Diversity Until 1 January 2020 Dutch law required large Dutch companies to pursue a policy of having at least 30% of the seats on both the Managing Board and the Supervisory Board held by men and at least 30% of those seats held by women. Following a report of the Dutch “Sociaal Economische Raad”, a legislative proposal for Dutch large companies was adopted by the Dutch parliament and was submitted to the Senate in February 2021. In line with the expected legislation Euronext strives for appropriate and ambitious diversity targets at the top and sub top. Euronext aims at representing at least 30% of women at its Managing Board. Euronext qualifies as a large Dutch Company and complies with these gender diversity targets with respect to the Managing Board, as three of its nine members were female as at 31 December 2021. The Senior Leadership team in 2021 was composed of 34% of women. The balance of country representation was the following: 49% France, 9% Norway, 8% the Netherlands 8% Ireland, 6% Denmark, 6% Portugal, 6% United Kingdom, 4% Belgium, and 4% United States, 2% Spain. The average age of this group is 44 years. Euronext will continue to promote diversity within its Managing Boards by taking into account all relevant selection criteria including, but not limited to, gender balance, with regard to future appointments.
