restricted shares financial

"Reflects 1,511 restricted shares issued pursuant to the terms of the BankUnited, Inc. Amended and Restated 2023 Omnibus Equity Incentive Plan."

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.
