Conditions for participation and exercising voting rights at the general meeting:

BSE requests shareholders' identification from KELER Központi Értektár Zartkörűen Működő Reszvénytársaság (hereinafter: KELER Zrt.) for the date of the General Meeting (including the rescheduled general meeting) as a corporate event. The record date of the shareholders' identification shall be 10 October 2025. The rules of the shareholders' identification are contained in the regulations of KELER Zrt.

On the second working day before the day of the General Meeting (including the rescheduled general meeting), i.e. on October 15, 2025 at 6:00 p.m., BSE will delete all the data in the share register based on the

shareholder's identification carried out for the above record date, and at the same time registers the data corresponding to the result of the shareholder's identification it in the share register, closes the share register, and does not complete a registration request until the day after the General Meeting has been convened.

In line with the relevant provisions of law, only those persons may exercise shareholder's rights at the general meeting (participation in the general meeting, requesting information within the limits specified in the relevant laws, making remarks and proposals and voting) whose name is registered in the Share Register at 6.00 p.m. on 15 October 2025.

The securities account managers shall be responsible for registering the shareholders in the Share Register upon instruction of such shareholders. The securities account managers shall provide information to the shareholders on the deadlines for giving instructions to the securities account managers.

Shareholders may inspect and obtain information in respect of their registration in person (1074 Budapest, Rákóczi út 70-72., R-70 Office Building) - at the time as agreed previously via e-mail kelertesem@keler.hu after identification. Closing the Share Register does not restrict the right of the persons registered in the Share Register to transfer their shares following the closing date. Transferring shares prior to the general meeting does not deprive the persons registered in the Share Register of their rights to participate in the general meeting and exercise their rights they are entitled to as shareholders.

We call the shareholders attention to that in accordance with Art. 355, Paragraphs (3)-(4) of Law CXX of the year 2001, on Capital Markets (CMA), the identifying data on indirect holdings in the BSE of shareholders with at least five per cent of the shares shall be also recorded, as an annex to the shareholders' register of the BSE. Shareholders having or acquiring a five per cent or higher ownership stake in the BSE are obligated to report this, (with the simultaneous disclosure of their identifying data), to the registrar of the shareholders' register. The shareholder who fails to comply with this reporting obligation shall not be allowed to use his/her voting rights until the fulfilment of this obligation.

In case the share has several holders and the joint representative has been registered in the shareholder's register, the joint representative exercises the shareholder's rights at the general meeting.

The general meeting shall have a quorum if the holders of shares representing more than half of the voting rights are present. One share with a nominal value of HUF 100 (i.e. One Hundred Hungarian forints) entitles the shareholders to one vote.

Participation in person, through or through a proxy issued or by nominee:

The General Meeting will be held with the personal appearance of those entitled to participate. Shareholders shall be entitled to participate in the general meeting either in person or through a proxy issued or by nominee in accordance with the provisions of the Civil Code and the CMA. BSE or its representative checks the identity of the shareholder, their representative and/or proxy based on documents before admission to the General Meeting.

The shareholder can also give a power of attorney on a form, the form can be found on the BSE's website (https://bse.hu/investor-relations).

The power of attorney for the nominee shall be prepared in the form of a public document or a private document with full probative force taking into account any international agreement or reciprocity between Hungary and the country where the document was issued. If the power of attorney is prepared in any language other than Hungarian a certified Hungarian translation thereof shall be attached.

A representative may represent several shareholders, however, they must have the power of attorney corresponding to the above for each represented shareholder.

The auditor cannot be an authorized representative, however - differently to the provisions of Section 3:255.(1) of the Civil Code - the member of the board of directors, the CEO, the company manager, the manager of the joint-stock company and the member of the supervisory board can act as an authorized representative on behalf of the shareholder. A representative can represent several shareholders, and a shareholder can authorize a separate representative for each securities account. If the shareholder is represented by several

representatives, and they vote or make statements differently from each other, the vote cast or the statement made by all of them is considered null and void. The power of attorney may be valid for a general meeting or for a specified period of time, but not more than twelve months. The power of attorney covers the continuation of the suspended general meeting and the rescheduled general meeting convened due to the lack of a quorum.

The right of representation of persons acting on behalf of shareholders who are not natural persons must be verified with an original document from a public register (e.g. company extract, court extract) dated no older than 30 days from the date of the general meeting.
