restricted shares financial

"represents restricted shares that will become vested on the date that is the earlier"

Restricted shares are company stock that cannot be sold or transferred immediately because they are subject to legal or contractual limits, such as a required holding period or performance conditions. They matter to investors because these locked-up shares can affect a company’s available stock for trading, future dilution, and insider incentives—imagine a gift that can’t be cashed until certain conditions are met, which changes when and how much supply can suddenly enter the market.
