1Q19 RESULTS

Cemig reports net profit of R$ 797,239 in 1Q19, compared to R$ 464,595 in 4Q18.

This higher figure was due to:

| ◾ | sales of power to final consumers of Cemig GT 5.1% higher year-on-year;

| ◾ | Cemig GT’s revenue from transactions on the Wholesale Power Exchange (CCEE) 112.94% higher, due to a greater seasonal effect in 1Q19, associated with higher Generation Scaling Factors (GSF), with a higher volume of sales in the secondary market;

| ◾ | Net financial revenue of R$ 152,311, reflecting the effects of the gain in value of the hedge for the Eurobond issue

Cemig’s consolidated electricity market

The Cemig Group sells electricity through its distribution company, Cemig Distribuição (‘Cemig D’), its generation and transmission company, Cemig Geração e Transmissão (‘Cemig GT’), and other wholly-owned subsidiaries: Horizontes Energia, Sá Carvalho, Cemig PCH, Rosal Energia, CE Praias de Parajuru, CE Volta do Rio, Cemig Geração Camargos, Cemig Geração Itutinga, Cemig Geração Salto Grande, Cemig Geração Três Marias, Cemig Geração Leste, Cemig Geração Oeste, and Cemig Geração Sul.

These companies sell electricity to:

(I) | Captive consumers in Cemig’s concession area in the State of Minas Gerais;

(II) | Free Consumers in both the State of Minas Gerais and other States of Brazil, in the Free Market (Ambiente de Contratação Livre, or ACL);

(III) | other agents of the electricity sector – traders, generators and independent power producers, also in the ACL; and

(IV) | Distributors, in the Regulated Market (Ambiente de Contratação Regulada, or ACR).

In 1Q19 the Cemig group sold a total volume of 13,758,035 MWh, which was 6.2% more than in 1Q18.

Sales of electricity to final consumers, plus Cemig’s own consumption, totaled 10,680,542 MWh, or 3.5% plus than in 1Q16.

Residential

Residential volume was 5.81% higher in 1Q19 than 1Q18, reflecting three factors:

| ◾ | high temperatures in the period;

| ◾ | addition of 60,771 new consumer units;

| ◾ | more calendar days in 1Q19 (92.5 days) that in 1Q18 (89.8 days).

Industrial

Industrial volume was 2.24% higher in 1Q19 than 1Q18, reflecting two factors:

| ◾ | in gthe captive market, one major new high voltage client (A2) was added later in 2018, not included in the comparison base in the first quarter of 2018; and

| ◾ | the volume of power transported was higher, mainly due to increases in (i) ferro alloys (4.00%)and (ii) extractive industries (9.50%).

Commercial and Services

Volume sold to this user category was 2.70% higher year-on-year, mainly reflecting higher temperatures in the period. It also reflects a reduction of 0.65% in the volume of energy billed to captive consumers; and volume of energy transported for free clients 33.16% higher year-on-year. The significant growth in total consumption by Free Market customers mainly reflects an increase in their number – there were 17.5% more Free Consumers in 1Q19 than 1Q18.

Rural

Consumption by rural consumers 12.32% higher year-on-year in 2019 mainly reflects lower rainfall in the period. Consumption by irrigation users was 31.8% higher, while the increase for all other conventional farming was 6.0%.

The electricity market of Cemig GT

Cemig GT billed a total of 6,994,836 MWh in 1Q19, 6.49% more than in 1Q18.

The number of clients billed by Cemig GT was 5.14% higher than at the end of March 2018, totaling 1,678. Of these: 1,313 were industrial, commercial and rural clients, 28 were distribution companies, and 29 were companies in the category of traders, generators and independent power producers.

Consumption by industrial clients was 5.73% lower year-on-year, due to a higher seasonal effect at the beginning of 2019, in which less power was allocated in the first half and more in the second half of the year. Meanwhile, consumption in the commercial market segment was 33.16% higher year-on-year, due to an increasing number of clients migrating from the captive market to the free market. Cemig GT added 94 commercial clients from March 2018 to March 2019.

In 1Q19 total sales to traders were 2,407,704 MWh, or 21.02% more than in 1Q18. In February 2019, Cemig had a high volume of excess supply, which was partially sold to traders.

Sales in the Regulated Market in 1Q19, including sales to Cemig D, totaled 599,280 MWh, or 5.08% less than in 1Q18, due to a difference in seasonal variations of the distributors, and contractual adjustments.

Revenue from Use of Distribution Systems (the TUSD charge)

This is revenue from charging Free Consumers the Tariff for Use of the Distribution System (TUSD), on the volume of energy distributed. In 1Q19 this revenue was R$ 630,044, or 68.58% more than in 1Q18 (R$ 373,741) – the higher figure reflected the increase of 65.60% granted for the TUSD in the Annual Tariff Adjustment (covering both power transport volume, and demand levels) in effect from May 2018 (full effect in 2019).

CVA and Other financial components in tariff adjustments

In its interim accounting information Cemig recognizes the difference between actual non-controllable costs (in which the contribution to the CDE – the Energy Development Account – and electricity bought for resale, are significant components) and the costs that were used in calculating rates charged to consumers. In 1Q19 the amount for reimbursement in the subsequent tariff was R$ 120,350 – this is 72.72% below the amount subject to reimbursement in 1Q18, of R$ 441,156. The difference mainly reflects higher costs of power supply in 2018, in relation to the coverage by the tariff (this difference generates a higher financial asset to be reimbursed to the Company through the next tariff adjustment).

Updating – Selic rate |  |  | 20,906 |
Balance at Mar. 31, 2019 |  |  | 1,147,415 |

The increase in the balance of CVA receivable was mainly the result of increased costs of electricity in 2018 – resulting in a higher difference between the actual expense and the amount allocated for this in the tariff calculation. This difference generates a financial asset to be reimbursed to the Company in the next tariff adjustment.

Payments from the Flag Tariff Centralizing Account

The ‘Flag Account’ (Conta Centralizadora de Recursos de Bandeiras Tarifárias – CCRBT or ‘Conta Bandeira’) manages the funds that are collected from captive customers of distribution concessions and permission holders operating in the national grid, and are paid, on behalf of the CDE, directly to the Flag Account. The resulting funds are passed through by the Wholesale Trading Chamber (CCEE) to distribution agents, based on the differences between (a) realized costs of thermal generation and exposure to short-term market prices and (b) the amounts covered by the tariff.

Revenue from transactions on the Wholesale Trading Exchange (CCEE)

Revenue from transactions in energy on the CCEE in 1Q19 was R$ 252,616, or 88.06% higher than in 1Q18 (R$ 134,327). The higher figure mainly reflects higher physical guarantee allocations, and higher Generation Scaling Factors (GSFs) in 1Q19 than in 1Q18, increasing the available excess supply – and this excess supply was valued at a higher Spot Price (PLD) than in 1Q18, contributing to the higher figure for revenue from transactions on the CCE.

Revenue from supply of gas

Cemig reports revenue from supply of gas totaling R$ 596,278 in 1Q19, compared to R$ 428,071 in 1Q18 – 39.29% higher YoY. This is basically due to the higher volume of gas sold to the market of thermoelectric generating plants in 1Q19 than in 1Q18.

Taxes and charges on Revenue

The total of these taxes and charges, reported as deductions from revenue, was R$ 3,141,524 in 1Q19 – or 15.75% more than in 1Q18 (R$ 2,713,992).

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 scarcity is more intense. Activation of the flag tariffs generates an impact on billing in the subsequent month.

Consumer charges resulting from the ‘Flag’ tariff system were higher in 1Q19, at R$ 111,156, than in 1Q18 (R$ 116,771) – or 90.45% lower year-on-year.

The lower figure is because no ‘red’ or ‘yellow’ flag tariffs were activated in first quarter 2019 – the entire quarter took place under the ‘green’ flag. By contrast, in December 2017, the ‘red’ tariff band was in force, at Level I, with effects on the amount billed in January 2018.

Operational costs and expenses

Operational costs and expenses totaled R$ 4,750,116 in 1Q19, or 13.14% more than in 1Q18 (R$ 4,198,293). The following paragraphs comment on the main variations:

Personnel

The expense on personnel in 1Q19 was R$ 365,041, or 10.06% more than in 1Q18 (R$ 331,664).

The increase arises from: accounting of an expense of R$ 21,491 on the 2019 Programmed Voluntary Retirement Plan – corresponding to 155 employees joining the plan; from the 4.00% salary increase in effect from November 2018; and from the increase in the number of employees arising from the result of the latest public competition.

2019 Programmed Voluntary Retirement Plan

In March 2019, the Company approved reopening of the voluntary retirement plan (as the ‘2019 PDVP’), for applications made over the period April 1–10, 2019; and also changes to the requirements for qualification, but with the same financial advantages, which include: the payments specified by law for non-voluntary severance, including payment for the period of prior notice; and deposit of the 40% ‘penalty payment’ of the amount in the employee’s FGTS account, which is formally applicable by law only to non-justified dismissals; and the other payment, specified in the legislation.

Electricity purchased for resale

This expense in 1Q19 was 14.60% higher YoY, at R$ 2,594,181, which compares with R$ 2,263,693 in 1Q18. This arises mainly from the following items:

| ◾ |  | (i) Higher expenses on purchase of supply in the spot market: R$ 513,977 in 1Q19, compared to R$ 219,111 in 1Q18. This variation arises mainly from transactions in supply on the CCEE (Wholesale Training Exchange). The power supply deficit in January and February 2019, with total volume of 50,228 MWh – which made it necessary to buy supply on the spot market. In 1Q18, there was an excess of supply, of 223,166 MWh, resulting in sales on the CCEE, consequently reducing the net expense in that period.

| ◾ |  | (ii) Expenses on supply from Itaipu 15.58% higher, at R$ 333,156 in 1Q19, compared to R$ 288,243 in 1Q18. This is mainly due to the higher exchange rate for the dollar in 1Q19 than 1Q18.

This 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 subsequent tariff adjustment.

Default

In 2019 the economy was marked by two main features: instability in the financial market, and continuation of the slow process of recovery in economic activity.

In spite of the GDP growth reported for 2018, we note that certain indices at the start of 2019 call for caution – such as increasing levels of unemployment, and reduction in levels of business confidence.

To be sure of overcoming the effects of an economic scenario that still appears to be unfavorable, and to combat the historic level of default, in 2019 Cemig is maintaining its high levels of efforts for collection from consumers that are in default. Some results have already been achieved. The level in 1Q19 was the same as in 2018. Since December 2016 there has been no significant increase in Cemig’s default percentages, showing that this situation is being held under control. In the residential consumer category – the largest proportion of the captive market, results in 2019 are showing a more optimistic outlook – with default 12% lower than in 1Q18. In view of this, we expect to see a fall in the total financial volume of default from now on.

Cemig uses various tools of communication and collection to prevent increase in default. These include contact by telephone and email, collection requests by text and by letter, negative posting on credit registers, collection through the courts and, principally, disconnection of supply. Aneel Resolution 414 allows supply to be cut off after 15 days from receipt of a notice by a defaulting consumer.

The company is continuing with a robust plan for consumer disconnections in 2019, under which it expects to carry out more than 1 million consumer disconnections – over the aggregate of all the types of consumer – in a year, for the second year running.

With more intense application of the tools for collection, and actual disconnection of past due consumers, the Company is even more confident that default indices will be reduced in the coming periods.

Gas bought for resale

In 1Q19 the Company recorded an expense of R$ 394,982 on acquisition of gas, 50.05% more than its comparable expense of R$ 263,233 in 1Q18. This is basically the result of the volume of gas sold being 19% higher (at 315,240 m³ in 1 Q19, compared to 264,115 m³ in 1Q18), and an increase of 37% in the cost of gas bought from Petrobras.

Post-retirement obligations

The impact of the Company’s post-retirement obligation on operating profit was an expense of R$ 100,909 in 1Q19 – which compares with an expense of R$ 83,271 in 1Q18. This is mainly the result of reduction in the discount rate used in the actuarial calculation – which increased the amount of the actuarial liabilities, and consequently the scale of the expense reported.

Share of profit (loss), net, of associates and joint ventures

The net loss from equity method calculation of gains in non-consolidated investees in 1Q19 was a gain of R$ 67,226, compared to a gain of R$ 56,874 in 2018. The losses recognized in 1Q18 were basically related to the investments in: (a) Renova, and (b) Santo Antônio Energia. No loss on the investment in Renova was recognized in 1Q19, since this had been written off in December 2018, due to that investees uncovered liabilities. Also, the negative equity method result from the investment in Santo Antônio Energia was 74.28% lower in 1Q19 than in 1Q18.

Financial revenue and expenses

Cemig reported net financial expenses in 1Q19 of R$ 101,560, which compares with net financial expenses of R$ 157,800 in 1Q18. The main factors are:

| ◾ |  | Higher gain on the hedge transactions contracted to protect the Eurobond issue: the gain in 1Q19 was R$ 152,311, compared to a gain of R$ 97,517 in 1Q18. The higher figure was the result of the dollar future curve moving upward, resulting in both the call spread and the asset becoming more valuable; and also due to the curve for the future DI interest rate (the liability side of the transaction) moving downward, contributing to an increase in fair value.

| ◾ |  | Higher net result of monetary updating on the balances of CVA and Other financial components in tariff adjustments: net gain of R$ 20,906 in 1Q19, compared to net gain of R$ 447 in 1Q18, basically reflecting the higher balance of net assets in 1Q19 than in 1Q18.

Ebitda

Cemig’s consolidated Ebitda in 1Q19 was 45.10% higher than in 1Q18. The higher figure basically portrays sales of power supply to final consumers 3.51% higher year-on-year, and sales of power supply on the CCEE (Wholesale Trading Exchange) 88.06% higher year-on-year. Ebitda margin in 1Q19 was 24.71%, compared to 20.41% in 1Q18.
