par value financial

"Ordinary shares, par value $0.0001 per share"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.

initial business combination financial

"upon the consummation of an 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.
