Smurfit Westrock (SW) President NA Laurent Sellier Receives RSU Award

What Happened Laurent Sellier, President and Chief Executive Officer, North America (including Mexico) received restricted stock unit (RSU) awards on March 18, 2026 (225 RSUs and 358 RSUs — total 583 RSUs granted at $0). On March 19, 2026, 30 ordinary shares were withheld/disposed at $38.58 per share to satisfy tax withholding obligations, generating proceeds of roughly $1,157. The 358-unit award is shown as a derivative/awarded dividend-equivalent accrual tied to the company’s quarterly dividend.

Key Details

  • Transaction dates: RSU grants on 2026-03-18; tax-withholding disposition on 2026-03-19. Filing date: 2026-03-20 (timely).
  • Prices/values: RSUs granted at $0 (award). 30 shares withheld/disposed at $38.58 each → about $1,157.
  • Shares owned after transaction: Not disclosed in this filing.
  • Notable footnotes:
    • F1: Additional RSUs reflect dividend equivalents from a $0.4523 quarterly dividend; each RSU = right to receive one ordinary share.
    • F2: 30 ordinary shares were withheld to satisfy tax withholding for dividend equivalents that vested/settled on or about March 19, 2026.
    • F3: Separately, 30,972 restricted stock units are scheduled to vest and be settled in February 2027.
  • Transaction type: Award/grant of RSUs (A) and tax-withholding disposition (F), not an open-market sale.

Context These entries reflect receipt of equity compensation (RSUs) and routine withholding to cover taxes on vested dividend equivalents. RSU grants are not cash purchases and do not necessarily signal buy/sell sentiment; the 30-share disposition was a withholding event rather than a voluntary sale. The filing appears timely under Form 4 reporting rules.
