2.          CALL NOTICE: The call notice was published, in accordance with article 124 of the Brazilian Corporation Law, in the newspaper “Valor Econômico”, on July 9, 10, and 11, 2025 (pages E3, C5, and E3, respectively).

3.          DISCLOSURES: All documents related to the matter to be resolved, as provided for in CVM Resolution 81, were made available to shareholders at the Company’s headquarters and on the worldwide web on the websites of the Company (http://ri.eletrobras.com), the CVM (http://cvm.gov.br) and B3 S.A. – Brasil, Bolsa, Balcão (http://b3.com.br).

4.          ATTENDANCE: The shareholder Federal Government was present, pursuant to the Conciliation Agreement entered into between the Federal Government and Eletrobras before the Câmara de Mediação e de Conciliação da Administração Pública Federal – CCAF/CGU/AGU, duly approved at the Company’s Extraordinary General Meeting held on April 29, 2025 (“Conciliation Agreement”), as verified by the attendance record provided by the Digital Platform, in accordance with CVM Resolution 81, thus establishing a quorum for installation regarding the agenda of the Meeting. Other shareholders did not qualify for participation via the Digital Platform. The Distance Voting Ballots (“BVDs”) received from other shareholders – other than the Federal Government – were treated as “disregarded votes”, as per Schedule I to these Minutes.

Also present were Mr. José Eduardo Guimarães Barros, General Legal Officer of Eletrobras, Ms. Carla Albano Miller, Head of Investor Relations, Mr. Bruno Klapper, Governance Officer, Mr. Francisco Duarte, Investor Relations Manager, and, for the purposes of article 164 of the Brazilian Corporation Law, Mr. Gisomar Marinho, member of the Company’s Fiscal Council.

5.          BOARD: Mr. Rodolfo Constantino de Tella, appointed by the Board of Directors, pursuant to article 18, §7, of the Bylaws, assumed the chairmanship of the proceedings, and Mr. Thiago Messina Coimbra and Ms. Raissa Camelo Lopez were invited to act as secretaries.

6.          AGENDA: According to the Call Notice and the Management Proposal disclosed for this Meeting, the agenda to be resolved is as follows:

6.1. To approve the election, in a separate voting process exclusive to the Federal Government, of Mr. Denilvo Morais, as an effective member of the Eletrobras Fiscal Council, as agreed in Conciliation Agreement No. 07/2025/CCAF/CGU/AGU-GVDM, approved by the shareholders at the Extraordinary General Meeting held on April 29, 2025.

7.          READING OF DOCUMENTS: The shareholder Federal Government waived the reading of the consolidated synthetic voting map of the votes cast by BVD, as it was already aware of it, which remained at its disposal, pursuant to §4 of article 48 of CVM Resolution 81, as well as the documents related to the matter to be resolved at this Meeting.

8.          RESOLUTIONS: After verifying the quorum for installation of the Meeting, the drafting of these minutes in summary form and their publication with omission of the signature of the shareholder Federal Government was authorized, as permitted by article 130, §§ 1 and 2 of the Brazilian Corporation Law.

8.1.      It was recorded that, as provided in the call documents and in accordance with what was stated at the end of item 8.1.18 of the minutes of the Ordinary and Extraordinary General Meeting of the Company held on April 29, 2025, the Meeting has a single matter: the separate election of the effective member of the Fiscal Council, of a strictly personal and exclusive nature of the shareholder Federal Government.

8.2.      Pursuant to Conciliation Agreement No. 07/2025/CCAF/CGU/AGU-GVDM and the Company’s Bylaws, the right to elect a member of the Fiscal Council by means of separate voting is exclusive, strictly personal, and non-transferable of the shareholder Federal Government. Thus, only the shareholder Federal Government could exercise the right to vote at the Meeting, including through the use of the BVD, and the transfer of this right to third parties, including other entities that are part of the Federal Government Shareholder Group, was prohibited. Consequently, all votes cast by any other shareholders – other than the shareholder Federal Government – were treated as “disregarded votes”, which were duly indicated in the detailed final voting map.

8.3.      Subsequently, after examination and discussion of the matter indicated in the Agenda, the shareholder Federal Government confirmed the election of Mr. Denilvo Morais, Brazilian, economist, divorced, holder of Identity Card RG No. 11.566.242-X, issued by SSP/SP, registered with the National Register of Individuals (CPF) under No. 896.703.618-34, resident and domiciled in the city of São Paulo, State of São Paulo, at Rua Sargento Silvio Nunes Miranda, No. 7, ZIP Code 02532-050, for the position of effective member of the Company’s Fiscal Council.

8.4.      It was also recorded that the member of the Fiscal Council now elected will take office in his respective position by signing the term of office, within the legal period of thirty (30) days, which will be recorded in the book of Fiscal Council Meetings and will be filed at the Company’s headquarters.

9.          VOTING MAP AND ADDITIONAL CLARIFICATIONS: The final voting map, containing the favorable vote regarding the only item on the Agenda of this Meeting, is contained in Schedule I to these minutes.

10.       CLOSURE: There being no further business to discuss, the Meeting was closed, from which these minutes were drawn up in summary form and published with omission of signatures, in accordance with article 130, § 1 and § 2, of the Brazilian Corporation Law, which was made available to all shareholders who requested a copy by e-mail and was signed by the members of the Board, with the shareholder Federal Government who participated in this Meeting through the Digital Platform made available by the Company having its presence recorded by the members of the Board and is a signatory of said minutes, pursuant to article 47, §1, of CVM Resolution 81.
