What Happened

Tariq Musa, a director of Guardant Health (GH), converted restricted stock units into common shares on May 15, 2026 and then sold 116 shares in the open market on May 18, 2026. The file shows a conversion (exercise/conversion code M) of 250 shares at $0.00 on May 15 (acquired) and a corresponding derivative disposal of 250 shares at $0.00 on the same date. On May 18 he sold 116 shares at $95.96 each for proceeds of $11,131. These transactions are primarily disposals (sales/withholding) rather than purchases.

Context

• The $0.00 exercise/conversion price and the RSU footnote indicate these were restricted stock unit conversions (not option purchases). The 250-share derivative disposal at $0.00 is consistent with shares being withheld to satisfy tax withholding or similar settlement mechanics common when RSUs vest. The separate open-market sale of 116 shares generated cash proceeds; such sales are often for tax/liquidity purposes and do not by themselves indicate the insider’s view of the company’s prospects.
