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.

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

vest in full financial

"The restricted shares have a grant date of May 21, 2026, and will vest in full on the earlier of the first anniversary of the date of grant or the date of the issuer's next annual meeting of shareholders."

annual meeting of shareholders financial

"will vest in full on the earlier of the first anniversary of the date of grant or the date of the issuer's next annual meeting of shareholders"

A yearly gathering where a company’s owners (shareholders) vote on key items like electing the board, approving executive pay, and ratifying auditors, and receive updates on performance and strategy. Think of it as an annual town hall for owners: it matters to investors because outcomes and disclosures can affect leadership, corporate direction, dividend and governance policies, and therefore the company’s risk and potential return.
