The combined public offering price for each share of common stock (or pre-funded warrant in lieu thereof) and accompanying Series F-1 warrant, Series F-2 warrant and Series F-3 warrant is $1.10.

In addition, the Company has granted the underwriter for the offering a 45-day option to purchase up to 477,272 additional shares of common stock and/or up to 477,272 Series F-1 warrants to purchase up to 477,272 shares of common stock, up to 477,272 Series F-2 warrants to purchase up to 477,272 shares of common stock and up to 477,272 Series F-3 warrants to purchase up to 477,272 shares of common stock or any combination thereof, as determined by the underwriter, at the public offering price, less underwriting discounts and commissions, in each case solely to cover over-allotments, if any.

Ladenburg Thalmann & Co. Inc. is acting as sole bookrunning manager for the offering.

Each share of common stock (and each pre-funded warrant in lieu thereof) is being sold together with one Series F-1 warrant to purchase one share of common stock, one Series F-2 warrant to purchase one share of common stock, and one Series F-3 warrant to purchase one share of common stock. The Series F-1 warrants have an exercise price of $1.10 per share, are exercisable immediately upon issuance, and will expire five years following the date of issuance. The Series F-2 warrants have an exercise price of $1.10 per share, are exercisable immediately upon issuance, and will expire six months following the date of issuance. The Series F-3 warrants have an exercise price of $1.10 per share, are exercisable immediately upon issuance, and will expire one year following the date of issuance. The pre-funded warrants will be immediately exercisable at a nominal exercise price of $0.01 per share and may be exercised at any time until all of the pre-funded warrants are exercised in full. The Series F-1 warrants, the Series F-2 warrants and the Series F-3 warrants will each include a one-time reset of the exercise price to a price equal to the lesser of (i) the then exercise price and (ii) 90% of the five-day volume weighted average prices for the five (5) trading days immediately preceding the date that is sixty calendar days after issuance of the Series F-1 warrants, the Series F-2 warrants and the Series F-3 warrants, as applicable.

The aggregate gross proceeds from the offering will be approximately $3.5 million, or $4.0 million if the underwriter exercises its over-allotment option in full, before deducting underwriting discounts and commissions and other offering expenses and excluding any proceeds that may be received upon the exercise of the Series F-1 warrants, Series F-2 warrants, and Series F-3 warrants. No assurance can be given that any of the warrants will be exercised. NovaBay currently intends to use the net proceeds of the offering to redeem the outstanding principal amount of its Original Discount Senior Secured Convertible Debentures due November 1, 2024 and for working capital and general corporate purposes.

The offering is expected to close on or about July 29, 2024, subject to the satisfaction of customary closing conditions.
