Context

• The derivative activity reflects conversion/exchange of Class B Units into Class A shares (M = exercise/conversion). The conversion price reported was $0.00, and some converted shares were cancelled to the issuer (redemption), per footnotes.
• Some of the sold shares represent Vanderhook’s pro rata portion of larger dispositions by Capital V LLC executed under a 10b5‑1 plan; that means the trades may have been pre‑planned and not discretionary at the time of sale.
• These are sales (liquidity/portfolio management) rather than purchases; sales are common and do not by themselves signal management views on company prospects.
