MARKET ANNOUNCEMENT

Aneel announces result of Tariff Review of Cemig D

Cemig (Companhia Energética de Minas Gerais), a listed company with securities traded on the stock exchanges of São Paulo, New York and Madrid, in accordance with CVM Instruction 358 of January 3, 2002, as amended, hereby publicly informs the Brazilian Securities Commission (CVM), the São Paulo Stock, Commodities and Futures Exchange (BM&F Bovespa S.A.) and the market in general, as follows:

At its public meeting held today the Brazilian electricity sector regulator, Aneel (Agência Nacional de Energia Elétrica), published the results of the Third Tariff Review, which will result in positive repositioning of the tariffs of Cemig Distribuição S.A.

These tariffs will take effect as from April, 2013. The average effect for consumers will be an increase of 2.99%. This effect comprises one part reflecting the revision per se, and one part comprising the associated financial components.

In this decision, Aneel is applying the effects of Decree 7945/12, which governs the use of the funds from the Energy Development Account (Conta de Desenvolvimento Energético, or CDE) to attenuate distributors’ costs of acquisition of electricity in the Electricity Trading Chamber (Câmara de Comercialização de Energia Elétrica, or CCEE) as a result of the unfavorable hydrological conditions, which have led to the dispatching of thermal generation plants.

The Decree aims to reduce the impact of the adjustment. For Cemig D, it limits the adjustment to 3%. The amount that exceeds this percentage will be passed through in a single payment, within 10 business days from the date of publication of the Homologating Resolution confirming this review. The amount of these funds, coming from the CDE, will be decided by Aneel within this period, and will be reimbursed by consumers over 5 years, updated by the IPCA inflation index.

It is noted that the application of the adjustment will not be uniform for all types of consumer, and that consumers’ tariffs will also be affected by the new tariff structure, which is a sub-process of the Tariff Review. Another item established in the Review process is the multiple known as the “X Factor”, which contains the XPd Factor (representing productivity) and the XT (for transition) Factor. These have been calculated to be 1.15% and 0.68%, respectively.

According to the statement of calculation received by Cemig after the homologation of the result of the Tariff Review by the meeting of the Council of Aneel, the Net Regulatory Remuneration Base was R$ 5,511,767,731.07, and the Gross Regulatory Remuneration Base was R$ 15,355,842,946.29.

PROPOSAL

BY THE BOARD OF DIRECTORS TO THE

EXTRAORDINARY GENERAL MEETING OF STOCKHOLDERS

TO BE HELD ON MAY 23, 2013.

Dear Stockholders:

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

— whereas:

a) Cemig’s long-term strategic plan contains the long-term strategic planning, fundamentals, targets, objectives and results to be pursued and achieved by the Company, and its dividend policy, and it is the responsibility of the Board of Directors and of the Executive Board faithfully to obey and comply with the targets established in § 7 of Article 11 of the by-laws, notably the target limiting the consolidated amount of funds allocated to capital investment and acquisition of any assets, in a business year, to the equivalent of a maximum of 40% (forty per cent) of the Company’s Ebitda (profit before interest, taxes, depreciation and amortization);

b) the opportunities and needs for investments that became available to the Cemig Group led to a volume of investments in 2012 equivalent to 54% of Ebitda, thus higher than the target limit mentioned in subclause ‘a’ above;

b) exceeding of the limit arose principally from the increase in the Company’s Program of Investments in 2012, among which highlights are:

· acquisition of a stockholding in Unisa — União de Transmissoras de Energia Elétrica Holding S.A by Transmissora Aliança de Energia Elétrica S.A. — Taesa;

· acquisition by Cemig of a stockholding in Companhia de Gás de Minas Gerais — Gasmig;

· updating of and improvements to the generation equipment and transmission system of Cemig Geração e Transmissão S.A., and, further,

· the Distribution Development Plan (PDD) of Cemig Distribuição S.A.;

— now proposes to you as follows:

Ratification of the Company having, in 2012, exceeded the limits specified in subclause “d” of Paragraph 7 of Article 11 of the by-laws, corresponding to: the consolidated amount of funds destined to capital expenditure and acquisition of any assets of the Company being equivalent to a maximum of 54% (fifty four per cent) of the Company’s Ebitda (Earnings before interest, taxes, depreciation and amortization).

As can be seen, the objective of this proposal is to meet legitimate interests of the stockholders and of the Company, and as a result it is the hope of the Board of Directors that you, the stockholders, will approve it.

Belo Horizonte, April 11, 2013.

Comments by the directors on the Company’s financial situation, required by Item 10 of the Reference Form, in compliance with Article 9, III of CVM Instruction 481 of December 17, 2009.

10.1 General conditions of finances, assets and liabilities

The Company’s Chief Officers see the year 2012 as one of great changes, complexity and challenges. They believe that the quest for operational efficiency and the discipline of investing in assets that add value certainly contributed significantly to the growth due to the expansion of the various companies in which Cemig holds a significant equity interest and participates significantly in management.

In this context, the results that Cemig achieved in 2012 are of considerable repercussion due to their scale: net profit totaled R$ 4.3 billion, or R$ 5.37 per share, representing a price/earnings ratio of 4. Net profit was almost 80% higher than in the previous year.

The greatest impact came from the early settlement of the CRC Contract (the Contract to Assign the balance of Credit Receivable by the Company under the former CRC — Earnings Compensation — Account with the Brazilian federal government). The State of Minas Gerais, the majority stockholder, decided to bring forward the payment of this contract, which generated a financial gain of more than R$ 2 billion.

The Chief Officers highlight another important event of the year: the share offering by Taesa, which received enormous acceptance by investors and resulted in a significant gain for Taesa —giving rise to a gain of R$ 259 million in Cemig GT’s results. This successful offering, carried out in market conditions that were considered to be unfavorable, is a clear demonstration of investors’ confidence in the Company’s strategies. Taesa is Cemig’s preferred vehicle for operating its investments in the area of electricity transmission.

The Brazilian capital market once again showed its capacity to finance significant volumes, providing more than R$ 7 billion funding for various companies of the Group.

In the Chief Officers’ opinion, the company has adequate liquidity, in view of its cash position of R$ 2.486 billion on December 31, 2012. The cash position was R$ 2.862 billion on December 31, 2011, and R$ 2.980 billion on December 31, 2010.

The Chief Officers believe that the Company has a balanced capital structure. On December 31, 2012 this was represented by indebtedness of R$ 16.2 billion, 44% of this amount comprising short-term debt and 56% long-term debt. This concentration in the short term arose from recognition of 7% of the debt (26% of the debt of Cemig Distribuição S.A.) in current liabilities, due to not having obtained, before the reporting date, the formal waiver from creditors that they would not exercise their rights of demanding immediate or early maturity of debt due to non-compliance with a covenant. The company expects to obtain the consents, but since this will take place after December 31, 2012, the contract is of which the covenants were not complied with are recognized in Current liabilities. The amount transferred to Current liabilities as a result of the covenant clauses not complied with was R$ 1.206 billion. On December 31, 2011, the Company’s capital structure comprised indebtedness of R$ 15.8 billion, of which 50% was short-term debt and 50% was long-term debt. In that year, the concentration in the short term arose from recognition of 12% of the debt (23% of the debt of Cemig Geração e Transmissão S.A.) in current liabilities, due to not having obtained, before the reporting date, the formal waiver from creditors that they would not exercise their rights of demanding immediate or early maturity of debt due to non-compliance with a covenant (the waiver was obtained on March 14, 2012). On December 31, 2010, the Company’s capital

43

Table of Contents

structure comprised indebtedness of R$ 13.2 billion, of which 17% was short-term and 83% was long-term.

At December 31, 2012 the amortization timetable of the Company’s debt was satisfactorily spread out over the years, with an average tenor of 3.9 years, although there is a concentration of debt maturing in 2013, as shown in the chart below, which has been partially refinanced in March 2013, through an issue of debentures by Cemig Distribuição. In the other years, the payments are of up to R$ 2.4 billion, approximately, reflecting the efforts made by the Company to lengthen its debt profile.

44

Table of Contents

the debt in contracts indexed to the DI Interbank Deposit (CDI) rate. The main indexors of the Company’s debt on December 31, 2012 were: CDI (47% of the total); IPCA (24% of the total); and URTJ (13% of total). The debt ratios in the table below indicate the Company’s satisfactory credit quality, highlighting its very comfortable position in relation to the parameters usually practiced in the financial market for those indicators:

|  |  |  | December 31, |
|  | 2012 |  | 2011 |  | 2010 |
Ebitda / Interest |  | 3.84 |  | 4.08 |  | 4.22 |
Net debt / Ebitda |  | 2.73 |  | 2.41 |  | 2.26 |
Net debt / (Stockholders’ equity + Net debt) |  | 54 | % | 52 | % | 47 | %
Source: Company. |  |  |  |  |  |  |

b. Capital structure and possibility of redemption of shares or share units, indicating:

The pattern of financing of the Company’s operations by its own and third-party capital can be seen, over the years, in the average leverage in terms of the ratio between debt and capitalization (Stockholders’ equity plus net debt). On December 31, 2012 the Company’s stockholders’ equity was R$ 12.044 billion, while net debt was R$ 30.896 billion.

On December 31, 2011, stockholders’ equity was R$ 11.745 billion and net debt was R$ 12.917 billion; and on December 31, 2011, these figures were respectively R$ 11.476 billion and R$ 10.247 billion.

In the Chief Officers’ opinion the ratio of net debt to the sum of stockholders equity and net debt has been at appropriate levels, namely: 54% on December 31, 2012, 52% on December 31, 2011 and 47% on December 31, 2010.

Possible situations of redemption

Formula for calculation of the redemption value

There are no specific possibilities for redemption of the shares issued by the company, beyond those normally specified by law.

c. Payment capacity in relation to the financial commitments assumed

The Chief Officers highlight the Company’s cash generation capacity. In 2012 operational activities generated the substantial sum of R$ 2.734 billion in cash. In the two previous years: cash generated in 2011 was R$ 3.898 billion, and in 2010, R$ 3.376 billion.

The cash position was R$ 2.486 billion on December 31, 2012, R$ 2.862 billion on December 31, 2011, and R$ 2.980 billion on December 31, 2010.

By comparison net debt was R$ 13.896 billion on December 31, 2012, R$ 12.917 billion on December 31, 2011, and R$ 10.247 billion on December 31, 2010. The ratios for 2012 and 2011 indicate that approximately 2.5 years’ operational cash flow (Ebitda) would be sufficient to settle the debtor balance and indicator of 2010 indicates that approximately 2 years’ Ebitda would be sufficient to settle the debtor balance. These indices provide comfort to Management and investors in relation to the Company’s capacity to honor its financial commitments.

In the Chief Officers’ view, the total debt is very satisfactorily spread out over the years, although there is a concentration of debt becoming due in 2013, which does not represent refinancing risk. It should be pointed out that the Company has been successful in accessing the capital markets, both to

45

Table of Contents

finance its investments and to refinance its debt. The following issues of securities are examples of this:

Third issue of non-convertible debentures, on February 15, 2010, in the amount of R$ 1.350 billion, for rollover of the third issue of Promissory Notes and replenishment of working capital.

Current liabilities were R$ 14.307 billion on December 31, 2012, R$ 12.169 billion on December 31, 2011, and R$ 6.403 billion on December 31, 2010. The principal obligations are for loans, financings, suppliers, taxes, dividends and regulatory charges.

Thus, the Chief Officers believe that the Company has high payment capacity in relation to its financial commitments, maintaining its track record of complying with its financial commitments assumed to suppliers, government, stockholders and employees and also ensuring funding for its investments and future acquisitions.

d. Sources of financing used for working capital and investment in non-current assets

On a consolidated basis, the total of funding obtained through loans and financings in 2012 was R$ 7.075 billion, while the total amortized was R$ 6.827 billion.

At the end of the year, Cemig contracted a short term loan in the amount of R$ 1.088 billion for redemption of the Fourth Issue of promissory notes.

In 2012, Cemig D (Cemig Distribuição) raised R$ 1.470 billion, as follows: R$ 200 million through a Bank Credit Note with Banco do Brasil for refinancing existing debt; R$ 1.240 billion through two issues of commercial promissory notes to finance investments, pay debt and replenish working capital; and R$ 34 million in financings from Eletrobras for the Reluz, Cresce Minas and Luz para Todos Programs. Also, the Company received R$ 175 million from the CDE (Energy Development Fund) and from the State of Minas Gerais, on a sinking-fund basis, for the Light for Everyone Program; and the economic subsidy/support related to the tariff policy applicable to low-income consumers with the funds of Codemig for the Administrative Center.

Cemig GT extended the maturity of part of its debt through renewal of lending transactions with Banco do Brasil, as follows:

a) transactions contracted in 2006 with final maturity after 2012: extension of the 2012 maturity portion to 2013, in the global amount of R$ 300 million, the other maturities being unchanged, for financial cost of 104.1% of the CDI rate;

b) operations with final maturity in 2012, in the total amount of R$ 442 million, extending the maturity of the last installment by five years, with payments in 2015, 2016 and 2017: the cost of this debt is 108% of the CDI, from the date of signature of the amendments to the contracts.

In both transactions the Cemig holding company remained as guarantor, and Cemig D and GT maintained the option to pre-pay the debt without additional cost.

In March 2012, Cemig GT completed its 3rd debenture issue — a total of 1,350,000 non-convertible, unsecured debentures in 3 series, each with nominal unit value of R$ 1,000.00 (one thousand Reais) on the issue date (February 15, 2012), for a total of R$ 1.35 billion. The net proceeds from the issue were used for 100% redemption of the commercial Promissory Notes of the Company’s fourth issue, placed on January 13, 2012, for their total nominal value of R$ 1,000,000, plus remuneratory interest, and to strengthen the Company’s working capital. Four hundred eighty thousand (480,000) Debentures of the First Series, 200,000 (two hundred thousand) Debentures of the Second Series and 670,000 (six hundred seventy thousand) Debentures of the Third Series were issued, with maturities, respectively, of five, seven and 10 years from the issue date. The debentures of the first series carry

47

Table of Contents

remuneratory interest at the rate of CDI + 0.90% p.a., and the debentures of the second and third series will have their nominal unit value adjusted by the IPCA index (published by the IBGE) plus remuneratory interest of 6.00% p.a. and 6.20% p.a., respectively. This third public issue of non-convertible debentures has the surety guarantee of the parent company, Cemig, and was the first debenture issue to be held in the ambit of the Fixed Income Novo Mercado regulated by Anbima, the Brazilian Association of Financial and Capital Market Entities.

In 2011, to replenish cash used in investments in 2011, and to finance an acquisition of assets planned for the first half of 2012, Cemig issued Promissory Notes in the amount of R$ 1 billion with tenor of 360 days, confirming the receptiveness that the Company enjoys in the local capital market.

Cemig D also had recourse to the capital market at the end of 2011, issuing R$ 100 million in Promissory Notes for strengthening of working capital. Over the year, a further R$ 410 million was raised in loans, and a further R$ 116 million in financings from Eletrobrás for the Reluz, Cresce Minas and Light for Everyone (Luz para Todos) Programs. Also, the Company received R$ 291 million from the CDE (Energy Development Fund) and the State of Minas Gerais on a sinking-fund basis for the Light for Everyone Program, and in economic subsidy/support related to the tariff policy applicable to low-income consumers with the funds of Codemig, for the Administrative Center.

Cemig GT, meanwhile, took the opportunity of its comfortable cash position to pay its debt servicing, in the amount of R$ 1.219 billion (R$ 689 million being principal), practically without having recourse to new raising of funds, as a way of optimizing its leverage. However, on a consolidated view, the indebtedness of the Company includes the effect of the financings contracted by its subsidiaries to pay for investments in generation, principally the Santo Antônio Hydroelectric Plant and the Belo Monte Hydroelectric Plant, and in transmission, in which a highlight was the Promissory Notes of Taesa, in the amount of R$ 1.17 billion (affecting the indebtedness of Cemig GT in the amount of R$ 663 million), for acquisition of the assets of Abengoa.

In 2010, a total of R$ 904 million was raised by Cemig D: R$ 370 million through loans guaranteed by electricity sale invoices, R$ 279 million through rollover of bank debt; R$ 66 million through financings from Eletrobrás for the Reluz, Cresce Minas and Luz para Todos Programs, and R$ 189 million on a sinking fund basis under the Light for Everyone Program (funds from the CDE), from the agreements for the Citrus-growing Center (Polo de Citricultura) and Planoroeste plans, and from the economic subsidy related to the tariff policy applicable to low-income consumers.

Non-consolidated, R$ 2.949 billion was raised by Cemig GT individually, of which R$ 2.700 billion was a debenture issue for settlement of the Promissory Notes in the same amount used in the acquisition of the shares of Terna Participações S.A. and other investments, R$ 242 million through rollover of bank debts and R$ 7 million through contracts signed with Finep for plant inventory studies. A consolidated view of Cemig GT includes the contracting of approximately R$ 1.061 billion in financings by its subsidiaries and affiliates (this being the amount proportional to the stockholding interest of Cemig GT).

The holding company, Cemig, also raised R$ 350 million in the capital market with its third issue of Promissory Notes, with tenor of 360 days, using the funds for replenishment of its cash at the end of the year.

e. Sources of financing for working capital and investment in non-current assets that it is intended to use for coverage of shortfalls in liquidity

48

Table of Contents

It should be borne in mind that Cemig D is a wholly-owned subsidiary of Cemig, which is a mixed private- and public-sector company, with a majority stockholding held by the State of Minas Gerais, and as such is subject to the rules for containment of lending to the public sector.

Since 1989, in the attempt to contain the indebtedness of the public sector, the Brazilian federal government has legislated to prevent financial institutions from granting credit to public companies beyond a certain limit. In practice, the alternatives for raising funds in the banking market are few.

Based on the exceptions in Brazilian Central Bank Resolution 2827 of March 30, 2001, the following options for raising of funds remain for Cemig:

Loans from federal banks for rollover of debt.

Issuance of securities in the Brazilian and international markets (debentures, promissory notes, Eurobonds, and units of receivables funds).

Import financing.

Financing from development agencies.

Bank loans guaranteed by commercial sales invoices.

Guidelines for raising of funding from third parties

The Company’s Chief Officers believe that the importance of loans and financings for the Company’s capital structure is in the direct effects of financial leverage, which tends to maximize return on equity. Due to the possibility of deducting the interest expense for the purposes of tax, loans and financings are very desirable in the Company’s capital structure, reducing the cost of capital. Further, they give the Company access to a wider selection of acceptable investment alternatives.

The process of raising third-party funds, because of its importance for maximizing wealth of the stockholder and because of the direct impact on the Company’s capital structure and its financial health, is guided by a series of guidelines that are able to preserve the Company’s credit quality.

For this purpose, we obey the following orientations:

Take advantage of favorable market conditions. Moments of high liquidity in the debt markets, which offer abundant and cheaper funds, should be taken advantage of to leverage the expansion of the Company’s activities, making a greater number of projects with attractive returns possible.

Keep the debt amortization timetable lengthened. Avoid concentration of debt maturing in the short term, because it represents pressure on the Company’s cash flow, compromising availability of funds for investment. A regular amortization timetable over the long term must be an aim. However, in certain situations the longest possible tenor may not be the ideal ones, since it is occasionally associated with a higher financial cost.

Reduce financial cost. Reduction of the average cost of the debt should be sought at all times, because it is a fundamental part of the Company’s weighted average cost of capital, which, along with the stockholders’ expectation of returns, is the minimum reference for return on the investments being considered for implementation.

Optimize the exposure to foreign currency. Efforts should be made to optimize the composition of the debt in relation to the indexors of the Company’s assets. Cemig, because it has its remuneration basically linked to the IGP-M inflation index, should place the greatest tranche of the composition of its debt in this indexor. However, the international debt market is the one with the greatest liquidity, and funds in foreign currency are welcome, provided that the part that does not have any hedge protection does not represent a material financial risk for the Company.

Maintain coherence with Cemig’s Long-term Strategic Plan. Cemig has, in its Bylaws, the express obligation to limit certain financial indicators to levels that denote its financial health. These limits were defined as part of Cemig’s long-term Strategic Plan, as a means of ensuring to stockholders that investments for expansion of the Company will be carried out in a way that preserves its sustainability. These include limitation of: Debt/Ebitda, to less than or equal to 2; and [Net debt / (Stockholders’ Equity + Net Debt)], to less than or equal to 40%. The Company makes efforts to maintain the indicators within these limits.

Maintain adherence to the parameters of credit quality of the regulatory body, the rating agencies and the creditors. The Company’s Chief Officers believe that the market’s perceptions of risk are important since they define parameters for attesting to the Company’s credit quality and serve as guidelines for its decision on interest rates to be required in making loans/financings. Often, loan or financing contracts include restrictive covenants imposed by the creditors for their protection, which give the creditors the right to break the lending agreement and require immediate reimbursement of the funds when the Company’s financial position appears to be weakened. The Company’s credit quality should thus be preserved at levels that denote “investment grade”, that is to say investment of low risk, to enable it to benefit from financial costs that are compatible with the profitability of the business. The body that regulates the Company’s activities, the National Electricity Agency (Agência Nacional de Eletricidade, or Aneel), also defines an optimal capital structure which is used in calculation of the remuneration of a company’s base of regulatory assets, in the transmission sector.

f) Levels of debt and the characteristics of such debts

On December 31, 2012, the company’s consolidated debt in financial contracts was R$ 16.2 billion; and its net debt was R$ 13.9 billion. On December 31, 2011, the Company’s consolidated debt under financial contracts was R$ 15.8 billion, and the net debt on that date was R$ 12.9 billion. On December 31, 2010 these balances were, respectively, R$ 13.2 billion for consolidated debt and R$ 10.2 billion for net debt.

The indicators in the table below show the Company’s credit quality to be satisfactory. The increase in debt from 2009 to 2010 was due to the financing of the process of acquisition of assets:

|  |  |  | December 31, |
|  | 2012 |  | 2011 |  | 2010 |
Indebtedness of Stockholders equity |  | 2.39 |  | 2.18 |  | 1.92 |
Net debt / Ebitda |  | 2.73 |  | 2.41 |  | 2.26 |
Net debt / (Stockholders’ equity + Net debt) |  | 54 | % | 52 | % | 47 | %

Final consumers

Revenue from sales of electricity to final consumers (excluding Cemig’s own consumption) was R$ 16.671 bn in 2012, 11.47% more than in 2011 (R$ 14.955 bn).

The main factors in this result are:

Volume of energy invoiced to final consumers (excluding Cemig’s own consumption) 4.49% higher.

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

Price adjustments in contracts for sale of electricity to free consumers, most of which are indexed to the IGP—M inflation index.

Evolution of the market

Cemig’s market can be summarized as: 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); with elimination of transactions between companies of the Cemig group.

The table below shows Cemig’s market in detail, comparing the transactions in 2012 with those of 2011.

( * ) The MWh column includes a percentage of the total electricity sold by Light equivalent to the Company’s stockholding. (Data not reviewed by external auditors.)

( ** ) Includes Contracts for Sale of Electricity in the Regulated Market (CCEARs), and ‘bilateral contracts’ with other agents.

The total of electricity sold by Cemig in 2012 was 2.59% greater than in 2011.

The volume of electricity sold to final consumers was 4.49% higher, due to the expansion of the internal and external market, in spite of the relative slowdown in growth of Brazilian economic activity in 2012.

The following are descriptions of the performance of the main electricity consumer categories:

Residential: Residential consumption was 7.23% higher than in 2011. The growth in consumption by this consumer group mainly reflects connection of new consumers, and increased private consumption of goods and services.

Industrial: Consumption by captive and free clients was 0.23% lower in 2012, basically reflecting reduction in the level of economic activity in the year, the sectors most affected being steel, chemicals and ferro-alloys.

Commercial: Electricity transacted with captive and free clients in the concession area in Minas Gerais and outside the state was 13.81% higher, associated with the strong level of domestic demand, with high growth in retailing, communications services and food.

Rural: Rural consumption grew by 8.61%. This is related to first-time connection of rural properties, and the increase in demand for electricity for irrigation, related to the atypical climatic conditions in 2012.

Other consumer categories: The total of consumption by the other consumption categories — public authorities, public illumination, public services, and Cemig’s own consumption — was 8.87% higher in 2012.

Revenue from wholesale electricity sales

Although the volume of electricity sold to other agents of the electricity sector was 4.08% lower in 2012. The reduction in sales to other agents arises from the Company’s commercial strategy, which gave priority to serving final users (Free Consumers and consumers of incentive-bearing electricity supply) and participation in the wholesale markets subject to the existence of the group’s own available energy, addition of value and minimization of risks.

Although the volume of electricity sold to other concession holders was 4.08% lower, revenue from these sales was 20.67% higher, at R$ 1,903 mn in 2012 (vs. R$ 1,577,000 in 2011) due to the

62

Table of Contents

average sale price being 25.80% higher — at R$ 137.23/MWh in 2012, compared to R$ 109.08/MWh in 2011.

Revenue from use of the electricity distribution systems (TUSD)

The revenue of Cemig D and Light from the Tariff for Use of the Distribution Systems (TUSD) was 11.99% higher, at R$ 2.215bn, in 2012, than in 2011 (R$ 1.978bn). This revenue comes from charges made to Free Consumers on energy sold by other agents of the electricity sector, and its increase arises from a higher volume of transport of energy for free consumers, a consequence of the recovery of industrial activity and of migration of captive clients to the free market.

Transmission Concession Revenue and Indemnity Revenue

Revenue from the Transmission Concession in 2012 was R$ 1.675 billion, vs. R$ 1.407 billion in 2011, an increase of 19.05%. This variation mainly reflects the increase in the Company’s transmission assets arising from the new acquisitions made in the second half of 2011 — principally of Abengoa, acquired through Cemig’s jointly-controlled subsidiary Taesa. The transmission revenue added by Taesa, in proportion to Cemig’s stake, was R$ 696 mn in 2012, compared to R$ 564 mn in 2011.

In 2012 the Company posted an estimated gain reflecting the indemnity of the transmission assets which were included in the criteria of Provisional Measure 579, in the amount of R$ 192mn For more details, please see Explanatory Note 4.

Other operational revenues

Sector / regulatory charges: deducted from operational revenue

The charges applied to operational revenue in 2012 totaled R$ 7,618bn, compared to R$ 6,997bn in 2011, an increase of 8.88%. The main variations in these deductions from revenue between the two years are as follows:

The Fuel Consumption Account — CCC

Expenses on the CCC in 2012 were R$ 565 million, 21.31% more than their total of R$ 718 million in 2011. This charge is for the costs of operation of the thermal plants in the national grid and in the

63

Table of Contents

isolated systems. It is prorated between electricity concession holders, on a basis set by a Resolution issued by the regulator, Aneel.

This is a non-controllable cost: in the distribution activity, the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment. For the portion relating to transmission services, the Company charges the CCC amount to Free Consumers on their invoices and passes it on to Eletrobrás. The variation in this cost is primarily due to reduction in the unit cost of the CCC, which is defined by an Aneel Resolution.

CDE — Energy Development Account

Expenses on the CDE in 2012 were R$ 616mn, 19.38% more than their total of R$ 516mn in 2011. These payments are specified by a Resolution issued by the regulator, Aneel.

This is a non-controllable cost: in the distribution activity, the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment. For the portion relating to transmission services the Company merely charges the CDE amount to Free Consumers on their invoices for use of the grid, and passes it on to Eletrobrás.

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.

For a breakdown of the taxes applicable to revenues, please see Explanatory Note 24 to the consolidated financial statements.

Operational costs and expenses (excluding Financial revenue/expenses)

Operational costs and expenses (excluding Financial revenue (expenses)) totaled R$ 14,639bn in 2012, 27.91% more than in 2011 (R$ 11,445bn). See the principal expenses and costs in Explanatory Note 25 to the consolidated financial statements.

The following paragraphs outline the main variations in expenses:

Electricity bought for resale

The expense on electricity bought for resale in 2012 was R$ 5.951 million, 39.11% higher than the figure of R$ 4.278 million for 2011. This primarily reflects:

Financial exposure to the spot market 164.09% higher in 2012, at R$ 890mn, than in 2011 (R$ 337mn), due to the increase in the average spot price (PLD) between the two periods, in the principal exposure sub-markets, the Southeast and Center-West: this average price was R$ 29.42/MWh in 2011, and for 2012 it had increased to R$ 166.69/MWh.

Purchases of electricity in the Regulated Market 42.80% higher, at R$ 2.806bn in 2012, compared to R$ 1.965bn in 2011. This increase substantially arises from connection of thermal plants in 2012, with a higher cost, and the transfer of this increase in cost to the distributors.

Cemig D’s expense on electricity from Itaipu was 16.32% higher. This supply is indexed to the dollar, and totaled R$ 1.069bn in 2012, compared to R$ 919bn in 2011 — mainly reflecting depreciation of the Real against the dollar in 2012, whereas in 2011 the Real appreciated against the

64

Table of Contents

dollar. The average value of the dollar applied to invoices in 2012 was R$ 1.998, 19.21% higher than the value of R$ 1.676 applied in 2011.

This is a non-controllable cost: in the distribution activity, the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment.

Charges for use of the transmission grid

The expense on charges for use of the transmission network in 2012 was R$ 1.011bn, vs. R$ 830mn in 2011, an increase of 21.81%. This expense refers to the charges, set by an Aneel Resolution, payable by electricity distribution and generation agents for use of the facilities that are components of the national grid.

This is a non-controllable cost: the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment.

Depreciation and amortization

Depreciation and amortization was 1.83% higher year-on-year: R$ 1.001bn in 2012, compared to R$ 983bn in 2011. This basically reflects increase in the assets of the concession due to the program of investments, mainly in distribution, offsetting the effect of the reduction in the rate of depreciation and amortization applied as from 2012 due to the revision of the figures for useful life.

Employee post-retirement liabilities

The expense on post-employment obligations in 2012 was R$ 134mn, compared to R$ 124 million in 2011, an increase of 8.06%. This expense represents the updating of the obligation, calculated in accordance with an actuarial opinion prepared by external consultants.

Personnel

Total personnel expenses in 2012 were R$ 1.361mn, 8.97% more than in 2011 (R$ 1.247bn). This principally reflects the salary increases in November 2011 and 2013, averaging 8.20% and 4.5% respectively, partly offset by the reduction of 3.84% in the number of employees.

Operational provisions

Operational provisions in 2012 totaled R$ 782mn, 203.10% more than in 2011 (R$ 258mn). The main elements in the higher figure are:

Provision of R$159 million for doubtful receivables in 2012 made by Cemig D for the loss in relation to ICMS tax on the Charges for Use of the Distribution System (TUSD) , reflecting non-expectation of receipt of these amounts.

Provision of R$ 403 million for the Settlement Agreement between Cemig and the federal government in relation to the now-extinct CRC Account, which was an operational condition for the early settlement of the CRC contract by the government of Minas Gerais State.

For more details please see Explanatory Note 25 to the consolidated financial statements.

65

Table of Contents

Gas purchased for resale

Expenses on gas bought for resale in 2012 were R$ 495mn, 50.46% more than their total of R$ 329mn in 2011. This reflects the increase in the volume of gas purchased, to meet the requirements of higher sales of gas by Gasmig in 2012, due to increased industrial activity leading to increased consumption by clients in the ‘Steel Valley’ (Vale do Aço) and South of Minas (Sul de Minas) regions.

Outsourced services

The expense on outsourced services in 2012 was R$ 1.127bn, compared to R$ 1.031 million in 2011, an increase of 9.31%. The main variations arise from higher volume of services of communication, maintenance, conservation and cleaning. A detailed breakdown of outsourced services is given in Explanatory Note 25 to the consolidated financial statements.

Net financial revenue (expenses)

The company posted net financial revenue, of R$ 1.252 billion in 2012, compared to net financial expenses, of R$ 970 million in 2011. The main factors in this financial result are:

Revenue from cash investments 27.80% lower, due to a lower volume of cash invested in 2012.

Revenue from monetary updating on the CRC Contract of R$ 2.383 billion, arising from its early settlement, as per fuller details given in Explanatory Note 12.

Revenue from Late Payment Charges on electricity bills 18.54% higher, at R$ 179 million in 2012, compared to R$ 151 million in 2011, resulting from improvement of the process of collection and negotiation of these debits.

Increase in revenue arising from foreign exchange variations: R$ 44 million in 2012 compared to R$ 20 million in 2011, due mainly to the results of cash investments in foreign currency by Taesa.

Increase in foreign exchange variation expense: This expense totaled R$ 82 million in 2012, compared to R$ 40mm in 2011, mainly due to FX variations on loan contracts expressed in US dollars assumed by Taesa as a result of the acquisition of Abengoa.

For a breakdown of financial revenues and expenses, please see Explanatory Note 26 to the consolidated financial statements.

Income tax and Social Contribution tax

In 2012, Cemig’s expenses on income tax and the Social Contribution totaled R$ 1.063 million, on profit of R$ 5.335 million before tax, a percentage of 19.93%. In 2011, Cemig GT’s expenses on income tax and the Social Contribution totaled R$ 918 million, on profit of R$ 3.333 billion before tax, a percentage of 27.54%. These effective rates are reconciled with the nominal rates in Explanatory Note 10 to the consolidated financial statements.

Net operational revenue |  | 15,749 |  | 13,847 |  | 13.74 |

Revenue from supply of electricity

Revenue from total supply of electricity in 2011 was R$ 16.837 billion, compared to R$ 14.821 billion in 2010 — an increase of 13.60%.

Final consumers

Revenue from sales of electricity to final consumers (excluding Cemig’s own consumption) was R$ 14.955 bn in 2011, 13.13% more than in 2010 (R$ 13.219 bn).

The main factors in this result are:

Volume of energy invoiced to final consumers (excluding Cemig’s own consumption) 6.95% higher. Tariff increases for Cemig D, with average effects on consumer tariffs of 1.67% and 7.24%, effective from April 8 of 2010 and 2011, respectively.

Tariff increases for Light, with average effects on consumer tariffs of 2.20% and 7.82%, from November 7, 2010 and 2011, respectively.

Price adjustments in contracts for sale of electricity to free consumers, most of which are indexed to the IGP—M inflation index.

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

Residential:

Residential consumption accounted for 15.3% of the total of electricity sold in 2011. The increase of 8.0% in the total amount in the year reflects connection of new consumer units, and also higher private consumption of goods and services due to the favorable conditions of the Brazilian economy, with continuing vigor in the employment market, growth in total real wages, and expansion of the supply of credit.

Industrial:

Electricity used by free and captive clients was 37.1% of the volume transacted in 2011, 4.8% more than in 2010, due to the expansion of industrial activity with the growth of exports and production to meet domestic demand, in spite of the signals of slowing growth in the second half of the year.

67

Table of Contents

Commercial:

This category consumed 10.0% of the electricity transacted, totaling 12.2% more in volume than in 2011, reflecting the increased level of domestic demand, that is, of consumption both by the various economic sectors and final consumption by families and individuals.

Rural:

Rural consumption grew by 7.3% in 2011, with the connection of 121,057 rural properties to electricity supply for the first time, and increased demand for electricity for irrigation due to atypical climatic conditions: low rainfall in the rainy season, and higher than expected temperatures in the dry season.

Other consumer categories:

The total of other types of consumption in 2011 — by public authorities, public illumination, public services, and Cemig’s own consumption — was 9.2% higher than in 2010.

Revenue from wholesale electricity sales

The volume of electricity sold to other concession holders was 1.78% higher, at 14,457,890 MWh in 2011, than in 2010 (14,204,530 MWh), and average price in these sales was 7.24% higher, at R$ 109.08/MWh in 2011, compared to R$ 101.72/MWh in 2010. As a result, revenue from wholesale supply to other concession holders was 9.13% higher year-on-year, at R$ 1,577 in 2011, than in 2010 (R$ 1,445).

Revenue from use of the electricity distribution systems (TUSD)

The revenue of Cemig D and Light from the Tariff for Use of the Distribution Systems (TUSD) was 19.30% higher, at R$ 1.978bn, in 2011, than in 2010 (R$ 1.658bn). This revenue comes from charges made to Free Consumers on energy sold by other agents of the electricity sector, and its increase arises both from the increases in tariffs and, principally, from a higher volume of transport of energy for free consumers, a consequence of the recovery of industrial activity and of migration of captive clients to the Free Market.

Revenue from use of the transmission grid

Revenue for use of the grid in 2011 was R$ 1.407 billion, vs. R$ 1.197 billion in 2010, an increase of 17.54%.

For the older concessions, the Revenue for use of the transmission grid refers to the tariff charged to agents in the electricity sector, including Free Consumers connected to the high voltage network, for use of that part of the National transmission Grid that is owned by the Company, less the amounts received that are used for amortization of the financial asset.

For the new concessions, it includes the portion received from agents of the electricity sector relating to operation and maintenance of the transmission lines and also the adjustment to present value of the transmission financial asset constituted, primarily, during the period of construction of the transmission facilities. The rates used for updating of the asset correspond to the remuneration on capital applied to the undertakings, and these vary in accordance with the model of undertaking and the investing company’s cost of capital.

68

Table of Contents

The increase in this revenue in 2011 arises principally from monetary updating of the Transmission Asset of Taesa, with an impact of R$ 178 million on Cemig’s profit. The updating arises from publication of the index for updating of Taesa’s tariff as from July 2011, by 9.77%.

The sector charges that result in deductions from operational revenue in 2011 totaled R$ 6,997bn, compared to R$ 6,095bn in 2010, an increase of 14.8%. The main variations in these deductions from revenue between the two years are as follows:

The Fuel Consumption Account — CCC

Expenses on the CCC in 2011 were R$ 718mn, 34.96% more than their total of R$ 532mn in 2010. This charge is for the costs of operation of the thermal plants in the national grid and in the isolated systems. It is prorated between electricity concession holders, on a basis set by a Resolution issued by the regulator, Aneel.

This is a non-controllable cost: in the distribution activity, the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment. For the portion relating to transmission services, the Company charges the CCC amount to Free Consumers on their invoices and passes it on to Eletrobrás. The variation in this cost arises, principally, from the change in the method of calculation of the charge, which makes good the difference between the total cost of generation of electricity in the isolated systems and the average cost of electricity sold in the Regulated Market.

CDE — Energy Development Account

Expenses on the CDE in 2011 were R$ 516mn, 21.99% more than their total of R$ 423mn in 2010. These payments are specified by a Resolution issued by the regulator, Aneel.

This is a non-controllable cost: in the distribution activity, the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment. For the portion relating to transmission services the Company merely charges the CDE amount to Free Consumers on their invoices for use of the grid, and passes it on to Eletrobrás.

Table of Contents

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.

For a breakdown of the charged applied to revenues, please see Explanatory Note 24 to the consolidated financial statements for 2011.

Operational costs and expenses (excluding Financial revenue/expenses)

Operational costs and expenses (excluding Financial revenue (expenses)) totaled R$ 11.445bn in 2011, 12.21% more than in 2010 (R$ 10.200bn). See the principal expenses and costs in Explanatory Note 25 to the consolidated financial statements for 2011.

The following paragraphs outline the main variations in expenses:

Electricity bought for resale

The expense on electricity bought for resale in 2011 was R$ 4.278 billion, 14.94% higher than the figure of R$ 3.722 billion for 2010. The increase primarily reflects greater sales activity by Cemig GT (Generation and Transmission), and the increase in the equity interest in Light in 2011, with greater consolidation of its operations. This is a non-controllable cost: in the distribution activity, the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment. For more information please see Explanatory Note 25 to the consolidated financial statements for 2011.

Charges for use of the transmission grid

The expense on charges for use of the transmission network in 2011 was R$ 830mn, vs. R$ 729mn in 2010, an increase of 13.85%.

This expense refers to the charges, set by an Aneel Resolution, payable by electricity distribution and generation agents for use of the facilities that are components of the national grid. This is a non-controllable cost: the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment.

Depreciation and amortization

Depreciation and amortization was 9.71% higher year-on-year: R$ 983mn in 2011, compared to R$ 896mn in 2010. This mainly reflects the increase in the assets of the concession due to the Company’s increased investment program, primarily in distribution.

Employee post-retirement liabilities

The expense on post-employment obligations in 2011 was R$ 124mn, compared to R$ 107 million in 2010, an increase of 15.89%. This expense represents the updating of the obligation, calculated in accordance with an actuarial opinion prepared by external consultants. The significant increase arises from the increased equity interest in the subsidiary Light.

Operational provisions

Operational provisions in 2011 totaled R$ 257mn, 86.23% more than in 2010 (R$ 138mn). The main elements in the higher figure are:

70

Table of Contents

The provision for doubtful receivables was 55.24% higher, at R$ 163 million in 2011, vs. R$ 105 million in 2010.

The provision for Aneel administrative proceedings was R$ 4 million in 2011, whereas there was reversal of provisions of R$ 47 million in 2010 resulting from dismissal of a case brought by Aneel about the low-income subsidy.

A provision of R$ 48 million for contingencies for legal actions in general was made in 2011, compared to a reversal of R$ 54 million in provisions in 2010.

On the other hand, provisions for civil actions relating to tariff increases totaled R$ 9 million in 2011, compared to R$ 139 million provisioned in 2010. The amounts provisioned in 2010 were substantially from settlement to terminate a legal action brought by an industrial consumer relating to the tariff increase ordered by Ministerial Order 045/86 of the National Water and Electricity Authority (DNAEE) in 1986.

For more details please see Explanatory Note 25 to the consolidated financial statements for 2011.

Gas purchased for resale

Expenses on gas bought for resale in 2011 were R$ 329mn, 46.22% more than their total of R$ 225mn in 2010. This primarily reflects the increase in the volume purchased, reflecting higher sales of gas by Gasmig in 2011, in turn reflecting increased industrial activity.

Outsourced services

The expense on outsourced services in 2011 was R$ 1.031bn, compared to R$ 923 million in 2010, an increase of 11.70%. The highest increases were in communication services, meter reading services, electricity bill delivery and consultancy, all mainly reflecting increases in prices in service contracts. A breakdown of outsourced services is given in Explanatory Note 25 to the consolidated financial statements for 2011.

Employees’ and managers’ profit shares

The expense on employees’ and managers’ profit shares in 2011 was R$ 221 million, 32.00% less than in 2010 (R$ 325 million). The amounts reported arise from the Specific Employment Agreements signed with the unions in November of 2010 and 2011. The amount reported for 2010 also contains an element of R$ 30 million arising under the Collective Employment Agreement for the previous year, 2009.

Table of Contents

The main non-recurring items affecting 2011 Ebitda are:

Recognition of an expense of R$ 178mn in Cemig D, in 2010, arising from the settlement of a legal action brought by an industrial consumer, for reimbursement of the tariff increase introduced by the DNAEE during the Cruzado economic plan (of 1986).

Recognition of an ICMS tax expense in 2010 relating to the subsidy for the discount on tariffs for low-income consumers, in the amount of R$ 26mn, resulting from the decision to subscribe to the Tax Amnesty program put in place by the government of Minas Gerais State.

Net financial revenue (expenses)

The company posted net financial expenses of R$ 970 million in 2011, compared to net financial expenses of R$ 825 million in 2010. The main factors in this financial result are:

Higher expense on costs of loans and financings: Higher expenses on loans and financings: R$ 1.311 billion in 2011, compared to R$ 1.075 billion in 2010, due mainly to the higher variation in the CDI (Interbank CD) rate, the main indexor for loan and financing contracts, reflecting the increase of the Selic rate, mainly during the first half of 2011.

Higher monetary updating expense on post-retirement liabilities: R$ 163 million in 2011, compared to R$ 142 million in 2010 — mainly due to higher variation in the IPCA index, which is used to update the debt agreement between Cemig and the private pension entity, Forluz.

Revenue from monetary updating of escrow payments into court in legal proceedings: R$ 68 million in 2011, from updating of a tax credit for successful final judgment in a legal action on the ITCD (Death Duties and Donations) tax.

Revenue from monetary updating applied to the Finsocial tax: R$ 68 million in 2011, from an updated receivable from the Brazilian federal tax authority for taxes paid unduly over the period 1989—91, following final judgment in favor of Cemig.

Expense on monetary updating of an advance against future capital increase (AFAC): R$ 66 million in 2011 for updating of a historic amount of R$ 27 million repaid to the Finance Department of Minas Gerais State.

For a breakdown of financial revenues and expenses, please see Explanatory Note 26 to the 2011 financial statements.

Income tax and Social Contribution tax

In 2011, Cemig’s expenses on income tax and the Social Contribution totaled R$ 918 million, on profit of R$ 3.333 million before tax, a percentage of 27.53%. In 2010, Cemig’s expenses on income tax and the Social Contribution totaled R$ 564 million, on profit of R$ 2.822 billion before tax, a percentage of 19.99%. These effective rates are reconciled with the nominal rates in Explanatory Note 10 to the consolidated financial statements for 2011.

Table of Contents

It should be noted that in 2011 and 2010 the Company posted tax credits that are not explicitly stated in the financial statements, in the amounts of R$ 120 million and R$ 289 million, respectively.

Net profit of 2010 and 2009 compared

Cemig reported net profit of R$ 2.258 billion in 2010, 5.81% more than its 2009 net profit of R$ 2.134 billion.

Operational revenue

This is the breakdown of operational revenues:

R$ million |  | 2010 (Reclassified) |  | 2009 (Reclassified) |  | Change, % |
Overall revenue from supply of electricity |  | 14,821 |  | 14,743 |  | 0.53 |
Revenue from Use of the Distribution Systems (TUSD) |  | 1,658 |  | 1,332 |  | 24.47 |
Revenue from use of the transmission grid |  | 1,198 |  | 903 |  | 32.56 |
Construction revenue |  | 1,341 |  | 1,291 |  | 3.95 |
Other operational revenues |  | 924 |  | 917 |  | 0.76 |
Deductions from operational revenues |  | (6,095 | ) | (5,737 | ) | 6.24 |
Net operational revenue |  | 13,847 |  | 13,449 |  | 2.96 |

Revenue from supply of electricity

Revenue from total supply of electricity in 2010 was R$ 14.821 billion, compared to R$ 14.743 billion in 2009 — an increase of 0.53%.

Final consumers

Revenue from sales of electricity to final consumers (excluding Cemig’s own consumption) was R$ 13.219 bn in 2010, 1.94% more than in 2009 (R$ 12.968 bn).

The main factors in this result are:

Volume of energy invoiced to final consumers (excluding Cemig’s own consumption) 6.06% higher.

Average tariff 3.35% lower in 2010, at R$ 282.01 vs. R$ 291.79 in 2009. This is due to the higher volume of regulatory items included in the tariff in 2009 — for example the Extraordinary Tariff Recomposition (RTE), and non-controllable costs (CVA) of the distribution company.

Revenue from wholesale electricity sales

The volume of electricity sold to other concession holders was 2.49% higher, at 14,204,520 MWh in 2010, than in 2010 (13,859,700 MWh), and average price in these sales was R$ 101.72/MWh in 2011, compared to R$ 117.87/MWh in 2009. This reduction mainly reflected electricity contracts made through Adjustment Auctions for sale to distributors that were signed exclusively in 2009, with average price of R$ 145/MWh. As a result, revenue from wholesale supply to other concession holders was 11.57% lower year-on-year, at R$ 1.445bn in 2010, compared to R$ 1.634bn in 2009.

Revenue from use of the electricity distribution systems (TUSD)

The revenue of Cemig D and Light from the Tariff for Use of the Distribution Systems (TUSD) was 24.47% higher, at R$ 1.658bn, in 2010, than in 2009 (R$ 1.332bn). This revenue comes from charges made to Free Consumers on energy sold by other agents of the electricity sector, and its increase arises from a higher volume of transport of energy for free consumers, a consequence of the recovery of industrial activity and of migration of captive clients to the free market.

Revenue from use of the transmission grid

Revenue for use of the grid was 32.67%, or R$ 295 million, higher in 2010, at R$ 1.198bn (compared to R$ 903 million in 2009).

This revenue is from the transmission capacity of Cemig GT made available to the national grid, and also from the jointly-controlled transmission subsidiaries, among which we highlight the transmission groups known as TBE and Taesa.

The increase in this revenue in 2010 is mainly due to acquisition of interests in Taesa, in October 2009, and in May 2010 through a public offer to acquire shares, which increased these revenues in 2010.

Other operational revenues

The Company’s other operational revenues are:

|  | Consolidated — IFRS |
|  | 2010 (Reclassified) |  | 2009 (Reclassified) |
Supply of gas |  | 398 |  | 307 |
Charged service |  | 16 |  | 17 |

Sector charges — deductions from operational revenue

The sector charges that result in deductions from operational revenue in 2010 totaled R$ 6,095bn, compared to R$ 5,737bn in 2009, an increase of 6.24%. The main variations in these deductions from revenue between the two years are as follows:

The Fuel Consumption Account — CCC

Expenses on the CCC in 2010 were R$ 532mn, 7.91% more than their total of R$ 493mn in 2009. This charge is for the costs of operation of the thermal plants in the national grid and in the isolated systems. It is prorated between electricity concession holders, on a basis set by a Resolution issued by the regulator, Aneel.

This is a non-controllable cost: in the distribution activity, the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment. For the portion relating to transmission services the Company charges the CCC amount to Free Consumers on their invoices and passes it on to Eletrobrás.

Table of Contents

CDE — Energy Development Account

Expenses on the CDE in 2010 were R$ 423mn, 3.68% more than their total of R$ 408mn in 2009. These payments are specified by a Resolution issued by the regulator, Aneel. This is a non-controllable cost: in the distribution activity, the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment. For the portion relating to transmission services the Company merely charges the CDE amount to Free Consumers on their invoices for use of the grid, and passes it on to Eletrobrás.

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.

For a breakdown of these charges that result in deductions from revenues, please see Explanatory Note 23 to the consolidated financial statements for 2010.

Operational costs and expenses (excluding Financial revenue/expenses)

Operational costs and expenses (excluding Financial revenue (expenses)) totaled R$ 10.200bn in 2010, 4.53% more than in 2009 (R$ 9.758bn). This is mainly due to increases in the non-controllable costs of Electricity bought for resale. For more information please see Explanatory Note 24 to the consolidated financial statements for 2010.

The following paragraphs outline the main variations in expenses:

Electricity bought for resale

The total expense on Electricity bought for resale in 2010 was R$ 3.722bn, 16.35% more than in 2009 (R$ 3.199bn), mainly reflecting greater purchases by the distributors in the Regulated Market. This is a non-controllable cost: the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment. There is a breakdown of this expense in Explanatory Note 24 to the consolidated financial statements for 2010.

The following paragraphs outline the main variations in expenses:

Charges for use of the transmission grid

The expense on charges for use of the transmission network in 2010 was R$ 729mn, vs. R$ 853mn in 2009, a reduction of 14.54%.

This expense refers to the charges, set by an Aneel Resolution, payable by electricity distribution and generation agents for use of the facilities that are components of the national grid. This is a non-controllable cost: the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment.

Personnel

Total personnel expenses in 2010 were R$ 1.211bn, 8.12% less than in 2009 (R$ 1.318bn). This result largely reflects a much higher expense on the PDV Voluntary Retirement Program in 2009

75

Table of Contents

(when it was put in place), with an expense in that year of R$ 206mn, compared to only R$ 40mn in 2010 (an adjustment of the provision made in 2009). This is associated with reduction of the aggregate number of employees (of the holding company, of Cemig D and of Cemig GT) from 9,746 at the end of 2009 to 8,859 at the end of 2010.

Depreciation and amortization

The expense on depreciation and amortization was unchanged from 2009 to 2010, at R$ 896mn.

Employee post-retirement liabilities

The expense on post-employment obligations in 2010 was R$ 107mn, compared to R$ 150 million in 2009, a reduction of 28.67%. These expenses basically represent the interest applicable to Cemig’s actuarial obligations, net of the investment yield expected from the assets of the pension plans, estimated by an external actuary. The reduction of this expense was due to the higher expectation of returns on the assets of the Plan in 2010 in comparison with the obligations.

Financial revenue (expenses)

The principal impacts on the Company are those described below:

The company posted net financial expenses of R$ 825 million in 2010, compared to net financial expenses of R$ 354 million in 2009. The main factors in this financial result are:

Higher expense on costs of loans and financings: R$ 1.075 million in 2010, compared to R$ 799 million in 2009. The higher figure reflects entry of new financings, one of the most important being the issue of R$ 2.7bn in Promissory Notes by Cemig GT in October 2009, settled in March 2010 with the proceeds of a debenture issue in March 2010, of the same amount.

Increase in the expense of monetary variation on Loans and financings in Brazilian currency: R$ 144 million in 2010, compared to R$ 9 million in 2009. This reflects, substantially, the higher volume of funding raised, and also the change in inflation indices and other indexors of contracts on the company’s loans, financings and debentures — principally the IGP—M inflation index, which was 1.72% negative over the whole of 2009, and 11.32% positive over the whole of 2010.

Income tax and Social Contribution

Cemig’s expenses on income tax and the Social Contribution tax in 2010 totaled R$ 564 million, on profit of R$ 2,822 billion before tax, a percentage of 19.99%. This compares with 2009, when Cemig’s expenses on income tax and the Social Contribution totaled R$ 1.131 billion, on profit of R$ 3,337 billion before tax, a percentage of 33.89%.

The lower percentage rate of taxes in 2010 is due to tax losses that were recognized in 2010, in the amount of R$ 289mn. These credits are for tax losses that were not recorded in the financial statements and were recognized in 2010 as a result of proof of their realization through the projections of the Company’s results.

Table of Contents

Liquidity and capital resources

Our business is capital-intensive. Historically, we have a need for capital to finance the construction of new generation facilities and expansion and modernization of the existing generation, transmission and distribution facilities.

Our demands for liquidity are also related to our dividend policy. We finance our liquidity and capital needs principally with cash generated by operations and, on a lesser scale, with funds from financing. We believe that our present cash reserves, generated by operations and expected funds from financings, will be sufficient to meet our liquidity needs over the next 12 months.

Cash and cash equivalents

Cash and cash equivalents at December 31, 2012 totaled R$ 2.486 billion, which compares with R$ 2.862 billion on December 31, 2011. On December 31, 2012 neither our cash position nor our cash equivalents were maintained in any other currencies than the Real. The reasons for the reduction are given below.

Cash flow from operational activities

Cemig’s totals of Net cash generated by operational activities in 2012 and 2011 were, respectively, R$ 2.734 billion and R$ 3.898 billion. The lower total of cash generated by operations in 2012 than 2011 mainly reflects higher outflow of cash in payment of bought electricity.

Cash flows from investment activities

Net cash used in investment activities in 2012 and 2011 was, respectively, R$ 1.720 billion and R$ 4.017 billion. The lower amount consumed in investment activities in 2012 than 2011 is mainly due to the net cash received from the early settlement of the CRC account, of R$ 1.901 billion, and the dilution of a jointly-controlled subsidiary, in the amount of R$ 645mn.

Cash used in financing activities

Cash flow consumed by financing activities in 2012 totaled R$ 1.391 billion, with amortization of financings totaling R$ 6.838 billion, and payments of R$ 1.748 billion in dividends and Interest on Equity; with R$ 7.195 billion received from financings.

Cash flow generated by financing activities in 2011 totaled R$ 1 billion, with amortization of financings totaling R$ 2.218 billion, and payments of R$ 2.036 billion in dividends and Interest on Equity; with R$ 4.255 billion received from financings.

Impact of inflation, of the variation in prices of principal inputs and products, of the exchange rate and of interest rates, on the Issuer’s operational result and financial result

In the distribution activity, the principal effects on profit come from tariff adjustments, as follows:

Increase in consumer tariffs for Cemig D, with average impact for captive consumers of 7.24%, from April 8, 2011 (full effect in 2012).

Tariff increase for Light, with average effect on consumer tariffs of 7.82%, from November 7, 2011 (full effect in 2012).

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

77

Table of Contents

The majority of the contracts of free consumers for purchase of generated electricity are indexed to the IGP-M inflation index.

Contracts for sale of electricity in the regulated market are mainly updated by the IPCA inflation index, published by the IBGE.

In the transmission activity, contracts are mostly updated by the variation in the IGP-M inflation index.

The result of the Company’s Financial revenue (expenses) line is mainly influenced by the CDI rate: 47% of the Company’s debt contracts are linked to these indexors.

10.3 Events, past or expected, with material effects on the financial statements

a . Introduction or disposal of an operational segment

No such event occurred in the business years of 2012, 2011 or 2010.

b. Constitution, acquisition or disposal of an equity interest

New acquisitions

Additional acquisition of equity interest in Gasmig

On December 27, 2011 the Board of Directors authorized the acquisition of nominal preferred shares representing 4.38% of the total capital of Gasmig belonging to the government of the State of Minas Gerais, for R$ 67,223, corresponding to a price per share of approximately R$ 3.75, to be adjusted by the amount indicated in an independent valuation opinion, to be prepared by a specialized institution, to be chosen and contracted by Cemig.

Acquisition by Taesa of the remaining 50% of Unisa

On November 30, 2011, Taesa acquired from Abengoa, for R$ 799,738,000, 50% of the share capital of Unisa (formerly Abengoa Participações S.A.), the corporate objects of which are to hold interests in the equity capital of companies that provide public and private electricity transmission services. Unisa, on that date, held 100% of the shares in the transmission companies STE, ATE, ATE II and ATE III.

On March 16, 2012, Taesa signed a contract with Abengoa for acquisition of the remaining 50% of the share capital of Unisa. Conclusion of the transaction and actual transfer of the shares was at that time subject to certain conditions precedent. On July 3, 2012 Taesa concluded acquisition of the remaining 50% of the shares in Unisa held by Abengoa. This transaction was approved by Cade, the Brazilian monopolies authority, on July 4, 2012.

Based on the above, from November 30, 2011 to July 3, 2012, Unisa was jointly-controlled by Taesa and Abengoa, and as from July 4, 2012 (the acquisition date), became a wholly-owned subsidiary of Taesa. The total value of the consideration paid for the acquisition of the holding was R$ 876,193, comprising R$ 902,390 paid in cash, net of constitution of dividends receivable in the amount of R$ 27,717 and accounts payable in the amount of R$ 1,520, on the date of calculation of the transaction, under the terms of the agreement signed by the parties.

Light: Additional acquisition of shares in April 2011

On April 12, 2011 the jointly-controlled subsidiary Parati acquired 54.08% of the total share capital of Redentor, for a total amount of R$ 403,350, corresponding to a price per share of R$ 6.87. Redentor owns 13.03% of the total and voting stock of Light.

Since the transaction resulted in the transfer of control of Redentor, Parati made a public offering to acquire the remaining shares in Redentor.

On September 30, 2011 this auction was settled with the payment of R$ 7.20 per share, in the amount of R$ 333,775, representing 93.04% of the shares in circulation that were held by the minority stockholders. This acquisition represented 42.72% of the total share capital, and was made for the price of R$ 7.20, the same price per share paid to the controlling stockholder on May 12, 2011, updated by the variation in the Selic rate from that date to September 30, 2011.

Light: Additional acquisition of shares in July 2011

On July 7, 2011 Parati acquired 100% of the holdings in Luce, owner of 75% of the units of FIP Luce, which in turn is the indirect holder, through Luce Empreendimentos e Participações S.A., of approximately 9.77% of the total and voting stock of Light.

The amount paid for the acquisition was R$ 515,946. As a result of this transaction and as specified in the Unit Holders’ Agreement of FIP Luce, Braslight, holder of the remaining 25% of the units of FIP Luce, acquired an option to sell its interest to Parati, which, if exercised, should take place in a maximum period of 60 days.

On July 15, 2011, Parati was notified, through Luce, by Braslight, that Braslight had exercised the option to sell its holding of 25% in FIP Luce, and this was executed on July 28, 2011. The amount paid to Braslight for this acquisition was R$ 171,982.

With these acquisitions, Parati now held 25.68% of the voting stock of Light. Cemig owns 25% of Parati and Redentor Fundo de Investimento em Participações owns 75%.

Acquisition of stockholding in Abengoa

On June 2, 2011, the jointly-controlled subsidiary Taesa signed share purchase agreements with the Abengoa Group, the first being for 100% of a concession, and the second for a 50% holding in a company formed with Abengoa, owning four electricity transmission assets. Taesa acquired: (i) 50% of the shares held by Abengoa Concessões Brasil Holding S.A. in the share capital of Abengoa Participações Holding S.A., which in turn holds 100% (one hundred per cent) of the total shares of the following transmission companies:

STE — Sul Transmissora de Energia S.A., |  | ATE Transmissora de Energia S.A.,
ATE II Transmissora de Energia S.A., and |  | ATE III Transmissora de Energia S.A.;

and

(ii) 100% of the shares held by Abengoa Concessões Brasil Holding S.A. and by Abengoa Construção Brasil Ltda.in the share capital of: NTE - Nordeste Transmissora de Energia S.A. This transaction increased Taesa’s Brazilian transmission market share (share of the total Permitted Annual Revenue — Receita Annual Permitida, or RAP) from 6.5% to 8.6%. For this acquisition the Company paid, with the proceeds of its fourth issue of promissory notes, for the two Share Purchase

Agreements, the total amount of R$ 1.17 billion, on November 29, 2011, at the completion of the transaction.

Acquisition of interests in EATE and ETEP

In 2011, the Company acquired, from Eletrobrás, preferred shares in EATE and ETEP corresponding to 11.45%, and 8.02%, respectively, of the share capital of those companies. The amounts paid for these additional equity interests were R$ 91.060mn and R$ 13.145mn, respectively, totaling R$ 104.205mn. The discount on the acquisition of the interests in these companies, in the amount of R$ 99.771mn, corresponds to the difference between the amount paid and the book value of the interest in the Stockholders’ equity of EATE and ETEP, and arises from the increase in value of the concessions. Such premiums will be amortized over the remaining period of the concessions.

Acquisition of additional holding in Taesa

On May 6, 2010 Cemig GT, through Transmissora Alterosa de Energia Elétrica, made a Public Offering for Acquisition of Shares and Units held by minority stockholders. In the transaction, 24.42% of the shares were acquired from minority stockholders, for R$ 1.002 billion, equivalent to R$ 15.57 per share. The premium on the transaction was R$ 523 million.

With this transaction, Cemig GT and the investment fund Fundo de Investimentos em Participação Coliseu completed the process of acquisition of Taesa (formerly Terna Participações). Some of the minority stockholders did not accept the Public Offer to Buy shares: 4.72% of the shares in Taesa remain in circulation in the market.

In the case of Companhia Energética de Minas Gerais — Cemig these practices differ from IFRS, applicable to the separated financial statements, only in relation to the valuation of the investments in subsidiaries and jointly-controlled subsidiaries by the equity method, whereas for the purposes of IFRS this would be cost or fair value.

hydroelectric power plant which, in accordance with the financial projections prepared by its Management, are to be absorbed by the revenues from the operations. The realization of the consolidated fixed asset constituted by the said expenditure, which on December 31, 2010 totaled R$ 7.0779 billion, will, in accordance with management’s expectations, take place as from the start of the operations, planned for December 2011. The proportional amount relating to the Company is R$ 707.8 million, in fixed assets.”

10.5 Critical accounting policies

The preparation of the individual and consolidated financial statements, under IFRS and the rules of the CPC, requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the amounts reported in assets, liabilities, revenues and expenses. Future reported results may differ from these estimates.

Estimates and assumptions are reviewed continuously, using as a reference historic experience and also any significant alterations in scenario that might affect the equity situation and/or the profits of the Company in the applicable items. Revisions in relation to accounting estimates are recognized in the period in which the estimates are reviewed, and in any future periods affected.

The principal estimates related to the financial statements refer to recording of the effects arising from:

Allowance for doubtful accounts — see Note 8.

Deferred income tax and Social Contribution tax — see Note 10.

Financial Assets of the Concession — Note 13.

Intangible assets — Note 16.

10.6 Internal controls relating to the preparation of the financial statements — Degree of efficiency and deficiency, and recommendations made in the Auditor’s Report

Degree of efficiency of such controls, indicating any imperfections and measures taken to correct them

The Executive Board, including the CEO and the Chief Officer for Finance and Investor Relations, is responsible for establishing and maintaining a system of internal controls adopted to ensure the preparation of reliable financial statements.

The internal controls to ensure the preparation of reliable financial statements include procedures that were implemented to prove, with reasonable certainty: (i) reliability of the records of accounting and financial information; (ii) the preparation of accounting statements in accordance with accounting practices adopted in Brazil; (iii) processing of payments and receipts in accordance with authorizations of the management; and (iv) timely detection of inappropriate acquisitions, and of disposal or allocation of material assets. We emphasize that, due to the limitations inherent to the internal controls, there is the possibility that such controls may not prevent nor detect all deficiencies.

81

Table of Contents

Also, forecasts in relation to assessment of the effectiveness of the internal controls are subject to the risk that the controls might cease to function due to changes in the conditions in which they operate or cease to be in accordance with established policies and procedures.

Management has assessed the effectiveness of the internal controls adopted to ensure preparation of reliable financial statements at December 31, 2012, based on the criteria established in the document Integrated Internal Control Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, and concluded that, on December 31, 2012, the system of internal controls adopted to ensure the preparation of reliable financial statements is effective.

Deficiencies and recommendations on the internal controls present in the external auditor’s report

No material deficiencies in internal controls were reported such as might adversely affect the reliability of the financial statements.

REPORT OF THE EXTERNAL AUDITORS ON THE FINANCIAL STATEMENTS

To the Stockholders, Members of the Board of Directors, and Managers

Companhia Energética de Minas Gerais — CEMIG

Belo Horizonte, Minas Gerais

We have examined the individual and consolidated financial statements of Companhia Energética de Minas Gerais — CEMIG (“the Company”), respectively identified as the Holding Company Financial Statements and the Consolidated Financial Statements, which comprise the Statement of Financial Position (balance sheet) on December 31, 2012 and the related Profit and Loss Account, Statement of Comprehensive Income, Statement of Changes in Stockholders’ Equity and Statements of Cash Flows for the business year ended on that date, and the summary of the principal accounting practices and other explanatory notes.

Management’s responsibility for the financial statements

The Company’s Management is responsible for the preparation and appropriate presentation of the individual financial statements in accordance with accounting practices adopted in Brazil, and of the consolidated Financial statements in accordance with International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB), and also in accordance with accounting practices adopted in Brazil; and also for the internal controls that it has decided are necessary to make possible the preparation of those financial statements free of material distortion, whether caused by fraud or error.

Responsibility of the external auditors

Our responsibility is to express an opinion on those financial statements based on our audit, conducted in accordance with Brazilian and international auditing rules. These rules require compliance by the auditors with ethical requirements, and that the audit should be planned and executed with the objective of obtaining a reasonable degree of certainty that the financial statements are free of material distortion.

An audit involves execution of selected procedures to obtain evidence on amounts and disclosures presented in the financial statements. The procedures selected depend on the auditor’s judgment, including evaluation of the risks of material distortion in the financial statements, whether caused by fraud or error. In this evaluation of risks, the auditor considers the internal controls that are material for the preparation and appropriate presentation of the Company’s financial statements, for the purpose of planning the auditing procedures that are appropriate in the circumstances, but not for the purposes of expressing an opinion on the efficacy of those internal controls of the Company. An audit also includes evaluation of the appropriateness of the accounting practices used and of the

85

Table of Contents

reasonableness of the accounting estimates made by the management, and also evaluation of the presentation of the financial statements taken as a whole.

We believe that the auditing evidence obtained is sufficient and appropriate as grounds for our qualified opinion.

Basis for qualified opinion

As described in Explanatory Note 16 to the financial statements, as part of the process of tariff review of the electricity distributors, on March 11, 2013 the Financial and Economic Inspection Department (Superintendência de Fiscalização Econômico Financeira, or SFF) of Aneel issued Dispatch No. 689, stating the value of the Regulatory Remuneration Base (Base de Remuneração Regulatória, or BRR) of the subsidiary Cemig Distribuição S.A., to be R$ 5,111,837,000. The BRR is used to determine the amount of the financial asset value of electricity distribution concessions, relating to the amount to be reimbursed by the concession-granting power at the termination of the concessions. As stated in the Explanatory Note referred to, it is the understanding of the Company’s management that the amount published by the SFF is provisional and was publicly disclosed at an amount substantially lower than its expectations, and for this reason the Company’s management is in discussion with Aneel about the valuation criteria used for determination of the BRR that is to be homologated. Faced with this situation, it is the understanding of the Company’s management that, at the present moment, no adjustment can be decided to the accounting balances recorded on December 31, 2012. Consequently, no adjustment has been recorded arising from this subject in the financial statements and, for as long as the discussions with Aneel are not concluded, it is not possible to reach a conclusion on the possible impacts on the balances of Financial assets, the Net profit for the year or the Stockholders’ equity of the Company on December 31, 2012.

Opinion on the individual financial statements

In our opinion, except for the possible effects of the subject described in the paragraph “Basis for qualified opinion”, the individual financial statements of Companhia Energética de Minas Gerais — CEMIG referred to above adequately present, in all material aspects, the equity and financial position of Companhia Energética de Minas Gerais — CEMIG on December 31, 2012, the performance of its operations, and its cash flows, for the business year ended on that date, in accordance with the accounting practices adopted in Brazil.

Opinion on the Consolidated Financial Statements

In our opinion, except for the possible effects of the subject described in the paragraph “Basis for qualified opinion”, the consolidated financial statements of Companhia Energética de Minas Gerais — CEMIG referred to above adequately present, in all material aspects, the consolidated equity and financial position of Companhia Energética de Minas Gerais — CEMIG on December 31, 2012, the consolidated performance of its operations, and its consolidated cash flows, for the business year ended on that date, in accordance with International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB) and with the accounting practices adopted in Brazil.

Emphases

a. As described in Explanatory Notes 2.6(i) and 13, the property, plant and equipment assets of the activity of electricity generation in the regime of independent power producer are depreciated over their estimated useful life, and the financial assets related to the activities of distribution of natural gas are realized through indemnity from the respective concession-granting power, the facts and circumstances that are mentioned in the said notes being taken into account. As and when new information or decisions from the regulatory bodies or from the concession-granting

86

Table of Contents

powers become known, the present period of depreciation of the property, plant and equipment assets, or the manner in which the financial assets are realized, may, or may not, be changed. We make no qualification to our Opinion as a result of this matter.

b. As explained in Explanatory Note 1(a), the jointly-controlled subsidiary Madeira Energia S.A. and its subsidiary are incurring expenses on development of the project for construction of the Santo Antônio Hydroelectric Plant. On December 31, 2012 the balance of property, plant and equipment assets of this jointly-controlled subsidiary, included in the Company’s consolidated financial statements, is in the amount of R$ 1,452,735,000. During this development phase of the project, the jointly-controlled subsidiary Madeira Energia S.A. has reported recurrent losses in its operation and recorded a balance of current liabilities that is larger than its current assets. As described in Explanatory Note 1(a), the Management of Madeira Energia S.A. has plans to cure the situation of negative net working capital, and, on today’s date, Madeira Energia S.A. depends upon the financial support of its stockholders and/or upon obtaining of loans from third parties to continue operating.. We make no qualification to our Opinion as a result of this matter.

c. As described in Explanatory Note 2.1, the individual financial statements were prepared in accordance with accounting practices adopted in Brazil. In the case of Companhia Energética de Minas Gerais — CEMIG, these practices differ from IFRS, which is applicable to the separate financial statements, only in relation to the valuation of the investments in subsidiaries, affiliates and jointly-controlled subsidiaries made by the equity method, while for the purposes of IFRS they would be valued at cost or fair value. We make no qualification to our Opinion as a result of this matter.

Other matters

Statements of added value

We have also examined the individual and consolidated Added Value Statements (DVAs), for the business year ended December 31, 2012, prepared under the responsibility of the Company’s Management, the presentation of which is required by the Brazilian Corporate Law legislation for listed companies, and which is supplementary information under IFRS, which do not require presentation of the DVA. These statements have been submitted to the same auditing procedures described above and, in our opinion, except for the possible effects of the subject described in the paragraph “Basis for qualified opinion”, are adequately presented, in all material aspects, in relation to the financial statements taken as a whole.

Auditing of the individual and consolidated financial statements for the year ended December 31, 2011 and of the individual and consolidated statements of financial position on January 1, 2011.

The information and the amounts corresponding to the year ended December 31, 2011 and to the statements of financial position raised on January 1, 2011, which are presented for the purposes of comparison, now re-presented for the reasons described in Explanatory Note 2.5, were audited by other independent auditors, who issued a report, dated March 27, 2013, which contained a paragraph of emphasis related to the subject described in item “b” above.

The principal objective of the Company’s remuneration policy is to establish a system of remuneration of management that helps align the interests of management with those of the stockholders.

As determined in the Bylaws, the global or individual amount of the remuneration of the Executive Board, the Board of Directors and Committees, and the Audit Board is decided by the General Meeting of Stockholders.

The Ordinary and Extraordinary General Meetings of Stockholders held, concurrently, on April 27, 2012, decided the Annual Global Financial Allocations for Remuneration of Management and Members of the Audit Board, comprising the Board of Directors, the Executive Board and the Audit Board, in the amount of up to R$ 16,400,000.00 (sixteen million four hundred thousand Reais), including health insurance for the Chief Officers, to be contracted at the same level as for the Company’s employees, with the monthly remuneration of the Chief Executive Officer being set at R$ 35,000,00 (thirty five thousand Reais), and the remuneration of the other Chief Officers, individually, at R$ 30,000.00 (thirty thousand Reais), the amounts receivable by the Chief Officers for paid leave, bonuses and other benefits being adjusted proportionately.

b. Composition of the remuneration, indicating:

i. Description of the elements of the remuneration and the objectives of each one of them

a) The Board of Directors

The members of the Company’s Board of Directors receive remuneration divided into a fixed part, comprising a salary or pro-labore payment and direct benefits, and a variable part, comprising an amount equivalent to their attendance at meetings and for profit-sharing.

In the Ordinary and Extraordinary General Meetings of Stockholders held concurrently on April 27, 2012, a fixed monthly remuneration was set, for each member of the Board of Directors, except those sitting or substitute members who are also Chief Officers, and subject to the condition relating to the payment of the jeton mentioned below, equivalent to 20% of the monthly remuneration that a Chief Officer of the Company receives, that is to say R$ 6,091.91 (six thousand ninety one Reais and ninety one centavos). The substitute members are remunerated only when they are substituting sitting members.

Of this amount, 50% is equivalent to the salary or pro-labore, which is paid only to the sitting members of the Company’s Board of Directors. The other 50% is equivalent to the remuneration for participation in meetings, and is represented by jetons paid to the sitting member or to the substitute member who substitutes the sitting member in meetings. In the event of there being more than one meeting in the month, the jeton will be divided proportionately over the number of meetings held, and received by the sitting Member or by the substitute Member who replaces that Member; in the event of there not being a meeting in the month, the sitting Member shall receive the total amount of the monthly remuneration; in the event of there being a meeting in the month and neither the sitting Member nor his or her substitute Member attending, the portion relating to the jeton shall not be payable, and the sitting Member shall receive the amount equivalent to his or her pro-labore.

The other components of the remuneration of the Board of Directors are the Company’s contribution to the National Social Security System (INSS) on the salary and the meeting

attendance payment. To members of the Board of Directors that are resident in other municipalities than that of the head office of the Company, the Company offers the direct benefit of reimbursement of the expenses of travel and accommodation necessary for them to attend the meetings and carry out their functions, equivalent to approximately 10% of the total monthly remuneration of a Board Member, per meeting at which they attend. Further, the Company provides members of the Board of Directors with optional inscription in a Group Life Insurance Policy, paid for entirely by the Company, and also optional participation in a retirement plan, paid for 50%/50% by the Board Member and the Company.

The fixed remuneration (12 monthly remunerations) and other components of the remuneration (the Company’s INSS contribution) aim to compensate the members of the Board of Directors for the time dedicated to the performance of their functions and for their contributions to the Company, established based on assessment of their duties and responsibilities, and also, in counterpart, making it possible for the Chairman of the Board of Directors to demand effort and performance by each one of its members.

The remuneration proportional to attendance aims to motivate attendance by members at the meetings that are called, contributing to effective participation in the conduct of business and effective performance of their functions.

b) The Executive Board

The members of Cemig’s Executive Board receive a fixed remuneration, comprising a salary or pro-labore and direct benefits, and a variable remuneration, represented by a share in the profits of the Company.

Under the by-laws, the global or individual amount of the remuneration of the Executive Board, including benefits of any type, must be fixed by the General Meeting of Stockholders, in accordance with the legislation currently in effect. The Chief Officers also have the right to an annual leave, of not more than 30 (thirty) days, non-cumulative, during which they have the right to a remuneration equivalent to their monthly remuneration plus one-third.

The company grants the following direct benefits to its Chief Officers:

(i) monthly, on the 25th day of each month on the first prior business day, an amount equivalent to the meal vouchers established for the employees in the Collective Employment Agreement, for the subsequent months, provided electronically, on the basis of the sharing factor in accordance with salary levels;

(ii) optional membership of a group life insurance policy paid for totally by the Company; and

(iii) an optional health and dental insurance plan, paid for entirely by the Company (in the case of special dependents, the amount is paid for totally by the Chief Officer).

Further, the Company grants to Chief Officers optional participation in a post-employment private pension plan, paid for 50%/50% by the Chief Officer and the Company.

Other components of the remuneration of the Chief Officers are an annual bonus in the amount of the monthly salary, payments for paid leave, the Company’s contribution to the INSS, and payment of the FGTS amount on the salary and profit sharing amounts received.

The variable remuneration for the Executive Board consists of profit sharing, paid two times per year: one according to the same criteria established in the Specific Collective Employment Agreement of the Company, and the other paid in the form of an advance against the Company’s profit, with a calculation, in the following year, of comparison with the targets established by the Board of Directors.

The fixed remuneration or pro-labore of the Executive Board aims to compensate the time dedicated to the performance of their functions and their extraordinary contributions to the

133

Table of Contents

Company, being established based on assessment of the value of their duties and responsibilities and the value of their services in the market.

The purpose of the concession of these direct benefits is to make the remuneration package more attractive, complementing the fees and the legal benefits of the Chief Officers, functioning also as a motivational strategy tool in relation to the Managers, since the mandatory charges on payroll that are such a burden for hiring do not apply to the amount paid.

The aim of this variable remuneration is to motivate the members of the Executive Board toward effective participation in the conduct of the business, through a reward linked to the organization’s performance.

The Company grants its Chief Officers, as an act only of generosity, monthly payment of contribution to the FGTS.

c) Audit Board

The members of the Audit Board receive only a fixed remuneration, comprising salary or pro-labore and direct benefits.

The Ordinary and Extraordinary General Meetings of Stockholders held concurrently on April 27, 2012 set the remuneration of each Sitting Member of the Audit Board at 10% (ten per cent) of the average remuneration of a Chief Officer of the Company, i.e. R$ 3,045.45 (three thousand forty five Reais and forty five centavos); and also specified the monthly remuneration of each Substitute Member of the Audit Board to be equivalent to 80% (eighty per cent) of the monthly remuneration of the Sitting Member, i.e. R$ 2,436.36 (two thousand four hundred and thirty six Reais and thirty six centavos), in both cases excluding the benefits normally applicable under the Law.

The company also offers, as direct benefits to members of the Audit Board, sitting or substitute, who are resident in other municipalities than that of the head office of the Company, reimbursement of expenses of travel and accommodation between the municipality of their residents and that of the Company necessary for their attendance at the meetings or carrying out their functions, equivalent to approximately 10% (ten per cent) of the total monthly remuneration of the Member, for each meeting they attend. The Company gives its Chief Officers optional membership of a Group Life Insurance Policy paid for totally by the Company.

The other components of the remuneration of the members of the Audit Board comprise the Company’s contribution to the INSS on the salary received. The aim of salary or pro-labore for the members of the Audit Board is to compensate the time dedicated to the performance of their functions and to their contributions to the Company, established based on assessment of their duties and responsibilities, also making it possible for performance to be requested, in counterpart, from each one of its members.

The aim of the direct benefits is to pay for expenses of travel and food of the members of the Audit Board who are resident in other municipalities than that of the Company’s head office, and also to provide the options for inscription in a Group Life Insurance Policy.

d) Board of Directors’ Support Committee

All the substitute members of the Board of Directors who are on the Board of Directors Support Committee, other than the Board Members who exercise the position of Chief Officers, receive additional and specific remuneration due to the fact that they take part in the Committee, equivalent to the remuneration established for the Sitting Board Member. However, the substitute members of the Board of Directors that have received specific remuneration for taking

134

Table of Contents

part in meetings of the Board of Directors Support Committee do not receive additional jetons for replacing effective sitting members in meetings of the Company’s Board of Directors.

The remuneration is divided into a fixed component and a variable component in proportion to attendance, the pre-determined component (salary or pro-labore) being equivalent to 50% of the stipulated monthly remuneration of sitting Members of the Board of Directors. The variable component proportional to attendance (remuneration for participation in meetings) is represented by the other 50% of the monthly remuneration stipulated, divided into jetons paid. In the event of there being more than one meeting in the month, the jeton will be divided proportionately over the number of meetings held; in the event of there not being a meeting in the month, the total amount of the monthly remuneration is paid. In the event of there being a meeting in the month and the Member of the Board of Directors Support Committee not attending, the portion relating to the jeton shall not be payable, and the Member shall receive only the fixed portion.

As direct benefits, the Company offers the members of the Board of Directors Support Committee resident in other municipalities than that of the head office of the Company, reimbursement of the expenses of air travel and accommodation necessary for them to attend the meetings and carry out their functions, equivalent to approximately 10% of the total monthly remuneration of a Board Member, per meeting at which they attend. The Company also gives members of the Board of Directors Support Committee optional membership of a Group Life Insurance Policy, paid for totally by the Company.

The other components of the remuneration of the Support Committee are the Company’s contribution to the National Social Security System (INSS) on the salary, and payment for participation in meetings, received.

The aim of salary or pro-labore for the members of the Board of Directors Support Committee is to compensate the time dedicated to the performance of their functions and to their contributions to the Company, established based on assessment of their duties and responsibilities, also making it possible for performance to be requested, in counterpart, from each one of its members.

The remuneration proportional to attendance aims to motivate the members of the Committee to attend the meetings that are called, so as to guarantee effective participation in the conduct of business and effective performance of their functions of support to the Board of Directors.

The direct benefits aim to pay for expenses of travel and meals of the members of the Board of Directors Support Committee that are resident in other municipalities than that of the Company’s head office.

e) Other Committees of the Board of Directors

No additional direct or indirect remuneration or benefit is paid to the sitting or substitute members of the Board of Directors for participation in the other committees of the Board of Directors.

Others |  | 15.51 | %

iii. Methodology of calculation and adjustment of each one of the elements of the remuneration

The amounts of remuneration paid by the Company to its Managers are established in General Meeting of Stockholders.

There is no methodology of adjustment established for the remuneration paid by the Company to its managers.

iv. Reasons for the composition of the remuneration

The composition of the remuneration is justified solely and exclusively on the basis of the proposal by the majority stockholder, the State of Minas Gerais, approved by the Ordinary and Extraordinary General Meetings of Stockholders held on April 27, 2012.

Those meetings also decided to allocate the Annual Global Amount to be distributed for composition of the portions of remuneration of the Board of Directors, the Board of Directors Support Committee, the Executive Board and the Audit Board.

v. Principal indicators of performance that are taken into consideration in the determination of each element of the remuneration

The remuneration of the Managers that is linked to performance indicators is the profit sharing (“PLR” — Participação em Lucros e Resultados), a component of the variable remuneration.

In the year of 2011, since the results of the indicators calculated at the end of the third quarter exceeded 50% of the previously agreed annual targets, relating to the PLR for 2011, Cemig made early distribution, on December 28, 2011, of 70% of the stipulated amount.

136

Table of Contents

The amount paid earlier was compensated in the final amount calculated in 2012 in accordance with the variable annual targets according to strategy of the Company. These corporate targets were established by the Board of Directors. The payment of the PLR in the first half of 2012 was made in the month subsequent to the filing of the annual Financial Statements with the CVM (Securities Commission). In the second half of 2012, Cemig brought forward and paid, on November 29, 2012, 70% of the stipulated amount, that would be offset in the final amount to be calculated in 2013 in accordance with the annual targets.

c. How the remuneration is structured to reflect changes in the performance indicators

In the determination of the fixed remuneration of the Company’s managers, the behavior of performance indicators is not applied.

The variable remuneration (PLR) of the managers is linked to the Company’s indicators of profits and results. As from 2012, the PLR paid to the Chief Officers is conditional upon the individual corporate targets as established by the Board of Directors in accordance with the Company’s strategy being met.

d. How the remuneration policy or practice aligns with the short-, medium- and long-term interests of the Issuer

The Company’s remuneration policy incorporates elements of alignment to the interests of the Company, in the short, medium and long term. The short-term results — considering these to be the annual results — are aligned with the Company’s remuneration policy in relation to payment of the variable remuneration referred to as “Profit Sharing” (PLR). In this case, the Company’s results during the year will define the amount to be attributed to each manager member of the Executive Board.

The alignment in the medium and long term is the result of the element: consistency, in compliance with the targets relative to the principal indicators, on an annual basis.

f. Existence of remuneration paid by subsidiaries or controlling stockholders, whether direct or indirect

Since management of the companies of the group is shared between Cemig, Cemig Geração e Transmissão S.A. and Cemig Distribuição S.A., the amounts that relate to each one of these companies are recognized, proportionally, in the related accounting statements. Thus, in the Standard Financial Statements, the amounts proportional to each company are stated. In the period of nine months ended September 30, 2012, and in the business years closing on December 31, 2011, 2010 and 2009, the wholly-owned subsidiaries Cemig Geração e Transmissão S.A. and Cemig Distribuição S.A. bore amounts proportional to the allocation of the Executive Boards and of the Board of Directors in the respective companies, as shown below

|  | 30/09/2012 |  | 31/12/2011 |  | 31/12/2010 |  | 31/12/2009 |

Total |  | 7,884 |  | 11,937 |  | 7,811 |  | 6,735 |

g. Existence of any remuneration or benefit linked to the occurrence of any corporate event, such as disposal of stockholding control of the Issuer

There is a provision for payment of indemnity corresponding to 40% of the balance on the FGTS account in the event of dismissal. In view of its indemnity character, only those Chief Officers who are exonerated from their position before the end of the period of office are entitled to this penalty payment, and this view cannot be applied if the removal from office takes place at the request of the Chief Officer himself.

Cemig makes the deposits of FGTS for its Chief Officers and, considering the legal understanding contained in Opinion JR-1809/2002 of December 13, 2002, to the effect that the penalty payment on deposits made during the period of office of the Chief Officer should be applied to those who were employees of the Company, the right was extended to those Chief Officers who were not employees, to comply with the constitutional principle of equality of status and rights.
