Insights

Corporate Governance Analyst

Indirect control creates meaningful disclosed stake through affiliated entities.

The filing shows indirect beneficial ownership via trusts and operating entities: combined holdings include 6,451,535 Class A shares and warrants for 1,800,000 shares exercisable at $11.50. The control path runs from trusts to CF Group Management, Inc., to Cantor Fitzgerald, L.P., then to the record holders.

The main dependencies are the legal relationships and trustee decision authority documented in the filing and the remaining warrant expiration on 11/17/2025. Monitor the exercise or transfer of the warrants before that date because they change potential share count and voting dynamics.
