    If the quorum, as required by the Law and the Articles of Association in order to decide any of the items of the original agenda, is not obtained during the meeting of 13 June 2025, the General Meeting will convene again in a Repeat Meeting on Monday 23 June 2025 at 18:00 (hereinafter "Repeat Meeting") without the publication of a new invitation and will convene in the same way, i.e. hybrid, with the physical presence of shareholders at the registered office of the Company and with the participation of shareholders remotely by teleconference. 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.

    1. Right to participate and vote at the General Meeting

       At the General Meeting of 12 June 2025, every physical and legal person that has the status of shareholder at the start of the fifth (5th) day before the meeting date of the Annual General Meeting, i.e. on 7 June 2025 ("Record Date") is entitled to participate and vote.

       The record date of 7 June 2025 is the record date for the Repeat General Meeting on 23 June 2025 (if the quorum, as required by the Law and the Articles of Association in order to decide any of the items of the original agenda on 12.06.2025 is not obtained during that meeting). Also, the same Record Date is valid in case of the postponed General Meeting, provided that the postponed meeting is not more than thirty (30) days from the Record Date. If any postponed General Meeting is more than thirty (30) days away from the Record Date, whoever has the status of shareholder in accordance with the above at the beginning of the third (3rd) day before the day of the postponed General Meeting is entitled to participate in the General Meeting.

       For the Company, shareholders who are entitled to participate in the General Meeting and to exercise the right to vote are those that are registered on the Record Date in the Dematerialized Securities System (DSS) of the company "HELLENIC CENTRAL SECURITIES DEPOSITORY (ATHEXCSD)" or the one identified as such based on the relevant date through registered intermediaries or other intermediaries in compliance with the provisions of the legislation (Law 4548/2018, Law 4569/2019, Law 4706/2020 and Regulation (EU) 2018/1212) as well as the Rulebook of Operation of the Hellenic Central Securities Depository (Government Gazette B/1007/16.03.2021).

       The proof of shareholder status is done by any legal means and in any case based on information received by the Company until before the start of the General Meeting by ATHEXCSD or through the above intermediaries in accordance with the above provisions. A shareholder may participate in the General Meeting on the basis of confirmations or notifications of Articles 5 and 6 of Regulation (EU) 2018/1212 provided by the intermediary unless the Meeting refuses this participation for good reason that justifies its refusal in accordance with the provisions in force (art. 19 par. 1 of Law 4569/2018, art. 124 par. 5 of Law 4548/2018).

       Exercising these rights does not require either the blocking of the shares of the beneficiary or any other similar procedure which limits the ability to sell and transfer these shares during the period between the Record Date and the General Meeting.

       Shareholders that do not comply with the deadline in par. 4 of article 128 of Law 4548/2018, i.e. that do not submit in writing or by electronic means the appointment of proxies or representatives to the Company at least forty-eight (48) hours before the appointed date of the General Meeting, participate at the General Meeting unless the General Meeting refuses this participation for good reason which justifies this refusal.
