Restricted Stock Units financial
"The transaction represents shares withheld by Amkor Technology, Inc. ... in connection with the vesting of certain restricted stock units"
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
"These shares were withheld to satisfy the Reporting Person's tax withholding obligations."
Equity Incentive Plan financial
"pursuant to the Issuer's 2021 Equity Incentive Plan, as amended, and the related award agreement."
An equity incentive plan is a program that gives employees, executives or directors the right to receive company stock or options to buy stock as part of their pay. Think of it as offering slices of future company profit to motivate people to boost long‑term performance; for investors it matters because it can align employee goals with shareholder value but also increases the number of shares outstanding, which can dilute existing ownership.
vesting financial
"RSUs which vest in five equal quarterly installments on each of June 30, 2025..."
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.
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.
