5 terms

private units financial

"Reflects the 220,000 private units owned by Burtech Sponsor II LLC"

redeemable warrant financial

"and one redeemable warrant, with each whole warrant entitling the holder"

A redeemable warrant is a financial tool that gives its holder the right to buy shares of a company at a fixed price within a certain period. If the holder chooses to do so, the company can buy back or cancel the warrant before it expires, often to encourage investment or manage share issuance. For investors, it provides an option to potentially buy shares at a favorable price while offering some flexibility for the issuing company.

initial business combination financial

"will become exercisable 30 days after the completion of 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.

over-allotment option financial

"after the surrender 514,286 Class B ordinary shares because the underwriter did not exercise its over-allotment option"

An over-allotment option is a special agreement that allows underwriters to sell more shares than initially planned if demand is high. Think of it like a retailer offering extra units of a popular product to meet additional customer interest. This option helps ensure the full sale is completed and can also give investors extra shares if they want more.

aggregate purchase price financial

"at $10.00 per unit for an aggregate purchase price of $2,200,000"

The aggregate purchase price is the total amount a buyer pays to acquire a company, assets or securities, including the headline payment plus any assumed debt, fees, taxes and contractually required adjustments. It matters to investors because it shows the true cost of a deal and how much value must be realized after the sale — like knowing the full price of a house once you add closing costs, repairs and outstanding mortgage obligations.
