Key Details

• Primary transactions:
  • 2026-05-21: Exercise/conversion of derivative (code M) — 6,142 shares acquired (then disposition entries reported).
  • 2026-05-21: Payment of exercise price/tax withholding (code F) — 3,207 shares disposed at $36.95/share = $118,499.
  • 2026-05-20: Grants (code A) — 11,538 and 5,409 derivative awards (reported $0.00; contingent/RSU-style).
• Footnotes provided:
  • Each restricted stock unit equals a contingent right to one ordinary share.
  • One stock option award and one RSU award vest in full on 2027-05-20.
  • One award is noted as fully vested as of grant/issuance.
• Shares owned after the transactions are not specified in the provided filing extract.
• Filing: Report filed 2026-05-22 for transactions on 2026-05-20/21 — appears to be filed within the standard Form 4 timeframe (generally within 2 business days), so not indicated as late.

Context

• This appears to be a typical option exercise with a sell-to-cover/tax-withholding step: Cooke exercised options (or converted other derivative awards) and surrendered a portion of the resulting shares to meet tax/exercise obligations rather than making a separate cash payment. Such sell-to-cover transactions are common and do not, by themselves, indicate a change in insider sentiment.
• The grants reported (11,538 and 5,409 units) are contingent/derivative awards with scheduled vesting (mostly vesting 2027-05-20 except one award already noted as fully vested). These future vesting dates mean those shares are not yet freely tradeable until they vest.
