On March 31, 2014, Leidos Holdings, Inc. (the “Company”) entered into an accelerated stock repurchase agreement (the “ASR Agreement”) with Citibank, N.A. (“Citibank”) under which the Company will repurchase shares of its common stock with an aggregate value of approximately $200 million. The Company will acquire these common shares as part of its existing share repurchase authorization.

Under the ASR Agreement, the Company will pay an initial purchase price of $200 million to Citibank on April 1, 2014. Shares will be delivered to the Company over the term of the ASR Agreement. The total number of shares to ultimately be purchased by the Company under the ASR Agreement will generally be based on the average of the daily volume weighted average prices of the Company’s common stock during the term of the Agreement. Upon final settlement of the ASR Agreement, the Company may be entitled to receive additional shares of the Company’s common stock from Citibank or, under certain circumstances specified in the ASR Agreement, the Company may be required to deliver shares or make a cash payment, at its option, to Citibank. The ASR Agreement is scheduled to expire in approximately three months, but may conclude earlier at Citibank’s option, and may be terminated early upon the occurrence of certain events.

A copy of the press release announcing the ASR Agreement is furnished with this report as Exhibit 99.1. The information contained in this report, including Exhibit 99.1, shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (Exchange Act), or otherwise subject to the liabilities of that section, and shall not be incorporated by reference into any registration statement or other document filed under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
