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.

Option (Right to Buy financial

"security_title: "Option (Right to Buy)" for derivative holdings linked to Class A Common Stock."

Class A Common Stock financial

"underlying_security_title: "Class A Common Stock" for options and non-derivative shares."

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.
