In 2021, the group set up a Stakeholders’ Panel, chaired by the Chairman of the Board of directors. The aim of this Panel, which has an advisory role, is to provide the Executive Management and the Company’s management with the perspective of external observers on the group’s social, societal, and environmental responsibility. The Panel is composed of stakeholders from outside the group and volunteers who represent Orano’s main stakeholders. Its roles are to: question and react constructively to the issues and challenges presented by management, or raised by members, relating to the way in which corporate social responsibility is included in the group’s strategy; convey stakeholders’ expectations of the group, including those who are farthest removed from our direct business activities; suggest ways forward and changes in direction; and, where appropriate, offer constructive advice on strategies and actions taken or to be taken. In 2025, the Stakeholders’ Panel met twice, including once at the Malvési site (France) to discuss plans to renew the facilities and the site’s attractiveness in terms of recruitment. Committee members also discussed with local stakeholders the challenges and their expectations with regard to Orano. The second session of 2025 was devoted to the progress of the group’s projects and its regional strategy.
