Zangerle John Adam 4

What Happened

• John Adam Zangerle, Senior Vice President, General Counsel and Secretary of STERIS plc, had 1,157 restricted shares vest on June 1, 2026. To satisfy tax withholding obligations, 337 of those vested shares were withheld by the issuer (reported as a disposition under code F). The filing reports the withholding at $0 proceeds (the shares were retained to cover taxes); the vested award was valued at the NYSE closing price on June 1, 2026 per the footnote. Net shares delivered to Zangerle from this vesting were 820 (1,157 vested − 337 withheld).

Context

• This transaction is a routine tax-withholding event tied to RSU vesting, not an open-market sale or purchase. Withholding of shares to cover taxes is common and does not necessarily reflect the insider’s view of the company. The filing does not indicate an open-market sale of shares by the insider.
