restricted stock units financial

"These restricted stock units each represent a contingent right to receive one share of Fiserv, Inc. common stock."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

contingent right financial

"These restricted stock units each represent a contingent right to receive one share of Fiserv, Inc. common stock."

vest financial

"The restricted stock units vest 100% on the earlier of the first anniversary of the grant date or immediately prior to the first annual meeting of shareholders."

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.

annual meeting of shareholders financial

"Immediately prior to the first annual meeting of shareholders after the grant date."

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.
