restricted stock unit financial

"upon the vesting of a time-based restricted stock unit previously granted"

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.

tax liability financial

"withheld by the Issuer to cover the tax liability upon the vesting"

Employee Stock Purchase Plan financial

"acquired pursuant to the Company's 2021 Employee Stock Purchase Plan (ESPP)"

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.

ESPP financial

"Company's 2021 Employee Stock Purchase Plan (ESPP) for the purchase period"

An Employee Stock Purchase Plan (ESPP) is a company program that lets employees buy the company’s shares at a reduced price, usually by setting aside a small portion of their pay over time. It matters to investors because it encourages employees to own part of the business—like giving staff a discounted membership— which can boost commitment and performance, while also potentially increasing the number of shares available and affecting shareholder value.
