LOS ANGELES, Nov. 21, 2002 -- Northrop Grumman Corporation (NYSE:NOC) announced today updated financial guidance with respect to future sales, segment operating margin rates, economic earnings per share and cash from operations in 2003, 2004 and 2005. The updated guidance reflects the proposed acquisition of TRW, Inc. (NYSE:TRW) including the initial issuance of approximately 70 million shares of Northrop Grumman common stock in the transaction, the sale of TRW's automotive business to The Blackstone Group and the effect of Northrop Grumman's discontinued operations.

In meetings commencing today, senior management from both companies will be discussing the updated financial outlook and the benefits of the proposed merger with sell side analysts and institutional shareholders of both companies. Special shareholder meetings to approve the merger have been scheduled by Northrop Grumman and TRW on Dec. 11, 2002.

The company issued the following guidance:

  -- Sales in 2003 are expected to be $25 billion to $26 billion; 
 -- Double-digit sales growth is expected in 2004 and 2005;
 -- Segment operating margin rate is expected to be approximately 8.5
    percent in 2003, increasing to nearly 9 percent by 2004 and
    approaching 10 percent by 2005;  
 -- The company expects 15 percent to 20 percent growth in economic
    earnings per share from a range of $6.10 to $6.20 in 2002, to
    $7.00 to $7.50 in 2003.  The company expects double-digit growth
    for 2004 resulting in a range of $7.90 to $8.40.  Double-digit
    growth in economic earnings per share is also expected for 2005.
 -- Cash from operations in 2003 is expected to be approximately $1
    billion (before a $1 billion B-2 tax payment in the first quarter
    of 2003), more than $1.5 billion in 2004 and approximately $2
    billion in 2005;
 -- Importantly, the company expects pro forma net debt to total
    capital of approximately 26 percent after the close of the TRW
    transaction and the sale of the TRW Automotive business.  Net debt
    to total capitalization is expected to be approximately 26 percent
    at year-end 2003, 20 percent at year-end 2004 and 13 percent at
    year-end 2005.

Kent Kresa, Northrop Grumman chairman and chief executive officer, stated, "We look forward to meeting with the investment community to talk about the enormous benefits of the combination of Northrop Grumman and TRW. This acquisition is the culmination of the transformation we began in 1994. The new Northrop Grumman offers shareholders participation in the growth of a new powerhouse defense company with outstanding programs and a strong position for the future. The acquisition of TRW and the sale of its automotive business strengthen our balance sheet and provide financial flexibility and outstanding growth prospects."
