EXPLANATORY NOTE

This Form 8-K/A amends the Current Report on Form 8-K filed by CompoSecure, Inc. on June 11, 2025 (the “Original Report”). This amendment is being filed solely for the purpose of including the required XBRL tagging on the cover page, which was inadvertently excluded from the Original Report. Except for the foregoing, this amendment does not modify or update any disclosure contained in the Original Report or its exhibits.

On June 10, 2025, Timothy Fitzsimmons, Chief Financial Officer (“CFO”) of CompoSecure, Inc. (the “Company”) informed the Company’s Board of Directors that he will retire from his position as of the date the Company names a successor CFO and such successor assumes the role, which is anticipated to occur in the second half of 2025, but no later than January 1, 2026 (the “Transition Date”). Mr. Fitzsimmons’ advance notice of his retirement allows lead time for the Company to conduct a comprehensive search for his replacement and for Mr. Fitzsimmons to assist with the orderly transition of duties to his successor.

Following his retirement as CFO, Mr. Fitzsimmons will serve as a consultant to the Company through January 1, 2027, and has entered into a Transition and Consulting Agreement, dated June 10, 2025, regarding the same to ensure an orderly transition to his successor. Provided Mr. Fitzsimmons remains employed with the Company through the Transition Date, he will continue to receive his base salary and employee benefits and will remain eligible to receive an incentive payment for 2025, in an amount depending on actual Company performance. In addition, if Mr. Fitzsimmons remains employed by or in the service of the Company through January 1, 2026 (or upon his earlier death or disability), he will also remain eligible for vesting of restricted stock units and performance-based restricted stock units that are scheduled to vest on January 1, 2026. From the period commencing on the Transition Date through January 1, 2027 (the “Consulting Term”), Mr. Fitzsimmons will be eligible to continue medical coverage for himself and his dependents through the Consolidated Omnibus Reconciliation Act of 1985 (“COBRA”) at the Company’s expense and, provided he remains a consultant through the end of the Consulting Term (or upon his earlier death or disability), Mr. Fitzsimmons will remain eligible for vesting of restricted stock units and performance-based restricted stock units that are scheduled to vest on January 1, 2027. Mr. Fitzsimmons will also remain subject to restrictive covenants and provide the Company with a general release of claims.

The foregoing summary of the Transition and Consulting Agreement does not purport to be complete, and is qualified in its entirety by the full text of the Transition and Consulting Agreement, a copy of which is expected to be filed as an exhibit to the Company’s next quarterly report on Form 10-Q.

On June 11, 2025, the Company issued a press release announcing the matters set forth under Item 5.02 above.

The information set forth in Item 7.01, including Exhibit 99.1, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section.
