NON-GAAP FINANCIAL INFORMATION “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 that are not indicative of the level of productivity of its client staff headcount and its overall direct labor, which management believes provides useful information to its investors about its core operations. “Adjusted Operating Income” represents operating income before acquisition and divestiture costs, financing transaction costs, supplemental employee benefits due to COVID-19, significant acquisition amortization, and restructuring costs. Booz Allen prepares Adjusted Operating Income 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 EBITDA” represents net income before income taxes, net interest and other expense and depreciation and amortization and before certain other items, including acquisition and divestiture costs, financing transaction costs, supplemental employee benefits due to COVID-19, and restructuring costs. “Adjusted EBITDA Margin on Revenue” is calculated as Adjusted EBITDA divided by revenue. “Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses” is calculated as Adjusted EBITDA divided by Revenue, Excluding Billable Expenses. Booz Allen prepares Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, and Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses 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) acquisition and divestiture costs, (ii) financing transaction costs, (iii) supplemental employee benefits due to COVID-19, (iv) significant acquisition amortization, (v) restructuring costs, (vi) gain associated with equity method investment activities, (vii) research and development tax credits, (viii) release of income tax reserves, (ix) remeasurement of deferred tax assets/ liabilities, (x) loss on debt extinguishment, and (xi) 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. Booz Allen views net income excluding the impact of the re-measurement of the Company's deferred tax assets and liabilities as an important indicator of performance consistent with the manner in which management measures and forecasts the Company's performance and the way in which management is incentivized to perform. “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, 2022. "Free Cash Flow" represents the net cash generated from operating activities less the impact of purchases of property, equipment and software. "Free Cash Flow Conversion" is calculated as Free Cash Flow divided by Adjusted Net Income. Booz Allen utilizes and discusses in this release Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, and Adjusted Diluted EPS because management uses these measures for business planning purposes, including managing its business against internal projected results of operations and measuring its performance. Management views Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, and Adjusted Diluted EPS as measures of the core operating business, which exclude the impact of the items detailed in the supplemental exhibits, as these items are generally not operational in nature. These non-GAAP measures also provide another basis for comparing period to period results by excluding potential differences caused by non-operational and unusual or non-recurring items. Management also utilizes 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 its client staff headcount and its overall direct labor, which management believes provides useful information to its investors about its core operations. Booz Allen also utilizes and discusses Free Cash Flow in this release because management uses this measure for business planning purposes, measuring the cash generating ability of the operating business and measuring liquidity generally. Booz Allen presents these supplemental 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 non-GAAP measurements may vary from and may not be comparable to similarly titled measures by other companies in Booz Allen’s industry. 3

Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow 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, operating income to Adjusted Operating Income, net income to Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, and Adjusted Diluted Earnings per Share, and net cash provided by operating activities to Free Cash Flow, (ii) use Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, 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, each as defined under GAAP, 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. Exhibit 4 includes a reconciliation of Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow to the most directly comparable financial measure calculated and presented in accordance with GAAP. With respect to our expectations under “Financial Outlook” above, a 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 2023. 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. In addition, our expectations for Adjusted EBITDA Margin on Revenue for fiscal 2023 is presented under "Financial Outlook" above and management may discuss its expectation for Adjusted EBITDA Margin on Revenue for fiscal 2025 from time to time. A reconciliation of Adjusted EBITDA Margin on Revenue guidance to the closest corresponding GAAP measure is 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. Consequently, any attempt to disclose such reconciliation would imply a degree of precision that could be confusing or misleading to investors.

3 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, 2022, 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 Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow, and Free Cash Flow Conversion, 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, operating income to Adjusted Operating Income, net income to Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income and Adjusted Diluted EPS, and net cash provided by operating activities to Free Cash Flow and Free Cash Flow Conversion, 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 on Revenue, Adjusted EBITDA Margin on Revenue Excluding Billable Expenses, 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, each as defined under GAAP, and (iii) use Free Cash Flow and Free Cash Flow Conversion, 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 Appendix includes a reconciliation of Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow, and Free Cash Flow Conversion 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” and "FY23 ADEPS Walk," reconciliation of Adjusted Diluted EPS guidance, Adjusted EBITDA, and Adjusted EBITDA Margin on Revenue 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 and Adjusted EBITDA Margin on Revenue, during the course of fiscal 2023. 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 2023 and 2025 and of Adjusted EBITDA guidance through fiscal 2025 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.

12 APPENDIX

13 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 client 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 acquisition and divestiture costs, financing transaction costs, supplemental employee benefits due to COVID-19, significant acquisition amortization, and restructuring costs. 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 acquisition and divestiture costs, financing transaction costs, supplemental employee benefits due to COVID-19, and restructuring costs. “Adjusted EBITDA Margin on Revenue” is calculated as Adjusted EBITDA divided by revenue. Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses is calculated as Adjusted EBITDA divided by Revenue, Excluding Billable Expenses. We prepare Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, and Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses 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) acquisition and divestiture costs, (ii) financing transaction costs, (iii) supplemental employee benefits due to COVID-19, (iv) significant acquisition amortization, (v) restructuring costs, (vi) gain associated with equity method investment activities, (vii) research and development tax credits, (viii) release of income tax reserves, (ix) remeasurement of deferred tax assets/ liabilities, (x) loss on debt extinguishment, and (xi) 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. 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. We view net income excluding the impact of the re-measurement of the Company's deferred tax assets and liabilities as an important indicator of performance consistent with the manner in which management measures and forecasts the Company's performance and the way in which management is incentivized to perform. • "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 our consolidated financial statements in our Form 10-K for the fiscal year ended March 31, 2022. • "Free Cash Flow" represents the net cash generated from operating activities less the impact of purchases of property, equipment and software. "Free Cash Flow Conversion" is calculated as Free Cash Flow divided by Adjusted Net Income.

15 FINANCIAL RESULTS – KEY DRIVERS Fourth Quarter Fiscal 2022 – Below is a summary of the key factors driving results for the fiscal 2022 fourth quarter ended March 31, 2022 as compared to the prior year period: • Revenue increased 13.1% to $2.2 billion and Revenue, Excluding Billable Expenses increased 14.3% to $1.6 billion. Revenue growth was primarily driven by the impact from fiscal 2022 acquisitions, continued client demand, and higher staff utilization in the current period. • Operating income decreased 13.3% to $148.3 million and Adjusted Operating Income increased 2.7% to $176.1 million. The decrease in operating income was impacted by $11.7 million in acquisition costs as well as increases in depreciation and amortization primarily due to the recent acquisitions. These decreases were partially offset by profitable contract level performance and mix which includes inorganic contributions, and prudent cost management. The increase in Adjusted Operating Income was primarily driven by the same factors driving revenue growth. • Net income decreased 54.4% to $90.8 million and Adjusted Net Income decreased 6.6% to $115.1 million. These changes were primarily driven by the same factors as operating income and Adjusted Operating Income. Net income and Adjusted Net Income were also affected by higher interest expense and a higher effective tax rate due to strategic tax planning initiatives in the prior year. • EBITDA decreased 1.7% to $189.2 million and Adjusted EBITDA increased 6.3% to $205.0 million. These changes were due to the same factors as operating income and Adjusted Operating Income, respectively. • Diluted EPS decreased to $0.68 from $1.43 and Adjusted Diluted EPS decreased to $0.86 from $0.89. The changes were primarily driven by the same factors as Net Income and Adjusted Net Income, respectively, partially offset by a lower share count in the fourth quarter of fiscal 2022.

16 FINANCIAL RESULTS – KEY DRIVERS Fiscal year ended March 31, 2022 – Below is a summary of the key factors driving results for the fiscal year 2022 ended March 31, 2022 as compared to the prior year: • Revenue increased 6.4% to $8.4 billion and Revenue, Excluding Billable Expenses increased 6.4% to $5.9 billion. Revenue growth was primarily driven by the impact of acquisitions during fiscal 2022 and strong demand, partially offset by reduced staff utilization. • Operating income decreased 9.2% to $685.2 million and Adjusted Operating Income increased 9.5% to $827.5 million. The decrease in operating income was impacted by $97.5 million in acquisition and divestiture costs as well as increases in depreciation and amortization primarily due to the recent acquisitions. These decreases were partially offset by profitable contract level performance and mix which includes inorganic contributions, and prudent cost management. The increase in Adjusted Operating Income was primarily driven by the same factors driving revenue growth and prudent cost management. In addition, fiscal 2021 operating income was impacted by approximately $24.0 million by the inability to recognize revenue on, or bill for, fee on certain contracts involving a ready workforce. • Net income decreased 23.4% to $466.6 million and Adjusted Net Income increased 4.9% to $568.0 million. These changes were primarily driven by the same factors as operating income and Adjusted Operating Income. Net income and Adjusted Net Income were also affected by higher interest expense and a higher effective tax rate due to strategic tax planning initiatives in the prior year. In addition, fiscal 2022 includes $12.8 million in gains from equity method investment activities as compared to fiscal 2021 which includes a $13.2 million loss on debt extinguishment. • EBITDA decreased 0.9% to $830.9 million and Adjusted EBITDA increased 11.3% to $934.9 million. These changes were due to the same factors as operating income and Adjusted Operating Income. • Diluted EPS decreased to $3.44 from $4.37 and Adjusted Diluted EPS increased to $4.21 from $3.90. The changes were primarily driven by the same factors as Net Income and Adjusted Net Income, respectively, partially offset by a lower share count in fiscal 2022. • As of March 31, 2022, total backlog was $29.2 billion, an increase of 21.7% as compared to the prior year. Funded backlog was $3.7 billion, an increase of 5.7% as compared to the prior year. • Net cash provided by operating activities was $736.5 million for the full fiscal year ended March 31, 2022, as compared to $718.7 million in the prior year. The increase in operating cash flows was primarily driven by strong working capital management, partially offset by approximately $97.5 million of acquisition costs incurred and paid during fiscal 2022, primarily associated with our acquisitions of Liberty and Tracepoint. Free Cash Flow was $656.6 million for the fiscal year ended March 31, 2022, as compared to $631.5 million in the prior year. Free Cash Flow was affected by the same factors affecting cash provided by operating activities, as well as a decrease in capital expenditures driven by lower spend related to the implementation of our new financial management system on April 1, 2021 as compared to the prior year, as well as lower facilities expenses reflecting the investment in technology and tools needed to support the virtual work environment.
