Context

• These are sponsor private units common to SPAC structures (institutional sponsor—not an individual executive). The warrants are not immediately exercisable and have a $11.50 strike with multi-year expiration, so they represent potential future dilution rather than immediately tradeable shares.
• Purchases by a sponsor reflect acquisition of founder/private units rather than open-market purchases of public float; treat accordingly when evaluating insider signals.
