Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries that are majority-owned or otherwise controlled by the Company, and have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) and should be read in conjunction with the information contained in the Company's Annual Report on Form 10-K for the year ended March 31, 2025. The interim period unaudited condensed consolidated financial statements are presented as described below. Certain information and disclosures normally required for annual financial statements have been condensed or omitted pursuant to U.S. GAAP and SEC rules and regulations. In the opinion of management, all adjustments considered necessary for fair presentation of the results of the interim periods presented have been included. The Company’s fiscal year ends on March 31 and, unless otherwise noted, references to fiscal year or fiscal are for fiscal years ended March 31. The results of operations for the three and nine months ended December 31, 2025 are not necessarily indicative of results to be expected for the full fiscal year. Certain amounts reported in the Company's prior fiscal year condensed consolidated financial statements have been reclassified to conform to the current year presentation, including the reclassification of interest income for fiscal 2025 from “Other income (expense)” into “Interest expense, net” on the condensed consolidated statement of operations. There are no changes to the Company’s financial position or results of operations as a result of this reclassification. Investments As of December 31, 2025 and March 31, 2025, respectively, the total of equity and other investments related to unconsolidated entities included in other long-term assets of the Company’s condensed consolidated balance sheet were $113 million and $90 million. Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, as well as the disclosure of contingent assets and liabilities at the date of the financial statements or during the relevant reporting periods (as applicable). The Company bases its estimates on historical and forward-looking assumptions that it believes are reasonable and appropriate. Actual results may differ materially from those estimates. Estimates are used for, but not limited to, revenue recognition including the profitability of long-term contracts and cost accruals, the provision for claimed costs, fair value measurements, the valuation and expected lives of acquired intangible assets, incentive compensation, income taxes including reserves for uncertain tax positions, postretirement obligations and contingencies. See Note 2, “Summary of Significant Accounting Policies” to the Company’s consolidated financial statements included in the Annual Report on Form 10-K for the year ended March 31, 2025 for further details on significant estimates and assumptions used. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the Financial Accounting Standards Board (the “FASB”) issued ASU 2023-09, Improvements to Income Tax Disclosures. The standard includes amendments that enhance annual income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The Company is required to adopt this standard in its Fiscal 2026 Form 10-K and determined this standard does not have a material impact on its consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, which is intended to enhance transparency into the nature and function of certain expenses as specified by the ASU. The guidance does not change the expense captions an entity presents on the face of the income statement; rather, it requires public business entities to provide disaggregated disclosures of certain expense captions in the notes to the financial statements. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, and can be applied retrospectively or prospectively. The Company is currently assessing the impact of this update; however, its adoption will affect only the Company’s disclosures, with no impacts to its results of operations or financial condition. In September 2025, the FASB issued ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software, to modernize the accounting for and disclosure of internal-use software costs. The guidance removes all references to project stages, defines the threshold to begin capitalizing costs, and clarifies the disclosure requirements of capitalized software costs. The ASU is effective for annual periods beginning after December 15, 2027, and interim periods within those fiscal years, and can be applied retrospectively, prospectively, or on a modified transition approach. Early adoption is permitted. The Company is currently assessing the impact of this update.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Government Contracting Matters - Provision for Claimed Costs U.S. government contracts and subcontracts are subject to extensive legal and regulatory requirements. From time to time and in the ordinary course of business, agencies of the U.S. government, including the Defense Contract Audit Agency (“DCAA”), audit the Company’s claimed costs and conduct inquiries and investigations of our business practices with respect to government contracts to determine whether the Company's operations are conducted in accordance with these requirements and the terms of the relevant contracts. As of December 31, 2025 and March 31, 2025, the Company had recorded liabilities of approximately $247 million and $245 million, respectively, for estimated adjustments to claimed costs based on its historical DCAA audit results, including the final resolution of such audits with DCMA, for claimed costs incurred subsequent to fiscal 2011. Investment Commitments The Company has committed to invest up to $400 million as a limited partner in a venture capital fund that focuses on late-stage venture capital investments (the “Fund”). The commitment is subject to capital calls to be funded over the Fund’s 10-year term, which may be extended in accordance with the Fund’s governing documents. The Company expects to fund at least $76 million in the fourth quarter, and that future capital calls will be concentrated in the earlier years of the Fund's operation as the Fund executes on its expected investment strategy. The Company accounts for its interest in the Fund under the equity method and the balance will be recorded in other long-term assets on the consolidated balance sheets. Leases Not Yet Commenced On November 12, 2025, the Company entered into two 15-year lease agreements for corporate office space in Reston, Virginia that have not yet commenced as of December 31, 2025. The Company plans to relocate its headquarters to the office space in the fall of 2027, dependent upon the timing of the completion of various tenant improvements. Under these lease agreements, which were entered into by Booz Allen Hamilton and are guaranteed by the Company, the estimated total undiscounted base lease payments are $222 million and the agreements provide for up to $57 million in tenant improvement allowances. Litigation Our performance under U.S. government contracts and compliance with the terms of those contracts and applicable laws and regulations are subject to continuous audit, review, and investigation by the U.S. government, which may include such investigative techniques as subpoenas or civil investigative demands. Given the nature of our business, these audits, reviews, and investigations may focus, among other areas, on various aspects of procurement integrity, labor time reporting, sensitive and/or classified information access and control, executive compensation, and post-government employment restrictions. We are not always aware of our status in such matters, but we are currently aware of certain pending audits and investigations involving labor time reporting, procurement integrity, and classified information access. In addition, from time to time, we are also involved in legal proceedings and investigations arising in the ordinary course of business, including those relating to employment matters, relationships with customers and contractors, intellectual property disputes, and other business matters. These legal proceedings seek various remedies, including claims for monetary damages in varying amounts, none of which are considered material, or are unspecified as to amount. Although the outcome of any such matter is inherently uncertain and may be materially adverse, based on current information, we do not expect any of the currently ongoing audits, reviews, investigations, or litigation to have a material adverse effect on our financial condition and results of operations.

Supplemental Condensed Consolidated Financial Information

Severance and Related Charges

The Company incurs costs related to employee severance and related charges including stock-based compensation, employee benefits and payroll taxes related to employees terminated pursuant to cost management initiatives. The Company records these costs when it is probable that employees will be entitled to termination benefits and the amounts can be reasonably estimated.

The Company’s cost management initiative and restructuring of the Civil business in the first quarter of fiscal 2026 resulted in $36 million of severance and related expenses. In the third quarter of fiscal 2026, the Company began actions to reduce costs as a result of the slowed procurement and funding environment. For the three months ended December 31, 2025, the Company recorded severance and related charges of $25 million related to this initiative. Severance and related charges included in the condensed consolidated statements of operations for the three and nine months ended December 31, 2025, are summarized below:

Divestiture

On November 30, 2025, the Company completed a transaction for the sale of a group of contracts, as well as the assets and liabilities associated with those contracts and the workforce that provides services under those contracts. As a result of this transaction, the Company recognized a pre-tax gain of $7 million which is reflected in other income (expense), on the condensed consolidated statement of operations. The consideration for the sale is subject to customary working capital adjustments and contingent consideration, which may impact the amount of the gain ultimately recognized.

Income Taxes	9 Months Ended
Income Taxes	Dec. 31, 2025
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective income tax rates were (7.0)% and 24.7% for the three months ended December 31, 2025 and 2024, respectively, and (1.6)% and 24.0% for the nine months ended December 31, 2025 and December 31, 2024, respectively. Our effective tax rates for these periods differ from the federal statutory rate of 21.0% primarily due to the inclusion of state and foreign income taxes and permanent rate differences, which are predominantly related to certain executive compensation and the accrual of reserves for uncertain tax positions, offset by research and development tax credits, excess tax benefits for employee share-based compensation, and the Foreign Derived Intangible Income deduction. During the three months ended December 31, 2025, the Company recognized a $57 million tax benefit, in conjunction with the filing of the fiscal 2025 tax return, driven primarily by a change in estimate resulting in an increase in the research and development tax credit and the Foreign Derived Intangible Income deduction. As of December 31, 2025 and March 31, 2025, the Company recorded $78 million and $142 million, respectively, of reserves for uncertain tax positions (“UTPs”) primarily related to research and development tax credits. The UTP reduction during the nine months ended December 31, 2025 is primarily related to an $86 million adjustment from the completion of Internal Revenue Service (the “IRS”) examination procedures of the Company's amended federal income tax returns through fiscal year 2021 recorded in the first quarter. The Company also accrued $23 million of interest (net of tax effect) on the related long-term receivable for the refund requested in the amended returns. Due to the magnitude of the refund requested in the amended returns, the case will be referred to the Joint Committee on Taxation (the “JCT”) for further evaluation, as required by law for tax refunds or reductions exceeding $5 million. While the JCT has not yet reviewed this case, management does not anticipate that the resolution of this review will have a material adverse effect on the Company's financial position or results of operations. As of December 31, 2025 and March 31, 2025, the Company recorded long-term income tax receivables of $176 million, including interest, and $152 million, respectively, which represents the amended U.S. federal return refund claims related to the audits referenced above and remains classified as other long-term assets on the condensed consolidated balance sheet as the case is subject to JCT review. On July 4, 2025, the One Big Beautiful Bill Act (“OBBB”) was enacted in the U.S. The OBBB includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, restoration of favorable tax treatment for certain business provisions including the expensing of domestic research and development expenditures, and modifications to the international tax framework. The Company has incorporated the impact of the new legislation into its year-to-date effective tax rate and continues to assess the impact on the consolidated financial statements.

As of December 31, 2025 and March 31, 2025, the Company had $10.5 billion and $9.5 billion of remaining performance obligations, respectively. We expect to recognize approximately 65% of the remaining performance obligations at December 31, 2025 as revenue over the next 12 months, and approximately 70% over the next 24 months. The remainder is expected to be recognized thereafter.

Contract Balances

The following table summarizes the contract assets and liabilities, and accounts receivable, net of allowance recognized on the Company’s condensed consolidated balance sheets:


	December 31, 2025		March 31, 2025
Current assets
Accounts receivable–billed	$	613	$	781
Accounts receivable–unbilled (contract assets)	1,436		1,491
Allowance for credit losses	(1)		(1)
Accounts receivable, net	2,048		2,271
Other long-term assets
Accounts receivable–unbilled (contract assets)	59		58
Total accounts receivable, net	$	2,107	$	2,329
Other current liabilities
Advance payments, billings in excess of costs incurred and deferred revenue (contract liabilities)	$	20	$	18

Changes in contract assets and contract liabilities are primarily due to the timing difference between the Company’s performance of services and payments from customers. For both the three months ended December 31, 2025 and 2024, we recognized revenue of $1 million, and for the nine months ended December 31, 2025 and 2024, we recognized revenue of $13 million and $11 million, respectively, related to our contract liabilities on April 1, 2025 and 2024, respectively.

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Recurring Fair Value Measurements

The financial instruments measured at fair value in the accompanying condensed consolidated balance sheets consisted of the following at the periods presented below:


	December 31, 2025						March 31, 2025
	Level 1		Level 2		Total			Level 1		Level 2		Total
Assets:

Long-term deferred compensation plan liability	43		—		43			35		—		35
Total Liabilities	$	43	$	3	$	46		$	35	$	3	$	38

The Company did not have any Level 3 assets or liabilities as of December 31, 2025 or March 31, 2025.

Derivatives

The Company utilizes interest rate derivative financial instruments, which were designated as cash flow hedges, to manage its exposure to interest rate risk related to its variable rate debt and reducing volatility of interest expense as the variable-to-fixed interest rate swaps effectively convert a portion of the variable rate debt into fixed interest rate debt. The Company’s outstanding interest rate swaps have a total notional amount of $350 million as of December 31, 2025 and mature from June 30, 2026 to June 30, 2027.

The Company’s interest rate swaps are considered over-the-counter derivatives which are recorded in the condensed consolidated balance sheet on a gross basis at estimated fair value. Fair value is estimated based on the present value of future cash flows using a model-derived valuation that uses Level 2 observable inputs such as interest rate yield curves. The changes in the fair value of interest rate swaps designated as cash flow hedges are recorded in AOCI, net of taxes, and are subsequently reclassified into interest expense, net in the period that the hedged forecasted interest payments are made on the Company's variable-rate debt. Over the next 12 months, the Company estimates that approximately $2 million will be reclassified as an increase to interest expense. Cash flows associated with periodic settlements of interest rate swaps are classified as operating activities in the condensed consolidated statement of cash flows.

Deferred Compensation Plans

Investments in this category consist primarily of mutual funds whose fair values are determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. These assets are recorded in other long-term assets and represent investments held in a consolidated trust to fund the Company's non-qualified deferred compensation plan, which is recorded in other long-term liabilities on our condensed consolidated balance sheets.

Cash and Cash Equivalents

As of December 31, 2025 and March 31, 2025, the Company's cash and cash equivalents presented on the accompanying condensed consolidated balance sheets include the money market funds disclosed in the table above. As of both December 31, 2025 and March 31, 2025, the fair value of the Company’s cash and cash equivalents approximated its carrying value.

Long-term Debt

The Company's long-term debt is carried at amortized cost and fair value is disclosed on a quarterly basis. The estimated fair values of debt are determined using quoted prices or other market information obtained from recent trading activity of the debt in markets that are not active (Level 2 inputs). The fair value is corroborated by prices derived from the interest rate spreads of recently completed leveraged loan transactions of a similar credit profile, industry, and terms to that of the Company. The fair value of the Senior Notes are determined using quoted prices or other market information obtained from recent trading activity in the high-yield bond market (Level 2 inputs). The estimated fair value of long-term debt as of December 31, 2025 and March 31, 2025 was $3,970 million and $3,954 million, respectively.

Nonrecurring Fair Value Measurements

As of December 31, 2025 and March 31, 2025, the total of our investments that are accounted for at fair value on a non-recurring basis under the measurement alternative were $107 million and $85 million, respectively. While these assets are not measured at fair value on an ongoing basis, they are subject to fair value adjustments in certain circumstances (e.g., observable price changes or impairment).

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Basis of Presentation (Policies)	9 Months Ended
Basis of Presentation (Policies)	Dec. 31, 2025
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries that are majority-owned or otherwise controlled by the Company, and have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) and should be read in conjunction with the information contained in the Company's Annual Report on Form 10-K for the year ended March 31, 2025. The interim period unaudited condensed consolidated financial statements are presented as described below. Certain information and disclosures normally required for annual financial statements have been condensed or omitted pursuant to U.S. GAAP and SEC rules and regulations. In the opinion of management, all adjustments considered necessary for fair presentation of the results of the interim periods presented have been included.
Reclassification	Certain amounts reported in the Company's prior fiscal year condensed consolidated financial statements have been reclassified to conform to the current year presentation
Investments	Investments As of December 31, 2025 and March 31, 2025, respectively, the total of equity and other investments related to unconsolidated entities included in other long-term assets of the Company’s condensed consolidated balance sheet were $113 million and $90 million.
Accounting Estimates	Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, as well as the disclosure of contingent assets and liabilities at the date of the financial statements or during the relevant reporting periods (as applicable). The Company bases its estimates on historical and forward-looking assumptions that it believes are reasonable and appropriate. Actual results may differ materially from those estimates. Estimates are used for, but not limited to, revenue recognition including the profitability of long-term contracts and cost accruals, the provision for claimed costs, fair value measurements, the valuation and expected lives of acquired intangible assets, incentive compensation, income taxes including reserves for uncertain tax positions, postretirement obligations and contingencies. See Note 2, “Summary of Significant Accounting Policies” to the Company’s consolidated financial statements included in the Annual Report on Form 10-K for the year ended March 31, 2025 for further details on significant estimates and assumptions used.
Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the Financial Accounting Standards Board (the “FASB”) issued ASU 2023-09, Improvements to Income Tax Disclosures. The standard includes amendments that enhance annual income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The Company is required to adopt this standard in its Fiscal 2026 Form 10-K and determined this standard does not have a material impact on its consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, which is intended to enhance transparency into the nature and function of certain expenses as specified by the ASU. The guidance does not change the expense captions an entity presents on the face of the income statement; rather, it requires public business entities to provide disaggregated disclosures of certain expense captions in the notes to the financial statements. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, and can be applied retrospectively or prospectively. The Company is currently assessing the impact of this update; however, its adoption will affect only the Company’s disclosures, with no impacts to its results of operations or financial condition. In September 2025, the FASB issued ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software, to modernize the accounting for and disclosure of internal-use software costs. The guidance removes all references to project stages, defines the threshold to begin capitalizing costs, and clarifies the disclosure requirements of capitalized software costs. The ASU is effective for annual periods beginning after December 15, 2027, and interim periods within those fiscal years, and can be applied retrospectively, prospectively, or on a modified transition approach. Early adoption is permitted. The Company is currently assessing the impact of this update.
Revenue	We disaggregate our revenue from contracts with customers by contract type and by customer type, as well as by whether the Company acts as prime contractor or subcontractor, as we believe these categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Remaining performance obligations represent the transaction price of exercised contracts for which work has not yet been performed, irrespective of whether funding has or has not been authorized and appropriated as of the date of exercise. Remaining performance obligations exclude negotiated but unexercised options, the unfunded value of expired contracts, and certain variable consideration that was determined to be constrained.
