Restricted Stock Units financial

"Restricted Stock Units that vest as follows: 25% of shares subject to the award will vest on May 20, 2027"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

Employee Stock Option (right to buy) financial

"Employee Stock Option (right to buy) with 3,789 shares underlying common stock"

exercise price financial

"conversion_or_exercise_price: "71.1300" for the employee stock option grant"

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.

vest financial

"25% of shares subject to the award will vest on May 20, 2027, and on each May 20th thereafter"

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.
