I. Right to participate in the General Meeting

Any person who holds the status of shareholder at the beginning of the fifth (5th) day before the date of the initial session of the Extraordinary General Meeting, namely at the beginning of 13.12.2025 (the "Record Date"), shall be entitled to participate in the Extraordinary General Meeting (initial and repeat session). The above Record Date applies, also, in the case of an adjourned session as set out above. Proof of shareholding status may be provided by any lawful means. For the Company, a shareholder entitled to participate in the General Meeting and exercise the right to vote is the person registered on the Record Date in the Dematerialised Securities System (DSS) of the société anonyme "HELLENIC CENTRAL SECURITIES DEPOSITORY SOCIETE ANONYME" (ATHEXCSD) or the person identified as such based on the relevant date via registered intermediaries or other intermediaries, subject to the provisions of the legislation (Law 4548/2018, Law 4569/2019, Law 4706/2020 and Regulation (EU) 2018/1212) and the Operating Regulation of the Hellenic Central Securities Depository (Government Gazette B/6249/31.10.2023).

Proof of shareholding status is provided by any lawful means and, in any case, based on information received by the Company from the ATHEXCSD, if it provides registry services, or via participating and registered intermediaries in the central securities depository in all other cases. A shareholder may participate in the General Meeting based on confirmations or notices under Articles 5 and 6 of Regulation (EU) 2018/1212 provided by the intermediary, unless the meeting refuses such participation for a substantial reason justifying refusal, subject to applicable provisions (Article 19(1) Law 4569/2018, Article 124(5) Law 4548/2018).

The exercise of the rights to participate and vote in the General Meeting does not require the blocking of the shareholder's shares nor compliance with any other similar procedure which restricts the ability to sell and transfer such shares during the period between the Record Date and the date of the General Meeting.

Legal entities participate in the General Meeting through their representatives in accordance with the provisions under IV below. Legal entities must, within the deadline referred to under IV below, file their legal documentation in accordance with the law, unless such documents have already been filed with the Company, in which case it suffices to refer in the representation document to where these have been delivered.

III. Procedure for remote participation in the voting conducted prior to the General Meeting by postal vote

I. In accordance with Article 13(2) of the Articles of Association and Article 126 of Law 4548/2018, shareholders are additionally afforded the possibility to participate themselves or via their proxies remotely in the voting on the items of the General Meeting to be conducted prior to the General Meeting by postal vote. Specifically, shareholders who wish to participate remotely in the voting on the items of the Extraordinary General Meeting to be conducted prior to the General Meeting may exercise this right:

• (a) either by exercising their right to vote prior to the Extraordinary General Meeting via the Internet Platform in which they will have previously created an account and registered successfully as referred to above, during the period from Wednesday 17 December 2025 at 09:00 until 18:00.
• (b) or by completing and submitting to the Company the "Postal Vote Form," which the Company will make available on its website (https://qualco.group/shareholders-information/). This form must be sent to the Company completed in all its sections and signed by the person entitled to participate in the General Meeting, in accordance with the specific instructions for completion, signing and submission included therein, to the email address ir@qualco.eu with the subject "Postal Vote Form – Extraordinary General Meeting 18.12.2025" and, if it does not bear an electronic signature, its original must be sent to the Investor Relations & Shareholder Service Department, at the Company's offices at 66 Kifisias Avenue, Marousi, Athens, 15125. The Company must receive the above Postal Vote Form by the above means at least twenty-four (24) hours before the start of the session, i.e. by 17.12.2025 at 16:00;
• (c) or by participating on the basis of confirmations or notices under Articles 5 and 6 of Regulation (EU) 2018/1212 provided by intermediaries.

Shareholders who vote as above prior to the General Meeting are counted for the formation of the quorum and majority only if the relevant votes have been received by 16:00 on 17.12.2025.

It is noted that shareholders who wish to appoint proxies to participate remotely in the voting on the items of the General Meeting to be conducted prior to the General Meeting may appoint up to one (1) proxy, whose appointment must be made at least forty-eight (48) hours prior to the date of the General Meeting, namely by 16.12.2025 at 16:00, as specifically referred to below. After this deadline, participation via proxy in the voting to be conducted prior to the General Meeting will not be possible.

II. In the event that the quorum required under law and the Articles of Association to discuss and resolve upon the above items is not achieved, at the repeat Extraordinary General Meeting of 24.12.2025 the right to participate in the General Meeting remotely by postal vote must be exercised anew in voting to be conducted prior to the repeat Extraordinary General Meeting, by the same means as referred to above. The deadline for exercising the right to vote in this case, either via the Internet Platform or by sending the postal vote form, in order for shareholders to be counted for the formation of the quorum and majority, is at the latest twenty-four (24) hours prior to the date of the repeat General Meeting (i.e. by 16:00 on 19.12.2025).

For the repeat General Meeting of 24.12.2025, shareholders who had not appointed a proxy at the initial General Meeting or shareholders who wish to replace the proxy they had appointed, to participate remotely in the voting to be conducted prior to the repeat General Meeting, may appoint up to one (1) proxy, whose appointment must be made at least forty-eight (48) hours prior to the date of the repeat General Meeting (i.e. by 16:00 on 23.12.2025), as specifically referred to above.

After that date, participation via proxy in the voting to be conducted prior to the repeat General Meeting will not be possible.

The shareholder is requested to ensure confirmation of the successful dispatch of the proxy appointment form and the postal vote form and may for this purpose call: +30 210 4446093 (Investor Relations & Shareholder Service Department).

IV. Exercise of the right to vote via proxy

An entitled person as above may participate in the General Meeting via proxies. Each entitled person may appoint up to three (3) proxies. This limitation applies per securities account, i.e. if a shareholder holds shares of the Company which appear in more than one securities account, this limitation does not prevent the shareholder from appointing up to three (3) proxies for the shares appearing in each securities account in relation to a specific General Meeting. A proxy acting for more than one entitled person may vote differently for each of them.

However, specifically for participation in the Extraordinary General Meeting of 18.12.2025 or its repeat without physical presence via teleconference, the shareholder or the Participant of the Securities Account in the DSS or another intermediary acting as the shareholder's custodian through whom the shareholder's shares are held, may appoint only one (1) proxy, following the procedure under IV below. The grant of a power of attorney is freely revocable.

The entitled person may appoint a proxy for a single General Meeting or for any meetings held within a specified time period. The proxy votes in accordance with the instructions of the principal, if any, and files the voting instructions for at least one (1) year from the date of the General Meeting

or, in the event of adjournment thereof, from the date of the last repeat meeting at which the power of attorney was used. Non-compliance by the proxy with the instructions received does not affect the validity of the resolutions of the General Meeting, even if the proxy's vote was decisive for their adoption.

The proxy is obliged to disclose to the Company before the start of the General Meeting any specific fact that may be useful to shareholders for the assessment of the risk that the proxy may serve interests other than those of the shareholder. For the purposes of this paragraph, a conflict of interest may particularly arise where the proxy:

• (a) is a shareholder who exercises control of the Company or another legal person or entity controlled by that shareholder;
• (b) is a member of the Board of Directors or of the general management of the Company or of a shareholder exercising control of the Company or of another legal person or entity controlled by a controlling shareholder;
• (c) is an employee or auditor of the Company or of a shareholder exercising control of the Company or of another legal person or entity controlled by a controlling shareholder;
• (d) is a spouse or first-degree relative of one of the natural persons referred to in cases (a) to (c) above.

V. Notification of representative or appointment of representative or proxy or revocation thereof

Notification of a representative, appointment of a representative or proxy and revocation thereof must be made only in writing and submitted to the Company at least forty-eight (48) hours prior to the scheduled date of the General Meeting by filing the document, signed and with the signature's authenticity certified by the representative or shareholder, with the Investor Relations & Shareholder Service Department, at the Company's registered offices (66 Kifisias Avenue, Marousi, 15125, Attica) or, in the case of shareholders identified through intermediaries, via confirmations or notices under Articles 5 and 6 of Regulation (EU) 2018/1212.

Upon receipt of the above documentation by the Company and based on the email address and the mobile phone number of the representative or proxy, as declared in the representative or proxy appointment form, an account for the representative or proxy shall be created by the Company on the electronic platform, and the representative or proxy will be notified by email to proceed to activate their account so as to exercise the shareholder's rights as referred to above.

If the entitled person has not complied with the above provisions regarding the notification of a representative or the appointment of a representative or proxy and the sending of the relevant supporting documents to the Company, as provided below, they shall be entitled to participate in the General Meeting only after permission is granted by the General Meeting.

A proxy appointment form and a representative notification form which shareholders may use, as applicable, will be made available on the Company's website (https://qualco.group/shareholdersinformation/).

The entitled person is requested to ensure confirmation of the successful dispatch of the proxy appointment form and its receipt by the Company by calling the Investor Relations & Shareholder Service Department at +30 210 4446093.

particularly in the form of questions and answers. In all of the above cases, the Board of Directors may refuse to provide information for compelling material reasons, which shall be recorded in the minutes.

In the cases of this paragraph, the Board of Directors may provide a single reply to requests by shareholders with the same content.
