From the CEO and CFO

Cemig’s CEO, Mr. Djalma Bastos de Morais, comments:

“Cemig’s 3Q12 results are in line with the guidelines laid down in our Long-term Strategic Plan. Maintaining its growth strategy, Cemig ensures its leadership position in consolidation of the Brazilian electricity sector.  As part of this context, the company’s recent decisions aim to ensure funding for continuity of the Company’s policy of investments, including those associated with opportunities for new projects and acquisitions — contributing to the development of Brazil’s electricity sector and the provision of service to our consumers with quality and efficiency.”

Cemig’s CFO, Mr. Luiz Fernando Rolla, says:

“In third quarter 2012 Cemig earned Ebitda of R$ 1.8 billion, showing its strong capacity to generate operational cash flow through its diversified portfolio of businesses and its high levels of operational efficiency.  Our resulting net profit in the period is R$ 937 million, 43% more than in the same period of 2011. Our solid balance sheet, also reflected by our cash position of R$ 4.7 billion, supports continuity of the company’s projects, with an investment program always focused on profitability and addition of value for our stockholders in the long term, and for the community that we serve. Below — in this release — we present our highlights for 3Q12. “

Cemig, 3Q12: Key numbers

·                   Cash flow, measured as Ebitda, of R$ 1.8 billion in 3Q12, 18% more than in 3Q11.

·                   Net income up 43.0% from 3Q11, at R$ 937 million.

·                   Non-recurring gain of R$ 259mn in 3Q12, arising from dilutions of a stockholding interest in jointly-controlled subsidiaries*

*(This is described in more detail in Note 12 to the Quarterly Information (ITR) published by the Cemig Holding Company).

·                   Net revenue of more than R$ 4.8 billion in 3Q12 — robust growth of 19.0%, from 3Q11.

The economic context

Weak global economic activity continues to be the focus of uncertainty in 2012. The highlight is the threat to the Eurozone posed by the continuing fiscal tension in many of its countries — while in the US, slow below-potential growth, a historic unemployment level, and lack of a specific forward outlook on the “Fiscal Cliff”, are tending to hold back any significant progress on recovery.

In China, too, there is a moment of uncertainty, due to both the political transition and also the effects of the relative cooling of its economic growth in the context of the recent slowdown in growth rates worldwide. However, based on the improvement in certain economic activity indicators, and the short-term effects of monetary and fiscal easing policies, China’s economy is still expected to expand by more than 7.5% in 2012.

Brazil’s economic scenario continues to stand out from this overall perturbed international picture.  Its debt/GDP ratio continues to fall, and inflation is showing signs that it will be within the target range by the end of the year. The country’s robust international reserves of US$400 billion; its advanced and solid financial system; and the fiscal responsibility regime governing the states and municipalities all help to expand investors’ confidence in the country.

As a result Brazil still stands out as one of the world’s principal destinations for investors, as shown by foreign direct investment (FDI) equal to nearly 2.5% of GDP.  We expect the fiscal and monetary stimulus measures now in place — mainly affecting industry — to result in a resurgence in Brazilian economic activity as 2012 comes to a close.

Market forecasts are now indicating annualized Brazilian GDP growth of 4% in the fourth quarter of this year, likely maintained until the end of 2003.

Renewal of concessions — Provisional Measure 579 of September 11, 2012

On September 11, 2012, Brazil’s federal government issued Provisional Measure 579 (“PM 579”), governing renewals for 30 years of electricity distribution, transmission and generation concessions that meet the renewal criteria in Law 9074/1995, made provisions for bringing forward the date of expiry of present concessions, requiring concession holders to sign an extension contract with the concession granting power (the federal government).

PM 579 makes extension of a concession conditional on express acceptance of criteria for remuneration, allocation of supply, and quality standards specified in it. It also specifies that indemnity of assets that have not yet been amortized or depreciated should be on the basis of replacement value — with the exception of transmission assets that existed on May 31, 2000, which are considered to be 100% amortized.

Finally, concessions that are not extended on the basis laid down in the Measure are to be offered by tender — by auction or by competing bids — for up to 30 years.

Cemig, through its subsidiaries and affiliated companies, has approximately 7 GW of installed generation capacity, and 5,000 kilometers of transmission lines, which will be affected to a greater or lesser degree by the measures announced.

In compliance with the procedure laid down in the Provisional Measure, on October 15, 2012 Cemig submitted to the Brazilian electricity regulator, Aneel, its statement of interest in extending those of its electricity transmission

15

Table of Contents

and generation Concession Contracts which, in Cemig’s understanding, were within the criteria specified in the Measure, without prejudice to any possible rights specified in the conversion law.

In accordance with the provisions and timing in PM 579, Ministerial Orders 578 and 579 of October 31, 2012, issued by the Mining and Energy Ministry (MME), laid down initial tariffs for the hydroelectric plants that come within the definition in Clause 6 of PM 579, applying to concession renewals brought forward under it.

On November 1, 2012, Interministerial Order 580, issued by the Mining and Energy Ministry and the Finance Ministry, set out the amounts of indemnity to be paid to holders of generation and transmission concessions that opt to bring forward renewals of concessions.

As mentioned above, renewals of the following concession contracts were required:

1. Concessions for electricity generation service, for the generating plants listed below, contained in Concession Contract 007/97 (Cemig — Generation), with provisos relating to the price of electricity, residual value of assets and operational conditions. For these concessions, Interministerial Order 580 of the Mining and Finance Ministries specifies that there will be no indemnity payable by the concession-granting power.

16

Table of Contents

2. Transmission service concessions, under Concession Contract 006/97 (Cemig), relating to the transmission facilities under Cemig’s responsibility that are classified as part of the National Grid, under Law 9074/95 and related regulations, with provisos relating to authorized revenue, operational conditions and residual value of the assets. The indemnity specified in Mining and Finance Ministry Interministerial Order 580 for the Company’s transmission assets was R$ 285,438,000 (two hundred and eighty five million, four hundred and thirty eight thousand Reais). The annual revenue laid down by Order 579 was R$ 148,536,000.

As specified in the Provisional Measure, Cemig has until December 4, 2012 to state its position on agreement with the tariffs specified in the generation and transmission concessions referred to, and also on the amounts

17

Table of Contents

of the indemnities specified, for the purposes of signing the renewal of the concession contracts. If the Company does not accept the terms laid down by the concession-granting power, it will continue to operate the assets until the end of the period of each one of the concessions referred to.

Since the Company has not yet made its final statement of position on acceptance of the conditions specified in the Provisional Measure for bringing forward renewal of its concessions and its assessment of the indemnity value specified, it is not currently possible to determine the financial effects of the Provisional Measure on its Financial Statements.

Performance of shares

Sources: Economática, Latibex.

Brazil’s main equity index, the Ibovespa, recovered from a strong fall in the prior three months, to close 8.87% higher on the third quarter of 2012. Cemig’s equities traded in Brazil — preferred (CMIG4) and common shares (CMIG3) — fell by 34.91% and 29.56%, respectively, in the quarter. The movement was in the same direction as that of Brazil’s IEEX Electricity Index, which fell 15.04% over the quarter.

The fall in electricity stocks reflected the market’s reaction to the announcement of Provisional Measure 579, which provided for early renewals of concessions under a new tariff regime.

Cemig’s consolidated electricity market

The figures we report for Cemig’s market include the sale of electricity by: Cemig D, Cemig GT consolidated (Cemig GT plus Cachoeirão, Pipoca and the proportionate holdings in the Parajuru, Morgado and Volta do Rio wind farms); the subsidiaries and affiliates (Horizontes, Ipatinga, Sá Carvalho, Barreiro, Cemig PCH, Rosal and Capim Branco); and Light (in proportion to Cemig’s holding).

This equates to: the sales of electricity to both captive and free consumers, in the concession area of Minas Gerais and outside that state; the sales of electricity to other agents of the electricity sector in the Free and Regulated Markets; the sales under the Proinfa Program to Encourage Alternative Electricity Sources; and the sales on the CCEE (the wholesale market) — eliminating transactions between companies of the Cemig group.

The volume of electricity sold to final consumers in Cemig’s concession area in 3Q12 was 3.8% higher than in 3Q11. This reflects the constant increase in Cemig’s total number of clients — to a total of 11.5 million consumers at the end of 3Q12, 1.0% more than at the end of 3Q11. Of this total number of consumers, Cemig D serves 7.5 million, and Light serves 4.0 million; Cemig GT has 367 clients; and the subsidiary and affiliate companies have 22 clients.

This growth can be seen in detail in the separate consumer categories:

22

Table of Contents

Residential:

Residential consumption represented 17% of the total electricity transacted by Cemig in 3Q12. The growth of 6.1% over the period reflects connection of new consumers, and increased private consumption of goods and services due to the more favorable conditions of the Brazilian consumer market, in turn reflecting the vigorous employment market, and growth in total real wages, associated with expansion of the supply of credit.

Industrial:

Consumption by Free Consumer clients represented 40% of the total volume of electricity transacted by Cemig in 3Q12, and was 0.4% more than in 3Q11. The increase basically reflects the recovery in the level of industrial activity in Cemig’s concession area.

Commercial:

This total volume of electricity transacted with this user group accounted for 11% of Cemig’s total in 3Q12, and was 13.2% more than the volume transacted in 3Q11.  This growth is also associated with the strong domestic consumer market, especially final consumption by private consumers.

Rural:

Rural consumption, representing 5% of total electricity sold by Cemig, was 2% higher than in 3Q11, with first-time connection of 91,605 rural properties in the interval.

23

Table of Contents

Other consumer categories:

The total of other types of consumption in 2012 — by public authorities, public illumination, public services, and Cemig’s own consumption — represented 6% of Cemig’s total transactions in electricity in the quarter, and was 7% higher than in 3Q11.

(*) The information in MWh has not been reviewed by the external auditors.

This chart shows the breakdown of the Cemig Group’s sales to final consumers:

Table of Contents

The electricity market of Cemig GT

The consolidated total of electricity sold by Cemig GT means the total of: sales to Free Clients both in the state of Minas Gerais and outside it; sales under the Proinfa program to encourage new energy sources; and wholesale sales in the Regulated and Free Markets, and through the CCEE (Electricity Trading Chamber).

Cemig GT’s electricity market was 0.69% smaller, in aggregate, in 3Q12, than in 3Q11.  This was due to a lower volume of sales of electricity in the Free Market in the period.

The counterpart to this was that total revenue from electricity supply in 3Q12 was 15.2% higher year-on-year, at R$ 1.3 billion, compared to R$ 1.1 billion in 3Q11, which was a result of the Company’s commercial strategy.

This is mainly due to higher prices in the spot market; but is also due to sales being 2.3% higher year-on-year in the industrial consumer category — and 143.0% higher in the commercial category.

Although the volume of electricity sold to other concession holders was 7.6% lower YoY, revenue from that electricity sold to other concession holders was 19.2% higher, at R$ 453 million in 3Q12, compared to R$ 380 million in 3Q11.

The electricity market of Cemig D

The concession area of Cemig Distribuição S.A. (Cemig D) covers 567,748 km², approximately 97% of the Brazilian State of Minas Gerais.  Cemig D has four electricity distribution concessions in Minas Gerais, under four concession contracts — for the Western, Eastern, Northern and Southern areas of the State. These contracts have expiry date of February 18, 2016, and a clause providing for their extension by the concession-granting power for a further 20 (twenty) years, upon application by the concession holder.

Total sales of electricity by Cemig Distribuição were 0.43% higher in 3Q12 than 3Q11. The main positive contribution to this result comes from the residential, commercial and rural user categories. A negative contribution comes from the Industrial category of Cemig’s captive market, in which consumption was 8.6% lower year-on-year in 3Q12 — before any adjustment for the clients that migrated from the captive market to the Free Market.

The following are some comments on the figures for the main consumer categories:

Residential:

Residential consumption was 35.7% of the total electricity sold by Cemig D in 3Q12, and was 3.1% higher than in 3Q11.

Industrial:

Electricity used by (captive) industrial clients was 16.9% of the volume sold by Cemig D in 3Q12, and totaled 8.6% less than in 3Q11 — the main factor being the migration of captive clients to the status of free clients in 2012.

26

Table of Contents

Commercial and Services:

The volume of electricity sold to this consumer category accounted for 20.8% of the electricity sold by Cemig D in 3Q12, and was 3.0% higher than in 3Q11.

Rural:

Rural consumption was 1.74% higher year-on-year, with the connection of 91,624 new rural properties added in the 12-month period. These consumers accounted for 13.4% of the total electricity consumption.

Other consumer categories:

The total of the other types of consumption in 3Q12 — by public authorities, by public illumination, by public services, and Cemig’s own consumption — was 1.0% higher than in 3Q11, and was 13.3% of the total volume sold by Cemig D.

Consolidated operational revenue

Revenue from supply of electricity

Revenue from total supply of electricity to final consumers in 3Q12 was R$ 4.150 billion, compared to R$ 3.821 billion in 3Q11, an increase of 8.6%.

The main factors affecting revenue in 2012 were:

·                      Tariff increase for Cemig D with average effect on consumer tariffs of 3.85%, starting from April 8, 2012.

·                      Tariff increase for Cemig D with average effect on consumer tariffs of 7.24%, starting from April 8, 2011.

·                      Volume of energy invoiced to final consumers 3.84% higher (this excludes Cemig’s own internal consumption).

·                      Contractual upward indexed adjustment to the prices paid by Free Consumers, the main indexor being the IGP—M inflation index.

28

Table of Contents

Revenue from wholesale electricity sales

Although the volume of electricity sold to other concession holders in 3Q12 was 5.19% lower than in 3Q11, revenue from these sales was 15.87% higher, at R$ 487.7 million (vs. R$ 420.9 million in 3Q11) due to the average sale price being 22.21% higher — at R$ 139.84/MWh, compared to R$ 114.42/MWh in 3Q11.

Revenue from use of electricity distribution systems (TUSD)

The revenue from the TUSD (Tariff for Use of the Distribution System), received by Cemig D and Light, was 5.97% lower in 3Q12, at R$ 527.7 million, compared to R$ 561.2 million in 3Q11. This revenue comes from charges made to Free Consumers on the electricity sold by other agents of the electricity sector.

Transmission concession revenue

Transmission concession revenue in 3Q12 was R$ 548,798, 25.81% more than in 3Q11 (R$ 436,217). This variation mainly reflects the expansion of Cemig GT’s transmission assets arising from the new acquisitions made in 2011 — principally of Abengoa, acquired through Cemig GT’s subsidiary Taesa. The transmission revenue aggregated by Taesa in 3Q12 (stated in proportion to Cemig’s stake) was R$ 318,502, compared to R$ 274,986 in 3Q11.

Transactions in electricity on the CCEE

Revenue from transactions in electricity on the CCEE (Electricity Trading Chamber) in 3Q12 was R$ 69,256, an increase of 37.13% relative to 3Q11,

29

Table of Contents

when it was R$ 50,504). This reflects the significantly higher average spot market price in 3Q12 — of R$ 131.14 — compared to R$ 20.61 in 3Q11.

Other operational revenues

This total includes charged services, supply of gas, sharing of infrastructure, the subsidy for the low-income electricity tariff, and other services provided under the concession.

It was 36.69% higher, at R$ 344,744, in 3Q12 than in 3Q11 (R$ 252,204).  The difference mainly reflects (i) supply of gas 35.62% higher in 3Q12 than in 3Q11; and (ii) the new criteria for the low-income rate subsidy, set by Aneel Resolution 472 of January 2012. Resolution 472 laid down the method for calculating the monthly difference of revenue resulting from application of the Social Electricity Tariff, and the resulting amount of funds to be paid to the distributors to pay for the difference.

Charges applied to revenue

The charges applied to revenue in 3Q12 totaled R$ 1,875,314, an increase of 4.70% compared to 3Q11 (R$ 1,791,149). The main variations in these deductions from revenue between the two years are as follows:

Global Reversion Reserve — RGR

The deduction from revenue for the RGR in 3Q12 was R$ 76,891, 51.53% higher than the figure for 3Q11 (R$ 50,742).  The RGR is charged to providers of public electricity service under concessions and permissions, to provide funds for reversion, compulsory takeover of concessions, and expansion and improvement of service. The annual RGR payments are calculated as 2.5% of the concession holder’s capital expenditure, pro rata tempore per quarter, with a maximum of 3.0% of each concession holder’s total revenue from retail and wholesale supply (except supply originating from Itaipu),

30

Table of Contents

use of the electricity network, and charged services, less the related amounts of ICMS tax embedded in revenue, where applicable.

The Fuel Consumption Account — CCC

The CCC quota in 3Q12 was R$ 114,256, 39.91% less than in 3Q11 (R$ 190,141). This charge is for the costs of operation of the thermal plants in the national grid and in the isolated systems. It is shared between electricity concession holders, on a basis set by an Aneel Resolution.

CDE — Energy Development Account

The payments of the CDE are set by an Aneel Resolution, and were 17.13% higher in 3Q11 than 3Q11. The amount of the CDE charge in the quarter was R$ 151,978, compared to R$ 129,751 in 3Q11.

The other deductions from revenue are taxes, calculated as a percentage of amounts invoiced. Hence their variations are substantially proportional to the changes in revenue.

31

Table of Contents

Operational costs and expenses

(Excluding Financial revenues (expenses))

Operational costs and expenses (excluding Financial revenue/expenses) totaled R$ 3.545 billion in 3Q12, 26.83% more than in 3Q11 (R$ 2.795 billion). This mainly reflects higher costs on employee profit shares, electricity bought for resale, operational reversals, charges for use of the national transmission grid, and gas bought for resale.

The following paragraphs outline the main variations in expenses:

Employees’ and managers’ profit shares

The expense on employees’ and managers’ profit shares in 3Q12 was R$ 59,139, compared to R$ 46,659 in 3Q11, an increase of 26.75%.  The considerable difference reflects recognition in 3Q12 of profit shares previously agreed with the unions for this business year; in 2011 the largest portion was provisioned only in the fourth quarter of the year — since in that year the negotiations were completed in December.

Electricity bought for resale

The expense on electricity bought for resale in 3Q12 was R$ 1,580,014 — 42.24% more than in 3Q11 (R$ 1,110,782). This primarily reflects:

·                      Financial exposure of Cemig D to the spot market 114.34% higher — R$ 208,634 in 3Q12, compared to R$ 97,339 in 3Q11, due to considerably higher average spot market prices in all the sub-markets — these averaged R$ 20.61/MWh in 3Q11, and R$ 131.14/MWh in 3Q12.

32

Table of Contents

Financial revenues (expenses)

Net financial expenses in 3Q12 were 11.99% lower than in 3Q11 — at R$ 239,287, vs. R$ 271,886 a year before.

The main factors in the difference between 2Q12 and 2Q11 are

·                      Revenue from late charges on overdue electricity bills in 3Q12, at R$ 49.019, was 61.59% higher than in 3Q11 (R$ 30,336). Among other factors, this reflects implementation of collection follow-up by e-mail and text message, with more effort applied also to standard methods such as follow-up letters and formal demands.

·                      Revenue from cash investments was 29.72% lower — on less cash invested in 2012.

·                      Lower expense on costs of loans and financings, at R$ 298,955 in 3Q12, compared to R$ 357,496 in 3Q11. This basically reflects a lower volume of loans linked to the CDI rate in 3Q12 than in 3Q11, and also the lower variation represented by applying the CDI rate in the quarter.  In 3Q12 this variation was 1.91%, compared to 3.01% in 3Q11.

·                      Expense on monetary updating of loans and financing 199.67% higher, at R$ 48,049, in 3Q12 than in 3Q11 (R$ 16,034). This reflects the higher value of the IGP—M inflation index in the third quarter of 2012 than in 3Q11, and also the effect of new capital raised as from 2Q11.

·                      Expense of monetary updating on paid concessions: a total of R$ 17,086 in 3Q12, compared to R$ 4,135 in 3Q11. This reflects the significantly higher variation in the IGP—M inflation index in 3Q12 — which was 0.97% in 3Q11, but 3.78% in 3Q12.

Ebitda

The higher Ebitda in 3Q12 than in 3Q11 primarily reflects net revenue 17.63% higher, mainly due to the gain on issue of shares referred to above, and revenue 19.19% higher, partially offset by operational costs and expenses (excluding effects of depreciation and amortization) 30.22% higher. The higher Operational costs and expenses in 3Q12 than 3Q11 are reflected in Ebitda margin, which was 36.90% in 3Q11, and 36.42% in 3Q12.
