| 6. | Stockholders’ Equity
Our common stock outstanding as of September 30, 2023 and December 31, 2022 was 15,016,295 shares. Annual Meeting of Stockholders In June 2023, our stockholders approved an amendment to the 2015 Omnibus Equity Incentive plan to increase the number of authorized shares to 2,500,000 shares. September 2023 Preferred Stock In September 2023, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with The Sire Group Ltd. (“Sire Group” or the “Investor”), pursuant to which we agreed to issue 950,000 shares of Series AA Convertible Preferred Stock, par value $0.001 per share (the “Series AA Preferred Stock”) to the Investor at a price of $10.00 per share, for an aggregate purchase price of $9.5 million (the “Private Placement”). The purchase price consisted of (i) $5.0 million in cash at closing and (ii) $4.5 million in the form of a promissory note from Sire Group which was paid off in September 2023. Each share of Series AA Preferred Stock will be convertible, at the holder’s option at any time, into shares of our common stock at a conversion rate equal to the quotient of (i) the stated value of such share divided by (ii) the initial conversion price of $0.466, subject to specified adjustments as set forth in the Certificate of Designations. The Series AA Preferred Stock contains limitations that prevent the Investor from acquiring the lower of either (i) the maximum percentage of common stock permissible under the rules and regulations of The Nasdaq Stock Market (“Nasdaq”) without first obtaining shareholder approval or (ii) 19.99% of our outstanding common stock. The holder of the Series AA Preferred Stock is entitled to receive dividends on shares of the Series AA Preferred Stock equal (on an as-if-converted-to-common-stock basis) to and in the same form as dividends actually paid on shares of the common stock. No other dividends will be paid on shares of the Series AA Preferred Stock. Any shares of Series AA Preferred Stock may, at the option of the holder, be converted at any time into that number of shares of common stock at the conversion price set forth above. Without approval of holders of a majority of the outstanding Series AA Preferred Stock, we may not (a) alter or adversely change the powers, preferences or rights given to the Series AA Preferred Stock, (b) amend its certificate of incorporation or other charter documents in any manner that adversely affects any rights of the holders of the Series AA Preferred Stock, (c) increase the number of authorized shares of the Series AA Preferred Stock, (d) enter into or consummate any Fundamental Transaction (as defined in the Certificate of Designations), or (e) enter into any agreement with respect to any of the foregoing. In the event of any liquidation, dissolution or winding up, the holder of the Series AA Preferred Stock will be entitled to receive out of the assets, whether capital or surplus, the same amount that a holder of common stock would receive if the Series AA Preferred Stock were fully converted to common stock, which amounts shall be paid pari passu with all holders of common stock. February 2022 Offerings In February 2022, we completed a registered direct offering with an accredited investor pursuant to which we issued an aggregate of 1,100,000 shares of our common stock and 2,274,242 pre-funded warrants to purchase shares of our common stock, with an exercise price of $0.001 per share. In a concurrent private placement, we sold unregistered pre-funded warrants to purchase an aggregate of 1,289,796 shares of common stock with an exercise price of $0.001 per share and issued unregistered five year and six month warrants to purchase an aggregate of 4,664,038 shares of common stock with an exercise price of $1.14. The net cash proceeds from these offerings were approximately $5.0 million after deduction of underwriting fees and other offering expenses. Warrant Exercises In March 2022, we received approximately $1,000 from the exercise of 974,242 pre-funded warrants issued in the February 2022 registered direct offering. JT Pharma Milestone In January 2022, we entered into an agreement with JT Pharma to clarify certain provisions of the JT Agreement pursuant to which we agreed that the proof-of-concept milestone provided for in the JT Agreement was achieved and made a payment of $100,000 and issued 51,021 shares of our common stock to JT Pharma. Restricted Shares In August 2021, we agreed to issue 50,000 shares of our common stock pursuant to a restricted stock agreement with Maxim Partners, LLC in connection with the entry into an amendment to our existing advisory agreement. The shares vested monthly over 12 months. We recorded approximately $27,000 and $54,000 of stock-based compensation expense during the three and nine months ended September 30, 2022, respectively.
