(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 profit, nor as an indicator of operational performance or cash flow, nor to measure liquidity nor the capacity for payment of debt.

(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.

(1)

The calculation of the average price does not include revenue from supply not yet billed.

(2)

Includes Regulated Market Energy Sale Contracts (CCEARs) and ‘bilateral contracts’ with other agents.

The main variations in energy supply are described below:

Residential

Residential consumption in 2Q24 was up 7.01% year-on-year, mainly on four factors:

an increase of 3.3% in the number of consumers;

II)

average monthly consumption per consumer up 3.6% YoY in the quarter, at 128.8 kWh, compared to 133.4 kWh in 2Q24;

III)

higher temperatures; and,

IV)

improvement in the economic scenario – increased energy consumption reflecting, among other factors, improved economic indicators.

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 2Q24 this revenue was R$ 1,251,554, an increase of 11.91% from 2Q23 (R$ 1,118,367).

The variation mainly reflects a 24% increase in the use of the network by Free Clients in the Commercial and services category.

Also, the volume of energy transported for clients in 2Q24 was 6.25% higher than in 2Q23.

CVA and Other financial components in tariff adjustments

In its financial statements Cemig D recognizes the positive or negative differences between its actual non-manageable costs in the period and the estimated values for these costs that were used as the basis for setting tariffs. The result is a balance that must either be reimbursed to the consumer or credited to Cemig D by inclusion in its next tariff adjustment.

In the second quarter of 2024, this amount was a gain of R$56,556, which compares to a gain of R$164,649 in 2Q23. The difference mainly reflects higher totals for (i) charges for use of the national grid, and (ii) energy purchased for resale.

For more details please see Note 11.3 to this Interim Accounting Information.

Reimbursement, paid to consumers, of credits of PIS/Pasep and Cofins taxes - Amount realized

For 2Q24 the Company posted a positive item (gain) of R$190,186 under Realization of restitution to consumers of credits of PIS, Pasep and Cofins taxes, which compares with of R$561,518 in 2Q23. This recomposition of revenue is due to Cemig D considering the discount on the amounts being returned to consumers relating to PIS/PASEP and COFINS credits.

Distribution Construction Revenue

The Construction revenue, associated with construction of infrastructure for the distribution concession in 2Q24, totaled R$1,154,213 – 26.03% higher than in 2Q23 (R$915,822). This basically reflects the higher number and volume of works being undertaken, mainly in distribution networks, under Cemig’s Distribution Development Plan (PDD).

This revenue is fully offset by Construction costs, of the same amount, and corresponds to the investments by Cemig D in assets of the concession in the year.

Transmission concession revenue

The main variations in components are:

The component for construction, strengthening and enhancement of infrastructure in 2Q24 was R$104,891 – an increase of 50.27% compared to R$69,802 in 2Q23. The higher value mainly reflects the stage of development of projects – in this period a significant volume of primary equipment that has high financial value was supplied.

Revenue from financial remuneration on transmission contract assets was 25.07% higher in 2Q24, at R$134,430, compared to R$107,485 in 2Q23. This variation is mainly associated with the IPCA inflation index (base for the remuneration of contracts), which was 1.05% (positive) in 2Q24, compared to 0.76% in 2Q23.

Taxes and regulatory charges reported as deductions from revenue

Taxes and charges on revenue in 2Q24 totaled R$3,427,961, compared to R$3,231,998 in 2Q23 – a year-on-year increase of 6.06%, mainly reflecting the higher revenue in the quarter.

Costs and expenses

Operational costs and expenses in 2Q24 were R$7,441,898, compared to R$7,313,127 in 2Q23.

The main variations in components of this total are as described below; and there is more information on the breakdown of Operational costs and expenses in Note 25 to this quarterly information.

This text is a translation, provided for information only. The original text in Portuguese is the legally valid version.

Energy bought for resale

The cost of energy purchased for resale in 2Q24 was R$3,693,227, which compares to R$3,468,393 in 2Q23. The main factors here were:

The cost of energy acquired in Regulated Market auctions was higher, at R$1,035,152 in 2Q24, compared to R$980,749 in 2Q23 – reflecting (i) the annual adjustments to contracts, by the IPCA inflation index, and (ii) entry of new contracts.

The cost of supply from distributed generation was R$697,974 in 2Q24, compared to R$491,669 in 2Q23. This higher figure reflects (i) the higher number of generation units installed (273,174 at the end of 2Q24, compared to 230,686 at the end of 2Q23); and (ii) the higher volume of energy injected into the grid (1,487 GWh in 2Q24, compared to 1,119 GWh in 2Q23).

Costs of physical quota guarantee contracts in 2Q24 totaled R$214,415, compared to R$228,692 in 2Q23 – mainly reflecting (i) seasonal effects in allocation of energy by Aneel, and (ii) reduction of quota contracts due to the process of privatization of Eletrobras.

Charges for use of the national grid, and other system charges

Charges for use of the electricity system, net of the credits of PIS, Pasep and Cofins taxes, totaled R$817,136 in 2Q24, compared to R$704,850 in 2Q23, a year-on-year increase of 15.93%.

This expense refers to the charges paid by electricity distribution and generation agents for use of the facilities and components of the national grid and the electricity system. The amounts to be paid by the Company are set by an Aneel resolution.

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, for reasons of supply; and (iii) a lower volume of wind generation.

Av. Barbacena, 1200 – Santo Agostinho – 30190-131 Belo Horizonte, MG – Brazil – Fax (+55-31) 3506-5026 – Tel.: (+55-31) 3506-5024

This text is a translation, provided for information only. The original text in Portuguese is the legally valid version.

This is a non-manageable cost: the difference between the amounts used as a reference for setting of tariffs and the costs actually incurred is compensated for in the subsequent tariff adjustment.

Employee and management profit-sharing

The impact of the Company’s post-retirement obligations on 2Q24 net profit was an expense of R$98,391, which compares with R$157,841 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.

Outsourced services

The expense on outsourced services in 2Q24 was R$507,705, 11.12% higher than in 2Q23 (R$456,909). The main factors in the higher figure are:

Expenses on maintenance and conservation of electrical facilities and equipment 13.67% higher, at R$189,004 in 2Q24, compared to R$166,280 in 2Q23. This mainly reflects an increase in the total value of the services contracted, and a higher number of emergency service calls carried out.

Expenses on cleaning of power line pathways 37.48% higher in 2Q24, at R$38,292, compared to R$27,852 in 2Q23, mainly reflecting a higher volume of services carried out in 2024.

Provisions for contingencies

The Company posted a net reversal of provisions for contingencies in 2Q24 of R$454,184, which compares with new provisions made of R$100,152 in 2Q23.

The main difference is in provisions for tax contingencies, in which there was a reversal of R$578,740 in 2Q24, compared to new net provisions of R$33,844 in 2Q23. The reversal was the result of the Company winning a court judgment which extinguished a demand for payment of social security contributions on profit shares paid to employees.

Provisions for client default

Provisions for losses resulting from client default totaled R$77,300 in 2Q24, compared to R$21,266 in 2Q23. This reflects the alteration, in August 2022, of the time limit for full recognition of unpaid receivables from 12 to 24 months, to give a more precise estimate of losses expected on overdue client bills.

Net finance revenue (expense)

The company posted net financial revenue of R$118,119 in 2Q24, which compares to net financial revenue reported for 2Q23, of R$39,810. The higher figure is mainly associated with the following factors:

Updating of taxes to be returned to consumers

The monetary updating of the tax credits created by the court judgment on PIS, Pasep, and Cofins taxes (in which amounts of ICMS tax were excluded from the basis for calculation of these taxes), and the related liability for reimbursement of these credits to consumers, is presented at net value.

A net financial revenue item of R$406,414 was recognized in 2Q24, compared to a financial expense item of R$16,779 in 2Q23.

This reflects a write-down, in May 2024, of R$410,626 in the liability posted as ‘Amounts to be repaid to consumers”, recognized in Finance income – 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. For more details please see Note 18.

FX variation on loans

In 2Q24 the US dollar appreciated by 11.26% against the Real, in contrast to 2Q23, when the dollar depreciated by 5.14% against the Real. This generated a negative (financial expense) item for FX variation on loans in 2Q24, of R$273,485, compared to a positive (financial revenue) item in 2Q23, of R$301,310.

This text is a translation, provided for information only. The original text in Portuguese is the legally valid version.

Derivative financial instrument

As a result of the yield curve rising in relation to the expectation of growth in the dollar exchange rate against the Real, the fair value of the financial instrument contracted to hedge the Eurobonds posted a gain of R$70,018 in 2Q24, compared to a loss of R$150,010 in 2Q23.

For the breakdown of Financial revenues and expenses please see Note 26.

Results by segment

The results presented separately by segment do not take into account eliminations of inter-segment transactions – which are made in the consolidated result.

Distribution segment performance

For 2Q24 Cemig’s electricity distribution operations posted profit of R$ 1,060,437, compared to R$ 365,437 in 2Q23.

Net revenue

Net revenue in the distribution segment in 2Q24, at R$6,326,844, was up 14.01% from R$5,549,457 in 2Q23. The following are the main variations in components:

revenue from supply of electricity was R$5,881,556 in 2Q24, up 15.37% from 2Q23 (R$5,097,880). The increase in energy supply to residential customers is mainly due to four factors: (i) increase in the number of consumers; (ii) increase in average monthly consumption per consumer; (iii) higher temperatures, and (iv) improvement in the economic scenario;

the Company posted an adjustment to revenue, reflecting realization of reimbursement to consumers of credits of PIS, Pasep and Cofins taxes, in the amount of R$190,186, in 2Q24, compared to R$561,518 in 2Q23. This recomposition of revenue is due to Cemig D considering the discount on the amounts being returned to consumers relating to PIS/PASEP and COFINS credits;

revenue for use of the network, charged to Free Clients as the TUSD (Tariff for Use of the Distribution System – Tarifa de Uso do Sistema de Distribuição) on the volume of energy distributed. In 2Q24 this revenue was R$1,261,441, or 12.06% higher than in 2Q23 (R$1,125,668);

taxes and charges on revenue in 2Q24 totaled R$2,723,111, compared to R$2,502,738 in 2Q23. This increase mainly reflects the higher revenue.

Costs and expenses

Operational costs and expenses in 2Q24 were R$5,221,702, or 3.24% higher than in 2Q23 (R$5,058,009).

Cost of electricity

In 2Q24 the cost of electricity was R$3,394,674, an increase of 11.72% compared to R$3,038,649 in 2Q23. The main factors are:

the cost of electricity purchased for resale in 2Q24, at R$2,544,751, was 10.35% higher than in 2Q23 (R$2,306,032);

charges for use of the electricity system, net of the credits of PIS, Pasep and Cofins taxes, were 16.01% higher, at R$849,924 in 2Q24, compared to R$732,617 in 2Q23.

Operational provisions

The Operational provisions line in 2Q24 was a reversal of R$378,912, compared to net new provisions in 2Q23 of R$105,643. The main factors in the difference:

a reversal, of R$512, 774 in provisions for tax contingencies, compared to constitution of net new provisions totaling R$24,827 in 2Q23. This mainly reflects the judgment won in the courts by the Company, canceling a demand for payment of social security contributions on profit shares paid to employees and executives;

higher net new provisions for client default were made in 2Q24: R$72,447, compared to R$21,334 in 2Q23. This arises from the alteration, in August 2022, of the time limit for full recognition of unpaid receivables from 12 to 24 months, to give a more precise reflection of actual estimates of losses expected on overdue client bills. This change had effects over a period of 12 months, including the second quarter of 2023;

provisions for employment-law contingencies were 137.78% higher year-on-year: net new provisions of R$36,808 were made in 2Q24, compared to net new provisions of R$15,480 made in 2Q23. This mainly arises from ongoing proceedings in collective employment-law actions, in which the calculations for provisions made by expert witnesses were revised;

net new provisions for third-party contingencies were 55.50% lower year-on-year, at R$11,832 in 2Q24, compared to R$26,586 in 2Q23. This is mainly the result of court judgments relating to claims of third-party liability given in favor of the company.

There is detailed information on the variations and effects presented in this segment in the interim financial statements of Cemig D.

Transmission – Results

The transmission segment posted net profit of R$108,947 in 2Q24, compared to R$99,390 in 2Q23.

Transmission concession revenue

The main variations in components are:

the component for construction, strengthening and enhancement of infrastructure in 2Q24 was R$104,891 – an increase of 50.27% compared to R$69,802 in 2Q23. The higher value mainly reflects the stage of development of projects – this was a period of significant supply of primary equipment, which has high financial value;

revenue from financial remuneration on transmission contract assets was 25.07% higher in 2Q24, at R$134,430, compared to R$107,485 in 2Q23. This variation is mainly associated with the IPCA inflation index (base for the remuneration of contracts), which was 11.26% (positive) in 2Q24, but negative (i.e. there was deflation) at 5.14% in 2Q23.

Finance income (expenses)

In 2Q24 the transmission segment posted net financial expenses of R$41,764, compared to R$1,359 in 2Q23. The difference is mainly due to the effect of exchange rate variation on loans.

Detailed information on the variations and effects presented in this segment can be found in the interim financial statements of Cemig GT.

Generation – Results

For the second quarter of 2024 Cemig’s generation segment posted profit of R$315,039, or 13.14% lower than in 2Q23 (R$362,695).

The variation mainly comes from the higher effect of exchange rate variation, resulting in posting of net financial expenses of R$79,729 in 2Q24, compared to net financial revenue of R$10,055 in 2Q23.

Detailed information on the variations and effects presented in this segment can be found in the interim financial statements of Cemig GT.

Trading – Results

For 2Q24 the aggregate results of Cemig’s Power Trading activity posted profit of R$101,008, compared to R$213,386 in 2Q23.

Net revenue

Net revenue of Cemig’s Trading segment in 2Q24 was R$1,658,117, 13.13% lower than in 2Q23 (R$1,908,694), mainly reflecting changes in the portfolio of contracts, with contracts with higher selling prices terminating and being replaced by contracts at lower prices, reducing average selling price.

Costs and expenses

Cost of electricity

The total cost of electricity in 2Q24 was R$1,468,942, 7.50% less than in 2Q23 (R$1,588,122). This mainly reflects change in the portfolio of contracts, with termination of contracts with higher selling prices and their replacement by contracts at lower prices, reducing average purchase price.

Provisions for contingencies

The probability of loss was re-evaluated from possible to probable in the ordinary lawsuit against the Company, which requires the declaration of the nullity of a clause in the purchase and sale of electricity on the free market, as well as the refund of the amounts paid by the plaintiff. In addition, the request to reduce the amount of the rescission fine and to exclude the incidence of the spread in the calculation of the debt was partially granted. The total amount provisioned in June 2024 is R$52,647.

Gas – Results

Retail supply of gas

Net revenue from supply of gas in 2Q24 was R$861,273, compared to R$939,421 in 2Q23 – mainly reflecting lower volume of gas sold in 2024, in turn mainly due to lower exports by industries, especially in the metallurgical sector.

Gas purchased for resale

Due to lower need for purchase of gas for resale, and a lower unit cost of gas, the total cost of gas purchased for resale in 2Q24 was lower, at R$508,828,than in 2Q23 (R$572,442).

Equity interests, and the holding company

For 2Q24 the aggregate result of Cemig’s equity interests and holding company was a net loss of R$34,668, which compares with net profit of R$41,892 in 2Q23.

In March 2024 Cemig GT’s equity interest in Aliança Geração was classified as a non-current asset held for sale, and its results ceased to be recognized through equity income as from April 2024.

2.3

Reclassification of items in the Cash Flow Statements (CFS)

During the process of preparing and reviewing the financial statements, the Company's management identified opportunities to improve the disclosure of some specific transactions.

The presentation of the movement in the Securities item was disclosed on a net basis, in the flow of investment activities. As of the fourth quarter of 2023, the Company and its subsidiaries have segregated this movement, presenting the interest actually received as part of the cash flow from operating activities and the investments and redemptions separately in the cash flow from investing activities. In addition, the Company and its subsidiaries began to adjust profit with the total amount of income tax recognized in profit or loss.

In order to maintain comparability, the information corresponding to the first half of 2023 is being presented using the same criteria.

3. PRINCIPLES OF CONSOLIDATION

The reporting dates of financial information of the subsidiaries used for the purposes of calculation of consolidation and jointly controlled entities and affiliates used for calculation of this equity method contribution are prepared as of the same reporting date of the Company. Accounting policies are applied uniformly in line with those used by the parent company.

The direct equity investments of Cemig, included in the consolidation, are the following:

Subsidiary	June 30, 2024 and December 31, 2023
Subsidiary	Form of valuation	Direct interest, %
Cemig Geração e Transmissão S.A. (“Cemig GT”)	Consolidation	100.00
Cemig Distribuição S.A. (“Cemig D”)	Consolidation	100.00
Companhia de Gás de Minas Gerais (“Gasmig”)	Consolidation	99.57
Cemig Soluções Inteligentes em Energia S.A. (“Cemig Sim”)	Consolidation	100.00
Sete Lagoas Transmissora de Energia S.A. (“Sete Lagoas”)	Consolidation	100.00

4. OPERATING SEGMENTS

Detailed information on the operating segments is in Note 5 to the financial statements for 2023, with the exception of the points set out below on the gas segment being shown separately. This information was included under Equity interests.

From the third quarter of 2023, due to a change in the way in which the principal manager of the Group values the business segments, the Company revalued its operational segments and began to publish information on the Gas business segment separately. To maintain comparability, the information corresponding to the period of six months ended June 30, 2023 is being presented using the same criteria.

As of June 30, 2024, the Company has recorded R$30,567 in current assets (R$323,621 on December 31, 2023) and R$568,627 in non-current assets (R$582,153 on December 31, 2023), corresponding to the tax credits of PIS/Pasep and Cofins over ICMS, with updating by the Selic rate to the date of their actual offsetting.

In the period of January to June, 2024, tax credits of PIS, Pasep and Cofins taxes previously charged on amounts of ICMS tax were offset against federal taxes payable, in a total of R$25,252 (R$837,924 in the same period of 2023). Offsetting of tax credits is a transaction that does not involve cash, and thus is not reflected in the Statements of cash flow.

The Company won a legal action, against which there is no further appeal, requesting the right to deduct from corporate income tax 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$81,205 was recognized in June 2024 as Income tax recoverable, with counterpart in Income tax and in Finance revenue (expenses).

For residential consumers connected at low voltage, the average increase was 6.70%.

Voltage level	Average effect for the consumer
High and medium voltage – Group A	8.63%
Low voltage – Group B	6.72%
Average increase	7.32%

This result reflects: (i) upward adjustment in the cost items of Portions A and B, calculated as specified by the Tariff Regulation Procedures, PRORET), for the formation of the revenue applied for; (ii) inclusion of the financial components calculated in the current tariff adjustment for offsetting over the subsequent 12 months; and (iii) withdrawal of the financial components established in the previous tariff process, which were in force until the date of the current adjustment.

This refers to the reversal of provisions recorded in previous years for losses recorded on assets in progress (canceled work). The reversal was necessary because some of the work was resumed and completed.

The amount of additions in the period from January to June, 2024 includes R$35,260 (R$29,861 in the same period of 2023) borrowing costs, as presented in note 19. The average rate to determine the amount of borrowing costs was 11.26%. The nature of the additions to contract and intangible assets is shown in note 25b.

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

Financial expenses recognized in the Statement of income are net of incorporation of the credits for PIS/Pasep and Cofins taxes on payments of rentals, in the amounts of R$778 and R$9 in the period from January to June of 2024 (R$969 and R$11 in the same period of 2023), for the consolidated and parent company interim financial information, respectively.

(2)

The Company and its subsidiaries identified events that give rise to restatement and modifications of their principal contracts; the leasing liability was remeasured with an adjustment to the asset of Right of Use.

Additions and settled in leases are non-cash transactions, and therefore are not reflected in the Statements of Cash Flows.

The potential right to recovery of PIS/Pasep and Cofins taxes embedded in the leasing consideration, according to the periods specified for payment, is as follows:

Cash flow	Consolidated		Parent company
Cash flow	Nominal	Adjusted to present value	Nominal	Adjusted to present value
Consideration for the leasing	656,340	429,056	5,173	2,845
Potential PIS/Pasep and Cofins (9.25%)	38,725	21,858	478	263

The cash flows of the leasing contracts are, in their majority, updated by the IPCA inflation index, annually. Below is an analysis of maturity of lease contracts:

	Consolidated (nominal)	Parent company (nominal)

Include the deferral on the financial remuneration of the contract asset and on the construction and improvement revenues linked to the transmission contracts.

The amounts of PIS/Pasep and Cofins to be refunded to consumers regarding the credits to be used by Cemig D and Gasmig due to the exclusion of ICMS from the calculation basis of these contributions represent the amounts of R$123,880 (R$1,014,384 on December 31, 2023) and R$153,175 (R$163,116 on December 31, 2023), respectively. The criteria for refunding Gasmig's PIS/Pasep and Cofins credits to consumers will still be the subject of discussions with the Minas Gerais Development Secretariat.

Other reversals	(9,941)
Balances on June 30, 2024	617,855

In May 2024, R$410,626 was written down from the total of ‘Amounts to be repaid to consumers’, payable to consumers as a result of the legal action, with counterpart in Finance income (expenses). That balance was being repaid to consumers through the tariff reviews. This write-down arises from 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. These criteria were only finally known at completion of the return of the amounts in the last Annual Tariff Adjustment, on May 28, 2024. The criterion adopted by Aneel to update the liability used a procedure similar to that adopted to update the ‘Other financial components” in the Tariff Adjustment calculation.
