 of the reporting dates, and the reported amounts of revenues and expenses for the reported periods. Actual results may differ from these estimates. The main areas involving significant estimates or judgments are impairment of goodwill and long-lived assets; impairment of investments in associates; income taxes (including recoverability of deferred tax assets); obsolescence of inventory; contingencies; allowance for trade receivables; post-employment and other long-term benefits; business combinations; useful lives of property, plant and equipment and other long-lived assets and fair value estimation of certain financial instruments. During the period there were no material
changes in the significant accounting estimates and judgements.

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. These events did not impact materially management judgments and estimates used in the preparation of these Consolidated Condensed Interim Financial Statements. For further information, see note 36 to our audited Consolidated Financial Statements for the year ended December 31, 2024.

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

There were no significant changes in valuation techniques during the period and there have been no changes in any risk management policies since the year ended December 31, 2024.

If necessary, comparative amounts have been reclassified to conform to changes in presentation in the current period.

None of the accounting pronouncements applicable after December 31, 2024, and as of the date of these Consolidated Condensed Interim Financial Statements had a material effect on the Company’s financial condition or result of its operations.
