Restricted Share Unit financial

"security_title: Restricted Share Unit"

A restricted share unit (RSU) is a promise by a company to give an employee a set number of company shares at a future date, typically after meeting time or performance conditions. For investors, RSUs matter because when they convert into actual shares they increase the number of shares outstanding (like unlocking more tickets in a game), which can dilute existing holders, and they align employee incentives with company performance, influencing behavior and long-term value.

2022 Equity Incentive Plan financial

"awarded to the Reporting Person under the Seagate Technology Holdings plc 2022 Equity Incentive Plan"

vesting financial

"such RSUs vested as to one-quarter of the shares on September 9, 2023"

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.

continuous employment financial

"Subject to the Reporting Person's continuous employment, such RSUs vested"
