restricted stock units financial
"Reflects the partial disposal of restricted stock units granted to the reporting person on March 28, 2025"
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.
performance-based shares financial
"Reflects the partial disposal of performance-based shares of Company common stock, granted on March 9, 2026"
withholding taxes financial
"disposed shares, settled in cash, to satisfy withholding taxes applicable upon vesting of the March 28, 2025 grant"
Withholding taxes are amounts a payer or government takes out of payments — such as wages, interest, or dividends — before the recipient gets the money, functioning like a cashier keeping part of a bill to pay taxes on your behalf. For investors this matters because it reduces the cash they actually receive, affects net returns and yield calculations, and may require additional paperwork or treaty claims to recover or offset the withheld amount against final tax bills.
2022 Long Term Incentive Plan financial
"including performance-based restricted stock units, under the 2022 Long Term Incentive Plan"
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.
