Equity [Abstract] |
Capital Structure | 14. Capital Structure The Company has 200 million shares of common stock authorized with a par value of $0.0001 per share and 50 million shares of preferred stock authorized with a par value of $0.0001 per share. As of September 30, 2022 and June 30, 2022, the Company had 3,121,471 and 1,928,941 common shares outstanding, respectively, and zero preferred shares outstanding, respectively. Included in the common stock outstanding are 73,164 shares of unvested restricted stock issued to executives, directors and employees. On June 8, 2020, the Company filed a shelf registration statement on Form S-3, which was declared effective by the SEC on June 17, 2020. This shelf registration statement covered the offering, issuance and sale by the Company of up to an aggregate of $100.0 million of its common stock, preferred stock, debt securities, warrants, rights and units (the “2020 Shelf”). As of September 30, 2022, approximately $43.0 million remains available under the 2020 Shelf. On June 4, 2021, the Company entered into a sales agreement with a sales agent, to provide for the offering, issuance and sale by the Company of up to $30.0 million of its common stock from time to time in “at-the-market” offerings under the 2020 Shelf (the “ATM Sales Agreement”). During the quarter ended September 30, 2022, the Company issued an additional 31,407 shares of common stock under the ATM Sales Agreement, with total net proceeds of approximately $0.4 million. As of September 30, 2022, approximately $11.8 million of the Company’s common stock remained available to be sold pursuant to the ATM Sales Agreement. On September 28, 2021, the Company filed a shelf registration statement on Form S-3, which was declared effective by the SEC on October 7, 2021. This shelf registration statement covered the offering, issuance and sale by the Company of up to an aggregate of $100.0 million of its common stock, preferred stock, debt securities, warrants, rights and units (the “2021 Shelf”). As of September 30, 2022, approximately $82.4 million remained available under the 2021 Shelf. On August 11, 2022, the Company closed on an underwritten public offering (the “August 2022 Offering”), pursuant to which we sold an aggregate of (i) 1,075,290 shares of its common stock, (ii) and, in lieu of common stock to certain investors that so chose, pre-funded warrants (the “Pre-Funded Warrants”) to purchase 87,500 shares of its common stock, and (iii) accompanying warrants (the "Common Warrants") to purchase 1,265,547 shares of its common stock. The shares of common stock and the Pre-Funded Warrants were each sold in combination with corresponding Common Warrants, with one Common Warrant to purchase one share of common stock for each share of common stock or each Pre-Funded Warrant sold. The combined public offering price for each share of common stock and accompanying Common Warrant was $8.60, and the combined offering price for each Pre-Funded Warrant and accompanying Common Warrant was $8.58, which equated to the public offering price per share of the common stock and accompanying Common Warrant, less the $0.001 per share exercise price of each Pre-Funded Warrant. The Pre-Funded Warrants were exercised in full in August 2022. The Common Warrants have an exercise price of $8.60 per share of common stock and are exercisable for a period of five years from issuance. The Company raised $10.0 million in gross proceeds through the August 2022 Offering before underwriting fees and other expenses of $0.9 million. The Pre-Funded and Common Warrants have a combined fair value of approximately $6.0 million at issuance and are classified as derivative warrant liabilities in the Company’s financial statements. (See Note 16 – Warrants).
