restricted stock units ("RSUs") financial
"Constitute restricted stock units ("RSUs") for which the Reporting Person is entitled"
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 1.4500"
exercise price financial
"conversion_or_exercise_price": "1.4500""
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.
vesting financial
"100% of the RSUs shall vest on the one year anniversary of June 3, 2026"
Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
