Insights

Corporate Governance Analyst

Officer sold 35,145 shares under a 10b5-1 plan; holdings remain substantial.

The sale of 35,145 Class A shares at $80 was reported as a planned transaction under a Rule 10b5-1 trading plan adopted on 06/02/2025, which indicates the decision and price timing were pre-authorized rather than opportunistic. Continued direct ownership of 535,896 shares leaves the officer with a meaningful stake.

This transaction reduces insider concentration modestly but does not signal an immediate governance change. Investors may note the existence of an active trading plan and monitor future Form 4s for further scheduled disposals or changes to the plan within the next 6–12 months.
