15. Earnings per Share

Basic earnings per share (EPS) is calculated by dividing into the profit attributable to equity holders of the parent by the weighted average number of common shares issued net of the treasury shares held by the Group and the vested awards under the 2012-2021 incentive plan (as of December 31, 2020 and 2019).

As of December 31, 2021 the weighted average number of shares for diluted earnings per share was increased to take into consideration the theoretical effect of potential ordinary shares that would be assigned to the beneficiaries based on the Group’s equity incentive plans (see Note 31 for further details on the equity incentive plans). There is no dilution impact as of December 31, 2020 and 2019, resulting in basic and diluted earnings per share being the same.

The Shareholder’s meetings held on March 4, 2021 and on July 1, 2021 approved respectively, two different share splits, as explained also in Note 27. The number of ordinary shares outstanding has been retrospectively adjusted as if such events had occurred at the beginning of the earliest period presented.
