tax-withholding disposition financial

"337 shares were withheld from the 1,157 restricted shares that vested on June 1, 2026. These 337 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

"337 shares were withheld from the 1,157 restricted shares that vested on June 1, 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.

vested shares financial

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

NYSE closing market price financial

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

restrictions lapse financial

"The restrictions on these ordinary shares lapse as follows: 846 on June 2, 2026; 1,252 on June 3, 2026;"
