Orano - Annual Activity Report 2025 397 FINANCIAL STATEMENTS 6 Company financial statements – financial year ended December 31, 2025 3.1 Impact of the change in accounting methods on the main items of the 2025 financial year 3.1.1 Impact of the new definition of exceptional items on the 2025 financial year As of January 1, 2025, in accordance with Article 513-5 of French GAAP, exceptional items include: ● income and expenses directly related to a major and unusual event that would not have been recognized in the absence of this event; ● accounting entries of exclusively tax origin, such as accelerated depreciation; ● changes in accounting methods recognized in profit or loss when their treatment in equity is excluded due to tax provisions; ● corrections of errors, except for those relating to entries initially charged directly to equity. This change entails the classification in current operating income of transactions which, prior to the application of the new regulation, were recognized as exceptional items by nature. The main impacts are detailed below: Disposals and scrapping of intangible and tangible fixed assets At December 31, 2025, the disposals and scrappings of intangible and tangible assets when they are not directly related to a major and unusual event are recognized in operating income (expense). The proceeds of these disposals are shown in “Proceeds from disposals of tangible and intangible assets” and the net carrying amounts of non-current assets under “Carrying amount of tangible and intangible assets sold”. No such transactions took place in 2025. At December 31, 2024, the disposal and scrapping of non-current assets are recognized in exceptional items. The proceeds from the sale are shown under “Exceptional income” for 2,700 thousand euros and the net carrying amounts of non-current assets under “Exceptional expenses” for 8 thousand euros. Disposals and scrapping of financial investments As at December 31, 2025, disposals of financial investments are recognized in net financial income (expense) when they are not directly related to a major and unusual event. The proceeds of these disposals are shown in “Proceeds from disposals of financial investments” and the net carrying amounts of the non-current assets under “Carrying amount of financial investments sold”. No such transactions took place in 2025. At December 31, 2024, the disposal and scrapping of non-current assets are recognized in exceptional items. The proceeds from the sale are shown under “Exceptional income” for 105 thousand euros and the net carrying amounts of non-current assets under “Exceptional expenses” for 105 thousand euros. Fines and penalties At December 31, 2025, fines and penalties that do not relate to a major and unusual event were recognized in operating income (expense) under “Other expenses”. No such transactions took place in 2025. At December 31, 2024, they appeared under “Exceptional expenses” for 10 thousand euros. 3.1.2 Impacts of the elimination of the expense transfer technique in financial year 2025 The elimination of the expense transfer technique results in the reclassification of transactions that, prior to the application of the new regulation, were recorded under “Reversals of depreciation, amortization, impairment, and provisions and expense transfers” to other expense or income items. The main impacts are detailed below. At December 31, 2024, “Expenses transfers” included in operating income amounted to 75 thousand euros corresponding to insurance indemnities. At December 31, 2025, insurance indemnities were recognized in operating income under “Other income” for 44 thousand euros. 3.2 Presentation of the comparative column (financial year 2024) Reclassifications and groupings have been made in the “2024” comparative column, between lines of the balance sheet or income statement, to comply with the new format of the financial statements. In the comparative column: ● intangible assets in progress are grouped with advances and prepayments; ● tangible fixed assets in progress are grouped with advances and prepayments; ● the line “Prepaid expenses” is moved up between the items “Receivables” and “Marketable securities”; ● the line “Forward financial instruments” is moved up between the item “Miscellaneous loans and financial liabilities” and that of “Advances and prepayments received on orders in progress”; ● transfers of operating expenses are presented under “Reversals of depreciation, amortization and provisions”; ● exceptional income and expenses are grouped under the two lines “Exceptional income” and “Exceptional expenses”.
