2.1.6

RENEWAL OF THE APPOINTMENT OF ACA NEXIA AS PRINCIPAL STATUTORY AUDITOR (RESOLUTION 16)

The appointment of Yves de Talhouët would have no impact on the proportion of Independent Directors (about 67%), the proportion of female Directors (42%), or the average age of Board members (63.1). In Resolution 11, the Board of Directors asks that you renew the directorship of André Einaudi for a term of office of four years, on the recommendation of the Nomination, Governance, Ethics and Corporate Responsibility Committee. In Resolution 12, the Board of Directors asks that you renew the directorship of Michael Gollner for a term of office of one year, on the recommendation of the Nomination, Governance, Ethics and Corporate Responsibility Committee. In Resolution 13, the Board of Directors asks that you renew the directorship of Noëlle Lenoir for a term of office of four years, on the recommendation of the Nomination, Governance, Ethics and Corporate Responsibility Committee. In Resolution 14, the Board of Directors asks that you renew the directorship of Jean-Luc Placet for a term of office of two years, on the recommendation of the Nomination, Governance, Ethics and Corporate Responsibility Committee. In Resolution 15, the Board of Directors asks that you appoint Yves de Talhouët as a Director for an initial term of office of three years, on the recommendation of the Nomination, Governance, Ethics and Corporate Responsibility Committee.

In accordance with the recommendations of the Audit Committee, which oversees the selection process for Statutory Auditors, the Board of Directors unanimously proposes that the appointment of ACA Nexia as one of the Company’s two Principal Statutory Auditors be renewed for a period of six years that will end at the close of the General Meeting convened in 2028 to approve the financial statements for the year ending 31 December 2027. The reasons put forward by the Audit Committee to justify its recommendation to the Board of Directors are the quality of services provided by the firm, the satisfactory collaboration in place between the Statutory Auditor teams, and the schedule of upcoming changes in application of the procedure for the rotation of Statutory Auditors. In addition, the Board of Directors, having noted the elimination of the requirement that companies that have a legal entity as their Principal Statutory Auditor appoint one or more Alternate Statutory Auditors as well as the related amendments to the Articles of Association approved by shareholders at the General Meeting of 13 June 2017, is not proposing the appointment of a new firm as Alternate Statutory Auditor. Should any of its representatives be unable to carry out their duties. ACA Nexia will appoint another representative. It should be noted that, under the same conditions, the appointment of Jean-Louis Simon, Alternate Statutory Auditor at Mazars, was not renewed at the General Meeting of 12 June 2018. The shareholders at General Meeting will be asked to acknowledge this as a matter of good form.
