Exhibit 99.1 KEYSPAN NEWS - -------------------------------------------------------------------------------- KeySpan Corporation For Immediate Release Contacts: Investors Media Relations George Laskaris 718.403.2503 718.403.2526 KeySpan Announces Increased Earnings Results for 2006 ----------------------------------------------------- National Grid and KeySpan Transaction Continues to Move Forward Company Raised Annual Dividend to $1.90 per Share Brooklyn, New York, February 22, 2007 - KeySpan Corporation (NYSE: KSE) announced consolidated earnings of $434.2 million or $2.48 per share for 2006, compared to $388.0 million or $2.28 per share for 2005, a 9% increase in earnings per share. These results reflect strong operational performance in the face of a very warm winter and very cool summer as well as the addition of new generation capacity in the New York City market. In addition, the 2006 results include lower interest and tax expense as well as incremental merger costs of $27.1 million, primarily reflecting investment banking and other related fees. For the quarter ending December 31, 2006, consolidated earnings were $126.5 million or $0.72 per share, as compared to $114.8 million or $0.66 per share for the same period last year, a 9% increase in earnings per share. These results were driven by lower operating expenses in the gas business, as well as lower consolidated tax expense. "I am very pleased with the results we were able to achieve in 2006", said Mr. Catell, Chairman and CEO. "Despite the extremely warm winter weather experienced in both our heating seasons, the Company met its goal of achieving $50 million in new gross profit margin in our gas business, again reinforcing the strength of our marketing program and demonstrating the organic growth potential in our service territories. Our electric business, although impacted by increased competition in the New York City market, performed exceptionally well with summer plant availability in excess of 95%. In addition, we continued to maintain our strong financial position with increased cash flows and a debt to total capitalization ratio of approximately 50%." The previously announced acquisition of KeySpan by National Grid continues to move forward. National Grid and KeySpan have received all the necessary approvals, except for the New York State Public Service Commission and the New Hampshire Public Utilities Commission. Procedural schedules have been set in both states and the regulatory proceedings are well underway on the merger and rate plans. "I am very happy with the approval progress made during 2006 for our transaction with National Grid," said Mr. Catell. "We are working very diligently with the New York and New Hampshire state regulatory commissions to receive approval for this transaction. The integration teams from both companies continue to work well together and have made significant progress in developing organizational structures which will complement the strategies of the combined entity. The selection of the senior management team is well underway. We look forward to completing the transaction with National Grid by the middle of this year." It should be noted the 2005 results include a loss of $1.8 million or $0.01 per share from discontinued operations, representing the sale of the mechanical contracting companies in the first half of 2005, and the non-cash charge of $6.6 million or $0.04 per share due to the change in accounting principle from the implementation of FIN 47 (Accounting for Conditional Asset Obligations). Segment Highlights Results in 2006 and 2005 are reported on an Operating Income basis as follows: - -------------------------------------------------------------- ------------ ------------- ------------ ------------ 4th 4th YTD 2006 YTD 2005 Operating Income / (Loss) [$ millions] Quarter Quarter -------------------------------------- 2006 2005 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Gas Distribution 203.5 188.9 568.6 565.7 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Electric Services 21.2 76.0 293.0 342.3 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Energy Investments 4.1 4.0 15.5 20.6 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Energy Services 0.8 4.0 5.3 (2.7) - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Total Operating Segments 229.6 272.9 882.4 925.9 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Other (34.4) (9.8) (54.9) (18.1) ------ ----- ------ ------ - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Total Operating Income 195.2 263.1 827.5 907.8 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ 2006 Weather Operating income results for 2006 were heavily impacted by the very unusual winter and summer weather we incurred. In terms of heating degree days, the first and fourth quarter heating seasons were 15% and 20% warmer than the same periods last year, respectively, while summer weather was 25% cooler than that experienced in the prior year. Key Operating Income Drivers by Segment o The Gas Distribution segment with 2.6 million customers serves New York City, Long Island and New England, and reported operating income for 2006 of $568.6 million, an increase of $2.9 million compared to last year. This increase was realized in spite of the extremely warm weather noted above and lower customer usage due to the high gas price environment. These items reduced net revenues by $51.7 million compared to 2005. This decrease was offset by lower operating expenses of $54.7 million, primarily due to a decrease in uncollectibles. It should be noted that these results include $57 million from the weather normalization adjustments and $9.1 million from weather hedges put in place. The Company continued to add new customers as it completed 48,000 gas installations during 2006. o The Electric Services segment owns and operates 6,650MW of generation in the New York City and Long Island "load pockets", while also managing the Long Island Power Authority's transmission and distribution system under long-term contracts. This segment reported operating income of $293 million for 2006, a decrease of $49.3 million, compared to 2005. These results were 2 heavily impacted by the addition of 1000MW of new generation in the New York City market, resulting in a decrease in capacity revenues of $80.5 million compared to last year. In addition, net energy revenues decreased by $29.8 million compared to last year, due to a combination of the cool summer weather noted earlier and the additional generation capacity. In terms of our LIPA contracts, operating income improved by $11 million primarily due to an increase in off system sales and a reduction in plant overhaul expenses. In addition, a $46.5 million gain on the financial capacity swap was recorded. As reported in previous quarters, KeySpan entered into a financial capacity transaction with Morgan Stanley for a three year period starting May 1, 2006, which settles on a monthly basis. o The Energy Investments segment reported operating income of $15.5 million for 2006, compared to $20.6 million for 2005. This segment includes the Company's complementary assets in natural gas pipelines, storage and other energy related investments as well as production and development investments. These results primarily reflect lower earnings from the Iroquois gas pipeline system and from our LNG trucking operations. It should be noted 2005 results included the earnings from the Premier Pipeline Company of Northern Ireland which was sold in 2005. o The Energy Services segment achieved an operating profit of $5.3 million compared to a loss of $2.7 million last year. This improved performance reflects higher profits and operating margins in our engineering and services businesses as well as in the Company's fiber optic operations. This segment includes companies that provide energy related services to homes and businesses in the New York City and Boston metropolitan areas. Financial Update During 2006, the Company maintained its strong financial position. Despite a rising interest rate environment, the Company was able to reduce interest expenses by $13.2 million to $256.1 million compared to the same period last year. Resolution of a New York City tax case related to the Ravenswood generating facility resulted in half of this savings with the remaining coming from improved capital performance. This is based on the Company's reduction of outstanding debt the past several years as well as the refinancing of debt to lock in favorable interest rates. At year end, the debt to capitalization ratio decreased to 49.9% from 50.7% at the end of 2005 on a GAAP basis, reinforcing KeySpan's "A" quality credit rating. In addition, cash flow from operations increased $655.3 million compared to last year due to favorable working capital requirements, which benefited from improved collections and lower priced gas in storage, and from lower tax payments. Two issues were resolved with the IRS regarding tax returns from 1996 to 1999 for predecessor companies. As a result of this settlement and the settlement with New York City, KeySpan realized a tax benefit of $51.6 million. During the fourth quarter, KeySpan's New York and Long Island gas distribution utilities issued $500 million in senior unsecured notes in a private placement at a rate of 5.6% with a maturity date of 2016. The proceeds were used to replace current short term borrowings and for general working capital purposes. 3 The Company declared an increased quarterly common stock dividend of $0.475 per share, payable February 1, 2007, to shareholders of record as of January 12, 2007. This is the Company's third year of a dividend increase, as well as the 35th consecutive quarter of paying a dividend, building upon its long-standing commitment of dividend payments to its shareholders. The new annual dividend rate of $1.90 per share provides a yield of approximately 4.6%. - -------------------------------------------------------------------------------- Investors are invited to listen to the KeySpan Corporation 2006 Year End Earnings Conference Call on: Thursday, February 22, 2007, at 9:30 AM (EST) Live Dial-in: (800) 500-0311 International Dial-in: (719) 457-2698 Replay will begin two hours after completion of the call until 3/1/06 Replay Number: (888) 203-1112 International Replay Number: (719) 457-0820 Access Code: 2246531 The replay will begin two hours after the call.
