Closing of the Divestment of Santa Cruz Thermal Power Plant – Sale of Thermal Assets

Rio de Janeiro, October 9, 2025, Centrais Elétricas Brasileiras S/A – Eletrobras informs that, in addition to the material facts disclosed on June 10, 2024, and May 14, 2025, and following the fulfillment of the agreed precedent conditions, the company has concluded, on this date, the divestment of its last thermal asset, Santa Cruz Thermal Power Plant (UTE Santa Cruz), to J&F S.A., the successor of Âmbar Energia under the agreement.

Eletrobras received the amount of R$ 703.5 million, which, added to the proceeds from the sale of Eletronorte’s thermal power plants, totaled R$ 3.6 billion, in addition to the cash generated by the plants between the signing of the agreement and their respective closings. The company also retains the right to receive the earn-out agreed between the parties, with a total base value of R$ 1.2 billion.

This transaction marks the completion of the divestment process of Eletrobras’ thermal power assets, and as of this date, the company’s generation portfolio is composed exclusively of 100% renewable energy sources, in line with its Net Zero 2030 commitment.

Eletrobras reaffirms its commitment to shareholders and the market to optimize its portfolio and capital allocation, with a focus on value creation and the simplification of its corporate structure, as outlined in its Strategic Plan.
