Furthermore, based on articles 121 § 4, 124 § 6, 125, 126 and 128 of Law 4548/2018, the Company informs its shareholders of the following:

A. Right to Participate and Vote at the General Meeting

At the Ordinary General Meeting, any person, that has the status of shareholder at the start of the fifth (5th) day before the meeting date of the Ordinary General Meeting on April 14th , 2025, i.e. at the start of April 9 th , 2025 ("Record Date"), is entitled to participate. Each share of the Company gives the right to one (1) vote.

The as above Record Date is also valid in the event of a postponed or reconvened meeting provided that the postponed or reconvened meeting is not more than thirty (30) days from the Record Date as per article 124 § 6 of Law 4548/2018. It is noted that in the event of a Reconvened Meeting, a new invitation will not be published in accordance with the provisions of article 130 of Law 4548/2018. If any postponed or reconvened meeting of the 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 or reconvened General Meeting is entitled to participate.

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 société anonyme "HELLENIC CENTRAL SECURITIES DEPOSITORY S.A." ("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 Hellenic Central Securities Depository (Government Gazette Β/3178/05.06.2024).

The proof of the shareholder status is done by any legal means and in any case based on information received by the Company by ATHEXCSD or through the registered intermediaries in the central securities depository in case of keeping the shares in a omnibus securities account. 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 (article 19 § 1 Law 4569/2018, article 124 § 5 Law 4548/2018).

It is noted that exercising these rights (participation and voting) 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 date of the Ordinary General Meeting.

B. Participation and procedure for exercising the right to vote

Shareholders may participate and vote in the General Meeting either in person or by proxy.

Each shareholder or their representative may participate and vote in the General Meeting remotely.

(a) By appointing proxy:

Every shareholder has the right to attend the General Meeting and vote by proxy. Each shareholder may appoint up to three (3) proxies. However, if the shareholder possesses shares of the Company that are held in more than one Investor Securities Account, the above restriction cannot prevent the shareholder from appointing different proxies for the shares in each investor account in relation to the General Meeting. A proxy that acts for more than one shareholders can vote differently for each shareholder according to the written voting instructions provided to him. The shareholder may appoint a proxy for one or more General Meetings and for a specific period of time. The provision of proxy is freely revocable.

Specifically for shareholder participation by proxy at the General Meeting of April 14th , 2025 or any reconvened General Meeting, remotely in real time by teleconference, or for shareholder participation by proxy in the vote on the items of the General Meeting that will take place before the General Meeting, shareholders or Participants of the Securities Account in the DSS or other intermediaries acting as custodians of the shareholders through which the shares are kept, can appoint up to one (1) proxy, whose appointment must be made at least forty-eight (48) hours before the date of the General Meeting (i.e. the latest until 12.04.2025 at 14h00 for the initial General Meeting and the latest until 26.04.2025 at 14h00 for the Reconvened General Meeting). Ιn case of the appointment of more than one proxies, the details of the first declared representative/proxy will be taken into account for identification purposes.

Upon receipt of the above information by the Company and based on the email address and mobile phone number of the representative, as declared in the proxy document, the Company creates an account for the proxy on the electronic platform; the proxy is informed by email in order to activate the account so as to be able to exercise the rights of the shareholder.

The proxy votes in accordance with the shareholder's instructions, if there are any, and is obliged to file the voting instructions for at least one (1) year, from the date of the General Meeting. Non-compliance by the proxy with the instructions received does not affect the validity of the decisions of the General Meeting, even if the proxy's vote was decisive in achieving the majority.

The shareholder proxy is obliged to notify the Company, before the start of the General Meeting, about any specific event, which may be useful to shareholders in order to assess the risk that the proxy may serve other interests besides the interest of the shareholder. A conflict of interest may arise particularly when the proxy is:

• 1. a shareholder that exercises control of the Company, or other legal person or entity that is controlled by that shareholder;
• 1. a member of the Board of Directors or in general of the management of the Company or a shareholder that exercises control of the Company, or other legal person or entity that is controlled by that shareholder, which exercises control of the Company;
• 1. an employee or certified auditor of the Company or a shareholder that exercises control of the Company, or other legal person or entity that is controlled by that shareholder, that exercises control of the Company;
• 1. a spouse or a relative in the first degree of one of the private individuals that are mentioned in cases (1) to (3).

The appointment and revocation or replacement of the proxy of the shareholder takes place in writing and is notified to the Company, at least forty-eight (48) hours prior to the date of the General Meeting and in the case of shareholders that are identified through intermediaries, through confirmations or notifications of articles 5 and 6 of Regulation (EU) 2018/1212.

For the facilitation of the shareholders, the Company has specified certain persons whom the shareholders can, if they wish, authorize to represent them and vote for them at the General Meeting, in accordance with the written voting instructions they will give.

The Company shall make available on its website (www.aia.gr/investors), on the internet, the documents for the appointment and revocation or replacement of a proxy. The appropriate documents must be filled in, signed with the authenticity of the signature verified, and submitted by the shareholder to the Company's offices, at Administration Building 17, 190 19 Spata Attica, to the attention of the Shareholders Services and Corporate Announcements Department (contact person: Mr. Georgios Eleftheriou) or by e-mail at ir@aia.gr, at least fortyeight (48) hours before the General Meeting and no later than April 12th, 2025 at 14h00. Shareholders are asked to ensure that the proxy appointment and revocation or replacement documents are successfully dispatched and received by the Company at the telephone no. +30 210 3535000.

Shareholders that do not comply with the deadline in § 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 Ordinary General Meeting, unless the General Meeting refuses this participation for good reason which justifies this refusal in accordance with article 124 § 5 of Law 4548/2018.

(b) By mail vote before the General Meeting
