Item 3 is hereby amended to add the following: On August 11, 2025, the Issuer entered into a securities purchase agreement (the "Securities Purchase Agreement") with several institutional accredited investors, including GEO, pursuant to which the Issuer agreed to issue and sell to the investors in a private placement (the "Private Placement") (i) an aggregate of 11,040,776 shares of Common Stock and (ii) pre-funded warrants to purchase an aggregate of 31,234,731 shares of Common Stock (the "Pre-Funded Warrants"). The Private Placement closed on August 13, 2025. In connection with the closing, GEO purchased (i) 1,734,184 shares of Common Stock at a purchase price of $1.42 per share; and (ii) Pre-Funded Warrants to purchase 5,311,810 shares of Common Stock (the "2025 GEO Pre-Funded Warrants") at a purchase price of $1.419 per Pre-Funded Warrant and with an exercise price of $0.001 per share of Common Stock. The exercise price of the 2025 GEO Pre-Funded Warrants is subject to customary adjustments. The 2025 GEO Pre-Funded Warrants are exercisable at the option of GEO at any time after their issuance; provided that the 2025 GEO Pre-Funded Warrants carry a limitation on exercise if it results in GEO beneficially owning in excess of 4.99% of the number of shares of Common Stock, which percentage can be increased or decreased at the option of GEO upon 61 days' prior notice not to exceed 19.99%. GEO now owns a total of 2,233,744 shares of Common Stock and a right, upon exercise of the 2025 GEO Pre-Funded Warrants, the Pre-Funded Warrants, GEO Class C Warrants and/or the GEO Warrants and taking into account their respective beneficial ownership limitations, to purchase up to 9,914 shares of Common Stock (the "Exercisable Shares") for a total deemed ownership of 2,243,658 shares of Common Stock (the "GEO Shares"). The working capital of GEO is the source of the funds for the purchase of the GEO Shares. No part of the purchase price of the GEO Shares is represented by funds or other consideration borrowed or otherwise obtained for the purpose of acquiring, holding, trading or voting the GEO Shares. The foregoing description of the Securities Purchase Agreement and the terms and conditions of the securities issued thereunder is qualified in its entirety by reference to the full text of the Securities Purchase Agreement, a copy of which is attached as Exhibit 10.1 to the Issuer's Form 8-K filed with the Securities and Exchange Commission (the "SEC") on August 12, 2025 (the "Form 8-K") and incorporated herein by reference.
