CACI INTERNATIONAL INC /DE/

Evaluation of Disclosure Controls and Procedures

Management with the participation of our principal executive officer (our President, CEO, and Director) and our principal financial officer (our Executive Vice President, Chief Financial Officer (CFO), and Treasurer) evaluated the effectiveness of the Company’s disclosure controls and procedures, as defined in Rules 13a‑15(e) and 15d‑15(e) under the Securities Exchange Act of 1934 (Exchange Act), as of June 30, 2026. Based on this evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Inherent Limitations over Internal Controls

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles (GAAP) and includes those policies and procedures that:

(1)Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the issuer;

(2)Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the issuer are being made only in accordance with authorizations of management and directors of the issuer; and

(3)Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the issuer’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management’s Annual Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Exchange Act. Subsequent to the acquisition of ARKA Group L.P. (ARKA) on March 9, 2026, certain elements of ARKA’s internal control over financial reporting and related processes were integrated into the Company’s existing systems and internal control over financial reporting. Those controls that were not integrated have been excluded from management’s assessment of the effectiveness of internal control over financial reporting as of June 30, 2026, in accordance with SEC guidance that an assessment of recently acquired businesses may be omitted in management’s report on internal control over financial reporting, provided the acquisition took place within twelve months of management’s evaluation. The excluded elements represent 1.5% and 1.0% of our consolidated assets and revenues as of and for the year ended June 30, 2026. We are in the process of integrating the excluded elements of ARKA into our overall internal control over financial reporting process.

Management and with the participation of our CEO and CFO, conducted an evaluation of the effectiveness of CACI’s internal control over financial reporting based on the framework and criteria established in Internal Control-Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management has concluded that CACI’s internal control over financial reporting was effective as of June 30, 2026.

The Company’s independent registered public accounting firm, PricewaterhouseCoopers LLP, has issued an audit report on the Company’s internal control over financial reporting. See “Report of Independent Registered Public Accounting Firm” in Part II, Item 8 of this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting
