• Shares owned after transaction: 19,744,585 Class B ordinary shares (these were received in exchange for his Legacy Horizon holdings).
• Relevant footnotes:
  • F1: Each Class B share is convertible at any time into one Class A ordinary share (1:1).

Context This was a corporate-transaction acquisition tied to the business combination (not a market buy or option exercise). Because no dollar amount was reported on the Form 4, retail investors should consult the company’s Form F-4 and the market price of Horizon Quantum (HQ) to estimate the economic value. The filing appears to have been submitted one business day after the usual two-business-day reporting deadline.
