Context

• The conversion/exercise activity reflects exchange of Class B Units into Class A shares and subsequent cancellation — not a typical open‑market purchase or sale signal. The open‑market sales were executed under a 10b5‑1 plan through Capital V LLC, indicating scheduled disposition rather than an opportunistic trade. As always, these transactions are factual disclosures and do not by themselves indicate insider sentiment.
