PROPOSAL

BY THE

BOARD OF DIRECTORS

TO THE

ORDINARY AND EXTRAORDINARY

GENERAL MEETING OF STOCKHOLDERS

TO BE HELD CONCURRENTLY, EXCLUSIVELY ONLINE, ON

APRIL 30, 2021, AT 11 A.M.

Dear Stockholders:

The Board of Directors of Companhia Energética de Minas Gerais (Cemig) –

Whereas –

“The total of profit reserves, excluding reserves for contingencies, the Tax incentive reserve, and the Future earnings reserve, may not exceed the share capital. When this limit is reached, the general meeting must decide on application of the excess in paying-up or increasing the share capital, or distribution of dividends”.

On December 31, 2020, the Company’s share capital was R$ 7,593,763,000; and the Profit reserves, excluding the Tax incentive reserve and the Future earnings reserve, totaled R$ 9,123,134,000, exceeding the share capital by R$ 1,529,371,000.

Thus to comply with the legislation, the Company may now increase its share capital, by issuance of a bonus in shares (a stock bonus), using the balance in the Retained Earnings Reserve.

An increase in the share capital of 10.07%, or R$ 764,686,000 is sufficient to meet the requirement of the Brazilian legislation.

The limit available on the SEC for issuance of new ADRS is R$ 26,174,000.

The Company’s current total of ADRS is 227,670,000, so it is possible to increase the quantity of ADRS by 11.50%.

Increasing the share capital from R$ 7,593,763,000 to R$ 8,466,810,000 represents an increase of 11.496899948%, with issuance of 174,609,467 new shares, with par value, in accordance with the by-laws, of R$ 5.00 (five Reais) of which the common shares total 58,366,345 and the preferred shares total 116,243,122.

The new share capital, of R$ 834,603,000, will comprise 566,036,634 common shares, and 1,127,325,434 preferred shares, making a total of 1,693,362,068 shares.

The legislation requires the fractions of shares resulting from the capital increase to be sold on an exchange and the proceeds distributed proportionally to the Company’s stockholders.

To simplify the distribution of the proceeds of the sale of fractions of shares, the payment may be made on the same date as payment of the mandatory dividends.

– now proposes to the Ordinary and Extraordinary General Meetings as follows:

1.   Approval of the Report of Management and the Financial Statements for the year ended December 31, 2020, and the related complementary documents:

2.   Approval of the allocation of: the Net profit for the business year 2020: R$ 2,864,110,000, realization of the deemed cost of fixed assets: R$ 16,950,000, adjustments to prior years, of : R$ 211,640,000, and realization of the Retained earnings reserve constituted in 2019, in the amount of R$ 834,603,000, as follows:

3.   Election of members of the Board of Directors, due to vacancy.

4.   Election of one alternate member to the Company’s Audit Board, in substitution.

5.   Approval of setting of the total remuneration of the Managers, members of the Audit Board, and members of the Audit Committee, in the amount of R$ 23,259,187.88.

6. (i) Authorization of increase in the share capital from R$ 7,593,763,000, to: R$ 8,466,810,000 by an issue of 174,609,467 one hundred seventy four million, six hundred nine thousand four hundred sixty seven) new shares, comprising 58,366,345 (fifty eight million three hundred sixty six thousand three hundred forty five) nominal common shares with par value of R$ 5.00 (five Reais) and 116,243,122 (one hundred sixteen million two hundred forty three thousand one hundred twenty two) nominal preferred shares with par value of R$ 5.00 (five Reais), through capitalization of R$ 873,047,335 from the Retained earnings reserve, with distribution to stockholders, as a result, of a stock bonus of 11,496899948% in new shares of the same type as those held and with par value of R$ 5.00 (five Reais);

(ii)  If item (i) above is approved, authorization of change to the head paragraph of Article 4 of the by-laws, now to read as follows:

“ Clause 1 – The share capital of the Company is R$ 8,466,810,340.00, (eight billion four hundred sixty six million eight hundred ten thousand three hundred forty Reais), represented by:

(iii)        Authorization of the following measures to be taken by the Executive Board in relation to the stock bonus:

As can be seen, the objective of this proposal is to meet the legitimate interests of the stockholders and of the Company, and for this reason it is the hope of the Board of Directors that it will be approved.

MATERIAL ANNOUNCEMENT

Renova: Ratification of capital increase

CEMIG (Companhia Energética de Minas Gerais, listed in São Paulo, New York and Madrid), in compliance with CVM Instruction 358 of January 3, 2002 as amended, hereby reports to the Brazilian Securities Commission (CVM), the São Paulo Stock Exchange (B3) and the market as follows:

Cemig’s affiliated company Renova Energia S.A. (‘Renova’) today issued the following Material Announcement:

The capital increase was ratified in the amount of R$ 334,396,776.50, represented by 58,422,742 nominal preferred shares without par value, comprising 19,502,468 common shares and 38,920,274 preferred shares.

The credits of all creditors requesting capitalization during the ‘First Conversion Request Window’ were capitalized, resulting in the total of the eligible debt in the Judicial Recovery proceedings being reduced by 12.6%.

As a result the share capital of Renova is increased to R$ 3,295,172,753.48, comprising 100,142,466 nominal shares without par value, of which 50,854,986 are common shares and 49,287,480 are preferred shares. ”

As stated in the Material Announcement of March 1, 2021, Cemig GT, a stockholder of Renova, is not part of the group of creditors that applied for conversion of their credits into shares, and thus did not take part in the said capital increase.

The interest of Cemig GT in the equity of Renova has thus been reduced as follows:

Holding in the voting stock: reduced from 48.21% to 29.72%; interest in the total capital: reduced from 36.23% to 15.09%.

Cemig confirms that this conversion has no effect on Cemig GT’s rights in the controlling stockholding block of Renova.

Adoption of IFRS

The results presented below are prepared in accordance with Brazilian accounting rules, which now embody harmonization to IFRS (International Financial Reporting Standards). Figures are in thousands of Reais (R$ ’000) unless otherwise stated.

INCOME STATEMENT

(In thousands of Reais)

Results separated by business segment

Consolidated results for 1Q21

In thousands of Reais (R$ ’000), unless otherwise stated.

For the first quarter of 2021 (1Q21) Cemig reports net profit of R$ 422,351, which compares to a net loss of R$ 68,133 in the (re-presented) result for 1Q20.

Leading factors in the first quarter 2021 result were:

Consolidated operational revenue

Revenue from supply of electricity:

Total revenue from supply of electricity was R$ 6,951,837 in 1Q21, compared to R$ 6,767,438 in 1Q20, a year-on-year increase of 2.7%.

Final consumers

Revenue from energy sold to final consumers in 1Q21 was R$ 6,275,015. This is 7.2% higher than in 1Q20 (R$ 5,855,898), and reflects volume of energy sold to final consumers 2.7% higher, especially to industrial clients (13.7% higher), rural consumers (9.0% higher), and residential consumers (3.2% higher), partly offset by commercial consumption 13.8% lower.

Revenue from Use of Distribution Systems (the TUSD charge)

This is 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 1Q21 this revenue was R$ 836,735, 15.5% more than in 1Q20 (R$ 724,371). This is mainly due to revenue from transport of energy 9.7% higher YoY in 1Q21, and also to the Company’s Annual Tariff Adjustment, which represented an increase of 10.16% for Free Consumers, as from June 30, 2020. After recalculation of the Tariff Adjustment, on August 19, 2020, the effect on Free Consumers changed to 5.74%.

CVA and Other financial components in tariff adjustments

The Company recognizes the difference between actual non-controllable costs (in which the CDE, and electricity bought for resale, are significant components) and the costs that were used as the basis for decision on the rates charged to consumers. A revenue of R$ 338,907 was posted in 1Q21, compared to a negative amount of R$ 54,602 in 1Q20. The main factors are higher cost of energy from Itaipu, due to the increase in the US dollar exchange rate, and higher transmission costs than the amounts recognized in the tariff. The balance of the CVA at the end of 1Q21 was R$ 98,641 negative.

Changes in balances of financial assets and liabilities:

Transmission revenue

The transmission revenue of Cemig GT and Centroeste comprises the sum of revenues recorded for construction, enhancement, operation and maintenance, as specified in the transmission contracts. The concession contracts establish the Permitted Annual Revenue (Receita Anual Permitida – RAP) for the assets of the existing system and those won in competitive tenders, updated annually, based mainly on the IPCA inflation index (the IPCA index is applied to the contracts of Cemig GT, and the

IGP–M index is applied to the contract of Cemig Itajubá). From then on, whenever there is a strengthening or enhancement of an existing asset made under a specific authorization from Aneel, an addition is made to the RAP.

Revenue from operation and maintenance was R$ 89,162 in 1Q21, and R$ 76,597 in the 1Q20 result (re-presented) – an increase of 16.4%. Revenues from construction, strengthening and enhancements of infrastructure in 1Q21 were R$ 22,451, compared to R$ 61,241 in the 1Q20 results (re-presented) – a reduction of 63.3%, mainly reflecting lower investments in transmission in 2021, following decisions to review investments on small-scale enhancements, due to alterations in regulations, and suspension of contracts with suppliers for enhancement works. At the same time, revenues from financial remuneration of transmission contractual assets were 119.7% higher, at R$ 157,255 in 1Q21, compared to R$ 71,580 in the (re-presented) results for 1Q20 – mainly reflecting the increase in the remuneration base of assets linked to concession contracts, as from the Periodic Tariff Review (RTP) ratified by Aneel on June 30 and December 30, 2020.

Revenue from transactions on the Power Trading Exchange (CCEE)

Revenue from transactions in electricity on the CCEE in 1Q21 was R$ 107,045, compared to R$ 87,824 in 1Q20 – an increase of 21.9% year-on-year. This revenue was affected in 1Q20 by the lower excess supply of Cemig GT traded and settled on the CCEE, reflecting the strategy of directing more supply for sale to traders for the period.

Revenue from supply of gas

The Company reports revenue from supply of gas 26.0% higher YoY in 1Q21, at R$ 705,185, compared to R$ 559,660 in 1Q20. This difference basically reflects volume of gas sold 35.0% higher, at 337,576m³ in 1Q21, compared to 250,136m³ in 1Q20, mainly reflecting much higher consumption by the thermoelectric electricity generation sector – 189.0% higher YoY – and the industrial consumer category, which consumed 11.0% more volume YoY.

The total number of Gasmig’s clients increased by 2,203 in 1Q21. Supply to the residential market began in 2013, and at the end of March 2021 Gasmig was serving 62,128 households – 3.3% more than at the end of December 2020.

Taxes and charges on revenue

The total of the taxes and charges reported as deductions from revenue in 1Q21 was R$ 3,123,277, or 3.7% higher than in 1Q20 (R$ 3,012,084).

The Energy Development Account – CDE

The amounts of payments to the Energy Development Account (CDE) are decided by an Aneel Resolution. The purpose of the CDE is to cover costs of concession indemnities (reimbursements of costs of assets), tariff subsidies, the subsidy for balanced tariff reduction, the low-income-consumer subsidy, the coal consumption subsidy, and the Fuels Consumption Account (CCC). The CDE charges in 1Q21 were R$ 674,869, 10.7% more than in 1Q20 (R$ 609,710). 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.

Consumer charges – the ‘Flag’ Tariff system

The ‘Flag’ Tariff bands are activated as a result of low levels of water in the system’s reservoirs – tariffs are temporarily increased due to scarcity of rain. The ‘Red’ band has two levels – Level 1 and Level 2. Level 2 comes into effect when the levels of reservoirs are more critical. Activation of the flag tariffs generates an impact on billing in the subsequent month.

The additional charges represented a credit of R$ 48,020 in 1Q21, compared to an expense of R$ 59,583 in 1Q20. The positive amount in 1Q21 is due to reversal of the provision for the charge in December 2020, which was higher than the calculation of the actual charges for 1Q21. Since the Company’s position with the Flag Account is in credit, these amounts were reversed in their entirety, and the effect of the amounts invoiced to the consumer under the Flag system is reflected as an advance of sector financial assets.

This higher figure reflects application of the ‘red 2’ tariff flag in December 2020 (affecting billing of January 2021), and ‘yellow” in January and February 2021.

Operational costs and expenses

Operational costs and expenses in 1Q21 totaled R$ 5,736,896, or 14.3% higher than in 1Q20 (R$ 5,018,133).

The following paragraphs comment on the main variations in expenses:

Personnel

The expense on personnel in 1Q21 was R$ 307,454, or 1.3% less than in 1Q20 (R$ 311,606). The lower figure reflects the number of employees being 4.97% lower, at 5,334 in 1Q21, compared to 5,334 in 1Q20, partially offset by the salary increase of 4.77% from November 2020, under the Collective Work Agreement.

Number of employees – by company

Employees’ and managers’ profit shares

This expense in 1Q21 was R$ 29,514, compared to R$ 25,840 in 1Q20. The calculation of this expense is based on adjusted profit and not on IFRS profit, and also taking into account the established goals.

Electricity purchased for resale

The expense on electricity bought for resale in 1Q21 was R$ 3,108,114, 10.4% higher than in 1Q20 (R$ 2,814,495). This arises mainly from the following factors:

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.

Gas purchased for resale

In 1Q21 the Company’s expense on acquisition of gas was R$ 387,525, 24.2% higher than its comparable expense of R$ 311,925 in 1Q20. This difference basically reflects volume of gas sold 35.0% higher, at 337,576m³ in 1Q21, compared to 250,136m³, mainly due to consumption by the thermoelectric power generation sector 189.0% higher than in 1Q20.

Charges for use of the transmission network

Charges for use of the national grid in 1Q21 were R$ 746,312, or 104.5% more than in 1Q20 (R$ 365,012). This expense is payable by electricity distribution and generation agents for use of the facilities that are components of the national grid. The amounts to be paid are set by an Aneel Resolution. The higher figure is mainly due to the annual adjustment in charges for use of the National Grid, which usually takes place in July, and which had an effect of approximately 27.4% in 2020, compared to 2019. Also, there was higher dispatching of thermal plants outside the ‘merit order’, for energy security, in 1Q21, and consequently their high cost increased the System Service Charges (CCEE-ESS), which are also part of this account line, from R$ 48,418 in 1Q20 to R$ 253,198 in 1Q21.

Operational provisions

Operational provisions made in 1Q21 constituted an expense of R$ 24,204. This compares to R$ 159,116 in 1Q20. This arises mainly from the following factors:

Default – Cemig D

The Covid-19 pandemic was especially challenging for the Company due to the unprecedented nature of the effects on its mechanisms of collection of amounts payable by clients. The tightest moment was in the second quarter of 2020, under the effects of rules restricting mobility, limiting our employment of tools for collection, especially including disconnection, and the strong retraction in the economy. Indices began to improve only slowly, as from May and June, stabilizing in the fourth quarter, to higher than 97% of collectible revenue, as a result of the plan for mitigating default. The plan was based on daily monitoring of the indicators of revenue collection and default, with intensification and improvement of collection tools, widening of channels of communication, and flexible extension of the rules for payment by installments, applying sensitivity to the income situation of families during the pandemic. To try to mitigate the impacts of the pandemic and help sustain its clients’ payment capacity, Cemig launched its special payment conditions to help, principally, low-income clients, hospitals and micro-companies. New channels of payment, such as debit and credit cards, PicPay and accreditation of online banks were also put in place, to expand consumers’ payment options.

Disconnection of defaulting clients was also an important measure in the combat of default. Approximately 330,000 customer disconnections were made in 1Q21, 60% more than in 1Q20, including the start of the massive “Remote Disconnection” operation by the company.

In 1Q21, the collection rate remained at a higher level than in previous periods, despite the continuation of the effects of the pandemic.

Receivables Collection Index: (Collection/Billing), % – 12-month moving average

Equity in earnings of non-consolidated investees

The Company posted equity method gains of R$ 118,687 in 1Q21, 44.8% more than in 1Q20 (R$ 81,492). This improvement mainly reflects an increased equity method gain in the investee Taesa, which was R$ 122,328 in 1Q21, compared to R$ 77,152 in 1Q20. It also reflects a positive equity method gain in the investee Guanhães, of R$ 40,254, which compares to an equity method loss of R$ 358 in 1Q20. Within the same total, there was also an equity method loss of R$ 52,627 for the interest in Santo Antônio.

Consolidated Ebitda

Cemig’s consolidated Ebitda in 1Q21 was 133.3 higher than in 1Q20; adjusted Ebitda was 22.9% higher. Ebitda margin was 23.3% in 1Q21, compared to 22.3% in 1Q20.

(1) Ebitda is a non-accounting measure prepared by the Company, reconciled with the consolidated Interim accounting information in accordance with CVM Circular SNC/SEP 1/2007 and CVM Instruction 527 of October 4, 2012. It comprises Net profit adjusted by the effects of net Financial revenue (expenses), Depreciation and amortization, and Income tax and 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 variables 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 substitution 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.

(2) The Company adjusts Ebitda, as calculated in accordance with CVM Instruction 527/2012, 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.

Ebitda of Cemig GT
