Performance by sector

Industrial: Energy distributed to Industrial clients was 2.8% higher in 2Q24 than 2Q23, on higher physical production by industry, and was 47.2% of Cemig D’s total distribution. The greater part was energy transported for industrial Free Clients (44.9%), which was 4.2% higher by volume than in 2Q23. Energy billed to captive industrial clients was 2.3% of the total distributed, and 18.3% less in total than in 2Q23 – mainly due to migration of industrial clients to the Free Market.

Highlights by industrial sector were: (i) higher electricity consumption by Metals manufacturing (up +12.0%), Ferro-alloys (up 5.6%), Food and beverages (up 5.3%), and Cement (up 4.9%); and (ii) lower consumption in Non-ferrous metals (down 28.5%), Chemicals (down 5.8%), and Steel (down 2.7%).

Residential: Residential consumption was 25.8% of total energy distributed by Cemig D, and 7.0% higher than in 2Q23. Average monthly consumption per consumer in the quarter, at 133.4 kWh/month) was 3.6% higher than in 2Q23, reflecting temperatures higher than historic averages, and higher family consumption. Also contributing to higher consumption was the growth in the number of clients in this category – an increase of +3.3% (+253,100 clients).

COMPANHIA ENERGÉTICA DE MINAS GERAIS S.A. | 10 |

Index

Commercial and services: Energy distributed to these consumers was 13.3% of the total distributed by Cemig D in 2Q24, and by volume 3.6% more than in 2Q23. This increase is the result of a 5.8% reduction in energy billed to captive clients, and an increase of 25.9% in the volume of energy transported for Free Clients. The increase in consumption is related to expansion of the services sector, growth of retail sales, and the effect of temperatures above historical averages in the period. It is worth noting that the increase in this user category happened in spite of the migration of consumers to Distributed Generation, which, along with migration to the Free Market, was reducing captive consumption.

Rural: Consumption by rural clients was 6.3% of the total energy distributed, and 4.7% lower by volume than in 2Q23, mainly due to a reduction of 8.6% in the number of consumer units in this category.

Public services consumed 6.8% of the energy distributed in 2Q24, in total 4.0% lower by volume than in 2Q23.

The Annual Tariff Adjustment

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

On May 14, 2024 Aneel ratified Cemig D’s Tariff Adjustment to be effective from May 28, 2024 to May 27, 2025, the result of which was an average increase for consumers of 7.32%. The average effect for low-voltage clients was an increase of 6.72%, and for residential consumers an increase of 6.70%. The percentage component corresponding to manageable costs (referred to as ‘Portion B’) was 1.27%. The increase relating to non-manageable costs (‘Portion A’ – comprising purchase of energy, transmission, sector charges and non-recoverable revenues) was 0.81%; and the increase in the financial components of the tariff contributed 5.23%. The financial components effect in 2024 comes mainly from removal of the component included in the 2023 adjustment process relating to the repayment to consumers of PIS, Pasep and Cofins taxes totaling R$ 1.27 billion.

Supply quality indicators – DEC and FEC

In 2023 the State of Minas Gerais experienced an increase in extreme atmospheric events, which caused a slight increase in electricity outages. Cemig has taken initiatives to reduce the number and duration of outages, making major investments in the distribution business to provide a quality service to clients.

These actions are already generating positive results. The DEC indicator (average outage Duration per Consumer) was again within the regulatory limit: in the 12-month window to the end of June 2024 Cemig’s DEC was 9.19 hours, compared to the regulatory target of 9.64 hours.

Combating default

The Company has kept its collection activity at a high level, keeping its Receivables Recovery Index high: in June 2024 it was 98.21%.

New payment channels, and online negotiation, have helped to increase the proportion of collection via digital channels (PIX instant payments, automatic debits, payments by card, app, etc.). This percentage reached 67.71% of the total collected in 2Q24, compared to 59.62% in 2Q23. A highlight is the PIX system, which was used for 26.2% of all collections. This system has saved R$ 25 million since it was implemented. The change in the collection mix has reduced costs by 21% compared to June 2023.

Energy losses

In the 12 months to the end of June 2024 energy losses, at 10.91%, were above the regulatory target (10.66%).

Highlights in our combat of energy losses in the period to June 2024 include: 185,000 inspections; replacement of more than 336,000 obsolete meters; replacement of 57,000 conventional meters by smart meters (bringing the total of smart meters installed since the project began in September 2021 to 400,000); and regularization of 6,900 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 by the program since it began in February 2023 to 17,093. Planned for full-year 2024 are: 350,000 inspections; installation of a further 200,000 smart meters; and regularization for 30,000 families in low-income communities.

Cemig GT and Cemig Holding Company

Electricity market

The total volume of electricity sold by Cemig GT and the holding company (‘Cemig H’), excluding sales on the wholesale power exchange (CCEE) was 2.5% less than in 2Q23. Cemig GT billed 4,845 GWh (including quota sales) in 2Q24, 24.3% less than in 2Q23.

The lower figure is the result of transfer of sales contracts to Cemig H, which reported sales of 4,714 GWh in 2Q24, 38.5% more than in 2Q23. The migration of purchase contracts from Cemig GT to the holding company began in 3Q21, and has been gradually increasing since then. Approximately 60% of these contracts have now been transferred.

Volume of gas sold in 1H24 was 8.0% lower than in 1H23, and volume distributed to industrial Free Clients was 9.0% higher.

Gasmig’s Ebitda was 7.1% lower in 2Q24 than 2Q23, reflecting the lower volume of gas sold, and also the lower compensatory component included in the tariff (for differences between actual costs and cost included in the tariff award calculation). In 2Q23 there was a positive effect on profit from receipt of R$ 24 million in these compensatory payments.

Gasmig’s number of clients increased by 13.1% from 1H23, to a total of 100,482 consumers in June 2024. This growth reflects expansion of both the commercial and the residential client bases (addition of 11,700 clients).

Energy sold to final consumers

Gross revenue from sales to final consumers in 2Q24 was R$ 7,210.1 million, which compares with R$ 6,576.77 million in 2Q23, a year-on-year increase of 9.6%, in spite of the total volume of energy sold to final consumers being 0.7% lower. The difference mainly reflects a lower total of credits of PIS, Pasep and Cofins taxes being reimbursed to consumers in 2Q24: R$ 190 million, compared to R$ 562 million in 2Q23.

Wholesale supply

Revenue from wholesale supply in 2Q24 was R$ 933.9 million, compared to R$ 951.9 million in 2Q23 – reflecting volume sold 4.5% lower year-on-year.

Transmission

Financial remuneration of transmission contractual assets | 134,430 | 107,485 | 25.1%
Total | 319,037 | 273,051 | 16.8%

Revenue from financial remuneration of transmission contractual assets was 25.1% higher, at R$ 26.9 million, in 2Q24, mainly due to the IPCA inflation index, the basis for remuneration of the contract, being higher: +1.05% in 2Q24, compared to +0.76% in 2Q23. Construction revenue was 50.3% higher, at R$ 35.1 million, mainly due to the stage of the construction projects to enhance strengthen the Company’s networks: this phase involves significant supply of primary equipment, with high financial value. In counterpart, operation and maintenance revenue was 16.8% lower.

Gas

Gross revenue from supply of gas in 2Q24 was R$ 972.4 million, compared to R$ 1,073.6 million in 2Q23. This reflects lower volume sold to the industrial and automotive segments in 2Q24, and also a lower ‘compensation component’ being awarded in the tariff in 2024. In 2Q23 there was a contribution to revenue of R$ 24 million in these compensatory components.

The consolidated expense on electricity bought for resale in 2Q24 was R$ 3.69 billion, an increase of R$ 224.8 million (6.5%) from 2Q23. Main factors are:

| § | Expenses on energy acquired in the Regulated Market were R$ 54.4 million higher (+5.5%) than in 2Q23, reflecting (i) the annual adjustments to contracts, by the IPCA inflation index, and (ii) entry of new contracts.

| § | The expense on distributed generation was R$ 206.3 million higher (+42.0%), reflecting the increase in the number of generation units (to 273,000 in June 2024, from 231,000 in June 2023), and a 32.9% YoY increase in the volume of energy injected, to 1,487 GWh in 2Q24.

| § | The costs of energy acquired in the Free Market (the Company’s highest cost of purchased energy) totaled R$ 1,270 million, an increase of R$ 4.5 million (+0.4%) in relation to 2Q23.

| § | Costs of physical quota guarantee contracts in 2Q24 totaled R$ 214.4 million, compared to R$ 228.7 million in 2Q23. This reduction mainly reflects (i) seasonal effects in allocation of energy by Aneel, and (ii) reduction of quota contracts due to the process of privatization of Eletrobras.

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 2Q24 totaled R$ 817.14 million, 15.9% higher than in 2Q23. The difference primarily reflects (i) entry into operation of Reserve Energy contracts under the Simplified Competitive Procedure (PCS) of 2021, with a consequent increase in the reserve energy charges in the period; (ii) dispatching of thermal plants, due to supply factors; and (iii) a lower volume of wind generation.

This is a non-manageable cost in the distribution business: 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 2Q24 was R$ 508.83 million, or 11.1% less than in 2Q23. This reflects both (i) a lower price of gas acquired for resale, and also (ii) lower quantity: total volume sold was 8.0% lower year-on-year.

Outsourced services

Expenditure on outsourced services was 11.1% (R$ 50.8 million) higher than in 2Q23, the main factors being: (i) the expense on maintenance of electrical facilities and equipment was higher by R$ 22.7 million (+13.7%); (ii) the expense on cleaning of power line pathways was R$ 10.4 million higher (+37.5%); and (iii) the expense on tree pruning was R$ 8.0 million higher (+63.3%).

Provisions for client default

The expense on provisions for losses due to client default in 2Q24 was R$ 77.3 million, compared to R$ 21.3 million in 2Q23. The low figure in 2023 mainly reflects the revision, in 3Q22, of the criteria for accounting for overdue client receivables, which had a positive effect over 12 months: in that revision, the threshold for posting 100% loss was increased from 12 to 24 months, so as to more faithfully reflect the behavior of Cemig’s clients in practice.

Provisions

The provisions in 2Q24 was a reversal of R$ 429.6 million – which compares to posting of new provisions totaling R$ 132.5 million in 2Q23. This mainly reflects the judgment won in the courts by the Company, in the first instance, canceling the charge of social security contributions on Profit Sharing. As a result, provisions previously made for that action, totaling R$ 584.4 million, were reversed.

Also in the quarter, a provision of R$ 52.6 million was made for a civil action against Cemig GT, due to reassessment of the probability of loss from possible to probable, which called for annulment of a purchase clause in a Free Market trading contract and repayment of the amounts the plaintiff had paid. In addition, the judgment to reduce the amount of the termination fine and to remove the incidence of spread in the calculation of the debt was partially granted.

Post-employment liabilities

The impact of the Company’s post-retirement obligations on operational profit in 2Q24 was an expense of R$ 98.4 million, compared to an expense of R$ 157.8 million in 2Q23. The difference is mainly due to reduction in the number of participants in the Integrated Health Plan (Plano de Saúde Integrado – PSI) due to active employees voluntarily subscribing to the new health plan, called the Premium Plan, offered by the Company.

People

Personnel expenses were R$ 416.8 million in 2Q24, compared to R$ 321.2 million in 2Q23. In May 2024 Cemig approved the 2024 Voluntary Retirement Program, which was joined by 357 employees. The expense on the program totaled R$ 78.1 million, recognized in Personnel costs.

Net finance income (expenses) | 118,119 | 39,810 | 196.7%

For 2Q24 the Company posed consolidated net financial revenue, of R$ 118.1 million, compared to net financial revenue of R$ 39.8 million in 2Q23. Components:

| § | The main factor is a write-down, in May 2024, recognized in Finance income, of R$ 410.6 million in the liability posted as “Amounts to be repaid to consumers” – due to the estimated amount of financial updating that had been posted by Cemig D for this liability being higher than under the criterion finally used by Aneel.

| § | The Company won a legal action requesting the right to deduct from income tax the costs and expenses incurred on the Workers’ Food Program (PAT), up to a limit of 4% of tax payable, without being subject to limitations set by certain regulations in force at the time. The Company also requested recognition of the right to be reimbursed amounts paid in excess in the years 2004-2008, with monetary updating by the Selic rate. As a result of the judgment, a recoverable total of R$ 81.2 million was recognized in June 2024: R$ 50.2 million in Finance revenue, and credit of R$31 million in the income tax result.

| § | Income from cash investments, at R$ 117 million in 2Q24, R$ 11 million higher than in 2Q23 – mainly reflecting a higher volume of cash available for investment in 2024.

Index

| § | Monetary updating on the balances of CVA and Other financial components in tariff increases: an expense of R$ 2.7 million in 2Q24, compared to a gain (revenue) of R$ 65.5 million in 2Q23. This basically reflects the monetary updating of the Financial component “Bandeira Escassez Hídrica” approved by Aneel in the 2023 tariff process, with financial revenue recorded in 2Q23.

| § | In 2Q24 the US dollar appreciated by 11.26% against the Real, compared to a depreciation of 5.14% in 2Q23, generating an expense of R$ 214.5 million in 2Q24, compared to a gain of R$ 197.5 million in 2Q23.

| § | The fair value of the financial instrument contracted to hedge the risks connected with the Eurobonds gained R$ 70 million in value in 2Q24; and lost value of R$ 150 million in 2Q23.

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 financial revenue (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. In accordance with CVM Instruction 156/2022, the Company adjusts Ebitda to exclude extraordinary items which, by their nature, do not contribute to information on the potential for gross cash flow generation.
