Financial Analyst

TL;DR Minor insider selling under a disclosed 10b5-1 plan; holdings remain substantial and disclosures include weighted-average prices.

The Form 4 documents 16 sale transactions totaling 7,665 Class A shares executed on 08/07/2025 under a Rule 10b5-1 plan adopted February 20, 2025.

Corporate Governance Expert

TL;DR Sales executed under a pre-established 10b5-1 plan with explicit footnote disclosure; governance implications appear limited.

The insider disclosures identify the transactions as sales effected pursuant to a 10b5-1 plan, and the filing provides weighted-average prices and intraday ranges in footnotes for each block. Holdings remain in an indirect trust vehicle, with 283,605 Class A shares reported after the disposals. Given the pre-arranged nature and the level of disclosure, the filing raises limited immediate governance concerns based on the information provided.
