Class B ordinary shares financial
"the Class B ordinary shares, par value $0.0001 per share, will automatically convert"
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.
Class A ordinary shares financial
"convert into Class A ordinary shares, par value $0.0001 per share, of the issuer"
Class A ordinary shares are a type of ownership stake in a company that typically grants voting rights to shareholders, allowing them to have a say in important company decisions. They often come with priority in receiving dividends or profits, making them attractive to investors seeking influence and potential income. These shares help distinguish different levels of ownership and rights within a company's stock structure.
initial business combination financial
"will automatically convert ... concurrently with or immediately following the Issuer's initial business combination"
An initial business combination is the deal in which a special-purpose acquisition company (SPAC) merges with or acquires an operating business to bring that business onto public markets. Think of the SPAC as an empty shell that raises money from investors, then uses that cash to buy a private company—this transaction turns the private company into a public one and often changes its ownership, valuation, and access to capital, so investors should watch for shifts in risk, future growth prospects, and shareholder rights.
anti-dilution rights financial
"subject to adjustment for share splits ... and certain anti-dilution rights"
private placement shares and warrants financial
"does not include 86.66 private placement shares and warrants"
private right shares financial
"and 22 private right shares to be issued to the Reporting Person"
