WERNER ROBERT F. 4

What Happened

• Robert F. Werner, Chief Accounting Officer of Twist Bioscience, sold 164 shares on 2026-05-04 at $57.15 per share for total proceeds of about $9,372. The Form 4 was filed on 2026-05-06.
• This was a sale (not a purchase) and the filing’s footnote states the shares were sold to satisfy tax withholding obligations tied to RSU vesting — a mandated "sell-to-cover" rather than a discretionary trade.

Key Details

• Transaction date and price: 2026-05-04 — 164 shares sold at $57.15 each.
• Total proceeds: approximately $9,372.
• Shares owned after the transaction: not specified in the provided filing.
• Footnote: Sale executed to cover tax withholding for vested Restricted Stock Units (mandatory under the issuer’s election; not an opportunistic sale).
• Filing timeliness: Form 4 was filed on 2026-05-06 (two days after the transaction), which appears timely under standard Form 4 rules.

Context

• "Sell-to-cover" transactions are common when equity awards vest and typically reflect tax requirements rather than a manager’s view on the stock—these are generally considered routine and less informative about insider sentiment.
• For retail investors, routine tax-withholding sales by officers differ from voluntary, larger open-market sales, which can sometimes signal a change in conviction.
