(“GPGI”) and the parent of our managed company, GPGI Holdings, L.L.C. (f/k/a CompoSecure Holdings, L.L.C.) (“GPGI Holdings”), together with certain of its subsidiaries, completed its previously announced combination with Husky Technologies Limited (“Husky,” and the combination therewith, the “Husky Combination”).

On January 13, 2026, the Company filed a Current Report on Form 8-K reporting the Husky Combination and related matters (the “Original Report”), which included disclosure under Item 2.01 of Form 8-K and related financial statements under Item 9.01(b) of Form 8-K, due to the requirement of the Company’s current accounting presentation that the Company’s financial statements consolidate the results of GPGI Holdings. Accordingly, this Current Report on Form 8-K/A amends the Original Report to provide the pro forma financial information required under Item 9.01(b) of Form 8-K. The historical financial information of Husky required under Item 9.01(a) was previously filed on March 12, 2026 with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025. Except as set forth herein, this Amendment No. 1 does not amend, modify or update the disclosure contained in the Original Report (including the exhibits thereto).

The historical financial information of Husky required under Item 9.01(a) was previously filed on March 12, 2026 as Exhibit 99.1 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

The unaudited pro forma consolidated financial information of the Company and Husky at and for the fiscal year ended December 31, 2025, and the notes related thereto, is filed as Exhibit 99.1 to this Amendment No. 1 and incorporated by reference herein.

The unaudited pro forma consolidated financial information has been presented for informational purposes only, as required by Form 8-K, and does not purport to represent the actual results of operations that the Company and Husky would have achieved had GPGI and Husky combined at and during the periods presented in the unaudited pro forma consolidated financial information, and is not intended to project the future results of operations that the combined company may achieve following the Husky Combination.
