Restricted Stock Units financial

"These Restricted Stock Units vest in full on the earlier of (1) the anniversary"

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.

2020 Stock Plan financial

"pursuant to the Entegris, Inc. 2020 Stock Plan, which provides for the award"

independent directors financial

"provides for the award of Restricted Stock Units to independent directors in consideration"

Members of a company’s board who do not have significant business, family, or financial ties to the company and are not part of its management; they are chosen to provide impartial oversight of strategy, financial reporting, executive pay and risk. They matter to investors because independent directors act like an objective referee, helping ensure decisions favor shareholders’ long-term interests rather than insiders, which can strengthen trust and reduce the chance of mismanagement or conflicts of interest.
