Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of CACI International Inc and subsidiaries (CACI or the Company) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and include the assets, liabilities, results of operations, comprehensive income and cash flows for the Company, including its subsidiaries and ventures that are majority-owned or otherwise controlled by the Company. Certain information and note disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information presented not misleading. All intercompany balances and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year presentation. 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 fair value of the Company’s debt outstanding as of December 31, 2024 under its bank credit facility approximates its carrying value. The fair value of the Company’s debt under its bank credit facility was estimated using Level 2 inputs based on market data of companies with a corporate rating similar to CACI’s that have recently priced credit facilities. In the opinion of management, the accompanying unaudited consolidated financial statements reflect all adjustments and reclassifications (all of which are of a normal, recurring nature) that are necessary for the fair presentation of the periods presented. It is suggested that these unaudited consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s latest annual report to the SEC on Form 10-K for the year ended June 30, 2024. The results of operations for the three and six months ended December 31, 2024 are not necessarily indicative of the results to be expected for any subsequent interim period or for the full fiscal year.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Updates Issued but Not Yet Adopted 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 ASU will be effective beginning with our annual fiscal 2025 financial statements, and requires retrospective application to all prior periods presented in the financial statements. We are currently evaluating the impacts of the new standard on our segment disclosures. 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. Accounting Standards Updates Adopted There have been no recently adopted accounting pronouncements that are material to the Company's consolidated financial statements.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Acquisitions	Acquisitions Applied Insight On October 1, 2024, CACI acquired all of the equity interests of AI Corporate Holdings, Inc. and Applied Insight Holdings, LLC (Applied Insight) for purchase consideration of approximately $314.2 million, net of cash acquired, subject to adjustments for working capital and certain other items. 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. At December 31, 2024, the Company had not finalized the determination of fair values allocated to assets and liabilities. The intangible assets consist of customer relationships of $84.3 million and technology of $10.9 million, which will amortize over eight five 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 approximately $1,310.2 million, net of cash acquired, subject to adjustments for working capital and certain other items. Azure Summit advances DoD mission outcomes with its portfolio of high-performance radio frequency technology and engineering talent focused on the electromagnetic spectrum. The Company funded the acquisition with the net proceeds from the new senior secured Term Loan B facility (see “Note 8 – Debt”), borrowings under the revolving credit facility and cash on hand to finance the acquisition. The purchase price was allocated, on a preliminary basis, among assets acquired and liabilities assumed at fair value on the acquisition date, October 30, 2024, based on the best available information, with the excess purchase price recorded as goodwill. As of December 31, 2024, the Company has not finalized the determination of fair values allocated to various assets and liabilities, including, but not limited to, accounts receivables, prepaid expenses and other current assets, intangible assets, accounts payable, accrued compensation and benefits, and goodwill. The allocation of the purchase price is subject to change as the Company continues to obtain and assess relevant information that existed as of the acquisition date. The preliminary allocation of the total estimated purchase consideration is as follows: Accounts receivable, net $ 91,891 Prepaid expenses and other current assets 31,554 Goodwill 543,579 Intangible assets, net 649,500 Property, plant and equipment, net 16,349 Operating lease right-of-use assets 9,607 Other long-term assets 211 Accounts payable (16,010) Accrued compensation and benefits (3,855) Other accrued expenses and current liabilities (4,573) Operating lease liabilities, noncurrent (8,062) Total estimated consideration $ 1,310,191 The goodwill is primarily associated with future customer relationships and an acquired assembled work force. All of the goodwill recognized is tax deductible. The estimated fair value attributed to intangible assets of $649.5 million consists of customer relationships of $270.5 million and technology of $379.0 million. The fair value attributed to intangible assets is being amortized over 10 to 20 years for customer intangibles and over 20 to 25 years for technology. 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. From the October 30, 2024 acquisition date through December 31, 2024, Azure Summit generated $59.9 million of revenues and $10.2 million of net income recognized within the Domestic reportable segment. Azure Summit's net income includes the impact of $9.4 million of intangible amortization from the acquisition date through December 31, 2024. Pro forma results of operations for this acquisition are not presented because the acquisition is not material to the Company's consolidated results of operations. For the six months ended December 31, 2024, total acquisition-related costs of $13.3 million were reported in indirect costs and expenses.

Revenues and Contract Balances	Revenues and Contract Balances Disaggregation of Revenues The Company disaggregates revenues by contract type, customer type, prime vs. subcontractor, and whether the solution provided is primarily Expertise or Technology. These categories represent how the nature, amount, timing, and uncertainty of revenues and cash flows are affected. Disaggregated revenues by contract type were as follows (in thousands): Three Months Ended December 31, 2024 Six Months Ended December 31, 2024 Domestic International Total Domestic International Total Cost-plus-fee $ 1,240,213 $ — $ 1,240,213 $ 2,520,223 $ — $ 2,520,223 Fixed-price 564,784 38,075 602,859 1,004,024 74,091 1,078,115 Time-and-materials 234,159 22,578 256,737 511,230 47,130 558,360 Total $ 2,039,156 $ 60,653 $ 2,099,809 $ 4,035,477 $ 121,221 $ 4,156,698 Three Months Ended December 31, 2023 Six Months Ended December 31, 2023 Domestic International Total Domestic International Total Cost-plus-fee $ 1,102,474 $ — $ 1,102,474 $ 2,236,909 $ — $ 2,236,909 Fixed-price 485,086 34,458 519,544 952,302 69,319 1,021,621 Time-and-materials 192,448 19,468 211,916 385,965 39,586 425,551 Total $ 1,780,008 $ 53,926 $ 1,833,934 $ 3,575,176 $ 108,905 $ 3,684,081 Disaggregated revenues by customer type were as follows (in thousands): Three Months Ended December 31, 2024 Six Months Ended December 31, 2024 Domestic International Total Domestic International Total Department of Defense $ 1,578,733 $ — $ 1,578,733 $ 3,113,266 $ — $ 3,113,266 Federal civilian agencies 433,691 — 433,691 873,062 — 873,062 Commercial and other 26,732 60,653 87,385 49,149 121,221 170,370 Total $ 2,039,156 $ 60,653 $ 2,099,809 $ 4,035,477 $ 121,221 $ 4,156,698 Three Months Ended December 31, 2023 Six Months Ended December 31, 2023 Domestic International Total Domestic International Total Department of Defense $ 1,358,509 $ — $ 1,358,509 $ 2,710,815 $ — $ 2,710,815 Federal civilian agencies 389,942 — 389,942 797,286 — 797,286 Commercial and other 31,557 53,926 85,483 67,075 108,905 175,980 Total $ 1,780,008 $ 53,926 $ 1,833,934 $ 3,575,176 $ 108,905 $ 3,684,081 Disaggregated revenues by prime vs. subcontractor were as follows (in thousands): Three Months Ended December 31, 2024 Six Months Ended December 31, 2024 Domestic International Total Domestic International Total Prime contractor $ 1,808,106 $ 53,992 $ 1,862,098 $ 3,634,869 $ 107,648 $ 3,742,517 Subcontractor 231,050 6,661 237,711 400,608 13,573 414,181 Total $ 2,039,156 $ 60,653 $ 2,099,809 $ 4,035,477 $ 121,221 $ 4,156,698 Three Months Ended December 31, 2023 Six Months Ended December 31, 2023 Domestic International Total Domestic International Total Prime contractor $ 1,588,589 $ 47,788 $ 1,636,377 $ 3,189,680 $ 96,059 $ 3,285,739 Subcontractor 191,419 6,138 197,557 385,496 12,846 398,342 Total $ 1,780,008 $ 53,926 $ 1,833,934 $ 3,575,176 $ 108,905 $ 3,684,081 Disaggregated revenues by expertise or technology were as follows (in thousands): Three Months Ended December 31, 2024 Six Months Ended December 31, 2024 Domestic International Total Domestic International Total Expertise $ 895,890 $ 30,010 $ 925,900 $ 1,852,386 $ 61,779 $ 1,914,165 Technology 1,143,266 30,643 1,173,909 2,183,091 59,442 2,242,533 Total $ 2,039,156 $ 60,653 $ 2,099,809 $ 4,035,477 $ 121,221 $ 4,156,698 Three Months Ended December 31, 2023 Six Months Ended December 31, 2023 Domestic International Total Domestic International Total Expertise $ 830,647 $ 18,894 $ 849,541 $ 1,687,843 $ 39,792 $ 1,727,635 Technology 949,361 35,032 984,393 1,887,333 69,113 1,956,446 Total $ 1,780,008 $ 53,926 $ 1,833,934 $ 3,575,176 $ 108,905 $ 3,684,081 Changes in Estimates Aggregate net changes in estimates for the three and six months ended December 31, 2024 reflected an increase to income before income taxes of $4.0 million ($0.13 per diluted share) and $7.7 million ($0.26 per diluted share), respectively, compared with $14.6 million ($0.49 per diluted share) and $17.0 million ($0.56 per diluted share), for the three and six months ended December 31, 2023. The Company uses its statutory tax rate when calculating the impact to diluted earnings per share. Revenues recognized from previously satisfied performance obligations were not material for the three and six months ended December 31, 2024 and 2023, respectively. The change in revenues recognized from previously satisfied performance obligations generally relates to final true-up adjustments for estimated award or incentive fees in the period in which the customer’s 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 December 31, 2024, the Company had $11.9 billion of remaining performance obligations and expects to recognize approximately 41% and 58% as revenue over the next 12 and 24 months, respectively, with the remainder to be recognized thereafter. Contract Balances Contract balances consisted of the following (in thousands): Description of Contract Related Balance Financial Statement Classification December 31, 2024 June 30, 2024 Billed and billable receivables Accounts receivable, net $ 931,059 $ 885,552 Contract assets – current unbilled receivables Accounts receivable, net 269,624 145,759 Contract assets – current costs to obtain Prepaid expenses and other current assets 6,831 6,142 Contract assets – noncurrent unbilled receivables Accounts receivable, long-term 15,065 13,311 Contract assets – noncurrent costs to obtain Other long-term assets 14,669 12,310 Contract liabilities – current deferred revenue and other contract liabilities Other accrued expenses and current liabilities (135,641) (139,745) Contract liabilities – noncurrent deferred revenue and other contract liabilities Other long-term liabilities (4,292) (4,607) During the three and six months ended December 31, 2024, we recognized $29.4 million and $93.5 million of revenues, respectively, compared with $30.0 million and $94.4 million of revenues for the three and six months ended December 31, 2023, that was included in a previously recorded contract liability as of the beginning of the period.

Transfers and Servicing of Financial Assets [Abstract]
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 December 31, 2024. Proceeds from the sold receivables are reflected in operating cash flows on the statement of cash flows. MARPA activity consisted of the following (in thousands): As of and for the 2024 2023 Beginning balance: $ 250,000 $ 200,000 Sales of receivables 1,897,400 1,518,549 Cash collections (1,873,559) (1,553,194) Outstanding balance sold to Purchaser: (1) 273,841 165,355 Cash collected, not remitted to Purchaser (2) (118,016) (55,492) Remaining sold receivables $ 155,825 $ 109,863 __________________________________________________ (1) For the six months ended December 31, 2024 and 2023, the Company recorded a net cash inflow of $23.8 million and a net cash outflow of $34.6 million in its cash flows from operating activities, respectively, from sold receivables. MARPA cash flows are calculated as the change in the outstanding balance during the fiscal year. (2) Includes the cash collected on behalf of but not yet remitted to Purchaser as of December 31, 2024 and 2023. This balance is included in other accrued expenses and current liabilities as of the balance sheet date.

As amended, the Company’s $3,200.0 million Credit Facility 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 has subfacilities of $100.0 million for same-day swing line loan borrowings and $25.0 million for stand-by letters of credit. The Revolving Facility is a secured facility that permits continuously renewable borrowings of up to $1,975.0 million. As of December 31, 2024, the Company had $1,220.0 million outstanding under the Revolving Facility and no borrowings on the swing line. 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 $7.7 million through December 31, 2023 and $15.3 million thereafter until the balance is due in full on December 13, 2026. As of December 31, 2024, the Company had $1,102.5 million outstanding under the Term Loan. The interest rates applicable to 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. For the three months ended December 31, 2024, the effective interest rate, including the impact of the Company’s floating-to-fixed interest rate swap agreements and excluding the effect of amortization of debt financing costs, for the outstanding borrowings under the Credit Facility was 5.38%. 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 also 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 December 31, 2024, 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. All debt issuance costs are being amortized from the date incurred to the expiration date of the Credit Facility. Term Loan B Facility To provide additional financial flexibility for the Company, in connection with the Azure Summit acquisition, the Company entered into a commitment letter (the “Commitment Letter”), dated September 10, 2024, with JPMorgan Chase Bank, N.A. (“JPMorgan”), pursuant to which JPMorgan committed to provide the entire principal amount of a senior secured bridge loan facility in an aggregate principal amount of up to $750.0 million. No amounts were funded pursuant to the Commitment Letter. On October 30, 2024 the Company completed a new senior secured Term Loan B facility in an aggregate principal amount of $750.0 million, which effectively terminated the Commitment Letter. 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 in October 2031. The interest rates applicable to the Term Loan B facility are floating interest rates that, at the Company’s option, equal a base rate or a term SOFR rate plus an applicable margin. The Company recognized $9.8 million of debt discount and debt issuance costs related to the Term Loan B financing, which were recorded as an offset against the carrying value of debt and are being amortized to interest expense over the life of the Term Loan B facility using the effective interest method. 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 an aggregate notional amount of $1,000.0 million which hedge a portion of the Company’s floating rate indebtedness. The swaps mature at various dates through 2028. 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. The Company does not hold or issue derivative financial instruments for trading purposes. The effect of derivative instruments in the consolidated statements of operations and accumulated other comprehensive loss for the three and six months ended December 31, 2024 and 2023 is as follows (in thousands): Three Months Ended December 31, Six Months Ended December 31, 2024 2023 2024 2023 Gain (loss) recognized in other comprehensive income $ 12,963 $ (12,295) $ 1,342 $ (122) Amounts reclassified to earnings from accumulated other comprehensive loss (4,501) (6,927) (10,556) (13,668) Other comprehensive income (loss), net of tax $ 8,462 $ (19,222) $ (9,214) $ (13,790)

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings and Other Commitments and Contingencies	Legal Proceedings and Other Commitments and Contingencies 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 US military, which lead to acts of wrongdoings committed by the US 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 Company is vigorously defending the proceedings and continues to believe that the plaintiffs’ position is completely without merit. No amounts have been recognized in 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 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. 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 and 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 may be identified, discussed and settled.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes 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. The Company is currently under examination by the Internal Revenue Service for fiscal 2017 through 2021 and one state jurisdiction for fiscal 2019 and 2020. The Company does not expect resolution of these examinations to have a material impact on its results of operations, financial condition or cash flows. During fiscal 2023, a provision of the Tax Cuts and Jobs Act of 2017 (TCJA) went into 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. Based upon our interpretation of the law as currently enacted, we estimate that the fiscal 2025 impact will result in increases of $52.7 million to both our income taxes payable and net deferred tax assets. The future impact of this provision will depend on any guidance issued by the Treasury Department regarding the identification of appropriate costs for capitalization, and the amount of future research and development expenses paid or incurred (among other factors). For the six months ended December 31, 2024, the Company recognized a $25.8 million increase in income taxes payable, with a corresponding increase to net deferred tax assets. The Organisation for Economic Co-operation and Development (OECD) 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. We do not expect Pillar 2 to have a material impact on our effective tax rate or our consolidated results of operation, financial position, and cash flows.

Business Segments	Business Segments The Company reports operating results and financial data in two segments: domestic operations and international operations. Domestic operations provide Expertise and Technology primarily to U.S. federal government agencies. International operations provide Expertise and Technology primarily to international government and commercial customers. The Company evaluates the performance of its operating segments based on net income. Summarized financial information for the Company’s reportable segments is as follows (in thousands): Three Months Ended December 31, Six Months Ended December 31, 2024 2023 2024 2023 Revenues: Domestic $ 2,039,156 $ 1,780,008 $ 4,035,477 $ 3,575,176 International 60,653 53,926 121,221 108,905 Total revenues $ 2,099,809 $ 1,833,934 $ 4,156,698 $ 3,684,081 Net income: Domestic $ 100,999 $ 74,759 $ 203,110 $ 151,303 International 8,939 9,111 27,005 18,614 Total net income $ 109,938 $ 83,870 $ 230,115 $ 169,917

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 financial instruments measured at fair value on a recurring basis consist of the following (in thousands): Description of Financial Instrument Financial Statement Fair Value December 31, 2024 June 30, 2024 Fair Value Contingent consideration Other accrued expenses and current liabilities Level 3 $ (3,420) $ (3,061) Contingent consideration Other long-term liabilities Level 3 $ (5,013) $ (13,737) Interest rate swap agreements Prepaid expenses and other current assets Level 2 $ 988 $ — Interest rate swap agreements Other long-term assets Level 2 $ 20,010 $ 33,327 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 and were $8.7 million and zero for the six months ended December 31, 2024 and 2023, respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements of CACI International Inc and subsidiaries (CACI or the Company) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and include the assets, liabilities, results of operations, comprehensive income and cash flows for the Company, including its subsidiaries and ventures that are majority-owned or otherwise controlled by the Company. Certain information and note disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information presented not misleading. All intercompany balances and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year presentation. 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 fair value of the Company’s debt outstanding as of December 31, 2024 under its bank credit facility approximates its carrying value. The fair value of the Company’s debt under its bank credit facility was estimated using Level 2 inputs based on market data of companies with a corporate rating similar to CACI’s that have recently priced credit facilities. In the opinion of management, the accompanying unaudited consolidated financial statements reflect all adjustments and reclassifications (all of which are of a normal, recurring nature) that are necessary for the fair presentation of the periods presented. It is suggested that these unaudited consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s latest annual report to the SEC on Form 10-K for the year ended June 30, 2024. The results of operations for the three and six months ended December 31, 2024 are not necessarily indicative of the results to be expected for any subsequent interim period or for the full fiscal year.
Accounting Standards Updates Issued but Not Yet Adopted and Accounting Standards Updates Adopted	Accounting Standards Updates Issued but Not Yet Adopted 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 ASU will be effective beginning with our annual fiscal 2025 financial statements, and requires retrospective application to all prior periods presented in the financial statements. We are currently evaluating the impacts of the new standard on our segment disclosures. 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.
