• Form 4 includes attorney-in-fact signature dated 10/10/2025, indicating formal execution and proper filing

Insights

Insider Transactions Analyst

Planned sale reduces insider stake but was executed under a 10b5-1 plan.

The CTO sold 70,524 Class A shares at $20, leaving 606,525 shares beneficially owned. The filing explicitly states the sale was made under a Rule 10b5-1 plan adopted in December 2024, which provides an affirmative defense for trades scheduled in advance.

This reduces his direct stake by a measurable amount; investors may note timing and size relative to total outstanding shares. Watch for any additional Form 4s that change holdings or show further plan activity within the next few months.

Securities Compliance Specialist

Documentation and signature show formal execution via attorney-in-fact.

The Form 4 includes a signed certification by an attorney-in-fact on 10/10/2025, consistent with procedural requirements. The filing marks the transaction code as S(1), indicating a sale under a standing plan rather than an open-market discretionary sale.

From a compliance view, the presence of a dated 10b5-1 plan and the formal signature reduce regulatory ambiguity; monitor for any amendments or additional disclosures that would affect transaction intent or timing.
