Footnote F1

On March 13, 2025, the ownership of Title 19 Acies, a series of a Delaware limited liability company, was assigned to Skye Peak Partners LLC, a Delaware limited liability company ("SPP"), effective as of January 1, 2025. In connection with such assignment, the management of Title 19 Acies changed from the Reporting Person as sole manager to Emmett Gordon and Michael Youniss as managers, and the Reporting Person does not otherwise have investment control over the shares of the Issuer held by SPP. Accordingly, the Reporting Person no longer has a pecuniary interest in shares of the Issuer held by Title 19 Acies.

SEC remarks

The Issuer's Form 10-Q filed on August 13, 2025 provides that as of such date, the Issuer had 51,806,497 Common Shares outstanding. Based on this number and other shares included in the denominator of the calculation of the Reporting Person's ownership, the Reporting Person's ownership has dropped below 10% as of the date of filing this late Form 4. However, based on the publicly available number of outstanding shares reported prior to when this Form 4 was due, the Reporting Person held more than 10% at such time the Form 4 was due.
