Warrant Expiration Effective February 26, 2023, a warrant to purchase 125,000 shares of common stock expired unexercised. Equity Capital Raises On February 17, 2023, the Company entered into an underwriting agreement with Newbridge Securities Corporation (“Newbridge”) in connection with an underwritten public offering of 4,945,000 shares of the Company’s common stock, which includes Newbridge’s exercise in full of its overallotment option, pursuant to the Company’s “shelf” registration statement on Form S-3 (declared effective by the SEC on November 8, 2021, File No. 333-259783) (as amended and supplemented from time to time, the “2021 Form S-3”). The public offering price was $1.75 per share. The underwriter purchased the shares from the Company at a price of $1.6275 per share on February 22, 2023, after taking into account the underwriting discounts and commissions. The net proceeds received by the Company for the sale and issuance of the shares were approximately $8.0 million, before deducting offering expenses of $0.2 million paid by the Company. On June 1, 2023, the Company entered into an underwriting agreement with Prime Executions, Inc. dba Freedom Capital Markets (“Freedom”) acting as the book-running manager of the offering and Bancroft Capital, LLC acting as co-manager in connection with an underwritten public offering of 14,950,000 shares of the Company’s common stock, which includes Freedom’s exercise in full of its overallotment option, pursuant to the 2021 Form S-3. The underwriter purchased 13,000,000 shares and 1,950,000 shares from the Company on June 5 and June 23, 2023 respectively. The public offering price was $1.27 per share. The underwriter purchased the shares from the Company at a price of $1.1811 per share. The net proceeds received by the Company for the sale and issuance of the shares were approximately $17.6 million, before deducting offering expenses of $0.1 million paid by the Company. In addition, the Company issued warrants to purchase an aggregate of 448,500 shares of Company common stock to Freedom, at an exercise price of $2.00 per share. The Company evaluated the warrants as either equity-classified or liability-classified instruments based on an assessment of the specific terms of the warrants and applicable authoritative guidance in ASC 480 and ASC 815-40. The Company determined the warrants issued in the Freedom offering failed the indexation guidance under ASC 815-40, specifically, the warrants provide for a Black-Scholes value calculation in the event of certain transactions (“Fundamental Transactions”), which includes a floor on volatility utilized in the value calculation at 100% or greater. The Company has determined that this provision introduces leverage to the holders of the warrants that could result in a value that would be greater than the settlement amount of a fixed-for-fixed option on the Company’s own equity shares. Accordingly, pursuant to ASC 815-40, the Company has classified the fair value of the warrants as a liability upon issuance and marked to market each reporting period in the Company’s consolidated statement of operations until their exercise or expiration. The fair value of the warrants as of June 1, 2023, the issuance date, and September 30, 2023, were $366,960 and $117,115, respectively. The warrant liability was estimated using the Black-Scholes pricing model with the following assumptions.
|  |  |  |  | (At Issuance) |
|  | September 30, 2023 |  |  | June 1, 2023 |
Risk-free interest rate |  |  | 4.6 | % |  |  | 3.7 | %
Expected volatility |  |  | 72.34 | % |  |  | 71.56 | %
Expected life (years) |  |  | 4.72 |  |  |  | 5.03 |
Expected dividend yield |  |  | - |  |  |  | - |
Total fair value |  | $ | 117,115 |  |  | $ | 366,960 |
The fair value of the warrants deemed to be a liability, due to certain contingent put features, was determined using the Black-Scholes option pricing model, which was deemed to be an appropriate model due to the terms of the warrants issued, including a fixed term and exercise price. Equity Distribution Agreement On May 20, 2022, the Company entered into an equity distribution agreement (the “2022 EDA”) with Jefferies LLC (“Jefferies”) to sell shares of the Company’s common stock, with an aggregate offering price of up to $25.0 million, from time to time through an “at the market” offering pursuant to the Company’s 2021 Form S-3 through Jefferies acting as the Company’s agent and/or principal. The Company is not obligated to sell any shares under the 2022 EDA. During the three months ended September 30, 2023, the Company did not sell any shares of its common stock under the 2022 EDA. During the nine months ended September 30, 2023, the Company raised aggregate net proceeds (net of broker commissions and fees) of approximately $0.7 million under the 2022 EDA through the sale of 279,703 shares of its common stock. As of September 30, 2023, the Company has raised aggregate net proceeds (net of broker commissions and fees) of approximately $1.5 million under the 2022 EDA through the sale of 630,532 shares of its common stock.
