On February 9, 2026, Cambridge Acquisition Corp. (the “Company”) consummated its initial public offering (“IPO”), which consisted of 23,000,000 units (the “Units”), including 3,000,000 Units issued pursuant to the exercise in full by the underwriters of their over-allotment option. Each Unit consists of one Class A ordinary share, $0.0001 par value (“Class A Ordinary Share”) and one-third of one redeemable warrant of the Company (each, a “Warrant”), with each whole Warrant entitling the holder thereof to purchase one Class A Ordinary Share for $11.50 per share (subject to adjustment). The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $230,000,000.

Simultaneously with the closing of the IPO, the Company consummated a private placement (the “Private Placement”) of an aggregate of 495,500 units (the “Private Units”) to Cambridge Sponsor LLC, the Company’s sponsor, at a price of $10.00 per Private Unit, generating total proceeds of $4,955,000. Each Private Unit consists of one Class A Ordinary Share and one-third of one redeemable Warrant, with each whole Warrant entitling the holder thereof, to purchase one Class A Ordinary Share for $11.50 per share (subject to adjustment).

A total of $230,000,000, or $10.00 per Unit, comprised of the net proceeds from the IPO (which amount includes up to $8,050,000 of the underwriter’s deferred discount) and proceeds of the sale of the Private Units, was placed in a U.S.-based trust account maintained by Continental Stock Transfer & Trust Company, acting as trustee.

An audited balance sheet as of February 9, 2026 reflecting the receipt of the proceeds from the IPO and the Private Placement has been issued by the Company and is included as Exhibit 99.1 to this Current Report on Form 8-K.
