On December 22, 2025, CrowdStrike's independent directors approved a performance-based equity award for President and CEO George Kurtz, with a target of 300,000 performance stock units (PSUs).

Briefs the number check holds back are not shown or counted. Also: the last 45 days, briefs by company, A–Z and the live SEC filings wire.
