Burton Karen L 4

What Happened

• Karen L. Burton, Senior Vice President and Chief Financial Officer of STERIS plc, was granted/received stock awards and a derivative award and had a small option/vesting-related disposition on June 2, 2026. Specifically, she acquired 5,325 ordinary shares (award), was granted a derivative award of 18,564 shares (option/award), and 66 shares were disposed (withheld) upon exercise/conversion at $209.76 per share, generating $13,844 in value recorded for the disposition.

Key Details

• Transaction dates: June 2, 2026 (reported on Form 4 filed June 4, 2026 — within the normal 2-business-day window).
• Disposition price/value: 66 shares at $209.76 = $13,844 (these 66 were withheld to cover taxes).
• Awards/acquisitions: 5,325 ordinary shares (acquired) and 18,564-share derivative award (grant) reported as $0 acquisition price in the filing.
• Restricted/vesting notes: Footnote F1 states 10,239 of the ordinary shares are restricted with scheduled lapses from June 2026 through June 2029 (tranches listed in the filing). Footnote F2 says 66 shares were withheld from 225 restricted shares that vested on June 2, 2026 to satisfy tax withholding (valued at the NYSE close on June 2, 2026). Footnote F3 shows the 18,564-share option vests in four tranches of 4,641 on June 2, 2027; June 2, 2028; June 4, 2029; and June 3, 2030.
• Shares owned after transaction: not specified in the portions of the filing provided.

Context

• The 66-share disposition was a tax-withholding action tied to vested restricted shares (common practice), not an open-market sale of additional shares by the insider. The larger items are grants/awards and a multi-year option/vesting schedule — these are compensation-related and typically reflect long-term incentives rather than routine sales.
