Insights

Equity compensation analyst

Routine tax withholding on RSU vesting; no open‑market sale.

The filing shows 600 STERIS ordinary shares withheld as taxes when 1,360 restricted shares vested at a value of $212.24 per share. This is coded as an F transaction, which represents tax-liability settlement using shares, not discretionary selling.

Following the transaction, Mary Clare Fraser holds 13,716 ordinary shares, with 5,359 still restricted and set to vest between 2027 and 2029. Because this is a standard equity-compensation and tax event, without open-market buying or selling, it is generally viewed as administratively neutral for outside shareholders.

tax-withholding disposition financial

"These 600 shares represent the value of the taxes required to be withheld"

A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.

restricted shares financial

"1,360 restricted shares that vested on June 4, 2026"

Restricted shares are company stock that cannot be sold or transferred immediately because they are subject to legal or contractual limits, such as a required holding period or performance conditions. They matter to investors because these locked-up shares can affect a company’s available stock for trading, future dilution, and insider incentives—imagine a gift that can’t be cashed until certain conditions are met, which changes when and how much supply can suddenly enter the market.

NYSE closing market price financial

"These vested shares were valued at the NYSE closing market price on June 4, 2026"
