Note 1 — Organization, Business Operation and Going Concern Consideration

Columbus Acquisition Corp (the “Company”) is a blank check company incorporated in the Cayman Islands on January 18, 2024. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or similar business combination with one or more businesses or entities (the “Business Combination”). The Company’s efforts to identify a prospective target business will not be limited to a particular industry or geographic location. The Company does not have any specific business combination under consideration. The Company’s significant ties to China would make it a less attractive partner to a non-China-based target company and such perception may potentially limit or negatively impact our search for an initial business combination; or may therefore make it more likely for the Company to consummate a business combination with a company being based in or having the majority of the company’s operations in China. The Company has selected December 31 as its fiscal year end.

As of June 30, 2025, the Company had not commenced any operations. For the period from January 18, 2024 (inception) through June 30, 2025, the Company’s efforts had been limited to organizational activities as well as activities related to completing the initial public offering (“IPO”) described below, and subsequent to the IPO, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generate non-operating income in the form of dividend and/or interest income from the proceeds derived from the IPO and sale of Private Placement Units (as defined below).

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the IPO and the sale of the Private Placements Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully.

The Company’s founder and sponsor is Hercules Capital Management VII Corp, a British Virgin Islands company (the “Sponsor”). The Company’s ability to commence operations was contingent upon obtaining adequate financial resources through the IPO (see Note 3) and a Private Placement (as defined below) to the initial shareholder (see Note 4).

On January 24, 2025, the Company consummated its IPO of 6,000,000 units (“Units”). Each Unit consists of one ordinary share, $0.0001 par value per share, and one right to receive of one-seventh of one ordinary share upon the completion of the initial Business Combination. The Units were sold at an offering price of $10.00 per Unit, generating total gross proceeds of $60,000,000. The Company has also granted the underwriters a 45-day option to purchase up to an additional 900,000 Units to cover over-allotments, if any (see Note 3).

Simultaneously with the consummation of the IPO and the sale of the Units, the Company consummated the private placement (“Private Placement”) of 234,290 units (the “Private Placement Units”) to the Sponsor, at a price of $10.00 per Private Placement Unit, generating total proceeds of $2,342,900, which is described in Note 4.

Transaction costs amounted to $1,587,534 consisting of $900,000 of underwriting commissions which were paid in cash at the closing date of the IPO, $361,000 of the Representative Shares (discussed below), and $326,534 of other offering costs. At the IPO date, cash of $1,007,756 (which is net of funds used to repay the then outstanding balance of the Promissory Note described in Note 5) was held outside of the Trust Account (as defined below) and is available for working capital purposes.

In conjunction with the IPO, the Company issued to the underwriter 210,000 ordinary shares (the “Representative Shares”), which are nonredeemable. The fair value of the Representative Shares accounted for as compensation under Accounting Standards Codification (“ASC”) 718, “Compensation – Stock Compensation” (“ASC 718”) is included in the offering costs. The estimated fair value of the Representative Shares as of the IPO date totaled $361,000. 

The Company’s initial Business Combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the balance in the Trust Account (as defined below), (less any taxes payable on the income earned on the Trust Account) at the time of execution of the definitive agreement in connection with its initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for the post-transaction company not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). The Company does not believe that its anticipated principal activities will subject the Company to the Investment Company Act. There is no assurance that the Company will be able to complete a Business Combination successfully.

Upon the closing of the IPO, management has agreed that at least $10.00 per public share underlying Units sold in the IPO will be held in a U.S.-based trust account (“Trust Account”). The funds held in the Trust Account will be invested only in U.S. government treasury bills with a maturity of 185 days or less, or in money market funds meeting the applicable conditions of Rule 2a-7 promulgated under the Investment Company Act which invest solely in direct U.S. government treasury securities, or in an interest bearing or non-interest-bearing demand deposit account. Except with respect to dividend and/or interest earned on the funds held in the Trust Account that may be released to the Company to pay the Company’s tax obligation, if any, the proceeds from the IPO and the sale of the Private Placement Units that are deposited and held in the Trust Account will not be released from the Trust Account until the earliest to occur of (i) the completion of the Company’s initial Business Combination, (ii) the redemption of any public shares properly tendered in connection with a shareholder vote to amend the Company’s Amended and Restated Memorandum and Articles of Association to (A) modify the substance or timing of obligation to redeem 100% of the Company’s public shares if the Company does not complete the Company’s initial Business Combination by January 22, 2026 (unless the Company extends such period by amending its Amended and Restated Memorandum and Articles of Association) or (B) with respect to any other provision relating to shareholders’ rights or pre-business combination activity and (iii) the redemption of all of the Company’s public shares if the Company is unable to complete its initial business combination by January 22, 2026, subject to applicable law. In no other circumstances will a public shareholder have any right or interest of any kind to or in the Trust Account.

The Company will provide its public shareholders with the opportunity to redeem all or a portion of their public shares upon either (i) the completion of the initial Business Combination, (ii) if the Company is unable to complete the initial Business Combination within the prescribed combination period, subject to applicable law, or (iii) a shareholder vote to amend the Amended and Restated Memorandum and Articles of Association (A) to modify the substance or timing of the obligation to redeem 100% of the public shares if the Company has not consummated an initial Business Combination within the prescribed combination period or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity.

The Company has determined not to consummate any Business Combination unless the Company has net tangible assets of at least $5,000,001 upon such consummation in order to avoid being subject to Rule 419 promulgated under the Securities Act. However, if the Company seeks to consummate an initial Business Combination with a target business that imposes any type of working capital closing condition or requires the Company to have a minimum amount of funds available from the Trust Account upon consummation of such initial Business Combination, its net tangible asset threshold may limit the Company’s ability to consummate such initial Business Combination (as the Company may be required to have a lesser number of shares redeemed) and may force the Company to seek third party financing which may not be available on terms acceptable to the Company or at all. As a result, the Company may not be able to consummate such an initial Business Combination and the Company may not be able to locate another suitable target within the applicable time period, if at all.

The Company will have until January 22, 2026 to complete its initial Business Combination. If the Company is unable to complete its initial Business Combination by January 22, 2026, unless the Company extends such period by amending its Amended and Restated Memorandum and Articles of Association, the Company will: (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of its remaining shareholders and its board of directors, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to public rights or private placement rights, which will expire worthless if the Company fails to complete its initial Business Combination by January 22, 2026, unless the Company extends such period by amending and restating its Amended and Restated Memorandum and Articles of Association. 

Going Concern Consideration

As of June 30, 2025, the Company had $761,463 cash and a working capital of $719,917. The Company has incurred and expects to continue to incur significant costs to remain as a publicly traded company and to incur significant transaction costs in pursuit of the consummation of a Business Combination. The Company does not believe it will need to raise additional funds in order to meet the expenditures required for operating its business. However, if the Company’s estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, the Company may have insufficient funds available to operate its business prior to the initial Business Combination. Moreover, the Company may need to obtain additional financing either to complete its Business Combination or because it becomes obligated to redeem a significant number of the Company’s public shares upon completion of its Business Combination, in which case the Company may issue additional securities or incur debt in connection with such Business Combination.

In connection with the Company’s assessment of going concern considerations in accordance with ASC Subtopic 205-40, Presentation of Financial Statements - Going Concern, the Company may need to raise additional capital through loans or additional investments from its Sponsor, shareholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all.

The Company’s liquidity condition raises substantial doubt about the Company’s ability to continue as a going concern for a period of time within one year after the date that the accompanying unaudited condensed financial statements are issued. Management plans to address this uncertainty through seeking new financing to complete a Business Combination. If a Business Combination is not consummated by the end of the Combination Period, currently January 22, 2026, and the Combination Period is not extended, there will be a mandatory liquidation and subsequent dissolution of the Company, which also raises substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after the Combination Period. The Company intends to complete the initial Business Combination before the end of the Combination Period. However, there can be no assurance that the Company will be able to consummate any Business Combination by the end of the Combination Period.

Risks and Uncertainties

Various social and political circumstances in the U.S. and around the world (including rising trade tensions between the U.S. and China, and other uncertainties regarding actual and potential shifts in the U.S. and foreign, trade, economic and other policies with other countries), may contribute to increased market volatility and economic uncertainties or deterioration in the U.S. and worldwide.

As a result of these circumstances and the ongoing Russia/Ukraine, Hamas/Israel conflicts and/or other future global conflicts, the Company’s ability to consummate a Business Combination, or the operations of a target business with which the Company ultimately consummates a Business Combination, may be materially and adversely affected. In addition, the Company’s ability to consummate a transaction may be dependent on the ability to raise equity and debt financing which may be impacted by these events, including as a result of increased market volatility, or decreased market liquidity in third-party financing being unavailable on terms acceptable to the Company or at all. The impact of this action and related sanctions on the world economy and the specific impact on the Company’s financial position, results of operations and/or ability to consummate a Business Combination are not yet determinable. The financial statements do not include any adjustments that might result from the outcome of these uncertainties.
