restricted stock units ("RSUs") financial
"Represents the issuance of restricted stock units ("RSUs"). Each RSU represents a contingent right"
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) with an exercise price of 60.9000"
vest financial
"The RSUs vest over three years, with 1/3 vesting on May 20, 2027"
A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.
exercisable financial
"The option shares vest and become exercisable over three years"
exercise price financial
"conversion_or_exercise_price": "60.9000""
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.
