restricted stock units financial
"Grant of shares upon vesting of restricted stock units."
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.
Stock Options (right to buy) financial
"security_title": "Stock Options (right to buy)""
exercise price financial
"conversion_or_exercise_price": "0.5149""
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.
annual meeting of stockholders financial
"earlier of the date immediately prior of the 2027 annual meeting of stockholders"
