Madsen Julia 4

What Happened

• Julia Madsen, Senior Vice President and GM, Life Sciences at STERIS plc, had 208 ordinary shares withheld to satisfy tax withholding obligations when 578 restricted shares vested on June 1, 2026. The filing reports the 208-share withholding as a disposition with a reported value of $0 (shares were surrendered to cover taxes; the vested shares were valued at the NYSE closing price on June 1, 2026).

Key Details

• Transaction date: June 1, 2026; Form 4 filed June 3, 2026 (appears timely).
• Transaction code: F (tax withholding on vesting); reported disposition: 208 shares @ $0.00.
• Vesting: 578 restricted shares vested on June 1, 2026; 208 of those were withheld for taxes, leaving 370 net shares delivered to the insider.
• Shares remaining restricted: As of June 1, 2026, 3,425 ordinary shares remain subject to restrictions, with scheduled lapses: 352 on June 2, 2026; 666 on June 3, 2026; 542 on June 4, 2026; 666 on June 3, 2027; 542 on June 4, 2027; and 666 on June 5, 2028 (per footnote).
• Footnotes: F1 confirms the withholding amount was determined by the issuer and based on the NYSE close price that day; F2 lists the remaining restricted-share vesting schedule.

Context

• This was a tax-withholding event tied to RSU vesting (not an open-market sale or purchase). Such withholdings are routine and reflect tax compliance rather than a directional bet on the stock. The filing does not disclose a cash value for the 208 shares beyond noting they were valued at the NYSE close on June 1, 2026.
