~~Net~~Vice ~~finance~~President ~~revenue~~of ~~(expense)~~Finance and Investor Relations

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.

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.

Income tax and social contribution

In 2Q24 the Company posted an expense on income tax and the Social Contribution tax of R$462,337, on pre-tax profit of R$2,150,923 – an effective rate of 21.49%. In 2Q23 the income tax expense was R$370,099, on pre-tax profit of R$1,615,481 (an effective rate of 22.91%).

The effective rates are reconciled with the nominal rates in Note 9d.

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.

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.

The Annual Tariff Adjustment

On May 10, 2024 Aneel ratified the result of the Annual Tariff Adjustment of Cemig D (Distribution), to be in effect up to May 27, 2025, with average effect perceived by consumers of 7.32% – its components included average increases of: 8.63% for high-voltage consumers, and 6.72% for consumers connected at low voltage. 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.

In the composition of the average effect: (i) the variation of the costs of Portion A contributed 0.81%; and (ii) the update of Portion B was responsible for 1.27%, reflecting, among other factors, the accumulated variation of the IPCA inflation index, of 3.69% in the period from May 2023 to April 2024, while (iii) the financial components accounted for the remaining 5.24%.

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.

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.

Borrowing costs, capitalized

Borrowing costs directly related to the acquisition, construction or production of an asset that necessarily requires substantial time to be completed for its intended use or sale are capitalized as part of the cost of the corresponding asset. All other borrowing costs are expensed in the period in which they are incurred. Borrowing costs comprise interest and other costs incurred by the Company related to Loans and debentures.

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

	Jan to Jun/2024	Jan to Jun/2023	Apr to Jun/2024	Apr to Jun/2023
Costs of loans and financing	494,658	505,580	258,718	250,830
Financing costs on intangible assets and contract assets (1)	(35,260)	(29,861)	(17,989)	(17,536)
Net effect in income or loss	459,398	475,719	240,729	233,294

(1) The average capitalization rate p.a. on June 30, 2024 was 11.26% (12.62% on June 30, 2023).

The amounts of the capitalized borrowing costs have been excluded from the statement of cash flows, in the additions 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”).

The Company and its subsidiaries have contracts with financial covenants as follows:

Title - Security	Covenant	Ratio required - Issuer	Ratio required Cemig (guarantor)	Compliance required
Eurobonds Cemig GT (1)	Net debt / Ebitda adjusted for the Covenant (3)	The following or less: 2.5	The following or less: 3.0 on/after Dec. 31, 2021	Semi-annual and annual

(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.

(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.

(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.

The information on the derivative financial instruments (swaps) contracted to hedge the debt servicing of the Eurobonds (principal, in foreign currency, plus interest), and the Company’s exposure to interest rate risks, are disclosed in Note 28.

The Company 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 interfim financial information in relation to the 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 Company 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’ result of operations or financial position.

The main provisions and contingent liabilities are disclosed in note 25 to the financial statements for the year ended December 31, 2023. For the period ended June 30, 2024, except as indicated below, there were no material changes in the progress of the proceedings or in the amounts provisioned.

Civil

Provision of electricity supply servisse

In May 2024 a class action (‘Civil Public Action” – Ação Civil Pública) was filed jointly by the State and Federal Public Attorneys, against the Company and Aneel, requiring, for the municipality of Uberlândia, adjustment of consumer electricity supply service to the standards established by the legal system; avoidance of blackouts and oscillations in supply; in-person presence in supervision of transmission and distribution of electricity; and compensation for collective pain and suffering (danos morais), in the amount of R$207,713 (on June 30, 2024). The chances of financial loss for Cemig in this action have been assessed as ‘possible’.

Relations with large consumers – Power purchasing agreement

In June 2024, the chances of financial loss were revised from ‘possible’ to ‘probable’ in an ordinary legal action against the Company calling for annulment of a purchase clause in a Free Market trading contract, with repayment of the amounts the plaintiff had paid. In addition, the application to reduce the amount of the penalty payment, and to remove the application of ‘spread’ in the calculation of the debt was granted in part. The amount of the obligation, recalculated after the decision, is R$52,647 on June 30, 2024.

Tax

Social Security contributions on profit sharing payments

In May 2024 the 4th Federal Court published a judgment in favor of the Company, on the merits, in an application to annul execution of a tax judgment relating to applicability of social security contributions to profit sharing payments. This decision determined cancellation of the tax claim and extinction of the tax execution. Due to the material scale of the amount involved in this case, the Company considered this event as legally sufficient indication for reassessing the chances of financial loss in the legal actions that have received favorable judgments at first instance from ‘probable’ to ‘possible’. This resulted in a reversal of provisions totaling R$584,350 on June 30, 2024. For the other cases related to social security contributions on profit shares, the assessments of the chance of financial loss were maintained as ‘probable’, and thus the related provisions were also maintained.

Real Estate Transmission Tax (ITBI)

The Company and its subsidiaries are parties in tax claims issued by the Municipality of Belo Horizonte for the collection of the ITBI tax on transfer of real estate properties from the holding company to its wholly-owned subsidiaries, at the moment of ‘unbundling’ of the industry. Although transfer of real estate as value to subscribe capital is exempt from tax, ITBI is being demanded on the difference between the accounting value and the ‘venal’ (officially registered) value of the real estate, based on the decision of the Federal Supreme Court, in Special Appeal (RE) No. 796,376 – Topic 796 of General Application of Precedent (Repercussão Geral). The amount of the contingency is approximately R$110,136 on June 30, 2024, and the chance of loss has been assessed as ‘possible’.

Accounts receivable from the State of Minas Gerais

The Company has a balance receivable from the State of Minas Gerais, recognized in Non-current assets, on June 30, 2024, of R$13,366 (R$13,366 on December 31, 2023), relating to return of an administrative deposit made for a dispute on the criterion for inflation correction to be applied to an advance against future capital increase (‘AFAC’), made in prior years, which was the subject of a debt recognition agreement.

On June 30, 2021, the Company retained the remaining portion of dividends to be paid to State of Minas Gerais and awaits development of the issue with CPRAC (government agency).

Regarding the discussion on the merits of the criterion used in the past for AFAC’s monetary updating, if a solution is not successfully reached either through CPRAC or any legal proceedings on the merits, Management, based on assessment of legal advisors, has assessed the chances of loss as ‘possible’. The estimated amount of the contingency on June 30, 2024 was R$277,723.

ii. R$5,207 referring to outstanding debts.

(2) 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 the actual losses expected on overdue client bills. This change had effects over 12 months, including the first half of 2023.

(1) The book value represents the approximate fair value amount, except for loans, debentures and pension fund deficit equalization in relation to the amounts as of June 30, 2024.

(2) The fair value presented is net of the transaction costs and anticipated resources presented in note 19.

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:

§ 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.

§ 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.

§ 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, 2023.

b) Financial instruments

Swap transactions, currency options and NDF

Considering that part of the loans of the Cemig GT is denominated in foreign currency, the Company uses derivative financial instruments (swaps, currency options and NDF) to protect the servicing associated with these debts (principal and interest).

The derivative financial instruments contracted by the Company have the purpose of protecting the operations against the risks arising from foreign exchange variation and are not used for speculative purposes.

The 6-monthly interest payments on the swap were paid in June 2024, resulting in a positive item of R$6,524, and cash inflow of the same amount (this compares to a negative amount of R$67,840 in the first half of 2023, with a net cash outflow of the same amount). In June 2023, a part of the hedge was undone, in the amount of US$368,890 mil, resulting in a gain of R$282,951, and net cash inflow of R$240,508.

The principal amounts of derivative transactions are not recorded in the balance sheet, as they refer to transactions that do not require the transit of full cash, but only gains or losses earned or incurred. The net results in these operations represent a positive adjustment, on June 30, 2024, in the amount of R$112,050 (negative adjustment of R$162,735 on June 30, 2023), recorded in the financial result.

The Company is the guarantor of these derivative instruments contracted by Cemig GT.

The following table shows the derivative instruments in force on June 30, 2024 and December 31, 2023:

Assets (1)	Liability	Maturity period	Trade market	Notional amount (2)	Unrealized gain / loss		Unrealized gain / loss

(1) For the US$1 billion Eurobond issued on December 2017: (i) for the principal, a call spread was contracted, with floor at R$3.25/US$ and ceiling at R$5.00/US$; and (ii) a swap was contracted for the total interest, for a coupon of 9.25% p.a. at an average rate equivalent to 150.49% of the CDI. For the additional US$500 issuance of the same Eurobond issued on July 2018 a call spread was contracted for the principal, with floor at R$3.85/US$ and ceiling at R$5.00/US$, and a swap was contracted for the interest, resulting in a coupon of 9.25% p.a., with an average rate equivalent to 125.52% of the CDI rate. The upper limit for the exchange rate in the hedge instrument contracted by the Company for the principal of the Eurobonds is R$5.00/US$. The instrument matures in December 2024. If the USD/BRL exchange rate is still over R$5.00 in December 2024, the company will disburse, on that date, the difference between the upper limit of the protection range and the spot dollar on that date. The Company is monitoring the possible risks and impacts associated with the dollar being valued above R$5.00 and assessing various strategies for mitigating the foreign exchange risk up to the maturity date of the transaction. The hedge instrument fully protects the payment of six-monthly interest, independently of the USD/BRL exchange rate. This does not, however, protect the amount of Income tax withheld at source (Imposto de Renda Retida na Fonte - IRRF) on the payment of interest.

(2) In thousands of US$.

In accordance with market practice, the Cemig GT uses a mark-to-market method to measure its derivatives financial instruments for its Eurobonds. The principal indicators for measuring the fair value of the swap are the B3 future market curves for the DI rate and the dollar. The Black & Scholes model is used to price the call spread, and one of parameters of which is the volatility of the dollar, measured on the basis of its historic record over 2 years.

The fair value on June 30, 2024 was R$486,625 (R$368,051 on December 31, 2023), which would be the reference if Cemig GT would liquidate the financial instrument on June 30, 2024, but the swap contracts protect the Company’s cash flow up to the maturity of the bonds in 2024 and they have carrying amount of R$512,376 on June 30, 2024 (R$445,115 on December 31, 2023).

Cemig GT is exposed to market risk due to having contracted this hedge, the principal potential impact being a change in future interest rates and/or the future exchange rates. Based on the futures curves for interest rates and dollar, the Cemig GT estimates that in a probable scenario, in December 2024, its results would be positively affected by the swap and call spread, in the amount of R$102,242. The fair value of the financial instrument was estimated in R$410,084, with a positive amount of R$418,526 refers to the option (call spread) and a negative amount of R$8,442 refers to the swap.

Based on the base scenario observed on June 30, 2024, the Cemig GT measured the effects on its net income of the ‘probable’ and ‘adverse’ scenarios, in which the projections for interest rates and the US dollar exchange rate are high, simulating a scenario of economic stress.

The results are shown below:

Consolidated	Base scenario June 30, 2024	‘Problable’ scenario Selic 10.50% Dólar R$5.15	‘Adverse’ scenario Selic 11.25% Dólar R$5.89
Swap, asset	1,475,478	-	-
Swap, liability	(1,483,920)	-	-
Option/ Call spread	418,526	512,326	512,326
Derivative hedge instrument	410,084	512,326	512,326

The same methods of measuring marked to market of the derivative financial instruments

described above were applied to the estimation of fair value.

c) Financial risk management

Exchange rate risk

The Company and its subsidiaries are exposed to the risk of appreciation in exchange rates, with effect on loans and financing, suppliers (energy purchased from Itaipu) and cash flow.

For Cemig GT debt denominated in foreign currency, were contracted a derivative financial instrument that protects the risks associated with the interest and principal, in the form of a swap and a call spread, respectively, in accordance with the hedge policy of the Company. The Cemig GT exposures to market risk associated to this instrument is described in the topic “Swap transaction” of this Note.

The risk exposure of Cemig D is mitigated by the account for compensation of variation of parcel A items (CVA).

The net exposure to exchange rates is as follows:

Exposure to exchange rates	Jun. 30, 2024		Dec. 31, 2023
	Foreign currency	R$	Foreign currency	R$
US dollar
Loans and financing (Note 19)	(383,990)	(2,134,562)	(383,558)	(1,856,920)
Suppliers (Itaipu Binacional)	(43,096)	(239,569)	(49,528)	(239,780)
	(427,086)	(2,374,131)	(433,086)	(2,096,700)
Net liabilities exposed		(2,374,131)		(2,096,700)

Sensitivity analysis

Based on finance information from its financial consultants, the Company estimates that in a probable scenario the variation of the exchange rates of foreign currencies in relation to the Real on June 30, 2025 will be a depreciation of the dollar by 9.15% to R$5.05.

The Company has prepared a sensitivity analysis of the effects on the Company’s net income arising from depreciation of the Real exchange rate considering an adverse scenario in relation to the probable scenario.

Risk: foreign exchange rate exposure	Amount Book value	‘Probable’ scenario US$=R$5.05	‘Adverse’ scenario US$= R$5.99
US dollar
Suppliers (Itaipu Binacional)	(239,569)	(217,637)	(258,019)
Liabilities exposed	(239,569)	(217,637)	(258,019)
Effect of exchange rate fluctuation		21,932	(18,450)

Considering that the final maturity of the Eurobonds is in December 2024, the Company has made a sensitivity analysis considering an ‘adverse’ scenario in relation to the ‘probable’ scenario for December 2024.

Risk: foreign exchange rate exposure	Amount Book value	‘Probable’ scenario US$=R$5.15	‘Adverse’ scenario US$= R$5.89
US dollar
Loans (note19)	(2,134,562)	(1,977,548)	(2,261,701)
Liabilities exposed	(2,134,562)	(1,977,548)	(2,261,701)
Effect of exchange rate fluctuation		157,014	(127,139)

Company has entered into swap operations to replace the exposure to the US dollar fluctuation with exposure to fluctuation in the CDI rate, as described in more detail in the item ‘Swap Transactions’ in this Note.

Interest rate risk

The Company and its subsidiaries are exposed to the risk of decrease in Brazilian domestic interest rates on June 30, 2024. 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 loans and financings 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.

70Av. 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.

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.

This exposure occurs as a result of net assets indexed to variation in interest rates, as follows:

Risk: Exposure to domestic interest rate changes	Consolidated
	Jun. 30, 2024	Dec. 31, 2023

	(3,646,942)	(3,508,445)
Net assets exposed	928,705	227,923

Sensitivity analysis

In relation to the most significant interest rate risk, the Company and its subsidiaries estimate that in a probable scenario the Selic rate will be 10.5% and the TJLP rate will be 7.27% on June 30, 2025.

The Company and its subsidiaries made a sensitivity analysis of the effects on results considering an adverse scenario in relation to the probable scenario, as shown in the table below. The CDI rate follows the Selic rate.

Increase in Brazilian interest rates	Jun. 30, 2024	Jun. 30, 2025

Increase in inflation risk

The Company and its subsidiaries are exposed to the risk of increase in inflation index on June 30, 2024. A portion of the loans, financings and 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.

Sensitivity analysis

In relation to the most significant risk of reduction in inflation index, reflecting the consideration that the Company has more assets than liabilities indexed to inflation indexes, the Company estimates that, in a probable scenario, at June 30, 2025 the IPCA inflation index will be 4.30% and the IGPM inflation index will be 4.23%. The Company has prepared a sensitivity analysis of the effects on its net income arising from reductions in rates in an adverse scenario.

30. ASSETS CLASSIFIED AS HELD FOR SALE

Asset classified as held for sale	Jun. 30, 2024	Dec. 31, 2023
Investments - Aliança Geração (a)	1,118,565	-
Property, Plant and Equipment, Intangible Assets - Plants (b)	2,901	57,867
Financial assets – Generation – Concession grant fee (b)	35,928	-
Total	1,157,394	57,867

a) Aliança Geração

On March 27, 2024, Cemig GT approved signature of, and signed, a contract for sale of its direct 45% stake in the share capital of Aliança Geração to Vale S.A. (‘Vale’).

The Aliança Geração is made up of seven hydroelectric plants in the State of Minas Gerais, two wind complexes in operation in the State of Rio Grande do Norte and a wind complex in the final phase of implementation in the State of Ceará. Together, these assets reach 1,438 MW in installed capacity and 755 average MW of physical guarantee (information not reviewed by independent auditors).

The value of the transaction is R$2.7 billion, in currency of June 2023, to be adjusted by the CDI rate from that date up to the day before actual completion of the transaction.

In addition Cemig GT will have the right to 45% of any future indemnity compensation received by Aliança Geração relating to losses arising from events related to the failure of the Fundão tailings dam at the Risoleta Neves (Candonga) Hydroelectric Plant. The contractual amount of this indemnity is R$223 million, also updated by the CDI rate from the base date.

This sale was negotiated on the ‘closed door’ basis, exonerating Cemig GT from any indemnity related to Aliança Geração or its assets and liabilities.

In March 2024 the assets were classified as held for sale, at book value, in accordance with Item 15 of CPC 31 / IFRS 15 – with no effect on reported net profit.

Assets classified as held for sale	Book value at March 31, 2024 – R ’000	Fair value, net of sales expenses – R ’000
Aliança Geração	1,118,565	2,695,687

It was concluded that the assets classified as held for sale do not qualify within the concept of discontinued operations, under Item 32 of CPC 31 / IFRS 5, since they do not represent a significant separate line of business or geographical area of operations, nor do they constitute a subsidiary acquired exclusively for the purpose of resale.

Conclusion of sale of the equity interest in Aliança Geração

On August 13, 2024, Cemig GT concluded the sale to Vale S.A. of its directly held 45% equity interest stake in the share capital of Aliança Geração.

75Av. 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.

The total amount of the sale was R$2.74 billion, equivalent to the value of the transaction (R$2.7 billion) updated by the CDI rate from its base date of June 30, 2023, less dividends paid by Aliança Geração to Cemig GT in the period (R$299 million), at historic values.

This transaction is in line with the Company’s strategic planning, which envisages divestment of the Cemig Group’s minority stockholdings.

b) Onerous transfer of 4 PCH/UHEs

On April 1, 2024, a notice was published to hold an in-person public auction, to be conducted by B3, aiming at the onerous transfer of the right to exploit the electricity generation services of 4 PCHs/UHEs, one of which is 1 PCH from Cemig GT and 3 of its wholly owned subsidiaries, as follows:

Generation plant	Ledger	Beginning of the operation	Installed capacity (MW)¹	Physical guarantee (MWm)¹	Term	Commercial Operation Status	Site
Cemig GT
PCH Machado Mineiro	Authorization	1992	1.7	1.1	May, 2027	In operation	Minas Gerais
Cemig Geração Leste
UHE Sinceridade	Concession	1963	1.4	0.4	March, 2047	In operation	Minas Gerais
Cemig Geração Sul
UHE Marmelos	Concession	1915	4	2.7	January, 2053	In operation	Minas Gerais
Cemig Geração Oeste
UHE Martins	Concession	1950	7.7	1.8	January, 2053	In operation	Minas Gerais
Total			14.8	6.0

According to CPC 31 / IFRS 5, the classification of assets as held for sale must be carried out when starting a firm program to complete the disposal plan. The classification as held for sale was carried out in April 2024.

During the preliminary activities in preparation for the auction, the assets were assessed, which determined a minimum value of R$29.1 million for the single lot of plants. This assessment was carried out using the discounted cash flow method, considering the plants individually, and through the equity assessment of the land.

On June 27, 2024, the Company suspended the auction, due to no proposals in accordance with the public auction notice being received. The Company will reassess the project, and reaffirms its commitment to optimization of its asset portfolio, operational efficiency, and capital allocation.

The sale aims to comply with the Company's strategic planning guidelines, which advocate optimizing the asset portfolio, seeking to improve operational efficiency and better capital allocation.

31. PARLIAMENTARY COMMITTEE OF INQUIRY (‘CPI’)

On June 17, 2021, the Legislative Assembly of Minas Gerais has established a Parliamentary Committee of Inquiry (‘CPI’) to investigate management acts of Cemig since January 2019. CPI was entitled to investigate the facts underlying the application for its creation, and requested, through application, several documents and information related, mainly, human resources management and purchasing processes which were fully met by the Company within the stipulated deadlines.

On February 18, 2022 the CPI approved its final report, to be submitted to the Public Attorneys’ Office of Minas Gerais State, and other control bodies, for assessment of what further referrals of it should be made.

In August 2023, the prosecutors of the Public Attorneys’ Office of Minas Gerais decided to set aside the Public Civil Inquiries that were investigating events referred to in the CPI. The decisions stated that all acts of Cemig's management were regular. The only matter pending is conclusion of the investigation by the Minas Gerais Civil Police in relation to the IBM contract.

It should be noted that regarding processes of contracting, the Company carries out regular audits, and no material impacts have been identified in the interim financial information for the first half of 2024, nor in the financial statements of prior periods.

32. SUBSEQUENT EVENTS

Transmission – Periodic Review

Through Ratifying Resolution 3,348 of July 16, 2024, Aneel established the Annual Permitted Revenues – RAPs for the electricity transmission assets for the 2024–25 cycle, effective July 1, 2024. The Resolution set the RAPs of Cemig GT’s transmission assets in operation at R$1,243 million, an increase of 5.4% compared to the previous cycle.

Concession	Readjustment indexz	Cycle RAP 2023-2024 R$ million	Cycle RAP 2024-2025 R$ million	Change (%)
Cemig GT – 006/1997	IPCA	1,097.2	1,162	5.9
SE Itajubá 3 – 0079/2000	IGPM	43.0	43.1	0.2
Centroeste – 004/2005	IGPM	30.1	26.0	(13.6)
Sete Lagoas – 006/2011	IPCA	9.2	11.9	29.3
TOTAL		1,179.5	1,243	5.4

The increase in the RAP arises mainly from recognition in the Remuneration Base of the value of the strengthening and enhancements of the transmission assets carried out in the period.

The accounting effects arising from the RAP established for the 2024–25 cycle will be determined and recognized in the third quarter of 2024.

(A free translation of the original report in Portuguese, as filed with the Brazilian Securities Commission – CVM, prepared in accordance with the Technical Pronouncement CPC 21 (R1) – Interim Financial Reporting and the international accounting standard IAS 34 – Interim Financial Reporting, as issued by the International Accounting Standards Board – IASB)

To the Shareholders, Board of Directors and Management

Companhia Energética de Minas Gerais - CEMIG

Belo Horizonte - MG

Introduction

We have reviewed the individual and consolidated interim financial information of Companhia Energética de Minas Gerais - CEMIG ("the Company"), included in the Quarterly Information Form (ITR), for the quarter ended June 30, 2024, which comprises the statement of financial position as of June 30, 2024, and the related statements of income and comprehensive income for the three and six-months periods then ended, and the changes in shareholders’ equity and cash flows for the six-months period then ended, including the explanatory notes.

Management is responsible for the preparation of the individual and consolidated interim financial information in accordance with CPC 21(R1) and with the international standard IAS 34 - Interim Financial Reporting, issued by the International Accounting Standards Board – (IASB), such as for the presentation of this information in accordance with the standards 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 these interim financial information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and international standards on reviews 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 of making inquiries primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with the 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, nothing has come to our attention that causes us to believe that the accompanying individual and consolidated interim financial information, included in quarterly information referred to above has not been 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 standards issued by the Brazilian Securities and Exchange Commission.

Other issues - Statements of added value

The individual and consolidated interim financial information referred to above includes the individual and consolidated statements of added value (DVA) for the six-month period ended June 30, 2024, prepared under the responsibility of the Company's management and presented as supplementary information for IAS 34 purposes. These statements were submitted to review procedures carried out together with the review of the Company’s interim financial information to conclude that they are reconciled to the interim financial information and accounting records, as applicable, and its form and content are in accordance with the criteria defined in CPC 09 - Statement of Added Value. Based on our review, nothing has come to our attention that causes us to believe that those statements of value added were not prepared, in all material respects, in accordance with the criteria set forth in this Standard with respect to the individual and consolidated interim financial information taken as a whole.

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 2023, after consideration by the Audit Committee, Cemig’s updated Corporate Top Risks for 2023-24.

These risks, associated with execution of strategy and scenarios of the Company’s exposure, are under the responsibility of the members of the Executive Board, and are monitored and reported periodically to Senior Management. The Matrix includes risks from the Distribution, Generation, Transmission, Commercialization, Innovation, Information Technology, People and Corporate Services, ESG (Environmental, Social and Governance), Financial, Shareholdings and Divestment, Institutional Regulatory and Control and Integrity pillars.

To strengthen governance and discussion on risk management even further, in June 2022 the Risks Committee was created, 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 monitoring of their treatment; identification and measurement of action plans for mitigation and control of the risks identified; and assessment of the limits of tolerance to the risks to which the Company will be exposed.

In relation to responses to significant risks and any in which the tolerance limits may have been exceeded, the Company’s Internal Controls area operates an annual process of review and tests of the design of the internal controls as a whole, as laid out in the Internal Controls Matrix, to keep them compliant and updated. The Internal Controls environment has been developed and matured in recent years, as a result of efforts and investments to bring forward the evaluation calendar, automate processes, and hire and train market professionals. This has resulted in several improvements. One highlight is the removal of the Material Weakness reported in the Financial Statements for 2023 (base year 2022), which had been present from 2016 to 2021. These results now reflect a high degree of effectiveness of the internal control environment, demonstrating confidence in the Company’s risk management and its addressing of the risks related to the pillars of strategy, with a special focus on the Financial, Controls and Ethics components.

The Company also has an Annual Internal Audit Plan, approved by the Company’s management, for assessing the principal corporate procedures. The objective of this plan is to ensure appropriateness, efficacy and efficiency in the Company’s processes, as well as compliance with the laws, rules, standards and internal procedures to which the Company is subject. The Internal Audit makes an independent assessment of the efficacy of the management of risks, and the effectiveness of the internal control system, reporting any deficiencies and proposing actions for improvement to be implemented by the areas responsible, which are periodically monitored for their compliance.

IIA May Brazil 2024 Award

In recognition of its achievements in May 2024, the Company's Internal Audit was awarded the IIA May Brasil 2024 prize, granted by the Institute of Internal Auditors of Brazil.

The award reflects the commitment of Cemig's Internal Audit team to raising awareness of the importance of its activities and strengthening the partnership with the audited areas. The initiatives developed during the month of May were aimed at greater alignment with the Company's management areas on their needs and highlighting the role of auditing in assessing and improving governance processes, risk management and controls, contributing to the Company achieving its strategic objectives.

The IIA MAY 2024 award is a recognition by the Institute of Internal Auditors of Brazil for internal audits that stand out in promoting awareness and continuous improvement of their processes.

NBR ISO 31000:2018 – Risk management: compliance

Cemig has achieved a significant milestone in obtaining the Declaration of Compliance under NBR ISO 31000:2018 – Risk Management, highlighting its commitment to sound risk management practices. This international standard, focused on risk management, serves as an essential tool for improving decision-making, planning and risk management at all levels of the Company.

NBR ISO 31000:2018 recommends integration of the risk management process with decision-making, global management of the business, and the current organizational context. This means that Cemig will be able to apply the Standard’s guidelines not only in projects and operations, but also in corporate strategies, producing a comprehensive approach to identifying, assessing and mitigating risks.

To ensure compliance, Cemig's Process Management team carried out a preliminary diagnosis to assess adherence to the requirements of NBR ISO 31000:2018. Based on this diagnosis, improvements were made to the process and documentation in order to comply with the practices recommended by the standard.

Recognition of compliance with NBR ISO 31000:2018 not only validates Cemig's commitment to world-class risk management practices, but also strengthens its reputation in the market and among stakeholders. The standard helps with strategic planning and decision-making, resulting in lower loss rates and improved operational processes.

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.

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.
