restricted stock units financial

"upon the vesting of restricted stock units to satisfy the Reporting Person's tax"

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.

tax withholding obligations financial

"withheld by the Issuer upon the vesting of restricted stock units to satisfy the Reporting Person's tax withholding obligations"

employee stock purchase plan financial

"includes 49.66 shares acquired by the Reporting Person under Dorman'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.
