Exhibit 99.1 KEYSPAN NEWS - -------------------------------------------------------------------------------- KeySpan Corporation For Immediate Release Contacts: Investors Media Relations George Laskaris 718.403.2526 718.403.2503 KeySpan Announces Strong 2nd Quarter Results -------------------------------------------- KeySpan/National Grid Transaction Receives New Hampshire Approval Settlement Reached in New York Pro-Rata Dividend Approved Brooklyn, New York, August 3, 2007 - KeySpan Corporation (NYSE: KSE) announced consolidated earnings of $52.2 million or $0.30 per share for the second quarter of 2007, as compared to $49.4 million or $0.28 per share for the same period last year. For the six month period ended June 30, 2007, KeySpan reported consolidated earnings of $265.6 million or $1.51 per share, compared to $257.4 million or $1.47 per share for the same period last year. These favorable results for both the quarter and year-to-date reflect higher operating income, primarily driven by the strong performance of the gas distribution segment and lower expenses associated with the National Grid transaction, partially offset by lower earnings in the electric segment. In addition, 2007 results reflect higher financing and tax expenses compared to 2006, which benefited from the settlement of certain New York City and IRS issues in the second quarter of 2006. "I am pleased with the impressive results and the excellent performance of our core gas distribution business, which benefited from strong customer demand. We continued to demonstrate the organic growth of our gas distribution system with the addition of approximately 18,500 gas installations on a year-to-date basis. We are on track to achieving our goal of $50 million in additional gross profit margin in the gas business," said Robert B. Catell, KeySpan Chairman and Chief Executive Officer. "Although our electric business reported lower results primarily due to increased competition in the New York City market, our generation plants are well maintained and ready to meet the increasing demand in both the New York City and Long Island markets. Our financial condition remains strong with a 49.4% debt to total capitalization ratio". The previously announced acquisition of KeySpan by National Grid continues to move forward as the required federal and state regulatory approvals are progressing. All federal and shareholder approvals have been received. With respect to state approvals, on July 16, 2007 the New Hampshire Public Utilities Commission approved National Grid's acquisition of KeySpan and the merger of the two companies. New York State is the final regulatory approval necessary to close the transaction. On July 9, 2007, National Grid filed a "joint proposal" reflecting an agreement with Staff of the New York Public Service Commission and other parties on the acquisition of KeySpan. Based on the latest procedural schedule, the New York Commission is expected to act on the joint proposal on August 22nd. "I am pleased with the recent approval received in New Hampshire and the settlement reached in New York. With these two significant events, we are now in the final stages of completing the merger and bringing significant benefits to our customers in New York," said Mr. Catell. "We expect the transaction to close shortly after the New York State Commission approval is received. The National Grid-KeySpan merger will provide more than $600 million in savings to our gas customers in New York City and Long Island over the next five years, on top of additional savings that will be realized by the Long Island Power Authority and National Grid's upstate New York gas and electric customers. These savings will provide base rate stability to our customers through 2012. We look forward to completing the transaction this month and becoming an important part of one of the largest and most efficient energy companies in the world." Segment Highlights Results in 2007 and 2006 are reported on an Operating Income basis as follows: - ------------------------------------------------------------------------------------------------------------------- 2nd 2nd YTD YTD Operating Income / (Loss) [$ millions] Quarter Quarter 2007 2006 2007 2006 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Gas Distribution 61.4 39.5 464.0 376.0 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Electric Services 44.3 62.4 42.8 127.3 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Energy Investments 5.5 3.7 10.5 6.7 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Energy Services 2.0 2.0 3.4 1.6 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Total Operating Segments 113.2 107.6 520.7 511.6 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Other 20.2 (0.1) 12.2 (15.0) ---- ----- ---- ------ - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Total Operating Income 133.4 107.5 532.9 496.6 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Key Operating Income Drivers by Segment o The Gas Distribution segment, which serves New York City, Long Island and New England, reported second quarter operating income of $61.4 million, an increase of $21.9 million or 55% over the same period last year. This period benefited from increased demand, new customer additions and improved pricing in the interruptible market. Year-to-date results of $464 million were $88 million or 23% higher than last year, again benefiting from increased customer demand due to the colder weather in the first half of the year, new customer additions and increased margins in our interruptible heating market. Net revenues for the year increased $97.4 million, offset in part, by $10 million in higher operating expenses. Weather for the first half of the year was 4-5% colder than normal in all our territories, and 18% and 9% colder than last year for our New York and New England service territories, respectively. Due to our strong marketing efforts, the Company continued to add customers in the first half of 2007 as KeySpan completed approximately 18,500 gas installations, ahead of plan, which should add approximately $20 million in new gross profit margin. This puts us on track to meeting our goal of $50 million in new gross profit margin. 2 o The Electric Services segment owns and operates generation in the New York City and Long Island "load pockets" and manages the Long Island Power Authority's transmission and distribution system under long-term contracts. This segment reported operating income of $44.3 million for the second quarter, a decrease of $18.1 million from last year. This was due, in part, to lower net energy and capacity revenues of $7.6 million from the Ravenswood generating plant, resulting primarily from new generating capacity added in New York City and lower hedging gains. In addition, the realized gain on the financial capacity swap, entered into in May 2006, was an expected $3.2 million lower than last year. The remaining decrease in operating income reflects higher operation expenses. Year-to-date results of $42.8 million were $84.5 million lower than the same period last year. This reduction in operating income reflects lower net energy and capacity revenues of $61.1 million from the Ravenswood generating plant, primarily from lower hedging gains in the energy market and the addition of 1000 MW of new generation in the New York City market. The energy margins in 2006 benefited from large oil to gas price differentials and the dual fuel nature of the Ravenswood plant. In addition, the realized gain on the financial capacity swap was an expected $13.1 million lower than last year. The remaining decrease in operating income reflects higher operation expenses. o The Energy Investments segment reported operating income of $10.5 million for the first half of 2007, compared to $6.7 million in 2006. This segment includes the Company's complementary assets in natural gas pipelines, storage and other energy related investments as well as our Seneca Upshur gas exploration and production operations. These results primarily reflect higher earnings from TransGas, the LNG trucking operations, due to colder weather in the first half of the year and from equity investments as well as lower expenses. o The Energy Services segment includes companies that provide energy related services to homes and businesses in the New York City and Boston metropolitan areas. This segment reported an operating profit of $3.4 million for the first half of 2006, as compared to $1.6 million for the same period last year. This improved performance reflects higher profits in our communications business as well as lower expenses. o The "Other" category reported an increase in operating income of $20.3 million for the second quarter and $27.2 million year-to-date compared to last year. This was primarily due to a decrease in costs at the holding company level including those related to the National Grid transaction, corporate advertising and employee benefit costs that are not allocated to the KeySpan operating segments. 3 Financial Update The Company was able to keep interest expense flat on a year-to-date basis, excluding the one time benefit of $6 million associated with the 2006 favorable tax resolution associated with our New York City Ravenswood facility. This reflects the refinancing efforts of the Company over the past several years. This has resulted in a fixed to float debt ratio of over 90%. At the end of the second quarter of 2007, the Company's debt-to-total-capitalization was 49.4%, reflecting our continued strong financial position. As previously announced, the Company declared a quarterly common stock dividend of $0.475 per share, payable August 1, 2007, to shareholders of record as of July 11, 2007. This dividend payment reflects an annual increase of $0.04 per share over last year's dividend, and is the Company's 37th consecutive period of paying a dividend as KeySpan. The annual dividend rate of $1.90 per share is supported by the Company's strong cash flows and provides a yield to shareholders of approximately 4.5%. Pro-Rata Dividend In anticipation of the close of the transaction between National Grid and KeySpan, the Board of Directors approved the payment of a pro-rata dividend to shareholders of record one business day prior to the transaction close date with National Grid. The amount of such dividend will be based on the number of days elapsed between July 9, 2007 (ex-dividend date), up to but not including the closing date. Assuming the merger closes on August 24th, a pro-rata dividend payment of 23.7 cents per share will be made to KeySpan shareholders. - -------------------------------------------------------------------------------- A member of the Standard & Poor's 500 Index, KeySpan Corporation (NYSE:KSE) is the largest distributor of natural gas in the Northeast, operating regulated gas utilities in New York, Massachusetts, and New Hampshire that serve 2.6 million customers.
