LOS ANGELES -- Jan. 25, 2007 -- Northrop Grumman Corporation (NYSE:NOC) reported that fourth quarter 2006 income from continuing operations rose 37 percent to $457 million, or $1.29 per diluted share, from $334 million, or $0.93 per diluted share, in the fourth quarter of 2005. Income from continuing operations for 2006 increased 13 percent to $1.6 billion, or $4.44 per diluted share, from $1.4 billion, or $3.83 per diluted share, in 2005.

Sales for the 2006 fourth quarter increased 5 percent to $8 billion from $7.7 billion in the 2005 fourth quarter. Sales for 2006 totaled $30.1 billion and are comparable to 2005. Fourth quarter and full year operating results for 2006 and 2005 reflect the reclassification of certain operations from continuing to discontinued operations.

Cash from operations for the 2006 fourth quarter totaled $309 million compared with $660 million in the 2005 fourth quarter, and cash from operations for the year totaled $1.8 billion compared with $2.6 billion in 2005. Contract acquisitions in the 2006 fourth quarter increased 90 percent, to $12.2 billion. For all of 2006, contract acquisitions increased 58 percent to $38.8 billion, bringing funded backlog to $30.5 billion and total backlog to a record $61 billion at Dec. 31, 2006.

"Our focus on performance generated another strong quarter and our fourth consecutive year of double-digit growth in earnings per share. Together, our four businesses achieved solid double-digit growth in operating margin and outstanding cash generation, for both the quarter and the year," said Ronald D. Sugar, Northrop Grumman chairman and chief executive officer. "Our focus on operating margin rate improvement resulted in an expansion of 80 basis points in operating margin rate in 2006 compared with 2005," he added.

"For 2007, we are targeting solid earnings growth driven by higher sales and improving margin rates. Northrop Grumman's financial position continues to strengthen. Our record backlog gives us the foundation for future sales growth, and our outstanding balance sheet supports a cash deployment strategy that invests for the future and returns cash to shareholders through dividends and share repurchases," Sugar concluded.

2007 Guidance

The company expects 2007 sales to range between $31 and $32 billion. Earnings per diluted share from continuing operations are expected to range between $4.80 and $5.05, and include estimated net pension income of approximately $70 million. The company's estimated pension expense for 2007 is based on a composite discount rate of 6 percent and a long-term expected rate of return on plan assets of 8.5 percent. The company's 2006 discount rate was 5.75 percent. Net cash provided by operating activities is expected to range between $2.5 billion and $2.8 billion in 2007.

Fourth Quarter 2006 Results

Fourth quarter 2006 sales rose 5 percent to $8 billion compared with $7.7 billion in the 2005 fourth quarter.

Total segment operating margin rose 13 percent and includes double-digit percentage increases in operating margin in Information & Services, Electronics and Ships. Total operating margin for the 2006 fourth quarter increased 15 percent to $622 million from $539 million for the 2005 fourth quarter. Fourth quarter 2006 includes a $61 million pre-tax forward loss provision for the Multi-role Electronically Scanned Array (MESA) radar system fixed price development programs.

Other income for the 2006 fourth quarter increased to $134 million from $17 million for the same period of 2005. The increase includes a $111 million pre-tax gain on the sale of approximately 9.7 million shares of TRW Automotive common stock.

Federal and foreign income taxes for the 2006 fourth quarter increased to $230 million from $131 million in the fourth quarter of 2005. The increase is primarily attributable to higher income in the 2006 fourth quarter. In addition, the fourth quarter of 2005 included a $20 million net tax benefit related to the settlement of prior years IRS appeals cases. The effective tax rate applied to income from continuing operations for the 2006 fourth quarter was 33.5 percent compared with 28.2 percent in the 2005 fourth quarter.

Earnings per share are based on weighted average diluted shares outstanding of 359 million for the fourth quarter of 2006 and 358.1 million for the fourth quarter of 2005. Fourth quarter 2006 weighted average shares outstanding include the dilutive impact of the company's Series B mandatorily redeemable preferred stock.

Weighted average diluted shares outstanding used to calculate earnings per diluted share and earnings per diluted share from continuing operations are adjusted to reflect the assumed conversion of the company's Series B preferred stock if the effect is dilutive. For the fourth quarter of 2006 and the full year 2006, the assumed conversion of these shares was dilutive, and earnings per share amounts were adjusted to include the effects of an additional 6.4 million shares outstanding and the elimination of dividends on the preferred stock.

Contract acquisitions for the 2006 fourth quarter increased to $12.2 billion from $6.4 billion for the same period of 2005. The increase in contract acquisitions includes higher acquisitions in all four businesses. Fourth quarter 2005 contract acquisitions were impacted by the delay in the passage of the 2006 defense budget. Total backlog, which includes funded backlog and firm orders for which funding is not currently contractually obligated by the customer, was $61 billion at Dec. 31, 2006 compared with $56.2 billion at Dec. 31, 2005.

Electronics fourth quarter 2006 sales increased 4 percent from the prior year period due to higher sales across several areas, including infrared countermeasures, bio-detection equipment, automated flat sorting machines for the U.S. Postal Service, and navigation systems. These increases were partially offset by lower sales for the F-16 Block 60 program, and sales adjustments resulting from the forward loss provisions on the MESA radar system fixed price development program.

Electronics fourth quarter 2006 operating margin increased 21 percent from the prior year period and includes lower expense for amortization of purchased intangibles and improved program performance. Pre-tax forward loss provisions totaling $61 million for the MESA radar system programs (Wedgetail and Peace Eagle), partially offset the lower amortization and improved program performance. Electronics fourth quarter 2005 operating margin included a $65 million pre-tax forward loss provision for the F-16 Block 60 fixed price development program.

Electronics 2006 sales were comparable to 2005 and include lower sales for the F-16 Block 60, MESA radar, and Longbow Missile programs, partially offset by higher sales of automated flat sorting machines to the U.S. Postal Service, vehicle intercommunication systems to the U.S. Army, and infrared countermeasures.

Electronics 2006 operating margin increased 6 percent due to lower expense for the amortization of purchased intangibles and favorable program performance, which was partially offset by forward loss provisions for the MESA and ASPIS II programs.

Ships fourth quarter 2006 sales rose 3 percent from the fourth quarter of 2005 and included higher aircraft carrier sales, primarily driven by higher volume for the USS Carl Vinson refueling program, higher revenue for the Coast Guard's Deepwater program, and continued recovery from the impact of Hurricane Katrina. Ships 2006 sales declined 8 percent from 2005 primarily due to lower sales for the DDG 1000 program (formerly known as the DD(X) program) and continued recovery from the impact of Hurricane Katrina. Sales declines in these programs were partially offset by higher sales for aircraft carrier and Coast Guard programs.

Ships fourth quarter 2006 operating margin increased 14 percent from the fourth quarter of 2005. Ships fourth quarter operating margin includes a pension benefit resulting from the Pension Protection Act of 2006 and improved sales mix, partially offset by lower performance on the LHD program. Ships 2006 operating margin increased 58 percent. Ships operating margin for 2005 included a $150 million pre-tax charge for Hurricane Katrina-related cost growth.
