Guardant Health CIO Kalia Kumud Exercises RSUs; Shares Withheld

What Happened Kalia Kumud, Chief Information Officer of Guardant Health (GH), had 10,044 restricted stock units (RSUs convert to common shares) vest and converted into common stock on April 1, 2026. Of those shares, the company retained 5,092 shares to satisfy tax-withholding obligations, valued at $91.15 per share for a total withholding of $464,136.

Key Details

  • Transaction date: April 1, 2026; Form 4 filed April 2, 2026 (timely).
  • Activity: Multiple RSU vesting conversions (reported as derivative exercise/conversion, Code M) and tax-withholding (Code F).
  • Shares involved: 10,044 shares converted; 5,092 shares withheld by the company to cover taxes (withholding valued at $91.15/share; $464,136).
  • Net shares delivered to insider: 4,952 shares (10,044 converted minus 5,092 withheld).
  • Footnotes: F1 explains the company retained shares to meet tax withholding and not in excess of the tax liability. F2–F6 indicate the shares arose from RSU awards granted Nov 7, 2022; Dec 13, 2023; Nov 8, 2024; and Mar 12, 2025 with scheduled vesting (quarterly installments).
  • Shares owned after the transaction: Not specified in the filing.

Context

  • This was a routine RSU vesting/cashless-withholding event (company retained shares to satisfy tax obligations), not an open-market sale or purchase. For retail investors, such withholding is standard and does not itself signal a deliberate sell or buy decision by the insider.
  • Transaction codes: M = exercise/conversion of derivative securities (RSUs converted to common stock); F = payment of exercise price or tax liability (shares withheld).
