Iron Dome Acquisition I Corp. Raises $150 Million in Unit IPO, Sets Nasdaq Listing for May 15

Key Points

  • Iron Dome Acquisition I Corp. sold 15 million units at $10 per unit, raising $150 million.
  • Units consist of one Class A ordinary share and one-half of a redeemable warrant; whole warrants can be exercised at $11.50 per share, subject to adjustments.
  • Trading of units is expected to begin on the Nasdaq Global Market under IDACU on May 15, 2026; separate trading for shares and warrants will use IDAC and IDACW.
  • Santander is the sole book-running manager and underwriters have a 45-day option to purchase up to 2.25 million additional units to cover over-allotments.

Iron Dome Acquisition I Corp., a special purpose acquisition company formed to pursue a business combination, has completed the pricing of its initial public offering, selling 15 million units at $10.00 apiece for gross proceeds of $150 million.

The units are expected to start trading on the Nasdaq Global Market under the ticker symbol "IDACU" on May 15, 2026. Each unit comprises one Class A ordinary share together with one-half of a redeemable warrant. When and if the securities begin separate trading, the company said the Class A ordinary shares will trade under "IDAC" and the warrants will trade as "IDACW."

Each whole warrant entitles the holder to acquire one Class A ordinary share at a purchase price of $11.50 per share, subject to customary adjustments. The offering documentation also notes that the securities’ trading will transition to separate listings for shares and warrants after an initial period.

The offering is scheduled to close on May 18, 2026, provided customary closing conditions are met. Santander is serving as the sole book-running manager on the deal. To cover potential over-allotments, the company granted the underwriters a 45-day option to buy up to 2.25 million additional units.

Iron Dome Acquisition I Corp. said it was organized to seek a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more operating companies. The search will focus on businesses in cybersecurity, defense technology, artificial intelligence and data infrastructure.

According to the company announcement, the U.S. Securities and Exchange Commission declared the registration statement relating to the securities effective on May 14, 2026.


Context and next steps

With the units priced and the SEC filing declared effective, the immediate milestones are the listing on Nasdaq and the anticipated closing date. The over-allotment option provides the underwriters the flexibility to expand the size of the issuance if demand warrants it.

The company’s stated sector focus points to potential deal activity in areas where technology, defense and data services intersect. Beyond the listing and closing, progress toward a qualifying business combination will determine the SPAC’s longer-term trajectory.

Risks

  • The offering is scheduled to close on May 18, 2026, but is conditioned on customary closing requirements - if those conditions are not satisfied the closing may be delayed or not occur; this affects the capital markets and SPAC transaction processes.
  • The company has an over-allotment option extending 45 days for up to 2.25 million additional units, introducing uncertainty about final dilution and capital available to pursue a business combination; this is relevant to potential investors in the IPO and future deal counterparties.
  • Iron Dome Acquisition I Corp. has defined a target search focus on cybersecurity, defense technology, artificial intelligence and data infrastructure, but pursuing a qualifying business combination in those sectors carries the usual execution and market risks typical for SPACs and the specific industries mentioned.
