FINANCIAL STATEMENTS Statutory Auditors’ report on the company fi nancial statements for the fi nancial year ended December 31, 2025

This impairment is calculated on the basis of the share of the net assets held at the end of the year. Receivables from equity investments are carried at their nominal amount. These investments are impaired, where applicable, to take the subsidiary’s fi nancial position into account. Estimating the value in use of equity interests requires management to exercise signi fi cant judgment in the choice of measurement methods and items to consider, which may be historical (particularly equity values) or projected (cash flow assumptions). Given the signi fi cant amount of equity interests, the judgment used to estimate values in use and the sensitivity of these values to changes in the data and assumptions on which they are based, we deemed the measurement of equity interests and related receivables to be a key audit matter. How our audit addressed this risk Our audit procedures mainly consisted in: ● examining, on the basis of the information provided by management, the measurement methods used by the Company; ● comparing the data used to test the equity interests for impairment with the subsidiaries’ accounting data, where applicable; ● gaining an understanding of the methodology and assumptions used to determine the value in use of the equity interests when said value takes into account the subsidiaries’ projected pro fi tability; ● verifying the arithmetical accuracy of the value in use calculations used by the Company; ● assessing, with the help of our experts, the reasonableness of the assumptions used regarding the discount rate; ● assessing the sensitivity of the estimates of value in use used in the assumptions (particularly cash flow, discount rates and the long-term growth rate); ● assessing the recoverability of the related receivables in light of the analyses performed on the equity interests; and ● verifying the appropriateness of the disclosures provided in Notes 2.2, 5.3 and 5.4 to the fi nancial statements. Speci fi c veri fi cations In accordance with professional standards applicable in France, we have also performed the speci fi c veri fi cations required by French legal and regulatory provisions. Information given in the management report and in the other documents provided to the shareholders with respect to the Company’s fi nancial position and the fi nancial statements We have no matters to report as to the fair presentation and the consistency with the fi nancial statements of the information given in the Board of Directors’ management report and in the other documents provided to the shareholders with respect to the Company’s fi nancial position and the fi nancial statements. We attest to the fair presentation and the consistency with the fi nancial statements of the information about the payment terms referred to in Article D.441-6 of the French Commercial Code.

Report on corporate governance We attest that the section of the Board of Directors’ report relating to corporate governance sets out the information required by Articles L.225-37-4 and L.22-10-10 of the French Commercial Code. Other information In accordance with French law, we have veri fi ed that the required information concerning the purchase of investments and controlling interests has been properly disclosed in the management report. Other veri fi cations and information pursuant to legal and regulatory requirements Appointment of the Statutory Auditors We were appointed Statutory Auditors of Orano SA by the Annual General Meeting of May 24, 2018. At December 31, 2025, PricewaterhouseCoopers Audit and KPMG SA were in the eighth consecutive year of their engagement. Responsibilities of management and those charged with governance for the fi nancial statements Management is responsible for preparing fi nancial statements giving a true and fair view in accordance with French accounting principles, and for implementing the internal control procedures it deems necessary for the preparation of fi nancial statements that are free of material misstatement, whether due to fraud or error. In preparing the fi nancial statements, management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern, and using the going concern basis of accounting, unless it expects to liquidate the Company or to cease operations. The Audit and Ethics Committee is responsible for monitoring the fi nancial reporting process and the effectiveness of internal control and risk management systems, as well as, where applicable, any internal audit systems, relating to accounting and fi nancial reporting procedures. The fi nancial statements were approved by the Board of Directors.
