Eversource Energy Reports Full Year 2015 Results

(HARTFORD, Conn. and BOSTON, Mass. – February 4, 2016)  Eversource Energy (NYSE: ES) today reported full-year 2015 earnings of $878.5 million, or $2.76 per share, compared with full-year 2014 earnings of $819.5 million, or $2.58 per share.  Full-year results included after-tax integration costs of $15.8 million in 2015 and $22.1 million in 2014.  Excluding those integration costs, Eversource Energy earned $894.3 million, or $2.81 per share¹, in 2015 and $841.6 million, or $2.65 per share¹, in 2014.

In the fourth quarter of 2015, Eversource Energy earned $181.8 million, or $0.57 per share, compared with earnings of $221.6 million, or $0.69 per share, in the fourth quarter of 2014.  Excluding integration costs, Eversource Energy earned $189.8 million, or $0.60 per share¹, in the fourth quarter of 2015, compared with earnings of $230.3 million, or $0.72 per share¹, in the fourth quarter of 2014.

“2015 was a very successful year for Eversource Energy,” according to Thomas J. May, the company’s chairman, president and chief executive officer.  “We invested the most dollars ever in New England’s energy delivery systems, achieved our best ever level of electric service reliability, connected record numbers of new natural gas heating customers, posted very strong financial results, and made significant progress in addressing the region’s energy infrastructure challenges.”

2016 and Long-Term Earnings Guidance

Also today, Eversource Energy projected 2016 earnings per share (EPS) of between $2.90 per share and $3.05 per share and long-term EPS growth through 2019 of between 5 percent and 7 percent, using recurring 2015 earnings of $2.81 per share as the base value.  Eversource reduced its long-term EPS growth rate from the previous 6 percent to 8 percent primarily due to the impact of the extension of bonus income tax depreciation through 2019.

Electric Distribution and Generation

Eversource Energy’s electric distribution and generation segment earned $507.9 million for the full year of 2015, excluding integration costs of $0.6 million, compared with earnings of $462.4 million for the full year of 2014.  Full year results benefited from higher revenues and lower operation and maintenance costs, partially offset by higher depreciation and property tax expense.  In the fourth quarter of 2015, the electric distribution and generation segment earned $88.1 million, compared with earnings of $113.3 million in the fourth quarter of 2014.  Lower fourth quarter results were due primarily to a higher effective tax rate, higher depreciation and property tax expense, and the impact of much warmer than normal weather on unit sales.

Electric Transmission

Eversource Energy’s transmission segment earned $304.5 million for the full year of 2015, compared with earnings of $295.4 million for the full year of 2014.  The transmission segment earned $79.5 million in the fourth quarter of 2015, compared with earnings of $88.6 million in the fourth quarter of 2014.  Higher full-year earnings were due to an increased level of investment in Eversource Energy transmission facilities and a lower level of net charges related to reviews by the Federal Energy Regulatory Commission (FERC) of the authorized return on equity (ROE) for the owners of New England’s electric transmission system.  The fourth quarter of 2014 benefited from a reserve adjustment related to the FERC ROE review.

Natural Gas Distribution

Eversource Energy’s natural gas distribution segment earned $72.4 million for the full year of 2015, excluding integration costs of $0.2 million, compared with earnings of $72.3 million for the full year of 2014.  Fourth quarter natural gas segment earnings were $14.9 million in 2015, compared with $28.1 million in 2014.  Lower fourth quarter results were driven primarily by record warm temperatures in December 2015, which caused a 16.2 percent decline in fourth quarter natural gas sales, compared with the fourth quarter of 2014.

Eversource Energy parent and other companies

Excluding integration costs, Eversource Energy parent and other companies earned $9.5 million for the full year of 2015, compared with earnings of $11.5 million for the full year of 2014.  In the fourth quarter of 2015, excluding integration costs, Eversource parent and other companies earned $7.3 million, compared with earnings of $0.3 million in the fourth quarter of 2014.

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 Energy parent common shares outstanding for the period.  In addition, fourth quarter and year-end 2015 and 2014 earnings and EPS excluding certain integration costs 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 fourth quarter and full-year results without including the impact of the 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 Energy consolidated net income attributable to controlling interests or EPS determined in accordance with GAAP as indicators of Eversource Energy’s operating performance.
