Effective July 25, 2022, the holders of a majority of the voting power of the capital stock of Avenue 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 reverse stock split of the Company’s issued and outstanding common stock within a range of between 10-for-1 and 20-for-1 (with the Board being authorized to determinate the exact ratio) (the “Reverse Stock Split”) and (ii) effect a related reduction in the number of the Company’s authorized shares (the “Authorized Share Reduction”) by filing an amendment (the “Amendment”) to the Company’s Third Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware. The written consent was signed by the holders of 9,423,429 shares of the Company’s common stock and 250,000 shares of the Company’s Class A Preferred 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 Preferred Stock has the voting power of 1.1 times (A) the number of outstanding shares of common stock plus (B) the whole shares of Company common stock into which the outstanding shares of Class A Preferred Stock are convertible, divided by the number of outstanding shares of Class A Preferred Stock, or 99 votes per share as of July 25, 2022. Accordingly, the holders of approximately 73% of the voting power of the Company’s capital stock as of July 25, 2022 signed the written consent approving the Reverse Stock Split, the Authorized Share Reduction and the Amendment. The Board also approved the Reverse Stock Split, the Authorized Share Reduction and the 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.
