What Happened Corey E. Thomas, CEO and Director of Rapid7, had 5,357 shares withheld by the company on May 15, 2026 to satisfy tax withholding obligations tied to the vesting of previously granted restricted stock units.

Context This was an administrative disposition to cover taxes on vested restricted stock units (a routine corporate payroll/tax action), not a market sale that necessarily signals the insider's view on Rapid7's stock. For retail investors, purchases are generally more informative than routine withholdings; this report documents compensation-related withholding rather than discretionary selling.
