"Restricted Share Units (RSUs) issued in lieu of cash dividends"

Restricted share units (RSUs) are a form of employee pay where a company promises to give shares (or their cash value) to workers after certain conditions, usually time or performance, are met. For investors, RSUs matter because they can increase the number of shares outstanding and signal how management is being paid and incentivized—think of them as delayed bonuses that convert into ownership when vesting conditions are satisfied.

vest financial

"when the underlying shares vest"

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.
