(Article 14, paragraph 1 of the law of 2 May 2007 on the disclosure of major holdings)

Louvain-la-Neuve, Belgium, May 19, 2020, 17.30

Summary of the notification

IBA (Ion Beam Application), the world’s leading provider of proton therapy solutions for the treatment of cancer, received a transparency notification dated May 18, 2020, from which it follows that, following a passive crossing of a threshold on April 30, 2020, Belgian Anchorage SCRL, including the voting rights of its subsidiary Belgian Leverage SA, now holds 32.55% of the company's voting rights. It thus crossed upwards the 30% participation threshold.

Content of the notification

• Reason for the notification: Passive crossing of a threshold
• Notification by : A parent undertaking or a controlling person
• Persons subject to the notification requirement:
  
  Belgian Anchorage SCRL, Clos des Salanganes 5,1150 Brussels
  
  Belgian Leverage SA, Clos des Salanganes 5,1150 Brussels
• Date on which the threshold is crossed: 30/04/2020

• Statutory thresholds : 1%, 2%, 3%, 4%, 5%, 7.5%, 10%, 15%, etc. in 5% increments
• Denominator: 38 085 047

• Full chain of controlled undertakings through which the holding is effectively held

Belgian Leverage SA is the subsidiary of Belgian Anchorage SCRL, 99.99% owned by the latter (see annual accounts of Belgian Anchorage SCRL BNB 31.12.2018).

Belgian Anchorage SCRL has no other subsidiary within the meaning of article 1:15, 2 °, of the Companies and Associations Code. Belgian Anchorage SCRL therefore has no other indirect participation in IBA SA to be notified under article 6, §5, paragraph 1, 2 °, of the law of 2 May 2007 (article 9, § 3, 2 °, of the same law).

• Additional Information

1. Passive threshold crossing (article 6, §3, of the law of May 2, 2007) is the consequence of the change of denominator (total of existing voting rights) following the introduction of double voting rights in the articles of association of IBA SA during the EGM of March 10, 2020. The number of IBA shares held by Belgian Anchorage SCRL has not changed (it is still 6,204,668).

2. Belgian Leverage SA acquired on February 23, 2020 200,000 IBA shares held in its own right by IBA Investments SCRL. Belgian Leverage SA is the subsidiary of Belgian Anchorage SCRL, owned (directly) by the latter for 99.99% of its capital. Under article 11, §1, of the law of 2 May 2007, Belgian Leverage SA will not notify separately the acquisition of these 200,000 shares since these shares are taken over by its parent company in this notification.

3. Following the EGM of March 10, 2020 having voted the double rights, the denominator of IBA was modified and this notification of change of denominator was not published until April 30, 2020, this is why this date is repeated in point 7.
