OPTIONAL DIVIDEND: 79.69% OF SHAREHOLDERS CHOOSE TO TAKE THEIR DIVIDEND IN SHARES CAPITAL INCREASE OF 6.52 MILLION EUROS

La Hulpe, 19 May 2015

As announced at the General Assembly on 24 April 2015, ATENOR GROUP's shareholders have been given the opportunity of opting for new shares in exchange for their dividend rights relating to the gross dividend of € 2 for the financial year 2014. 79.69% of shareholders, including all the reference shareholders, have decided to exchange their 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 and to our shareholders' confidence in the group's strategy.

This optional dividend will make it possible to increase ATENOR GROUP's capital by 6.52 million euros on 21 May 2015 by the creation of 173,812 new shares.

These new shares will be listed and admitted to Euronext Brussels from 26 May 2015.

As from this date, the dividend in cash shall also be paid according to the procedure laid down in the "Information notice" published on our website on 24 April 2015.

Notification in accordance with article 15 of the Law of 2 May 2007 relating to the publication of large shareholdings (Law on transparency).

After the capital has been increased on 21 May 2015, it will amount to 57.63 million euros represented by 5.631.076 shares, each accompanied with a right to vote at the General Meeting. This number of shares shall serve as a denominator in the calculation of the statutory or legal thresholds. As a reminder, article 13 of ATENOR GROUP's articles of association lays down an additional threshold of 3% in addition to the legal thresholds. Where applicable, shareholders are invited to make the necessary notifications.
