Context

• The Class B→Class A conversion is structural (one-for-one conversion right of Class B holders) and was reported as a derivative conversion; the filing shows both the conversion and the subsequent market sales/gift. Gifts do not necessarily signal the holder’s view of the company. Sales executed under a prearranged 10b5‑1 plan are typically pre-scheduled and may reflect planned liquidity rather than active trading based on current company information.
