Restricted Stock Unit financial
"Each restricted stock unit represents a contingent right to receive one share of Arista Networks, Inc. Common Stock upon vesting."
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.
