Nomination of Candidates to the Fiscal Council

Rio de Janeiro, April 6, 2026, Centrais Elétricas Brasileiras S.A. - Eletrobras (the "Company" or “AXIA Energia”), in continuation of the notice to shareholders dated March 13, 2026, hereby informs that the candidates nominated for membership on the Fiscal Council, listed below, have been reviewed and approved by the Company as to compliance with the eligibility requirements set forth in Brazilian Law No. 6,404/76, the Bylaws, and AXIA Energia's Policy on Nomination and Succession of Officers and Directors.

With respect to the candidate Mr. José Reinaldo Magalhães (effective member), nominated jointly by Banco Clássico and Radar, the Company informs that he currently holds a position as a member of the board of directors of CEMIG – Companhia Energética de Minas Gerais S.A. and TAESA - Transmissora Aliança de Energia Elétrica S.A., competing companies of the Company, with terms in office through their respective annual general meetings in 2026. Additionally, Mr. José Reinaldo Magalhães is a candidate for reelection to the board of directors of TAESA for a new one-year term.

Accordingly, pursuant to Article 28, Paragraph 3, item I, in conjunction with Article 49, Paragraph 5, both of the Bylaws, and further in compliance with Article 147, Paragraph 3, Item I, in conjunction with Article 162, Paragraph 2, of Brazilian Law No. 6,404/76, the Company informs that the eligibility of said candidate is contingent upon the granting, by the shareholders' meeting, of a waiver of the requirements set forth in Article 147, Paragraph 3, of Brazilian Law No. 6,404/76.

The shareholders responsible for the nomination justified it, noting that he is an experienced professional in the sector, with an unblemished reputation and recognized technical expertise. They further highlighted that, in their view, TAESA operates predominantly in the regulated electric power transmission segment, so that potential conflicts of interest would be manageable, and the nominee should adopt a posture before AXIA Energia's Fiscal Council of not accessing any information and not participating in any debate or decision involving the electric power transmission segment, for as long as the factual situation described above persists.
