As described in this Amendment, as of August 17, 2026, the second tranche of the Warrant, representing 6,000,000 shares of Common Stock, became exercisable within 60 days. Together with the 4,000,000 shares underlying the first tranche of the Warrant, an aggregate of 10,000,000 shares of Common Stock underlying the Warrant are exercisable within 60 days. The Reporting Person has not exercised any portion of the Warrant and does not currently hold any shares of Common Stock. The foregoing has not changed the Reporting Person's investment intent as described in the Schedule 13D.

Percentage of Class

As of August 17, 2026, the Reporting Person may be deemed to beneficially own 5,617,689 shares of Common Stock, representing approximately 9.99% of the outstanding Common Stock. The percentage is calculated based on 50,615,437 shares of Common Stock outstanding as of July 27, 2026, as reported in the Issuer's Quarterly Report on Form 10-Q filed on July 30, 2026, plus the 5,617,689 shares issuable to the Reporting Person upon exercise of the Warrant within 60 days. As of August 17, 2026, 10,000,000 shares underlying the first and second tranches of the Warrant are exercisable within 60 days. However, the Beneficial Ownership Limitation restricts the Reporting Person from exercising the Warrant to the extent that, after giving effect to such exercise, the Reporting Person would beneficially own more than 9.99% of the outstanding Common Stock. Accordingly, only 5,617,689 shares are included in the Reporting Person's beneficial ownership. The Reporting Person disclaims beneficial ownership of any shares issuable upon exercise of the Warrant in excess of the Beneficial Ownership Limitation.

Number of Shares

Upon and following exercise of the Warrant, the Reporting Person will have sole voting power and sole dispositive power with respect to 5,617,689 shares of Common Stock issuable upon such exercise. The Reporting Person has not exercised any portion of the Warrant and does not currently have voting or dispositive power over any shares of Common Stock.

Transactions

Except as described in this Amendment, the Reporting Person has not effected any transaction in the Common Stock during the past 60 days. The change in the Reporting Person's beneficial ownership resulted solely from the second tranche of the Warrant becoming exercisable within 60 days of August 17, 2026, and not from the Reporting Person's exercise of the Warrant or any acquisition or disposition of Common Stock.
