Restricted Share Units (RSUs) financial
"Represents restricted share units ("RSUs") granted to the reporting person"
Restricted share units (RSUs) are a form of employee pay where a company promises to give shares (or their cash value) to workers after certain conditions, usually time or performance, are met. For investors, RSUs matter because they can increase the number of shares outstanding and signal how management is being paid and incentivized—think of them as delayed bonuses that convert into ownership when vesting conditions are satisfied.
vesting financial
"The RSUs vested on October 1, 2026."
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.
