Context

• Withholding shares to cover tax on RSU vesting is a routine, administrative action and generally does not signal a deliberate decision to reduce exposure to the company’s stock. It differs from an open-market sale where the insider receives cash proceeds.
• For retail investors, purchases and open-market sales by insiders often carry more informational weight than tax-withholding dispositions like these.
