Personalis (PSNL) CEO Christopher Hall Sells 7,459 Shares

Key Details

• Transaction date and price: 2026-09-18 — 7,459 shares at $16.22/share (total $120,985).
• Reason/footnote: F1 — shares automatically sold to cover tax withholding obligation from settlement of vested RSUs.
• Shares owned after the transaction: Not specified in this Form 4 filing.
• Filing date vs. transaction date: Form 4 filed 2026-09-22 (four days after the transaction). Form 4s are generally required within two business days, so the filing appears later than the typical deadline.

Context Sales to cover tax withholding on vested RSUs are common and routine; they don't necessarily indicate the insider's view on the company's prospects. There is no indication here of other planned sales (e.g., a 10b5-1 plan) or option exercise — the sale was purely to satisfy tax obligations associated with RSU vesting.
