Restricted Stock Units financial
"On May 15, 2025, the Reporting Person was granted 9,789 time-vested restricted stock units ("RSUs") pursuant to the Amkor Technology, Inc. 2021 Equity Incentive Plan"
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.
dividend equivalent units financial
"0.0573 of the 2025 RSUs, which had accrued as dividend equivalent units ("DEUs") with each DEU representing an additional RSU"
Dividend equivalent units are bookkeeping credits that mirror cash dividends paid on actual shares, granted to holders of stock-based awards such as restricted stock units or deferred compensation. They matter to investors because they increase a company’s reported employee compensation cost and can lead to issuance of more shares or cash payouts over time, similar to extra pay linked to ownership that affects shareholder dilution and corporate cash flow.
2021 Equity Incentive Plan financial
"granted 9,789 time-vested restricted stock units pursuant to the Amkor Technology, Inc. 2021 Equity Incentive Plan, as amended"
time-vested financial
"Reporting Person was granted 9,789 time-vested restricted stock units ("RSUs") pursuant to the Amkor Technology, Inc. 2021 Equity Incentive Plan"
Time-vested describes a right—such as stock options, restricted shares, or pension benefits—that becomes fully owned by an individual only after they have waited for or worked through a specified period. For investors, it matters because these delayed ownership rules affect when insiders or employees can sell shares, which influences share supply, executive incentives, and the timing of potential stock dilution or insider-driven stock sales.
award agreement financial
"pursuant to the Amkor Technology, Inc. 2021 Equity Incentive Plan, as amended and the applicable award agreement (the "2025 RSUs")"
An award agreement is a legal contract that spells out the terms of a pay or equity grant—such as stock options, restricted shares, or cash bonuses—given to an employee, director or consultant. It describes what is being granted, any conditions for keeping it (for example, earning it over time or meeting performance targets), and what happens if the person leaves or breaks rules. Investors care because these agreements affect company costs, potential share dilution and how executives are motivated and rewarded.
