What Happened

• Irene Page, Chief Accounting Officer of Smurfit Westrock plc, was granted 3,199 restricted stock units (RSUs) on 2026-03-11 (an award, code A). The RSUs are reported at $0 acquisition price because they are contingent units, not a cash purchase.
• On 2026-03-12, 556 ordinary shares were withheld/disposed to satisfy tax withholding obligations at a reported price of $42.20 per share, yielding a value of $23,463 (code F). This withholding is routine to cover taxes upon vesting/settlement and does not necessarily signal an open-market sale by the insider.

Context

• RSUs are a form of compensation that represent a contingent right to receive ordinary shares if and when they vest; the grant itself is not a market purchase. The subsequent withholding of shares is a common, administrative step to satisfy tax obligations and is different from an open-market sale intended to realize investment proceeds.
