Item 1.02. Termination of a Material Definitive Agreement.

 

On August 27, 2025, ProPhase Labs, Inc. (the “Company”) delivered notice to Keystone Capital Partners, LLC (“Keystone”) to terminate, effective the next trading day, the Common Stock Purchase Agreement dated January 29, 2025, between the Company and Keystone (the “Keystone Agreement”). Pursuant to such notice, the Keystone Agreement terminated effectively on Thursday, August 28, 2025.

 

The Keystone Agreement established an equity line of credit facility under which the Company had the right, but not the obligation, to sell shares of its common stock to Keystone up to an aggregate purchase price of approximately $7.7 million. The Keystone Agreement provided that the Company could terminate the facility at any time, in its sole discretion, upon one trading day’s prior written notice, without cost or penalty. The Company terminated the Keystone Agreement in its sole discretion and incurred no penalties or termination fees in connection with the termination. Other than the Keystone Agreement, there are no material relationships between the Company or its affiliates and Keystone.
