CENTRAIS ELÉTRICAS BRASILEIRAS S/A

CNPJ: 00.001.180/0001-26 | NIRE: 533.0000085-9

PUBLIC COMPANY

Centrais Elétricas Brasileiras S/A ("Company" or "Eletrobras") (B3: ELET3, ELET5 & ELET6; NYSE:

EBR & EBR.B; LATIBEX: XELT.O & XELT.B) in compliance with CVM Instruction 358 and paragraph 4, of article 157, of Law 6,404/76, and respective amendments, hereby informs its shareholders and the market in general, the approval, on this date, by the National Electric Energy Agency ( "ANEEL"), from the re- profiling of the financial component of RBSE ("Basic Network Existing System").

The flow was established by Homologatory Resolutions No. 2,710 / 2020, 2,713 / 2020, 2,716 / 2020 and 2,717 / 2020, related to the periodic review of the Annual Allowed Revenues - RAPs associated with the transmission facilities under the responsibility, respectively, of Furnas Centrais Elétricas SA - Furnas, Centrais Elétricas do Norte do Brasil SA - Eletronorte, South Brazil Electricity Generation and Transmission Company - Eletrobras CGT Eletrosul and Companhia Hidro Elétrica do São Francisco - CHESF. The Agency's decision to reprofile the financial component of RBSE foresees a reduction in the payment curve of these amounts for the 2021/2022 and 2022/2023 cycles and an increase in the payment flow in the cycles after 2023, extending such installments until the 2027 / 2028, preserving, however, the remuneration for the WACC.

As is well known, the discussion regarding RBSE has been going on since 2017, when, having recognized its inclusion in the Regulatory Remuneration Base of the broadcasters and its updating criteria by Ordinance MME No. 120/2016, legal measures were proposed by consumers, who obtained decisions suspending the payment of the portion of the unincorporated cost of capital from the extension of the concessions to the tariff process (ke).

The payment of this installment only returned to the RAPs in 2020, with the decommissioning of the judicial decisions, without, however, having recognized the remuneration of the unpaid amounts from 2017 to 2020. However, the same decision by ANEEL that promoted the re-profiling of the component financial, recognized the right of the transmission companies to remunerate the amounts whose payment was suspended in court, adding the amounts to the respective RAPs, also as a financial component of RBSE, thus complying with reconsideration requests that had been submitted in view of the aforementioned Homologating Resolutions.

Aneel's decision in reference brings the following estimated effects to the payment flow of Eletrobras'
