restricted stock units ("RSUs") 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 (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

"plus an additional 104 dividend equivalent units ("DEUs"), which each represented an additional RSU subject to the same provisions"
Grantor Retained Annuity Trusts ("GRATs") financial
"trusts for the benefit of her immediate family members (other than grantor retained annuity trusts ("GRATs")) which own 3,713,610 shares"

Section 16 regulatory
"for purposes of Section 16 of the Securities Exchange Act of 1934, as amended ("Section 16")"
Section 16 is a U.S. securities law rule that governs the trading and disclosure obligations of company insiders — typically officers, directors and large shareholders — to promote transparency and deter unfair profit-taking. It requires insiders to publicly report their stock trades and allows companies or the issuer to reclaim quick, short-term profits from certain insider trades, like a scoreboard and a refund policy that help investors see and limit possible insider advantage.
