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). The payout depends on relative total stockholder return against S&P 500 companies over December 22, 2025 to December 22, 2028, and can range from zero to up to 600,000 shares. For shareholders, the award ties Kurtz's pay to stock performance relative to the index, while the company says it is intended to retain him.
Target award of 300,000 PSUs; no shares are earned if relative TSR falls below the 25th percentile of S&P 500 companies, and up to 600,000 shares are possible at or above the 90th percentile.
Three-year performance period runs from December 22, 2025 to December 22, 2028.
The filing cites a share price of $483.14 and market capitalization of $121.3 billion as of December 22, 2025.
