Basic and diluted earnings per share |
Basic and diluted earnings per share | 15 Basic and diluted earnings per share ​ Diluted earnings per share is calculated by adjusting the weighted average number of ordinary shares outstanding, assuming conversion of all potentially dilutive ordinary shares. As the Company has incurred a loss in the three and six months ended June 30, 2025, all potentially dilutive ordinary shares would have an antidilutive effect, if converted, and thus have been excluded from the computation of loss per share for the three and six months ended June 30, 2025. The ordinary shares are presented without giving effect to the application of the treasury method or exercise prices that would be above the share price as of June 30, 2025 and June 30, 2024, respectively. ​ The potentially dilutive ordinary shares are summarized below: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
