Key Terms

Restricted Share Unit financial

"Each restricted share unit represents the right to receive, at settlement, one share of common stock or cash"

A restricted share unit (RSU) is a promise by a company to give an employee a set number of company shares at a future date, typically after meeting time or performance conditions. For investors, RSUs matter because when they convert into actual shares they increase the number of shares outstanding (like unlocking more tickets in a game), which can dilute existing holders, and they align employee incentives with company performance, influencing behavior and long-term value.

Omnibus Equity Incentive Plan financial

"Issued pursuant to the terms of the BankUnited, Inc. 2023 Omnibus Equity Incentive Plan"

A single, company-wide plan that lets a business grant different kinds of stock-based pay — such as stock options, shares that vest over time, or other equity awards — to employees, directors and consultants. It matters to investors because it determines how much of the company can be paid out in shares, how quickly those shares enter the market, and how well employees are motivated to grow the business; think of it as a toolbox or menu for paying with ownership stakes that can dilute existing holders and affect company performance.

vest financial

"4,913 units will vest on December 31, 2026; 4,914 on December 31, 2027; and 4,913 on December 31, 2028"

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.
