Restricted Stock Unit financial
"These restricted stock units (RSUs) were acquired pursuant to an award under the Veeco Instruments 2019 Stock Incentive Plan"
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.
Veeco Instruments 2019 Stock Incentive Plan financial
"These restricted stock units (RSUs) were acquired pursuant to an award under the Veeco Instruments 2019 Stock Incentive Plan"
beneficially owned financial
"a corresponding revision to the total amount of securities beneficially owned in Table I"
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.
