©2016 LEIDOS. ALL RIGHTS RESERVED. Forward-Looking Statements The forward looking statements contained in this document involve risks and uncertainties that may affect Leidos Holdings, Inc.’s (“Leidos”) operations, markets, products, services, prices and other factors as discussed in filings with the Securities and Exchange Commission (the “SEC”). These risks and uncertainties include, but are not limited to, economic, competitive, legal, governmental and technological factors. Accordingly, there is no assurance that the expectations of Leidos will be realized. This document also contains statements about the proposed business combination transaction between Leidos and Lockheed Martin Corporation (“Lockheed Martin”), in which Lockheed Martin will separate a substantial portion of its government information technology infrastructure services business and its technical services business, which have been realigned in the Information Systems & Global Solutions (IS&GS) business segment, and combine this business with Leidos in a Reverse Morris Trust transaction (the “Transaction”). Many factors could cause actual results to differ materially from these forward-looking statements with respect to the Transaction, including risks relating to the completion of the transaction on anticipated terms and timing, including obtaining stockholder and regulatory approvals, anticipated tax treatment, the dependency of any split-off transaction on market conditions and the value to be received in any split-off transaction, unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses, future prospects, business and management strategies for the management, expansion and growth of the new combined company’s operations, Leidos’ ability to integrate the businesses successfully and to achieve anticipated synergies, and the risk that disruptions from the Transaction will harm Leidos’ business. While the list of factors presented here is considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on Leidos’ consolidated financial condition, results of operations or liquidity. For a discussion identifying additional important factors that could cause actual results to vary materially from those anticipated in the forward-looking statements, see Leidos’ filings with the SEC, including the prospectus included in the registration statement on Form S-4, the prospectus filed by Leidos pursuant to Rule 424(b)(3), Leidos' definitive proxy statement for its annual meeting of stockholders, as well as “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” in Leidos’ annual report on Form 10-K for the period ended January 1, 2016, its Quarterly Reports filed on Form 10-Q, and such other filings that Leidos makes with the SEC from time to time, which are available at http://www.Leidos.com and at the SEC’s web site at http://www.sec.gov. Leidos assumes no obligation to provide revisions or updates to any forward-looking statements should circumstances change, except as otherwise required by securities and other applicable laws. Additional Information and Where to Find It In connection with the proposed transaction, Abacus Innovations Corporation, a wholly-owned subsidiary of Lockheed Martin created for the Transaction (“Spinco”), has filed with the SEC, and the SEC declared effective on July 11, 2016, a registration statement on Form S-4/S-1 containing a prospectus, and Leidos has filed with the SEC, and the SEC declared effective on July 11, 2016, a registration statement on Form S-4 containing a prospectus, and Leidos has filed with the SEC a definitive proxy statement on Schedule 14A.
