restricted stock units financial

"Shares automatically withheld upon settlement of restricted stock units to satisfy tax withholding obligations."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

tax withholding obligations financial

"Shares automatically withheld upon settlement of restricted stock units to satisfy tax withholding obligations."

closing price per share financial

"the price stated above is the closing price per share of Entegris common stock"

tax-withholding disposition financial

"transaction_action: "tax-withholding disposition""

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.
