Income Statements

Consolidated Energy Market

The Cemig Group billed approximately 9.6 million customers in March 2026, adding 161,000 new customers YoY, up by 1.7%. Of this total, 9,624,850 are end-users and self-consumers, and 623 are other players in the Brazilian energy sector.

In the chart below, you can see the breakdown of the Cemig Group’s sales to end-users:

Billed Energy Market

Energy supplied to captive customers, combined with energy transported to free market customers and distributors—excluding DG-offset energy—totaled 11,608 GWh in 1Q26, down 3.2% YoY. This result was primarily driven by lower consumption in the industrial (-351.6 GWh, -6.2%), rural (-35.5 GWh, -6.4%), and commercial (-59.8 GWh, -3.7%) segments, reflecting customer migration to distributed generation (DG) and the basic grid, as well as higher rainfall during the period, which reduced irrigation needs. In contrast, residential consumption increased (+87.9 GWh, +2.6%), reflecting growth in the number of customers.

Distributed energy, excluding DG, decreased by 3.2% driven by a 4.0% decline (-222.8 GWh) in captive market consumption and a 2.5% decline (-163.9 GWh) in grid usage by free-market customers.

When including DG-offset energy, total distributed energy decreased by 0.4% compared to the same period last year.

Performance by Sector

Industrial: Energy distributed to industrial customers decreased by 6.2%* YoY and accounted for 45.5%* of Cemig D’s total. The majority relates to energy supplied to industrial free-market customers (44.4%), which declined by 5.2% YoY. Meanwhile, billed energy for captive customers, representing 1.1% of total distribution, decreased by 35.7% YoY, primarily due to customer migration to the free market.

The decline in industrial consumption was significantly impacted by the migration of two major customers to the basic grid. Excluding this effect, distributed energy would have declined by 1.5%. Lower consumption in the quarter was primarily driven by Steel (-41.6%), Chemicals (-34.9%), and Ferroalloys (-11.4%), while Non-Ferrous Metals (+12.2%), Extractive Industry (+9.5%), and Food and Beverages (+4.0%) segments reported growth in consumption.

Residential: Residential consumption, representing 29.4%* of Cemig D’s distributed energy, increased by 2.6% YoY, driven by a 2.9% growth in the customer base (+230,200), partially offset by a 1.3% decline in average consumption per customer.

Commercial and Services: The commercial segment accounted for 13.3%* of Cemig D’s distributed energy in 1Q26 and declined by 3.7% YoY. This reflects a 12.4% drop in captive customer volumes, partially offset by a 7.3% increase in free-market volumes, directly driven by migration to this market. The overall decline in this segment, in turn, was mainly due to customer migration to DG.

Rural: This sector accounted for 4.5%* of total distributed energy and declined by 6.4% YoY, mainly due to higher rainfall in 1Q26 compared to previous year, which reduced irrigation needs.

Public Services: accounted for 6.7%* of distributed energy in 1Q26, and declined by 3.4% YoY.

*Excluding DG-offset energy

Sources and uses of electricity - MWh

Customer Base

In March 2026, 9.6 million consumers were billed, up by 1.9% YoY. Of this total, 6,438 are free customers using Cemig D’s distribution network.

2025 Tariff Adjustment

Cemig D's tariffs are adjusted annually in May, with a tariff review process conducted every five years in the same month. The annual adjustment is designed to fully pass through non-manageable costs and to apply an inflation adjustment to manageable costs, as defined in the tariff review. The adjustment index for manageable costs is IPCA, from which the X Factor is deducted to capture productivity gains, in line with the price-cap regulatory model.

On May 20, 2025, ANEEL approved the result of the Company's Tariff Adjustment, effective from May 28, 2025 through May 27, 2026, with an average impact of 7.78% for consumers. The average effect for low-voltage customers was 7.03%, while for residential consumers it was 6.86%. The adjustment corresponding to the Company's manageable costs (Portion B) had an impact of 1.36 p.p. on the tariff adjustment; non-manageable costs (Portion A) related to energy purchase, transmission, sector charges, and irrecoverable revenues accounted for 6.12 p.p.; and the financial components of the tariff represented an increase of 0.30 p.p. The item with the greatest impact on the tariff adjustment was sector charges, which contributed an effect of 4.63 p.p., driven by the increase in the CDE.

Tariff Review

Highlights of the 2023 and 2018 Tariff Reviews:

* CAIMI: (Cobertura Anual de Instalações Móveis e Imóveis) – Annual support for facilities

* QRR: ‘Regulatory Reintegration Quota’: Gross base x annual depreciation rate

Additional information at:
https://www2.aneel.gov.br/aplicacoes/tarifa/arquivo/NT%2012%202023%20RTP%20Cemig.pdf

OPEX and EBITDA - Actual vs. Regulatory

Performance exceeded regulatory OPEX and EBITDA in 1Q26 by R$65 million and R$61 million, respectively.

Regulatory Ebitda is calculated by reference to: (i) remuneration of capital; (ii) the QRR quota (Gross base x annual depreciation rate); and (iii) a percentage of the Annual Cost of Facilities and Real Estate, published in Aneel Technical Notes at the times of Tariff Reviews and Tariff Adjustments.

Quality Indicators – DEC/FEC

DEC (Equivalent Interruption Duration per Consumer Unit) reached 8.75 hours in 1Q26—a record low and below the regulatory limit of 9.26 hours. This result represents a reduction of 40 minutes compared to the rolling 12-month period ended March 2025. FEC (Equivalent Interruption Frequency per Consumer Unit) remained slightly below the regulatory benchmark of 5.39, reaching 4.99 on a rolling 12-month basis at the end of 1Q26 (vs. 5.14 in December 2025).

Combating Delinquency

The Receivables Collection Index has remained above 99% since 2022, reaching 99.18% in March 2026. This performance reflects the effectiveness of our collection tools and the successful conclusion of key negotiations, leading to improved cash collections from customers.

Digital collections (PIX, direct debit, credit cards, app, etc.) reached 70.18% of total collections, up from 67.17% in March 2025. PIX, the most widely used payment method, accounted for 36% of collections and has generated R$41.0 million in fee savings since its implementation in 2021.

Losses

Energy losses remained below the regulatory target in the 12-month period ended March 2026, reaching 11.41%, compared to a target of 11.48%. Following the tariff adjustment effective May 28, 2025, an enhanced methodology for calculating non-technical loss coverage—defined by ANEEL in Technical Note No. 53/2025—was implemented. The updated methodology includes measured DG energy in the calculation, rather than billed energy, resulting in higher tariff coverage for energy losses.

Key loss-reduction measures implemented in 1Q26 included 74,000 inspections, the replacement of more than 81,000 obsolete meters and 92,000 smart meters (bringing the total to 695,000 since the project’s inception in September 2021). In addition, illegal connections were regularized for households in informal settlements and complex areas using shielded wiring, totaling 27,900 regularizations since the project’s inception in February 2023.

In 2026, the plan calls for 358,000 inspections, 400,000 smart meter installations, replacement of 150,000 obsolete meters, and the regularization of 25,000 households in low-income communities, leveraging BT Zero and Shielded Metering Panel technologies. It also includes expanding capacitor banks to enhance control of technical losses, among other structural initiatives.

Energy Market

Energy sold by both Cemig GT and Cemig Holding, excluding CCEE, grew (+0.5%) YoY, with energy billed by Cemig GT totaling 6,539 GWh (including quota energy), up by 12.0% YoY, and Cemig Holding recording sales of 4,114 GWh, down 13.6% YoY. The migration of third-party purchase contracts from Cemig GT to Cemig Holding began in 3Q21 and has been proceeding gradually since then, having already reached approximately 61%. Of the total sold by the Holding and Cemig GT in 1Q26, 435.7 GWh were sold in the retail market.

Gasmig is the exclusive distributor of piped natural gas in the state of Minas Gerais, serving industrial, commercial, residential, CNG, automotive, and thermoelectric segments. Its concession extends through January 2053. Cemig holds a 99.57% stake.

In April 2022, the Tariff Review process for Gasmig was completed. Highlights were:

The decrease in Gasmig’s EBITDA (-9.6% YoY) was driven by a 3.4% decline in distributed volume and customer migration to the free market, which carries lower margins.

Total volume of gas distributed was 3.4% lower YoY in 1Q26, with volume sold to the captive market down 53.1% (-104,100 m³) and volume distributed to industrial and thermal free-market customers up 167.0% (+95,500 m³). Sales volume declined mainly due to the migration of industrial customers to the free market, leading to higher volumes distributed to this segment. Overall, the industrial segment was the main driver of the decline, with a reduction of 7,000 m³ YoY.

Gasmig saw a 5.2% YoY increase in its client base, reaching 110,842 consumers. This growth was driven by both the residential (+4,000 customers) and commercial (+1,400 customers) segments.

Operating Revenue

Gross Electricity Supply

* Including DG-offset energy

Supply Revenue

Gross revenue from energy supply totaled R$8,995.1 million in 1Q26, compared to R$8,374.4 million in 1Q25, up 7.4% YoY, mainly driven by Cemig D’s annual tariff adjustment effective May 28, 2025, with an average increase of 7.78%.

Transmission

The Company’s transmission revenue consists of operating and maintenance revenue, construction revenue, and financial compensation of the contractual asset. In 1Q26, transmission revenue totaled R$239.5 million, down 20.2% YoY. Revenue from financial compensation of the contractual asset decreased by R$135.1 million due to the lower IPCA in the period (the inflation index used to adjust revenue), while construction revenue increased by R$85.4 million, driven by higher investments.

Gas

Gross revenue from gas supply totaled R$556.4 million in 1Q26, down 39.6% YoY, primarily impacted by the migration of industrial customers to the free market and the resulting reduction in sales volume.

Use of Electrical Distribution Systems - TUSD

In 1Q26, TUSD revenue derived from charges levied on free-market consumers for distributed energy increased by R$81.0 million (+5.7%) YoY. This change reflects the distribution company’s annual tariff adjustment, effective May 2025 and fully reflected in the quarter, as well as higher charges paid by consumers, partially offset by lower volumes transported to free-market customers.

CVA (Variation Compensation Account for “Portion A” Items) and other financial components

Revenue of R$369.6 million was recognized in 1Q26, up 192.6% YoY, mainly driven by higher energy purchase costs and CDE costs exceeding the level set in the tariff adjustment.

Cemig D recognizes in its financial statements the positive or negative differences between actual non-manageable costs and the estimated costs underlying tariff setting. These balances represent amounts to be refunded to consumers or passed through to the Company in future tariff adjustments.

Operating Costs and Expenses

Operating costs and expenses totaled R$9.15 billion in 1Q26, up R$730.8 million (+8.7%). This amount excludes R$26.2 million in other revenue, related to gains on real estate sales and classified as contra-revenue.

This variation was mainly driven by a R$684.4 million increase in purchased energy costs and a R$280.6 million increase in construction costs (reflecting higher investments), partially offset by lower gas purchase costs for resale (-R$275.6 million).

Further details on costs and expenses are provided below:

Energy Purchased for Resale

The consolidated cost of energy purchased for resale was R$4.92 billion in 1Q26, up R$648.4 million YoY. This variation is mainly due to the following factors:

Gas purchased for resale

The cost of gas purchases was R$213.3 million in 1Q26, down 56.4% YoY, primarily due to lower gas purchase volumes for the regulated market, reflecting the migration of major industrial customers to the free gas market.

Third-party services

Expenses with third-party services increased by 15.8% (+R$81.3 million) YoY, primarily driven by the following increases: R$43.4 million (+24.8%) in maintenance, largely due to increased preventive maintenance, R$12.3 million (+17.9%) in information technology, and R$8.8 million (+39.0%) in tree trimming.

Expected credit losses (ECL)

The R$32.8 million YoY increase is partly explained by the change to the threshold for full loss recognition, extended from 24 to 36 months effective August 2024, with a reducing effect phased in over 12 months.

Provisions

Provisions for contingencies totaled R$84.0 million in 1Q26, down R$61.6 million YoY. The decrease is primarily driven by a lower level of labor-related provisions

Post-employment obligations

Expenses related to post-employment obligations decreased by R$52.2 million YoY, and by R$79.9 million excluding the non-recurring effect of the remeasurement of the obligation in 1Q25. This reduction reflects the termination of the health plan obligation, following an agreement with unions and retirees ratified by the Regional Labor Court (TRT) at the end of 2025.

Personnel

Personnel expenses totaled R$365.6 million in 1Q26, up R$19.3 million (+5.6%) YoY. Growth was mainly driven by an approximately 5% increase in the average number of employees between the periods, as well as the annual collective wage adjustment.

Employees and management profit sharing

The expense related to profit sharing was R$45.1 million in 1Q26, up R$1.8 million YoY.

Equity Income

Equity income increased by R$10.2 million in 1Q26 vs. 1Q25. The main driver was the improvement in Belo Monte’s results, reflecting lower operating costs. In addition, following the asset unwinding at the end of 2025, Cemig Sim no longer reports equity income, as all assets are now fully owned.

EBITDA of R$1,788.7 million in 1Q26 represented a 2.1% YoY decrease, while adjusted EBITDA decreased by 0.6%. The main effects in the comparison are as follows:

Cemig D EBITDA

Cemig D reported EBITDA of R$1,010.4 million, up 23.3% YoY. Adjusted EBITDA, in turn, grew 26.7% compared to the same period last year. The main effects on EBITDA in the quarters’ comparison are as follows:

Cemig GT EBITDA

Cemig GT’s EBITDA totaled R$575.6 million in 1Q26, down 23.2% YoY, while adjusted EBITDA decreased by 22.6%. The main effects on EBITDA in the quarter are as follows:

Financial Income and Expenses

The consolidated financial result in 1Q26 represented a net financial expense of R$338.4 million, up R$88.8 million YoY. This performance is mainly due to the following factors:

Net Income

Cemig reported net income of R$979.0 million in 1Q26, compared to R$1,038.7 million in 1Q25. Adjusted net income was 4.1% lower than 1Q25, when it totaled R$1,020.1 million.

As discussed in the previous sections, net income was primarily impacted by the reduction in EBITDA from trading, partly offset by improved performance at the distribution unit. The financial result, in turn, was negative R$338 million, R$88.8 million higher than 1Q25, due to the increase in net debt. Offsetting this factor, the effective income tax rate was lower in 1Q26, influenced by higher declared IoC, amounting to R$658 million in 1Q26 and R$541 million in 1Q25.

Investments totaled R$1.48 billion in 1Q26, up 22% YoY.

The main highlights in 1Q26 were: (i) a R$1.28 billion investment by Cemig Distribuição connecting over 26,000 new customers, building 6 new and expanding 1 substations, constructing 765,000 km of low- and medium-voltage networks, and installing 92,000 smart meters; (ii) a R$103 million investment in transmission reinforcements and improvements, addition of 19 MWp of installed capacity in distributed photovoltaic generation, and the construction of 23.6 km of gas pipelines by Gasmig.

The execution of the largest investment program in Cemig’s history ensures the modernization and reliability of its electric system, in line with the Company’s strategic focus on Minas Gerais and its core businesses, while delivering an even better service to customers. Investments of R$43.70 billion are planned for 2026–2030, including R$6.72 billion in 2026.

The Company maintains disciplined execution of its financial strategy, focused on optimizing cash flow, reducing the cost of capital, and extending its debt maturity profile.

Average debt maturity reached 6.6 years at the end of 1Q26. Notably, 76% of total debt matures in 2029 or later, positioning repayments largely beyond upcoming Tariff Review processes for the distribution and transmission businesses, enhancing predictability and financial flexibility.

Resilience and Financial Flexibility

In a potentially more selective capital markets environment, the Company remains well positioned, supported by its strong credit ratings and the defensive nature of the electric power sector. The capital structure is further reinforced by pre-approved credit lines that can be rapidly deployed during periods of volatility. Management continuously monitors funding alternatives—including multilateral agencies, development banks, receivables discounting, and Law 4,131 loans—enabling the Company to access more favorable market windows. In scenarios of widening spreads, the impact on the overall cost of debt would be limited, as the current liability profile is not directly affected by secondary market movements or NTN-B yields.

Covenant Structure

The Company reiterates that its current covenant levels are appropriate for the maturity of its projects and aligned with industry peers, ensuring security for investors and supporting the sustainability of its operations.

Cemig’s credit ratings have steadily improved in recent years, reaching the highest level in the Company’s history.

In 2025, the Company received an AAA rating from an additional credit rating agency, following a Moody's upgrade, further underscoring its financial strength, consistent performance, and disciplined capital allocation.

The evolution of ratings is shown below:

Cemig has established public sustainability commitments and is implementing strategic initiatives monitored through corporate KPIs and targets. These commitments are structured around five pillars: (i) Energy Transition, (ii) Environment, (iii) Local Development, (iv) Our People, and (v) Strong Governance.

Corporate Highlights

Energy Transition

Cemig reinforces its climate leadership by achieving 100% offsetting of Scope 1 emissions for 2024 ahead of schedule (with 2025 figures still pending) and expects to continue offsetting emissions in the coming years. In parallel, 700 municipalities are now served by dual power supply, in line with the goal of reaching full coverage of municipal seats under this system.

The company was once again selected for the CDP A List, achieving the maximum score in 10 of the 16 evaluated criteria, notably:

Environmental Highlight

The diagnosis of ecosystem services impacts and dependencies for Cemig has been completed. This assessment will support the development of internal strategies to mitigate negative impacts and reduce dependencies, contributing to improved operational processes and the promotion of biodiversity conservation.

Corporate Governance and Risk Management

In recent months, Cemig has advanced its governance practices. For the third consecutive year, the Company obtained the ISO 31000 Statement of Conformity, reinforcing the maturity of its risk management processes. In addition, the 2025–2026 Corporate Risk Matrix was approved, developed through a collaborative process and focused on consolidating key strategic risks under senior management oversight.

Sustainability indicators were reorganized to better align with Cemig’s new Materiality Matrix (pp. 6–7 of the Cemig Sustainability Report), which identifies eight material topics—three considered double material, four financially material, and one impact material. This reorganization strengthens the alignment between reported indicators and the Company’s priority themes, as well as those of its stakeholders.
