Restricted Stock Units financial

"Each restricted stock unit represents 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

"represents a contingent right to receive one share of HLIT common stock"

vesting financial

"will vest each three months thereafter, so as to be 100% vested"

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.

RSU Vesting Commencement Date financial

"100% vested on the third anniversary of the RSU Vesting Commencement Date"
