Eversource Energy Reports First Quarter 2018 Results

(HARTFORD, Conn. and BOSTON, Mass. – May 2, 2018) Eversource Energy (NYSE: ES) today reported first quarter 2018 earnings of $269.5 million, or $0.85 per share, compared with earnings of $259.5 million, or $0.82 per share, in the first quarter of 2017.

Also today, the Eversource Energy Board of Trustees declared a regular quarterly dividend of $0.505 per share, payable June 29, 2018 to shareholders of record as of May 24, 2018. Additionally, the company today reaffirmed its 2018 earnings per share (EPS) guidance of $3.20 to $3.30 and its projected 5 to 7 percent long-term EPS growth rate.

“We had a very solid start to 2018, despite extremely challenging weather conditions in March, resulting from an unprecedented three major Nor’easters in 11 days,” said James J. Judge, Eversource Energy chairman, president and chief executive officer. “We thank our customers who showed great support, patience and appreciation for our employees’ efforts on their behalf following the storms, and we are so grateful to thousands of Eversource employees for their tireless work during that difficult period.”

Electric Transmission

Eversource Energy’s transmission segment earned $107.4 million in the first quarter of 2018, compared with earnings of $94.2 million in the first quarter of 2017. Higher transmission earnings were primarily due to Eversource Energy’s additional investment in its electric transmission system.

Electric Distribution

Eversource Energy’s electric distribution and generation segment earned $104.2 million in the first quarter of 2018, compared with earnings of $114.1 million in the first quarter of 2017. Lower results were due primarily to the sale of generation assets, as well as higher depreciation, property tax, operations and maintenance expense, partially offset by higher electric distribution margins. Higher operations and maintenance expense was driven primarily by higher storm-related costs in 2018.

Natural Gas Distribution

Eversource Energy’s natural gas distribution segment earned $57.8 million in the first quarter of 2018, compared with earnings of $50.8 million in the first quarter of 2017. Stronger sales were partially offset by higher operations and maintenance expense.

Water Distribution

Eversource Energy’s water distribution segment, which was created when Eversource acquired Aquarion Water Company in December 2017, earned $1.5 million in the first quarter of 2018. Water distribution earnings are heavily weighted in the warmer months of the year, the opposite of natural gas distribution earnings.

Parent and other companies

Parent and other companies had a net loss of $1.4 million in the first quarter of 2018, compared with earnings of $0.4 million in the first quarter of 2017, due primarily to higher interest expense.

The following table reconciles consolidated earnings per share for the first quarters of 2018 and 2017:

¹All 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 common shares outstanding for the period. Management uses this non-GAAP financial measure to evaluate earnings results, provide details of earnings results by business, and more fully compare and explain our first quarter 2018 and 2017 results. 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.
