Share Capital and Share Base Payments [Abstract]  
Capital CapitalShare capital
The Company manages its capital to ensure that the Company will be able to continue as a going concern while maximizing the return to shareholders through the optimization of the debt and equity balance.
As of June 30, 2026, the Company’s share capital amounted to €4,696,711 divided into (i) 93,921,863 ordinary shares, each with a nominal value of €0.05; (ii) 4,766 “2016” preferred shares, each with a nominal value of €0.05, and (iii) 7,581 “2017” preferred shares, each with a nominal value of €0.05, respectively, fully paid up.
Share capital does not include BSAs, BSAAR, AGAs and AGAPs that have been granted to certain investors or natural persons, both employees and non-employees of the Company, but not yet exercised.
On October 21, 2019 and December 30, 2019, the retention period for the “2016 free preferred shares” has ended. The number of ordinary shares to which the conversion of one preferred share entitle has been determined according to the achievement of the performance criteria. Holders of “2016” preferred shares” are entitled to vote at our shareholders’ meetings, to dividends and to preferential subscription rights, on the basis of the number of ordinary shares to which they are entitled if they convert their preferred shares.
In April 3, 2021, the retention period for the "2017 free preferred shares" has ended. The number of ordinary shares to which the conversion of one preferred share entitle has been determined according to the fulfillment of the performance criteria. According to these same performance criteria, the Executive Board of April 7, 2021 noted that the "2017 preferred shares" did not give right to any ordinary shares. The “2017 preferred shares” will not be redeemed by the Company and will remain incorporated into the capital, unless subsequently decided by the Executive Board. As the conversion is void, the "2017 preferred shares" no longer give the right to vote at our general meetings, nor to receive dividends.
