Northrop Grumman Board Approves Spin-Off of Huntington Ingalls Industries

LOS ANGELES – March 15, 2011 – Northrop Grumman Corporation (NYSE:NOC) today announced that its board of directors has approved the spin-off of its wholly owned subsidiary, Huntington Ingalls Industries, Inc. (HII), to Northrop Grumman stockholders, subject to final U.S. Securities and Exchange Commission (SEC) clearance, and set the distribution ratio, record date and distribution date for the spin-off.

"We have determined that a spin-off of our shipbuilding business will best serve our shareholders, customers and employees. The separation will enable HII and Northrop Grumman to focus more intently on their respective customers," said Wes Bush, chief executive officer and president.

The Northrop Grumman board of directors approved a pro rata dividend of HII common stock owned by Northrop Grumman on March 31, 2011, (the "distribution date") to Northrop Grumman stockholders of record as of the close of business of the New York Stock Exchange (NYSE) on March 30, 2011, (the "record date"). On the distribution date, Northrop Grumman stockholders of record will receive one share of HII for every six shares of Northrop Grumman common stock they hold. No fractional shares of HII common stock will be distributed. Fractional shares of HII common stock will be aggregated and sold in the open market, and the aggregate net proceeds of the sales will be distributed ratably in the form of cash payments to Northrop Grumman stockholders of record who would otherwise be entitled to receive a fractional share of HII common stock.
