Restricted Stock Units ("RSUs") financial

"Represents an annual equity retainer of Restricted Stock Units ("RSUs") vesting on July 1, 2027"

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.
