Sole Item of the Agenda: Election of new members of the Board of Directors.

I. Right to Participate in the General Meeting

Pursuant to article 124(1) of Law 4548/2018, only Shareholders of the Company who hold shareholder status at the beginning of the fifth day prior to the General Meeting, i.e. Friday, October 17, 2025 (the “Record Date”), are entitled to participate.

A shareholder entitled to participate and exercise voting rights is considered to be the one registered on the Record Date in the Dematerialized Securities System (DSS) of the company “Hellenic Central Securities Depository S.A.” (HCSD) or identified as such based on relevant data through registered intermediaries or other intermediaries in accordance with applicable legislation (Laws 4548/2018, 4569/2018, 4706/2020, Regulation (EU) 2018/1212) and the Operating Regulations of HCSD (Government Gazette B’/1007/16.03.2021).

It is noted that Shareholders’ participation in the General Meeting no longer requires blocking of shares or any other similar procedure that restricts their sale or transfer between the Record Date and the General Meeting.

II. Procedure for Exercising Voting Rights by Proxy

Shareholders entitled to participate may vote either in person or through proxies. Each Shareholder may appoint up to three (3) proxies. Legal entities may participate by appointing up to three (3) individuals as their representatives.

Proxy forms are available on the Company’s website www.elin.gr and at the Company’s Headquarters, 33 Pigon Street, 14564 Kifisia (Shareholders’ Services Department). The completed and signed proxy forms must be submitted and received at the Company’s Headquarters at least 48 hours before the General Meeting, i.e. by October 20, 2025, at 10:00 a.m.

A proxy representing more than one Shareholder may vote differently for each Shareholder. If a Shareholder holds shares appearing in more than one securities account, he/she may appoint different proxies for each account. A proxy may be appointed for a single General Meeting or for all meetings held within a specific period.

Proxies vote in accordance with the instructions of the Shareholder, if any, and must keep these instructions for at least one (1) year from the submission of the General Meeting’s minutes to the competent authority or, if the decision is subject to publication, from its registration in the General Commercial Registry.

A proxy is obliged to disclose to the Company before the start of the General Meeting any specific fact that may be useful for the Shareholders to assess the risk of serving interests other than those of the Shareholder. Conflict of interest may particularly arise when the proxy:
(a) is a controlling Shareholder of the Company or another legal entity controlled by such Shareholder,
(b) is a member of the Board of Directors or general management of the Company or of a controlling Shareholder or entity controlled by such Shareholder,
(c) is an employee or auditor of the Company or of a controlling Shareholder or entity controlled by such Shareholder,
(d) is a spouse or first-degree relative of any of the natural persons mentioned above.
