Sellier Laurent 4

What Happened Laurent Sellier, President and Chief Executive Officer, North America (including Mexico) of Smurfit Westrock plc, was granted 25,178 restricted stock units (RSUs) on March 11, 2026 (reported as an award, code A). The RSUs were reported at $0.00 per unit. On March 12, 2026, 2,524 ordinary shares were withheld to satisfy the reporting person’s tax withholding obligation upon vesting/settlement of RSUs; those shares are reported at $42.20 each, totaling $106,513 (transaction code F). These actions reflect a compensation award and routine tax withholding — not an open-market purchase or a voluntary sale.

Context

• RSUs are compensation awards that give the holder a right to receive shares in the future according to a vesting schedule; they are not the same as an open-market purchase (which might be viewed as a bullish signal).
• The withheld shares are a routine tax-withholding mechanism (similar to a cashless settlement) and should not be interpreted as an intentional sale for investment reasons.
• For retail investors, awards signal executive compensation alignment with shareholders but do not necessarily indicate the insider’s private view on the stock’s near-term prospects.
