Subject: Request for clarification on the news article

Dear Director,

1. In response to the news article published electronically by Folha de São Paulo in its market section on October 18, 2021, under the headline: "Zema wants to turn Cemig into a private company with no controlling shareholder", with the following statements:

The privatization model proposed by Governor Romeu Zema (Novo) for Cemig (Companhia Energética de Minas Gerais) will leave the company without a controlling shareholder. The idea is to turn the company into a corporation.

The state is expected to act as a reference shareholder with veto power over decisions if it uses the so-called golden share.

The plan was presented by Zema to the lawmakers of his base on Tuesday

1. during a cocktail event at the Palácio da Liberdade, the former government headquarters. The privatization needs to be approved by the State Legislature.

According to the government, preferred shares, which entitle the holder to dividends, will be converted into common shares. Thus, 100% of the company's shares will be common shares. These are the shares that give their holders the right to vote on corporate decisions.

Classification: Targeted

The state will retain 17.04% of the total Cemig shares, which gives it control over the state-owned company. However, with the conversion of shares and under the new management system, it will no longer be the main shareholder.

1. Because of the above, we request that you clarify whether the news article is true and, if so, explain why you believe it is not a material fact, and comment on other information deemed as important on the matter.
2. It is worth noting that according to article 3 of CVM Resolution 44/21, the Investor Relations Officer is responsible for disclosing and informing the CVM and, if applicable, the stock exchange and the organized over-the-counter market entity where the Company's securities are traded, any material act or fact occurred or related to its business, as well as ensure its wide and immediate communication, simultaneously in all the markets in which such securities are traded.
