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.

Amended and Restated 2023 Omnibus Equity Incentive Plan financial

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

grant date 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."

The grant date is the day a company formally gives an employee or contractor the right to receive stock-based compensation, such as stock options or restricted shares. It matters to investors because it fixes key terms—like the price, the start of the ownership clock, and when the award will affect the company’s financial statements and share count—so it can influence dilution, reported expenses, and potential future selling pressure.

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."
