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 Hart Scott Rodino and CFIUS Clearance Brooklyn, New York, August 3, 2006 - KeySpan Corporation (NYSE: KSE) announced consolidated earnings of $49.4 million or $0.28 per share for the second quarter of 2006, as compared to $16.2 million or $0.10 per share for the same period last year. These favorable results reflect higher operating income from the gas distribution segment, as well as lower financing and tax expenses. For the six month period ended June 30, 2006, KeySpan reported consolidated earnings of $257.4 million or $1.47 per share, compared to $250.6 million or $1.51 per share for the same period last year. These year-to-date results reflect increased electric operating income as well as the lower financing and tax expenses noted above, partially offsetting the impact on operating results of the very warm weather experienced during the first quarter of this year in the gas distribution segment. Discontinued operations reflected a loss of $1.8 million or $0.01 per share for the three and six months ended June 30, 2005, respectively as a result of the sale of KeySpan's mechanical contracting business during the first half of 2005. "I am particularly pleased with the solid performance of our core gas distribution business. The Company continues to add new gas customers in all our service territories. In spite of the current relatively high gas price environment, we are on track to achieving our new customer growth in the gas business, with a goal for 2006 of close to $50 million in new gross profit margin," said Robert B. Catell, KeySpan Chairman and Chief Executive Officer. "Our electric business is in top form and ready to meet the ever increasing electric demand experienced by both Long Island and New York City. Our financial condition remains strong with a 47.3% 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 filings and approvals are progressing. KeySpan and National Grid filed a joint merger application with the Federal Energy Regulatory Commission on May 25th. The companies also cleared review by the Federal Trade Commission under the Hart-Scott-Rodino Antitrust Improvements Act on July 10 and the Committee of Foreign Investment in the United States (CFIUS) on July 12. In addition, the merger approval request and long term rate plans for KeySpan's two New York gas distribution utilities were 8 filed with the New York Public Service Commission on July 20 which would provide more than $500 million in savings to New York City, Long Island and upstate customers. Filings with the New Hampshire Public Utilities Commission and the State of New Jersey Board of Public Utilities are expected in the next several weeks. "I am pleased with the progress made by KeySpan and National Grid on the transaction as we have received several approvals and have submitted additional filings," said Mr. Catell. "The integration process commenced in April and both companies are working well together to realize the potential of this transaction. We will work very closely with the state regulatory commissions to receive approval for this transaction which will provide substantial benefits to our customers and investors. We look forward to completing the transaction next year." Segment Highlights Results in 2006 and 2005 are reported on an Operating Income basis as follows: - ------------------------------------------------------------------------------------------------------------------- 2nd 2nd YTD YTD Operating Income / (Loss) [$ millions] Quarter Quarter 2006 2005 -------------------------------------- 2006 2005 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Gas Distribution 39.5 30.4 376.0 422.3 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Electric Services 62.4 65.7 127.3 116.7 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Energy Investments 3.7 5.5 6.7 11.9 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Energy Services 2.0 (2.8) 1.6 (5.6) - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Total Operating Segments 107.6 98.8 511.6 545.3 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Other (0.1) 4.4 (15.0) (3.4) ----- --- ------ ----- - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Total Operating Income 107.5 103.2 496.6 541.9 - -------------------------------------------------------------- ------------ ------------- ------------ ------------ Operating income for the second quarter of 2006 increased $4.3 million or approximately 4%, to $107.5 million, compared to 2005. These results primarily reflect higher earnings from the gas distribution segment from higher net revenues, offset by lower capacity and energy margins at the Ravenswood plant in the electric business. For the first half of 2006, operating income decreased $45.3 million or 8%, to $496.6 million, compared to $541.9 million for the same period last year. The main driver of this decrease was the gas distribution business, which was impacted by the unusually warm weather in the first quarter. This was partially offset by the electric segment which benefited from a financial capacity swap gain. Both the quarter and year to date results also benefited from enhanced profitability in the Energy Services segment. 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 $39.5 million, an increase of $9.1 million over the same period last year, benefiting from increased net gas revenues and improved pricing in the temperature control market. Year-to-date results of $376 million were $46.3 million lower than last year, due to weather in the first quarter which was 15% warmer than last year, substantially higher gas prices and higher operating expenses. In spite of these conditions, the Company continued to add customers in the first half of 2006 as KeySpan completed approximately 19,000 gas installations, consistent with plan, which should add approximately $19 9 million in new gross profit margin. Net revenues for the year decreased $33 million, as the favorable impact of load growth additions was more than offset by lower usage per customer resulting from the warm weather and higher gas prices. The favorable operating results from the second quarter partially offset the impact of weather in the first quarter. In addition, operating expenses increased $13.5 million, primarily due to higher employee benefit related expenses and a larger provision for uncollectible accounts driven by the impact of higher gas prices. 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 $62.4 million for the second quarter, a decrease of $3.3 million, due primarily to lower net energy and capacity revenues from the Ravenswood generating plant, resulting primarily from new generating capacity added in New York City. Earlier in the year, KeySpan entered into a fixed for float unforced capacity financial swap with Morgan Stanley for a three year period, which is settled on a monthly basis. KeySpan realized a gain of $17.7 million on this swap transaction for the quarter, which is reflected in the results for this segment. Year-to-date results of $127.3 million were $10.6 million higher than the same period last year, primarily reflecting the gain from the financial capacity swap. The Ravenswood generating plant experienced a decrease in net revenues of $1 million. o The Energy Investments segment reported operating income of $6.7 million for the first half of 2006, compared to $11.9 million in 2005. 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 lower earnings from KeySpan's investment in the Iroquois gas pipeline system. In addition, 2005 results include the earnings from the Premier pipeline company which was sold in 2005. 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 $1.6 million for the first half of 2006, as compared to a loss of $5.6 million incurred in the same period last year. This improved performance reflects higher gross profit and operating margins in the engineering division and residential equipment installation and service contract business. Financial Update Despite a rising interest rate environment, the Company was able to reduce interest expenses in the second quarter by $13.2 million to $59.4 compared to the same period last year. Part of this reduction was the result of a favorable tax resolution with New York City regarding income taxes relating to the Ravenswood generating facility. As a result of the settlement of this issue, KeySpan reversed a previously recorded $6 million interest reserve. The remaining benefit stems from the Company's reduction of debt outstanding. At the end of the second quarter of 2006, the Company's debt-to-total-capitalization improved to 47.3% from 50.7% at year end 2005, reflecting our continued strong financial position. 10 In addition, 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 $16 million in the second quarter. The Company declared a quarterly common stock dividend of $0.465 per share, payable August 1, 2006, to shareholders of record as of July 12, 2006. This dividend payment reflects an annual increase of $0.04 per share over last year's dividend, and is the Company's 33rd consecutive period of paying a dividend as KeySpan, as the company continues to build upon its long-standing commitment of dividend payments to its shareholders. The annual dividend rate of $1.86 per share is supported by the Company's strong cash flows and provides a yield to shareholders of approximately 4.5%. - -------------------------------------------------------------------------------- Investors are invited to listen to the KeySpan Corporation 2006 2nd Quarter Earnings Conference Call on: Thursday, August 3, 2006 at 10:30 AM (EST) ------------------------------------------ Live Dial-In Number: 866-564-7444 International Dial-In Number: 719-234-0008 Replay will begin two hours after the call ends until 8/7//06 Replay Dial In: 888-203-1112 International Replay: 719-457-0820 Conference ID: 5254836 Audio webcast available at http://investor.keyspanenergy.com 11 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.
