February 2023 Public Offering of Common Stock and Warrants On February 8, 2023, the Company closed a public offering of 21,983 units, with each consisting of one share of its common stock, or one pre-funded warrant to purchase one share of its common stock, and one warrant to purchase -half shares of its common stock. Each unit was sold at the public offering price of $464.00. The warrants in the units are immediately exercisable at a price of $464.00 per share and expire five years from the date of issuance. Alternatively, each warrant can be exercised pursuant to the “alternative cashless exercise” provision, to which the holders would receive an aggregate number of shares of common stock equal the product of (x) the aggregate number of shares of common stock that would be issuable upon a cash exercise and (y) 0.50. For purposes of clarity, one common warrant to purchase -half shares would be exercisable for 0.75 shares under this alternative cashless exercise provision. The shares of common stock (or pre-funded warrants in lieu thereof) and accompanying warrants were only purchasable together in this offering but were issued separately and immediately separable upon issuance. As of September 30, 2024 warrants to purchase 28,869 shares of common stock have been exercised under the alternative cashless exercise for a total of 14,402 shares of common stock. Net proceeds, after deducting underwriting discounts and commissions and estimated offering expenses, were approximately $10.2 million. The Company has been using the net proceeds of this offering to continue implementation of its growth strategies, for working capital and general corporate purposes. The Company also granted the underwriters an option to purchase an additional 3,298 shares of common stock and/or additional warrants to purchase up to 4,947 shares of common stock, to cover over-allotments, of which Maxim Group LLC exercised its option to purchase additional warrants to purchase 4,947 shares of common stock. |
The Company may issue preferred stock, common stock, or both, in connection with underwritten public offerings, registered direct offerings, private placements or business acquisitions. Such issuances of equity typically include the issuance or sale of warrants to purchase common stock. Certain issuances of convertible preferred stock and warrants may contain anti-dilutive features apart from customary adjustments for splits and reverse splits of common stock (collectively, “down round features”). When a series of convertible preferred stock contains this non-standard down round feature, the Company is required to adjust the conversion price in the event of future stock sales at a lower unit price. When warrants issued in connection with an equity transaction contain, or are amended to contain, this non-standard down round feature, the Company is required to adjust the exercise price upon the issuance of any shares of common stock or securities convertible into shares of common stock below the then-existing exercise price and evaluate and account for the value attributable to the reduced warrant exercise price. In the event down round adjustments are triggered, the values attributable to the adjustment to the convertible preferred stock conversion price and warrant exercise price are recorded as an increase to additional paid-in capital and increase to accumulated deficit. All series of the Company’s convertible preferred stock are classified in stockholders’ equity, including those with the down round feature, when applicable to the equity transaction. Warrants to purchase common stock are classified in stockholders’ equity, including those issued with the down round feature, as they are both indexed to the Company’s own stock and meet the scope exception in ASC 815 “Derivatives and Hedging.” The Company had the following equity transactions during the years ended December 31, 2023 and 2022: November 2023 Exercise of Warrants for Common Stock On November 21, 2023, the Company entered into a warrant exercise agreement with an existing accredited investor to exercise certain outstanding warrants to purchase up to an aggregate of 92,802 shares of the Company’s common stock (the “Existing Warrants”). In consideration for the immediate exercise of the Existing Warrants for cash, the exercising holders received new unregistered warrants to purchase up to an aggregate of 185,604 shares (equal to 200% of the shares of common stock issued in connection with the Exercise) of the Company’s common stock (the “New Warrants”) in a private placement. In connection with the Exercise, the Company also agreed to reduce the exercise price of the Existing Warrants from $14.52 to $13.34 and to reduce the exercise price of the remaining unexercised warrants from either $19.14 or $14.52 to $13.34 per share, which is equal to the most recent closing price of the Company’s common stock on The Nasdaq Capital Market prior to the execution of the warrant exercise agreement. The New Warrants will become exercisable six months after issuance at an exercise price of $13.34 per share and have a term of exercise equal to and one-half years. The Existing Warrants and the New Warrants each include a beneficial ownership limitation that prevents the investor from owning more than 9.99%, with respect to the Existing Warrants, and 4.99%, with respect to the New Warrants, of the Company’s outstanding common stock at any time. The gross proceeds to the Company from the Exercise was approximately $1.2 million, prior to deducting warrant inducement agent fees and estimated offering expenses.
