The Record Date also applies in the event of a postponed or reconvened meeting provided that the postponed or reconvened meeting is not more than thirty (30) days from the Record Date. It is noted that in the event of a reconvened meeting, as per above, no new notice will be published pursuant to Article 130 of Law 4548/2018. If any postponed or reconvened meeting of the General Meeting is more than thirty (30) days from the Record Date, any person having the status of shareholder as per above at the beginning of the third (3rd) day prior to the day of the postponed or reconvened General Meeting is entitled to participate to the General Meeting.

Towards the Company, as shareholder entitled to participate and vote in the Annual General Meeting is considered any person registered, on the Record Date, in the records of the Dematerialized Securities System (the “DSS”) of the “EURONEXT SECURITIES ATHENS S.A. ” or any person identified as such based on the Record Date through registered intermediaries or other intermediaries, in line with the relevant legislative provisions (law 4548/2018, law 4569/2018, law 4706/2020 and Implementing Regulation (EU) 2018/1212) and the EURONEXT SECURITIES ATHENS Rulebook, as amended and in force.

Shareholders may participate in the Annual General Meeting through any confirmations or notices set out in articles 5 and 6 of Implementing Regulation (EU) 2018/1212 to provided by any intermediaries, unless the General Meeting denies the entitlement to attend and vote in the Annual General Meeting for good cause justifying such denial in accordance with the applicable provisions (article 19(1) of law 4569/2018, article 124(5) of law 4548/2018).

Each common, voting, dematerialized share grants one (1) voting right.

EXERCISE OF VOTING RIGHTS BY PROXY

Shareholders may attend and vote in the Annual General Meeting, in person or by proxy. Each shareholder, natural or legal person, may appoint up to three (3) proxies. However, if a shareholder holds shares of the Company that are registered in more than one securities accounts, the above limitation does not prevent the relevant shareholder from appointing different persons as proxies, for the purposes of the Annual General Meeting, regarding shares registered in different securities accounts. A proxy acting on behalf of more than one shareholders may vote differently for each shareholder.

Shareholders’ proxies are required to notify the Company, prior to the commencement of the session of the Annual General Meeting, of any specific event that may be useful to shareholders to assess the risk that the proxy may serve interests other than the interests of the represented shareholder. For the purposes of this paragraph, a conflict of interest may arise, in particular, where the proxy:

1. is a shareholder exercising control over the Company or is another legal person or entity controlled by such shareholder;
2. is a member of the Board of Directors or the management of the Company in general or of a shareholder exercising control over the Company, or of another legal person or of an entity that is controlled by a shareholder exercising control over the Company;
3. is an employee or auditor of the Company or of a shareholder exercising control over the Company, or of any other legal person or of an entity that is controlled by a shareholder exercising control over the Company; and
4. is a spouse or a first degree relative with one of the natural persons referred to under items (a) to (c) above.

The appointment and revocation or the replacement of a shareholder's proxy takes place in writing and is notified to the Company, in observing the same formalities, at least forty-eight hours (48) hours before the date of the session of the Annual General Meeting.

The Company has made available on its website (www.sidma.com) in the section “Investor Information
