The filing shows multiple conversions of **Class B** into **Class A** at a one-for-one rate with no expiration, followed by sales on 10/24/2025. Indirect holdings converted and sold: 480,878 (Prinz Family Trust), 250,000 (Benedikt F. Prinz 2019 Trust), and 250,000 (Marie Helene Prinz 2019 Trust). Direct sales totaled 19,122 shares. Reported weighted average sale prices were around $15.466 and $15.976 within the disclosed ranges.

After these sales, indirect **Class A** balances at those trusts are shown as zero. However, the trusts report continuing ownership of **Class B** shares (derivative line items) following the transactions: 6,430,568, 1,154,738, and 1,023,436, respectively. Direct beneficial ownership stands at 142,221 shares, including RSUs/PSUs that settle one-for-one into Class A subject to service and, for PSUs, performance milestones.

What to watch: additional conversions or sales from the remaining **Class B** holdings and changes to the 142,221 direct balance as RSUs/PSUs vest over time. Subsequent Forms 4 would indicate further activity beyond 10/24/2025, including any new conversions or disposition events.
