Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings and Other Commitments and Contingencies	Note 13 – Legal Proceedings and Other Commitments and Contingencies Legal Proceedings The Company is involved in various claims, lawsuits, and administrative proceedings arising in the ordinary course of business. Based on current information and recent legal developments, management does not believe that any of these matters, individually or in the aggregate, are reasonably likely to have a material adverse effect on the Company’s financial position, results of operations, or cash flows. The Company is defending a civil lawsuit in which plaintiffs allege that Company employees conspired with the U.S. military in connection with alleged acts of wrongdoing. The plaintiffs assert claims under the Alien Tort Statute (ATS). In November 2024, a jury returned a $42 million verdict against the Company, and on March 12, 2026, the U.S. Court of Appeals for the Fourth Circuit affirmed the judgment. On August 28, 2026, following the Supreme Court’s June 2026 decision in Cisco Systems, Inc. v. Doe, the Fourth Circuit directed the dismissal of the case, unless the plaintiffs seek further rehearing. No petition was filed by the plaintiffs. On October 20, 2026, the Court of Appeals issued the Mandate, returning the case to the District Court. On October 21, the District Court issued an Order reversing and vacating the Judgment entered on January 10, 2025, entering judgment in favor of CACI, and dismissing the case. The Plaintiffs have indicated that they may seek Supreme Court review of the Court of Appeals decision. No amounts have been recognized in our condensed 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 2024. 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. 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.
