restricted stock units financial

"These restricted stock units each represent a contingent right to receive one share"

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

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

vest 100% financial

"The restricted stock units vest 100% on the earlier of: (i) the first anniversary"

grant date financial

"on the earlier of: (i) the first anniversary of the grant date"

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.

annual meeting of shareholders financial

"or (ii) 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.
