ENERGY CO OF MINAS GERAIS

We have adopted a code of ethics as defined in Item 16B of Form 20-F under the Exchange Act. Our code of ethics applies to our Chief Executive Officer, Chief Finance, and Investor Relations Officer, and to persons performing similar functions, members of the Board of Directors, other officers, and employees. In 2022, the document was completely revised, having undergone a change in its name, format, and content, with the purpose of giving greater clarity to all involved about the ethical principles and rules of conduct of the Company. Also, all employees must mandatorily receive the training on CEMIG’s Code of Conduct, every year.

Our code of ethics is filed with the SEC as an exhibit to this Form 20-F and is available on our website www.cemig.com.br. If we change the provisions of our code of ethics that apply to our Chief Executive Officer, Chief Finance, and Investor Relations Officer, and/or persons performing similar functions, or if we grant any waiver of such provisions, we will disclose such change on our website at the same address.
