Goodwill from a business combination is initially measured at cost. This is calculated as the excess of the consideration transferred over the identifiable assets acquired and liabilities assumed. Subsequent to initial recognition, goodwill is measured at cost less accumulated impairment losses. Goodwill is not amortised, rather, it is subjected to annual impairment testing in accordance with IAS 36. The Group conducts its annual test for goodwill impairment at year’s end (31 December). Testing is also performed if events or circumstances indicate that the figure could be impaired. For the purpose of the impairment testing, goodwill is assigned to one or more of the Group’s cash-generating units that should benefit from the synergy effects of the combination. The recoverability of goodwill is determined by comparing the carrying amount of the respective cash-generating unit (CGU) or units with the recoverable amount. If the goodwill is impaired, an impairment loss is recognised. A reversal of impairment losses once the reasons for the impairment no longer apply is not foreseen for goodwill.

Other intangible assets

Acquired intangible assets are recognised at their initial costs less amortisation and impairment losses if applicable.

The subsequent measurement of intangible assets with definite useful lives is performed at cost less accumulated amortisation and impairment losses. Within the Group, there are no intangible assets with indefinite useful lives.

The following useful lives were assumed for intangible assets for amortisation using the straight-line method:

Government subsidies and investment grants are offset against the cost of the assets and amortised in proportion to their useful lives. A government grant is recognised when there is reasonable assurance that the grant will be received, and the Group complies with the necessary conditions for receiving the grant.

Assets that are subject to depreciation or amortisation, as well as other investments and associates, are tested for impairment whenever events or changes in circumstances indicate that their carrying amount may no longer be recoverable. Assets that have an indefinite useful life, such as goodwill or intangible assets not yet available for use, are tested for impairment annually as such assets are not subject to depreciation or amortisation.

To identify the need for an impairment loss, the recoverable amount is determined. The recoverable amount is the higher of fair value of the asset less costs to sell and value in use. If it is not possible to determine the recoverable amount for an individual asset, then the recoverable amount is determined for the smallest identifiable group of assets (cash-generating unit) to which the asset in question can be assigned.

Considering that, as a rule, market prices are not available for individual units, the present value of net cash inflows is used to determine the fair value less costs to sell. The forecast of the cash flows is based on STRABAG’s latest planning, with a planning horizon of at least four years. The last detailed planning year forms the basis for calculating the perpetuity if applicable legislation and legal requirements do not limit the usability of the cash-generating unit to a shorter period of time.

For the purpose of determining the fair value less costs to sell, the cash-generating unit is measured from the viewpoint of an independent market participant. In calculating the value in use of an asset, on the other hand, the cash flows are considered based on the previous use. For the net cash inflows beyond the detailed planning period, individual growth rates derived from market information are determined based on long-term business expectations in both methods of calculation.

Net cash inflows are discounted at the cost of capital, which is calculated as the weighted average cost of equity and debt. Consideration is given to the different yield and risk profiles of STRABAG’s various areas of expertise by determining the individual costs of capital using comparison companies. The cost of equity corresponds to the required rate of return for investors, while the cost of debt is based on the long-term financing conditions available to comparison companies. Both components are derived from capital market information.

The following table shows the parameters growth rate and cost of capital for impairment testing:

The Management Board has calculated the budgeted gross margin based on past developments and on expectations for future market development.

If the recoverable amount of an asset is lower than the carrying amount, an impairment loss is recognised immediately in profit or loss. In the case of impairment losses related to cash-generating units which contain goodwill, existing goodwill is initially reduced. If the impairment loss exceeds the carrying amount of the goodwill, the difference is generally apportioned proportionally over the remaining non-current assets of the cash-generating unit.

With the exception of goodwill, non-financial assets for which an impairment loss was charged in the past are reviewed at every balance sheet date to determine whether the impairment loss should be reversed.

Financial assets are recognised in the consolidated balance sheet if STRABAG has a contractual right to receive cash or other financial assets from another party. Regular way purchases and sales of financial assets are recognised using settlement date; the trade date is used for derivatives.

Financial assets that are not measured at fair value through profit or loss are initially recognised at fair value plus transaction costs which are directly attributable to the acquisition.

Transaction costs which arise upon the acquisition of financial assets measured at fair value through profit or loss are immediately recognised as an expense.

Receivables bearing no interest or interest below the market rate are initially recognised at the present value of the expected future cash flows.

For purposes of subsequent measurement, financial assets are classified in one of the following categories in accordance with IFRS 9, with each category having its own measurement requirements. The classification is determined at initial recognition.

For measurement and accounting purposes, financial assets are to be assigned to one of the following categories:

Trade receivables also include receivables from consortia.

Trade receivables and receivables from consortia are recognised in the consolidated balance sheet if STRABAG has a contractual right to receive cash or other financial assets from another party. Recognition is made on the settlement date.

Receivables bearing no interest or interest below the market rate are initially recognised at the present value of the expected future cash flows.

Subsequent measurement of trade receivables and receivables from consortia is at amortised cost less impairment losses for expected credit losses (see the section “Impairment of financial assets and contract assets”).

These are classified as current financial assets if they mature within twelve months after the reporting date or within the usual business cycle. Otherwise, they are classified as non-current financial assets.

A financial asset that is to be classified as a debt instrument under IAS 32 is measured at fair value through profit or loss if it is held for trading purposes, the cash flow criteria are not met, or it is designated as at FVPL at initial recognition. A financial asset at STRABAG is assigned to this category if it was principally acquired with an intention to sell in the short term. Derivatives also belong to this category if they do not qualify as hedging instruments. Assets in this category are recognised as current assets if the asset is expected to be realised within twelve months. All other assets are classified as non-current. Value changes of financial assets measured at fair value through profit or loss are recognised through profit or loss.

This category includes securities reported under non-current financial assets and securities reported under cash and cash equivalents.

The fair value option may be elected for financial assets which, based on the underlying business model and the contractual cash flows, are classified as measured at amortised cost if doing so eliminates or significantly reduces a measurement or recognition inconsistency. The fair value option is not elected at STRABAG.

Financial assets which represent equity instruments under IAS 32 are also measured at fair value through profit or loss. Value changes are recognised through profit or loss in the income statement.

This category contains mainly investments below 20% that are held under other investments.

Upon initial recognition of equity instruments measured at fair value, there exists an irrevocable option to recognise value changes in other comprehensive income rather than in the income statement, provided the equity instrument is not held for trading purposes. Equity investments recognised in the other comprehensive income may not be later reclassified to the income statement. The option is not exercised at STRABAG.

Financial assets and financial liabilities are offset and the net amount is presented in the balance sheet when there is a legally enforceable right to offset the recognised amounts and the settlement is on a net basis. This concerns, to a minor extent, the settlement of trade receivables and payables.

Deferred tax assets may only be recognised if the associated tax advantage is likely to be realisable. The calculation of the tax deferral is based on the usual income tax rate in the respective country at the point of the predicted reversal.

Recognition is made of deferred tax liabilities arising from temporary differences in relation to investments in subsidiaries, joint ventures and associates unless the timing of the reversal of the temporary differences in the Group can be determined and the temporary differences are unlikely to reverse in response to this influence in the foreseeable future.

The financial liabilities at STRABAG comprise non-derivative liabilities and derivatives with a negative fair value on the reporting date.

For accounting and measurement purposes, financial liabilities are to be assigned to one of the following categories:

Non-derivative financial liabilities are recognised in the consolidated balance sheet if STRABAG has a contractual obligation to transfer cash or other financial assets to another party. Initial recognition of non-derivative financial liabilities is made at fair value. Financial liabilities that are not measured at fair value through profit or loss are initially recognised at fair value including transaction costs, which are directly attributable to the acquisition.

A financial liability is classified as current provided the company does not have an unconditional right to defer settlement of the liability for at least twelve months after the reporting period.

During subsequent measurement of non-derivative financial liabilities carried at amortised cost, any premiums or discounts between the amount received and the repayment amount are spread over the financing term using the effective interest method and recognised in interest expense on an accrual basis.

A financial liability is only measured at fair value through profit or loss if it is held for trading purposes or designated as such at initial recognition. Derivatives with negative market value also belong to this category if they are not designated as hedging instruments.

Transaction costs which arise upon the acquisition of financial liabilities measured at fair value through profit or loss are immediately recognised as an expense.

The fair value option was not exercised for financial liabilities.

Trade payables also include payables from consortia. For accounting and measurement purposes, these are classified as financial liabilities measured at amortised cost.

Non-derivative financial liabilities are recognised in the consolidated balance sheet if STRABAG has a contractual obligation to transfer cash or other financial assets to another party. Initial recognition of non-derivative financial liabilities is made at fair value.

Trade payables are classified as current provided the company does not have an unconditional right to defer settlement of the liability for at least twelve months after the reporting period or within the normal business cycle.

The preparation of financial statements in conformity with IFRS requires estimates and assumptions to be made that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities and the reported amounts of revenue and expenses.

The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below.

(a) Recoverability of goodwill

The Group conducts an annual test to determine whether its goodwill is impaired in accordance with the accounting policies described in the section “Impairment of non-financial assets”. The recoverable amount of the CGUs was determined using fair value less costs of disposal. These calculations are based on assumptions about the expected business development and the recoverable margin. Estimates about the expected business development are based on the facts and circumstances prevailing at the time of preparation of the consolidated financial statements as well as on realistic assumptions about the future development of the global and industry-specific environment. In response to changes in these underlying conditions which deviate from the assumptions and are beyond the Management Board’s control, actual values may deviate from the estimated values.

All other things remaining equal, an annual 5% decrease of the free cash flow used to calculate the recoverable amount would result in a total impairment loss of all goodwill of T€ 1,338 (2023: T€ 1,818), while an isolated increase of the cost of capital by 1 percentage point would lead to an impairment of goodwill of T€ 3,195 (2023: T€ 7,219). These two effects together would trigger an impairment loss of T€ 7,372 (2023: T€ 9,275).

An extended sensitivity analysis was performed due to the current uncertainties in the economic environment and the associated price increases and supply bottlenecks. Due to the large number of different types of orders and the fact that a large part of the work included in the planning has not yet been commissioned, a worst-case scenario was determined with regard to the achievable cash flows. An annual and sustained decrease of 15% in the recoverable free cash flows and a simultaneous increase of 3 percentage points in the weighted average cost of capital would result in an impairment loss of T€ 40,770 (2023: T€ 26,939).

The write-offs would affect Czech companies in the materials and concrete production business within the South + East segment in the amount of T€ 7,077 (2023: T€ 7,209), several German construction companies in the North + West segment in the amount of T€ 1,800 (2023: T€ 2,064), several Austrian construction companies in the South + East segment in the amount of T€ 7,737 (2023: T€ 9,436), as well as several companies in the facility management business in the International + Special Divisions segment in the amount of T€ 24,156 (2023: T€ 8,230).

(b) Other non-current financial assets / provisions

Other non-current financial assets include US dollar receivables from a Chilean project company. One part of this receivable, Lien 1, carries a fixed interest rate. The second part of this receivable, Lien 2, bears a fixed interest rate and is subject to additional variable components and a possible final conversion into shares. Lien 1 is serviced before Lien 2. Lien 1 is measured at amortised cost. Lien 2 is serviced subject to available cash. The subsequent measurement of Lien 2 is therefore at fair value.

The carrying amounts of non-current receivables, which arose from the financial restructuring of a supplier credit from a large Chilean project (power plant), were recognised at fair value on completion of the project. The measurement was made on the basis of the cash flows that can be generated in the future using planned data from the project company, taking into account generally available data on electricity price and hydrological developments as well as the current interest rate environment.

In December 2022 and in the course of the 2023 financial year, tunnel collapses were reported, the cause of which remain unclear. The incidents led to a shutdown of the power plant in 2023, why further impairments were therefore recognised on these non-current receivables.

On top of this, the project company is asserting claims against STRABAG due to the alleged failure to complete the project on time. The payment made in November 2023 on the performance bond, which STRABAG believes was drawn improperly, was recognised as an expense in 2023.

The reconnaissance drilling in preparation of the remediation measures that were made in the 2024 financial year revealed collapsed sections that were longer than had been expected. The clean-up work following the collapses could therefore not be completed in the 2024 financial year and it is still unclear when the power plant can be put back into operation.

The arbitration proceedings initiated with regard to the core issues of (i) whether substantial completion has been achieved and (ii) who is to bear the costs of the clean-up, based on the causes of the collapse, continued in the 2024 financial year. Given the complexity of the matter, the arbitral tribunal is not expected to reach a decision before mid-2025. On the basis of the statements and assessments presented by the experts, the provisions for renovation and warranty formed in the previous year were re-evaluated and adjusted in amount.

Disclosure of the amount of the impairments and provisions existing as of 31 December 2024 is not possible due to the ongoing arbitration proceedings, as this would seriously compromise STRABAG’s position.

Due to the unclear cause of the damages, the complex legal circumstances and the long terms to maturity, the actual returns and the actual claim may deviate from the reported values.

(c) Recognition of revenue from construction contracts with customers and project developments

The revenue from construction contracts with customers is recognised over time. The Group estimates the work performed by the reporting date as a percentage of the total volume of the order backlog as well as the remaining contract cost to be incurred. If it is probable that the production costs will exceed the recoverable proceeds, an impairment is recognised up to the value of the contract asset; if the value of the respective contract asset is exceeded, an onerous contract provision is recognised. Technically complex and demanding projects, in particular, involve the risk that the estimate of the total cost deviates considerably from the actual cost incurred.

In the event of changes to the contract’s scope and/or price that remain disputed between the parties to the contract (claims and variation orders), revenue from claims and variation orders is estimated in accordance with the provisions on variable consideration under IFRS 15.50ff for the respective project. The estimate is based on qualitative and quantitative criteria.

The following factors must be taken into account when estimating the variable consideration:

The actual claims arising from claims and variation orders may therefore differ from the estimated amount, especially in the case of complex construction projects with a large number of different claims and variation orders as well as counterclaims of the client.

The above also applies to over-time recognition of revenue from project developments.

(d) Equity-accounted investments

The Group holds a 30% investment in Holcim Cement CE Holding GmbH. Holcim operates cement works in Austria, Hungary, the Czech Republic and Slovenia. The carrying amount of the investment amounted to T€ 198,312 on 31 December 2024 (2023: T€ 201,980). As earnings developed according to plan and because of the ongoing distributions, an impairment test was not required.

Deviations from the expected business development as well as developments in the economic environment that are beyond the Management Board’s control may influence the value of the investment.

(e) Income taxes

STRABAG has to calculate the actual income tax expected for each taxable entity and must assess the temporary differences arising from the different treatment of certain balance sheet items in the IFRS consolidated financial statements and the statutory financial statements required for tax purposes. The existence of temporary differences usually results in the recognition of deferred tax assets and liabilities in the consolidated financial statements.

The management must make assessments in the calculation of current and deferred tax. Deferred tax assets are recognised to the extent that their use is probable. The use of deferred tax assets depends on the possibility of realising sufficient taxable income under the respective tax type and jurisdiction under consideration of any possible legal restrictions regarding the maximum loss carry forward period. A number of different factors are used to assess the probability of the future usability of deferred tax assets, such as the past financial performance, operational planning, loss carry forward periods and tax planning strategies. If the actual results deviate from these estimates, or if these estimates must be adjusted in future periods, this could have a negative impact on the financial position, financial performance and cash flows. In the event of a changed assessment of the recoverability of deferred tax assets, the deferred tax assets which have been recognised are written down in profit or loss or, depending on their original formation, outside profit or loss; impaired deferred tax assets are similarly recognised either in profit or loss or outside profit or loss.

(f) Fair value of derivatives and other financial instruments

The fair value of financial instruments that are not traded in an active market is determined by using suitable valuation techniques selected from among a number of different methods. The assumptions used are mainly based on market conditions existing at the balance sheet date. The Group uses present value techniques to determine the fair value of a number of financial assets that are not traded in an active market.

(g) Rights from leases and lease liabilities

Within the STRABAG SE Group, a large number of the contracts are lease contracts with comparatively low annual rental expenses, of both limited and indefinite duration and with ordinary termination rights. The lease liability is determined by estimating the most likely duration in consideration of extension options and termination rights. All economic aspects for exercising or not exercising the options are taken into account. Deviations between the actual lease terms and these assumptions have an impact on the respective carrying amounts. The risk is reduced by the large number of stand-alone contracts, however.

(h) Severance and pension provisions

The present value of the severance and pension obligations depends on a number of different factors based on actuarial assumptions. One of the assumptions used to determine the net expenses or income for pensions is the discount rate. Any change to these assumptions will influence the carrying amount of the pension obligation.

The Group determines the appropriate discount rate at the end of every year. The discount rate is the interest rate used to determine the present value of future cash flows required to settle the obligation. For the purpose of determining the discount rate, the Group employs the interest rate of highest-grade industrial bonds in the same currency in which the benefits are paid and which have terms to maturity equivalent to those of the pension obligations.

Additional substantial assumptions relating to severance and pension obligations are based in part on market conditions. Further information and sensitivity analyses can be found in item (28) Provisions.

(i) Other provisions

Other construction-related provisions, in particular, involve the risk that in individual cases the actual costs for warranty obligations or remaining performance obligations will turn out higher or lower than expected. The balance sheet item other construction-related provisions is composed of several individual projects together, however, as a result of which the risk is reduced to the individual consideration of the projects. This also applies to provisions for recultivation and decommissioning obligations with regard to estimates of future costs and the measures prescribed by the various authorities in the individual countries that are not specified until the time of recultivation.

Group companies STRABAG AG and F. Lang u. K. Menhofer Baugesellschaft m.b.H. & Co. KG issued an acknowledgement as part of a settlement in the antitrust proceedings against them in Austria. Subsequently, the Federal Competition Authority (BWB) in July 2021 filed an application with the Cartel Court for a fine against the two companies in the amount of € 45.37 million.

The settlement is being made against the background of a criminal and antitrust investigation that was opened in spring 2017 against STRABAG AG and F. Lang u. K. Menhofer Baugesellschaft m.b.H. & Co. KG, along with several other construction companies, regarding allegations of anti-competitive agreements for construction projects in Austria in the period from 2002 to 2017. Both group companies cooperated fully with the Federal Competition Authority from the outset and ultimately issued an acknowledgement as part of a settlement. Their cooperation had a corresponding positive effect on the amount of the fine. In October 2021, the Cartel Court imposed the fine of € 45.37 million, thus confirming the amount requested by the Federal Competition Authority. The ruling was made public on 3 February 2022.

In July 2022, the Federal Competition Authority requested a review of the Cartel Court’s final decision regarding the imposed fine. In its decision from October 2022, the Cartel Court rejected the Federal Competition Authority’s application as inadmissible and upheld the view of STRABAG AG. The Federal Competition Authority appealed against this decision to the Austrian Supreme Court (OGH), which granted the appeal in a decision on 25 May 2023 on the grounds that the formal rejection of the Federal Competition Authority’s application without a substantive review by the Higher Regional Court was inadmissible.

In this context, it must be pointed out that the decision does not deprive STRABAG AG of its state’s witness status. Rather, the Supreme Court, referring to its previous rulings, clarified that the decision of the Federal Competition Authority to apply the state’s witness rule was made autonomously by the Federal Competition Authority and that the courts have no competence to review this decision.

Now it is up to the Higher Regional Court to review the merits of the Federal Competition Authority’s request. This means that the court must take the relevant evidence and consider both sides of the argument. The relevant proceedings before the Higher Regional Court are currently underway.

The Management Board is firmly convinced that the petition is unfounded. STRABAG SE cooperated fully and thoroughly with the Federal Competition Authority under the terms of the state’s witness programme. This cooperation made a significant contribution to clarifying the matter. In addition, STRABAG has since enhanced its compliance system through corporate-wide certification and has implemented a new type of monitoring system.

Multiple clients have asserted claims for damages against STRABAG. Settlement negotiations for an out-of-court solution are ongoing with several key clients. Other claims are already being asserted by clients through the courts.

Corresponding provisions were made in the consolidated financial statements for damage control and possible claims resulting from the cartel violations. The provision – with the exception of the time value of money – remained largely unchanged in the 2024 financial year. The specific amount of the provision is not stated due to the ongoing proceedings, as this would seriously jeopardise STRABAG’s position. Given the complexity of the matter (long period of time, large number of projects, very different clients, heterogeneous structures, etc.), it is extremely difficult to estimate the final extent to which STRABAG will be negatively impacted as a result. The actual amounts may therefore deviate from the amount provided for.

Provisions for ongoing and pending legal proceedings are formed on the basis of current assessments. The outcome of these legal proceedings cannot be determined or is subject to uncertainties. The actual claims from the legal proceedings may therefore differ from the provision amounts.
