February 25, 2015 Companhia Energetica de Minas Gerais (CIG-NYSE) NEUTRAL Current Recommendation Prior Recommendation Outperform Date of Last Change 06/15/2014 Current Price (02/24/15) $4.41 Target Price $4.75 SUMMARY CEMIG s long-term prospects appear bright as electricity demand in Brazil is expected to increase in the years ahead. To leverage benefits from the rising demand, the company is keen to increase its production and distribution capacity. Also, acquisitions play an important role in boosting the company s growth prospects. Also, the company s agreement for participation in the construction of 25 wind farms is expected to work in its favor. Moreover, the payment of dividends and interest on equity will boost shareholders return. However, rising operating expenses, governmental interference and dependence on hydro sources for electricity might prove to be potential headwinds for the company, going forward. Thus, we maintain a Neutral recommendation on CEMIG.

OVERVIEW Companhia Energetica de Minas Gerais (CIG), known as CEMIG, is one of the largest integrated electric utilities in Brazil. Approximately 97% of the company s installed generation capacity is hydroelectric power. Currently, the company is the fifth-largest electricity generator in Brazil. Currently, the company meets roughly two-thirds of its power needs from the internal generation assets and purchases, and the rest from third parties. CEMIG s customer base, which includes residential, industrial, commercial and rural customers, is located primarily in the south-eastern state of Minas Gerais. In addition to its integrated electricity business, CEMIG is engaged in natural gas distribution and telecommunications. The state government of Minas Gerais is the company s largest shareholder with 51% stake in voting shares. The company is the third-largest transmission company in Brazil with a 13% market share and more than 10,000 km of transmission lines across the nation. The company operates through a number of subsidiaries, of which two prime ones are Cemig Dis tribuicao (Cemig Distribution or Cemig D) and Cemig Geracao e Transmissao (Cemig Generation and Transmission or Cemig GT). REASONS TO BUY CEMIG operates in one of the promising industries of Brazil. The country s electricity market is the largest in South America with an installed capacity of 129 thousand Megawatts (MW) as on Jun 2014, including 3,428 MW generated by wind firms. The installed wind capacity is anticipated to reach 22,439 MW in 2023, according to the Ministry of Mines and Energy's (MME) 10-year energy expansion plan. Energy consumption in Brazil is expected to rise in the years ahead. Globally, demand for electricity is anticipated to grow 56% during 2010 2040, according to the International Energy Outlook 2013 published by the U.S. Energy Information Administration (EIA) in Jul 2013. CEMIG is making earnest efforts to improve its electricity generation capacity and distribution services. In first-half 2014, the company acquired 49.9% stake in Retiro Baixo Energética. The latter operates the Retiro Baixo hydroelectric plant, which has an installed generation capacity of 83.7 MW. Also, the company acquired 12.4% interest in Madeira Energia. In third-quarter 2014, CEMIG and Renova Energia agreed to participate in construction of 25 wind farms, with an installed generation capacity of 676.2 MW. In Oct 2014, the company increased its stake in Renova to 27.37% while also acquiring 40% equity interest in Gasmig. The stake increase in Gasmig is part of a strategy for the creation of a new company, Gás Natural do Brasil S.A. Over a period of 30 years, the company targets to capture a major share of the Brazilian generation and distribution businesses, thus becoming the chief player in the Brazilian electricity utility sector. CEMIG s integrated nature of operations (generating and distributing energy), along with its aggressive expansion plans, ensures its presence among industrial customers all over the south and southeast Brazil. For Cemig D, the company anticipates earnings before interest, tax, depreciation and amortization (EBITDA) to be within R$1,719 R$2,023 million in 2015. For Cemig GT, EBITDA is projected to be within R$2.2 R$4.1 billion in 2015. Consolidated EBITDA is predicted within R$5.9 R$8.1 billion in 2015. For 2014 2018, planned investments are anticipated to be roughly R$4.4 billion for Cemig D and R$2.6 billion for Cemig GT. Equity Research CIG Page 2

REASONS TO SELL RECENT NEWS CEMIG s disappointing performance in third-quarter 2014 was largely a result of escalating operating expenses, especially costs related to electricity brought for resale, and losses arising from equity contribution from subsidiaries. Electricity sold to final consumers edged down 0.7% year over year. In the quarters ahead, any unchecked increases in expenses can prove detrimental to the company s profitability. With nearly 51% of its stake lying with the government of the Brazilian state of Minas Gerais, CEMIG s business operations are influenced by political intervention. This may impact the company s performance unfavorably, as interests of the state government might not agree with those of the minority shareholders. Also, the company faces a natural limitation on its generation capacity, as hydroelectric power plants cannot generate more electricity than what is made possible by the available water resources. Lack of sufficient water resources due to dry weather conditions may compel the company to use thermoelectric generation plants, which entails significantly high costs. Brazilian electric utility companies face other problems that must be considered. Based on higher productivity and lower cost of capital, ANEEL (Agência Nacional de Energia Elétrica) decides the tariff revision for companies to regulate a monopolistic environment. The more efficient the companies, the greater the tariff cut on a periodic basis. Naturally, as this legislation creates a difficult business environment, each company must operate efficiently in the short term in order to take advantage of the tariff over the long term. Subsequently, any efficiency gains will be incorporated into prices and thus the company, paradoxically, will find itself penalized for greater efficiency. Interest on Equity On Dec 26, 2014, CEMIG announced payment of interest on equity amounting to R$230 million or R$0.18 per share for 2014. The payment will be made in two instalments, with the first one on Jun 30, 2015 and the second on Dec 30, 2015. Third-Quarter 2014 Highlights On Nov 13, 2014, CEMIG reported third-quarter results. Adjusted net income came in at R$26.6 million (US$11.7 million), down 96.1% year over year. Revenues: CEMIG generated net revenue of R$3,831.9 million (US$1,688.1 million), reflecting a yearover-year increase of 8.1%. Sales to end consumers accounted for 98% of the net revenue generated. Electricity sold to CEMIG s final consumers edged down 0.7% year over year to 15,466 Megawatt hours (MWh). Expenses/Income: Operating expenses escalated 22% year over year to R$3,420 million (US$1,506.6 million). The increase was due to higher costs related to electricity brought for resale, use of the national grid, post-retirement liabilities, personnel and managers, employees and managers profit shares, materials, depreciation and amortization, operational provisions and other expenses. On the other hand, partially offsetting these were decreased costs associated with royalties for use of water resources. Equity Research CIG Page 3

Adjusted EBITDA fell 56.7% year over year to R$490.4 million (US$216 million) while EBITDA margin was 12.8% versus 31.9% in the year-ago quarter. Balance Sheet and Cash Flow: Exiting third-quarter 2014, CEMIG had cash and cash equivalents of R$1,327 million (US$546.1 million) as against R$1,989 million (US$904.1 million) recorded at the previous quarter-end. Loans and financings inched up 0.2% sequentially to R$2,089 million (US$859.7 million). In the first nine months of 2014, CEMIG generated cash of R$3,249 million (US$1,412.6 million) from its operating activities, reflecting an increase of 22% year over year. Capital spent on fixed and intangible assets plummeted 75% to R$614 million (US$267 million). Stake increase in Renova On Oct 28, 2014, CEMIG announced that it presently holds 27.37% equity interest in Renova. This happened after Renova issued roughly 8.7 million shares for R$17.7789 per share. Stake increase in Gasmig On Oct 14, 2014, CEMIG announced to have successfully completed acquiring 40% equity interest in Gasmig held by a subsidiary of Petrobras, Gaspetro. The transaction value was approximately R$570.9 million. The acquisition is part of a strategy for the creation of a new company, Gás Natural do Brasil S.A. On Jun 16, CEMIG and Gas Natural Fenosa entered into an agreement for the creation of Gás Natural do Brasil S.A. The new company will deal with natural gas projects. Equity Research CIG Page 4
