Cambridge Acquisition Corp. Commitments Disclosure

Note 6 — Commitments and Contingencies

Risks and Uncertainties

The Company’s ability to complete an initial Business Combination may be adversely affected by various factors, many of which are beyond the Company’s control. The Company’s ability to consummate an initial Business Combination could be impacted by, among other things, changes in laws or regulations, downturns in the financial markets or in economic conditions, inflation, fluctuations in interest rates, increases in tariffs, supply chain disruptions, declines in consumer confidence and spending, public health considerations, and geopolitical instability, such as the military conflicts in Ukraine and the Middle East. The Company cannot at this time predict the likelihood of one or more of the above events, their duration or magnitude or the extent to which they may negatively impact the Company’s ability to complete an initial Business Combination.

Registration Rights

The holders of the Founder Shares, Private Placement Units and the Class A ordinary shares underlying the warrants contained in such Private Placement Units and Private Placement Units that may be issued upon conversion of the Working Capital Loans will have

registration rights to require the Company to register for resale of any of the Company’s securities held by them and any other securities of the Company acquired by them prior to the consummation of the initial Business Combination pursuant to a registration rights agreement signed on the effective date of the Initial Public Offering. The holders of these securities are entitled to make up to three demands, excluding short-from demands, that the Company registers such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. Notwithstanding anything to the contrary, the underwriters may only make a demand on one occasion and only during the five-year period beginning on the effective date of the Initial Public Offering. In addition, the underwriters may participate in a piggyback registration only during the seven-year period beginning on the effective date of the Initial Public Offering. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriters’ Agreement

The Company granted the underwriters a 45-day option from the date of the Initial Public Offering to purchase up to an additional 3,000,000 Public Units to cover over-allotments, if any. On February 9, 2026, the underwriters exercised their over-allotment option, closing on the 3,000,000 additional Public Units simultaneously with the Initial Public Offering.

The underwriters were paid a cash underwriting discount of $3,105,000 upon the closing of the Initial Public Offering. Additionally, the underwriters were entitled to a deferred underwriting fee of $8,050,000 in the aggregate, payable to the representative on behalf of the underwriters only upon the consummation of an initial Business Combination.
