4 terms

restricted shares financial

"As of June 2, 2026, 1,843 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.

Employee Stock Option (right to buy) financial

"security_title: "Employee Stock Option (right to buy)" with 2,620 shares."

tax-withholding disposition financial

"41 shares were withheld ... 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.

grant/award acquisition financial

"transaction_action: "grant/award acquisition" for share and option grants."
