Investor Presentation June 2017 Fiscal year 2017 Full year and Fourth quarter Exhibit 99.1

Disclaimer 1 Forward Looking Safe Harbor Statement Certain statements contained in this presentation and in related comments by our management include “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 forecasted revenue, Diluted EPS, and Adjusted Diluted EPS, future quarterly dividends, and future improvements in operating margins, 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. A number of important factors could cause actual results to differ materially from those contained in or implied by these forward-looking statements, including those factors discussed in our filings with the Securities and Exchange Commission (SEC), including our Annual Report on Form 10-K for the fiscal year ended March 31, 2017, which can be found at the SEC’s website at www.sec.gov. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the foregoing cautionary statements. All such statements speak only as of the date made and, except as required by law, we undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Note Regarding Non-GAAP Financial Data Information Booz Allen discloses in the following information Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin, 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 (i) evaluate each adjustment in our reconciliation of revenue to Revenue Excluding Billable Expenses, operating income to Adjusted Operating Income, net income to Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income and Adjusted Diluted Earnings Per Share, and net cash provided by operating activities to Free Cash Flow, and the explanatory footnotes regarding those adjustments, each as defined under GAAP, (ii) use Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, and Adjusted Diluted EPS in addition to, and not as an alternative to revenue, operating income, net income or diluted EPS as measures of operating results, and (iii) use Free Cash Flow in addition to and not as an alternative to net cash provided by operating activities as a measure of liquidity, each as defined under GAAP. The Financial Appendix includes a reconciliation of Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow to the most directly comparable financial measure calculated and presented in accordance with GAAP. Booz Allen presents these supplemental performance measures because it believes that these measures provide investors and securities analysts with important supplemental information with which to evaluate Booz Allen’s performance, long term earnings potential, or liquidity, as applicable and to enable them to assess Booz Allen’s performance on the same basis as management. 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. With respect to our expectations under “Fiscal 2018 Full Year Outlook” on slide 17, reconciliation of Adjusted Diluted EPS guidance to the closest corresponding GAAP measure is not available without unreasonable efforts on a forward-looking basis due to our inability to predict our stock price, equity grants and dividend declarations during the course of fiscal 2018. Projecting future stock price, equity grants and dividends to be declared would be necessary to accurately calculate the difference between Adjusted Diluted EPS and GAAP EPS as a result of the effects of the two-class method and related possible dilution used in the calculation of EPS. Consequently, any attempt to disclose such reconciliation would imply a degree of precision that could be confusing or misleading to investors. We expect the variability of the above charges to have an unpredictable, and potentially significant, impact on our future GAAP financial results.

Non-gaap financial information “Revenue, Excluding Billable Expenses" represents revenue less billable expenses. We use Revenue, Excluding Billable Expenses because it provides management useful information about the company's operating performance by excluding the impact of costs that are not indicative of the level of productivity of our consulting staff headcount and our overall direct labor, which management believes provides useful information to our investors about our core operations. "Adjusted Operating Income" represents operating income before: (i) adjustments related to the amortization of intangible assets resulting from the acquisition of our Company by the Carlyle Group, and (ii) transaction costs, fees, losses, and expenses, including fees associated with debt prepayments. We prepare Adjusted Operating Income to eliminate the impact of items we do not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary, or non-recurring nature or because they result from an event of a similar nature. "Adjusted EBITDA” represents net income before income taxes, net interest and other expense and depreciation and amortization and before certain other items, including transaction costs, fees, losses, and expenses, including fees associated with debt prepayments. “Adjusted EBITDA Margin” is calculated as Adjusted EBITDA divided by revenue. Booz Allen prepares Adjusted EBITDA and Adjusted EBITDA Margin to eliminate the impact of items it does not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary or non-recurring nature or because they result from an event of a similar nature. "Adjusted Net Income" represents net income before: (i) adjustments related to the amortization of intangible assets resulting from the acquisition of our Company by the Carlyle Group, (ii) transaction costs, fees, losses, and expenses, including fees associated with debt prepayments, (iii) amortization or write-off of debt issuance costs and write-off of original issue discount, and (iv) release of income tax reserves, in each case net of the tax effect where appropriate calculated using an assumed marginal tax rate. We prepare Adjusted Net Income to eliminate the impact of items, net of tax, we do not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary, or non-recurring nature or because they result from an event of a similar nature. "Adjusted Diluted EPS" represents diluted EPS calculated using Adjusted Net Income as opposed to net income. Additionally, Adjusted Diluted EPS does not contemplate any adjustments to net income as required under the two-class method as disclosed in the footnotes to the financial statements. "Free Cash Flow" represents the net cash generated from operating activities less the impact of purchases of property and equipment.

Non-gaap financial information (a) Reflects amortization of intangible assets resulting from the acquisition of our Company by The Carlyle Group. (b) Reflects debt refinancing costs incurred in connection with the refinancing transaction consummated on July 13, 2016.
