Legal entities participate in the General Meeting through their representatives in accordance with the provisions set forth in Section IV below. Legal entities must, within the deadline specified in Section IV below, submit their documents of incorporation in accordance with the law, unless these have already been filed with the Company, in which case it is sufficient to indicate in the proxy document where they have been submitted.

II. Procedure for participation and voting at the General Meeting, remotely in real time, via teleconference

the General Meeting by mail-in ballot. Specifically, shareholders who wish to participate remotely in the voting on the items of the General Meeting to be held prior to the general meeting may make use of this option:

(a) Either by exercising their voting rights prior to the General Meeting via the online platform on which they have previously created an account and successfully registered as described above, during the period from 26.06.2026 at 9:00 until 16:00,

(b) or by completing and submitting to the Company the "Mail-in Ballot Form," which the Company will make available on its website:

https://qualco.group/shareholdersinformation/

This form must be sent to the Company fully completed 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 [email protected] with the subject line "Mail-in Voting Form – Annual General Meeting 06/30/2026" and, if it does not bear an electronic signature, the original must be sent to the Investor Relations & Shareholder Services Department at its offices at 66 Kifissias Avenue, Marousi, Athens, 151 25. The Company must receive the above Postal Voting Form via the above methods by 18:00 local time of 26.06.2026.

(c) or participate based on confirmations or notifications under Articles 5 and 6 of Regulation (EU) 2018/1212 provided by intermediaries.

Shareholders who vote in accordance with the above prior to the general meeting are counted toward the quorum and majority only if the relevant votes have been received by 18:00 local time of 26.06.2026.

It is noted that shareholders wishing to appoint proxies to participate remotely in the voting on the items of the General Meeting to be held 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, as specifically stated below. After this deadline, participation through a proxy in the voting to be held prior to the General Meeting will not be possible.

II. In the event that the quorum required by law and the Articles of Association for the discussion and decision-making on the above matters is not achieved, at the repeat Annual General Meeting on 07.07.2026, the right to participate in the General Meeting remotely by mail-in ballot must be exercised again in a vote to be held prior to the repeat General Meeting, using the same methods as those described above. The deadline for exercising the right to vote in this case, whether through the online platform or by submitting the postal vote form, is so that shareholders are counted toward the formation of a quorum and majority, no later than twenty-four (24) hours prior to the date of the repeat general meeting.

For any Repeat General Meeting on 07.07.2026, shareholders who did not appoint a proxy at the initial general meeting or shareholders who wish to replace the proxy they had appointed,

QUALCO
Group

in order to participate remotely in the voting to be held 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, as specifically stated above.

After this date, it will not be possible to participate through a proxy in the voting to be held prior to the Repeat General Meeting.

Shareholders are requested to ensure that the proxy appointment form and mail-in ballot have been successfully submitted and may call the following number for this purpose: +30 210 4446093 (Investor Relations & Shareholder Services Department).

IV. Exercising the right to vote through a proxy

Any person entitled to participate in the General Meeting as described above may also participate through proxies. Each person entitled to participate may appoint up to three (3) proxies. This limitation applies per securities account; that is, if a shareholder holds shares of the Company that appear in more than one securities account, this restriction does not prevent the shareholder from appointing up to three (3) proxies for the shares appearing in each securities account in connection with a specific general meeting. A proxy acting on behalf of multiple eligible participants may cast a different vote for each of them.

However, specifically for participation in the Annual General Meeting of June 30, 2026, or in its adjourned session 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 set forth in Section IV below. The grant of proxy is freely revocable.

A person entitled to participate may appoint a proxy for a single general meeting or for all meetings held within a specified period. The proxy shall vote in accordance with the instructions of the principal, if any, and shall retain the voting instructions for at least one (1) year, from the date of the general meeting or, in the event of its postponement, the last rescheduled meeting at which the proxy was exercised. The proxy's failure to comply with the instructions received does not affect the validity of the general meeting's resolutions, even if the proxy's vote was decisive in their adoption.

The proxy holder is required to disclose to the Company, prior to the commencement of the general meeting, any specific facts that may be useful to shareholders in assessing the risk that the proxy holder may serve interests other than those of the shareholder. For the purposes of this paragraph, a conflict of interest may arise in particular where the proxy:

(a) is a shareholder exercising control over the Company or another legal person or entity controlled by that shareholder,

QUALCO

(b) is a member of the Board of Directors or the general management of the Company or of a shareholder exercising control over the Company, or of another legal person or entity controlled by a shareholder exercising control over the Company;

c) is an employee or auditor of the Company or of a shareholder exercising control over it, or of another legal person or entity controlled by a shareholder exercising control over the Company,

(d) is the spouse or a first-degree relative of one of the natural persons referred to in cases (a) through (c) above.

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

The notification of a representative, the appointment of a representative or proxy, and the revocation thereof shall be made only in writing and submitted to the Company forty-eight (48) hours prior to the scheduled date of the General Meeting by submitting the document, signed and certified for the authenticity of the signature by the representative or Shareholder, to the Investor Relations & Shareholder Services Department at the Company's headquarters (66 Kifissias Avenue, Marousi, 15125, Attica) or, in the case of shareholders identified through intermediaries, via confirmations or notifications pursuant to Articles 5 and 6 of Regulation (EU) 2018/1212.

Upon receipt of the above information by the Company and based on the email address (email) and mobile phone number of the representative or proxy, as stated in the representative or proxy appointment form, the Company creates an account for the representative or proxy on the electronic platform, who will be notified via email to activate their account so that they may exercise their shareholder rights in accordance with the above.

If the person entitled to participate has not complied with the above requirements regarding the notification of a representative or the appointment of a representative or proxy and the submission of the relevant supporting documents to the Company, as set forth below, the person is entitled to participate in the General Meeting only upon authorisation by the General Meeting.

A proxy form for the appointment of a proxy and a proxy notification form that may be used by shareholders, as applicable, will be made available on the Company's website, https://qualco.group/shareholders-information/.

Those entitled to participate are requested to ensure that the proxy appointment form has been successfully submitted and received by the Company by calling the Investor Relations & Shareholder Services Department at +30 210 4446093.
