EXPLANATORY NOTE

On May 17, 2021, Assertio Holdings, Inc. (the “Company”) filed a Current Report on Form 8-K (the “Initial 8-K”) to report the voting results for all proposals (other than Proposals 2 and 3) brought before the Company’s previously adjourned 2021 Annual Meeting of Stockholders held virtually on May 11, 2021 (the “Annual Meeting”). This Amendment No. 1 amends the Initial 8-K to disclose the voting results with respect to Proposals 2 and 3 described under Item 5.07 below.

On June 9, 2021, the Company resumed the Annual Meeting, which had been previously adjourned with respect to Proposals 2 and 3. The results of the stockholder votes on Proposals 2 and 3 brought before the Annual Meeting were as follows:

Proposal 2: To approve an amendment to the Company’s certificate of incorporation to effect a reverse stock split and proportionally reduce the number of authorized shares of common stock. The votes on Proposal 2 were as follows:

Proposal 3: To approve an amendment to the Company’s certificate of incorporation to increase the number of authorized shares of common stock from 200,000,000 to 300,000,000 shares. The votes on Proposal 3 were as follows:

Accordingly, Proposals 2 and 3 were not approved because the votes “For” each of the proposals represented less than a majority of the Company’s outstanding shares of common stock as of the record date for the Annual Meeting.
