Explanatory Note
On May 12, 2026, Collegium Pharmaceutical, Inc. (the “Company”) filed a Current Report on Form 8-K with the Securities and Exchange Commission (the “Original Form 8-K”), reporting among other items, that the Company completed the previously announced acquisition (the “Closing”) of (i) all of the issued and outstanding limited liability interests of GPC Commave Holding, LLC, a Delaware limited liability company (“GPC”), from Corium Therapeutics Holdings, LLC, a Delaware limited liability company (“Corium” or “Commave Seller”), and (ii) all of the issued and outstanding limited liability interests of Commave Sub, LLC, a Delaware limited liability company, from Corium, LLC, a Delaware limited liability company (“Corium Seller” and together with Commave Seller, the “Seller Parties”), pursuant to an Equity Purchase Agreement (the “Purchase Agreement”), by and among the Company and Seller Parties, dated March 19, 2026. Upon the Closing, the Company acquired AZSTARYS®, a central nervous system stimulant prescription medicine used for the treatment of Attention-Deficit/Hyperactivity Disorder, in people 6 years of age and older (the “Acquisition”).
The aggregate consideration paid by the Company at the Closing pursuant to the Purchase Agreement was approximately $655.6 million in cash (following customary adjustments for net working capital, indebtedness, cash, and transaction expenses), which was funded by approximately $355.6 million of the Company’s existing cash on hand and $300.0 million from a delayed draw term loan which is part of the Credit Agreement the Company entered into in December 2025. The Company may also pay Commave Seller up to $135 million in additional consideration if AZSTARYS achieves certain future commercial and manufacturing milestones.
The Company is filing this amendment to the Original 8-K (this “Form 8-K/A”) to amend and supplement the Original 8-K to include historical financial statements of Corium and pro forma financial information as required by Items 9.01(a) and 9.01(b), respectively, of Form 8-K that were excluded from the Original 8-K in reliance on the instructions to such items. Except as noted in this paragraph, no other information contained in the Original 8-K is amended or supplemented. This Form 8-K/A should be read together with the Original 8-K.
The historical financial statements of Corium included under Item 9.01(a) are on a consolidated basis, which includes both AZSTARYS and ADLARITY®, an FDA-approved Alzheimer’s product that was not part of the Acquisition and is no longer actively commercialized by the Seller Parties. The Company did not acquire ADLARITY. AZSTARYS constituted substantially all of Corium’s consolidated operations, and accordingly Corium’s consolidated financial statements are presented pursuant to Rule 3-05 of Regulation S-X.
The unaudited pro forma financial information included in Item 9.01(b) reflects the acquisition of AZSTARYS only. The results, assets, and liabilities of ADLARITY have been excluded from the pro forma financial information, as further described in the notes thereto.
