Key Terms

3 terms

restricted common stock financial

"Represents shares of restricted common stock, which vest on the anniversary of the grant date"

Restricted common stock is company shares that carry limits on selling or transferring for a set period or until certain conditions are met, like time-based vesting or regulatory clearance. Think of them as shares in a locked box that gradually open; they can become freely tradable later but initially reduce the number of shares available on the market. Investors watch restricted stock because its eventual release can change a company’s share supply, affect stock price, and influence control and dilution.

vest financial

"which vest on the anniversary of the grant date, subject to the terms of the award"

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.
