Welcome to our dedicated page for Energy Company of Minas Gerais SEC filings (Ticker: CIG), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
The SEC filings page for Companhia Energética de Minas Gerais – CEMIG (CIG) brings together the company’s U.S. regulatory reports as a foreign private issuer. CEMIG files an annual report on Form 20-F, which contains audited financial statements, segment information for electricity generation, transmission, trading, distribution, gas and equity interests, and detailed notes on its operations as a state-controlled mixed capital company in Brazil. These 20-F reports are central references for understanding the group’s consolidated net revenue, costs, EBITDA, profit, investments, debt and risk disclosures.
In addition to the annual 20-F, CEMIG submits Form 6-K current reports that furnish interim financial information and a broad range of corporate communications originally released in Brazil. These 6-Ks include earnings releases, quarterly and interim financial information, material facts, notices to the market and notices to shareholders. Through these filings, investors can access information on topics such as concession extensions for hydroelectric plants, auctions of Generation Scaling Factor credits, legal proceedings involving auctions of small-scale power plants, supplementary pension plan disputes, and the delisting of preferred shares from the Latibex segment of the Madrid Stock Exchange.
CEMIG’s 6-K exhibits also cover shareholder and capital events, including declarations of interest on equity and dividends, payout schedules, and call notices for ordinary and extraordinary shareholders’ meetings. These documents outline procedures for remote voting, digital participation and representation, reflecting the governance framework of a publicly held Brazilian utility with shares traded on São Paulo and New York exchanges.
On Stock Titan, CIG’s filings are updated as they are released through EDGAR, and AI-powered summaries help explain the structure and content of long documents such as the 20-F and multi-item 6-Ks. This allows users to quickly identify key information on CEMIG’s segment performance, regulatory developments, legal matters and shareholder decisions without having to read every page of the original filings.
Cemig reported a strong 4Q25, driven by non-recurring gains and solid operations. Consolidated IFRS net profit reached R$1,875.9 million versus R$997.6 million a year earlier, while adjusted profit was R$1,022.7 million, 12.3% lower. EBITDA rose to R$2,946.5 million, up 53.9%, but adjusted EBITDA slipped 6.5% to R$1,810.8 million, reflecting normalization of one-off effects.
The company is returning substantial cash to shareholders. It declared interest on equity of R$677.4 million (R$0.2368 per share) and dividends of R$417.3 million (R$0.1459 per share), and detailed a second 2024 payout installment totaling R$1,866.7 million to be fully paid by December 30, 2025.
Cemig is also reshaping its asset base. It concluded a corporate reorganization of 11 distributed-generation solar plants, completed the acquisition of transmission company ETTM for R$30.0 million, and exercised preemptive rights to acquire 51% of Hidrelétrica Pipoca for R$36.33 million, moving to full ownership of that 20 MW hydro asset subject to regulatory approvals. In 2025 it invested R$6.63 billion, mainly in distribution networks, smart meters and pipelines, while consolidated net debt increased 69.9% to R$16.8 billion and average debt maturity extended to 6.9 years.
The filing highlights resilient regulated operations: 4Q25 net revenue grew 2.9% to R$11.5 billion, Cemig D’s adjusted EBITDA edged up 1.7%, electricity losses and outage indicators remained within regulatory limits, and the 2025 tariff adjustment lifted average consumer tariffs by 7.78%. Gasmig’s 4Q25 net profit rose 24.1% despite lower gas volumes, aided by higher interest-on-equity distribution. Cemig also underscores multiple ESG recognitions, including CDP’s “A List”, inclusion in the S&P Global Sustainability Yearbook 2026, selection as one of Corporate Knights’ 10 most sustainable corporations in Latin America, and ranking 63rd in the Clean200 2026.
