restricted stock units financial
"The Reporting Person was granted restricted stock units ("RSUs"), each of which represents a contingent right to receive one (1) 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.
RSUs financial
"The Reporting Person was granted restricted stock units ("RSUs"), each of which represents a contingent right to receive one (1) 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.
contingent right financial
"each of which represents a contingent right to receive one (1) share of ONTO Common Stock"
vest financial
"100% of the shares of Common Stock subject to the RSU vest one (1) year from the grant date"
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.
