Eversource Energy Reports First Quarter 2015 Results

HARTFORD, Conn. and BOSTON, Mass. (April 29, 2015) – Eversource Energy (NYSE: ES) today reported first quarter 2015 earnings of $253.3 million, or $0.80 per share, compared with first quarter 2014 earnings of $236 million, or $0.74 per share.  Excluding integration costs of $4 million in 2015 and $5.8 million in 2014, Eversource earned $257.3 million, or $0.81 per share¹, in the first quarter of 2015, compared with $241.8 million, or $0.76 per share¹, in the first quarter of 2014.

“We are pleased with both our operational and financial performance in the first quarter of 2015,” said Thomas J. May, Eversource chairman, president and chief executive officer.  “Our electric and natural gas delivery systems performed extremely well throughout the bitter weather New England experienced this past winter.  Additionally, our financial results are consistent with our previously announced recurring 2015 earnings guidance of between $2.75 and $2.90 per share.”

Also today, the legal name change of Northeast Utilities to Eversource Energy was approved at the company’s 2015 Annual Meeting of Shareholders and the Eversource Energy Board of Trustees declared a regular quarterly dividend of $0.4175 per share, payable June 30, 2015 to shareholders of record as of May 29, 2015.

Electric Distribution and Generation

Eversource Energy’s electric distribution and generation segment earned $130.6 million in the first quarter of 2015, compared with earnings of $112.2 million in the first quarter of 2014.  Improved results primarily reflect higher distribution revenues in the first quarter of 2015, compared with the same period of 2014, and the impact of regulatory orders on NSTAR Electric Company that were fully anticipated by the company.  One order approved a settlement involving refunds to customers related to reliability and  expense energy efficiency cost recovery mechanisms.  The other order was related to the recovery of bad debt expense associated with NSTAR Electric’s basic service energy supply to customers.  The favorable impacts of the regulatory orders were partially offset by higher operation, depreciation, amortization and property tax expense.

Electric Transmission

Eversource Energy’s transmission segment earned $66.6 million in the first quarter of 2015, compared with earnings of $74.9 million in the first quarter of 2014.  Lower transmission earnings were directly related to the impact of an order issued in March 2015 by the Federal Energy Regulatory Commission that affects the returns on equity earned by all electric transmission owners in New England.  That decision resulted in a $12.4 million after-tax charge, primarily at The Connecticut Light and Power Company and Western 

Massachusetts Electric Company, and was partially offset by an increase in Eversource’s continued investment in its electric transmission system.

The first-quarter earnings of Eversource Energy’s electric utility subsidiaries are noted below in millions, net of preferred dividends:

Natural Gas Distribution

Eversource Energy’s natural gas distribution segment earned $55.6 million in the first quarter of 2015, compared with earnings of $52.1 million in the first quarter of 2014.  Improved results primarily reflect colder weather in 2015, which increased firm natural gas sales.  Eversource’s firm natural gas sales were 8.4 percent higher in the first quarter of 2015 than the first quarter of 2014.  Both quarters were much colder than average.  

Parent and Other Companies

Parent and other companies earned $4.5 million in the first quarter of 2015, excluding $4 million of integration expenses, compared with earnings of $2.6 million in the first quarter of 2014, excluding $5.8 million of integration expenses.  The results primarily reflect lower operation and income tax expense.  The following table reconciles consolidated earnings per share for the first quarters of 2015 and 2014.

Financial results for the first quarters of 2015 and 2014 for Eversource Energy’s business segments and parent and other companies are noted below:

¹ All per share amounts in this news release are reported on a diluted basis.  The only common equity securities that are publicly traded are common shares of Eversource Energy.  The earnings and EPS of each business do not represent a direct legal interest in the assets and liabilities allocated to such business, but rather represent a direct interest in Eversource Energy's assets and liabilities as a whole.  EPS by business is a non-GAAP (not determined using generally accepted accounting principles) measure that is calculated by dividing the net income or loss attributable to controlling interests of each business by the weighted average diluted Eversource parent common shares outstanding for the period.  In addition, first quarter 2015 and 2014 earnings and EPS excluding certain integration costs related to the April 10, 2012 closing of the merger between Northeast Utilities and NSTAR are non-GAAP financial measures.  Management uses these non-GAAP financial measures to evaluate earnings results and to provide details of earnings results by business and to more fully compare and explain our first quarter 2015 and 2014 results without including the impact of the non-recurring integration costs.  Management believes that this measurement is useful to investors to evaluate the actual and projected financial performance and contribution of Eversource Energy’s businesses.  Non-GAAP financial measures should not be considered as

alternatives to Eversource consolidated net income attributable to controlling interests or EPS determined in accordance with GAAP as indicators of Eversource Energy’s operating performance.
