Columbus Circle Capital Corp II 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, between the United States, Israel and Iran and others in the Middle East, and Southwest Asia or other armed hostilities. 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 Founder Shares, Private Placement Units (and their underlying securities) and Units that may be issued upon conversion of working capital loans (and their underlying securities), if any, and any Class A Ordinary Shares issuable upon conversion of the Founder Shares and any Class A Ordinary Shares held by the Initial Shareholders at the completion of the Initial Public Offering or acquired prior to or in connection with the initial Business Combination, will be entitled to registration rights pursuant to a registration rights agreement to be signed prior to or on the effective date of the registration statement for the Initial Public Offering. These holders will be entitled to make up to three demands and have piggyback registration rights. The Company will bear the expenses incurred in connection with the filing of any such registration statements. CCM and Clear Street 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, CCM and Clear Street may participate in a piggyback registration only during the seven-year period beginning on the effective date of the Initial Public Offering.

Underwriters’ Agreement

The underwriters had a 45-day option from the date of the Initial Public Offering to purchase up to an additional 3,000,000 Units to cover over-allotments, if any. On February 12, 2026, the underwriters exercised their over-allotment option in full, purchasing 3,000,000 Units.

The underwriters were entitled to a cash underwriting discount of 2.00% of the gross proceeds of the Initial Public Offering, excluding overallotment option, or $4,000,000 which was paid upon the closing of the Initial Public Offering.

Business Combination Marketing Agreement

The Company engaged CCM and Clear Street as advisors in connection with the Business Combination to assist in holding meetings with shareholders to discuss potential Business Combination and the target business’ attributes, introduce the Company to potential investors that are interested in purchasing securities and assist the Company with press releases and public filings in connection with the Business Combination. The Company will pay CCM and Clear Street a cash fee for such services upon the consummation of the initial Business Combination in an amount equal to $9,800,000 in the aggregate. The amount of the fee payable will be based on the amount of funds remaining in the Trust Account after redemptions of Public Shares and will be paid to the underwriters only upon the completion of an initial Business Combination. As a result, CCM and Clear Street will not be entitled to such fee unless the Company consummates its initial Business Combination.
