Announcement of corporate demand

Rio de Janeiro, December 26, 2025 – Centrais Elétricas Brasileiras S/A – AXIA Energia, in compliance with Annex I of CVM Resolution No. 80, dated March 29, 2022, informs, as a supplement to the announcement of corporate demand disclosed on March 31, 2025, that a decision on lack of jurisdiction has been rendered in the following corporate demand:

| Name of parties involved in the process: | Plaintiffs: Associação dos Empregados
de Furnas – ASEF and Caixa de Assistência dos Empregados de Furnas e Eletronuclear – CAEFE (“Plaintiffs”). Defendants: Centrais Elétricas Brasileiras S/A – AXIA Energia (“Company”), Furnas Centrais Elétricas S/A
and the Federal Government. |
| --- | --- |
| Case No.: | 0150484-53.2022.8.19.0001 |
| Court: | 7th Corporate Court of the Rio de Janeiro State Court of Justice – TJRJ |
| Values, goods or rights involved: | The amount in dispute was set at R$ 1,000. |
| Demand date: | - June 4, 2022 – filing date before the 14th
Federal Court of the Federal District - December 9, 2025 – date on which the 7th
Corporate Court of TJRJ declared its lack of jurisdiction and returned the case to the 14th Federal Court of the Federal Distric |
| Main Facts: | This is a request for preliminary injunctive relief
in which the Plaintiffs challenge the contribution of R$ 1.583 billion made by Furnas—then a subsidiary of the Company—to
Madeira Energia S.A. – MESA, the sole shareholder of Santo Antônio Energia S.A. – SAESA, responsible for operating the
Santo Antônio Hydroelectric Plant in Rondônia The Plaintiffs argue that the contribution occurred
prior to the General Meeting of Debenture Holders of the 2nd Series of the 1st Issuance of Furnas Debentures, and that such allegedly
reckless act would generate negative consequences for Furnas’ corporate interests. The General Meeting of Debenture Holders, held on
June 6, 2022, approved the contribution made to MESA, without any harm to Furnas’ interests. |
| Court Decision: | On December 9, 2025, the 7th Corporate Court of TJRJ declared its absolute lack of jurisdiction and ordered the return of the case to the 14th Federal Court of the Federal District. Should the latter Court disagree, the case records must be returned to the 7th Corporate Court of TJRJ so that a conflict of jurisdiction may be raised. |
