Disclaimers Forward Looking Safe Harbor Statement The following information includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Examples of forward-looking statements include information concerning Booz Allen’s preliminary financial results, financial outlook and guidance, including projected Revenue, Diluted EPS, and Adjusted Diluted EPS, as well as any other statement that does not directly relate to any historical or current fact. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “could,” “should,” “forecasts,” “expects,” “intends,” “plans,” “anticipates,” “projects,” “outlook,” “believes,” “estimates,” “predicts,” “potential,” “continue,” “preliminary,” or the negative of these terms or other comparable terminology. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we can give you no assurance these expectations will prove to have been correct. These forward-looking statements relate to future events or our future financial performance and involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to differ materially from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements. These risks and other factors include: cost cutting and efficiency initiatives, budget reductions, Congressionally mandated automatic spending cuts, and other efforts to reduce U.S. government spending, including automatic sequestration required by the Budget Control Act of 2011 (as amended by the American Taxpayer Relief Act of 2012 and the Consolidated Appropriations Act, 2014), which have reduced and delayed contract awards and funding for orders for services especially in the current political environment or otherwise negatively affect our ability to generate revenue under contract awards, including as a result of reduced staffing and hours of operation at U.S. government clients; delayed funding of our contracts due to uncertainty relating to and a possible failure of Congressional efforts to craft a long-term agreement on the U.S. government’s ability to incur indebtedness in excess of its current limits prior to February 7, 2014, the date on which legislation relating to the U.S. government’s debt limit expires, or changes in the pattern or timing of government funding and spending (including those resulting from or related to cuts associated with sequestration or other budgetary cuts made in lieu of sequestration); current and continued uncertainty around the timing, extent, nature, and effect of Congressional and other U.S. government action to address budgetary constraints, including, but not limited to, uncertainty around the outcome of Congressional efforts to craft a long-term agreement on the U.S. government’s ability to incur indebtedness in excess of its current limits, and the U.S. deficit; any issue that compromises our relationships with the U.S. government or damages our professional reputation, including negative publicity concerning government contractors in general or us in particular; changes in U.S. government spending, including a continuation of efforts by the U.S. government to decrease spending for management support service contracts, and mission priorities that shift expenditures away from agencies or programs that we support; the size of our addressable markets and the amount of U.S. government spending on private contractors; failure to comply with numerous laws and regulations; our ability to compete effectively in the competitive bidding process and delays or losses of contract awards caused by competitors' protests of major contract awards received by us; the loss of General Services Administration Multiple Award schedule contracts, or GSA schedules, or our position as prime contractor on government-wide acquisition contract vehicles; changes in the mix of our contracts and our ability to accurately estimate or otherwise recover expenses, time, and resources for our contracts; our ability to generate revenue under certain of our contracts; our ability to realize the full value of and replenish our backlog and the timing of our receipt of revenue under contracts included in backlog; changes in estimates used in recognizing revenue; an inability to attract, train, or retain employees with the requisite skills, experience, and security clearances; an inability to hire, assimilate, and deploy enough employees to serve our clients under existing contracts; an inability to timely and effectively utilize our employees; failure by us or our employees to obtain and maintain necessary security clearances; the loss of members of senior management or failure to develop new leaders; misconduct or other improper activities from our employees or subcontractors, including the improper use or release of our clients' sensitive or classified information; increased insourcing by various U.S. government agencies due to changes in the definition of “inherently governmental” work, including proposals to limit contractor access to sensitive or classified information and work assignments; increased competition from other companies in our industry; failure to maintain strong relationships with other contractors; inherent uncertainties and potential adverse developments in legal or regulatory proceedings, including litigation, audits, reviews, and investigations, which may result in materially adverse judgments, settlements, withheld payments, penalties, or other unfavorable outcomes including debarment, as well as disputes over the availability of insurance or indemnification; continued efforts to change how the U.S. government reimburses compensation related and other expenses or otherwise limit such reimbursements, including recent rules that expand the scope of existing reimbursement limitations, such as a reduction in allowable annual employee compensation to certain contractors as a result of the Bipartisan Budget Act of 2013, and an increased risk of compensation being deemed unallowable or payments being withheld as a result of U.S. government audit, review or investigation; internal system or service failures and security breaches, including, but not limited to, those resulting from external cyber attacks on our network and internal systems; risks related to changes to our operating structure, capabilities, or strategy intended to address client needs, grow our business or respond to market developments; risks associated with new relationships, clients, capabilities, and service offerings in our U.S. and international businesses; failure to comply with special U.S. government laws and regulations relating to our international operations; risks related to our indebtedness and credit facilities which contain financial and operating covenants; the adoption by the U.S. government of new laws, rules, and regulations, such as those relating to organizational conflicts of interest issues or limits; risks related to completed and future acquisitions, including our ability to realize the expected benefits from such acquisitions; an inability to utilize existing or future tax benefits, including those related to our stock-based compensation expense, for any reason, including a change in law; variable purchasing patterns under U.S. government GSA schedules, blanket purchase agreements and indefinite delivery, indefinite quantity contracts. Additional information concerning these and other factors can be found in our filings with the Securities and Exchange Commission (SEC), including our Annual Report on Form 10-K, filed with the SEC on May 23, 2013.

Note Regarding Non-GAAP Financial Data Information Booz Allen discloses in the following information Adjusted Operating Income, Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow which are not recognized measurements under GAAP, and when analyzing Booz Allen’s performance or liquidity as applicable, investors should (i) evaluate each adjustment in our reconciliation of Operating and Net Income to Adjusted Operating Income, Adjusted EBITDA and Adjusted Net Income, and cash flow to free cash flow, and the explanatory footnotes regarding those adjustments, and (ii) use Adjusted EBITDA, Adjusted Net Income, Adjusted Operating Income, and Adjusted Diluted EPS in addition to, and not as an alternative to operating income, net income or Diluted EPS as a measure of operating results with cash flow in addition to and not as an alternative to net cash generated from operating activities as a measure of liquidity, each as defined under GAAP. The Financial Appendix includes a reconciliation of Adjusted Operating Income, Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow to the most directly comparable financial measure calculated and presented in accordance with GAAP.

These supplemental performance and liquidity measurements may vary from and may not be comparable to similarly titled measures by other companies in Booz Allen’s industry. 2
