restricted stock units ("RSUs") financial

"Represents the number of shares of Class A Common Stock underlying restricted stock units ("RSUs")."

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

Continuous Service financial

2019 Equity Incentive Plan financial
