022, and steel products imported from the EU for a period of two calendar years (i.e., until 31
December 2023) without the need to reapply. This agreement allows Tenaris to import, through December 31, 2023, up
to 299,376 tons of billets from Italy and Romania without paying the 25% annual tariff. Failure to comply with
applicable trade regulations could also result in criminal and civil penalties and sanctions.

Increases in the cost of raw materials, energy and other costs, limitations or disruptions to the supply of raw
materials and energy, and price mismatches between raw materials and our products may hurt our profitability
The manufacture of seamless steel pipe products requires substantial amounts of steelmaking raw materials and
energy; welded steel pipe products, in turn, are processed from steel coils and plates. The availability and pricing of a
significant portion of the raw materials and energy we require are subject to supply and demand conditions, which can
be volatile, and to tariffs and other government regulations, which can affect continuity of supply and prices. In
addition, disruptions, restrictions or limited availability of energy resources in markets where we have significant
operations could lead to higher costs of production and eventually to production cutbacks at our facilities in such
markets. For example, in early 2021 we suffered gas and power shortages in Texas caused by a severe freeze affecting
the United States and Mexico, which resulted in additional costs and production losses. At any given time, we may be
unable to obtain an adequate supply of critical raw materials with price and other terms acceptable to us. The
availability and prices of raw materials may also be negatively affected by new laws and regulations, including import
controls, sanctions and other trade restrictions, allocation by suppliers, interruptions in production, accidents or natural
disasters, armed conflicts, chronic climate change, changes in exchange rates, worldwide price fluctuations, and the
availability and cost of transportation. For further information related to the impact on our business of the armed
conflict in Ukraine see “Risks Relating to Our Business and Industry - The Russia-Ukraine armed conflict may adversely
affect our operations”. Raw material prices could also be affected by the introduction of carbon prices or taxes, or as a
result of changes in production processes, such as an increased use of metal scrap, adopted by steelmaking companies
seeking to reduce carbon emissions. In addition, we may not be able to recover, partially or fully, increased costs of raw
materials and energy through increased selling prices for our products, or it may take an extended period of time to do
so, and limited availability could force us to curtail production, which could adversely affect our sales and profitability.
Our results of operations and financial condition could be adversely affected by low levels of capacity utilization or
failure to retain qualified workforce
Like other manufacturers of steel-related products, we have fixed and semi-fixed costs (e.g., labor and other operating
and maintenance costs) that cannot adjust rapidly to fluctuations in product demand for several reasons, including
operational constraints and regulatory restrictions. If demand for our products falls significantly, or if we are unable to
operate due to, for example, governmental measures or unavailability of workforce, these costs may adversely affect
our profitability and financial condition. For example, in response to the abrupt and steep downturn of the oil and gas
industry resulting from the oil crisis and the COVID-19 pandemic in 2020, we were required to implement cost-
containment measures and liquidity preservation initiatives, including reduction of our operating activities in several
jurisdictions, temporary closure of facilities in the United States and review of our capital expenditure plans. Temporary
suspensions of operations or closure of facilities generally lead to layoffs of employees, as was our case during the oil
crisis and the COVID-19 pandemic, which may in turn give rise to labor conflicts and impact operations. Cost
containment measures may also affect profitability and result in charges for asset impairments. In addition, in times of
economic growth and high demand for our products we may not be able to retain qualified workforce or hire additional
employees soon enough. Moreover, certain consequences of climate change, such as shifts in customer preferences,
stigmatization of our industry or failure to respond to shareholder demands for climate-related measures could
negatively impact workforce management and planning, adversely affecting employee attraction and retention. For
example, during the post-pandemic recovery period, when we brought production at our Bay City mill to full capacity,
we faced some difficulties in hiring qualified workforce. For more information, see “History and Development of the
Company Sales and Marketing”.
Adverse economic or political conditions in the countries where we operate or sell our products and services may
decrease our sales or disrupt our manufacturing operations, thereby adversely affecting our revenues, profitability
and financial condition
We have significant operations in various countries, including Argentina, Brazil, Canada, China, Colombia, Indonesia,
Italy, Mexico, Nigeria, Romania, Saudi Arabia and the United States, and we sell our products and services throughout
the world. Therefore, like other companies with worldwide operations, our business and operations have been, and
could in the future be, affected from time to time to varying degrees by political, economic, social and public health
developments and changes in laws and regulations. These developments and changes may include, among others,
nationalization, expropriation or forced divestiture of assets; restrictions on production, imports and exports;
antidumping or countervailing duties; travel, transportation or trade bans; interruptions in the supply of essential
energy inputs; currency exchange and/or transfer restrictions, inability or increasing difficulties to repatriate income or
capital or to make contract payments; inflation; devaluation; war or other armed conflicts (including the Russia-
Ukraine armed conflict and regional conflicts in the Middle East and Africa); civil unrest and local security concerns,
including high incidences of crime and violence involving drug trafficking organizations that threaten the safe operation

of our facilities and operations; direct and indirect price controls; tax increases and changes (including retroactive) in
the interpretation, application or enforcement of tax laws and other claims or challenges; cancellation of contract or
property rights; and delays or denials of governmental approvals. Both the likelihood of such occurrences and their
overall impact upon us vary greatly from country to country and are not predictable. Realization of these risks could
have an adverse impact on the results of operations and financial condition of our subsidiaries located in the affected
country and, depending on their materiality, on the results of operations and financial condition of Tenaris as a whole.
For example, in March 2022, we recorded an impairment in the amount of approximately $14.9 million, fully impairing
our investment in a joint venture in Russia that we had established with PAO Severstal (“Severstal”) as a result of the
designation of Severstal’s controlling shareholder as a person subject to EU and UK sanctions. For more information on the
impact on our business of the armed conflict in Ukraine, see “Risks Relating to our Business and Industry The Russia-Ukraine
armed conflict may adversely affect our operations”.
More specifically, Argentina and Mexico are countries in which we have significant operations and relevant risks.
Our business and operations in Argentina may be materially and adversely affected by economic, political, social, fiscal
and regulatory developments, including the following:
Macroeconomic and political conditions in Argentina may adversely affect our business and operations.
Increased state intervention in the stagnant economy, along with the introduction of changes to government
policies, including measures aimed at ensuring the sustainability of sovereign debt (including debt with the
International Monetary Fund and other international creditors); high and unpredictable inflation rates and a
high fiscal deficit in a highly indebted economy, coupled with other government measures affecting investors
confidence, could cause a drop in demand for our products in the domestic market, adversely affecting our
operations and financial results. Similarly, they could also negatively impact the business and operations of our
customers (oil and gas companies operating in Argentina) and consequently our revenues and profitability.
Our business and operations in Argentina may be adversely affected by high inflation rates or by the measures
that may be adopted by the government to address inflation. In particular, increases in services and labor costs
could affect cost-competitiveness and margins, negatively impacting our results of operations. An economic
environment highly characterized by inflation could undermine Argentina’s foreign competitiveness in
international markets and negatively affect economic activity and employment levels. Argentine inflation rate
volatility makes it impossible to estimate with reasonable certainty the extent to which our activity levels and
results of operations could be affected in the future. In addition, an increased level of labor demands in
response to spiraling inflation could trigger higher levels of labor conflicts, and eventually result in strikes or
work stoppages. Any such disruption of operations could have an adverse effect on our operations and
financial results.
Other events that may have an adverse effect on our operations and financial results include increased taxes,
currency devaluation, exchange controls, restrictions on capital flows and export and import taxes or
restrictions. The Argentine Central Bank has tightened its control on transactions that would represent capital
inflows or outflows, forcing Argentine companies to repatriate export proceeds and limiting their ability to
transfer funds outside of Argentina. Argentine companies are required to repatriate export proceeds from
sales of goods and services (including U.S. dollars obtained through advance payment and pre-financing
facilities) and convert such proceeds into Argentine pesos at the official exchange rate. In turn, Argentine
companies must obtain prior Central Bank authorization, which is rarely (if ever) granted, to access the foreign
exchange market to pay for imports of services from related parties or to make dividend or royalty payments.
The Argentine government limits the import of goods and services by controlling access to the foreign
exchange market. In accordance with the current goods and services import control system, in place since
November 1, 2022, the Argentine authorities may, or may not, clear certain import payments and determine
the payment terms. If control systems are maintained or are further tightened, our operations could be
adversely affected. As the context of volatility and uncertainty remains in place as of the date of this annual
report, additional regulations or restrictions that could be imposed by the Argentine government could further
restrict our ability to access the official foreign exchange market, and expose us to the risk of losses arising
from fluctuations in the ARS/USD exchange rate, or cause disruptions to our operations due to lack of
imported raw materials and other inputs, or affect our ability to finance and even carry out major investments
in Argentina, or impair our ability to convert and transfer outside the country funds generated by Argentine
subsidiaries to pay dividends or royalties or make other offshore payments. For additional information on
current Argentine exchange controls and restrictions see “Additional Information Exchange Controls
Argentina” and note 28 “Foreign exchange control measures in Argentina” of our audited consolidated
financial statements included in this annual report.

In recent years, our operations in Argentina experienced constraints in their electricity and natural gas supply
requirements on many occasions. Shortages of energy and natural gas in Argentina have led in the past (and
could lead in the future) to production cutbacks negatively affecting our revenues and profitability; we could
also face increased costs when using alternative sources of energy.
In Mexico, our business could be materially and adversely affected by economic, political, social, fiscal and regulatory
developments, including the following:
The Mexican government exercises significant influence over the Mexican economy and, therefore,
governmental actions concerning the economy and state-owned enterprises could have a significant impact on
Mexico’s private sector and on our Mexican-related operations.
We have a significant credit exposure to Petróleos Mexicanos S.A. de C.V. (“Pemex”), a Mexican state-owned
entity and our main customer in Mexico. Starting in 2019 and through 2020, we built a hefty balance of
accounts receivable with Pemex and we opted to sell some of our Pemex receivables with a discount; our
exposure to Pemex remained high during 2022 and early 2023. Pemex, nevertheless, continues to maintain a
regular payment flow and enabling alternative payment methods, including factoring structures. If we are not
able to reduce our exposure to Pemex and Pemex defaults on its payments, our revenues and profitability
would be adversely affected.
Our Mexican operations could also be affected by criminal violence, primarily due to the activities of drug
cartels and related organized crime that Mexico has experienced and may continue to experience. The city of
Veracruz, where our facility is located, has experienced several incidents of violence. Although the Mexican
government has implemented various security measures and has strengthened its military and police forces,
drug-related crime continues to exist in Mexico. Our business may be materially and adversely affected by
these activities, their possible escalation and the violence associated with them.
In the last few years, the Mexican government made various attempts to modify rules and regulations
governing the energy market in Mexico with potential impact on energy supply and its cost. In March 2021, the
Mexican Congress approved a significant reform to the energy market in Mexico. Among other changes, the
new Energy Industry Law (“LIE”) grants priority to Mexico’s state-owned electric power generation and
distribution company (“CFE”) over private generation competitors in the supply of electric power to the
Mexican market and mandates a revision of power generation and transaction agreements between CFE and
independent electric power suppliers. In addition, the LIE eliminates mandatory power supply auctions for
energy supplies requiring the use of CFE’s distribution network, relaxes the requirements for the granting of
clean energy certificates in favor of CFE, and imposes serious restrictions on the renewable energy generation
system through self-supply, widely used by private companies. The constitutionality of the new LIE was
challenged in court, but on April 7, 2022, the Mexican Supreme Court of Justice rejected the request in a very
tight decision. After the Supreme Court's decision, several participants continued seeking injunctive reliefs
against the LIE on a case-by-case basis. In addition, in September 2021, President Andrés Manuel López
Obrador submitted to Congress a constitutional reform proposal of the electricity sector, which seeks to
reverse the legal framework derived from the 2013 constitutional energy reform that opened the sector to
private investment. On April 18, 2022, the Mexican Congress rejected the constitutional reform proposal of the
electricity sector, as the ruling party failed to obtain the required two-third affirmative vote. More recently, on
June 14, 2022, the Mexican Secretary of Energy (SENER) instructed two decentralized bodies, the Centro
Nacional de Control del Gas Natural (“CENAGAS”), which regulates the natural gas storage and transportation
system, and the Energy Regulation Commission (CRE), to adopt certain measures that would have put
pressure on CENAGAS’ customers to buy imported natural gas from CFE, Pemex or other state-controlled
providers, to the detriment of private suppliers. If adopted, those measures would have affected the purchase
of energy for certain natural gas injection points in the U.S.-Mexican border. Tubos de Acero de México S.A.
(“Tamsa”) challenged this initiative in court and obtained injunctive relief against the application of those
measures. In January 2023, the Mexican Supreme Court of Justice confirmed the general suspension of
SENER’s resolution until a final decision is made on the lawfulness of the government’s measures. Uncertainty
remains as to whether the Mexican government or any of its decentralized bodies will seek any new reform of
the energy market rules and regulations or adopt any measure that may negatively affect the energy supply or
increase its cost. Any such new amendment or measures could negatively affect the operations of Tamsa
and/or Techgen S.A. de C.V. (“Techgen”), the power plant in which Tenaris holds a 22% equity interest and
which supplies electricity for most of our Mexican operations and, consequently, on the results of operations
and financial conditions of our businesses in Mexico.

In the past, our operations in Mexico were disrupted due to union-led stoppages resulting from an internal
dispute within the local union. Although our Mexican operations have not experienced any further disruptions
caused by employee stoppages since 2020, we cannot assure that further disruptions will not occur in the
future. Any future stoppage, strike, disruption of operations or new collective bargaining agreements could
result in lost sales and could increase our costs, thereby affecting our results of operations.
The Russia-Ukraine armed conflict may adversely affect our operations
On February 24, 2022, Russia launched a military attack on Ukraine. In response, the United States, the European Union
and the United Kingdom, among other countries, have imposed a wave of sanctions against certain Russian institutions,
companies and citizens. The Russian Government has retaliated by banning airlines from its airspace and has ordered
economic counter measures, including restrictions on residents transferring foreign currency abroad. Russia is a major
supplier of oil and gas in Europe and worldwide, and Russia and Ukraine are both major global suppliers of
internationally traded steelmaking raw materials and semi-finished steel products. As a result of the armed conflict and
related sanctions, energy and commodity prices have spiked upwards and foreign trade transactions involving Russian
and Ukrainian counterparties have been severely affected. Although it is hard to predict how energy and commodity
prices will behave as the conflict unfolds, higher prices and possible shortages of energy and raw materials used in our
steelmaking operations (including natural gas and electric energy, particularly in Europe, steel scrap, pig iron, DRI, hot
briquetted iron (“HBI”), ferroalloys, steel bars, coils and plates) would result in higher production costs and potential
plant stoppages, affecting our profitability and results of operations. As a result of the economic sanctions imposed on
Russia, we or our contractors (including shipping companies) may not be able to continue purchasing products from, or
making payments to, Ukrainian or Russian suppliers or counterparties; and we may not be able to promptly procure
such raw materials from other suppliers, or we may be required to purchase raw materials at increased prices.
In addition, we have suspended any sales to Russian customers or purchases from Russian suppliers that would breach
applicable sanctions, and we are exploring alternatives with respect to potential relocation or closure of our
representative office in Moscow, which is currently not operative. Furthermore, in March 2022, we recorded an
impairment in the amount of approximately $14.9 million, fully impairing our investment in our joint venture in Russia
with Severstal.
If we do not successfully implement our business strategy, our ability to grow, our competitive position and our sales
and profitability may suffer
We plan to continue implementing our business strategy of consolidating our position as a leading global supplier of
integrated product and service solutions to the energy and other industries and adapting to the energy transition
through reducing the carbon emissions in our operations and developing and supplying products and services for low-
carbon energy applications, as well as continuing to pursue strategic investment opportunities. Any of the components
of our overall business strategy could cost more than anticipated (including as a result of increasing regulatory
requirements aimed at transitioning to a lower-carbon economy), may not be successfully implemented or could be
delayed or abandoned. For example, we may fail to create sufficient differentiation in our Rig Direct® services to
compensate the added costs of providing such services, or fail to find suitable investment opportunities, including
acquisition targets that enable us to continue to grow and maintain or improve our competitive position.
Even if we successfully implement our business strategy, it may not yield the expected results, or decisions by our joint
venture partners may frustrate our initiatives. For example, in November 2022, we entered into an agreement with JFE
Holdings Inc. (“JFE”), our partner in NKKTubes K.K. (“NKKTubes”), to terminate our joint venture and liquidate
NKKTubes. For further information on the termination of the NKKTubes joint venture, please refer to note 35 “Other
relevant information - Agreement to terminate NKKTubes joint venture” of our audited consolidated financial
statements included in this annual report. In July 2022, we entered into an effective agreement to acquire Benteler
Steel & Tube Manufacturing Corporation, a U.S. producer of seamless steel pipes owned by Benteler International A.G.
(“Benteler”). The agreement provided, however, that either party could unilaterally terminate the agreement if the
conditions to closing had not been satisfied by January 3, 2023, and in February 2023, Benteler exercised its right to
unilaterally terminate, effective immediately, the acquisition agreement and, accordingly, the transaction did not
proceed. For further information, please refer to note 35 “Other relevant information - Agreement for acquisition of
Benteler Steel & Tube Manufacturing Corporation” of our audited consolidated financial statements included in this
annual report.

Future acquisitions, strategic partnerships and capital investments may not perform in accordance with expectations
or may disrupt our operations and hurt our profits
One element of our business strategy is to identify and pursue growth-enhancing strategic opportunities. As part of that
strategy, we regularly make significant capital investments and acquire interests in, or businesses of, various
companies. Consistent with our growth strategy, we intend to continue considering strategic acquisitions, investments
and partnerships from time to time to expand our operations and establish a local presence in our markets. We must
necessarily base any assessment of potential acquisitions, joint ventures and capital investments on assumptions with
respect to timing, profitability, market and customer behavior and other matters that may subsequently prove to be
incorrect. For example, we negotiated the terms for our $1.0 billion acquisition of IPSCO Tubulars Inc. (“IPSCO”) in early
2019 based on assumptions made at that time, but due to the length of the antitrust review process, we were able to
complete the acquisition only in 2020 under materially worse market circumstances. Furthermore, in November 2021
we reached a preliminary agreement with JFE to amicably terminate our joint venture and cease NKKTubes’ operations
in June 2022; management determined that the parties’ decision to terminate the NKKTubes joint venture constituted
an impairment indicator and accordingly conducted an impairment test, recognizing a charge of approximately $57
million, impacting NKKTubes’ property, plant and equipment and intangible assets. For more information, refer to note
5 “Impairment charge”, and note 35 “Other relevant information - Agreement to terminate NKKTubes joint venture,
both to our audited consolidated financial statements included in this annual report. Our past or future acquisitions,
significant investments and alliances may not perform in accordance with our expectations and could adversely affect
our operations and profitability. In addition, new demands on our existing organization and personnel resulting from
the integration of new acquisitions could disrupt our operations and adversely affect our operations and profitability.
Moreover, as part of future acquisitions, we may acquire assets that are unrelated to our business, and we may not be
able to integrate these assets or sell them under favorable terms and conditions.
Disruptions to our manufacturing processes could adversely affect our operations, customer service levels and
financial results
Our steel pipe manufacturing processes depend on the operation of critical steelmaking equipment, such as electric arc
furnaces (“EAF”), continuous casters, rolling mills, heat treatment and various operations that support them, such as
our power generation facilities. Despite the investments we make to maintain critical production equipment, such
equipment may incur downtime as a result of unanticipated failures or other events, such as fires, explosions, floods,
earthquakes, accidents and severe weather conditions.
Similarly, natural disasters or severe weather conditions, including those related to climate change could significantly
damage our production facilities and general infrastructure or affect the normal course of business. For example, our
Mexican production facility located in Veracruz is located in a region prone to earthquakes, and our Bay City facility in
Texas, United States is located in an area prone to strong winds and hurricanes, and occasional floods. More generally,
changing weather patterns and climatic conditions in recent years have added to the unpredictability and frequency of
natural disasters. For more information on the risks associated with climate-change, see “Risks Relating to Our Business
and Industry The physical risks resulting from climate change, including extreme weather conditions and shifts in
weather patterns, have in the past and may in the future adversely affect our operations and financial results”.
Our operations may also be adversely affected as a result of work stoppages or other labor conflicts. In the past, our
operations in Mexico were disrupted due to union-led stoppages resulting from an internal dispute within the local
union. Although our Mexican operations have not experienced any further disruptions caused by employee stoppages
since 2020, we cannot assure that further disruptions will not occur in the future. In addition, in some of the countries
in which we have significant production facilities (e.g., Argentina and Brazil), significant inflationary pressures and
higher tax burdens could increase labor demands and could eventually generate higher levels of labor conflicts, which
may result in operational disruptions.
In addition, epidemics and other public health crises may disrupt our operations. For example, in response to the
COVID-19 outbreak in 2020, several countries, including countries where Tenaris has operations (such as Argentina,
China, Colombia, Italy, Mexico, Saudi Arabia and the United States) took mitigation and containment measures,
including bans on business activities and temporary closure of industrial facilities and, accordingly, some of our facilities
or production lines were closed or shutdown during 2020.
Some of the previously described emergency situations could result in damage to property, delays in production or
shipments and, in extreme cases, death or injury to persons. Any of the foregoing could create liability for Tenaris. To

the extent that lost production or delays in shipments cannot be compensated for by unaffected facilities, such events
could have an adverse effect on our profitability and financial condition. Additionally, we do not carry business
interruption insurance, and the insurance we maintain for property damage and general liability may not be adequate
or available to protect us under such events, its coverage may be limited, or the amount of our insurance may be less
than the related loss. For more information on our insurance coverage see “Information on the Company Business
overview Insurance”.
We may be required to record a significant charge to earnings if we must reassess our goodwill or other assets as a
result of changes in assumptions underlying the carrying value of certain assets, particularly as a consequence of
deteriorating market conditions
Assets that are subject to amortization are reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount may not be recoverable. Intangible assets with indefinite useful life, including
goodwill, are subject to impairment tests following IAS 36. Impairment tests may result in impairment charges, as
shown below:
In 2020, we recognized goodwill for approximately $357 million in connection with our acquisition of IPSCO in
January 2020. As a result of the severe deterioration of business conditions and in light of the presence of
impairment indicators for our U.S. operations, we subsequently recorded impairment charges as of March 31,
2020, for an aggregate amount of approximately $622 million.
In December 2021, we recorded a charge of $57 million in connection with the expected termination of the
NKKTubes joint venture.
In March 2022, in light of the armed conflict in Ukraine and the designation of Severstal’s controlling shareholder
as a person subject to EU and UK sanctions, we recorded an impairment in the amount of approximately $14.9
million, fully impairing our investment in our joint venture in Russia with Severstal. For more information on
Tenaris’s operations involving Russia, see “Key Information Risk Factors Risks Relating to Our Business and
Industry The Russia-Ukraine armed conflict may adversely affect our operations”.
In September, 2022, mainly due to the lower expectations for steel demand and market steel prices, together with
a worsened global macroeconomic situation that derived in an increase in discount rates, we wrote down our
investment in Usinas Siderúrgicas de Minas Gerais S.A.(“Usiminas”) by $19.1 million.
In December 2022, in the presence of impairment indicators, the Company conducted impairment tests, reviewed
the values of certain idle assets in its subsidiaries and recorded impairment charges of $76.7 million.
As of December 31, 2022, goodwill amounted to $1,085 million corresponding mainly ($920 million) to the acquisition
of Hydril Company (“Hydril”) in 2007 and is allocated to Hydril, Siderca and Tamsa cash generating units (“CGU”).
For more information on impairment charges, please refer to note 5 “Impairment charge”, note 13 “Investments in
non-consolidated companies” and note 35 “Other relevant information - Agreement to terminate NKKTubes joint
venture to our audited consolidated financial statements included in this annual report.
Our results of operations and financial condition could be adversely affected by movements in exchange rates
As a global company we manufacture and sell products throughout the world and a portion of our business is carried
out in currencies other than the U.S. dollar, which is the Company’s functional and presentation currency. As a result,
we are exposed to foreign exchange rate risk. Changes in currency values and foreign exchange regulations could
adversely affect our financial condition and results of operations. For information on our foreign exchange rate risk,
please see “Quantitative and Qualitative Disclosure About Market Risk Foreign Exchange Rate Risk”.
Changes in applicable tax regulations and resolutions of tax disputes could negatively affect our financial results
We are subject to tax laws in numerous foreign jurisdictions where we operate. The integrated nature of our worldwide
operations can produce conflicting claims from revenue authorities in different countries as to the profits to be taxed in
the individual countries, including disputes relating to transfer pricing. Most of the jurisdictions in which we operate
have double tax treaties with foreign jurisdictions, which provide a framework for mitigating the impact of double

taxation on our results. However, mechanisms developed to resolve such conflicting claims are largely untried and can
be expected to be very lengthy.
In recent years, tax authorities around the world have increased their scrutiny of companies’ tax filings and have
become more rigid in exercising any discretion they may have. As part of this, in 2015, the Organization for Economic
Co-operation and Development (“OECD”) proposed a number of tax law changes under its Base Erosion and Profit
Shifting (“BEPS”) Action Plans to address issues of transparency, coherence and substance. Most of the countries in
which we operate have already implemented those changes within their own domestic tax legislations.
In 2019, the OECD launched a new initiative on behalf of the G20 under the format of a two pillars solution: Pillar One,
aimed at minimizing profit shifting by working towards a global tax framework that ensures that corporate income
taxes are paid where consumption takes place, and Pillar Two, aimed at introducing a global standard on minimum
taxation, both combined with new tax dispute resolution processes. This project achieved OECD political consensus in
October 2021. Pillar Two is scheduled to apply starting in 2024, while detailed principles on Pillar One are still under
discussion.
At the EU level, the European Commission adopted in 2016 its Anti-Tax Avoidance Directive (“ATAD”), later updated,
modified and expanded by ATAD 2, which seeks to prevent tax avoidance by companies and to ensure that companies
pay appropriate taxes in the markets where profits are effectively made and business is effectively performed. In
addition, the European Commission drafted a directive aiming to avoid the use of shell entities (ATAD 3), which, if
approved and adopted by all EU members, would become effective in 2024. Also, the European Commission adopted in
December 2022 another directive to impose a global minimum taxation for multinational companies in the Union,
following Pillar Two OECD’s initiative. The new directive would become effective as from 2024.
Changes to tax laws and regulations in the countries where we operate require us to continually assess our
organizational structure and could lead to increased risk of international tax disputes.
Our interpretation and application of the tax laws could differ from that of the relevant governmental taxing authority,
which could result in the payment of additional taxes, penalties or interest, negatively affecting our profitability and
financial condition. Significant uncertainties remain in relation to the potential adoption of the new regulations that
might result from evolving initiatives like those launched by the OECD and the EU in relation to international taxation
that could impact negatively our financial condition, results of operations and cash flows.
If we do not comply with laws and regulations designed to combat corruption in countries in which we sell our
products, we could become subject to governmental investigations, fines, penalties or other sanctions and to private
lawsuits and our sales and profitability could suffer
We operate and conduct business globally, including in certain countries known to experience high levels of corruption.
Although we are committed to conducting business in a legal and ethical manner in compliance with local and
international statutory requirements and standards applicable to our business, there is a risk that our employees,
representatives, associates, affiliates, or other persons may take actions that violate applicable laws and regulations
that generally prohibit offering or making of improper payments to any individual, including to government officials, for
the purpose of obtaining a benefit or undue advantage or keeping business, as stated by the U.S. Foreign Corrupt
Practices Act (“FCPA”). Investigations by government authorities may occupy considerable management time and
attention, weaken company compliance culture and result in significant expenditures, fines, penalties or other
sanctions, as well as private lawsuits. For information on matters related to the Company Business Conduct Compliance
Program, please refer to our website on the matter https://www.tenaris.com/en/sustainability/governance-and-
ethics/.
For example, upon learning that Brazilian, Italian and Swiss authorities were investigating whether certain payments
were made prior to 2014 from accounts of entities presumably associated with affiliates of the Company to accounts
allegedly linked to individuals related to Petróleo Brasileiro S.A. (“Petrobras”) and whether any such payments were
intended to benefit Confab Industrial S.A. (“Confab”), the Audit Committee of the Company's board of directors
engaged external counsel in connection with the Company’s review of these matters. In addition, the Company
voluntarily notified the U.S. Securities and Exchange Commission (“SEC”) and the U.S. Department of Justice (“DOJ”) in
October 2016. The Company conducted, with the assistance of external counsel, an internal investigation and found no
evidence corroborating any involvement by the Company or its directors, officers or employees in respect of improper
payments. An internal investigation commissioned by Petrobras also found no evidence that Confab obtained any
unfair commercial benefit or advantage from Petrobras in return for payments, including improperly obtained
contracts. On June 2, 2022, the Company resolved the investigation by the SEC and the DOJ informed that it had closed

its parallel inquiry without taking action. Under the settlement with the SEC, the Company neither admits nor denies
the SEC’s findings and on June 24, 2022, paid $53.1 million in disgorgement and prejudgment interest and $25 million
for a civil penalty to conclude the matter.
For information on matters related to the Petrobras-related proceedings and claims, please see “Consolidated
Statements and Other Financial Information Legal Proceedings”.
The cost of complying with environmental regulations and potential environmental and product liabilities may
increase our operating costs and negatively impact our business, financial condition, results of operations and
prospects
We are subject to a wide range of local, state, provincial and national laws, local and international regulations, permit
requirements and decrees relating to the protection of human health and the environment, including laws and
regulations relating to hazardous materials and radioactive materials and environmental protection governing air
emissions, water discharges and waste management. Laws and regulations protecting the environment have become
increasingly complex and more stringent and expensive to implement in recent years. Additionally, international
environmental requirements vary. While standards in the European Union, Canada, and Japan are generally
comparable to (or more stringent than) U.S. standards, other nations, particularly developing nations, including China,
have substantially fewer or less rigorous requirements that may give competitors in such nations a competitive
advantage. It is possible that any international agreement to regulate emissions may provide exemptions and lesser
standards for developing nations. In such case, we may be at a competitive disadvantage relative to competitors having
more or all of their production in such developing nations.
Environmental laws and regulations may, in some cases, impose strict liability rendering a person liable for damages to
natural resources or threats to public health and safety without regard to negligence or fault. Some environmental laws
provide for joint and several strict liability for remediation of spills and releases of hazardous substances. These laws
and regulations may expose us to liability for the conduct of or conditions caused by others or for acts that were in
compliance with all applicable laws at the time they were performed.
Compliance with applicable requirements and the adoption of new requirements could have a material adverse effect
on our consolidated financial condition, results of operations or cash flows. The costs and ultimate impact of complying
with environmental laws and regulations are not always clearly known or determinable since regulations under some of
these laws have not yet been promulgated or are undergoing revision. The expenditures necessary to remain in
compliance with these laws and regulations, including site or other remediation costs, or costs incurred as a result of
potential violations of environmental laws could have a material adverse effect on our financial condition and
profitability. While we incur and will continue to incur expenditures to comply with applicable laws and regulations,
there always remains a risk that environmental incidents or accidents may occur that may negatively affect our
reputation or our operations.
Our oil and gas casing, tubing and line pipe products are sold primarily for use in oil and gas drilling, gathering,
transportation, processing and power generation facilities, which are subject to inherent risks, including well failures,
line pipe leaks, blowouts, bursts and fires, that could result in death, personal injury, property damage, environmental
pollution or loss of production. Any of these hazards and risks can result in environmental liabilities, personal injury
claims and property damage from the release of hydrocarbons.
Defects in specialty tubing products could result in death, personal injury, property damage, environmental pollution,
damage to equipment and facilities or loss of production.
We normally warrant the oilfield products and specialty tubing products we sell or distribute in accordance with
customer specifications, but as we pursue our business strategy of providing customers with additional services, such as
Rig Direct®, we may be required to warrant that the goods we sell and services we provide are fit for their intended
purpose. Actual or claimed defects in our products may give rise to claims against us for losses suffered by our
customers and expose us to claims for damages. The insurance we maintain will not be available in cases of gross
negligence or willful misconduct, in other cases may not be adequate or available to protect us in the event of a claim,
its coverage may be limited, canceled or otherwise terminated, or the amount of our insurance may be less than the
related impact on enterprise value after a loss. Similarly, our sales of tubes and components for the automotive
industry subject us to potential product liability risks that could extend to being held liable for the costs of the recall of
automobiles sold by car manufacturers and their distributors.

Limitations on our ability to protect our intellectual property rights, including our trade secrets, could cause a loss in
revenue and any competitive advantage we hold
Some of our products or services, and the processes we use to produce or provide them, have been granted patent
protection, have patent applications pending, or are trade secrets. Our business may be adversely affected if our
patents are unenforceable, the claims allowed under our patents are not sufficient to protect our technology, our
patent applications are denied or our trade secrets are not adequately protected. Our competitors may be able to
independently develop technology that is similar to ours without infringing on our patents or gaining access to our
trade secrets, which could adversely affect our financial condition, results of operations and cash flows.
Cyberattacks could have a material adverse impact on our business and results of operations
We rely heavily on information systems to conduct our operations and digital technologies have an increasingly
significant role across our business. Although we devote significant resources to protect our systems and data and we
continually monitor external developments and available information on threats and security incidents, we have
experienced and will continue to experience varying degrees of cyber incidents in the normal conduct of our business,
which may occasionally include sophisticated cybersecurity threats such as unauthorized access to data and systems,
loss or destruction of data, computer viruses or other malicious code, phishing, spoofing and/or cyberattacks. These
threats often arise from numerous sources, not all of which are within our control, such as fraud or malice from third
parties, including fraud involving business email compromises, failures of computer servers or other accidental
technological failures, electrical or telecommunication outages or other damage to our property or assets.
Cybersecurity threats represent one of the most significant risks for most businesses. Cyberattack attempts continued
to increase throughout 2022 in the post-pandemic context, primarily due to widespread adoption of remote work
practices among our employees, customers and suppliers and the increasing digitalization of work. Cybersecurity was a
major topic of discussion at the World Economic Forum's annual 2023 meeting in Davos, Switzerland, where experts
warned that cyberattacks are increasing in sophistication and frequency and called for a global response to
cybersecurity threats. Microsoft has indicated that the manufacturing industry is the industry most exposed to
ransomware attacks. For example, in 2022, we suffered seven cybersecurity attacks, none of which led to known
breaches of our business-critical IT systems and, as such, did not result in any material business impact. In this context,
we continue to seek to improve cybersecurity controls, processes and procedures to monitor, detect and respond to
hacking, malware infection, cybersecurity compromise and other risks. In addition, we continued with cybersecurity
awareness and ethical phishing campaigns aimed at protecting us against cyberthreats, and tailored cybersecurity
training programs addressed to our executives and employees. In order to improve the capacity to bounce back quickly
from a cyber-incident, Tenaris has also adopted cyber-resilience as part of its cybersecurity strategy.
Given the rapidly evolving nature of cyberthreats, there can be no assurance that the systems we have designed to
prevent or limit the effects of cyber incidents or attacks will be adequate, and such incidents or attacks could have a
material adverse impact on our systems. While we attempt to mitigate these risks, we remain vulnerable to additional
known or unknown threats, including theft, misplacement or loss of data, programming errors, employee errors and/or
dishonest behavior that could potentially lead to the compromising of sensitive information, improper use of our
systems or networks, as well as unauthorized access, use, disclosure, modification or destruction of such information,
systems and/or networks. If our systems for protecting against cybersecurity risks are circumvented or breached, this
could also result in disruptions to our business operations (including but not limited to, defective products, production
downtimes or loss of productivity), access to our financial reporting systems, the loss of access to critical data or
systems, misuse or corruption of critical data and proprietary information (including our intellectual property and
customer data), as well as damage to our reputation with our customers and the market, failure to meet customer
requirements, customer dissatisfaction and/or regulatory fines and penalties (including for inadequate protection of
personal data and/or failure to notify the competent authorities for such breach), damages and harm to the
environment and people, or other financial costs and losses. In addition, given that cybersecurity threats continue to
evolve, we will be required to devote additional resources in the future to enhance our protective measures or to
investigate and/or remediate any cybersecurity vulnerabilities. Additionally, although we have considered contract
insurance coverage options for cyber risk, we do not currently maintain cybersecurity insurance, and the insurance we
carry for property damage and general liability may not be adequate or available to protect us from damages derived
from cyberthreats or coverage may be limited. Moreover, any investigation of a cyberattack would take time before
completion, during which we would not necessarily know the extent of the actual or potential harm or how best to
remediate it, and certain errors or actions could be repeated or compounded before duly discovered and remediated
(all or any of which could further increase the costs and consequences arising out of such cyberattack). In addition,
failure to adequately and timely monitor our hardware and software systems and applications to prevent or manage

technology obsolescence risks may result in increased costs, increased operational risk of service failure, loss of
technology competitiveness and reputational risk.
Risks Relating to the Structure of the Company
The Company’s dividend payments depend on the results of operations and financial condition of its subsidiaries and
could be restricted by legal, contractual or other limitations or tax changes
The Company is a holding company and conducts all its operations through subsidiaries. Dividends or other
intercompany transfers of funds from those subsidiaries are the Company’s primary source of funds to pay its expenses,
debt service and dividends and to repurchase shares or ADSs.
The ability of the Company’s subsidiaries to pay dividends and make other payments to us will depend on their results
of operations and financial condition. If earnings and cash flows of the Company’s operating subsidiaries are
substantially reduced, the Company may not be in a position to meet its operational needs or to pay dividends. In
addition, such dividends and other payments could be restricted by applicable corporate and other laws and
regulations, including those imposing foreign exchange controls or restrictions on the repatriation of capital or the
making of dividend payments, and agreements and commitments of such subsidiaries. For information concerning
potential restrictions on our ability to collect dividends from certain subsidiaries, see “Risks Relating to Our Business
and Industry Adverse economic or political conditions in the countries where we operate or sell our products and
services may decrease our sales or disrupt our manufacturing operations, thereby adversely affecting our revenues,
profitability and financial condition” and “Financial Information – Consolidated Statements and Other Financial
Information Dividend Policy”.
The Company’s ability to pay dividends to shareholders is subject to legal and other requirements and restrictions in
effect at the holding company level. For example, the Company may only pay dividends out of net profits, retained
earnings and distributable reserves and premiums, each as defined and calculated in accordance with Luxembourg law
and regulations. In addition, the Company’s dividend distributions (which are currently imputed to a special tax reserve
and are therefore not subject to Luxembourg withholding tax) may be subject to Luxembourg withholding tax if current
Luxembourg tax law were to change.
The Company’s controlling shareholder may be able to take actions that do not reflect the will or best interests of
other shareholders
As of the date of this annual report, San Faustin beneficially owned 60.45% of our outstanding voting shares. Rocca &
Partners Stichting Administratiekantoor Aandelen San Faustin (“RP STAK”), holds voting rights in San Faustin sufficient
to control San Faustin. As a result, RP STAK is indirectly able to elect a substantial majority of the members of the
Company’s board of directors and has the power to determine the outcome of most actions requiring shareholder
approval, including, subject to the requirements of Luxembourg law, the payment of dividends. The decisions of the
controlling shareholder may not reflect the will or best interest of other shareholders. In addition, the Company’s
articles of association permit the Company’s board of directors to waive, limit or suppress preemptive rights in certain
cases. Accordingly, the Company’s controlling shareholder may cause its board of directors to approve in certain cases
an issuance of shares for consideration without preemptive rights, thereby diluting the minority interest in the
Company. See “Risks Relating to shares and ADSs Holders of shares and ADSs in the United States may not be able to
exercise preemptive rights in certain cases”.
Risks Relating to shares and ADSs
Holders of shares or ADSs may not have access to as much information about the Company as they would in the case
of a U.S. domestic issuer
There may be less publicly available information about the Company than is regularly published by or about U.S.
domestic issuers. Also, corporate and securities regulations governing Luxembourg companies may not be as extensive
as those in effect in other jurisdictions and U.S. securities regulations applicable to foreign private issuers, such as the
Company, differ in certain respects from those applicable to U.S. domestic issuers. Furthermore, IFRS, the accounting
standards in accordance with which the Company prepares its consolidated financial statements, differ in certain
material aspects from U.S. GAAP. For a summary of the significant ways in which the Company’s corporate governance
practices differ from the corporate governance standards required for domestic companies by the New York Stock
Exchange (“NYSE”), see “Corporate Governance Statement Summary of differences with NYSE standards”.

Graphics
Annual Report 2022

Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights afforded to
shareholders
Certain shareholders’ rights under Luxembourg law, including the rights to participate and vote at general meetings of
shareholders, to include items on the agenda for the general meetings of shareholders, to receive dividends and
distributions, to bring actions, to examine our books and records and to exercise appraisal rights may not be available
to holders of ADSs, or may be subject to restrictions and special procedures for their exercise, as holders of ADSs only
have those rights that are expressly granted to them in the deposit agreement. Deutsche Bank Trust Company
Americas, as depositary under the ADS deposit agreement, or the Depositary, through its custodian agent, is the
registered shareholder of the deposited shares underlying the ADSs, and therefore only the Depositary can exercise the
shareholders’ rights in connection with the deposited shares. For example, if the Company makes a distribution in the
form of securities, the Depositary is allowed, at its discretion, to sell the right to acquire those securities on your behalf
and to instead distribute the net proceeds to you. Also, under certain circumstances, such as the Company’s failure to
provide the Depositary with voting materials on a timely basis, you may not be able to vote at general meetings of
shareholders by giving instructions to the Depositary. If the Depositary does not receive voting instructions from the
holder of ADSs by the prescribed deadline, or the instructions are not in proper form, then the Depositary shall deem
such holder of ADSs to have instructed the Depositary to vote the underlying shares represented by ADSs in favor of
any proposals or recommendations of the Company (including any recommendation by the Company to vote such
underlying shares on any given issue in accordance with the majority shareholder vote on that issue), for which
purposes the Depositary shall issue a proxy to a person appointed by the Company to vote such underlying shares
represented by ADSs in favor of any proposals or recommendations of the Company. Under the ADS deposit
agreement, no instruction shall be deemed given and no proxy shall be given with respect to any matter as to which the
Company informs the Depositary that (i) it does not wish such proxy given, (ii) it has knowledge that substantial
opposition exists with respect to the action to be taken at the meeting, or (iii) the matter materially and adversely
affects the rights of the holders of ADSs.
Holders of shares and ADSs in the United States may not be able to exercise preemptive rights in certain cases
Pursuant to Luxembourg corporate law, existing shareholders of the Company are generally entitled to preferential
subscription rights (preemptive rights) in the event of capital increases and issues of shares against cash contributions.
Under the Company’s articles of association, the board of directors has been authorized to waive, limit or suppress such
preemptive subscription rights. Notwithstanding the waiver of any preemptive subscription rights, any issuance of
shares for cash within the limits of the authorized share capital shall be subject to the preemptive subscription rights of
existing shareholders, except (i) any issuance of shares (including without limitation, the direct issuance of shares or
upon the exercise of options, rights convertible into shares, or similar instruments convertible or exchangeable into
shares) against a contribution other than in cash; and (ii) any issuance of shares (including by way of free shares or at
discount), up to an amount of 1.5% of the issued share capital of the Company, to directors, officers, agents, employees
of the Company, its direct or indirect subsidiaries or its affiliates (or, collectively, the beneficiaries), including without
limitation, the direct issuance of shares or upon the exercise of options, rights convertible into shares or similar
instruments convertible or exchangeable into shares, issued for the purpose of compensation or incentive of the
beneficiaries or in relation thereto (which the board of directors shall be authorized to issue upon such terms and
conditions as it deems fit). For further details, see “Corporate Governance Statement Corporate Governance”.
Holders of ADSs in the United States may, in any event, not be able to exercise any preemptive rights, if granted, for
shares underlying their ADSs unless additional shares and ADSs are registered under the U.S. Securities Act of 1933, as
amended, (“Securities Act”), with respect to those rights, or an exemption from the registration requirements of the
Securities Act is available. The Company intends to evaluate, at the time of any rights offering, the costs and potential
liabilities associated with the exercise by holders of shares and ADSs of the preemptive rights for shares, and any other
factors it considers appropriate at the time, and then to make a decision as to whether to register additional shares.
The Company may decide not to register any additional shares, requiring a sale by the Depositary of the holders’ rights
and a distribution of the proceeds thereof. Should the Depositary not be permitted or otherwise be unable to sell
preemptive rights, the rights may be allowed to lapse with no consideration to be received by the holders of the ADSs.
It may be difficult to obtain or enforce judgments against the Company outside Luxembourg
The Company is a société anonyme organized under the laws of the Grand Duchy of Luxembourg, and most of its assets
are located in other jurisdictions. Furthermore, most of the Company’s directors and officers reside in other
jurisdictions. As a result, investors may not be able to effect service of process upon the Company or its directors or
officers. Investors may also not be able to enforce against the Company or its directors or officers in the investors’

domestic courts, judgments predicated upon the civil liability provisions of the domestic laws of the investors’ home
countries. Likewise, it may be difficult for investors not domiciled in Luxembourg to bring an original action in a
Luxembourg court predicated upon the civil liability provisions of other securities laws, including U.S. federal securities
laws, against the Company, its directors or its officers. There is also uncertainty with regard to the enforceability of
original actions of civil liabilities predicated upon the civil liability provisions of securities laws, including U.S. federal
securities laws, outside the jurisdiction where such judgments have been rendered; and enforceability will be subject to
compliance with procedural requirements under applicable local law, including the condition that the judgment does
not violate the public policy of the applicable jurisdiction.

Tenaris
Tenaris began with the formation of Siderca, the sole Argentine producer of seamless steel pipe products, by San
Faustin’s predecessor in Argentina in 1948. We acquired Siat S.A., an Argentine welded steel pipe manufacturer, in
1986. We grew organically in Argentina and then, in the early 1990s, began to evolve beyond this initial base into a
global business through a series of strategic investments. As of the date of this annual report, our investments include
controlling interests in several manufacturing companies:

Business Overview Capital Expenditure Program.
Business Overview
Our business strategy is to consolidate our position as a leading global supplier of integrated product and service
solutions to the energy and other industries and to adapt to the energy transition through reducing the carbon
emissions in our operations and on developing and supplying products and services for low-carbon energy applications
by:
pursuing strategic investment opportunities in order to further strengthen our presence in local and global
markets;
expanding our comprehensive range of products and developing new products designed to meet the needs of
customers operating in challenging environments, including low carbon energy applications, such as hydrogen
and carbon capture and storage;
enhancing our offering of technical, digital and supply chain integration services designed to enable customers
to optimize well planning and integrity, simplify operations and reduce overall operating costs; and
securing an adequate supply of production inputs and reducing the manufacturing costs and carbon intensity of
our core products.
Pursuing strategic investment opportunities and alliances
We have a solid record of growth through strategic investments and acquisitions. We pursue selective strategic
investments and acquisitions as a means to expand our operations and presence in select markets, enhance our global
competitive position and capitalize on potential operational synergies. For example:
In January 2020, we acquired IPSCO, a North American manufacturer of seamless and welded steel pipes, from
PAO TMK (“TMK”), with facilities located mainly in the midwestern and northeastern regions of the United
States, and a steel shop in Koppel, Pennsylvania.
In December 2020 we entered into a joint venture with Inner Mongolia Baotou Steel Union Co., Ltd. (“Baotou
Steel”) to build a premium connection threading facility to finish steel pipes produced by our joint venture
partner in Baotou, China, for sale to the domestic market. The plant started operations in the first quarter of
2022.
We are building a wind farm in Argentina at a cost of approximately $200 million, which is expected to reduce
Tenaris’s CO
2
emissions in that country by around 150,000 tons per year, and supply close to 50% of the energy
requirements at the integrated seamless pipe mill in Campana, Argentina. This investment is expected to be
completed during 2023.
Our track record on the acquisition of companies is described above in “History and Development of the Company
Tenaris”.
Expanding our range of products including the development of new products for the energy transition
We have developed an extensive range of high-value products suitable for most of our customers’ operations using our
network of specialized R&D facilities and by investing in our manufacturing facilities. As our customers expand their
operations, we seek to supply high-value products that reduce costs and enable them to operate safely in challenging
environments, including those for low-carbon applications associated with the energy transition.
As suppliers of tubular products and services to the energy industry, the energy transition currently underway provides
an important opportunity to develop new products and services for potentially fast-growing segments like hydrogen
transportation and storage, carbon capture and sequestration (“CCS”) and geothermal installations. We have
developed a range of technologies that are particularly suited for use in hydrogen storage and transportation, where
we are seeing fast growth in demand for large, high-pressure vessels used in the build out of hydrogen refueling
stations for heavy-duty vehicles and buses in Europe and California. We are also seeing increasing interest from
customers for developing CCS projects.

Enhancing our offering of technical, digital and supply chain integration services - Rig Direct® - and extending their
global deployment
We continue to enhance our offering of Rig Direct® services and extend their deployment worldwide. For many years,
we have provided these services, managing customer inventories and directly supplying pipes to their rigs on a just-in-
time basis, complemented by technical advice and assistance on the selection of materials and their use in the field, in
markets like Mexico and Argentina. In response to changes in market conditions and the increased focus of customers
on reducing costs and improving the efficiency of their operations, the extent and deployment of our Rig Direct®
services has been extended throughout North America and in other markets around the world (e.g., Colombia, North
Sea, Romania and the United Arab Emirates) and now include digital and more extensive supply chain integration
services. Through the provision of Rig Direct® services, we seek to integrate our operations with those of our customers
using digital technologies to shorten the supply chain and simplify operational and administrative processes, as well as
technical services for well planning and well integrity, to reduce costs, improve safety and minimize environmental
impact. They are also intended to differentiate us from our competitors and further strengthen our relationships with
customers worldwide through long-term agreements.
Securing inputs for our manufacturing operations
We seek to secure our existing sources of raw material and energy inputs, and to gain access to new sources of low-cost
inputs which can help us maintain or reduce the cost of manufacturing our core products and reduce the carbon
emissions intensity of our operations over the long term. We aim to achieve a vertically integrated value chain for our
production. To this end, we purchase most of our supplies through Exiros, a specialized procurement company the
ownership of which we share with Ternium. Exiros offers us integral procurement solutions, supplier sourcing activities;
category organized purchasing; suppliers’ performance administration; and inventory management. In addition,
through IPSCO’s acquisition, we have secured a steel shop in Koppel, Pennsylvania, which is our first steel shop in the
United States and provides vertical integration through domestic production of a significant part of our steel bar needs
in the United States.
Our Competitive Strengths
We believe our main competitive strengths include:
our global production, commercial and distribution capabilities, offering a full product range with flexible supply
options backed up by local service capabilities in important oil and gas producing and industrial regions around
the world;
our ability to develop, design and manufacture technologically advanced products;
our solid and diversified customer base and historic relationships with major international oil and gas companies
around the world, and our strong and stable market shares in most of the countries in which we have
manufacturing operations;
our proximity to our customers;

Business Segments
Tenaris has one major business segment, Tubes, which is also the reportable operating segment. All other business
activities and operating segments that are not required to be separately reported, are disclosed in the “Others”
segment.
The Tubes segment includes the production and sale of both seamless and welded steel tubular products and related
services mainly for the energy industry, particularly casing and tubing used in oil and gas drilling operations, and line
pipe used in the transportation and processing of oil and gas, but also other industrial applications. Our production

processes include the production of steel and its transformation into tubular products. Business activities included in
this segment are mainly dependent on the oil and gas industry worldwide, as this industry is a major consumer of steel
pipe products. Demand for steel pipe products from the energy industry has historically been volatile and depends
primarily upon the number of oil and natural gas wells being drilled, completed and reworked, and the depth and
drilling conditions of such wells. Major oil and gas companies are beginning to adapt their strategies and increase their
investments in renewable energies to address the energy transition while maintaining their capability to meet market
demand for oil and gas and reducing the emissions from their operations. As the energy transition advances, demand
for our products and services from low-carbon energy applications, such as geothermal, hydrogen and carbon capture
and storage, is expected to increase while demand for oil and gas applications may decrease.
Sales are generally made to end users, with exports being done through a centrally managed global distribution
network and domestic sales made through local subsidiaries.
The Others segment includes all other business activities and operating segments related to the production and sale
of sucker rods, tubes used for plumbing and construction applications, coiled tubing used in oil and gas extraction
activities, oil and gas services including fracking and coiled tubing services in Argentina, the sale of energy and raw
materials that exceed our internal requirements, and industrial equipment of various specifications and for diverse
applications (this business was discontinued in 2022).
For more information on our business segments, see “II C. Accounting Policies Segment information” to our audited
consolidated financial statements included in this annual report.
Our Products
Our principal finished products are seamless and welded steel casing and tubing, line pipe and various other mechanical
and structural steel pipes for different uses. Casing and tubing are also known as oil country tubular goods (“OCTG”).
We manufacture our steel pipe products in a wide range of specifications, which vary in diameter, length, thickness,
finishing, steel grades, coating, threading and coupling. For more complex applications, including high pressure and high
temperature applications, seamless steel pipes are usually specified and, for some standard applications, welded steel
pipes can also be used. In addition to oil and gas applications, many of our products can also be used in low-carbon
energy applications, such as geothermal, hydrogen and carbon capture and storage.
Casing. Steel casing is used to sustain the walls of oil and gas wells during and after drilling.
Tubing. Steel tubing is used to conduct crude oil and natural gas to the surface after drilling has been completed.
Line pipe. Steel line pipe is used to transport crude oil and natural gas from wells to refineries, storage tanks and
loading and distribution centers.
Mechanical and structural pipes. Mechanical and structural pipes are used by general industry for various applications,
including the transportation of other forms of gas and liquids under high pressure.
Cold-drawn pipe. The cold-drawing process permits the production of pipes with the diameter and wall thickness
required for use in boilers, superheaters, condensers, heat exchangers, automobile production and several other
industrial applications.
Premium joints and couplings. Premium joints and couplings are specially designed connections used to join lengths of
steel casing and tubing for use in high temperature or high pressure environments. A significant portion of our steel
casing and tubing products are supplied with premium joints and couplings. We own an extensive range of premium
connections, and following the integration of the premium connections business of Hydril, we have marketed our
premium connection products under the TenarisHydril brand name. In addition, we hold licensing rights to
manufacture and sell the Atlas Bradford range of premium connections outside the United States and, since our
acquisition of IPSCO in January 2020, we own the Ultra and “TORQ” ranges of premium connections.
Coiled tubing. Coiled tubing is used for oil and gas drilling and well workovers and for subsea pipelines.
Other products. We also manufacture sucker rods used in oil extraction activities, tubes used for plumbing and
construction applications, oilfield / hydraulic fracturing services, energy and raw materials that exceed our internal
requirements, and industrial equipment (discontinued in 2022).

Effective annual production capacity is calculated based on standard productivity of production lines, theoretical product mix allocations, the
maximum number of possible working shifts and a continued flow of supplies to the production process.
In 2021, our production capacity for welded pipes decreased as a result of the dismantling of our Canadian facility and
one of our U.S. facilities. Part of the equipment dismantled at our Calgary facility in Alberta was modernized and
relocated along with new equipment to our Sault Ste. Marie facility in Ontario, as part of an investment in a
repositioning plan for our industrial activities, which was completed in the second half of 2022.

Furthermore, in 2022 we revised the capacity of some of our seamless and welded pipe mills in the United States
following the integration of the IPSCO plants acquired in 2020 and taking into account current market and production
mix of products. Consequently, total seamless capacity increased slightly in respect to the previous year, while welded
capacity shows a slight reduction. Capacity of seamless pipes includes NKKTubes which ceased operations in June 2022.

In December 2020 we entered into an agreement with Baotou Steel to build a steel pipe premium connection threading
plant to produce OCTG products in Baotou, China. Under the agreement, Tenaris holds 60% of shares in the joint-
venture company, while Baogang Steel Pipes (“Baogang”) owns the remaining 40%. The plant started operations in the
first quarter of 2022.
In addition, in Indonesia, we hold 89.17% of SPIJ, an Indonesian OCTG processing business with heat treatment,
premium connection threading facilities, coupling shop and a quality-testing laboratory, including an ultrasonic testing
machine, which has an annual processing capacity of approximately 120,000 tons. We also have a premium joints
accessories threading facility in the state of Batam, which we integrated into our operations following the acquisition of
Hydril.
Tenaris’s former seamless pipe manufacturing facility in Japan, located in the Keihin steel complex owned by JFE, was
operated by NKKTubes, a company owned 51% by Tenaris and 49% by JFE. The NKKTubes facility produced a wide
range of carbon, alloy and stainless steel pipes for the local market and high value-added products for export markets
with an effective annual production capacity of approximately 260,000 tons. Following JFE’s decision to permanently
cease some of its operations in the Kehin complex, where NKKTubes was located, Tenaris and JFE engaged in
discussions and ultimately determined that the project was no longer economically sustainable. Accordingly, the parties

agreed to terminate amicably their joint venture and liquidate NKKTubes, which ceased operations on June 30, 2022.
The liquidation process of NKKTubes started on November 30, 2022 and is expected to be completed in 2023. For
further information on the termination of the NKKTubes joint venture, please refer to note 35 “Other relevant
information - Agreement to terminate NKKTubes joint venture” of our audited consolidated financial statements
included in this annual report.
Production Facilities Others
We have facilities for the manufacturing of sucker rods in Villa Mercedes (San Luis, Argentina), Moreira Cesar (São
Paulo, Brazil), Veracruz (Mexico), Campina (Romania) and Conroe (Texas, United States). Our total annual
manufacturing capacity of sucker rods is approximately 3.1 million units.
In March 2021, Tenaris acquired fracking equipment from U.S.-based oil services company, Baker Hughes, in Argentina,
allowing us to step up our services portfolio in the Vaca Muerta shale deposit on an expected rise in activity. In
connection with this transaction, we acquired a pressure pumping fleet, a coiled tubing unit and related equipment.
In March, 2022, we reorganized the activities at our Confab Equipamentos industrial facility in Moreira César,
Pindamonhangaba, São Paulo, Brazil. Our Brazilian subsidiaries discontinued the manufacturing of industrial equipment
to focus their activities entirely on the production of welded products, sucker rods, coatings and accessories.
In Italy, we have the Piombino facility, which covers an area of approximately 67 hectares and comprises a hot-dip
galvanizing line and associated finishing facilities. Production is focused on finishing of small diameter seamless pipes
for construction and plumbing applications in the domestic market, such as residential water, gas transport and
firefighting. The Piombino facility has an annual production capacity of approximately 100,000 tons.
In addition, we have specialized facilities in the Houston area producing coiled tubing and umbilical tubing:
A coiled tubing facility of approximately 150,000 square feet of manufacturing space on 4 hectares. The plant
consists of two mills and coating operations capable of producing coiled tubing products in various grades, sizes
and wall thicknesses. A new continuous heat treatment line has been recently installed.
An umbilical tubing facility of approximately 85,000 square feet of manufacturing space on 6 hectares. The
facility is capable of producing stainless or carbon steel tubing in various grades, sizes and wall thickness.

North America
Sales to customers in North America accounted for 61% of our sales of tubular products and services in 2022, compared
to 54% in 2021 and 44% in 2020.
We have significant sales and production facilities in each of the United States, Canada and Mexico, where we provide
customers with an integrated product and service offering based on local production capabilities supported by our
global industrial system. In the past few years, we have extended our integrated product and service model, which we
call Rig Direct®, throughout North America, and we operate a seamless pipe mill at Bay City, Texas, which is strategically
located to serve the Eagle Ford and Permian regions. On January 2, 2020, we acquired IPSCO, a U.S. seamless and
welded pipe producer, which has further strengthened our local production capabilities and capacity to provide Rig
Direct® services in the United States. Under Rig Direct®, we manage the whole supply chain from the mill to the rig for
customers under long-term agreements, integrating mill production with customer drilling programs, reducing overall
inventory levels and simplifying operational processes. We first introduced the Rig Direct® model to Pemex in Mexico in
1994, and since then we have supplied them with pipes on a just-in-time basis. Today, we supply a large majority of our
U.S. and Canadian customers for OCTG products with Rig Direct® services.
Sales to our oil and gas customers in the United States and Canada are highly sensitive to oil prices and regional natural
gas prices. Over the past fifteen years, the drilling of productive shale gas and tight oil reserves, made possible by new
drilling technology, has transformed drilling activity and oil and gas production in the United States and Canada.
Following 25 years of declining production, U.S. crude oil production began to increase in 2009 and rose significantly,
from 5.6 million b/d in 2011 to 12.3 million b/d in 2019. Due to the COVID-19 pandemic and collapse in oil prices,
production in 2020 and 2021 fell back to 11.3 million b/d on average but ended 2022 at 12.2 million b/d. Production of
natural gas liquids (“NGLs”) also increased significantly in the past decade in North America. This rapid increase in
production, however, contributed to an excess of supply in the global oil market in 2014 and a consequent fall in the
price of oil. Further rapid increases in production in 2018 and 2019 led to OPEC member country producers and other
producers agreeing to cut production to balance the market and support oil prices. In 2020, however, the impact of the
COVID-19 pandemic led to a sudden and substantial reduction in global oil demand in the first half of 2020 and a
collapse in oil prices. Global oil demand and prices have now effectively recovered, along with economic activity, as
COVID-19 vaccination programs have been rolled out, and OPEC and other producer countries, including Russia,
implemented production cuts to lower supply below demand and reduce inventory levels. At the same time, U.S. shale
producers have restrained investments in response to the post COVID-19 recovery of oil prices as they face financial
market pressures to increase returns to shareholders and limit investments in production growth.
Similarly, natural gas production has risen rapidly over the past decade and the United States became a net exporter of
natural gas for the first time in 2017 and has now become a significant exporter of liquefied natural gas (“LNG”) to
global markets. In Canada, there has been a similar shift towards drilling of shale gas and tight oil reserves.
The drop in oil prices with the onset of the COVID-19 pandemic in the first half of 2020 resulted in a collapse in U.S.
drilling activity, with the number of active rigs falling to the lowest level recorded in over 40 years. However, since then,
there has been a steady recovery in U.S. drilling activity through 2021 and 2022 with the number of active rigs
plateauing below pre-pandemic levels at the end of 2022. As we enter into 2023, drilling activity is showing a slight
decline as North American natural gas prices have declined to low levels due to increasing production and a low level of
demand in the winter heating season.

The level of drilling activity in North America, and consequently demand for our products and services, could also be
affected by actions taken by the governments of the region to accelerate the energy transition by reducing demand for
oil and gas and restricting drilling activity.
During 2020, demand for, and sales of, our OCTG products in the U.S. and Canada collapsed along with drilling activity.
As a result we closed down many of our facilities in the U.S. and, we dismantled our Prudential welded pipe mill in
Calgary, Canada and we integrated welded pipe production at our seamless pipe mill in Sault Ste. Marie, Ontario.
Towards the end of 2020, demand for and sales of OCTG in the U.S. and Canada began a recovery which continued
throughout 2021 and 2022. During this recovery period we reopened many of the facilities we had shut down in 2020
and brought production at our Bay City mill to full capacity. A particular feature of this recovery was the exceptional
price levels for hot rolled coil in the North American market which made the production of welded pipes uneconomic
throughout 2021 and delayed the restart of U.S. welded pipe production into 2022. The ramp up of production capacity
in the United States was further affected by difficulties in hiring qualified workforce in the post-COVID economy.
During 2018, the U.S. government introduced Section 232 tariffs and quotas on the imports of steel products, including
steel pipes, with the objective of strengthening domestic production capacity utilization and investment. The
proportion of the OCTG market supplied by imports initially declined from around 60% prior to the imposition of tariffs
and quotas to around 40% at the end of 2018 but OCTG imports subsequently rose to around 50% in the last two years.
On October 27, 2021, the DOC initiated antidumping duty investigations on OCTG imports from Argentina, Mexico, and
Russia and countervailing duty investigations of OCTG from Russia and South Korea. On October 26, 2022, the ITC
issued a final determination that the imports under investigation caused injury to the U.S. OCTG industry. As a result of
the investigation, Tenaris is required to pay antidumping duties (at a rate of 78.30% for imports from Argentina and
44.93% for imports from Mexico) on its imports of OCTG from Argentina and Mexico for five years. Tenaris has been
paying antidumping duty deposits since May 11, 2022, reflecting the amount of such deposits in its production costs.
The deposit rates will be reset periodically based on the results of the administrative review process. Tenaris has
appealed the duty ruling in respect of imports from Mexico and Argentina. This ruling could limit our sales in the
country.
Our sales in the United States are also affected by the level of investment of oil and gas companies in exploration and
production in offshore projects. The blow-out at the Macondo well in the Gulf of Mexico and the subsequent spillage of
substantial quantities of oil resulted in a moratorium that halted drilling activity. The drilling moratorium was lifted in
October 2010, when new regulations affecting offshore exploration and development activities were announced. Since
then, drilling activity recovered but, in addition to oil price movements, could be affected by actions taken by the
government to restrict drilling activity on Federal lands, which include the Gulf of Mexico.
Oil and gas drilling in Canada is subject to strong seasonality, with the peak drilling season in Western Canada being
during the winter months when the ground is frozen. During the spring, as the ice melts, drilling activity is severely
restricted by the difficulty of moving equipment in muddy terrain.
On June 30, 2021, Canada initiated an antidumping investigation on OCTG from Mexico. A full investigation was
conducted and on January 26, 2022, the Canadian International Trade Tribunal found that Mexican imports were not
injuring the Canadian OCTG industry, and closed the inquiry without imposing any duties.
In Mexico, we have enjoyed a long and mutually beneficial relationship with Pemex, the Mexican state-owned oil
company, and one of the world’s largest crude oil and condensates producers. In 1994, we began supplying Pemex with
Rig Direct® services. At the end of 2022, we renewed our long-term agreement with Pemex for an additional three-year
period.
At the end of 2013, Mexico reformed its constitution to allow increased private and foreign investment in the energy
industry. Pursuant to these reforms, foreign and private investors are allowed to participate in profit and production
sharing contracts and licenses, and Pemex has been transformed into a state-owned production company, but ceased
having a monopoly on production. In addition, a regulatory framework was developed and contracts with foreign and
private investors were awarded. More recently, the government has taken steps to strengthen the role and primacy of
Pemex in oil and gas production in the country as well as that of the state-owned CFE in the provision of electric energy
and unsuccessfully attempted to introduce a constitutional reform proposal of the electricity sector, seeking to reverse
the legal framework derived from the 2013 constitutional energy reform that opened the sector to private investment.
For more information on the proposed reform to the energy market in Mexico, see “Key Information Risk Factors

Risks Relating to Our Business and Industry Adverse economic or political conditions in the countries where we
operate or sell our products and services may decrease our sales or disrupt our manufacturing operations, thereby
adversely affecting our revenues, profitability and financial condition”.
Drilling activity in Mexico and demand for our OCTG products dropped only slightly in 2020 as the country was
protected from lower oil prices by a price hedging program. Over the past two years, drilling activity in Mexico has
increased moderately as the Mexican government and Pemex implemented measures to reverse production decline
while investments pursuant to the energy reform process have been implemented cautiously.
South America
Sales to customers in South America accounted for 20% of our sales of tubular products and services in 2022, compared
to 18% in 2021 and 14% in 2020.
Our largest market in South America is Argentina. We also have significant sales in Brazil and Colombia. We have
manufacturing subsidiaries in each of these countries.
Our sales in South America are sensitive to the international price of oil and its impact on the drilling activity of
participants in the oil and gas sectors, as well as to general economic conditions in these countries. In addition, sales in
Argentina, as well as export sales from our manufacturing facilities in Argentina, are affected by governmental actions
and policies, such as the taxation of oil and gas exports, measures affecting gas prices in the domestic market and other
matters affecting the investment climate. Sales in Brazil are also affected by governmental actions and policies and
their consequences, such as measures relating to the taxation and ownership of oil and gas production activities and
the operations of Petrobras. For more information, please see “Key Information Risk Factors Risks Relating to Our
Business and Industry Adverse economic or political conditions in the countries where we operate or sell our products
and services may decrease our sales or disrupt our manufacturing operations, thereby adversely affecting our revenues,
profitability and financial condition”.
A principal component of our marketing strategy in South American markets is the establishment of long-term supply
agreements and Rig Direct® services with national and international oil and gas companies operating in those markets.
In Argentina, we have a significant share of the market for OCTG products. We have longstanding business relationships
with YPF S.A. (“YPF”), the Argentine state-controlled company, and with other operators in the oil and gas sector. We
strengthened our relationship with YPF in 2013 through a long-term agreement, which was renewed for an additional
five-year term at the beginning of 2022, under which we provide Rig Direct® services with the objective of reducing
YPF’s operational costs as it aims to increase production through investments in Argentina’s shale oil and gas reserves.
Drilling activity fell significantly during 2019 after the electoral process in Argentina. In 2020, our sales were affected by
ongoing uncertainties regarding the energy policies that would be adopted by the incoming government as well as the
onset of the COVID-19 pandemic. Activity recovered during 2021 and 2022. The principal restraint on further increases
in activity, particularly in the Vaca Muerta shale play, is the lack of pipeline capacity for exporting oil and for
transporting gas to the main consumption centers in Buenos Aires. New pipeline infrastructure is being installed;
construction of the first phase of a new gas pipeline and two oil export pipelines started in 2022 and further pipeline
infrastructure is expected for the next two to three years. We have reactivated our welded pipe mill in Valentin Alsina,
province of Buenos Aires, to supply pipes for these pipelines under construction and are supplementing deliveries with
welded pipes from our mill in Brazil.
In Brazil, we have a longstanding business relationship with Petrobras. We supply Petrobras with casing (including
premium connections) and line pipe products, many of which are produced in our Brazilian welded pipe facility, for
both offshore and onshore applications. More recently, we have increased the sale of imported seamless products to
Petrobras for offshore use, including the supply of seamless casing with premium connections, accessories and Rig
Direct® services for use in the pre-salt area and seamless line pipe for use in offshore risers. With the development of
Brazil’s deepwater pre-salt complex, our mix of products sold in Brazil has evolved from one including mainly line pipe
for onshore pipeline projects to one which includes large diameter conductor and surface casing, intermediate and
production casing and line pipe for use in deepwater applications. In 2020, with the onset of the COVID-19 pandemic
and the collapse in oil prices, Petrobras reduced its onshore drilling operations to focus on pre-salt offshore
developments. In 2022, offshore drilling activity began to increase as a result of the development of the Buzios and
other pre-salt fields by Petrobras as well as other investments by major oil companies. Consumption of OCTG products
in Brazil has remained at a relatively low level over the past five years, as Petrobras reduced its investments in response
to budgetary constraints, concentrating on developing its most productive reserves in the pre-salt fields, but OCTG

consumption is expected to pick up in 2023. Demand for line pipe for pipeline projects also declined to very low levels
with only one major project implemented in the past seven years, but line pipe demand is also expected to pick up in
the next years. In response to market-opening measures and the attractiveness of the deepwater reserves, major oil
companies are increasing their investments in Brazil, while Petrobras is focusing investments in world class assets in
deepwater.
In Colombia, we have established a leading position in the market for OCTG products since 2006, following our
acquisition of TuboCaribe, a welded pipe manufacturing facility located in Cartagena. Although the market was deeply
affected by low oil prices between 2014 and 2016, it has grown over the past decade as the country encouraged
investment in its hydrocarbon industry and opened its national oil company to private investment. In 2020, the
pandemic-related collapse in oil prices resulted in a drop of drilling activity which recovered in 2021 and 2022. Recently,
however, drilling activity is being affected as the new government has introduced policies aimed at reducing
exploration activity while local protests and security concerns are increasing at some drilling locations. Our principal
customer in Colombia is Ecopetrol S.A. (“Ecopetrol”), to which we supply Rig Direct® services. In 2022 we renewed our
agreement with Ecopetrol for two years.
In Guyana and neighboring Suriname, offshore drilling activity has been increasing rapidly over the past three years
following the discovery of large, cost competitive oil reserves. We are supplying casing for many of the exploration
wells and, at the end of 2021, we were awarded a 10-year contract to supply large and medium diameter casing
with Rig Direct®-alike services to the deepwater offshore development projects in the Starbroek block.
We also have sales in Ecuador, supplying Petroamazonas Ecuador S.A., which merged with EP PetroEcuador, the
national oil company, as well as private operators. To increase local content, we have established a local OCTG
threading facility in Machachi.
We were present in the Venezuelan OCTG market for many years and we maintained business relationships with
Petróleos de Venezuela S.A. and the joint venture operators in the oil and gas sector until the imposition of economic
sanctions by the Office of Foreign Assets Control (“OFAC”). Additionally, we maintained business relationships with
Chevron in Venezuela until April 22, 2020, when their sanctions license expired. Our sales in Venezuela declined to low
levels in 2020, with no sales in 2021 and 2022. Recently, Chevron has been authorized to resume certain operations,
which could lead to a resumption of sales in Venezuela in the future.
Europe
Sales to customers in Europe accounted for 8% of our sales of tubular products and services in 2022, compared to 10%
in 2021 and 12% in 2020.
Our single largest country market in Europe is Italy. The market for steel pipes in Italy (as in much of the European
Union) is affected by general industrial production trends, especially in the mechanical and automotive industry, and by
investment in power generation, petrochemical and oil refining facilities. Sales to the mechanical and automotive
industries and for HPI and power generation projects in Italy and the rest of Europe in 2020 were affected by lower
prices reflecting increased competitive pressures, but volumes were relatively stable. In 2021, activity and our sales
increased, while in 2022, although activity was affected by the Russian invasion, our sales increased as prices rose to
compensate higher costs.
In Europe we also have significant sales to the oil and gas sector, particularly in the North Sea. Demand from this
market is affected by oil and gas prices in the international markets and their consequent impact on oil and gas drilling
activities in the North Sea and other areas, like Romania. In addition, we ceased sales to Russia that would breach
applicable sanctions imposed by the U.S. and the EU following the Russian invasion of Ukraine.
Europe is also a region which we expect will be at the forefront of developments in low-carbon energy, including
hydrogen storage and transportation, carbon capture and sequestration and waste-to-energy power generation. We
are participating in these market segments where we expect to see growth in sales in the coming years.

Middle East and Africa
Sales to customers in the Middle East and Africa accounted for 9% of our sales of tubular products and services in 2022,
compared to 14% in 2021 and 25% in 2020.
Our sales in the region remain sensitive to international prices of oil and gas and their impact on drilling activities as
well as to the production policies pursued by OPEC, and, more recently, OPEC+ countries, many of whose members are
located in this region. In the past few years, oil and gas producing countries in the Middle East, led by Saudi Arabia,
have increased investments to develop gas reserves to fuel regional gas-based industrial development, which have
positively affected their consumption of premium OCTG products. Saudi Arabia, in particular, has shown strong growth
in sour and high pressure gas field drilling activity. More recently, the main national oil companies in the Gulf have also
begun to increase investments to add oil and LNG production capacity as they seek to accelerate the monetization of
their oil and gas reserves. Additionally, in the eastern Mediterranean, vast reserves of natural gas have been
discovered, some of which have been targeted for fast track development.
In Africa, international oil companies increased investments in exploration and production in offshore projects in 2012
and 2013 but began to postpone or reduce their investment commitments in 2014 due to the high cost of offshore
project developments and a lower success rate in exploration activity. Since 2015, following the oil price collapse,
exploration activity was cut back and major project commitments were postponed. The effect on demand was
compounded by the high inventory levels held in the region. In 2022, this situation began to change with an increase in
exploration and drilling activity and normalization of OCTG inventory levels.
In the Caspian region, major oil companies operating in Kazakhstan and Azerbaijan increased their investments and
drilling activity following the recovery of oil prices in 2017 and we opened a premium threading facility in Kazakhstan in
2019. In 2020 and 2021, however, our sales were affected by the impact of the COVID-19 pandemic on the operations
of our customers and the impact on drilling activity of adherence to the production cuts agreed by the OPEC+ countries
in response to the collapse of oil demand due to the pandemic. Since then, drilling activity and our sales have remained
at low levels.
In the past few years, uprisings affected drilling activity in countries such as Syria, Libya and Yemen and, in the case of
Libya, the oil and gas industry was effectively shut down in 2011. In addition, in the past years, U.S. and E.U. sanctions
have affected production and exports in Iran.
Our sales in the Middle East and Africa could be adversely affected by political and other events in the region, such as
armed conflicts, terrorist attacks and social unrest, which could materially impact the operations of companies active in
the region’s oil and gas industry. Our sales in the region can also be affected by the levels of inventories held by the
principal national oil companies and their effect on purchasing requirements. For more information, please see “Key
Information Risk Factors Risks Relating to Our Business and Industry Adverse economic or political conditions in
the countries where we operate or sell our products and services may decrease our sales or disrupt our manufacturing
operations, thereby adversely affecting our revenues, profitability and financial condition”.
In 2019 and 2020, sales in the Middle East rose while sales in Africa (including the East Mediterranean) were affected
by the slowdown in drilling activity and investments in deepwater projects. Sales in the region declined in 2021 as a
result of various factors, including the slowdown in investments in drilling activity pursuant to the pandemic and
reduction in oil demand and prices and ongoing inventory reductions at some of the region’s largest consumers like
Saudi Arabia and the United Arab Emirates. In 2022, our sales in the region began to recover and we expect this
recovery will strengthen during 2023.
In January 2019, we acquired 47.8% of SSPC, a listed welded steel pipe producer in Saudi Arabia. SSPC produces OCTG,
line pipe and commercial pipe products mainly for the local market and it is qualified to supply Saudi Aramco for certain
products. Through this investment, Tenaris has increased its local industrial presence in an important oil and gas market
where policies are being implemented to diversify the economy and increase local manufacturing. Saudi Arabia
continues to reinforce measures in favor of local content particularly for suppliers to state-owned companies like Saudi

Graphics
Annual Report 2022
43
Aramco. In 2022, we entered into a long-term agreement with Saudi Aramco for the supply of seamless OCTG products
that prioritizes local production where possible.
In addition, Tenaris currently owns, through its subsidiary SSPC, a 35% share interest in GPC, a Saudi-German joint
venture, established in 2010 and located in Jubail, Saudi Arabia, which manufactures LSAW pipes.
In August 2019 we were awarded a long-term agreement with Rig Direct® conditions, valued at $1.9 billion, to supply
approximately half of the OCTG requirements of Abu Dhabi National Oil Company (“ADNOC”) in Abu Dhabi over the
next five to seven years. In order to serve this market, we have expanded our local service base and are constructing a
new premium OCTG threading facility. We have also been awarded significant contracts to supply Qatargas Liquefied
Gas Company Limited (“QatarGas”) and Kuwait Oil Company (“KOC”) over the coming years.
Asia Pacific
Sales to customers in the Asia Pacific accounted for 2% of our sales of tubular products and services in 2022, compared
to 4% in 2021 and 7% in 2020.
We have a presence in the region with local production facilities in Indonesia, China and a service center in Australia.
Sales to Indonesia and other markets in South East Asia and Oceania are mainly affected by the level of oil and gas
drilling activity, particularly offshore drilling activity. Low oil prices have deeply affected drilling activity and our sales
throughout the region. In addition, the long-term agreement to provide pipes with Rig Direct® services in Thailand was
terminated in 2020, anticipating changes in the ownership of oil and gas development concessions.
Our sales in China are concentrated on premium OCTG products used in oil and gas drilling activities. Over the past
years, China has significantly reduced its imports of OCTG products as local producers compete ferociously in an
oversupplied market. We continue, however, to seek new markets in niche applications and in 2016 we opened a
components facility for processing pipes for use in airbags for automobiles, which we are currently expanding for the
second time. In 2020, we established a joint venture with Baotou Steel, a major domestic supplier of seamless pipes to
the onshore oil and gas fields, for the construction of a premium threading facility located within our partner’s
steelmaking facilities in Inner Mongolia. The new facility, which finishes pipes produced mainly by our joint venture
partner, began production during the first quarter of 2022. Our participation in the joint venture is 60%. During 2022,
Baotou Steel and Baosteel International Group (“Baosteel”) merged their seamless pipe business into a new company
named Baogang. Baogang now holds 40% of the shares in the joint venture with Tenaris, and has recently confirmed its
intention to continue with the joint venture.
In Japan, our subsidiary, NKKTubes, competed against other domestic producers. In November 2022 we entered into a
definitive wrap-up agreement with JFE to terminate our joint venture and cease NKKTubes’ operations. The market for
steel pipe products in Japan is mostly industrial and depends on general factors affecting domestic investment,
including production activity. With the closure of NKKTubes in June 2022, we have largely ceased to serve this market
and accordingly, our sales in the Asia Pacific region now represent a very low proportion of sales in our Tubes segment.
Thus, starting on January 1, 2023, we will report our sales in this region together with sales in the Middle East and
Africa.
Others
Our other products and services currently include sucker rods used in oil extraction activities, oil and gas services,
including fracking and coiled tubing services in Argentina, sales of pipe for plumbing applications from our Italian
Piombino mill, coiled tubes used in oil and gas extraction activities, and sales of raw materials and energy that exceed

our internal requirements. Net sales of other products and services amounted to 5% of total net sales in 2022,
compared to 8% in 2021 and 6% in 2020.
During 2022, we closed down our Brazilian industrial equipment business and, in 2021, we sold our Geneva mill (pipes
for construction activities) in the United States as well as a small Saudi equipment manufacturing and erection business
that we acquired during our SSPC acquisition.

The global market for steel pipe products is highly competitive. Seamless steel pipe products, which are used
extensively in the energy industry particularly for offshore, high pressure, high stress, corrosive and other complex
applications, are produced in specialized mills using round steel billets and specially produced ingots. Welded steel pipe
products are produced in mills which process steel coils and plates into steel pipes. Steel companies that manufacture
steel coils and other steel products but do not operate specialized seamless steel mills are generally not competitors in
the market for seamless steel pipe products, although they often produce welded steel pipes or sell steel coils and
plates used to produce welded steel pipes.
The production of steel pipe products following the stringent requirements of major oil and gas companies operating in
offshore and other complex operations requires the development of specific skills and significant investments in
manufacturing facilities. By contrast, steel pipe products for standard applications can be produced in most seamless
pipe mills worldwide and sometimes compete with welded pipe products for such applications including OCTG
applications. Welded pipe, however, is not generally considered a satisfactory substitute for seamless steel pipe in high-
pressure or high-stress applications.
Over the past two decades, substantial investments have been made, especially in China but also in other regions
around the world, to increase production capacity of seamless steel pipe products. Production capacity for more
specialized product grades has also increased. With the downturn between 2014 and 2016 in the price of oil and
demand for tubes for oil and gas drilling, the overcapacity in steel pipe and seamless steel pipe production worldwide
became acute, extending beyond commodity grades. This situation has been accentuated by the more recent COVID-19
induced collapse in demand and the prospect of an accelerated energy transition. Effective competitive differentiation
and industry capacity closures will be key factors for Tenaris.
Our principal competitors in steel pipe markets worldwide are described below.
Vallourec S.A. (“Vallourec”), a French company, has mills in Brazil, China, Germany and the United States.
Vallourec has a strong presence in the European market for seamless pipes for industrial use and a significant
market share in the international market with customers primarily in Europe, the United States, Brazil, China, the
Middle East and Africa. Vallourec is an important competitor in the international OCTG market, particularly for
high-value premium joint products, where it operates a technology partnership for VAM
®
premium connections
with Nippon Steel Corporation (“NSC”). Prior to the collapse in oil prices in 2014 to 2016, Vallourec increased its
production capacity by building mills in Brazil (jointly with NSC) and Youngstown, Ohio, acquiring three tubular
businesses in the United States and Saudi Arabia, and concluding an agreement with a Chinese seamless steel
producer, Tianda Oil Pipe Company (“Tianda”) to distribute products from Tianda in markets outside China. In
early 2016, in response to accumulating losses, Vallourec announced a $1 billion capital increase, more than half
of which was provided by a French government fund and NSC, who each agreed to increase their equity
participation to 15%. At the same time, an industrial restructuring program was announced under which
Vallourec reduced capacity in Europe, closing its rolling mills in France, combined its operations in Brazil with
that of the new mill held with NSC, acquired a majority position in Tianda and bought out the remaining minority
interest, and strengthened its cooperation with NSC for the development and testing of premium connection
products and technology. Despite this restructuring program, Vallourec’s losses continued and its equity position
turned negative. In June 2021, Vallourec completed a further financial restructuring, in which its former
shareholders, including NSC and Bpifrance, a French state-owned investment company, were severely diluted
and its creditors, including private equity investors, assumed effective control. Under this restructuring, NSC
exited its investment in the Brazilian mill and had its position in Vallourec diluted to around 3%. Subsequently,
NSC also sold its equity interests in Vallourec’s U.S. operations. In 2022, Vallourec confirmed that it would close
its German mills during 2023 and would invest EUR100 million in its Brazilian mills to enable the transfer of its
specialized products for oil and gas customers from Germany to Brazil.
Japanese players NSC and, to a lesser extent, JFE together enjoy a significant share of the international market,
having established strong positions in markets in the Far East and the Middle East. They are internationally

recognized for their supply of high-alloy grade pipe products. In recent years, NSC increased its capacity to serve
international markets through the construction with Vallourec of a new seamless pipe mill in Brazil, and further
strengthened its ties with Vallourec through participating in Vallourec’s 2016 capital increase and combining
their respective Brazilian operations. As part of the latest financial restructuring of Vallourec, NSC relinquished
its participation in the Brazilian operation and ceded its reference shareholder position in Vallourec. In 2022,
NSC, as part of a general restructuring of its steelmaking operations, closed one of its three seamless pipe
production mills and announced that it would close its large diameter welded pipe mill and exit the large
diameter welded line pipe market.
In recent years, TMK, a Russian company, led the consolidation of the Russian steel pipe industry, invested to
modernize and expand its production capacity in Russia and expanded internationally through acquisitions into
Eastern Europe and the United States. TMK also expanded in the Middle East through the acquisition of a
controlling interest in Gulf International Pipe Industry LLC (“Gulf International Pipe”), a welded pipe producer in
Oman. More recently, however, TMK adopted a strategy of monetizing its international assets by reducing its
participation in Gulf International Pipe and selling IPSCO to Tenaris, as well as strengthening its position in its
domestic market by acquiring Chelpipe, the second Russian producer of seamless pipes in 2021. In 2022,
following the Russian invasion of Ukraine, the American Petroleum Institute (API) withdrew its license for
products produced in TMK’s mills in Russia. Russian producers or their controlling shareholders are now subject
to U.S., EU and UK sanctions, among others, and are now largely prevented from competing in several markets.
Over the past two decades, Chinese producers increased production capacity substantially and strongly
increased their exports of steel pipe products around the world. Due to unfair trading practices, many countries,
including the United States, the European Union, Canada, Mexico and Colombia, have imposed anti-dumping
restrictions on Chinese imports to those regions. In 2009, the largest Chinese producer of seamless steel pipes,
Tianjin Pipe (Group) Corporation Limited (“TPCO”), announced a plan to build a new seamless pipe facility in the
United States in Corpus Christi, Texas; heat treatment and pipe finishing facilities have been constructed but
steelmaking and hot rolling facilities have not been completed. As part of a financial restructuring, a 51%
shareholding in TPCO was sold to Shanghai Electric Group and has now been sold on to Citic Group Corporation
Ltd. (“Citic”), a state-owned conglomerate. Although producers from China compete primarily in the
“commodity” sector of the market, several of these producers, including Baosteel and TPCO, have developed
and are selling more sophisticated products, particularly in the domestic market.
The tubes and pipes business in the United States and Canada has experienced significant consolidation over the
years, while new players have also emerged. In recent years, Tenaris constructed a greenfield seamless pipe mill
at Bay City, Texas and acquired IPSCO from TMK in January 2020, becoming the leading seamless pipe producer
in the United States, while U.S. Steel integrated its seamless pipe business by building an EAF steel shop in
Fairfield, Alabama, which started up in late 2020. At the same time, many new players have built, or announced
plans to build, pipe mills in the United States. These include, in addition to TPCO, Boomerang LLC, a company
formed by a former Maverick executive that opened a welded pipe mill in Liberty, Texas, in 2010, now known as
PTC Liberty Tubulars and part of the PTC Alliance; Benteler, a European seamless pipe producer that built a new
seamless pipe mill in Louisiana, which opened in September 2015; and a plethora of welded pipe mills
established by subsidiaries of foreign pipe producers, such as SeAH Steel (“SeAH”), of Korea and JSW Group
(“JSW”), of India. North American pipe producers are largely focused on supplying the U.S. and Canadian
markets, where they have their production facilities. In Canada, Tenaris closed its Prudential welded pipe mill in
Calgary in 2020 and integrated a welded pipe production line at its seamless pipe mill in Sault Ste. Marie, Ontario
in 2022.
Korean welded pipe producers, who have a limited domestic market, have targeted the U.S. market for standard
applications. They have gained a significant market position, despite the application of anti-dumping duties for
unfair trading practices and being subject to Section 232 quotas. One of them, SeAH, has acquired and built local
welded pipe production facilities in the United States.
Tubos Reunidos S.A. (“Tubos Reunidos”) of Spain, Benteler of Germany and Voest Alpine A.G. (“Voest Alpine”) of
Austria each have a significant presence in the European market for seamless steel pipes for industrial
applications. Voest Alpine also has a relevant presence in the U.S. and Canadian OCTG markets and some other
international OCTG markets. In 2016, Tubos Reunidos opened an OCTG threading facility targeting international
markets. In 2006, ArcelorMittal S.A. (“ArcelorMittal”) created a tubes division through several acquisitions and
has mills in North America, Eastern Europe, Venezuela, Algeria and South Africa and has built a seamless pipe
mill in Saudi Arabia.

In the Middle East, particularly in Saudi Arabia, which has implemented policies to encourage local production
for its oil and gas industry, several pipe mills were established, including a seamless pipe mill built by Jubail
Energy Services Company (“JESCO”), a company established with majority participation from a state-backed
industrial development company, and a seamless pipe mill originally built by a joint venture of ArcelorMittal and
local shareholders (“AMTJ”). These local players have been strengthening their capabilities and are taking an
increasing share of the pipes supplied to Saudi Aramco as well as exporting to other countries in the Middle East
and the rest of the world. In January 2019, Tenaris acquired a controlling 47.79% participation in SSPC, a local
welded pipe producer. In 2021, JESCO and AMTJ, who were both operating with losses, combined their
operations at the behest of the Saudi Public Investment Fund.
Producers of steel pipe products can maintain strong competitive positions in markets where they have their pipe
manufacturing facilities due to logistical and other advantages that permit them to offer value-added services and
maintain strong relationships with domestic customers, particularly in the oil and gas sectors. Our subsidiaries have
established strong ties with major consumers of steel pipe products in their home markets, reinforced by Rig Direct®
services, as discussed above.
Capital Expenditure Program
During 2022, our capital expenditures, including investments at our plants and information systems (“IT”), amounted to
$378 million, compared to $240 million in 2021 and $193 million in 2020. Of all capital expenditures made during 2022,
$346 million were invested in tangible assets, compared to $214 million in 2021 and $168 million in 2020.
In 2022, we increased investments in alternative energies and focused on consolidating our position in North America,
enhancing efficiency to achieve full capacity in all our Industrial plants and increasing product differentiation.
The major highlights of our capital spending program during 2022 included:
efficiency improvements focused on steel making, heat treatment and hot rolling processes fostering the
integrations in our North American plants, consolidating Tenaris’s position;
productivity improvement and revamping on existing welded lines in Brazil and Argentina to strengthen our
competitiveness in pipes of large outside diameter and local market;
increasing product and service differentiation, reinforcing our production capabilities for our Dopeless
connection products, the increase of capacity on special steel pipes and on automotive components (Qingdao
in China and Tamsa in Mexico), and the acquisition of new equipment for fracturing services;
the revamping and upgrade of our existing lines to improve the standards of industrial efficiency and safety,
including the increase of capacity in the coupling mills (Tamsa in Mexico, Siderca in Argentina and Tubos del
Caribe in Colombia), and our HSE continuous improvement program (including the ongoing overhead cranes
replacement);
the ongoing construction of a wind farm in Argentina and initial actions in other countries to achieve the target
of reducing carbon emissions intensity by 30% by 2030 compared to a 2018 baseline; and
offices redesign project aligning our workspace to the new way of working.
Investments in information systems and other intangible assets totaled $32 million in 2022, compared to $26 million in
2021 and $26 million in 2020.
The focus of our IT capital-spending program has been set on four drivers:
digital integration/services to customers and logistics, synergizing with current favorable market conditions;
update and standardization of our manufacturing systems, especially in our North American multi-plant
industrial system;
risk mitigation, operational continuity and cybersecurity; and
process simplification and efficiency.

Graphics
Annual Report 2022
47
We continue carrying out our multi-year programs: the Integrated Scheduling System in Tamsa, Dalmine and Silcotub,
industrial cybersecurity and infrastructure, and the Industrial Cost System. These investments will enable Tenaris to be
faster and more flexible in the current market context and to sustain its industrial excellence.
Capital expenditures are expected to increase to around $650 million in 2023, mainly due to projects that are expected
to contribute to our 2030 target for reducing the carbon emission intensity of our operations. In addition to our
ongoing investment in a wind farm in Argentina, we will make investments that are expected to improve energy
efficiency in Italy, Romania and Argentina, among others.
Additionally, the investment program for 2023 includes:
the increase of productivity, safety and CO
2
reduction in several Tenaris facilities, in particular the replacement
of Siderca’s electric arc furnace number 4 by a Consteel® electromagnetic stirring furnace;
the revamping of the current exhaust fumes system in the Koppel Steel Shop in the United States;
the replacement of the austenitizing furnace (Nassheuer furnace) in Dalmine, Italy with a new gas furnace,
aiming at increasing heat treatment capacity, productivity and product feasibility range, and reducing
transformation costs and CO
2
emissions;
the construction of new threading facilities, including a swaging line and offices in Abu Dhabi;
the completion of the Dopeless® migration to the 3.x plan; and
the offices redesign project aligning our workspace to the new way of working (after finishing the pilot
projects, the first stage of the program covers the renovation of 12 offices used by more than 650 people in
Mexico, the U.S., Argentina, the UK, Canada and Abu Dhabi).
Raw Materials and Energy
The majority of our seamless steel pipe products are manufactured in integrated steelmaking operations using the
electric arc furnace route, with the principal raw materials being steel scrap, DRI, HBI, pig iron and ferroalloys. In
Argentina we produce our own DRI from iron ore using natural gas as a reductant. Our integrated steelmaking
operations consume significant quantities of electric energy, purchased from the local market, and in part produced by
our thermo-electric power generating plant. Our welded steel pipe products are processed from purchased steel coils
and plates.
The weight of the different steelmaking raw materials and steel vary with the proportion of seamless and welded pipes
in the total production mix and among the different production facilities in our industrial system, as well as the
specifications of the final products and other factors. On average, in 2022, steel scrap, pig iron, HBI and DRI represented
approximately 30% of our steel pipe products’ costs, while purchased steel in the form of billets or coils represented
approximately 14%, with direct energy accounting for approximately 6%.
The above raw material inputs are subject to price volatility caused by supply, political and economic situations,
financial variables and other unpredictable factors. For further information on price volatility, see “Key Information
Risk Factors Risks Relating to Our Business and Industry Increases in the cost of raw materials, energy and other
costs, limitations or disruptions to the supply of raw materials and energy, and price mismatches between raw
materials and our products may hurt our profitability”. The costs of steelmaking raw materials and of steel coils and
plates, increased on average in 2021 compared to 2020 and were subject to high levels of volatility during 2022 as they
were affected by the Russian-Ukraine armed conflict and the sanctions being imposed on Russian individuals,
companies and institutions. For more information see “Key Information – Risk Factors Risks Relating to Our Business
and Industry The Russia-Ukraine armed conflict may adversely affect our operations”.
Steel scrap, pig iron and HBI
Steel scrap, pig iron and HBI for our steelmaking operations are sourced from local, regional and international suppliers.
In Argentina we produce our own DRI and source ferrous scrap domestically through a wholly owned scrap collecting
and processing subsidiary. In Italy we purchase pig iron and ferrous scrap from local and regional markets. In Mexico we
import our pig iron and HBI requirements and purchase scrap from domestic and international markets. In Romania we

Graphics
Annual Report 2022
48
source ferrous scrap mainly from the domestic market and we import pig iron. In the United States, we source scrap
from the local market to supply our steelmaking facility, and also source pig iron from international markets.
International prices for steel scrap, pig iron and HBI can vary substantially in accordance with supply and demand
conditions.
Annual scrap prices decreased slightly in 2022, but remained at very high levels compared to historical averages. As a
reference, prices for Scrap Shredded U.S. East Coast, published by Platts, averaged $429 per ton in 2022 and $441 per
ton in 2021, while it averaged $260 per ton in 2020. Scrap prices spiked as a consequence of the Russian invasion of
Ukraine due to the relevance of both countries as exporters of semi-finished steel and pig iron. In 2022, Brazil became
the largest pig iron supplier to the United States as supply from Russia and Ukraine decreased significantly. As the
global economy growth began to decelerate, prices decreased during the second half of 2022.
Iron ore
We consume iron ore in the form of pellets for production of DRI in Argentina. Siderca’s consumption of iron ore during
2022 was approximately 972 thousand tons, supplied by Vale International S.A. and Samarco Mineração S.A. from
Brazil, and Iron Ore Company (“IOC”) from Canada. Annual iron ore prices dropped during 2022 in comparison to 2021,
but remained at very high levels compared to historical averages. As a reference, prices for IODEX 62% Fe Index,
published by Platts, averaged $120 per ton in 2022 and $160 per ton in 2021, in comparison to $108 in 2020. In January
2022, 62% Fe Iron ore prices, published by Platts, averaged $131 per ton. Supported by a recovery in global steel
production, prices reached an average of $151 per ton in March 2022. However, due to a contraction in China's steel
production during the second half of the year and a decline in global steel demand, prices fell to values below $100 per
ton. Since November 2022, prices of iron ore have recovered on expectations of a rebound in steel production and
demand in 2023, returning to levels of around $123 per ton. The DRI pellet market started with a supply squeeze in
2022 as Ukrainian exports were affected by the conflict and India imposed heavy export tariffs. Since mid-year, the
market suffered from weak demand mainly by European and Asian purchasers. Pellet premiums averaged $72 per ton
in 2022, around 20% above 2021 levels. Prices are expected to decrease in 2023 as India has now removed the export
tariffs, and demand from Europe could remain weak at least until the second quarter of 2023.
Round steel bars
We mainly satisfy our steel bars and ingots requirements with materials produced in our steelmaking facilities in
Argentina, Italy, Mexico, Romania and the United States. We complement this internal supply with purchases of steel
bars and ingots from third parties as required, and particularly for use in our seamless steel pipe facilities in Canada and
the United States and to supplement production from our steel shop in Mexico.
In Canada, we mainly source our steel bars requirements from our integrated facilities in Argentina, Italy, Mexico,
Romania and United States.
In Mexico, we source additional steel bars from Ternium’s Mexican facilities under a one-year agreement ending in
April 2023, renewable for an additional year. Currently, the Company is assessing alternatives for sourcing these
materials, including a renegotiation of the contract with Ternium.
In the United States, following the acquisition of IPSCO in 2020, we own a steel shop facility in Koppel, Pennsylvania.
After having completed certain investments in 2021, this facility provides part of the steel bars required by our Bay City
and Ambridge mills. We also use steel bars produced in our integrated facilities in Romania, Italy and Mexico. These
imports have been granted an exclusion from Section 232 tariffs, and we have recently received a one year exclusion
for the import of steel bars from Argentina. Additionally, we have a contract in place with Nucor Steel to purchase a
portion of the steel bar requirements in our Bay City mill.
In Japan, following the termination of our joint venture and the closure of the NKKTubes plant, JFE agreed to provide us
with 13 Chrome alloy products for two years, while we advance with the investments required to produce such
materials in the rest of our industrial system. For further information on the termination of the NKKTubes joint venture,
please refer to note 35 “Other relevant information - Agreement to terminate NKKTubes joint venture” of our audited
consolidated financial statements included in this annual report.

Steel coils and plates
For the production of welded steel pipe products, we purchase steel coils and steel plates principally from domestic
producers for processing into welded steel pipes. We have welded pipe operations in Argentina, Brazil, Canada,
Colombia, Saudi Arabia and the United States.
After reaching all-time highs in 2021, the steel coil market prices in 2022 decreased 35%. As a reference, prices for hot
rolled coils, HRC Midwest USA Mill, published by CRU, averaged $1,128 per metric ton in 2022 and $1,734 per metric
ton in 2021.
For our welded pipe operations in the United States, a significant part of our requirements for steel coils are supplied
by Nucor Steel which is our principal supplier in the United States. Nucor Steel has a steel coil manufacturing facility in
Hickman, Arkansas, near to our principal welded pipe facility in the United States. To secure a supply of steel coils for
our U.S. facilities, during 2022 we renewed a long-term purchase agreement with Nucor Steel which is due to expire at
the end of 2024. During 2022, we also diversified the sourcing of these materials to include Ternium and Big River Steel.
In Canada, we have restarted negotiations with the main local suppliers to reach long-term agreements for our welded
pipe operations. Among such suppliers are ArcelorMittal Dofasco, which has steel coil manufacturing facilities in
Hamilton, Ontario, and Algoma Steel, which has steel coil manufacturing facilities in Sault Ste. Marie, Ontario.
We also purchase steel coils and plates for our welded pipe operations in South America (Colombia, Brazil and
Argentina) principally from Usiminas, Gerdau S.A. and ArcelorMittal Tubarão in Brazil, from Ternium Argentina S.A.
(“Ternium Argentina”), a subsidiary of Ternium in Argentina, and from Ternium’s facilities in Mexico. In addition, in
Brazil we also source plates and coils from international suppliers when not produced domestically. In Saudi Arabia, we
mainly purchase steel coils and plates from the local market.
Energy
We consume substantial quantities of electric energy, mainly at our electric steel shops in Argentina, Italy, Mexico,
Romania and the United States.
In Argentina, our local electric energy requirements are satisfied through purchases in the local market and by a 35-
megawatt thermo-electric power generating plant located within the Campana facility. In Dalmine, Italy, we have a 120-
megawatt power generation facility which is designed to have sufficient capacity to meet most of the electric power
requirements of the operations. The additional energy needed to cover the peaks of consumption and the excess
energy produced are purchased and sold to the market while heat is sold for district heating. In Mexico, our electric
power requirements are mainly satisfied by Techgen, a natural gas-fired combined cycle electric power plant in the
Pesquería area of the State of Nuevo León, while a small portion of our energy requirements are furnished by the
Mexican government-owned CFE. In the last few years, the Mexican government made various attempts to modify
rules and regulations governing the energy market in Mexico with potential impact on the energy supply and its cost.
For more information see “Key Information Risk Factors Risks Relating to Our Business and Industry Adverse
economic or political conditions in the countries where we operate or sell our products and services may decrease our
sales or disrupt our manufacturing operations, thereby adversely affecting our revenues, profitability and financial
condition”. In Romania and the United States, we source electric energy from the local market.
We consume substantial volumes of natural gas in Argentina, for the generation of DRI in addition to the requirements
for producing seamless pipes. Tecpetrol, a San Faustin subsidiary, is our main natural gas supplier in Argentina under
market conditions and according to local regulations.
We have transportation capacity agreements with Transportadora de Gas del Norte S.A. (“TGN”), a company in which
San Faustin holds a significant but non-controlling interest, corresponding to capacity of 1,000,000 cubic meters per day
until April 2027. In order to meet our transportation requirements for natural gas above volumes contracted with TGN,
we also have agreements with Naturgy S.A. (“Naturgy”), for a maximum transportation capacity corresponding to
approximately 970,000 cubic meters per day. For the final transportation phase, we also have a supply contract with
Naturgy. Both contracts with Naturgy are in place until April 2023 and are expected to be renewed.
In addition to the amount of gas consumed at our Italian plants, we also require a substantial volume of natural gas to
feed our power generation facility in Italy. Our natural gas requirements for the power generation facility are currently
supplied by Edison Energia S.p.A while the natural gas consumed at our Italian plants is supplied by Eni S.p.A.

Our costs for electric energy and natural gas vary from country to country. Prior to late 2021, energy costs remained
generally flat due to the increasing availability of natural gas from shale plays and additional renewable energy
generation at more competitive prices. In a context of uncertainty regarding future energy prices, in December 2020,
the Argentine government launched a new gas plan to increase natural gas supply following a drop from the maximum
levels reached in 2019. Because winter demand for natural gas continues to outpace supply, Argentina is required to
import natural gas from Bolivia, Chile and LNG from the international market at high prices, in addition to using liquid
fuel to generate electricity. In an international context of higher gas prices and reduced availability, Argentina may be
exposed to restrictions in winter, which would affect our operations. In late 2021 energy and gas prices increased,
particularly in Europe. The Russian invasion of Ukraine led to renewed volatility in energy commodity prices,
accelerated by the low level of inventories throughout the first half 2022, reaching a peak in late August and then
slowly stabilizing at high levels. In early 2023, European electricity prices fell to pre-war levels, thanks to lower gas
prices, mainly due to a particularly mild winter. Due to milder temperatures, a decrease in demand for gas and the
activation of alternative energy, the filling of gas storage facilities in the EU countries remains high. See “Key
Information Risk Factors Risks Relating to Our Business and Industry Increases in the cost of raw materials, energy
and other costs, limitations or disruptions to the supply of raw materials and energy; and price mismatches between
raw materials and our products may hurt our profitability”, “Key Information – Risk Factors Risks Relating to Our
Business and Industry Adverse economic or political conditions in the countries where we operate or sell our products
and services may decrease our sales or disrupt our manufacturing operations, thereby adversely affecting our revenues,
profitability and financial condition, and for more information on the impact on our business of the armed conflict in
Ukraine, see “Key Information Risk Factors Risks Relating to Our Business and Industry The Russia-Ukraine armed
conflict may adversely affect our operations”.
Tenaris is building a wind farm in Argentina at a cost of approximately $200 million which is expected to reduce our
CO
2
emissions in that country by around 150,000 tons per year and supply close to 50% of the electric energy
requirements at our Siderca integrated seamless pipe mill.
Ferroalloys
The purchase of ferroalloys is coordinated globally to ensure supply for each of our steel shops. International prices of
ferroalloys can vary substantially within a short period of time.
Prices for the main ferroalloys consumed by Tenaris increased significantly during the first half of 2022 (reaching
highest levels since 2008). In the second half of 2022 prices suffered a sharp drop but still remained above pre
pandemic levels.
The main drivers for the price peak seen in the first half of 2022 were the world’s economic recovery after the COVID-
19 pandemic, supporting increased steel production coupled with supply disruptions due to the Russia-Ukraine conflict
(as both are significant ferroalloy producers).
During the second half of 2022 global steel production slowed, especially in Europe as several mills shut down their
furnaces due to high energy costs and lower steel demand. In China, demand was also affected by the country’s
restrictive COVID-19 policies. As a result, ferroalloy prices decreased on lower demand. Molybdenum prices, however,
remained strong and rose considerably mainly due to supply shortages from many mining companies that are struggling
with quality issues and labor shortages, as well as better supported demand from both the oil and gas industry and the
automotive sector´s continued production recovery as component shortages subside.
Product Quality Standards
Our steel products (tubular products, accessories and sucker rods) are manufactured in accordance with the applicable
specifications of the American Petroleum Institute (“API”), the American Society for Testing and Materials (“ASTM”),
the International Standardization Organization (“ISO”), and European Standards (“EN”), among other standards. The
products must also satisfy our proprietary standards as well as our customers’ requirements. We maintain an extensive
quality control and assurance program to guarantee that our products and services consistently meet proprietary and
industry standards bringing a high level of competitiveness.
We currently maintain, for all our manufacturing facilities and service centers, a Quality Management System certified
to ISO 9001 by Lloyd’s Register Quality Assurance and API product licenses granted by API, which are requirements for
selling to the major oil and gas companies and have rigorous quality standards. In addition, the majority of our testing
laboratories are certified to ISO 17025. Our Quality Management System (“QMS”), based on ISO 9001, API Q1 and API

51
Q2 specifications, guarantees that products and services comply with customer requirements from the acquisition of
raw materials to the delivery of the final product and services. The QMS is designed to ensure the reliability and
improvement of the product and the manufacturing operations processes as well as the associated services.
Additionally, we have certified the QMS to API Q2 at certain locations, a certification specifically developed for
companies that offer services in the oil and gas industry.
All of our mills involved in the manufacturing of material for the automotive market are certified according to the
standard IATF 16949 by Lloyd’s Register Quality Assurance.
Research and Development
R&D of new products and processes to meet the increasingly stringent requirements of our customers is an important
aspect of our business.
R&D activities are carried out primarily at our global R&D network managed and coordinated through its main office in
Amsterdam, the Netherlands and specialized research and testing facilities located in Campana, Argentina, in Veracruz,
Mexico and in Dalmine, Italy. Additionally, we have a Technology Center in Houston, Texas, where we develop our
TenarisHydril Wedge technology. Our R&D capabilities are expanded through the engagement and collaboration with
some of the world’s leading industrial research institutions to solve the problems posed by the complexities of oil and
gas, automotive and mechanical pipe projects with innovative applications. In addition, our global Product Engineering
and Technical Sales team is made up of experienced engineers who work with our customers to identify solutions for
each particular oil and gas drilling environment.
Product R&D currently being undertaken is focused on the challenging energy markets, which are lately characterized
by increasingly efficient oil and gas activities together with growing energy transition related initiatives.
Product R&D includes:
proprietary Premium Joint products (OCTG) including Dopeless® technology;
proprietary steels for various applications (oil and gas drilling and transportation, hydrogen transportation and
storage, carbon dioxide transportation and injection, automotive, etc.);
heavy-wall deepwater line pipe, risers and welding technology;
tubes and components for the automotive industry and other mechanical applications;

We seek to protect our innovations and developments in products and processes through patents, trade secrets,
trademarks and other intellectual property tools that allow us to keep our competitiveness and differentiate ourselves
from our competitors.
We spent $50.7 million in R&D in 2022, compared to $45.3 million in 2021 and $41.8 million in 2020.
Capitalized costs were not material for the years 2022, 2021 and 2020.
Environmental, Social and Governance (“ESG”) Regulation
We are subject to a wide range of local, provincial and national laws, regulations, permit requirements and decrees
relating to environmental, social and governance matters, including laws and regulations relating to climate-change
mitigation, use of resources, hazardous materials and radioactive materials, and air emissions, water discharges and
waste management; legislation on human rights and modern slavery; human capital, including equal opportunity,
gender and disabilities equality, working conditions, work-life balance, and labor market access; and applicable rules on
internal control and risk management, anti-corruption, business partner relationship management and other
governance issues. For more information on the Company’s governance practices and applicable regulation, see
“Directors, Senior Management and Employees” and “Corporate Governance Statement Corporate Governance”.
ESG regulation has been evolving over the past years and is expected to continue to evolve in the future, particularly
with respect to environmental matters. Laws and regulations protecting the environment have become increasingly
complex and more stringent and expensive to implement in recent years. Environmental requirements vary from one
jurisdiction to another adding complexity to the operations of global companies, such as Tenaris.
The Paris Agreement, adopted at the 2015 United Nations Climate Conference, sets out the global framework to limit
the rising temperature of the planet and to strengthen the countries’ ability to deal with the effects of climate change.
In order to achieve climate neutrality by the year 2050, the European Commission has laid out several action plans,
such as the EU climate adaptation strategy, sustainable finance policies and the raw materials alliance. In addition, the
EU Non-Financial Reporting Directive provides the legal framework for annual disclosure of non-financial information
and, the EU Taxonomy Regulation establishes a classification system for environmentally sustainable economic
activities, laying out definitions to businesses, stakeholders and policymakers on which economic undertakings can be
considered environmentally sustainable and requiring companies to disclose, in the annual reports, how
environmentally sustainable their economic activities are. More recently, as part of the European Green Deal, the EU
adopted the Corporate Sustainability Reporting Directive, which requires European large companies and listed issuers
to disclose information on their risks and opportunities arising from social and environmental issues, and on the
impacts of their activities on people and the environment. In the case of Tenaris, the EU Corporate Sustainability
Reporting Directive will apply with respect to the Company’s 2024 annual report and will replace non-financial
disclosure obligations under the EU Non-Financial Reporting Directive.
Similarly, in response to an increasing investor focus and reliance on climate and ESG-related disclosure and
investment, the SEC announced in March 2021 the creation of a Climate and ESG Task Force to identify ESG-related
misconduct and potential violations, and in March 2022, the SEC proposed rule changes that would require registrants
to include certain climate-related disclosures in their periodic reports, including information about climate-related risks
that are reasonably likely to have a material impact on their business, results of operations, or financial condition, and
certain climate-related financial statement metrics in a note to their audited financial statements. The SEC’s proposal
on climate-change disclosure has received strong pushback from investors, companies and lawmakers. Although the
revised rules have not been adopted yet, they evidence the SEC’s increased concern and focus ESG-related matters.
For more information on the impact of climate change legislations, increasing regulatory requirements and significant
technology and market changes, see “Key Information Risk Factors - Risks Relating to Our Business and Industry
Climate change legislation and increasing regulatory requirements aimed at transitioning to a lower-carbon economy
may reduce demand for our products and services and result in unexpected capital expenditures and costs, and
negatively affect our reputation”. For more information on the steps taken by Tenaris to address climate change
challenges, see “Operating and Financial Review and Prospects Overview Climate Change”.
The ultimate impact of complying with ESG regulations, in particular with applicable environmental regulation, is not
always clearly known or determinable because certain laws and regulations have been evolving in the past years or are
under constant review by competent authorities. The expenditures required to comply with these laws and regulations,
including site or other remediation costs, or costs incurred from potential environmental liabilities, could have a

Graphics

53
material adverse effect on our financial condition and profitability. While we incur, and will continue to incur, in
expenditures to comply with applicable laws and regulations, there always remains a risk that environmental incidents
or accidents may occur that may negatively affect our reputation or our operations. For more information on risks and
costs related to compliance with environmental regulation and product liability, see “Key Information Risk Factors -
Risks Relating to Our Business and Industry The cost of complying with environmental regulations and potential
environmental and product liabilities may increase our operating costs and negatively impact our business, financial
condition, results of operations and prospects”.
Compliance with applicable ESG regulation is of utmost importance to the Company and a significant factor in our
industry and business. We have not been subject to any significant penalty for any material violation of applicable ESG
regulations, including for any material violation of environmental laws and regulations in 2022, 2021 and 2020 and we
are not aware of any current material legal or administrative proceedings pending against us with respect to ESG
matters, which could have an adverse material impact on our financial condition or results of operations.
Insurance
We carry property damage, general liability and certain other insurance coverage in line with industry practice.
However, we do not carry business interruption insurance. Our current general liability coverage includes third party,
employers, sudden and accidental seepage and pollution and product liability, up to a limit of $300 million. Our current
property insurance has an indemnification cap up to $250 million for direct damage, considering all plants; and a
deductible of $75 million.
Disclosure Pursuant to Section 13(r) of the Exchange Act
Tenaris
The Iran Threat Reduction and Syria Human Rights Act of 2012, created a new subsection (r) in Section 13 of the U.S.
Securities Exchange Act of 1934, as amended (the “Exchange Act”), which requires a reporting issuer to provide
disclosure if the issuer or any of its affiliates knowingly engaged in certain enumerated activities relating to Iran,
including activities involving the Government of Iran. The Company is providing the following disclosure pursuant to
Section 13(r) of the Exchange Act.
In July 2015, the Islamic Republic of Iran entered into the Joint Comprehensive Plan of Action (“JCPOA”) with China,
France, Germany, Russia, the United Kingdom and the United States, which resulted in the partial lifting in January 2016
of certain sanctions and restrictions against Iran, including most U.S. secondary sanctions against such country. On May
8, 2018, the United States announced that it would cease participation in the JCPOA and would begin re-imposing
nuclear-related sanctions against Iran after a wind-down period. Following the U.S. withdrawal from the JCPOA, the
European Union updated Council Regulation (EC) No. 2271/96 of 22 November 1996 (the “EU Blocking Statute”), to
expand its scope to cover the re-imposed U.S. nuclear-related sanctions. The EU Blocking Statute aims to counteract
the effects of the U.S. secondary sanctions.
As previously reported, Tenaris ceased all deliveries of products and services to Iran by the end of October 2018, that is,
during the wind-down period and before the full reinstatement of U.S. secondary sanctions on November 5, 2018.
Tenaris has not, directly or indirectly, delivered any goods or services to Iran or Iranian companies during 2022 and
does not intend to explore any commercial opportunities in Iran, nor does it intend to participate in tender offers by, or
issue offers to provide products or services to, Iranian companies or their subsidiaries.
As of December 31, 2022, the Company’s subsidiary, TGS, maintains an open balance for an advance made by Toos
Payvand Co. for approximately EUR0.04 million (approximately $0.04 million) for goods that remained undelivered
following the reinstatement of U.S. secondary sanctions.

All revenue and profit derived from Tenaris’s sales to Iran was recorded in the fiscal year in which such sales were
performed and, therefore, no revenue and profit has been reported in connection with commercial activities related to
Iran for the year ended December 31, 2022.
The Company has procedures in place designed to ensure that its activities comply with all applicable U.S. and other
international export control and economic sanctions laws and regulations.
Tenaris’s Affiliates
Pursuant to Section 13(r) of the Exchange Act, the Company is also required to disclose whether any of its affiliates
have engaged in certain Iran-related activities and transactions. No affiliate of the Company reported any Iran related
activity for the year ended December 31, 2022.

Other Investments
Ternium
We have a significant investment in Ternium, a Luxembourg company controlled by San Faustin, whose securities are
listed on the NYSE. As of December 31, 2022, the Company held 11.46% of Ternium’s share capital (including treasury
shares).
The Company is a party to a shareholders’ agreement with Techint Holdings S.àr.l. (“Techint Holdings”), a wholly owned
subsidiary of San Faustin and Ternium’s main shareholder, dated January 9, 2006, pursuant to which Techint Holdings is
required to take actions within its power to cause one of the members of Ternium’s board of directors to be nominated
by the Company and any directors nominated by the Company to be removed only pursuant to previous written
instructions from the Company. The Company and Techint Holdings also agreed to cause any vacancies on Ternium’s
board of directors to be filled with new directors nominated by either the Company or Techint Holdings, as applicable.
The shareholders’ agreement will remain in effect so long as each of the parties holds at least 5% of the shares of
Ternium or until it is terminated by either the Company or Techint Holdings pursuant to its terms. Carlos Condorelli was
nominated by the Company as a director of Ternium pursuant to this shareholders’ agreement.
The following factors and circumstances evidence that Tenaris has significant influence over Ternium:
both the Company and Ternium are under the indirect common control of San Faustin;
four out of nine members of Ternium’s board of directors (including Ternium’s Chairman) are also members of the
Company’s board of directors;
the Company is entitled to nominate one director to Ternium’s board of directors pursuant to the shareholders’
agreement between the Company and Techint Holdings described above.
Usiminas
At December 31, 2022, Tenaris held, through its Brazilian subsidiary Confab, 36.5 million ordinary shares and 1.3 million
preferred shares of Usiminas, representing 5.19% of its shares with voting rights and 3.07% of its total share capital.
Confab’s acquisition of the Usiminas shares was part of a larger transaction performed on January 16, 2012, pursuant to
which Tenaris’s affiliate Ternium (through certain of its subsidiaries) and Confab acquired a large block of Usiminas
ordinary shares and joined Usiminas’ existing control group. Subsequently, in 2016, Ternium and Confab subscribed to
additional ordinary shares and to preferred shares.
At December 31, 2022, the Usiminas control group held, in the aggregate, 483.6 million ordinary shares bound to the
Usiminas shareholders’ agreement, representing approximately 68.6% of Usiminas’ voting capital. The Usiminas control
group, which is bound by a long-term shareholders’ agreement that governs the rights and obligations of Usiminas
control group members, is currently composed of three sub-groups: the T/T Group, comprising Confab and certain
Ternium entities; the NSC Group, comprising NSC, Metal One Corporation and Mitsubishi Corporation; and Usiminas’
pension fund Previdência Usiminas. The T/T Group holds approximately 47.1% of the total shares held by the control
group (39.5% corresponding to the Ternium entities and the other 7.6% corresponding to Confab); the NSC Group holds
approximately 45.9% of the total shares held by the control group; and Previdência Usiminas holds the remaining 7%.
The corporate governance rules reflected in the Usiminas shareholders’ agreement include, among others, an
alternation mechanism for the nomination of each of the chief executive officer (“CEO”) and the chairperson of the
board of directors of Usiminas, as well as a mechanism for the nomination of other members of Usiminas’ executive
board. The Usiminas shareholders’ agreement also provides for an exit mechanism consisting of a buy-and-sell
procedure (exercisable at any time after November 16, 2022, and applicable with respect to shares held by NSC and the
T/T Group), which would allow either Ternium or NSC to purchase all or a majority of the Usiminas’ shares held by the
other shareholder.
Confab and the Ternium entities party to the Usiminas shareholders’ agreement have a separate shareholders
agreement governing their respective rights and obligations as members of the T/T Group. Such separate agreement
includes, among others, provisions granting Confab certain rights relating to the T/T Group’s nomination of Usiminas’
officers and directors under the Usiminas shareholders’ agreement. Those circumstances evidence that Tenaris has

Graphics

significant influence over Usiminas, and consequently, Tenaris accounts for its investment in Usiminas under the equity
method (as defined by IAS 28).
On March 30, 2023, the Company’s subsidiary, Confab, together with Tenaris’s affiliates Ternium Investments S.àrl and
Ternium Argentina, entered into a share purchase agreement to acquire from the NSC Group, pro rata to their current
participations in the T/T Group, 68.7 million ordinary shares of Usiminas, increasing Tenaris’s participation in the
Usiminas control group to 9.8%. Upon the closing of the transaction, the existing shareholders agreement will be
replaced by a new shareholders agreement setting forth a new governance structure for Usiminas. For more
information on the recently announced agreement for the purchase of Usiminas shares from the NSC Group, see
“Financial Information Significant Changes”.

Techgen

Techgen is a Mexican joint venture company owned 48% by Ternium, 30% by Tecpetrol and 22% by Tenaris. Techgen
operates a natural gas-fired combined cycle electric power plant in the Pesquería area of the State of Nuevo León,
Mexico. Tenaris, Ternium and Tecpetrol are parties to a shareholders’ agreement relating to the governance of
Techgen.
In the last few years, the Mexican government made various attempts to modify rules and regulations governing the
energy market in Mexico with potential impact on the energy supply and its cost. For more information on the risks
associated with the energy reform in Mexico, see “Key Information Risk Factors Risks Relating to Our Business and
Industry Adverse economic or political conditions in the countries where we operate or sell our products and services
may decrease our sales or disrupt our manufacturing operations, thereby adversely affecting our revenues, profitability
and financial condition”.
GPC
GPC is a Saudi-German joint venture, established in 2010 and located in Jubail, Saudi Arabia, which manufactures LSAW
pipes. Tenaris, through its subsidiary Saudi Steel Pipe Company (“SSPC”), currently owns 35% of the share capital of
GPC. In accordance with GPC’s bylaws, SSPC’s 35% equity interest entitles SSPC to appoint four of the eleven members
of the board of directors of GPC. In addition, SSPC has the ability to block any shareholder resolution.

In December 2022, EEW, a German company that owns another 35% interest in GPC, expressed its intention to sell its
entire interest in GPC for a cash amount of $9.9 million. SSPC and another shareholder that owns a 20% interest in GPC
exercised their respective rights of first refusal. Each such acquisition is subject to customary conditions, including
competition clearance and bank consents. If both acquisitions are consummated, SSPC will acquire a 22.3% additional
interest in GPC (thus totaling a 57.3% interest).

Operating and Financial Review and Prospects
The following discussion and analysis of our financial condition and results of operations are based on, and should be
read in conjunction with, our audited consolidated financial statements and the related notes included elsewhere in
this annual report. This discussion and analysis present our financial condition and results of operations on a
consolidated basis. We prepare our consolidated financial statements in conformity with IFRS. IFRS differ in certain
significant respects from U.S. GAAP.
Certain information contained in this discussion and analysis and presented elsewhere in this annual report, including
information with respect to our plans and strategy for our business, includes forward-looking statements that involve
risks and uncertainties. See “Cautionary Statement Concerning Forward-Looking Statements. In evaluating this
discussion and analysis, you should specifically consider the various risk factors identified in “Key Information Risk
Factors”, other risk factors identified elsewhere in this annual report and other factors that could cause results to differ
materially from those expressed in such forward-looking statements.
Overview
We are a leading global manufacturer and supplier of steel pipe products and related services for the energy industry
and other industries
We are a leading global manufacturer and supplier of steel pipe products and related services for the world’s energy
industry as well as for other industrial applications. Our customers include many of the world’s leading oil and gas
companies, engineering companies engaged in constructing oil and gas gathering and processing and power facilities,
and industrial companies operating in a range of industries. We operate an integrated worldwide network of steel pipe
manufacturing, research, finishing and service facilities with industrial operations in the Americas, Europe, Asia and
Africa and a direct presence in most major oil and gas markets.
Our main source of revenue is the sale of products and services to the oil and gas industry, and the level of such sales is
sensitive to international oil and gas prices and their impact on drilling activities
Demand for our products and services from the global oil and gas industry, particularly for tubular products and
services used in drilling operations, represents a substantial majority of our total Tubes sales. Our sales, therefore,
depend on the condition of the oil and gas industry and our customers’ willingness to invest capital in oil and gas
exploration and development as well as in associated downstream processing activities. The level of these expenditures
is sensitive to oil and gas prices as well as the oil and gas industry’s view of such prices in the future. Prices fell to
historically low levels in the wake of the COVID-19 pandemic and the accompanying collapse in global oil consumption,
but subsequently recovered exceeding pre-pandemic levels, particularly in the immediate aftermath of the Russian
invasion of Ukraine and the imposition of sanctions on Russian exports of oil and gas. Prices have since fallen back from
their highs but global oil and LNG prices remain at levels around $80/bbl and $17 per million BTU respectively, which
should support further investment in production, although North American natural gas prices (Henry Hub) have fallen
below $3 per million BTU in early 2023 as production rose while the weather during the winter heating season has been
unusually mild and one of the main U.S. LNG export terminals has been temporarily closed.
In 2020, the collapse in oil consumption and prices in the wake of the COVID-19 pandemic, deeply affected worldwide
drilling activity, as represented in the number of active drilling rigs published by Baker Hughes. This was particularly the
case in the Americas, where, in the U.S. for example, drilling activity dropped 54% compared to the previous year.
Drilling activity in the Americas recovered along with oil and gas prices in 2021 and 2022. The drop in drilling activity in
the Eastern Hemisphere was less pronounced and took longer to manifest itself and the subsequent recovery started
later and has been more gradual.
Prior to the 2014 downturn in oil prices, a growing proportion of exploration and production spending by oil and gas
companies had been directed at offshore, deep drilling and non-conventional drilling operations in which high-value
tubular products, including special steel grades and premium connections, are usually specified. The success, however,
of shale drilling operators, with their inherently short investment cycles, in adapting to lower oil and gas prices and
increasing production, and the increasing share of oil produced in shale plays as a proportion of global supply, has led
to a slowdown in new developments of complex offshore projects with long investment lead times in a context of low
and more volatile oil prices, consequently affecting the level of product differentiation. More recently, however,
offshore drilling activity has increased again as exploration has continued and cost-competitive developments, like
those in Brazil, Guyana, and sub-Saharan Africa, are being sanctioned and developed.

Our business is highly competitive
The global market for steel pipes is highly competitive, with the primary competitive factors being price, quality, service
and technology. We sell our products in a large number of countries worldwide and compete primarily against
European and Japanese producers in most markets outside North America. In the United States and Canada, we
compete against a wide range of local and foreign producers. Over the past two decades, substantial investments have
been made, especially in China but also in other regions around the world, to increase production capacity of seamless
steel pipe products. Production capacity for more specialized product grades has also increased. With the downturn in
the price of oil and demand for tubes for oil and gas drilling between 2014 and 2016, the overcapacity in steel pipe and
seamless steel pipe production worldwide became acute, extending beyond commodity grades. This situation has been
accentuated by the more recent COVID-19 induced collapse in demand and the prospect of an accelerated energy
transition. The competitive environment is, as a result, intense, and we expect that this can only continue without
substantial capacity reductions. Effective competitive differentiation and industry capacity closures will be key factors
for Tenaris.
In addition, there is an increased risk of unfairly traded steel pipe imports in markets in which we produce and sell our
products. In September 2014, the United States imposed anti-dumping duties on OCTG imports from various countries,
including South Korea. Despite the duties imposed, imports from South Korea continued at a very high level. As a result,
U.S. domestic producers have requested successive reviews of South Korea’s exports, which are ongoing. At the same
time South Korean producers have appealed the duties imposed. Similarly, in Canada, the Canada Border Services
Agency introduced anti-dumping duties on OCTG imports from South Korea and other countries in April 2015.
During 2018, in addition to anti-dumping duties, the U.S. government introduced tariffs and quotas pursuant to Section
232 on the imports of steel products, including steel pipes, with the objective of strengthening domestic production
capacity utilization and investment. Quotas were imposed on the imports of steel products from South Korea, Brazil
and Argentina, while 25% tariffs were imposed on imports from most other countries, except Australia. The proportion
of the OCTG market supplied by imports declined from around 60% prior to the imposition of tariffs and quotas to
around 40% at the end of 2020 but has since increased to around 50%.
We are also exposed to the risk that our competitors may seek to initiate anti-dumping cases against our exports. In
2021, anti-dumping cases were initiated against our exports from Mexico into Canada as well as against our exports
from Mexico and Argentina into the United States. In Canada, a final determination of no injury was issued in January
2022 with respect to our imports from Mexico. In the United States, a final determination of injury was issued in
October 2022 against our imports from Mexico and Argentina and antidumping duty deposits of 44.93% and 78.30%
were imposed on our imports from Mexico and Argentina, respectively. These deposit rates may be reset periodically
based on the results of an administrative review process. Tenaris has appealed the duty ruling regarding imports from
Mexico and Argentina.
Our production costs are sensitive to prices of steelmaking raw materials and other steel products
We purchase substantial quantities of steelmaking raw materials, including ferrous steel scrap, DRI, pig iron, iron ore
and ferroalloys, for use in the production of our seamless pipe products. In addition, we purchase substantial quantities
of steel coils and plates for use in the production of our welded pipe products. Our production costs, therefore, are
sensitive to prices of steelmaking raw materials and certain steel products, which reflect supply and demand factors in
the global steel industry and in the countries where we have our manufacturing facilities.
The costs of steelmaking raw materials and of steel coils and plates increased during 2021, reaching all-time highs. As a
reference, prices for hot rolled coils, HRC Midwest USA Mill, published by CRU, averaged $1,734 per metric ton in 2021
and $632 per metric ton in 2020. Since this increase occurred when drilling activity was only beginning its recovery from
the pandemic-induced collapse, the production of welded pipes in the United States was not economic. It was not until
2022, when hot rolled coil prices averaged $1,128 per ton and drilling activity recovered to a large extent that welded
OCTG production again became economic and we were able to resume welded OCTG production in the United States.
Summary of results
In 2022, our net income reached a record high while our net sales and EBITDA
1
were close to the all-time highs
recorded in 2008 just prior to the global financial crisis. Our results rose strongly throughout the year and reached
record quarterly levels in the fourth quarter. The increase in sales reflects the strong recovery of oil and gas drilling

activity in the Americas, a more delayed recovery in Eastern Hemisphere activity, which is now picking up steam, and
the solid contribution of the great majority of our market and product segments.
Operating margins expanded reflecting the higher prices realized on the sales of most of our products that have more
than compensated for higher raw material and energy costs and a good industrial performance with increased levels of
activity and utilization of production capacity.
Net income more than doubled compared to 2021, despite a much lower contribution from our non-consolidated
companies and higher income taxes.
Operating cash flow for the year amounted to $1,167 million after accounting for a $2,131 million build up in working
capital to support the higher level of sales and the ramp up of our industrial system. After capital expenditures of $378
million and dividend payments of $531 million during the year, our net cash position increased to $921
2
million at the
end of the year.
Climate Change
Tenaris recognizes that climate change presents significant risks to society in general and to its business in particular,
taking into account the markets where we operate, the potential impact of government regulations on our operations
and those of our customers, and the location of our physical assets. Tenaris also acknowledges that climate change
offers strategic opportunities to consolidate its leading market position and diversify sales. For more information on
risks relating to climate change regulations, see “Risks Relating to Our Business and Industry - Climate change legislation
and increasing regulatory requirements aimed at transitioning to a lower-carbon economy may reduce demand for our
products and services and result in unexpected capital expenditures and costs, and negatively affect our reputation”.
For more information on the physical risks resulting from climate change, see “Risks Relating to Our Business and
Industry - The physical risks resulting from climate change, including extreme weather conditions and shifts in weather
patterns, have in the past and may in the future adversely affect our operations and financial results”.
Given the relevance of climate change for Tenaris’s overall business and strategy, the Company’s board of directors
reviews the development and implementation of our strategy to address climate change on a quarterly basis. The
Company’s board of directors has appointed its Vice-Chairman, Germán Curá, to take responsibility for this topic and
keep it informed of the progress made.
As part of our efforts to address climate change, we are investing in and adapting our operations to reduce their carbon
intensity, and developing products and services for use in low-carbon energy applications. We regularly assess and
track global progress towards the energy transition, monitoring the goals, policies, regulations, technologies and other
global and national developments that may speed up or hinder the progress of this transition in the years ahead, or
may present any risks to our operations.
We continue to strengthen our disclosure of climate change-related information in accordance with the most relevant
international frameworks and standards that are being developed. This year, for example, we are reporting our carbon
dioxide emissions using the Greenhouse Gas Protocol (“GHG Protocol”) methodology, which, despite differences with
World Steel Association’s (“worldsteel) methodology, does not materially alter past reported results.
We work closely with our customers as they seek to establish sustainable sourcing policies throughout their supply
chain, thus requiring a more specific disclosure of climate change-related impacts. For this purpose, we have joined the
Carbon Disclosure Project (CDP) and are using the Ecovadis and Open-es sustainability assessment platforms, among
others.
We also encourage the use of sustainable practices among our suppliers and are introducing a Sustainable Sourcing
Policy to strengthen our efforts in this area.
EAF producer
All the steel we manufacture is produced in electric arc furnaces using recycled steel scrap as the primary source of
metallic feedstock. We supplement the use of steel scrap with metallic raw materials such as pig iron, direct reduced

61
iron and ferroalloys to meet quality, productivity and materials specification requirements. In Argentina, where the
availability of steel scrap is limited, we operate a facility to produce direct reduced iron using natural gas.
Steel produced in electric arc furnaces using a high proportion of scrap in the metallic charge generally has a
substantially lower carbon intensity than steel produced using iron ore and metallurgical coal as the primary feedstock.
The carbon emissions intensity for steel products produced at our steel manufacturing sites is around 40% below the
average for the global steel industry (as reported by worldsteel).
We also purchase steel from third-party suppliers, primarily for the production of welded pipe products. As many of
these suppliers produce steel products using iron ore and coal, the carbon emissions intensity of our pipes produced
with this steel is often higher than that of those manufactured using our own steel.
Reducing the carbon intensity of our operations
In February 2021, we set a medium-term target to reduce the carbon emissions intensity of our operations by 30% by
the year 2030, compared to a 2018 baseline, considering Scopes 1, 2 and 3 emissions. Within Scope 3 emissions, the
target considers emissions related to raw materials and steel purchased from third parties, which represents the largest
source of our Scope 3 emissions.
To achieve this target, we have increased the proportion of recycled steel scrap in the metallic mix used for the steel we
produce, and we are investing in projects to continue improving energy efficiency and increasing the share of
renewable or low-carbon electricity, as well as investing to further improve scrap handling and collection in our
operations.
In 2022, we invested $110 million in projects which are expected to help reduce the carbon intensity of our operations
and improve their environmental performance. We expect investments in such projects to increase further, accounting
for some 30% of our total capital expenditure in 2023.

We have already made good progress towards this strategic objective. By focusing on energy efficiency and increasing
the proportion of steel scrap used in our electric furnaces, the carbon emissions intensity of our tubular operations has
declined to 1.17 tons of CO
2
equivalent per ton of steel processed. This compares with the 1.43 tons of CO
2
equivalent per ton of steel processed in 2018. Our emissions refer to the GHG Protocol, and have been reviewed by
our external auditors.
Much of the reduction in emissions intensity achieved to-date has been through increasing scrap use and reducing the
use of purchased pig iron, thus reducing Scope 3 emissions. In 2022, however, Scope 3 emissions intensity rose as we
increased the proportion of welded steel pipes in our mix to meet the strong demand for pipeline projects in Latin
America and the Middle East. Both the demand for pipeline projects and Scope 3 emissions are expected to rise further
in 2023. Nevertheless, we were able to reduce Scope 1 emissions intensity in 2022, largely through greater energy
efficiency, and will continue investing in this area as well as in higher scrap use.

We are also investing in reducing Scope 2 emissions intensity by using renewable energy at our facilities around the
world. We are building a wind farm in Argentina with an investment of approximately $200 million, due to come into
operation in the second half of 2023. The wind farm project is expected to reduce our CO
2
emissions in Argentina by
some 150,000 tons per year, supply close to 50% of the electricity requirements at our Siderca mill, and reduce our
exposure to government-fixed electric power prices. In Europe, we are making some small renewable energy
investments, seeking further opportunities to increase renewables use at our sites.
Our medium-term target to reduce the carbon intensity of our operations is the first step toward decarbonizing them to
reach net zero carbon emissions. The timing for achieving this goal depends on different factors, such as emerging
technologies as well as market and regulatory conditions, including carbon pricing and customer support. We are
allocating substantial resources to our decarbonization strategy, which we also expect to boost our competitive
positioning.
As we pursue our strategy of decarbonizing our operations, we are exploring a range of possibilities with our partners
from around the world, knowing that there is no one solution and certain alternatives are better suited to specific sites

or regions, depending on local infrastructure, resources, and conditions. As industry leaders, we seek to be competitive
in offering our customers low-carbon products.
Internal carbon price and financial considerations
To accelerate the fulfilment of our decarbonization targets and anticipate the future implementation of carbon pricing
mechanisms around the world, we have introduced an internal carbon price at a minimum of $80/ton. This internal
carbon price is primarily used to evaluate investments in projects that could contribute to lower carbon emissions and
decarbonize our operations.
We constantly monitor the evolution of our main customers’ strategies and scenarios for future energy demand,
considering the global objectives to address climate change by reducing carbon emissions as well as governments’
objectives to achieve a carbon-neutral economy. We also assess the future market outlook for our products with
reference to the different scenarios for oil and gas demand published by our customers, international agencies such as
the International Energy Agency (IEA), and expert energy market consultancies, such as Rystad Energy (“Rystad”).
We pay particular attention to the historical record and potential pace of change in the adoption of new technologies,
regulations and behaviors which may affect future oil and gas demand. These scenarios and assessments provide
fundamental input for formulating and evaluating our business strategy and how we address the risks and
opportunities posed by climate change.
There are many potential outcomes and much uncertainty about the pace at which the transition may be accomplished
as we move from today’s use of fossil fuels, including oil and gas, to cleaner fuels, while overall energy demand is
expected to rise. Tenaris takes these risks into consideration when evaluating its investments in projects and the
acquisition of equipment to produce steel pipes, factoring them into the accounting estimates and assumptions used to
assess the carrying value of its assets.
Products for the energy transition
As suppliers of tubular products and services to the energy industry, we see in the energy transition an opportunity to
develop new products and services for potentially fast-growing segments like hydrogen transportation and storage, CCS
and geothermal installations. In the past two years, we have increased investments in R&D and our organizational focus
in these areas, which are expected, eventually, to contribute a relevant revenue stream.
We have developed a range of materials technologies suitable for use in hydrogen storage and transportation, where
there is growing demand for large, high-pressure vessels used in the build-out of hydrogen refueling stations for heavy-
duty vehicles and buses, mostly in Europe and California. We are also seeing increasing interest from customers in
developing CCS projects.
During 2022, we delivered the pipes for a pipeline for the Northern Lights CCS project in Norway. Following extensive
product testing, we were awarded a contract to supply casing for CO
2
injection wells for the UK’s HyNet project.
Outlook
In an environment where geopolitical and macro-economic risks as well as inflation remain high, global economic
prospects have improved following the fall in energy prices in Europe and the reversal of China’s COVID lockdown
policy. Conditions remain in place for a further increase in investment in the energy industry, with low levels of spare
capacity, the implementation of further sanctions on Russian exports and a renewed focus on energy security around
the world.
Drilling activity increased during 2022 and, although it has plateaued in North America as we enter 2023, it continues to
increase in the Middle East and offshore regions. Global demand for OCTG in 2023 is expected to reach its highest level
since 2014. Pipeline activity is also advancing to support oil and gas developments, notably in Argentina and the Middle
East.
For the first half of 2023, we expect our sales and EBITDA
3
to show a further increase as we continue to ramp up
production in North America and increase shipments to pipeline projects. The pricing momentum we saw over the last
3

year is levelling out and we expect that margins will remain close to the current level. Cash flow from operations will
increase and we expect to stabilize our working capital requirements by the second quarter.
Functional and presentation currency
The functional and presentation currency of the Company is the U.S. dollar. The U.S. dollar is the currency that best
reflects the economic substance of the underlying events and circumstances relevant to Tenaris’s global operations.
Starting January 1, 2023, the Company changed the functional currency of its Brazilian subsidiaries, from the Brazilian
Real to the U.S. dollar.
This decision is a result of a significant increase of its Brazilian Subsidiaries’ participation in the OCTG and line pipe
international markets, a trend which started in recent years and intensified in 2022, a greater level of integration of the
local operations within Tenaris’s international commercial and supply chain system, as well as the fact that the main
purchase agreement contracts and the long term sales agreement contracts with major international and local oil
companies are both indexed to the U.S. dollar. Local steel prices are also being affected by the U.S. dollar / Brazilian
Real fluctuations.
As a result of this change, except for the Italian subsidiaries whose functional currency is the Euro, Tenaris determined
that the functional currency of its other subsidiaries is the U.S. dollar, based on the following principal considerations:
sales are mainly negotiated, denominated and settled in U.S. dollars. If priced in a currency other than the U.S.
dollar, the sales price may consider exposure to fluctuation in the exchange rate versus the U.S. dollar;
prices of critical raw materials and inputs are priced and settled in U.S. dollars;
transaction and operational environment and the cash flow of these operations have the U.S. dollars as
reference currency;
significant level of integration of local operations within Tenaris’s international global distribution network;
net financial assets and liabilities are mainly received and maintained in U.S. dollars; and
the exchange rate of certain legal currencies has long been affected by recurring and severe economic crises.
Results of operations for subsidiaries whose functional currencies are not the U.S. dollar are translated into U.S. dollars
at the average exchange rates for each quarter of the year. Financial statement positions are translated at the year-end
exchange rates. Translation differences are recognized in a separate component of equity as currency translation
adjustments. In the case of a sale or other disposal of any of such subsidiaries, any accumulated translation difference
would be recognized in the Consolidated Income Statement as a gain or loss from the sale or disposal.

Net sales of tubular products and services increased 86% to $11,133 million in 2022, compared to $5,994 million in
2021, reflecting a 26% increase in volumes and a 47% increase in average selling prices. Sales increased in all regions,
mainly in North America where there was a recovery in volumes and prices throughout the region, led by the U.S.
onshore market and in South America mainly due to higher OCTG sales in the region and deliveries for a gas pipeline in
Argentina.
Operating results from tubular products and services, amounted to a gain of $2,867 million in 2022, compared to a gain
of $613 million in 2021. Tubes operating income in 2022 is net of a $63 million impairment charge, while in 2021 it
includes an impairment charge of $57 million. The improvement in operating results was driven by the recovery in
shipment volumes and in prices and higher level of utilization of production capacity, which more than offset an
increase in energy and raw material costs.

Net sales of other products and services increased 19% from $528 million in 2021 to $630 million in 2022, mainly due to
higher sales of sucker rods, of our oilfield services business in Argentina which offers hydraulic fracturing and coiled
tubing services and excess raw materials, partially offset by lower sales from the discontinued industrial equipment
business in Brazil.
Operating results from other products and services, amounted to a gain of $96 million in 2022, similar to the $95 million
gained in 2021. Results were mainly derived from our sucker rods business and our oilfield services business in
Argentina, partially offset by a $20 million loss related to our discontinued industrial equipment business in Brazil. The
operating income for other products and services in 2022 includes a $14 million impairment charge.
Selling, general and administrative expenses, or SG&A, amounted to $1,635 million (13.9% of net sales), compared to
$1,207 million (18.5%) in 2021. The 2022 increase in SG&A is mainly due to higher logistic costs, while they decrease as
a percentage of sales.
Impairment charge. In 2022, we recorded a $77 million impairment: $63 million on our Tubes segment and $14 million
on our Others segment, while in 2021 we recorded a $57 million impairment on our Tubes segment, as a result of the
termination of the NKKTubes joint venture.
Other operating results amounted to zero in 2022, compared to a gain of $62 million in 2021. Results in 2022 include a
$78 million charge from the settlement with the U.S. SEC, a $71 million non-cash gain from the reclassification to the
income statement of NKKTubes’s cumulative foreign exchange adjustments belonging to the shareholders due to the
cease of its operations and an $18 million gain from the sale of land in Canada after the relocation of the Prudential
facility. The gain in 2021 was mainly due to a $36 million recognition of fiscal credits in Brazil and the profit from the
sale of assets.
Financial results amounted to a loss of $6 million in 2022, compared to a gain of $23 million in 2021. 2022 financial loss
includes a loss of $10 million related to the change in fair value of certain financial instruments obtained in an
operation of settlement of trade receivables and a $30 million loss related to the transfer of Argentine sovereign bonds
paid as dividend from an Argentine subsidiary to its shareholders.
Equity in earnings of non-consolidated companies generated a gain of $209 million in 2022, compared to $513 million
in 2021. These results were mainly derived from our equity investment in Ternium (NYSE:TX). In 2022 they included $34
million impairment charges on our participations in the joint venture with Severstal ($15 million) and in Usiminas ($19
million).
Income tax charge amounted to $617 million in 2022, compared to $189 million in 2021, reflecting the improvement in
results in several subsidiaries.

Net sales of tubular products and services increased 24% to $5,994 million in 2021, compared to $4,844 million in 2020,
reflecting a 17% increase in volumes and a 6% increase in average selling prices. In North America sales increased 54%
as there was a recovery in volumes and prices throughout the region, led by the U.S. onshore market. In South America
sales increased 59% driven by a recovery in sales in Argentina and the Andean region partially offset by lower sales of
connectors in Brazil. In Europe sales increased 10% thanks to a strong growth in sales to the mechanical and
automotive sectors partially compensated by lower sales of OCTG products throughout the region. In the Middle East &
Africa sales declined 30% as sales in U.A.E. remained stable during the year while sales of OCTG and offshore line pipe
declined in the rest of the region. In Asia Pacific sales declined 21% due to lower sales of OCTG throughout the region.
Operating results from tubular products and services, amounted to a gain of $613 million in 2021, compared to a loss of
$616 million in 2020. Tubes operating income in 2021 is net of a $57 million impairment charge on NKKTubes fixed
assets and severance charges of $27 million, while in 2020 the operating loss includes an impairment charge of $582
million, accelerated depreciations and amortizations of $56 million and severance charges of $139 million. The
improvement in operating results was driven by the recovery in sales (volumes and prices), while an increase in raw
material and energy costs was partially offset by an improvement in industrial performance due to the increased levels
of activity and utilization of production capacity.

Net sales of other products and services increased 74% from $303 million in 2020 to $528 million in 2021, mainly due to
higher sales of energy and excess raw materials and sucker rods, as well as our new oilfield services business in
Argentina which offers hydraulic fracturing and coiled tubing services.
Operating results from other products and services, amounted to a gain of $95 million in 2021, compared to a loss of
$47 million in 2020. In 2020, Others operating income included an impairment charge of $40 million. The increase in
profitability is mainly due to the sucker rods business, our new oil services business and the sale of excess raw materials
and energy.
Selling, general and administrative expenses, or SG&A, amounted to $1,207 million (18.5% of net sales), compared to
$1,119 million (21.7%) in 2020. During 2021 SG&A includes $16 million of leaving indemnities, while in 2020 leaving
indemnities were $61 million. The 2021 increase in SG&A is mainly due to higher selling expenses, following the
increase in sales.

Impairment charge. In December 2021, as a result of the expected termination of our NKKTubes joint venture, we
recorded a $57 million impairment on its fixed assets. In 2020 we recorded an impairment charge of $622 million on
the carrying value of goodwill and other assets in the United States.
Other operating results amounted to a gain of $62 million in 2021, compared to a gain of $19 million in 2020. The gain
in 2021 is mainly due to a $36 million recognition of fiscal credits in Brazil and the profit from the sale of assets.
Financial results amounted to a gain of $23 million in 2021, compared to a loss of $65 million in 2020. The variation is
mainly explained by a $23 million improvement in net interest income, mainly due to interests from fiscal credits in
Brazil received in the second quarter, and a $64 million improvement in net foreign exchange results, mainly related to
the depreciation of the Euro, the Brazilian real and the Mexican peso in 2020. These results are to a large extent offset
by changes to our currency translation reserve.
Equity in earnings of non-consolidated companies generated a gain of $513 million in 2021, compared to $109 million
in 2020. These results were mainly derived from our equity investments in Ternium and Usiminas, and reflect the good
dynamics at the flat steel sector derived from record high steel prices.
Income tax charge amounted to $189 million in 2021, compared to $23 million in 2020, reflecting better results in
several subsidiaries following the increase in activity in 2021.
Net income amounted to $1,053 million in 2021, compared with a net loss of $642 million in 2020. The change in
results reflects the recovery in sales (volumes and prices) following the improvement in the operating environment,
while an increase in raw material and energy costs was partially offset by an improvement in industrial performance
due to the increased levels of activity and utilization of production capacity. Additionally, our results in 2021 were
boosted by an extraordinary contribution from our equity participations, mainly Ternium, reflecting the good dynamics
in the flat steel sector derived from record high steel prices, while 2020 was impacted by a $622 million impairment on
the carrying value of goodwill and other assets in the United States.

Our financing strategy aims to maintain adequate financial resources and access to additional liquidity. During 2022
cash flow provided by operating activities amounted to $1,167 million (including an increase in working capital of
$2,131 million), our capital expenditures amounted to $378 million, and we paid dividends amounting to $531 million.

Graphics
Annual Report 2022
72
At the end of the year, we had a net cash position
4
of $921 million, compared to $700 million at the beginning of the
year.
We believe that funds from operations, the availability of liquid financial assets and our access to external borrowing
through the financial markets will be sufficient to satisfy our working capital needs, to finance our planned capital
spending program as well as to service our debt in the future twelve months and to address short-term changes in
business conditions.
We have a conservative approach to the management of our liquidity, which consists of (i) cash and cash equivalents
(cash in banks, liquidity funds and investments with a maturity of less than three months at the date of purchase), and
(ii) other investments (fixed income securities, time deposits, and fund investments).
As of December 31, 2022, liquid financial assets as a whole (comprising cash and cash equivalents and other
investments) were 9% of total assets compared to 7% at the end of 2021.
We hold investments primarily in liquidity funds and variable or fixed-rate securities from investment grade issuers. We
hold our cash and cash equivalents primarily in U.S. dollars and in major financial centers. As of December 31, 2022,
and December 31, 2021, U.S. dollar denominated liquid assets represented 87% of total liquid financial assets.
Fiscal Year Ended December 31, 2022, Compared to Fiscal Year Ended December 31, 2021
Operating activities
Net cash provided by operations during 2022 was $1,167 million, compared to $119 million during 2021. This increase
was mainly attributable to the better results during the year, as net income for 2022 amounted to $2,549 million in
2022 and $1,053 million in 2021, partially offset by a higher increase in working capital, which amounted to $2,131
million in 2022, while in 2021 the increase in working capital amounted to $1,071 million. The annual variation in
working capital was mainly attributed to an increase of $1,330 million in inventories and $1,208 in trade receivables,
compared to an increase of $1,085 million in inventories and $356 million in trade receivables in 2021. For more
information on cash flow disclosures and changes to working capital, see note 29 “Cash flow disclosures” to our audited
consolidated financial statements included in this annual report.
Investing activities
Net cash used in investing activities was $164 million in 2022, compared to a net cash provided by investing activities of
$268 million in 2021. In 2022 we decreased our financial investments by $123 million compared to a decrease of $390
million in 2021, while capital expenditures amounted to $378 million in 2022 compared to $240 in 2021.
Financing activities
Net cash used in financing activities, including dividends paid, proceeds and repayments of borrowings and acquisitions
of non-controlling interests, was $178 million in 2022, compared to $648 million in 2021.
During 2022 we had net proceeds of borrowings of $417 million while in 2021 we had net repayments of borrowings of
$277 million.
Dividends paid during 2022 amounted to $531 million and during 2021 amounted to $319 million.
Our total liabilities to total assets ratio was 0.20:1 as of December 31, 2022 and 0.16:1 as of December 31, 2021.
Fiscal Year Ended December 31, 2021, Compared to Fiscal Year Ended December 31, 2020
Operating activities
Net cash provided by operations during 2021 was $119 million, compared to $1,520 million during 2020. This decrease
was mainly attributable to a $1,071 million increase in working capital in 2021, while in 2020 the decrease in working
capital amounted to $1,055 million, offset by an impairment charge of $622 million in 2020. The annual variation in
working capital was mainly attributed to an increase of $1,085 million in inventories related to the recovery in activity,

Trend Information
Principal Factors Affecting Oil and Gas Prices and Demand for Steel Pipes from the Global Oil and Gas Industry
Sales to the oil and gas industry worldwide represent a high percentage of our total sales, and demand for steel pipes
from the global oil and gas industry is a significant factor affecting the general level of volumes and prices for our
products. Downward pressures on oil and gas prices usually result in lower oil and gas drilling activity and investment
throughout the oil and gas industry with consequently lower demand for our steel pipe products and, in some
circumstances, upward pressures can result in higher demand from our oil and gas customers.
Whereas oil prices are similar in most parts of the world because oil is a fully tradable commodity, gas prices are
influenced by regional factors. In North America, where gas production is extensively developed and there is an
extensive regional pipeline system, these factors include available gas storage capacity and seasonal weather patterns,
particularly winter temperatures in the United States. LNG prices were traditionally established in relation to
international oil prices, particularly in the largest LNG markets in Asia. However, as the market for LNG becomes more
global and the United States becomes a relevant source of LNG, LNG prices are now being set increasingly in relation to
gas prices prevailing at regional gas hubs. In 2022, spot LNG prices completely decoupled from oil prices as pipeline gas
imports to Europe from Russia were substantially reduced consequent to the Russian invasion of Ukraine and European
countries dramatically increased imports of LNG to replace Russian gas.
International oil prices depend on diverse factors. On the supply side, major oil-and-gas-producing nations and
companies have frequently collaborated to balance the supply (and thus the price) of oil in the international markets. A
major vehicle for this collaboration has been OPEC, and more recently what has become known as OPEC+, which
5
Net cash position is a non-IFRS alternative performance measureplease see Exhibit 3 for more information on this measure.

Graphics
Annual Report 2022
75
includes OPEC members, plus Russia and certain other countries. Many of our customers are state-owned companies in
member countries of OPEC and OPEC+. Another factor that has affected the international price level of oil is the
political and socioeconomic conditions of oil-producing countries, such as Libya, Nigeria and Venezuela and the
persistence of geo-political and armed conflicts, such as the recent Ukraine-Russia armed conflict, and conflicts
affecting the Middle East region, which is home to a substantial proportion of the world’s known oil reserves. See “Key
Information Risk Factors Risks Relating to Our Business and Industry The Russia-Ukraine armed conflict may
adversely affect our operations”.
On the demand side, economic conditions and the level of oil inventories have traditionally played a role in oil prices
and will continue to do so. Increasingly, however, the rate of substitution of oil and gas by alternative, cleaner fuel
sources such as renewables, as well as policies adopted by governments and financing entities worldwide to accelerate
the energy transition and by oil and gas companies to adapt their strategies to the energy transition, will also play a
significant role in oil prices.
Another factor affecting oil and gas prices has been the ability of producers in the United States and Canada to rapidly
increase production from their reserves of tight oil and shale gas in response to changes in market conditions.
Production from U.S. tight oil reserves has grown in recent years to represent over 10% of global liquids production,
and production from shale gas plays has converted the United States into a net exporter of natural gas and a major
player in the LNG market.
Following three years of relatively stable oil prices of around $100 per barrel, prices started to decline in the middle of
2014 as the rate of U.S. production increase began to exceed the increase in global demand and OPEC confirmed at its
November 2014 meeting that it would not cut production to balance demand. Consequently, prices reached levels
below $30 per barrel in January 2016. Prices then recovered to around $80 per barrel during 2018 once OPEC and other
producers agreed to cut production levels to accelerate the market rebalancing process. By this time, OPEC and other
producers had lifted their production cuts and U.S. oil production was increasing at a rate greater than the increase in
global demand. Oil prices declined 40% in the fourth quarter of 2018 before partially recovering in 2019. In 2020, the
COVID-19 pandemic caused a sudden and precipitous drop in global oil demand and oil prices collapsed even entering
negative territory at one point. Since then, prices have recovered above their pre-pandemic level with the recovery in
demand and actions by OPEC member countries and other producers to cut and then gradually increase production
levels. In addition, energy and commodity prices spiked upwards at the onset of the armed conflict involving Russia and
Ukraine although they have subsequently fallen back to a large extent. LNG prices, fell back at the end of 2022 and
beginning of 2023 reflecting unusually warm winter weather conditions and reduced industrial demand in Europe
which resulted in far lower drawdowns from storage than is customary for this period of the year. For more information
on the impact of the armed conflict in Ukraine, see “Key Information Risk Factors Risks Relating to Our Business and
Industry The Russia-Ukraine armed conflict may adversely affect our operations”.
The 2014 collapse of oil prices, led oil and gas operators to substantially reduce their exploration and production
investments. This, in turn, resulted in a severe contraction in demand and pressure on pricing for steel pipes used in oil
and gas drilling and associated operations. During 2017, however, oil and gas operators in North America, who were
very successful in reducing production costs and increasing drilling efficiencies in their shale plays, increased
investments in response to more favorable market conditions, and U.S. operators continued to do so in 2018. However,
from 2019, operators have reduced investment in the shales as they reacted to financial market pressures to achieve
positive cash flow returns. With the collapse of oil prices in March 2020 and continuing pressure from financial markets
to generate positive free cash flows
6
, oil and gas operators around the world made further substantial reductions in
their exploration and production investments, to a level around 40% of the average of the 2012-2014 period. Although
investments have been increasing again, global spending on exploration and production remained well below pre-
pandemic levels during 2022.
Since the development of the prolific Marcellus shale gas play, North American gas prices have remained at low levels
compared to previous decades and relative to other major gas-consuming regions and global LNG prices. For several
years, production increases, primarily from productive shale gas deposits, have exceeded regional demand increases,
reducing the need for imports, to the extent that, in 2017, the United States became a net exporter of natural gas. Low
prices have encouraged investment in gas consuming industrial facilities and LNG export facilities as well as switching
from coal to gas for electric power production, particularly with the adoption of new regulations which could force the
retirement of older coal-based generating units. With continuing investments in LNG export facilities, the United States
6

Graphics
Annual Report 2022
76
has become a major global LNG exporter, and, over the past two years, has brought more new LNG capacity to the
international market than any other producer.
Until the Russian invasion of Ukraine LNG prices used to reflect supply and demand conditions in Asia, the major LNG-
consuming region, although demand had been increasing in regions like Europe, which imports LNG to supplement its
traditional pipeline imports from Russia and other neighboring gas-producing regions, and South America, which
imports LNG in its winter season and to supplement hydroelectric energy when rainfall is low. In 2022, however, Europe
became a major competitor to Asia in the LNG market as it sought to replace Russian pipeline gas at almost any cost. As
Europe phases out imports of pipeline gas from Russia, demand for LNG in Europe is likely to continue to grow in the
coming years, and this is changing the price dynamics of the industry. Demand and prices are likely to remain high until
a new wave of capacity in Qatar and North America can be brought on stream from 2025. Consumption, though not
necessarily prices, will continue to show seasonal fluctuations, increasing in the North Asian winter period and declining
in the summer months. The efforts to fill European storage capacity and increase import capacity has, however,
increased price volatility.
U.S. natural gas prices increased during 2021, reaching $6 per million BTU as LNG export capacity came on stream and
demand increased. In late 2022 and early 2023, prices declined to a level of $2-3 per million BTU in February 2023 as
LNG export demand was capped by capacity limitations and the temporary shutdown of a facility while domestic
demand during the winter heating season was lower than usual.
Drilling activity in the United States and Canada, following several years of high activity, fell sharply through 2015 and
the first half of 2016 before beginning a recovery which ended at the end of 2018. Drilling activity declined throughout
2019 in response to a fall in oil prices at the end of 2018 and financial market pressures to produce positive cash flow
returns. This decline turned into a collapse with the onset of the COVID-19 pandemic in 2020. Since then, there has
been a steady recovery through 2021 and 2022. Production levels today are higher than before the 2014 collapse of oil
prices but rig counts are much lower, reflecting the strong productivity gains made by the U.S. oil and gas drilling
industry. In the rest of the world, drilling activity began to decline in the second half of 2014, continued to decline
during 2015, 2016 and 2017 before a gradual recovery in the second half of 2018 and 2019. Following the onset of the
COVID-19 pandemic in 2020, drilling activity in the Eastern Hemisphere declined more slowly and later than in Latin
America but then recovered later and more gradually than in Latin America.
Prior to the 2014 downturn in oil prices, a growing proportion of exploration and production spending by oil and gas
companies had been directed at offshore, deep drilling and non-conventional drilling operations in which high-value
tubular products, including special steel grades and premium connections, are usually specified. The success, however,
of shale drilling operators, with their inherently short investment cycles, in adapting to lower oil and gas prices and
increasing production, led to a slowdown in new developments of complex offshore projects with long investment lead
times in a context of low and more volatile oil prices, consequently affecting the level of product differentiation. More
recently, however, offshore drilling activity has increased again as exploration has continued and cost-competitive
developments, like those in Brazil, Guyana, and sub-Saharan Africa, are being sanctioned and developed.
In addition, the increasing cost competitiveness and use of alternative renewable sources of energy will limit growth in
demand for oil and gas and put downward pressure on oil and gas prices in the longer term. This trend will accelerate if
carbon taxes or carbon pricing instruments resulting in high prices for carbon emissions, or other regulations aimed at
reducing the use of fossil fuels, are implemented around the world. There has been a substantial increase in the
number of commitments to reduce carbon emissions from governments and public companies, including those
operating in the oil and gas industry, and increased calls on governments and financial entities to introduce regulations
and policies to accelerate the energy transition away from fossil fuels to cleaner sources of energy. Major oil and gas
companies have been adapting their strategies to address the energy transition and some are even setting out
commitments to significantly reduce production as early as 2030. For more information on climate change regulations,
see “Key Information Risk Factors Risks Relating to Our Business and Industry - Climate change legislation and
increasing regulatory requirements aimed at transitioning to a lower-carbon economy may reduce demand for our
products and services and result in unexpected capital expenditures and costs, and negatively affect our reputation”.
On the other hand, we expect that the energy transition will create new markets for the use of our products and
services including in the transportation and storage of hydrogen and for carbon capture and sequestration systems. We
constantly monitor the evolution of the strategies of our main customers and scenarios for future energy demand,
considering the global objectives for addressing climate change through the reduction of carbon emissions and national
objectives to achieve carbon-neutrality. We also assess the market outlook for our products with reference to the
different scenarios for oil and gas demand published by our customers, international agencies such as the IEA and

Graphics

expert energy market consultancies such as Rystad, with particular reference to scenarios that are consistent with the
goals of the Paris Agreement and those focused on technological change and the rate of adoption of new technologies.
These assessments are used as fundamental input for evaluating our business strategy and how to address the risks and
opportunities arising from climate change.

Critical Accounting Estimates
This discussion and analysis of our financial condition and results of operations is based on our audited consolidated
financial statements, which have been prepared in accordance with IFRS. IFRS differs in certain significant aspects from
U.S. GAAP.
The preparation of our audited consolidated financial statements and related disclosures in conformity with IFRS
requires us to make estimates and assumptions that might affect the reported amounts of assets and liabilities, the
disclosure of contingent liabilities and the reported amounts of revenue and expenses. Management evaluates its
accounting estimates and assumptions, including those related to impairment of goodwill and long-lived assets;
impairment in investment in associates; income taxes; obsolescence of inventory; contingencies; allowance for trade
receivables; post-employment and other long-term benefits; business combinations; useful lives of property, plant and
equipment and other long-lived assets; fair value estimation of certain financial instruments and property title
ownership restriction, and revises them when appropriate. Management bases its estimates on historical experience
and on various other assumptions it believes to be reasonable under the circumstances. These estimates form the basis
for making judgments about the carrying values of assets and liabilities that are not readily apparent from other
sources. Although management believes that these estimates and assumptions are reasonable, they are based upon
information available at the time they are made. Actual results may differ significantly from these estimates under
different assumptions or conditions. For more information see II. Accounting Policiesto our consolidated financial
statements included in this annual report.

Directors and Senior Management
Board of Directors
Management of the Company is vested in a board of directors with the broadest power to act on behalf of the
Company and accomplish or authorize all acts and transactions of management and disposal that are within its
corporate purpose and not specifically reserved in the articles of association or by applicable law to the general
shareholders’ meeting. The Company’s articles of association provide for a board of directors consisting of a minimum
of three and a maximum of fifteen directors; however, for as long as the Company’s shares are listed on at least one
regulated market, the minimum number of directors must be five. The Company’s current board of directors is
composed of eleven directors.
The board of directors is required to meet as often as required by the interests of the Company and at least four times
per year. Board of directors meetings can be validly held by means of teleconference call, video conference or any
other means genuinely allowing for the participation, interaction and intercommunication of the attending directors.
Written decisions, signed by all the directors, are proper and valid as though they had been taken at a meeting of the
board of directors duly convened and held. In 2022, the Company’s board of directors met nine times and adopted four
unanimous written resolutions. A majority of the members of the board of directors in office present or represented at
the board of directors’ meeting constitutes a quorum, and resolutions may be adopted by the vote of a majority of the
directors present or represented. In case of a tie, the chairman is entitled to cast the deciding vote.
Directors are elected at the annual ordinary general shareholders’ meeting to serve one-year renewable terms, as
determined by the general shareholders’ meeting. The general shareholders’ meeting also determines the number of
directors that will constitute the board and their compensation. The general shareholders’ meeting may dismiss all or
any one member of the board of directors at any time, with or without cause, by resolution passed by a simple majority
vote, irrespective of the number of shares represented at the meeting.
The Company’s articles of association provide that the board of directors of the Company may within the limits of
applicable law, (a) delegate to one or more persons, whether or not members of the board of directors, the powers
necessary to carry out its decisions and to provide day-to-day management (except for approval of material
transactions with related parties, which may not be delegated and shall be approved by the board of directors prior
opinion of the audit committee), (b) confer to one or more persons, whether or not members of the board of directors
the powers deemed to be appropriate for the general technical, administrative and commercial management of the
Company, (c) constitute an audit committee formed by directors, determining its function and authority, and (d)
constitute any other committee, whose members may or may not be members of the board of directors and determine
their functions and authority. On May 3, 2022, the board of directors appointed Tenaris’s chief executive officer as
administrateur délégué and delegated to him the power to manage the Company’s affairs within the ordinary course of
business, to the full extent permitted by Luxembourg law, to direct and supervise the business activities of the
Company’s subsidiaries and to represent the Company in relation to such matters.
On May 3, 2022, the Company’s annual general shareholders’ meeting appointed Ms. Maria Novales-Flamarique to the
board of directors and re-appointed Mr. Simon Ayat, Mr. Roberto Bonatti, Mr. Carlos Condorelli, Mr. Germán Curá, Mr.
Roberto Monti, Mr. Gianfelice Mario Rocca, Mr. Paolo Rocca, Mr. Jaime José Serra Puche, Ms. Monica Tiuba and Mr.
Guillermo Vogel, as members of its board of directors, each board member to serve until the next annual shareholders
meeting that will be convened to decide on the Company’s 2022 annual accounts. The board of directors subsequently
reappointed Paolo Rocca as board chairman and Tenaris’s chief executive officer and Guillermo Vogel and Germán Cu
as vice-chairmen of the board.

Directors’ Liability
Each director must act in the interest of the Company, and in accordance with applicable laws, regulations, and the
Company’s articles of association. Directors are also bound by a general duty of care owed to the Company.
Under the Luxembourg law of August 10, 1915, on commercial companies, as amended (the “Luxembourg Company
Law”), directors may be liable to the Company in accordance with general law for the execution of their mandate and
for any misconduct in the management of the Company’s affairs. Directors are jointly and severally liable towards
either the Company or any third parties from damages resulting from the violation of the Luxembourg Company Law or
the Company’s articles of association. Directors shall be discharged from such liability in the case of a violation to which
they were not a party provided no misconduct is attributable to them and such violation has been reported to the first
general meeting of shareholders after they have acquired knowledge thereof.
Causes of action against directors for damages may be initiated by the Company upon a resolution of the general
shareholders’ meeting passed by a simple majority vote, irrespective of the number of shares represented at the
meeting. Causes of action against directors who misappropriate corporate assets or commit a breach of trust may be
brought by any shareholder for personal losses different from those of the Company.
An action may also be brought against the directors on behalf of the Company by shareholders who, at the general
meeting which decided to discharge such directors or members, owned voting securities representing at least ten
percent of the votes attaching to all such securities.
It is customary in Luxembourg that the shareholders expressly discharge the members of the board of directors from
any liability arising out of or in connection with the exercise of their mandate when approving the annual accounts of
the Company at the annual general shareholders meeting. However, any such discharge will not release the directors
from liability for any damage caused by unrevealed acts of mismanagement or unrevealed breaches of the Luxembourg
Company Law or the Company’s articles of association, nor will it release directors from liability for any personal loss of
the shareholders independent and separate from losses suffered by the Company due to a breach either revealed or
unrevealed of the Luxembourg Company Law or the Company’s articles of association.
Under Luxembourg law, unless the decision of the board of directors relates to ordinary business entered into under
normal conditions, any director having a direct or indirect financial interest conflicting with that of the Company in a
transaction which has to be considered by the board of directors, must advise the board thereof and cause a record of
her/his statement to be included in the minutes of the meeting and may not take part in the deliberations. At the next
following general meeting, before any other resolution is put to vote, a special report must be made on any
transactions in which any of the directors may have had an interest conflicting with that of the Company.
Auditors
The Company’s articles of association require the appointment of an independent audit firm in accordance with
applicable law. The primary responsibility of the auditor is to audit the Company’s annual accounts and consolidated
financial statements and to submit a report on the accounts to shareholders at the annual shareholders’ meeting. In
accordance with applicable law, auditors are chosen from among the members of the Luxembourg Institute of
Independent Auditors (Institut des réviseurs d’entreprises).
Auditors are appointed by the general shareholders’ meeting upon recommendation from the Company’s audit
committee through a resolution passed by a simple majority vote, irrespective of the number of shares represented at
the meeting, to serve one-year renewable terms. Auditors may be dismissed for reasonable cause by the general
shareholders’ meeting at any time. Luxembourg law does not allow directors to serve concurrently as external auditors.
As part of their duties, auditors report directly to the audit committee.
Pursuant to its charter, the Company’s audit committee is responsible for, among other things, the oversight of the
independence and performance of the Company’s external auditors. The audit committee is also responsible to
consider and make recommendations to the board of directors, to be put to shareholders for approval at the annual
general meeting of shareholders, regarding the appointment, re-appointment or removal of the Company’s external
auditors. In addition, the audit committee is responsible to review the appropriateness and provision of permitted non-
audit fees and to review and approve any fees (whether for audit, audit-related and non-audit services) payable to the
Company’s external auditors. On a yearly basis, in the performance of its functions, the audit committee considers the
appointment of the Company’s external auditors and reviews, together with management and the external auditor, the

Graphics
Annual Report 2022
82
audit plan, audit related services and other non-audit services. The audit committee requests the board of directors to
submit the audit committee’s recommendation for the appointment of the Company’s external auditor for each fiscal
year and the payment of applicable fees, for final approval by the general shareholders’ meeting. The general
shareholders’ meeting regularly approves audit fees and authorizes the audit committee to approve any increase or
reallocation of such audit fees as may be necessary, appropriate or desirable under the circumstances. No services
outside the scope of the audit committee’s approval can be undertaken by the external auditor.
The shareholders’ meeting held on May 3, 2022, re-appointed PwC Luxembourg as the Company’s independent
approved statutory auditor for the fiscal year ended December 31, 2022. At the next annual general shareholders’
meeting scheduled to be held on May 3, 2023, it will be proposed that PwC Luxembourg be re-appointed as the
Company’s independent approved statutory auditors for the fiscal year ending December 31, 2023, and that Ernst &
Young (“EY”) be appointed as the Company’s external auditors for the fiscal year ending December 31, 2024, following
the completion of a tender process for the selection of a replacement audit firm for the year 2024, in response to
applicable EU and Luxembourg mandatory auditor rotation rules.

Compensation
The compensation payable to the members of the Company’s board of directors for the performance of their services

the year 2022 amounts to $9.5 million, of which $3 million corresponds to fixed compensation and $6.5 million
corresponds to variable compensation. No long-term incentive or pension plan is awarded to the chief executive
officer.
The aggregate cash compensation paid to all directors and senior managers of the Company for the year 2022

The Luxembourg Law of August 1, 2019 (amending the Luxembourg Law of May 24, 2011) (the “Shareholders’ Rights
Law”) on the exercise of certain rights of shareholders in general meetings of listed companies, which transposes EU
Directive 2017/828 of the European Parliament and of the Council of May 17, 2017 (amending Directive 2007/36/EC)
regarding the encouragement of long-term shareholder engagement in listed companies within the Member States of
the European Union, requires EU listed companies to adopt a Compensation Policy setting forth the principles and
guidelines for purposes of determining the compensation payable to the members of the Company’s board of directors
and the managing director or chief executive officer and annual Compensation Reports describing the annual
compensation paid to directors and the chief executive officer for the performance of their duties.
The Company’s board of directors approved, at its meeting held on April 29, 2020, the Compensation Policy of the
Company, which was submitted to an advisory non-binding vote at the shareholders meeting held on June 2, 2020, and
approved by majority vote. The Compensation Policy is available on the Company’s website and will be submitted to
the non-binding vote of the shareholders every four years, to the extent required by Luxembourg law, or in the event of
a material amendment thereto.
In addition, on March 31, 2023, the Company’s board of directors approved the 2022 Compensation Report, which is
available on the Company’s website and will be submitted to the non-binding vote of the shareholders at the next

Board Practices
Audit Committee
Pursuant to the Company’s articles of association, as supplemented by the audit committee’s charter, for as long as the
Company’s shares are listed on at least one regulated market, the Company must have an audit committee composed
of at least three members, the majority of whom must qualify as independent directors, provided, however, that the
composition and membership of the audit committee shall satisfy such requirements as are applicable to, and
mandatory for, audit committees of issuers such as the Company under any law, rule or regulation applicable to the
Company (including, without limitation, the applicable laws, rules and regulations of such regulated market or markets).
Under the Company’s articles of association, an independent director is a director who:
is not and has not been employed by us or our subsidiaries in an executive capacity for the preceding five years;
is not a person that controls us, directly or indirectly, and is not a member of the board of directors of a
company controlling us, directly or indirectly;
does not have (and is not affiliated with a company or a firm that has) a significant business relationship with us,
our subsidiaries or our controlling shareholder;
is not and has not been affiliated with or employed by a present or former auditor of us, our subsidiaries or our
controlling shareholder for the preceding five years; and
is not a spouse, parent, sibling or relative up to the third degree of any of the above persons.
The audit committee of the Company’s board of directors currently consists of four members: Mr. Simon Ayat, Mr.
Roberto Monti, Mr. Jaime José Serra Puche and Ms. Monica Tiuba, who were appointed to the audit committee by the
Company’s board of directors on May 3, 2022. As of the date of this annual report, all members of the audit committee
qualify as independent directors both for purposes of the Exchange Act Rule 10A-3(b)(1), and under the Company’s
articles of association. The board of directors of the Company has determined that Ms. Tiuba qualifies asaudit
committee financial expert” under applicable SEC rules and has competence in accounting or auditing matters, as
required by applicable Luxembourg law. In addition, the membership of the audit committee as a whole has sufficient
relevant knowledge of the business and financial experience to properly discharge its functions.
The audit committee operates under a charter amended and restated by the board of directors on October 8, 2021. The
audit committee assists the board of directors in its oversight responsibilities relating to (i) the integrity of the
Company’s financial statements; (ii) the effectiveness of the Company’s systems of internal control, risk management
and internal audit over financial reporting; and (iii) the independence and performance of the Company’s external
auditors. The audit committee also performs other duties entrusted to it by the Company’s board of directors or
required to be performed by it under applicable laws and regulations.
In addition, the audit committee is required to review and, where applicable, approve material transactions between
the Company or its subsidiaries and related parties, as provided in the Company’s articles of association, or as may be
required by any law, rule or regulation applicable to the Company, in order to determine whether their terms are
consistent with the interests of the Company and all its shareholders and are consistent with market conditions or are
otherwise fair to the Company and its subsidiaries. The Company has adopted a Related Party Transactions Policy and
Procedure setting forth the revised, updated and consolidated guidelines and processes through which the Company
identifies, approves and manages related party transactions, seeking to assure transparency and substantial and
procedural fairness of such transactions, as well as compliance with the provisions in the Company’s articles of
association and the audit committee charter relating to transactions with related parties, Luxembourg rules relating to
the approval and disclosure of material related party transactions, and Section 314.00 of the NYSE Listed Company
Manual.
Under the Company’s articles of association, as supplemented by the Related Party Transactions Policy and Procedure,
a “related party” is any of the following persons: (i) any affiliate of the Company; (ii) any entity in which a controlling
person owns a substantial interest or over which a controlling person can exercise significant influence; (iii) any
unconsolidated entity in which the Company has significant influence; (iv) any entity or individual having significant
influence over the Company, or a close family member of any such individual; (v) any individual or entity that is the
beneficial owner of five percent (5%) or more of the shares of the Company, including through the ownership of any

Graphics
Annual Report 2022
86
securities representing shares of the Company; (vi) any director or executive officer of any of the controlling persons,
the Company or any of the subsidiaries, or a close family member of any such director or executive officer; (vii) any
entity in which a substantial interest in the voting power is owned, directly or indirectly, by any person described in (iv),
(v) or (vi) above or over which such a person is able to exercise significant influence; or (viii) any entity that has a
member of key management in common with the Company or any of its subsidiaries (provided that key management
personnel includes persons having authority and responsibility for planning, directing and controlling the activities of an
entity, including directors and executive officers and close family members of any such individuals).
With respect to the materiality threshold for review and approval of related party transactions, the Company’s articles
of association, as supplemented by the audit committee’s charter and the Related Party Transactions Policy and
Procedure, provide that the following related party transactions, which are qualified as Level 1 related party
transactions, are subject to review by the audit committee, which shall make a recommendation to the board of
directors as to either reject or approve the proposed related party transaction:
any transaction between the Company or its subsidiaries with related parties (i) with an individual value equal to or
greater than $10 million, or its equivalent in other currencies, or (ii) with an individual value lower than $10 million,
or its equivalent in other currencies, when the aggregate sum reflected in the financial statements of the four fiscal
quarters preceding the date of determination of any series of transactions for such lower value that can be deemed
to be parts of a unique or single transaction (but excluding any transactions that were reviewed and approved by
Company’s audit committee or board of directors, as applicable, or the independent members of the board of
directors of any of its subsidiaries) exceeds 1.5% of the Company’s consolidated net sales made in the fiscal year
preceding the year on which the determination is made; and
any corporate reorganization transaction (including a merger, spin-off or bulk transfer of a business) affecting the
Company or any of its subsidiaries for the benefit of, or involving, a related party.
In addition, any related party transaction that does not qualify as a Level 1 related party transaction, but which has an
individual value equal to or higher than $5 million (which is the value threshold determined by management to be
material to the Company for disclosure purposes under “Related Parties Transactions” of this annual report), qualifies
as a “Level 2” related party transaction and must be reviewed by the audit committee for purposes of making a
determination as to whether any conflicts of interest exist and whether the proposed related party transaction is
consistent with the interests of the Company and all shareholders, in order to either reject or approve the proposed
transaction. Any related party transaction that is for less than such value qualifies as a “Level 3” related party
transaction and is reviewed by the Company’s related-party transaction unit, the area within the Company responsible
for centralizing and compiling the information relating to all related party transactions and performing the review,
assessment and other procedures contemplated in the Related Party Transactions Policy and Procedure.
The audit committee has the power (to the maximum extent permitted by applicable laws) to request that the
Company or relevant subsidiary promptly provide all information necessary for the audit committee to assess the
material transactions with related parties that it is required to review. In no event may any proposed related party
transaction be entered into or otherwise be given effect unless it has been reviewed and approved in accordance with
the Related Party Transactions Policy and Procedure. Any executed transaction that has not been duly reviewed and
approved must be promptly submitted for review in accordance with applicable procedures and, if determined
appropriate, must be ratified; if the transaction is not ratified, it must be modified to make it acceptable for ratification
or it must otherwise be immediately discontinued or rescinded.
The audit committee has the authority to conduct any investigation appropriate to the fulfillment of its responsibilities
and has direct access to the Company’s external auditors as well as anyone in the Company and, subject to applicable
laws and regulations, its subsidiaries. In addition, the audit committee may engage, at the Company’s expense,
independent counsel and other internal or external advisors to review, investigate or otherwise advise on, any matter
as the committee may determine to be necessary to carry out its purposes and responsibilities.
In addition, the Company has established a management-level Critical Risk Committee (“CRC”) that assists the
Company’s board of directors, the audit committee and the chief executive officer in connection with the monitoring,
assessment and review of risks to which Tenaris is exposed and in the oversight of the risk management framework and
processes, with a focus on critical risks (including accidents, cybersecurity, commercial execution, environmental,
health and safety and regulatory risks), the development of mitigating actions, and the monitoring of action plans. The
CRC operates under a Critical Risk Management charter approved by the board of directors on November 1, 2017,
which sets forth the roles, composition and responsibilities of the CRC. The CRC assists
the board of directors, the audit committee and the chief executive officer with the oversight of the risks to which

Graphics

Tenaris is exposed and monitors the risk management process, including risk mapping, mitigation and prevention, with
a focus on critical risks. The CRC periodically reports to the board of directors, the audit committee and the chief
executive officer on its activities.

The ramp-up of activity, particularly in our U.S., Canadian and Argentine operations, following the recovery in demand,
has led to a substantial increase in our headcount during the year, with shop-floor employees and technical leaders
increasing by more than 2,000 from December 2021 to December 2022, and professional employees increasing by
approximately 400 over the same period of time. We reinforced health, safety and environment training to ensure all
employees receive training to minimize incidents and accidents while keeping quality and productivity levels high on
the production lines.
Our headcount decreased in Japan and Brazil. In Japan, the reduction was caused by the termination of the joint
venture agreement with JFE and cease of NKKTubes’ operations in Japan. In Brazil, headcount decreased as a result of
the discontinuation of Confab Equipamentos activities in its industrial facility in Moreira César, Pindamonhangaba, São
Paulo, Brazil.
Approximately two-thirds of our employees are unionized. In all countries where we have presence, we operate in
compliance with applicable rules and regulations. We forge our relations with the unions based on the premise of an
open dialogue and a rich interchange of proposals.
Tenaris is committed to leading with care, providing a flexible and agile working environment that encourages health,
safety and wellbeing, accountability, inclusion and trust, allowing employees to develop their skills and careers while
contributing to our goals.
In terms of human resources our goals are:
to foster trust and empower employees to manage and promote change and innovation, providing them with
the training and technological resources to succeed;
to embed sustainability values through transparent and effective processes, helping employees shape their
professional careers;
to encourage continuous learning and feedback through concrete tools; and
to respect and promote diversity and inclusion in all its forms, focused on gender, age, culture and
background.
The Company’s Code of Conduct prohibits unlawful discrimination in employment relationships, granting all people the
right to apply for a position in Tenaris, or to be considered for a new position based on merit, without arbitrary
discrimination. The Company’s Human Resources Policy champions equal opportunities by ensuring that hiring,
promotion, transfer, notice periods, dialogue, rights and protection, as well as other employment decisions are taken
without regard for race, color, religious belief, gender, age, disability, national origin or sexual orientation.

Compensation and remuneration are based on each person’s duties, personal performance, competence and behavior.
Tenaris pursues a policy of inclusive corporate culture and leadership, recognizing the range of benefits brought by
embracing diversity in all its aspects, from gender to nationality and age. Specifically, we are making headway in our
drive to improve the gender balance, in the knowledge that tackling the male-dominated traditions prevalent in the
steel industry will contribute positively to our performance culture.

Financial Information
Consolidated Statements and Other Financial Information
See “Financial Statements”.
Legal Proceedings
Tenaris is from time to time subject to various claims, lawsuits and other legal proceedings, including customer,
employee, tax and environmental-related claims, in which third parties are seeking payment for alleged damages,
reimbursement for losses, or indemnity. Management with the assistance of legal counsel periodically reviews the
status of each significant matter and assesses potential financial exposure.
Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are
subject to substantial uncertainties and, therefore, the probability of loss and an estimation of damages are difficult to
ascertain. Accordingly, with respect to a large portion of such claims, lawsuits and other legal proceedings, the
Company is unable to make a reliable estimate of the expected financial effect that will result from ultimate resolution
of the proceeding. In those cases, the Company has not accrued a provision for the potential outcome of these cases.
If a potential loss from a claim, lawsuit or other proceeding is considered probable and the amount can be reasonably
estimated, a provision is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be
incurred based on information available to management as of the date of preparation of the financial statements and
take into consideration litigation and settlement strategies. In a limited number of ongoing cases, the Company was
able to make a reliable estimate of the expected loss or range of probable loss and, depending on the likelihood of
occurrence, in some of such cases has accrued a provision for such loss but believes that publication of this information
on a case-by-case basis would seriously prejudice the Companys position in the ongoing legal proceedings or in any
related settlement discussions. Accordingly, in these cases, the Company has disclosed information with respect to the
nature of the contingency but has not disclosed its estimate of the range of potential loss.
The Company believes that the aggregate provisions recorded for potential losses in its consolidated financial
statements (see notes 23 “Non-current allowances and provisionsand 24 Current allowances and provisions” to our
audited consolidated financial statements included in this annual report) are adequate based upon currently available
information. However, if management’s estimates prove incorrect, current reserves could be inadequate and the
Company could incur a charge to earnings which could have a material adverse effect on its results of operations,
financial condition, net worth and cash flows.
Material Legal Proceedings
Below is a summary description of Tenaris’s material legal proceedings for the year ended December 31, 2022. In
addition, Tenaris is subject to other legal proceedings, none of which is believed to be material.
CSN claims relating to the January 2012 acquisition of Usiminas
Confab, a Brazilian subsidiary of the Company, is one of the defendants in a lawsuit filed in Brazil by Companhia
Siderúrgica Nacional (“CSN”) and various entities affiliated with CSN against Confab and several Ternium subsidiaries
that acquired a participation in Usiminas’ control group in January 2012.
The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-
along tender offer to all non-controlling holders of Usiminas’ ordinary shares for a price per share equal to 80% of the
price per share paid in such acquisition, or BRL28.8, and seeks an order to compel the acquirers to launch an offer at
that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not
belonging to Usiminas’ control group, and Confab would have a 17.9% share in that offer.
On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of
appeals maintained the understanding of the first instance court. On August 18, 2017, CSN filed an appeal to the
Superior Court of Justice seeking the review and reversal of the decision issued by the Court of Appeals. On March 5,
2018, the court of appeals ruled that CSN’s appeal did not meet the requirements for submission to the Superior Court
of Justice and rejected the appeal. On May 8, 2018, CSN appealed against such ruling and on January 22, 2019, the
court of appeals rejected it and ordered that the case be submitted to the Superior Court of Justice. On September 10,
2019, the Superior Court of Justice declared CSN’s appeal admissible. On March 7, 2023, the Superior Court of Justice,

Graphics
Annual Report 2022
93
by majority vote, rejected CSN’s appeal. Plaintiffs may still appeal against the Superior Court of Justice’s decision. At
this time, the Company cannot predict whether CSN will appeal against the decision and, if appealed, the ultimate
resolution of the matter.
The Company continues to believe that all of CSN’s claims and allegations are groundless and without merit, as
confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator
(“CVM”) in February 2012 and December 2016, the first and second instance court decisions and the March 2023
decision of the Superior Court of Justice referred to above.
Veracel celulose accident litigation
On September 21, 2007, an accident occurred in the premises of Veracel Celulose S.A. (“Veracel”) in connection with a
rupture in one of the tanks used in an evaporation system manufactured by Confab. The Veracel accident allegedly
resulted in material damages to Veracel. Itaú Seguros S.A. (“Itaú”), Veracel’s insurer at the time of the Veracel accident
and then replaced by Chubb Seguros Brasil S/A (“Chubb”), initiated a lawsuit against Confab seeking reimbursement of
damages paid to Veracel in connection with the Veracel accident. Veracel initiated a second lawsuit against Confab
seeking reimbursement of the amount paid as insurance deductible with respect to the Veracel accident and other
amounts not covered by insurance. Itaú and Veracel claimed that the Veracel accident was caused by failures and
defects attributable to the evaporation system manufactured by Confab. Confab believes that the Veracel accident was
caused by the improper handling by Veracel’s personnel of the equipment supplied by Confab in violation of Confab’s
instructions. The two lawsuits were consolidated and are considered by the 6th Civil Court of São Caetano do Sul.
However, each lawsuit will be adjudicated separately.
On September 28, 2018, Confab and Chubb entered into a settlement agreement pursuant to which on October 9,
2018, Confab paid an amount of approximately $3.5 million to Chubb, without assuming any liability for the accident or
the claim.
On October 10, 2018, Confab was notified that the court had issued rulings for both lawsuits. Both decisions were
unfavorable to Confab:
With respect to Chubb’s claim, the court subsequently homologated the above-mentioned settlement and,
accordingly, the claim was finalized.
With respect to Veracel’s claim, Confab was ordered to pay the insurance deductible and other concepts not
covered by insurance, currently estimated to amount to BRL91.9 million (approximately $17.4 million) including
interest, fees and expenses. Both parties filed motions for clarification against the court’s decision, which were
partially granted. Although the contract between Confab and Veracel expressly provided that Confab would not
be liable for damages arising from lost profits, the court award would appear to include BRL78.8 million
(approximately $15.10 million) of damages arising therefrom. Confab has additional defense arguments in
respect of a claim for lost profits. On December 18, 2018, Confab filed an appeal against the first instance court
decision, and on April 30, 2019, Veracel filed its response to the appeal. In June 2022, the court resolved that it
lacked jurisdiction to decide on the appeal, which was re-allocated to another court. The parties are currently
waiting for the trial of the appeal to be scheduled. At this stage the Company cannot predict the outcome of the
claim or the amount or range of loss in case of an unfavorable outcome.
Petrobras-related proceedings and claims
The Company is aware that Brazilian, Italian and Swiss authorities investigated whether certain payments were made
prior to 2014 from accounts of entities presumably associated with affiliates of the Company to accounts allegedly
linked to individuals related to Petróleo Brasileiro S.A. (“Petrobras”) and whether any such payments were intended to
benefit the Company’s Brazilian subsidiary Confab.
Upon learning of the investigation, the audit committee of the Company's board of directors engaged external counsel
in connection with the Company’s review of these matters. In addition, the Company voluntarily notified the SEC and
the DOJ in October 2016. The Company conducted, with the assistance of external counsel, an internal investigation
and found no evidence corroborating any involvement by the Company or its directors, officers or employees in respect
of improper payments. An internal investigation commissioned by Petrobras also found no evidence that Confab
obtained any unfair commercial benefit or advantage from Petrobras in return for payments, including improperly
obtained contracts. On June 2, 2022, the Company resolved the investigation by the SEC, and the DOJ informed that it
had closed its parallel inquiry without taking action. Under the settlement with the SEC, the Company neither admits

Graphics
Annual Report 2022
94
nor denies the SEC’s findings and on June 24, 2022, paid $53.1 million in disgorgement and prejudgment interest and
$25 million for a civil penalty to conclude the matter.
In July 2019, the Company learned that the public prosecutors’ office of Milan, Italy, had completed a preliminary
investigation into the same alleged payments and had included in the investigation, among other persons, the
Company’s chairman and chief executive officer, two other board members, Gianfelice Rocca and Roberto Bonatti, and
the Company’s controlling shareholder, San Faustin. The Company is not a party to the proceedings. On March 22,
2022, upon completion of the evidentiary phase of the trial, the acting prosecutor requested the first-instance court in
Milan in charge of the case to impose sanctions on the Company’s chairman and chief executive officer, on the other
two board members, and on San Faustin. The Company’s outside counsel in Italy advised the Company that neither the
case file nor the prosecutor’s request contain or identify any evidence of involvement in, or knowledge of, the alleged
wrongdoing by any of the three directors. On May 26, 2022, the first-instance court dismissed the case brought by the
public prosecutor against the defendants for lack of jurisdiction and stated that the criminal proceeding should not
have been initiated. On October 7, 2022, the public prosecutor filed an appeal against the first-instance court’s
decision.
In June 2020, the Brazilian public prosecutors’ office requested the indictment of several individuals, including three
executives or former executives of Confab and a former agent of Confab, charging them with the alleged crimes of
corruption in relation to contracts executed between 2007 and 2010, and money laundering in relation to payments
between 2009 and 2013. These criminal proceedings are underway. Neither the Company nor Confab is a party to these
criminal proceedings.
In addition, Petrobras and the Brazilian public prosecutors filed civil claims for damages against, among others, Confab
and the Confab executives named in the criminal proceedings referred to above. Confab became aware of these civil
claims in September 2022. As of December 31, 2022, the aggregate amount of these claims was estimated at BRL284.2
million (or approximately $54.5 million). The plaintiffs also seek that Confab be prohibited from contracting with, or
receiving benefits or exemptions from, the Brazilian state for an unspecified term. Confab believes these claims do not
address either the defense arguments or the evidence available to the plaintiffs in Brazil and presented in other
jurisdictions and is vigorously contesting them. At this stage, the Company cannot predict the outcome of these civil
proceedings.
Putative class actions
Following the Company’s November 27, 2018, announcement that its Chairman and CEO Paolo Rocca had been
included in an Argentine court investigation known as the Notebooks Case (a decision subsequently reversed by a
higher court), two putative class action complaints were filed in the U.S. District Court for the Eastern District of New
York. On April 29, 2019, the court consolidated the complaints into a single case, captioned “In re Tenaris S.A. Securities
Litigation”, and appointed lead plaintiffs and lead counsel. On July 19, 2019, the lead plaintiffs filed an amended
complaint purportedly on behalf of purchasers of Tenaris securities during the putative class period of May 1, 2014,
through December 5, 2018. The individual defendants named in the complaint are Tenaris’s Chairman and CEO and
Tenaris’s former CFO. The complaint alleges that during the class period, the Company and the individual defendants
inflated the Tenaris share price by failing to disclose that the nationalization proceeds received by Ternium (in which
the Company held an 11.46% stake) when Sidor was expropriated by Venezuela were received or expedited as a result
of allegedly improper payments made to Argentine officials. The complaint does not specify the damages that plaintiff
is seeking. On October 9, 2020, the court granted in part and denied in part the defendants’ motions to dismiss. The
court partially granted and partially denied the motion to dismiss the claims against the Company and its Chairman and
CEO. In addition, the court granted the motions to dismiss as to all claims against San Faustin, Techint, and Tenaris’s
former CFO. On November 11, 2022, the parties filed a joint notice of settlement announcing a settlement in principle
of all claims in the action, subject to finalizing the settlement agreements and court approval. The parties’ agreement in
principle provides that, in exchange for dismissal of the action and customary releases from class members and with no
admission of liability by Tenaris or Mr. Rocca, Tenaris will pay to the class $9.5 million (inclusive of legal fees to lead
plaintiff’s counsel). On March 10, 2023, the lead plaintiffs filed a motion for preliminary approval of the class
settlement.
Administrative proceeding concerning Brazilian tax credits
Confab is a party to an administrative proceeding concerning the recognition and transfer of tax credits for an amount
allegedly exceeding the amount that Confab would have been entitled to recognize and / or transfer. The proceeding
resulted in the imposition of a fine against Confab representing approximately 75% of the allegedly undue credits,
which was appealed by Confab. On January 21, 2019, Confab was notified of an administrative decision denying

Graphics
Annual Report 2022
95
Confab’s appeal, thereby upholding the tax determination and the fine against Confab. On January 28, 2019, Confab
challenged such administrative decision and is currently awaiting a resolution. In case of an unfavorable resolution,
Confab may appeal before the courts. The estimated amount of this claim is BRL59.2 million (approximately $11.3
million). At this stage, the Company cannot predict the outcome of this claim.
U.S. patent infringement litigation
Tenaris Coiled Tubes, LLC (“TCT”), a U.S. subsidiary of the Company, was sued in 2017 by its competitor Global Tubing,
alleging defamatory conduct by TCT and seeking a declaration that certain Global Tubing products do not infringe
patents held by TCT. TCT counterclaimed that certain Global Tubing products did infringe patents held by TCT, and
Global Tubing has since sought to invalidate such patents. On December 13, 2019, Global Tubing filed an amended
complaint (including the Company as defendant), alleging, among other things, that TCT and the Company had misled
the patent office. On March 20, 2023, the judge granted summary judgment in favor of Global Tubing, concluding that
the patents at issue are unenforceable due to inequitable conduct during the patent prosecution process. TCT and the
Company are analyzing whether to appeal this judgment. Although it is not possible to predict the final outcome of this
matter, the Company believes that any potential losses arising from this case will not be material.
U.S. Antidumping Duty and Countervailing Duty Investigations
On October 27, 2021, the DOC announced the initiation of antidumping duty investigations of OCTG from Argentina,
Mexico, and Russia and countervailing duty investigations of OCTG from Russia and South Korea. The investigations
were initiated on the basis of a petition by U.S. Steel Tubular Products, Inc., a small number of other U.S. domestic
welded OCTG producers, and a steelworkers’ union. On November 22, 2021, the ITC made a preliminary determination
of injury, allowing the investigations to proceed. Subsequently, the DOC issued affirmative preliminary and final
antidumping determinations with respect to imports from Argentina, Mexico and Russia, and final affirmative
countervailing duty determinations with respect to imports from Russia and from some Korean exporters. On October
27, 2022, the ITC determined that the imports under investigation caused injury to the U.S. OCTG industry, bringing the
investigation phase to a conclusion. Tenaris and other parties have appealed the agency determinations from the
investigation to the Court of International Trade. As a result of the investigation, and unless overturned on appeal,
Tenaris is required to pay antidumping duty deposits (at a rate of 78.30% for imports from Argentina and 44.93% for
imports from Mexico) until such time the imports are reviewed by the DOC to determine whether final duties are
necessary for the specific period under review. Tenaris has been paying such deposits since May 11, 2022, reflecting the
amount of such deposits in its costs. The deposit rates may be reset periodically based on the results of the review
process. It is possible that, through the periodic review process, the deposits may be either returned to Tenaris in
whole or in part, or may be increased.
Dividend Policy
The Company does not have, and has no current plans to establish, a formal dividend policy governing the amount and
payment of dividends or other distributions. For a description of the shareholders’ and holders of ADS’ rights to receive
dividends and the conditions to declare and pay dividends, please refer to “Corporate Governance Statement

Significant Changes
Tenaris to increase its participation in Usiminas control group

On March 30, 2023, the Company’s subsidiary, Confab, together with Tenaris’s affiliates Ternium Investments and
Ternium Argentina, all of which compose the T/T Group within Usiminas control group, entered into a share purchase
agreement to acquire from the NSC Group, pro rata to their current participations in the T/T Group, 68.7 million
ordinary shares of Usiminas at a price of BRL10 (approximately $1.9) per ordinary share. Pursuant to the transaction,
Tenaris would pay approximately BRL 110 million (approximately $21 million) in cash for 11 million ordinary shares,
increasing its participation in the Usiminas control group to 9.8%. Upon the closing of this transaction, the T/T Group
will hold an aggregate participation of 61.3% in the control group, with the NSC Group and Previdência Usiminas
(Usiminas employees’ pension fund) holding 31.7% and 7.1%, respectively. The transaction is subject to approval by
Brazil’s antitrust authorities and will be financed with cash on hand.

At closing, the existing Usiminas shareholders agreement will be replaced by a new shareholders agreement setting
forth a new governance structure for Usiminas. The T/T Group will nominate a majority of the Usiminas board of
directors, the chief executive officer and four other members of the Usiminas board of officers. Of the positions
allocated to the T/T Group, Tenaris will retain the right to nominate one member of the Usiminas board of directors
and one members of the Usiminas board of officers. Ordinary decisions may be approved with a 55% majority of
Usiminas’ control group shares.

At any time after the second anniversary of the closing of the transaction, the T/T Group will have the right to buy the
NSC Group’s remaining interest in the Usiminas control group (153.1 million ordinary shares) at the higher of BRL10 per
share and the 40-trading day average price per share immediately prior to the date of exercising the option. In addition,
the NSC Group will have the right, at any time after the closing of the transaction, to withdraw its remaining shares
from the control group and sell them in the open market after giving the T/T Group the opportunity to buy them at the
40-trading day average price per share, as well as the right, at any time after the second anniversary of the closing, to
sell such shares to the T/T Group at BRL10 per share. Confab will have the right to participate in each such transaction
pro rata to its current participation in the T/T Group.

Additional Information
Exchange Controls
Many of the countries that are important markets for us or in which we have substantial assets have histories of
substantial government intervention in currency markets, volatile exchange rates and government-imposed currency
controls. These include mainly Argentina, Brazil, Indonesia, Mexico, Nigeria and Romania.
The Argentine peso was subject to a devaluation of approximately 73% against the U.S. dollar during 2022. The
Argentine authorities have implemented several measures to reduce volatility in the exchange rate between the ARS
and the USD and have implemented formal and informal restrictions on capital inflows into Argentina and capital
outflows from Argentina. Certain foreign exchange restrictions are currently in place. As a result, Tenaris’s Argentine
subsidiaries are currently required to repatriate to Argentina all proceeds for exports of goods (including U.S. dollars
received through advance payments and pre-financing facilities) and services and convert such proceeds into Argentine
pesos at the applicable exchange rate as of the repatriation date. Access to the Argentine foreign exchange market,
either to purchase foreign currency or to transfer foreign currency abroad (including to make import payments, to
repay foreign financial indebtedness, to pay services or dividends abroad, and for foreign currency-savings by
individuals and/or any other purchase or transfer of foreign exchange) is subject to certain conditions, including
extended payment terms from foreign suppliers. Prior approval from the Argentine central bank, which is rarely (if
ever) granted, is required to purchase foreign currency to pay dividends to foreign shareholders and to make other
payments to affiliates or third parties abroad. Throughout 2022, the Argentine central bank has continued to impose
foreign exchange restrictions aimed at limiting the purchase of foreign currency and the Argentine Securities
Commission imposed further restrictions to the sale of bonds by Argentine companies against foreign currency.
As of December 31, 2022, the total net equity of Argentine subsidiaries represented approximately 11% of Tenaris’s total
equity.
For additional information regarding factors affecting the Argentine economy, see “Key Information Risk Factors
Risks Relating to our Business and Industry Adverse economic or political conditions in the countries where we
operate or sell our products and services may decrease our sales or disrupt our manufacturing operations, thereby
adversely affecting our revenues, profitability and financial condition”. For additional information on current foreign
exchange restrictions in Argentina, see note 28 “Foreign exchange control measures in Argentina” of our audited
consolidated financial statements included in this annual report.
Taxation
The following discussion of the material Luxembourg and U.S. federal income tax consequences of an investment in our
shares and ADSs is based upon laws and relevant interpretations thereof in effect as of the date of this annual report,
all of which are subject to change. This discussion does not address all possible tax consequences relating to an
investment in our shares or ADSs, including the tax consequences under U.S. state and local tax laws.
Grand Duchy of Luxembourg
This section describes the material Luxembourg tax consequences of owning or disposing of shares or ADSs.
It is not intended to be, nor should it be construed to be, legal or tax advice. You should, therefore, consult your own tax
advisor regarding local or foreign tax consequences, including Luxembourg tax consequences of owning and disposing of

As used herein, a “Luxembourg individual” means an individual resident in Luxembourg who is subject to personal
income tax (impôt sur le revenu) on his or her worldwide income from Luxembourg or foreign sources, and a
“Luxembourg corporate holder” means a company (that is, a fully taxable collectivité within the meaning of Article 159
of the Luxembourg Income Tax Law) resident in Luxembourg subject to Luxembourg corporate income tax (impôt sur le
revenu des collectivités) and Luxembourg municipal business tax (impôt commercial communal) on its worldwide
income from Luxembourg or foreign sources. For the purposes of this summary, Luxembourg individuals and
Luxembourg corporate holders are collectively referred to as “Luxembourg Holders”. A “non-Luxembourg Holder” means
any investor in shares or ADSs of the Company other than a Luxembourg Holder.

Corporate Reorganization
The Company was established as a Luxembourg société anonyme holding under Luxembourg’s 1929 holding company
regime. Until termination of such regime on December 31, 2010, holding companies incorporated under the 1929
regime (including the Company) were exempt from Luxembourg corporate income tax, Luxembourg municipal business
tax, Luxembourg net wealth tax and Luxembourg withholding tax over dividends distributed to shareholders.
On January 1, 2011, the Company became an ordinary public limited liability company (société anonyme) and, effective
as from that date, the Company is subject to all applicable Luxembourg taxes, (including, among others, Luxembourg
corporate income tax on its worldwide income).
In light of the impending termination of Luxembourg’s 1929 holding company regime, in the fourth quarter of 2010, the
Company carried out a multi-step corporate reorganization, which included, among other transactions, the contribution
of most of the Company’s assets and liabilities to a wholly-owned, newly-incorporated Luxembourg subsidiary and the
restructuring of indirect holdings in certain subsidiaries. The first phase of the corporate reorganization was completed
in December 2010 and resulted in a non-taxable revaluation of the accounting value (under Luxembourg GAAP) of the
Company’s assets. The second phase of the reorganization was completed in 2011.
Following the completion of the first phase of the corporate reorganization, and upon its conversion into an ordinary
Luxembourg holding company, the Company recorded a special reserve in its tax balance sheet. Dividend distributions
for the foreseeable future will be charged to the special reserve and therefore should not be subject to Luxembourg
withholding tax.
Tax regime applicable to realized capital gains
Luxembourg Holders
Luxembourg resident individual holders
Capital gains realized by Luxembourg resident individuals who do not hold their shares or ADSs as part of a trade or
business (i.e. capital gains on private assets) and who hold (together, directly or indirectly, with his or her spouse or civil
partner and underage children) no more than 10% of the share capital of the Company, at any time during the five-year
period preceding the disposition will only be taxable (at a progressive rate) if they are realized on a sale of shares or
ADSs that takes place before their acquisition or within the first six months following their acquisition (i.e. speculative
gain). After the six-month period, capital gains are not taxed unless the resident individual holds (together, directly or
indirectly, with his or her spouse or civil partner and underage children) more than 10% of the share capital of the
Company at any time during the five-year period preceding the disposition.
If such shares or ADSs are held as part of a commercial or industrial business, capital gains would be taxable in the same
manner as income from such business.
Capital gains realized by Luxembourg resident individuals holding (alone or together with the resident’s spouse or civil
partner and underage children) directly or indirectly more than 10% of the capital of the Company at any time during
the five years prior to the sale, (or if the Luxembourg resident individuals have received the shares for no consideration
within the last five years and the former holder held at least 10% in the capital of the company at any moment during
said five years) will be taxable at half of the individual’s applicable global tax rate (as determined progressively), if a
holding period of six months following their acquisition elapsed (21% for 2022). Within the six-month period,
progressive income tax rates apply (ranging from 0 to 42%
7
in 2022).
Luxembourg resident corporate holders
Capital gains, including currency exchange gains, realized upon the disposal of shares or ADSs by a fully taxable resident
corporate holder will in principle be subject to Luxembourg corporate income tax and Luxembourg municipal business
tax. The combined applicable rate (including an unemployment fund contribution) for a corporate holder established in
Luxembourg-City is 24.94% for the fiscal year ending 2022. An exemption from such taxes may be available to the
Luxembourg resident corporate holder pursuant to Article 1 of the Grand Ducal Decree dated December 21, 2001, as

A 7% surcharge for the Employment Fund applies on the income tax due. The surcharge for the Employment Fund amounts to 9% for taxpayer in tax
class 1 or 1a with taxable income exceeding EUR 150,000 (EUR 300,000 for taxpayer in tax class 2).

amended, in combination with article 166 of the Luxembourg Income Tax Law subject to the fulfillment of the
conditions set forth therein.
Non-Luxembourg Holders
Non-Luxembourg individual holders
An individual who is a non-Luxembourg holder of shares or ADSs (and who does not have a permanent establishment, a
permanent representative or a fixed place of business in Luxembourg) will only be subject to Luxembourg taxation on
capital gains arising upon disposal of such shares or ADSs if such holder has (alone or together with his or her spouse,
civil partner and underage children) directly or indirectly held more than 10% of the capital of the Company at any time
during the past five years preceding the disposal, and either (i) such non-Luxembourg holder has been a resident of
Luxembourg for tax purposes for at least 15 years and has become a non-resident within the last five years preceding
the realization of the gain, subject to any applicable tax treaty, or (ii) the disposal of shares or ADSs occurs within six
months from their acquisition (or prior to their actual acquisition), subject, however, to any applicable tax treaty.
Non-Luxembourg corporate holders
A corporate non-Luxembourg holder (that is, a collectivité within the meaning of Article 159 of the Luxembourg Income
Tax Law), which has a permanent establishment, a permanent representative or a fixed place of business in
Luxembourg to which shares or ADSs are attributable, will bear Luxembourg corporate income tax and Luxembourg
municipal business tax on a gain realized on a disposal of such shares or ADSs as set forth above for a Luxembourg
corporate holder. However, capital gains, including currency exchange gains, realized on the sale of the shares or ADSs
may benefit from the full exemption provided for by Article 1 of the Grand Ducal Decree dated December 21, 2001, as
amended, in combination with Article 166 of the Luxembourg Income Tax Law subject in each case to fulfillment of the
conditions set out therein.
A corporate non-Luxembourg holder, which has no permanent establishment, permanent representative or fixed place
of business in Luxembourg to which the shares or ADSs are attributable, will bear non-resident capital gains tax on a
gain realized on a disposal of such shares or ADSs under the same conditions applicable to an individual non-
Luxembourg holder, as set out above.
Tax regime applicable to distributions
Withholding tax
Distributions to holders are in principle subject to a 15% Luxembourg withholding tax computed on the gross amount
distributed. The rate of the withholding tax may be reduced pursuant to double tax treaties existing between
Luxembourg and the country of residence of the relevant holder, subject to the fulfillment of the conditions set forth
therein. However, distributions imputed for tax purposes to the special reserve (please see above paragraph “corporate
reorganization”) should be exempt from Luxembourg withholding tax under the current tax law.
Nevertheless, a withholding tax exemption may apply if the distribution is made to (as far as relevant in the case at
hand):
a Luxembourg resident corporate holder (that is, a fully taxable collectivité within the meaning of article 159 of
the Luxembourg Income Tax Law);
an undertaking of collective character which is resident of a Member State of the European Union and is
referred to by article 2 of the EU Council Directive of November 30, 2011, concerning the common fiscal regime
applicable to parent and subsidiary companies of different member states (2011/96/UE) as amended, (subject to
the general anti-abuse rule provided for by Council Directive 2015/121/EU as implemented into Luxembourg
law);
a capital company or a cooperative company resident in Norway, Iceland or Liechtenstein and subject to a tax
comparable to corporate income tax as provided by the Luxembourg Income Tax Law;
a capital company resident in Switzerland which is subject to corporate income tax in Switzerland without
benefiting from an exemption;

Graphics
Annual Report 2022
101
an undertaking with a collective character subject to a tax comparable to corporate income tax as provided by
the Luxembourg Income Tax Law which is resident in a country that has concluded a double tax treaty with
Luxembourg; and
a Luxembourg permanent establishment of one of the above-mentioned categories, provided each time that at
the date of payment, the holder holds or commits to hold directly (or through a company regarded as tax
transparent from a Luxembourg tax perspective), during an uninterrupted period of at least twelve months,
shares or ADSs representing at least 10% of the share capital of the Company or acquired for an acquisition price
of at least EUR 1,200,000.
Luxembourg Holders
With the exception of Luxembourg corporate holders benefiting from the exemption referred to above, Luxembourg
individual holders, and Luxembourg corporate holders fully subject to Luxembourg corporate tax, must include the
distributions paid on the shares or ADSs in their taxable income, 50% of the amount of such dividends being exempt
from tax. The applicable withholding tax can, under certain conditions, entitle the relevant Luxembourg Holder to a tax
credit.
Non-Luxembourg Holders
Non-Luxembourg Holders of shares or ADSs and who do not have a permanent establishment, a permanent
representative or a fixed place of business in Luxembourg to which the shares or ADSs would be attributable are not
liable for any Luxembourg tax on dividends paid on the shares or ADSs, other than a potential withholding tax as
described above.
Net wealth tax
Luxembourg Holders
Luxembourg net wealth tax will not be levied on a Luxembourg holder with respect to the shares or ADSs held unless
(i) the Luxembourg holder is a legal entity subject to net wealth tax in Luxembourg; or (ii) the shares or ADSs are
attributable to an enterprise or part thereof which is carried on through a permanent establishment, a fixed place of
business or a permanent representative in Luxembourg.
Net wealth tax is levied annually at the rate of 0.5% for taxable net wealth not exceeding EUR 500,000,000 and at a rate
of 0.05% for the net wealth exceeding EUR 500,000,000, of enterprises resident in Luxembourg, as determined for net
wealth tax purposes. The shares or ADSs may be exempt from net wealth tax subject to the conditions set forth by
Paragraph 60 of the Luxembourg Law of October 16, 1934, on the valuation of assets (Bewertungsgesetz), as amended.
A minimum net wealth tax charge applies as of January 1, 2016, for all corporate entities having their statutory seat or
central administration in Luxembourg. Subject to certain conditions, the amount of minimum net wealth tax may vary.
Non-Luxembourg Holders
Luxembourg net wealth tax will not be levied on a non-Luxembourg holder with respect to the shares or ADSs held
unless the shares or ADSs are attributable to an enterprise or part thereof which is carried on through a permanent
establishment or a permanent representative in Luxembourg. The shares or ADSs may be exempt from net wealth tax
subject to the conditions set forth by Paragraph 60 of the Luxembourg Law of October 16, 1934 on the valuation of
assets (Bewertungsgesetz), as amended.
Stamp and registration taxes
No registration tax or stamp duty will be payable by a holder of shares or ADSs in Luxembourg solely upon the disposal
of shares or ADSs by sale or exchange.
Estate and gift taxes
No estate or inheritance tax is levied on the transfer of shares or ADSs upon the death of a holder of shares or ADSs in
cases where the deceased was not a resident of Luxembourg for inheritance tax purposes and no gift tax is levied upon

a gift of shares or ADSs if the gift is not passed before a Luxembourg notary or recorded in a deed registered in
Luxembourg.
Where a holder of shares or ADSs is a resident of Luxembourg for tax purposes at the time of the holder’s death, the
shares or ADSs are included in its taxable estate for inheritance tax or estate tax purposes.
U.S. federal income taxation
This section describes the material U.S. federal income tax consequences to a U.S. holder (as defined below) of owning
shares or ADSs. It applies to you only if you hold your shares or ADSs as capital assets for U.S. federal income tax
purposes. This discussion addresses only U.S. federal income taxation and does not discuss all of the tax consequences
that may be relevant to you in light of your individual circumstances, including foreign, state or local tax consequences,
estate and gift tax consequences, and tax consequences arising under the Medicare contribution tax on net investment
income or the alternative minimum tax. This section does not apply to you if you are a member of a special class of
holders subject to special rules, including:
a dealer in securities;
a bank;
a trader in securities that elects to use a mark-to-market method of accounting for securities holdings;
a tax-exempt organization;
a person who invests through a pass-through entity, including a partnership;
a life insurance company;
a person that actually or constructively owns 10% or more of the combined voting power of our voting stock or
of the total value of our stock (including ADSs);
a person that holds shares or ADSs as part of a straddle or a hedging or conversion transaction for U.S. federal
income tax purposes;
a person that purchases or sells shares or ADSs as part of a wash sale for U.S. federal income tax purposes; or
a person whose functional currency is not the U.S. dollar.
This section is based on the Internal Revenue Code of 1986, as amended, its legislative history, existing and proposed
regulations, published rulings and court decisions, all as currently in effect, as well as on the Convention between the
Government of the Grand Duchy of Luxembourg and the Government of the United States of America for the
Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on Income and Capital (the
“Treaty”). These laws are subject to change, possibly on a retroactive basis. In addition, this section is based in part
upon the assumption that each obligation in the ADS deposit agreement and any related agreement will be performed
in accordance with its terms.
If an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes holds the shares or
ADSs, the U.S. federal income tax treatment of a partner will generally depend upon the status of the partner and the
activities of the partnership. Each such partner of a partnership that holds the shares or ADSs is urged to consult his,
her or its own tax advisor.
You are a U.S. holder if you are a beneficial owner of shares or ADSs and you are, for U.S. federal income tax purposes:
an individual citizen or resident of the United States;
a domestic corporation (or an entity treated as a domestic corporation);
an estate whose income is subject to U.S. federal income tax regardless of its source; or

a trust if (i) a U.S. court can exercise primary supervision over the trust’s administration and one or more U.S.
persons are authorized to control all substantial decisions of the trust or (ii) the trust has a valid election in effect
under applicable U.S. Treasury regulations to be treated as a U.S. person.
In general, and taking into account the earlier assumptions, for U.S. federal income tax purposes, if you hold
ADSs, you will be treated as the owner of the shares represented by those ADSs. Exchanges of shares for
ADSs, and ADSs for shares, generally will not be subject to U.S. federal income tax.
The tax treatment of your shares or ADSs will depend in part on whether or not we are classified as a passive foreign
investment company (“PFIC”), for United States federal income tax purposes. Except as discussed below under “PFIC
Rules”, this discussion assumes that we are not classified as a PFIC for United States federal income tax purposes.
You should consult your own tax advisor regarding the U.S. federal, state and local and other tax consequences of
owning and disposing of shares or ADSs in your particular circumstances.
Taxation of distributions
Under the U.S. federal income tax laws, if you are a U.S. holder, the gross amount of any distribution we pay out of our
current or accumulated earnings and profits (as determined for U.S. federal income tax purposes), other than certain
pro-rata distributions of our shares, will be treated as a dividend that is subject to U.S. federal income taxation. If you
are a non-corporate U.S. holder, dividends paid to you that constitute qualified dividend income will be taxable to you
at the preferential rates applicable to long-term capital gains provided that you hold shares or ADSs for more than 60
days during the 121-day period beginning 60 days before the ex-dividend date and meet other holding period
requirements. Dividends we pay with respect to the shares or ADSs generally will be qualified dividend income,
provided that, in the year that you receive the dividend, we are eligible for the benefits of the Treaty. We believe that
we are currently eligible for the benefits of the Treaty and therefore expect that dividends on the shares or ADSs will be
qualified dividend income, but there can be no assurance that we will continue to be eligible for the benefits of the
Treaty.
You must generally include any Luxembourg tax withheld from the dividend payment in this gross amount even though
you do not in fact receive it. The dividend is taxable to you when you receive it, or, in the case of ADSs, when the
Depositary receives the dividend, actually or constructively. The dividend will not be eligible for the dividends-received
deduction generally allowed to U.S. corporations in respect of dividends received from other U.S. corporations.
Distributions in excess of current and accumulated earnings and profits, as determined for U.S. federal income tax
purposes, will be treated as a non-taxable return of capital to the extent of your basis in the shares or ADSs and
thereafter as capital gain. However, we do not expect to calculate earnings and profits in accordance with U.S. federal
income tax principles. Therefore, you should expect that a distribution will generally be treated as a dividend (as
discussed above).
Dividends will generally be income from sources outside the United States and, generally, will be “passive” income for
purposes of computing the foreign tax credit allowable to you.
Subject to certain limitations, the Luxembourg tax withheld in accordance with the Treaty and paid over to Luxembourg
may be creditable or deductible against your U.S. federal income tax liability. However, under recently finalized Treasury
regulations, it is possible that taxes may not be creditable unless you are eligible for and elect to apply the benefits of
the Treaty. Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject
to the preferential tax rates. To the extent a refund of the tax withheld is available to you under Luxembourg law or
under the Treaty, the amount of tax withheld that is refundable will not be eligible for credit against your U.S. federal
income tax liability.
In certain circumstances, if you have held ADSs for less than a specified minimum period during which you are not
protected from risk of loss, or are obligated to make payments related to the dividends, you will not be allowed a
foreign tax credit for foreign taxes imposed on dividends that we pay.
The rules governing the foreign tax credit are complex. You are urged to consult your tax advisors regarding the
availability of the foreign tax credit under your particular circumstances.
Taxation of capital gains
If you are a U.S. holder and you sell or otherwise dispose of your shares or ADSs, you will recognize capital gain or loss
for U.S. federal income tax purposes equal to the difference between the U.S. dollar value of the amount that you
realize and your tax basis, determined in U.S. dollars, in your shares or ADSs. Capital gain of a non-corporate U.S. holder

Graphics
Annual Report 2022
104
is generally taxed at preferential rates where the property is held for more than one year. The gain or loss will generally
be income or loss from sources within the United States for foreign tax credit limitation purposes. The deductibility of
capital losses is subject to limitations.
PFIC rules. Based on the Company’s current and expected income and assets, we believe that the shares or ADSs should
not currently be treated as stock of a PFIC for U.S. federal income tax purposes, and we do not expect to become a PFIC
in the foreseeable future. However, this conclusion is a factual determination that is made annually and thus may be
subject to change. It is therefore possible that we could become a PFIC in a future taxable year. If we were to be treated
as a PFIC, gain realized on the sale or other disposition of your shares or ADSs would in general not be treated as capital
gain. Furthermore, if you are a U.S. holder, unless you are permitted to elect and you do elect to be taxed annually on a
mark-to-market basis with respect to the shares or ADSs, upon sale or disposition of your shares or ADSs, you would
generally be treated as if you had realized such gain and certain “excess distributions” ratably over your holding period
for the shares or ADSs and would be taxed at the highest tax rate in effect for each such year to which the gain was
allocated, together with an interest charge in respect of the tax attributable to each such year. With certain exceptions,
your shares or ADSs will be treated as stock in a PFIC if we were a PFIC at any time during your holding period in your
shares or ADSs. Dividends that you receive from us will not be eligible for the special tax rates applicable to qualified
dividend income if we are a PFIC (or are treated as a PFIC with respect to you) either in the taxable year of the
distribution or the preceding taxable year, but instead will be taxable at rates applicable to ordinary income and subject
to the excess distribution regime described above.
Documents on Display
The Company is subject to the reporting requirements of the Exchange Act, as applied to foreign private issuers.
Accordingly, the Company is required to file annual and special reports and other information with the SEC; however,
foreign private issuers are not required to deliver proxy statements or to file quarterly reports. We prepare quarterly
and annual consolidated financial statements in accordance with IFRS. The Company’s annual consolidated financial
statements are audited by an independent accounting firm. The Company submits quarterly financial information with
the SEC on Form 6-K simultaneously with or promptly following the publication of such information in Luxembourg and
any other jurisdiction in which the Company’s securities are listed. In addition, the Company files annual reports on
Form 20-F within the time period required by the SEC, which is currently four months from the close of the Company’s
fiscal year on December 31. Reports and other information filed electronically with the SEC are available at the SEC’s
Internet website at http://www.sec.gov. In addition, such reports and other communications are made available to all
shareholders and holders of ADSs on the Company’s website at: https://ir.tenaris.com/investor-relations.
For the year ended December 31, 2022, Deutsche Bank Trust Company Americas acted as depositary under the ADSs
deposit agreement. As long as the deposit agreement remains in effect, the Company will furnish the Depositary with:
its annual reports; and
copies of all notices of shareholders’ meetings and other reports and communications that are made generally
available to the Company’s shareholders.
The Depositary will, as provided in the deposit agreement and if requested in writing by the Company, arrange for the
mailing of such reports, notices and communications to all record holders of ADSs, on a basis similar to that for holders
of shares, or on such other basis as the Company may advise the Depositary may be required by any applicable law or
regulation or any requirement of any stock exchange to which the Company may be subject. Any reports and
communications, including any proxy solicitation material, shall be furnished in English to the extent such materials are
required to be translated into English pursuant to any regulations of the SEC.
Any record holder of ADSs may read the reports, notices, and other communications including any proxy solicitation
material at the Depositary’s office located at One Columbus Circle, New York, New York 10019.

Quantitative and Qualitative Disclosure about Market Risk
The multinational nature of our operations and customer base expose us to a variety of risks, including the effects of
changes in foreign currency exchange rates, interest rates and commodity prices. In order to reduce the impact related
to these exposures, management evaluates exposures on a consolidated basis to take advantage of natural exposure
netting. For the residual exposures, we may enter into various derivative transactions in order to reduce potential
adverse effects on our financial performance. Such derivative transactions are executed in accordance with internal
policies and hedging practices. We do not enter into derivative financial instruments for trading or other speculative
purposes, other than non-material investments in structured products.
The following information should be read together with section III, “Financial risk management” to our audited
consolidated financial statements included elsewhere in this annual report.

As most borrowings are based on short-term fixed rates, or variable rates that approximate market rates, with interest rate resetting every 3 to 6
months, the fair value of the borrowings approximates its carrying amount and is not disclosed separately.
Our weighted average interest rates before tax (considering hedge accounting), amounted to 9.45% at December 31,
2022 and to 2.09% at December 31, 2021.
Our financial liabilities (other than trade payables and derivative financial instruments) consist mainly of bank loans. As
of December 31, 2022, U.S. dollar denominated financial debt plus debt denominated in other currencies swapped to
the U.S. dollar represented 78% of total financial debt.
For further information about our financial debt, please see note 20 “Borrowings” to our audited consolidated financial
statements included in this annual report.
Interest Rate Risk
Fluctuations in market interest rates create a degree of risk by affecting the amount of our interest payments. At
December 31, 2022, we had variable interest rate debt of $231 million and fixed rate debt of $498 million ($479 million
of the fixed rate debt is short-term).

Annual Report 2022

Foreign Exchange Rate Risk
We manufacture and sell our products in a number of countries throughout the world and consequently we are
exposed to foreign exchange rate risk. Since the Company’s functional currency is the U.S. dollar, the purpose of our
foreign currency hedging program is mainly to reduce the risk caused by changes in the exchange rates of other
currencies against the U.S. dollar.
Most of our revenues are determined or influenced by the U.S. dollar. In addition, a relevant part of our costs
corresponds to steelmaking raw materials and steel coils and plates, also determined or influenced by the U.S. dollar.
However, outside the United States, a portion of our expenses is incurred in foreign currencies (e.g. labor costs).
Therefore, when the U.S. dollar weakens in relation to the foreign currencies of the countries where we manufacture
our products, the U.S. dollar-reported expenses increase. Had the U.S. dollar average exchange rate been weaker by 5%
against the currencies of the countries where we have labor costs, operating income would have decreased
approximately by $60 million in 2022, compared to $46 million in 2021.
Our consolidated exposure to currency fluctuations is reviewed on a periodic basis. A number of hedging transactions
are performed in order to achieve an efficient coverage in the absence of operative or natural hedges. Almost all of
these transactions are forward exchange rate contracts.
Because certain subsidiaries have functional currencies other than the U.S. dollar, the results of hedging activities as
reported in the income statement under IFRS may not reflect entirely management’s assessment of its foreign
exchange risk hedging needs. Also, intercompany balances between our subsidiaries may generate exchange rate
results to the extent that their functional currencies differ.
The value of our financial assets and liabilities is subject to changes arising out of the variation of foreign currency
exchange rates. The following table provides a breakdown of our main financial assets and liabilities (including foreign
exchange derivative contracts) that impact our profit and loss as of December 31, 2022.

The main relevant exposures as of December 31, 2022 were to Argentine Peso-denominated financial, trade, social and
fiscal payables at our Argentine subsidiaries, for which the functional currency is the U.S. dollar, Euro-denominated
intercompany liabilities at certain subsidiaries whose functional currency is the U.S. dollar, U.S. dollar-denominated
intercompany liabilities at certain subsidiaries whose functional currency is the Brazilian Real and Saudi Arabian Riyal-
denominated financial and trade payables. The Saudi Arabian Riyal is tied to the dollar.
Foreign Currency Derivative Contracts
The net fair value of our foreign currency derivative contracts amounted to an asset of $27 million at December 31,
2022 and an asset of $20 thousand at December 31, 2021. For further detail on our foreign currency derivative
contracts, please see note 25 “Derivative financial instruments Foreign exchange and commodities derivative
contracts and hedge accounting” to our audited consolidated financial statements included in this annual report.
Concentration of Credit Risk
There is no significant concentration of credit from customers. No single customer comprised more than 10% of our net
sales in 2022, 2021 and 2020.
Our credit policies related to sales of products and services are designed to identify customers with acceptable credit
history, and to allow us to use credit insurance, letters of credit and other instruments designed to minimize credit risk
whenever deemed necessary. We maintain allowances for potential credit losses.

Commodity Price Risk
In the ordinary course of its operations, Tenaris purchases commodities and raw materials that are subject to price
volatility caused by supply conditions, political and economic variables and other factors. As a consequence, Tenaris is
exposed to risk resulting from fluctuations in the prices of these commodities and raw materials. Tenaris fixes the prices
of such raw materials and commodities for short-term periods, typically not in excess of one year, and in general
hedging for these risks is performed on a limited basis.
Commodities Derivative Contracts
The net fair value of our commodities derivative contracts amounted to a liability of $3 million at December 31, 2022
and a liability of $33 thousand at December 31, 2021. For further detail on our commodities derivative contracts, please
see note 25 “Derivative financial instruments Foreign exchange and commodities derivative contracts and hedge
accounting” to our audited consolidated financial statements included in this annual report.
Accounting for Derivative Financial Instruments and Hedging Activities
Derivative financial instruments are classified as financial assets (or liabilities) at fair value through profit or loss. Their
fair value is calculated using standard pricing techniques and, as a general rule, we recognize the full amount related to
the change in its fair value under financial results in the current period.
We designate for hedge accounting certain derivatives and non-derivative financial liabilities to hedge risks associated
with recognized assets, liabilities or highly probable forecast transactions. These instruments are classified as cash flow
hedges. The effective portion of the fair value of such derivatives is accumulated in a reserve account in equity.
Amounts accumulated in equity are then recognized in the income statement in the same period when the offsetting
losses and gains on the hedged item are recorded. The gain or loss relating to the ineffective portion is recognized
immediately in the income statement. The fair value of our derivative financial instruments (assets or liabilities)
continues to be reflected on the consolidated statement of financial position.
At December 31, 2022, the effective portion of designated cash flow hedges, included in other reserves in shareholders’
equity amounted to a credit of $13.1 million.

Description of Securities Other Than Equity Securities
American Depositary Shares
According to the Company’s deposit agreement, holders of ADSs may have to pay to the Depositary, either directly or
indirectly, fees or charges up to the amounts set forth below:
A fee of $5.00 (or less) per 100 ADSs (or portion of 100 ADSs) for: issuance of ADSs, including issuances resulting
from a distribution of shares or rights or other property; and cancellation of ADSs for the purpose of withdrawal,
including if the deposit agreement terminates.
A fee of $0.02 (or less) per ADSs for any cash distribution to ADS registered holders, excluding cash dividend.
Any charges for taxes and other governmental charges that the Depositary or the custodian may be required to
pay on any ADS or share underlying an ADS (e.g., share transfer taxes, stamp duty or withholding taxes); and any
charges incurred by the Depositary or its agents for servicing the depositary securities.
Registration or transfer fees for transfer and registration of shares on our share register to or from the name of
the Depositary or its agent when you deposit or withdraw shares.
Expenses of the Depositary for cable, telex and facsimile transmissions (when expressly provided in the deposit
agreement) and conversion of foreign currency.
A fee equivalent to the fee that would be payable if securities distributed to ADS holders had been shares and
the shares had been deposited for issuance of ADSs for distribution of securities distributed to holders of
deposited securities which are distributed by the Depositary to ADS registered holders.
As necessary, charges for any costs incurred by the Depositary or its agents for servicing the deposited securities.
The Depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or
surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The Depositary collects fees
for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of
distributable property to pay the fees. The Depositary may collect its annual fee for depositary services by deduction
from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants
acting for them. The Depositary may generally refuse to provide fee-attracting services until its fees for those services
are paid.
Under the deposit agreement with the Depositary, the Depositary is not liable to holders of ADSs, except that the
Depositary agrees to perform its obligations specifically set forth therein without gross negligence and willful
misconduct.
Fees Payable by the Depositary to the Company
Under its agreement with the Depositary, the Company is entitled to receive certain fees from the Depositary, based on
the Depositary’s revenues resulting from issuance and cancellation fees charged to ADR holders, net of custody and
safe keeping costs. In addition, the Depositary has waived the cost of providing administrative and reporting services,
and access charges in connection with the Company’s ADR Program.
Fees paid in 2022
In 2022, the Company received from the Depositary fees for an amount of $1,162,434, corresponding to the period
March 1, 2021 through March 12, 2022.
Fees payable during 2023
During 2023, the Company collected fees from the Depositary for an amount of $932,082, corresponding to the
period March 13, 2022 through March 12, 2023.

Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Under the supervision and with the participation of our management, including the Company’s chief executive officer
and chief financial officer, we have evaluated the effectiveness of the design and operation of our disclosure controls
and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31,
2022.
Based on that evaluation, the Company’s chief executive officer and chief financial officer have concluded that, as of
December 31, 2022, our disclosure controls and procedures are effective to ensure that information required to be
disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified in the SEC’s rules and forms and to ensure that such information is
accumulated and communicated to management, including the Company’s chief executive officer and chief financial
officer, to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to
provide reasonable assurance of achieving their objectives. The Company’s chief executive officer and chief financial
officer have concluded that our disclosure controls and procedures are effective at a reasonable assurance level.
Management’s Report on Internal Control over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting (as such
term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control over financial reporting
was designed by management to provide reasonable assurance regarding the reliability of financial reporting and the
preparation and fair presentation of its financial statements for external purposes in accordance with IFRS.
In addition, under the Company’s articles of association, as supplemented by the audit committee’s charter, the audit
committee assists the board of directors in fulfilling its oversight responsibilities relating to the effectiveness of the
Company’s systems of internal control, risk management and internal audit over financial reporting. In particular, the
audit committee is required to review the scope and results of the activities of the Company’s external auditors and the
internal audit function relating to the Company’s internal control over financial reporting, and obtain reports on
significant findings and recommendations; and is also required to assess, at least annually at the time the annual
accounts are approved, the effectiveness of the Company’s systems of internal control and risk management over
financial reporting.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements or
omissions. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies
or procedures may deteriorate.
On a yearly basis, management conducts its assessment of the effectiveness of Tenaris’s internal control over financial
reporting based on the framework in Internal Control- Integrated Framework (2013) issued by the Committee of
Sponsoring Organizations of the Treadway Commission.
On February 14, 2023, management reported to the Audit Committee of the Company’s board of directors that
management had conducted its assessment of the effectiveness of the Company’s internal controls over financial
reporting for the year ended December 31, 2022, and that, based on management’s evaluation and considering the
inherent limitations to the effectiveness of any internal control system, management had concluded that the
Company’s internal controls over financial reporting were effective as of December 31, 2022.
The effectiveness of Tenaris’s internal control over financial reporting as of December 31, 2022, has been audited by
PwC Luxembourg, as stated in their report included herein. See “Report of Independent Registered Public Accounting
Firm”.

the attributes defined by the SEC for an “audit committee financial expert” and has competence in accounting or
auditing matters, as required by applicable Luxembourg law. In addition, the audit committee, as a whole, has sufficient
relevant knowledge of the business and financial experience to properly discharge its functions. The audit committee
has the authority to engage, at the Company’s expense, independent counsel and other internal or external advisors to
review, investigate or otherwise advise on, any matter, as the audit committee may determine to be necessary to carry
out its purposes and responsibilities.

Audit Committee’s Pre-approval Policies and Procedures
The Company’s Audit Committee is responsible for, among other things, the oversight of the Company’s external
auditors. Under its charter, the audit committee is responsible to review the appropriateness of, and approve, in
advance, the provision of any permissible non-audit services by the external auditors; and to review and approve any
fees, whether for audit, audit-related, or non-audit services payable to the external auditors.
The audit committee makes its recommendations to the shareholders’ meeting concerning the continuing appointment
or termination of the Company’s external auditors. On a yearly basis, the audit committee reviews, together with
management and the external auditor, the audit plan, audit related services and other permissible non-audit services
and approves, ad-referendum of the general shareholders’ meeting, the related fees. With respect to non-audit
services, the audit committee annually approves an estimated amount for undetermined non-audit services,
conditioned upon final review and approval of such services by the audit committee. The audit committee annually
receives from the external auditor the written disclosures required by PCAOB Rule 3524 “Audit Committee Pre-
Approval of Certain Tax Services”, together with a description of the scope of tax services for such year, and the
external auditors’ confirmation that such non-audit services are consistent with the Sarbanes-Oxley Act, SEC Regulation
S-X Rule 2-01, and applicable PCAOB rules. The Audit Committee did not approve any fees pursuant to the de minimis

exception to the pre-approval requirement provided by paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X during 2022
or 2021.
The general shareholders’ meeting normally approves such audit fees and authorizes the audit committee to approve
any increase or reallocation of such audit fees as may be necessary, appropriate or desirable under the circumstances.
No services outside the scope of the audit committee’s approval may be undertaken by the external auditor.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers
In 2022, there were no purchases of any class of registered equity securities of the Company by the Company or, to our
knowledge, by any “affiliated purchaser” (as such term is defined in Rule 10b-18(a)(3) under the Exchange Act).
On June 2, 2020, at the Company’s general meeting of shareholders, the Company’s shareholders authorized the
Company and the Company’s subsidiaries to acquire, from time to time, shares, including shares represented by ADSs,
on the following terms and conditions:
Purchases, acquisitions or receipts of securities may be made in one or more transactions as the board of
directors of the Company or the board of directors or other governing bodies of the relevant entity, as
applicable, considers advisable.
The maximum number of securities acquired pursuant to this authorization may not exceed 10% of the
Company’s issued and outstanding shares or, in the case of acquisitions made through a stock exchange in which
the securities are traded, such lower amount as may not be exceeded pursuant to any applicable laws or
regulations of such market. The number of securities acquired as a block may amount to the maximum
permitted amount of purchases.
The purchase price per share to be paid in cash may not exceed 125% (excluding transaction costs and
expenses), nor may it be lower than 75% (excluding transaction costs and expenses), in each case of the average
of the closing prices of the Company’s securities in the stock exchange through which the Company’s securities
are acquired, during the five trading days in which transactions in the securities were recorded in such stock
exchange preceding (but excluding) the day on which the Company’s securities are acquired. For over-the-
counter or off-market transactions, the purchase price per ADS to be paid in cash may not exceed 125%
(excluding transaction costs and expenses), nor may it be lower than 75% (excluding transaction costs and
expenses), in each case of the average of the closing prices of the ADSs in the NYSE during the five trading days
in which transactions in ADSs were recorded in the NYSE preceding (but excluding) the day on which the ADSs
are acquired; and, in the case of acquisition of securities, other than in the form of ADSs, such maximum and
minimum per security purchase prices shall be equal to the prices that would have applied in case of an ADS
purchase pursuant to the formula above divided by the number of underlying shares represented by an ADS at
the time of the relevant purchase. Compliance with maximum and minimum purchase price requirements in any
and all acquisitions made pursuant to this authorization (including, without limitation, acquisitions carried out
through the use of derivative financial instruments or option strategies) shall be determined on and as of the
date on which the relevant transaction is entered into, irrespective of the date on which the transaction is to be
settled.
The above maximum and minimum purchase prices shall, in the event of a change in the par value of the
securities, a capital increase by means of a capitalization of reserves, a distribution of securities under
compensation or similar programs, a stock split or reverse stock split, a distribution of reserves or any other
assets, the redemption of capital, or any other transaction impacting on the Company’s equity, be adapted
automatically, so that the impact of any such transaction on the value of the securities shall be reflected.
The acquisitions of securities may not have the effect of reducing the Company’s net assets below the sum of
the Company’s share capital plus its undistributable reserves.
Only fully paid-up securities may be acquired pursuant to this authorization.
The acquisitions of securities may be carried out for any purpose, as may be permitted under applicable laws
and regulations, including without limitation to reduce the share capital of the Company, to offer such shares to
third parties in the context of corporate mergers or acquisitions of other entities or participating interests
therein, for distribution to the Company’s or the Company’s subsidiaries’ directors, officers or employees or to
meet obligations arising from convertible debt instruments.
The acquisitions of securities may be carried out by any and all means, as may be permitted under applicable
laws and regulations, including through any stock exchange in which the Company’s securities are traded,
through public offers to all shareholders of the Company to buy securities, through the use of derivative financial
instruments or option strategies, or in over-the-counter or off-market transactions or in any other manner.

Annual Report 2022
117
The acquisitions of securities may be carried out at any time, during the duration of the authorization, including
during a tender offer period, as may be permitted under applicable laws and regulations.
The authorization granted to acquire securities shall be valid for such maximum period as may be provided for
under applicable Luxembourg law as in effect from time to time (such maximum period being, as of to date, 5
years).
The acquisitions of securities shall be made at such times and on such other terms and conditions as may be
determined by the board of directors of the Company or the board of directors or other governing bodies of the
relevant subsidiary, provided that, any such purchase shall comply with Article 430-15 et. seq. of the
Luxembourg Company Law (or any successor law) and, in the case of acquisitions of securities made through a
stock exchange in which the Company’s securities are traded, with any applicable laws and regulations of such
market.
In the future, we may, on the terms and subject to the conditions above referred, initiate a share capital repurchase or
similar program or engage in other transactions pursuant to which we would repurchase, directly or indirectly, the
Company’s securities. In addition, we or our subsidiaries may enter into transactions involving sales or purchases of
derivatives or other instruments, either settled in cash or through physical delivery of securities, with returns linked to
the Company’s securities. The timing and amount of repurchase transactions under any such program, or sales or
purchases of derivatives or other instruments, would depend on market conditions as well as other corporate and
regulatory considerations.

Change in Registrant’s Certifying Accountant
Following the completion of a tender process for the selection of a replacement audit firm for the year 2024, in
response to applicable EU and Luxembourg mandatory auditor rotation rules, on November 3, 2022, the Company’s
board of directors, based on the audit committee’s recommendation, recommended that the next annual general
shareholders’ meeting, scheduled to be held on May 3, 2023, appoint EY as the Company’s external auditors for the
fiscal year ending December 31, 2024.

Corporate Governance Statement
The Company’s corporate governance practices are governed by Luxembourg Law (including, among others, the
Luxembourg Company Law, the Luxembourg Law of January 11, 2008 on transparency requirements for issuers, as
amended (which transposes EU Directive 2004/109 of the European Parliament and of the Council of December 15,
2004), the Shareholders’ Rights Law and the Luxembourg law of July 23, 2016, concerning the audit profession (the
Audit Reform Law”) and by the Company’s articles of association. The following is a summary of certain rights of
holders of the Company’s shares and includes the information required under the Luxembourg Law on takeovers of
May 19, 2006. Shareholders’ rights are set out in the Company’s articles of association and are provided by applicable
Luxembourg law, and may differ from those typically provided to shareholders of U.S. companies under the corporation
laws of some states of the United States. This summary is not exhaustive and does not contain all information that may
be important to investors. For more complete information, you should read the Company’s articles of association,
which are attached as an exhibit to this annual report.
Corporate Governance
Memorandum and Articles of Association
The Company is a public limited liability company (société anonyme) organized under the laws of Luxembourg,
registered under the number B85 203 in the Luxembourg Registre de Commerce et des Sociétés. Its object and purpose,
as set forth in Article 2 of its articles of association, is the taking of interests, in any form, in corporations or other
business entities, and the administration, management, control and development thereof.
The Company’s authorized share capital is fixed by the Company’s articles of association as amended from time to time
with the approval of shareholders at an extraordinary general shareholders’ meeting. The Company has an authorized
share capital of a single class of 2,500,000,000 shares having a nominal value of USD1.00 per share. There were
1,180,536,830 shares issued as of the date of this annual report. All issued shares are fully paid.
The Company’s articles of association authorize the board of directors, or any delegate(s) duly appointed by the board
of directors, to issue shares within the limits of the authorized share capital against contributions in cash, contributions
in kind or by way of available reserves, at such time and on such terms and conditions, including the issue price, as the
board of directors, or its delegate(s), may in its or their discretion resolve.
The Company’s extraordinary shareholders’ meeting held on June 2, 2020 approved the renewal for an additional five-
year period of the authorization granted to the board of directors to waive, suppress or limit any preemptive
subscription rights of shareholders provided for by law to the extent it deems such waiver, suppression or limitation
advisable for any issue or issues of shares within the authorized share capital; and have waived any preemptive
subscription rights provided for by law and related procedures. The validity period of such authorization will expire on
June 12, 2025. However, under the Company’s articles of association, the Company’s existing shareholders shall have a
preferential right to subscribe for any new shares issued pursuant to the authorization granted to its board of directors,
except in the following cases (in which cases no preemptive subscription rights shall apply):
any issuance of shares (including, without limitation, the direct issuance of shares or upon the exercise of
options, rights convertible into shares, or similar instruments convertible or exchangeable into shares) against a
contribution other than in cash; and
any issuance of shares (including by way of free shares or at discount), up to an amount equal to 1.5% of the
issued share capital of the Company, to directors, officers, agents or employees of the Company, its direct or
indirect subsidiaries, or its affiliates, including, without limitation, the direct issuance of shares or upon the
exercise of options, rights convertible into shares, or similar instruments convertible or exchangeable into
shares, issued for the purpose of compensation or incentive for any such persons or in relation thereto (which
the board of directors shall be authorized to issue upon such terms and conditions as it deems fit).
Amendment of the Company’s articles of association requires the approval of shareholders at an extraordinary
shareholders’ meeting with a two-thirds majority vote of the shares represented at the meeting.

The Company is controlled by San Faustin, which owns 60.45% of the Company’s outstanding shares, through its wholly
owned subsidiary Techint Holdings S.à r.l. The Dutch private foundation (Stichting) RP STAK holds voting rights in San
Faustin sufficient to control San Faustin. No person or group of persons controls RP STAK.
Our directors and senior management as a group own 0.07% of the Company’s outstanding shares, while the remaining
39.48% are publicly traded. The Company’s shares trade on the Italian Stock Exchange and the Mexican Stock Exchange;
in addition, the Company’s ADSs trade on the NYSE. See “Major Shareholders and Related Party Transactions”.
Dividends
Subject to applicable law, all shares (including shares underlying ADSs) are entitled to participate equally in dividends
when, as and if declared by the shareholders at the annual general shareholders’ meeting, out of funds legally available
for such purposes.
Dividends may be lawfully declared and paid if the Company’s net profits and distributable reserves are sufficient under
Luxembourg law. The amount and payment of dividends must be approved by a majority vote at a general
shareholders’ meeting, generally, but not necessarily, based on the recommendation of the Company’s board of
directors. Under Article 21 of the Company’s articles of association, the board of directors has the power to distribute
interim dividends out of profits, share premium or any other available reserves, in accordance with applicable law, in
particular in accordance with the conditions set forth in Article 461-3 of the Luxembourg Company Law. Such dividend
payments must be finally approved by the general shareholders’ meeting. On February 15, 2023 the board of directors
announced the proposals to be submitted to the consideration of the annual general shareholders’ meeting, including
its proposal on dividends.
As provided by Article 21 of the Company’s articles of association, dividends or other distributions declared by the
general meeting as well as interim dividends or other distributions declared by the board of directors will be distributed
at the times and places determined by the board of directors. The Company will make any and all dividend payments
and any other distributions in respect of shares registered in the name of any securities settlement system or operator
of such a system or in the name of any financial institution or other professional depositary of securities or any other
depositary, whether in cash, shares or other assets, only to such registered holder, or otherwise in accordance with
such registered holder’s instructions, and, as provided by Article 21 of the Company’s articles of association, that
payment shall release the Company from any and all obligations for such payment.
The Company conducts and will continue to conduct its operations through subsidiaries and, accordingly, its main
source of cash to pay dividends, among other possible sources, will be the dividends received from its subsidiaries. For
further information see “Key Information Risk Factors Risks Relating to the Structure of the Company The
Company’s dividend payments depend on the results of operations and financial condition of its subsidiaries and could
be restricted by legal, contractual or other limitations or tax changes”.
Under Luxembourg law, claims for dividends will lapse in favor of the Company five years after the date such dividends
are declared. However, the Company may elect to pay a declared dividend after such period. Declared and unpaid
dividends held by the Company for the account of its shareholders do not bear interest.
Pursuant to Luxembourg law, at least 5% of our net profits per year must be allocated to the creation of a legal reserve
until such reserve has reached an amount equal to 10% of our issued share capital. If the legal reserve later falls below
the 10% threshold, at least 5% (or such lower amount required to reach the 10% threshold) of net profits again must be
allocated toward the reserve. As of December 31, 2022, the Company’s legal reserve represented 10% of its share
capital. The legal reserve is not available for distribution.
Shareholders’ Meetings; Voting Rights; Election of Directors
Each share entitles the holder thereof to one vote at the Company’s general shareholders’ meetings. Shareholder
action by written consent is not permitted, but proxy voting is permitted. Notices of general shareholders’ meetings are
governed by the provisions of Luxembourg law and the Company’s articles of association. Pursuant to applicable
Luxembourg law, the Company must give notice of the calling of any general shareholders’ meeting at least 30 days
prior to the date for which the meeting is being called, by publishing the relevant convening notice in the Recueil
Electronique des Sociétés et Associations (Luxembourg’s electronic official gazette) and in a leading newspaper having
general circulation in Luxembourg and by issuing a press release informing of the calling of such meeting. In case the
Company’s shares are listed on a foreign regulated market, notices of general shareholders’ meetings shall also comply

Graphics
Annual Report 2022
121
with the requirements (including as to content and publicity) and follow the customary practices of such regulated
market.
Pursuant to the Company’s articles of association, for as long as the shares or other securities of the Company are listed
on a regulated market within the European Union (as they currently are), and unless otherwise provided by applicable
law, only shareholders holding shares as of midnight, central European time, on the day that is fourteen days prior to
the day of any given general shareholders’ meeting can attend and vote at such meeting. The board of directors may
determine other conditions that must be satisfied by shareholders in order to participate in a general shareholders’
meeting in person or by proxy, including with respect to deadlines for submitting supporting documentation to or for
the Company.
No attendance quorum is required at ordinary general shareholders’ meetings, and resolutions may be adopted by a
simple majority of the votes validly cast, irrespective of the number of shares present or represented. Unless otherwise
provided by applicable law, an extraordinary general shareholders’ meeting may not validly deliberate on proposed
amendments to the Company’s articles of association unless a quorum of at least half of the share capital is
represented at the meeting. If a quorum is not reached at the first extraordinary shareholders’ meeting, a second
extraordinary shareholders’ meeting may be convened in accordance with the Company’s articles of association and
applicable law and such second extraordinary general shareholders’ meeting shall validly deliberate regardless of the
number of shares represented. In both cases, the Luxembourg Company Law and the Company’s articles of association
require that any resolution of an extraordinary general shareholders’ meeting as to amendments to the Company’s
articles of association be adopted by a two-thirds majority of the votes validly cast at the meeting. If a proposed
resolution consists of changing the Company’s nationality or of increasing the shareholders’ commitments, the
unanimous consent of all shareholders is required.
Cumulative voting is not permitted. The Company’s articles of association do not provide for staggered terms and
directors are elected for a maximum of one year but may be reappointed or removed at any time, with or without
cause, by the general shareholders’ meeting, by resolution passed by a simple majority vote of the shares validly cast at
the meeting. In the case of a vacancy occurring in the board of directors, the remaining directors shall have the right to
temporarily fill such vacancy with a temporary director appointed by resolution adopted with the affirmative vote of a
majority of the remaining directors; provided that the next general shareholder’s meeting shall be called upon to ratify
such appointment. The term of any such temporary director elected to fill a vacancy shall expire at the end of the term
of office of the replaced director.
The next Company’s annual general shareholders’ meeting, that will consider, among other matters our Consolidated
Financial Statements and Annual Accounts included in this annual report, will take place in the Company’s registered
office in Luxembourg, on Wednesday, May 3, 2023, at 4:00 p.m. Central European Time.
The articles of association provide that annual general shareholders’ meetings shall meet in Luxembourg within six
months from the end of the previous financial year at the date, place and hour indicated in the convening notice. The
rights of the shareholders attending the meetings are governed by Shareholders’ Rights Law.
Holders of shares deposited in fungible securities accounts have the same rights and obligations as holders of shares
recorded in the Company’s share register. However, in order to be able to participate in and vote at shareholders’
meetings of the Company, the former must submit, prior to the relevant meeting, reasonably satisfactory evidence to
the Company as to the number of shares held on the applicable record date for such meeting. For as long as the shares
or the other securities of the Company are listed on a regulated market within the European Union, participation in a
shareholders’ general meeting shall inter alia be subject to the relevant shareholder holding shares of the Company on
the fourteenth day midnight Central European Time prior to the meeting (unless otherwise provided for by applicable
law).
Holders of ADSs only have those rights that are expressly granted to them in the deposit agreement. See “Key
Information Risk Factors Risks Relating to shares and ADSs Holders of ADSs may not be able to exercise, or may
encounter difficulties in the exercise of, certain rights afforded to shareholders”. ADS holders may not attend or directly
exercise voting rights in shareholder’ meetings, but holders of record of our ADSs as of the relevant ADS holders’ record
date set for any given general shareholders’ meeting are entitled to instruct the Depositary as to the exercise of the
voting rights in respect of the shares underlying such holder’s ADSs at such meeting. Holders of ADSs maintaining non-
certificated positions must follow voting instructions given by their broker or custodian bank.

Brochure and Proxy Statement for the meeting, describing the procedures for voting at the meeting applicable to

holders of ADSs will be made available on the Company’s website at https://ir.tenaris.com/investor-relations in
accordance with applicable rules and regulations, and will be timely filed by the Company in a report of foreign issuer
on Form 6-K.
Management
Management of the Company is vested in a board of directors. For more information on the Company’s board of
directors, audit committee, senior management, and auditors, see “Directors, Senior Management and Employees”.
Access to Corporate Records
Luxembourg law and the Company’s articles of association do not generally provide for shareholder access to corporate
records. Shareholders may inspect the annual accounts and auditors’ reports at our registered office during the fifteen-
day period prior to a general shareholders’ meeting.
Appraisal Rights
In the event the Company’s shareholders approve:
the delisting of the shares from all stock exchanges where the shares are listed at that time;
a merger in which the Company is not the surviving entity (unless the shares or other equity securities of such
entity are listed on the New York or London stock exchanges);
a sale, lease, exchange or other disposition of all or substantially all of the Company’s assets;
an amendment of our articles of association that has the effect of materially changing the Company’s corporate
purpose;
the relocation of the Company’s domicile outside of the Grand Duchy of Luxembourg; or
amendments to the Company’s articles of association that restrict the rights of the Company’s shareholders.
Dissenting or absent shareholders have the right to have their shares repurchased by the Company at (i) the average
market value of the shares over the 90 calendar days preceding the applicable shareholders’ meeting or (ii) in the event
that the shares are not traded on a regulated market, the amount that results from applying the proportion of the
Company’s equity that the shares being sold represent over the Company’s net worth as of the date of the applicable
shareholders’ meeting.
Dissenting or absent shareholders must present their claim within one month following the date of the shareholders’
meeting and supply the Company with evidence of their shareholding at the time of such meeting. The Company must
(to the extent permitted by applicable laws and regulations and in compliance therewith) repurchase its shares within
six months following the date of the shareholders’ meeting.
If delisting from one or more, but not all, of the stock exchanges where the shares are listed is approved in the
shareholders’ meeting, only dissenting or absent shareholders with shares held through participants in the local
clearing system for that market or markets can exercise this appraisal right if:
they held the shares as of the date of the announcement by the Company of its intention to delist or as of the
date of publication of the first convening notice for the general shareholders’ meeting that approved the
delisting; and
they present their claim within one month following the date of the general shareholders’ meeting and supply
evidence of their shareholding as of the date of the Company’s announcement or the publication of the first
convening notice to the meeting.
In the event a shareholder exercises its appraisal rights, applicable Luxembourg law provisions shall apply.
Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights afforded to
shareholders, including appraisal rights. See “Key Information Risk Factors Risks Relating to shares and ADSs

Graphics
Annual Report 2022
123
Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights afforded to
shareholders”.
Distribution of Assets on Winding-Up
In the event of the Company’s liquidation, dissolution or winding-up, the net assets remaining after allowing for the
payment of all debts, charges and expenses will be paid out to the holders of the shares in proportion to their
respective holdings.
Transferability and Form
The Company’s articles of association do not contain any redemption or sinking fund provisions, nor do they impose
any restrictions on the transfer of shares. The shares are issuable in registered form only.
The ownership of registered shares is evidenced by the inscription of the name of the shareholder, the number of
shares held by such shareholders and the amount paid on each share in the Company’s share register. In addition, the
Company’s shares may be held through fungible securities accounts with financial institutions or other professional
depositaries.
Shares held through fungible securities accounts may be transferred in accordance with customary procedures for the
transfer of securities in book-entry form. Shares that are not held through fungible securities accounts may be
transferred by a written statement of transfer signed by both the transferor and the transferee or their respective duly
appointed attorney-in-fact and recorded in the Company’s share register. The transfer of shares may also be made in
accordance with the provisions of Article 1690 of the Luxembourg Civil Code. As evidence of the transfer of registered
shares, the Company may also accept any correspondence or other documents evidencing the agreement between
transferor and transferee as to the transfer of registered shares.
Repurchase of Company shares
The Company may repurchase its own shares in the cases and subject to the conditions set by the Luxembourg
Company Law and, in the case of acquisitions of shares or ADSs made through a stock exchange in which shares or ADSs
are traded, with any applicable laws and regulations of such market. Please see “Purchase of Equity Securities by the
Issuer and Affiliated Purchasers” for further information on the authorization granted on June 2, 2020, by the annual
general meeting of shareholders to the Company or its subsidiaries to repurchase shares of the Company, including
shares represented by ADSs.
Limitation on Securities Ownership
There are no limitations currently imposed by Luxembourg law or the articles of association on the rights of the
Company’s non-resident or foreign shareholders to hold or vote the Company’s shares.
Change in Control
None of our outstanding securities has any special control rights. The Company’s articles of association do not contain
any provision that would have the effect of delaying, deferring or preventing a change in control of the Company and
that would operate only with respect to a merger, acquisition or corporate restructuring involving the Company or any
of its subsidiaries. In addition, the Company does not know of any significant agreements or other arrangements to
which the Company is a party and which take effect, alter or terminate in the event of a change of control of the
Company. There are no agreements between the Company and members of its board of directors or employees
providing for compensation if they resign or are made redundant without reason, or if their employment ceases
following a change in control of the Company.
There are no rights associated with the Company’s shares other than those described above.
Ownership Disclosure
The Company’s articles of association do not contain any provision requiring disclosure of share ownership. However,
under the Luxembourg Transparency Law investors in the Company’s securities should notify the Company and the
Luxembourg securities commission on an ongoing basis whenever the proportion of voting rights held or controlled by
any such investor reaches, exceeds or falls below any of the following thresholds: 5%, 10%, 15%, 20%, 25%, 33.33%,

Graphics
Annual Report 2022
124
50% and 66.66%. Failure to notify the Company and the Luxembourg securities commission of the reaching or crossing
of any such thresholds may result in the suspension of the voting rights attaching to the shares exceeding the threshold
which would have had to be notified.
Diversity and Inclusion
The Company’s Code of Conduct prohibits unlawful discrimination in employment relationships, granting all people the
right to apply for a position in Tenaris, or to be considered for a new position based on merit, without arbitrary
discrimination. The Company’s Human Resources Policy champions equal opportunities by ensuring that hiring,
promotion, transfer, notice periods, dialogue, rights and protection, as well as other employment decisions are taken
without regard for race, color, religious belief, gender, age, disability, national origin or sexual orientation.
Compensation and remuneration are based on each person’s duties, personal performance, competence and behavior.
Tenaris pursues a policy of inclusive corporate culture and leadership, recognizing the range of benefits brought by
embracing diversity in all its aspects, from gender to nationality and age. Specifically, we are making headway in our
drive to improve the gender balance, in the knowledge that tackling the male-dominated traditions prevalent in the
steel industry will contribute positively to our performance culture.
Summary of differences with NYSE standards
As a Luxembourg company listed on the NYSE, the Bolsa Mexicana de Valores, S.A. de C.V. (the Mexican Stock
Exchange), and the Borsa Italiana S.p.A. (the Italian Stock Exchange), the Company is required to comply with some, but
not all, of the corporate governance standards of these exchanges. The Company, however, believes that its corporate
governance practices meet, in all material respects, the corporate governance standards that are generally required for
controlled companies by all of the exchanges on which the Company’s securities trade.
The following is a summary of the significant ways that the Company’s corporate governance practices differ from the
corporate governance standards required for foreign controlled companies by the NYSE. The Company’s corporate
governance practices may differ in non-material ways from certain other standards required by the NYSE that are not
detailed here.
Non-management directors’ meetings
Under NYSE standards, non-management directors must meet at regularly scheduled executive sessions without
management present and, if such group includes directors who are not independent, a meeting should be scheduled
once per year including only independent directors. Neither Luxembourg law nor the Company’s articles of association
require the holding of such meetings and the Company does not have a set policy for these meetings. For additional
information on board meetings, see “Directors, Senior Management and Employees Directors and Senior
Management Board of Directors”.
In addition, NYSE-listed companies are required to provide a method for interested parties to communicate directly
with non-management directors as a group. While the Company does not have such a method, it has set up a
compliance line for investors and other interested parties to communicate their concerns directly to the members of
our audit committee, all of whom are non-management, independent directors.
Audit committee composition
Under NYSE standards, listed U.S. companies are required to have an audit committee composed of independent
directors that satisfy the requirements of Rule 10A-3 promulgated under the Exchange Act. Pursuant to the Company’s
articles of association, as supplemented by the audit committee’s charter, for as long as the Company’s shares are
listed on at least one regulated market, the Company must have an audit committee composed of at least three
members, the majority of whom must qualify as independent directors (as defined in the Company’s articles of
association), provided, however, that the composition and membership of the audit committee shall satisfy such
requirements as are applicable to, and mandatory for, audit committees of issuers such as the Company under any law,
rule or regulation applicable to the Company (including, without limitation, the applicable laws, rules and regulations of
such regulated market or markets). The Company’s audit committee, which currently consists of four members,
complies with such requirements. In accordance with NYSE standards, the Company has an audit committee entirely
composed of independent directors for purposes of the Exchange Act Rule 10A-3(b)(1). For more information on the
Company’s audit committee see “Directors, Senior Management and Employees Board Practices Audit Committee”.

Graphics
Annual Report 2022
125
Under NYSE standards, all audit committee members of listed U.S. companies are required to be financially literate or
must acquire such financial knowledge within a reasonable period and at least one of its members shall have
experience in accounting or financial administration. In addition, if a member of the audit committee is simultaneously
a member of the audit committee of more than three public companies, and the listed company does not limit the
number of audit committees on which its members may serve, then in each case the board must determine whether
the simultaneous service would prevent such member from effectively serving on the listed company’s audit committee
and shall publicly disclose its decision. Luxembourg law provisions on audit committee membership require only that at
least one member of the audit committee have competence in accounting or auditing matters. The board of directors
of the Company has determined that Ms. Tiuba, the committee’s chairperson, qualifies as “audit committee financial
expert” under applicable SEC rules and has competence in accounting or auditing matters, as required by applicable
Luxembourg law. In addition, the membership of the audit committee as a whole has sufficient relevant knowledge of
the business and financial experience to properly discharge its functions. The audit committee has the authority, from
time to time and as it deems necessary, to engage persons that meet all of the attributes of a financial expert as
consultants. See “Audit Committee Financial Expert”.
Standards for evaluating director independence
Under NYSE standards, the board is required, on a case-by-case basis, to express an opinion with regard to the
independence or lack of independence of each individual director. Neither Luxembourg law nor the Company’s articles
of association requires that the board of directors express such an opinion. In addition, the definition of “independent”
under the NYSE rules differs in some non-material respects from the definition contained in the Company’s articles of
association. For more information on the Company’s independent directors and the definition of “independent” under
the Company’s articles of association see “Directors, Senior Management and Employees Directors and Senior
Management Board of Directors” and “Directors, Senior Management and Employees Board Practices Audit
Committee”.
Audit committee responsibilities
Pursuant to the Company’s articles of association, the audit committee shall assist the board of directors in fulfilling its
oversight responsibilities relating to the integrity of its consolidated financial statements, the effectiveness of its
systems of internal control, risk management and internal audit over financial reporting and the independence and
performance of the external auditors. The audit committee is required to review and, where applicable, approve
material transactions between the Company or its subsidiaries and related parties and also perform the other duties
entrusted to it by the board. The NYSE requires certain matters to be set forth in the audit committee charter of U.S.
listed companies.
The Company’s audit committee charter provides for many of the responsibilities that are expected from such bodies
under the NYSE standard and in accordance with applicable Luxembourg law, including the Audit Reform Law; however,
due to the Company’s equity structure and holding company nature, the charter does not contain all such
responsibilities, including provisions related to procedures for the receipt and treatment of complaints (although the
Company has established such procedures), funding for payment of administrative expenses and compensation to
advisors (although the audit committee has the authority to engage outside advisors), setting hiring policies for
employees or former employees of external auditors, and an annual performance evaluation of the audit committee.
For more information on the Company’s audit committee see “Directors, Senior Management and Employees Board
Practices Audit Committee”.
Standards for approval of related-party transactions
The Company is subject to Luxembourg laws governing approval and disclosure of material related party transactions,
including the Shareholders’ Rights Law; and the Company’s articles of association and the Audit Committee charter
require the Audit Committee to review material transactions with related parties to determine whether their terms are
consistent with the interests of the Company and its shareholders and with market conditions. In addition, recently
amended NYSE standard on related-party transactions requires all NYSE-listed companies’ audit committees (or
another independent body of the board of directors) to conduct a reasonable prior review and oversight of all related
party transactions for potential conflicts of interest and to prohibit such a transaction if it determines it to be
inconsistent with the interests of the company and its shareholders. The rule defines the term “related party
transaction” by reference to the disclosure requirements for annual reports under the Exchange Act. The materiality
threshold applicable to foreign private issuers differs to the one applicable to U.S companies. For further details on the

Graphics
Annual Report 2022

approval process for related party transactions, see “Directors, Senior Management and Employees Board Practices
Audit Committee”.
Shareholder voting on equity compensation plans
Under NYSE standards, shareholders must be given the opportunity to vote on equity-compensation plans and material
revisions thereto, except for employment inducement awards, certain grants, plans and amendments in the context of
mergers and acquisitions, and certain specific types of plans. The Company does not currently offer equity-based
compensation to its directors, senior management or employees, and therefore does not have a policy on this matter.
For more information on directors’ compensation see “Directors, Senior Management and Employees
Compensation”.
The Shareholders’ Rights Law requires the Company to adopt a Compensation Policy setting forth the principles and
guidelines for purposes of determining the compensation payable to the members of the Company’s board of directors
and the managing director or chief executive officer. Such Compensation Policy must be submitted to the non-binding
vote of the shareholders. In addition, the Shareholders’ Rights Law provides that the Company must prepare an annual
report describing the compensation paid to directors and the chief executive officer for the performance of their duties
and submit such report to the shareholders for approval. The Compensation Policy and Compensation Report must be
available on the Company’s website. For more information on the Compensation Policy and the 2022 Compensation
Report see “Directors, Senior Management and Employees Compensation”.
Disclosure of corporate governance guidelines
NYSE-listed companies must adopt and disclose corporate governance guidelines. Neither Luxembourg law nor the
Company’s articles of association require the adoption or disclosure of corporate governance guidelines. The
Company’s board of directors follows corporate governance guidelines consistent with its equity structure and holding
company nature, but the Company has not codified them and therefore does not disclose them on its website.
Code of business conduct and ethics
Under NYSE standards, listed companies must adopt and disclose a code of business conduct and ethics for directors,
officers and employees, and promptly disclose any waivers of the code for directors or executive officers. Neither
Luxembourg law nor the Company’s articles of association require the adoption or disclosure of such a code of conduct.
The Company, however, has adopted a code of conduct that applies to all directors, officers and employees that is
posted on its website and which complies with the NYSE’s requirements, except that it does not require the disclosure
of waivers of the code for directors and officers. In addition, it has adopted a supplementary code of ethics for senior
financial officers, which is also posted on our website. See “Code of Ethics”.
Chief Executive Officer certification
A chief executive officer of a U.S. company listed on the NYSE must annually certify that he or she is not aware of any
violation by the company of NYSE corporate governance standards. In accordance with NYSE rules applicable to foreign
private issuers, the Company’s chief executive officer is not required to provide the NYSE with this annual compliance
certification. However, in accordance with NYSE rules applicable to all listed companies, the Company’s chief executive
officer must promptly notify the NYSE in writing after any of our executive officers becomes aware of any
noncompliance with any applicable provision of the NYSE’s corporate governance standards. In addition, the Company
must submit an executed written affirmation annually and an interim written affirmation upon the occurrence of any
of the events listed in the foreign private issuer interim written affirmation form by the NYSE.

Audit report
To the Shareholders of
Tenaris S.A.
Report on the audit of the consolidated financial statements
Our opinion
In our opinion, the accompanying consolidated financial statements give a true and fair view of the
consolidated financial position of Tenaris S.A. (the “Company”) and its subsidiaries (the “Group”) as at
31 December 2022, and of its consolidated financial performance and its consolidated cash flows for
the year then ended in accordance with International Financial Reporting Standards (IFRS) as issued
by the International Accounting Standards Board (IASB) and in accordance with IFRS as adopted by
the European Union.
Our opinion is consistent with our additional report to the Audit Committee of the Company’s Board of
Directors (the “Audit Committee”).
What we have audited
The Group’s consolidated financial statements comprise:
x the consolidated statement of financial position as at 31 December 2022;
x the consolidated income statement for the year then ended;
x the consolidated statement of comprehensive income for the year then ended;
x the consolidated statement of changes in equity for the year then ended;
x the consolidated statement of cash flows for the year then ended; and
x the notes to the consolidated financial statements, which include a summary of significant accounting
policies.
Basis for opinion
We conducted our audit in accordance with the EU Regulation No 537/2014, the Law of 23 July 2016
on the audit profession (Law of 23 July 2016) and International Standards on Auditing (ISAs) as issued
by the International Auditing and Assurance Standards Board (IAASB) and as adopted for Luxembourg
by the “Commission de Surveillance du Secteur Financier” (CSSF). Our responsibilities under the
EU Regulation No 537/2014, the Law of 23 July 2016 and ISAs as adopted for Luxembourg by the CSSF
are further described in the “Responsibilities of the “Réviseur d’entreprises agréé” for the audit of the
consolidated financial statements” section of our report.
We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for
our opinion.
We are independent of the Group in accordance with the International Code of Ethics for Professional
Accountants, including International Independence Standards, issued by the International Ethics
Standards Board for Accountants (IESBA Code) as adopted for Luxembourg by the CSSF together with
the ethical requirements that are relevant to our audit of the consolidated financial statements. We have
fulfilled our other ethical responsibilities under those ethical requirements.

To the best of our knowledge and belief, we declare that we have not provided non-audit services that
are prohibited under Article 5(1) of the EU Regulation No 537/2014.
The non-audit services that we have provided to the Company and its controlled undertakings, if
applicable, for the year ended 31 December 2022, are disclosed in Note 31 to the consolidated financial
statements.
Key audit matters
Key audit matters are those matters that, in our professional judgement, were of most significance in
our audit of the consolidated financial statements of the current period. These matters were addressed
in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion
thereon, and we do not provide a separate opinion on these matters.
Key audit matter
How our audit addressed the key audit matter
Impairment assessment of goodwill
The Group
s balance sheet includes
goodwill for an
amount of 1,085 million USD.
Goodwill is subject to at least an annual
impairment test or is tested more frequently
if events or circumstances indicate that its
carrying amount value may be impaired.
During the year, Management has tested for
impairment those cash generating units
(CGUs) containing
goodwill.
The impairment tests were important
to our audit as they involved significant
judgements and assumptions in the
assessment of the recoverable amounts of
the CGUs and required significant audit
effort
. The assumptions with the most
significant impact on the cash
-flow forecasts
were discount rate, growth rate, oil and gas
prices, average number of active oil and gas
drilling rigs and raw materials costs
.
The disclosures related to this matter are
included in Notes II.H, 5 and 11 to the
consolidated financial statements.
We evaluated and tested the effectiveness of controls
relating to management’s impairment assessment,
including controls over management’s analysis of
impairment indicators and controls over the review of
assumptions used and discounted cash flow
calculations.
In addition, we assessed the robustness of the
impairment indicators analysis and the cash flow
projections included in the impairment tests prepared
by Management. Our audit procedures included,
among others, the involvement of professionals with
specialised skills and knowledge to assist us in
evaluating certain assumptions and the valuation
methodology used by the Company.
We assessed the reasonableness of other
assumptions used in the cash flow projections by
comparing them to external and
historical data, when
available, such as analyst reports and evolution of rig
counts.
Moreover, we have
analysed sensitivities in the
valuation model, evaluating whether a reasonably
possible change in assumptions could cause the
carrying amount to exceed its recoverable amount.
We also compared actual cash flow results with
previous forecasts.
We finally assessed the adequacy of the disclosures
in the consolidated financial statements.

Other information
The Board of Directors is responsible for the other information. The other information comprises the
information stated in the annual report including the consolidated management report and the Corporate
Governance Statement but does not include the consolidated financial statements and our audit report
thereon.
Our opinion on the consolidated financial statements does not cover the other information and we do
not express any form of assurance conclusion thereon.
In connection with our audit of the consolidated financial statements, our responsibility is to read the
other information identified above and, in doing so, consider whether the other information is materially
inconsistent with the consolidated financial statements or our knowledge obtained in the audit, or
otherwise appears to be materially misstated. If, based on the work we have performed, we conclude
that there is a material misstatement of this other information, we are required to report that fact. We
have nothing to report in this regard.
Responsibilities of the Board of Directors and those charged with governance for the
consolidated financial statements
The Board of Directors is responsible for the preparation and fair presentation of the consolidated
financial statements in accordance with IFRSs as issued by the IASB and in accordance with IFRS as
adopted by the European Union, and for such internal control as the Board of Directors determines is
necessary to enable the preparation of consolidated financial statements that are free from material
misstatement, whether due to fraud or error.
In preparing the consolidated financial statements, the Board of Directors is responsible for assessing
the Group’s ability to continue as a going concern, disclosing, as applicable, matters related to going
concern and using the going concern basis of accounting unless the Board of Directors either intends
to liquidate the Group or to cease operations, or has no realistic alternative but to do so.
Those charged with governance are responsible for overseeing the Group’s financial reporting process.
The Board of Directors is responsible for presenting and marking up the consolidated financial
statements in compliance with the requirements set out in the Delegated Regulation 2019/815 on
European Single Electronic Format (ESEF Regulation).
Responsibilities of the “Réviseur d’entreprises agréé” for the audit of the consolidated financial
statements
The objectives of our audit are to obtain reasonable assurance about whether the consolidated financial
statements as a whole are free from material misstatement, whether due to fraud or error, and to issue
an audit report that includes our opinion.
Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in
accordance with the EU Regulation No 537/2014, the Law of 23 July 2016 and with ISAs as issued by
the IAASB and as adopted for Luxembourg by the CSSF will always detect a material misstatement
when it exists.

Graphics

Misstatements can arise from fraud or error and are considered material if, individually or in the
aggregate, they could reasonably be expected to influence the economic decisions of users taken on
the basis of these consolidated financial statements.
As part of an audit in accordance with the EU Regulation No 537/2014, the Law of 23 July 2016 and
with ISAs as adopted for Luxembourg by the CSSF, we exercise professional judgement and maintain
professional scepticism throughout the audit. We also:
identify and assess the risks of material misstatement of the consolidated financial statements,
whether due to fraud or error, design and perform audit procedures responsive to those risks, and
obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of
not detecting a material misstatement resulting from fraud is higher than for one resulting from error,
as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of
internal control;
obtain an understanding of internal control relevant to the audit in order to design audit procedures
that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Group’s internal control;
evaluate the appropriateness of accounting policies used and the reasonableness of accounting
estimates and related disclosures made by the Board of Directors;
conclude on the appropriateness of the Board of Directors’ use of the going concern basis of
accounting and, based on the audit evidence obtained, whether a material uncertainty exists related
to events or conditions that may cast significant doubt on the Group’s ability to continue as a going
concern. If we conclude that a material uncertainty exists, we are required to draw attention in our
audit report to the related disclosures in the consolidated financial statements or, if such disclosures
are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up
to the date of our audit report. However, future events or conditions may cause the Group to cease
to continue as a going concern;
evaluate the overall presentation, structure and content of the consolidated financial statements,
including the disclosures, and whether the consolidated financial statements represent the underlying
transactions and events in a manner that achieves fair presentation;
obtain sufficient appropriate audit evidence regarding the financial information of the entities and
business activities within the Group to express an opinion on the consolidated financial statements.
We are responsible for the direction, supervision and performance of the Group audit. We remain
solely responsible for our audit opinion.
We communicate with those charged with governance regarding, among other matters, the planned
scope and timing of the audit and significant audit findings, including any significant deficiencies in
internal control that we identify during our audit.
We also provide those charged with governance with a statement that we have complied with relevant
ethical requirements regarding independence and communicate to them all relationships and other
matters that may reasonably be thought to bear on our independence, and where applicable, actions
taken to eliminate threats or safeguards applied.

Graphics

From the matters communicated with those charged with governance, we determine those matters that
were of most significance in the audit of the consolidated financial statements of the current period and
are therefore the key audit matters. We describe these matters in our audit report unless law or
regulation precludes public disclosure about the matter.
We assess whether the consolidated financial statements have been prepared, in all material respects,
in compliance with the requirements laid down in the ESEF Regulation.
Report on other legal and regulatory requirements
The consolidated management report is consistent with the consolidated financial statements and has
been prepared in accordance with applicable legal requirements.
The Corporate Governance Statement is included in the consolidated management report. The
information required by Article 68ter Paragraph (1) Letters c) and d) of the Law of 19 December 2002
on the commercial and companies register and on the accounting records and annual accounts of
undertakings, as amended, is consistent with the consolidated financial statements and has been
prepared in accordance with applicable legal requirements.
We have been appointed as “Réviseur d’Entreprises Agréé” by the General Meeting of the Shareholders
on 3 May 2022 and the duration of our uninterrupted engagement, including previous renewals and
reappointments, is 21 years.
We have checked the compliance of the consolidated financial statements of the Group as at
31 December 2022 with relevant statutory requirements set out in the ESEF Regulation that are
applicable to consolidated financial statements.
For the Group it relates to the requirement that:
the consolidated financial statements are prepared in a valid XHTML format;
the XBRL markup of the consolidated financial statements uses the core taxonomy and the common
rules on markups specified in the ESEF Regulation.
In our opinion, the consolidated financial statements of the Group as at 31 December 2022 have
been prepared, in all material respects, in compliance with the requirements laid down in the
ESEF Regulation.

143



I. GENERAL INFORMATION
Tenaris S.A. (the “Company”) was established as a public limited liability company (société anonyme) under the laws of
the Grand-Duchy of Luxembourg on December 17, 2001. The Company holds, either directly or indirectly, controlling
interests in various subsidiaries in the steel pipe manufacturing and distribution businesses. References in these
Consolidated Financial Statements to “Tenaris” refer to the Company and its consolidated subsidiaries. A list of the
principal Company’s subsidiaries is included in note 32 to these Consolidated Financial Statements.
The Company’s shares trade on the Italian Stock Exchange and the Mexican Stock Exchange; and the Company’s American
Depositary Securities (“ADS”) trade on the New York Stock Exchange.
These Consolidated Financial Statements were approved for issuance by the Company’s Board of Directors on February
15, 2023.





II. ACCOUNTING POLICIES
The principal accounting policies applied in the preparation of these Consolidated Financial Statements are set out below.
These policies have been consistently applied to all the years presented, unless otherwise stated.

A Basis of presentation
The Consolidated Financial Statements of Tenaris have been prepared in accordance with International Financial
Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (“IASB”) and in accordance with
IFRS as adopted by the European Union, under the historical cost convention, as modified by the revaluation of certain
financial assets and liabilities (including derivative instruments) and plan assets at fair value. The Consolidated Financial
Statements are, unless otherwise noted, presented in thousands of U.S. dollars (“$”).
Whenever necessary, certain comparative amounts have been reclassified to conform to changes in presentation in the
current year.
The preparation of Consolidated Financial Statements in conformity with IFRS requires management to make certain
accounting estimates and assumptions that might affect among others, the reported amounts of assets, liabilities,
contingent liabilities, revenues and expenses. Actual results may differ from these estimates. The main areas involving
significant estimates or judgements are: impairment of goodwill and long-lived assets (notes II.H), impairment in
investments in associates (note II.B); income taxes (note II.O); obsolescence of inventory (note II.J); contingencies (note
II.Q); allowance for trade receivables (note II.K); post-employment and other long-term benefits (note II.P); business
combinations (notes II.B); useful lives of property, plant and equipment and other long-lived assets (notes II.E, II.F, II.H);
fair value estimation of certain financial instruments (notes III.B, IV.34) and property title ownership restriction (note
IV.27). During the year there were no material changes in the significant accounting estimates and judgements.
(1) Accounting pronouncements applicable as from January 1, 2022
Accounting pronouncements that became effective during 2022 have no material effect on the Company’s financial
condition or results of operations.
(2) New accounting pronouncements not applicable as of December 31, 2022
Certain newly published accounting standards, amendments to accounting standards and interpretations are not
mandatory for December 31, 2022 reporting periods and have not been early adopted by the Company. These standards,
amendments or interpretations are not expected to have a material impact in the current or future reporting periods and
on foreseeable future transactions.

B Group accounting






(1) Subsidiaries and transactions with non-controlling interests
Subsidiaries are all entities over which Tenaris has control. Tenaris controls an entity when it is exposed to, or has rights
to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over
the entity. Subsidiaries are fully consolidated from the date on which control is exercised by the Company and are no
longer consolidated from the date control ceases.

The acquisition method of accounting is used to account for the acquisition of subsidiaries by Tenaris. The cost of an
acquisition is measured as the fair value of the assets transferred, equity instruments issued and liabilities incurred or
assumed at the date of exchange. Acquisition-related costs are expensed as incurred. Identifiable assets acquired,
liabilities and contingent liabilities assumed in a business combination are generally measured initially at their fair values
at the acquisition date. Any non-controlling interest in the acquiree is measured either at fair value or at the non-
controlling interest’s proportionate share of the acquiree’s net identifiable assets. The excess of the aggregate of the
consideration transferred and the amount of any non-controlling interest in the acquiree over the fair value of the
identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary
acquired, the difference is recognized directly in the Consolidated Income Statement.

Contingent consideration is classified either as equity or as a financial liability. Amounts classified as a financial liability
are subsequently remeasured to fair value with changes in fair value recognized in profit or loss.
If the business combination is achieved in stages, the acquisition date carrying value of the acquirer’s previously held
equity interest in the acquiree is remeasured to fair value at the acquisition date. Any gains or losses arising from such
remeasurement are recognized in profit or loss.

Transactions with non-controlling interests that do not result in a loss of control are accounted as transactions with equity
owners of the Company. For purchases from non-controlling interests, the difference between any consideration paid
and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses
on disposals to non-controlling interests are also recorded in equity.

When the Company ceases to have control or significant influence, any retained interest in the entity is remeasured to
its fair value, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount
for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In
addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for
as if the group had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized
in other comprehensive income are reclassified to profit or loss.
Material intercompany transactions, balances and unrealized gains (losses) on transactions between Tenaris subsidiaries
have been eliminated in consolidation. However, since the functional currency of some subsidiaries is its respective local
currency, some financial gains (losses) arising from intercompany transactions are generated. These are included in the
Consolidated Income Statement under Other financial results.

(2) Non-consolidated companies
Non-consolidated companies are all entities in which Tenaris has significant influence but not control, generally
accompanying a shareholding of between 20% and 50% of the voting rights. Investments in non-consolidated companies
(associates and joint ventures) are accounted for by the equity method of accounting and are initially recognized at cost
(as defined by IAS 28, “Investments in Associates and Joint Ventures”). The Company’s investment in non-consolidated
companies includes goodwill identified in acquisition, net of any accumulated impairment loss.
Under the equity method of accounting, the investments are initially recognized at cost and adjusted thereafter to
recognize Tenaris’s share of the post-acquisition profits or losses of the investee in profit or loss, and Tenaris’s share of
movements in other comprehensive income of the investee in other comprehensive income. Dividends received or
receivable from associates and joint ventures are recognized as a reduction in the carrying amount of the investment.

145





If material, unrealized results on transactions between Tenaris and its non-consolidated companies are eliminated to the
extent of Tenaris’s interest in the non-consolidated companies. Unrealized losses are also eliminated unless the
transaction provides evidence of an impairment indicator of the asset transferred. Financial statements of non-
consolidated companies are adjusted where necessary to ensure consistency with IFRS.
The Company’s pro-rata share of earnings in non-consolidated companies is recorded in the Consolidated Income
Statement under Equity in earnings of non-consolidated companies. The Company’s pro-rata share of changes in other
comprehensive income is recognized in the Consolidated Statement of Comprehensive Income.
a) Ternium
At December 31, 2022, Tenaris held 11.46% of Ternium S.A. (“Ternium”) common stock. The following factors and
circumstances evidence that Tenaris has significant influence over Ternium:
Both the Company and Ternium are under the indirect common control of San Faustin S.A. (“San Faustin”);
Four out of nine members of Ternium’s Board of Directors (including Ternium’s Chairman) are also members of the
Company’s Board of Directors;
Under the shareholders’ agreement by and between the Company and Techint Holdings S.àr.l, a wholly owned
subsidiary of San Faustin and Ternium’s main shareholder, dated January 9, 2006, Techint Holdings S.àr.l, is required
to take actions within its power to cause (a) one of the members of Ternium’s Board of Directors to be nominated
by the Company and (b) any director nominated by the Company to be removed from Ternium’s Board of Directors
only pursuant to previous written instructions of the Company.
b) Usiminas
At December 31, 2022, Tenaris held, through its Brazilian subsidiary Confab Industrial S.A. (“Confab”), 36.5 million
ordinary shares and 1.3 million preferred shares of Usinas Siderúrgicas de Minas Gerais S.A. - Usiminas (“Usiminas”),
representing 5.19% of its shares with voting rights and 3.07% of its total share capital.
Confab’s acquisition of the Usiminas shares was part of a larger transaction performed on January 16, 2012, pursuant
to which Tenaris’s affiliate Ternium (through certain of its subsidiaries) and Confab acquired a large block of Usiminas
ordinary shares and joined Usiminas’ existing control group. Subsequently, in 2016, Ternium and Confab subscribed to
additional ordinary shares and to preferred shares.
At December 31, 2022, the Usiminas control group held, in the aggregate, 483.6 million ordinary shares bound to the
Usiminas shareholders’ agreement, representing approximately 68.6% of Usiminas’ voting capital. The Usiminas control
group, which is bound by a long-term shareholders’ agreement that governs the rights and obligations of Usiminas’
control group members, is currently composed of three sub-groups: the T/T Group, comprising Confab and certain
Ternium entities; the NSC Group, comprising Nippon Steel Corporation (“NSC”), Metal One Corporation and Mitsubishi
Corporation; and Usiminas’ pension fund Previdência Usiminas. The T/T Group holds approximately 47.1% of the total
shares held by the control group (39.5% corresponding to the Ternium entities and the other 7.6% corresponding to
Confab); the NSC Group holds approximately 45.9% of the total shares held by the control group; and Previdência
Usiminas holds the remaining 7%.
The corporate governance rules reflected in the Usiminas shareholders agreement include, among others, an
alternation mechanism for the nomination of each of the Chief Executive Officer (“CEO”) and the Chairman of the Board
of Directors of Usiminas, as well as a mechanism for the nomination of other members of Usiminas’ executive board.
The Usiminas shareholders agreement also provides for an exit mechanism consisting of a buy-and-sell procedure
(exercisable at any time after November 16, 2022, and applicable with respect to shares held by NSC and the T/T Group),
which would allow either Ternium or NSC to purchase all or a majority of the Usiminas shares held by the other
shareholder.
Confab and the Ternium entities party to the Usiminas shareholders agreement have a separate shareholders
agreement governing their respective rights and obligations as members of the T/T Group. Such separate agreement
includes, among others, provisions granting Confab certain rights relating to the T/T Group’s nomination of Usiminas’
officers and directors under the Usiminas shareholders agreement. Those circumstances evidence that Tenaris has
significant influence over Usiminas.

c) Techgen
Techgen S.A. de C.V. (“Techgen”), which operates an electric power plant in Mexico, is a joint venture company owned
48% by Ternium, 30% by Tecpetrol International S.A. (“Tecpetrol”) and 22% by Tenaris. The Company, Ternium and
Tecpetrol are parties to a shareholders’ agreement relating to the governance of Techgen and are under the indirect
common control of San Faustin. Based on the facts stated above, the Company has determined that it has significant
influence over this entity.
d) Global Pipe Company
Global Pipe Company (“GPC”) is a Saudi-German joint venture, established in 2010 and located in Jubail, Saudi Arabia,
which manufactures LSAW pipes. Tenaris, through its subsidiary Saudi Steel Pipe Company (“SSPC”), currently owns
35% of the share capital of GPC. In accordance with GPC’s bylaws, SSPC’s 35% equity interest entitles SSPC to appoint
four of the eleven members of the Board of Directors of GPC. In addition, SSPC has the ability to block any shareholder
resolution. Based on the facts stated above, the Company has determined that it has significant influence over this
entity.
Tenaris carries its investments in non-consolidated companies under the equity method, with no additional goodwill or
intangible assets recognized. Tenaris reviews investments in non-consolidated companies for impairment whenever
events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. For more
information see note 13 to these Consolidated Financial Statements.




C Segment information
The Company is organized in one major business segment, Tubes, which is also the reportable operating segment. All
other business activities and operating segments that are not required to be separately reported, are disclosed in the
Other segment.
The Tubes segment includes the production and sale of both seamless and welded steel tubular products and related
services mainly for the oil and gas industry, particularly oil country tubular goods (“OCTG”) used in drilling operations,
and for other industrial applications with production processes that consist in the transformation of steel into tubular
products. Business activities included in this segment are mainly dependent on the oil and gas industry worldwide, as this
industry is a major consumer of steel pipe products, particularly OCTG used in drilling activities. Demand for steel pipe
products from the oil and gas industry has historically been volatile and depends primarily upon the number of oil and
natural gas wells being drilled, completed and reworked, and the depth and drilling conditions of these wells. Sales are
generally made to end users, with exports being done through a centrally managed global distribution network and
domestic sales are made through local subsidiaries.
The Other segment includes all business activities related to the production and selling of sucker rods, industrial
equipment, coiled tubing, tubes used for plumbing applications, oilfield / hydraulic fracturing services, energy and raw
materials that exceed internal requirements.
Tenaris’s Chief Operating Decision Maker (“CODM”) holds monthly meetings with senior management, in which
operating and financial performance information is reviewed. This information differs from IFRS principally as follows:
The use of direct cost methodology to calculate the inventories, while under IFRS it is at full cost, including absorption
of production overheads and depreciations;
The use of costs based on previously internally defined cost estimates, while, under IFRS, costs are calculated at
historical cost, mainly on a FIFO basis;
Any currency translation adjustment reclassification, when applicable, for companies that under IFRS had a different
functional currency than the U.S. dollar;
Other timing differences, if any.
Tenaris presents its geographical information in five areas: North America, South America, Europe, Middle East and Africa
and Asia Pacific. For purposes of reporting geographical information, net sales are allocated to geographical areas based
on the customer’s location; allocation of assets, capital expenditures and associated depreciations and amortizations are
based on the geographical location of the assets.

D Foreign currency translation
(1) Functional and presentation currency
IAS 21 (revised), “The effects of changes in foreign exchange rates” defines the functional currency as the currency of the
primary economic environment in which an entity operates.
The functional and presentation currency of the Company is the U.S. dollar. The U.S. dollar is the currency that best
reflects the economic substance of the underlying events and circumstances relevant to Tenaris’s global operations.
Starting January 1, 2023, the Company changed the functional currency of its Brazilian subsidiaries, from the Brazilian
Real to the U.S. dollar.
This decision is a result of a significant increase of its Brazilian Subsidiaries’ participation in the OCTG and line pipe
international markets, a trend which started in recent years and has been strengthened in 2022, an increased level of
integration of the local operations within Tenaris’s international commercial and supply chain system, as well as the fact
that the main purchase agreement contracts and the long term sales agreement contracts with major international and
local oil companies are both indexed to the U.S. dollar. Local steel prices are also being affected by the U.S. dollar /
Brazilian Real fluctuations.
As a result of this change, except for the Italian subsidiaries whose functional currency is the Euro, Tenaris determined
that the functional currency of its other subsidiaries is the U.S. dollar, based on the following principal considerations:
Sales are mainly negotiated, denominated and settled in U.S. dollars. If priced in a currency other than the U.S. dollar,
the sales price may consider exposure to fluctuation in the exchange rate against the U.S. dollar;
Prices of their critical raw materials and inputs are priced and / or settled in U.S. dollars;
Transaction and operational environment and the cash flow of these operations have the U.S. dollar as reference
currency;
Significant level of integration of the local operations within Tenaris’s international global distribution network;
Net financial assets and liabilities are mainly received and maintained in U.S. dollars;
The exchange rate of certain legal currencies has long-been affected by recurring and severe economic crises.

(2) Transactions in currencies other than the functional currency
Transactions in currencies other than the functional currency are translated into the functional currency using the
exchange rates prevailing at the date of the transactions or valuation where items are re-measured.
At the end of each reporting period: (i) monetary items denominated in currencies other than the functional currency
are translated using the closing rates; (ii) non-monetary items that are measured in terms of historical cost in a currency
other than the functional currency are translated using the exchange rates prevailing at the date of the transactions; and
(iii) non-monetary items that are measured at fair value in a currency other than the functional currency are translated
using the exchange rates prevailing at the date when the fair value was determined.
Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-
end exchange rates of monetary assets and liabilities denominated in currencies other than the functional currency are
recorded as gains and losses from foreign exchange and included in Other financial results in the Consolidated Income
Statement, except when deferred in equity as qualifying cash flow hedges and qualifying net investment hedges.

148



(3) Translation of financial information in currencies other than the functional currency
Results of operations for subsidiaries whose functional currencies are not the U.S. dollar are translated into U.S. dollars
at the average exchange rates for each quarter of the year. Financial statement positions are translated at the year-end
exchange rates. Translation differences are recognized in a separate component of equity as currency translation
adjustments. In the case of a sale or other disposal of any of such subsidiaries, any accumulated translation difference
would be recognized in the Consolidated Income Statement as a gain or loss from the sale following IAS 21.
Goodwill and fair value adjustments arising from the acquisition of a foreign operation are treated as assets and liabilities
of the foreign operation and translated at the closing rate.



E Property, plant and equipment
Property, plant and equipment are recognized at historical acquisition or construction cost less accumulated depreciation
and impairment losses. Historical cost includes expenditure that is directly attributable to the acquisition of the items.
Property, plant and equipment acquired through acquisitions accounted for as business combinations have been valued
initially at the fair market value of the assets acquired.
Major overhaul and rebuilding expenditures are capitalized as property, plant and equipment only when it is probable
that future economic benefits associated with the item will flow to the Company and the investment enhances the
condition of assets beyond its original condition. The carrying amount of the replaced part is derecognized. Maintenance
expenses on manufacturing properties are recorded as cost of products sold in the year in which they are incurred.
Cost may also include transfers from equity of any gains or losses on qualifying cash flow hedges of foreign currency
purchases of property, plant and equipment.
Borrowing costs that are attributable to the acquisition or construction of certain capital assets are capitalized as part of
the cost of the asset, in accordance with IAS 23 (revised), “Borrowing Costs”. Assets for which borrowing costs are
capitalized are those that require a substantial period of time to prepare for their intended use.

The depreciation method is reviewed at each year end. Depreciation is calculated using the straight-line method to
depreciate the cost of each asset to its residual value over its estimated useful life, as follows:
Land
No Depreciation
Buildings and improvements
30-50 years
Plant and production equipment
10-40 years
Vehicles, furniture and fixtures, and other equipment
4-10 years

The assets’ residual values and useful lives of significant plant and production equipment are reviewed and adjusted, if
appropriate, at each year-end date. An asset’s carrying amount is written down immediately to its recoverable amount
if the asset’s carrying amount is greater than its estimated recoverable amount.
Management’s re-estimation of assets useful lives, performed in accordance with IAS 16, “Property, Plant and
Equipment”, resulted in additional depreciation expenses of approximately $39 million for 2022, of $45 million for 2020
and did not materially affect depreciation expenses for 2021.
Tenaris depreciates each significant part of an item of property, plant and equipment for its different production facilities
that (i) can be properly identified as an independent component with a cost that is significant in relation to the total cost
of the item, and (ii) has a useful operating life that is different from another significant part of that same item of property,
plant and equipment.
Gains and losses on disposals are determined by comparing the proceeds with the carrying amount of assets and are
recognized under Other operating income or Other operating expenses in the Consolidated Income Statement.

F Intangible assets
(1) Goodwill
Goodwill represents the excess of the acquisition cost over the fair value of Tenaris’s share of net identifiable assets
acquired as part of business combinations determined mainly by independent valuations. Goodwill is tested at least
annually for impairment and carried at cost less accumulated impairment losses. Impairment losses on goodwill are not
reversed. Goodwill is included in the Consolidated Statement of Financial Position under Intangible assets, net.
For the purpose of impairment testing, goodwill is allocated to a cash generating unit (“CGU”) or group of CGUs that are
expected to benefit from the business combination which generated the goodwill being tested.




(2) Information systems projects
Costs associated with maintaining computer software programs are generally recognized as an expense as incurred.
However, costs directly related to the development, acquisition and implementation of information systems are
recognized as intangible assets if it is probable that they have economic benefits exceeding one year and comply with
the recognition criteria of IAS 38, Intangible Assets”.
Information systems projects recognized as assets are amortized using the straight-line method over their useful lives,
generally not exceeding a period of 3 years. Amortization charges are mainly classified as Selling, general and
administrative expenses in the Consolidated Income Statement.
Management’s re-estimation of assets useful lives, performed in accordance with IAS 38, did not materially affect
amortization expenses for 2022 and 2021 and resulted in additional amortization expenses of $11.1 million for 2020.

(3) Licenses, patents, trademarks and proprietary technology
Licenses, patents, trademarks, and proprietary technology acquired in a business combination are initially recognized at
fair value at the acquisition date. Licenses, patents, proprietary technology and those trademarks that have a finite useful
life are carried at cost less accumulated amortization. Amortization is calculated using the straight-line method to allocate
the cost over their estimated useful lives, which are in the range between 3 and 10 years. Amortization charges are mainly
classified as Cost of Sales in the Consolidated Income Statement.
The balance of acquired trademarks that have indefinite useful lives according to external appraisal amounts to $86.7
million at December 31, 2022, 2021 and 2020, and are included in Hydril CGU. Main factors considered in the
determination of the indefinite useful lives include the years that they have been in service and their recognition among
customers in the industry.
Management’s re-estimation of assets useful lives, performed in accordance with IAS 38, did not materially affect
amortization expenses for 2022, 2021 and 2020.



(4) Research and development
Research expenditures as well as development costs that do not fulfill the criteria for capitalization are recorded as Cost
of sales in the Consolidated Income Statement as incurred. Research and development expenditures included in Cost of
sales for the years 2022, 2021 and 2020 totaled $50.7 million, $45.3 million and $41.8 million, respectively.
Capitalized costs were not material for the years 2022, 2021 and 2020.


(5) Customer relationships
In accordance with IFRS 3, "Business Combinations" and IAS 38, Tenaris has recognized the value of customer relationships
separately from goodwill attributable to the acquisition of Maverick Tube Corporation (“Maverick”) and Hydril Company
(“Hydril”) groups, as well as the more recent acquisitions of SSPC and Ipsco Tubulars Inc. (“IPSCO”).





Graphics
Consolidated Financial Statements
For the years ended 2022, 2021 and 2020 - all amounts in thousands of U.S. dollars, unless otherwise stated
150








Customer relationships acquired in a business combination are recognized at fair value at the acquisition date, have a finite
useful life and are carried at cost less accumulated amortization. Amortization is calculated using the straight line method
over the initial expected useful lives which were approximately 14 years for Maverick, 10 years for Hydril, 9 years for SSPC
and 3 years for IPSCO.
In 2022, the Company has reviewed the useful life of SSPC’s customer relationships and decided to reduce it from 5 years to
3 years, consequently a higher amortization charge of approximately $4.1 million was recorded in the Consolidated Income
Statement under Selling, general and administrative expenses for the year ended December 31, 2022.
Management’s re-estimation of assets useful lives, performed in accordance with IAS 38, did not affect amortization
expenses for 2021 and 2020.
As of December 31, 2022 the net book value of SSPC’s customer relationship amounts to $41.5 million, with a residual useful
life of 3 years, while IPSCO’s, Maverick’s and Hydril’s customer relationships are fully amortized.



G Right-of-use assets and lease liabilities
Leases are recognized as a right-of-use asset and a corresponding liability at the date at which the leased asset is available
for use by the group. Each lease payment is allocated between the liability and finance cost. The finance cost is charged
to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of
the liability for each period. The right-of-use asset is depreciated over the lease term on a straight-line basis.
Lease liabilities include the net present value of i) fixed payments, less any lease incentives receivable, ii) variable lease
payments that are based on an index or a rate, iii) amounts expected to be payable by the lessee under residual value
guarantees, iv) the exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and v)
payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option.
The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be determined, the
lessee’s incremental borrowing rate is used, being the rate that the lessee would have to pay to borrow the funds
necessary to obtain an asset of similar value in a similar economic environment with similar terms and conditions.
Right-of-use assets are measured at cost comprising the amount of the initial measurement of lease liability, any lease
payments made at or before the commencement date less any lease incentives received and any initial direct costs
incurred by the lessee.
In determining the lease term, management considers all facts and circumstances that create an economic incentive to
exercise an extension option or early termination, or not to exercise a termination option. Extension options (or periods
after termination options) are only included in the lease term if the lease is reasonably certain to be extended (or not
terminated).
Payments associated with short-term leases, variable leases and leases of low value assets are recognized on a straight-
line basis as expenses in profit or loss. Short-term leases are leases with a lease term of 12 months or less.


H Impairment of non-financial assets
Long-lived assets including identifiable intangible assets are reviewed for impairment at the lowest level for which there
are separately identifiable cash flows (CGU). Most of the Company’s principal subsidiaries that constitute a CGU have a
single main production facility and, accordingly, each of such subsidiaries represents the lowest level of asset aggregation
that generates largely independent cash inflows.
Assets that are subject to amortization or depreciation are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount may not be recoverable. Intangible assets with indefinite useful lives,
including goodwill, are subject to at least an annual impairment test, or are tested more frequently if events or
circumstances indicate that the carrying amount value may be impaired. In some circumstances where there have not
been significant changes to CGU assets and liabilities as well as external and internal events which could materially alter
the recoverable amount of the CGU, the most recent detailed calculation of recoverable amount made in a preceding
period may be used in the impairment test for that CGU in the current period.

151




In assessing whether there is any indication that a CGU may be impaired, external and internal sources of information
are analyzed. Material facts and circumstances specifically considered in the analysis usually include the discount rate
used in Tenaris’s cash flow projections and the business condition in terms of competitive, economic and regulatory
factors, such as the cost of raw materials, oil and gas prices, and the evolution of the rig count.
An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount.
The recoverable amount is the higher between the asset’s value in use and fair value less costs of disposal. Any
impairment loss is allocated to reduce the carrying amount of the assets of the CGU in the following order:
(a) first, to reduce the carrying amount of any goodwill allocated to the CGU; and
(b) then, to the other assets of the unit (group of units) pro-rata on the basis of the carrying amount of each asset in
the unit (group of units), considering not to reduce the carrying amount of the asset below the highest of its fair
value less cost of disposal, its value in use or zero.
Value in use is calculated by discounting the estimated cash flows over a five year period (or higher if the period can be
justified) based on forecasts approved by management. For the subsequent years beyond the five-year period, a terminal
value is calculated based on perpetuity considering a nominal growth rate of 2% taking into account among others, mainly
the historical inflation rate.
For purposes of calculating the fair value less costs of disposal, Tenaris uses the estimated value of future cash flows that
a market participant could generate from the corresponding CGU.
Management judgment is required to estimate discounted future cash flows. Actual cash flows and values could vary
significantly from the forecasted future cash flows and related values derived using discounting techniques.
Non-financial assets other than goodwill that suffered an impairment are reviewed for possible reversal at each reporting
date. For more information on impairment charges see note 5 to these Consolidated Financial Statements.


I Other investments
Other investments consist primarily of investments in financial instruments and time deposits with a maturity of more
than three months at the date of purchase.
Certain non-derivative financial assets that the Company held not for trading have been categorized as financial assets at
fair value through other comprehensive income (“FVOCI”), as the business model objective is achieved by both holding
financial assets in order to collect contractual cash flows and selling financial assets. They are carried at fair value and
interest income from these financial assets is included in finance income using the effective interest rate method.
Unrealized gains or losses are recorded as a fair value adjustment in the Consolidated Statement of Comprehensive
Income and transferred to the Consolidated Income Statement when the financial asset is sold. Exchange gains and losses
and impairments related to the financial assets are immediately recognized in the Consolidated Income Statement. FVOCI
instruments with maturities greater than 12 months after the balance sheet date are included in non-current assets.
Other investments in financial instruments and time deposits are categorized as financial assets at fair value through
profit or loss (“FVPL”) because such investments are held for trading and their performance is evaluated on a fair value
basis. The results of these investments are recognized in Financial Results in the Consolidated Income Statement.

Purchases and sales of financial investments are recognized as of their settlement date.
The fair values of quoted investments are generally based on current bid prices. If the market for a financial investment is
not active or the securities are not listed, Tenaris estimates the fair value by using standard valuation techniques. See section
III Financial Risk Management.

J Inventories
Inventories are stated at the lower between cost and net realizable value. The cost of finished goods and goods in process
is comprised of raw materials, direct labor, utilities, freights and other direct costs and related production overhead costs,
and it excludes borrowing costs. The allocation of fixed production costs, including depreciation and amortization
charges, is based on the normal level of production capacity. Inventories cost is mainly based on the FIFO method. Tenaris
estimates net realizable value of inventories by grouping, where applicable, similar or related items. Net realizable value
is the estimated selling price in the ordinary course of business, less any estimated costs of completion and selling
expenses. Goods in transit as of year-end are valued based on the supplier’s invoice cost.
Tenaris establishes an allowance for obsolete or slow-moving inventories related to finished goods, goods in process,
supplies and spare parts. For slow moving or obsolete finished products, an allowance is established based on
management’s analysis of product aging. An allowance for obsolete and slow-moving inventory of supplies and spare
parts is established based on management's analysis of such items to be used as intended and the consideration of
potential obsolescence due to technological changes, aging and consumption patterns.

K Trade and other receivables
Trade and other receivables are recognized initially at fair value that corresponds to the amount of consideration that is
unconditional unless they contain significant financing components. The Company holds trade receivables with the objective
to collect the contractual cash flows and therefore measures them subsequently at amortized cost using the effective
interest method. Due to the short-term nature, their carrying amount is considered to be the same as their fair value.
Tenaris applies the IFRS 9 “Financial Instruments” simplified approach to measure expected credit losses, which uses a
lifetime expected loss allowance for all trade receivables. To measure the expected credit losses, trade receivables have
been grouped based on shared credit risk characteristics and the days past due. The expected loss rates are based on the
payment profiles of sales over a period of three years and the corresponding historical credit losses experienced within this
period. The expected loss allowance also reflects current and forward-looking information on macroeconomic factors
affecting the ability of each customer to settle the receivables.

L Cash and cash equivalents
Cash and cash equivalents are comprised of cash at banks, liquidity funds and short-term investments with a maturity of less
than three months at the date of purchase which are readily convertible to known amounts of cash. Assets recorded in cash
and cash equivalents are carried at fair market value or at historical cost which approximates fair market value.
In the Consolidated Statement of Financial Position, bank overdrafts are included in Borrowings in current liabilities.
For the purposes of the Consolidated Statement of Cash Flows, Cash and cash equivalents includes overdrafts.

M Equity
(1) Equity components
The Consolidated Statement of Changes in Equity includes:
The value of share capital, legal reserve, share premium and other distributable reserves calculated in accordance
with Luxembourg law;
The currency translation adjustment, other reserves, retained earnings and non-controlling interest calculated in
accordance with IFRS.
(2) Share capital
The Company has an authorized share capital of a single class of 2.5 billion shares having a nominal value of $1.00 per
share. Total ordinary shares issued and outstanding as of December 31, 2022, 2021 and 2020 are 1,180,536,830 with a
par value of $1.00 per share with one vote each. All issued shares are fully paid.

(3) Dividends distribution by the Company to shareholders
Dividends distributions are recorded in the Company’s financial statements when Company’s shareholders have the right
to receive the payment, or when interim dividends are approved by the Board of Directors in accordance with the by-
laws of the Company.
Dividends may be paid by the Company to the extent that it has distributable retained earnings, calculated in accordance
with Luxembourg law. See note 26 (iii) to these Consolidated Financial Statements.


N Borrowings
Borrowings are recognized initially at fair value net of transaction costs incurred and subsequently measured at amortized
cost. Any difference between the proceeds (net of transaction costs) and the redemption amount is recognized in profit
or loss over the period of the borrowings using the effective interest method.



O Current and deferred income tax
The income tax expense or credit for the period is the tax payable or recoverable on the current period’s taxable income
based on the applicable income tax rate for each jurisdiction adjusted by changes in deferred tax assets and liabilities
attributable to temporary differences and to unused tax losses. Tax is recognized in the Consolidated Income Statement,
except for tax items recognized in other comprehensive income or directly in equity.
The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the reporting
date in the countries where the Company’s subsidiaries operate and generate taxable income. Management periodically
evaluates positions taken in tax returns with respect to situations in which applicable tax regulations are subject to
interpretation and establishes provisions when appropriate.
Deferred income tax is recognized applying the liability method on temporary differences arising between the tax bases
of assets and liabilities and their carrying amounts in the financial statements. The temporary differences arise mainly
from the effect of currency translation on depreciable fixed assets and inventories, depreciation on property, plant and
equipment, valuation of inventories, provisions for post-employment benefits and other long-term employee benefits,
fair value adjustments of assets acquired in business combinations and net operating loss carry-forwards. Deferred tax
assets and liabilities are measured at the tax rates that are expected to apply in the time period when the asset is realized
or the liability is settled, based on tax laws that have been enacted or substantively enacted at the reporting date.

Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax
regulation is subject to interpretation and considers whether it is probable that a taxation authority will accept an
uncertain tax treatment. The Company measures its tax balances either based on the most likely amount or the expected
value, depending on which method provides a better prediction of the resolution of the uncertainty.
Deferred tax assets are recognized to the extent that it is probable that future taxable income will be available against
which the temporary differences can be utilized. At the end of each reporting period, Tenaris reassesses unrecognized
deferred tax assets. Tenaris recognizes a previously unrecognized deferred tax asset to the extent that it has become
probable that future taxable income will allow the deferred tax asset to be recovered.
Deferred tax liabilities and assets are not recognized for temporary differences between the carrying amount and tax
basis of investments in foreign operations where the company is able to control the timing of the reversal of the
temporary differences and it is probable that the differences will not reverse in the foreseeable future.
Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets and
liabilities and when the deferred tax balances relate to the same taxation authority. Current tax assets and tax liabilities
are offset where the entity has a legally enforceable right to offset and intends either to settle on a net basis, or to realize
the asset and settle the liability simultaneously.
Deferred tax assets and liabilities are re-measured if tax rates change. These amounts are charged or credited to the
Consolidated Income Statement or to the item Other comprehensive income in the Consolidated Statement of
Comprehensive Income, depending on the account to which the original amount was charged or credited.

P Employee benefits
(1) Short-term obligations
Liabilities for wages and salaries are recognized in respect of employees’ services up to the end of the reporting period
and are measured at the amounts expected to be paid when the liabilities are settled. The liabilities are presented as
current employee benefit obligations in the balance sheet.
(2) Post-employment benefits
The Company has defined benefit and defined contribution plans. A defined benefit plan is a pension plan that defines
an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors
such as age, years of service and compensation.
The liability recognized in the statement of financial position in respect of defined benefit pension plans is the present
value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets, if any. The
defined benefit obligation is calculated annually (at year end) by independent actuaries using the projected unit credit
method. The present value of the defined benefit obligation is determined by discounting the estimated future cash flows
using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be
paid, and that have terms to maturity approximating to the terms of the related pension obligation.
Remeasurement gains and losses arising from experience adjustments and changes in actuarial assumptions are charged
or credited to equity in Other comprehensive income in the period in which they arise. Past-service costs are recognized
immediately in the Income Statement.
For defined benefit funded plans, net interest income / expense is calculated based on the surplus or deficit derived by
the difference between the defined benefit obligations less fair value of plan assets. For defined contribution plans, the
Company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual
or voluntary basis. The Company has no further payment obligations once the contributions have been paid. The
contributions are recognized as employee benefit expenses when they are due. Prepaid contributions are recognized as
an asset to the extent that a cash refund or a reduction in the future payments is available.
Tenaris sponsors funded and unfunded defined benefit pension plans in certain subsidiaries. The most significant are:
An unfunded defined benefit employee retirement plan for certain senior officers. The plan is designed to provide
certain benefits to those officers (additional to those contemplated under applicable labor laws) in case of
termination of the employment relationship due to certain specified events, including retirement. This unfunded
plan provides defined benefits based on years of service and final average salary. As of December 31, 2022 the
outstanding liability for this plan amounts to $43.1 million.
Employees’ service rescission indemnity: the cost of this obligation is charged to the Consolidated Income Statement
over the expected service lives of employees. This provision is primarily related to the liability accrued for employees
at Tenaris’s Italian subsidiary. As from January 1, 2007 as a consequence of a change in an Italian law, employees
were entitled to make contributions to external funds, thus, Tenaris’s Italian subsidiary pays every year the required
contribution to the funds with no further obligation. As a result, the plan changed from a defined benefit plan to a
defined contribution plan effective from that date, but only limited to the contributions of 2007 onwards. As of
December 31, 2022 the outstanding liability for this plan amounts to $10.7 million.
Funded retirement benefit plan held in the U.S. for the benefit of some employees hired prior a certain date, frozen
for the purposes of credited service as well as determination of final average pay for the retirement benefit
calculation. Plan assets consist primarily of investments in equities and money market funds. Additionally, an
unfunded post-retirement health and life plan is present that offers limited medical and life insurance benefits to
the retirees, frozen to new participants. As of December 31, 2022 the outstanding liability for these plans amounts
to $7.1 million.

Funded retirement benefit plans held in Canada for salary and hourly employees hired prior to a certain date based
on years of service and, in the case of salaried employees, final average salary. Plan assets consist primarily of
investments in debt and equity instruments. Both plans were replaced for defined contribution plans. Effective June
2016 the salary plan was frozen for the purposes of credited service as well as determination of final average pay. As
of December 31, 2022 the plan was overfunded and the net assets related to this plan amounted to $10.4 million.
(3) Other long-term benefits
During 2007, Tenaris launched an employee retention and long-term incentive program (the “Program”) applicable to
certain senior officers and employees of the Company, who will be granted a number of units throughout the duration
of the Program. The value of each of these units is based on Tenaris’s shareholders’ equity (excluding non-controlling
interest). Until the end of 2017, the units were vested ratably over a period of four years and were mandatorily redeemed
by the Company ten years after grant date, with the option of an early redemption at seven years after the grant date.
Since 2018, the units are vested ratably over the same period and are mandatorily redeemed by the Company seven
years after grant date.
The beneficiaries of the Program are entitled to receive cash amounts based on: (i) the amount of dividend payments
made by Tenaris to its shareholders and (ii) the number of units held by each beneficiary to the Program. The payment
of the benefit is tied to the book value of the shares, and not to their market value. Tenaris valued this long-term incentive
program as a long-term benefit plan as classified in IAS 19, “Employee Benefits”.
As of December 31, 2022 and 2021, the outstanding liability corresponding to the Program amounts to $94.4 million and
$84.2 million, respectively. The total value of the units granted (vested and unvested) to date under the program,
considering the number of units and the book value per share as of December 31, 2022 and 2021, is $123.9 million and
$99.6 million, respectively.
(4) Termination benefits
Termination benefits are payable when employment is terminated by Tenaris before the normal retirement date, or
when an employee accepts voluntary redundancy in exchange for these benefits. Tenaris recognizes termination benefits
at the earlier of the following dates: (a) when it can no longer withdraw the offer of those benefits; and (b) when the
costs for a restructuring that is within the scope of IAS 37 involves the payment of terminations benefits. In the case of
an offer made to encourage voluntary redundancy, the termination benefits are measured based on the number of
employees expected to accept the offer.

(5) Other compensation obligations
Employee entitlements to annual leave, long-service leave, sick leave and other bonuses and compensations obligations
are accrued as earned.
Compensation to employees in the event of dismissal is charged to income in the year in which it becomes payable.

Q Provisions
Tenaris is subject to various claims, lawsuits and other legal proceedings, including customer claims, in which a third party
is seeking payment for alleged damages, reimbursement for losses or indemnity. Tenaris’s potential liability with respect
to such claims, lawsuits and other legal proceedings cannot be estimated with certainty. Management periodically
reviews the status of each significant matter and assesses potential financial exposure. If, as a result of past events, a
potential loss from a claim or proceeding is considered probable and the amount can be reliably estimated, a provision
is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be incurred based on
information available to management as of the date of preparation of the financial statements, and take into
consideration Tenaris’s litigation and settlement strategies. These estimates are primarily constructed with the assistance
of legal counsel. As the scope of liabilities become better defined, there may be changes in the estimates of future costs
which could have a material adverse effect on its results of operations, financial condition and cash flows.
If Tenaris expects to be reimbursed for an accrued expense, as would be the case for an expense or loss covered under
an insurance contract, and reimbursement is considered virtually certain, the expected reimbursement is recognized as
a receivable.

This note should be read in conjunction with note 26 to these Consolidated Financial Statements.

R Trade and other payables
Trade and other payables are recognized initially at fair value, generally the nominal invoice amount and subsequently
measured at amortized cost. They are presented as current liabilities unless payment is not due within twelve months
after the reporting period. Due to the short-term nature their carrying amounts are considered to be the same as their
fair value.


S Revenue recognition
Revenue comprises the fair value of the consideration received or receivable for the sale of goods and rendering of
services in the ordinary course of Tenaris’s activities. The revenue recognized by the Company is measured at the
transaction price of the consideration received or receivable to which the Company is entitled to, reduced by estimated
returns and other customer credits, such as discounts and volume rebates, based on the expected value to be realized
and after eliminating sales within the group.
Revenue is recognized at a point in time or over time from sales when control has been transferred and there is no
unfulfilled performance obligation that could affect the acceptance of the product by the customer. The control is
transferred upon delivery. Delivery occurs when the products have been shipped to the specific location, the risks of
obsolescence and loss have been transferred and either the customer has accepted the product in accordance with the
sales contract, the acceptance provisions have lapsed or the Company has objective evidence that all criteria for
acceptance have been satisfied, including all performance obligations. These conditions are determined and analyzed on
a contract by contract basis to ensure that all performance obligations are fulfilled. In particular, Tenaris verifies customer
acceptance of the goods, the satisfaction of delivery terms and any other applicable condition.
For bill and hold transactions revenue is recognized only to the extent that (a) the reason for the bill and hold arrangement
must be substantive (for example, the customer has requested the arrangement); (b) the products have been specifically
identified and are ready for delivery; (c) the Company does not have the ability to use the product or to direct it to another
customer; (d) the usual payment terms apply.
The Company’s contracts with customers do not provide any material variable consideration, other than discounts,
rebates and right of return. Discounts and rebates are recognized based on the most likely value and rights of return are
based on expected value considering past experience and contract conditions.

Where the contracts include multiple performance obligations, the transaction price is allocated to each performance
obligation based on the stand-alone selling prices. Where these are not directly observable, they are estimated based on
the expected cost plus margin.
There are no judgements applied by management that significantly affect the determination of timing of satisfaction of
performance obligations, nor the transaction price and amounts allocated to different performance obligations.
Tenaris provides services primarily related to goods sold, which represent a non-material portion of sales revenue and
mainly include:
Pipe Management Services: This comprises mainly preparation of the pipes ready to be run, delivery to the customer,
storage services and rig return.
Field Services: Comprises field technical support and running assistance.
These services are rendered in connection to the sales of goods and are attached to contracts with customers for the sale
of goods. A significant portion of service revenue is recognized in the same period as the goods sold. There are no distinct
uncertainties in the revenues and cash flows of the goods sold and services rendered as they are included in the same
contract, have the same counterparty and are subject to the same conditions.
The Company also provides hydraulic fracturing and coiled tubing services. The revenue related to these services is
included in the Other segment.
Revenue from providing services is recognized over time in the accounting period in which the services are rendered.
The following inputs and outputs methods are applied to recognize revenue considering the nature of service:




Graphics
Consolidated Financial Statements
For the years ended 2022, 2021 and 2020 - all amounts in thousands of U.S. dollars, unless otherwise stated
157







Storage services: the Company provides storage services in owned or third-party warehouses, subject to a variable fee to
be invoiced. This fee is determined based on the time that the customer maintains the material in the warehouse and
the amount of the material stored. In the majority of cases, to quantify the amount to be invoiced in any given month,
the monthly average fee of storage per ton is multiplied by the monthly average stock stored (in tons).
Freights: the Company recognized the revenue on a pro rata basis considering the units delivered and time elapsed.
Field services: the revenue is recognized considering output methods, in particular surveys of service completion provided
by the customer.
The Company does not expect to have any contracts where the period between the transfer of the promised goods or
services to the customer and payment by the customer exceeds one year. As a consequence, considering that the
contracts do not include any significant financing component, the Company does not adjust any of the transaction prices
for the time value of money. For this reason, the Company is also applying the practical expedient not to disclose details
on transaction prices allocated to the remaining performance obligations as of the end of the reporting period.
Tenaris only provides standard quality warranties assuring that the goods sold will function as expected or are fit for their
intended purpose, with no incremental service to the customer. Accordingly, warranties do not constitute a separate
performance obligation.
Other revenues earned by Tenaris are recognized on the following basis:
Interest income: on the effective yield basis.
Dividend income from investments in other companies: when Tenaris’s right to receive payment is established.

Construction contracts revenues are recognized in accordance with the stage of the project completion.

T Cost of sales and other selling expenses
Cost of sales and other selling expenses are recognized in the Consolidated Income Statement on the accrual basis of
accounting.
Commissions, freights and other selling expenses, including shipping and handling costs, are recorded in Selling, general
and administrative expenses in the Consolidated Income Statement.


U Earnings per share
Earnings per share are calculated by dividing the income attributable to the shareholders’ equity by the daily weighted
average number of common shares outstanding during the year.
There are no dilutive potential ordinary shares.




V Financial instruments
Non derivative financial instruments comprise investments in financial debt instruments and equity, time deposits, trade
and other receivables, cash and cash equivalents, borrowings and trade and other payables.
The Company classifies its financial instruments according to the following measurement categories:
those to be measured subsequently at fair value (either through OCI or through profit or loss), and
those to be measured at amortised cost.
The classification depends on the Company’s business model for managing the financial assets and contractual terms of
the cash flows.
Financial assets are recognized on their settlement date. Financial assets are derecognized when the rights to receive
cash flows from the financial assets have expired or have been transferred and the Company has transferred substantially
all the risks and rewards of ownership.

At initial recognition, the Company measures a financial asset at its fair value plus, in the case of a financial asset not at
fair value through profit or loss, transaction costs that are directly attributable to the acquisition of the financial asset.
Transaction costs of financial assets carried at fair value through profit or loss are expenses in profit or loss.

For the years ended 2022, 2021 and 2020 - all amounts in thousands of U.S. dollars, unless otherwise stated
158







Subsequent measurement of debt instruments depends on the Company’s business model for managing the asset and
the cash flow characteristics of the asset. There are three measurement categories into which the Company classifies its
debt instruments:
Amortized Cost: Assets that are held for collection of contractual cash flows where those cash flows represent solely
payments of principal and interest. Interest income from these financial assets is included in finance income using the
effective interest rate method.
Exchange gains and losses and impairments related to the financial assets are immediately recognized in the Consolidated
Income Statement.

Fair value through other comprehensive income: Assets that are held for collection of contractual cash flows and for
selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest. Interest
income from these financial assets is included in finance income using the effective interest rate method. Unrealized
gains or losses are recorded as a fair value adjustment in the Consolidated Statement of Comprehensive Income and
transferred to the Consolidated Income Statement when the financial asset is sold.
Fair value through profit and loss: Assets that do not meet the criteria for amortized cost or FVOCI. Changes in fair value
of financial instruments at FVPL are immediately recognized in the Consolidated Income Statement.

Equity instruments are subsequently measured at fair value.

Accounting for derivative financial instruments and hedging activities is included within the section III, Financial Risk
Management.

III. FINANCIAL RISK MANAGEMENT
The multinational nature of Tenaris’s operations and customer base exposes the Company to a variety of risks, mainly
related to market risks (including the effects of changes in foreign currency exchange rates and interest rates), credit risk
and capital market risk. In order to manage the volatility related to these exposures, management evaluates exposures
on a consolidated basis, taking advantage of exposure netting. The Company or its subsidiaries may then enter into
various derivative transactions in order to prevent potential adverse impacts on Tenaris’s financial performance. Such
derivative transactions are executed in accordance with internal policies and hedging practices.
A. Financial risk factors
(i) Capital Risk Management
Tenaris seeks to maintain a low debt to total equity ratio considering the industry and the markets where it operates.
The year-end ratio of debt to total equity (where “debt” comprises financial borrowings and “total equity” is the sum of
financial borrowings and equity) is 0.05 as of December 31, 2022 and 0.03 as of December 31, 2021. The Company does
not have to comply with regulatory capital adequacy requirements.

(ii) Foreign exchange risk
Tenaris manufactures and sells its products in a number of countries throughout the world and consequently is exposed
to foreign exchange rate risk. Since the Company’s functional currency is the U.S. dollar the purpose of Tenaris’s foreign
currency hedging program is mainly to reduce the risk caused by changes in the exchange rates of other currencies against
the U.S. dollar.
Tenaris’s exposure to currency fluctuations is reviewed on a periodic and consolidated basis. A number of derivative
transactions are performed in order to achieve an efficient coverage in the absence of operative or natural hedges.
Almost all of these transactions are forward exchange rates contracts. See note 25 to these Consolidated Financial
Statements.
Tenaris does not enter into derivative financial instruments for trading or other speculative purposes, other than non-
material investments in structured products.
In the case of subsidiaries with functional currencies other than the U.S. dollar, the results of hedging activities, reported
in accordance with IFRS, may not reflect entirely the management’s assessment of its foreign exchange risk hedging
program. Intercompany balances between Tenaris’s subsidiaries may generate financial gains (losses) to the extent that
functional currencies differ.
The value of Tenaris’s financial assets and liabilities is subject to changes arising from the variation of foreign currency
exchange rates. The following table provides a breakdown of Tenaris’s main financial assets and liabilities (including
foreign exchange derivative contracts) which impact the Company’s profit and loss as of December 31, 2022 and 2021.
All amounts Long / (Short) in thousands of U.S. dollars

As of December 31, 2022 and 2021 consisting primarily of Argentine Peso-denominated financial, trade, social and
fiscal payables at certain Argentine subsidiaries whose functional currency is the U.S. dollar. A change of 1% in the
ARS/USD exchange rate would have generated a pre-tax gain / loss of $1.3 million and $1 million as of December 31,
2022 and 2021 respectively.

Euro / U.S. dollar
As of December 31, 2022 consisting primarily of Euro-denominated intercompany liabilities at certain subsidiaries
whose functional currency is the U.S. dollar and 2021, consisting primarily of U.S. dollar-denominated intercompany
liabilities at certain subsidiaries whose functional currency is the Euro. A change of 1% in the EUR/USD exchange rate
would have generated a pre-tax gain / loss of $0.4 million and $0.1 million as of December 31, 2022 and 2021,
respectively, which would have been to a large extent offset by changes in currency translation adjustment included
in Tenaris’s net equity position.
Saudi Arabian Riyal / U. S. dollar
As of December 31, 2022 and 2021 consisting primarily of Saudi Arabian Riyal-denominated financial and trade
payables. The Saudi Arabian Riyal is tied to the U.S. dollar.
U.S. dollar / Brazilian Real
As of December 31, 2022 and 2021, consisting primarily of U.S. dollar-denominated intercompany liabilities at certain
subsidiaries whose functional currency is the Brazilian Real. A change of 1% in the BRL/USD exchange rate would
have generated a pre-tax gain / loss of $0.9 million and $0.3 million as of December 31, 2022 and 2021, respectively,
which would have been to a large extent offset by changes in currency translation adjustment included in Tenaris’s
net equity position.
Considering the balances held as of December 31, 2022 on financial assets and liabilities exposed to foreign exchange
rate fluctuations, Tenaris estimates that the impact of a simultaneous 1% appreciation / depreciation movement in the
levels of foreign currencies exchange rates relative to the U.S. dollar, would be a pre-tax gain / loss of $4 million (including
a loss / gain of $0.2 million due to foreign exchange derivative contracts), which would be partially offset by changes to
Tenaris’s net equity position of $0.9 million. For balances held as of December 31, 2021, a simultaneous 1% favorable /
unfavorable movement in the foreign currencies exchange rates relative to the U.S. dollar, would have generated a pre-
tax gain / loss of $3.1 million (including a loss / gain of $0.5 million due to foreign exchange derivative contracts), which
would have been partially offset by changes to Tenaris’s net equity position of $0.2 million.

(iii) Interest rate risk
Tenaris is subject to interest rate risk on its investment portfolio and its debt. The Company uses a mix of variable and
fixed rate debt in combination with its investment portfolio strategy. The Company may choose to enter into foreign
exchange derivative contracts and / or interest rate swaps to mitigate the exposure to changes in the interest rates.
The following table summarizes the proportions of variable-rate and fixed-rate debt as of each year end.
As of December 31,

Out of the $497.9 million fixed rate borrowings, $479 million are short-term.
The Company estimates that, if market interest rates applicable to Tenaris’s borrowings had been 100 basis points
higher, then the additional pre-tax loss would have been $5.3 million in 2022 and $5.2 million in 2021.
(iv) Credit risk
Credit risk arises from cash and cash equivalents, deposits with banks and financial institutions, as well as credit exposures
to customers, including outstanding receivables and committed transactions. The Company also actively monitors the
creditworthiness of its treasury, derivative and insurance counterparties in order to minimize its credit risk.
There is no significant concentration of credit risk from customers. No single customer comprised more than 10% of
Tenaris’s net sales in 2022, 2021 and 2020.

Tenaris’s credit policies related to sales of products and services are designed to identify customers with acceptable credit
history and to allow Tenaris to require the use of credit insurance, letters of credit and other instruments designed to
minimize credit risks whenever deemed necessary. Tenaris maintains allowances for impairment for potential credit
losses. See section II.K.
As of December 31, 2022 and 2021 trade receivables amounted to $2,493.9 million and $1,299.1 million respectively.
Trade receivables have guarantees under credit insurance of $231.2 million and $175.8 million, letter of credit and other
bank guarantees of $34.7 million and $17.8 million as of December 31, 2022 and 2021 respectively, and other guarantees
of $2.2 million as of December 31, 2021.
As of December 31, 2022 and 2021, overdue trade receivables amounted to $544.9 million and $209.6 million,
respectively. As of December 31, 2022 and 2021, overdue guaranteed trade receivables amounted to $28.1 million and
$10.6 million; and the allowance for doubtful accounts amounted to $45.5 million and $47.1 million respectively. Both
the allowance for doubtful accounts and the existing guarantees are sufficient to cover doubtful trade receivables.

(v) Counterparty risk
Tenaris has investment guidelines with specific parameters to limit issuer risk on marketable securities. Counterparties
for derivatives and cash transactions are limited to high credit quality financial institutions, normally investment grade.
Approximately 80% of Tenaris’s liquid financial assets corresponded to Investment Grade-rated instruments as of
December 31, 2022, in comparison with approximately 77% as of December 31, 2021.
(vi) Liquidity risk
Tenaris financing strategy aims to maintain adequate financial resources and access to additional liquidity. During 2022,
Tenaris has counted on cash flows from operations as well as additional bank financing to fund its transactions.
Management maintains sufficient cash and marketable securities to finance normal operations and believes that Tenaris
also has appropriate access to market for short-term working capital needs.
Liquid financial assets as a whole (comprising cash and cash equivalents and other investments) were 9% and 7% of total
assets at the end of 2022 and 2021, respectively.
Tenaris has a conservative approach to the management of its liquidity, which consists of i) cash and cash equivalents
(cash in banks, liquidity funds and investments with a maturity of less than three months at the date of purchase), and ii)
other investments (fixed income securities, time deposits, and fund investments).
Tenaris holds primarily investments in money market funds and variable or fixed-rate securities from investment grade
issuers. As of December 31, 2022 and 2021 Tenaris held $5 million and $6 million in direct exposure to financial
instruments issued by European sovereign counterparties respectively.
Tenaris holds its investments primarily in U.S. dollars. As of December 31, 2022 and 2021, U.S. dollar denominated liquid
assets plus investments denominated in other currencies hedged to the U.S. dollar represented approximately 87% of
total liquid financial assets.

(vii) Commodity price risk
In the ordinary course of its operations, Tenaris purchases commodities and raw materials that are subject to price
volatility caused by supply conditions, political and economic variables and other factors. As a consequence, Tenaris is
exposed to risk resulting from fluctuations in the prices of these commodities and raw materials. Tenaris fixes the prices
of such raw materials and commodities for short-term periods, typically not in excess of one year, and in general hedging
for these risks is performed on a limited basis.

B. Category of financial instruments and classification within the fair value hierarchy
As mentioned in note II.A, the Company classifies its financial instruments in the following measurement categories:
amortized cost, fair value through other comprehensive income and fair value through profit and loss. For financial
instruments that are measured in the statement of financial position at fair value, IFRS 13, Fair value measurement”
requires a disclosure of fair value measurements by level according to the following fair value measurement hierarchy:
Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities.
Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either
directly (that is, as prices) or indirectly (that is, derived from prices).
Level 3 - Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs).
The following tables present the financial instruments by category and levels as of December 31, 2022 and 2021.

There were no transfers between levels during the year.

The fair value of financial instruments traded in active markets is based on quoted market prices at the reporting date. A
market is regarded as active if quoted prices are readily and regularly available from an exchange, dealer, broker, industry
group, pricing service, or regulatory agency, and those prices represent actual and regularly occurring market transactions
on an arm’s length basis. The quoted market price used for financial assets held by Tenaris is the current bid price. These
instruments are included in Level 1 and comprise primarily corporate and sovereign debt securities.
The fair value of financial instruments that are not traded in an active market (such as certain debt securities, certificates
of deposits with original maturity of more than three months, forward and interest rate derivative instruments) is
determined by using valuation techniques which maximize the use of observable market data when available and rely as
little as possible on entity specific estimates. If all significant inputs required to value an instrument are observable, the
instrument is included in Level 2. Tenaris values its assets and liabilities included in this level using bid prices, interest rate
curves, broker quotations, current exchange rates, forward rates and implied volatilities obtained from market
contributors as of the valuation date.
If one or more of the significant inputs are not based on observable market data, the instruments are included in Level
3. Tenaris values its assets and liabilities in this level using observable market inputs and management assumptions which
reflect the Company’s best estimate on how market participants would price the asset or liability at measurement date.
Main balances in this level include net receivables related to the Company interest in the Venezuelan Companies for a
total amount of approximately $48.7 million, which reflects the best estimation of the fair value calculated using the
probability of occurrence of weighted scenarios applied to the potential transaction value resulting from the awards
purchase agreement mentioned in note 34 to these Consolidated Financial Statements.

C. Fair value estimation
Financial assets or liabilities classified at fair value through profit or loss are measured under the framework established
by the IASB accounting guidance for fair value measurements and disclosures.

The fair values of quoted investments are generally based on current bid prices. If the market for a financial asset is not
active or no market is available, fair values are established using standard valuation techniques.
The fair value of all outstanding derivatives is determined using specific pricing models that include inputs that are
observable in the market or can be derived from or corroborated by observable data. The fair value of forward foreign
exchange contracts is calculated as the net present value of the estimated future cash flows in each currency, based on
observable yield curves, converted into U.S. dollars at the spot rate of the valuation date.
Borrowings are classified under other financial liabilities and measured at their amortized cost. Tenaris estimates that
the fair value of its main financial liabilities is approximately 99.2% and 99.6% of its carrying amount (including interests
accrued) in 2022 and 2021 respectively. Fair values were calculated using standard valuation techniques for floating rate
instruments and comparable market rates for discounting cash flows.

The carrying amount of investments valuated at amortized cost approximates its fair value.



D. Accounting for derivative financial instruments and hedging activities
Derivative financial instruments are initially recognized in the statement of financial position at fair value through profit
and loss on each date a derivative contract is entered into and are subsequently remeasured at fair value. Specific tools
are used for calculation of each instrument’s fair value and these tools are tested for consistency on a monthly basis.
Market rates are used for all pricing operations. These include exchange rates, deposit rates and other discount rates
matching the nature of each underlying risk.
As a general rule, Tenaris recognizes the full amount related to the change in fair value of derivative financial instruments
in Financial Results in the Consolidated Income Statement.
Tenaris designates certain derivatives as hedges of particular risks associated with recognized assets or liabilities or highly
probable forecast transactions. These transactions are classified as cash flow hedges. The effective portion of the fair
value of derivatives that are designated and qualify as cash flow hedges is recognized in equity. Amounts accumulated in
equity are then recognized in the income statement in the same period as the offsetting losses and gains on the hedged
item. The gain or loss relating to the ineffective portion is recognized immediately in the income statement. The fair value
of Tenaris’s derivative financial instruments (assets or liabilities) continues to be reflected in the statement of financial
position.
For transactions designated and qualifying for hedge accounting, Tenaris documents at the inception of the transaction
the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy
for undertaking various hedge transactions. Tenaris also documents its assessment on an ongoing basis, of whether the
hedging instruments are highly effective in offsetting changes in the fair value or cash flow of hedged items. At December
31, 2022 and 2021, the effective portion of designated cash flow hedges which is included in Other Reserves in equity
amounted to $13.1 million credit and $1.3 million credit respectively.
The fair values of various derivative instruments used for hedging purposes and the movements of the hedging reserve
included within Other Reserves in equity are disclosed in note 25 to these Consolidated Financial Statements.

Transactions between segments, which were eliminated in consolidation, are mainly related to sales of scrap, energy,
surplus raw materials and others from the Other segment to the Tubes segment for $77.9 million, $45.6 million and $16.9
million in 2022, 2021 and 2020, respectively.
There are no material differences between IFRS and management view in total revenues and by reportable segments.
The differences between operating income under IFRS view and the management view are mainly related to the cost of
goods sold, reflecting the effect of raw materials prices increases on the valuation of the replacement cost considered
for management view compared to IFRS cost calculated at historical cost on a FIFO basis, and other minor timing
differences.

The main difference in Other operating income (expenses), for the year ended December 31, 2022, is attributable to the
effect of the reclassification of the currency translation adjustment reserve related to NKK Tubes’ definitive cease of
operations, not impacting the management view. For the year ended in December 31, 2020, the main difference in Other
operating income (expenses) is attributable to the impairment of the goodwill, which residual value in the management
view differed from IFRS.
In addition to the amounts reconciled above, the main differences in net income arise from the impact of functional
currencies on financial result, deferred income taxes as well as the result of investment in non-consolidated companies.

5 Impairment charge
Tenaris’s main source of revenue is the sale of products and services to the oil and gas industry, and the level of such
sales is sensitive to international oil and gas prices and their impact on drilling activities.
The Company conducts regular assessments of the carrying values of its assets. The recoverable value is based on the
value in use. The main key assumptions used in estimating the value in use are discount rate, growth rate and competitive,
economic and regulatory factors applied to determine cash flow projections, such as oil and gas prices, average number
of active oil and gas drilling rigs (rig count) and raw material costs. In December 2022, the Company conducted
impairment tests, and also reviewed and impaired the values of certain idle assets in its subsidiaries.
For purposes of assessing key assumptions, to estimate discounted future cash flows, the Company uses external sources
of information and management judgment based on past experience and expectations. Management has determined
the value of each of the key assumptions as follows:
- Discount rate: based on the applicable weighted average cost of capital (“WACC”), which is considered to be a good
indicator of capital cost, taking into account the industry, country and size of the business. For each CGU where assets
are allocated, a specific WACC was determined. In 2022, the main discount rates used were in a range between 13.4%
and 20.2%.
- Growth rate: considers mainly the inflation impact on prices and costs, the long-term evolution of the oil and gas
industry, the higher demand to offset depletion of existing fields and the Company’s expected market penetration. In
2022, a nominal growth rate of 2% was considered.
- Oil and gas prices: based on industry analysts’ reports and management’s expectations of market development.
- Rig count: based on information published by Baker Hughes and management’s expectations.
- Raw material costs: based on industry analysts’ reports and management’s expectations.
In December 2022, in the presence of impairment indicators, the Company conducted impairment tests and reviewed
the values of certain idle assets in its subsidiaries. The aforementioned analysis resulted in impairment charges of $76.7
million, allocated in $63.1 million to the Tubes segment and $13.6 million to the Other segment.
In December, 2021, as a result of the expected termination of the NKKTubes joint venture, which represented an
impairment indicator for its assets, an impairment test was conducted, resulting in a charge of $57 million that totally
reduced the carrying amounts of property, plant and equipment and intangible assets. The total amount was allocated
to the Tubes segment. Remaining carrying amounts after the recognition of impairment charges amounted to $53 million
mainly related to working capital.
For the year 2020 a charge of approximately $622 million, impacting the carrying value of goodwill of the CGUs OCTG-
USA, IPSCO and Coiled Tubing for $225 million, $357 million and $4 million respectively, and the carrying value of
property, plant and equipment of the CGU Rods-USA for $36 million was recorded. Out of the total amount, $582 million
were allocated to the Tubes segment.

On May 13, 2021, the Brazilian Supreme Court issued a final judgment which confirmed that the methodology for calculating PIS and COFINS (Federal
Social Contributions on Gross Revenues) tax claims to which taxpayers are entitled to, should exclude from its base the total output of ICMS, calculated
on a gross basis. This decision led to a recognition of approximately $53 million tax credit in Brazilian subsidiaries, out of which $36 million were
recognized in other operating income and $17 million in financial results (impacting in Finance Income and Finance Cost). In addition the tax charge
related to this gain amounted to $12 million.

Effect of currency translation on tax base, Tenaris applies the liability method to recognize deferred income tax on
temporary differences between the tax bases of assets / liabilities and their carrying amounts in the financial statements.
By application of this method, Tenaris recognizes gains and losses on deferred income tax due to the effect of the change
in the value on the tax bases in subsidiaries (mainly Argentina and Mexico), which have a functional currency different
than their local currency. These gains and losses are required by IFRS even though the revalued / devalued tax bases of
the relevant assets will not result in any deduction / obligation for tax purposes in future periods.
Changes in the tax rates includes mainly the effect of the increase in the corporate income tax rate in Argentina from
25% to 35% for fiscal years starting January 1, 2021.
Tax revaluation, withholding tax and others, includes a net tax income of $250 million, $113 million and $61 million for
2022, 2021 and 2020 respectively related to the tax revaluation regimes in Argentina and Mexico. It also includes a charge
of $21 million, $23 million and $10 million for 2022, 2021 and 2020 respectively related to withholding taxes for intra-
group international operations.

At December 31, 2022, the closing price of Ternium’s ADSs as quoted on the New York Stock Exchange was $30.56 per
ADS, giving Tenaris’s ownership stake a market value of approximately $702 million. At December 31, 2022, the carrying
value of Tenaris’s ownership stake in Ternium, based on Ternium’s IFRS Financial Statements, was approximately $1,363.6
million. The Company reviews its participation in Ternium whenever events or circumstances indicate that the asset’s
carrying amount may not be recoverable. As of December 31, 2022, the Company concluded that the carrying amount
does not exceed the recoverable value of the investment.

b) Usiminas
Usiminas is a Brazilian producer of high quality flat steel products used in the energy, automotive and other industries.
As of December 31, 2022, the closing price of the Usiminas’ ordinary and preferred shares, as quoted on the B3 - Brasil
Bolsa Balcão S.A, was BRL7.41 ($1.42) and BRL7.16 ($1.37), respectively, giving Tenaris’s ownership stake a market value
of approximately $53.6 million. As of that date, the carrying value of Tenaris’s ownership stake in Usiminas was
approximately $109.5 million.
For the year ended December 31, 2022, the Company conducted an impairment test and - mainly due to the lower
expectations of steel demand and market steel prices, together with a worsened global macroeconomic situation that
derived in the increase in discount rates - wrote down its investment in Usiminas by $19.1 million. The value-in-use was
used to determine the recoverable value. Value-in-use was calculated discounting the estimated cash flows over a five-
year period based on forecasts approved by management. For the subsequent years beyond the five-year period, a
terminal value was calculated based on perpetuity considering a nominal growth rate of 2%. The discount rate used for
such test was 13.5% and is based on the respective WACC, which is considered to be a good indicator of capital cost. The
main factors that could result in additional impairment charges in future periods would be an increase of the discount
rate, or a deterioration of the macroeconomic situation, steel demand and prices. Management has considered and
assessed reasonably possible changes in the key assumptions and has not identified any instances that could give rise to
an additional material impairment charge over its investment in Usiminas.
Summarized selected financial information of Usiminas, including the aggregated amounts of assets, liabilities, revenues
and profit or loss is as follows:

c) Techgen
Techgen is a Mexican company that operates a natural gas-fired combined cycle electric power plant in the Pesquería
area of the State of Nuevo León, Mexico, with a power capacity of 900 megawatts. As of December 31, 2022, Tenaris held
22% of Techgen’s share capital, and its affiliates, Ternium and Tecpetrol (both controlled by San Faustin), held 48% and
30% respectively. As of December 31, 2022, the carrying value of Tenaris’s ownership stake in Techgen was approximately
$41.5 million.
Techgen entered into certain transportation capacity agreements, equipment and other services related to the
equipment, and an agreement for the purchase of clean energy certificates. As of December 31, 2022, Tenaris’s exposure
under these agreements amounted to $42.5 million, $0.9 million and $17.2 million respectively.
Techgen’s sponsors granted certain subordinated loans to Techgen. As of December 31, 2022, the aggregate outstanding
principal amount under these subordinated loans was $264.2 million, of which $58.1 million correspond to Tenaris’s
contribution.
On February 13, 2019, Techgen entered into a $640 million syndicated loan agreement with several banks to refinance
an existing loan, resulting in the release of certain corporate guarantees previously issued by Techgen’s shareholders to
secure the replaced facility.

The existing syndicated loan agreement is non-recourse” on the sponsors. Techgen’s obligations thereunder are
guaranteed by a Mexican security trust (covering shares, assets, accounts and contract rights), account pledges and
certain direct agreements customary for these type of transactions. The commercial terms and conditions governing
the purchase by the Company’s Mexican subsidiary, Tamsa, of 22% of the energy generated by Techgen remain
substantially unchanged.
Under the loan agreement, Techgen is committed to maintain a debt service reserve account covering debt service
becoming due during two consecutive quarters; such account is funded by stand-by letters of credit issued for the account
of Techgen’s sponsors in proportion to their respective participations in Techgen. Accordingly, the Company applied for
stand-by letters of credit covering 22% of the debt service coverage ratio, which as of December 31, 2022, amounted to
$10.3 million.
d) GPC
GPC is a Saudi-German joint venture, established in 2010 and located in Jubail, Saudi Arabia, which manufactures LSAW
pipes. Tenaris, through its subsidiary SSPC, currently owns 35% of the share capital of GPC. As of December 31, 2022, the
carrying value of Tenaris’s ownership stake in GPC was approximately $23 million.
SSPC and the other three owners of GPC have issued corporate guarantees to secure repayment of loan agreements
entered into by GPC, with the Saudi Investment Development Fund, the Saudi British Bank, the National Commercial Bank
and Banque Saudi Fransi to finance GPC’s capital expenditures and working capital. As of December 31, 2022, SSPC’s
exposure under the guarantees amounted to $84 million.
In December 2022, EEW, a German company that owns another 35% interest in GPC, expressed its intention to sell its
entire interest in GPC for a cash amount of $9.9 million and a release of EEW’s corporate guarantees with respect to
GPC’s debt. SSPC and another shareholder that owns a 20% interest in GPC exercised their respective rights of first refusal.
Each such acquisition is subject to customary conditions, including competition clearance and bank consents. If both
acquisitions are consummated, SSPC will acquire a 22.3% additional interest in GPC (thus totaling a 57.3% interest) and
will assume a portion of EEW’s corporate guarantees (so that SSPC’s exposure under the guarantees will increase to
$137.5 million based on debt amounts as of December 31, 2022).

Deferred tax assets related to taxable losses of Tenaris subsidiaries are recognized to the extent it is considered probable
that future taxable profits will be available, against which such losses can be utilized in the foreseeable future. This
amount includes $300 million related to U.S. subsidiaries mainly due to the recognition of accelerated fiscal depreciations,
as well as the amounts related to the acquisition of IPSCO in 2020. The remaining balance mainly corresponds to Tenaris’s
Saudi Arabian subsidiaries. These subsidiaries have incurred in fiscal losses in the past one or two years. Tenaris has
concluded that these deferred tax assets will be recoverable based on the business plans and budgets.
Approximately 100% of the recognized tax losses have an expiration date in more than 5 years or do not expire.
As of December 31, 2022, the net unrecognized deferred tax assets amounted to $120.4 million. Unrecognized tax credits
with expiration dates in less than 1 year, between 2 and 5 years and more than 5 years or without expiration date are
approximately 8%, 4% and 88% respectively.
The estimated recovery analysis of deferred tax assets and settlement of deferred tax liabilities, which takes into
consideration management assumptions and estimates, is as follows:
Year ended December 31,
2022
2021
Deferred tax assets to be recovered after 12 months
(171,717)
(611,552)
Deferred tax liabilities to be settled after 12 months
688,124

Deferred income tax assets and liabilities are offset when (1) there is a legally enforceable right to set-off current tax
assets against current tax liabilities and (2) when the deferred income taxes relate to the same fiscal authority on either
the same taxable entity or different taxable entities where there is an intention to settle the balances on a net basis. The
following amounts, determined after appropriate set-off, are shown in the Consolidated Statement of Financial Position:

For 2022 a gain of $0.1 million is attributable to demographic assumptions and a gain of $4.1 million to financial assumptions.
For 2021 a loss of $0.7 million is attributable to demographic assumptions and a loss of $2.5 million to financial assumptions.
The actuarial assumptions for the most relevant plans were as follows:
Year ended December 31,
2022
2021
Discount rate
4% - 7%
1% - 7%
Rate of compensation increase
2% - 3%
0% - 3%
As of December 31, 2022, an increase / (decrease) of 1% in the discount rate assumption of the main plans would have
generated a (decrease) / increase on the defined benefit obligation of $5.2 million and $5.9 million respectively, and an
increase / (decrease) of 1% in the rate of compensation assumption of the main plans would have generated an increase
/ (decrease) impact on the defined benefit obligation of $3.2 million and $2.9 million respectively. The above sensitivity
analyses are based on a change in discount rate and rate of compensation while holding all other assumptions constant.
In practice, this is unlikely to occur, and changes in some of the assumptions may be correlated.

Discount rate
3% - 5%
2% - 3%
Rate of compensation increase
0% - 3%

The expected return on plan assets is determined by considering the expected returns available on the assets underlying
the current investment policy. Expected return on plan assets is determined based on long-term, prospective rates of
return as of the end of the reporting period.
As of December 31, 2022, an increase / (decrease) of 1% in the discount rate assumption of the main plans would have
generated a (decrease) / increase on the defined benefit obligation of $10.3 million and $11.9 million respectively, and
an increase / (decrease) of 1% in the compensation rate assumption of the main plans would have generated an increase
/ (decrease) on the defined benefit obligation of $0.7 million and $0.7 million respectively. The above sensitivity analyses
are based on a change in discount rate and rate of compensation while holding all other assumptions constant. In practice,
this is unlikely to occur, and changes in some of the assumptions may be correlated.
There are no expected employer contributions for the year 2023.
The methods and types of assumptions used in preparing the sensitivity analyses did not change compared to the
previous period.

Tenaris estimates that the cash flow hedge reserve corresponding to derivatives instruments at December 31, 2022 will be
recycled to the Consolidated Income Statement during 2023. For information on hedge accounting reserve, see section III.D
to these Consolidated Financial Statements.


26 Contingencies, commitments and restrictions on the distribution of profits
(i) Contingencies
Tenaris is from time to time subject to various claims, lawsuits and other legal proceedings, including customer,
employee, tax and environmental-related claims, in which third parties are seeking payment for alleged damages,
reimbursement for losses, or indemnity. Management with the assistance of legal counsel periodically reviews the status
of each significant matter and assesses potential financial exposure.
Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are
subject to substantial uncertainties and, therefore, the probability of loss and an estimation of damages are difficult to
ascertain. Accordingly, with respect to a large portion of such claims, lawsuits and other legal proceedings, the Company
is unable to make a reliable estimate of the expected financial effect that will result from ultimate resolution of the
proceeding. In those cases, the Company has not accrued a provision for the potential outcome of these cases.
If a potential loss from a claim, lawsuit or other proceeding is considered probable and the amount can be reasonably
estimated, a provision is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be
incurred based on information available to management as of the date of preparation of the financial statements and
take into consideration litigation and settlement strategies. In a limited number of ongoing cases, the Company was able
to make a reliable estimate of the expected loss or range of probable loss and, depending on the likelihood of occurrence,
in some of such cases has accrued a provision for such loss but believes that publication of this information on a case-by-
case basis would seriously prejudice the Tenaris’s position in the ongoing legal proceedings or in any related settlement
discussions. Accordingly, in these cases, the Company has disclosed information with respect to the nature of the
contingency but has not disclosed its estimate of the range of potential loss.
The Company believes that the aggregate provisions recorded for potential losses in these Consolidated Financial
Statements are adequate based upon currently available information. However, if management’s estimates prove
incorrect, current reserves could be inadequate and the Company could incur a charge to earnings which could have a
material adverse effect on its results of operations, financial condition, net worth and cash flows.
Below is a summary description of Tenaris’s material legal proceedings which are outstanding as of the date of these
Consolidated Financial Statements. In addition, the Company is subject to other legal proceedings, none of which is
believed to be material.
CSN claims relating to the January 2012 acquisition of Usiminas
Confab, a Brazilian subsidiary of the Company, is one of the defendants in a lawsuit filed in Brazil by Companhia
Siderúrgica Nacional (“CSN”) and various entities affiliated with CSN against Confab and several Ternium subsidiaries that
acquired a participation in Usiminas’ control group in January 2012.
The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along
tender offer to all non-controlling holders of Usiminas’ ordinary shares for a price per share equal to 80% of the price per
share paid in such acquisition, or BRL28.8, and seeks an order to compel the acquirers to launch an offer at that price
plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging
to Usiminas’ control group, and Confab would have a 17.9% share in that offer.

On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals
maintained the understanding of the first instance court. On August 18, 2017, CSN filed an appeal to the Superior Court
of Justice seeking the review and reversal of the decision issued by the Court of Appeals. On March 5, 2018, the court of
appeals ruled that CSN’s appeal did not meet the requirements for submission to the Superior Court of Justice and
rejected the appeal. On May 8, 2018, CSN appealed against such ruling and on January 22, 2019, the court of appeals
rejected it and ordered that the case be submitted to the Superior Court of Justice. On September 10, 2019, the Superior
Court of Justice declared CSN’s appeal admissible. On March 7, 2023, the Superior Court of Justice, by majority vote,
rejected CSN’s appeal. Plaintiffs may still appeal against the Superior Court of Justice’s decision. At this time, the Company
cannot predict whether CSN will appeal against the decision and, if appealed, the ultimate resolution of the matter.
The Company continues to believe that all of CSN’s claims and allegations are groundless and without merit, as confirmed
by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator (“CVM”) in
February 2012 and December 2016, the first and second instance court decisions and the March 2023 decision of the
Superior Court of Justice referred to above.
Veracel celulose accident litigation
On September 21, 2007, an accident occurred in the premises of Veracel Celulose S.A. (“Veracel”) in connection with a
rupture in one of the tanks used in an evaporation system manufactured by Confab. The Veracel accident allegedly
resulted in material damages to Veracel. Itaú Seguros S.A. (“Itaú”), Veracel’s insurer at the time of the Veracel accident
and then replaced by Chubb Seguros Brasil S/A (“Chubb”), initiated a lawsuit against Confab seeking reimbursement of
damages paid to Veracel in connection with the Veracel accident. Veracel initiated a second lawsuit against Confab
seeking reimbursement of the amount paid as insurance deductible with respect to the Veracel accident and other
amounts not covered by insurance. Itaú and Veracel claimed that the Veracel accident was caused by failures and defects
attributable to the evaporation system manufactured by Confab. Confab believes that the Veracel accident was caused
by the improper handling by Veracel’s personnel of the equipment supplied by Confab in violation of Confab’s
instructions. The two lawsuits were consolidated and are considered by the 6th Civil Court of São Caetano do Sul.
However, each lawsuit will be adjudicated separately.
On September 28, 2018, Confab and Chubb entered into a settlement agreement pursuant to which on October 9, 2018,
Confab paid an amount of approximately $3.5 million to Chubb, without assuming any liability for the accident or the
claim.
On October 10, 2018, Confab was notified that the court had issued rulings for both lawsuits. Both decisions were
unfavorable to Confab:
With respect to Chubb’s claim, the court subsequently homologated the above-mentioned settlement and,
accordingly, the claim was finalized.
With respect to Veracel’s claim, Confab was ordered to pay the insurance deductible and other concepts not
covered by insurance, currently estimated to amount to BRL91.9 million (approximately $17.4 million) including
interest, fees and expenses. Both parties filed motions for clarification against the court’s decision, which were
partially granted. Although the contract between Confab and Veracel expressly provided that Confab would not
be liable for damages arising from lost profits, the court award would appear to include BRL78.8 million
(approximately $15.10 million) of damages arising therefrom. Confab has additional defense arguments in respect
of a claim for lost profits. On December 18, 2018, Confab filed an appeal against the first instance court decision,
and on April 30, 2019, Veracel filed its response to the appeal. In June 2022, the court resolved that it lacked
jurisdiction to decide on the appeal, which was re-allocated to another court. The parties are currently waiting
for the trial of the appeal to be scheduled. At this stage the Company cannot predict the outcome of the claim or
the amount or range of loss in case of an unfavorable outcome.

Petrobras-related proceedings and claims
The Company is aware that Brazilian, Italian and Swiss authorities investigated whether certain payments were made
prior to 2014 from accounts of entities presumably associated with affiliates of the Company to accounts allegedly linked
to individuals related to Petróleo Brasileiro S.A. (“Petrobras”) and whether any such payments were intended to benefit
the Company’s Brazilian subsidiary Confab.
Upon learning of the investigation, the Audit Committee of the Company's Board of Directors engaged external counsel
in connection with the Company’s review of these matters. In addition, the Company voluntarily notified the U.S.
Securities and Exchange Commission (“SEC”) and the U.S. Department of Justice (“DOJ”) in October 2016. The Company
conducted, with the assistance of external counsel, an internal investigation and found no evidence corroborating any
involvement by the Company or its directors, officers or employees in respect of improper payments. An internal
investigation commissioned by Petrobras also found no evidence that Confab obtained any unfair commercial benefit or
advantage from Petrobras in return for payments, including improperly obtained contracts. On June 2, 2022, the
Company resolved the investigation by the SEC, and the DOJ informed that it had closed its parallel inquiry without taking
action. Under the settlement with the SEC, the Company neither admits nor denies the SEC’s findings and on June 24,
2022, paid $53.1 million in disgorgement and prejudgment interest and $25 million for a civil penalty to conclude the
matter.
In July 2019, the Company learned that the public prosecutors’ office of Milan, Italy, had completed a preliminary
investigation into the same alleged payments and had included in the investigation, among other persons, the Company’s
Chairman and Chief Executive Officer, two other board members, Gianfelice Rocca and Roberto Bonatti, and the
Company’s controlling shareholder, San Faustin. The Company is not a party to the proceedings. On March 22, 2022,
upon completion of the evidentiary phase of the trial, the acting prosecutor requested the first-instance court in Milan
in charge of the case to impose sanctions on the Company’s Chairman and Chief Executive Officer, on the other two board
members, and on San Faustin. The Company’s outside counsel in Italy advised the Company that neither the case file nor
the prosecutor’s request contain or identify any evidence of involvement in, or knowledge of, the alleged wrongdoing by
any of the three directors. On May 26, 2022, the first-instance court dismissed the case brought by the public prosecutor
against the defendants for lack of jurisdiction and stated that the criminal proceeding should not have been initiated. On
October 7, 2022, the public prosecutor filed an appeal against the first-instance court’s decision.
In June 2020, the Brazilian public prosecutorsoffice requested the indictment of several individuals, including three
executives or former executives of Confab and a former agent of Confab, charging them with the alleged crimes of
corruption in relation to contracts executed between 2007 and 2010, and money laundering in relation to payments
between 2009 and 2013. These criminal proceedings are underway. Neither the Company nor Confab is a party to these
criminal proceedings.
In addition, Petrobras and the Brazilian public prosecutors filed civil claims for damages against, among others, Confab
and the Confab executives named in the criminal proceedings referred to above. Confab became aware of these civil
claims in September 2022. As of December 31, 2022, the aggregate amount of these claims was estimated at BRL284.2
million (or approximately $54.5 million). The plaintiffs also seek that Confab be prohibited from contracting with, or
receiving benefits or exemptions from, the Brazilian state for an unspecified term. Confab believes these claims do not
address either the defense arguments or the evidence available to the plaintiffs in Brazil and presented in other
jurisdictions and is vigorously contesting them. At this stage, the Company cannot predict the outcome of these civil
proceedings.

Putative class actions
Following the Company’s November 27, 2018, announcement that its Chairman and CEO Paolo Rocca had been included
in an Argentine court investigation known as the Notebooks Case (a decision subsequently reversed by a higher court),
two putative class action complaints were filed in the U.S. District Court for the Eastern District of New York. On April 29,
2019, the court consolidated the complaints into a single case, captioned In re Tenaris S.A. Securities Litigation”, and
appointed lead plaintiffs and lead counsel. On July 19, 2019, the lead plaintiffs filed an amended complaint purportedly
on behalf of purchasers of Tenaris securities during the putative class period of May 1, 2014, through December 5, 2018.
The individual defendants named in the complaint are Tenaris’s Chairman and CEO and Tenaris’s former CFO. The
complaint alleges that during the class period, the Company and the individual defendants inflated the Tenaris share
price by failing to disclose that the nationalization proceeds received by Ternium (in which the Company held an 11.46%
stake) when Sidor was expropriated by Venezuela were received or expedited as a result of allegedly improper payments
made to Argentine officials. The complaint does not specify the damages that plaintiff is seeking. On October 9, 2020, the
court granted in part and denied in part the defendants’ motions to dismiss. The court partially granted and partially
denied the motion to dismiss the claims against the Company and its Chairman and CEO. In addition, the court granted
the motions to dismiss as to all claims against San Faustin, Techint, and Tenaris’s former CFO. On November 11, 2022,
the parties filed a joint notice of settlement announcing a settlement in principle of all claims in the action, subject to
finalizing the settlement agreements and court approval. The parties’ agreement in principle provides that, in exchange
for dismissal of the action and customary releases from class members and with no admission of liability by Tenaris or
Mr. Rocca, Tenaris will pay to the class $9.5 million (inclusive of legal fees to lead plaintiff’s counsel). On March 10, 2023,
the lead plaintiffs filed a motion for preliminary approval of the class settlement.
Administrative proceeding concerning Brazilian tax credits
Confab is a party to an administrative proceeding concerning the recognition and transfer of tax credits for an amount
allegedly exceeding the amount that Confab would have been entitled to recognize and / or transfer. The proceeding
resulted in the imposition of a fine against Confab representing approximately 75% of the allegedly undue credits, which
was appealed by Confab. On January 21, 2019, Confab was notified of an administrative decision denying Confab’s appeal,
thereby upholding the tax determination and the fine against Confab. On January 28, 2019, Confab challenged such
administrative decision and is currently awaiting a resolution. In case of an unfavorable resolution, Confab may appeal
before the courts. The estimated amount of this claim is BRL59.2 million (approximately $11.3 million). At this stage, the
Company cannot predict the outcome of this claim.
U.S. patent infringement litigation
Tenaris Coiled Tubes, LLC (“TCT”), a U.S. subsidiary of the Company, was sued in 2017 by its competitor Global Tubing,
alleging defamatory conduct by TCT and seeking a declaration that certain Global Tubing products do not infringe patents
held by TCT. TCT counterclaimed that certain Global Tubing products did infringe patents held by TCT, and Global Tubing
has since sought to invalidate such patents. On December 13, 2019, Global Tubing filed an amended complaint (including
the Company as defendant), alleging, among other things, that TCT and the Company had misled the patent office. On
March 20, 2023, the judge granted summary judgment in favor of Global Tubing, concluding that the patents at issue are
unenforceable due to inequitable conduct during the patent prosecution process. TCT and the Company are analyzing
whether to appeal this judgment. Although it is not possible to predict the final outcome of this matter, the Company
believes that any potential losses arising from this case will not be material.

U.S. Antidumping Duty and Countervailing Duty Investigations
On October 27, 2021, the U.S. Department of Commerce (“DOC”) announced the initiation of antidumping duty
investigations of oil country tubular goods (“OCTG”) from Argentina, Mexico, and Russia and countervailing duty
investigations of OCTG from Russia and South Korea. The investigations were initiated on the basis of a petition by U.S.
Steel Tubular Products, Inc., a small number of other U.S. domestic welded OCTG producers, and a steelworkers’ union.
On November 22, 2021, the International Trade Commission (“ITC”) made a preliminary determination of injury, allowing
the investigations to proceed. Subsequently, the DOC issued affirmative preliminary and final antidumping
determinations with respect to imports from Argentina, Mexico and Russia, and final affirmative countervailing duty
determinations with respect to imports from Russia and from some Korean exporters. On October 27, 2022, the ITC
determined that the imports under investigation caused injury to the U.S. OCTG industry, bringing the investigation phase
to a conclusion. Tenaris and other parties have appealed the agency determinations from the investigation to the Court
of International Trade. As a result of the investigation, and unless overturned on appeal, Tenaris is required to pay
antidumping duty deposits (at a rate of 78.30% for imports from Argentina and 44.93% for imports from Mexico) until
such time the imports are reviewed by the DOC to determine whether final duties are necessary for the specific period
under review. Tenaris has been paying such deposits since May 11, 2022, reflecting the amount of such deposits in its
costs. The deposit rates may be reset periodically based on the results of the review process. It is possible that, through
the periodic review process, the deposits may be either returned to Tenaris in whole or in part, or may be increased.

(ii) Commitments and guarantees
Set forth is a description of the Tenaris’s main outstanding commitments:
Certain subsidiaries of the Company entered into a contract with Praxair S.A. for the service of oxygen and nitrogen
supply. As of December 31, 2022, the aggregate amount to take or pay the committed volumes for an original 14-year
term totaled approximately $36.4 million.
A subsidiary of the Company entered into a 25-year contract (effective as of December 1, 2016, through December 1,
2041) with Techgen for the supply of 197 MW (which represents 22% of Techgen’s capacity). Monthly payments are
determined on the basis of capacity charges, operation costs, back-up power charges, and transmission charges. As of
the seventh contract year (as long as Techgen’s existing or replacing bank facility has been repaid in full), the Company’s
subsidiary has the right to suspend or early terminate the contract if the rate payable under the agreement is higher
than the rate charged by the Comisión Federal de Electricidad (“CFE”) or its successors. The Company’s subsidiary may
instruct Techgen to sell to any affiliate, to CFE, or to any other third party all or any part of unused contracted energy
under the agreement and the Company’s subsidiary will benefit from the proceeds of such sale.
A U.S. subsidiary of the Company is a party to a contract with Nucor Steel Memphis Inc. under which it is committed to
purchase on a monthly basis a specified minimum volume of steel bars, at prices subject to quarterly adjustments. The
contract became effective upon delivery of the first purchase order, which occurred in April 2021, and will remain in
force for a 3-year term. As of December 31, 2022, the estimated aggregate contract amount calculated at current prices,
is approximately $85.8 million. The contract gives the subsidiary of the Company the right to temporarily reduce the
quantities to be purchased thereunder to 75% of the agreed-upon minimum volume in cases of material adverse
changes in prevailing economic or market conditions.
In connection with the closing of the acquisition of IPSCO, a U.S. subsidiary of the Company entered into a 6-year master
distribution agreement (the “MDA”) with PAO TMK (“TMK”) whereby, since January 2, 2020, Tenaris is the exclusive
distributor of TMK’s OCTG and line pipe products in United States and Canada. At the end of the MDA’s 6-year term,
TMK will have the option to extend the duration of its term for an additional 12-month period. Under the MDA, the
Company is required to purchase specified minimum volumes of TMK-manufactured OCTG and line pipe products,
based on the aggregate market demand for the relevant product category in the United States in the relevant year. In
February 2022, however, the Company and TMK agreed that there shall be no minimum yearly purchase requirement
for the OCTG product category for the year ending December 31, 2022, and there shall be no minimum yearly purchase
requirement for TMK line pipe products under the MDA neither for the contract year ending December 31, 2022, nor
for any subsequent contract year until expiration of the MDA’s term.

A subsidiary of the Company entered into a contract with the supplier Voestalpine Grobblech GmbH from which it
committed to purchase carbon steel for a remaining amount of approximately $30.2 million to use for manufacturing
pipes related to the NFXP-QatarGas project.
Certain subsidiaries of the Company entered into agreements with Vestas Group for the supply of materials and services
related to the construction of a wind farm in Argentina. As of December 31, 2022, the remaining amount related to this
commitment was $47.7 million.
Certain subsidiaries of the Company entered into a one-year contract, renewable for one additional year, with Ternium
USA, Inc., under which they are committed to purchase on a monthly basis specified minimum volumes of steel coils.
The contract is effective since March 2022, with deliveries beginning in July 2022 until June 2023. As of December 31,
2022, the aggregate commitment totaled approximately $6.3 million.
Certain subsidiaries of the Company entered into a contract with Usiminas from which they committed to purchase
steel coils for a total amount of approximately $183.6 million to use for manufacturing welded pipes for the
construction of the Presidente Nestor Kirchner Gas Pipeline (“GPNK”) in Argentina.
A subsidiary of the Company entered into a contract with the supplier JFE Steel Corporation for the purchase tubular
material, including 13 Chrome alloy products following the closure of NKKTubes. For more information see note 35
“Other Information Agreement to terminate NKKTubes joint venture”.
In addition, Tenaris (i) applied for stand-by letters of credit as well as corporate guarantees covering certain obligations
of Techgen as described in note 13 (c), (ii) issued corporate guarantees securing certain obligations of GPC, as described
in note 13 (d) and (iii) issued performance guarantees mainly related to long-term commercial contracts with several
customers and parent companies for approximately $3.6 billion as of December 31, 2022.

(iii) Restrictions on the distribution of profits and payment of dividends
In accordance with Luxembourg Law, the Company is required to transfer a minimum of 5% of its net profit for each
financial year to a legal reserve until such reserve equals 10% of the issued share capital.
As of December 31, 2022, this reserve is fully allocated and additional allocations to the reserve are not required under
Luxembourg law. Dividends may not be paid out of the legal reserve.
The Company may pay dividends to the extent, among other conditions, that it has distributable retained earnings
calculated in accordance with Luxembourg law and regulations.

27 Cancellation of title deed in Saudi Steel Pipe Company
In early 2021, the Company learned through the Saudi Ministry of Justice’s online portal that the electronic title deeds to
certain land plots of its Saudi Arabian subsidiary SSPC had become inactive due to cancellation by court order.
The affected land plots, with a total surface of 811,284 square meters, are located in Dammam, Saudi Arabia, and were
purchased from a private entity on February 2010, pursuant to a written purchase agreement duly executed by SSPC in
full compliance with the laws of the Kingdom of Saudi Arabia. The purchase of the land occurred before Tenaris’s
acquisition of a 47.79% interest in SSPC in 2019. The affected plots are not part of the production facility of SSPC, have
been partially used as a warehouse, and have a carrying value on Tenaris’s financial statements of $56.2 million.
As of the date hereof, neither the cancellation nor the court order have been notified to SSPC or otherwise been made
public by the authorities, and the legal basis for the court order is unknown. On May 4, 2021, SSPC filed a petition with
an ad-hoc newly-created special committee at the Saudi Ministry of Justice, seeking to have its title deeds reinstated. The
proceeding is still ongoing and, at this time, it is not possible to predict the outcome of this matter.

28 Foreign exchange control measures in Argentina
Beginning in September 2019, the Argentine government has imposed and continues to impose significant restrictions
on foreign exchange transactions. Restrictions have tightened significantly over time. The main currently applicable
measures are described below:
Foreign currency proceeds derived from exports of goods must be sold into the Argentine foreign exchange
market and converted into Argentine pesos within 60 days (if made to related parties) or 180 days (if made to
unrelated parties) from shipment date, or, if collected earlier, within five days of collection.
Foreign currency proceeds from exports of services must be sold into the Argentine foreign exchange market
and converted into Argentine pesos within five business days of collection.
Access to the Argentine foreign exchange market to pay for imports of services rendered by related parties
(including royalties) is generally subject to Argentine Central Bank approval. Effective October 17, 2022, the
Argentine Central Bank put in place a new regulation on import of services rendered by non-related parties,
pursuant to which the Argentine Central Bank may clear or not the payment of import of services and, if cleared,
may determine a payment term equal or different to that being requested. There are no rules on the conditions
upon which the Argentine Central Bank may clear or determine alternative payment terms. Effective November
1, 2022, this new regulation replaced previous rules.
Access to the Argentine foreign exchange market to pay for imports of goods is subject to several restrictions.
For example, advance payments or at sight cannot be made, and companies cannot access the official foreign
exchange market if they hold cash or investments in excess of $100 thousand. Earlier this year, the Argentine
government imposed additional limits to the amount of import payments that could be made by any single
company per month or per year; companies that exceed such limits were required to obtain import financing of
at least 180 days from the date of nationalization of the goods, except to the extent the goods qualify under a
very limited number of exceptions, such as the import of capital goods and certain raw materials. Effective
October 17, 2022, the Argentine government implemented a new system, known as the SIRA system, pursuant
to which the Argentine government may clear or not the payment of imports and, if cleared, may determine a
payment term equal or different to that being requested. There are no objective conditions upon which the
Argentine government may clear the payment of imports or determine alternative payment terms under the
SIRA system. The exceptions for the import of capital goods and certain raw materials, including many of those
used by the Company’s Argentine subsidiaries, still exist under the SIRA system.
Negotiations with the Argentine authorities to raise the foregoing limits and/or expand the list of exceptions to
obtain access to foreign currency to pay for import of goods (including raw materials to manufacture goods in
Argentina) are ongoing.
Access to the Argentine foreign exchange market to pay debt service (principal and interest) for financial debts
with related parties requires prior Argentine Central Bank approval, unless the loan proceeds are sold in the
Argentine foreign exchange market and converted into Argentine pesos after October 2, 2020, and such debts
carry an average life of no less than 2 years.
Debts with foreign creditors larger than $2 million maturing on or before December 31, 2023, need to be
refinanced in at least 60% of outstanding principal and for a minimum period of 2 years.
Access to the Argentine foreign exchange market to make dividend payments requires prior Argentine Central
Bank approval.
When required, Argentine Central Bank approvals are rarely, if ever, granted.
Tenaris’s financial position in Argentine peso as of December 31, 2022, amounted to a net short exposure of
approximately $127 million. As of December 31, 2022, the total equity of Argentine subsidiaries represented
approximately 10.6% of Tenaris’s total equity and the sales performed by Argentine subsidiaries during the year ended
on December 31, 2022, amounted approximately to 20% of Tenaris’s total sales. Assets and liabilities denominated in
Argentine peso as of December 31, 2022, have been valued at the prevailing official exchange rates.

Management continues to monitor closely the evolution of the main variables affecting its business, identifying the
potential impact thereof on its financial and economic situation and determining the appropriate course of action in each
case. The Company’s Consolidated Financial Statements should be read taking into account these circumstances.
This context of volatility and uncertainty remains in place as of the issue date of these Consolidated Financial Statements.
If restrictions to access the official foreign exchange market continue to be maintained, or are further tightened, our
Argentine subsidiaries could be restricted from making payment of imports for key steelmaking inputs (which would
adversely affect their operations), or would need to resort to alternative, more expensive arrangements (which would
adversely affect their results of operations).
On August 19, 2022, the Board of Directors of Siderca S.A.I.C., an Argentine subsidiary of the Company, approved the
distribution of a dividend in kind of approximately ARS7,394 million paid in Argentine sovereign bonds, which in the
Argentine market had a valuation of approximately $54.4 million. Considering that, as a result of the foreign exchange
restrictions described above, the value of such bonds in the international market was approximately $24.6 million, the
Company recorded a loss of approximately $29.8 million in Other Financial Results.

Acquisition of Parques Eólicos de la Buena Ventura S.A.
In connection with the construction of a wind farm in Argentina, in April 2022, Tenaris acquired 100% of the shares of
Parques licos de la Buena Ventura S.A. for a price of $4.1 million, which was fully paid. The fair value of the acquired
assets and liabilities amounted to $4.1 million, the same value of the consideration paid. Accordingly, no goodwill was
recognized.
Had the acquisition occurred on January 1, 2022, Tenaris’s unaudited pro forma net sales and net income from continuing
operations would not have changed materially.

34 Nationalization of Venezuelan subsidiaries
In May 2009, within the framework of Decree Law 6058, Venezuela’s President announced the nationalization of, among
other companies, the Company's majority-owned subsidiaries TAVSA - Tubos de Acero de Venezuela S.A. (“Tavsa”) and,
Matesi Materiales Siderúrgicos S.A (“Matesi”), and Complejo Siderúrgico de Guayana, C.A (“Comsigua”), in which the
Company has a non-controlling interest (collectively, the “Venezuelan Companies”). Tenaris and its wholly-owned
subsidiary, Talta - Trading e Marketing Sociedad Unipessoal Lda (“Talta”), initiated arbitration proceedings against
Venezuela before the ICSID in Washington D.C. in connection with these nationalizations and obtained favorable awards,
which are final and not subject to further appeals.
Matesi
On January 29, 2016, the tribunal released its award on the arbitration proceeding concerning the nationalization of
Matesi. The award upheld Tenaris’s and Talta’s claim that Venezuela had expropriated their investments in Matesi in
violation of Venezuelan law as well as the bilateral investment treaties entered into by Venezuela with the Belgium-
Luxembourg Economic Union and Portugal. The award granted compensation in the amount of $87.3 million for the
breaches and ordered Venezuela to pay an additional amount of $85.5 million in pre-award interest, aggregating to a
total award of $173 million (including $0.2 million of legal fees), payable in full and net of any applicable Venezuelan tax,
duty or charge. The tribunal granted Venezuela a grace period of six months from the date of the award to make payment
in full of the amount due without incurring post-award interest, and resolved that if no, or no full, payment is made by
then, post-award interest will apply at the rate of 9% per annum compounded at six-monthly rests from the date of the
award until payment in full. As of December 31, 2022, post-award interest calculated at the award rate amounted to
approximately $144.7 million and, accordingly, the total amount owed by Venezuela under the award as of December
31, 2022 was $317.7 million.
On June 8, 2018, Tenaris and Talta filed an action in federal court in the District of Columbia to recognize and enforce the
award in the United States. On July 17, 2020, the Court entered judgment recognizing the Matesi award. The judgment
orders Venezuela to pay to Tenaris and Talta an amount of $256.4 million, including principal and post-award interest
through the judgment date, and provides for post-judgment interest to accrue on this sum at the U.S. federal statutory
rate. As of December 31, 2022, post-judgement interest calculated at the U.S. judgment rate amounted to approximately
$0.9 million and, accordingly, the total amount owed by Venezuela under the U.S. judgment as of December 31, 2022
was $257.3 million. The U.S. judgment, however, may not be enforced in the United States to the extent prohibited by
the Venezuelan sanctions regulations issued by the U.S. Treasury Department’s Office of Foreign Assets Control currently
in effect.
Tavsa and Comsigua
On December 12, 2016, the tribunal issued its award upholding Tenaris’s and Talta’s claim that Venezuela had
expropriated their investments in Tavsa and Comsigua in violation of the bilateral investment treaties entered into by
Venezuela with the Belgium-Luxembourg Economic Union and Portugal. The award granted compensation in the amount
of $137 million and ordered Venezuela to pay an additional amount of $76 million in pre-award interest and to reimburse
Tenaris and Talta $3.3 million in legal fees and ICSID administrative costs. In addition, Venezuela was ordered to pay
interest from April 30, 2008 until the day of effective payment at a rate equivalent to LIBOR + 4% per annum. As of
December 31, 2022, post-award interest calculated at the award rate amounted to approximately $85.1 million and,
accordingly, the total amount owed by Venezuela under the award as of December 31, 2022 was $301.4 million.
On June 8, 2018, Tenaris and Talta filed an action in federal court in the District of Columbia to recognize and enforce the
award in the United States. On August 24, 2021, the court entered judgment in favor of Tenaris and Talta and against
Venezuela in the amount of $276.9 million, with post-judgment interest accruing from the date of judgment at the federal
statutory post-judgment interest rate. On November 5, 2021, the court, in response to a motion by Tenaris and Talta,
amended the judgment amount to $280.7 million, with post-judgment interest continuing to accrue from August 24,
2021 at the federal statutory post-judgment interest rate. As of December 31, 2022, post-judgement interest calculated
at the U.S. judgment rate amounted to approximately $0.2 million and, accordingly, the total amount owed by Venezuela
under the U.S. judgment as of December 31, 2022 was $280.9 million. The U.S. judgment, however, may not be enforced
in the United States to the extent prohibited by the Venezuelan sanctions regulations issued by the U.S. Treasury
Department’s Office of Foreign Assets Control currently in effect.

Transfer of the Awards and Judgements
On January 25, 2023, Tenaris and Talta entered into an awards purchase agreement with an unaffiliated purchaser
pursuant to which Tenaris and Talta agreed to sell all of their rights, title and interests in the above-referenced claims,
awards and judgements, including all post-award or post-judgement interest accruing on the awards and judgements,
for a purchase price of $81 million, plus a non-refundable signing payment of $1 million as reimbursement of expenses.
The transfer of the awards and judgements is subject to the Office of Foreign Assets Control (“OFAC”) approval, and
according to the agreement must be obtained by February 25, 2024. The uncertainty associated with the OFAC approval
is factored into the fair value determination of the related receivable. See note III.B.


35 Other relevant information
Agreement to terminate NKKTubes joint venture
Tenaris’s seamless pipe manufacturing facility in Japan, located in the Keihin steel complex owned by JFE Holdings Inc.
(“JFE”), is operated by NKKTubes, a company owned 51% by Tenaris and 49% by JFE. Steel bars and other essential inputs
and services for NKKTubes are supplied under a long-term agreement by JFE.
On March 27, 2020, JFE informed Tenaris of its decision to permanently cease as from JFE’s fiscal year ending March 2024
the operations of its steel manufacturing facilities located at the Keihin complex. In light of that development, Tenaris
and JFE engaged in discussions and ultimately determined that the project was no longer economically sustainable.
Accordingly, on November 2, 2021, Tenaris and JFE agreed to terminate amicably their joint venture and liquidate
NKKTubes, and on November 2, 2022, entered into a definitive wrap-up agreement. Under these agreements:
a) NKKTubes’ manufacturing and production operations were closed by June 30, 2022;
b) the lease agreement of the Keihin steel complex between JFE and NKKTubes was terminated as of September
30, 2022;
c) all tangible fixed assets owned by NKKTubes and placed in the Keihin steel complex were either purchased by
JFE or removed and disposed of;
d) NKKTubes started its liquidation process on November 30, 2022;
e) all agreements that allowed the operation of the joint venture will terminate progressively in accordance with
NKKTubes’ operational needs until liquidation is accomplished;
f) all agreements with local Japanese customers and subcontractors were terminated;
g) the intangible assets belonging to NKKTubes will be allocated between the parties based on agreements still
under negotiation; and
h) all related dissolution and liquidation costs were allocated between the parties.
In July, 2022, Tenaris and JFE entered into an agreement for the provision of tubular material, including 13 Chrome alloy
products, thereby ensuring a continued supply of such products to international customers after NKKTubes’ closure.
Management determined that the parties’ decision to terminate the NKKTubes joint venture constituted an impairment
indicator, conducted an impairment test, and as of December 2021, recognized a charge of approximately $57 million,
impacting NKKTubes’ property, plant and equipment and intangible assets.
During 2022, as result of NKKTubes’ closure, the currency translation adjustment reserve belonging to the shareholders
was reclassified to the income statement for an amount of $71.2 million.
As of December 31, 2022, the net non-controlling interests’ reserve amounts to approximately $13.2 million. This balance
will be reclassified through the Company’s results in the period when the final liquidation of NKKTubes occurs.

Agreement for acquisition of Benteler Steel & Tube Manufacturing Corporation
On July 7, 2022, the Company entered into a definitive agreement to acquire from Benteler North America Corporation,
a Benteler Group company, 100% of the shares of Benteler Steel & Tube Manufacturing Corporation, a U.S. producer of
seamless steel pipes. The agreement provided that either party could unilaterally terminate the agreement in case that
the conditions precedent to closing had not been satisfied by January 3, 2023. On February 5, 2023, Tenaris announced
that Benteler North America Corporation had exercised its right to unilaterally terminate, effective immediately, the
acquisition agreement and, accordingly, the transaction will not proceed.

36 The Russia-Ukraine armed conflict and its impact on Tenaris’s operations
On February 24, 2022, Russia launched a military attack on Ukraine. In response, several jurisdictions, including the United
States, the European Union and the United Kingdom imposed a wave of sanctions against certain Russian institutions,
companies and citizens. The Russian government retaliated by ordering several economic counter measures, including
restrictions on residents transferring foreign currency abroad.
Tenaris has so far found alternative sources in response to the interruption in supplies from Ukraine and the impact of
sanctions on supplies from Russia but may still be faced with supply delays or forced to pay higher prices to secure the
raw materials, in particular energy, required for its steelmaking operations. Although it is hard to predict how energy and
commodity prices will continue to behave as the conflict unfolds, higher prices and possible shortages of energy and raw
materials used in Tenaris’s steelmaking operations would result in higher production costs and potential plant stoppages,
affecting its profitability and results of operations.
Tenaris’s sales to Russian customers were not material in the year ended December 31, 2022. All sales to Russian
customers and all purchases from Russian suppliers were made in compliance with applicable regulations. There are no
significant exposures or credit loss effects related to Russian counterparties, and the conflict has not created any
uncertainty on the value of financial instruments. The currently ongoing events have not changed significant judgements
taken into consideration when performing impairments tests, nor have they raised going concern risks. In addition,
Tenaris is assessing the closure of its representative office in Moscow, which is currently not operative.
In light of the armed conflict and the designation of Severstal’s controlling shareholder as person subject to EU and UK
sanctions, in March 2022, Tenaris recorded an impairment in the amount of approximately $14.9 million in connection
with its investment in a joint venture in Russia with Severstal. See note 13.

37 Climate change
Tenaris carefully assesses the potential impact of climate change and energy transition on its business and on the risks to
its markets and its tangible and intangible assets, and adapts its business strategy accordingly.
In February 2021 Tenaris set a medium-term target to reduce its carbon emissions intensity rate by 30% by 2030,
compared to a 2018 baseline, considering Scopes 1 and 2 emissions plus Scope 3 emissions related to raw materials and
steel purchased from third parties. The Company aims to achieve this target by using a higher proportion of recycled steel
scrap in the metallic mix and by making investments to increase energy efficiency and the use of renewable energy in its
energy requirements. This medium-term target forms part of a broader objective of decarbonizing our operations and
reaching carbon neutrality. At the same time, the Company is increasing its sales for low-carbon energy applications, such
as hydrogen, geothermal and carbon capture and storage. These sales currently account for a relatively small proportion
of overall sales but are expected to grow in the coming years.
In its assessment, Tenaris also considers that the countries in which it operates and its customers are also establishing
their own decarbonization strategies and objectives, and that some customers are requesting specific information from
their suppliers, including Tenaris, concerning the carbon emissions and Environmental, Social and Governance (“ESG”)
practices in their supply chain, and that they may adjust their supply practices in light of that information.

205





The recoverable value assessments performed by the Company for purposes of the preparation of these financial
statements reflect management’s views on energy transition and climate change and their potential medium-and long-
term impact on Tenaris’s operations and its sales. In addition, the Company carefully monitors the medium-and long-
term outlook scenarios published by leading industry experts on how the energy transition could affect global demand
for energy and oil and gas and how this could affect the global demand for tubular products and its sales. Furthermore,
estimates and assumptions used in the Company’s impairment tests over long-lived assets and goodwill, useful lives of
assets, capital and research and development expenditures, inventory valuation, recovery of deferred tax assets and
provisions, and contingent liabilities are based on available information and current government regulations on energy
transition and climate-related matters, as well as on Tenaris’s current short-term investment plans. As of the date of
these financial statements, the Company does not believe that climate-related matters should trigger any material
adjustments to the conclusions of its impairment tests.

Contingencies, commitments and restrictions on the distribution of profits updates

Information contained in note 26 Contingencies, commitments and restrictions on the distribution of profits was
amended reflecting the latest updates on the following cases: “CSN claims relating to the January 2012 acquisition of
Usiminas”, “Putative class actions” and U.S. patent infringement litigation”.

Tenaris to Increase its participation in Usiminas control group
On March 30, 2023, the Company’s subsidiary, Confab, together with Tenaris’s affiliates Ternium Investments and
Ternium Argentina, all of which compose the T/T Group within Usiminas control group, entered into a share purchase
agreement to acquire from the NSC Group, pro rata to their current participations in the T/T Group, 68.7 million ordinary
shares of Usiminas at a price of BRL10 (approximately $1.9) per ordinary share. Pursuant to the transaction, Tenaris would
pay approximately BRL 110 million (approximately $21 million) in cash for 11 million ordinary shares, increasing its
participation in the Usiminas control group to 9.8%. Upon the closing of this transaction, the T/T Group will hold an
aggregate participation of 61.3% in the control group, with the NSC Group and Previdência Usiminas (Usiminas
employees’ pension fund) holding 31.7% and 7.1%, respectively. The transaction is subject to approval by Brazil’s antitrust
authorities and will be financed with cash on hand.

The Company will continue having significant influence over Usiminas and consequently will continue accounting for its
investment under the equity method.

At closing, the existing Usiminas shareholders agreement will be replaced by a new shareholders agreement setting forth
a new governance structure for Usiminas. The T/T Group will nominate a majority of the Usiminas board of directors, the
chief executive officer and four other members of the Usiminas board of officers. Of the positions allocated to the T/T
Group, Tenaris will retain the right to nominate one member of the Usiminas board of directors and one members of the
Usiminas board of officers. Ordinary decisions may be approved with a 55% majority of Usiminas’ control group shares.

This note was added subsequently to the approval of these Consolidated Financial Statements by the Company’s Board of Directors on February 15,
2023.

At any time after the second anniversary of the closing of the transaction, the T/T Group will have the right to buy the
NSC Group’s remaining interest in the Usiminas control group (153.1 million ordinary shares) at the higher of BRL10 per
share and the 40-trading day average price per share immediately prior to the date of exercising the option. In addition,
the NSC Group will have the right, at any time after the closing of the transaction, to withdraw its remaining shares from
the control group and sell them in the open market after giving the T/T Group the opportunity to buy them at the 40-
trading day average price per share, as well as the right, at any time after the second anniversary of the closing, to sell
such shares to the T/T Group at BRL10 per share. Confab will have the right to participate in each such transaction pro
rata to its current participation in the T/T Group.

The Company will account for the transaction if and when the conditions precedent to closing are satisfied and the
acquisition is completed.

In connection with our audit of the annual accounts, our responsibility is to read the other information
identified above and, in doing so, consider whether the other information is materially inconsistent with
the annual accounts or our knowledge obtained in the audit, or otherwise appears to be materially
misstated. If, based on the work we have performed, we conclude that there is a material misstatement
of this other information, we are required to report that fact. We have nothing to report in this regard.
Responsibilities of the Board of Directors and those charged with governance for the annual
accounts
The Board of Directors is responsible for the preparation and fair presentation of the annual accounts in
accordance with Luxembourg legal and regulatory requirements relating to the preparation and
presentation of the annual accounts, and for such internal control as the Board of Directors determines
is necessary to enable the preparation of annual accounts that are free from material misstatement,
whether due to fraud or error.
In preparing the annual accounts, the Board of Directors is responsible for assessing the Company’s
ability to continue as a going concern, disclosing, as applicable, matters related to going concern and
using the going concern basis of accounting unless the Board of Directors either intends to liquidate the
Company or to cease operations, or has no realistic alternative but to do so.
Those charged with governance are responsible for overseeing the Company’s financial reporting
process.
The Board of Directors is responsible for presenting the annual accounts in compliance with the
requirements set out in the Delegated Regulation 2019/815 on European Single Electronic Format
(ESEF Regulation).
Responsibilities of the “Réviseur d’entreprises agréé” for the audit of the annual accounts
The objectives of our audit are to obtain reasonable assurance about whether the annual accounts as
a whole are free from material misstatement, whether due to fraud or error, and to issue an audit report
that includes our opinion. Reasonable assurance is a high level of assurance but is not a guarantee that
an audit conducted in accordance with the EU Regulation No 537/2014, the Law of 23 July 2016 and
with ISAs as adopted for Luxembourg by the CSSF will always detect a material misstatement when it
exists. Misstatements can arise from fraud or error and are considered material if, individually or in the
aggregate, they could reasonably be expected to influence the economic decisions of users taken on
the basis of these annual accounts.
As part of an audit in accordance with the EU Regulation No 537/2014, the Law of 23 July 2016 and
with ISAs as adopted for Luxembourg by the CSSF, we exercise professional judgment and maintain
professional scepticism throughout the audit. We also:
identify and assess the risks of material misstatement of the annual accounts, whether due to fraud
or error, design and perform audit procedures responsive to those risks, and obtain audit evidence
that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material
misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve
collusion, forgery, intentional omissions, misrepresentations, or the override of internal control;

obtain an understanding of internal control relevant to the audit in order to design audit procedures
that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Company’s internal control;
evaluate the appropriateness of accounting policies used and the reasonableness of accounting
estimates and related disclosures made by the Board of Directors;
conclude on the appropriateness of the Board of Directors’ use of the going concern basis of
accounting and, based on the audit evidence obtained, whether a material uncertainty exists related
to events or conditions that may cast significant doubt on the Company’s ability to continue as a
going concern. If we conclude that a material uncertainty exists, we are required to draw attention in
our audit report to the related disclosures in the annual accounts or, if such disclosures are
inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to
the date of our audit report. However, future events or conditions may cause the Company to cease
to continue as a going concern;
evaluate the overall presentation, structure and content of the annual accounts, including the
disclosures, and whether the annual accounts represent the underlying transactions and events in a
manner that achieves fair presentation.
We communicate with those charged with governance regarding, among other matters, the planned
scope and timing of the audit and significant audit findings, including any significant deficiencies in
internal control that we identify during our audit.
We also provide those charged with governance with a statement that we have complied with relevant
ethical requirements regarding independence, and communicate to them all relationships and other
matters that may reasonably be thought to bear on our independence, and where applicable, actions
taken to eliminate threats or safeguards applied.
From the matters communicated with those charged with governance, we determine those matters that
were of most significance in the audit of the annual accounts of the current period and are therefore the
key audit matters. We describe these matters in our audit report unless law or regulation precludes
public disclosure about the matter.
We assess whether the annual accounts have been prepared, in all material respects, in compliance
with the requirements laid down in the ESEF Regulation.

Report on other legal and regulatory requirements
The consolidated management report is consistent with the annual accounts and has been prepared in
accordance with applicable legal requirements.
The Corporate Governance Statement is included in the consolidated management report. The
information required by Article 68ter Paragraph (1) Letters c) and d) of the Law of 19 December 2002
on the commercial and companies register and on the accounting records and annual accounts of
undertakings, as amended, is consistent with the annual accounts and has been prepared in accordance
with applicable legal requirements.
We have been appointed as “Réviseur d’Entreprises Agréé” by the General Meeting of the Shareholders
on 3 May 2022 and the duration of our uninterrupted engagement, including previous renewals and
reappointments, is 21 years.
We have checked the compliance of the annual accounts of the Company as at 31 December 2022 with
relevant statutory requirements set out in the ESEF Regulation that are applicable to annual accounts.
For the Company it relates to the requirement that annual accounts are prepared in a valid XHTML
format.
In our opinion, the annual accounts of the Company as at 31 December 2022 have been prepared, in
all material respects, in compliance with the requirements laid down in the ESEF Regulation.

NOTES TO THE ANNUAL ACCOUNTS
Note 1 General information
Tenaris S.A. (the “Company” or “Tenaris”) was established on December 17, 2001 under the name of Tenaris Holding S.A.
as a public limited liability company under Luxembourg’s 1929 holding company regime (société anonyme holding). On
June 26, 2002, the Company changed its name to Tenaris S.A. On January 1, 2011, the Company became an ordinary
public limited liability company (société anonyme).
Tenaris’s object is to invest mainly in companies that manufacture and market steel tubes and other related businesses.
The financial year starts on January 1 and ends on December 31 of each year.
Tenaris prepares and publishes consolidated financial statements which include further information on Tenaris and its
subsidiaries. The consolidated financial statements are available at the registered office of the Company, 26, Boulevard
Royal – 4th floor, L-2449, Luxembourg, Grand-Duchy of Luxembourg.
Note 2 Summary of significant accounting policies
2.1 Basis of presentation
These annual accounts have been prepared in accordance with Luxembourg legal and regulatory requirements under the
historical cost convention.
Accounting policies and valuation rules are, besides the ones laid down by the law of 19 December 2002, determined and
applied by the Board of Directors.
The preparation of these annual accounts requires management to make certain accounting estimates and assumptions
that might affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the reporting
dates, and the reported amounts of income and charges during the reporting years. Actual results may differ from these
estimates. The main area involving significant estimates or judgements is impairment of financial assets. During the
period there were no material changes in the significant accounting estimates.
2.2 Foreign currency translation
Assets and liabilities denominated in currencies other than the United States Dollar (“USD”) are translated into USD at
the rate of exchange at the balance sheet date except for tangible and intangible fixed assets and Shares in affiliated
undertakings which remain at the historical exchange rate on the day of incorporation. The resulting gains or losses are
reflected in the Profit and loss account for the financial year when they are realized. Solely the unrealized exchange losses
are recorded in the profit and loss account. Income and expenses in currencies other than the USD are translated into
USD at the exchange rate prevailing at the date of each transaction.
2.3 Financial assets
Shares in affiliated undertakings are valued at purchase or contribution price including the expenses incidental thereto.
The Company conducts impairment tests on its financial assets in accordance with Luxembourg legal and regulatory
requirements.
In case of other than a temporary decline in respect of the financial assets value, its carrying value will be reduced to
recognize this decline. If there is a change in the reasons for which the value adjustments were made, these adjustments
could be reversed, if appropriate.
2.4 Debtors
Debtors are valued at their nominal value. They are subject to value adjustments whenever their recovery is
compromised. These value adjustments are not continued if the reasons for which the value adjustments were made
have ceased to apply.

(*) On December 7, 2010, Tenaris entered into a master credit agreement with Tenaris Investments pursuant to which,
upon request from Tenaris, Tenaris Investments may, but shall not be required to, from time to time, make loans to
Tenaris. Any loan under the master credit agreement may be repaid or prepaid from time to time through a reduction of
the capital of Tenaris Investments by an amount equivalent to the amount of the loan then outstanding (including accrued
interest). As a result of reductions in the capital of Tenaris Investments made during the financial year ended December
31, 2022, in connection with cancellations of loans to Tenaris, the value of the participation of Tenaris in Tenaris
Investments decreased by USD 642 million.
As of December 31, 2022 Tenaris Investments reported an equity of USD 14.9 billion and an income for the financial year
of USD 510.4 million.
Note 4 Capital and reserves
The authorized capital of the Company amounts to USD 2.5 billion. The total authorized share capital of the Company is
represented by 2,500,000,000 shares with a par value of USD 1 per share. The total capital issued and fully paid-up at
December 31, 2022 was 1,180,536,830 shares with a par value of USD 1 per share.
The Board of Directors is authorized until June 12, 2025, to increase the issued share capital, through issues of shares
within the limits of the authorized capital.
Following the completion of the corporate reorganization, and upon its conversion into an ordinary Luxembourg
holding company, the Company recorded a special reserve for tax purposes in a significant amount.

December 31, 2022 - all amounts in U.S. dollars, unless otherwise stated
217
Note 5 Legal reserve
In accordance with Luxembourg law, the Company is required to set aside a minimum of 5% of its annual net profit for
each financial year to a legal reserve. This requirement ceases to be necessary once the balance on the legal reserve has
reached 10% of the issued share capital. The Company’s reserve has already reached this 10%. If the legal reserve later
falls below the 10% threshold, at least 5% of net profits must be allocated to the reserve. The legal reserve is not available
for distribution to the shareholders.
Note 6 Distributable amounts
Dividends may be paid by Tenaris upon the ordinary shareholders’ meeting approval to the extent distributable
retained earnings exist.
At December 31, 2022, the Company’s profit brought forward after deduction of the loss and the interim dividend for the
financial year totaled approximately USD 12.4 billion and the share premium reserve which is also distributable,
amounted to USD 0.6 billion.
Note 7 Dividend payment
On November 3, 2022, the Company’s Board of Directors approved the payment of an interim dividend of USD 0.17 per
share (USD 0.34 per ADS), or approximately USD 201 million, paid on November 23, 2022, with an ex-dividend date of
November 21, 2022.
On May 3, 2022, the Company’s Shareholders approved an annual dividend in the amount of USD 0.41 per share (USD
0.82 per ADS). The amount approved included the interim dividend previously paid in November 24, 2021 in the amount
of USD 0.13 per share (USD 0.26 per ADS). The balance, amounting to USD 0.28 per share (USD 0.56 per ADS), was paid
on May 25, 2022, for an amount of approximately USD 331 million. In the aggregate, the interim dividend paid in
November 2021 and the balance paid in May 2022 amounted to approximately USD 484 million.
On May 3, 2021, the Company’s Shareholders approved an annual dividend in the amount of USD 0.21 per share (USD
0.42 per ADS). The amount approved included the interim dividend previously paid in November 25, 2020 in the amount
of USD 0.07 per share (USD 0.14 per ADS). The balance, amounting to USD 0.14 per share (USD 0.28 per ADS), was paid
on May 26, 2021, for an amount of approximately USD 165 million. In the aggregate, the interim dividend paid in
November 2020 and the balance paid in May 2021 amounted to approximately USD 248 million.

Note 15 Putative class actions
Following the Company’s November 27, 2018, announcement that its Chairman and CEO Paolo Rocca had been included
in an Argentine court investigation known as the Notebooks Case (a decision subsequently reversed by a higher court),
two putative class action complaints were filed in the U.S. District Court for the Eastern District of New York. On April 29,
2019, the court consolidated the complaints into a single case, captioned “In re Tenaris S.A. Securities Litigation”, and
appointed lead plaintiffs and lead counsel. On July 19, 2019, the lead plaintiffs filed an amended complaint purportedly
on behalf of purchasers of Tenaris securities during the putative class period of May 1, 2014, through December 5, 2018.
The individual defendants named in the complaint are Tenaris’s Chairman and CEO and Tenaris’s former CFO. The
complaint alleges that during the class period, the Company and the individual defendants inflated the Tenaris share
price by failing to disclose that the nationalization proceeds received by Ternium (in which the Company held an 11.46%
stake) when Sidor was expropriated by Venezuela were received or expedited as a result of allegedly improper payments
made to Argentine officials. The complaint does not specify the damages that plaintiff is seeking. On October 9, 2020, the
court granted in part and denied in part the defendants’ motions to dismiss. The court partially granted and partially
denied the motion to dismiss the claims against the Company and its Chairman and CEO. In addition, the court granted
the motions to dismiss as to all claims against San Faustin, Techint, and Tenaris’s former CFO. On November 11, 2022,
the parties filed a joint notice of settlement announcing a settlement in principle of all claims in the action, subject to
finalizing the settlement agreements and court approval. The parties’ agreement in principle provides that, in exchange
for dismissal of the action and customary releases from class members and with no admission of liability by Tenaris or
Mr. Rocca, Tenaris will pay to the class USD 9.5 million (inclusive of legal fees to lead plaintiff’s counsel). On March 10,
2023, the lead plaintiffs filed a motion for preliminary approval of the class settlement.
Note 16 U.S. patent infringement litigation
Tenaris Coiled Tubes, LLC (“TCT”), a U.S. subsidiary of the Company, was sued in 2017 by its competitor Global Tubing,
alleging defamatory conduct by TCT and seeking a declaration that certain Global Tubing products do not infringe patents
held by TCT. TCT counterclaimed that certain Global Tubing products did infringe patents held by TCT, and Global Tubing
has since sought to invalidate such patents. On December 13, 2019, Global Tubing filed an amended complaint (including
the Company as defendant), alleging, among other things, that TCT and the Company had misled the patent office. On
March 20, 2023, the judge granted summary judgment in favor of Global Tubing, concluding that the patents at issue are
unenforceable due to inequitable conduct during the patent prosecution process. TCT and the Company are analyzing
whether to appeal this judgment. Although it is not possible to predict the final outcome of this matter, the Company
believes that any potential losses arising from this case will not be material.
Note 17 Petrobras-related proceedings and claims
The Company is aware that Brazilian, Italian and Swiss authorities investigated whether certain payments were made
prior to 2014 from accounts of entities presumably associated with affiliates of the Company to accounts allegedly linked
to individuals related to Petróleo Brasileiro S.A. (“Petrobras”) and whether any such payments were intended to benefit
the Company’s Brazilian subsidiary Confab.
Upon learning of the investigation, the Audit Committee of the Company's Board of Directors engaged external counsel
in connection with the Company’s review of these matters. In addition, the Company voluntarily notified the U.S.
Securities and Exchange Commission (“SEC”) and the U.S. Department of Justice (“DOJ”) in October 2016. The Company
conducted, with the assistance of external counsel, an internal investigation and found no evidence corroborating any
involvement by the Company or its directors, officers or employees in respect of improper payments. An internal
investigation commissioned by Petrobras also found no evidence that Confab obtained any unfair commercial benefit or
advantage from Petrobras in return for payments, including improperly obtained contracts. On June 2, 2022, the
Company resolved the investigation by the SEC, and the DOJ informed that it had closed its parallel inquiry without taking
action. Under the settlement with the SEC, the Company neither admits nor denies the SEC’s findings and on June 24,
2022, paid USD 53.1 million in disgorgement and prejudgment interest and USD 25 million for a civil penalty to conclude
the matter.

In July 2019, the Company learned that the public prosecutors’ office of Milan, Italy, had completed a preliminary
investigation into the same alleged payments and had included in the investigation, among other persons, the Company’s
Chairman and Chief Executive Officer, two other board members, Gianfelice Rocca and Roberto Bonatti, and the
Company’s controlling shareholder, San Faustin. The Company is not a party to the proceedings. On March 22, 2022,
upon completion of the evidentiary phase of the trial, the acting prosecutor requested the first-instance court in Milan
in charge of the case to impose sanctions on our Chairman and Chief Executive Officer, on the other two board members,
and on San Faustin. The Company’s outside counsel in Italy advised the Company that neither the case file nor the
prosecutor’s request contain or identify any evidence of involvement in, or knowledge of, the alleged wrongdoing by any
of the three directors. On May 26, 2022, the first-instance court dismissed the case brought by the public prosecutor
against the defendants for lack of jurisdiction and stated that the criminal proceeding should not have been initiated. On
October 7, 2022, the public prosecutor filed an appeal against the first-instance court’s decision.
In June 2020, the Brazilian public prosecutorsoffice requested the indictment of several individuals, including three
executives or former executives of Confab and a former agent of Confab, charging them with the alleged crimes of
corruption in relation to contracts executed between 2007 and 2010, and money laundering in relation to payments
between 2009 and 2013. These criminal proceedings are underway. Neither the Company nor Confab is a party to these
criminal proceedings.
In addition, Petrobras and the Brazilian public prosecutors filed civil claims for damages against, among others, Confab
and the Confab executives named in the criminal proceedings referred to above. Confab became aware of these civil
claims in September 2022. As of December 31, 2022, the aggregate amount of these claims was estimated at BRL 284.2
million (or approximately USD 54.5 million). The plaintiffs also seek that Confab be prohibited from contracting with, or
receiving benefits or exemptions from, the Brazilian state for an unspecified term. Confab believes these claims do not
address either the defense arguments or the evidence available to the plaintiffs in Brazil and presented in other
jurisdictions and is vigorously contesting them. At this stage, the Company cannot predict the outcome of these civil
proceedings.
Note 18 Nationalization of Venezuelan subsidiaries
In May 2009, within the framework of Decree Law 6058, Venezuela’s President announced the nationalization of, among
other companies, the Company's majority-owned subsidiaries TAVSA - Tubos de Acero de Venezuela S.A. (“Tavsa”),
Matesi Materiales Siderúrgicos S.A (“Matesi”), and Complejo Siderúrgico de Guayana, C.A (“Comsigua”), in which the
Company has a non-controlling interest (collectively, the “Venezuelan Companies”). Tenaris and its wholly-owned
subsidiary, Talta - Trading e Marketing Sociedad Unipessoal Lda (“Talta”), initiated arbitration proceedings against
Venezuela before the ICSID in Washington D.C. in connection with these nationalizations and obtained favorable awards,
which are final and not subject to further appeals.
On January 25, 2023, Tenaris and Talta entered into an awards purchase agreement with an unaffiliated purchaser
pursuant to which Tenaris and Talta agreed to sell all of their rights, title and interests in the above-referenced claims,
awards and judgements, including all post-award or post-judgement interest accruing on the awards and judgements,
for a purchase price of USD 81 million, plus a non-refundable signing payment of USD 1 million as reimbursement of
expenses. The transfer of the awards and judgements is subject to the Office of Foreign Assets Control (“OFAC”) approval,
and according to the agreement must be obtained by February 25, 2024.
Note 19 Off balance sheet commitments
The Company issued guarantees covering the funding obligations of Techgen S.A. de C.V. (“Techgen”), an associated
company of Tenaris, under a loan agreement between Techgen and various lenders. As of December 31, 2022 and 2021,
the amount guaranteed was approximately USD 10.3 million.
Note 20 The Russia-Ukraine armed conflict and its impact on Tenaris’s operations
On February 24, 2022, Russia launched a military attack on Ukraine. In response, several jurisdictions, including the United
States, the European Union and the United Kingdom imposed a wave of sanctions against certain Russian institutions,
companies and citizens. The Russian government retaliated by ordering several economic counter measures, including
restrictions on residents transferring foreign currency abroad.

Tenaris has so far found alternative sources in response to the interruption in supplies from Ukraine and the impact of
sanctions on supplies from Russia but may still be faced with supply delays or forced to pay higher prices to secure the
raw materials, in particular energy, required for its steelmaking operations. Although it is hard to predict how energy and
commodity prices will continue to behave as the conflict unfolds, higher prices and possible shortages of energy and raw
materials used in Tenaris’s steelmaking operations would result in higher production costs and potential plant stoppages,
affecting its profitability and results of operations.
Tenaris’s sales to Russian customers were not material in the year ended December 31, 2022. All sales to Russian
customers and all purchases from Russian suppliers were made in compliance with applicable regulations. There are no
significant exposures or credit loss effects related to Russian counterparties, and the conflict has not created any
uncertainty on the value of financial instruments. The currently ongoing events have not changed significant judgements
taken into consideration when performing impairments tests, nor have they raised going concern risks. In addition,
Tenaris is assessing the closure of its representative office in Moscow, which is currently not operative.
In light of the armed conflict and the designation of Severstal’s controlling shareholder as person subject to EU and UK
sanctions, in March 2022, Tenaris recorded an impairment in the amount of approximately USD 14.9 million in connection
with its investment in a joint venture in Russia with Severstal. See note 13 of the Company’s consolidated financial
statements.
Note 21 Climate change
Tenaris carefully assesses the potential impact of climate change and energy transition on its business and on the risks to
its markets and its tangible and intangible assets, and adapts its business strategy accordingly.
In February 2021 Tenaris set a medium-term target to reduce its carbon emissions intensity rate by 30% by 2030,
compared to a 2018 baseline, considering Scopes 1 and 2 emissions plus Scope 3 emissions related to raw materials and
steel purchased from third parties. The Company aims to achieve this target by using a higher proportion of recycled steel
scrap in the metallic mix and by making investments to increase energy efficiency and the use of renewable energy in its
energy requirements. This medium-term target forms part of a broader objective of decarbonizing our operations and
reaching carbon neutrality. At the same time, the Company is increasing its sales for low-carbon energy applications, such
as hydrogen, geothermal and carbon capture and storage. These sales currently account for a relatively small proportion
of overall sales but are expected to grow in the coming years.
In its assessment, Tenaris also considers that the countries in which it operates and its customers are also establishing
their own decarbonization strategies and objectives, and that some customers are requesting specific information from
their suppliers, including Tenaris, concerning the carbon emissions and Environmental, Social and Governance (“ESG”)
practices in their supply chain, and that they may adjust their supply practices in light of that information.
The recoverable value assessments performed by the Company for purposes of the preparation of these financial
statements reflects management’s views on energy transition and climate change and their potential medium- and long-
term impact on Tenaris’s operations and its sales. In addition, the Company carefully monitors the medium- and long-
term outlook scenarios published by leading industry experts on how the energy transition could affect global demand
for energy and oil and gas and how this could affect the global demand for tubular products and its sales. Furthermore,
estimates and assumptions used in the Company’s impairment tests are based on available information and current
government regulations on energy transition and climate-related matters, as well as on Tenaris’s current short-term
investment plans. As of the date of these financial statements, the Company does not believe that climate-related
matters should trigger any material adjustments to the conclusions of its impairment tests.

Alternative performance measures
EBITDA, Earnings before interest, tax, depreciation and amortization
EBITDA provides an analysis of the operating results excluding depreciation and amortization and impairments, as they
are non-cash variables which can vary substantially from company to company depending on accounting policies and
the accounting value of the assets. EBITDA is an approximation to pre-tax operating cash flow and reflects cash
generation before working capital variation. EBITDA is widely used by investors when evaluating businesses (multiples
valuation), as well as by rating agencies and creditors to evaluate the level of debt, comparing EBITDA with net debt.
EBITDA is calculated in the following manner:
EBITDA = Net income for the period + Income tax charge +/- Equity in Earnings (losses) of non-consolidated companies
+/- Financial results + Depreciation and amortization +/- Impairment charge/(reversal)
EBITDA is a non-IFRS alternative performance measure.

Net cash / (debt) position
This is the net balance of cash and cash equivalents, other current investments and fixed income investments held to
maturity less total borrowings. It provides a summary of the financial solvency and liquidity of the company. Net cash /
(debt) is widely used by investors and rating agencies and creditors to assess the company’s leverage, financial
strength, flexibility and risks.
Net cash/ debt is calculated in the following manner:
Net cash= Cash and cash equivalents + Other investments (Current and Non-Current) +/- Derivatives hedging
borrowings and investments Borrowings (Current and Non-Current).
Net cash is a non-IFRS alternative performance measure.

asset base. Free cash flow is calculated in the following manner:
Free cash flow = Net cash (used in) provided by operating activities Capital expenditures.
Free cash flow is a non-IFRS alternative performance measure. Net cash provided by operating activities for the year
2022 amounted to $1,167 million.
