SCHEDULE 13D




Comment for Type of Reporting Person:
American Ventures LLC, Series XXIV XWELL, directly owns 31,333 Series H Convertible Preferred Stock, convertible into 66,666,669 shares of the Issuer's common stock, and 66,666,669 warrants, exercisable into 66,666,669 shares of the Issuer's common stock. Dominari Holdings Inc. directly owns 5,248,000 warrants, exercisable into 5,248,000 shares of the Issuer's common stock. The Series H Convertible Preferred Stock has no voting rights. Further, the Series H Convertible Preferred Stock and the warrants each contain provisions that prohibit conversion or exercise to the extent that, after giving effect to such conversion or exercise, that holder and its affiliates would beneficially own more than 4.99% of the Issuer's outstanding common stock as calculated in accordance with Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "Beneficial Ownership Limitation"). Accordingly, the shares reported in Rows 8, 10, and 11 represent the maximum number of shares that may be beneficially owned without violating such limitation. The Reporting Persons currently do not beneficially own any shares of the Issuer's common stock for purposes of Rule 13d-3. Accordingly, each Reporting Person disclaims beneficial ownership of any shares of common stock issuable upon conversion or exercise of the securities described herein to the extent that such conversion or exercise would cause such Reporting Person to exceed the Beneficial Ownership Limitation. The percent of class represented by the amount in Row 13 is based on 5,766,703 shares of the Issuer's common stock issued and outstanding as of November 11, 2025, as reported in the Issuer's Quarterly Report on Form 10-Q filed with the SEC on November 14, 2025, plus 302,900 shares of common stock, which is the maximum number of shares of common stock that may be acquired by the Reporting Persons upon conversion or exercise of their securities without exceeding the Beneficial Ownership Limitation.
