CEMIG (“CEMIG” or “Company”), a publicly held company with shares traded on the stock exchanges of São

(“B3”) and the market in general that, further to the material fact disclosed by the Company on November 12, 2021,
Cemig GT concluded, on May 5, 2022, the sale of all its equity interest held in the share capital of Renova Energia S.A. – Under
Court-supervised Reorganization (“Renova”), and the onerous assignment of all its credits held in Renova Comercializadora

electricity generation, transmission and distribution in the state of Minas Gerais, as was publicly disclosed.
Cemig and Cemig GT reaffirm their commitment to keeping
shareholders, the market in general and other stakeholders duly and timely informed about this topic, pursuant to the applicable regulation,
