4 terms

restricted stock financial

"Amount represents the number of shares of restricted stock granted under the 2021 Stock Incentive Plan."

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

2021 Stock Incentive Plan financial

"shares of restricted stock granted under the 2021 Stock Incentive Plan."

vest financial

"The shares will vest in one installment beginning on May 28, 2027."

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.
