CACI International Changes Fiscal Year End to December 31 and Amends By-Laws

Overview of Filing

On October 21, 2026, CACI International Inc ($CACI) filed a Form 8-K under Item 5.03 (Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year) and Item 9.01 (Financial Statements and Exhibits), detailing corporate governance actions approved by its Board of Directors on October 20, 2026.

Key Changes

1. Fiscal Year-End Change:

   • The Board approved shifting the Company's fiscal year end from June 30 to December 31, aligning reporting with standard calendar quarters.
   • The Company will utilize a transition period running from July 1, 2026 through December 31, 2026, and plans to file a transition report on Form 10-KT for this stub period.

2. By-Law Amendments:

   • Board Discretion over Fiscal Year: By-laws amended to stipulate that the fiscal year is fixed and changeable directly by the Board.
   • Annual Meeting Date Flexibility: Removed the rigid date requirement (previously the third Friday of October) in favor of allowing the Board to designate the date, time, and location.
   • Advance Notice Window: Standardized shareholder proposal and director nomination submission windows to 90 to 120 days prior to the first anniversary of the preceding annual meeting.
   • Alternative Notice Provisions: Updated mechanics for situations where the annual meeting date shifts by more than 30 days earlier or 60 days later than the previous year's anniversary.

Market & Trading Significance

• Trading Significance: Low. The updates represent standard administrative and governance house-keeping. Shifting to a calendar-year fiscal cycle simplifies quarterly comparisons against peer defense and IT services contractors, but does not impact fundamental business operations or cash flow.
