Key Details
- Transaction date: March 1, 2026; Form 4 filed March 3, 2026 (timely).
- Awards: 3,500 RSUs and 6,430 RSUs granted (total 9,930 RSUs).
- Withheld (disposed) shares for taxes: 2,440 + 281 + 340 + 460 = 3,521 shares at $174.08 each; total value withheld ≈ $612,935.
- Net shares issued after withholding (9,930 granted − 3,521 withheld): 6,409 shares credited to Barkmann.
- Notable footnotes:
- F3: Performance-based RSUs for 2023–2025 performance period vested and settled March 1, 2026 after committee certification.
- F4–F7: The withheld shares reflect tax withholding for performance and time-based tranches (grants from 2023–2025); withholding prices were determined using closing prices on specified Feb 27 dates.
- F1 & F5–F7: Some awards are time-based RSUs with future vesting schedules (e.g., certain RSUs vest in installments beginning March 1, 2027).
- F2: Reporting person corrected a prior de minimis overstatement of shares beneficially owned; the filing updates the post-transaction ownership accordingly.
- Filing timeliness: Filed within the typical Form 4 window (March 1 transaction, March 3 filing) — not indicated as late.
Context
- These transactions are award grants and internal tax-withholdings, not open-market purchases or sales. The withheld shares represent a cashless method to satisfy tax obligations upon vesting (routine), not a market sale that would indicate a decision to liquidate shares.
- Codes: A = award/grant; F = payment of exercise price or tax liability (here, share withholding to cover taxes).
