Restricted Stock Unit financial

"Each Restricted Stock Unit (RSU) represents a contingent right to receive one share of Cohu, Inc. Common Stock upon vesting."

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

contingent right financial

"Each Restricted Stock Unit (RSU) represents a contingent right to receive one share of Cohu, Inc. Common Stock upon vesting."

Annual Meeting of Stockholders financial

"The RSUs vest on the earlier to occur of (i) the one-year anniversary of the date of grant or (ii) the next Cohu, Inc. Annual Meeting of Stockholders"

vesting financial

"immediately upon the vesting date (assuming continued service on the Board of Directors)."

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
