Restricted Stock Units financial
"These Restricted Stock Units were granted to the Reporting Person on June 30, 2026 and vested on July 1, 2026."
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.
Class B Common Stock financial
"The shares of Class B Common Stock are convertible into shares of Class A Common Stock at the option of the Reporting Person."
A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.
Option (Right to Buy) financial
"Option (Right to Buy) with an exercise price of 68.4000 and expiration date of 2032-04-04."
convertible financial
"are convertible into shares of Class A Common Stock at the option of the Reporting Person"
A convertible is a type of investment that starts as a loan or preferred stake (like a bond or preferred share) but can be exchanged for common shares of the company at a set price or under certain conditions. It matters to investors because it offers a mix of steady income and downside protection like a loan, plus the upside of stock ownership if the company does well—similar to holding a coupon that you can trade for a full ticket if the event becomes valuable.
exercise price financial
"conversion_or_exercise_price of 68.4000 and 41.8000 for options on Class A Common Stock"
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.
