3Copyright © Booz Allen Hamilton Inc. 2025 www.boozallen.com Booz Allen Hamilton Restricted Disclaimer DISCLAIMER 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, Adjusted EBITDA, Diluted EPS, 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, 2025, 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. Booz Allen’s fiscal year ends on March 31 and unless otherwise noted, references to fiscal year, fiscal or FY are for fiscal years ended March 31. Note Regarding Non-GAAP Financial Data Information Booz Allen discloses Revenue, Excluding Billable Expenses, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow, and Net Leverage Ratio, which are not recognized measurements under accounting principles generally accepted in the United States, or GAAP, and when analyzing Booz Allen’s performance or liquidity as applicable, investors should (i) evaluate each adjustment in our reconciliation of revenue to Revenue, Excluding Billable Expenses, net income attributable to common stockholders to Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted Net Income and Adjusted Diluted EPS, net cash used in operating activities to Free Cash Flow, and net debt to Net Leverage Ratio, and the explanatory footnotes regarding those adjustments, each as defined under GAAP, (ii) use Revenue, Excluding Billable Expenses, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted Net Income, and Adjusted Diluted EPS in addition to, and not as an alternative to, revenue, operating income, net income attributable to common stockholders or diluted EPS as measures of operating results, each as defined under GAAP, (iii) use Free Cash Flow in addition to, and not as an alternative to, net cash used in operating activities as a measure of liquidity, each as defined under GAAP, and (iv) use Net Leverage Ratio in addition to, and not as an alternative to, net debt as a measure of Booz Allen's debt leverage. The Appendix includes a reconciliation of Revenue, Excluding Billable Expenses, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow and Net Leverage Ratio 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 “Financial Outlook", reconciliation of Adjusted Diluted EPS guidance, Adjusted EBITDA, and Adjusted EBITDA Margin on Revenue, and Adjusted Effective Tax Rate 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 with respect to Adjusted Diluted EPS, and our net income, net interest and other expenses with respect to Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, and Adjusted Effective Tax Rate, during the course of fiscal 2026. With respect to Adjusted Diluted EPS guidance, 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. For the same reason, a reconciliation of Adjusted EBITDA and Adjusted EBITDA Margin on Revenue guidance for fiscal 2026, of Adjusted EBITDA guidance through fiscal 2026, and of Adjusted Effective Tax Rate guidance through fiscal 2026 to the closest corresponding GAAP measures are not available without unreasonable efforts on a forward-looking basis due to our inability to predict specific quantifications of the amounts that would be required to reconcile such measures. Accordingly, Booz Allen is relying on the exception provided by Item 10(e)(1)(i)(B) of Regulation S-K to exclude these reconciliations.

10Copyright © Booz Allen Hamilton Inc. 2025 www.boozallen.com Booz Allen Hamilton Restricted Non-GAAP Financial Information DISCLAIMER • “Revenue, Excluding Billable Expenses” represents revenue less billable expenses. Booz Allen uses Revenue, Excluding Billable Expenses because it provides management useful information about the Company’s operating performance by excluding the impact of costs such as subcontractor expenses, travel expenses, and other non-labor expenses incurred to perform on contracts. Billable expenses generally have lower margin and thus are less indicative of our profit generation capacity. • "EBITDA” represents net income before income taxes, interest expense, net and other income (expense), net, and depreciation and amortization. • “Adjusted EBITDA” represents net income before income tax expense, interest expense, net and other income (expense), net and depreciation and amortization and before certain other items, including the change in provision for claimed costs for historical rate years, other corporate expenses, financing transaction costs, DC tax assessment adjustment, and insurance recoveries. “Adjusted EBITDA Margin on Revenue” is calculated as Adjusted EBITDA divided by revenue. Booz Allen prepares Adjusted EBITDA and Adjusted EBITDA Margin on Revenue 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) other corporate expenses, (ii) acquisition amortization, and (iii) amortization or write-off of debt issuance costs and debt discount, in each case net of the tax effect where appropriate calculated using an assumed effective tax rate. Booz Allen prepares Adjusted Net Income to eliminate the impact of items, net of tax, 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 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 consolidated financial statements of the Company's Form 10-K for the fiscal year ended March 31, 2025. • "Free Cash Flow" represents the net cash generated from operating activities less the impact of purchases of property, equipment and software. • "Adjusted Effective Tax Rate" represents income tax expense (benefit) excluding the income tax effects of adjustments to net income, divided by adjusted earnings before income tax expense • "Net Leverage Ratio" is calculated as net debt (total debt less cash) divided by Adjusted EBITDA over the prior twelve months.

16Copyright © Booz Allen Hamilton Inc. 2025 www.boozallen.com Booz Allen Hamilton Restricted Financial Results – Key Drivers FINANCIAL INFORMATION First Quarter Fiscal 2026 – Below is a summary of the key factors driving results for the fiscal 2026 first quarter ended June 30, 2025 as compared to the prior year period: • Revenue decreased 0.6% to $2.9 billion, primarily driven by lower billable expenses. • EBITDA increased to $297 million from $296 million. These changes were primarily due to ongoing cost management efforts, partially offset by the decrease in gross revenue. • Net income increased to $271 million from $165 million, primarily driven by a favorable agreement the Company reached with the Internal Revenue Service in the first quarter on prior years strategic tax planning initiatives, resulting in a one-time income tax benefit of $106 million. • Diluted EPS increased to $2.16 from $1.27, driven by the same factors benefiting Net Income growth, in addition to a reduction in share count. • Net cash provided by operating activities was $119 million for the quarter ended June 30, 2025, as compared to $52 million in the prior year. The change in operating cash was primarily driven by strong collection performance, as well as lower disbursements for compensation.
