Avantor, Inc. (AVTR) – SEC Form 4 filing
Company insider Corey Walker, President of Laboratory Solutions, reported a routine tax-related share withholding on 21 June 2025. The filing shows 2,730 common shares (transaction code F) were surrendered at an indicated price of $13.57 to satisfy statutory withholding obligations triggered by the vesting of restricted stock units (RSUs). After the transaction, Walker continues to hold 231,271 shares directly.
No derivative security activity, 10b5-1 plan disclosure, or additional insider transactions were reported. The small size of the disposition (≈1.2 % of Walker’s post-transaction holdings) and its tax-withholding nature make the event immaterial to the company’s capital structure and unlikely to influence the investment thesis for AVTR.
