Accounting Policies [Abstract]  
Summary of Significant Accounting Policies Summary of Significant Accounting Policies
Use of Estimates
The preparation of financial statements in conformity with generally accepted accounting principles in the U.S. (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reported periods. The most significant of these estimates and assumptions relate to estimating contract revenues and costs, measuring progress against the Company’s performance obligations, assessing the fair value of acquired assets and liabilities accounted for through business acquisitions, valuing and determining the amortization periods for long-lived intangible assets, assessing the recoverability of long-lived assets, reserves for accounts receivable, and reserves for contract related matters. Management evaluates its estimates on an ongoing basis using the most current and available information. However, actual results may differ significantly from estimates. Changes in estimates are recorded in the period in which they become known.
Business Combinations
The Company records all tangible and intangible assets acquired and liabilities assumed in a business combination at fair value as of the acquisition date, with any excess purchase consideration recorded as goodwill. For contingent purchase consideration, a liability is recognized at fair value as of the acquisition date with subsequent fair value adjustments recorded in operations. The Company uses various valuation methods, including the relief-from-royalty method of the income approach, to determine the fair value of acquired assets and liabilities assumed. The use of these methods requires management to make significant judgments about expected future cash flows, weighted average cost of capital, discount rates, royalty rates, and expected long-term growth rates. During the measurement period, not to exceed one year from the acquisition date, the Company may adjust provisional amounts recorded to reflect new information subsequently obtained regarding facts and circumstances that existed as of the acquisition date.
Acquisition and Integration Costs
Costs associated with legal, financial, and other professional advisors related to acquisitions, whether successful or unsuccessful, as well as applicable integration costs are expensed as incurred.
Revenue Recognition
The Company generates almost all of our revenues from three different types of contractual arrangements with the U.S. government: cost-plus-fee, fixed-price, and time-and-materials contracts. Our contracts with the U.S. government are generally subject to the Federal Acquisition Regulation (FAR) and are competitively priced based on estimated costs of providing the contractual goods or services.
We account for a contract when the parties have approved the contract and are committed to perform on it, the rights of each party and the payment terms are identified, the contract has commercial substance, and collectability is probable. At contract inception, the Company determines whether the goods or services to be provided are to be accounted for as a single performance obligation or as multiple performance obligations. This evaluation requires professional judgment as it may affect the timing and pattern of revenue recognition. If multiple performance obligations are identified, we generally use the cost plus a margin approach to determine the relative standalone selling price of each performance obligation.
When determining the total transaction price, the Company identifies both fixed and variable considerations within the contract. Variable consideration includes any amount within the transaction price that is not fixed, such as: award or incentive fees; performance penalties; unfunded contract value; or other similar items. For our contracts with award or incentive fees, the Company estimates the total amount of award or incentive fee expected to be recognized into revenues. Throughout the performance period, the Company recognizes as revenue a constrained amount of variable consideration only to the extent that it is probable that a significant reversal of the cumulative amount recognized to date will not be required in a subsequent period. The Company’s estimate of variable consideration is periodically adjusted based on significant changes in relevant facts and circumstances. In the period in which the Company can calculate the final amount of award or incentive fee earned based on the receipt of the customers' final performance score or the determination that more objective, contractually-defined criteria have been fully satisfied, the Company will adjust its cumulative revenue recognized to date on the contract.
The Company generally recognizes revenues over time throughout the performance period as the customer simultaneously receives and consumes the benefits provided on services-type revenue arrangements. This continuous transfer of control for U.S. government contracts is supported by the unilateral right of the customer to terminate the contract for a variety of reasons without having to provide justification for its decision. For services-type revenue arrangements in which there are a repetitive amount of services that are substantially the same from one month to the next, the Company applies the series guidance. The Company uses a variety of input and output methods that approximate the progress towards complete satisfaction of the performance obligation, including costs incurred, labor hours expended, and time-elapsed measures for fixed-price stand ready obligations. For certain contracts, primarily cost-plus and time-and-materials services-type revenue arrangements, the Company applies the right-to-invoice practical expedient in which revenues are recognized in direct proportion to the Company’s present right to consideration for progress towards the complete satisfaction of the performance obligation.
When a performance obligation has a significant degree of interrelation or interdependence between one month’s activities and the next, when there is an award or incentive fee, or when there is a significant degree of customization or modification, the Company generally records revenue using a percentage of completion method. For these revenue arrangements, substantially all revenues are recognized over time using a cost-to-cost input method based on the ratio of costs incurred to date to total estimated costs at completion. When estimates of total costs to be incurred on a contract exceed total revenue, a provision for the entire loss on the contract is recorded in the period in which the loss is determined.
Contract modifications are reviewed to determine whether they should be accounted for as part of the original performance obligation or as a separate contract. Contract modifications that add distinct goods or services and increase the contract value by an amount that reflects the standalone selling price are accounted for as separate contracts. When the contract modification includes goods or services that are not distinct from those already provided, the Company records a cumulative adjustment to revenues based on a remeasurement of progress towards the complete satisfaction of the not yet fully delivered performance obligation.
Based on the critical nature of our contractual performance obligations, the Company may proceed with work based on customer direction prior to the completion and signing of formal contract documents. The Company has a formal review process for approving any such work that considers previous experiences with the customer, communications with the customer regarding funding status, and the Company’s knowledge of available funding for the contract or program.
Costs of Revenues
Costs of revenues includes all direct contract costs such as labor, materials, subcontractor costs, and indirect costs that are allowable and allocable to contracts under federal procurement standards. Costs of revenues also includes expenses that are unallowable under applicable procurement standards and are not allocable to contracts for billing purposes. Such unallowable expenses do not directly generate revenues but are necessary for business operations.
Changes in Estimates on Contracts
The Company recognizes revenues on many of its fixed-price, award fee, and incentive fee arrangements over time primarily using a cost-to-cost input method based on the ratio of costs incurred to date to total estimated costs at completion. The process requires the Company to use professional judgment when assessing risks, estimating contract revenues and costs, estimating variable consideration, and making assumptions for schedule and technical issues. The Company periodically reassesses its assumptions and updates its estimates as needed.
Contract Balances
Contract assets include unbilled receivables in which our right to consideration is conditional on factors other than the passage of time. Contract assets exclude billed and billable receivables.
In addition, the costs to fulfill and obtain a contract are considered for capitalization based on contract specific facts and circumstances. The incremental costs to fulfill a contract (e.g., ramp up costs at the beginning of the period of performance) may be capitalized when costs are incurred prior to satisfying a performance obligation. The incremental costs of obtaining a contract (e.g., sales commissions) are capitalized as an asset when the Company expects to recover them either directly or indirectly through the revenue arrangement’s profit margins. These capitalized costs are subsequently expensed over the revenue arrangement’s period of performance. The Company has elected to apply the practical expedient to immediately expense the costs to obtain a contract when the performance obligation will be completed within twelve months of contract inception.
Contract assets are periodically reassessed based on reasonably available information as of the balance sheet date to ensure they do not exceed their net realizable value.
Contract liabilities primarily include advance payments received from a customer in excess of revenues that may be recognized as of the balance sheet date. The advance payment is subsequently recognized into revenues as the performance obligation is satisfied.
Remaining Performance Obligations
Remaining performance obligations (RPO) represent the expected revenues to be recognized for the satisfaction of remaining performance obligations on existing contracts. This balance excludes unexercised contract option years and task orders that may be issued underneath an indefinite delivery/indefinite quantity vehicle until such task orders are awarded. The RPO balance generally increases with the execution of new contracts and converts into revenues as contractual performance obligations are satisfied. The Company continues to monitor this balance as it is subject to change from execution of new contracts, contract modifications or extensions, government deobligations, or early terminations.
Cash and Cash Equivalents
The Company considers all investments with an original maturity of three months or less on their trade date to be cash equivalents. The Company classifies investments with an original maturity of more than three months but less than twelve months on their trade date as short-term marketable securities.
Receivables
Receivables include billed and billable receivables, and unbilled receivables. Billable and unbilled receivables are recognized at estimated realizable value, substantially all of which are expected to be billed and collected generally within one year. When events or conditions indicate that amounts outstanding from customers may become uncollectible, an allowance is estimated and recorded. Upon determination that a specific receivable is uncollectible, the receivable is written off against the allowance for expected credit losses. The Company’s allowance for expected credit losses was $8.1 million and $6.1 million at June 30, 2025 and June 30, 2024, respectively.
Concentrations of Credit Risk
Financial instruments that potentially subject the Company to credit risk include accounts receivable and cash equivalents. Management believes that credit risk related to the Company’s accounts receivable is limited due to a large number of customers in differing segments and agencies of the U.S. government. Accounts receivable credit risk is also limited due to the creditworthiness of the U.S. government. Management believes the credit risk associated with the Company’s cash equivalents is limited due to the creditworthiness of the obligors of the investments underlying the cash equivalents. In addition, although the Company maintains cash balances at financial institutions that exceed federally insured limits, these balances are placed with high quality financial institutions.
Inventories
Inventories are stated at the lower of cost (average cost or first-in, first-out) or net realizable value and are included in prepaid expenses and other current assets on the consolidated balance sheets. The Company periodically assesses its current inventory balances and records a provision for damaged, deteriorated, or obsolete inventory based on historical patterns and forecasted sales.
Goodwill and Intangible Assets
Goodwill represents the excess of the fair value of consideration paid for an acquisition over the fair value of the net assets acquired as of the acquisition date. The Company evaluates goodwill for both of its reporting units for impairment annually on the first day of the fiscal fourth quarter, or whenever events or circumstances indicate that the carrying value may not be recoverable. The evaluation includes a qualitative assessment or a quantitative assessment that compares the fair value of the relevant reporting unit to its respective carrying value, including goodwill, and utilizes both income and market approaches. The analysis relies on significant judgments and assumptions about expected future cash flows, weighted average cost of capital, discount rates, expected long-term growth rates, and financial measures derived from observable market data of comparable public companies.
Intangible assets with finite lives are amortized using the method that best reflects how their economic benefits are utilized or, if a pattern of economic benefits cannot be reliably determined, on a straight-line basis over their estimated useful lives, which is generally over periods ranging from one to twenty-five years. Intangible assets with finite lives are assessed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable at the asset group level.
Property, Plant, and Equipment
Purchases of property, plant, and equipment are capitalized at cost. Depreciation of equipment and furniture has been provided over the estimated useful life of the respective assets (ranging from three to eight years) using the straight-line method. Leasehold improvements are generally amortized using the straight-line method over the remaining lease term or the useful life of the improvements, whichever is shorter. Repairs and maintenance costs are expensed as incurred.
The Company evaluates its long-lived assets for potential impairment whenever there is evidence that events or changes in circumstances indicate that the carrying value may not be recoverable and the carrying amount of the asset exceeds its estimated fair value at the asset group level.
External Software Development Costs
Costs incurred in creating software to be sold or licensed for external use are expensed as incurred until technological feasibility has been established. Technological feasibility is established upon completion of a detailed program design or, in its absence, completion of a working model. Thereafter, all such software development costs are capitalized and subsequently reported at the lower of unamortized cost or estimated net realizable value. Capitalized costs are amortized on a straight-line basis over the remaining estimated economic life of the software.
Leases
The Company enters into contractual arrangements primarily for the use of real estate facilities, IT equipment, and certain other equipment. These arrangements contain a lease when the Company controls the underlying asset and has the right to obtain substantially all of the economic benefits or outputs from the asset. All of the Company’s leases are operating leases.
The Company records a right-of-use (ROU) asset and lease liability as of the lease commencement date equal to the present value of the remaining lease payments. Most of the Company’s leases do not provide an implicit rate that can be readily determined. Therefore, the Company uses a discount rate based on its incremental borrowing rate, which is determined using its credit rating and information available as of the commencement date. The ROU asset is then adjusted for initial direct costs and certain lease incentives included in the contractual arrangement. The Company combines and accounts for lease and non-lease components as a single component for facility leases. The Company has elected the practical expedient to not recognize lease liabilities and ROU assets for short-term equipment and other non-facility leases. Operating lease arrangements may contain options to extend the lease term or for early termination. The Company accounts for these options when exercise is reasonably certain. ROU assets are evaluated for impairment in a manner consistent with the treatment of other long-lived assets.
Operating lease expense is recognized on a straight-line basis over the lease term and is recorded primarily within indirect costs and selling expenses on the consolidated statements of operations. Variable lease expenses are recorded in the period they are incurred and are excluded from the ROU asset and lease liability.
Earnings Per Share
Basic earnings per share excludes dilution and is computed by dividing income by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock but not securities that are anti-dilutive. Using the treasury stock method, diluted earnings per share includes the incremental effect of restricted stock units (RSUs) that are no longer subject to a market or performance condition. Information about the weighted average number of basic and diluted shares is presented in “Note 14 – Earnings Per Share”.
Stock-Based Compensation
We issue stock-based awards as compensation to employees and directors in the form of Restricted Stock Units (RSUs) and Performance-based Restricted Stock Units (PRSUs). These awards are accounted for as equity awards. We recognize stock-based compensation expense net of estimated forfeitures on a straight-line basis over the underlying award’s requisite service period, as measured using the award’s grant date fair value. The grant date fair value is based on the closing market price of our common stock on the grant date. For PRSUs, we assess the probability of achieving the performance conditions at each reporting period and adjust compensation expense based on the number of shares we expect to issue.
Income Taxes
Income taxes are accounted for using the asset and liability method which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities due to a change in tax rates is recognized in income in the period that includes the enactment date. Estimates of the realizability of deferred tax assets are based on the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies.
Liabilities for uncertain tax positions are recognized when it is more likely than not that a tax position will not be sustained upon examination and settlement with taxing authorities. Liabilities for uncertain tax positions are measured based upon the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. Tax penalties and interest are included in income tax expense.
Foreign Currency
The assets and liabilities of the Company’s foreign subsidiaries whose functional currency is other than the U.S. dollar are translated at the exchange rate in effect on the reporting date, and income and expenses are translated at the weighted average exchange rate during the period. The Company’s primary practice is to negotiate contracts in the same currency in which the predominant expenses are incurred, thereby mitigating the exposure to foreign currency fluctuations. The net translation gains and losses are recorded as accumulated other comprehensive income (loss) in shareholders’ equity. Foreign currency transaction gains and losses are recorded as incurred in indirect costs and selling expenses on the consolidated statements of operations.
Other Comprehensive Income (Loss)
The elements within other comprehensive income consist of foreign currency translation adjustments; the changes in the fair value of interest rate swap agreements, net of tax benefit (expense) of $6.3 million, $2.5 million and $(6.1) million for the years ended June 30, 2025, 2024 and 2023, respectively; and differences between actual amounts and estimates based on actuarial assumptions and the effect of changes in actuarial assumptions made under the Company’s post-retirement benefit plans, net of tax (see "Note 13 - Composition of Certain Financial Statement Captions").
As of June 30, 2025, 2024 and 2023, the accumulated other comprehensive loss balance included (losses) gains of: $(13.0) million, $(37.4) million, and $(37.0) million, respectively, related to foreign currency translation adjustments; $4.9 million, $23.4 million, and $30.9 million, respectively, related to the fair value of interest rate swap agreements; and $1.2 million, $1.3 million, and $1.1 million, respectively, related to unrecognized post-retirement costs.
Commitments and Contingencies
Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated.

Applied Insight delivers proven cloud migration, adoption, and transformation capabilities, coupled with intimate customer relationships across the Department of Defense (DoD) and intelligence communities. The Company preliminarily recognized fair values of the assets acquired and liabilities assumed and allocated $217.5 million to goodwill and $95.2 million to intangible assets. The intangible assets consist of customer relationships of $84.3 million and technologies of $10.9 million, with an amortization period of eight and five years, respectively. The goodwill is primarily associated with future customer relationships and an acquired assembled workforce. Of the value attributed to goodwill and intangible assets, $248.6 million is deductible for income tax purposes. The Company funded the acquisition with cash on hand and borrowings under its debt instruments.
Azure Summit Technology
On October 30, 2024, CACI acquired all of the equity interests of Azure Summit Technology, LLC (Azure Summit) for purchase consideration of $1,310.2 million, net of cash acquired, subject to adjustments for working capital and certain other items.

The estimated fair value attributed to intangible assets of $635.0 million consists of customer relationships of $270.5 million and technologies of $364.5 million. The fair value attributed to intangible assets is being amortized over 10 to 20 years for customer intangibles and 20 to 25 years for technologies. The fair value attributed to the intangible assets acquired was based on assumptions and other information compiled by management, including independent valuations that utilized established valuation techniques.
Identity E2E
On April 3, 2025, CACI Limited acquired all of the equity interests of Identity E2E Limited (Identity E2E) for purchase consideration of $58.9 million, net of cash acquired, subject to adjustments for working capital and certain other items. Identity E2E provides specialized technology services in biometrics and cloud engineering to customers within the United Kingdom (U.K.). The purchase price includes $7.3 million of contingent consideration, which represents the acquisition date fair value recognized for up to $7.8 million of potential future earnout payments based on the achievement of certain profitability targets of the acquiree during the two-year period following the acquisition date.
The Company preliminarily recognized fair values of the assets acquired and liabilities assumed and allocated $50.1 million to goodwill and $10.2 million to intangible assets. The intangible assets are related to customer relationships and with an amortization period of 10 years. At June 30, 2025, the Company had not finalized the determination of fair values allocated to assets and liabilities, including but not limited to, accounts receivables, intangible assets, and goodwill. The goodwill is primarily associated with future customer relationships and an acquired assembled workforce. None of the values attributed to goodwill and intangible assets is deductible for income tax purposes. The Company funded the acquisition with cash on hand.

Changes in Estimates
Aggregate net changes in estimates reflected an increase to income before income taxes of $15.8 million ($0.53 per diluted share), an increase of $25.0 million ($0.83 per diluted share), and an increase of $23.4 million ($0.74 per diluted share) during fiscal 2025, 2024, and 2023, respectively. The Company uses its statutory tax rate when calculating the impact to diluted earnings per share.
Revenues recognized from previously satisfied performance obligations were $0.2 million, $0.7 million, and $1.7 million for fiscal 2025, 2024, and 2023, respectively. The change in revenues generally relates to final true-up adjustments for estimated award or incentive fees in the period in which the customers' final performance score was received or when it can be determined that more objective, contractually-defined criteria have been fully satisfied.
Remaining Performance Obligations
As of June 30, 2025, the Company had $12.1 billion of remaining performance obligations and expects to recognize approximately 44% and 63% over the next 12 and 24 months, respectively, with the remainder to be recognized thereafter.

Sales of Receivables Sales of Receivables
On December 20, 2024, the Company amended its Master Accounts Receivable Purchase Agreement (MARPA) with MUFG Bank, Ltd. (Purchaser), for the sale of certain designated eligible U.S. government receivables. The amendment extended the term of the MARPA to December 19, 2025. Under the MARPA, the Company can sell eligible receivables, including certain billed and unbilled receivables up to a maximum amount of $300.0 million. The Company’s receivables are sold under the MARPA without recourse for any U.S. government credit risk.
The Company accounts for receivable transfers under the MARPA as sales under ASC 860, Transfers and Servicing, and derecognizes the sold receivables from its balance sheets. The fair value of the sold receivables approximated their book value due to their short-term nature.
The Company does not retain an ongoing financial interest in the transferred receivables other than cash collection and administrative services. The Company estimated that its servicing fee was at fair value, and therefore, no servicing asset or liability related to these receivables was recognized as of June 30, 2025. Proceeds from the sold receivables are reflected within operating activities on the consolidated statements of cash flows.

Fair Value Disclosures [Abstract]  
Fair Value Measurements Fair Value Measurements
ASC 820, Fair Value Measurements and Disclosures, establishes a framework for measuring fair value and categorizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than quoted prices in active markets that are observable, either directly or indirectly, or quoted prices that are not active (Level 2); and unobservable inputs in which there is little or no market data which requires development of assumptions that market participants would use in pricing the asset or liability (Level 3).
The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and amounts included in other current assets and current liabilities that meet the definition of a financial instrument approximate fair value because of the short-term nature of these amounts.
The financial instruments measured at fair value on a recurring basis consist of the following (dollars in thousands):

The outstanding principal amount of the Company’s long-term debt approximates its fair value at June 30, 2025. The fair value of the Company’s debt was estimated using Level 2 inputs based on market data on companies with a corporate rating similar to CACI’s that have recently priced credit facilities.
The Company uses interest rate swap agreements to manage its interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves.
The Company recognized contingent consideration liabilities in connection with certain acquisitions, representing potential earnout payments and other contingent payments. The fair values of these liabilities were determined using a valuation model, which included an assessment of the most likely outcome, assumptions related to projected earnings of the acquired company, and the application of a discount rate, when applicable. Fair value of contingent consideration is reassessed quarterly, including an analysis of the significant inputs used in the evaluation, as well as the accretion of the discount. Changes in the fair value of contingent consideration are reflected within indirect costs and selling expenses

Credit Facility Agreement
The Company has a $3,200.0 million credit facility (the Credit Facility), which consists of a $1,975.0 million revolving credit facility (the Revolving Facility) and a $1,225.0 million term loan (the Term Loan). The Revolving Facility is a secured facility that permits continuously renewable borrowings of up to $1,975.0 million and has sub-facilities of $100.0 million for same-day swing line loan borrowings and $25.0 million for stand-by letters of credit. The Credit Facility has an accordion feature that may provide additional borrowings. The Company pays a quarterly facility fee for the unused portion of the Revolving Facility.
The Term Loan is a five-year secured facility, under which principal payments are due in quarterly installments of $15.3 million until the balance is due in full at maturity. The interest rates applicable to the loans under the Credit Facility are floating interest rates that, at the Company’s option, equal a base rate or a Secured Overnight Financing Rate (SOFR) rate, plus in each case, an applicable margin based upon the Company’s consolidated total net leverage ratio.
The Credit Facility requires the Company to comply with certain financial covenants, including a maximum total leverage ratio and a minimum interest coverage ratio. The Credit Facility includes customary negative covenants restricting or limiting the Company’s ability to guarantee or incur additional indebtedness, grant liens or other security interests to third parties, make loans or investments, transfer assets, declare dividends or redeem or repurchase capital stock or make other distributions, prepay subordinated indebtedness and engage in mergers, acquisitions or other business combinations, in each case except as expressly permitted under the Credit Facility. As of June 30, 2025, the Company was in compliance with all of the financial covenants. A majority of the Company’s assets serve as collateral under the Credit Facility. The Credit Facility includes cross-default provisions with our other debt instruments.
Term Loan B Facility
On October 30, 2024, to provide additional financial flexibility for the Company in connection with the Azure Summit acquisition, the Company completed a senior secured Term Loan B Facility in an aggregate principal amount of $750.0 million. The Term Loan B Facility is a seven-year facility, under which principal payments are due in quarterly installments of $1.9 million from March 2025 until the balance is due in full at maturity. The interest rates applicable to the loans under the Term Loan B Facility are floating interest rates that, at the Company’s option, equal a base rate or a SOFR rate, plus in each case, an applicable margin.
The Term Loan B Facility requires the Company to comply with certain customary negative covenants that restrict or limit our ability to guarantee or incur additional indebtedness, grant liens or other security interests to third parties, make loans or other investments, transfer or dispose of assets, declare dividends, redeem or repurchase capital stock or make other distributions in respect of capital stock, prepay certain subordinated indebtedness and engage in mergers, acquisitions or other business combinations, in each case, except as expressly permitted under the Term Loan B Facility. The Term Loan B Facility includes cross-default provisions with our other debt instruments.
2033 Senior Unsecured Notes
On June 2, 2025, CACI issued 6.375% fixed-rate unsecured senior notes with an aggregate principal amount of $1,000.0 million (the “2033 Notes”). Net proceeds of $989.8 million were received as a result of the issuance after withheld underwriter fees, which are amortized and recorded as interest expense over the term of the 2033 Notes. All of the net proceeds were used to repay outstanding borrowings under the Revolving Facility.
Interest is payable semi-annually in arrears on June 15 and December 15, commencing on December 15, 2025. The principal is due in full at maturity.
The 2033 Notes are subordinated to existing senior secured indebtedness, including the Credit Facility and Term Loan B Facility.
Prior to June 15, 2028, the Company may redeem the 2033 Notes, in whole or in part, at a redemption price of the respective principal amount plus a make-whole premium and accrued and unpaid interest to the date of redemption. Prior to June 15, 2028, the Company may redeem up to 40% of the aggregate principal amount of the 2033 Notes with net cash proceeds of certain equity offerings of the Company at a redemption price of 106.375% of the respective principal amount plus accrued and unpaid interest to the date of redemption.
On or after June 15, 2028, June 15, 2029, and June 15, 2030, and thereafter, the Company may redeem the 2033 Notes, in whole or in part, at a redemption price equal to 103.188%, 101.594%, and 100% of the related principal amount, respectively, plus accrued and unpaid interest to the date of redemption.
Upon the occurrence of a change of control event accompanied by a ratings decline with respect to the 2033 Notes, each note holder may require the Company to repurchase the respective notes held, in whole or in part, at a redemption price of 101% of the related principal amount plus accrued and unpaid interest to the date of redemption.
The 2033 Notes include certain covenants restricting or limiting the Company’s ability to guarantee or incur additional indebtedness, grant liens or other security interests to third parties, and enter into sale and leaseback transactions. The 2033 Notes includes cross-default provisions with our other debt instruments.
All debt issuance costs are amortized using the effective interest rate over the life of the loan.

Cash Flow Hedges
The Company periodically uses derivative financial instruments as part of a strategy to manage exposure to market risks associated with interest rate fluctuations. The Company has entered into several floating-to-fixed interest rate swap agreements for a total notional amount of $1,000.0 million, which hedge a portion of the Company’s floating rate indebtedness. Under these agreements, the Company pays a fixed rate and receives SOFR. As of June 30, 2025 and 2024, the weighted average fixed rates of the Company’s interest rate swaps were 2.93% and 2.86%, respectively. The counterparties to all swap agreements are financial institutions.
The Company has designated the swaps as cash flow hedges. Unrealized gains are recognized as assets while unrealized losses are recognized as liabilities. The interest rate swap agreements are highly correlated to the changes in interest rates to which the Company is exposed. Realized gains and losses in connection with each required interest payment are reclassified from accumulated other comprehensive income or loss to interest expense in a manner that matches the timing of the earnings impact of the hedge transactions.

On January 30, 2023, CACI entered into an Accelerated Share Repurchase (ASR) Agreement with Citibank, N.A (Citibank). Under the ASR Agreement, we paid $250.0 million to Citibank and received an initial delivery of approximately 0.7 million shares of common stock, which became treasury shares. On August 4, 2023, the ASR was completed and the Company received an additional 0.1 million shares of common stock, which became treasury shares. In total, the Company repurchased 0.8 million shares at an average price per share of $303.57.

Plan Summaries
The stock-based compensation plans approved by the stockholders of the Company are the 2016 Amended and Restated Incentive Compensation Plan (the 2016 Plan), the Employee Stock Purchase Plan (ESPP), the Management Stock Purchase Plan (MSPP), and the Director Stock Purchase Plan (DSPP).
The 2016 Plan provides CACI employees and members of the board of directors the opportunity to receive various types of stock-based compensation awards, which include, among others, RSUs and PRSUs. As of June 30, 2025, the total number of shares authorized for issuance under the 2016 Plan is 2,400,000. As of June 30, 2025, 926,343 shares remain available for issuance.
As of June 30, 2025, we have outstanding RSU and PRSU awards under the 2016 Plan. Employee RSUs generally vest over a three-year service period in equal installments on each anniversary of the grant date. Employee PRSUs cliff vest at the end of the third fiscal year following the grant date, subject to meeting the minimum service requirements and the Company’s achievement of certain financial metrics, with the number of shares issued, if any, ranging up to 200% of the specified target shares. Directors receive an annual RSU grant as part of their compensation, which vests in four equal quarterly installments.
The ESPP allows eligible full-time employees to purchase shares of the Company's common stock at 95% of the fair market value of share of common stock on the last day of the quarter. The ESPP is a qualified plan under Section 423 of the Internal Revenue Code and is considered non-compensatory for financial reporting purposes. The MSPP allows eligible employees with stock holding requirements a mechanism to receive RSUs at a discount in lieu of up to 100% of their annual bonus compensation. The discount is recognized as stock compensation expense ratably over the three-year vesting period. The DSPP allows directors to elect to receive RSUs at the market price of the Company's common stock on the date of the award in lieu of up to 100% of their annual retainer fees. As of June 30, 2025, there are 1,500,000, 500,000, and 75,000 shares authorized for issuance under the ESPP, MSPP and DSPP, respectively, and these plans are not material to our consolidated financial statements.

During fiscal 2023, a provision of the TCJA took effect that eliminated the option to deduct domestic research and development costs in the year incurred and instead requires taxpayers to capitalize and amortize such costs over five years. This provision decreased fiscal 2025 and 2024 cash flows from operations by $47.4 million and $73.9 million, respectively, and increased net deferred tax assets by a similar amount. On July 4, 2025, the President signed into law the One Big Beautiful Bill Act (OBBBA). The OBBBA, among other things, enacted a provision that allows immediate deduction of domestic research and development costs in the year incurred.
The Company’s cash tax payments will benefit materially from this provision in fiscal 2026. We will continue to evaluate the OBBBA but do not expect other tax provisions to have a material impact on the Company’s effective tax rate or its results of operations, financial position, and cash flows.
The Company is subject to income taxes in the U.S. and various state and foreign jurisdictions. Tax statutes and regulations within each jurisdiction are subject to interpretation and require the application of significant judgment. In the fourth quarter of fiscal 2025, Internal Revenue Service (IRS) concluded examinations of federal income tax audit for fiscal 2017 through 2021. Based on the IRS audit results, approximately $55.3 million of federal income tax receivables have been classified as short term as of June 30, 2025. The Company is currently under examination for fiscal 2019-2020 in one state jurisdiction and fiscal 2022-2023 in another state. The Company does not expect the resolution of either state examination to have a material impact on its results of operations, financial position, and cash flows.
U.S. income taxes have not been provided for undistributed earnings of foreign subsidiaries that have been permanently reinvested outside the U.S. As of June 30, 2025, the estimated deferred tax liability associated with these undistributed earnings is approximately $2.9 million.

The Company’s total liability for unrecognized tax benefits as of June 30, 2025, 2024 and 2023 was approximately $30.2 million, $73.0 million and $153.9 million, respectively. During fiscal 2025, the Company reduced its unrecognized tax benefits following resolution of the federal income tax audit. During fiscal 2024, the Company reduced its unrecognized tax benefit, primarily due to completing a detailed analysis of capitalized research and development costs which considered recent guidance issued by the IRS.
The Company recognizes net interest and penalties as a component of income tax expense. Over the next 12 months, the Company does not expect a significant increase or decrease in the unrecognized tax benefits recorded at June 30, 2025. As of June 30, 2025, the entire balance of unrecognized tax benefits is included in deferred taxes and other long-term liabilities.
The Organisation for Economic Co-operation and Development has a framework to implement a global minimum corporate tax of 15% for companies with global revenues and profits above certain thresholds (referred to as Pillar 2). While it is uncertain whether the U.S. will enact legislation to adopt Pillar 2, certain countries in which we operate have adopted legislation, and other countries are in the process of introducing legislation to implement Pillar 2. The Company does not expect Pillar 2 to have a material impact on its effective tax rate or its results of operation, financial position, and cash flows.

Retirement Plans Retirement Plans
The Company sponsors various defined contribution plans, in which most employees are eligible to participate. The total plan expense for fiscal 2025, 2024, and 2023 was $84.4 million, $78.7 million, and $99.0 million, respectively.
CACI $MART Plan
The Company offers the CACI $MART Plan, a defined contribution plan to its eligible employees. The Company makes minimum matching contributions that vest after three years of continuous service. Contribution expense for the plan for fiscal 2025, 2024, and 2023 was $74.7 million, $65.8 million, and $52.7 million, respectively.
Supplemental Retirement Savings Plan
The Company maintains the CACI International Inc Group Executive Retirement Plan (the Supplemental Retirement Savings Plan). The Supplemental Retirement Savings Plan is a non-qualified defined contribution supplemental retirement savings plan for certain key employees whereby participants may elect to defer a portion of their compensation. The Company contributes 5% of participant annual compensation exceeding the limit as set forth in IRC 401(a)(17) (currently $350,000 per year) and may make additional discretionary contributions. These contributions vest over five-years from enrollment but vest immediately upon a change of control. Participant accounts are credited with the rate of return based on the investment options and asset allocations selected by the Participant. Distributions from the Supplemental Retirement Savings Plan are available upon retirement, termination, death, total disability, or through in-service withdrawals.
As of June 30, 2025 and 2024, Supplemental Retirement Savings Plan obligations due to participants totaled $125.4 million and $122.5 million, respectively, of which the current portion is included in accrued compensation and benefits. Supplemental Retirement Savings Plan expense for fiscal 2025, 2024, and 2023 was $7.2 million, $6.9 million, and $4.5 million, respectively.
We invest in corporate owned life insurance (COLI) products that are held in a Rabbi Trust to fund the Supplemental Retirement Savings Plan obligations. The COLI investments are recorded at cash surrender value and are presented as supplemental retirement savings plan assets on the consolidated financial statements. Gains and losses recognized on the COLI products are recorded in Indirect costs and selling expenses on the consolidated statements of operations. We recorded a net gain of $5.2 million, $5.2 million, and $3.3 million for fiscal 2025, 2024, and 2023, respectively.

Legal Proceedings
The Company is involved in various claims, lawsuits, and administrative proceedings arising in the normal course of business, none of which, based on current information, are expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows.
On November 12, 2024, a jury reached a $42 million judgment against the Company in an ongoing civil suit alleging that the Company’s employees had conspired with the U.S. military, which lead to acts of wrongdoings committed by the U.S. military against the plaintiffs. On November 25, 2024, the Company filed a motion for dismissal as a matter of law, enumerating numerous grounds. On January 10, 2025, the motion was denied, and the Company filed a notice of appeal to the U.S. Court of Appeals. The Court of Appeals established a briefing schedule, which concluded on July 25, 2025. The Court of Appeals has scheduled oral argument for September 9, 2025. The Company is vigorously defending the proceedings and continues to believe that the plaintiffs’ position is completely without merit. No amounts have been recognized on our consolidated financial statements.
Government Contracting
Payments to the Company on cost-plus-fee and time-and-materials contracts are subject to adjustment upon audit by the Defense Contract Audit Agency (DCAA) and other government agencies that do not utilize DCAA’s services. The DCAA has completed audits of the Company’s annual incurred cost proposals through fiscal year ended June 30, 2023. The Company is still negotiating the results of prior years’ audits with the respective cognizant contracting officers and believes its reserves for such are adequate. In the opinion of management, adjustments that may result from these audits and the audits not yet started are not expected to have a material effect on the Company’s financial position, results of operations, or cash flows as the Company has accrued its best estimate of potential disallowances. Additionally, the DCAA continually reviews the cost accounting and other practices of government contractors, including the Company. In the course of those reviews, cost accounting and other issues are identified, discussed and settled.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
Risk Management and Strategy
CACI is committed to maintaining a robust cybersecurity management and oversight program to mitigate cybersecurity risks to our systems and to protect both our and our customers' confidential and sensitive information. We employ technologies and have implemented programs and processes to continually assess, identify, and manage cybersecurity risks as we aim to incorporate industry best practices throughout our cybersecurity program.
CACI’s cybersecurity program is integrated into our overall risk management program and is primarily managed by our Chief Information Security Officer (CISO) who is responsible for coordinating cross-functional internal and external resources to establish processes and procedures to monitor potential cybersecurity risks, identify cybersecurity incidents, implement appropriate mitigation measures, report cybersecurity breaches, and maintain our cybersecurity program. Our CISO has extensive experience assessing and managing cybersecurity programs and cybersecurity risk and monitors prevention, detection, mitigation, and remediation efforts through regular communication and reporting from experienced cybersecurity professionals in the information security team, supplemented by technological tools and software. We continuously monitor cybersecurity threats and assess the robustness of our mitigation and prevention measures through routine internal and independent audits, threat simulations, vulnerability and penetration testing, and employee cybersecurity training. Our cybersecurity program is designed to be aligned with applicable industry standards, and we continue to invest in capabilities to protect all information assets in our possession.
As a government contractor, we have designed our cybersecurity risk management program to align with the National Institute of Standards and Technology (NIST) standards and comply with extensive regulations, including but not limited to U.S. government cybersecurity regulations. Additionally, our cybersecurity program is routinely assessed by the government, and our network is penetration tested biannually by a third-party independent assessor. We work closely with our subcontractors and suppliers to identify and manage cybersecurity risks. We require them to comply with applicable laws and regulations, including implementing certain security controls and complying with certain reporting obligations. Although we perform due diligence on all service providers to identify potential cybersecurity risks and establish controls through onboarding procedures and contractual requirements, our ability to monitor the cybersecurity practices of our service providers and ensure that we can prevent or mitigate the risk of any compromise or failure in the information system, software, networks, and other assets owned or controlled by our vendors is limited.
In the event of a cybersecurity incident, the Company has established an incident response plan to address the matter promptly and effectively. Our CISO leads our Cybersecurity Incident Response Team (CIRT) that is responsible for leading and coordinating CACI’s response to cybersecurity incidents in accordance with CACI’s established cybersecurity incident response plan and response processes. In accordance with these policies, cybersecurity events and data incidents are evaluated, ranked by severity, and prioritized for escalation to CACI’s Executive Incident Assessment Committee. The plan includes procedures for investigating and containing incidents, notifying affected parties, and implementing corrective actions to prevent future occurrences.

Summary of Significant Accounting Policies (Policies)
12 Months Ended
Jun. 30, 2025
Accounting Policies [Abstract]  
Use of Estimates
Use of Estimates
The preparation of financial statements in conformity with generally accepted accounting principles in the U.S. (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reported periods. The most significant of these estimates and assumptions relate to estimating contract revenues and costs, measuring progress against the Company’s performance obligations, assessing the fair value of acquired assets and liabilities accounted for through business acquisitions, valuing and determining the amortization periods for long-lived intangible assets, assessing the recoverability of long-lived assets, reserves for accounts receivable, and reserves for contract related matters. Management evaluates its estimates on an ongoing basis using the most current and available information. However, actual results may differ significantly from estimates. Changes in estimates are recorded in the period in which they become known.
Business Combinations
Business Combinations
The Company records all tangible and intangible assets acquired and liabilities assumed in a business combination at fair value as of the acquisition date, with any excess purchase consideration recorded as goodwill. For contingent purchase consideration, a liability is recognized at fair value as of the acquisition date with subsequent fair value adjustments recorded in operations. The Company uses various valuation methods, including the relief-from-royalty method of the income approach, to determine the fair value of acquired assets and liabilities assumed. The use of these methods requires management to make significant judgments about expected future cash flows, weighted average cost of capital, discount rates, royalty rates, and expected long-term growth rates. During the measurement period, not to exceed one year from the acquisition date, the Company may adjust provisional amounts recorded to reflect new information subsequently obtained regarding facts and circumstances that existed as of the acquisition date.
Acquisition and Integration Costs
Acquisition and Integration Costs
Costs associated with legal, financial, and other professional advisors related to acquisitions, whether successful or unsuccessful, as well as applicable integration costs are expensed as incurred.
Revenue Recognition
Revenue Recognition
The Company generates almost all of our revenues from three different types of contractual arrangements with the U.S. government: cost-plus-fee, fixed-price, and time-and-materials contracts. Our contracts with the U.S. government are generally subject to the Federal Acquisition Regulation (FAR) and are competitively priced based on estimated costs of providing the contractual goods or services.
We account for a contract when the parties have approved the contract and are committed to perform on it, the rights of each party and the payment terms are identified, the contract has commercial substance, and collectability is probable. At contract inception, the Company determines whether the goods or services to be provided are to be accounted for as a single performance obligation or as multiple performance obligations. This evaluation requires professional judgment as it may affect the timing and pattern of revenue recognition. If multiple performance obligations are identified, we generally use the cost plus a margin approach to determine the relative standalone selling price of each performance obligation.
When determining the total transaction price, the Company identifies both fixed and variable considerations within the contract. Variable consideration includes any amount within the transaction price that is not fixed, such as: award or incentive fees; performance penalties; unfunded contract value; or other similar items. For our contracts with award or incentive fees, the Company estimates the total amount of award or incentive fee expected to be recognized into revenues. Throughout the performance period, the Company recognizes as revenue a constrained amount of variable consideration only to the extent that it is probable that a significant reversal of the cumulative amount recognized to date will not be required in a subsequent period. The Company’s estimate of variable consideration is periodically adjusted based on significant changes in relevant facts and circumstances. In the period in which the Company can calculate the final amount of award or incentive fee earned based on the receipt of the customers' final performance score or the determination that more objective, contractually-defined criteria have been fully satisfied, the Company will adjust its cumulative revenue recognized to date on the contract.
The Company generally recognizes revenues over time throughout the performance period as the customer simultaneously receives and consumes the benefits provided on services-type revenue arrangements. This continuous transfer of control for U.S. government contracts is supported by the unilateral right of the customer to terminate the contract for a variety of reasons without having to provide justification for its decision. For services-type revenue arrangements in which there are a repetitive amount of services that are substantially the same from one month to the next, the Company applies the series guidance. The Company uses a variety of input and output methods that approximate the progress towards complete satisfaction of the performance obligation, including costs incurred, labor hours expended, and time-elapsed measures for fixed-price stand ready obligations. For certain contracts, primarily cost-plus and time-and-materials services-type revenue arrangements, the Company applies the right-to-invoice practical expedient in which revenues are recognized in direct proportion to the Company’s present right to consideration for progress towards the complete satisfaction of the performance obligation.
When a performance obligation has a significant degree of interrelation or interdependence between one month’s activities and the next, when there is an award or incentive fee, or when there is a significant degree of customization or modification, the Company generally records revenue using a percentage of completion method. For these revenue arrangements, substantially all revenues are recognized over time using a cost-to-cost input method based on the ratio of costs incurred to date to total estimated costs at completion. When estimates of total costs to be incurred on a contract exceed total revenue, a provision for the entire loss on the contract is recorded in the period in which the loss is determined.
Contract modifications are reviewed to determine whether they should be accounted for as part of the original performance obligation or as a separate contract. Contract modifications that add distinct goods or services and increase the contract value by an amount that reflects the standalone selling price are accounted for as separate contracts. When the contract modification includes goods or services that are not distinct from those already provided, the Company records a cumulative adjustment to revenues based on a remeasurement of progress towards the complete satisfaction of the not yet fully delivered performance obligation.
Based on the critical nature of our contractual performance obligations, the Company may proceed with work based on customer direction prior to the completion and signing of formal contract documents. The Company has a formal review process for approving any such work that considers previous experiences with the customer, communications with the customer regarding funding status, and the Company’s knowledge of available funding for the contract or program.
Costs of Revenues
Costs of Revenues
Costs of revenues includes all direct contract costs such as labor, materials, subcontractor costs, and indirect costs that are allowable and allocable to contracts under federal procurement standards. Costs of revenues also includes expenses that are unallowable under applicable procurement standards and are not allocable to contracts for billing purposes. Such unallowable expenses do not directly generate revenues but are necessary for business operations.
Changes in Estimates on Contracts
Changes in Estimates on Contracts
The Company recognizes revenues on many of its fixed-price, award fee, and incentive fee arrangements over time primarily using a cost-to-cost input method based on the ratio of costs incurred to date to total estimated costs at completion. The process requires the Company to use professional judgment when assessing risks, estimating contract revenues and costs, estimating variable consideration, and making assumptions for schedule and technical issues. The Company periodically reassesses its assumptions and updates its estimates as needed.
Contract Balances
Contract Balances
Contract assets include unbilled receivables in which our right to consideration is conditional on factors other than the passage of time. Contract assets exclude billed and billable receivables.
In addition, the costs to fulfill and obtain a contract are considered for capitalization based on contract specific facts and circumstances. The incremental costs to fulfill a contract (e.g., ramp up costs at the beginning of the period of performance) may be capitalized when costs are incurred prior to satisfying a performance obligation. The incremental costs of obtaining a contract (e.g., sales commissions) are capitalized as an asset when the Company expects to recover them either directly or indirectly through the revenue arrangement’s profit margins. These capitalized costs are subsequently expensed over the revenue arrangement’s period of performance. The Company has elected to apply the practical expedient to immediately expense the costs to obtain a contract when the performance obligation will be completed within twelve months of contract inception.
Contract assets are periodically reassessed based on reasonably available information as of the balance sheet date to ensure they do not exceed their net realizable value.
Contract liabilities primarily include advance payments received from a customer in excess of revenues that may be recognized as of the balance sheet date. The advance payment is subsequently recognized into revenues as the performance obligation is satisfied.
Remaining Performance Obligations
Remaining Performance Obligations
Remaining performance obligations (RPO) represent the expected revenues to be recognized for the satisfaction of remaining performance obligations on existing contracts. This balance excludes unexercised contract option years and task orders that may be issued underneath an indefinite delivery/indefinite quantity vehicle until such task orders are awarded. The RPO balance generally increases with the execution of new contracts and converts into revenues as contractual performance obligations are satisfied. The Company continues to monitor this balance as it is subject to change from execution of new contracts, contract modifications or extensions, government deobligations, or early terminations.
Cash and Cash Equivalents
Cash and Cash Equivalents
The Company considers all investments with an original maturity of three months or less on their trade date to be cash equivalents. The Company classifies investments with an original maturity of more than three months but less than twelve months on their trade date as short-term marketable securities.
Receivables
Receivables
Receivables include billed and billable receivables, and unbilled receivables. Billable and unbilled receivables are recognized at estimated realizable value, substantially all of which are expected to be billed and collected generally within one year. When events or conditions indicate that amounts outstanding from customers may become uncollectible, an allowance is estimated and recorded. Upon determination that a specific receivable is uncollectible, the receivable is written off against the allowance for expected credit losses.
Concentrations of Credit Risk
Concentrations of Credit Risk
Financial instruments that potentially subject the Company to credit risk include accounts receivable and cash equivalents. Management believes that credit risk related to the Company’s accounts receivable is limited due to a large number of customers in differing segments and agencies of the U.S. government. Accounts receivable credit risk is also limited due to the creditworthiness of the U.S. government. Management believes the credit risk associated with the Company’s cash equivalents is limited due to the creditworthiness of the obligors of the investments underlying the cash equivalents. In addition, although the Company maintains cash balances at financial institutions that exceed federally insured limits, these balances are placed with high quality financial institutions.
Inventories
Inventories
Inventories are stated at the lower of cost (average cost or first-in, first-out) or net realizable value and are included in prepaid expenses and other current assets on the consolidated balance sheets. The Company periodically assesses its current inventory balances and records a provision for damaged, deteriorated, or obsolete inventory based on historical patterns and forecasted sales.
Goodwill and Intangible Assets
Goodwill and Intangible Assets
Goodwill represents the excess of the fair value of consideration paid for an acquisition over the fair value of the net assets acquired as of the acquisition date. The Company evaluates goodwill for both of its reporting units for impairment annually on the first day of the fiscal fourth quarter, or whenever events or circumstances indicate that the carrying value may not be recoverable. The evaluation includes a qualitative assessment or a quantitative assessment that compares the fair value of the relevant reporting unit to its respective carrying value, including goodwill, and utilizes both income and market approaches. The analysis relies on significant judgments and assumptions about expected future cash flows, weighted average cost of capital, discount rates, expected long-term growth rates, and financial measures derived from observable market data of comparable public companies.
Intangible assets with finite lives are amortized using the method that best reflects how their economic benefits are utilized or, if a pattern of economic benefits cannot be reliably determined, on a straight-line basis over their estimated useful lives, which is generally over periods ranging from one to twenty-five years. Intangible assets with finite lives are assessed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable at the asset group level.
Property, Plant and Equipment
Property, Plant, and Equipment
Purchases of property, plant, and equipment are capitalized at cost. Depreciation of equipment and furniture has been provided over the estimated useful life of the respective assets (ranging from three to eight years) using the straight-line method. Leasehold improvements are generally amortized using the straight-line method over the remaining lease term or the useful life of the improvements, whichever is shorter. Repairs and maintenance costs are expensed as incurred.
The Company evaluates its long-lived assets for potential impairment whenever there is evidence that events or changes in circumstances indicate that the carrying value may not be recoverable and the carrying amount of the asset exceeds its estimated fair value at the asset group level.
External Software Development Costs
External Software Development Costs
Costs incurred in creating software to be sold or licensed for external use are expensed as incurred until technological feasibility has been established. Technological feasibility is established upon completion of a detailed program design or, in its absence, completion of a working model. Thereafter, all such software development costs are capitalized and subsequently reported at the lower of unamortized cost or estimated net realizable value. Capitalized costs are amortized on a straight-line basis over the remaining estimated economic life of the software.
Leases
Leases
The Company enters into contractual arrangements primarily for the use of real estate facilities, IT equipment, and certain other equipment. These arrangements contain a lease when the Company controls the underlying asset and has the right to obtain substantially all of the economic benefits or outputs from the asset. All of the Company’s leases are operating leases.
The Company records a right-of-use (ROU) asset and lease liability as of the lease commencement date equal to the present value of the remaining lease payments. Most of the Company’s leases do not provide an implicit rate that can be readily determined. Therefore, the Company uses a discount rate based on its incremental borrowing rate, which is determined using its credit rating and information available as of the commencement date. The ROU asset is then adjusted for initial direct costs and certain lease incentives included in the contractual arrangement. The Company combines and accounts for lease and non-lease components as a single component for facility leases. The Company has elected the practical expedient to not recognize lease liabilities and ROU assets for short-term equipment and other non-facility leases. Operating lease arrangements may contain options to extend the lease term or for early termination. The Company accounts for these options when exercise is reasonably certain. ROU assets are evaluated for impairment in a manner consistent with the treatment of other long-lived assets.
Operating lease expense is recognized on a straight-line basis over the lease term and is recorded primarily within indirect costs and selling expenses on the consolidated statements of operations. Variable lease expenses are recorded in the period they are incurred and are excluded from the ROU asset and lease liability.
Earnings Per Share
Earnings Per Share
Basic earnings per share excludes dilution and is computed by dividing income by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock but not securities that are anti-dilutive. Using the treasury stock method, diluted earnings per share includes the incremental effect of restricted stock units (RSUs) that are no longer subject to a market or performance condition. Information about the weighted average number of basic and diluted shares is presented in “Note 14 – Earnings Per Share”.
Stock-Based Compensation
Stock-Based Compensation
We issue stock-based awards as compensation to employees and directors in the form of Restricted Stock Units (RSUs) and Performance-based Restricted Stock Units (PRSUs). These awards are accounted for as equity awards. We recognize stock-based compensation expense net of estimated forfeitures on a straight-line basis over the underlying award’s requisite service period, as measured using the award’s grant date fair value. The grant date fair value is based on the closing market price of our common stock on the grant date. For PRSUs, we assess the probability of achieving the performance conditions at each reporting period and adjust compensation expense based on the number of shares we expect to issue.
Income Taxes
Income Taxes
Income taxes are accounted for using the asset and liability method which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities due to a change in tax rates is recognized in income in the period that includes the enactment date. Estimates of the realizability of deferred tax assets are based on the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies.
Liabilities for uncertain tax positions are recognized when it is more likely than not that a tax position will not be sustained upon examination and settlement with taxing authorities. Liabilities for uncertain tax positions are measured based upon the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. Tax penalties and interest are included in income tax expense.
Foreign Currency
Foreign Currency
The assets and liabilities of the Company’s foreign subsidiaries whose functional currency is other than the U.S. dollar are translated at the exchange rate in effect on the reporting date, and income and expenses are translated at the weighted average exchange rate during the period. The Company’s primary practice is to negotiate contracts in the same currency in which the predominant expenses are incurred, thereby mitigating the exposure to foreign currency fluctuations. The net translation gains and losses are recorded as accumulated other comprehensive income (loss) in shareholders’ equity. Foreign currency transaction gains and losses are recorded as incurred in indirect costs and selling expenses on the consolidated statements of operations.
Commitments and Contingencies
Commitments and Contingencies
Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated.
Recent Accounting Pronouncements Recent Accounting Pronouncements
In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, Improvements to Reportable Segment Disclosures, which requires disclosure of significant segment expenses and other segment items in annual and interim periods. The Company adopted the annual disclosure requirements in fiscal 2025 and will adopt the interim disclosure requirements in fiscal 2026. See "Note 18 – Business Segments" for additional information.
In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which requires disaggregated information about an entity’s effective tax rate reconciliation as well as information on income taxes paid. The ASU will be effective beginning with our annual fiscal 2026 financial statements and should be applied prospectively. Retrospective application is permitted. We are currently evaluating the impacts of the new standard on our income tax disclosures.
In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, to enhance the transparency of certain expense disclosures. The ASU requires disclosure of specific types of expenses included in the expense captions of the consolidated statements of operations. The ASU will be effective beginning with our annual fiscal 2028 financial statements and may be adopted prospectively or retrospectively. We are currently evaluating the impacts of the new standard.
