Bruker (BRKR) 10% Owner Frank H. Laukien — Shares Withheld for Taxes

What Happened

• Frank H. Laukien, a 10% owner of Bruker Corporation (BRKR), had 4,838 shares withheld by the company on Aug 11, 2026 to satisfy tax withholding tied to the vesting of previously granted restricted stock units (RSUs). The withholding price was $57.02 per share, representing a disposition of shares valued at $275,863. This is a tax-withholding disposition (code F), not an open-market sale.

Context

• This was a cashless tax-withholding event associated with RSU vesting—common and generally not interpreted as a change in insider sentiment since shares were not sold into the market.
