Most Supervisory Board meetings were also attended by all or by most members of the Managing Board. In addition, several managers were invited to discuss specific items included on the Supervisory Board’s agenda.

Large parts of the meetings of the Supervisory Board that were held on 19 March 2021, and 12 October 2021 were dedicated to Euronext’s strategy. During the meetings held in 2021, the Supervisory Board approved among others the quarterly and semi-annual financial statements, the semi-annual report, the universal registration document for 2020, the budget for 2022, and the agendas of the General Meetings, including the nomination for appointments to the Supervisory Board and the Managing Board, the nomination of the external auditor, and a proposal regarding the dividend. All meetings of the Supervisory Board were prepared by the Chairman of the Managing Board in close co-operation with the Chairman of the Supervisory Board. BOARD EVALUATION The annual evaluation of the Supervisory Board and its Committees relating to 2021 took place in February 2022.
