Rhea-AI Filing Summary

• On June 17, 2025: Exercised 910,740 stock options at $0.1334 per share and sold them at an average price of $37.7787

Following these transactions, Chapman retains 390,329 shares of common stock held directly and 1,604,972 vested stock options exercisable until May 16, 2029.

These pre-planned sales may indicate portfolio diversification rather than a lack of confidence in the company.
