10. 2021 REGISTERED DIRECT OFFERING
On February 11, 2021, the Company entered into a Securities Purchase Agreement (the “2021 SPA”) with certain institutional and accredited investors (collectively, “2021 Investors”) providing for the issuance and sale by the Company to the 2021 Investors of an aggregate of 215,625 shares (the “Shares”) of the Company’s Common Stock, and warrants (the “Series K Warrants”) to purchase an aggregate of 161,719 shares (the “Warrant Shares”) of Common Stock, at a combined offering price of $32.00 per share (the “2021 Financing”). The Series K Warrants have an exercise price of $34.00 per share and are exercisable for a period of 5.5 years. The aggregate gross proceeds for the sale of the Shares and Series K Warrants were approximately $6.9 million, before deducting the Placement Agent’s fees and expenses and other offering expenses payable by the Company, of approximately $700,000. Pursuant to an engagement agreement dated as of February 8, 2021 (the “2021 Engagement Agreement”), by and between the Company and the Placement Agent, the Company agreed to pay the Placement Agent cash fees equal to (i) 7.5% of the gross proceeds received by the Company from certain investors in the 2021 Financing, and (ii) 6.0% of the gross proceeds received by the Company from certain investors that had pre-existing relationships with the Company. In addition, the Placement Agent received a one-time non-accountable expense fee of $10,000, up to $50,000 for fees and expenses of legal counsel and other out-of-pocket expenses and $10,000 for clearing expenses. Pursuant to the 2021 Engagement Agreement, the Company also agreed to issue to the Placement Agent, or its designees, warrants to purchase up to 7.5% of the aggregate number of Shares sold to the 2021 Investors, or warrants to purchase up to 16,172 shares (the “2021 Placement Agent Warrants”) of the Company’s Common Stock. The 2021 Placement Agent 2 Warrants have substantially the same terms as the Series K Warrants, except that the exercise price of the 2021 Placement Agent Warrants is $40.00 per share. The 2021 Engagement Agreement contained indemnity and other customary provisions for transactions of this nature.
The 2021 SPA contained certain restrictions on the Company’s ability to conduct subsequent sales of the Company’s equity securities. In particular, we were prohibited from entering into or effecting a Variable Rate Transaction (as defined in the 2021 SPA) until February 11, 2022; provided, however, the Company may enter into and effect an at-the-market offering facility with the Placement Agent.
The number of shares of the Company’s Common Stock into which each of the Series K Warrants is exercisable and the exercise price therefore are subject to adjustment, as set forth in the Series K Warrants, including adjustments for stock subdivisions or combinations (by any stock split, stock dividend, recapitalization, reorganization, scheme, arrangement or otherwise).
During the three months ended December 31, 2022, no Series K Warrants or Placement Agent 2 Warrants were exercised. As of December 31, 2022, up to 161,719 and 16,172 shares may be acquired upon the exercise of the Series K Warrants and Placement Agent Warrants, respectively.
Common Stock
On February 17, 2021, the Closing Date of the 2021 Financing, the Company issued 215,625 shares of Common Stock.
Equity Value of Warrants
The Company accounted for the Series K Warrants and the Placement Agent 2 Warrants relating to the aforementioned February 2021 Registered Direct Offering in accordance with ASC 815-40, Derivatives and Hedging. Because the Series K Warrants and the Placement Agent 2 Warrants are indexed to the Company’s stock, they are classified within stockholders’ deficit in the accompanying consolidated financial statements.
