"Item 3. Source or Amount of Funds or Other Consideration." of the Schedule 13D is being amended by this Amendment No. 6 to add the following: On July 30, 2026, the Issuer, Corvus and certain other investors (collectively, the "Investors") of Sarborg Limited, a Cayman Islands company ("Sarborg"), entered into a Securities Purchase Agreement (the "Purchase Agreement") pursuant to which, the Investors sold to the Issuer, and the Issuer acquired from such Investors, an aggregate of 270 shares of Sarborg (the "Sarborg Shares") and in exchange as consideration the Issuer issued to the Investors pre-funded warrants (the "Pre-Funded Warrants") to purchase up to an aggregate of 12,131,770 shares of Common Stock, at an exercise price of $0.0001 per share. Pursuant to the Purchase Agreement, on July 30, 2026, Corvus received Pre-Funded Warrants to purchase up to 5,436,830 shares of Common Stock in exchange for 120 Sarborg Shares. The Pre-Funded Warrants included a Blocker (defined below) as well as a "cashless" exercise provision, wherein the holder of the Pre-Funded Warrant was entitled to receive a number of shares of Common Stock generally equal to the quotient obtained by dividing the market price minus the exercise price divided by the market price (as further described in the Pre-Funded Warrant). The exercisability of the Pre-Funded Warrants was subject to the receipt of Issuer stockholder approval and a 49.99% beneficial ownership limitation provision (the "Blocker"), which Blocker provided that each holder was prohibited from exercising such Pre-Funded Warrants if, as a result of such exercise, such holder, together with its affiliates and any persons acting as a group together with such holder or any of such affiliates, would beneficially own more than 49.99% of the total number of shares of Common Stock then issued and outstanding immediately after giving effect to such exercise. On August 28, 2026, at a special meeting of stockholders, the Issuer's stockholders approved the issuance of Common Stock upon the exercise of the Pre-Funded Warrants in an amount equal to or greater than 20% of the number of shares of Common Stock outstanding prior to such issuance, regardless of whether such shares are issued to one person or group or are more widely distributed. Also on August 28, 2026, following the certification of the results of the Issuer's special meeting of stockholders, Corvus exercised all of its Pre-Funded Warrants pursuant to the "cashless" exercise provision thereof and received 5,436,540 shares of Common Stock.
