Positive

• Adoption of a Rule 10b5-1 plan (adopted 06/03/2025) provides pre-planned sale execution and legal clarity
• Conversion of 42,898 Class B to Class A shares increased directly held Class A shares by 42,898
• Transparent pricing disclosure: sale range $17.84–$18.245 with weighted average $18.0154

Negative

• Net reduction in direct Class A holdings from the reported sales to 1,283,939 shares
• Some shares remain subject to forfeiture if underlying vesting conditions are not met, which could affect ultimate ownership
• Increase in freely tradable Class A float due to conversion may marginally dilute control tied to Class B shares

The reported sale price range was $17.84–$18.245 and the weighted average price is $18.0154. The conversion of 42,898 Class B shares to Class A increases the pool of publicly tradeable Class A shares.
