III. RECORD DATE AND REQUIREMENTS FOR PARTICIPATION IN THE ANNUAL GENERAL MEETING

The entitlement to participate in the Annual General Meeting and to exercise the voting right and other shareholders' rights to be asserted in the context of the Annual General Meeting is based on the shareholding at the end of day on 5 April 2026 (12:00 midnight, CEST) (record date).

Only persons who are shareholders on the record date and can prove this to the Company shall be entitled to attend the Annual General Meeting.

For the proof of shareholding on the record date, a safe custody receipt pursuant to Section 10a AktG must be received by the Company no later than 10 April 2026 (12:00 midnight, CEST) exclusively by one of the following communication channels and addresses:

Shareholders are requested to contact their depositary bank and arrange for the issue and transmission of a deposit certificate.

The record date has no effect on the saleability of the shares and has no bearing on dividend rights.

Deposit certificate pursuant to Section 10a of the Austrian Stock Corporation Act (AktG)

The deposit certificate must be issued by the depositary bank having its registered office in a member state of the European Economic Area or in a full member state of the OECD and must contain the following information (Section 10a Para. 2 AktG):

• Information on the issuer: name/company name and address or a code commonly used in communications between credit institutions (SWIFT code),
• Information on the shareholder: name/company name, address, date of birth for natural persons, and, where applicable, register and register number for legal entities,
• Custody account number, securities account number or other designation,
• Information on the shares: number of shares held by the shareholder, ISIN AT0000APOST4 (international securities identification number),
• The date or period of time to which the deposit certificate refers.

The deposit certificate as evidence of the shareholding and as basis for participation in the Annual General Meeting must refer to the end of the record date of 5 April 2026 (12:00 midnight, CEST).

The deposit certificate will be accepted in German or English.

Proof of identity

Shareholders and their proxies are requested to present a valid official photo ID for identification purposes at the registration.

If you come to the Annual General Meeting as a proxy, please take the proxy authorisation with you in addition to your official photo ID. If the original of the proxy authorisation has already been sent to the Company, you can facilitate admission by presenting a copy of the proxy authorisation.

Österreichische Post Aktiengesellschaft reserves the right to establish the identity of persons appearing at the meeting. If it is not possible to establish the identity, admission may be refused.

IV. POSTAL VOTE

Every shareholder is entitled to participate in the upcoming Annual General Meeting on the basis of voting by mail in accordance with Section 19 of the Articles of Association and Section 127 AktG.

The submission of votes must be done in written form by using the form (ballot) provided by the Company. The documents for the postal vote (ballot form, revocation form, instruction sheet, return envelope) will be sent upon request. Please request these by e-mail to investor@post.at or by telephone from the Investor Relations Department at +43 (0) 57767 – 30400 at the following times: Monday – Thursday 9:00 a.m. – 4:00 p.m. and Friday 9:00 a.m. – 1:00 p.m. The texts of the forms and the information sheet will be available on the Company’s website at post.at/investor under the menu item “Annual General Meeting” no later than 25 March 2026.

The shareholder must provide the following information on the form (ballot) in any case: name (company) and place of residence (registered office) of the shareholder and the number of shares. Ballots are only considered to be valid if signed by the shareholder.

The completed form (ballot) with the original signature must be received by the notary public Mr. Rupert Brix at his P.O. Box 29, 8230 Hartberg, Austria, as the authorised delivery agent of Österreichische Post Aktiengesellschaft for the purpose of postal voting, no later than 10 April 2026.

It is expressly pointed out that the prerequisite for postal voting is the proof of share ownership on the record date (5 April 2026), i.e., the Company receives a deposit certificate pursuant to Section 10a AktG at one of the above-mentioned addresses no later than 10 April 2026. Shareholders who want to take part in the Annual General Meeting by way of postal voting must ensure the timely issuance and transmission of a deposit certificate pursuant to Section 10a AktG as described above.

Shareholders are advised that votes submitted per absentee ballot by mail are void if the resolution at the Annual General Meeting is passed with a different content than that provided for in the form (ballot).

If necessary, the Company will provide a new form (ballot) on the Company's website at post.at/investor if admissible motions by shareholders to supplement the agenda within the meaning of Section 109 AktG are received no later than 25 March 2026 and/or admissible motions for resolutions by shareholders on the agenda items within the meaning of Section 110 AktG are received no later than 3 April 2026.

In case a vote has already been cast by mail, this vote may be revoked using the form (revocation) provided by the Company for this purpose on its website. For the revocation to be legally effective, it shall be sufficient if the revocation is received by notary Mr. Rupert Brix by fax at +43 (0) 1 512 46 11 – 28 no later than the end of the day on 14 April 2026.

If a shareholder appears at the Annual General Meeting who has already cast his/her vote by way of voting by mail, he/she may only exercise his/her voting right at the Annual General Meeting if he/she has revoked his/her vote in due time, i.e., no later than 14 April 2026 as described in more detail above. Otherwise, the shareholder may participate in the Annual General Meeting as a guest without the right to exercise the shareholders' rights, i.e., this shareholder has no right to speak or ask questions, no right to propose motions and in particular, no right to vote or to object.

A shareholder who has participated in the voting by mail may at the same time declare an objection to a resolution to be adopted at the Annual General Meeting as a precautionary measure on the voting form. There is no further possibility to object to the resolution.

V. POSSIBILITY OF APPOINTING A PROXY AND THE PROCEDURE TO BE FOLLOWED

Each shareholder who is entitled to participate in the Annual General Meeting and who has proved this to the Company in accordance with the provisions of this convening notice, section III, has the right to appoint a proxy to participate in the Annual General Meeting on behalf of the shareholder and who has the same rights as the shareholder whom he orshe represents.

The proxy authorisation must be granted to a specific person (a natural person or a legal entity) in text form (Section 13 Para. 2 AktG), whereby several persons may also be authorised.

The granting of a proxy is possible both before and during the Annual General Meeting.

We offer the following communication channels and addresses for the transmission of proxy authorisation:

Proxies must be received at one of the before mentioned addresses no later than 14 April 2026 (4:00 p.m., CEST), unless they are handed over at the entrance and exit control of the Annual General Meeting on the day of the Annual General Meeting.

A proxy form and a form for revoking the proxy are available on the Company's website at post.at/investor. In the interest of smooth processing, we ask for using only the forms provided.

Details on the authorisation, in particular on the text form and the content of the proxy, can be found in the proxy form provided to the shareholders.

If the shareholder has granted a proxy to his/her depository bank (Section 10a AktG), it shall be sufficient if, in addition to the deposit receipt, the depository bank submits a declaration to the Company by the means provided for its transmission to the Company that it has been granted a proxy.

Shareholders may exercise their rights in person at the Annual General Meeting even after granting a proxy. Appearance in person is deemed to be a revocation of a previously granted proxy.

The above provisions on the granting of proxy shall apply mutatis mutandis to the revocation of proxy.

Independent proxy

As a special service, a representative of the Interessenverband für Anleger (IVA), Feldmühlgasse 22/4, 1130 Vienna, will be available to shareholders as an independent proxy to exercise their voting rights at the Annual General Meeting in accordance with their instructions. IVA intends that Mr. Michael Knap will represent these shareholders at the Annual General Meeting. For authorisation of Mr. Michael Knap, a special proxy form will be available on the Company's website at post.at/investor from 25 March 2026 at the latest, which must be received by the Company exclusively at one of the above-mentioned communication channels (e-mail, post, fax, SWIFT) for transmission of proxies. Furthermore, it is possible to contact Mr. Michael Knap of the IVA directly via +43 (0) 664 213 87 40 or by e-mail at knap.post@hauptversammlung.at.

The shareholder must give instructions to Mr Michael Knap on how he (or, if applicable, a sub-proxy authorised by Mr. Michael Knap) is to exercise the voting rights. Mr. Michael Knap shall exercise the voting right exclusively on the basis of the instructions given by the shareholder. Without explicit instructions, the proxy is invalid. Please note that the proxy will not accept any instructions to make statements, to raise objections against resolutions of the Annual General Meeting, or to ask questions or to propose motions.

VI. NOTES ON THE RIGHTS OF SHAREHOLDERS PURSUANT TO SECTIONS 109, 110, 118 AND 119 AKTG

Each agenda item so requested must be accompanied by a proposal for a resolution and the reasons therefor. The agenda item and the proposed resolution, but not its justification, must in any case also be in German. The shareholder status shall be proven by the submission of a deposit certificate pursuant to Section 10a AktG, which confirms that the shareholders submitting the motion have been holders of the shares for at least three months prior to the submission of the motion and which may not be older than seven days at the time of submission to the Company. In the case of several shareholders who only together reach the required shareholding of 5 % of the share capital, the deposit certificates for all shareholders must refer to the same point in time (day, time). With regard to the other requirements for the deposit certificate, reference is made to the explanations on the right to participate (Section III.).

2. Proposals for resolutions by shareholders on the agenda pursuant to Section 110 AktG

Shareholders whose total shareholdings amount to 1 % of the share capital may submit proposals for resolutions on any item on the agenda in text form, together with a statement of reasons, and may request that these proposals, together with the names of the shareholders concerned, the statement of reasons to be attached and any comments by the Management Board or the Supervisory Board, be made available on the Company's website as entered in the commercial register, provided that this request is made in text form no later than 3 April 2026 (12:00 midnight, CEST), either to Österreichische Post Aktiengesellschaft, Attn: Investor Relations, 1030 Vienna, Rochusplatz 1, or by e-mail to investor@post.at, whereby the request is to be attached to the e-mail in text form within the meaning of Section 13 Para. 2 AktG, for example as a PDF file.

The proposed resolution, but not its reasoning, must in any case also be drafted in the German language.

In the case of a proposal for the election of a Supervisory Board member, the statement of the proposed person pursuant to Section 87 Para. 2 AktG shall replace the statement of reasons.

The shareholder status shall be proven by the presentation of a deposit certificate pursuant to Section 10a AktG, which shall not be older than seven days at the time of presentation to the Company. In the case of several shareholders who only together reach the required shareholding of 1 % of the share capital, the deposit certificates for all shareholders must refer to the same point in time (day, time).

With regard to the other requirements for the deposit certificate, reference is made to the explanations on the eligibility to participate (Section III.).

3.  Information pursuant to Section 110 Para. 2 (2) in conjunction with Section 86 Para. 7 and 9 AktG

With regard to agenda item 8 "Elections to the Supervisory Board" and the possible submission of a corresponding election proposal by shareholders pursuant to Section 110 AktG, the Company provides the following information:

Section 86 Para. 7 AktG is applicable to Österreichische Post Aktiengesellschaft.

Following the last election by the Annual General Meeting, the Supervisory Board of Österreichische Post AG consists of eight members elected by the Annual General Meeting (shareholder representatives) and four members delegated by the Works Council in accordance with Section 110 of the Austrian Labour Constitution Act (ArbVG). Of the eight shareholder representatives, three are men and five are women. Of the four employee representatives, three are men and one is a woman.

It is announced that the majority of the shareholders' representatives on the Supervisory Board raised an objection pursuant to Section 86 Para. 9 AktG more than six weeks before the Annual General Meeting and that the minimum quota requirement pursuant to Section 86 Para. 7 AktG will therefore be met separately.

Pursuant to Section 9 Para. 1 of the Articles of Association of Österreichische Post Aktiengesellschaft, the Supervisory Board consists of at least four and at most ten members elected by the Annual General Meeting and the members delegated by the Company's employee representatives pursuant to Section 110 Para. 1 Austrian Labour Constitution Act (ArbVG).

Should shareholders submit a proposal for election to agenda item 8 "Elections to the Supervisory Board", they must take into account that after the elections to the Supervisory Board on 15 April 20256 at least two women must be members of the Supervisory Board on the side of the shareholder representatives.

4.  Shareholders' right to information pursuant to Section 118 AktG

Each shareholder shall, upon request, be provided with information at the Annual General Meeting on the affairs of the Company to the extent that such information is necessary for the proper evaluation of an item on the agenda. The duty to provide information shall also extend to the legal relations of the Company with an affiliated company and to the situation of the Group and the companies included in the consolidated financial statements.

The information may be refused insofar as, according to reasonable business judgement, it is likely to cause significant disadvantage to the Company or an affiliated company, or its provision would be punishable by law.

Requests for information must generally be made orally at the Annual General Meeting but may also be made in writing.

Questions requiring longer preparation should, in the interest of the efficient conduct of the meeting, be submitted to the Management Board in good time before the Annual General Meeting in text form. The questions may be sent to the Company by e-mail to investor@post.at.

5. Motions proposed by shareholders at the Annual General Meeting pursuant to Section 119 AktG

Every shareholder is entitled – irrespective of a specific shareholding – to submit motions on any item on the agenda at the Annual General Meeting. If there are several motions on one item of the agenda, the Chair of the Supervisory Board shall determine the order of voting in accordance with Section 119 Para. 3 AktG.

However, a shareholder proposal for the election of a Supervisory Board member requires the timely submission of a resolution proposal pursuant to Section 110 AktG: persons for election to the Supervisory Board (item 8 on the agenda) may only be proposed by shareholders whose shares together amount to 1 % of the share capital. Such nominations must be received by the Company no later than 3 April 2026 in the manner set out above (Section VI. Para. 2). Each nomination must be accompanied by a declaration pursuant to Section 87 Para. 2 AktG of the nominee's professional qualifications, professional or comparable functions and any circumstances that could give rise to concerns of partiality.

Otherwise, the shareholder proposal for the election of a Supervisory Board member may not be considered in the vote.

Further information on the rights of shareholders pursuant to Sections 109, 110, 118 and 119 AktG will be available on the Company's website post.at/investor from 25 March 2026 at the latest.

6.  Information for shareholders on data processing

Österreichische Post AG processes personal data of shareholders in accordance with Section 10a Para. 2 AktG, i.e., name, address, date of birth, number of the securities account, number of shares held by the shareholder, class of shares, if applicable, number of the voting card and, if applicable, name and date of birth of the proxy, and on the basis of the applicable data protection provisions, in particular the European Data Protection Regulation (GDPR) and the Austrian Data Protection Act, in order to enable shareholders to exercise their rights at the Annual General Meeting.

The processing of personal data of shareholders is mandatory for the participation of shareholders and their representatives in the Annual General Meeting in accordance with the Austrian Stock Corporation Act (AktG). The legal basis for the processing is therefore Article 6 Para. 1 c) GDPR.

Österreichische Post Aktiengesellschaft is the responsible institution for the processing of data.

These service providers only receive personal data from Österreichische Post Aktiengesellschaft that is necessary for the performance of the commissioned service and process the data exclusively in accordance with the instructions of Österreichische Post Aktiengesellschaft. To the extent legally necessary, Österreichische Post Aktiengesellschaft has concluded a data protection agreement with these service providers.

If a shareholder participates in the Annual General Meeting, all shareholders present or their representatives, the members of the Management Board and the Supervisory Board, the notary public and all other persons with a legal right to participate may inspect the legally required list of participants (Section 117 AktG) and thereby also view the personal data listed therein (including name, place of residence, shareholding). Österreichische Post Aktiengesellschaft is also legally obliged to submit personal shareholder data (in particular the list of participants) as part of the notarial record for the Commercial Register (Section 120 AktG).

Further information on data privacy is contained in the Data Protection Policy on the Website of Österreichische Post Aktiengesellschaft at post.at/en/i/c/data-protection-business.
