beneficial owner financial

"therefore may be deemed the beneficial owner of the Class A Common Shares"

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

pecuniary interest financial

"disclaims beneficial ownership of any Class A Common Shares other than to the extent he or it may have a pecuniary interest"

Class A Common Stock financial

"Represents 16,516,955 shares of Class A Common Stock, par value $0.01 per share"
