The amount of provisions at December 31, 2024 falling within and outside the scope of the Law is: 9,059 million euros in present value (Note 13 to the consolidated fi nancial statements). The waste inventory at December 31, 2024 will be communicated at the end of the fi rst half of 2025. To ensure the proper management of its end-of-lifecycle obligations, Orano has set up two committees: ● the End-of-Lifecycle Obligations Monitoring Committee at the level of the Board of Directors (specialized committee); and ● the Dismantling Operations Monitoring Committee (COSOD) reporting to the Executive Committee.

Provisions for mining site remediation These provisions correspond to foreseeable expenses stemming from the cost of rehabilitating mining sites borne by the group. The provision is constituted as and when the site is operated, in accordance with the principle of progressive deterioration. The provision for mining site reclamation is equal to the proportion of tonnages processed since the commissioning of the site compared to the total tonnage of the site (quantities already processed and yet to be processed). At December 31, 2024, these provisions amounted to 283 million euros.

4.2.5 An industrial actor committed to the preservation of resources, the circular economy and waste optimization [E5]

A production process respecting the principles of the circular economy aims to extend the life cycle of products, in order to reduce the use of raw materials and the production of waste. The objective is to maximize and preserve the value of resources by creating a system that promotes: sustainability, reusability, repairability, disassembly, remanufacturing, reconditioning, recycling, recirculation through the biological cycle or optimization of the use of the product or materials through other circular economic models. Orano has made the preservation of resources at the core of its purpose and intends to contribute to the circular economy through its activities and actions.

4.2.5.1 IROs related to the use of resources and the circular economy For its materiality analysis and the identi fi cation of Impacts, Risks and Opportunities (IRO), Orano relied on its existing mapping (risks, vigilance), the knowledge of its experts and existing studies (impact studies, speci fi c studies, etc.) as well as interviews with 150 stakeholders, as described in Section 4.1.5.2 Double materiality analysis methodology .
