Key Details

• Transactions and prices:
  • June 4, 2026: 1,889 shares withheld for taxes at $212.24/share (value $400,921) — tax withholding on vesting (code F).
  • June 4, 2026: 3,054 shares sold open market at $214.64/share (proceeds $655,511) (code S).
  • June 5, 2026: 1,374 shares sold open market at $212.00/share (proceeds $291,288) (code S).
• Post-transaction restricted holdings: Form notes 39,893 ordinary shares are restricted as of June 8, 2026, with remaining restriction lapse schedule: 7,912 on June 2, 2027; 5,937 on June 3, 2027; 4,283 on June 4, 2027; 7,912 on June 2, 2028; 5,937 on June 5, 2028; and 7,912 on June 4, 2029. (These are restricted-share counts, not total beneficial ownership.)
• Footnotes: 1,889 shares were withheld from the 4,283 restricted shares that vested on June 4, 2026; the withheld shares were valued at the NYSE closing price on June 4, 2026.
• Filing timeliness: Transactions occurred June 4–5 and the Form 4 was filed June 8, 2026. Form 4s are generally due within two business days of the transaction, so this filing appears to be later than the typical deadline.

Context

• The 1,889‑share disposition was a tax withholding tied to the vesting of restricted stock (a routine administrative step), while the other dispositions were open‑market sales. Sales by executives are common and do not, by themselves, prove a change in sentiment about the company.
