A. Right to participate and vote in the General Meeting

The Annual General Meeting of the shareholders of the Company on 25th of June 2026 will be held in a hybrid format and shareholders (or proxies) will have the opportunity to choose how they wish to participate (in person or by electronic means), to vote on the items of the agenda and submit questions as described below (see B(c)). In the same way, the persons of par. 1 and 2 of article 127 of Law 4548/2018 may also be present at the General Meeting.

Any person who has the shareholder capacity at the beginning of the fifth (5th) day before the date of the Annual General Meeting, i.e., at the beginning of the 20th June 2026 ("Record Date"), may participate in the General Meeting. Each ordinary share of the Company is entitled to one (1) vote.

Any person registered as a shareholder of the Company on the Record Date at the Dematerialized Securities System (“DSS”) of the EURONEXT SECURITIES ATHENS S.A. (former “Hellenic Central Securities Depository S.A.”), or identified as such, on the Record Date, via registered intermediaries or other intermediaries in compliance with the provisions of the relevant legislation (Law 4548/2018, Law 4569/2019, Law 4706/2020 and Regulation (EU) 2018/1212) including the Operation Regulation of the ATHEXCSD (Governmental Gazette B /1007/16.03.2021), is considered as shareholder vis-à-vis the Company and is entitled to participate and vote in the General Meeting.

The shareholding status can be verified by any lawful means and, in any case, based on the information received by the Company from EURONEXT SECURITIES ATHENS S.A. or through participants and registered intermediaries in the central securities depository, in the event that the shares are held in an omnibus account. A shareholder may attend the General Meeting based on the confirmations or notifications as specified in articles 5 and 6 of Regulation (EU) 2018/1212, which are provided by the intermediary, unless the meeting refuses such participation for serious reasons justifying such refusal in accordance with the applicable provisions (art. 19 par.1 Law 4569/2019, art. 124 par.5 Law 4548/2018).
It is noted that the exercise of the aforementioned rights (participation and voting) does not involve the blocking of shares or any other similar process that would restrict the right to sell or transfer such shares during the period between the Record Date and the day of the General Meeting.

B. Participation and Voting procedure at the General Meeting

a)    By appointment of proxy

Shareholders may participate and vote in the General Meeting by proxy holders. Each shareholder may appoint up to three (3) proxy holders. However, if a shareholder holds shares of the Company, that appear in more than one securities account, the shareholder may appoint different proxy holders for each of the securities account, where the shares are held with respect to the General Meeting. A proxy holder acting on behalf of more than one shareholders may cast votes differently for each shareholder, according to written voting instructions provided to them. Legal entities participate in the General Meeting by appointing up to three (3) individuals as their representatives. The shareholder may appoint a proxy holder either for a single General Meeting or for a number of General Meetings taking place within a specified time period. The proxy appointment is freely revocable.

In particular, with respect to the participation of the shareholder (or the Participant of the Securities Account of the DSS or another’s intermediary acting as a custodian for the shareholder) through proxy remotely in real time by teleconference in the Annual General Meeting of the 25th June 2026, and in case of appointment of more than one proxy holders, the details of the first appointed proxy holder will be taken into consideration for identification purposes.

The proxy holder votes in accordance with the shareholders’ instructions, where such instructions exist, and is required to keep the voting instructions on file for at least one (1) year from the date of the General Meeting.

The proxy holder is obliged to disclose to the Company, prior to the start of the General Meeting, any event which may be useful to the shareholders in assessing the risk of the proxy holder serving any interest other than the interest of the represented shareholder. A conflict of interest shall be deemed to arise, in particular, in circumstances where the proxy holder:

(i) is a controlling shareholder of the Company, or constitutes an entity controlled by such a shareholder; 
(ii) serves as a member of the Board of Directors or of the management of the Company, or of a controlling shareholder or of any other subject to the control of such controlling shareholder; 
(iii) is an employee or a certified auditor of the Company, or of a controlling shareholder or of an entity subject to the control of such shareholder;

For the convenience of the shareholders, the Company has designated certain executives to whom shareholders may, at their discretion, grant a proxy authorizing such executives to represent them and cast votes on their behalf at the General Meeting in accordance with their duly submitted written voting instructions.
