Guardant Health CTO Darya Chudova Exercises RSUs; 7,005 Shares Withheld

What Happened

  • Darya Chudova, Chief Technology Officer of Guardant Health, had multiple restricted stock units (RSUs vest) on 2026-04-01. A total of 13,029 shares converted (acquired) from RSUs (1,339 + 1,667 + 3,324 + 6,699). To cover tax withholding, the company retained (disposed) 7,005 of those shares at $91.15 per share, totaling $638,506. After withholding, Chudova netted an additional 6,024 shares of common stock.
  • This was a compensation-related vesting event (RSU conversion), not an open-market purchase or voluntary sale.

Key Details

  • Transaction date: 2026-04-01; Form filed: 2026-04-02 (timely).
  • Conversion/derivative code: M (exercise/conversion of RSUs) — shares shown as acquired at $0.00 (typical for RSU vesting).
  • Tax withholding: F code — 7,005 shares retained by the company at $91.15/share for $638,506 (per footnote F1, retained to meet tax obligations and not in excess of liability).
  • Net change to beneficial ownership: +6,024 shares (13,029 vested − 7,005 withheld).
  • Footnotes F2–F6 explain the RSU grants and vesting schedules (grants from 2022, 2023, 2024, 2025 with staggered vesting); F1 confirms the retention was for tax withholding.
  • Shares owned after the transaction were not provided in the excerpt.

Context

  • This was a routine vesting and tax-withholding transaction (cashless/net settlement), common for executives receiving RSUs; it does not reflect an open-market buy or a discretionary sale.
  • Such vesting events are compensation-related and typically are not interpreted as a direct bullish or bearish signal.
