To Mr. Leonardo George de Magalhães

Chief Investor Relations Officer.

Subject: Request for information on news media report

Dear Director,

We refer to the news report of June 7, 2021 in the Forbes Radar section of Forbes Brasil, which contains the following statements:

“Cemig is evaluating possible acquisitions of solar energy farms in the State, to expand its participation in the distributed generation market from the present 10% to 30% by the end of 2025, and for this it will receive, over five years, a total of R$ 1 billion in funds from Companhia Energética de Minas Gerais to invest in expansion.”

In view of the above, we require you to state whether the news report is true, and, if so, explain why you believed that this was not a material event, and comment on any other information considered to be important on the subject.

We highlight that, under Article 3 of CVM Instruction 358/02 it is the responsibility of the Chief Investor Relations Officer to disclose to and advise the CVM, and as the case may be, the stock exchange and/or any organized over-the-counter market on which securities issued by the company are traded, of any material event or fact which takes place or is related to its business, and to make best efforts for its immediate and wide dissemination, simultaneously to all the markets in which such securities are traded.

We further highlight that the practice of disclosing your expectations of future performance to the market (guidance), for both the short and the long term, especially in relation to the financial and operational aspects of your business, involves preparation of quantitative projections.

In relation to this, in compliance with §1 of Article 20 of CVM Instruction 480/09, we require that, if the statements are true, Item 11 of the issuer’s Reference Form must be updated to include the information required in sub-clauses ‘a’ to ‘d’.

Table of Contents

	He is a member of the Technical Committee of AMEC, with substantial knowledge of corporate governance, and experience on boards of directors and audit boards. He contributed to the IBGC and to AMEC in the construction of the Brazilian Code of Corporate Governance (CBGC). As from the launch of the CBGC he has inserted it as a working instrument in all the companies in which he works, in particular the ‘Apply or Explain’ model, a system that recognizes that corporate governance is a ‘journey’, and should not be translated into a rigid model of rules equally applicable to all companies. He has worked in companies in: electricity generation, transmission and distribution; distribution of natural gas; mining; steel and steel manufacturing; ports; basic industries; construction; construction materials and finishings; vehicle distribution and holding companies – acquiring knowledge in industry, trade, retailing and services that enable him to make constructive contributions in a very wide range of subjects and strategies that are dealt with in the boards in which he participates – such as: turnarounds, capital structure, mergers & acquisitions, sale of non-core assets, financial restructuring of companies in crisis, executive succession, etc. He has taken part in the deep process of raising awareness of the importance of independent members elected by minority stockholders in the last seven years. In his opinion, the failings in corporate governance that prevailed in state companies, added to the problems of corruption that spread in Petrobras and Eletrobras, among other companies, had an adverse effect on the Brazilian capital market, created an obligation to rethink the present rules of governance and create much more rigid rules and much more severe punishments.

Inquiry by B3

Cia. Energética de Minas Gerais – CEMIG

To Mr. Leonardo George de Magalhães

Chief Investor Relations Officer

Subject: Request for information on news media report

Dear Sirs,

A report in Valor Econômico newspaper of June 17, 2021, under the headline “CPI on Cemig”, states, among other information, that the Legislative Assembly of Minas Gerais has approved an application to open a Parliamentary Committee of Inquiry (CPI) to investigate supposed irregularities in the management of Cemig since 2019.

We request information/explanations on the item indicated, by June 18, 2021, including your confirmation of it or otherwise, and also any other information that is considered to be important.

Reply by CEMIG

Dear Ms. Ana Lucia da Costa Pereira,

In response to Official Letter 878/2021-SLS of June 17, 2021, Companhia Energética de Minas Gerais – CEMIG (‘Cemig’) reports that proceedings are indeed in progress in the Legislative Assembly of Minas Gerais for establishment of the said CPI, which is at the stage of appointment of members.

For this reason, Cemig believes that there is so far no information which, in the light of CVM Instruction 358/2002, would justify disclosure of a Market Notice or Material Announcement on this subject.

Cemig notes that its management decisions are based on best corporate governance practices and compliance.

Further, all procedures adopted by the present management aim not only to preserve the equity value and property of Cemig, but also to ensure supply of electricity services with quality and safety to its clients.

Cemig takes this opportunity to reiterate its commitment to transparency and best market practices in communication with the market.

MATERIAL ANNOUNCEMENT

New 5-year tariff review proposed for Gasmig

In compliance with CVM Instruction 358 of January 3, 2002 as amended, Cemig (Companhia Energética de Minas Gerais – listed in São Paulo, New York and Madrid) hereby reports to the Brazilian Securities Commission (CVM), the São Paulo Stock Exchange (B3) and the market in general:

Today Cemig’s subsidiary, Companhia de Gás de Minas Gerais – Gasmig published the following Material Announcement:

“

In compliance with CVM Instruction 358 of January 3, 2002 as amended, Gasmig (Companhia de Gás de Minas Gerais, listed on the São Paulo Stock Exchange – B3), hereby reports to the Brazilian Securities Commission (CVM), to B3 and to the market as follows:

On June 17, 2021 the Economic Development Department of the State of Minas Gerais (‘SEDE’), the State’s body responsible for regulation and ratification of tariffs for piped gas distribution service, published a notice in the Minas Gerais State Official Gazette that it will hold an electronic auction for provision of specialized services of regulation consultancy, for application of the methodology and the other procedures for review of tariffs for piped natural gas distribution service.

In the reference announcement for the electronic auction, SEDE gives the following grounds:

“It is the understanding of the Minas Gerais State Government that the events of 2019 and 2020, especially the effects of the Covid-19 pandemic and the collapse of the dam of Vale S.A. at Brumadinho, Minas Gerais, are characterized as totally unpredictable factors in relation to the scenarios that were the grounds for the studies made prior to the most recent Periodic Tariff Review (RTP), for the 2018-2022 period. These conditions led to increase of tariffs and reduction of consumption, with impacts both on consumers and on the concession holder.

Due to the negative impacts suffered, it is understood that bringing forward a new tariff review process will favor the economic and financial equilibrium of the concession, and also make possible repositioning of tariffs of the concession holder with a view to moderating their levels.

It is thus proposed to terminate the present tariff cycle early, on December 31, 2021, and begin a new five-year cycle on January 1, 2022.”

Gasmig will keep the market informed on this subject, in accordance with the applicable regulations.”

	He has worked in companies in: electricity generation, transmission and distribution; distribution of natural gas; mining; steel and steel manufacturing; ports; basic industries; construction; construction materials and finishings; vehicle distribution and holding companies – acquiring knowledge in industry, trade, retailing and services that enable him to make constructive contributions in a very wide range of subjects and strategies that are dealt with in the boards in which he participates – such as: turnarounds, capital structure, mergers & acquisitions, sale of non-core assets, financial restructuring of companies in crisis, executive succession, etc. He has taken part in the deep process of raising awareness of the importance of independent members elected by minority stockholders in the last seven years. In his opinion, the failings in corporate governance that prevailed in state companies, added to the problems of corruption that spread in Petrobras and Eletrobras, among other companies, had an adverse effect on the Brazilian capital market, created an obligation to rethink the present rules of governance and create much more rigid rules and much more severe punishments.

MATERIAL ANNOUNCEMENT

Request for information on Taesa disinvestment proposal

As per CVM Instruction 358 of January 3, 2002 as amended, Cemig (Companhia Energética de Minas Gerais, listed in São Paulo, New York and Madrid), hereby reports to the Brazilian Securities Commission (CVM), the São Paulo Stock Exchange (B3) and the market as follows:

On July 7, Cemig received notification from the State Audit Board (Tribunal de Contas do Estado) of the State of Minas Gerais (‘TCE-MG’) to present all the documentation relating to the process of disposal of Cemig’s equity interest in Taesa.

Certain members of Minas Gerais State Legislature had presented a demand to the TCE-MG, to:

“

... suspend all and any acts of disinvestment by Cemig in Taesa, until prior technical studies have been carried out which demonstrate that an auction sale of these shares is advantageous, and what conditions must be met to ensure that it would be advantageous (...)”

– on the allegation, by the requesting members, that technical studies to justify the transaction have not been carried out.

The TCE-MG did not grant the members’ request to suspend the process of sale, but recommends that Cemig should abstain from any action relating to the sale of the shares in Taesa until the Technical Unit of the TCE-MG is able to analyze all of the documentation requested.

Cemig emphasizes that the competitive process for the sale that is under study obeys all the rules of law, regulations, and the São Paulo Stock exchange (B3) for execution of the related specialized auction; and that the process of disposal is taking place with the advisory services of a specialized financial institution, based at all times on best governance practices for transactions of this type.

Cemig will keep the market and other interested parties informed on this subject, in accordance with the applicable regulations.
