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

On May 3, 2016, NovaBay held its 2016 Annual Meeting, at which the Company’s stockholders considered four (4) proposals, each of which is described in more detail in the Company’s proxy statement filed with the Securities and Exchange Commission on April 18, 2016 (the “Proxy Statement”). There were 5,074,806 outstanding shares entitled to vote and there were 2,756,645 shares present in person or by proxy at the 2016 Annual Meeting, representing fifty-four percent (54%) of the shares outstanding and entitled to vote. Proposals 1, 2 and 4 were approved, while Proposal 3 below regarding the compensation of NovaBay’s named executive officers failed to receive enough affirmative votes for approval. The voting results are presented below.

1.     To elect the three (3) Class III directors named below to hold office until the 2019 Annual Meeting, or until their successors have been duly elected and qualified.

2.     To approve the issuance of shares of NovaBay common stock and warrants to purchase common stock to purchasers pursuant to the terms of the Securities Purchase Agreement, dated April 4, 2016, in accordance with the stockholder approval requirements of NYSE MKT Company Guide Sections 713 and 711.

3.     To approve, on an advisory basis, the compensation of NovaBay’s named executive officers, as disclosed in the Proxy Statement.

¹       A broker non-vote occurs when a broker, bank or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to the item and has not received voting instructions from the beneficial owner of the shares it holds. Broker non-votes are counted when determining whether the necessary quorum of stockholders is present or represented at each annual meeting.

4.     To ratify the appointment by NovaBay’s Audit Committee of OUM & Co. LLP as NovaBay’s independent registered public accounting firm for the fiscal year ending December 31, 2016.

In connection with the Annual Meeting, the Company also solicited proxies with respect to a proposal to approve an amendment to the NovaBay Pharmaceuticals, Inc. 2007 Omnibus Incentive Plan, as amended, to increase the number of shares of NovaBay common stock reserved for issuance thereunder by two million five hundred thousand (2,500,000) shares (the “2007 Plan Proposal”). At the time of the 2016 Annual Meeting, there were an insufficient number of votes needed to approve the 2007 Plan Proposal. Given the important nature of the 2007 Plan Proposal, the Company decided to adjourn the 2016 Annual Meeting to allow additional time for stockholders to consider this proposal, and for the Company to solicit additional proxies on the matter. As such, the presiding Chairman of the 2016 Annual Meeting adjourned the meeting, which will reconvene at 3 p.m. Pacific time on Thursday, May 26, 2016, at 5858 Horton Street, Suite 260, Emeryville, California 94608 for the purpose of holding a stockholder vote on the 2007 Plan Proposal. During the period of adjournment, the Company will continue to accept stockholder votes on such proposal.
