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, and significant acquisition amortization. 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 attributable to common stockholders before income taxes, net interest and other expense and depreciation and amortization and before certain other items, including acquisition and divestiture costs, restructuring costs, financing transaction costs, and supplemental employee benefits due to COVID-19. “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 attributable to common stockholders before:(i) acquisition and divestiture costs, (ii) financing transaction costs, (iii) significant acquisition amortization, and (iv) amortization and 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 Adjusted Net Income 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. "Net Leverage Ratio" is calculated as net debt (total debt less cash) divided by the last twelve months Adjusted EBITDA. 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. Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Last 12 months Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow, Free Cash Flow Conversion, and Net Leverage Ratio 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 attributable to common stockholders to Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Last 12 months Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted Earnings per Share, net cash used in operating activities to Free Cash Flow and Free Cash Flow Conversion, and net debt to Net Leverage Ratio, (ii) use Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Last 12 months Adjusted EBITDA, 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, Free Cash Flow Conversion, and Net Leverage Ratio, 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. 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, Last 12 months Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow, Free Cash Flow Conversion, and Net Leverage Ratio 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 3

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.
