Re: Request for clarification on a news article published in the press

Dear Sirs,

The news article published by the Valor Econômico newspaper on October 18, 2023, entitled "Cemig's privatization model predicts that the company will not have a definite control," states, among others, that the proposal of the Minas Gerais State Government:

1. consists of converting all Cemig shares into common shares;
2. includes the creation of the "golden share," which gives the State veto power over certain decisions and ensures that no shareholder will have more voting rights than the State.

We hereby request for clarification on the aforementioned items by October 19, 2023, with your confirmation or refutation, as well as other information considered to be important.

Dear Ms. Ana Lucia da Costa Pereira,

In response to Official Letter 1.207/2023 - SLS, dated October 18, 2023, Companhia Energética de Minas Gerais - CEMIG ("Cemig" or "Company") clarifies that:

The news article published by the Valor Econômico newspaper on October 18, 2023, entitled "Cemig's privatization model predicts that the company will not have a definite control," was an assessment, according to the newspaper itself, presented by Governor Romeu Zema to state congresspeople of his support base.

It is worth noting the context of the news article that involves the interest of the Minas Gerais State Government, which represents the Company's controlling shareholder, in line with the Notice to the Market already published on August 21, 2023.

It consists of an exclusive process under the authority of the controlling shareholder and other external agents, according to legislation of the State of Minas Gerais.
