In accordance with Law 4548/2018, the Company informs its shareholders of the following:

A. RIGHT TO PARTICIPATE AND VOTE

Entitled to participate in the Extraordinary General Meeting is any person appearing as a shareholder in the records of the Dematerialised Securities System (DSS) managed by “Hellenic Central Securities Depository S.A.” (ATHEXCSD), in which the Company’s shares are registered.

Proof of shareholding status is established by the submission of a relevant written confirmation issued by the aforementioned institution or, alternatively, by the Company’s direct electronic access to its records.

The shareholder capacity must exist on 15 November 2025 (record date), i.e. at the beginning of the fifth (5th) day prior to the date of the General Meeting (20 November 2025), and the relevant confirmation or electronic verification regarding the shareholding must be received by the Company no later than 17 November 2025, i.e. the third (3rd) day before the Extraordinary General Meeting.

For the Reiterative Extraordinary General Meeting of 26 November 2025, the shareholder capacity must also exist as of 15 November 2025, since the reiterative meeting is held within thirty (30) days from the record date, pursuant to Article 124(6) of Law 4548/2018, while the relevant written confirmation or electronic verification must be received by the Company no later than 23 November 2025, i.e. the third (3rd) day prior to the reiterative Extraordinary General Meeting.

Only persons holding the capacity of shareholder as at the respective record date are entitled to participate and vote at the General Meeting. In the event of non-compliance with the provisions of Law 4548/2018, such shareholder may participate in the General Meeting only upon its permission.

It is noted that the exercise of the aforementioned rights (participation and voting) does not require the blocking of the shareholder’s shares nor any similar procedure restricting the ability to transfer or sell such shares between the record date and the date of the General Meeting. Each share entitles its holder to one (1) vote.
