Equity [Text Block] | Note 14 - Stockholders’ Equity The Company has 50.0 million shares of preferred stock authorized with a par value of $0.0001 per share and no preferred shares issued and outstanding. The Company has 200.0 million shares of common stock authorized with a par value of $0.0001 per share and as of September 15, 2025, June 30, 2025, and June 30, 2024, the Company had 9,911,913, 8,976,913 and 5,972,638 shares of common stock issued and outstanding, respectively. As of June 30, 2025, included in common stock outstanding are 32,916 shares of unvested restricted stock issued to directors, executives and employees. On September 26, 2024, the Company filed a shelf registration statement on Form S-3, which was declared effective by the SEC on October 15, 2024. This shelf registration statement covers 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 “2024 Shelf”). Through the filing date of this report, $100.0 million remains available under the 2024 Shelf. This availability is subject to the SEC’s “baby shelf” limitation as set forth in SEC Instruction I.B.6 limitation to the Form S-3. In June 2025, the Company raised gross proceeds of $16.6 million from the issuance of (i) 2,806,688 shares of its common stock, at a public offering price of $1.50 (the “June 2025 Common Stock”), and 8,233,332 prefunded warrants at a public offering price of $1.4999 to purchase 8,233,332 shares of its common stock at an exercise price of $0.0001 per share (the “June 2025 Prefunded Warrants”). The Company received $14.8 million in proceeds net of underwriting commissions and offering expenses and intends to use the net proceeds from the offering for working capital, general corporate purposes and to enable the Company to exclusively commercialize EXXUA. From July 2025 through the filing of this report, a total of 935,000 of the June 2025 Prefunded Warrants were exercised to 935,000 shares of common stock. See Note 16 - Warrants for further detail.
