restricted stock unit financial

"These shares represent a restricted stock unit award granted to the reporting person"

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.

employee stock purchase plan financial

"Includes 83 shares acquired in non-reportable transactions through Coherent Corp.'s employee stock purchase plan"

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

quarterly installments financial

"remaining two-thirds (2/3) of the restricted stock units will vest in eight equal quarterly installments"
