Earnings per share [abstract]  
Loss per share
Note 22. Loss per share

Accounting policy
Loss per share is calculated by dividing the net loss due to shareholders of the Company by the weighted average number of ordinary shares outstanding during the period.
The diluted loss per share is calculated by dividing the results by the weighted average number of common shares in circulation, increased by all dilutive potential common shares. The dilutive potential common shares include, in particular, the share subscription warrants, stock options, free shares, founder subscription warrants as detailed in Note 10 - Share Capital and Note 18 - Share-based payments.
Dilution is defined as a reduction of earnings per share or an increase of loss per share. When the exercise of outstanding share options and warrants decreases loss per share, they are considered to be anti-dilutive and excluded from the calculation of loss per share.

Instruments providing deferred access to capital are considered to be anti-dilutive because they result in a decrease in the loss per share. Therefore, diluted loss per share is identical to basic loss per share as all equity instruments issued but not granted, representing as of December 31, 2025, 4,985,304 potential additional ordinary shares, have been considered antidilutive.
