Threshold Crossing by Bpifrance at ABIONYX PHARMA

On October 3, 2025, Bpifrance announced that it had indirectly crossed the 5% voting rights threshold in ABIONYX PHARMA. Through Bpifrance Participations, the organization now holds 1,508,906 shares, representing 4.32% of the capital and 3.54% of the voting rights in ABIONYX. This change results from the cancellation of double voting rights following the transfer of ABIONYX shares to bearer form.

It should be noted that EPIC Bpifrance does not directly hold any shares. The change in shareholding follows the application of Article 223-11 of the AMF General Regulation, which is relevant when double voting rights are destroyed.
