Restricted Share Unit financial

"Consists of a grant of RSUs awarded to the Reporting Person"

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"

Ordinary Shares financial

"underlying security title "Ordinary Shares""

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.
