Consolidation of the Três Irmãos HPP Rio de Janeiro, October 29, 2025, AXIA Energia announces that, on the previous day, it has entered into a Share Purchase Agreement with Triunfo Participações e Investimentos S.A. (TPI) and Mercúrio Participações e Investimentos S.A. (Mercúrio) for the acquisition of 100% of the shares of Juno Participações e Investimentos S.A. (Juno), the controlling shareholder (50.1%) of Tijoá Energia, for a total ammount of R$247 million, in a single installment on the transaction closing date. Tijoá Energia, in which AXIA Energia already held a 49.9% equity interest, is the concessionaire responsible for the Três Irmãos Hydroelectric Plant (UHE Três Irmãos), located in the municipality of Andradina, São Paulo, on the Tietê River, with an installed capacity of 808 MW. With this agreement, AXIA Energia will consolidate 100% ownership of the plant, which operates under the quota system (sistema de cotas). In 2024, the plant recorded annual revenue of R$320 million and EBITDA of R$136 million, with no outstanding debt and a concession term extending until 2044. The hydroelectric facility also has existing infrastructure prepared for the installation of three additional generating units, allowing for a potential future expansion of its capacity. The transaction is the result of an agreement entered into between AXIA Energia and the controlling shareholders of Juno, and brings to an end the arbitral and judicial disputes between the parties, related to the control of the plant, which date back to 2021, allowing the Company, in addition to assuming control of the hydroelectric plant, to release approximately R$390 million in court deposits related to the proceedings. The transaction is aligned with AXIA Energia’s Strategic Plan, reinforcing its commitment to portfolio optimization and capital allocation, with a focus on value creation, risk mitigation, and the simplification of its structure. The completion of the transaction is subject to the usual market conditions. Eduardo Haiama Vice President of Finance and Investor Relations
