On 08/30/2021, Management Anchorage SRL (BCE 0743.981.288, incorporated under the name "IB Anchorage") acquired 348,530 registered shares. In accordance with Article 28 of IBA SA's Articles of Association concerning double voting rights, Management Anchorage SRL has held 697,060 voting rights since 30/08/2023, i.e. 1.72%.

Shares with loyalty voting rights (article 28 of the Articles of Association): registered shares recorded in the register for at least two consecutive years in the name of their holder (see article 7:53 of the Companies and Associations Code).  Following the introduction of loyalty voting rights by decision of the General Meeting of March 10, 2020, the calculation method adopted by IBA to determine the number of shares with loyalty voting rights at any given time is the LIFO (last in, first out) method, i.e. for the same registered shareholder, the shares that the latter acquired most recently are the first shares to be deducted from his or her "portfolio” of registered shares if he or she subsequently sells shares.

Statutory transparency thresholds (article 35 of the bylaws): "In accordance with Article 18 of the Law of May 2, 2007 on the disclosure of major shareholdings in issuers whose shares are admitted to trading on a regulated market and containing various provisions, the notification obligation provided for in Articles 6 et seq. of this law applies to the crossing, upwards or downwards, of any minimum percentage of one percent (1%), two percent (2%), three percent (3%), four percent (4%), five percent (5%), seven point five percent (7. 5%), and at percentages of ten percent (10%), fifteen percent (15%) and so on in increments of five percent (5%), of the total voting rights outstanding at the time of the occurrence of the situation giving rise to the declaration under this law".
