Item 4.01 Changes in Registrant’s Certifying Accountant.

On January 22, 2026, Horizon Space Acquisition I Corp., a Cayman Islands exempted company (the “Company” or “HSPO”), upon the approval of the board of directors of the Company (the “Board”) and the audit committee of the Board (the “Audit Committee”), dismissed UHY LLP (“UHY”), the former independent registered public accounting firm of the Company and appointed TAAD LLP (ID: 5854) (“TAAD”) to serve as its independent registered public accounting firm for the fiscal year ended December 31, 2025.

UHY’s reports on the Company’s financial statements for the fiscal years ended December 31, 2023 and 2024 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles. Furthermore, during the fiscal years ended December 31, 2023 and 2024 and the subsequent interim period through January 22, 2026, there were no disagreements with UHY on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of UHY, would have caused UHY to make reference to the subject matter of the disagreements in connection with its reports on the Company’s financial statements for such years. Also during this time, there were no “reportable events,” as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company provided UHY with a copy of the above disclosure and requested that UHY furnish the Company with a letter addressed to the U.S. Securities and Exchange Commission stating whether or not it agrees with the above statements. A copy of the UHY’s letter is filed as Exhibit 16.1 to this Current Report on Form 8-K. 

During the two most recent fiscal years and any subsequent interim periods prior to the engagement of TAAD, neither the Company, nor someone on behalf of the Company, has consulted TAAD regarding (i) the application of accounting principles to any specified transaction, either completed or proposed or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company that TAAD concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue, or (ii) any matter that was either the subject of a “disagreement,” as defined in Item 304(a)(1)(iv) of Regulation S-K, or a “reportable event,” as defined in Item 304(a)(1)(v) of Regulation S-K, or any other matters set forth in Item 304(a)(2)(i) and (ii) of Regulation S-K.
