\* Excludes supply offset in Distributed Generation.

In 2Q25 electricity billed to captive clients, plus transport of energy for Free Clients and distributors, excluding supply offset in Distributed Generation, totaled 11,826 GWh – or 3.3% less than in 2Q24. This was mainly the result of lower consumption by industrial clients (–287.9 GWh or –5.0%), commercial clients (–101.3 GWh or –6.2%) and public services (–33.7 GWh or –4.8%). In turn this mainly reflected migration of clients to DG, and to the transmission network. At the same time, consumption by residential clients was +19.7 GWh (+0.6%) higher, and rural consumption was +11.2 GWh (+1.5%) higher.

The reduction of 3.3% in total energy distributed comprised a 6.4% decrease (–381.1 GWh) in consumption by the captive market, and a 0.3% reduction (–18.5 GWh) in use of the network by Free Clients. Taking offset DG energy into account, total distributed energy was 1.0% lower than in 2Q24.

**Performance by sector**

**Industrial** **:** Energy distributed to industrial clients was 5.0% lower than in 2Q24, and was 46.4% of Cemig D's total distribution. The greater part was energy transported for industrial Free Clients (44.9%), which was 3.4% lower in volume than in 2Q25. Within this total, energy billed to captive industrial clients was 1.5% of the total distributed, and 35.7% less by volume than in 2Q24 – mainly due to migration of clients to the Free Market.

The reduction in consumption by industrial users reflects (i) migration of customers to the transmission network, and (ii) lower consumption, in particular by a few sectors: Ferro-alloys (down 9.3% YoY), Chemicals (down 19.2%) and Steel (down10.6%), while there was growth in consumption by Extractive Industries (+6.0%) and Foods and Beverages (+2.5%).

**Residential** consumption was 26.8% of the total energy distributed by Cemig D in the quarter, and 0.6% higher in total volume than in 2Q24. Average monthly consumption per consumer, at 130.9 kWh/month, was 1.9% lower than in 2Q24. On the other hand, the total number of residential clients increased by 2.6% year-on-year (+200,400 new clients).

**Commerce and Services** **:** Energy distributed to and for these consumers was 12.9% of the total distributed by Cemig D in 2Q25, and by volume 6.2% less than in 2Q24. The change has two components: a 17.5% reduction in the volume of energy billed to captive clients, and a 13.7% increase in the volume of energy transported for Free Clients. The lower figure for total consumption mainly reflects migration of clients to Distributed Generation.

**Rural** **:** Consumption by rural clients was 6.6% of the total energy distributed and was 1.5% higher by volume than in 2Q24. This mainly reflected (i) higher consumption for irrigation, and (ii) a reduction of 0.8% in the number of consumer units in this category.

**Public services:** consumed 6.7% of the energy distributed in 2Q25, and 4.8% less by volume than in 2Q24.

**Direct Action of Unconstitutionality No. 7,324 – PIS/Cofins Credits on ICMS**

On August 14, 2025, the Federal Supreme Court (STF) ruled on Direct Action of Unconstitutionality No. 7324, which challenges the constitutionality of Law No. 14,385/2022. This law addresses the reimbursement of taxes overpaid by electricity distribution companies to consumers. The Court confirmed the validity of the law, establishing that the excess amounts must be returned to consumers in the form of discounts on electricity bills. The Company is awaiting the publication of the ruling, at which point there will be sufficient elements to assess the potential accounting, financial, and operational impacts resulting from the decision.

**The 2025 Annual Tariff Adjustment**

The tariffs of **Cemig D** are adjusted in May each year; and every five years are subjected to a Periodic Tariff Review, also in May. The aim of the Annual Adjustment is to pass on changes in the costs defined as "non-manageable" in full, to the client, and provide inflation adjustment for the costs specified as "manageable" in the Tariff Review. Manageable costs are adjusted by the IPCA inflation index, less a factor known as the 'X Factor', designed to capture productivity, under a system using the price cap regulatory model.

On May 20, 2025 Aneel ratified Cemig D's annual Tariff Adjustment, to be effective from May 28, 2025 to May 27, 2026. This resulted in an average increase, for consumers, of 7.78%. The average effect for low-voltage consumers was an increase of 7.03%, and for residential consumers, an increase of 6.86%. The component percentage of the increase corresponding to manageable costs (referred to as 'Portion B') was 1.36%. The increase relating to non-manageable costs ('Portion A' – comprising purchase of energy, transmission, sector charges and non-recoverable revenues) was 6.12%. The increase in the financial components of the tariff contributed 0.30 percentage points. The item with the greatest impact on the tariff increase was the sector charges, which contributed an effect of 4.63%, reflecting an increase in the CDE (the Energy Development Account).

**Indicators of supply quality – DEC and FEC**

In the 12 months to end-June 2025 Cemig's Outage Duration indicator (DEC) was 9.76 hours, higher than the regulatory limit of 9.48 hours. The Company's Outage Frequency indicator (FEC), at 5.37 per year for the 12 months, remained within the regulatory parameter of 5.83 per year.

![](image_153.jpg)

**Combating default**

The Company has maintained a high level of collection actions, which have helped keep the *Receivables Recovery Index* high – it was 98.99% in June 2025.

New payment channels, and online negotiation, have helped to increase the proportion of client payments being made via digital channels (PIX instant payments, automatic debits, payments by card and app, etc.) – which were 67.5% of the total collected in 2Q25, or 0.44 percentage points higher than in 2Q24. A highlight is Brazil's PIX instant payment system, the method most used by clients – which was used for 33.8 % of all client payments, providing savings of R$34.8 million in collection expenses since it was put in place in 2021.

![](image_154.jpg)

**Energy losses**

Energy losses in the 12 months to end-June 2025, at 11.43%, were within the regulatory target level of 11.48%. As from the date of the tariff adjustment (May 28, 2025) Aneel Technical Note 53/2025 updated the method for calculation of non-technical losses to include not only billed amounts of energy but also the volume of Distributed Generation, thus widening the scope of the calculation of energy losses. This change led to an increase in tariff coverage for energy losses.

Highlights of our combat of energy losses in 1H25 include: approximately 177,000 inspections; replacement of more than 173,000 obsolete meters; replacement of 49,000 conventional meters by smart meters (bringing the total of installed smart meters to 419,000 since the project began in September 2021); and regularization of 4,300 clandestine connections made by families living in 'invaded' and low-income areas, through our *Energia Legal* program, which uses 'bulletproofed' networks (bringing the total of connections regularized since the start of the project in February 2023 to 27,100). Planned for 2025 are: 340,000 inspections; replacement of 425,000 obsolete meters; and regularization of 54,000 families in low-income communities (using '*BT Zero'* and '*Bulletproofed Meter Panel*' technologies).

**Cemig GT and Cemig Holding Company**

**Electricity market**

The total volume of electricity sold in 2Q25 by **Cemig GT** and by the holding company (**'Cemig H'**), excluding sales on the Wholesale Power Exchange (CCEE), was 17.6% higher than in 2Q24. **Cemig GT** billed 6,352 GWh (including quota sales) in 2Q25, 31.1% more than in 2Q24.

The **holding company** reported sales of 4,891 GWh in 2Q25, 3.7% more than in 2Q24. The migration of purchase contracts from Cemig GT to the holding company began in 3Q21, and has continued gradually since then. It is now around 61%.

Of the total sold by the holding company and Cemig GT in 2Q25, sales in the **'retail market'** in 2Q25 accounted for **343.4 GWh.**

The volume of gas sold to captive clients in 1H25 was 9.2% (39,500 m³) lower than in 1H24, while the volume distributed to industrial Free Clients and for thermoelectric generation was 121.3% (76,100 m³) higher, resulting in total volume 7.4% higher. Considering 2Q25, total volume was up 11.8% YoY, comprising volume sold to captive clients 11.5% (25,500 m³) lower and volume distributed in the free market 202.3% (54,600 m³) higher.

Gasmig's Ebitda in 2Q25 was 2.8% higher than in 2Q24, reflecting the higher volume of gas distributed to the free industrial customers.

The total number of Gasmig's clients increased by 6.2% from June 2024 to a total of 106,707 consumers in June 2025 – reflecting expansion of both the commercial and the residential client bases (total addition of 6,100 clients).

**Consolidated results**

**Net profit**

For **2Q25,** Cemig reports **net profit** of R$1,188.4 million in 2Q25, which compares to net profit of R$1,688.6 million in 2Q24. **Adjusted net profit** for 2Q25 is R$1,322.3 million, compared to R$1,134 million in 2Q24. The main factors in this result were:

&nbsp;&nbsp;&nbsp;&nbsp;▪ A reduction in
contractual assets, with effect of R$131.3 million in net profit, resulting from remeasurement of the 'RBSE' (national
grid) component, due to the changes made by Aneel Ratifying Resolution 3,469/2025.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Negative impact
of R$46.0 million on profit in the **Trading** activity, due to the exposure of approximately 544 MW **<sub>average</sub>** to differences in spot prices between sub-markets, considering that a significant part of the energy purchased is in the Northeast, and
a part of that energy is sold in the Southeast, Center-West and South markets. The average price difference in 2Q25 was more than R$60/MWh.

&nbsp;&nbsp;&nbsp;&nbsp;▪ There was a net
gain of R$374.9 million from subsidies in Cemig D, arising from the difference between amounts foreseen and realized in the tariff
cycle ended in May 2025, especially the discounts applied to incentive-bearing sources, and Distributed Generation .

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Cemig D** distributed 3.3% less energy in 2Q25 than in 2Q24.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Cemig D's
annual tariff adjustment, valid from May 28, produced an average increase of 7.78%; there was also a gain from the change in Aneel's
methodology for calculating non-technical energy losses (which increased the scope of the calculation to include distributed generation).

&nbsp;&nbsp;&nbsp;&nbsp;▪ The effective
corporate income tax rate was 13.8% in 2Q25, lower than in 2Q24 (21.5%).

&nbsp;&nbsp;&nbsp;&nbsp;▪ Equity income
(share of gain/loss in non-consolidated investees) in 2Q25 was R$38.7 million higher than in 2Q24, reflecting a strong result in **Taesa**.

<u>Effects in 2Q24</u> 

&nbsp;&nbsp;&nbsp;&nbsp;▪ Reversal of tax
provisions – referring to a judgment on Social Security contributions on profit sharing payments – added R$385.7 million
to net profit.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Elimination of
amounts to be repaid to consumers in 2Q24, with counterpart in finance income: effect of R$271 million on net profit

&nbsp;&nbsp;&nbsp;&nbsp;▪ Posting of a
civil liability provision of R$52.6 million, related to power sales transactions.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Success in legal
action relating to the PAT (Workers' Support Fund): R$50.2 million posted in Finance income; income tax provision reduced
by R$31 million

&nbsp;&nbsp;&nbsp;&nbsp;▪ R$95.3
million negative item in net profit from effect of variation in the US dollar exchange rate on debt in US dollars (net of hedge).

More details of these variations are given below.

---

The consolidated expense on electricity bought for resale in 2Q25 was R$4.57 billion, an increase of +23.1% (R$854.1 million) from 2Q24 This mainly reflects several factors:

&nbsp;&nbsp;&nbsp;&nbsp;▪ Costs of energy
acquired in the Free Market (the largest item in energy costs), at R$1,656.8 million, were R$386.8 million (+30.5%) higher
than in 2Q24, due to needs for higher purchases to meet the higher volume sold by the Trading activity, and to cover contractual agreements.

&nbsp;&nbsp;&nbsp;&nbsp;▪ The cost of energy
acquired in the spot market was R$356.5 million, or 268.3%, higher than in 2Q24. This increase was mainly caused by the increase
in the spot price (PLD) in the Southeast/Center-West submarket, which was not compensated or offset by spot prices in the Northeast and
North submarkets, with an average difference between submarkets of more than R$60 per MW. The Company buys energy in the Northeast
and North and its sales are mostly concentrated in the Southeast and Center-West, generating an exposure to the difference between spot
prices between these sub-markets – with negative effect on profit of the Trading activity. In distribution, the negative effect
of this exposure is mitigated by the *CVA* ('Account Compensating for Variations in 'Portion A' items') –
which provides compensation in the next Annual Tariff Adjustment. In addition, the lower GSF in the quarter (0.95 in 2Q25 and 0.99 in
2Q24) caused a higher need for purchase of energy.

&nbsp;&nbsp;&nbsp;&nbsp;▪ The cost of distributed
generation was R$148.1 million (+21.2%) higher, reflecting an increase in the tariff for buying DG, and a 20.8% increase in the
amount of energy injected into the system – totaling 1,797 GWh in 2Q25 – in turn caused by the rapid expansion of the number
of DG facilities connected (they expanded from 273,000 in June 2024 to 336,000 in June 2025).

Note that for Cemig D, purchased energy is a non-manageable cost: the difference between the amounts used as a reference for calculation of tariffs and the costs actually incurred is compensated for in the next tariff adjustment.

***Charges for use of the transmission network and other system charges***

Charges for use of the transmission network in 2Q25 were R$776.7 million, 4.9% lower than in 2Q24.

In the distribution business this is a non-manageable cost: the difference between the amounts used as a reference for calculation of tariffs and the costs actually incurred is compensated for in the next tariff adjustment.

***Gas purchased for resale***

The expense on acquisition of gas in 2Q25 was R$485.1 million, or 4.7% less than in 2Q24 – mainly reflecting lower volume acquired to meet the demand of the regulated market.

***Outsourced services***

Expenditure on outsourced services was 3.8% (R$19.3 million) higher than in 2Q24, with the following increases as the main factors: tree pruning, R$5.2 million (25.3%) higher; outsourced labor, R$5.2 million (42.7%) higher; and costs of disconnecting and reconnecting consumers' supply R$2.9 million (18.7%) higher.

***Client default provision***

The expense on provisions for losses due to client default in 2Q25 was R$3.1 million, or R$74.2 million less than in 2Q24.This (i) reflects the Company's actions in combating default, and (ii) results from the revision, in 3Q24 (with positive effect in the subsequent 12 months), of the criteria for accounting overdue client receivables (increasing the threshold for posting a 100% loss from 24 to 36 months, to give a more faithful estimate of the actual market practice in client payment of past due receivables)**.**

***Provisions***

New provisions of R$113.6 million were posted in 2Q25. This compares with a R$454.2 million reversal of provisions in 2Q24. The main component in that amount was a reversal of R$584.3 million, in 2024, for a first instance court decision in relation to Social Security Contributions.

 ****

***People***

Expenditure on personnel was R$388.4 million in 2Q25, 6.8% less than in 2Q24. This reflects lower expense on the voluntary dismissal program in 2Q25, at R$25.4 million, compared to R$78.1 million in 2Q24. Excluding this effect, other main factors in the comparison were: (i) the 4.6% salary increase under the Collective Work Agreement of November 2024; and (ii) also, a lower transfer of personnel costs to investment in 2Q25.

| **Net finance income (expenses)** | **–262960** | **118119** | **–322.6%** |

---

For 2Q25 the Company posted consolidated net financial expenses of R$263.0 million, compared to net financial revenue of R$118.1 million in 2Q24. Main factors:

&nbsp;&nbsp;&nbsp;&nbsp;▪ Borrowing costs,
and monetary updating of debentures, were a total of R$151.5 million higher, reflecting growth of approximately 30% in gross debt,
and the increase in the Selic basic interest rate.

&nbsp;&nbsp;&nbsp;&nbsp;▪ In 2Q24 there
was a R$410.6 million write-down of liabilities posted as "Repayable to consumers", with counterpart in Finance income
– since the amount estimated by Cemig D for updating of the liability was higher than the amount calculated by using the criteria
used by Aneel. In 2Q25, financial revenue of R$4.3 million was recognized for updating of credits due to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Also in 2Q24
there was a financial expense of R$214.5 million, from the effect on US dollar-denominated debt of 11.26% appreciation of the US dollar
against the Real. There was no such effect in 2Q25, since the debt in US dollars was settled in full in December 2024.

Equity income grew by R$38.7 million in 2Q25 compared to 2Q24. The main effects were (i) a stronger result in Taesa, and (ii) a weaker result in Belo Monte, due to higher finance expense (as a result of the higher TJLP (long-term interest rate) in 2Q25) and an increase in operating costs, which were impacted by an onerous contract related to the difference between the volumes of energy contracted for purchase and sale in future electricity transactions.

**CONSOLIDATED EBITDA (IFRS, and Adjusted)**

Ebitda is a non-accounting metric, prepared by the Company, reconciled with its consolidated financial statements in accordance with the specifications in CVM Circular SNC/SEP 01/2007 and CVM Resolution 156 of June 23, 2022. It comprises: Net profit adjusted for the effects of: (i) Net finance income (expenses), (ii) Depreciation and amortization, and (iii) Income tax and the Social Contribution tax. Ebitda is not a metric recognized by Brazilian GAAP nor by IFRS; it does not have a standard meaning; and it may be non-comparable with metrics with similar titles provided by other companies. Cemig publishes Ebitda because it uses it to measure its own performance. Ebitda should not be considered in isolation or as a substitute for net profit or operational profit, nor as an indicator of operational performance or cash flow, nor to measure liquidity, nor the capacity for payment of debt. The Company adjusts its Ebitda (calculated in accordance with CVM Instruction 156/2022) to exclude extraordinary items which, by their nature, do not contribute to information on the potential for gross cash flow generation.

Cemig D posted 2Q25 **Ebitda** of R$1,209.8 million, 9.0% lower than in 2Q24. Adjusted Ebitda, at R$1,214.4 million, was 39.2% higher than in 2Q24.

Effects on Ebitda in this YoY comparison:

&nbsp;&nbsp;&nbsp;&nbsp;▪ The annual Tariff
Adjustment, in force from May 28, 2025, provided a positive effect, as also did the change made by Aneel to its method of measuring non-technical
losses – in which Aneel widened the scope of the calculation to include Distributed Generation, which increases effective loss coverage

&nbsp;&nbsp;&nbsp;&nbsp;▪ The provision
for client default in 2Q25, including expected loss on other receivables, was R$48.3 million lower than in 2Q24.

&nbsp;&nbsp;&nbsp;&nbsp;▪ A net gain of
R$374.9 million was recognized, for an adjustment related to the difference between amounts forecast and realized in the last tariff
cycle, especially in the discounts applied to incentive-bearing generation sources and Distributed Generation.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Restatement of
post-employment liabilities, with a positive effect of R$16.2 million on Ebitda, due to migration of 557 employees to the Premium
Health Plan (which creates no post-employment obligation for the Company) during the window reopened for joining in April.

&nbsp;&nbsp;&nbsp;&nbsp;▪ New Replacement
Value (VNR) of R$26.6 million in 2Q25, vs. R$22.3 million in 2Q24.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Total energy
distributed (excluding DG) was 3.3% lower than in 2Q24 (comprising 6.4% less in the captive market, and 0.3% less in the Free Market),
mainly due to migration to DG in general, and in particular migration of two large-scale clients to the Free Market. If we include distributed-generation
offsets, total energy distributed was 1.0% less than in 2Q24.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Expense on the
voluntary severance program was R$20.8 million in 2Q25 and R$56.5 million in 2Q24.

&nbsp;&nbsp;&nbsp;&nbsp;▪ The net expense
on deactivation and disposal of assets was R$52.0 million higher than in 2Q24.

&nbsp;&nbsp;&nbsp;&nbsp;▪ In 2Q24 there
was a R$513.3 million reversal of provisions for a first instance judgment in favor of the Company in a case related to Social Security
Contributions.

2Q25 Adjusted Ebitda of **Cemig GT** was R$404.3 million, 37.0% lower than in 2Q24. Adjusted Ebitda was 5.6% lower. Effects on Ebitda in this YoY comparison:

&nbsp;&nbsp;&nbsp;&nbsp;▪ Negative impact
in the *Trading* activity due to exposure to differences in spot prices between submarkets (averaging more than R$60/MWh in
2Q25). This reflects that a significant part of the energy purchase is in the Northeast, while much of the sales are in other submarkets.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Recognition of
a reduction of R$198.9 million in the value of contractual assets, net of PIS, Pasep and Cofins taxes, resulting from remeasurement
of the financial component of assets in the national grid, under the changes made by Aneel Ratifying Resolution 3469/2025.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Equity income
(gain/loss in non–consolidated investees) R$16.9 million weaker, led by a weaker result in  ***Belo Monte*** result,
due to higher finance expenses caused by the increase in the TJLP (long-term) interest rate in 2Q25.

&nbsp;&nbsp;&nbsp;&nbsp;▪ A lower GSF in
the quarter (0.95 in 2Q25, vs. 0.99 in 2Q24) caused a greater need for purchase of energy.

&nbsp;&nbsp;&nbsp;&nbsp;▪ The expense on
the voluntary severance program in 2Q25, at R$3.7 million, was lower than in 2Q24 (R$15.5 million).

&nbsp;&nbsp;&nbsp;&nbsp;▪ Migration of
employees to the Premium Heath Plan (which causes no post-employment obligation for the Company) caused a positive effect of R$4.5 million
in Ebitda.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Excluding spot
sales in the CCEE (wholesale Energy Exchange), the volume of energy sold was 31% more than in 2Q24.

**Investments**

Capex in the first half of 2025 totaled **R$2.75 billion,** 12.6% more than in 1H24. Realized investment in 2Q25 totaled **R$1.54 billion.**

Highlights in 1H25 were: Investment of R$2.16 billion by Cemig D (Distribution), (i) connecting more than 82,000 new clients, (ii) energizing 9 substations, (iii) installing more than 49,000 smarts, and (iv) adding 2,600 km of medium and low voltage networks; in Transmission, investment of R$173 million in strengthening and enhancement of the power line network; in solar Distributed Generation, addition of 21 MWac of installed capacity – and construction of 100 km of gas pipelines by Gasmig.

Execution of the largest investment program in Cemig's history will modernize its electricity system, ensuring reliability, in line with its strategic plan of focusing on Minas Gerais and on its core businesses, and providing ever-improving service to the client. Investment totaling R$39.20 billion is planned for the period 2025–29, of which R$6.35 billion is being invested in 2025.

Cemig highlights

▪ Digitalization
of service channels

80% of customer service encounters between Cemig and its clients now take place via digital channels – a significant advance in modernizing processes and the efficiency of our corporate governance. This digital transformation helps increase transparency, reduce operational costs and improve clients' experience.

Environment

&nbsp;&nbsp;&nbsp;&nbsp;▪ Combating fire
and protecting the power grid.

In 2024, Cemig suffered 1,240 fire-caused events, affecting around 1.5 million people in Minas Gerais. To reduce the risk of outages, in 2025 the Company announced preventive actions and a robust budget for tree pruning and power grid maintenance.

▪ Investments in preventive maintenance

The Company is investing R$360 million in preventive maintenance in 2025, focusing on modernization of substations, strengthening of networks and actions against extreme weather events. More than 3.6 tons of telecommunication cables improperly installed on electricity poles were also removed, contributing to safety, visual quality and proper functioning of electricity infrastructure.

Social

Expansion of the Social Electricity Tariff

▪ Cemig now serves
more than 1.5 million families charged at the Social electricity rate (*Tarifa Social de Energia Elétrica* – TSEE),
which offers up to 65% discount on the client's electricity bill. The Company has intensified communication actions
to expand access to the program. In this quarter alone, 93,000 clients in the Zona da Mata region were included in the benefit.

Energy efficiency in hospitals and healthcare centers

▪ A total of R$1.1
million has been invested in modernizing the lighting of 137 health units in Belo Horizonte, with replacement of existing lamps by more
efficient models. This reduces energy consumption, while improving working conditions for healthcare professionals.

▪ R$493,000
was allocated to replacing an autoclave at the Eliane Martins Municipal Hospital in Ipatinga. The new technology makes sterilization faster
and safer, with an average saving of 52.57 MWh per year.

▪ Solar generation
was installed at the Nossa Senhora dos Anjos Hospital in Itambacuri, to reduce costs.

Menstrual Dignity campaign; Volunteering

▪ Expanding its
commitment to gender equity and social inclusion, the Cemig Volunteering Program organized a campaign to collect menstrual hygiene items,
for free distribution, promoting citizenship and awareness about menstruation, combating any associated stigma, and improving health for
people in situations of vulnerability.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Ebitda is a non-accounting measure prepared
by the Company, reconciled with the consolidated interim financial information in accordance with CVM Circular SNC/SEP n. 1/2007 and CVM
Resolution n. 156 of June 23, 2022. It comprises Net income adjusted by the effects of net financial revenue (expenses), Depreciation
and amortization, and Income and Social Contribution taxes. Ebitda is not a measure recognized by Brazilian GAAP nor by IFRS; it does
not have a standard meaning; and it may be non-comparable with measures with similar titles provided by other companies. The Company publishes
Ebitda because it uses it to measure its own performance. Ebitda should not be considered in isolation or as a substitution for net income
or operational income, nor as an indicator of operational performance or cash flow, nor to measure liquidity nor the capacity for payment
of debt.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The Company adjusts the Ebitda for a better
understanding of how its operating performance was impacted by extraordinary items which, because of their nature, do not contribute towards
information on the potential of future cash generation.

The Company's Adjusted EBITDA decreased by 15.23%, primarily due to the recognition of a reduction in the contract asset, totaling R$198,895, net of PIS/Pasep and Cofins, resulting from the remeasurement of the Existing System Basic Network (RBSE), following the changes introduced by Homologation Resolution No. 3,469/2025. Further details are provided in the transmission segment performance commentary.

By excluding non-recurring effects through Adjusted EBITDA, there was a 15.42% increase, primarily driven by the following factors:

Recognition of tariff subsidy revenue in the amount of R$374,909, net of PIS/Pasep and Cofins, resulting from increased discounts granted by Cemig, primarily to the "Incentivized Source Load" and "GD II" customer classes. Further details are provided in the distribution segment performance commentary; and

The Company's exposure to price differences between sub-markets, which negatively impacted the trading activity by R$69,091, net of PIS/Pasep and Cofins. Further details are provided in the trading segment performance commentary.

<u>Residential</u>

**Residential energy consumption increased by 3.23%** in the second quarter of 2025 compared to the second quarter of 2024, totaling 114,881 MWh. This variation is primarily driven by a 23.65% increase in the volume of energy offset through net metering by micro and mini distributed generation customers — 497,451 MWh in Q2 2025 versus 402,294 MWh in the same period of the previous year.

<u>Industrial</u>

**Industrial grade consumption increased by 5.32%**, or 236,355 MWh, in the second quarter of 2025, compared to the same period of the previous year. This growth is mainly composed of the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;▪ **An increase of 22.12%**,
or 442,185 MWh, **in the supply of energy to free customers**,
due to the price adjustment of the contracts, which are mostly updated at the beginning of the year.

&nbsp;&nbsp;&nbsp;&nbsp;▪ On the other hand, there was
a **reduction of 35.69%**,
or 99,374 MWh, in the **consumption of captive customers of the industrial class**, mainly due to the migration
of customers to the free market.

<u>Commercial, services, and others</u>

Consumption within this customer class **increased by 4.39%** in the second quarter of 2025 compared to the same period of the previous year. This growth was primarily driven by the retail segment, due to contract price adjustments, most of which are indexed and updated at the beginning of the fiscal year.

**Revenue from use of network – Free Consumers**

This is the revenue from charging Free Consumers the Tariff for Use of the Distribution System (*Tarifa de Uso do Sistema de Distribuição*, or TUSD) on the volume of energy distributed. In the second quarter of 2025, this revenue amounted to R$1,414,496, compared to R$1,251,554 in the second quarter of 2024, representing a **13.02% increase**. This variation is primarily attributable to the annual tariff adjustment applied by the distribution company.

**CVA and *Other financial components* in tariff adjustments**

Cemig D recognizes in its interim financial statements the positive or negative variances between actual non-manageable costs and the estimated costs used as the basis for tariff setting. These balances represent amounts that must either be reimbursed to consumers or recovered by Cemig D in future tariff adjustments. The primary purpose of the CVA (Cost Variation Account) is to restore the economic and financial balance of distribution companies.

![](image_194.jpg)

In the second quarter of 2025, a revenue of R$70,394 was recognized, compared to an expense of R$56,556 in the same period of 2024. This variation is mainly due to the increase in energy settlement costs at the CCEE (Electric Energy Trading Chamber).

More information on the composition and movement of CVA can be found in note 9.3.

**Distribution Construction Revenue**

The construction revenue, associated with construction of infrastructure for the distribution concession of energy and gas in 2Q25 totaled R$1,324, compared to R$1,154,213 in the same period of 2024, an increase of 14.75%. This variation is mainly due to the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;▪ an
increase in the number of projects, mainly related to electricity distribution networks, in line with the **Distribution Development Plan (PDD)**, resulting
in construction revenue of R$1,231,705 in the second quarter of 2025, compared to R$1,078,688 in the second quarter of 2024, an increase
of 14.19%; and

&nbsp;&nbsp;&nbsp;&nbsp;▪ an
increase in the number of projects carried out by Gasmig, in line with the **Centro-Oeste Project**, which foresees the construction
of an additional 300 km of gas pipelines. In the second quarter of 2025, construction revenue totaled R$92,741, compared to R$75,525
in the same period of the previous year, an increase of 22.80%. The project is scheduled for completion in the second half of 2026.

These revenues is fully offset by construction costs, of the same amount, and corresponds to the investments by Cemig D and Gasmig in assets of the concession in the period.

![](image_194.jpg)

**Transmission concession revenue**

The Company's transmission revenue is composed of: (i) Operation and Maintenance (O&M) Revenue; (ii) Construction Revenue and (iii) Financial Remuneration of the Contractual Asset.

This revenue totaled R$323,743 in the second quarter of 2025, compared to R$319,037 in the same period of the previous year, representing an **increase of 1.48%**.

**Taxes and regulatory charges reported as deductions from revenue**

Taxes and charges on revenue in 2Q25 totaled R$3,490,507, compared to R$3,427,961 in 2Q24 –a **reduction of 1.82%**.

**Costs and expenses**

Operational costs and expenses in 2Q25 were R$9,222,663, compared to R$7,441,898 in 2Q24, representing an **increase of 23.93%**. The main variations in components of this total are as described below.

**Energy bought for resale**

The cost of electricity purchased for resale is composed as follows:

![](image_186.jpg)

The cost of energy purchased for resale in 2Q25 was R$4,547,303, which compares to R$3,693,227 in 2Q24, an **increase of 23.13%**. The main factors here were:

&nbsp;&nbsp;&nbsp;&nbsp;▪ There was a **30.46% increase** in the cost of energy purchased in the free market, totaling R$1,656,838 in the second quarter of 2025,
compared to R$1,269,988 in the second quarter of 2024. This increase was mainly due to the higher purchase volume required to offset
energy deficits in relation to contracted commitments, as well as the rise in market prices in 2025.

<br>**7**<br>Av. Barbacena, 1200 – Santo Agostinho – 30190-131 Belo Horizonte, MG – Brazil – Fax (+55-31) 3506-5026 – Tel.: (+55-31) 3506-5024<br>**This text is a translation, provided for information only. The original text in Portuguese is the legally valid version.**<br>

![](image_194.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;▪ In the second quarter of 2025, there was **a 268.29% increase** in short-term energy costs, totaling R$489,394 compared to R$132,881 in the second
quarter of 2024. This increase was mainly driven by the sharp rise in the PLD (Settlement Price for Differences) in the Southeast/Central-West
submarket, which was not offset by the PLD in the Northeast and North submarkets.

In the trading activity, the Company's exposure to price differences between submarkets negatively affected the results. Further details can be found in the 'Trading Segment Performance' section.

In the distribution activity, the negative impact of this exposure is mitigated by the CVA mechanism, which is offset in the subsequent tariff adjustment. Additionally, the unfavorable hydrological scenario in the second quarter of 2025 resulted in a low average MRE (Energy Reallocation Mechanism) of 0.95, compared to 0.99 in the same period of the previous year, leading to an increase in the values passed through related to Hydrological Risk.

&nbsp;&nbsp;&nbsp;&nbsp;▪ a **21.22% increase** in the cost of **distributed generation**,
totaling R$846,075 in the second quarter of 2025, compared to R$697,974 in the second quarter of 2024. This variation is due to the increase
in the number of generating installations (336,669 in the second quarter of 2025, compared to 273,174 in the second quarter of 2024)
and the higher volume of energy injected into the grid (1,797 GWh in the second quarter of 2025, compared to 1,487 GWh in the second
quarter of 2024).

![](image_194.jpg)

**Revaluation of the Existing System Basic Network (RBSE)**

In June 2025, Aneel published ReH No. 3,469, which amended the Allowed Annual Revenue (RAP) related to the financial component of the assets of the Existing System Basic Network (RBSE), previously approved by ReH No. 2,852/2021. As a result, the Company carried out a revaluation of the RBSE contractual asset, recording a reduction of R$219,168 in the contractual asset. Further details can be found in explanatory note No. 10.

**Expected credit losses**

In the second quarter of 2025, there was a **95.99% reduction** in expected credit losses, amounting to R$3,098, compared to R$77,300 in the second quarter of 2024. This variation is mainly due to the change, effective from August 2024, in the time limit for full recognition of losses—from 24 to 36 months for regular consumption customers, and from 12 to 18 months for irregular consumption customers—in order to achieve a more accurate estimate of credit risk exposure for Cemig D's captive customers. This change is reflected over a 12-month period, impacting the second quarter of 2025. Additional information on the composition of costs, expenses, and other revenues is provided in explanatory note No. 22.

**Net finance revenue**

The financial result corresponded to a financial expense of R$262,960 in the second quarter of 2025, compared to a financial income of R$118,119 in the same period of 2024. This variation is mainly associated with the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Monetary variation and debenture charges** 

The total monetary variation and debenture charges represented an expense of R$445,093 in the second quarter of 2025, compared to an expense of R$293,606 in the same period of 2024, representing a 51.60% increase. This variation is mainly due from the contracting of Cemig D's 11th, 12th, and 13th debenture issuances, which increased the Company's debt level and, consequently, these expenses.

The composition of financial income and expenses is presented in explanatory note No. 23.

**Update of taxes refundable to consumers**

The update of tax credits related to PIS/Pasep and Cofins, resulting from the exclusion of ICMS from their calculation basis, and of the liability refundable to consumers is presented at net value.

A net financial income of R$4,345 was recognized in the second quarter of 2025, compared to a net financial income of R$406,414 in the same period of the previous year. In the second quarter of 2024, the remaining balance of the liability 'Amounts refundable to consumers' was written off, as it had been returned through tariff revisions, with a corresponding entry in the financial result, which increased the financial result for that period.

**Net revenue**

Net revenue for this segment increased by 14.91%, reaching R$7,269,939 in the second quarter of 2025 compared to R$6,326,844 in the same period of 2024. The main variations are presented below:

**Revenue from supply of electricity**

Cemig D's revenue from the supply of electricity is composed of energy delivered to captive consumers and energy compensated through micro and mini distributed generation by customers. This revenue was R$6,090,187 in the second quarter of 2025, compared to R$5,881,556 in the second quarter of 2024, representing an **increase of 3.55%**. This variation mainly due to the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;▪ **increase of 4.27% in the average billed price per MWh** (R$853.44/MWh
in the second quarter of 2025 compared R$805.82 in the same period of 2024), primarily due to the annual tariff adjustment of Cemig D,
effective as of May 28, 2024;

&nbsp;&nbsp;&nbsp;&nbsp;▪ **increase of 3.23% in electricity consumption by the residential segment**,
mainly driven from the increase in the amount of energy compensated by customers through micro and mini distributed generation; and

&nbsp;&nbsp;&nbsp;&nbsp;▪ On
the other hand, there was a **35.69% reduction in the industrial class** due
to the migration of captive consumers to the free market.

![](image_194.jpg)

**Revenue from charging - Free Consumers**

**Increase of 12.92%** on revenue from charging Free Consumers the Tariff for Use of the Distribution System (*Tarifa de Uso do Sistema de Distribuição, or TUSD*) resulting from the charges imposed on free consumers for the use of distributed energy. In 2Q25 this revenue was R$1,424,464, compared to R$1,261,441 for the same period in the previous year. This variation results primarily due to the distributor's annual tariff adjustment.

**Construction revenue**

The **Construction revenues** associated with construction of infrastructure for the distribution concession totaled R$1.231.705 in 2Q25, compared to R$1.078.688 in the same period in the previous year, showing an **increase of 14.19%**. This variation is basically due to the increase in the number of works due to the Distribution Development Plan (*Plano de Desenvolvilmenot da Distribuição, or PDD*), mainly in distribution networks. This revenue is fully offset by construction costs and corresponds to the Cemig D's investments in assets of the concession.

**Costs and expenses**

Total costs and expenses for the distribution segment amounted to R$6,314,552 in the second quarter of 2025, compared to R$5,221,703 in the same period of 2024, representing an **increase of 20.93%**. The main changes are presented below.

**Cost of electricity purchased for resale**

There was a **14.65% increase** in the cost of electricity purchased for resale, totaling R$2,917,439 in the second quarter of 2025, compared to R$2,544,751 in the second quarter of 2024. This variation is mainly associated with the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;▪ An **increase of 173.92% in short-term energy costs**, totaling R$333,854
in the second quarter of 2025 compared to R$121,879 in the same period of 2024. This variation was mainly due to the sharp rise in the
PLD (Settlement Price for the Difference) in the Southeast/Central-West submarket, which was not offset by the PLD in the Northeast and
North submarkets. Additionally, the unfavorable hydrological scenario resulted in a low MRE (Energy Reallocation Mechanism). In the distribution
activity, the negative effect of this exposure is mitigated by the CVA mechanism, being compensated in the subsequent tariff adjustment.
Additionally, the unfavorable hydrological scenario in the second quarter of 2025 resulted in a low average MRE (Energy Reallocation
Mechanism) of 0.95, compared to 0.99 in the same period of the previous year.

&nbsp;&nbsp;&nbsp;&nbsp;▪ A **increase of 21.22% in distributed generation costs**, totaling R$846,075
in the second quarter of 2025, compared to R$697,973 in the same period of 2024, mainly due to the increase in the number of generating
installations and the volume of energy injected into the grid.

![](image_194.jpg)

The costs of electricity purchased for resale are non-manageable, and the difference between the reference values used to define tariffs and the actual costs incurred is compensated in the subsequent tariff adjustment.

**Expected Credit Losses**

In the second quarter of 2025, there was a **reduction of 96.99%** in expected credit losses, totaling a provision of R$2,184, compared to a provision of R$72,477 in the same period of the previous year. This difference is primarily due to the change, effective from August 2024, in the recognition period limit for losses, which increased from 24 to 36 months for regular consumption customers, and from 12 to 18 months for irregular consumption customers, aiming to achieve a more accurate estimate of credit risk exposure for Cemig D's captive consumers. This change is reflected over a 12-month period, impacting the second quarter of 2025.

**Provisions for contingencies** 

Cemig D recognized provisions for contingencies in the amount of R$86,353 in the second quarter of 2025, compared to a net reversal of R$459,529 in the same period of 2024.

The main variation occurred in tax-related contingencies, due to the recognition of a provision reversal of R$513,331 in the second quarter of 2024, following a favorable first-instance court decision for the Company, which ordered the cancellation of the charge and the termination of the tax enforcement process related to social security contributions on Profit Sharing (PLR).

**Net financial result**

In the second quarter of 2025, the financial result for this segment was a net expense of R$257,443, compared to a revenue of R$305,458 in the same period of the previous year. This variation is mainly associated with the increase in charges and monetary restatement of debentures, resulting from the issuance of the 11<sup>th</sup>, 12<sup>th</sup> and 13<sup>th</sup> series of debentures, which raised Cemig D's debt level and, consequently, its financial expenses.

More detailed information on the variations and impacts presented in this segment is available in Cemig D's interim financial statements.

**<u>Performance of the Transmission Segment</u>**

The transmission segment recorded a loss of R$2,841 in the second quarter of 2025, compared to a net profit of R$108,947 in the second quarter of 2024. The main variations are described below.

![](image_194.jpg)

![](image_188.jpg)

The reduction in EBITDA for the transmission segment is mainly associated with the recognition of a decrease in the contract asset, in the amount of R$198,895, net of PIS/Pasep and Cofins, resulting from the remeasurement of the Existing System Basic Network (RBSE), due to changes introduced by Homologation Resolution No. 3,469/2025. Further details can be found in explanatory note No. 10.

**Transmission concession revenue**

The Company's transmission revenue is composed of: (i) operation and maintenance revenue, (ii) construction revenue, and (iii) financial remuneration of the contractual asset.

Construction, reinforcement, and infrastructure improvement revenues totaled R$179,130 in the second quarter of 2025, compared to R$104,891 in the same period of 2024, representing a 70.78% increase. This variation is primarily due to the higher volume of investments in reinforcement and improvement works, project development, and the significant supply of high-value equipment.

![](image_194.jpg)

**Construction costs**

The transmission construction cost amounted to R$138,924 in the second quarter of 2025, compared to R$72,720 in the same period of 2024, representing an **increase of 91.04%**. The variation in value mainly reflects the largest volume was invested in reinforcement and improvement works, in the development of projects, with a significant supply of equipment that carries high financial value.

**Remeasurement of the Existing System's Basic Network (RBSE)** 

In June 2025, ANEEL published Resolution No. 3,469, which amended the Allowed Annual Revenue (RAP) related to the financial component of the assets of the Existing System's Basic Network (RBSE), previously approved by Resolution No. 2,852/2021. As a result, the Company carried out the remeasurement of the RBSE contract asset, recording a reduction of R$219,168 in the contract asset. Further details can be found in explanatory note No. 10.

**Finance income (expenses)**

The transmission segment recorded a net financial expense of R$3,207 in the second quarter of 2025, compared to a net financial expense of R$41,764 in the same period of the previous year, representing a 92.32% reduction. Until December 2024, the Company recorded foreign exchange variation on loans related to Eurobonds. In accordance with the Company's policy, the allocation of this expense across segments impacted Generation, Transmission, and Equity Interests. The settlement of the Eurobonds in December 2024 eliminated Cemig's exposure.

Detailed information on the variations and impacts presented in this segment is available in Cemig GT's interim financial statements.

**<u>Performance of the Generation Segment</u>**

The generation segment reported a net income of R$449,724 in the second quarter of 2025, compared to R$315,039, representing a **42.75% increase**, mainly due to changes in the financial result for the period.

This segment recorded net financial income of R$15,614 in the second quarter of 2025, compared to net financial expenses of R$75,996 in the same period of the previous year. Until December 2024, the Company accounted for exchange rate variations on loans related to Eurobonds. The allocation of this expense by segment, in accordance with the Company's policy, impacted the Generation, Transmission, and Holdings segments. The settlement of the Eurobonds in December 2024 eliminated Cemig's exposure.

The cost of electricity purchased for resale amounted to R$1,950,946 in the second quarter of 2025, compared to R$1,469,585 in the second quarter of 2024, representing a 32.75% increase. The main reasons for this increase are detailed below.

**Electricity Costs – Price Differences Between Submarkets**

Due to transmission constraints, flow optimization, and system balancing, the National Interconnected System (*Sistema Interligado Nacional, or SIN*) is divided into four submarkets: South (S), Southeast/Central-West (SE/CO), Northeast (NE), and North (NO).

In addition to its own resources, the Company also relies on energy acquired from third parties to meet market demand. Since 2018, the Company has contracted an average of 900 MW from solar and wind energy projects located in the Northeast to supply most of its load, which is concentrated in the South and Southeast/Central-West submarkets. The current composition of the Company's energy portfolio results in a surplus in the Northeast submarket and a deficit in the Southeast/Central-West submarket. Due to transmission constraints between submarkets, short-term prices may vary across regions.

The price received for the sale of surplus energy in the Northeast and the price paid for energy acquired to cover the deficit in the South and Southeast/Central-West is measured by the PLD (Settlement Price for the Differences) established for each of these submarkets. When the PLD is the same across submarkets, there is no impact on the Company's results. However, in the second quarter, due to transmission constraints between submarkets, combined with changes in the system operation planning model and low inflows, there was a price divergence among the submarkets.

---

As presented in the previous table, during the second quarter of 2024, despite the Company's exposure to submarkets, there was no difference between the PLDs of the SE/CO, South, and Northeast submarkets, resulting in no impact on earnings. In the second quarter of 2025, however, the price differences between submarkets negatively affected the Company's results by R$76,133, increasing short-term energy purchase costs. This amount represents the residual effect between the sale of surplus energy in the Northeast and the purchase of energy in the South and Southeast submarkets.

The following chart details the Company's exposure, in average MW (MWm), and the price difference between the SE/CO and South submarkets (analyzed jointly) compared to the Northeast submarket.

**<u>Performance of the Gas Segment</u>**

The Gas Segment recorded a net profit of R$150,820 in the second quarter of 2025, compared to R$137,823 in the second quarter of 2024, an increase of 9.43%. This variation was mainly driven by changes in financial results.

In the second quarter of 2025, the Gas Segment recorded financial income of R$4,533, compared to financial expenses of R$11,937 in the same period of the previous year. In fiscal year 2024, Gasmig did not have financial operations with interest eligible for capitalization.

&nbsp;&nbsp;&nbsp;&nbsp;(1) For these CDBs, the Company and its subsidiaries have repo transactions which
state, on their trading notes, the bank's commitment to repurchase the security, on demand, on the maturity date of the transaction,
or earlier.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Overnight transactions are repos available for redemption on the following
day. They are usually backed by Treasury Bills, Notes or Bonds and referenced to a pre-fixed. Their purpose is to settle the short-term
obligations of the Company and its subsidiaries, or to be used in the acquisition of other assets with better return to replenish the
portfolio.

The main events that impacted the Company's total Cash and Cash Equivalents during the first half of 2025 were the debenture issuances by Cemig D and Cemig GT, as well as the investments made by Cemig D and Gasmig.

In March 2025, Cemig GT completed the financial settlement of its 10th debenture issuance, resulting in a cash inflow, net of transaction costs, of R$621,734. In the same month, Cemig D completed the financial settlement of its 12<sup>th</sup> and 13<sup>th</sup> debenture issuance, in March and April, respectively, with cash inflow net of transaction costs, totaling BRL 4,343,302.

Conversely, in line with its current investment policy, the Company invested BRL 2,332,673 in electricity and gas distribution infrastructure during the first half of the year, in addition to paying BRL 1,775,716 in dividends and interest on equity.

Note 25 gives: (i) the exposure of the Cemig and its subsidiaries to interest rate risk and (ii) a sensitivity analysis for financial assets and liabilities. Financial investments in a reserved investment fund are shown in note 24.

The increase in the total amount of Marketable Securities is mainly due to the investment of funds from the financial settlement of Cemig GT's 10th debenture issuance and Cemig D's 12<sup>th</sup> and 13<sup>th</sup> debenture issuance.

Note 25 provides a classification of these marketable securities. Investments in marketable securities of related parties are shown in Note 24.

The Cemig and its subsidiaries consistently classify the income related to these securities as part of the cash flow of the investment activity, because they believe that this is the most appropriate presentation to properly reflect the activities.

**Annual Tariff Adjustment**

On May 20, 2025, ANEEL approved the results of Cemig D's Annual Tariff Adjustment, effective until May 27, 2026. The average impact on consumers was 7.78%, with an average increase of 9.45% for consumers connected to High Voltage and 7.03% for those connected to Low Voltage. For residential consumers connected to Low Voltage, the average adjustment was 6.86%.

---

| | |
|:---|:---|
| **Voltage Level** | **Average Effect on the Consumer** |
| High and Medium Voltage – Group A | 9.45% |
| Low Voltage – Group B | 7.03% |
| **Average Adjustment** | **7.78%** |

---

This result stems from the adjustment of cost components in Parcel A and Parcel B, calculated in accordance with PRORET (Tariff Regulation Procedures), for the determination of the Required Revenue; the inclusion of financial components calculated in the current tariff adjustment to be offset over the following 12 months; and the removal of financial components established in the previous tariff process, which remained in effect until the date of the current adjustment.

<br> In the composition of the average effect, the variation in Parcel A costs contributed 6.12%, the update of Parcel B accounted for 1.36%, reflecting, among other factors, the accumulated IPCA variation of 5.53% from May 2024 to April 2025, and the financial components were responsible for the remaining 0.3%.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Additions in the distribution segment reflect
investments made by Cemig D, in line with the Distribution Development Plan (PDD). The PDD involves the execution of projects linked to
the electric power system, associated with the expansion, reinforcement, refurbishment, and renewal of Cemig D's assets. In the
first half of 2025, highlights included investments in major urban, rural, and complementary service projects totaling BRL 751,695; reinforcement
and refurbishment of medium- and low-voltage networks, as well as operation and maintenance, totaling BRL 374,810; and expansion and reinforcement
of high-voltage infrastructure, totaling BRL 610,663. Additions in the gas segment reflect investments made by Gasmig, in line with the
Centro-Oeste Project, which includes the planned construction of an additional 300 km of gas pipelines, scheduled for completion in the
second half of 2026.

&nbsp;&nbsp;&nbsp;&nbsp;(2) In Note 22c, this amount is presented net of
PIS/Pasep and Cofins.

![](image_194.jpg)

**Distribution Segment**

The amount of additions in the period from January to June 2025 includes R$72,141 (R$35,260 in the first half of 2024) As capitalized financial charges, as presented in note 17. The average rate used to determine the amount of borrowing costs eligible for capitalization was 13.83%. The nature of additions to contract assets and intangible assets is presented in Note 22b.

The capitalization of financial charges is a non-cash transaction, and therefore is not reflected in the Cash Flow Statements.

**Transmission Segment**

**Basic Network of the Existing System (RBSE)**

On June 10, 2025, ANEEL published Resolution No. 3,469, which amended the Allowed Annual Revenue (RAP) related to the financial component of the Basic Network of the Existing System (RBSE) assets, previously approved by Resolution No. 2,852/2021.

<br> The main change involved the application base of the cost of equity used to calculate the component, with the amortization phase being split into two cash flows: one referred to as 'non-contentious' (payments not suspended by injunctions) and the other as 'contentious' (payments suspended by injunctions), with effective payment dates starting on July 1, 2017, and July 1, 2020, respectively, each with a duration of eight years.

<br> As a result, the remuneration based on the cost of equity was applied exclusively to the contentious flow, for the period from 2017 to 2020 (the year of effective payment).

<br> The RAPs approved and processed up to the 2024/2025 cycle were considered finalized, and the residual amounts were accommodated in the remaining payments for the 2025/2026 to 2027/2028 cycles, in uniform flows.

<br> Due to the changes introduced by the resolution, the Company remeasured the RBSE contractual asset and recorded a reduction of BRL 219,168 as of June 30, 2025.

(1) The variation is primarily associated with the
increase in the PLD (Settlement Price for the Difference Market) in the Southeast/Central-West submarket, which was not offset by the
PLD in the Northeast and North submarkets, as these remained at their minimum value for most of the period. Additionally, the unfavorable
hydrological conditions observed in the second quarter of 2025 resulted in a low MRE (Energy Reallocation Mechanism) performance, leading
to higher pass-through amounts related to Hydrological Risk.

(2) Includes the balance of R$13,693 related to drawn risk operations, on June 30, 2025.

The exposure of the Company and its subsidiaries to exchange rate and liquidity risks related to suppliers is disclosed in note 25.

**Borrowing costs, capitalized** 

The subsidiaries Cemig D and Gasmig considered the costs of debentures linked to construction in progress as construction costs of intangible and concession contract assets, as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | &nbsp;&nbsp;**Jan to Jun/2025** | &nbsp;&nbsp;**Jan to Jun/2024** | &nbsp;&nbsp;**Apr to Jun/2025** | &nbsp;&nbsp;**Apr to Jun/2024** |

| &nbsp;&nbsp;**Net effect in income or loss** | **643438** | **459398** | **383331** | **240729** |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) The average capitalization rate was 13.83% in
the period from January to June 2025 (11.26% in the period from the first half of 2024).

The amounts of the capitalized borrowing costs have been excluded from the statement of cash flows, in addition to cash flow of investment activities, as they do not represent an outflow of cash for acquisition of the related asset.

**Restrictive covenants**

There are early maturity clauses for cross-default in the event of non-payment by Cemig GT or by the Company, of any pecuniary obligation with individual or aggregate value greater than R$50 million ("cross default").

&nbsp;&nbsp;&nbsp;&nbsp;(1) Adjusted Ebtida corresponds to earnings before
interest, income taxes and social contribution on net income, depreciation and amortization, from which non-operating income, any credits
and non-cash gains that increase net income are subtracted, to the extent that they are non-recurring, and any cash payments made on a
consolidated basis during such period in respect of non-cash charges that were added back in the determination of Ebtida in any prior
period, and increased by non-cash expenses and non-cash charges, to the extent that they are non-recurring.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Non-compliance with financial covenants implies
non-automatic early maturity. If early maturity is declared by the debenture holders, Gasmig must make the payment upon receipt of the
notification.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Non-compliance with financial covenants implies
early maturity resulting in the immediate enforceability of payment by CEMIG GT of the Unit Nominal Value or Updated Unit Nominal Value
of the Debentures, as the case may be, plus remuneration, in addition to the other charges due, regardless of judicial or extrajudicial
notice, notification or interpellation.

Management monitors these indexes continuously.

**Linked funds under a debenture issue**

On June 30, 2025, the Company had a balance of R$45,106 relating to restricted funds (R$235,206 on December 31, 2024). This growth is essentially associated with Cemig D's 7th issue of debentures.

According to the Fiduciary Assignment Agreement of the 7th debenture issuance, Cemig D must retain, in a restricted account, monthly during the six months preceding the installment's due date, an amount equivalent to one-sixth of the projected value of the installment, averaging R$181,000. These retentions were made between December 2024 and May 2025. In June 2025, the penultimate installment was paid.

Actuarial gains and losses, net of income tax and social contribution, are non-cash items and, therefore, are not reflected in the statements of cash flows.

<br> The amounts recorded under expenses recognized in the consolidated income statement refer to portions of post-employment benefit obligations, totaling R$211,729 in the first half of 2025 (R$243,837 in the first half of 2024).

**Health and Dental Plans**

In January and April 2025, the enrollment period for the new health plan, Premium Plan, was reopened to all active employees participating in the PSI. The Premium Plan is fully funded by the Company. During both periods, a portion of employees migrated to the Premium Plan, reducing the number of active employees covered by the PSI.

In accordance with CPC 33 (R1) / IAS 19, this situation qualifies as a curtailment event, which required the Company to remeasure its post-employment benefit obligations as of March 31, 2025, considering the January 2025 migration window, and as of the reporting date of June 30, taking into account the April 2025 migration window.

The effects and assumptions of the two events related to the curtailment of the health and dental plans are presented in the table below:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| **Consolidated** | **Curtailment June 30, 2025** | **Curtailment June 30, 2025** | **Curtailment March 31, 2025** | **Curtailment March 31, 2025** | **Actuarial Report 2024** | **Actuarial Report 2024** |
| **Consolidated** | **Health Plan** | **Dental Plan** | **Health Plan** | **Dental Plan** | **Health Plan** | **Dental Plan** |
| Discount rate | 11.85% | 11.85% | 12.32% | 12.32% | 12.23% | 12.23% |
| Past service cost | (20637) | (524) | (27159) | (538) |  |  |
| Actuarial losses (gains) | 50164 | (1431) | (58767) | (970) | (518980) | (10387) |

---

The remaining assumptions remained consistent with those presented in 2024. The discount rate as of June 30, 2025 impacted the liability balances, resulting in an actuarial loss of R$50,164 for the health plan and an actuarial gain of R$1,431 for the dental plan.

**Ruling in action to annul a period of validity in a Collective Employee Health Plan Agreement**

On February 19, 2025, the Specialized Collective Employee Agreement section of the Higher Employment-law Appeal Court (TST) published the judgment given in an Ordinary Employment-law Appeal completed on December 9, 2024.

This decision determined cessation, as from December 31, 2023, of the period of validity of the clauses that specified automatic extension, for successive equal periods, of Clause 17 of the Collective Work Agreement of 2010, and Clause 4 of the Collective Work Agreement of 2016. These clauses ensured compliance by the Company of its obligations to pay post-employment benefits of the health plan (PSI) to retirees and active employees.

Due to the specific nature of this matter, the Company and its legal advisors have, at this time, the probability of loss was assessed as possible in these interim financial statements, and therefore did not impact the amounts recorded under post-employment liabilities for the health and dental plans.

The Cemig and its subsidiaries management, in view of the extended period and the Brazilian judiciary, tax and regulatory systems, believes that it is not practical to provide information that would be useful to the users of this interim financial information in relation to the timing of any cash outflows, or any possibility of reimbursements. It is expected that most of the provisioned amounts will be paid out in periods of more than 12 months.

The Cemig and its subsidiaries believe that any disbursements in excess of the amounts provisioned, when the respective claims are completed, will not significantly affect the Company and its subsidiaries' results of operations or financial position.

The main provisions and contingent liabilities are disclosed in note 24 to the financial statements for the year ended December 31, 2024. For the period ended June 30, 2025, except as indicated below, there were no material changes in the progress of the proceedings or in the amounts provisioned.

In the first half of 2025, the main changes in contingent liabilities were related to the following proceedings:

**Consumer Relations**

**Electricity Supply**

In June 2025, the Public Prosecutor's Office of the State of Minas Gerais (MPMG) filed a public civil action seeking the Company's conviction for collective moral damages, as well as an obligation to improve the electricity supply service in a municipality in Minas Gerais. The claim is based on allegations of repeated and prolonged failures in electricity supply across various areas of the municipality. As of June 30, 2025, the amount of the contingency is R$141,807, with the likelihood of loss assessed as possible.

**Regulatory**

The Company and its subsidiaries are involved in regulatory proceedings in which the contingency amounts were revised due to an unfavorable court ruling against the Company. As of June 30, 2025, the amount of these contingencies is R$716,553 (R$636,619 as of December 31, 2024).

**Accounting for energy sale transactions through the Electric Energy Trading Chamber (CCEE)**

Since August 2002, AES Sul Distribuidora has been legally challenging the accounting criteria applied to energy sale transactions in the Wholesale Energy Market (MAE), the predecessor of the Electric Energy Trading Chamber (CCEE), during the rationing period. In February 2006, the Company obtained a preliminary favorable court ruling requiring ANEEL to comply with the distributor's request and, together with CCEE, to reprocess and settle the transactions carried out during the rationing period, disregarding Dispatch No. 288 of 2002.

This measure was to be implemented by CCEE starting in November 2008 and would result in an additional disbursement for the Company related to short-term energy purchase expenses with CCEE. In June 2025, a court ruling was published with votes in favor of the Company's arguments, leading to a reassessment of the likelihood of loss from "possible" to "remote." The amount of the contingency was R$680,844 as of December 31, 2024.

**Other proceedings in the ordinary course of business**

**Breach of contract**

The Company and its subsidiaries are involved in administrative proceedings, which increased during the first half of 2025 due to the approval of expert calculations. As of June 30, 2025, the amount of the contingency is R$283,045 (R$200,153 as of December 31, 2024), with the likelihood of loss assessed as possible.

**Volta do Rio**

The Company and its subsidiary Volta do Rio are defendants in a notice of violation issued in 2022 by the Secretariat of Federal Assets (SPU/CE), which determined that landfills, ripraps, and towers used for the installation of the wind generation system of CE Volta do Rio were located within the beach zone. As a result, the Wind Power Plant Volta do Rio was subject to the following penalties: (i) demolition and/or removal of the structures and installed equipment, if not eligible for regularization; (ii) a monthly fine for each square meter impacted by the installations. The Wind Power Plant Volta do Rio submitted a defense against the notice and filed an administrative appeal. The contingency calculation considers the monthly fine applied to each square meter of the areas that were filled, built upon, or where works, fences, or installations related to the Wind Power Plant Volta do Rio were carried out. As of June 30, 2025, the amount of the contingency is R$496,540 (R$311,432 as of December 31, 2024), with the likelihood of loss assessed as possible.

**Light for All Program**

The Company is involved in disputes regarding alleged damages resulting from supposed contractual breaches during the implementation of part of the rural electrification initiative known as the Light for All Program.

The reduction in the contingent liability is due to the judgment of appeals, during which the Court of Justice of the State of Minas Gerais (TJMG) assigned to the Company the tax burden related to the ISSQN difference, resulting from the increase in the tax base. Consequently, the likelihood of loss was reassessed from possible to probable, for the amount of R$2,868 as of June 30, 2025. On the other hand, the court dismissed the Company's responsibility for the alleged contractual imbalance, and the likelihood of loss was reassessed from possible to remote, for the amount of R$414,067 as of June 30, 2025 (R$335,585 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;20. EQUITY AND REMUNERATION TO SHAREHOLDERS

&nbsp;&nbsp;&nbsp;&nbsp;(1) This income derives from the total additions and amortizations shown in note 9.3.

&nbsp;&nbsp;&nbsp;&nbsp;(2) In May 2024, Cemig D completed the refund of amounts related to the reimbursement of PIS/Pasep and Cofins
tax credits to consumers, which had been returned through tariff adjustments. Accordingly, the revenue recovery related to the realization
of the liability was completed by the second quarter of 2024.

&nbsp;&nbsp;&nbsp;&nbsp;(3) This variation is associated with the increased number of projects carried out by Cemig D, primarily in
electricity distribution networks, in line with the Distribution Development Plan (PDD), and by Gasmig, in line with the Centro-Oeste
Project, which includes an estimated 300 km of additional gas pipelines. The project is expected to be completed in the second half of
2026. ---

&nbsp;&nbsp;&nbsp;&nbsp;(1) This income derives from the total additions and amortizations shown in note 9.3.

&nbsp;&nbsp;&nbsp;&nbsp;(2) In May 2024, Cemig D completed the refund of amounts related to the reimbursement of PIS/Pasep and Cofins
tax credits to consumers, which had been returned through tariff adjustments. Accordingly, the revenue recovery related to the realization
of the liability was completed by the second quarter of 2024.

&nbsp;&nbsp;&nbsp;&nbsp;(3) This variation is associated with the increased number of projects carried out by Cemig D, primarily in
electricity distribution networks, in line with the Distribution Development Plan (PDD), and by Gasmig, in line with the Centro-Oeste
Project, which includes an estimated 300 km of additional gas pipelines. The project is expected to be completed in the second half of
2026. <br>**62**<br>Av. Barbacena, 1200 – Santo Agostinho – 30190-131 Belo Horizonte, MG – Brazil – Fax (+55-31) 3506-5026 – Tel.: (+55-31) 3506-5024<br>**This text is a translation, provided for information only. The original text in Portuguese is the legally valid version.**<br>

&nbsp;&nbsp;&nbsp;&nbsp;(1) The increase is due to the growth
in the number of consumer units in 2025 and the annual tariff adjustment for 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The subsidy under the Electric
Energy Compensation System (SCEE) refers to an amount allocated to cover tariff benefits for consumer units participating in the SCEE,
introduced by ANEEL as part of the 2023 tariff review. The forecast granted in 2023 exceeded the amounts actually accrued, and the adjustment
made in 2024 surpassed the subsidy amount for that year, resulting in a revenue reversal and a lower figure for the first half of 2024.
Additionally, the variation is due to the increase in discounts granted by Cemig, primarily to the "Incentivized Source Load"
and "GD II" consumer classes.

&nbsp;&nbsp;&nbsp;&nbsp;(3) With Provisional Measure No. 1,212/2024,
the funds from Eletrobras' contribution to the CDE (Energy Development Account) were advanced to settle the Covid Account and the Water
Scarcity Account, resulting in a reduction of the direct contributions to the CDE in 2025 compared to 2024.

&nbsp;&nbsp;&nbsp;&nbsp;(4) This subsidy is affected by the
activation of the Yellow and Red tariff flags. During the first half of 2025, the 'Red Flag – Level 1' was triggered in May and
June. In contrast, during the first half of 2024, no tariff flags were activated, with the Green Flag remaining in effect throughout
the period.

&nbsp;&nbsp;&nbsp;&nbsp;(5) The amount allocated to this subsidy
is defined in the Ratifying Resolution issued for each tariff adjustment. The variation is mainly due to the increase in the discounts
granted by Cemig, particularly to the 'Encouraged Source Load' and 'Distributed Generation II' customer classes.

during the first half of 2024, no tariff flags were activated, with the Green Flag remaining in effect throughout the period.

&nbsp;&nbsp;&nbsp;&nbsp;(5) The amount allocated to this subsidy is defined
in the Ratifying Resolution issued for each tariff adjustment. The variation is mainly due to the increase in the discounts granted by
Cemig, particularly to the 'Encouraged Source Load' and 'Distributed Generation II' customer classes.

(1) The variation is mainly associated with the
increase in the PLD (Settlement Price for the Difference Market) in the Southeast/Central-West submarket, which was not offset by the
PLD in the Northeast and North submarkets, as these remained at their minimum value for most of the period. In the trading segment, the
Company's exposure to price differences between submarkets negatively impacted results. Further details are provided in the "Trading
Segment Performance" section. In the distribution segment, the negative effect of this exposure is mitigated by the CVA (Parcel
A Cost Variation Compensation Account) mechanism, which is offset in the subsequent tariff adjustment. Additionally, the unfavorable hydrological
scenario observed in the second quarter of 2025 resulted in low performance under the MRE (Energy Reallocation Mechanism), leading to
an increase in pass-through amounts related to Hydrological Risk.

(2) The increase of 31.96% is mainly due to the
increase in the number of generating units (336,669 as of June 30, 2025, compared to 273,174 as of June 30, 2024) and the volume of energy
injected into the grid (3,673 GWh in the second half of 2025 compared to 2,925 GWh in the second half of 2024).

(3) The price of the gas molecule purchased by Gasmig
is adjusted based on fluctuations in Brent crude oil prices and the exchange rate.

&nbsp;&nbsp;&nbsp;&nbsp;(1) In the first half of 2024, the Company recognized a reversal of tax contingency
provisions in the amount of R$578,740, resulting from a favorable first-instance court decision that ordered the cancellation of the tax
assessment and the termination of the enforcement proceeding related to social security contributions on Profit Sharing (PLR).

&nbsp;&nbsp;&nbsp;&nbsp;(2) This variation results from the change, effective August 2024, in the criteria
for full loss recognition, extending the period from 24 to 36 months for regular consumption customers, and from 12 to 18 months for irregular
consumption customers. The adjustment aims to improve the estimation of credit risk exposure for Cemig D's captive customers. The
impact of this change is recognized over a 12-month period, affecting the second quarter of 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(1) In the second quarter of 2024, the Company recognized a reversal of tax
contingency provisions in the amount of R$578,740, resulting from a favorable first-instance court decision that ordered the cancellation
of the tax assessment and the termination of the enforcement proceeding related to social security contributions on Profit Sharing (PLR).

&nbsp;&nbsp;&nbsp;&nbsp;(2) This variation results from a change, effective August 2024, in the criteria
for full loss recognition. The recognition period was extended from 24 to 36 months for regular consumption customers, and from 12 to
18 months for irregular consumption customers, in order to achieve a more accurate estimate of credit risk exposure for Cemig D's
captive customers. This change is reflected over a 12-month period, impacting the second quarter of 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(1) The book value represents the approximate fair value amount, except for debentures and pension fund deficit
equalization in relation to the amounts as of June 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The fair value presented is net of the transaction costs and anticipated resources presented in note 17.

At initial recognition the Company measures its financial assets and liabilities at fair value and classifies them according to the accounting standards currently in effect. Fair value is a measurement based on assumptions that market participants would use in pricing an asset or liability, assuming that market participants act in their economic best interest. The information applied in the fair value valuation techniques is classified in three levels of fair value hierarchy, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Level 1. Active market:** Quoted prices: A financial instrument is considered to be quoted in an
active market if the prices quoted are promptly and regularly made available by an exchange or organized over-the-counter market, by operators,
by brokers or by a market association, by entities whose purpose is to publish prices, or by regulatory agencies, and if those prices
represent regular arm's length market transactions made without any preference.

![](image_194.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Level 2. No active market:** Valuation technique: For an instrument that does not have an active
market, fair value should be found by using a method of valuation/pricing. Criteria such as data on the current fair value of another
instrument that is substantially similar, or discounted cash flow analysis or option pricing models, may be used. Level 2 is based on
information that is observable, either directly or indirectly. The objective of the valuation technique is to establish what would be
the transaction price on the measurement date in an arm's-length transaction motivated by business model.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Level 3. No active market:** No observable inputs: Fair value is determined based on generally accepted
valuation techniques, such as on discounted cash flow analysis or other valuation techniques, including non-observable data, such as the
measurement at new replacement value (Valor novo de reposição, or VNR). Non-observable data should be used to measure fair
value where significant observable data is not available, admitting situations in which there is little or no market activity at the measurement
date. Non-observable data are developed using the best possible information available in the circumstances, which may include the entity's
own data.

The fair value hierarchy prioritizes information (inputs) from valuation techniques, and not the valuation techniques used for measurement of fair value. In some cases information is used from different hierarchy levels in measurement of fair value, and this is classified entirely in the same level of the fair value hierarchy applicable to the significant information of a lower level. For assets and liabilities that are recognized at fair value on a recurring basis, the Company determines whether transfers have occurred between levels in the hierarchy by re-assessing categorization.

Information on the (i) methodology for calculating the fair value of positions; and, (ii) financial instruments - derivatives, is disclosed in note 31 to the financial statements for the year ended December 31, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;**b)** **Financial risk management** 

**Exchange rate risk**

The Cemig D is exposed to the risk of appreciation in exchange rates, with effect on loans and financing, suppliers (energy purchased from Itaipu).

The impact of foreign exchange fluctuations related to the Itaipu power purchase agreement is mitigated by the account for compensation of variation of parcel A items (CVA).

**Interest rate risk**

The Company and its subsidiaries are exposed to the risk of decrease in Brazilian domestic interest rates. This risk arises from the effect of variations in Brazilian interest rates on net financial income comprised by financial revenues from cash investments made by the Company, and also to the financial assets related to the CVA and other financial components, net of the effects on financial expenses associated to loans, financings and debentures in Brazilian currency, and also sectorial financial liabilities.

Part of the debentures in Brazilian currency comprises financings obtained from various financial agents that specify interest rates taking into account basic interest rates, the risk premium compatible with the companies financed, their guarantees, and the sector in which they operate.

The Company does not contract derivative financial instruments for protection from this risk. Variations in interest rates are continually monitored with the aim of assessing the need for contracting of financial instruments that mitigate this risk.

**Increase in inflation risk**

The Cemig and its subsidiaries are exposed to the risk of an increase in the inflation index. A portion of the debentures as well as the pension fund liabilities are adjusted using the IPCA (Expanded National Customer Price). The revenues are also adjusted using the IPCA and IGP-M index, mitigating part of the Company risk exposure.

<u>Sensitivity analysis</u>

Due to having more liabilities than assets indexed to inflation indicators, the Company is exposed to an increase in these indicators, as represented in the adverse scenario.

Accordingly, based on the estimate that, in a probable scenario, the IPCA will be 4.92% and the IGP-M will be 5.03% as of June 30, 2026, the sensitivity analysis of the effects on results, considering an adverse scenario compared to the probable scenario, is as follows:

&nbsp;&nbsp;&nbsp;&nbsp;26. SALE OF ASSETS

&nbsp;&nbsp;&nbsp;&nbsp;**a)** **Process of sale of 15 PCHs/CGHs** 

On March 17, 2023, Cemig GT published a public auction notice for the divestiture of 15 SHPPs/MPPPs, including 12 assets owned by Cemig GT and 3 by Horizontes Energia S.A., a wholly-owned subsidiary of Cemig GT.

The asset divestiture process to Mang Participações e Agropecuária LTDA, the winning bidder in the auction held on August 10, 2023, was completed on February 29, 2024, after all precedent conditions of the Asset Purchase and Sale Agreement (APSA) were fulfilled. The amount received from the sale was R$101 million.

The purpose of the sale was to meet the guidelines of the company's strategic planning, which calls for the optimization of the asset portfolio, seeking to improve operational efficiency and the best allocation of capital.

In January 2025, a favorable ruling was issued in the public civil action filed against the public auction notice for the sale of the 15 SHPPs/Small Hydroelectric Plants.

In March 2025, a new ruling was issued declaring the previous decision null and void. As a result, the judgment that had upheld the public civil action against the auction notice was overturned. Cemig will continue to participate in the proceedings, which will lead to a new ruling on the merits.

As of the date of these Interim Financial Statements, there have been no impacts on the Company's financial reporting.

&nbsp;&nbsp;&nbsp;&nbsp;27. ASSETS CLASSIFIED AS HELD FOR SALE

The breakdown of assets classified as held for sale, measured at book value, is as follows:

**Onerous transfer of 4 PCH/UHEs**

On September 23, 2024, a public auction notice was published for the compensated transfer of the rights to operate electricity generation services for four HPPs/SHPPs, including one SHPP owned by Cemig GT and three HPPs owned by its wholly-owned subsidiaries: Cemig Geração Sul, Cemig Geração Leste, and Cemig Geração Oeste.

![](image_194.jpg)

On December 5, 2024, Cemig GT held a public auction at B3, with the winning bid submitted by Âmbar Hidroenergia LTDA in the amount of R$52 million, representing a premium of 78.8% over the minimum price of R$29.1 million.

On February 21, 2025, Cemig GT and its wholly-owned subsidiaries—Cemig Geração Leste, Cemig Geração Oeste, and Cemig Geração Sul—signed the Asset Purchase and Sale Agreement (APSA) with Âmbar Hidroenergia LTDA, the winning bidder of the auction.

On May 23, 2025, the Court of Justice of the State of Minas Gerais suspended, until a final and unappealable ruling on the merits, the preliminary injunction issued in the Popular Action case against the auction notice and the contract related to the divestiture of these power plants, thereby reinstating the effects of the auction held on December 5, 2024.

The closing of the transaction is subject to the fulfillment of customary suspensive conditions, including obtaining consent from the Brazilian Electricity Regulatory Agency (Aneel) and the Administrative Council for Economic Defense (CADE).

This divestiture is in line with the guidelines of Cemig's Strategic Planning, which specifics optimization of the portfolio and a better allocation of capital.

&nbsp;&nbsp;&nbsp;&nbsp;28. SUBSEQUENT EVENTS

**CCEE Auction on Generation Scaling Factor (GSF) Credits**

On August 1, 2025, Cemig GT, its wholly-owned subsidiary Cemig PCH S.A., and the Queimado Consortium—of which Cemig GT holds an 82.5% ownership interest—were declared winners in the auction conducted by the Electric Energy Trading Chamber (CCEE) for Generation Scaling Factor (GSF) credits.

The Queimado and Pai Joaquim hydropower plants will be granted a 7-year extension of their concession and authorization terms, while the Irapé plant will be entitled to a 3-year extension. The total disbursement of R$199,378 was made on August 13, 2025.

**Cash Flow Hedge Operation**

On August 11, 2025, Cemig GT entered into a foreign loan agreement in the amount of USD 40 million under Law 4,131/62. Since the Company's functional currency (BRL) differs from the loan currency, a full cross-currency swap was contracted in accordance with its hedge policy, aiming to mitigate exposure to exchange rate fluctuations.

This derivative is being accounted for under hedge accounting treatment, with a notional amount of USD 40 million, equivalent to BRL 218,552.

**Corporate Restructuring**

On August 14, 2025, the Board of Directors authorized Cemig GT to acquire 100% of Cemig H's equity interest in Cemig SIM's share capital, at book value. As of June 30, 2025, Cemig SIM's shareholders' equity amounted to BRL 947,857.

**Acquisition of 51% of the shares of Hidrelétrica Pipoca S.A.**

On August 14, 2025, Cemig GT exercised its preemptive right to acquire 51% of the shares of Hidrelétrica Pipoca S.A. (Pipoca) held by Serena Geração S.A. (Serena Geração), a wholly-owned subsidiary of Serena Energia S.A. (Serena Energia).

This preemptive right, as governed by the Shareholders' Agreement, arises from the transfer of indirect control of Pipoca, which will be triggered following the public auction of Serena Energia's Tender Offer (TO). Therefore, the effectiveness of the transaction is subject to the completion of the TO, as well as the fulfillment of customary precedent conditions applicable to transactions of this nature.

The transaction value is BRL 36.33 million and will be adjusted by 100% of the CDI rate from May 15, 2025, until the date of Serena Energia's TO auction.

The Pipoca SHPP, located in eastern Minas Gerais, has an installed capacity of 20 MW and firm energy of 11.9 average MW.

Currently, Cemig GT holds 49% of Pipoca's shares, and the acquisition of the remaining 51% will result in full ownership of the asset.

**Direct Action of Unconstitutionality No. 7,324 – Amounts to be Refunded to Consumers**

On August 14, 2025, the Federal Supreme Court (STF) ruled on Direct Action of Unconstitutionality No. 7,324, which challenges the constitutionality of Law No. 14,385/2022. This law addresses the reimbursement of overpaid taxes by electricity distribution companies to consumers. The Company is awaiting the publication of the court ruling, at which point sufficient information will be available to assess the potential accounting, financial, and operational impacts resulting from the decision.

**Introduction**

We have reviewed the individual and consolidated interim financial information of Companhia Energética de Minas Gerais – CEMIG ("Company"), included in the Quarterly Information Form (ITR) for the quarter ended June 30, 2025. This information comprises the balance sheet as of June 30, 2025, and the related statements of income and comprehensive income for the three- and six-month periods then ended, as well as the statements of changes in equity and cash flows for the six-month period then ended, including the accompanying explanatory notes.<br>The Company's management is responsible for the preparation of the individual and consolidated interim financial information in accordance with CPC 21 (R1) and IAS 34 – Interim Financial Reporting, issued by the International Accounting Standards Board (IASB), as well as for the presentation of this information in accordance with the rules issued by the Brazilian Securities and Exchange Commission (CVM) applicable to the preparation of Quarterly Information (ITR). Our responsibility is to express a conclusion on this interim financial information based on our review.

**Scope of the Review**

We conducted our review in accordance with Brazilian and international standards on review engagements of interim financial information (NBC TR 2410 – Review of Interim Financial Information Performed by the Independent Auditor of the Entity and ISRE 2410 – Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of interim financial information consists primarily of making inquiries of persons responsible for financial and accounting matters and applying analytical and other review procedures.<br>A review is substantially less in scope than an audit conducted in accordance with auditing standards and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

**Conclusion on the Individual and Consolidated Interim Financial Information**

Based on our review, we are not aware of any facts that would lead us to believe that the individual and consolidated interim financial information included in the aforementioned quarterly information was not prepared, in all material respects, in accordance with CPC 21 (R1) and IAS 34, applicable to the preparation of Quarterly Information (ITR), and presented in accordance with the rules issued by the Brazilian Securities and Exchange Commission.

**Other Matters – Statements of Value Added**

The aforementioned quarterly information includes the individual and consolidated Statements of Value Added (DVA) for the six-month period ended June 30, 2025, prepared under the responsibility of the Company's management and presented as supplementary information for IAS 34 purposes. These statements were subjected to review procedures performed in conjunction with the review of the quarterly information, with the objective of determining whether they are reconciled with the interim financial information and accounting records, as applicable, and whether their form and content are in accordance with the criteria defined in Technical Pronouncement CPC 09 – Statement of Value Added. Based on our review, we are not aware of any facts that would lead us to believe that these Statements of Value Added were not prepared, in all material respects, in accordance with the criteria defined in that Pronouncement and consistently with the individual and consolidated interim financial information taken as a whole.

**Meetings**

In the second quarter of 2025, the Audit Board met 7 times.

**Internal auditing, management of risks and internal controls**

Maintaining a minimum frequency of a year for the updating procedure, the Executive Board and the Board of Directors approved, in 2024, after consideration by the Audit Committee, Cemig's updated Corporate Top Risks for 2024-25.

The Matrix includes 26 Top Risks, including, in this cycle, risks from some of the Company's investees. These risks are continuously monitored by management. The Matrix includes risks from the Distribution, Generation, Transmission, Commercialization, Innovation, Information Technology, People and Corporate Services, ESG (Environmental, Social and Governance), Communication, Financial, Shareholdings and Divestment, Institutional Regulatory and Control and Integrity pillars.

The company has a Risk Committee, created in 2022, linked to and advising the Board of Directors. It was given the duties of analysis of compliance with the requirements of the regulatory and inspection agencies; definition of the principal risks ('Top Risks'), and respective treatment; identification and measurement of action plans and control of the risks identified; and assessment of the limits of tolerance to the risks to which the Company will be exposed.

With regard to responses to relevant risks and those where tolerance limits have been exceeded, the Internal Controls environment has an annual process for reviewing and testing the design of all the internal controls in the Internal Risks Controls Matrix, in order to keep them adherent, up-to-date and evaluated with respect to the adequacy of risk coverage. In the latest cycle, the Company expanded the scope of review and testing to include internal controls related to the Top Risks, in accordance with the same methodological standards and requirements of the COSO (Committee of Sponsoring Organizations of the Treadway Commission) Internal Control – Integrated Framework (ICIF) and the U.S. Sarbanes-Oxley Act (SOX). The actions and investments in the Internal Controls Environment have, in recent years, ensured its effectiveness in the assessment of management and the independent external auditor, demonstrating confidence in the Company's risk management.

![](image_194.jpg)

Furthermore, the Company maintains an internal audit function, responsible for the preparation and execution of the Annual Internal Audit Plan, which is validated by the Audit Committee and approved by the Board of Directors. This Plan provides for the assessment of key business and corporate processes and is guided by the organizational strategy and related risks, with the objective of evaluating the adequacy, effectiveness, and efficiency of the Company's processes. The Internal Audit function independently assesses the effectiveness of governance and risk management processes, as well as the effectiveness of the internal control system, reporting any deficiencies and improvement opportunities, and recommending applicable actions. Internal Audit also monitors the implementation of corrective and preventive actions by the responsible areas, as well as their maintenance and effectiveness in mitigating risks, aiming to add value to the business and strengthen corporate governance.

**IIA May Brasil 2025 Award**

In recognition of its achievements, the Company's Internal Audit department was once again honored with the IIA May Brasil 2025 Award, granted by the Institute of Internal Auditors of Brazil (IIA Brasil).

This achievement comes in the year the department celebrates its 70th anniversary, marking its presence at the forefront of the field through investments in innovation and greater integration with audited areas, generating even more significant results for the Company.

Among the initiatives that contributed to this recognition is the Integra AI (Internal Audit) Project, created in 2024 to promote a cycle of structured conversations with business process leaders and corporate areas. The objective is to bring Internal Audit closer to other Cemig units, strengthening relationships, expanding the understanding of critical processes, and identifying improvement opportunities.

Another highlight was the team's participation in the Integrity Forum 2025, the largest Governance, Risk, and Compliance event in the country. On that occasion, Cemig presented the digital transformation of Internal Audit, with automation initiatives, intensive use of data analytics, and the achievement of the international quality certification (QA – IIA Brasil).

The IIA May Award reflects the dedication and ethical commitment of the Internal Audit team to the Company, focusing its actions on adding value to its business in the electric power sector.

**The Compliance and Anti-fraud Policy**

The Company values the prevention and combat of fraud, corruption, and any acts that may deviate from the required ethical conduct, as well as from established internal and external regulations. To this end, it relies on the commitment and diligence of its entire workforce to ensure that unlawful or unethical acts are not carried out on its behalf.

To prevent the occurrence of such acts, the Company maintains a robust system of internal controls and Compliance, which includes, among other elements, an Ethics Committee, a Whistleblower Channel, and internal policies and procedures focused on integrity, auditing, encouragement of reporting misconduct, and the prevention of fraud and corruption. All individuals engaged with Cemig—including shareholders, officers, employees, and contractors—are fully informed of these guidelines. In 2024, Cemig obtained certification under the international ISO 37001 Anti-Bribery Management System standard, reinforcing its commitment to preventing, detecting, and addressing bribery cases.

Furthermore, donations of any kind—whether direct or indirect, in cash or in goods and services, including advertising—with political purposes or that benefit political parties or their affiliates, regardless of their current activity status, are strictly prohibited. This prohibition is in accordance with the requirements of Federal Law No. 9,504/1997, known as the "Electoral Law," and its amendments introduced by Law No. 13,487 of October 6, 2017.

Cemig's Whistleblower Channel is available to both internal and external audiences, 24 hours a day, to receive reports of fraud, corruption, favoritism, moral and sexual harassment, among other irregularities that may constitute acts or omissions contrary to the law or to the principles of our Code of Conduct. The Whistleblower Channel ensures confidentiality, anonymity, and protection against retaliation for whistleblowers. The Ethics Committee is responsible for ensuring the proper investigation and handling of all reports received, and responses are made available to whistleblowers upon conclusion of the processes.

**Ethical Principles and Cemig Code of Conduct**

**Cemig Code of Conduct**

The new Cemig Code of Conduct was reviewed and revised with participation by employees of all the areas of the Company. It is based on the pillars of Cemig's identity and policies: respect for life, integrity, generation of value, commitment, innovation, sustainability, social responsibility, and alignment with the Company's cultural identity. It constitutes a pact which aims to incorporate common values, objectives and behavior, developing a of integrity. The Code is to be complied with by all the people to whom it is addressed: managers, members of the Board of Directors, members of committees under the bylaws, employees, interns and outsourced parties who have any established relationship with the Company's stakeholders.

**The Ethics Committee**

The Ethics Committee is responsible, among other attributions, for coordinating action in relation to management (interpretation, publicizing, application and updating) of the Statement of Cemig Code of Conduct, including assessment of and decision on any possible non-compliances.

The Commission is made up of 8 members including Superintendents and Managers, appointed by the Executive Board. It may be contacted through our Ethics Channel - the anonymous reporting channel on the corporate Intranet, or by email, internal or external letter or by an exclusive phone line - these means of communication are widely publicized internally to all staff. These channels enable both reports of adverse activity and also consultations. Reports may result in opening of proceedings to assess any non-compliances with Cemig's Statement of Cemig Code of Conduct.

![](image_194.jpg)

**Authorization for Economic-Financial Evaluation**

In August 2025, the Company received Official Letter SEDE/ASMERC No. 49/2025 from the State of Minas Gerais, informing that it authorized the Brazilian Development Bank (BNDES) to conduct a Request for Information (RFI). This preliminary and non-binding stage aims to identify specialized technical consultants interested in supporting the preparation of Cemig's economic-financial valuation report. The objective is to support the Company's debt amortization process within the scope of the Full Payment Program for State Debts (Propag).

**Investor Relations**

We maintain a constant and proactive flow of communication with Cemig's investor market, continually reinforcing our credibility, seeking to increase investors' interest in the Company's shares, and to ensure their satisfaction with our shares as an investment.

Our results are published through presentations transmitted via video webcast, with simultaneous translation in English, always with members of the Executive Board present, developing a relationship that is increasingly transparent and in keeping with best corporate government practices.

To serve our shareholders – who are spread over more than 40 countries – and to facilitate optimum coverage of investors, Cemig has been present in and outside Brazil at a very large number of events, including seminars, conferences, investor meetings, congresses and roadshows; as well as holding video conference calls with analysts, investors and others interested in the capital markets.

In August 2024, we held our 29rd Annual Meeting with the Capital Markets, where market professionals had the opportunity to interact with the members of the Executive Board.
