In 4Q23, energy supplied to captive clients plus energy transported for Free Clients and distributors totaled 12,440 GWh, or 5.0% more than in 4Q22, mainly reflecting increases in consumption by residential consumers (+388.5 GWh or +13.4%), commercial clients (+96.8 GWh or +5.9%), and rural clients (+71.4 GWh or 9.3%) - in turn reflecting higher temperatures, and a higher need for irrigation in the period.

The growth of 5.0% in total energy distributed comprises: an increase of 4.6% (+264.7 GWh) in use of the network by Free Clients, and a decrease of 5.4% (329.4 GWh) in consumption by the captive market.

Performance by sector

Industrial: Energy distributed to Industrial clients totaled 0.4% less in 2Q23 than 4Q22, on lower physical production by industry, and comprised 44.8% of Cemig D's total distribution. The greater part was energy transported for industrial Free Clients (42.3%), which was 0.9% higher in volume than in 4Q22. Energy billed to captive clients was 2.4% by volume of the total distributed, and 18.3% less in total than in 4Q22 - mainly due to migration of clients to the Free Market. Highlights of electricity consumption by industrial sector were: (i) higher consumption by Non-ferrous metals (up 17%), Paper and pulp (up 7%), Food and beverages (up 4%), and Non-metallic minerals (up 3%); while (ii) consumption was lower in Chemicals (down 12%), Metal manufacturing (down 16%), Castings (down 7%), Oil (down 19%), Pig iron (down 12%), and Textiles (down 7%).

Residential: Residential consumption was 26.4% of total energy distributed by Cemig D, and 13.4% higher than in 4Q22. Average monthly consumption per consumer in the quarter was 9.9% higher than in 4Q22, influenced by higher than historic average temperatures, increased family income, and our actions to recover losses. Also contributing to higher consumption was the growth in the number of residential clients - 3.0% in the year (an increase of 224,100).

Commercial and services: Energy distributed to these consumers was 14.0% of the total distributed by Cemig D in 4Q23, and by volume was 5.9% more than in 4Q22. This increase is the result of a 0.2% reduction in energy billed to captive clients, and an increase of 20.5% in the volume of energy transported for Free Clients. The increase in consumption is mainly the result of higher temperatures than the historic average in the period, and a better economic scenario than in 2022. It is worth noting that the increase in this user category happened in spite of the migration of consumers to distributed generation.

Rural: Consumption by rural clients was 6.7% of the total energy distributed, and 9.3% higher by volume then in 4Q22, mainly due to higher consumption for irrigation, due to scarcity of rain, and high temperatures.

Public servicesconsumed 7.4% of the energy distributed in 4Q23, a total of 5.4% higher by volume than in 4Q22. Total captive consumption in 4Q23 fell by 57.8 GWh year-on-year, while the Free Market expanded by 104.3 GWh. This was mainly due to the migration of one major client, a water and sewerage utility.

Tariff Adjustment and Review

The tariffs of Cemig D are adjusted in May of each year; and every five years there is the 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 in the Tariff Review, to provide inflation adjustment for the costs specified as manageable. Manageable costs are adjusted by the IPCA inflation index, less a deduction factor known as the 'X Factor', under a system using the price-cap regulatory model.

On May 22, 2023 Aneel ratified the result of the Annual Tariff Adjustment for Cemig D, effective from May 28, 2023 to May 27, 2024, resulting in 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 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 costs, 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 2023 tariff Review.

Average effects of the Tariff Adjustment
High voltage - average	8.94%
Low voltage - average	15.55%
Average effect	13.27%

Quality indicators - DEC and FEC

In 2023 there was an increase in extreme atmospheric events in the state of Minas Gerais, comprising longer and more intense periods of extreme heat, and also severe storms, in practically the whole of the concession area. These extreme events created extra challenges for electricity companies, especially in distribution service, causing a slight increase in power outages.

Cemig D has taken various measures to reduce the number and duration of outages in this scenario, which are already producing positive results, with the system's performance returning to appropriate levels. The limit level for DEC in 2024 is 9.64 hours.

Combating default

Cemig has maintained its high level of collection actions, achieving greater efficiency in combating default. A good indication of this is that the Receivables Recovery Index was very close to 100% in December 2023, supported by an increase of nearly 30% in use of collection tools (email, demand letters, posting on public credit records, formal protest proceedings, disconnection, and text messages).

New payment channels, and online negotiation, made available in recent quarters (PIX instant payments, automatic debits, payments by card, app, etc.) have contributed to increasing collection via digital channels - to 65.19% of the total collected. This compares with 56.50% in 4Q22, and 50.28% in 4Q21. In December 2023, 21.83% of all collection was via the PIX nationwide instant payment system (launched in 2021). This change in the collection mix reduced costs by 7.6% - a saving of R$ 5.8 million, in 2023.

Energy losses

Energy losses were compliant with the regulatory level in the 12-month period, at 10.71% (the regulatory level is 10.84%).

Highlights of our combat of losses in 2023 include 379,000 inspections, replacement of 661,000 obsolete meters, exchange of 73,000 conventional meters for smart meters (bringing the total of smart meters installed since the project began in September 2021 to 315,000), and regularization, through our Energia Legal program (a 'bulletproofed' network) of 10,000 clandestine connections by families living on occupied land and in low-income areas.

Cemig GT and Cemig Holding Company

Electricity market

The total volume of electricity sold in 4Q23 by Cemig GT and by the holding company ('Cemig H'), excluding sales on the wholesale power exchange (CCEE) was 2.7% higher than in 4Q22. Cemig GT itself sold 5,865 GWh (including quota sales) in 4Q23, 18.3% less than in 4Q22 - reflecting the transfer of electricity sale contracts to the holding company, which sold 1,593 GWh more than in 4Q22.

Sales by the holding company totaled 4,532 GWh in 4Q23, 54.2% more than in 4Q22. Migration of third-party purchase contracts from Cemig GT to the holding company began in 3Q21, and has been increasing gradually since then, having already reached approximately 62%.

Energy sold to final consumers

Gross revenue from sales to final consumers in 4Q23 was R$ 7,682.50 million, compared to R$ 5,787.70 million in 4Q22, an increase of 32.7% YoY, in spite of volume being only 3.9% higher. The increase mainly reflects the re-inclusion, in the basis for calculation of ICMS tax, of the Transmission and Distribution charges, as from Decree 45572/2023, of February 2023.

Wholesale

Revenue from wholesale supply in 4Q23 was R$ 1,234.90 million, compared to R$ 1,116.30 million in 4Q22. The increase reflects (i) updating of the amounts of the contracts, and (ii) volume sold 3.4% higher.

Transmission

	4Q23	4Q22	Change, %
TRANSMISSION REVENUE (R$ '000)
Operation and maintenance	93,755	97,144	-3.5%
Construction, strengthening and enhancement of infrastructure	92,883	137,433	-32.4%
Financial remuneration of transmission contractual assets	123,340	128,641	-4.1%
Total	309,978	363,218	-14.7%

Transmission revenue was 14.7% lower, mainly due to the construction revenue component being 32.4% (R$ 44.6 million) lower due to lower realization of investments in strengthening and enhancements in the period, reflecting new projects being at the initial stage, when disbursements are for the design and decision stages, which have lower costs. Revenue from financial remuneration of transmission contractual assets was 4.1% lower, due to the IPCA inflation index, the basis for remuneration of the contract, being lower: +1.08% in 4Q23, compared to +1.63% in 4Q22. Operation and maintenance revenue was 3.5% lower.

Gas

Gross revenue from supply of gas in 4Q23 was R$ 953.0 million, compared to R$ 1,241.50 in 4Q22. The lower figure is due to:(i) passthrough of the tariff adjustments made in the price of gas acquired in the prior 12 months (lower average prices); and (ii) the lower volume of sales to the industrial and automotive markets.

Revenue from Use of Distribution Systems - The TUSD charge

	4Q23	4Q22	Change, %

Use of the electricity distribution system	1,192,593	927,004	28.7%

In 4Q23 revenue from the TUSD - charged to Free Consumers on their distribution of energy - was 28.7% higher than in 4Q22. This reflects (i) volume of energy transported for Free Clients 4.6% higher; (ii) the average tariff for Free Clients being 1.6% higher; and (iii) re-inclusion in the basis for calculation of ICMS tax of transmission and distribution charges, as from February 2023.

Operational costs and expenses

Operational costs and expenses in 4Q23 totaled R$ 8.00 billion, which compares with R$ 8.17 billion in 4Q22. This mainly reflects (i) expenses on acquisition of gas R$ 174.6 million lower, and a gain on sale of assets of R$ 288.3 million, posted in Other expenses, in 4Q23, which compares with a gain of R$ 44.9 million in 4Q22; and (ii) on the negative side, charges for use of the national grid R$ 108.7 million higher, and construction cost R$ 72.0 million higher.

	3,957,150	3,938,967	0.5%

The expense on electricity bought for resale in 4Q23 was R$ 3.96 billion, R$ 18.2 million (0.5%) higher than in 4Q22. This arises mainly from the following factors:

§	Expenses on purchase of electricity from Itaipu were R$ 103.9 million (25.1%) lower, mainly because the price for energy from Itaipu was reduced, from U$24.73/KW to U$20.23/KW, and also because the US dollar exchange rate was 5.7% lower.

§	Expense on distributed generation R$ 108.8 million (19.4%) higher, reflecting (i) the larger number of generation facilities installed (249,000 in December 2023, compared to 191,000 in December 2022), and (ii) the 61% increase, year-on-year, in the volume of energy injected.

§	The costs of energy acquired in the Free Market, which are the Company's highest cost of purchased energy, were R$ 65.2 million (4.0%) lower than in 4Q22. Also the average purchase price was lower in 2023, due to conclusion of contracts in 2022 and start of new contracts at lower prices in 2023.

§	Expenses on energy acquired in the Regulated Market were R$ 73.2 million (7.5%) higher than in 4Q22. This reflects (i) the annual adjustments to contracts, by the IPCA inflation index, and (ii) entry of a new contracts.

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

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

Charges for use of the transmission network in 4Q23 totaled R$ 762.3 million, 16.6% 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 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.

Gas purchased for resale

The expense on acquisition of gas in 4Q23 was R$ 522.6 million, or 25.0% less than in 4Q22. This is due to a lower price of gas acquired for resale, and also lower quantity - 8.2% less by volume.

Outsourced services

Expenses on outsourced services were 2.4% lower than in 4Q22, due mainly to (i) expenses on consultancy at R$ 11.4 million, or 67.3%, lower, and (ii) lawyers' fees R$ 8.8 million or 49.2% lower.

Provisions for client default

The provision for expected losses due to client default in 4Q23 was R$ 102.3 million, compared to R$ 60.1 million in 4Q22, mainly reflecting: (i) changes in the measurement of these losses put in place in 3Q22 (also with a positive effect in 4Q22), to be more compatible with actual performance of default by the Company's clients in practice.

Impairment

This item in 4Q22 was a negative provision (reversal), of R$ 37.2 million - reversal of an item that had been previously recognized for a client's challenge of an amount payable. The effect of this item was reduced to zero in 4Q23.

Gain on disposal of investments

A gain of R$ 288.3 million on sale of assets was posted in Costs and expenses in 4Q23. Of this total R$ 261.3 million is for the sale of Baguari Energia, and R$ 27.0 million for the sale of Retiro Baixo.

Post-retirement obligations

The impact of the Company's post-retirement obligations on operational profit in 4Q23 was an expense of R$ 161.3 million, compared to an expense of R$ 157.3 million in 4Q22.

Employees' and managers' profit shares

The expense on profit shares for employees and managers was R$ 38.7 million in 4Q23, which compares with a reversal of R$ 15.3 million in 4Q22. The difference is basically due to acceptance by all the unions of the 2023 Collective Work Agreement, and compares with 2022, when some unions did not accept the profit sharing agreement. The result is reflected in the reversal of provision.

People

The expense on personnel in 4Q23 was R$ 348.5 million, 5.3% less than in 4Q22, even after the 6.46% increase in salaries under the Collective Work Agreement of November 2022, and the 4.14% increase of November 2023. The lower figure reflects an expense of R$ 29.1 million on the voluntary severance program of 4Q22, and the average number of employees being 1.2% lower. Excluding the effect of the voluntary severance program the increase would be 2.8%.

CONSOLIDATED EBITDA (IFRS and Adjusted)

·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, nor as a substitute for net profit or operational profit, nor as an indicator of operational performance or cash flow, nor to measure liquidity nor the capacity for payment of debt. The Company adjusts the Ebitda calculated in accordance with CVM Instruction 156/2022, to exclude items which, by their nature, do not contribute to information on the potential for gross cash flow generation, since they are extraordinary items.

§	Cemig has been included in the Dow Jones Sustainability Index for the 24th consecutive year, due to its outstanding social, environmental and economic management practices. It is the only electricity company in the Americas included in the index - with seven others of the sector, all European.

§	in the B3 ISE Corporate Sustainability Index, one of the world's most important ESG indicators, Cemig is included for the 19th consecutive year.

§

Cemig has delivered its 80th new substation in its Mais Energy ('More Energy') Program, in the Zona da Mata region of Minas Gerais, for enhancement of quality of supply to the State's population. A total of R$ 1.7 billion has so far been invested in this structuring program, which is part of the company's largest-ever investment plan. These facilities are fundamental for quality of energy supply, and Cemig's Investments are increasing their number by 50%.

§

Cemig's Energy Efficiency Program has now invested R$ 1 billion in Minas Gerais since its creation in 1998. The program has now reached the entire area of the distribution concession, which includes 774 municipalities in the State of Minas Gerais, benefiting some 900,000 families in the State as a whole.

§

Cemig has joined the 100% Transparency Movement of the UN Global Compact, an initiative that aims to combat corruption and develop responsible and transparent institutions at all levels. Cemig is advancing toward its goals of: 100% transparency of interactions with the Public administration; 100% ethical remuneration of senior management; training in ethics for 100% of the high-risk value chain; 100% transparency in the Compliance and Governance structure; and 100% transparency in relation to the confidential reporting channels.

Environment

§	Cemig has adopted aluminum cable insulated with vegetable-origin material, derived from sugarcane, in its above-ground aerial electricity distribution network. Using sustainably-sourced cable, Cemig contributes to reduction of CO2 emissions in the atmosphere.

§

The possibility of producing food and electricity at the same location will become a reality with Brazil's first agrivoltaic project, a partnership between Cemig, the Minas Gerais Farming Research Company (Epamig), and the Telecommunications Research and Development Center (CPQD). This will be an investment of R$ 10.5 million, with research over 30 months.

Social

§	Cemig runs various programs with the communities living or working around its operations:

§

The Proximidade (Proximity) Program explains the operating and security procedures of its hydroelectric plants to the population, and also provides information on the meteorological and hydrological situation of the related river basins. This quarter, an event was held at the Theodomiro Carneiro Santiago hydroelectric plant, with participation by 29 people from the community, public bodies and civil defense organizations.

§	The Vamos Program aims to raise awareness on safety, and mobilization of the population in the event of emergencies. It holds meetings with civil defense bodies, including simulation training for evacuations of hydroelectric dam areas in the event of significant damage.

§	Training sessions were held in this quarter with the population and civil defense bodies of the ZASs (self-rescue zones) of three hydroelectric plants - Rosal, Queimado and Sá Carvalho - and three Small Hydro Plants: Piau, Coronel Domiciano and Dona Rita - with simulations for evacuation.

§	The Participatory Management Program for the area surrounding the reservoir of the Theodomiro Carneiro Santiago hydroelectric plant held three meetings of its Management Committee Working Group.

§	The Participatory Management Program for the area surrounding the Salto Grande hydroelectric plant held a meeting with communities within that area (Braúnas, Dores de Guanhães, Ferros and Joanésia).

§	The Participatory Management Program for the area surrounding the reservoir of the Irapé hydroelectric plant held a meeting with the local community.

§	The Environmental Education Program of the Theodomiro Carneiro Santiago hydroelectric plant held two environmental education events at schools in the municipalities of the area surrounding the reservoir (Grupiara and Catalão).

§	The Environmental Education Program of the Rosal hydroelectric plant held two environmental education events at schools in municipalities in the area around the reservoir (Bom Jesus do Itabapoana and Guaçuí).

COMPANHIA ENERGÉTICA DE MINAS GERAIS - CEMIG ("CEMIG" or "Company"), a publicly-held company with shares traded on the stock exchanges of São Paulo, New York, and Madrid, hereby informs, under CVM Resolution 44/2021, of August 23, 2021, the Brazilian Securities and Exchange Commission (CVM), B3 S.A. - Brasil, Bolsa, Balcão ("B3"), and the market in general that, on this date, CEMIG GERAÇÃO E TRANSMISSÃO S.A. ("CEMIG GT"), a wholly-owned subsidiary of Cemig, approved and executed a contract for the disposal of its direct equity interest of 45% in the share capital of Aliança Energia S.A. ("Aliança") to Vale S.A. ("Vale"). Aliança is made up of seven hydroelectric power plants located in the state of Minas Gerais, two operational wind power plants in the state of Rio Grande do Norte and one wind complex in the final phase of implementation in the state of Ceará. Together, these assets have an installed capacity of 1,438 MW and an average physical guarantee of 755 MW.

The effectiveness of the contract is subject to the approval of the transaction by the Company's Extraordinary Shareholders Meeting and compliance with conditions precedent ("CP") that are common for this type of transaction, among which approval from the Brazilian Antitrust Authority ("CADE") and the Brazilian Electricity Regulatory Agency ("ANEEL").

The cost of the transaction is R$2.7 billion, with a base date of June 30, 2023, restated by the CDI rate from that date up to the date prior to the actual closing of the transaction. Dividends and Interest on Equity distributed or approved up to the closing of the transaction will be discounted from said amount. Furthermore, CEMIG GT will be entitled to an additional amount equivalent to 45% of the future indemnification that might be received by Aliança, referring to the losses arising from the Fundão tailings dam disaster (Mariana dam disaster), involving the Risoleta Neves (Candonga) Hydroelectric Power Plant, with a reference amount of R$223 million for contractual purposes - also restated by the CDI rate from the base date.

This disposal was negotiated under the "lump-sum purchase" category, exempting Cemig GT from any indemnification related to Aliança, its assets, and liabilities.

This disposal is also in line with the Company's Strategic Planning, which provides for the divestment of Grupo Cemig's minority interests.

CEMIG and CEMIG GT reaffirm their commitment to keeping shareholders, the market in general, and other stakeholders duly and timely informed about this matter, under the rules issued by the CVM and legislation in force.
