restricted stock units financial

"Shares are restricted stock units issued to the Reporting Person"

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.

"pursuant to the OSI Systems, Inc. Amended and Restated 2012 Incentive Award Plan"

performance targets financial

"Vesting and amount of shares are subject to achievement of performance targets"

beneficially owned financial

"The amount of securities beneficially owned following the reported transaction"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
