restricted stock grant financial

"Represents fully vested shares of restricted stock grant pursuant to the Issuer's 2023 Equity Incentive Plan"

A restricted stock grant is an award of company shares given to an employee or executive that cannot be sold or transferred until certain conditions are met, such as staying with the company for a set time or hitting performance goals. For investors, it signals how the company ties pay to future performance and can affect the number of shares outstanding and management’s incentives—think of it as a wrapped gift you only keep once you meet the requirements.
