MATERIAL FACT

AES BRASIL ENERGIA S.A ("Company") (B3: AESB3), in compliance with the provisions set forth in paragraph 4 of article 157 of Law 6,404, of December 15, 1976, as amended, and the Brazilian Securities and Exchange Commission (Comissão de Valores Mobiliários or "CVM") Resolution 44, of August 23rd, 2021, informs its shareholders and the overall market that the Company's management is studying the possibility of carrying out a potential public offering for distribution with restricted efforts to place shares issued by it in accordance with CVM Instruction 476, of January 16, 2009, as amended ("Potential Offering"). To this end, the Company informs that it has started an engagement process with certain financial institutions, as well as certain international affiliates of these institutions, to determine the feasibility of the Potential Offering, together with the Company.

The Company has a broad track record with the operation of renewable power generation assets and owns an asset portfolio with a total installed capacity of 4.4 GW, consisting of 2,658.4 MW originated from hydroelectric energy sources, 1,435.9 MW originated from wind energy sources and 294.1 MW originated from solar energy sources. In addition, the Company continues to develop part of its wind and solar assets pipeline, which projects remain subject to ongoing negotiations and may add up to 1.5 GW of installed capacity.

Based on a strategy focused on portfolio growth and diversification by means of developing energy sources that are complementary to its hydroelectric assets, including via long-term agreements and consistent returns, the Company believes that its growth plan may be accelerated by the Potential Offering and, as a result, create value for its shareholders.

The Company has not yet defined or approved the effective realization of the Potential Offering or its terms and conditions and, therefore, on this date, no public offering for the distribution of shares issued by the Company in Brazil, in the United States of America or any other jurisdiction is being carried out.

The effective realization of the Potential Offering is subject, among other factors, to obtaining the necessary approvals, including applicable corporate approvals, to favorable political, macroeconomic and market conditions, to the interest of investors in participating, to the execution of definitive agreements, to procedures inherent to the execution of public offers in the form of the current regulation, among other factors beyond the control of the Company. If effective, the Potential Offering will be conducted in accordance with the applicable laws and regulations.

This Material Fact is for information purposes only and should not, under any circumstances, be interpreted as, nor constitute, an announcement of a public offering of any securities issued by the Company in Brazil, the United States of America or any other jurisdiction, or an investment recommendation.

It is noteworthy that this Material Fact is not intended to be published, directly or indirectly, in the United States of America or any other jurisdiction. The securities mentioned in this Material Fact that may be distributed in the event of the Potential Offering being made will not be registered under the United States Securities Act of 1933 ("Securities Act") or any other securities law, and shall not be offered, sold, pledged or otherwise transferred in the United States of America without proper registration or an exemption from registration applicable under the Securities Act.

The Company will keep its shareholders and the overall market duly informed about any developments or resolutions regarding the matter, respecting the restrictions contained in CVM rules and applicable legislation.
