• Sales executed as the Reporting Person’s pro rata portion of Capital V LLC sales and were made pursuant to a 10b5‑1 plan adopted March 18, 2025 (amended Sep 17, 2025).
• Reporting Person holds a one‑third interest in Capital V LLC and thus has an indirect pecuniary interest in the sold shares (see footnotes F1–F3, F5–F7 for weighted‑average price details and ranges).

Context

• The open‑market sales represent Vanderhook’s pro rata portion of sales by Capital V LLC under an established 10b5‑1 plan, not necessarily a personal discretionary sale. For retail investors this is typically treated as planned/automatic selling by an entity in which he has an ownership interest rather than a direct signal about company outlook.
• The conversion/exercise of Class B Units into Class A shares and the subsequent cancellation of Class B common stock are structural events tied to the LLC/share class mechanics (see footnotes). These conversions were reported with $0 consideration, indicating a one‑for‑one exchange rather than a cash purchase.
• No evidence in the filing that these were gifts or tax‑withholding related dispositions.
