Press release – regulated information

OPTIONAL DIVIDEND : 60.35% OF THE SHAREHOLDERS CHOOSE TO TAKE THEIR DIVIDEND IN SHARES CAPITAL INCREASE OF 7,939,166.235 EUR (SHARE PREMIUM INCLUDED)

La Hulpe (Belgium), 27 June 2023 at 6:00 pm (Belgian time)

As announced during the General Meeting held on 28 April 2023, ATENOR shareholders have been given the opportunity, during the period between 7 June 2023 and 20 June 2023 (included), to opt for the issuance of new shares in exchange for their dividend rights relating to the net dividend of 1.869 EUR for the financial year 2022. 60.35% of the shareholders, including the large majority of the reference shareholders, have decided to exchange their net dividend rights for new shares, instead of receiving the payment of their dividends in cash.

This success increases once more our shareholders' loyalty and enables them to subscribe for new shares at an attractive price. It also contributes to the financial solidity of the group.

This optional dividend has made it possible, this date, to increase ATENOR's capital by 7,939,166.235 EUR (share premium included) by the issuance of 386,165 new shares.

These new shares will be admitted to trading on the regulated market of Euronext Brussels as from 28 June 2023. As from this date, the dividend in cash shall also be paid to the shareholders according to the procedure laid down in the "Information document" published on our website since 6 June 2023.

Notification in accordance with article 15 of the Law of 2 May 2007 relating to the publication of large shareholdings in issuers from which the shares are admitted to trading on a regulated market and relating to miscellaneous provisions (Law on transparency).

After the capital has been increased this day, ATENOR's capital will amount to 75,990,388.72 EUR, represented by 7,425,010 shares, each accompanied with a right to vote at the General Meeting.
