restricted stock units financial

"Represents Ouster, Inc. (the "Company") restricted stock units ("RSUs")."

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.

RSUs financial

"Each RSU represents a contingent right to receive one share"

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

vesting financial

"The RSUs vest in quarterly installments through the earlier of June 17, 2027"

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.

contingent right financial

"Each RSU represents a contingent right to receive one share"

annual meeting of stockholders financial

"through the earlier of June 17, 2027 or the Company's next annual meeting of stockholders"
