NOTES TO PRO FROMA FINANCIAL STATEMENT

Note 1 — Closing of Over-allotment Options and Additional Private Units, and Issuance of Additional Representative Shares

The accompanying unaudited Pro Forma Balance Sheet presents the Balance Sheet of Horizon Space Acquisition II Corp. (the “Company”) as of November 18, 2024, adjusted for the closing of the underwriters’ over-allotment option and related transactions which occurred on November 21, 2024 as described below.

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.

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.

The Company also issued to the underwriter (“Representative”) 210,000 ordinary shares as part of the underwriting compensation (the “Representative Shares”) on the closing of the IPO.

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 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. In connection with the issuance and sales of the Option Units, the Company issued additional 31,500 Representative Shares to the underwriter.
