Performance by sector

Industrial: Energy distributed to Industrial clients was 2.28% higher in ~~1Q24~~2Q24 than ~~1Q23~~2Q23, on higher physical production by industry, and was 4647.42% of Cemig D’s total distribution. The greater part was energy transported for industrial Free Clients (44.19%), which was 3.4.2% higher by volume than in ~~1Q23~~2Q23. Energy billed to captive industrial clients was 2.3% ~~by volume~~ of the total distributed, and 1718.63% less in total than in 2Q23 ~~1Q23~~ – mainly due to migration of industrial clients to the Free Market. Highlights of electricity consumption, by industrial sector, were: higher consumption by Mining (up +12.3%), Steel (up 8.5%), Food and beverages (up 5.5%), and Cement (up 5.0%); while consumption was lower in Chemicals (down 6.2%), and Castings (down 11.4%).

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).

~~Commercial~~COMPANHIA ~~and~~ENERGÉTICA ~~services:~~DE ~~Energy~~MINAS ~~distributed~~GERAIS ~~to these consumers was 13~~S.~~8% of the total distributed by Cemig D in 1Q24, and by volume 2~~A.8% more than in 1Q23. This increase is the result of a 3.4% reduction in energy billed to captive clients, and an increase of 16.5% 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, 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.10

~~Rural: Consumption by rural clients was 5.1% of the total energy distributed, and 16.4% higher by volume than in 1Q23, mainly due to higher consumption for irrigation, due to lower volume of rainfall.~~Index

~~Public~~Commercial and services: ~~consumed~~Energy 7distributed to these consumers was 13.03% of the ~~energy~~total distributed by Cemig D in ~~1Q24~~2Q24, and by volume 3.6% more than in ~~total~~2Q23. 2This increase is the result of a 5.8% reduction in energy billed to captive clients, and an increase of 25.9% ~~lower~~in bythe volume ~~than~~of inenergy ~~1Q23~~transported for Free Clients. ~~Total~~The ~~captive~~increase in consumption is inrelated ~~1Q24~~to ~~fell~~expansion byof ~~45.5~~the ~~GWh~~services ~~year-on-year~~sector, ~~while~~growth of retail sales, and the ~~Free~~effect ~~Market~~of ~~expanded~~temperatures byabove ~~20.3~~historical ~~GWh~~averages in the period. ~~This~~It ~~figure~~is ~~was~~worth ~~mainly~~noting ~~due~~that tothe increase in this user category happened in spite of the migration of consumers ~~migrating~~to Distributed Generation, which, along with migration to the Free Market, was reducing captive consumption.

~~The~~Rural: Consumption ~~Tariff~~by ~~Adjustment~~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 ~~Tariff~~number ~~Review~~of consumer units in this category.

OnThe ~~May 22, 2023 Aneel ratified the result of Cemig D’s 2023~~ Annual Tariff Adjustment, effective from May 28, 2023 to May 27, 2024, the result of which was an average increase for consumers of 13.27%. The average effect for low-voltage clients was an increase of 15.55%, and for residential consumers 14.91%. The percentage component corresponding to the Company’s management costs (referred to as ‘Portion B’) was 0.66%. The increase relating to non-manageable costs (‘Portion A’ – comprising purchase of energy, transmission, sector charges and non-recoverable revenues) was 5.09%; and the increase in the financial components of the tariff was 7.52%. The effect in the financial components comes mainly from absence of the R$ 2.81 billion component included in the 2022 adjustment for repayment to consumers of credits of PIS, Pasep and Cofins taxes – while repayment of R$ 1.27 billion was incorporated into the Tariff Review of 2023.

Average effects of the May 2023 Tariff Adjustment
High voltage – average	8.94%
Low voltage – average	15.55%
Average effect	13.27%

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.

~~Comparison~~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 ~~Tariff~~increase ~~Reviews~~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 ~~and~~adjustment process relating to the ~~previous~~repayment ~~cycle:~~to consumers of PIS, Pasep and Cofins taxes totaling R$ 1.27 billion.

The ~~expense~~consolidated expense on electricity bought for resale in ~~1Q24~~2Q24 was R$ 3.5169 billion, an increase of R$ 66224.68 million (16.95%) ~~higher~~from ~~than in 1Q23~~2Q23. ~~This~~Main ~~reflects,~~factors ~~mainly~~are:

§ Expenses on energy acquired in the Regulated Market were R$ 6454.24 million higher (6+5.95%) ~~higher~~ than in ~~1Q23.~~2Q23, reflecting (i) the annual adjustments to contracts, by the IPCA inflation index, and (ii) entry of new contracts.

~~Expense~~§ The expense on distributed generation was R$ 45206.03 million higher (+742.30%) ~~higher~~, reflecting the ~~higher~~increase in the number of generation ~~facilities~~units ~~installed~~ (~~261~~to 273,000 in ~~March~~June 2024, ~~compared~~from ~~to 215~~231,000 in ~~March~~June 2023), and a 4432.29% YoY increase, ~~year-on-year,~~ in the volume of energy injected, ~~that~~to ~~was~~ 1~~.438~~,487 GWh in ~~1Q24~~2Q24.

The cost of Proinfa supply was 11.6% (R$ 14.8 million) lower, mainly due to winds throughout Brazil’s Northeast being far lower than in previous periods, with an impact on wind generation by several enterprises.

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 in 1Q24 totaled R$ 843.2 million, 20.4% higher year-on-year. The difference primarily reflects: (i) a higher need for dispatching of thermoelectric generation plants in 2023, on days and intra-day periods of higher demand, due to higher temperatures; and (ii) entry into operation of the Reserve Energy contracts arising from the Simplified Competitive Procedure (Procedimento Competitivo Simplificado – PCS) of 2021, with a consequent increase in the Reserve Energy charges in the period. 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.Index

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 ~~1Q24~~2Q24 was R$ ~~510~~ 508.283 million, or 1711.01% less than in ~~1Q23~~2Q23. This isreflects ~~due~~both to (i) a lower price of gas acquired for resale, and also (ii) lower quantity: –total 9volume sold was 8.70% ~~less~~lower ~~by volume~~year-on-year.

Outsourced services

Expenditure on outsourced services was 11.01% (R$ 5150.58 million) higher than in ~~1Q23~~2Q23, the main factors being: ~~higher~~(i) the ~~expenses~~expense on: maintenance of electrical ~~installations~~ facilities and equipment (was higher by R$ 3422.17 million, ~~or 19~~(+13.47%~~, higher~~); (ii) the expense on cleaning of power line pathways (+was R$ 810.04 million, ~~or 33~~higher (+37.5%~~, higher~~); and ~~information~~(iii) the ~~technology~~expense (on tree pruning was R$ 78.20 million, orhigher 13(+63.93%~~, higher~~).

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.

Impairments

Provisions for impairment in 1Q24 totaled R$ 23.0 million: R$ 17.7 million for plants classified as held for sale, and R$ 5.3 million for a receivable from a client disputing amounts owed. In 1Q23 an impairment of R$ 46.1 million had been posted for the plants of Cemig GT which were in the process of sale (this was reversed with the success of the sale auction).

Gain on disposal of investment

With the completion of the sale of Small Hydro Plants in 1Q24, a gain of R$ 42.9 million was posted in Other costs and expenses. In 1Q23 a gain of R$ 30.5 million been posted in this line, for part of the sale of the stake in Santo Antônio.

~~CONSOLIDATED EBITDA (IFRS and Adjusted)~~Index

Ebitda is a non-accounting measure 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 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. 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.
