The compensation and nominating committee, in coordination with the Chairman of the Board of directors, the Chief Executive Officer and the group’s Human Resources Department, made sure that the Company had put in place the necessary mechanisms to allow for the immediate replacement, on an interim basis, of the Chief Executive Officer, should the latter suddenly prove incapacitated or unavailable to run the Company’s operations. With a view to replacing the Chief Executive Officer at the end of his term of office or in the event of resignation, the compensation and nominating committee has also drawn up a standard profile for the position of Chief Executive Officer of Orano, to allow an open search procedure to be undertaken for internal and external candidates. The succession plan of the Chief Executive Officer is regularly monitored by the Chairman of the Board of directors, the Chairman of the compensation and nominating committee and the Human Resources Department. Since the appointment of Nicolas MAES as Chief Executive Officer of Orano, on November 15, 2023, a new succession plan for the Chief Executive Officer has been put in place and was reviewed by the compensation and nominating committee on February 11, 2025 and reported to the Board of directors on February 18, 2025. At its meeting on February 12, 2026, the compensation and nominating committee also reviewed more broadly the succession plan for members of the executive committee and key positions within the group.
