Insights

Securities Compliance Attorney

Form 144/A shows multiple resale transactions and a conversion-trigger clause for Class B shares.

The filing lists dated resale entries with exact share counts and gross proceeds for each transaction between 12/18/2025 and 02/19/2026

Careful readers should note the statement that Class B shares were acquired and "to be converted to Class A common shares in connection with any sales" dated 03/17/2026; this qualifier links conversion mechanics to sale events and may affect timing of any additional resale filings.

Equity Markets Analyst

Multiple, incremental dispositions by affiliated holders are documented; amounts are granular, dated, and traceable.

The excerpt provides per‑trade share counts and gross proceeds for named parties (e.g., Tim Vanderhook: 53,434 shares; T&L Vanderhook Trust: 31,566 shares on 12/18/2025), enabling precise audit of reported sales.

These entries represent disclosed reseller activity; cash‑flow treatment and any issuer proceeds are not stated in the excerpt. Subsequent filings would show additional conversions or resales tied to the conversion clause.
