The Consolidated Financial Statements of Tenaris have been prepared in accordance with International Financial Reporting Standards ("IFRS" or "IFRS Accounting Standards"), as issued by the International Accounting Standards Board ("IASB") and in accordance with IFRS as adopted by the European Union, under the historical cost convention, as modified by the revaluation of certain financial assets and liabilities (including derivative instruments) and plan assets at fair value. The Consolidated Financial Statements are, unless otherwise noted, presented in thousands of U.S. dollars ("\$").

Whenever necessary, certain comparative amounts have been reclassified to conform to changes in presentation in the current year.

The preparation of Consolidated Financial Statements in conformity with IFRS requires management to make certain accounting estimates and assumptions that might affect among others, the reported amounts of assets, liabilities, contingent liabilities, revenues and expenses. Actual results may differ from these estimates. The main areas involving material estimates or judgements are: impairment of goodwill and long-lived assets (notes II.H), impairment in investments in associates (note II.B); income taxes including recoverability of deferred tax assets (note II.O); obsolescence of inventory (note II.J); contingencies (note II.Q); allowance for trade receivables (note II.K); post-employment and other long-term benefits (note II.P); business combinations (notes II.B); useful lives of property, plant and equipment and other long-lived assets (notes II.E, II.F, II.H) and property title ownership restriction (note IV.28). During the year there were no significant changes in the material accounting estimates and judgements.

(1) Accounting pronouncements applicable as from January 1, 2023

Amendments to IAS 12 - International Tax Reform - Pillar Two Model Rules

In December 2021, the Organization for Economic Co-operation and Development ("OECD") released the Pillar Two model rules (the Global Anti-Base Erosion rules, or "GloBE") to reform international corporate taxation. Following Pillar Two OECD's initiative, the European Union adopted in December 2022 a directive to impose a global minimum taxation for multinational companies in the Union, to be effective as from 2024.

In May 2023, the IASB made narrow-scope amendments to IAS 12 setting an exception that provides relief from the requirement to recognize and disclose deferred taxes arising from enacted or substantively enacted tax laws that implement the Pillar Two model rules, including tax laws that implement qualified domestic minimum top-up taxes as per described in those rules.

On December 20, 2023, the Luxembourg Parliament approved the Pillar Two law transposing the EU Pillar Two Directive into domestic legislation. The law enters into force as from fiscal years starting on or after 31 December 2023.

The Company is within the scope of the rules, and therefore will be required to calculate its GloBE effective tax rate for each jurisdiction where it operates and will be liable to pay a top-up tax for the difference between its GloBE effective tax rate per jurisdiction and the 15% minimum rate, as from 2024. For more information see note 9.

Other accounting pronouncements that became effective during 2023 have no material effect on the Company's financial condition or results of operations.

(2) New accounting pronouncements not applicable as of December 31, 2023

Certain newly published accounting standards, amendments to accounting standards and interpretations are not mandatory for December 31, 2023 reporting periods and have not been early adopted by the Company. These standards, amendments or interpretations are not expected to have a material impact in the current or future reporting periods and on foreseeable future transactions.

B Group accounting

(1) Subsidiaries and transactions with non-controlling interests

Subsidiaries are all entities over which Tenaris has control. Tenaris controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. In some cases, the Company considers that it has the ability to affect returns through its power over an entity even if it holds less than 50% of the shares or voting rights of the subsidiary because it is able to prevail at all of the subsidiary's general meetings, which in turn allows Tenaris to nominate and appoint a majority of the subsidiary's board of directors. Subsidiaries are fully consolidated from the date on which control is exercised by the Company and are no longer consolidated from the date control ceases.

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

Contingent consideration is classified either as equity or as a financial liability. Amounts classified as a financial liability are subsequently remeasured to fair value with changes in fair value recognized in profit or loss.

If the business combination is achieved in stages, the acquisition date carrying value of the acquirer's previously held equity interest in the acquiree is remeasured to fair value at the acquisition date. Any gains or losses arising from such remeasurement are recognized in profit or loss.

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

When the Company ceases to have control or significant influence, any retained interest in the entity is remeasured to its fair value, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the group had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized in other comprehensive income are reclassified to profit or loss.

Material intercompany transactions, balances and unrealized gains (losses) on transactions between Tenaris subsidiaries have been eliminated in consolidation. However, since the functional currency of some subsidiaries is its respective local currency, some financial gains (losses) arising from intercompany transactions are generated. These are included in the Consolidated Income Statement under Other financial results.

(2) Non-consolidated companies

Non-consolidated companies are all entities in which Tenaris has significant influence but not control, generally accompanying a shareholding of between 20% and 50% of the voting rights. Investments in non-consolidated companies (associates and joint ventures) are accounted for by the equity method and are initially recognized at cost (as defined by IAS 28, "Investments in Associates and Joint Ventures"). The Company's investment in non-consolidated companies includes goodwill identified in acquisition, net of any accumulated impairment loss.

Under the equity method, the investments are initially recognized at cost and adjusted thereafter to recognize Tenaris's share of the post-acquisition profits or losses of the investee in profit or loss, and Tenaris's share of movements in other comprehensive income of the investee in other comprehensive income. Dividends received or receivable from associates and joint ventures are recognized as a reduction in the carrying amount of the investment.

If material, unrealized results on transactions between Tenaris and its non-consolidated companies are eliminated to the extent of Tenaris's interest in the non-consolidated companies. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment indicator of the asset transferred. Financial statements of nonconsolidated companies are adjusted where necessary to ensure consistency with IFRS.

The Company's pro-rata share of earnings in non-consolidated companies is recorded in the Consolidated Income Statement under Equity in earnings of non-consolidated companies. The Company's pro-rata share of changes in other comprehensive income is recognized in the Consolidated Statement of Comprehensive Income.

a) Ternium

At December 31, 2023, Tenaris held 11.46% in the share capital of Ternium S.A. ("Ternium"). The following factors and circumstances evidence that Tenaris has significant influence over Ternium:

  • both the Company and Ternium are under the indirect common control of San Faustin S.A. ("San Faustin");
  • four out of nine members of Ternium's board of directors (including Ternium's chairman) are also members of the Company's board of directors;
  • under the shareholders' agreement by and between the Company and Techint Holdings S.àr.l ("Techint"), a wholly owned subsidiary of San Faustin and Ternium's main shareholder, dated January 9, 2006 Techint, is required to take actions within its power to cause (a) one of the members of Ternium's board of directors to be nominated by the Company and (b) any director nominated by the Company to be removed from Ternium's board of directors only pursuant to previous written instructions of the Company.

b) Usiminas

At December 31, 2023, Tenaris held, through its Brazilian subsidiary Confab Industrial S.A. ("Confab"), 47.5 million ordinary shares and 1.3 million preferred shares of Usinas Siderúrgicas de Minas Gerais S.A. - Usiminas ("Usiminas"), representing 6.76% of its shares with voting rights and 3.96% of its total share capital.

Confab's participation in Usiminas share capital is the result of a series of acquisitions, the first of which was performed on January 16, 2012, pursuant to which Ternium (through certain of its subsidiaries) and Confab acquired a large block of Usiminas ordinary shares and joined Usiminas' existing control group. Subsequently, in 2016, Ternium and Confab subscribed to additional ordinary shares and to preferred shares.

More recently, on March 30, 2023, Confab, together with Ternium (through its subsidiaries Ternium Investments and Ternium Argentina), agreed to acquire an additional 68.7 million ordinary shares of Usiminas at a price of BRL10 per ordinary share. The transaction closed on July 3, 2023 and was financed with cash on hand. Tenaris paid approximately BRL110 million (approximately \$22.7 million) in cash for approximately 11 million ordinary shares, increasing its participation in the Usiminas control group to 9.8%.

The Usiminas control group comprises the T/T Group, formed by Ternium Investments, Ternium Argentina and Confab; the NSC Group, comprising Nippon Steel Corporation, Mitsubishi and MetalOne; and Usiminas' employee pension fund, Previdência Usiminas. At December 31, 2023, the Usiminas control group held, in the aggregate, 483.6 million ordinary shares, representing approximately 68.6% of Usiminas' voting capital and the T/T Group held an aggregate participation of 61.3% in the control group (with 51.5% of the control group's participation corresponding to Ternium's subsidiaries, and remaining 9.8% corresponding to Confab); the NSC Group and Previdência Usiminas held 31.7% and 7%, respectively, in the control group.

Upon closing of the July 3, 2023 acquisition, the then existing Usiminas shareholders agreement governing the relationship between the T/T Group, the NSC Group and Previdência Usiminas was replaced by a new shareholders agreement setting forth a new governance structure for Usiminas. The T/T Group is now entitled to nominate a majority of the Usiminas board of directors, the chief executive officer and four other members of the Usiminas board of officers. Of the positions allocated to the T/T Group, Tenaris retains the right to nominate one member of the Usiminas board of directors and one member of the Usiminas board of officers. Ordinary decisions may be approved with a 55% majority of Usiminas' control group shares.

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

Confab and the Ternium entities party to the Usiminas shareholders agreement have a separate shareholders agreement governing their respective rights and obligations as members of the T/T Group. Under such separate agreement, Confab enjoys certain rights with respect to the governance of Usiminas, including, among others, the ability to nominate certain Usiminas' officers and directors. Those circumstances evidence that Tenaris continues having significant influence over Usiminas and, as a result, continues accounting for its investment under the equity method.

c) Techgen

Techgen S.A. de C.V. ("Techgen"), which operates an electric power plant in Mexico, is a joint venture company owned 48% by Ternium, 30% by Tecpetrol International S.A. ("Tecpetrol") and 22% by Tenaris. The Company, Ternium and Tecpetrol are parties to a shareholders' agreement relating to the governance of Techgen and are under the indirect common control of San Faustin. Based on the facts stated above, the Company has determined that it has significant influence over this entity.

d) Global Pipe Company

Global Pipe Company ("GPC") is a joint venture, established in 2010 and located in Jubail, Saudi Arabia, which manufactures LSAW pipes. Until May 16, 2023, Tenaris, through its subsidiary Saudi Steel Pipe Company ("SSPC") owned 35% of the share capital of GPC and, accordingly was a non-consolidated company.

On May 17, 2023, SSPC acquired an additional 22.3% interest in GPC reaching a participation of 57.3%. The Company consolidates GPC's balances and results of operations as from May 17, 2023.

For more information on GPC's acquisition and its accounting treatment see note 34 "Business Combinations - Global Pipe Company acquisition".

Tenaris carries its investments in non-consolidated companies under the equity method, with no additional goodwill or intangible assets recognized. Tenaris reviews investments in non-consolidated companies for impairment whenever events or changes in circumstances indicate that the asset's carrying amount may not be recoverable. For more information see note 14 to these Consolidated Financial Statements.

C Segment information

The Company is organized in one major business segment, Tubes, which is also the reportable operating segment. All other business activities and operating segments that are not required to be separately reported are disclosed in the Other segment.

The Tubes segment includes the production and sale of both seamless and welded steel tubular products and related services mainly for the oil and gas industry, particularly oil country tubular goods ("OCTG") used in drilling operations, and for other industrial applications with production processes that consist in the transformation of steel into tubular products. Business activities included in this segment are mainly dependent on the worldwide oil and gas industry, as this industry is a major consumer of steel pipe products, particularly OCTG used in drilling activities. Demand for steel pipe products from the oil and gas industry has historically been volatile and depends primarily upon the number of oil and natural gas wells being drilled, completed and reworked, and the depth and drilling conditions of these wells. Sales are generally made to end users, with exports being done through a centrally managed global distribution network and domestic sales are made through local subsidiaries.

The Other segment includes all business activities related to the production and selling of sucker rods, coiled tubing, tubes used for plumbing and construction applications, oilfield / hydraulic fracturing services, the recently acquired coating business and others as energy and raw materials that exceed internal requirements.

Tenaris's Chief Operating Decision Maker ("CODM") reviews operating and financial performance information with senior management on a monthly basis. This information differs from IFRS principally as follows:

  • the use of direct cost methodology to calculate the inventories, while under IFRS it is at full cost, including absorption of production overheads and depreciation;
  • the use of costs based on previously internally defined cost estimates, while, under IFRS, costs are calculated at historical cost, mainly on a FIFO basis;
  • any currency translation adjustment reclassification, when applicable, for companies that under IFRS had a different functional currency than the U.S. dollar; and
  • other timing differences, if any.

Tenaris presents its geographical information in four areas: North America, South America, Europe and Asia Pacific, Middle East and Africa. For purposes of reporting geographical information, net sales are allocated to geographical areas based on the customer's location; allocation of assets, capital expenditures and associated depreciations and amortizations are based on the geographical location of the assets.

D Foreign currency translation

(1) Functional and presentation currency

IAS 21 (revised), "The effects of changes in foreign exchange rates" defines the functional currency as the currency of the primary economic environment in which an entity operates.

The functional and presentation currency of the Company is the U.S. dollar. The U.S. dollar is the currency that best reflects the economic substance of the underlying events and circumstances relevant to Tenaris's global operations.

Starting January 1, 2023, the Company changed the functional currency of its Brazilian subsidiaries, from the Brazilian Real to the U.S. dollar.

This decision was a result of a significant increase of its Brazilian Subsidiaries' participation in the OCTG and line pipe international markets, a trend which started in recent years and has been strengthened in 2022, an increased level of integration of the local operations within Tenaris's international commercial and supply chain system, as well as the fact that the main purchase agreement contracts and the long term sales agreement contracts with major international and local oil companies are either entered or indexed to the U.S. dollar. Local steel prices are also being affected by the U.S. dollar / Brazilian Real fluctuations.

Except for the Italian subsidiaries whose functional currency is the Euro and two recently acquired subsidiaries whose functional currencies are the Canadian Dollar and the Norwegian Krone, Tenaris determined that the functional currency of its other subsidiaries is the U.S. dollar, based on the following principal considerations:

  • sales are mainly negotiated, denominated and / or settled in U.S. dollars. If priced in a currency other than the U.S. dollar, the sales price may consider exposure to fluctuation in the exchange rate against the U.S. dollar;
  • prices of their critical raw materials and inputs are priced and / or settled in U.S. dollars;
  • transaction and operational environment and the cash flow of these operations have the U.S. dollar as reference currency;
  • there is a significant level of integration of the local operations within Tenaris's international global distribution network;
  • net financial assets and liabilities are mainly received and maintained in U.S. dollars; and
  • the exchange rate of certain legal currencies has long-been affected by recurring and severe economic crises.

(2) Transactions in currencies other than the functional currency

Transactions in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the date of the transactions or valuation where items are re-measured.

At the end of each reporting period: (i) monetary items denominated in currencies other than the functional currency are translated using the closing rates; (ii) non-monetary items that are measured in terms of historical cost in a currency other than the functional currency are translated using the exchange rates prevailing at the date of the transactions; and (iii) non-monetary items that are measured at fair value in a currency other than the functional currency are translated using the exchange rates prevailing at the date when the fair value was determined.

Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at yearend exchange rates of monetary assets and liabilities denominated in currencies other than the functional currency are recorded as gains and losses from foreign exchange and included in Other financial results in the Consolidated Income Statement, except when deferred in equity as qualifying cash flow hedges and qualifying net investment hedges.

(3) Translation of financial information in currencies other than the functional currency

Results of operations for subsidiaries whose functional currencies are not the U.S. dollar are translated into U.S. dollars at the average exchange rates for each quarter of the year. Financial statement positions are translated at the period-end exchange rates. Translation differences are recognized in a separate component of equity as currency translation adjustments. In the case of a sale or other disposal of any of such subsidiaries, any accumulated translation difference would be recognized in the Consolidated Income Statement as a gain or loss from the sale or disposal following IAS 21.

Goodwill and fair value adjustments arising from the acquisition of a foreign operation are treated as assets and liabilities of the foreign operation and translated at the closing exchange rate.

E Property, plant and equipment

Property, plant and equipment are recognized at historical acquisition or construction cost less accumulated depreciation and impairment losses. Historical cost includes expenditure that is directly attributable to the acquisition of the items. Property, plant and equipment acquired through acquisitions accounted for as business combinations have been valued initially at the fair market value of the assets acquired.

Major overhaul and rebuilding expenditures are capitalized as property, plant and equipment only when it is probable that future economic benefits associated with the item will flow to the Company and the investment enhances the condition of assets beyond its original condition. The carrying amount of the replaced part is derecognized. Maintenance expenses on manufacturing properties are recorded as cost of products sold in the year in which they are incurred.

Cost may also include transfers from equity of any gains or losses on qualifying cash flow hedges of foreign currency purchases of property, plant and equipment.

Borrowing costs that are attributable to the acquisition or construction of certain capital assets are capitalized as part of the cost of the asset, in accordance with IAS 23 (revised), "Borrowing Costs". Assets for which borrowing costs are capitalized are those that require a substantial period of time to prepare for their intended use.

The depreciation method is reviewed at each year end. Depreciation is calculated using the straight-line method to depreciate the cost of each asset to its residual value over its estimated useful life, as follows:

Land No Depreciation
Buildings and improvements 30-50 years
Plant and production equipment 10-40 years
Vehicles, furniture and fixtures, and other equipment 4-10 years

The assets' residual values and useful lives of significant plant and production equipment are reviewed and adjusted, if appropriate, at each year-end date. An asset's carrying amount is written down immediately to its recoverable amount if the asset's carrying amount is greater than its estimated recoverable amount.

Management's re-estimation of assets useful lives, performed in accordance with IAS 16, "Property, Plant and Equipment", resulted in additional depreciation expenses of approximately \$39 million for 2022, and did not materially affect depreciation expenses for 2023 and 2021.

Tenaris depreciates each significant part of an item of property, plant and equipment for its different production facilities that (i) can be properly identified as an independent component with a cost that is significant in relation to the total cost of the item, and (ii) has a useful operating life that is different from another significant part of that same item of property, plant and equipment.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount of assets and are recognized under Other operating income or Other operating expenses in the Consolidated Income Statement.

F Intangible assets

(1) Goodwill

Goodwill represents the excess of the acquisition cost over the fair value of Tenaris's share of net identifiable assets acquired as part of business combinations determined mainly by independent valuations. Goodwill is tested at least annually for impairment and carried at cost less accumulated impairment losses. Impairment losses on goodwill are not reversed. Goodwill is included in the Consolidated Statement of Financial Position under Intangible assets, net.

For the purpose of impairment testing, goodwill is allocated to a cash generating unit ("CGU") or group of CGUs that are expected to benefit from the business combination which generated the goodwill being tested.

(2) Information systems projects

Costs associated with maintaining computer software programs are generally recognized as an expense as incurred. However, costs directly related to the development, acquisition and implementation of information systems are recognized as intangible assets if it is probable that they have economic benefits exceeding one year and comply with the recognition criteria of IAS 38, "Intangible Assets".

Information systems projects recognized as assets are amortized using the straight-line method over their useful lives, generally not exceeding a period of 3 years. Amortization charges are mainly classified as Selling, general and administrative expenses in the Consolidated Income Statement.

Management's re-estimation of assets useful lives, performed in accordance with IAS 38, did not materially affect amortization expenses for 2023, 2022 and 2021.

(3) Licenses, patents, trademarks and proprietary technology

Licenses, patents, trademarks, and proprietary technology are initially recognized at fair value at the acquisition date. Licenses, patents, proprietary technology and those trademarks that have a finite useful life are carried at cost less accumulated amortization. Amortization is calculated using the straight-line method to allocate the cost over their estimated useful lives, which are in the range between 3 and 20 years. Amortization charges are mainly classified as Cost of sales in the Consolidated Income Statement.

The balance of acquired trademarks that have indefinite useful lives according to external appraisal amounts to \$86.7 million at December 31, 2023, 2022 and 2021, and are included in Hydril CGU. Main factors considered in the determination of the indefinite useful lives include the years that they have been in service and their recognition among customers in the industry.

Management's re-estimation of assets useful lives, performed in accordance with IAS 38, did not materially affect amortization expenses for 2023, 2022 and 2021.

(4) Research and development

Research expenditures as well as development costs that do not fulfill the criteria for capitalization are recorded as Cost of sales in the Consolidated Income Statement as incurred. Research and development expenditures included in Cost of sales for the years 2023, 2022 and 2021 totaled \$60.0 million, \$50.7 million and \$45.3 million, respectively.

Capitalized costs were not material for the years 2023, 2022 and 2021.

(5) Customer relationships

In accordance with IFRS 3, "Business Combinations" and IAS 38, Tenaris has recognized the value of customer relationships separately from goodwill attributable to the acquisition of Maverick Tube Corporation ("Maverick") and Hydril Company ("Hydril") groups, SSPC, Ipsco Tubulars Inc. ("IPSCO") and the more recent acquisition of Mattr's pipe coating business unit.

Customer relationships acquired in a business combination are recognized at fair value at the acquisition date, have a finite useful life and are carried at cost less accumulated amortization. Amortization is calculated using the straight line method over the initial expected useful lives which were approximately 14 years for Maverick, 10 years for Hydril, 9 years for SSPC, 3 years for IPSCO, and 4 months for Mattr's pipe coating business unit.

In 2022, the Company reviewed the useful life of SSPC's customer relationships and decided to reduce it from 5 years to 3 years, consequently a higher amortization charge of approximately \$4.1 million was recorded in the Consolidated Income Statement under Selling, general and administrative expenses for the year ended December 31, 2022.

Management's re-estimation of assets useful lives, performed in accordance with IAS 38, did not affect amortization expenses for 2023 and 2021.

As of December 31, 2023 the net book value of SSPC's customer relationship amounted to \$26.4 million, with a residual useful life of 1 year and 9 months, Mattr's amounted to \$21.5, with a residual useful life of 3 months, while IPSCO's, Maverick's and Hydril's customer relationships were fully amortized.

G Right-of-use assets and lease liabilities

Leases are recognized as a right-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the group. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The right-of-use asset is depreciated over the lease term on a straight-line basis.

Lease liabilities include the net present value of i) fixed payments, less any lease incentives receivable, ii) variable lease payments that are based on an index or a rate, iii) amounts expected to be payable by the lessee under residual value guarantees, iv) the exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and v) payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option.

The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be determined, the lessee's incremental borrowing rate is used, being the rate that the lessee would have to pay to borrow the funds necessary to obtain an asset of similar value in a similar economic environment with similar terms and conditions.

Right-of-use assets are measured at cost comprising the amount of the initial measurement of the lease liability, any lease payments made at or before the commencement date less any lease incentives received and any initial direct costs incurred by the lessee.

In determining the lease term, management considers all facts and circumstances that create an economic incentive to exercise an extension option or early termination, or not to exercise a termination option. Extension options (or periods after termination options) are only included in the lease term if the lease is reasonably certain to be extended (or not terminated).

Payments associated with short-term leases, variable leases and leases of low value assets are recognized on a straightline basis as expenses in profit or loss. Short-term leases are leases with a lease term of 12 months or less.

H Impairment of non-financial assets

Long-lived assets including identifiable intangible assets are reviewed for impairment at the lowest level for which there are separately identifiable cash flows ("CGU"). Most of the Company's principal subsidiaries that constitute a CGU have a single main production facility and, accordingly, each of such subsidiaries represents the lowest level of asset aggregation that generates largely independent cash inflows.

Assets that are subject to amortization or depreciation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Intangible assets with indefinite useful lives, including goodwill, are subject to at least an annual impairment test, or are tested more frequently if events or circumstances indicate that the carrying amount value may be impaired. In some situations where there have not been significant changes to CGU assets and liabilities as well as external and internal events and circumstances which could materially alter the recoverable amount of the CGU, the most recent detailed calculation of recoverable amount made in a preceding period may be used in the impairment test for that CGU in the current period.

In assessing whether there is any indication that a CGU may be impaired, external and internal sources of information are analyzed. Material facts and circumstances specifically considered in the analysis usually include the discount rate used in Tenaris's cash flow projections and the business condition in terms of competitive, economic and regulatory factors, such as the cost of raw materials, oil and gas prices, and the evolution of the rig count.

An impairment loss is recognized for the amount by which the asset's carrying amount exceeds its recoverable amount. The recoverable amount is the higher between the asset's value in use and fair value less costs of disposal. Any impairment loss is allocated to reduce the carrying amount of the assets of the CGU in the following order:

  • (a) first, to reduce the carrying amount of any goodwill allocated to the CGU; and
  • (b) then, to the other assets of the unit (group of units) pro-rata on the basis of the carrying amount of each asset in the unit (group of units), considering not to reduce the carrying amount of the asset below the highest of its fair value less cost of disposal, its value in use or zero.

Value in use is calculated by discounting the estimated cash flows over a five year period (or higher if the period can be justified) based on forecasts approved by management. For the subsequent years beyond the five-year period, a terminal value is calculated based on perpetuity considering a nominal growth rate of 2% taking into account among others, mainly the historical inflation rate.

For purposes of calculating the fair value less costs of disposal, Tenaris uses the estimated value of future cash flows that a market participant could generate from the corresponding CGU.

Management judgment is required to estimate discounted future cash flows. Actual cash flows and values could vary significantly from the forecasted future cash flows and related values derived using discounting techniques.

Non-financial assets other than goodwill that suffered an impairment are reviewed for possible reversal at each reporting date. For more information on impairment charges see note 5 to these Consolidated Financial Statements.

I Other investments

Other investments consist primarily of investments in financial instruments and time deposits with a maturity of more than three months at the date of purchase.

Certain non-derivative financial assets that the Company held not for trading have been categorized as financial assets at fair value through other comprehensive income ("FVOCI"), as the business model objective is achieved by both holding financial assets in order to collect contractual cash flows and selling financial assets. They are carried at fair value and interest income from these financial assets is included in finance income using the effective interest rate method. Unrealized gains or losses are recorded as a fair value adjustment in the Consolidated Statement of Comprehensive Income and transferred to the Consolidated Income Statement when the financial asset is disposed. Exchange gains and losses and impairments related to the financial assets are immediately recognized in the Consolidated Income Statement. FVOCI instruments with maturities greater than 12 months after the balance sheet date are included in non-current assets.

Other investments in financial instruments and time deposits are categorized as financial assets at fair value through profit or loss ("FVPL") because such investments are held for trading and their performance is evaluated on a fair value basis. The results of these investments are recognized in Financial Results in the Consolidated Income Statement.

Purchases and sales of financial investments are recognized as of their settlement date.

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

J Inventories

Inventories are stated at the lower between cost and net realizable value. The cost of finished goods and goods in process is comprised of raw materials, direct labor, utilities, freights and other direct costs and related production overhead costs, and it excludes borrowing costs. The allocation of fixed production costs, including depreciation and amortization charges, is based on the normal level of production capacity. Inventories cost is mainly based on the FIFO method. Tenaris estimates the net realizable value of inventories by grouping, where applicable, similar or related items. Net realizable value is the estimated selling price in the ordinary course of business, less any estimated costs of completion and selling expenses. Goods in transit as of year-end are valued based on the supplier's invoice cost.

Tenaris establishes an allowance for obsolete or slow-moving inventories related to finished goods, goods in process, supplies and spare parts. For slow moving or obsolete finished products, an allowance is established based on management's analysis of product aging. An allowance for obsolete and slow-moving inventory of supplies and spare parts is established based on management's analysis of such items to be used as intended and the consideration of potential obsolescence due to technological changes, aging and consumption patterns.

K Trade and other receivables

Trade and other receivables are recognized initially at fair value that corresponds to the amount of consideration that is unconditional unless they contain significant financing components. The Company holds trade receivables with the objective to collect the contractual cash flows and therefore measures them subsequently at amortized cost using the effective interest method. Due to their short-term nature, their carrying amount is considered to be the same as their fair value.

Tenaris applies the IFRS 9 "Financial Instruments" simplified approach to measure expected credit losses, which uses a lifetime expected loss allowance for all trade receivables. To measure the expected credit losses, trade receivables have been grouped based on shared credit risk characteristics and the days past due. The expected loss rates are based on the payment profiles of sales over a period of three years and the corresponding historical credit losses experienced within this period. The expected loss allowance also reflects current and forward-looking information on macroeconomic factors affecting the ability of each customer to settle the receivables.

L Cash and cash equivalents

Cash and cash equivalents are comprised of cash at banks, liquidity funds and short-term investments with a maturity of less than three months at the date of purchase which are readily convertible to known amounts of cash. Assets recorded in cash and cash equivalents are carried at fair market value or at historical cost which approximates fair market value.

In the Consolidated Statement of Financial Position, bank overdrafts are included in Borrowings in current liabilities.

For the purposes of the Consolidated Statement of Cash Flows, Cash and cash equivalents includes overdrafts.

M Equity

(1) Equity components

The Consolidated Statement of Changes in Equity includes:

  • the value of share capital, legal reserve, share premium and other distributable reserves calculated in accordance with Luxembourg law;
  • the currency translation adjustment, treasury shares, other reserves, retained earnings and non-controlling interest calculated in accordance with IFRS.

(2) Share capital

The Company has an authorized share capital of a single class of 2.5 billion shares having a nominal value of \$1.00 per share. Total ordinary shares issued as of December 31, 2023, 2022 and 2021 were 1,180,536,830 with a par value of \$1.00 per share with one vote each. Total ordinary shares outstanding as of December 31, 2023, were 1,167,888,739 and as of December 31, 2022 and 2021 were 1,180,536,830 with a par value of \$1.00 per share with one vote each. Outstanding shares do not include treasury shares. All issued shares are fully paid.

(3) Treasury Shares

Acquisitions of treasury shares are recorded at acquisition cost, deducted from equity until disposal or cancellation. Any potential gains or losses on disposal of treasury shares are recognized under Other reserves in the Consolidated Statement of Changes in Equity. Treasury shares outstanding as of December 31, 2023, were 12,648,091.

(4) Dividends distribution by the Company to shareholders

Dividends distributions are recorded in the Company's financial statements when Company's shareholders have the right to receive the payment, or when interim dividends are approved by the Board of Directors in accordance with the bylaws of the Company.

Dividends may be paid by the Company to the extent that it has distributable retained earnings, calculated in accordance with Luxembourg law. See note 27 (iii) to these Consolidated Financial Statements.

N Borrowings

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

O Current and deferred income tax

The income tax expense or credit for the period is the tax payable or recoverable on the current period's taxable income based on the applicable income tax rate for each jurisdiction adjusted by changes in deferred tax assets and liabilities attributable to temporary differences and to unused tax losses. Current and deferred tax is recognized in the Consolidated Income Statement, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In these cases, the tax is also recognized in other comprehensive income or directly in equity, respectively.

The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the reporting date in the countries where the Company's subsidiaries operate and generate taxable income.

Deferred income tax is recognized applying the liability method on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. The temporary differences arise mainly from net operating loss carry-forwards, the effect of currency translation on depreciable fixed assets and inventories, depreciation on property, plant and equipment, valuation of inventories, provisions for post-employment benefits and other long-term employee benefits and fair value adjustments of assets acquired in business combinations. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the time period when the asset is realized or the liability is settled, based on tax laws that have been enacted or substantively enacted at the reporting date.

Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation and considers whether it is probable that a taxation authority will accept an uncertain tax treatment. The Company measures its tax balances either based on the most likely amount or the expected value, depending on which method provides a better prediction of the resolution of the uncertainty.

Deferred tax assets are recognized to the extent that it is probable that future taxable profits will be available against which the temporary differences and losses can be utilized. At the end of each reporting period, Tenaris reassesses unrecognized deferred tax assets. Tenaris recognizes a previously unrecognized deferred tax asset to the extent that it has become probable that future taxable income will allow the deferred tax asset to be recovered.

Deferred tax liabilities and assets are not recognized for temporary differences between the carrying amount and tax basis of investments in foreign operations where the company is able to control the timing of the reversal of the temporary differences and it is probable that the differences will not reverse in the foreseeable future.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets and liabilities and when the deferred tax balances relate to the same taxation authority. Current tax assets and tax liabilities are offset where the entity has a legally enforceable right to offset and intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously.

Deferred tax assets and liabilities are re-measured if tax rates change. These amounts are charged or credited to the Consolidated Income Statement or to the item Other comprehensive income in the Consolidated Statement of Comprehensive Income, depending on the account to which the original amount was charged or credited.

P Employee benefits

(1) Short-term obligations

Liabilities for wages and salaries are recognized in respect of employees' services up to the end of the reporting period and are measured at the amounts expected to be paid when the liabilities are settled. The liabilities are presented as current employee benefit obligations in the balance sheet.

(2) Post-employment benefits

The Company has defined benefit and defined contribution plans. A defined benefit plan is a pension plan that defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service and compensation.

The liability recognized in the statement of financial position in respect of defined benefit pension plans is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets, if any. The defined benefit obligation is calculated annually (at year end) by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash flows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related pension obligation.

Remeasurement gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or credited to equity in Other comprehensive income in the period in which they arise. Past-service costs are recognized immediately in the Income Statement.

For defined benefit funded plans, net interest income / expense is calculated based on the surplus or deficit derived by the difference between the defined benefit obligations less fair value of plan assets.

For defined contribution plans, the Company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The Company has no further payment obligations once the contributions have been paid. The contributions are recognized as employee benefit expenses when they are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.

Tenaris sponsors funded and unfunded defined benefit pension plans in certain subsidiaries. The most significant are:

  • An unfunded defined benefit employee retirement plan for certain senior officers. The plan is designed to provide certain benefits to those officers (additional to those contemplated under applicable labor laws) in case of termination of the employment relationship due to certain specified events, including retirement. This unfunded plan provides defined benefits based on years of service and final average salary. As of December 31, 2023 the outstanding liability for this plan amounts to \$48.1 million.
  • Employees' service rescission indemnity. The cost of this obligation is charged to the Consolidated Income Statement over the expected service lives of employees. This provision is primarily related to the liability accrued for employees at Tenaris's Italian subsidiary. As from January 1, 2007 as a consequence of a change in an Italian law, employees were entitled to make contributions to external funds, thus, Tenaris's Italian subsidiary pays every year the required contribution to the funds with no further obligation. As a result, the plan changed from a defined benefit plan to a defined contribution plan effective from that date, but only limited to the contributions of 2007 onwards. As of December 31, 2023 the outstanding liability for this plan amounts to \$10.6 million.
  • Funded retirement benefit plan held in the U.S. for the benefit of some employees hired prior a certain date, frozen for the purposes of credited service as well as determination of final average pay for the retirement benefit calculation. Plan assets consist primarily of investments in equities and money market funds. Additionally, an unfunded post-retirement health and life plan is in place that offers limited medical and life insurance benefits to the retirees, frozen to new participants. As of December 31, 2023 the outstanding liability for these plans amounts to \$5.6 million.
  • Funded retirement benefit plans held in Canada for salary and hourly employees hired prior to a certain date based on years of service and, in the case of salaried employees, final average salary. Plan assets consist primarily of annuities purchased from an insurance company for the benefit of current and future retirees, investments in debt and equity instruments. Both plans were replaced for defined contribution plans. Effective June 2016 the salary plan was frozen for the purposes of credited service as well as determination of final average pay. As of December 31, 2023 the plan was overfunded and the net assets related to this plan amounted to \$10.8 million.

(3) Other long-term benefits

During 2007, Tenaris launched an employee retention and long-term incentive program ("the Program") applicable to certain senior officers and employees of the Company, who will be granted a number of units throughout the duration of the Program. The value of each of these units is based on Tenaris's shareholders' equity (excluding non-controlling interest). Until the end of 2017, the units were vested ratably over a period of four years and were mandatorily redeemed by the Company ten years after grant date, with the option of an early redemption at seven years after the grant date. Since 2018, the units are vested ratably over the same period and are mandatorily redeemed by the Company seven years after grant date.

The beneficiaries of the Program are entitled to receive cash amounts based on: (i) the amount of dividend payments made by Tenaris to its shareholders and (ii) the number of units held by each beneficiary to the Program. The payment of the benefit is tied to the book value of the shares, and not to their market value. Tenaris valued this long-term incentive program as a long-term benefit plan as classified in IAS 19, "Employee Benefits".

As of December 31, 2023 and 2022, the outstanding liability corresponding to the Program amounts to \$119.6 million and \$94.4 million, respectively. The total value of the units granted (vested and unvested) to date under the program, considering the number of units and the book value per share as of December 31, 2023 and 2022, is \$144.0 million and \$123.9 million, respectively.

(4) Termination benefits

Termination benefits are payable when employment is terminated by Tenaris before the normal retirement date, or when an employee accepts voluntary redundancy in exchange for these benefits. Tenaris recognizes termination benefits at the earlier of the following dates: (a) when it can no longer withdraw the offer of those benefits; and (b) when the costs for a restructuring that is within the scope of IAS 37 involves the payment of terminations benefits. In the case of an offer made to encourage voluntary redundancy, the termination benefits are measured based on the number of employees expected to accept the offer.

(5) Other compensation obligations

Employee entitlements to annual leave, long-service leave, sick leave and other bonuses and compensations obligations are accrued as earned.

Compensation to employees in the event of dismissal is charged to income in the year in which it becomes payable.

Q Provisions

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

If Tenaris expects to be reimbursed for an accrued expense, as would be the case for an expense or loss covered under an insurance contract, and reimbursement is considered virtually certain, the expected reimbursement is recognized as a receivable.

This note should be read in conjunction with note 27 to these Consolidated Financial Statements.

R Trade and other payables

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

S Revenue recognition

Revenue comprises the fair value of the consideration received or receivable for the sale of goods and rendering of services in the ordinary course of Tenaris's activities. The revenue recognized by the Company is measured at the transaction price of the consideration received or receivable to which the Company is entitled to, reduced by estimated returns and other customer credits, such as discounts and volume rebates, based on the expected value to be realized and after eliminating sales within the group.

Revenue is recognized at a point in time or over time from sales when control has been transferred and there is no unfulfilled performance obligation that could affect the acceptance of the product by the customer. The control is transferred upon delivery. Delivery occurs when the products have been shipped to the specific location, the risks of obsolescence and loss have been transferred and either the customer has accepted the product in accordance with the sales contract, the acceptance provisions have lapsed or the Company has objective evidence that all criteria for acceptance have been satisfied, including all performance obligations. These conditions are determined and analyzed on a contract by contract basis to ensure that all performance obligations are fulfilled. In particular, Tenaris verifies customer acceptance of the goods, the satisfaction of delivery terms and any other applicable condition.

For bill and hold transactions revenue is recognized only to the extent that (a) the reason for the bill and hold arrangement must be substantive (for example, the customer has requested the arrangement); (b) the products have been specifically identified and are ready for delivery; (c) the Company does not have the ability to use the product or to direct it to another customer; (d) the usual payment terms apply.

The Company's contracts with customers do not provide any material variable consideration, other than discounts, rebates and right of return. Discounts and rebates are recognized based on the most likely value and rights of return are based on expected value considering past experience and contract conditions.

Where the contracts include multiple performance obligations, the transaction price is allocated to each performance obligation based on the stand-alone selling prices. Where these are not directly observable, they are estimated based on the expected cost plus margin.

There are no judgements applied by management that significantly affect the determination of timing of satisfaction of performance obligations, nor the transaction price and amounts allocated to different performance obligations.

Tenaris provides services primarily related to goods sold, which represent a non-material portion of sales revenue and mainly include:

Pipe Management Services: This comprises mainly preparation of the pipes ready to be run, delivery to the customer, storage services and rig return.

Field Services: Comprises field technical support and running assistance.

These services are rendered in connection to the sales of goods and are attached to contracts with customers for the sale of goods. A significant portion of service revenue is recognized in the same period as the goods sold. There are no distinct uncertainties in the revenues and cash flows of the goods sold and services rendered as they are included in the same contract, have the same counterparty and are subject to the same conditions.

The Company also provides hydraulic fracturing, coiled tubing and coating services. The revenue related to these services is included in the Other segment.

Revenue from providing services is recognized over time in the accounting period in which the services are rendered.

The following inputs and outputs methods are applied to recognize revenue considering the nature of service:

Storage services: the Company provides storage services in owned or third-party warehouses, subject to a variable fee to be invoiced. This fee is determined based on the time that the customer maintains the material in the warehouse and the amount of the material stored. In the majority of cases, to quantify the amount to be invoiced in any given month, the monthly average fee of storage per ton is multiplied by the monthly average stock stored (in tons).

Freights: the revenue is recognized on a pro rata basis considering the units delivered and time elapsed.

Field services: the revenue is recognized considering output methods, in particular surveys of service completion provided by the customer.

The Company does not expect to have any contracts where the period between the transfer of the promised goods or services to the customer and payment by the customer exceeds one year. As a consequence, considering that the contracts do not include any significant financing component, the Company does not adjust any of the transaction prices for the time value of money. For this reason, the Company is also applying the practical expedient not to disclose details on transaction prices allocated to the remaining performance obligations as of the end of the reporting period.

Tenaris only provides standard quality warranties assuring that the goods sold will function as expected or are fit for their intended purpose, with no incremental service to the customer. Accordingly, warranties do not constitute a separate performance obligation.

Other revenues earned by Tenaris are recognized on the following basis:

  • Interest income: on the effective yield basis.
  • Dividend income from investments in other companies: when Tenaris's right to receive payment is established.
  • Net income from other sales: when control is transferred to the customer.
  • Construction / coating contracts revenues: in accordance with the stage of the project completion.

T Cost of sales and other selling expenses

Cost of sales and other selling expenses are recognized in the Consolidated Income Statement on the accrual basis of accounting.

Commissions, freights and other selling expenses, including shipping and handling costs, are recorded in Selling, general and administrative expenses in the Consolidated Income Statement.

U Earnings per share

Earnings per share are calculated by dividing the income attributable to the shareholders' equity by the monthly weighted average number of common shares outstanding during the period.

There are no dilutive potential ordinary shares.

V Financial instruments

Non-derivative financial instruments comprise investments in financial debt instruments and equity, time deposits, trade and other receivables, cash and cash equivalents, borrowings and trade and other payables.

The Company classifies its financial instruments according to the following measurement categories:

  • those to be measured subsequently at fair value (either through OCI or through profit or loss), and
  • those to be measured at amortised cost.

The classification depends on the Company's business model for managing the financial assets and contractual terms of the cash flows.

Financial assets are recognized on their settlement date. Financial assets are derecognized when the rights to receive cash flows from the financial assets have expired or have been transferred and the Company has transferred substantially all the risks and rewards of ownership.

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

Subsequent measurement of debt instruments depends on the Company's business model for managing the asset and the cash flow characteristics of the asset. There are three measurement categories into which the Company classifies its debt instruments:

Amortized Cost: Assets that are held for collection of contractual cash flows where those cash flows represent solely payments of principal and interest. Interest income from these financial assets is included in finance income using the effective interest rate method.

Exchange gains and losses and impairments related to the financial assets are immediately recognized in the Consolidated Income Statement.

Fair value through other comprehensive income: Assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets' cash flows represent solely payments of principal and interest. Interest income from these financial assets is included in finance income using the effective interest rate method. Unrealized gains or losses are recorded as a fair value adjustment in the Consolidated Statement of Comprehensive Income and transferred to the Consolidated Income Statement when the financial asset is sold.

Fair value through profit and loss: Assets that do not meet the criteria for amortized cost or FVOCI. Changes in fair value of financial instruments at FVPL are immediately recognized in the Consolidated Income Statement.

Equity instruments are subsequently measured at fair value.

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

III. FINANCIAL RISK MANAGEMENT

The multinational nature of Tenaris's operations and customer base exposes the Company to a variety of risks, mainly related to market risks (including the effects of changes in foreign currency exchange rates and interest rates), credit risk and capital market risk. In order to manage the volatility related to these exposures, management evaluates exposures on a consolidated basis, taking advantage of exposure netting. The Company or its subsidiaries may then enter into various derivative transactions in order to prevent potential adverse impacts on Tenaris's financial performance. Such derivative transactions are executed in accordance with internal policies and hedging practices.

A. Financial risk factors

(i) Capital risk management

Tenaris seeks to maintain a low debt to total equity ratio considering the industry and the markets where it operates. The year-end ratio of debt to total equity (where "debt" comprises financial borrowings and "total equity" is the sum of financial borrowings and equity) is 0.03 as of December 31, 2023 and 0.05 as of December 31, 2022. The Company does not have to comply with regulatory capital adequacy requirements.

(ii) Foreign exchange risk

Tenaris manufactures and sells its products in a number of countries throughout the world and consequently is exposed to foreign exchange rate risk. Since the Company's functional currency is the U.S. dollar the purpose of Tenaris's foreign currency hedging program is mainly to reduce the risk caused by changes in the exchange rates of other currencies against the U.S. dollar.

Tenaris's exposure to currency fluctuations is reviewed on a periodic and consolidated basis. A number of derivative transactions are performed in order to achieve an efficient coverage in the absence of operative or natural hedges. Almost all of these transactions are forward exchange rates contracts. See note 26 to these Consolidated Financial Statements.

Tenaris does not enter into derivative financial instruments for trading or other speculative purposes, other than nonmaterial investments in structured products.

In the case of subsidiaries with functional currencies other than the U.S. dollar, the results of hedging activities, reported in accordance with IFRS, may not reflect entirely the management's assessment of its foreign exchange risk hedging program. Intercompany balances between Tenaris's subsidiaries may generate financial gains (losses) to the extent that functional currencies differ.

The value of Tenaris's financial assets and liabilities is subject to changes arising from the variation of foreign currency exchange rates. The following table provides a breakdown of Tenaris's main financial assets and liabilities (including foreign exchange derivative contracts) which impact the Company's profit and loss as of December 31, 2023 and 2022.

All amounts Long / (Short) in thousands of U.S. dollars As of December 31,
Currency Exposure / Functional currency 2023 2022
Argentine Peso / U.S. dollar (134,716) (126,739)
Euro / U.S. dollar (203,608) (42,458)
Saudi Arabian Riyal / U.S. dollar (181,931) (74,183)

The main relevant exposures correspond to:

▪ Argentine Peso / U.S. dollar

As of December 31, 2023 and 2022 consisting primarily of Argentine Peso-denominated financial, trade, social and fiscal payables at certain Argentine subsidiaries whose functional currency is the U.S. dollar. A change of 1% in the ARS/USD exchange rate would have generated a pre-tax gain / loss of \$1.3 million and \$1.3 million as of December 31, 2023 and 2022 respectively.

▪ Euro / U.S. dollar

As of December 31, 2023 and 2022 consisting primarily of Euro-denominated intercompany liabilities at certain subsidiaries whose functional currency is the U.S. dollar. A change of 1% in the EUR/USD exchange rate would have generated a pre-tax gain / loss of \$2.0 million and \$0.4 million as of December 31, 2023 and 2022, respectively, which would have been to a large extent offset by changes in currency translation adjustment included in Tenaris's net equity position.

▪ Saudi Arabian Riyal / U. S. dollar

As of December 31, 2023 and 2022 consisting primarily of Saudi Arabian Riyal-denominated financial and trade payables. The Saudi Arabian Riyal is tied to the U.S. dollar.

Considering the balances held as of December 31, 2023 on financial assets and liabilities exposed to foreign exchange rate fluctuations, Tenaris estimates that the impact of a simultaneous 1% favorable / unfavorable movement in the levels of foreign currencies exchange rates relative to the U.S. dollar, would be a pre-tax gain / loss of \$6.7 million (including a loss / gain of \$2.3 million due to foreign exchange derivative contracts), which would be partially offset by changes to Tenaris's net equity position of \$1.1 million. For balances held as of December 31, 2022, a simultaneous 1% favorable / unfavorable movement in the foreign currencies exchange rates relative to the U.S. dollar, would have generated a pretax gain / loss of \$4.0 million (including a loss / gain of \$0.2 million due to foreign exchange derivative contracts), which would have been partially offset by changes to Tenaris's net equity position of \$0.9 million.

Tenaris based its foreign exchange sensitivity analysis on a 1% variance for information purposes only, enabling the analysis to any particular variance.

(iii) Interest rate risk

Tenaris is subject to interest rate risk on its investment portfolio and its debt. The Company uses a mix of variable and fixed rate debt in combination with its investment portfolio strategy. The Company may choose to enter into foreign exchange derivative contracts and / or interest rate swaps to mitigate the exposure to changes in the interest rates.

The following table summarizes the proportions of variable-rate and fixed-rate debt as of each year end.

As of December 31,
2023 2022
In thousands of U.S. dollars % In thousands of U.S. dollars %
Fixed rate (*) 294,946 51% 497,889 68%
Variable rate 288,491 49% 230,873 32%
Total 583,437 728,762

(*) Out of the \$294.9 million fixed rate borrowings, \$271.1 million are short-term.

The Company estimates that, if market interest rates applicable to Tenaris's borrowings had been 100 basis points higher, then the additional pre-tax loss would have been \$6.4 million in 2023 and \$5.3 million in 2022.

Tenaris based its interest rate sensitivity analysis on a 100 basis points variance for information purposes only, enabling the analysis to any particular variance.

(iv) Credit risk

Credit risk arises from cash and cash equivalents, deposits with banks and financial institutions, as well as credit exposures to customers, including outstanding receivables and committed transactions. The Company also actively monitors the creditworthiness of its treasury, derivative and insurance counterparties in order to minimize its credit risk.

No single customer comprised more than 10% of Tenaris's net sales in 2023, 2022 and 2021.

Tenaris maintains a strong, longstanding relationship with Petróleos Mexicanos ("Pemex"), one of the world's largest crude oil and condensates producers and one of its largest customers. Over the past several months, Pemex has delayed payments beyond the agreed-upon due dates, resulting in Tenaris having a significant credit exposure to Pemex, which represented approximately 20% of the Company's overall credit exposure as of December 31, 2023. The Company has not historically had any material write-offs due to uncollectible accounts receivable relating to this customer. Although the parties are in continuous conversations and Pemex is making partial payments on a periodic basis, at this stage the Company cannot predict whether or not its exposure to Pemex will be reduced, or the timing for any such reduction.

Tenaris's credit policies related to sales of products and services are designed to identify customers with acceptable credit history and to allow Tenaris to require the use of credit insurance, letters of credit and other instruments designed to minimize credit risks whenever deemed necessary. Tenaris maintains allowances for impairment for potential credit losses. See section II.K.

As of December 31, 2023, trade receivables amounted to \$2,480.9 million. Trade receivables had guarantees under credit insurance of \$212.7 million, letter of credit and other bank guarantees of \$48.4 million. Overdue trade receivables amounted to \$679.6 million, overdue guaranteed trade receivables amounted to \$24.4 million; and the allowance for doubtful accounts amounted to \$49.0 million.

As of December 31, 2022, trade receivables amounted to \$2,493.9 million. Trade receivables had guarantees under credit insurance of \$231.2 million, letter of credit and other bank guarantees of \$34.7 million. Overdue trade receivables amounted to \$544.9 million, overdue guaranteed trade receivables amounted to \$28.1 million; and the allowance for doubtful accounts amounted to \$45.5 million.

Management believes that both the allowance for doubtful accounts and the existing guarantees are sufficient to cover doubtful trade receivables.

(v) Counterparty risk

Tenaris has investment guidelines with specific parameters to limit issuer risk on marketable securities. Counterparties for derivatives and cash transactions are limited to high credit quality financial institutions, normally investment grade.

Approximately 91% of Tenaris's liquid financial assets corresponded to Investment Grade-rated instruments as of December 31, 2023, in comparison with approximately 80% as of December 31, 2022.

(vi) Liquidity risk

Tenaris's financing strategy aims to maintain adequate financial resources and access to additional liquidity. During 2023, Tenaris has counted on cash flows from operations as well as additional bank financing to fund its transactions.

Management maintains sufficient cash and marketable securities to finance normal operations and believes that Tenaris also has appropriate access to market for short-term working capital needs.

Liquid financial assets as a whole (comprising cash and cash equivalents and other investments) were 19% and 9% of total assets at the end of 2023 and 2022, respectively.

Tenaris has a conservative approach to the management of its liquidity, which consists of i) cash and cash equivalents (cash in banks, liquidity funds and investments with a maturity of less than three months at the date of purchase), and ii) other investments (fixed income securities, time deposits, and fund investments).

Tenaris holds primarily investments in money market funds and variable or fixed-rate securities from investment grade issuers.

Tenaris holds its investments primarily in U.S. dollars. As of December 31, 2023 and 2022, U.S. dollar denominated liquid assets plus investments denominated in other currencies hedged to the U.S. dollar represented approximately 94% and 87% of total liquid financial assets, respectively.

(vii) Commodity price risk

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

B. Category of financial instruments and classification within the fair value hierarchy

As mentioned in note II.V, the Company classifies its financial instruments in the following measurement categories: amortized cost, fair value through other comprehensive income and fair value through profit and loss. For financial instruments that are measured in the statement of financial position at fair value, IFRS 13, "Fair value measurement" requires a disclosure of fair value measurements by level according to the following fair value measurement hierarchy:

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices).

Level 3: Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs).

The following tables present the financial instruments by category and levels as of December 31, 2023 and 2022.

(*) Includes balances related to interest in Venezuelan companies. See note 35 to these Consolidated Financial Statements.

There were no transfers between levels during the year.

The fair value of financial instruments traded in active markets is based on quoted market prices at the reporting date. A market is regarded as active if quoted prices are readily and regularly available from an exchange, dealer, broker, industry group, pricing service, or regulatory agency, and those prices represent actual and regularly occurring market transactions on an arm's length basis. The quoted market price used for financial assets held by Tenaris is the current bid price. These instruments are included in Level 1 and comprise primarily corporate and sovereign debt securities.

The fair value of financial instruments that are not traded in an active market (such as certain debt securities, certificates of deposits with original maturity of more than three months, forward and interest rate derivative instruments) is determined by using valuation techniques which maximize the use of observable market data when available and rely as little as possible on entity specific estimates. If all significant inputs required to value an instrument are observable, the instrument is included in Level 2. Tenaris values its assets and liabilities included in this level using bid prices, interest rate curves, broker quotations, current exchange rates, forward rates and implied volatilities obtained from market contributors as of the valuation date.

If one or more of the significant inputs are not based on observable market data, the instruments are included in Level 3. Tenaris values its assets and liabilities in this level using observable market inputs and management assumptions which reflect the Company's best estimate on how market participants would price the asset or liability at measurement date.

The following table presents the changes in Level 3 assets:

Year ended December 31,
2023 2022
At the beginning of the year 54,987 56,294
Decrease (*) (47,467) (1,126)

At the end of the year 7,411 54,987

(*) For 2023, related to the sale of Venezuela awards. For more information see notes 6 and 35.

C. Fair value estimation

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

The fair values of quoted investments are generally based on current bid prices. If the market for a financial asset is not active or no market is available, fair values are established using standard valuation techniques.

The fair value of all outstanding derivatives is determined using specific pricing models that include inputs that are observable in the market or can be derived from or corroborated by observable data. The fair value of forward foreign exchange contracts is calculated as the net present value of the estimated future cash flows in each currency, based on observable yield curves, converted into U.S. dollars at the spot rate of the valuation date.

Borrowings are classified under other financial liabilities and measured at their amortized cost. Tenaris estimates that the fair value of its main financial liabilities is approximately 99.8% and 99.2% of its carrying amount (including interests accrued) in 2023 and 2022 respectively. Fair values were calculated using standard valuation techniques for floating rate instruments and comparable market rates for discounting cash flows.

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

D. Accounting for derivative financial instruments and hedging activities

Derivative financial instruments are initially recognized in the statement of financial position at fair value through profit and loss on each date a derivative contract is entered into and are subsequently remeasured at fair value. Specific tools are used for calculation of each instrument's fair value and these tools are tested for consistency on a monthly basis. Market rates are used for all pricing operations. These include exchange rates, deposit rates and other discount rates matching the nature of each underlying risk.

As a general rule, Tenaris recognizes the full amount related to the change in fair value of derivative financial instruments in Financial Results in the Consolidated Income Statement.

Tenaris designates certain derivatives as hedges of particular risks associated with recognized assets or liabilities or highly probable forecast transactions. These transactions are classified as cash flow hedges. The effective portion of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in equity. Amounts accumulated in equity are then recognized in the income statement in the same period as the offsetting losses and gains on the hedged item. The gain or loss relating to the ineffective portion is recognized immediately in the income statement. The fair value of Tenaris's derivative financial instruments (assets or liabilities) continues to be reflected in the statement of financial position.

For transactions designated and qualifying for hedge accounting, Tenaris documents at the inception of the transaction the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. Tenaris also documents its assessment on an ongoing basis, of whether the hedging instruments are highly effective in offsetting changes in the fair value or cash flow of hedged items. At December 31, 2023 and 2022, the effective portion of designated cash flow hedges which is included in Other Reserves in equity amounted to \$8.1 million credit and \$13.1 million credit respectively.

The fair values of various derivative instruments used for hedging purposes and the movements of the hedging reserve included within Other Reserves in equity are disclosed in note 26 to these Consolidated Financial Statements.

Transactions between segments, which were eliminated in consolidation, are mainly related to sales of scrap, energy, surplus raw materials and others from the Other segment to the Tubes segment for \$98.5 million, \$77.9 million and \$45.6 million in 2023, 2022 and 2021, respectively.

There are no material differences between IFRS and management view in total revenues and by reportable segments.

The differences between operating income under IFRS view and the management view are mainly related to the cost of goods sold, reflecting the effect of raw materials prices increases on the valuation of the replacement cost considered for management view compared to IFRS cost calculated at historical cost on a FIFO basis, and other minor timing differences.

The main difference in Other operating income (expenses), net, for the year ended December 31, 2022, is attributable to the effect of the reclassification of the currency translation adjustment reserve related to NKK Tubes' definitive cease of operations, not impacting the management view.

In addition to the amounts reconciled above, the main differences in net income arise from the impact of functional currencies on financial result, deferred income taxes as well as the result of investment in non-consolidated companies.

5 Impairment charge

Tenaris's main source of revenue is the sale of products and services to the oil and gas industry, and the level of such sales is sensitive to international oil and gas prices and their impact on drilling activities.

The Company conducts regular assessments of the carrying values of its assets. The recoverable value is based on the value in use. The main key assumptions used in estimating the value in use are discount rate, growth rate and competitive, economic and regulatory factors applied to determine cash flow projections, such as oil and gas prices, average number of active oil and gas drilling rigs (rig count) and raw material costs.

For purposes of assessing key assumptions, to estimate discounted future cash flows, the Company uses external sources of information and management judgment based on past experience and expectations. Management has determined the value of each of the key assumptions as follows:

  • Discount rate: based on the applicable weighted average cost of capital ("WACC"), which is considered to be a good indicator of capital cost, taking into account the industry, country and size of the business. For each CGU where assets are allocated, a specific WACC was determined.

  • Growth rate: considers mainly the inflation impact on prices and costs, the long-term evolution of the oil and gas industry, the higher demand to offset depletion of existing fields and the Company's expected market penetration. In 2023, a nominal growth rate of 2% was considered.

  • Oil and gas prices: based on industry analysts' reports and management's expectations of market development.

  • Rig count: based on information published by Baker Hughes and management's expectations.

  • Raw material costs: based on industry analysts' reports and management's expectations.

Considering that the recoverable amount of the cash-generating units obtained in prior years' tests and that the assets and liabilities making up those units have not changed significantly, nor the key assumptions mentioned above, the Company concluded that impairment tests for previous years are still valid as of the end of the reporting period. In addition, the Company has considered the impact of updating the main discount rates, applying rates in a range between 12.5% and 21.4% for the CGUs under analysis. Based on the facts mentioned above, the Company concluded that no impairment charge shall be recognized for the year 2023.

In December 2022, in the presence of impairment indicators, the Company conducted impairment tests and reviewed the values of certain idle assets in its subsidiaries. The aforementioned analysis resulted in impairment charges of \$76.7 million, allocated in \$63.1 million to the Tubes segment and \$13.6 million to the Other segment. The main discount rates used were in a range between 13.4% and 20.2%. In 2022, a nominal growth rate of 2% was considered.

In December 2021, as a result of the expected termination of the NKKTubes joint venture, which at the time represented an impairment indicator for its assets, an impairment test was conducted, resulting in a charge of \$57 million that totally reduced the carrying amounts of property, plant and equipment and intangible assets. The total amount was allocated to the Tubes segment. The main discount rates used were in a range between 10.9% and 18.8%. In 2021, a nominal growth rate of 2% was considered.

No current tax impacts have arisen in the current Consolidated Financial Statements as of December 31, 2023, due to the application of Pillar Two rules, as they will be applicable as from 2024 in jurisdictions relevant for the Company.

In addition, the Company has applied the exception prescribed by the amendments to IAS 12, and therefore it has not recognized any deferred tax impact from the Pillar Two application.

The Company is in the process of assessing its exposure to the Pillar Two legislation and testing its situation under the OECD transitional safe harbour rules and expects no major impacts in relation to top-up tax due to the application of one or more of the transitional safe harbour rules.

Due to the complexities in applying the legislation and calculating GloBE income, the quantitative impact of the enacted legislation is not yet reasonably estimable.

The tax on Tenaris's income before tax differs from the theoretical amount that would arise using the tax rate in each country as follows:

Year ended December 31,
2023 2022 2021
Income before income tax 4,632,789 3,165,937 1,242,766
Less impairment charges (non-deductible) - - 57,075
Income before income tax without impairment charges 4,632,789 3,165,937 1,299,841
Tax calculated at the tax rate in each country (1,127,428) (705,727) (209,765)
Effect of currency translation on tax base (346,573) (187,186) (76,043)
Changes in the tax rates 1,535 (3,422) (29,881)
Utilization of previously unrecognized tax losses 787 29,560 966
Tax revaluation, withholding tax and others 796,723 249,539 125,275
Tax charges (674,956) (617,236) (189,448)

Effect of currency translation on tax base: Tenaris applies the liability method to recognize deferred income tax on temporary differences between the tax bases of assets / liabilities and their carrying amounts in the financial statements. By application of this method, Tenaris recognizes gains and losses on deferred income tax due to the effect of the change in the value on the tax bases in subsidiaries (mainly Argentina and Mexico), which have a functional currency different than their local currency. These gains and losses are required by IFRS even though the revalued / devalued tax bases of the relevant assets will not result in any deduction / obligation for tax purposes in future periods.

Changes in the tax rates: For the year 2021, includes mainly the effect of the increase in the corporate income tax rate in Argentina from 25% to 35%.

Tax revaluation, withholding tax and others: Includes a net tax income of \$349.0 million, \$250.4 million and \$113.2 million for 2023, 2022 and 2021 respectively related to the tax revaluation regimes in Argentina and Mexico. It also includes a charge of \$164.3 million, \$21.0 million and \$22.6 million for 2023, 2022 and 2021 respectively related to withholding taxes for intra-group international operations. Additionally, it includes \$550.3 million tax income for 2023 related to the recognition deferred tax assets due to previous years' tax losses carried forward in Luxembourg. For more information see note 22.

c) Techgen

Techgen is a Mexican company that operates a natural gas-fired combined cycle electric power plant in the Pesquería area of the State of Nuevo León, Mexico, with a power capacity of 900 megawatts. As of December 31, 2023, Tenaris held 22% of Techgen's share capital, and its affiliates, Ternium and Tecpetrol (both controlled by San Faustin), beneficially owned 48% and 30% respectively. As of December 31, 2023, the carrying value of Tenaris's ownership stake in Techgen was approximately \$53.6 million.

Techgen entered into certain transportation capacity agreements and an agreement for the purchase of clean energy certificates. As of December 31, 2023, Tenaris's exposure under these agreements amounted to \$39.4 million and \$16.9 million respectively.

Techgen's sponsors granted certain subordinated loans to Techgen. As of December 31, 2023, the aggregate outstanding principal amount under these subordinated loans was \$281.3 million, of which \$61.9 million correspond to Tenaris's contribution.

On February 13, 2019, Techgen entered into a \$640 million syndicated loan agreement with several banks to refinance an existing loan, resulting in the release of certain corporate guarantees previously issued by Techgen's shareholders to secure the replaced facility.

The existing syndicated loan agreement is "non-recourse" on the sponsors. Techgen's obligations thereunder are guaranteed by a Mexican security trust (covering shares, assets, accounts and contract rights), account pledges and certain direct agreements –customary for these type of transactions–. The commercial terms and conditions governing the purchase by the Company's Mexican subsidiary, Tamsa, of 22% of the energy generated by Techgen remain substantially unchanged.

Under the loan agreement, Techgen is committed to maintain a debt service reserve account covering debt service becoming due during two consecutive quarters; such account is funded by stand-by letters of credit issued for the account of Techgen's sponsors in proportion to their respective participations in Techgen. Accordingly, the Company applied for stand-by letters of credit covering 22% of the debt service coverage ratio, which as of December 31, 2023, amounted to \$10.9 million.

d) GPC

GPC is a joint venture established in 2010 and located in Jubail, Saudi Arabia, which manufactures LSAW pipes. Until May 16, 2023, Tenaris, through its subsidiary SSPC, owned 35% of the share capital of GPC and, accordingly, GPC was a non-consolidated company. On May 17, 2023, SSPC acquired an additional 22.3% interest in GPC reaching a participation of 57.3%. The Company consolidates GPC's balances and results of operations as from May 17, 2023. For more information on GPC acquisition and its accounting treatment see note 34 "Business Combinations - Global Pipe Company acquisition".

Deferred tax assets related to tax losses of Tenaris subsidiaries are recognized to the extent it is probable that future taxable profits will be available, against which such losses can be utilized. The utilization of such tax losses may also be restricted by the nature of the profit, expiration dates and / or potential limitations on their yearly consumption. In determining the amount of deferred taxes to be recognized, Tenaris considered existing evidence, both positive and negative, including the historical taxable profits and the projections of future taxable profits prepared by management to assess the probability that the deferred tax assets will be realized. Management applies significant judgment in assessing the likelihood that future taxable profits will be available.

Deferred tax assets related to tax losses as of the end of 2023 include \$550.3 million recognized in its Luxembourg subsidiary mainly due to impairment charges over certain undertakings in the past years. Under the Luxembourg tax law, tax losses generated before 2017 can be carried forward indefinitely and are not subject to any yearly consumption limitation. Losses incurred as from 2017 may be carried forward for a maximum of 17 years.

Tenaris has concluded as of end 2023 that it is probable that sufficient future taxable profits will be generated by business activities to be carried out by its Luxembourg subsidiary, against which the above-mentioned tax losses could be utilized prior to their expiration.

Deferred tax assets related to tax losses also include \$77.9 million related to U.S. subsidiaries mainly due to the recognition of accelerated fiscal depreciations, as well as the amounts related to the acquisition of IPSCO in 2020. Tenaris has concluded that these deferred tax assets will be recoverable based on the business plans and budgets.

Approximately 99% of the recognized tax losses have an expiration date in more than 5 years or do not expire.

As of December 31, 2023, the net unrecognized deferred tax assets amounted to \$3,130.0 million. Approximately 99% of the unrecognized tax losses have an expiration date in more than 5 years or do not expire.

The estimated recovery analysis of deferred tax assets and settlement of deferred tax liabilities, which takes into consideration management assumptions and estimates, is as follows:

Year ended December 31,
2023 2022
Deferred tax assets to be recovered after 12 months (655,415) (171,717)
Deferred tax liabilities to be settled after 12 months 689,976 688,124

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

Year ended December 31,
2023 2022
Deferred tax assets (789,615) (208,870)

The actuarial assumptions for the most relevant plans were as follows:

Year ended December 31,
2023 2022
Discount rate 3% - 7% 4% - 7%
Rate of compensation increase 2% - 5% 2% - 3%

As of December 31, 2023, an increase / (decrease) of 1% in the discount rate assumption of the main plans would have generated a (decrease) / increase on the defined benefit obligation of \$5.6 million and \$5.0 million respectively, and an increase / (decrease) of 1% in the rate of compensation assumption of the main plans would have generated an increase / (decrease) impact on the defined benefit obligation of \$2.7 million and \$2.9 million respectively. The above sensitivity analyses are based on a change in discount rate and rate of compensation while holding all other assumptions constant. In practice, this is unlikely to occur, and changes in some of the assumptions may be correlated.

▪ Funded

The amounts recognized in the statement of financial position for the current annual period and the previous annual period are as follows:

Year ended December 31,
2023 2022
Present value of funded obligations 123,234 116,617
Fair value of plan assets (134,052) (126,842)
Asset (*) (10,818) (10,225)

(*) In 2023 and 2022, \$15.8 million and \$15.3 million corresponding to plans with surplus balances that were reclassified within other non-current assets, respectively, consequently the net post-employment benefits funded exposed as liabilities amounted to \$5.0 million and \$5.1 million respectively.

The movement in the present value of funded obligations is as follows:

Year ended December 31,
2023 2022
At the beginning of the year 116,617 159,528
Translation differences 1,940 (6,635)
Current service cost - 154

Benefits paid (8,459) (10,374)
Other 571 -
At the end of the year 123,234 116,617

(*) For 2023 a loss of \$0.9 million is attributable to demographic assumptions and a loss of \$1.3 million to financial assumptions. For 2022 a gain of \$4.8 million is attributable to demographic assumptions and a gain of \$25.6 million to financial assumptions.

The major categories of plan assets as a percentage of total plan assets are as follows:

Year ended December 31,
2023 2022
Equity instruments 18.0% 28.8%
Debt instruments 32.5% 67.2%
Others 49.3% 4.0%

The actuarial assumptions for the most relevant plans were as follows:

Year ended December 31,
2023 2022
Discount rate 5% - 5% 3% - 5%
Rate of compensation increase 0% - 3% 0% - 3%

The expected return on plan assets is determined by considering the expected returns available on the assets underlying the current investment policy. Expected return on plan assets is determined based on long-term, prospective rates of return as of the end of the reporting period.

As of December 31, 2023, an increase / (decrease) of 1% in the discount rate assumption of the main plans would have generated a (decrease) / increase on the defined benefit obligation of \$11.7 million and \$9.9 million respectively, and an increase / (decrease) of 1% in the compensation rate assumption of the main plans would have generated an increase / (decrease) on the defined benefit obligation of \$0.7 million and \$0.8 million respectively. The above sensitivity analyses are based on a change in discount rate and rate of compensation while holding all other assumptions constant. In practice, this is unlikely to occur, and changes in some of the assumptions may be correlated.

The expected employer contributions for the year 2024 are not material.

The methods and types of assumptions used in preparing the sensitivity analyses did not change compared to the previous period.

27 Contingencies, commitments and restrictions on the distribution of profits

(i) Contingencies

Tenaris is from time to time subject to various claims, lawsuits and other legal proceedings, including customer, employee, tax and environmental-related claims, in which third parties are seeking payment for alleged damages, reimbursement for losses, or indemnity. Management, with the assistance of legal counsel, periodically reviews the status of each significant matter and assesses potential financial exposure.

Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are subject to substantial uncertainties and, therefore, the probability of loss and an estimation of damages are difficult to ascertain. Accordingly, with respect to a large portion of such claims, lawsuits and other legal proceedings, the Company is unable to make a reliable estimate of the expected financial effect that will result from ultimate resolution of the proceeding. In those cases, the Company has not accrued a provision for the potential outcome of these cases.

If a potential loss from a claim, lawsuit or other proceeding is considered probable and the amount can be reasonably estimated, a provision is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be incurred based on information available to management as of the date of preparation of the financial statements and take into consideration litigation and settlement strategies. In a limited number of ongoing cases, the Company was able to make a reliable estimate of the expected loss or range of probable loss and, depending on the likelihood of occurrence, in some of such cases has accrued a provision for such loss but believes that publication of this information on a case-by-case basis would seriously prejudice the Tenaris's position in the ongoing legal proceedings or in any related settlement discussions. Accordingly, in these cases, the Company has disclosed information with respect to the nature of the contingency but has not disclosed its estimate of the range of potential loss.

The Company believes that the aggregate provisions recorded for potential losses in these Consolidated Financial Statements are adequate based upon currently available information. However, if management's estimates prove incorrect, current reserves could be inadequate and the Company could incur a charge to earnings which could have a material adverse effect on its results of operations, financial condition, net worth and cash flows.

Below is a summary description of Tenaris's material legal proceedings which are outstanding as of the date of these Consolidated Financial Statements. In addition, the Company is subject to other legal proceedings, none of which is believed to be material.

▪ CSN claims relating to the January 2012 acquisition of Usiminas

In 2013, the Company was notified of a lawsuit filed in Brazil by Companhia Siderúrgica Nacional ("CSN"), and various entities affiliated with CSN against the Company's Brazilian subsidiary Confab and three subsidiaries of Ternium, all of which compose the T/T Group under the Usiminas shareholders agreement. The entities named in the CSN lawsuit had acquired a participation in Usiminas in January 2012. The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition, or BRL 28.8, and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to Usiminas' control group. Confab's share in the offer would be 17.9%.

On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals maintained the understanding of the first instance court. On August 18, 2017, CSN filed an appeal to the Superior Court of Justice ("SCJ") seeking the review and reversal of the decision issued by the Court of Appeals. On September 10, 2019, the SCJ declared CSN's appeal admissible. On March 7, 2023, the SCJ, by majority vote, rejected CSN's appeal. CSN made several submissions in connection with the SCJ decision, including a motion for clarification that challenged the merits of the SCJ decision. Decisions at the SCJ are adopted by majority vote and, at the date of these financial statements, voting at the SCJ with respect to the motion for clarification is ongoing. At an October 17, 2023 session, two justices voted in favor of remanding the case to the first instance for it to be retried following production and assessment of the new evidence, and two justices voted, without requiring any further evidence, in favor of granting CSN's motion for clarification and reversing the March 7, 2023 decision that rejected CSN's appeal; because the fifth member of SCJ excused himself from voting, a justice from another panel at the SCJ will be summoned to produce the tie-breaking vote. There are no specified deadlines for voting to be resumed or the SCJ decision to be issued. In any event, either party may appeal against a SCJ decision.

According to the views of the two justices that voted in favor of CSN's motion, Confab and the other members of the T/T Group should be ordered to pay to CSN an indemnification amount equal to the difference between the price paid by the T/T Group in its acquisition and the market value of the Usiminas shares at signing, plus monetary adjustment and interest (at a rate of 1% per month) through the date of payment, plus legal costs equal to 10% of the compensation payable to CSN, with CSN retaining ownership of the Usiminas ordinary shares it currently owns. If that unprecedented view were to prevail, and depending on how the indemnification is calculated by other courts, as of the date of these financial statements the potential aggregate indemnification payable by Confab could reach up to BRL900.4 million (approximately \$186.0 million at the BRL/\$ rate as of such date).

The Company continues to believe that all of CSN's claims and allegations are groundless and without merit, as confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator in February 2012 and December 2016, the first and second instance court decisions and the March 7, 2023 SCJ decision referred to above. Notwithstanding the foregoing, in light of the votes already issued by two members of the SCJ on CSN's motion for clarification, the Company cannot predict the ultimate resolution on the matter.

▪ Veracel celulose accident litigation

On September 21, 2007, an accident occurred in the premises of Veracel Celulose S.A. ("Veracel") in connection with a rupture in one of the tanks used in an evaporation system manufactured by Confab. The Veracel accident allegedly resulted in material damages to Veracel. Itaú Seguros S.A. ("Itaú"), Veracel's insurer at the time of the Veracel accident and then replaced by Chubb Seguros Brasil S/A ("Chubb"), initiated a lawsuit against Confab seeking reimbursement of damages paid to Veracel in connection with the Veracel accident. Veracel initiated a second lawsuit against Confab seeking reimbursement of the amount paid as insurance deductible with respect to the Veracel accident and other amounts not covered by insurance. Itaú and Veracel claimed that the Veracel accident was caused by failures and defects attributable to the evaporation system manufactured by Confab. Confab believes that the Veracel accident was caused by the improper handling by Veracel's personnel of the equipment supplied by Confab in violation of Confab's instructions. The two lawsuits were consolidated and are considered by the 6th Civil Court of São Caetano do Sul. However, each lawsuit will be adjudicated separately.

On September 28, 2018, Confab and Chubb entered into a settlement agreement pursuant to which on October 9, 2018, Confab paid an amount of approximately \$3.5 million to Chubb, without assuming any liability for the accident or the claim.

On October 10, 2018, Confab was notified that the court had issued rulings for both lawsuits. Both decisions were unfavorable to Confab:

  • With respect to Chubb's claim, the court subsequently homologated the above-mentioned settlement and, accordingly, the claim was finalized.
  • With respect to Veracel's claim, Confab was ordered to pay the insurance deductible and other concepts not covered by insurance, currently estimated to amount to BRL100.6 million (approximately \$20.8 million) including interest, fees and expenses. Both parties filed motions for clarification against the court's decision, which were partially granted. Although the contract between Confab and Veracel expressly provided that Confab would not be liable for damages arising from lost profits, the court award would appear to include BRL86.4 million (approximately \$17.8 million) of damages arising therefrom. Confab has additional defense arguments in respect of a claim for lost profits. On December 18, 2018, Confab filed an appeal against the first instance court decision, and on April 30, 2019, Veracel filed its response to the appeal. In June 2022, the court resolved that it lacked jurisdiction to decide on the appeal, which was re-allocated to another court. The parties are currently waiting for the trial of the appeal to be scheduled. At this stage the Company cannot predict the outcome of the claim or the amount or range of loss in case of an unfavorable outcome.

▪ Petrobras-related proceedings and claims

Upon learning that Brazilian, Italian and Swiss authorities were investigating whether certain payments were made prior to 2014 from accounts of entities presumably associated with affiliates of the Company to accounts allegedly linked to individuals related to Petróleo Brasileiro S.A. ("Petrobras") and whether any such payments were intended to benefit the Company's Brazilian subsidiary Confab, the Audit Committee of the Company's Board of Directors engaged external counsel in connection with the Company's review of these matters. In addition, the Company voluntarily notified the U.S. Securities and Exchange Commission ("SEC") and the U.S. Department of Justice ("DOJ") in October 2016. The Company conducted, with the assistance of external counsel, an internal investigation and found no evidence corroborating any involvement by the Company or its directors, officers or employees in respect of improper payments. An internal investigation commissioned by Petrobras also found no evidence that Confab obtained any unfair commercial benefit or advantage from Petrobras in return for payments, including improperly obtained contracts. On June 2, 2022, the Company resolved the investigation by the SEC, and the DOJ informed that it had closed its parallel inquiry without taking action. Under the settlement with the SEC, the Company neither admits nor denies the SEC's findings and on June 24, 2022, paid \$53.1 million in disgorgement and prejudgment interest and \$25 million for a civil penalty to conclude the matter.

In July 2019, the Company learned that the public prosecutors' office of Milan, Italy, had completed a preliminary investigation into the same alleged payments and had included in the investigation, among other persons, the Company's Chairman and Chief Executive Officer, two other board members, Gianfelice Rocca and Roberto Bonatti, and the Company's controlling shareholder, San Faustin. The Company is not a party to the proceedings. On March 22, 2022, upon completion of the evidentiary phase of the trial, the acting prosecutor requested the first-instance court in Milan in charge of the case to impose sanctions on our Chairman and Chief Executive Officer, on the other two board members, and on San Faustin. The Company's outside counsel in Italy advised the Company that neither the case file nor the prosecutor's request contain or identify any evidence of involvement in, or knowledge of, the alleged wrongdoing by any of the three directors. On May 26, 2022, the first-instance court dismissed the case brought by the public prosecutor against the defendants for lack of jurisdiction and stated that the criminal proceeding should not have been initiated. On October 7, 2022, the public prosecutor filed an appeal against the first-instance court's decision. The first hearing with respect to the appeal is scheduled to be held on February 22, 2024.

In June 2020, the Brazilian public prosecutors' office requested the indictment of several individuals, including three executives or former executives of Confab and a former agent of Confab, charging them with the alleged crimes of corruption in relation to contracts executed between 2007 and 2010, and money laundering in relation to payments between 2009 and 2013. These criminal proceedings are underway. Neither the Company nor Confab is a party to these criminal proceedings.

In addition, Petrobras and the Brazilian public prosecutors filed civil claims for damages against, among others, Confab and the Confab executives named in the criminal proceedings referred to above. Confab became aware of these civil claims in September 2022. As of December 31, 2023, the aggregate amount of these claims was estimated at BRL322.2 million (or approximately \$66.6 million). The plaintiffs also seek that Confab be prohibited from contracting with, or receiving benefits or exemptions from, the Brazilian state for an unspecified term. Confab believes these claims do not address either the defense arguments or the evidence available to the plaintiffs in Brazil and presented in other jurisdictions and is vigorously contesting them. At this stage, the Company cannot predict the outcome of these civil proceedings.

▪ Putative class actions

Following the Company's November 27, 2018, announcement that its Chairman and CEO Paolo Rocca had been included in an Argentine court investigation known as the Notebooks Case (a decision subsequently reversed by a higher court), two putative class action complaints were filed in the U.S. District Court for the Eastern District of New York. On April 29, 2019, the court consolidated the complaints into a single case, captioned "In re Tenaris S.A. Securities Litigation", and appointed lead plaintiffs and lead counsel.

On July 19, 2019, the lead plaintiffs filed an amended complaint purportedly on behalf of purchasers of Tenaris securities during the putative class period of May 1, 2014, through December 5, 2018. The individual defendants named in the complaint are Tenaris's Chairman and CEO and Tenaris's former CFO. The complaint alleges that during the class period, the Company and the individual defendants inflated the Tenaris share price by failing to disclose that the nationalization proceeds received by Ternium (in which the Company held an 11.46% stake) when Sidor was expropriated by Venezuela were received or expedited as a result of allegedly improper payments made to Argentine officials. The complaint does not specify the damages that plaintiff is seeking.

On October 9, 2020, the court granted in part and denied in part the defendants' motions to dismiss. The court partially granted and partially denied the motion to dismiss the claims against the Company and its Chairman and CEO. In addition, the court granted the motions to dismiss as to all claims against San Faustin, Techint, and Tenaris's former CFO.

On November 11, 2022, the parties filed a joint notice of settlement announcing a settlement in principle of all claims in the action, subject to finalizing the settlement agreements and court approval. The parties' agreement in principle provides that, in exchange for dismissal of the action and customary releases from class members and with no admission of liability by Tenaris or Mr. Rocca, Tenaris will pay to the class \$9.5 million (inclusive of legal fees to lead plaintiff's counsel).

On April 10, 2023, the court granted preliminary approval to the class settlement. The final settlement approval hearing was set for October 19, 2023, and on that date the court ordered that, prior to granting final settlement approval, the lead plaintiffs submit on or before March 29, 2024, an update letter advising the court of the status of the claims processing.

▪ Administrative proceeding concerning Brazilian tax credits

Confab is a party to an administrative proceeding concerning the recognition and transfer of tax credits for an amount allegedly exceeding the amount that Confab would have been entitled to recognize and / or transfer. The proceeding resulted in the imposition of a fine against Confab representing approximately 75% of the allegedly undue credits, which was appealed by Confab. On January 21, 2019, Confab was notified of an administrative decision denying Confab's appeal, thereby upholding the tax determination and the fine against Confab. On January 28, 2019, Confab challenged such administrative decision. Special appeals were filed by Confab in July 2023 and by the Brazilian General Tax Attorney ("PGFN") in September 2023. The parties are currently awaiting a resolution. In case of an unfavorable resolution, Confab may appeal before the courts. The estimated amount of this claim is BRL60.7 million (approximately \$12.5 million). At this stage, the Company cannot predict the outcome of this claim.

▪ U.S. patent infringement litigation

Tenaris Coiled Tubes, LLC ("TCT"), a U.S. subsidiary of the Company, was sued in 2017 by its competitor Global Tubing, alleging defamatory conduct by TCT and seeking a declaration that certain Global Tubing products do not infringe patents held by TCT. TCT counterclaimed that certain Global Tubing products did infringe patents held by TCT, and Global Tubing has since sought to invalidate such patents. On December 13, 2019, Global Tubing filed an amended complaint (including the Company as defendant), alleging, among other things, that TCT and the Company had misled the patent office. On March 20, 2023, the judge granted summary judgment in favor of Global Tubing, concluding that the patents at issue are unenforceable due to inequitable conduct during the patent prosecution process. TCT appealed this judgment, and Global Tubing appealed a previous ruling of the judge. Global Tubing also filed a brief seeking to recover attorneys' fees, without specifying the amount of those fees. Although it is not possible to predict the final outcome of this matter, the Company believes that any potential losses arising from this case will not be material.

▪ U.S. Antidumping Duty Investigations

On October 27, 2021, the U.S. Department of Commerce ("DOC") initiated antidumping duty investigations of oil country tubular goods ("OCTG") from Argentina, Mexico, and Russia. After the DOC issued affirmative preliminary and final antidumping determinations with respect to imports from Argentina, Mexico and Russia on October 27, 2022, the International Trade Commission ("ITC") determined that the imports under investigation caused injury to the U.S. OCTG industry. Tenaris and other parties have appealed the agency determinations from the investigation to the Court of International Trade. In addition, in response to a request from the Government of Argentina, the World Trade Organization ("WTO") established a panel of experts to consider whether the DOC's antidumping order applicable to Argentina is consistent with the international obligations of the United States. As a result of the investigation, and unless overturned on appeal, Tenaris is required to pay antidumping duty deposits (at a rate of 78.30% for imports from Argentina and 44.93% for imports from Mexico) until such time the imports are reviewed by the DOC to determine whether final duties are necessary for the specific period under review. Tenaris has been paying such deposits since May 11, 2022, reflecting the amount of such deposits in its costs. The deposit rates may be reset periodically based on the results of the review process. It is possible that, through the periodic review process, the deposits may be either returned to Tenaris in whole or in part, or may be increased.

▪ Potential dispute with agent in the Middle East

Consistent with local practice in certain Middle East countries, Tenaris Global Services S.A. ("TGSU"), a subsidiary of the Company, sells materials to a local agent, and the agent then resells the materials to customers in the region. Tenaris is not a party to the contracts between the agent and each customer. In one such contract entered into in mid-2021, with pending obligations of approximately \$520 million and deliveries until 2025, the agent agreed to supply Tenaris-produced casing and tubing of different sizes to the customer. Subsequent events led to onerous increases in prices and delays to supply the materials and, after lengthy discussions, the customer recently agreed to partially recognize such increased costs. However, negotiations remain ongoing between the parties with respect to other items. Tenaris believes, based on the advice of counsel, that the customer should not be entitled to make any direct claim against TGSU in the event the dispute escalates.

(ii) Commitments and guarantees

Set forth is a description of the Tenaris's main outstanding commitments:

  • Certain subsidiaries of the Company entered into a contract with Praxair S.A. for the service of oxygen and nitrogen supply. As of December 31, 2023, the aggregate amount to take or pay the committed volumes for an original 14 year term totaled approximately \$32.7 million.
  • A subsidiary of the Company entered into a 25-year contract (effective as of December 1, 2016, through December 1, 2041) with Techgen for the supply of 197 MW (which represents 22% of Techgen's capacity). Monthly payments are determined on the basis of capacity charges, operation costs, back-up power charges, and transmission charges. As of the seventh contract year (as long as Techgen's existing or replacing bank facility has been repaid in full), the Company's subsidiary has the right to suspend or early terminate the contract if the rate payable under the agreement is higher than the rate charged by the Comisión Federal de Electricidad ("CFE") or its successors. The Company's subsidiary may instruct Techgen to sell to any affiliate, to CFE, or to any other third party all or any part of unused contracted energy under the agreement and the Company's subsidiary will benefit from the proceeds of such sale.
  • A U.S. subsidiary of the Company is a party to a contract with Nucor Steel Memphis Inc. under which it is committed to purchase on a monthly basis a specified minimum volume of steel bars, at prices subject to quarterly adjustments. The contract became effective upon delivery of the first purchase order, which occurred in April 2021, with an original duration of 3 years. In September 2023, the parties agreed to extend its term until December 31, 2024. As of December 31, 2023, the estimated aggregate contract amount calculated at current prices, was approximately \$73.7 million. The contract gives the subsidiary of the Company the right to temporarily reduce the quantities to be purchased thereunder to 75% of the agreed-upon minimum volume in cases of material adverse changes in prevailing economic or market conditions.

  • In connection with the closing of the acquisition of IPSCO, a U.S. subsidiary of the Company entered into a 6-year master distribution agreement (the "MDA") with PAO TMK ("TMK") whereby, since January 2, 2020, Tenaris became the exclusive distributor of TMK's OCTG and line pipe products in United States and Canada. At the end of the MDA's 6-year term, TMK would have the option to extend the duration of its term for an additional 12-month period. Under the MDA, the Company is required to purchase specified minimum volumes of TMK-manufactured OCTG and line pipe products, based on the aggregate market demand for the relevant product category in the United States in the relevant year. In February 2022, however, the Company and TMK agreed that there would be no minimum yearly purchase requirement for the OCTG product category for the year ended December 31, 2022, and there would be no minimum yearly purchase requirement for TMK line pipe products under the MDA neither for the contract year ended December 31, 2022, nor for any subsequent contract year until expiration of the MDA's term. In addition, no purchases of TMK products were made during 2023. The parties are currently discussing the termination of the MDA.

  • A Brazilian subsidiary of the Company entered into a contract with Usiminas and Gerdau from which it committed to purchase steel coils for a remaining amount of approximately \$109.6 million to use for manufacturing welded pipes for the Raia fields project in Brazil.
  • A subsidiary of the Company entered into a contract with the supplier JFE Steel Corporation for the purchase of tubular material, including 13 Chrome alloy products following the closure of NKKTubes. Such contract foresees a penalty for a maximum amount of \$30.9 million in case of early termination.

In addition, Tenaris (i) applied for stand-by letters of credit as well as corporate guarantees covering certain obligations of Techgen as described in note 14 (c) and (ii) issued performance guarantees mainly related to long-term commercial contracts with several customers and parent companies for approximately \$3.6 billion as of December 31, 2023.

(iii) Restrictions on the distribution of profits and payment of dividends

In accordance with Luxembourg Law, the Company is required to transfer a minimum of 5% of its net profit for each financial year to a legal reserve until such reserve equals 10% of the issued share capital.

As of December 31, 2023, this reserve is fully allocated and additional allocations to the reserve are not required under Luxembourg law. Dividends may not be paid out of the legal reserve.

The Company may pay dividends to the extent, among other conditions, that it has distributable retained earnings calculated in accordance with Luxembourg law and regulations.

28 Cancellation of title deed in Saudi Steel Pipe Company

In early 2021, the Company learned through the Saudi Ministry of Justice's online portal that the electronic title deeds to certain land plots of its Saudi Arabian subsidiary SSPC had become inactive due to cancellation by court order.

The affected land plots, with a total surface of 811,284 square meters, are located in Dammam, Saudi Arabia, and were purchased from a private entity on February 2010, pursuant to a written purchase agreement duly executed by SSPC in full compliance with the laws of the Kingdom of Saudi Arabia. The purchase of the land occurred before Tenaris's acquisition of a 47.79% interest in SSPC in 2019. The affected plots are not part of the production facility of SSPC, have been partially used as a warehouse, and have a carrying value on Tenaris's financial statements of \$56.2 million.

As of the date hereof, neither the cancellation nor the court order have been notified to SSPC or otherwise been made public by the authorities, and the legal basis for the court order is unknown. On May 4, 2021, SSPC filed a petition with an ad-hoc created special committee at the Saudi Ministry of Justice, seeking to have its title deeds reinstated. At this time, it is not possible to predict the outcome of this matter.

29 Foreign exchange control measures in Argentina

Between September 2019 and December 13, 2023, the Argentine government imposed significant restrictions on foreign exchange transactions. Although after a new administration took office in Argentina in December 2023 certain restrictions were eased and other changes to such regulations are expected, at the date of these Consolidated Financial Statements the application of existing foreign exchange regulations remains uncertain, and the scope and timing of upcoming changes remain unknown. The main currently applicable measures are described below:

  • Foreign currency proceeds derived from exports of goods must be sold into the Argentine foreign exchange market ("MULC") and converted into Argentine pesos within 60 days (if made to related parties) or 180 days (if made to unrelated parties) from shipment date, or, if collected earlier, within five days of collection. Foreign currency proceeds from exports of services must be sold into the MULC and converted into Argentine pesos within five business days of collection. As from December 13, 2023, up to 20% of export proceeds can be sold for Argentine pesos through securities transactions resulting in a higher implicit exchange rate, as described further below. This percentage has changed and is expected to change over time.
  • Access to the MULC to pay for imports of services rendered by related and non-related parties (including royalties) on or before December 12, 2023, is subject to Argentine Central Bank approval. Currently, these approvals are rarely, if ever, granted. Access to the MULC to pay for imports of services that were rendered or accrued as from December 13, 2023, does not require government approval, but payment is deferred 30 calendar days as from the date of supply or accrual of the service (if the service was rendered by a non-related party) or 180 calendar days (if rendered by a related party).
  • Access to the MULC to pay for imports of goods is subject to several restrictions. For example, advance payments or at sight cannot be made. In addition:
  • Access to the MULC to pay for imports of goods that obtained customs clearance on or before December 12, 2023 requires the prior Argentine Central Bank approval. The Argentine Central Bank is currently issuing newly created Bonds ("BOPREALs") with a maturity of 4 years (i.e., maturing in 2027) that can only be purchased in Argentine Pesos in primary offerings by debtors of any such import debts; such bonds can then be sold for a price payable in foreign currency that can be subsequently used to pay suppliers without subjecting the importer to any restriction to enter into any other foreign exchange transaction in the MULC. A secondary market for the BOPREALs is still in formation. In addition, from April 1, 2024 any such importer who purchased BOPREALs in primary offerings may enter into the securities transactions described below to obtain foreign currency (for an amount that does not exceed the difference in USD between the nominal value of the bonds and their market prices) and use such foreign currency to pay the above-mentioned import debts, without subjecting the importer to any restriction to enter into any other foreign exchange transaction in the MULC.
  • Access to the MULC to pay for imports that have obtained customs clearance as from December 13, 2023, does not require government approval but, it requires that the price is paid in four equal instalments payable on the 30th, 60th, 90th and 120th day counted from the customs clearance of the good imported.
  • Access to the MULC to make dividend payments requires prior Argentine Central Bank approval. When required, Argentine Central Bank approvals are rarely, if ever, granted.

The above-described measures substantially limit the ability of Argentine companies to obtain foreign currency and make certain payments and distributions out of Argentina through the MULC at the official exchange rate.

Access to foreign currency and transfers out of Argentina can be achieved, however, through securities transactions involving bonds or shares with multiple listings, resulting in a different implicit exchange rate, generally higher than the official exchange rate. Such transactions are subject to certain restrictions and limits, which change from time to time, and often result in a financial loss being generated at the time of making any such transaction. For example, in the past, the Argentine Securities Commission imposed several additional restrictions on such securities transactions, including a requirement to give prior notice to the Argentine government of any proposed transfer of securities outside of Argentina and a limitation on the amount of any such transfers. The new Argentine Securities Commission's authorities has loosened certain of such limitations, although it is not clear if it will further eliminate or loosen remaining restrictions.

During May 2023, two Argentine subsidiaries of the Company, approved the distribution of dividends in kind to their foreign shareholders, which were paid with U.S. dollar-denominated Argentine bonds that, in the Argentine market had a valuation of approximately \$356 million. Considering that, as a result of the foreign exchange restrictions in force, the value of such bonds in the international market as of the distribution date, was approximately \$174.1 million, the Company recorded a negative equity reserve (FVOCI). Subsequently, the valuation of such bonds in the international market increased. With the disposal of a portion of these instruments, the Company partially reclassified such reserve to financial results. The FVOCI as of December 31, 2023, amounted to approximately \$13.1 million.

The exchange rate of the Argentine peso against the U.S. dollar devaluated by more than 100% upon the change of government. Tenaris's financial position in Argentine pesos as of December 31, 2023, amounted to a net short exposure of approximately \$135 million. In the event of an additional devaluation, our Argentine subsidiaries, which hold U.S. dollar-denominated Argentine bonds for an aggregated value of \$208.6 million, may be adversely affected, and will also suffer a loss on deferred tax charge as a result of a deterioration on the tax value of their fixed assets. At this time, the Company is unable to estimate all impacts of a new devaluation of the Argentine peso against the U.S. dollar.

As of December 31, 2023, the total equity of Argentine subsidiaries represented approximately 9% of Tenaris's total equity and the sales made by Argentine subsidiaries during the year ended December 31, 2023, amounted approximately to 22% of Tenaris's total sales. Assets and liabilities denominated in Argentine peso as of December 31, 2023, are valued at the prevailing official exchange rate.

This context of volatility and uncertainty remains in place as of the issue date of these Consolidated Financial Statements. Management continues to monitor closely the evolution of the main variables affecting its business, identifying the potential impact thereof on its financial and economic situation and determining the appropriate course of action in each case. These Consolidated Financial Statements should be read taking into account these circumstances.

34 Business combinations

The application of the purchase method requires certain estimates and assumptions, mainly concerning the determination of the fair values of the acquired intangible assets, property, plant and equipment as well as the liabilities assumed at the date of the acquisition, including the timing and amounts of cash flow projections, the revenue growth rates, the customer attrition rates and the discount rate. The fair values determined at the acquisition date are based on discounted cash flows and other valuation techniques.

The preliminary purchase price allocations were carried out with the assistance of third-party experts. Following IFRS 3, the Company will continue reviewing the allocations and make any necessary adjustments during the twelve months following each of the acquisition dates.

Whenever applicable, Tenaris recognizes the non-controlling interest at the proportionate share of the acquiree's net identifiable assets.

Global Pipe Company acquisition

▪ Acquisition and price determination

On May 17, 2023, SSPC acquired 22.3% of the shares of GPC from Erndtebruecker Eisenwerk ("EEW"), a German company that owned a 35% interest in GPC, for a purchase price of \$6.3 million, paid in cash. SSPC already owned 35% interest in GPC, and, as a result of this transaction, SSPC currently holds a 57.3% interest in GPC.

The Company consolidates GPC's balances and results of operations as from May 17, 2023. The acquired business , which, contributed revenues of \$144.2 million with a minor contribution to Tenaris's results for the period starting May 17, 2023 and ending December 31, 2023, were assigned to Tubes segment. Had the transaction been consummated on January 1, 2023, then Tenaris's unaudited pro forma net sales and net income would not have changed materially.

▪ Fair value of net assets acquired

The allocation of the fair values determined for the assets and liabilities arising from the acquisition is as follows:

Fair value of acquired assets and liabilities as of acquisition date (May, 17, 2023): \$ million
Property, Plant and Equipment 173
Working capital 34
Cash and Cash Equivalents 2
Borrowings (123)
Other assets and liabilities, net (6)
Net assets acquired 80

Tenaris accounted for this transaction as a step-acquisition whereby Tenaris's ownership interest in GPC held before the acquisition, which amounted to \$23.5 million, was remeasured to fair value at that date. As a result, Tenaris recorded a gain of approximately \$4.5 million resulting from the difference between the carrying value of its initial investments in GPC and the fair value, which was included in Equity in earnings of non-consolidated companies in the Consolidated Income Statement. The non-controlling interests in GPC amounted to \$34.1 million.

The fair value of the net assets and liabilities acquired shown above amounted to approximately \$80 million. As a result of the acquisition, Tenaris recognized an additional gain for approximately \$11.5 million also included in Equity in earnings of non-consolidated companies in the Consolidated Income Statement.

Acquisition-related costs for the year ended 2022 were not material and for the year ended December 31, 2023, amounted to \$0.3 million and were included in general and administrative expenses.

SSPC and the other owners of GPC have issued corporate guarantees to secure the repayment of loan agreements entered into by GPC with the Saudi Investment Development Fund, the Saudi British Bank, the National Commercial Bank and Banque Saudi Fransi to finance GPC's capital expenditures and working capital.

As a result of this acquisition, SSPC assumed a portion of EEW's corporate guarantees. As of December 31, 2023, SSPC's aggregate exposure to GPC's financial debt amounted to \$72 million.

Acquisition of Anticorrosion Coating Assets in Italy

▪ Acquisition and price determination

On July 1, 2023, an Italian subsidiary of the Company completed its previously announced acquisition of all of the assets and related rights, duties, liabilities and contracts of Isoplus Mediterranean S.r.l.'s ("Isoplus") anticorrosion coating division for EUR9.0 million (approximately \$9.8 million) paid in cash.

Isoplus was established in 2009 in Villamarzana in Italy. It operates in an area of about 65,000 square meters (covered and uncovered) with pipe pre-insulation (district heating) and anticorrosive coating (oil & gas) production lines.

The Company consolidated Isoplus anticorrosion coating division balances and results of operations as from July 1, 2023. The acquired business revenues, assigned to Tubes segment, were not material, with a minor contribution to the Company's results for the period starting July 1, 2023 and ending December 31, 2023. Had the transaction been consummated on January 1, 2023, then Tenaris's unaudited pro forma net sales and net income would not have changed materially.

▪ Fair value of net assets acquired

The allocation of the fair values determined for the assets and liabilities arising from the acquisition is as follows:

Fair value of acquired assets and liabilities as of acquisition date (July, 1, 2023): \$ million
Property, Plant and Equipment 11
Working capital 2
Net assets acquired 13

The fair value of the net assets and liabilities acquired shown above amounted to approximately \$13 million. As a result of the acquisition, Tenaris recognized an additional gain for approximately \$3.2 million also included in Other Income and Expenses in the Consolidated Income Statement.

Acquisition-related costs for year ended December 31, 2023, were not material and were included in general and administrative expenses.

Acquisition of Republic Tube pipe processing facility

▪ Acquisition and price determination

On September 6, 2023, a U.S. subsidiary of the Company acquired all of the assets and related rights, duties, liabilities and contracts of Republic Tube LLC's OCTG pipe processing facility in Houston, Texas. The final acquisition price amounted to \$90.5 million in cash.

The plant, located on the northeast side of Houston, adds heat treatment and finishing lines, further complementing Tenaris's existing operations, and increasing its capacity to serve the domestic market.

The Company consolidated the balances and results of operations of the acquired business as from September 6, 2023. The acquired business revenues, assigned to Tubes segment, were not material, with a minor contribution to the Company's results for the period starting September 6, 2023, and ending December 31, 2023. Had the transaction been consummated on January 1, 2023, then Tenaris's unaudited pro forma net sales and net income would not have changed materially.

35 Nationalization of Venezuelan subsidiaries

Following the nationalization by the Venezuelan government of the Company's interests in its majority-owned subsidiaries TAVSA - Tubos de Acero de Venezuela S.A. ("Tavsa") and Matesi Materiales Siderúrgicos S.A ("Matesi") and in Complejo Siderúrgico de Guayana, C.A ("Comsigua"), the Company and its wholly-owned subsidiary Talta - Trading e Marketing Sociedad Unipessoal Lda ("Talta") initiated arbitration proceedings against Venezuela before the ICSID in Washington D.C. in connection with these nationalizations and obtained favorable awards, which are final and not subject to further appeals.

Matesi

On January 29, 2016, the tribunal released its award on the arbitration proceeding concerning the nationalization of Matesi. The award upheld Tenaris's and Talta's claim and granted compensation in the amount of \$87.3 million for the breaches and ordered Venezuela to pay an additional amount of \$85.5 million in pre-award interest, aggregating to a total award of \$173.0 million (including \$0.2 million of legal fees), payable in full and net of any applicable Venezuelan tax, duty or charge.

On June 8, 2018, Tenaris and Talta filed an action in federal court in the District of Columbia to recognize and enforce the award in the United States. On July 17, 2020, the court entered judgment recognizing the Matesi award. The judgment orders Venezuela to pay to Tenaris and Talta an amount of \$256.4 million, including principal and post-award interest through the judgment date, and provides for post-judgment interest to accrue on this sum at the U.S. federal statutory rate.

Tavsa and Comsigua

On December 12, 2016, the tribunal issued its award upholding Tenaris's and Talta's claim and granted compensation in the amount of \$137.0 million and ordered Venezuela to pay an additional amount of \$76.0 million in pre-award interest and to reimburse Tenaris and Talta \$3.3 million in legal fees and ICSID administrative costs. In addition, Venezuela was ordered to pay interest from April 30, 2008, until the day of effective payment at a rate equivalent to LIBOR + 4% per annum.

On June 8, 2018, Tenaris and Talta filed an action in federal court in the District of Columbia to recognize and enforce the award in the United States. On March 29, 2021, the court granted Tenaris's and Talta's request to recognize the Tavsa award and on August 24, 2021, the court entered judgment in favor of Tenaris and Talta and against Venezuela in the amount of \$276.9 million, with post-judgment interest accruing from the date of judgment at the federal statutory post-judgment interest rate. On November 5, 2021, the court, in response to a motion by Tenaris and Talta, amended the judgment amount to \$280.7 million, with post-judgment interest continuing to accrue from August 24, 2021, at the federal statutory post-judgment interest rate.

Transfer of the Awards and Judgements

On January 25, 2023, Tenaris and Talta entered into an awards purchase agreement with an unaffiliated purchaser pursuant to which Tenaris and Talta agreed to sell all of their rights, title and interests in the above-referenced claims, awards and judgements, including all post-award or post-judgement interest accruing on the awards and judgements, for a purchase price of \$81 million, plus a non-refundable signing payment of \$1 million as reimbursement of expenses.

After the U.S. Office of Foreign Assets Control approved the transfer of the awards and judgements to the purchaser, the transfer was consummated on September 7, 2023. As a result, the Company collected \$82 million in the year ended December 31, 2023. The Company does not maintain any residual interest in these awards and judgements. The net result derived from this operation amounted to \$33.3 million.

36 Termination of NKKTubes joint venture

NKKTubes, a company owned 51% by Tenaris and 49% by JFE Holdings Inc. ("JFE"), used to operate a seamless pipe manufacturing facility in Japan, located in the Keihin steel complex owned by JFE. On March 27, 2020, JFE informed Tenaris of its decision to permanently cease as from JFE's fiscal year ending March 2024 the operations of its steel manufacturing facilities located at the Keihin complex. On November 2, 2021, Tenaris and JFE agreed to terminate amicably their joint venture and liquidate NKKTubes. On November 2, 2022, Tenaris and JFE entered into a definitive wrap-up agreement. NKKTubes was liquidated on April 28, 2023.

37 Share Buyback Program

On November 1, 2023, the Company's board of directors approved a share buyback program of up to \$1.2 billion (which, at the closing price of November 1, 2023 on the Milan Stock Exchange, would represent approximately 75.4 million shares, or 6.4% of the outstanding shares), to be executed within a year, with the intention to cancel the ordinary shares acquired through the program.

The buyback program is being carried out under the authority granted by the annual general meeting of shareholders held on June 2, 2020, which may be renewed or extended, up to a maximum of 10% of the Company's shares. The buybacks may be ceased, paused and continued at any time, subject to compliance with applicable laws and regulations.

The program is divided into tranches. For purposes of carrying out the first tranche of the buyback program, Tenaris entered into a non-discretionary buyback agreement with a primary financial institution that makes trading decisions concerning the timing of the purchases of Tenaris's ordinary shares independently of and uninfluenced by Tenaris and must act in compliance with applicable rules and regulations, including the Market Abuse Regulation 596/2014 and the Commission Delegated Regulation (EU) 2016/1052. Under the buyback agreement, purchases of shares may continue during any blackout periods.

During 2023, the Company purchased 12,648,091 shares, for a value of \$213.7 million. As of December 31, 2023, the Company held a liability in connection to the shares to be settled under the first tranche of the buyback program that amounted to \$86.2 million. On January 12, 2024, the first tranche of the share buyback program was completed.

Further information on the buyback transactions is available on Tenaris's corporate website under the Share Buyback Program Section.

38 Climate change

Tenaris carefully assesses the potential impact of climate change and energy transition on its business and on the risks to its markets and its tangible and intangible assets, and adapts its business strategy accordingly.

In February 2021 Tenaris set a medium-term target to reduce its carbon emissions intensity rate by 30% by 2030, compared to a 2018 baseline, considering Scopes 1 and 2 emissions plus Scope 3 emissions related to raw materials and steel purchased from third parties. Tenaris encourages the use of sustainable practices among its suppliers and, in March 2023, it adopted a Sustainable Sourcing Policy to enhance its efforts in this area. The new Sustainability Sourcing Policy will help Tenaris to understand better the real emission levels of its suppliers and identify further opportunities for improvement. The Company aims to achieve this target by using a higher proportion of recycled steel scrap in the metallic mix and by making investments to increase energy efficiency and the use of renewable energy in its energy requirements. In particular, a large proportion of these investments are being directed to installing renewable energy capacity for use in the Company's operations. In October 2023, following an investment of approximately \$200 million, Tenaris put into operation a wind farm in Argentina, which supplies 103.2 MW of power, or close to 50% of its total electric power requirements, through the interconnected grid, to its industrial facilities in Campana. The wind farm will reduce Tenaris's CO2 emissions at the facility by 152,000 tons per year compared to 2018. In November 2023 the Company's Board of Directors approved an investment plan to build a second wind farm in Argentina at a cost of approximately \$214 million, which would supply a further 30% of the current energy requirements of its facilities in Campana, and reduce Tenaris's CO2 emissions by a further 102,500 tons per year. The medium-term target forms part of a broader objective of decarbonizing our operations and reaching carbon neutrality. At the same time, the Company is increasing its sales for low-carbon energy applications, such as hydrogen, geothermal and carbon capture and storage. These sales currently account for a relatively small proportion of overall sales but are expected to grow in the coming years.

In its assessment, Tenaris also considers that the countries in which it operates and its customers are also establishing their own decarbonization strategies and objectives, and that some customers are requesting specific information from their suppliers, including Tenaris, concerning the carbon emissions and Environmental, Social and Governance ("ESG") practices in their supply chain, and that they may adjust their supply practices in light of that information.

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