a. Right to Participate and Vote in the General Meeting: Any shareholder having this capacity at the Record Date, as defined hereinbelow is entitled to participate and vote in the General Meeting. Each share of the Company gives the right to one (1) vote in the General Meeting.

At the date of this invitation the Company's capital is divided into 107.222.688 common shares incorporating 107.222.688 voting rights in total. Whoever appears to be a shareholder in the records of the Dematerialized Securities System (DSS), managed by the "Hellenic Central Securities Depository SA"(ATHEXCSD) where the securities (shares) of the Company are kept, is entitled to participate in the General Meeting. The capacity of the shareholder must exist at the beginning of the fifth (5th) day prior to the date of the General Meeting of 13 June 2024, i.e., at the beginning of 8 June 2024 (the "Record Date"). The above Record Date is also valid in case of postponed or repeat meeting, provided that such postponed or repeat meeting is not more than thirty (30) days away from the Record Date. The shareholder capacity at the Record Date will be proved through the Company's direct electronic linkup with the records of the DSS. In case of non-compliance with the provisions of article 124 of Law 4548/2018, said shareholder shall attend the General Meeting only if the General Meeting allows it. It is hereby noted that the exercise of said participation and voting rights does not require the block of the beneficiary's shares nor the observance of any other similar procedure, which limits the freedom to sell and transfer shares during the period between the Record Date and the date of the General Meeting.

In case the required quorum is not ascertained, with regard to the items of the agenda, the shareholders are invited on 2 July 2024, day of the week Tuesday at 16:00 p.m. at the Company's seat, in Municipality of Kallithea, Attica and, more specifically, in the office building of its subsidiary company under the name "Uni Systems S.M.S.A." at 19-23 Al.

At the Repeat General Meeting, which as results from the above is not more than thirty (30) days away from the Record Date, are entitled to participate and vote the Shareholders who have the right to participate at the beginning of 8 June 2024 (Record Date). b. Procedure for voting through proxy/ies:

Every shareholder attends the General Meeting and votes either in person or through proxies. Each shareholder may appoint up to three (3) proxies. However, if the shareholder holds Company's shares that appear in more than one securities' accounts, this limitation does not prevent the shareholder from appointing different proxies for the shares that appear in each securities account in relation to the General Meeting. A proxy that acts on behalf of more than one shareholders may vote differently for every shareholder. Legal entities participate in the General

Meeting by appointing up to three (3) natural persons as their proxies. The shareholder may appoint a proxy for a single general meeting or for all meetings that take place within a certain period of time. The proxy votes in accordance with the instructions of the shareholder, if any, and is obligated to file the voting instructions for at least one (1) year, from the date of the General Meeting, or in case of its postponement, of the last repeat meeting in which he used his/her power of attorney. The proxy is obligated to disclose to the Company before the commencement of the General Meeting every specific fact, which could be useful to shareholders in order to evaluate the risk of the proxy serving interests other than the shareholder's interests. Conflict of interest may arise mainly in cases when the proxy is: a) a shareholder that exercises the control of the Company or another legal entity or an entity controlled by that shareholder, b) a member of the Board of Directors or of the management of the Company or of a shareholder controlling the Company, or of another legal entity or of an entity controlled by a shareholder controlling the Company, c) an employee or certified auditor of the Company or of a shareholder controlling the Company, or of another legal entity or of an entity controlled by a shareholder controlling the Company, d) the spouse or a relative of first degree of one of the natural persons mentioned in cases (a) to (c). The appointment and revocation of the shareholder's proxy is done in writing or electronically and is notified to the Company, at least three (3) days prior to the scheduled date of the General Meeting. The Company has made available on its website (www.quest.gr) on the internet, the form used for the appointment of a proxy. The aforementioned form, completed and signed, must be submitted by the shareholder to the Company Offices, at 2A Argyroupoleos - Kallithea Attica (Shareholder Services, contact person Mr. Dimitrios Papadiamantopoulos) or must be emailed to ir@quest.gr at least three (3) days prior to the date of the General Meeting or any Repeat Meeting. The shareholder is required to confirm the successful dispatch of his proxy appointment form and its receipt by the Company, by calling: 211 999 4762.
