Private Placement Warrants financial

"acquired, at a price of $1.00 per warrant, 2,750,000 warrants (the "Private Placement Warrants") in a private placement"

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.

initial public offering financial

"Simultaneously with the consummation of the Company's initial public offering, Iron Dome Acquisition I Parent LLC acquired the warrants"

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.

beneficial ownership financial

"Mr. Norden may be deemed to have or share beneficial ownership of the securities held directly by the Sponsor"

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.

initial business combination financial

"The Private Placement Warrants will become exercisable at any time commencing 30 days after the completion of the Company'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.

pecuniary interests financial

"Mr. Norden disclaims any beneficial ownership of the reported securities other than to the extent of any pecuniary interests Mr. Norden may have therein"
