6 terms

beneficially owned financial

"Aggregate amount beneficially owned by each reporting person 10,442,143.00"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

initial public offering financial

"the Issuer completed its initial public offering ("IPO") of 17,250,000 units"

An initial public offering (IPO) is when a private company first sells its shares to the public and becomes a stock-listed company. It matters because it allows the company to raise money from a wide range of investors, helping it grow, while giving early shareholders a way to sell some of their ownership.

redeemable warrant financial

"one redeemable warrant to purchase one Class A ordinary share at a price of $11.50 per share"

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.

business combination financial

"will automatically convert into Class A ordinary shares concurrently with or immediately following the consummation of the Issuer's initial business combination"

A business combination happens when two or more companies join together to operate as one, like two friends merging their teams into a single group. This is important because it can change how companies grow, compete, and make money, often making them bigger and more powerful in the market.

private placement financial

"The private units were sold in a private placement that closed simultaneously with the closing of the IPO"

A private placement is a sale of securities directly to a selected group of investors, typically institutions or accredited investors, instead of through a public offering. It lets a company raise money faster and with fewer regulatory steps; for existing shareholders it matters because the newly issued shares, often sold at a discount, increase the share count and can dilute their ownership.

dispositive power financial

"Sole Dispositive Power 10,442,143.00"

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.
