Copel Agreement

Rio de Janeiro, December 12, 2024, Centrais Elétricas Brasileiras S.A. – Eletrobras and the Companhia de Geração e Transmissão de Energia Elétrica do Sul do Brasil - CGT Eletrosul inform that, on this date, they concluded the signing of an agreement with Copel Geração e Transmissão and Companhia Paranaense de Energia – Copel to carry out a swap of assets/participations where:

Colíder HPP, with a capacity of 300 MW, is located in Mato Grosso, on the Teles Pires River, where the Company already holds control of Teles Pires HPP (1,820 MW), in addition to stakes in Sinop HPP (402 MW) and São Manoel HPP (700 MW), with potential value generation through operational synergies. The plant has contracts in the Regulated Contracting Environment (ACR) for approximately 70% of its Physical Guarantee, with a term until 2044, and contracts in the Free Contracting Environment (ACL) for the remaining Physical Guarantee, with terms until 2029.

The assets of Colíder HPP will be received without cash, with a debt of approximately R$408 million and an estimated EBITDA of around R$235 million in 2025.

As a result of the transaction, Eletrobras will increase its installed generation capacity by 122 MW, with an increase in EBITDA and Net Income upon closing and a reduction in net debt¹.

The transaction, whose conclusion is subject to usual market conditions and adjustments, reinforces Eletrobras' commitment to optimizing minority interests with value generation, following capital discipline, and simplifying its structure as provided for in its Strategic Plan.

Note: (1) Estimated reduction in net debt of R$19.5 million in 2025
