Companhia Energética de Minas Gerais – CEMIG (NYSE: CIG) is a publicly held Brazilian utilities company that operates in the electric energy and gas sectors. According to its regulatory disclosures, the company is domiciled in Brazil and is controlled by the State of Minas Gerais. CEMIG has shares traded on the stock exchanges of São Paulo and New York, and its preferred shares have also been listed on the Madrid stock exchange’s Latibex segment, from which the company has approved a delisting process. The company’s activities cover the construction, operation and commercialization of systems for the generation, transmission, distribution and sale of energy, as well as activities in various fields of the energy sector and gas distribution, either directly or through subsidiaries and other investees.

CEMIG operates through distinct business segments that reflect its role in the Brazilian energy market. In its filings, it presents results for electricity generation, transmission, trading, distribution, gas and equity interests. These segments are consolidated in its financial reporting and are supported by wholly owned subsidiaries, including CEMIG Geração e Transmissão S.A. (CEMIG GT) and Gasmig. The company’s consolidated electricity market includes millions of clients across residential, industrial, commercial, rural and public service categories, as well as other agents in the Brazilian electricity sector.

Business model and segments

CEMIG’s business model, as described in its official documents, is centered on integrated participation in the energy value chain. The company reports net revenue and costs by segment for electricity generation, transmission, trading and distribution, as well as for gas and equity interests. Its disclosures detail the cost of electricity and gas, infrastructure construction costs, operating costs, and segment-level profit before finance income and taxes. This segmentation shows how CEMIG combines regulated distribution and transmission activities with generation, trading and gas operations under a single corporate group.

The company’s electricity distribution activities are conducted mainly through Cemig D, which reports a billed electricity market that includes captive clients and energy transported for free clients and distributors. CEMIG’s filings describe volumes for residential, industrial, commercial and services, rural, public services and concession holders, along with own consumption. The company also reports on energy transported for free clients and other distributors, and tracks total volume carried through its distribution network, including distributed generation and network losses.

On the generation and transmission side, CEMIG consolidates information for Cemig GT and other related entities. Its segment reporting includes net revenue from generation and transmission, costs of electricity, people-related expenses, materials and outsourced services, depreciation and amortization, and operating provisions. The company also discloses information on infrastructure construction costs related to its regulated activities, particularly in distribution and transmission, which appear as specific cost lines in its financial statements.

Ownership and corporate structure

CEMIG is described in its own materials as a state-controlled mixed capital company, with the State of Minas Gerais identified as the controlling shareholder. CEMIG GT is presented as a wholly owned subsidiary of CEMIG Holding. The group structure allows CEMIG to operate through specialized entities for generation and transmission (Cemig GT), distribution (Cemig D), and gas (Gasmig), while maintaining consolidated reporting at the holding level. The company also holds equity interests in other entities, which are reflected in its segment for equity interests and in its line item for gain or loss in non-consolidated investees.

CEMIG’s governance framework includes a Board of Directors, a Fiscal Council and executive management, with shareholder participation through ordinary and extraordinary shareholders’ meetings. The company’s filings describe procedures for remote voting, digital participation in meetings, and documentation requirements for individual and institutional shareholders, illustrating the governance and shareholder engagement mechanisms applicable to a publicly held company in Brazil.

Electricity market and client base

In its interim financial information, CEMIG provides detailed data on its consolidated electricity market. The group reports that it invoices a large client base composed mainly of final consumers and a smaller number of other agents in the Brazilian electricity sector. Its disclosures break down billed electricity to captive clients and energy transported for free clients and distributors, with volumes reported in MWh and GWh for different customer categories.

CEMIG’s reporting distinguishes between captive market consumption and energy transported for free clients, and also accounts for distributed generation and network losses. It provides separate figures for residential, industrial, commercial and services, rural and public services segments, as well as concession holders and own consumption. These data illustrate how changes in industrial and commercial demand, migration to distributed generation and the use of the transmission network affect total energy distributed and transported.

Financial reporting and performance metrics

CEMIG’s financial disclosures include net revenue, costs, gross profit, operating expenses, finance income and expenses, and net profit. The company presents both IFRS and adjusted metrics such as EBITDA and profit by company and by segment. It also reports on operational revenue, operational costs and expenses, finance income and expenses, equity income from non-consolidated investees, and consolidated EBITDA, including regulatory adjustments for transmission.

The company’s segment information shows how net revenue and costs are allocated among generation, transmission, trading, distribution, gas and equity interests. It also provides details on people costs, profit sharing, post-employment liabilities, materials and outsourced services, depreciation and amortization, and operating provisions. These disclosures allow investors to see how CEMIG’s different business lines contribute to consolidated profit before finance income and taxes, and to net profit.

Capital markets presence and dividends

CEMIG states that it is a publicly held company with shares traded on the stock exchanges of São Paulo and New York, and that its shares have also traded on the Madrid stock exchange’s Latibex segment.

The company characterizes this delisting as aligned with a strategy of simplification.

In its notices to shareholders, CEMIG describes the declaration and payment of interest on equity (IoE) and dividends related to specific fiscal years. It explains that IoE payments are subject to income tax withholding, except for exempt shareholders under applicable legislation, and that payments are processed through its share custodian bank and the Brazilian clearing and custody infrastructure. These communications illustrate the company’s approach to shareholder remuneration and the operational details of distributing proceeds to investors.

Regulatory environment and legal matters

These disclosures show that CEMIG’s operations are closely linked to Brazilian regulatory bodies, including the Brazilian Securities and Exchange Commission (CVM), B3 S.A. – Brasil, Bolsa, Balcão, and sector entities such as the Electric Energy Trading Chamber (CCEE). The company repeatedly states that it will inform shareholders and the market in accordance with CVM rules and applicable legislation, emphasizing its obligations as a listed utility under Brazilian and international securities regulations.
