Dec. 31, 2025

Basic losses per share is calculated by dividing income (loss) attributable to equity holders of the Group by the weighted-

average number of outstanding ordinary shares for the year.

Diluted losses per share are calculated by adjusting the weighted average number of ordinary outstanding shares to assume

conversion of all dilutive potential ordinary shares.

Potential dilutive instruments (BCEs, BSAs, AGAs, BSA Kreos 1, OCEANE, Kreos/Claret BSA, Kreos/Claret OCABSA and

Height notes) have been excluded from the computation of diluted weighted-average shares outstanding because such instruments

had an antidilutive impact due to the losses reported. As of December 31, 2023, 2024 and 2025, the number of potential dilutive

instruments were 28,754,280, 29,570,132 and 8,857,084 respectively, giving rights to a maximum number of shares to be issued of
