Restricted Stock Unit financial

"Each restricted stock unit represents a contingent right to receive one share"

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.

contingent right financial

"represents a contingent right to receive one share of Arista Networks"

vesting financial

"Common Stock upon vesting"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

quarterly vest date financial

"will continue to vest at the same rate on each quarterly vest date thereafter"

derivative financial

"transaction_type": "derivative""

A derivative is a financial contract whose value depends on the price or performance of another asset or measure — for example a stock, index, interest rate, commodity, or currency. Investors use derivatives like insurance or leveraged bets to hedge risk, speculate, or gain exposure without owning the underlying asset; they can protect portfolios but also amplify losses and introduce counterparty and market risk.
