Insights

Equity compensation analyst

Routine tax withholding on RSU vesting; no open-market trading signal.

The transaction involves 109 ordinary shares withheld to satisfy tax obligations on 373 restricted shares that vested on June 1, 2026. The price is effectively the NYSE closing market price used to determine the tax value, not a voluntary sale.

Code F events are standard for equity awards and do not represent open-market buying or selling. Following this withholding, Kohler directly holds 9,533 ordinary shares, including 3,141 restricted shares with vesting dates extending to June 5, 2028, indicating an ongoing equity stake.

The footnote clarification that prior Form 4s misreported beneficially owned shares means this filing also cleans up historical ownership records. The economic signal is limited because there is no discretionary trade; it is a mechanical tax payment linked to compensation.

restricted shares financial

"As of June 1, 2026, 3,141 of these ordinary shares are restricted."

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.

tax-withholding disposition financial

"109 shares were withheld from the 373 restricted shares that vested on June 1, 2026."

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.

beneficially owned financial

"The shares beneficially owned were erroneously reported in prior Form 4s."

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

vesting financial

"109 shares were withheld from the 373 restricted shares that vested on June 1, 2026."

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

NYSE closing market price financial

"These vested shares were valued at the NYSE closing market price on June 1, 2026."
