CVM Questioning
Re: Clarifications about CVM/B3 questioning
Subject: News Article Published in the Media
Dear Director,
“1. We refer to the news report published on March 23, 2026, by CNN Brasil, in the News section, under the headline “CEO of Cemig defends corporation model for the Company,” which contains the following statements:
The CEO of Cemig (Companhia Energética de Minas Gerais), Reynaldo Passanezi, said in an interview with CNN Infra’s Alta Voltagem program that he views the corporation model as a way to unlock value and expand the Company’s growth capacity.
The proposal, defended by the Government of Minas Gerais and currently under review by ALMG (Legislative Assembly of Minas Gerais), provides for the transformation of the state-owned company into a widely held corporation, with no defined controlling shareholder.
In practice, the Company would migrate to B3’s Novo Mercado listing segment, and would thereafter have only common shares.
Under this structure, the State would cease to be the controlling shareholder, while retaining a significant interest, estimated at approximately 17% of the total capital, in addition to mechanisms such as a golden share, which would ensure veto power over strategic decisions.
2. In light of the above, we request that you clarify whether the news article is true and, if so, explain the reasons why you believe that it is not a material fact, and comment on other information deemed as important regarding the matter (...)”
CEMIG’s Clarification
Dear Sirs,
1. With reference to Official Letter 121/2026/CVM/SEP/GEA-1, sent by you and received on March 25, 2026, Companhia Energética de Minas Gerais – CEMIG (“Cemig” or “Company”) hereby respectfully submits to this Business Monitoring Management 1 of the Brazilian Securities and Exchange Commission (“CVM”) its response as follows.

2. Pursuant to said Official Letter, clarifications were requested regarding the news report published on March 23, 2026, by CNN Brasil, in the News section, under the headline “CEO of Cemig defends corporation model for the Company,” which contains the following statements:
The CEO of Cemig (Companhia Energética de Minas Gerais), Reynaldo Passanezi, said in an interview with CNN Infra’s Alta Voltagem program that he views the corporation model as a way to unlock value and expand the Company’s growth capacity.
The proposal, defended by the Government of Minas Gerais and currently under review by ALMG (Legislative Assembly of Minas Gerais), provides for the transformation of the state-owned company into a widely held corporation, with no defined controlling shareholder.
In practice, the Company would migrate to B3’s Novo Mercado listing segment, and would thereafter have only common shares.
Under this structure, the State would cease to be the controlling shareholder, while retaining a significant interest, estimated at approximately 17% of the total capital, in addition to mechanisms such as a golden share, which would ensure veto power over strategic decisions.
3. Specifically, clarification was requested regarding the truthfulness of the news report and, if confirmed, an explanation of the reasons why it was deemed not to constitute a material fact, as well as any other information considered important on the matter.
4. We hereby clarify that the news report released by the media was based on an interview given on March 23, 2026, to Alta Voltagem, a program aired on CNN Brasil, in which Cemig’s CEO was asked, among other matters, about the possible interest of the Government of the State of Minas Gerais in the privatization of the Company.
5. On that occasion, Reynaldo Passanezi Filho stated that the proposals for the Company’s privatization had been duly submitted by the controlling shareholder to the Legislative Assembly of Minas Gerais (ALMG), and that any discussions and resolutions on the matter fall within political spheres external to the Company. To this effect, see the following excerpt from the interview:
CNN Reporter – Reynaldo, one important point: the Government of Minas Gerais has signaled an interest in privatizing Cemig, after having also spoken about federalizing the Company. It has already been attempted under both administrations of Governor Romeu Zema, and the government has even faced resistance, including a CPI proceeding in which you were required to provide clarifications. Why, then, privatize an asset that has been undergoing this divestment process, has been delivering results, and that you consider to be so efficient?
CEO of CEMIG – (...). The corporation model is a matter under discussion by the controlling shareholder. It is therefore a matter under discussion between the Executive and Legislative

branches. The Executive has already submitted a proposal to the Legislative branch, and it is currently under review by the Legislative Assembly of Minas Gerais (ALMG). What is this model? And perhaps clarification is warranted here. It is not privatization in the sense of selling off public assets, but rather the transformation of the Company into a corporation. What is this? The State currently holds 51% of the voting capital, but only 17% of the total capital. Thus, the corporation proposal consists of the Company migrating to Novo Mercado and, therefore, having only common shares. In this case, if there were only common shares, the State would hold 17% of the capital. It would remain the reference shareholder, there would be no sale of any shares, the public assets would remain fully preserved, with a possibility of appreciation due to the greater ease of private-sector management. Therefore, this is a matter that the Legislative Assembly has to decide, and the Executive’s proposal is very clear (...).
(emphasis added)
6. As can be seen, the Company’s CEO provided additional clarifications on the corporate structure and operation of a Corporation — a potential model proposed by the controlling shareholder to ALMG — since the proposal mentioned by the reporter was already widely known prior to the interview.
7. It should be emphasized that CEMIG has acted diligently and in compliance with the applicable laws and regulations, timely disclosing to its investors and to the CVM any material information it receives and/or becomes aware of regarding the Company’s privatization proposals and any updates thereto, as exemplified by the Material Facts disclosed on November 14, 2024, August 01, 2025, and November 06, 2025.
8. Accordingly, the news report merely reflects information that had already been duly disclosed to the market by CEMIG. The statements made by its CEO contained in the aforementioned news report do not constitute any supervening act or fact capable of causing disruption to the Brazilian capital market, especially given the cautious and contextualized manner in which they were presented.
9. In view of the foregoing, Cemig understands that there was no irregularity in the absence of disclosure of a material fact as a result of the publication of the questioned news report, since its content does not trigger any of the events set forth in CVM Resolution 44/21 that would make such disclosure mandatory.
10. Finally, the Company, reiterating its commitment to corporate governance best practices, reaffirms its commitment to transparency and disclosure to its investors.
11. Cemig remains at your disposal for any further clarifications deemed pertinent.
Sincerely,
Belo Horizonte, March 26, 2026.

Dear Sirs,
In response to the Official Letter, CEMIG hereby respectfully informs the Corporate Issuer Supervision Office 1 of the Brazilian Securities and Exchange Commission (“CVM”) that the Company has fully implemented the requested adjustments, as follows:
(i) inclusion of the deadline for submission of the BVD

The Company recommends that any new submission be made through the same service provider previously used to avoid inconsistencies in voting instructions.
