restricted common stock financial

"Reporting Person was granted an aggregate 170,000 shares of restricted common stock"

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.
