Restricted Shares of Common Stock technical

"Restricted Shares of Common Stock"

Restricted shares of common stock are company shares that cannot be sold or transferred until specific conditions are met, such as a set time period, performance targets, or regulatory approvals; they are often granted to founders, employees or early investors. They matter to investors because when the restrictions lift those shares can enter the market and increase the supply, potentially diluting existing holders and changing the stock’s price, similar to a locked faucet being opened and more water joining the flow.
