"shares reported as beneficially owned by Jack Furst"
Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
irrevocable proxyregulatory
"holds an irrevocable proxy pursuant to the voting agreement"
An irrevocable proxy is a legal authorization in which a shareholder gives another person or entity the permanent right to vote their shares and cannot later take that voting permission back. It matters to investors because it locks who controls voting power on key issues—like board elections, mergers, or major policy changes—so it can change corporate control and influence the value or direction of an investment much like handing someone an unchangeable voting card.
shared voting powerfinancial
"Shared Voting Power 1,902,299.00"
Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.
dispositive powerfinancial
"Shared Dispositive Power 1,902,299.00"
Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
Class B common stockfinancial
"shares of Class B common stock beneficially owned by 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.
