Restricted Stock Unit financial
"the reporting person was granted 70,223 restricted stock units, vesting 25% per year"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
Performance Stock Unit financial
"the reporting person was granted 70,223 Performance Stock Units, with each PSU award to vest"
A performance stock unit is a type of reward companies give to employees, usually managers, that depends on how well the company performs over time. If the company hits specific goals, the employee earns shares of stock, like earning a prize for reaching certain levels in a game. It motivates employees to work hard because their rewards are tied to the company's success.
Stock Options (Right to buy) financial
"the reporting person was granted 76,234 stock options vesting 25% on the first anniversary"
exercise price financial
"Stock Options (Right to buy) with an exercise price of 5.8800"
The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
vesting financial
"PSU award to vest subject to continued service according to the schedule and conditions"
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.
