The Fiscal Council of AXIA Energia ("Company"), in the exercise of the powers granted to it under the Article 166, paragraph 2, of the Brazilian Law No. 6,404, of December 15, 1976 ("Brazilian Corporate Law"), examined the proposal of the Company’s Management to increase the Company’s capital stock, within the limit of the authorized capital, pursuant to the caput of Article 5 of the Bylaws, through the capitalization of a portion of the balances recorded in the Company’s Profit Reserves accounts, in the amount of R$30,000,000,024.48 (thirty billion, twenty-four reais and forty-eight centavos) ("Capitalization"), with the consequent issuance and delivery to the Company's shareholders of 606,796,117 (six hundred and six million, seven hundred and ninety-six thousand, one hundred and seventeen) preferred shares, designated as class ‘C’, registered, book-entry and without par value, convertible into common shares and redeemable ("PNC"), as a bonus issue, pursuant to article 169 of the Brazilian Corporate Law ("Bonus Issue"). It was hereby stated that the effectiveness of the Capitalization and Bonus Issue is subject to the full approval of the matters included in the Agenda of the Extraordinary General Meeting to be held on December 19, 2025 ("EGM").

Accordingly, the Fiscal Council, by unanimous vote of the members present, expresses a favorable opinion on the Company’s proposed Capitalization, as formulated by the Executive Board and already approved by the Board of Directors, the effectiveness of which is subject to the full approval of the matters included in the agenda of the EGM.
