restricted stock units ("RSUs") financial

"Represents restricted stock units ("RSUs") granted under the Sky Harbour Group Corporation 2022 Incentive Award Plan."

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.

"The RSUs vest in installments ... provided the reporting person remains in service through the applicable vesting date."
