Class B ordinary shares financial
"Represents 6,800,000 Class B ordinary shares held directly by the Sponsor and 100,000 Class B ordinary shares held directly by CGC III Sponsor DirectorCo LLC"
Class B ordinary shares are a type of ownership stake in a company that typically come with different voting rights or privileges compared to other share classes. For investors, they represent a way to hold part of the company’s value and influence its decisions, often with fewer voting rights than Class A shares. Understanding these shares helps investors assess their level of control and potential returns within a company.
private placement warrants financial
"Represents 4,400,000 private placement warrants held directly by the Sponsor."
Private placement warrants are tradable coupons given directly to a limited group of investors that let the holder buy a company's shares at a fixed price before a set expiration date. They matter to investors because they can provide extra upside if the stock rises and give companies a way to raise money outside a public offering, but they also can increase the number of shares outstanding (dilution) and therefore affect share value and investor returns.
beneficial ownership financial
"thus to share beneficial ownership of such securities. Mr. Yu disclaims beneficial ownership of such securities"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
dispositive control financial
"may be deemed to share voting and dispositive control over the securities held by Pangaea"
pecuniary interest financial
"disclaims beneficial ownership of such securities except to the extent of its or his pecuniary interest therein."
