The Orano group internal control framework details the key controls to be implemented by all entities to address the risks identi fi ed in this accounting basis, particularly in connection with the preparation of fi nancial information (for more information on the operation of the internal control system, see Section 3.1). Accounting and fi nancial internal control covers the processes that feed into the accounting and fi nancial data and mainly the processes for closing the fi nancial statements and producing and publishing accounting and fi nancial information. The internal control system aims to ensure: ● compliance with accounting regulations, as well as the proper application of standards and methods for preparing fi nancial information; ● the preservation of the group’s assets; ● prevention and detection of accounting and fi nancial irregularities or fraud; ● the reliability of accounting and fi nancial information by controlling the production of accounting and fi nancial information. The scope of application of the internal control procedures relating to the preparation of accounting and fi nancial information includes the parent company (Orano SA) and all fully consolidated entities or whose assets are under joint control. At the level of the parent company, the preparation and processing of accounting and fi nancial information is the responsibility of the Finance Department, which includes the Management Control and Accounting Department (DCGC), the Financing Operations Department. and Treasury and the Tax Department. The main role of the DCGC is to produce the separate and consolidated fi nancial statements of the entities forming the Orano group in strict compliance with French and international accounting standards. It centralizes fi nancial information, coordinates the

monthly reporting processes and ensures the consistency of the information transmitted by the various entities. It also ensures that the group’s accounting principles are circulated to all those involved in the process, which are de fi ned in a regularly updated document. The group Internal Audit Department is also required, as part of its work, to validate on an ad hoc basis the proper implementation by the subsidiaries of the group’s internal control accounting basis relating to fi nancial processes and informs the Finance Department of any points of attention identi fi ed. The Financial Communication Department manages the review committees in conjunction with the DCGC in order to review the fi nancial information before its publication. In particular, it ensures the precision, accuracy and consistency of the information with regard to both regulatory requirements and the expectations of the various players (investors, administrative authorities, rating agencies, etc. ). The Audit and Ethics Committee supervises and monitors issues relating to the preparation and control of accounting and fi nancial information. As such, it monitors the process of preparing fi nancial information and, where applicable, makes recommendations to ensure the integrity of this process. It also ensures the effectiveness of the internal control, risk management and internal audit systems. The Statutory Auditors of Orano SA conduct a limited review of the consolidated fi nancial statements at June 30 and certify the separate and consolidated fi nancial statements at December 31 of each year. As part of their certi fi cation of the consolidated fi nancial statements, the Statutory Auditors audit the information provided by the subsidiaries included in the scope selected for their work. They attend all meetings of the Audit and Ethics Committee, inform it of any signi fi cant points raised during their control work and present their audit plan for the coming fi nancial year.
