Form 4: Bruker CFO reports RSU tax withholding at ~$30.4 per share

Rhea-AI Filing Summary

Herman Gerald N., Executive Vice President and CFO of Bruker Corporation, reported the withholding of vested restricted stock units to satisfy tax obligations. The Form 4 shows three withholding transactions over August 9–11, 2025: 1,846 shares on 08/09 at $30.43, 1,380 shares on 08/10 at $30.43, and 1,420 shares on 08/11 at $30.78. The company’s explanatory note states these shares were withheld to cover taxes arising from vesting of previously granted RSUs.

Following the reported transactions, the filing lists beneficial ownership declining across those dates to 79,539, then 78,159, and finally 76,739 shares held directly by the reporting person. These entries are recorded under Transaction Code F and are presented as direct ownership on the Form 4.

Positive

• Reporting person identified with title (Executive Vice President, CFO), clarifying the filer’s role and direct ownership status.

Negative

• Beneficial ownership decreased across the reported dates from 79,539 to 76,739 shares due to withheld RSU shares.
• Multiple withholding events occurred over three consecutive days, creating several line items that require reconciliation for tracking ownership changes.

Insights

Corporate Governance Expert

TL;DR: Routine tax-withholding of vested RSUs by a senior executive; procedural disclosure, not a market sale.

The reported transactions are described explicitly as shares withheld to satisfy tax withholding obligations on vested restricted stock units, which is a common compensation-related event. The three withholdings across consecutive days total the reported amounts on 08/09/2025, 08/10/2025 and 08/11/2025 and are recorded with Transaction Code F. From a governance and disclosure standpoint, the filing meets Section 16 reporting requirements and clarifies that these were not open-market dispositions but administrative withholdings tied to compensation vesting.

Securities Analyst

TL;DR: Insider filings show routine RSU tax withholding; impact on float and executive ownership is minimal.

The Form 4 details three small withholding events totaling the stated share amounts, with per-share prices shown at $30.43 and $30.78. The filing provides the beneficiary counts after each transaction, ending at 76,739 shares directly owned. For investors, these transactions are administrative and do not indicate active selling intent; they simply document the company withholding shares to cover taxes associated with vested RSUs.
