Dividend Declaration

On the 9 April 2026, the Company announced that the Directors had declared a first and final dividend of €1.00 per Ordinary share for the year ended 31 December 2025.

The final dividend was approved by shareholders at the Annual General Meeting on Thursday, 21 May 2026. The dividend will be paid on Thursday, 16 July 2026 to holders of Ordinary shares on the register at the close of business on Friday, 26 June 2026 (ex-dividend date is 25 June 2026).

Following the reduction of capital that was made effective by the Company on 17 November 2025, the Company has created additional distributable reserves which can be used by the Company to deliver shareholder returns, including the approved final dividend. As the Company is tax resident in Greece, and for the purposes of Greek law 4172/2013 and Greek law 5162/2024, the final dividend is expected to be treated both for Greek corporate income tax purposes and for Greek withholding tax purposes as a return of share capital. Therefore, each shareholder should seek advice from their personal tax advisor regarding the tax treatment of any amounts received from the Company in their country of tax residence.
