---

On March 12, 2026, CACI International Inc ("CACI"), the subsidiary guarantors named therein (the "Guarantors") and U.S. Bank Trust Company, National Association, as trustee (the "Trustee"), entered into a second supplemental indenture (the "Second Supplemental Indenture") to the indenture, dated as of June 2, 2025 (the "Base Indenture"), as supplemented by that first supplemental indenture (the "First Supplemental Indenture"), dated as of November 25, 2025 (the Base Indenture, as supplemented by the First Supplemental Indenture and the Second Supplemental Indenture, the "Indenture"), pursuant to which CACI issued (the "Offering") $500 million aggregate principal amount of CACI's unsecured Senior Notes due 2033 (the "Additional Notes"), which were issued as part of the same series as CACI's 6.375% Senior Notes due 2033 originally issued in June 2025 (the "Original Notes" and, together with the Additional Notes, the "Notes"). The Notes are unconditionally guaranteed on a senior unsecured basis by the Guarantors. Upon completion of the Offering, the total aggregate principal amount of Notes outstanding is $1,500,000,000.

CACI sold the Additional Notes to the initial purchasers (the "Initial Purchasers") in a private placement to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. CACI received net proceeds from the Offering of approximately $518 million. CACI intends to use the net proceeds from the Offering to repay certain indebtedness under its revolving credit facility that was incurred to pay a portion of the purchase price of its acquisition of ARKA Group L.P. and costs and expenses related thereto.

The Notes are senior unsecured obligations of CACI and are guaranteed fully, unconditionally and jointly and severally, on a senior unsecured basis, by each of the Guarantors. The Notes bear interest at the rate of 6.375% per annum, payable semi-annually in arrears on June 15 and December 15 of each year. The first interest payment for the Additional Notes will be June 15, 2026, and will include accrued and unpaid interest from December 15, 2025 (the most recent interest payment date for the Notes). The Notes mature on June 15, 2033, unless earlier repurchased or redeemed. The Indenture contains customary covenants and events of default, which include, among other things, failure to make required payments, failure to make a Change of Control Offer (as such term is defined in the Indenture) within the required time, failure to comply with certain agreements or covenants, failure to pay or acceleration of certain other indebtedness, a guarantee being held unenforceable or invalid, certain events of bankruptcy and insolvency, and failure to pay certain judgments. An event of default under the Indenture will allow either the Trustee or the holders of at least 30% in aggregate principal amount of the then-outstanding Notes to accelerate the amounts due under the Notes.

The foregoing description of the Indenture and the Additional Notes does not purport to be complete and is qualified in its entirety by reference to the full text of the Base Indenture, the First Supplemental Indenture, the Second Supplemental Indenture and the form of 6.375% Senior Notes due 2033, which are filed as Exhibit 4.1, Exhibit 4.2, Exhibit 4.3 and Exhibit 4.4 respectively, to this Current Report on Form 8-K and are incorporated herein by reference.
