To promote the broad participation of Shareholders, the OEGM will be held exclusively digitally, so that the Shareholder may participate through:

Participation via Digital Platform

The shareholders who intent to participate or vote in the OEGM, via the Digital Platform, must obligatorily register on the website https://qicentral.precisao-i.com/m/agoe-eletrobras-2025 and submit all the documents required for qualification[1] by 11:59 p.m. on April 27,2025, subject to the other deadlines, conditions and procedures set forth in the Management Proposal published on this date.

In case of shareholder representation by proxy, in addition to submitting the documents proving the shareholder's status and representation, the proxy must register their data on the website https://qicentral.precisao-i.com/m/agoe-eletrobras-2025 and, through this platform, indicate each shareholder they will represent, observing the other deadlines, conditions and procedures set forth in the Management Proposal published.

In the event of insufficient documentation, the shareholder must complete it on the same website https://qicentral.precisao-i.com/m/agoe-eletrobras-2025, by 11:59 p.m. on April 27, 2025. No additional deadline will be given for remedying insufficient documentation.

If an accredited shareholder does not receive confirmation of virtual access to the OEGM up to eight (8) hours before the start of the OEGM, they must contact the Company's Investor Relations department by e-mail assembleiavirtual@eletrobras.com up to four (4) hours before the start of the OEGM.

Participation via BVD

Under the terms of RCVM 81, shareholders, within the period of up to four (4) days prior to the OEGM, that means up to 11:59 p.m. on April 25, 2025, may exercise their vote remotely by transmitting the instructions for filling in the BVD to one of the following recipients: (a) the bookkeeping agent for the shares issued by the Company, Itaú Corretora de Valores S.A.; (b) its custody agent which provides this service, if the shares are deposited with a central depositary; (c) the central depositary; or (d) directly to the Company.

The BVD will be considered invalid and will not be processed by the Company if it is submitted without the required documentation to prove the shareholder or proxy status and/or if it is submitted after the deadline of four (4) days before the OEGM.

Until the deadline for submission has expired, the BVD may be corrected and resubmitted by the shareholder to the Company, in compliance with the procedures and other deadlines set forth in RCVM 81, provided that no BVD will be accepted after the deadline has expired. If there are any items not completed after the expiry of the four (4) day period preceding the OEGM, the Company will consider them as instructions equivalent to abstaining from voting.

Information on the requirements for appointing members to the Board of Directors and the Fiscal Council, the election process and filling in the BVD

The election of the members of the Board of Directors and, if installed, of the Fiscal Council will be carried out by vote for candidate(s), observing the possibility of adopting the multiple vote for the election of the Board of Directors, as well as the separate election by preferred shareholders of one member for the Board of Directors and another for the Fiscal Council, if there is a valid request under current legislation.

If the Extraordinary Shareholders' Meeting called for April 29, 2025, at 1:00pm, approves the matter relating to the Conciliation Agreement with the Federal Government (“EGM Conciliation”), the number of vacancies for ordinary shareholders will be automatically reduced (i) from nine (9) to six (6) for the Board of Directors; and (ii) from four (4) to three (3) for the Fiscal Council, assuming that the number of vacancies will be fixed at five (5).

Nominations of candidates for the Board of Directors and/or the Fiscal Council, whether or not they are included in the BVD, must fulfill all applicable legal and statutory requirements.

It is essential that the Shareholders consult the guidelines on nominating candidates and filling in the BVD with regard to the election of members of the Board of Directors and the Fiscal Council. There are different possible scenarios depending on the outcome of the Conciliation Agreement between the Company and the Federal Government, which may directly impact the vote. Detailed instructions can be found in the Management Proposal available on the Company's websites (https://ri.eletrobras.com/), CVM (https://sistemas.cvm.gov.br/) and B3 (https://www.b3.com.br/pt_br/).

It is recommended that requests for the adoption of multiple voting be submitted as far in advance as possible, in order to facilitate their processing by the Company and enable the participation of other shareholders.

Requests for the adoption of multiple voting for the election of members of the Board of Directors may be made through the BVD or sent directly to the Company's Investor Relations department via email at assembleiavirtual@eletrobras.com.
