March 21, 2011 Dear Northrop Grumman Stockholder: I am pleased to inform you that on March 14, 2011, the board of directors of Northrop Grumman Corporation approved the spin-off of Huntington Ingalls Industries, Inc., a wholly owned subsidiary of Northrop Grumman. Upon completion of the spin-off, Northrop Grumman stockholders will own 100% of the outstanding shares of common stock of HII. At the time of the spin-off, HII will own and operate our shipbuilding business, which has been designing, building, overhauling and repairing a wide variety of ships primarily for the U.S. Navy and the U.S. Coast Guard for over a century. We believe that this separation of HII to form a new, independent, publicly owned company is in the best interests of both Northrop Grumman and HII. The spin-off will be completed by way of a pro rata distribution of HII common stock to our stockholders of record as of 5:00 p.m., Eastern time, on March 30, 2011, the spin-off record date. Each Northrop Grumman stockholder will receive one share of HII common stock for every six shares of Northrop Grumman common stock held by such stockholder on the record date. The distribution of these shares will be made in book-entry form, which means that no physical share certificates will be issued. Following the spin-off, stockholders may request that their shares of HII common stock be transferred to a brokerage or other account at any time. No fractional shares of HII common stock will be issued. If you would otherwise have been entitled to a fractional common share in the distribution, you will receive the net cash proceeds of such fractional share instead. The spin-off is subject to certain customary conditions. Stockholder approval of the distribution is not required, nor are you required to take any action to receive your shares of HII common stock. Immediately following the spin-off, you will own common stock in Northrop Grumman and HII. Northrop Grumman’s common stock will continue to trade on the New York Stock Exchange under the symbol “NOC.” HII intends to have its common stock listed on the New York Stock Exchange under the symbol “HII.” We expect the spin-off to be tax-free to the stockholders of Northrop Grumman, except with respect to any cash received in lieu of fractional shares. The enclosed information statement, which is being mailed to all Northrop Grumman stockholders, describes the spin-off in detail and contains important information about HII, including its historical consolidated financial statements. We urge you to read this information statement carefully. I want to thank you for your continued support of Northrop Grumman. We look forward to your support of HII in the future. Yours sincerely, Wesley G. Bush Chief Executive Officer and President Northrop Grumman March 21, 2011 Dear Huntington Ingalls Industries, Inc. Stockholder: It is our pleasure to welcome you as a stockholder of our company, Huntington Ingalls Industries, Inc. We design, build and maintain nuclear and non-nuclear ships for the U.S. Navy and Coast Guard, and provide aftermarket services for military ships around the globe. For more than a century, we have been building more ships, in more ship classes, than any other U.S. naval shipbuilder. As an independent, publicly owned company, we believe we can more effectively focus on our objectives and satisfy the capital needs of our company, and thus bring more value to you as a stockholder than we could as an operating segment of Northrop Grumman Corporation. We expect to have HII common stock listed on the New York Stock Exchange under the symbol “HII” in connection with the distribution of HII common stock by Northrop Grumman. We invite you to learn more about HII and our subsidiaries by reviewing the enclosed information statement. We look forward to our future as an independent, publicly owned company and to your support as a holder of HII common stock. Very truly yours, C. Michael Petters President and Chief Executive Officer Huntington Ingalls Industries, Inc. INFORMATION STATEMENT HUNTINGTON INGALLS INDUSTRIES, INC. 4101 Washington Avenue Newport News, Virginia 23607 Common Stock (par value $1.00 per share) This information statement is being sent to you in connection with the separation of Huntington Ingalls Industries, Inc. (“HII”) from Northrop Grumman Corporation (“Northrop Grumman”), following which HII will be an independent, publicly owned company. As part of the separation, Northrop Grumman will undergo an internal reorganization, after which it will complete the separation by distributing all of the shares of HII common stock on a pro rata basis to the holders of Northrop Grumman common stock. We refer to this pro rata distribution as the “distribution” and we refer to the separation, including the internal reorganization and distribution, as the “spin-off.” We expect that the spin-off will be tax-free to Northrop Grumman stockholders for U.S. Federal income tax purposes, except to the extent of cash received in lieu of fractional shares. Every six shares of Northrop Grumman common stock outstanding as of 5:00 p.m., Eastern time, on March 30, 2011, the record date for the distribution, will entitle the holder thereof to receive one share of HII common stock. The distribution of shares will be made in book-entry form. Northrop Grumman will not distribute any fractional shares of HII common stock. Instead, the distribution agent will aggregate fractional shares into whole shares, sell the whole shares in the open market at prevailing market prices and distribute the aggregate net cash proceeds from the sales pro rata to each holder who would otherwise have been entitled to receive a fractional share in the spin-off. The distribution will be effective as of 12:01 a.m., Eastern time, on March 31, 2011. Immediately after the distribution becomes effective, we will be an independent, publicly owned company. No vote or further action of Northrop Grumman stockholders is required in connection with the spin- off. We are not asking you for a proxy. Northrop Grumman stockholders will not be required to pay any consideration for the shares of HII common stock they receive in the spin-off, and they will not be required to surrender or exchange shares of their Northrop Grumman common stock or take any other action in connection with the spin-off. All of the outstanding shares of HII common stock are currently owned by Northrop Grumman. Accordingly, there is no current trading market for HII common stock. We expect, however, that a limited trading market for HII common stock, commonly known as a “when-issued” trading market, will develop at least two trading days prior to the record date for the distribution, and we expect “regular-way” trading of HII common stock will begin the first trading day after the distribution date. We intend to list HII common stock on the New York Stock Exchange under the ticker symbol “HII.” In reviewing this information statement, you should carefully consider the matters described in “Risk Factors” beginning on page 22 of this information statement.
