Rule 10b5-1 trading plan regulatory

"These Ordinary Shares were sold under a Rule 10b5-1 trading plan adopted by the Reporting Person on February 11, 2026."

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

Restricted Share Unit financial

"Consists of a grant of restricted share unit awarded to the reporting person under the Seagate Technology Holdings plc 2022 Equity Incentive Plan."

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

"Restricted share unit awarded to the reporting person under the Seagate Technology Holdings plc 2022 Equity Incentive Plan."

open-market sale financial

"Transaction action classified as open-market sale of 989 Ordinary Shares at $880.19 per share."

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
