NU REPORTS FIRST QUARTER RESULTS

HARTFORD, Connecticut, May 5, 2010—Northeast Utilities (NYSE: NU) today reported first quarter 2010 earnings of $86.2 million, or $0.49 per share, compared with earnings of $97.7 million, or $0.60 per share, in the first quarter of 2009.  

Charles W. Shivery, NU chairman, president, and chief executive officer, attributed the lower results primarily to lower electric and natural gas sales, reduced earnings at NU’s competitive businesses due to the absence of mark-to-market gains, and higher employee benefit costs, due in part to the enactment of national health care legislation.  NU recorded $3 million in after-tax charges in the first quarter of 2010 associated with the health care legislation.  In addition, earnings per share were impacted by the sale of nearly 19 million NU shares in March 2009.  

Distribution segment earnings of NU’s four utilities totaled $47.9 million in the first quarter of 2010, compared with $59.2 million in the first quarter of 2009.  “Our electric operating companies provide critical infrastructure for nearly 2 million customers, and we continue to invest heavily to maintain reliable systems, but economic conditions continue to weigh on the returns of their distribution businesses,” Shivery said.  

In the first three months of 2010, NU’s capital expenditures totaled $182.7 million, including $84 million on its electric and natural gas distribution systems.  

2010 earnings guidance

NU today affirmed its 2010 consolidated earnings guidance of between $1.80 per share and $2.00 per share.  NU continues to project earnings from its regulated electric and natural gas distribution and electric generation segment of between $0.95 per share and $1.05 per share ¹ and between $0.90 per share and $0.95 per share¹ for its transmission segment.  It projects earnings of between $0.00 and $0.05 per share ¹ at its competitive businesses and net expenses of approximately $0.05 per share ¹ at NU parent and other companies.

Regulated company results

NU’s transmission earnings were $40.1 million, or $0.23 per share ¹, in the first quarter of 2010, compared with $35.4 million, or $0.22 per share ¹, in the first quarter of 2009.  Shivery said the improved results primarily reflected a higher level of transmission investment.  

The Connecticut Light and Power Company’s (CL&P) distribution earnings were $14.3 million in the first quarter of 2010, compared with $21.6 million in the first quarter of 2009.  The lower results were due to a 4.9 percent decline in retail sales owing to much warmer weather and a continued economic slowdown in Connecticut, as well as higher pension and other operating costs.

Public Service Company of New Hampshire’s (PSNH) distribution and generation earnings were $11.1 million in the first quarter of 2010, compared with $13.5 million in the first quarter of 2009.  PSNH benefited from a temporary rate increase that took effect August 1, 2009, but that revenue was more than offset by a 5.3 percent decline in retail sales and $1 million of charges related to the new health care legislation.

Western Massachusetts Electric Company’s (WMECO) distribution earnings were $2.9 million in the first quarter of 2010, compared with $4.8 million in the first quarter of 2009.  Lower results in 2010 were primarily due to a 4.4 percent decline in retail sales in the first quarter of 2010, compared with the first quarter of 2009.

Overall, NU’s retail electric sales were down 4.9 percent in the first quarter of 2010 compared with the first quarter of 2009.  They were down 2.5 percent on a weather-adjusted basis.

Shivery said the first-quarter sales decline reflects a number of factors, including a much milder New England winter in 2010.  “Our electric sales results also reflect the very significant ongoing investment in energy conservation measures our customers continue to make, the region’s slow recovery from the economic downturn, and our Connecticut customers’ installation of distributed generation,” Shivery said.

Yankee Gas Services Company earned $19.6 million in the first quarter of 2010, compared with $19.3 million in the first quarter of 2009.  Lower interest expense was partially offset by a 3.5 percent decline in firm natural gas sales, driven by a 13.5 percent reduction in year-over-year heating degree days in Connecticut.  Firm natural gas sales rose 6.4 percent on a weather-adjusted basis.

Competitive businesses

NU’s remaining competitive energy businesses earned $2.3 million in the first quarter of 2010, compared with $5.8 million in the first quarter of 2009.  The decline was primarily due to reduced benefits from marking to market the remaining wholesale obligations of NU Enterprises, Inc. (NUEI).  NUEI recorded after-tax mark-to-market losses of $0.4 million in the first quarter of 2010, compared with after-tax gains of $3.2 million in the first quarter of 2009.  NU’s wholesale marketing business continues to wind down, with the last contracts ending in 2013.

Parent and other affiliates

NU parent and other companies recorded net expenses of $4.1 million in the first quarter of 2010, compared with net expenses of $2.7 million in the first quarter of 2009.  First quarter 2010 results included a charge of $0.6 million related to the new health care legislation.

¹ All per share amounts in this news release are reported on a fully diluted basis.  The only common equity securities that are publicly traded are common shares of NU parent.  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 NU'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 fully diluted NU parent common shares outstanding for the period.  Management uses this non-GAAP financial measure to evaluate earnings results and to provide details of earnings results and guidance by business.  Management believes that this measurement is useful to investors to evaluate the actual and projected financial performance and contribution of NU’s businesses.  Non-GAAP financial measures should not be considered as alternatives to NU consolidated net income attributable to controlling interests or EPS determined in accordance with GAAP as indicators of NU’s operating performance.
