Common Units financial
"holders have the right to exchange their common units of Medline Holdings, LP ("Common Units")"
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 Stock financial
"Shares of the Issuer's Class B common stock ("Class B Common Stock") have no economic value"
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.
