Note 16 - Warrants

Liability Classified Warrants

On June 8, 2023, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) pursuant to which the Company issued and sold an aggregate of (i) 1,743,695 shares of the Company’s common stock; (ii) pre-funded warrants in lieu of shares to purchase 430,217 shares of common stock; (iii) accompanying Tranche A Warrants to purchase 2,173,912 shares of common stock; and (iv) accompanying Tranche B Warrants to purchase 2,173,912 shares of common stock in a best-efforts offering. The Tranche A Warrants and Tranche B Warrants may be exercised for either shares of common stock or pre-funded exchange warrants to purchase common stock at a future exercise price of $0.0001 per share in the same form as the pre-funded warrant. Each pre-funded warrant is exercisable for one share of common stock at an exercise price of $0.0001 per share. The pre-funded warrants are immediately exercisable and may be exercised at any time until all of the pre-funded warrants are exercised in full. The Tranche A Warrants and Tranche B Warrants are immediately exercisable at a price of $1.59 per share (or $1.5899 per pre-funded exchange warrant). The Tranche A Warrants will expire upon the earlier of (i) five years after the date of issuance or (ii) 30 days following the closing price of the Company’s common stock equaling 200% of the exercise price ($3.18 per share) for at least 40 consecutive trading days. The Tranche B Warrants will expire upon the earlier of (i) five years after the date of issuance or (ii) 30 days following the Company’s achievement of consolidated trailing twelve-month adjusted EBITDA (as defined in the Securities Purchase Agreement) of $12 million (see Note 14 – Capital Structure).

On August 11, 2022, the Company closed an offering (the “August 2022 Offering”), pursuant to which, the Company issued pre-funded warrants to purchase 87,500 shares of its common stock and common warrants to purchase 1,265,547 shares of its common stock. The shares of common stock and the pre-funded warrants were each sold in combination with corresponding common warrants, which one common warrant to purchase one share of common stock for each share of common stock or each pre-funded warrant was sold. The pre-funded warrants had an exercise price of $0.02 per share of common stock and were exercised in full in August 2022. The common warrants have an exercise price of $8.60 per share of common stock and are exercisable for a period of five years from issuance. The common warrants provide that if there occurs any stock split, stock dividend stock recapitalization, or similar event (a “Stock Combination Event”), then the warrant exercise price will be adjusted to the greater of the quotient determined by dividing the sum of the VWAP of the common stock for each of the five lowest trading days during the 20 consecutive trading day period ending immediately preceding the 16th trading day after such Stock Combination Event, divided by five; or $2.32, and the number of shares of common stock to be issued would be adjusted proportionately as set forth in the agreement limited to a maximum of 2,325,581 shares. The common warrants also provide that in the event the Company were to engage in an equity offering at a common stock price lower than the warrant exercise price prior to the second anniversary of a Stock Combination Event, the exercise price would be adjusted to the greater of the effective price of such equity offering or $2.32 (see Note 14 – Capital Structure).

In November 2022 and throughout the quarter ended December 31, 2022, the Company sold shares through its ATM Sales Agreement. Per the warrant agreement in the August 2022 Offering, these sales qualified as an equity offering, and the sales price was less than the current exercise price of $8.60. As a result, the common warrants exercise price was adjusted to $3.30. On January 6, 2023, the Company consummated a 20 to 1 reverse stock split. Pursuant to the warrant agreement described above, the Company triggered a Stock Combination Event, and the warrant exercise price and number to be issued was adjusted based on the average of each of the lowest five trading days during the twenty-day consecutive trading day period beginning on December 30, 2022. Subsequently, as a result of the Securities Purchase Agreement in June 2023, the common warrants from the August 2022 Offering had an adjusted exercise price of $2.32.

Certain outstanding warrants are classified as derivative warrant liabilities in the consolidated balance sheets and are marked to market at each reporting period (see Note 12 – Fair Value Considerations).
