Restricted Stock Units financial
"100% of the restricted stock units ("RSUs") granted on May 21, 2025 vested on May 20, 2026"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
derivative security financial
"transaction_code_description: Exercise or conversion of derivative security"
A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.
grant, award, or other acquisition financial
"transaction_code_description: Grant, award, or other acquisition"
vesting financial
"100% of the RSUs granted on May 20, 2026 will become vested on the earlier of (i) May 20, 2027 or (ii) the date of the next annual meeting of stockholders."
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.
