2 Reconciliations omitted in reliance on Item 10(e)(1)(i)(B) of Regulation S-K. See "Non-GAAP Financial Information."

3 Fiscal 2027 Guidance assumes an effective tax rate of 16-19% and average diluted shares outstanding of 118-120 million.

4 Fiscal 2027 Guidance assumes capital expenditures of approximately $200 million.

Booz Allen utilizes and discusses in this release Revenue, Excluding Billable Expenses, EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow. While we believe that these non-GAAP financial measures may be useful in evaluating our financial information, they should be considered as supplemental in nature and not as a substitute for financial information prepared in accordance with GAAP. Reconciliations, definitions, and how we believe these measures are useful to management and investors are provided below. Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow 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.

"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 tax expense, interest expense, net and other income (expense), and depreciation and amortization.

"Adjusted EBITDA" represents net income before income tax expense (benefit), interest expense, net and other income (expense), and depreciation and amortization and before certain other items, including certain other corporate expenses. "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 certain other corporate expenses and acquisition amortization, 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, 2026.

"Free Cash Flow" represents the net cash generated from operating activities less the impact of purchases of property, equipment and software. 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.These non-GAAP measurements may vary from and may not be comparable to similarly titled measures by other companies in Booz Allen's industry.

"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.

Revenue, Excluding Billable Expenses, EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow, 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, net income to Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted Net Income, and Adjusted Diluted Earnings Per Share, net cash provided by operating activities to Free Cash Flow, and net debt to Net Leverage Ratio, (ii) use Revenue, Excluding Billable Expenses, EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted Net Income, and Adjusted Diluted EPS in addition to, and not as an alternative to, revenue, net income or diluted EPS as measures of operating results, each as defined under GAAP, (iii) use Free Cash Flow and Net Leverage Ratio, 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, 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 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.

With respect to our expectations under "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 2026. Projecting future stock price, equity grants, and the 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. Accordingly, Booz Allen is relying on the exception provided by Item 10(e)(1)(i)(B) of Regulation S-K to exclude the reconciliation.

In addition, our expectations for Adjusted EBITDA and Adjusted EBITDA Margin on Revenue for fiscal 2026 are presented under "Outlook" above and management may discuss its expectation for Adjusted EBITDA and Adjusted EBITDA Margin on Revenue for fiscal 2026 from time to time. A reconciliation of Adjusted EBITDA and 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 quantification 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. Accordingly, Booz Allen is relying on the exception provided by Item 10(e)(1)(i)(B) of Regulation S-K to exclude the reconciliation.

Certain statements contained in this press release 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 the risks and factors described in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on May 22, 2026 and in our other filings with the SEC. In light of these risks, uncertainties, and other factors, the forward-looking statements might not prove to be accurate and you should not place undue reliance upon them. All forward-looking statements speak only as of the date made and we undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events, or otherwise.
