Proposals One, Three, and Four Pass; Meeting Adjourned with respect to Proposal Two

Stockholders who have not voted on Proposal Two are strongly encouraged to vote their shares

Meeting to reconvene on January 14, 2022

NovaBay^® Pharmaceuticals, Inc. (NYSE American: NBY) (“NovaBay” or the “Company”) announces that its Special Meeting of Stockholders held on December 17, 2021 has been adjourned until January 14, 2022 at 11:00 a.m. Pacific time in order to provide stockholders additional time to vote on Proposal Two, which is a proposal to approve an amendment to the NovaBay Amended and Restated Certificate of Incorporation to effect an increase in authorized common stock from 100,000,000 shares to 150,000,000 shares.

Proposal Two has received significant support based on the shares that have been voted by stockholders. As of the Special Meeting of Stockholders, approximately 83.5% of the shares that had been voted on Proposal Two were voted in its favor. However, the favorable votes were less than 50% of all outstanding shares of common stock, which is the minimum threshold required to approve this proposal. The Board of Directors continues to believe that the approval of Proposal Two is in the best interests of NovaBay and its stockholders, and one of the leading independent proxy voting advisory groups, Institutional Shareholder Services (“ISS"), recommended that stockholders vote FOR Proposal Two. All other proposals presented for consideration at the Special Meeting of Stockholders only required a majority of the votes present in person or by proxy as long as a quorum was present and all such other proposals passed on December 17, 2021.

The Board of Directors and management requests that these stockholders consider and vote their proxies as soon as possible on Proposal Two, but no later than January 13, 2022 at 11:59 p.m. Eastern time. Stockholders who have previously submitted their proxy or otherwise voted on Proposal Two at the Special Meeting of Stockholders and who do not want to change their vote need not take any action.
