restricted stock units ("RSUs") financial
"Represents a grant of restricted stock units ("RSUs")."
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
vest financial
"The RSUs vest as follows: 1/3 on the first anniversary"
A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.
stock options financial
"The stock options vest and become exercisable in fifty"
Stock options are agreements that give a person the right to buy or sell a company's stock at a specific price within a certain time frame. They are often used as a reward or incentive, similar to a coupon that can be used later if the stock price rises, allowing the holder to make a profit.
tranches financial
"exercisable in fifty equal monthly tranches beginning"
Tranches are portions or slices of a larger financing deal—such as a loan, bond issue, or equity round—that are released at different times or under different conditions. For investors they matter because each tranche can carry different risk, interest or payout terms and may be paid only if certain targets are met; think of funding as slices of a cake handed out as progress is made.
