Organization, Business Operation and Going Concern Consideration | Note 1 — Organization, Business Operation and Going Concern Consideration Horizon Space Acquisition II Corp. (the “Company”) is a newly organized blank check company incorporated in the Cayman Islands on March 21, 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 (the “Business Combination”). The Company has not selected any potential Business Combination target or initiated any substantive discussions, directly or indirectly, with any potential Business Combination prospects. The Company has selected December 31 as its fiscal year end. As of September 30, 2024, the Company had not commenced any operations. For the period from March 21, 2023(inception) through September 30, 2024, the Company’s efforts have been limited to organizational activities as well as activities related to the initial public offering. 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 (as defined below) and private placement (“Private Placement”, see Note 4). The Company’s founder and sponsor is Horizon Space Acquisition II Sponsor Corp., a Cayman Islands company (the “Sponsor”). The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through IPO and the Private Placement. On November 18, 2024, the Company consummated its initial public offering (the “IPO”) of 6,000,000 units (“Units”). Each unit consists of one ordinary share, and one right to receive one-tenth (1/10) of one ordinary share. Each ten rights entitle the holder thereof to receive one ordinary share upon the consummation of the Business Combination. The Units were sold at an offering price of $10.00 per Unit, generating total gross proceeds of $60,000,000. On November 19, 2024, the underwriter notified the Company of its exercise of the over-allotment option in full to purchase additional 900,000 Units of the Company (the “Over-Allotment Option”). As a result, on November 21, 2024,900,000 Units were sold to the underwriter at an offering price of $10.00 per Option Unit (the “Option Units” and together with the Units, collectively, the “Public Units”), generating gross proceeds of $9,000,000. Simultaneously with the consummation of the IPO and the sale of the Units, the Company consummated the private placement (“Private Placement”) of 200,000 units (the “Private Placement Units”) to the Sponsor, at a price of $10.00 per Private Placement Unit, generating total proceeds of $2,000,000, which is described in Note 4. Simultaneously with the issuance and sale of the Option Units, the Company completed a private placement sale of additional 13,500 units (the “Additional Private Units” and together with the Initial Private Units, collectively, the “Private Units”) to the Sponsor at a purchase price of $10.00 per Additional Private Unit, generating gross proceeds of $135,000. Transaction costs amounted to $1,665,262, consisting of $900,000 of underwriting commissions which was paid in cash at the closing date of the IPO, $297,045 of the Representative Shares (discussed in the below), and $468,217 of other offering costs. At the IPO date, cash of $939,635 was held outside of the Trust Account (as defined below) and is available for the payment of accrued offering costs and for working capital purposes. In conjunction with the IPO, the Company issued to the underwriter 210,000 ordinary shares for no consideration (the “Representative Shares”). 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 $297,045. In connection with the issuance and sales of the Option Units, the Company issued additional 31,500 Representative Shares to the underwriter. 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 assets held in the Trust Account (excluding interest income earned on the Trust Account that is released to the Company to pay taxes) at the time of the agreement to enter into the initial Business Combination. However, the Company will only complete such 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 it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (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 the net proceeds of the IPO and the sale of the Private Units, $10.00 per unit will be placed into a U.S.-based Trust Account (“Trust Account”) maintained by Wilmington Trust, N.A., acting as 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 which invest only in direct U.S. government treasury obligations. Except with respect to interest earned on the funds held in the Trust Account that may be released to pay the Company’s tax obligations and liquidation expenses up to $50,000, the proceeds from the IPO and the sale of the Private Units that are deposited in the Trust Account will not be released from the Trust Account until the earliest to occur of:(a) the completion of the initial Business Combination, (b) the redemption of any public shares properly submitted in connection with a shareholder vote to amend the Company’s memorandum and articles of association (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Business Combination or to redeem 100% of the Company’s public shares if the Company does not complete the Business Combination within 12 months from the closing of this IPO (or up to 18 months from the closing of this IPO if the Company extends the period of time to consummate the Business Combination by the full amount of time) or (ii) with respect to any other provision relating to shareholders’ rights or pre-initial Business Combination activity and (c) the redemption of the public shares if the Company is unable to complete the Business Combination within 12 months from the closing of this IPO (or up to 18 months from the closing of this IPO if the Company extends the period of time to consummate a Business Combination by the full amount of time), subject to applicable law. Although the Company will seek to have all vendors, including lenders for money borrowed, prospective target businesses or other entities the Company engages execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of the Company’s public shareholders, 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 public shareholders. The Company will provide its public shareholders with the opportunity to redeem all or a portion of their public shares upon the completion of the Business Combination either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The ordinary shares subject to redemption accredited to the redemption value and classified as temporary equity upon the completion of the IPO, in accordance with Financial Accounting Standard Board’s (FASB) Accounting Standards Codification (“ASC”) Topic 480“Distinguishing Liabilities from Equity.” In such case, the Company has determined that the Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and, if the Company seeks shareholder approval, a majority of the issued and outstanding shares voted are voted in favor of the Business Combination. If the Company cannot complete a Business Combination within such 12-month period (or up to 18 months from the closing of this offering if the Company extends the period of time to consummate a Business Combination by the full amount of time), unless the Company extends such period pursuant to 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 (which interest shall be net of income taxes payable, and less up to$50,000 of interest to pay liquidation 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 the Company’s remaining shareholders and Board of Directors, liquidate and dissolve, subject in each case to the Company’s 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 rights. The rights will expire worthless if the Company fails to complete a Business Combination within the 12-month time period (or up to 18 months from the closing of this offering if the Company extends the period of time to consummate a Business Combination by the full amount of time). Pursuant to the terms of the Company’s memorandum and articles of association, in order to extend the time available for the Company to consummate its initial Business Combination, the Sponsor or designees, must deposit into the Trust Account for each three months extension, $600,000, or $690,000 if the underwriter’s over-allotment option is exercised in full ($0.10 per share in either case), up to an aggregate of $1,200,000 or $1,380,000 if the underwriter’s over-allotment option is exercised in full, on or prior to the date of the applicable deadline. Going Concern Consideration As of September 30, 2024, the Company had a working capital deficit of $175,658. The Company has incurred and expects to continue to incur significant professional costs to remain as a publicly traded company and to incur significant transaction costs in pursuit of the consummation of a Business Combination. In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” management has determined that these conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plan in addressing this uncertainty is through the Working Capital Loans, as defined below (see Note 5). In addition, if the Company is unable to complete a Business Combination within the Combination Period by November 18, 2025, unless further extended, the Company’s board of directors would proceed to commence a voluntary liquidation and thereby a formal dissolution of the Company. There is no assurance that the Company’s plans to consummate a Business Combination will be successful within the Combination Period. As a result, management has determined that such additional condition also raise substantial doubt about the Company’s ability to continue as a going concern. The financial statement does not include any adjustments that might result from the outcome of this uncertainty. |
