SUSTAINABILITY STATEMENT Social and societal information

● the group’s participation in an assessment of the corporate safety culture thanks to the WANO network (World Association of Nuclear Operators), of which Orano is a member. This assessment was carried out on the basis of best practices implemented in the nuclear industry and resulted in the de fi nition of a long-term roadmap; ● cross-functional action in terms of visible and impactful fi eld managerial presence ; ● the review and standardization of the group’s business continuity plans in order to better integrate the variety of initiating events. In 2026, the group will roll out the safety culture roadmap, particularly in terms of fi eld presence.

2025 IN ACTION Visible and impactful fi eld managerial presence Orano has chosen fi eld presence as a priority theme for 2025. A diagnostic phase carried out with managers in the fi eld identi fi ed the main obstacles and conditions for success in having a visible and impactful managerial presence on a daily basis. It led to the distribution of a guide, drafted cross functionally with the operational entities, which will be rolled out in 2026. It summarizes: ● the obstacles generally encountered; ● the success factors to exceed them; ● the list of practices promoting an active presence in the fi eld; ● inspiring examples of best practices, both internal and external.

Orano, a member of GIFEN, is committed to the desire to advance the French nuclear industry. As part of its 2024-2026 Quality policy, Orano therefore undertakes to: ● learn from our operating feedback to strengthen our quality culture and improve performance; ● commit to satisfying customers in terms of quality-cost-delivery performance and without compromising nuclear safety; and ● make Orano’s interests and those of its suppliers converge more closely to better control our supplies and subcontracting .
