5 terms
Common Unitsfinancial
"holders have the right to exchange their Common Units for shares of the Class A Common Stock"
Common units are the basic ownership stakes in a company, limited partnership, or trust that function like common stock: they give holders a claim on profits and often voting rights. Think of them as the ordinary seats at a table—the most directly affected by the business’s success or failure, so they typically offer higher upside but carry greater risk than preferred claims or creditors, which matters to investors evaluating potential return and safety.
Class B Common Stockfinancial
"Shares of the Class B Common Stock have no economic value and have one vote per share"
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.
beneficially ownregulatory
"As of March 31, 2026, the Reporting Persons may be deemed to beneficially own an aggregate"
Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.
Rule 13d-3regulatory
"calculated pursuant to Rule 13d-3 of the Act"
Rule 13d-3 defines who is treated as the beneficial owner of a company’s shares for U.S. securities disclosure rules — essentially anyone who has the power to vote or direct how shares are voted, or the power to buy or sell them, even if they don’t hold the certificates. For investors this matters because crossing certain ownership thresholds triggers public filing and disclosure obligations and signals potential control or influence, much like having the keys to a car implies you can drive it even if it’s registered to someone else.
exchange agreementlegal
"pursuant to the terms of an exchange agreement, dated as of December 16, 2025"
A written deal in which two parties agree to swap assets, securities or obligations under set terms—think of it as a formal swap or trade contract. For investors it matters because such agreements can change who owns what, alter a company’s capital structure, affect future cash flows or dilute existing shares, and therefore influence value and risk in a straightforward, contract-driven way.
