GENERAL INFORMATION The National Gas Transmission Company - SNTGN Transgaz SA (`company`) has as main activity the transmission of natural gas. Also, the company maintains and operates the national gas transmission system and carries out research and design activities in the area of natural gas transmission. On 31 December 2021, the majority shareholder of the company is the Romanian state, through the General Secretariat of the Government. The company was established in May 2000, following several reorganizations of the gas sector in Romania: its predecessor was part of the former national gas monopoly SNGN Romgaz SA (`predecessor company`), which was reorganized under Government Decision 334/2000. The natural gas sector is regulated by the `National Energy Regulatory Authority` - `ANRE`. ANRE's main responsibilities are the following: - issuing or withdrawing licenses for companies operating in the natural gas sector; - publishing framework contracts for the sale, transmission, acquisition and distribution of natural gas; - setting the criteria, requirements and procedures related to the selection of eligible consumers; - setting the pricing criteria and the calculation methods for the natural gas sector. The company is headquartered in 1 C.I. Motaş Square, Mediaş, Romania. From January 2008, the company is listed at the Bucharest Stock Exchange, as a Tier 1 company, under the TGN symbol. On 18 December 2017, the limited liability company EUROTRANSGAZ SRL Chisinau (EUROTRANSGAZ S.R.L.) was established in the Republic of Moldova. SNTGN Transgaz SA Mediaș is the sole shareholder of EUROTRANSGAZ S.R.L. under EGMS Resolution no. 10/12 December 2017 on the establishment company. The core business of EUROTRANSGAZ is: 1. Natural gas production; natural gas transmission; natural gas distribution; natural gas storage; natural gas supply 2. Transmission through pipelines 3. Storage 4. Business and management consulting activities. The share capital of EUROTRANSGAZ S.R.L. as of 31 December 2021, amounts to 1.198.753.397 Moldovan lei (RON equivalent of lei 269.914.960), and is wholly owned by SNTGN Transgaz SA Medias - the founder of the company, as sole shareholder.

GENERAL INFORMATION (CONTINUED) By the Resolution of the Board of Administration of March 2018 the conclusion of the Vestmoldtransgaz sale - purchase contract and the payment of the price offered for privatization and all the taxes and charges related to the privatization process were approved. Under Resolution Resolutionno.39 / 05.09.2019, the Board of Administration of SNTGN Transgaz SA approved the empowerment of the administrators of Eurotransgaz (ETG) to register the sale- purchase contract and the transfer of ownership of the sole patrimonial complex SE Vestmoldtransgaz, and the performance of any action necessary for the reorganization of Vestmoldtransgaz (VTMG) as a limited liability company. In 2021 the European Bank for Reconstruction and Development (EBRD) became a 25% shareholder of Vestmoldtransgaz S.R.L., by depositing funds in amount of MDL 414.986.000, of which MDL 394.178.670 was recorded as a contribution to the statutory capital and the difference of MDL 20.807.330 was recognized as capital premia. For the purpose of consolidating this set of financial statements, the non-controlling interest in the Group's share capital in amount of MDL 380.437.279 represents EBRD's share in the total net assets of the Company. The consolidation method applied is the global integration method, based on a percentage of the parent company's control higher than 50%. 2. OPERATIONAL FRAMEWORK OF THE COMPANY Romania The continuation of the economic reforms by the Romanian authorities is necessary for the consolidation of the internal macro-financial framework. Thus the premises of the correct administration of the possible unfavourable developments are created, developments, which may appear if the high aversion towards risk occurs again in the international financial markets. The positive performances the Romanian economy registered must be consolidated by the application of a coherent mix of policies. In this context it can be noticed that: (i) Accelerating the pace of structural reforms and effective investment of EU funds in parallel with efficient fiscal management will help strengthen the recovery and future growth, which will create better opportunities for progress for Romanians, according to the latest OECD report. Romania made remarkable progress in raising living standards before the COVID-19 crisis, and economic resilience during the pandemic was impressive. Romania lags behind most OECD countries when it comes to providing access to high quality education, health, housing and transport, the document says. To sustain recovery in the medium and long term, Romania needs

OPERATIONAL FRAMEWORK OF THE COMPANY (CONTINUED) to focus on effective implementation of the EU-funded National Recovery and Resilience Plan, by improving administrative capacity and carrying out necessary reforms in areas such as pensions. Reforms must also focus on restoring productivity growth, job creation and skills development, strengthening the rule of law and public finances. The study forecasts 4,5% GDP growth for Romania in 2022 and 2023, after a 6,3% increase in 2021. In view of the strong rise in inflation, which has exceeded the target set by the NBR, monetary policy needs to be tightened as needed. A credible medium-term plan needs to be developed to allow a gradual reduction of the budget deficit. This plan should include reforms aimed at accelerating the absorption of EU NextGeneration funds, improving the efficiency of public spending and improving the financial sustainability of the pension system in an ageing population. Accelerating the modernisation of the tax administration, as well as reforms aimed at removing inefficient tax provisions (in particular those targeting micro-enterprises and certain sectors such as construction) and increasing less distortionary taxes (such as property taxes) could contribute to raising revenue and creating a fairer and more efficient tax system. Improving skills and job opportunities would also help reduce the flow of Romanian migrants, which has already affected economic development through labour and skills crises, the OECD paper shows. (ii) On 10 January 2022, the Board of the National Bank of Romania decided:  to increase the monetary policy rate to 2,00 % per year, from 1,75% per year from 11 January 2022;  extending the symmetric corridor of standing facility interest rates around the monetary policy interest rate to ±1,00 percentage point from ±0,75 percentage points; thus, as of 11 January 2022, the interest rate on the lending facility (Lombard) is increased to 3,00 per cent per annum from 2,50 per cent per annum and the interest rate on the deposit facility is maintained at 1,00 per cent per annum;  maintaining firm control over money market liquidity;  maintaining the current levels of the mandatory minimum reserves for the lei and currency liabilities of the credit institutions; (iii) In view of the November 2021 NBR Inflation Report, the annual CPI inflation rate accelerated significantly in the third quarter of 2021 to 6,29 percent in September, with the deviation from the upper bound of the range associated with the steady-state target increasing in each month of the quarter. In September, the annual inflation rate advanced by 2,35 percentage points from June's value, while registering a level 1 percentage point higher than projected in the August Report. The primary source of the increase remained, similar to the first two quarters of the year, the notable rise in energy commodity prices, at a time when at the end of September the wholesale price of electricity and natural gas was up to two to three times higher than at the end

OPERATIONAL FRAMEWORK OF THE COMPANY (CONTINUED) of the previous year. During the same period, a substantial advance in the CORE2-adjusted annual inflation rate was also visible, from 2,9 percent in June to 3,6 percent in September. The average annual CPI inflation rate continued its upward trajectory during the third quarter, reaching 3,6 percent in September. The average annual rate of HICP inflation increased by 0,5 percentage point from June to 2,9 percent in September. As price increases in the EU were more marked, Romania narrowed marginally its gap with the European average. (iv) Fitch Ratings confirmed on 22 October 2021 Romania's sovereign rating at `BBB minus` with a negative outlook, the last notch of the `investment-grade` category, according to a statement issued by the financial rating agency. The negative outlook reflects continued uncertainty over the implementation of policies to address structural fiscal imbalances on the medium term and the impact on Romania's public finances from persistent pandemic-related risks and rising energy costs, Fitch said. The investment-grade rating is supported by government debt and debt service levels, which are below those of similarly rated countries, and GDP per capita, governance and human development indicators, which are above those of similarly rated countries and are supported by EU membership. The rating agency affirms that these are offset by high budget and current account deficits, a low level of fiscal consolidation and high budget rigidities. At the end of 2020, the leu depreciated against the EURO (`EUR`) and appreciated against the US dollar (`USD). Thus, compared to the end of 2019, the leu depreciated by 1,89% against the EUR (4,8694 at 31 December 2020; 4,7793 at 31 December 2019) and appreciated by 6,92% against the USD (3,9660 on 31 December 2020; 4,2608 on 31 December 2019). At the end of 2021, the leu depreciated against the EURO (`EUR`) as well as against the US dollar (`USD). Thus, compared to the end of 2020, the leu depreciated by 1,62% against the EUR (4,9481 at 31 December 2021; 4,8694 at 31 December 2020) and by 10,20% against the USD (4,3707 on 31 December 2021; 3,9660 on 31 December 2020). 3. SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES The main accounting policies applied in the preparation of these financial statements are presented below. These policies were consistently applied to all the financial years considered, unless otherwise stated.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (expressed in lei, unless otherwise stated) This version of the interim consolidated financial statements is a translation from the original, which was prepared in Romanian. All possible care has been taken to ensure that the translation is an accurate representation of the original. However, in all matters of interpretation of information, views or opinions, the original language version of our report takes precedence over this translation. (10) 3. SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) 3.1 Basis of preparation The financial statements of the company were prepared in accordance with the International Financial Reporting Standards adopted by the European Union (`EU IFRS`). The financial statements were prepared based on the historical cost convention, except for the financial assets which are measured at fair value by the profit and loss account or at the fair value among other elements of the comprehensive income. The preparation of the financial statements in accordance with EU IFRS requires the use of critical accounting estimates. Also, the management is required to use judgment in applying the company's accounting policies. Areas with a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the financial statements are presented in Note 5. From 2017, the year when EUROTRANSGAZ was founded by SNTGN Transgaz SA, the company has the obligation to prepare the consolidated financial statements in accordance with IFRS 10 - Consolidated Financial Statements, IFRS 12 - Disclosure of Interests in Other Entities and IAS 21 – The Effects of Changes in Foreign Exchange Rates. From 2018, as a result of the procurement of Vestmoldtransgaz SRL in Moldova by Eurotransgaz SRL, Transgaz, as a parent company, presented consolidated financial statements which include the consolidation of Eurotransgaz SRL with Vestmoldtransgaz SRL in Moldova. Transgaz’s consolidation with ETG was performed step by step, meaning the consolidation of ETG with VTMG in a first phase, followed by their consolidation in the financial statements of the parent company, Transgaz. The annual Financial Statements of non-resident companies are converted using the closing rate method, which means that for the balance sheet the NBR exchange rate issued on 31 December 2021 is used (closing rate) and for the profit and loss account the income and expense was expressed at the annual average rate published by the National Bank of Romania for 2021. The use of these different exchange rates has as a consequence the highlighting of the conversion difference. According to Accounting Law 82/1991 republished, as further amended and supplemented, and to OMFP 2844/2016, as further amended and supplemented, on the approval of the accounting regulations in line with the International Financial Reporting Standards, the parent company must prepare both its own individual financial statements and consolidated financial statements of the group. IFRS 10 sets out the application of the control principle to determine whether an investor controls an investee and therefore needs to consolidate the investee and also sets the accounting provisions for the preparation of the consolidated financial statements.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (expressed in lei, unless otherwise stated) This version of the interim consolidated financial statements is a translation from the original, which was prepared in Romanian. All possible care has been taken to ensure that the translation is an accurate representation of the original. However, in all matters of interpretation of information, views or opinions, the original language version of our report takes precedence over this translation. (11) 3. SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) The parent company must prepare consolidated financial statements using uniform accounting policies for transactions and similar events in similar circumstances. The consolidation of an investee must start at the date the investor has acquired control and must cease when the investor loses control of the investee. The parent company must disclose the interests that do not control in the consolidated statement of financial position within equity, separately from the equity of the owners of the parent company. Changes in a parent's equity interest in a subsidiary that do not result in the parent company's loss of control of the subsidiary are equity transactions (ie transactions with owners in their capacity as owners). If a parent company loses control over a subsidiary, the parent company must: (a) derecognise the assets and liabilities of the former subsidiary from the consolidated financial position; (b) recognize any undistributed investment in the former subsidiary at its fair value when it has lost control and will subsequently account for those investments and the amounts owed by or to the former subsidiary in accordance with the relevant IFRSs. That fair value should be considered as the fair value at the time of the initial recognition of a financial asset in accordance with IFRS 9 or, where applicable, the cost of the initial recognition of an investment in an associate or in a joint venture; (c) recognizes the gain or loss associated with the loss of control attributable to the former majority interest. The consolidated financial statements include the Company`s financial statements and the financial statement of the affiliated entity, EUROTRANSGAZ, which is controlled by the company, combining similar parent company – affiliated company assets, liabilities, equity, costs and cash flow items, compensating (eliminating) the accounting value of the investment made by the parent company in each subsidiary, and the share of the parent company in the equity of each subsidiary, and eliminating in full all intragroup assets and liabilities, equity and cash flows related to the intragroup transactions performed. A company controls an entity in which it had invested when it is exposed or has variable income rights on the basis of its participation in the investee and has the ability to influence the relevant income through its authority over the investee. The control principle thus establishes the following three elements of control: 1. the authority over the investee; 2. the exposure or variable income rights based on participation in the investee; and 3. the ability to use the authority over the investee to influence the value of the investor's results. The company presents the investments in the the affiliated entity in the individual financial statements as Financial Assets. IFRS 3 requires the acquirer, after recognizing the identifiable assets, the liabilities and all interests, which do not control, to identify any differences between:

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) a) the aggregation of the transferred counter-performance, any interest which does not control in the acquired entity and in a business combination made in stages, the fair value from the acquisition date of the equity interests of the acquired entity previously held by the acquirer, and b) the net identifiable net assets acquired. Generally, the difference will be recognized as a goodwill. In accordance with IAS 36 - Impairment of Assets, goodwill acquired in a business combination will be tested for depreciation annually. Consolidation procedures according to IFRS 10 The consolidated financial statements: -combine similar items of assets, liabilities, equity, income, expenses and cash flows of the parent company with those of its subsidiaries; - compensate (eliminate) the accounting amount of the investment made by the parent company in the subsidiary and the parent`s share of the equity of the subsidiary; accounting is according to IFRS 3; - eliminate in full all intragroup assets and liabilities, equity, income, expenses and cash flows relating to transactions between the entities of the group: profit or loss from the intragroup transactions recognised in the assets, such as inventories and the fixed assets are totally eliminated. Accounting regulations applicable as of 2016 Amendments to various Improvements to IFRS (2014-2016 Cycle) resulting from the project to improve IFRS (IFRS 1, IFRS 12, IAS 28) mainly to eliminate inconsistencies and to clarify certain formulations (Amendments to IFRS 12 are applicable for the annual periods beginning on or after 1 January 2017 and the Amendments to IFRS 1 and IAS 28 are applicable for the annual periods beginning on or after 1 January 2018). (a) Standards and interpretations applicable as of 2017 The following standards and amendments of the current standards, issued by the International Accounting Standard Board (`IASB`) and adopted by the European Union (EU ) became applicable in 2017: Amendments to IAS 12 `Income Taxes` Recognition of Deferred Tax Assets for Unrealised Losses (applicable for the annual periods beginning on or after 1 January 2017); Amendments to deferred tax recognition for unrealized assets clarify the following aspects:  Unrealized loss on debt instruments measured at fair value and at cost for tax purposes will give rise to a deductible temporary difference regardless of whether the holder of the debt instrument expects to recover the accounting value of the debit instrument by sale or by use;

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  The accounting value of an asset does not limit the estimation of the future taxable profits  Estimates of future taxable profits exclude tax deductions resulting from the lapse of taxable temporary differences;  The entity estimates a deferred tax in combination with other deferred taxes. Where tax law restricts the use of tax loss, an entity will estimate deferred tax in combination with other deferred tax of the same type. The Amendments are applicable for the period starting from or after 2017. The previous application is allowed; The amendments to IAS 7 Statement of Cash Flows – Disclosure Initiative (applicable for the annual periods beginning on or after 1 January 2017); (b) Standards and interpretations applicable as of 2018 At the date of reporting of these Financial Statements, the following standards, revisions and interpretations became applicable: IFRS 9 Financial Instruments - adopted by the UE on 22 November 2016 (applicable for the annual periods beginning on or after 1 January 2018) replaces IAS 39 – Financial Instruments - Recognition and Measurement; IFRS 9 includes the requirements on financial instruments referring to recognition, classification, evaluation, depreciation loss, derecognition and hedge accounting against risks:  Classification and evaluation: IFRS 9 introduces a new approach to the classification of financial assets and comprises three main categories of financial assets: measured at amortized cost, at fair value through other comprehensive income elements, at fair value through profit or loss. The IFRS 9 classification is determined by the cash flow and business model in which an asset is held. This unitary approach based on principles eliminates the financial asset classification categories in IAS 39: held-to-maturity, loans and advances and available-for-sale financial assets. The new model will also determine the existence of a single depreciation model applicable to all financial instruments.  According to IFRS 9, derivatives incorporated into contracts, where the host instrument is a financial instrument for the purpose of this standard, are not separate, but the entire hybrid instrument is considered for classification.  Depreciation loss: IFRS 9 introduces a new anticipated impairment loss model based on expected loss, which will require anticipated recognition of expected loss from impairment of receivables. The standard requires entities to recognize the anticipated impairment loss on receivables from the time of initial recognition of financial instruments, and to recognize the anticipated impairment loss over their lifetime.  The amount of expected loss will be updated for each reporting period so as to reflect changes in credit risk as compared to initial recognition.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  Depreciation: applies to commercial receivables that do not have a funding component is measured at amortized cost (the condition is that assets are held within a business model whose objective is to collect cash flows;  Hedge accounting: IFRS 9 introduces a significantly improved hedge accounting model which includes additional disclosure requirements for risk management activity. The new model is a significant revision of the hedge accounting principles, which allows the alignment of the accounting treatment with the risk management activities. IFRS 15 `Revenue from Contracts with Customers` with further amendments and with the amendments to IFRS 15 `Effective Date of IFRS 15` adopted by the EU on 22 September 2016 (applicable for the annual periods beginning on or after 1 January 2018); IFRS 15 establishes a single model for the entities for revenue accounting resulting from customer contracts, replacing the following standards and interpretations from the date of entry into force: - IAS 18 - Revenue; - IAS 11 - Construction Contracts - IFRIC 13 - Customer Loyalty Programmes; Standards and interpretations that will come into force/applicable from 2019 or at a future date - IFRIC 15 - Agreements for the Construction of Real Estate; - IFRIC 18 - Transfers of Assets from Customers; - SIC 31 – Income - Barter Transactions Involving Advertising Services The core principle of IFRS 15 is that an entity recognizes revenue when the goods or services promised to customers are transferred at a value that reflects the consideration the entity expects to have the right to exchange for those goods or services. An entity recognizes revenue in accordance with this core principle by applying the following steps: contract identification; identifying performance obligations from the contract; determining the transaction price; allocating the transaction price for the contract performance obligations; recognizing revenue when (or as) it fulfils an execution obligation. The revenue from services provision is recognized as follows: - based on the tariffs regulated by ANRE for firm/ interruptible natural gas transmission services through the National Transmission System; - based on the transmission tariffs approved by ANRE for the transmission capacity booking at the entry/ exit points in/out of the Isaccea 2-Negru Vodă 2 natural gas transmission pipeline;

For goods developed under the Concession Agreement, achieved in-house, the revenue is recognized at the level of the costs incurred. Amendments to IAS 40 ` Investment Property `–property related to Investment transactions (applicable for the annual periods beginning on or after 1 January 2018); IFRIC 22 `Foreign Currency Transactions and Advance Consideration` (applicable for the annual periods beginning on or after 1 January 2018); the interpretation refers to the determination of the transaction date to determine the exchange rate to be used for the initial recognition of an asset, expense or income (or part thereof) in the derecognition of a non-monetary asset or non-monetary debt generated by a payment in advance in foreign currency. IFRIC 22 does not provide for guidance on the definition of the monetary and non-monetary items. A payment or advance payment generally leads to the recognition of a non-monetary asset/liability, but it may also lead to the recognition of a monetary asset/liability. At the date of the reporting of these Financial Statements the following standards and interpretations are not applicable and they will enter into force on or after 1 January 2019:  IFRS 16 Leases (applicable for the annual periods beginning on or after 1 January 2019); at the date of entry into force IFRS 16 will replace the following standards and interpretations: - IAS 17 - Leases; - IFRIC 4- Determining whether an Arrangement Contains a Lease; - SIC 15 – Operating Leases - Incentives; - SIC 27- Evaluating the Substance of Transactions in the Legal Form of a Lease. IFRS 16 provides a model of control for lease identification by establishing principles for the recognition, measurement and presentation of lease contracts, that is the right to control the use of an identified asset for a period of time in exchange for consideration. The right to control the use of the identified asset exists if the client has the right to obtain substantially all the economic benefits and also the right to determine the manner and purpose in which the asset is used.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) IFRS 16 introduces significant changes in lease accounting, in particular by eliminating the distinction between finance lease and operating lease, and requires the lessee to recognize a usable asset and a lease liability at the date of commencement of the contract, except for short-term leases or low-value asset lease. As of 1 June 2020, IFRS 16 was amended to provide a practical expedient to lesees`s rent concessions ocurring as direct consequence of the COVID-19 pandemic andmeeting the following criteria: (a) the change in lease payments results in revised consideration for the lease that is substantially the same as, or less than, the consideration for the lease immediately preceding the change; (b) the reduction in lease payments relates only to payments due on or before 30 June 2021; and (c) there is no substantive change to other terms and conditions of the lease. Rent concessions meeting these criteria can be accounted according to the practical opportunity, which means that the lessee does not assess wether the rent concession meets the definition of a lease modification. The lesees apply other IFRS 16 requirements in the accounting of the accounting for the concession. Amendments to IFRS 2 `Share-based Payment` – Classification and measurement of share-based payment transactions (applicable for the annual periods beginning on or after 1 January 2018);  Amendments to IFRS 4 `Insurance Contracts` - Applying IFRS 9 Financial Instruments with IFRS 4 Insurance Contracts (applicable for the annual periods beginning on or after 1 January 2018 or at the application for the first time of IFRS 9 `Financial Instruments`;  Amendments to IFRS 10 `Consolidated Financial Statements` and IAS 28 `Investments in Associates and Joint Ventures`- Sale or contribution of assets between an investor and its associate or joint venture and its further amendments (the effective date was deferred indefinitely until completion of the research on the equity method);  IFRIC 23- `Uncertainty over Income Tax Treatment` was prepared as an interpretation regarding IAS 12 Income Taxes, to specify the way of the uncertainty over the income tax accounting is presented. The IFRS Interpretation Committee developed IFRIC 23 to clarify uncertainties over how tax law applies to a particular transaction or circumstance or the extent to which a tax authority will accept a company`s tax treatment company. IAS 12 Income Taxes specifies how to account for current and deferred tax, but not how to reflect the effects of uncertainty . In 2020, the IASB finalizes the amendments to IAS 1 and IAS 8 on the definition of `significant` `information is material if omitting, misstating or obscuring it could reasonably be expected to influence the decisions that the primary users of general purpose financial statements make on the basis of those financial statements, which provide financial information about a specific reporting entity based on that financial statement, which provide financial information about a particular reporting entity. `

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) New standards, interpretations and amendments with subsequent applicability. The company has chosen not to apply in advance these standards, interpretations and amendments to be subsequently applicable The following changes are valid for the period beginning on 1 January 2022: • Onerous contracts - Cost of Fulfilling a Contract (Amendments to IAS 37); • Tangible assets: proceeds before intended use (amendments to IAS 16); • Annual improvements to IFRS 2018-2020 (Amendments to IFRS 1, IFRS 9, IFRS 16 and IAS 41); and • Reference to the Conceptual Framework (Amendments to IFRS 3). The following changes are valid for the period beginning on 1 January 2023 The International Accounting Standards Board (IASB) issued Classification of Liabilities as Current or Non-Current (Amendments to IAS 1) providing a more general approach to the classification of liabilities in accordance with IAS 1 based on existing contractual arrangements in the Data Reporting. The changes were initially valid for annual reporting periods beginning on or after 1 January 2022. However, in May 2020, the effective date was postponed to annual reporting periods beginning on or after 1 January 2023: Changes in the Classification of Liabilities as Current or Non-Current (Amendments to IAS 1) affect only the presentation of liabilities in the statement of financial position - not the amount or timing of the recognition of any assets, income or expenses or the information that entities disclose about these items. The following is clarified: The classification of liabilities as current or non-current should be based on rights that exist at the end of the reporting period and the wording shall be aligned in all relevant paragraphs to refer to the `right` to defer settlement by at least twelve months and clarify that only the rights in force `at the end of the reporting period` should affect the classification of a debt; The classification is not affected by expectations that an entity will exercise its right to defer the settlement of a debt; Settlement refers to the transfer to the counterparty of the cash, equity instruments, other assets or services. An entity applies this interpretation for annual reporting periods beginning on at or after 1 January 2019. Application prior to this date is permitted. An `uncertain tax treatment` is a tax treatment for which there is uncertainty over whether the relevant taxation authority will accept the tax treatment under the tax law.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) 3.2 Reporting on segments Reporting on business segments is made consistently with the internal reporting by the main operating decision-maker. The main operating decision-maker, which is in charge with resource allocation and assessment of business segments' performance, was identified as being the Board of Administration, which makes the strategic decisions. 3.3 Transactions in foreign currency a) Functional currency The items included in the financial statements of the company are valued using the currency of the economic environment where the entity operates (`functional currency`). The financial statements are presented in Romanian leu (`lei`), which is the functional currency and the currency of company presentation. b) The rounding level used in the presentation of the financial statements In the financial statements the value are presented rounded by units. c) Transactions and balances Transactions in foreign currency are converted into functional currency using the exchange rate valid on the date of transactions or valuation at the balance sheet date. Profit and loss resulting from exchange rate differences following the conclusion of such transactions and from the conversion at the exchange rate at the end of the reporting period of monetary assets and liabilities denominated in foreign currency are reflected in the statement of the comprehensive income. 3.4 Accounting for the effects of hyperinflation Romania has gone through periods of relatively high inflation and was considered hyperinflationary under IAS 29 `Financial Reporting in Hyperinflationary Economies`. This standard required financial statements prepared in the currency of a hyperinflationary economy to be presented in terms of purchasing power as of 31 December 2003. As the characteristics of the economic environment in Romania indicate the cessation of hyperinflation, from 1 January 2004, the company no longer applies IAS 29. Therefore, values reported in terms of purchasing power on 31 December 2003 are treated as basis for the accounting values of these financial statements.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) 3.5 Intangible Assets Computer Software Licenses acquired related to rights of use of the computer software are capitalized on the basis of the costs incurred with the acquisition and operation of the software in question. These costs are amortized over their estimated useful lives (three years). Costs associated with developing or maintaining computer software are recognized as expenses in the period in which they are registered. Service Concession Agreement From 2010, the company started to apply IFRIC 12 Service Concession Arrangements, adopted by the EU. The scope of IFRIC 12 includes: the existing infrastructure at the time of signing the concession agreement and, also, the modernization and improvement brought to the gas transmission system, which are transferred to the regulatory authority at the end of the concession agreement. As presented in Note 8, the company is entitled to charge the users of the public service and, consequently, an intangible asset was recognized for this right. Due to the fact that the Service Concession Agreement (`SCA`) had no commercial substance (i.e. nothing substantial changed in the way the company operated assets; cash flows changed only with the payment of royalties, but, on the other hand, the transmission tariff increased to cover the royalty), the intangible asset was measured at the remaining net value of the derecognized assets (classified in the financial statements as tangible assets on the date of application of IFRIC 12). Consequently, the company continued to recognize the asset, but reclassified it as intangible asset. The company tested the intangible assets recognized at the time without identifying depreciation. As they occur, costs of replacements are recorded as expense, while the improvements of assets used within SCA are recognized at cost. Intangible assets are amortized at zero value during the remaining period of the concession agreement. 3.6 Tangible Assets Tangible assets include buildings, land, assets used for the non-regulated international transmission activity (e.g. pipelines, compressors, filtering installations, devices). The company’s policy is to reflect intangible assets at their cost less any accumulated depreciation and any impairment accumulated losses.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Buildings include particularly ancillary buildings of operating assets, a research centre and office buildings. Further expenses are included in the book value of the asset or recognized as separate asset, as the case may be, only when the entry of future economic benefits for the company associated to the item is likely and the cost of the respective item can be valued in a reliable manner. The book value of the replaced asset is taken off the books. All the other expenses with repairs and maintenance are recognized in the statement of comprehensive income in the financial period when they occur. Land is not depreciated. Depreciation on other items of tangible assets is calculated based on the straight-line method in order to allocate their cost minus the residual value, during their useful life, as follows: Number of years Buildings 50 Assets of the gas transmission system 20 Other fixed assets 4 - 20 Before 31 December 2008, costs of indebtedness were incurred as they occurred. As of 1 January 2009, costs of indebtedness attributable directly to the acquisition, construction or production of an asset with a long production cycle are capitalized as part of the cost of the respective asset. Costs of indebtedness attributable directly to the acquisition, construction or production of a long lead asset are those costs of indebtedness that would have been avoided if expenses with the asset hadn't been made. To the extent that funds are borrowed specifically for obtaining a long-lead asset, the borrowing costs eligible for the capitalization of the respective asset is determined by the actual cost generated by that borrowing during the period, minus the revenue from the temporary investments of those borrowings. To the extent that funds are generally borrowed and used for the purpose of obtaining a qualifying asset, the amount of borrowing costs eligible for capitalization is determined by applying a capitalization rate to the expenditures on that asset. The capitalization rate is the weighted average of the borrowing costs applicable to the borrowings of the entity that are outstanding during the period, other than borrowings made specifically for obtaining the long-lead asset. The costs of the funds borrowed for obtaining a long lead asset (achievement of the investment) are capitalized by the company on the asset as a difference between the current leverage costs related to such loan during the period and any revenue from the investments obtained from the temporary investment of these loans. Borrowing costs attributable to the arrangement are recognized as an expense in the period in which they are incurred, unless the operator has the contractual right to receive an intangible asset, in which case the borrowing costs attributable to an arrangement are capitalized during the engagement stage.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) The residual values of the assets and their useful lives are reviewed and adjusted as appropriate, at the end of each reporting period. The book value of the asset is written down immediately to its recoverable amount if the book value of the respective asset is greater than its estimated recoverable amount (Note 3.7). Gain and loss on disposal are determined by comparing amounts to be received with the book value and are recognized in the statement of comprehensive income in the period in which the sale took place. 3.7. Impairment of non-financial assets Depreciated assets are reviewed for impairment loss whenever events or changes in circumstances indicate that the book value may not be recoverable. The impairment loss is the difference between the book value and the recoverable amount of the asset. The recoverable amount is the greater of the asset's fair value minus costs to sell and value in use. An impairment loss recognized for an asset in prior periods is reversed if there are changes in the estimates used to determine the recoverable amount of the asset at the date the last impairment loss was recognized. For the calculation of this impairment, assets are grouped at the lowest levels for which there are identifiable independent cash flows (cash generating units). Depreciated non-financial assets are reviewed for possible reversal of the impairment at each reporting date. 3.8 Assets of public domain In accordance with Public Domain Law No. 213/1998, pipelines for gas transmission are public property. Government Decision 491/1998, confirmed by Government Decision 334/2000, states that fixed assets with a gross historical statutory book value of lei 474.952.575 (31 December 2017: RON 474.952.575), representing gas pipelines, are managed by the company. Therefore, the company has the exclusive right to use such assets during the concession and shall return them to the state at the end of this period (see Note 8). The company receives most of the benefits associated with the assets and is exposed to most of the risks, including the obligation to maintain network assets over a period at least equal to the remaining useful life, and the financial performance of the company is directly influenced by the state of the network. Therefore, before 1 January 2010, the company recognized those assets as tangible assets, with a proper reserve in the shareholders' equity (see Note 5.2.). Accounting policies applied to these assets were the same as those applied to the company's tangible assets (Notes 3.7 and 3.6). The company adopted IFRIC 12 as of 1 January 2010 and reclassified these assets and the subsequent improvements as intangible assets (except for international transmission pipelines).

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Starting with 01.01.2018, IFRS 15 `Revenues from the contracts with the clients` became applicable in Romania. This standard replaces a set of older standards (such as IAS 11, IAS 18) and changes IFRIC 12 giving a new interpretation to the contract notion. Therefore, our company registered the discounted receivables related to the regulated value remained undepreciated at the end of the concession agreement as a counterperformace and an intangible asset at a value diminished with the amount of the discounted receivables. In accordance with Public Concession Law No. 238/2004, a royalty is due for public goods managed by companies other than state-owned. The royalty rate for using the gas transmission pipelines is set by the government. As of October 2007, the royalty was set at 10% of the revenue. The duration of the concession agreement is 30 years, until 2032. Subsequent to the entry into force of the provisions of Art. 103 (2) of Law no. 123/2012 as of 12 November 2020, the royalty was set at 0,4%, from the domestic and international gas transmission services provided by the company. 3.9 Financial assets The company classifies its financial assets into the following categories: measured at fair value through profit or loss, measured at depreciated cost and measured at fair value by other elements of the comprehensive income. Classification is made depending on the purpose for which the financial assets were acquired. The management sets the classification of these fixed assets upon initial recognition. (a) Loans and receivables Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not listed in an active market. They are included in the current assets, except for those which have a maturity greater than 12 months after the end of the reporting period. These are classified as fixed assets. Loans and receivables of the company include `trade receivables and other receivables` and cash and cash equivalent in the statement of the financial position (Notes 3.11 and 3.13). Law 127/2014 entered into force on 5 October 2014 states that if the concession contract is terminated for any reason, or upon contract termination, the investment made by the national transmission system operator shall be transferred to the national transmission system owner or another grantor on payment of compensation equal to the regulated value which was not depreciated fixed by ANRE. The company recognized for the investments made until the balance sheet date an updated receivable related to the regulated value remained undepreciated at the end of the concession agreement, at a counterperformance and an intangible asset at a value less the updated receivable. The discount rate used to calculate the present value of the debt is long-term government bonds, zero coupon, over a period close to the remainder of the concession agreement. The initial measurement of the compensation is made at the fair value which reflects the credit risk which applies to the regulated amount remaining unamortized at the end of the contract. Subsequent valuation is done at amortized cost using the effective interest method. The actual interest rate used is based on historical data and does not change according to market interest rate.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) In 2019, ANRE Order no. 41/2019 on the adjustment of asset regulated value to the inflation rate. The company records the present value of the contractual cash flows recalculated as a result of the adjustment of the regulated asset value to the inflation rate and recognizes a gain or loss from the change in the profit or loss account. (b) Financial assets measured at fair value through the profit or loss account or measured at fair value by other elements of the comprehensive income IFRS 9 introduces a new approach to the classification of financial assets and comprises three main categories of financial assets: measured at amortized cost, at fair value through other comprehensive income, at fair value through profit or loss. The classification on IFRS 9 is determined by the cash flow characteristics and the business model in which an asset is held. This unitary approach based on principles eliminates the classification of financial assets in IAS 39: held-to-maturity investments, loans and receivables, and available for sale financial assets. The new model will also determine the existence of a single depreciation model applicable to all financial instruments. Upon initial recognition, an entity may make an irrevocable choice to present to other comprehensive income elements the subsequent changes in the fair value of an investment in an equity instrument that is neither held for trading nor is it a recognized contingent consideration by an acquirer in a business combination to which IFRS 3 applies. In this case it will recognize the dividends from that investment in the income statement. (c) Impairment of financial assets At each reporting date, the company assesses whether there is objective evidence that a financial asset or group of financial assets suffered impairment. A financial asset or group of financial assets is impaired and impairment loss is incurred if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset (a `loss generating event`) and if such event (or events) which generates loss has (have) an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated. The criteria that the company uses to determine that there is objective evidence of an impairment loss include:  significant financial difficulty of the issuer or debtor;  breach of contract, such as default or delinquency in interest or loan payment;  the company, for economic or legal reasons relating to the borrower's financial difficulty, grants to the borrower a concession that the lender would not otherwise have had in view;

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  it is likely that the debtor will go bankrupt or enter another form of financial reorganization;  disappearance of the active market for that financial asset because of financial difficulties; or  observable data indicate that there is a measurable decrease in the estimated future cash flows from a portfolio of financial assets since the initial recognition of those assets, although the decrease cannot yet be identified for individual financial assets in the portfolio, including:  adverse changes in the payment status of debtors in the portfolio; and  economic conditions, at national or local level, that correlate with defaults, relating to the assets in the portfolio. The company assesses first whether objective evidence of impairment exists. (i) Assets registered at amortized cost Impairment testing of trade receivables is described above. For loans and receivables, the amount of the loss is measured as the difference between the book value of the asset and the updated value of estimated future cash flows (excluding future credit loss which was not incurred), discounted at the asset's original rate; the discount rate for measuring any impairment loss is the current effective interest rate determined under the contract. In practice, the company may measure impairment based on the fair value of an instrument using an observable market price. If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be objectively related to an event occurring after the impairment was recognized (such as an improvement in the credit rating of the borrower), the reconsidered of impairment loss recognized previously in profit or loss. (ii) Assets measured at cost The share held at Eurotrangaz SRL is recognized at its fair value as of the date of trading, being evaluated, after the initial recognition, at cost according to Art.4.1.2 of IFRS 9 and Art.10.a-IAS 27- Separate Financial Statements: `When an entity prepares separate financial statements, it shall account for investments in subsidiaries, joint ventures and associates either at cost, in accordance with IFRS 9 or using the equity method.` In 2020 the company evaluated the stake held in Eurotrangaz SRL in order to identify any possible impairment losses. No impairments were found.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) 3.10. Inventories Inventories are stated at the lower of cost and net achievable value. The components recovered from disassemblings and repairs of pipelines built by the company are recorded as stocks at a value determined by a technical committee. The amount so determined does not exceed the net achievable value. The cost is determined based on the first in, first out method. Where necessary, adjustment is made for obsolete and slow moving inventories. Individually identified obsolete inventories are adjusted for the full value or written off. For slow moving inventory, an estimate is made of the age of each main category on inventory rotation. The calculation of the general adjustment for the depreciation of stocks is made monthly depending on the age of the existing items in stock, applying the following percentages according to age: 0 - 12 months 0%; 1 - 2 years 10%; 2 - 3 years 30% - 40%; over 3 years 75% - 80%. The cost of natural gas used for the balancing activity related to the transmission system is determined based on the average weighted cost method. The minimum gas stock that the company, as holder of the national natural gas transmission system operating license is required to have in underground storage facilities, is established by decision of the President of the National Energy Regulatory Authority (ANRE President). The Decision no. 588/08.04.2020 of the ANRE President established the obligation for the company to have a minimum level of natural gas stock of 560.724,517 MWh as at 31 October 2020, and the Decision no. 748/14.04.2021 of the ANRE President established the obligation for the company to have a level of natural gas stock of 597.115,143 MWh as at 31 October 2021. The debt adjustment policy according to IFRS9 is presented in note 12. 3.11. Trade receivables Trade receivables are amounts due from customers for services rendered in the ordinary course of business. If the collection period is one year or less (or in the normal operating cycle of the business), they are classified as current assets. If not, they are presented as fixed assets. Trade receivables are initially recognized at fair value and subsequently measured at amortized cost using the effective interest method, minus the adjustments for impairment.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) 3.12. Value Added Tax The value added tax must be paid to tax authorities based on the monthly VAT declaration by the 25th of the following month, regardless of the collection of receivables from customers. Tax authorities allow the settlement of VAT on a net basis. If the deductible VAT is higher than the output VAT, the difference is refundable at the request of the company. That VAT can be refunded after a tax audit, or, even in its absence, if certain conditions are met. VAT on sales and purchases which are not settled at the end of the reporting period is recognized in the statement of financial position at net value and disclosed separately as a current asset or liability. In cases where adjustments were made for impairment of receivables, impairment loss is recorded for the gross amount of the debtor, including the VAT. The related VAT has to be paid to the State and can be recovered, as from the date of the judgment or, as the case may be, the date of the closure of the bankruptcy, according to the insolvency law. 3.13. Cash and cash equivalent Cash and cash equivalents comprise cash on hand, cash in current accounts with banks, other short- term investments with high liquidity and with maturity terms of up to three months and overdrafts from banks. In the statement of financial position, overdraft facilities are registered at loans, under current liabilities. 3.14 Equity Share capital Ordinary shares are classified as equity. Additional costs directly attributable to the issue of new shares or options are registered at equity as a deduction, net of tax, from the receipts. Dividends Dividends are recognized as liabilities and deducted from equity at the end of the reporting period if they are declared before or at the end of the reporting period. Dividends are recognized when they are proposed before the end of the reporting period, or when they were proposed or declared after the end of the reporting period but before the date the financial statements were approved for issue. 3.15 Borrowings Borrowings are recognized initially at fair value, net of transaction costs recorded. Subsequently, borrowings are stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in profit or loss during the borrowings, based on the effective interest method. Borrowings are classified as current liabilities, unless the company has an unconditional right to defer payment of debt for no less than 12 months after the end of the reporting period.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) 3.16 Current and deferred profit tax Tax expense for the period includes the current tax and the deferred tax and is recognized in profit or loss, unless it is recognized in other items of the comprehensive income or directly in equity because it relates to transactions that are, in turn, recognized in the same or in a different period, in other items of the comprehensive income or directly in equity. Current profit tax expense is calculated based on the tax regulations in force at the end of the reporting period. The company periodically evaluates situations where the applicable tax regulations are subject to interpretation and establishes provisions/ adjustments for impairment, where appropriate, for the amounts with accounting/fiscal impact. The deferred profit tax is recognized based on the liability method, on temporary differences arising between the tax bases of assets and liabilities and their book values in the financial statements. However, the deferred profit tax arising from the initial recognition of an asset or liability in a transaction other than a business combination and at the time of the transaction does not affect the accounting profit and the taxable revenue is not recognized. The deferred profit tax is determined based on tax rates (and legal regulations) in force until the end of the reporting period and which are expected to apply in the period in which the deferred profit tax asset is realized or the deferred profit tax liability is settled. Deferred revenue tax assets are recognized to the extent that it is probable that future taxable profit be derived from temporary differences. 3.17 Commercial payables and other payables Suppliers and other payables are recognized initially at fair value and subsequently measured at amortized cost, using the effective interest method. Commercial payable accounts and other payables are closed as a result of the payment of debts, offsetting with receivables or their write-off through the profit and loss account. 3.18 Deferred revenue Deferred revenue is recorded for connection fees applied to customers upon their connection to the gas transmission network, for the objectives received free of charge and for grants collected. The grants collected are assimilated to the governmental subsidies. The governmental subsidies are acknowledged to their market value when there is a reasonable assurance that they will be received and that the relevant conditions will be met. For the connection fees applied to the clients for their connection to the gas transmission network and to the facilities received free of charge, for the grants the company chose to record the total asset value and a deferred revenue.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Law 127/2014 entered into force on 5 October 2014 states that if the concession contract is terminated for any reason, or upon contract termination, the investment made by the national transmission system operator shall be transferred to the national transmission system owner or another grantor on payment of compensation equal to the regulated value which was not depreciated fixed by ANRE. The company recognized for the investments made until the balance sheet date an updated receivable related to the remaining unamortised value at the end of the concession agreement at a counterperformance and an intangible asset at a value less the updated receivable. 3.19 Employee benefits In the normal course of business, the company makes payments to the Romanian state on behalf of its employees, for health funds, pensions and unemployment benefits. All the company employees are members of the pension plan of the Romanian state, which is a fixed contribution plan. These costs are recognized in the profit and loss account with the recognition of salary expenses. Benefits granted on retirement Under the collective agreement, the company must pay the employees on retirement a compensatory amount equal to a certain number of gross salaries, depending on the time worked in the gas industry, working conditions etc. The company recorded a provision for such payments (see Note 21). The obligation recognized in the balance sheet represents the present value of the obligation at the balance sheet date. The obligation is calculated annually by independent experts using the Projected Unit Credit Method. The present value is determined by discounting future cash flows with the interest rate of the long-term government bonds. The current service cost is recognized in the profit and loss account in the employee costs. Interest expense is included in the profit and loss account in the financial costs. Actuarial gain or loss due to changes in actuarial assumptions is recognized in the statement of comprehensive income in the period for which the actuarial calculation is made. Social insurance The company records expenses related to its employees, as a result of granting social insurance benefits. These amounts mainly include the implicit costs of employing workers and, therefore, are included in the salary expenses. Profit sharing and bonuses The company recognizes an obligation and expense for bonuses and profit sharing, based on a formula taking into account the profit attributable to the company's shareholders, after certain adjustments. The company recognizes an obligation where it is required under contract or where there is a past practice which created an implicit obligation.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) 3.20 Provisions for risks and charges The provisions for risks and charges are recognized when the company has a legal or implicit obligation as a result of past events, when for the settlement of the obligation an outflow of resources is required, which incorporates economic benefits and for which a credible estimate can be made in terms of the obligation value. Where there are similar obligations, the probability for an outflow of resources to be necessary for settlement is set after the assessment of the obligation class as a whole. The provision is recognized even if the probability of an outflow of resources related to any item included in any obligation class is reduced. Where the company expects the writing back to revenue of a provision, for example under an insurance contract, the reimbursement is recognized as a separate asset, but only when the reimbursement is theoretically certain. Provisions are measured at the discounted value of the expenditures expected to be required to settle the obligation, using a pre-tax rate that reflects the current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision due to passage of time is recognized as interest expense. 3.21 Revenue recognition Revenue covers the fair value of amounts received or receivable from the sale of services and/or goods in the normal course of business of the company. Revenue is recorded net of value added tax, returns, rebates and discounts. The company recognizes the revenue when their amount can be estimated with certainty, when it is probable that the entity collects future economic benefits and when certain criteria are met for each of the company's activities as described below. The amount of revenue is not considered reliably estimated until all contingencies relating to the sale are settled. The company bases its estimates on historical results, taking into account the type of customer, type of transaction and the specifics of each commitment. a) Revenue from services Revenue from the domestic and international gas transmission results from the booking of transmission capacity and from the transmission through the NTS of the determined quantities of natural gas, expressed in units of energy, during the validity of a gas transmission contract, and are recognized at the moment of their delivery. During the administration of the transmission contracts, the TSO issues and submits to the NU, by day 15 of the month following the month for which the transmission service was provided: an invoice for the transmission services provided for the previous month, based on the final allocations; an invoice related to the final daily imbalances registered in the previous month; and an invoice exceeding of the capacity booked.

SUMMARY OF THE SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Revenue from international transmission and similar activities are represented by the transmission capacity booking on the Isaccea 2.3 - Negru Voda 2.3 international transmission pipelines and by the amounts receivable for the reporting period under the Termination Agreement of the legacy contract between SNTGN Transgaz SA and GPE concluded for the transmission of natural gas through the T3 transit pipeline on Romanian territory to third countries. According to the Agreement for the termination of the legacy Contract between SNTGN Transgaz SA and GPE, the payment of the remaining amounts to be paid will be made in instalments over a maximum period of three years and the revenues received from transmission are regulated according to ANRE Order 41/2019 and ANRE Order 34/2014 respectively depending on the points where capacity is booked, the monthly difference being classified as assimilated revenues. According to the Network Code, the gas delivery day is defined as the time period beginning at 7:00 a.m. Romanian local time on any day and ending at 7:00 a.m. Romanian local time on the following day. The gas day shall be reduced to 23 hours at the changeover to daylight saving time and increased to 25 hours at the changeover to winter time, so that all related rights and obligations under the gas transmission contracts shall be increased or reduced accordingly on those gas days b) Revenue from the sale of goods Revenue from the sale of goods is registered when the goods are delivered. c) Interest revenue Interest revenue is recognized proportionally, based on the effective interest method. d) Revenue from dividends Dividends are recognized when the right to receive payment is recognized. e) Mutual compensation and barter transactions A relatively reduced part of the sales and purchases are compensated by mutual agreements, barter or non-cash agreements. These transactions generally occur in the form of cancellation of balances, either bilaterally or through a chain involving several companies (see Note 28). Sales and purchases that are intended to be offset by mutual agreements, barter or non-cash agreements are recognized based on management's estimates of their fair value to be received or disposed of in non-cash compensation. Fair value is determined based on the available market information. Non-cash transactions were excluded from the cash flow statement, so investing activities, financing activities, and all operational activities represent current cash flows. No barter transactions were performed in 2020 and in 2019. f) Revenue from penalties Revenue from penalties for late payment is recognized when future economic benefits are expected for the company.

FINANCIAL RISK MANAGEMENT Financial risk factors By the nature of the activities performed, the company is exposed to various risks, which include: market risk (including currency risk, interest rate risk on fair value, interest rate risk on cash flow and price risk), credit risk and liquidity risk. company's risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the financial performance of the company. The company does not use derivative financial instruments to protect itself from certain risk exposures. (a) Market risk (i) Currency risk The company is exposed to currency risk by exposures to various foreign currencies, especially to EUR. Currency risk is associated to assets (Note 12) and recognized liabilities. The company does not perform formal actions to minimize the currency risk related to its operations; therefore the company does not apply hedge accounting. However, the management believes that the company is covered in terms of the currency risk, given that the foreign currency incoming payments (mainly revenue from international transmission) are used to settle liabilities denominated in foreign currency. The following table shows the sensitivity of profit or loss and equity, to reasonably possible changes in exchange rates applied at the end of the reporting period of the functional currency of the company, with all variables held constant: 31 December 2021 31 December 2020 Impact on profit and loss and on equity of: USD appreciation by 10% 130.464 123.351 USD depreciation by 10% (130.464) (123.351) EUR appreciation by 10% (45.921.358) (35.954.181) EUR depreciation by 10% 45.921.358 35.954.181 (ii) Price risk The company is exposed to the commodity price risk related to gas purchased for own consumption. If the gas price had been 5% higher/lower, the net profit related to the period would have been lower/higher by lei 3.040.424 (December 2020: lei 3.325.834).

FINANCIAL RISK MANAGEMENT (CONTINUED) (iii) Interest rate risk on cash flow and fair value The company is exposed to interest rate risk by its bank deposits and variable interest loans. The company did not conclude any commitment to diminish the risk. For the average exposure of the period , if the interest rates had been lower/higher by 50 basis points, with all the other variables maintained constant, the profit related to the period and equity would have been lower/higher by 7.912.653 (December 2020: lower/higher by lei 7.705.629) as a result of reducing the interest rate for variable interest loans and the interest rate on the bank deposits. (b) Credit risk Credit risk is especially related to cash and cash equivalents and trade receivables. The company drew up a number of policies, through their application ensuring that sales of products and services are made to proper customers. The book value of receivables, net of adjustments for doubtful debts, represents the maximum value exposed to credit risk. The company's credit risk is concentrated on the 5 main customers, which together account for 45% of the trade receivable balances on 31 December 2021 (31 December 2020: 47%). Although the collection of receivables can be influenced by economic factors, the management believes that there is no significant risk of loss exceeding the adjustments already made. On 31 December 2021 the company has available payment guarantees from its clients amounting to lei 222.103.520. Cash is placed with financial institutions, which are considered as associated to a minimum performance risk. 31 December 2021 31 December 2020 Whithout rating 331.743 1.565.253 BB+ 168.203.478 129.228.022 BBB- 1.250.380 71.152.016 BBB 9.243 119.791 BBB+ 244.753.841 86.472.555 A - 136.721 A+ 136.085 - AA 112.021 643.159 414.796.791 289.317.517 All the financial institutions are presented in the Fitch rating or equivalent.

FINANCIAL RISK MANAGEMENT (CONTINUED) (c) Liquidity risk Preventive liquidity risk management involves keeping enough cash and funds available by a proper value of committed credit facilities. The company projects cash flows. The financial function of the company continually monitors the company's liquidity requirements to ensure that there is sufficient cash to meet operational requirements, while maintaining a sufficient level of unused borrowing facilities (Note 16) at any time, so the company does not violate the limits or loan agreements (where applicable) for any of its borrowing facilities. These projections take into account the company's debt financing plans, compliance with agreements, compliance with internal targets on the balance sheet indicators and, where appropriate, external regulations or legal provisions. The Financial Division of the company invests extra cash in interest bearing current accounts and term deposits, choosing instruments with appropriate maturities or sufficient liquidity to provide the appropriate framework, established under the provisions mentioned above. The table below shows obligations on 31 December 2021 in terms of contractual maturity remained. The amounts disclosed in the maturity table are contractual undiscounted cash flows. Maturity analysis of financial liabilities on 31 December 2021 is as follows: Total amount Less than 1 year 1-5 years Over 5 years Loans 2.278.593.629 171.952.005 984.570.956 1.122.070.668 Commercial payables and other payables 588.649.616 571.950.291 16.699.325 - 2.867.243.245 743.902,296 1.001.270.281 1.122.070.668 Maturity analysis of financial liabilities on 31 December 2020 is as follows: Total amount Less than 1 year 1-5 years over 5 years Loans 1.903.768.715 104.075.855 829.686.798 970.006.062 Commercial payables and other payables 450.599.080 434.116.640 16.482.440 - 2.354.367.795 538.192.495 846.169.238 970.006.062 Commercial payables and other payables include trade payables, suppliers of fixed assets, dividends payable, payables and other payables (see Note 19) and are not included: payables generated as a result of the legal provisions imposed by the authorities, payables to the employees and advance registered revenue.

Capital risk management The company's objectives related to capital management refer to keeping the company's capacity to continue its activity to provide compensation to shareholders and benefits to the other stakeholders and to maintain an optimal structure of the capital, as to reduce capital expenditure. There are no capital requirements imposed from outside. As for the other companies in this sector, the company monitors the capital based on the indebtedness degree. This coefficient is calculated as net debt divided by total capital. The net debt is calculated as total borrowings (including `current and long-term borrowings`, according to the statement of financial position), except for cash and cash equivalent. The total capital is calculated as `equity`, according to the statement of the financial position, plus the net debt.

FINANCIAL RISK MANAGEMENT (CONTINUED) In 2021 the company's strategy, unchanged since 2020, is to keep the indebtedness degree as low as possible, to keep a significant capacity to borrow funds for future investments. The net indebtedness degree on 31 December 2021 and on 31 December 2020 is reflected in the table below: 31 December 2021 31 December 2020 Total borrowings 2.031.297.592 1.714.795.911 Except: cash and cash equivalents (Note 13) (414.955.056) (289.452.040) Net cash position 1.616.342.536 1.425.343.871 Fair value estimate The fair value of the financial instruments traded on an active market is based on market prices quoted at the end of the reporting period. The fair value of the financial instruments that are not traded on an active market is set using valuation techniques. It is considered that the book value less the impairment adjustment of trade receivables and payables approximate their fair values. The fair value of financial liabilities is estimated by discounting the future contractual cash flows using the current market interest rate available to the company for similar financial instruments. 5. SIGNIFICANT ACCOUNTING JUDGEMENTS AND ESTIMATES IN APPLYING ACCOUNTING POLICIES Critical accounting estimates and assumptions The company develops estimates and assumptions concerning the future. Estimates and assumptions are continuously evaluated and are based on historical experience and other factors, including predictions of future events considered reasonable under certain circumstances. The resulting accounting estimates will, by definition, seldom equal the actual results. Estimates and assumptions that have a significant risk of causing an important material adjustment to the book value of assets and liabilities within the next financial year are presented below.

SIGNIFICANT ACCOUNTING JUDGEMENTS AND ESTIMATES IN APPLYING ACCOUNTING POLICIES (CONTINUED) 5.1 Assumptions for the determination of the provision for retirement benefits This provision was calculated based on estimates of the average wage, the average number of employees and the average number of wage payment at retirement, as well as based on the benefits payment scheme. The provision was brought to the present value by applying a discount factor calculated based on the risk-free interest rate (i.e. interest rate on government bonds). The present value of the obligations at 31 December 2021 is of lei 110.048.408 (on 31 December 2020 121.509.097) (Note 21). 31 December 2021 31 December 2020 Inflation rate +1% 123.853.864 137.780.682 Inflation rate -1% 98.056.517 107.470.989 Investment return +10% 104.052.637 117.004.460 Investment return -10% 116.610.244 126.343.862 Analysis of the maturity of benefits payments: 31 December 2021 31 December 2020 Up to one year 4.592.018 3.198.877 Between 1 and 2 years 2.785.733 2.376.495 Between 2 and 5 years 10.993.273 9.156.180 Between 5 and 10 years 72.309.686 63.538.232 5.2 The accounting treatment of the concession agreement As indicated in Note 8, in May 2002 the company concluded a Concession Agreement with the National Agency for Mineral Resources (`ANRM`), which entitles the company to use the main pipelines of the national gas transmission system for a period of 30 years. Before concluding this agreement, the pipelines were managed by the company according to Public Domain Law No. 213/1998, Government Decision (`GD`) No. 491/1998 and GD No. 334 of 2000 by which the company was established. According to the provisions of this agreement, the company receives most of benefits associated to assets and is exposed to most of the risks. Therefore, the company recognized these assets in the statement of the financial position, with an appropriate reserve in equity.

SIGNIFICANT ACCOUNTING JUDGEMENTS AND ESTIMATES IN APPLYING ACCOUNTING POLICIES (CONTINUED) Regarding the already existing infrastructure on the date of signing the Concession Agreement, given that the company has no payment obligations at the time of terminating the Concession Agreement (but only obligations on maintenance and modernization, investments in new pipelines), the company's management considered that it is, in substance, an equity component, defined as the residual interest in the company's assets after the deduction of all debts. In addition, because the company and its predecessor, SNGN Romgaz SA, were controlled by the Romanian state, the publication of Public Patrimony Law (i.e. loss of property) and the reorganization of SNGN Romgaz SA into 5 companies can be treated as transactions with shareholders, in its capacity of shareholder, which supports the recognition of transactions in equity. As of 2010, the company applied IFRIC 12 (Note 3.5). 5.3 The accounting treatment of royalties payable for using the national gas transmission system As indicated in Note 8, the company pays royalties, calculated as percentage of the gross revenue achieved from the operation of pipelines of the national gas transmission system. These costs were recognized as expenses, rather than deduction from revenue, because they are not of the nature of taxes collected from customers and sent to the state, given the nature of activity and the regulatory framework: - the company's revenue is based on tariffs approved by another regulator than the one setting the level of royalties; - expense with royalties is an item taken into consideration at the calculation of the transmission tariff; As of 1 January 2020, according to ANRE Order no. 1/2020, the company has the obligation to pay annually to ANRE a tariff amounting to 0,062 lei MWh applied to the quantity of natural gas transmitted for carrying out activities in the natural gas sector based on a license. 5.4 Long-term receivables Law 127/2014 entered into force on 5 October 2014 states that if the concession contract is terminated for any reason, or upon contract termination, the investment made by the national transmission system operator shall be transferred to the national transmission system owner or another grantor in exchange for the payment of a compensation equal to the unamortized regulated value set by ANRE. The company believes that the legislative change represents a compensation for the value of the investments made, which the company will not recover through the tariff, implicitly the value of the intangible asset not recovered through the tariff, recognized for the right to charge users.

SIGNIFICANT ACCOUNTING JUDGEMENTS AND ESTIMATES IN APPLYING ACCOUNTING POLICIES (CONTINUED) From 01.01.2018, IFRS 15 Revenue from Contracts with Customers became applicable in Romania. This standard replaces some older standards (such as IAS 11, IAS 18) and amends IFRIC 12 by introducing new interpretations to the notion of a contract. As a result, the company applies the bifurcated model registering the updated receivable related to the regulated amount remaining unamortized at the end of the concession agreement as a financial asset the intangible asset will be presented in the financial statements by the residual method resulted less the value of the construction works, achieved at fair value with the amount of the updated long term receivable (compensation) upon the commissioning of the investment. The present value was determined for the remaining period of the concession contract (the year 2032), because it is estimated that it will not be terminated before the expiration date (see Note 3.9 (a)). In 2019 ANRE Order n0. 41/2019 on the adjustment of the regulated value of the assets at the inflation rate entered into force. The company records the present value of the contractual cashflows recalculated as a result of the adjustment of the regulated asset value to the inflation rate and recognizes a gain or loss from the change in the profit or loss account. From 2021 onwards, the company has changed the way of estimating the discount rate for the present value calculation, using instead of the Bloomberg rate the NBR reference rate for government securities (fixing), considering that this rate reflects with increased fidelity the internal context in which the transactions take place; by using a rate fixed for a period of 10 years, there is no need for a sensitivity analysis associated with this calculation. Reporting segments are set according to the nature of the activities conducted by the company: the regulated activity, the unregulated activity and other activities. As transmission system operator, the company reported annually to the National Regulatory Authority on the activity performed on the four reporting segments.

TANGIBLE ASSETS (CONTINUED) Regarding the assets developed by the company, which are complementary to the provision of services according to the concession agreement, the State has the option to acquire these assets at the end of the concession agreement. The company does not have the obligation to keep these assets until the end of the concession agreement and it is allowed to sell them. These assets do not fall within the scope of IFRIC 12. All the other assets related to the domestic transmission activity and which are part of the national gas transmission system, including improvements made after signing the concession agreement and which must be handed over to the ANRM at the end of the concession agreement fall within the scope of IFRIC 12. In 2021 the assets used for the provision of the international transmission services through the Isaccea 2 - Negru Vodă 2 and Isaccea 3 – Negru Vodă 3 pipelines do not fall within the scope of IFRIC 12. The company does not depreciate the tangible assets approved for discarding and does not own pledged fixed assets. 8. SERVICE CONCESSION AGREEMENT In May 2002, the company concluded a Service Concession Agreement (`SCA`) with the ANRM, which entitles the company to operate the main pipelines of the national gas transmission system for a period of 30 years. Before concluding this agreement, the pipelines were managed by the company according to Public Domain Law No. 213/1998, GD No. 491/1998 and GD No. 334/2000 by which the company was established. All modernizations and improvements made by the company to the system are considered part of the system and become property of the ANRM at the end of their useful life. The company cannot sell or discard any asset part of the national transmission system; withdrawals can only be made with the approval of the state. At the expiration of the agreement, the assets belonging to the public domain, existing upon signing the agreement and all investments made in the system will be returned to the State. The company owns and will develop other assets that are not directly part of the national gas transmission system, but are complementary assets for gas transmission operations. The ANRM has the option to buy these assets at the end of the concession agreement, at the fair value. The main terms of the Concession Agreement are the following:  The company is entitled to operate directly the assets subject to the concession agreement and to apply and collect tariffs for domestic and international transmission from clients in exchange for services provided; the company is the only entity authorized to operate the pipelines of the national gas transmission system, no sub-concession being allowed;

SERVICE CONCESSION AGREEMENT (CONTINUED)  Any change of tariffs must be proposed by the company and then approved by the ANRE;  The company is exempt from the payment of import duties for the assets acquired for operation, improvement or development of the system;  The company must annually publish by 30 October the available capacity of the system for the following year;  The company must annually respond to the clients' orders by 30 November and the ANRM must be informed on all rejected orders decided by the company's management;  The company must keep a specific level of functioning (guaranteed through a mandatory minimum investment programme);  royalties are paid as percentage (by 30 September 2007: 5%, as of October 2007: 10%) of the gross revenue from the operation of the national transmission system (domestic and international transmission);  all operating expenses for operating the system are incurred by the company;  The company may cancel the agreement by notifying the ANRM 12 months in advance;  The ANRM may cancel the agreement by a 6-month prior notice, if the company fails to comply with the contractual conditions; it also has the option to cancel the agreement with a 30-day prior notice for `national interest` reasons; in this case, the company will receive compensation equal to the average net profit of the past 5 years multiplied by the remaining duration of the agreement. The Concession Agreement does not include an automatic renewal clause. The terms of the Concession Agreement were not amended after June 2003, except for the approval of the minimum investment plans.

Resial SA went into liquidation in 2006; the procedure is carried out by a bailiff appointed by the court and is outside the control of the company, which is why the stake is not consolidated and is recorded at cost less the adjustment for impairment amounting to 100% of the cost. The loan granted to Resial SA is also fully adjusted. The management does not expect the company to recover any amount of this stake and the company does not guarantee any type of residual obligations for Resial SA. Shares in Mebis SA Shares owned in Mebis SA were obtained in February 2004, as a result of a procedure for the recovery of claims due from a client. Mebis SA is in the liquidation procedure, which is why the stake in Mebis SA was fully adjusted. The company has no obligations to Mebis SA. In case of the financial assets held by Transgaz, i.e. Mebis SA and Resial SA , the application of IFRS 9 has no impact whatsoever, as such assets are measured at the fair value by the profit and loss account and 100% impairment adjustments were established.

COMMERCIAL RECEIVABLES AND OTHER RECEIVABLES (CONTINUED) IFRS 9 introduces a new model for forecasting impairment loss based on the estimated loss. This model entails the anticipated recognition of the loss from receivables impairment. The standard provides for the fact that the entities register the anticipated loss by receivables impairment from the moment of the financial instrument initial recognition and recognize the anticipated loss from the impairment over their entire life. The value of the anticipated loss will be discounted for each reporting period so that it reflects the cred risk changes as opposed to the initial recognition. For the application of IFRS 9 on the held receivables, based on a loss estimation model, the clients categories were reconsidered starting from the IFRS 9 principle for the anticipation of a non-cashing in risk related to the current receivables. To estimate the trade receivables non-collection risk, a non-collection rate based on risk categories was applied as follows: - international transmission receivables - receivables with no risk of on-time collection ; - doubtful or contested other than affiliated parties receivables - receivables with high risk of non-collection that are subject to certain court actions. Impairment adjustments of 100% of the receivables amount are calculated; - affiliated parties receivables - risk-free receivables are provisioned by seniority instalments, i.e. within the range 31-60 a 10% percentage, 61-90 a 20% percentage, 91-120 a 30% percentage, 121-150 a 35%, 151-180 a 60%, and over 181 with a 100% percentage. Doubtful receivables subject to court actions are provisioned with up to 100% of the amount. A provision of 100% for receivables exceeding 30 days and of 5% for current receivables is made up for the receivables that are not subject to court actions and have a non-collection risk. - Various clients (other trade receivables and various clients receivables) - the risk-free receivables are provisioned by seniority instalments, 10% for the range 31-60 , 20% for the 61-90 , 30% for the range 91-120, 35% for the range 121-150, 60% for the range 151-180, and 100% for the receivables over 181. Doubtful receivables subject to court actions are provided with up to 100% of the amount. For receivables that are not subject to court actions and have a risk of non-collection, a provision of 100% for the receivables exceeding 30 days and 5% for the current receivables is made up.

PROVISION FOR EMPLOYEE BENEFITS Employee benefits According to the collective labour contract, the company must pay to employees upon retirement a compensatory amount equal to a certain number of salaries, calculated as the average of the monthly salary average achieved over the last 12 months, depending on the period of activity in the gas industry, working conditions etc. The present value of the provision was determined based on the Projected Unit Credit Method. Retirement benefits received by an employee were first raised by the contributions of the employer and then every benefit was updated taking into account the rotation of employees, layoffs and the probability of survival until retirement. The number of years until retirement was calculated as the difference between retirement age and age at time of reporting. The expected average of the remaining work period was calculated based on the number of years until retirement, also taking into account the rate of layoffs, employee rotation rate and the probability of survival. Assumptions 2021 The amount of the provision was calculated individually for each distinct employee/beneficiary of the company using the actuarial calculation method and taking into account International Accounting Standards, in particular the IAS 19. The provision is calculated taking into account the long-term liabilities undertaken by the company under the collective labour contract. The calculation assumptions and specifications for the calculation model were established based on the company's previous experience and a set of assumptions about the company's future experience. The most important actuarial assumptions used are as follows: - for the benefit consisting of basic salaries paid at retirement, this benefit is paid for company employees who reach retirement; - the dismissal rate is zero because there is no program for collective or individual dismissals; - the mortality of the entity's employees is calculated according to the data provided by the National Institute of Statistics for the years 2011 – 2020; - the employee turnover rate is is constant over time; - the method used is the projected credit factor method; - Retirement age at retirement considered: 65 for men and 63 for women. - Long-term wage growth rate considered equal to the forecast inflation rate for the euro area, and is 1,7%, and in the short term considered equal to the forecast inflation rate for RON and is 7,2% in the first year, 3,9% in the second year and 2,5% for the next 8 years for both women and men. - the plan is not financed by the entity and employees. - It has been estimated that people approaching retirement age are likely to retire early - For the death benefit, for retired former employees, in the case of death in the first year after retirement, mortality at the age of 66 men and 64 years women was used by simplification, analyzing the data for the periods 2018-2021.

SIGNIFICANT TRANSACTIONS NOT INVOLVING CASH Compensations Approximately 5,13 % of the receivables were settled by transactions that haven't involved cash outflows during the period ended 31 December 2021 (31 December 2020: 0,82%). Transactions mainly represent sales of products and services in exchange for raw materials and services or offsets with clients and suppliers within the operating cycle. Barter transactions No barter transactions were made in 2021 and in 2020. 30. CONTINGENCIES, COMMITMENTS AND OPERATIONAL RISKS i) Commitments The Service Concession Agreement (S.C.A. - Note 8) provides that, at the end of the agreement, ANRM is entitled to receive back, all public property goods existing when the agreement was signed and all investments made into the national transmission system, in accordance with the investment program stipulated in the service concession agreement. The company also has other obligations related to the concession agreement, which are described in Note 8. Law 127/2014 entered into force on 5 October 2014 states that if the concession contract is terminated for any reason, or upon contract termination, the investment made by the national transmission system operator shall be transferred to the national transmission system owner or to another grantor on payment of compensation equal to the unamotrized regulated value established by ANRE, as presented in Note 3.18. On 31 December 2021 the value of the parent company contractual firm obligations for the purchase of tangible and intangible assets is of lei 292.500.005, and the subsidiary Eurotransgaz SRL has no capital commitments. Eurotransgaz SRL, the company established and owned by Transgaz in Moldova, was appointed the winner of the privatization investment contest for the single patrimonial complex State Enterprise Vestmoldtransgaz operating the Iasi-Ungheni gas transmission pipeline on the territory of Moldova under the following conditions: payment of the sale price and making investments in the next two years for the construction of a gas transmission pipeline between Ungheni and Chisinau, as well as of the necessary equipment for the operation of this pipeline. The company is a guarantor of the loan agreement concluded on 24 January 2019 between the European Investment Bank and Eurotransgaz, in total amount of Euro 38 milion, for the funding of the construction by Vestmoldtransgaz of the Ungheni-Chisinau gas transmission pipeline.

CONTINGENCIES, COMMITMENTS AND OPERATIONAL RISKS (CONTINUED) On 11 December 2019 the European Bank for Reconstruction and Development approved Project 50410, which is capital investments as a capital increase in exchange for the participation in the share capital of Vestmoldtransgaz SRL, a subsidiary of Eurotrasngaz SRL, owned and controlled by the Romanian gas transmission operator SNTGN Transgaz SA. The investment of the bank will finance the construction of the Ungheni-Chisinau gas pipeline in Moldova, approximately 120 km and a planned capacity of 1,5 bcm. ii) Taxation The taxation system in Romania is in a phase of consolidation and harmonization with the European law. However, there are still various interpretations of the tax law. In Romania, the tax year remains open for fiscal verification for 5 years. The company's management believes that fiscal obligations included in these financial statements are properly presented and that it is not necessary for any additional provisions to be established to cover the uncertainties related to tax treatment. The rate of the royalty for the use of gas transmission pipelines in Romania is set by the government. As of October 2007, the royalty has been set at 10% of revenue. Subsequent to the entry into force of the provisions of Art. 103 (2) of Law no. 123/2012, starting with 12 November 2020 the royalty was set at 0.4% of the domestic and international gas transmission services provided by the company. ANRM requests Transgaz to calculate and pay the royalty by applying the percentage of 10% according to Law 238/2004 and the percentage of 0.4% according to Law 123/2012. The company considers that it has the obligation to calculate and pay a single royalty in the percentage of 0.4% established by the special law, that is Law 123/2012. The company is subject to a tax inspection of the royalty iii) Insurance policies The company does not have insurance policies related to operations, complaints on products, or for the public debt. The company has insurance policies for buildings and mandatory civil liability policies for the car fleet. Moreover, the company has contracted professional liability insurance services for the members of the Board of Administration and for 57 managers in 2021 (54 managers in 2020). iv) Environmental aspects Environmental regulations are under development in Romania and the company did not record any obligation on 31 December 2021 and 31 December 2020 related to anticipated expenses that include legal and consulting fees, analysis of locations, preparing and implementing recovery measures related to environmental protection. The management of the company believes there are no significant obligations related to environmental aspects.

CONTINGENCIES, COMMITMENTS AND OPERATIONAL RISKS (CONTINUED) v) Lawsuits and other actions During the company’s business as usual, there were complaints against it. The company has pending disputes for the lack of use of lands occupied with NTS objectives, commercial and labour disputes. Based on its own estimates and internal and external consulting, the company's management believes there will be no material loss exceeding the provisions established in these financial statements and is not aware of circumstances that give rise to potentially significant obligations in this regard. The company was the subject of an investigation by the Competition Council regarding the manner in which procedures were awarded for works contracts carried out by Transgaz during 2009-2011, before the implementation of private management according to the provisions of GEO 109/2011 on corporate governance of public enterprises. In 2020, the Competition Council communicated Decision no. 43 / 11.08.2020 sanctioning the Company with a fine in the amount of lei 34.166.616. The company challenged in court the decision of the Competition Council (Note 20). The court ordered the suspension of the contested administrative act, until the final settlement of the case. Control Y Montajes Industriales SA Within the statements of 31 December 2019, Vestmoldtransgaz is involved in a dispute with Control Y Montajes Industriales S.A. The dispute arose within the procurement procedure in connection with the disagreement of the participant Control Y Montajes Industriales S.A. regarding the manner in which the tender was conducted. In court, the plaintiff requests the annulment of the results of the procurement procedure invoking clauses of the regulation of the National Energy Regulatory Agency. The Vestmoldtransgaz’ winning likelihood is qualified as high. As of 6 June 2016, the company has been subject to an investigation carried out by the European Commission - Directorate General for Competition under Art. 20 (4) of Council Regulation (EC) No 1/2003 on the implementation of the rules on competition laid down in Articles 81 and 82 of the EC Treaty, which became Articles 101 and 102 of the Treaty on the Functioning of the European Union, namely: - to provide a minimum export capacity of 1.75 billion cubic meters per year at the interconnection point between Romania and Hungary (Csanádpalota); - to make available minimum export capacities of 3.7 billion cubic meters per year in total at two interconnection points between Romania and Bulgaria (Giurgiu / Ruse and Negru Vodă I / Kardam); - to make sure that the tariffs to be proposed to the Romanian Energy Regulatory Authority (ANRE) will not make any difference between the export and the domestic markets, thus avoiding interconnection tariffs that render exports commercially non-feasible; - refrain from using any other means of obstructing exports.

CONTINGENCIES, COMMITMENTS AND OPERATIONAL RISKS (CONTINUED) Based on their own estimates, the company's management considers that there are no circumstances that would give rise to significant potential liabilities in this regard. In 2020 an administrator initiated court proceedings to recover amounts of money representing unpaid difference, amounts they consider to be due as a result of the mandate contract carried out in 2015-2017. Based on its own estimates, the company considers that there are no circumstances that could lead to potential significant obligations in this respect. Following the conclusion of the arbitration proceedings with Bulgargaz EAD, the arbitral tribunal upheld Bulgargaz EAD's claim and ordered the restitution of the quantity of natural gas of 6,733,433 m3 and, if restitution in kind is not possible, the reimbursement of the monetary equivalent of the linepack, and statutory interest. The decision of the arbitral tribunal has been appealed and the action for annulment has been registered with the Bucharest Court of Appeal. The company had the quality of intervener in a dispute with the subject of the annulment of the ANRE decision of 2017 regarding the interpretation and application of the provisions of Art. 99 of the Network Code, respectively regarding the calculation of the invoices related to the exceeding of the capacity booked by the network users, in this case ENGIE Romania SA. By Civil Decision no. 3829/2021, the High Court of Cassation and Justice rejected as unfounded the request for annulment of Decision no. 2 of 31 May 2017 of the Commission for the settlement of disputes on the wholesale and retail market established within ANRE, formulated by the plaintiff Engie Romania in contradiction with ANRE and the forced intervener Transgaz. The decision is final. Moreover, the revenue being regulated, the diminished amount would have been the object of the recovery from the regulated revenue of the following gas year. In 2020, respectively in 2021, the network user filed several lawsuits in court, having as subject the recalculation of the tariff for the excess capacity booked for the time span November 2016 - February 2017, respectively March 2017-December 2017 and January-April 2018 and the payment of the amount of lei 57.444.164, 5.112.291,07 and respectively 17.789.789. Based on its own estimates, the Company's management considers that there are no circumstances that would give rise to obligations in this regard. vi) Government policies in the gas sector of Romania ANRE is an autonomous public institution and sets tariffs for the natural gas transmission activity charged by the company. It is likely that the Agency decides upon the implementation of changes of the government strategies in the gas sector, determining changes in the tariffs approved for the company and, thus, having a significant impact on the company's revenue. At the same time, the Romanian government could decide to change the royalty applied to the company for using the assets part of the public domain according to SCA. Currently, the effects of the future government policies related to the Romanian gas sector on the company's asset and liability, if any, cannot be determined.

CONTINGENCIES, COMMITMENTS AND OPERATIONAL RISKS (CONTINUED) There are various interpretations of the legislation in force. In certain situations, ANRE may treat differently certain aspects, proceeding to the calculation of additional tariffs and of delay penalties. The company's management believes that its obligations to ANRE are properly presented in these financial statements. vii) Commitments under the sale-purchase agreement between Vestmoldtransgaz and the European Investment Bank The deadline for completion of the Investment Plan according to the SE Vestmoldtransgaz sale-purchase agreement is 23 months from the date when all the necessary conditions for starting the construction of the Investment Plan (Ungheni - Chisinau gas pipeline) have been met, that is November 2021. The deadline for the execution of the Ungheni Chisinau gas pipeline project agreed by Eurotransgaz with the European Investment Bank is Q IV2021. viii) The impact of COVID-19 In the context of the COVID-19 pandemic, the company cooperates with the authorities and takes the necessary measures to ensure the provision of the gas transmission service in a safe manner and to ensure the safety of the personnel. The company prepared and published a plan of measures approved by the Board of Administration, which aims to minimize the effects of the epidemic on the health and safety of the employees and to ensure the continuity of the natural gas transmission service and the safety of the National Transmission System. The company provides a public service of national interest being included in the regulated segment of the internal gas market. The gas transmission activity is regulated by the National Energy Regulatory Authority. The company aims to achieve the indicators provided for in the Revenue and Expenditure Budget for 2020 and to provide the necessary financing sources for the development of the investment program whose execution rate could be influenced by the ability of the contracting companies to provide the equipment and personnel necessary to carry out the works in the context of the isolation or quarantine situations generated by COVID-19. The legislative changes adopted offer the possibility of small and medium-sized enterprises to delay the payment of utilities, which could have an indirect impact on the company's activity. Although there are still many uncertainties, at this moment we consider that the short-term impact of such legislative changes on the activity and recoverability of the assets of the company will not be significant. During the alert state, the transmission and distribution operators of electricity and natural gas ensure the continuity of service provision, and in the event that there is an incident of disconnection, they postpone the performance of such operation until the alert state ends.
