His Excellency Min. Nunes Marques Rapporteur of Direct Action of Unconstitutionality No. 7385 The Attorney General of the Federal Government, in the exercise of his constitutional and legal prerogatives (articles 103, paragraph 3, and 131 of the Constitution, as well as article 4, item III, of Complementary Law No. 73/1993), and CENTRAIS ELÉTRICAS BRASILEIRAS S/A - ELETROBRAS, respectfully come to report and, in the end, request the following. 1. According to Your Excellency's decision, issued on September 18, 2024, in the proceedings of this Direct Action of Unconstitutionality No. 7,385/DF (electronic document No. 250), it was determined that conciliatory negotiations continue within the scope of the Federal Public Administration Mediation and Conciliation Chamber (CCAF) of the Attorney General's Office, as well as monitoring of the progress of the negotiations through proof of adjustments and stages covered. 2. In this sense, specific proof was determined: (i) of the commitment to resolving the issues articulated in this action; (ii) of the stages covered indicating the progress of the negotiations; and (iii) of the adjustments, even if partial, signed. 3. In compliance with the determinations of this Federal Supreme Court, several meetings were held between the Federal Governemnt represented by several sectoral bodies of the Federal and Indirect Public Administration, and Centrais Elétricas Brasileiras S/A - Eletrobras, with the purpose of achieving proactive and effective results for the consensual resolution of the controversy. 4. The various meetings held allowed the proposed adjustments to evolve in a consensual manner, as can be seen, including, from the relevant facts and communications published on the respective websites, which demonstrate a genuine engagement of the parties in favor of resolving the issues articulated in this direct action. 5. This negotiation dynamic aims to guarantee a legally secure, conclusive solution that meets the best principles of law and public interest. 6. With the evolution of the proposals at the negotiating table, the parties moved towards an understanding, already disclosed in a relevant fact by Eletrobras and reported on the AGU website, regarding the following points: • Full preservation of the provisions contained in art. 3, III, items "a" and "b", of Law No. 14,182, of July 12, 2021, and of arts. 6, 7 and 8 of the Company's Bylaws. • Establishment of vacancies for the Federal Government on the Company's Board of Directors and Fiscal Council. • Coordination of a possible divestment process by Eletrobras of its shareholding in Eletronuclear S.A. through the search for a new shareholder. • Definition of terms that may allow the review of the Investment Agreement entered into between the Company and Empresa Brasileira de

Participações em Energia Nuclear e Binacional S.A. - ENBPar, related to the Angra 3 Nuclear Power Plant project, considering the Company's interest in being released from the Agreement. • Maintenance of guarantees provided for financing contracted in favor of Eletronuclear S.A. prior to the privatization of the Company. 7. Once the last outstanding points have been defined, the parties will make their best efforts to draft the conciliation agreement, the effectiveness of which will depend on: (i) legal and regulatory authorizations by the Federal Government; (ii) approval of its terms by the Extraordinary General Meeting of Eletrobras shareholders, at which the Federal Government and shareholders linked to it will abstain from voting; and (iii) approval by the Supreme Federal Court. It is worth highlighting, as a demonstration of the parties' efforts to conclude the conciliation process in the coming days, that the aforementioned Extraordinary General Meeting, required to deliberate on the approval of the conciliation agreement by February 2025, must be called at least 30 days in advance, in order to comply with the legal deadlines and the complexity and relevance of the matter to be deliberated. 8. Considering the conclusive stage of the negotiations and the need to meet the deadlines required to comply with these suspensive conditions before the Eletrobras Ordinary General Meeting that will elect the new composition of its board of directors and fiscal councils, which must be convened in March 2025 and take place by the end of next April, it is necessary for the parties to file the conciliation term with the Supreme Federal Court, duly approved by its governance bodies, as explained above, still during the month of February 2025. For this reason, the parties, jointly, request an extension for another sixty days of the suspension of the processing of this direct action. Terms under which they await approval Brasilia, December 17, 2024 JORGE RODRIGO ARAÚJO MESSIAS Attorney General of the Federal Government ISADORA MARIA BELEM ROCHA CARTAXO DE ARRUDA General Secretary of Litigation Pela Eletrobras LUIS INÁCIO LUCENA ADAMS
