Subsequent Events | Note 13. Subsequent Events Reverse Stock Split As disclosed in Note 1, effective January 2, 2024, the Company effected a 1-for-40 reverse stock split of its outstanding common stock. Public Offering On February 6, 2024, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Ladenburg Thalmann & Co. Inc., as the sole underwriter (the “Underwriter”), relating to the issuance and sale in a public offering (the “Offering”) of: (i) 480,000 shares of the Company’s common stock, (ii) pre-funded warrants to purchase up to 1,424,760 shares of common stock, (iii) Series A warrants to purchase up to 3,809,520 shares of common stock, (iv) Series B warrants to purchase up to 3,809,520 shares of common stock, and (v) up to 285,714 additional shares of common stock, Series A warrants to purchase up to 571,428 shares of common stock and Series B warrants to purchase up to 571,428 shares of common stock that may be purchased pursuant to a 45-day option to purchase additional securities granted to the Underwriter by the Company. The Underwriter partially exercised this option on February 7, 2024 for 82,500 shares of common stock, Series A warrants to purchase up to 165,000 shares of common stock and Series B warrants to purchase up to 165,000 shares of common stock. The combined public offering price of each share of common stock, together with the accompanying Series A warrants and Series B warrants, was $2.10, less underwriting discounts and commissions. The combined public offering price of each pre-funded warrant, together with the accompanying Series A warrants and Series B warrants, was $2.099, less underwriting discounts and commissions. The Offering, including the additional shares of common stock, Series A warrants and Series B warrants sold pursuant to the partial exercise of the Underwriter’s option, closed on February 8, 2024. The net proceeds from the Offering, including the additional shares of common stock, Series A warrants and Series B warrants sold pursuant to the partial exercise of the Underwriter’s option, after deducting underwriting discounts and commissions and other estimated Offering expenses payable by the Company and excluding any net proceeds from the exercise of the Series A warrants, Series B warrants and pre-funded warrants, were approximately $3.3 million. The Series A warrants and Series B warrants each have an exercise price of $2.25 per share and are immediately exercisable upon issuance. The Series A warrants expire on the five-year anniversary of the date of issuance and the Series B warrants expire on the six-month anniversary of the date of issuance. The pre-funded warrants have an exercise price of $0.001 per share, are exercisable immediately and may be exercised at any time until all of the pre-funded warrants are exercised in full. Subsequent to the closing of the Offering, as of March 18, 2024, the holders exercised pre-funded warrants for 1,001,110 shares of common stock. The exercise price and number of shares of common stock issuable upon exercise of the warrants is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting the common stock and the exercise price. Subject to limited exceptions, a holder may not exercise any portion of its warrants to the extent that the holder would beneficially own more than 9.99% or 4.99% (at the election of the holder) of the Company’s outstanding common stock after exercise. On February 8, 2024, pursuant to the Underwriting Agreement, the Company issued warrants to the Underwriter to purchase up to 139,108 shares of common stock at an exercise price of $2.625, subject to adjustments, which are exercisable at any time and from time to time, in whole or in part, until February 8, 2029, and have substantially similar terms to the Series A warrants.
