Item 5.

Interest in Securities of the Issuer

(a)

Item 5(a) of the Schedule 13D is hereby amended and supplemented as follows: As of the date hereof, (i) Bpifrance Participations holds directly 7,514,838 Ordinary Shares and 15,029,676 Voting Rights, and (ii) CDC Croissance held, through CDC PME CROISSANCE, 4,915,517 Ordinary Shares and 4,915,517 Voting Rights. As of the date hereof, none of Bpifrance, EPIC or CDC holds any Ordinary Shares directly. Bpifrance may be deemed to be the beneficial owner of 7,514,838 Ordinary Shares and 15,029,676 Voting Rights, indirectly through its 99.99% ownership of Bpifrance Participations. EPIC may be deemed to be the beneficial owner of 7,514,838 Ordinary Shares and 15,029,676 Voting Rights, indirectly through its joint ownership and control of Bpifrance. CDC may be deemed to be the beneficial owner of (x) 7,514,838 Ordinary Shares and 15,029,676 Voting Rights, indirectly through its joint ownership and control of Bpifrance, (y) 4,915,517 Ordinary Shares and 4,915,517 Voting Rights, indirectly through its ownership of CDC Croissance and (z) 1,111 Ordinary Shares and 1,111 Voting Rights, indirectly through its ownership of CNP Assurances. The ownership percentages are calculated based on 173,753,098 Ordinary Shares outstanding and 188,750,888 Voting Rights as of January 31, 2026, as reported by the Issuer. The voting rights outstanding have been revised to take into account any extinguished double voting rights from the sale of Ordinary Shares by Bpifrance Participations. The amount of outstanding Ordinary Shares and Voting Rights disclosed above is calculated under U.S. law, which requires treasury shares to be excluded from the calculation of outstanding shares. Under French law, treasury shares are required to be included in the calculation of outstanding shares. Using the French law requirements, the Issuer has 173,877,420 outstanding Ordinary Shares and 188,875,210 outstanding Voting Rights, and (i) Bpifrance Participations' Ordinary Share holdings represent approximately 4.3% of the Issuer's outstanding Ordinary Shares, and its Voting Rights represent approximately 8.0.% of outstanding Voting Rights, and (ii) CDC Croissance's Ordinary Share holdings represent approximately 2.8% of the Issuer's outstanding Ordinary Shares, and its Voting Rights represent approximately 2.6% of outstanding Voting Rights.
