Class A Common Stock financial
"Consists of (i) 471,774 shares of Class A Common Stock and 8,963,719 Common Units"
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.
Class B Common Stock financial
"and a corresponding number of shares of Class B Common Stock held by GM Enterprises, LLC"
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.
Common Units financial
"The Common Units of X-Energy Reactor Company, LLC may be redeemed for shares"
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.
dispositive power financial
"Dr. Kamal Ghaffarian has sole voting and dispositive power with respect to securities"
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.
pecuniary interest financial
"disclaims beneficial ownership of such securities except to the extent of his pecuniary interest therein"
