restricted stock units ("RSUs") financial
"Represents the issuance of 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.

Stock Option (Right to Buy) financial
"Stock Option (Right to Buy) with an exercise price of $60.90."
vest over three years financial
"The RSUs vest over three years, with 1/3 vesting on May 20, 2027."
exercise price financial
"The option shares have a $60.90 exercise price."
The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
