Cemig’s 3Q25 results show lower earnings after exceptional gains in 2024, alongside major strategic and labor developments. Net revenue rose 4.6% year-on-year to R$10.62 billion, driven mainly by higher electricity and TUSD distribution revenues, while consolidated net profit fell to R$796.7 million from R$3.28 billion due to large one-off gains in 3Q24 from a transmission tariff review and the sale of Aliança. Adjusted Ebitda was R$1.47 billion, 16.3% below 3Q24, reflecting higher energy purchase costs, greater use of outsourced services, higher provisions and weaker gas volumes, partly offset by tariff increases and higher electricity sales.
Cemig approved a new 2026–2030 strategic plan with an estimated R$44 billion investment program, including about R$6.7 billion planned for 2026 focused on distribution, transmission, generation, distributed solar and gas. The company also concluded a single collective bargaining agreement on retiree health plans, capping compensatory buyouts at up to R$1.28 billion over six installments through 2030 and ending Cemig’s sponsorship of the PSI plan from December 31, 2025. Debt increased, with consolidated gross debt at R$15.41 billion in September 2025 and Cemig GT issuing R$1.5 billion in debentures rated ‘AAA.br’. Cemig advanced its energy-transition and ESG agenda, maintained power-quality indicators within regulatory limits, and modestly expanded distributed solar through a 10 MWp acquisition by Cemig SIM.
Companhia Energética de Minas Gerais (Cemig) filed a Form 6-K reporting Q2 2025 results and corporate actions. Net revenue reached R$10.786 billion, up 14.3% year over year.

The shift reflects higher electricity purchase costs, construction activity, and a swing to net financial expense of R$263 million.
Operations and regulation: Distribution adjusted EBITDA rose 39.2%, supported by tariff components and higher TUSD revenue, while transmission included a RBSE remeasurement effect of R$198.895 million. Aneel ratified Cemig D’s annual tariff adjustment effective May 28, 2025, with an average increase of 7.78%.
