Material Changes and Operational Highlights
- Profitability Decline: The sharp drop in IFRS profit and EBITDA is primarily due to the absence of one-time gains in 3Q24. Adjusted metrics show a more moderate decline of 16.3% in EBITDA and 30.2% in net profit.
- Cost Pressures: Net finance expenses increased by R$214.5 million (348.6% YoY) due to higher gross debt and the Selic rate rising to 15.00%. Energy purchase costs rose 13.0% due to higher spot prices and a lower Generation Scaling Factor (GSF).
- Distribution Volume: Total energy distributed by Cemig D fell 4.4% YoY, driven by an 8.0% drop in industrial consumption due to client migration to the Free Market and Distributed Generation (DG).
- Gas Segment: Gasmig EBITDA fell 8.2% as captive market sales dropped 54.5%, though Free Market sales surged 196.6%.
- Investments: Capex for 9M25 totaled R$4.73 billion (+17.0% YoY). The company announced a R$44 billion investment plan for 2026-2030, with R$6.7 billion allocated for 2026.
Guidance, Outlook, and Risks
- Strategic Plan: The Board approved a 2026-2030 plan focusing on grid modernization, renewable expansion, and energy transition. 2026 investment is estimated at R$6.7 billion.
- Health Plan Resolution: CEMIG finalized a collective bargaining agreement regarding retiree health plans. The company will pay a maximum of R$1.28 billion in six installments (ending 2030) to buy out its obligations, terminating sponsorship of the PSI plan by December 31, 2025.
- Legal Contingencies:
- Consumer Refunds: The Federal Supreme Court ruled on the constitutionality of tax refund laws (ADI 7,324); CEMIG is assessing financial impacts.
- Asset Divestment: A court injunction temporarily suspending the auction of four small power plants was lifted on December 8, 2025, allowing the divestment process to continue.
- Rating Upgrade: Moody's upgraded CEMIG's rating to AAA.br in September 2025.
Key Facts for Investor Verification

- Health Plan Liability: Confirm the cash flow impact of the R$1.28 billion buyout payment schedule for retiree health plans through 2030.
- Regulatory Risks: Monitor the final accounting impact of the Supreme Court ruling on consumer tax refunds (ADI 7,324).
- Industrial Migration: Assess the long-term revenue impact of continued industrial client migration to the Free Market and Distributed Generation.
- Investment Execution: Track the execution of the R$44 billion 2026-2030 investment plan, particularly the R$6.7 billion allocated for 2026.
