Restricted Stock Units financial
"The filing describes transactions involving "Restricted Stock Units" that convert into common stock upon vesting."
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
"The RSU grant is labeled as a "Grant, award, or other acquisition" of a 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.
Annual Meeting of Stockholders financial
"100% of the RSUs shall vest on the earlier of the one year anniversary of the date of grant or the next Annual Meeting of Stockholders."
continued service financial
"RSU vesting is subject to the Reporting Person's continued service with the company."
