Item 5.07. Submission of Matters to a Vote of Security Holders.

Effective November 3, 2022, the holders of a majority of the voting power of the capital stock of Checkpoint Therapeutics, Inc. (the “Company”) executed a written consent approving a grant of discretionary authority to the board of directors of the Company (the “Board”) to, without further stockholder approval, (i) effect a 1:10 reverse stock split of the Company’s issued and outstanding common stock (the “Reverse Stock Split”), (ii) effect a related reduction in the number of the Company’s authorized shares by filing an amendment (the “Certificate Amendment”) to the Company’s Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, and (iii) effect an amendment to the Company’s Amended and Restated 2015 Incentive Plan to increase the number of shares issuable thereunder, after giving effect to the Reverse Stock Split, from 900,000 to 3,000,000 (the “Plan Amendment”). The written consent was signed by the holders of 10,914,552 shares of the Company’s common stock and 7,000,000 shares of the Company’s Class A Common Stock. Each share of common stock entitles the holder thereof to one vote on all matters submitted to stockholders and each share of Class A Common Stock has the voting power of 1.1 times a fraction, the numerator of which is the sum of the shares of outstanding common stock and the denominator of which is the number of shares of outstanding Class A Common Stock, or approximately 13.5 votes per share as of November 3, 2022. Accordingly, the holders of approximately 58% of the voting power of the Company’s capital stock as of November 3, 2022, signed the written consent approving the Reverse Stock Split, the Certificate Amendment, and the Plan Amendment. The Board also approved the Reverse Stock Split, the Certificate Amendment, and the Plan Amendment.

Pursuant to rules adopted by the Securities and Exchange Commission under the Securities Exchange Act of 1934, a Schedule 14C information statement will be filed with the Securities and Exchange Commission and sent or provided to the stockholders of the Company.
