Business Description

Note 1 — Description of Organization and Business Operations Black Hawk Acquisition Corporation (the “Company”) is a blank check company incorporated under the laws of the Cayman Islands with limited liability on September 28, 2023. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (“Business Combination”). The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of November 30, 2025, the Company had not commenced any operations. All activities through November 30, 2025 are related to the Company’s formation and the initial public offering (“IPO” as defined below), and subsequent to the IPO, identifying a target company for an initial 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 interest income from the proceeds derived from the IPO. The Company has selected November 30 as its fiscal year end. The Company’s sponsor is Black Hawk Management LLC (the “Sponsor”), a Delaware limited liability company. The registration statement for the Company’s IPO became effective on March 20, 2024. On March 22, 2024, the Company consummated the IPO of 6,900,000 units (which does not include the exercise of the over-allotment option by the underwriters in the IPO) at an offering price of $ 10.00 per unit (the “Public Units’), generating gross proceeds of $ 69,000,000 . Simultaneously with the IPO, the Company sold to its Sponsor 235,500 units at $ 10.00 per unit (the “Private Units”) in a private placement generating total gross proceeds of $ 2,355,000 , which is described in Note 4. Transaction costs amounted to $ 4,309,493 , consisted of $ 690,000 cash underwriting, $ 2,415,000 deferred underwriting fees (payable only upon completion of a Business Combination), $ 690,000 issuance of representative shares and $ 514,493 other offering costs. Upon the closing of the IPO and the private placement on March 22, 2024, a total of $ 69,345,000 was placed in a trust account (the “Trust Account”) maintained by Continental Stock Transfer & Trust Company as a trustee and will be invested only in U.S. government treasury bills with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”), and that invest only in direct U.S. government treasury obligations. These funds will not be released until the earlier of the completion of the initial Business Combination and the liquidation due to the Company’s failure to complete a Business Combination within the applicable period of time. The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the Company’s public shareholders. In addition, interest income earned on the funds in the Trust Account may be released to the Company to pay its income or other tax obligations. With these exceptions, expenses incurred by the Company may be paid prior to a business combination only from the net proceeds of the IPO and private placement not held in the Trust Account. Pursuant to Nasdaq listing rules, the Company’s initial Business Combination must occur with one or more target businesses having an aggregate fair market value equal to at least 80% of the value of the funds in the Trust account (excluding any deferred underwriting discounts and commissions and taxes payable on the income earned on the Trust Account), which the Company refers to as the 80 % test, at the time of the execution of a definitive agreement for its initial Business Combination, although the Company may structure a Business Combination with one or more target businesses whose fair market value significantly exceeds 80% of the trust account balance. If the Company is no longer listed on Nasdaq, it will not be required to satisfy the 80% test.…
