Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

Pursuant to the amendment to the amended and restated memorandum and articles of association approved in the extraordinary general meeting held on February 13, 2026 (the “Charter Amendment”) of Horizon Space Acquisition II Corp., a Cayman Islands exempted company (the “Company”), the Company currently has until February 18, 2026 to complete its initial business combination. However, the Company may extend the period of time to consummate a business combination up to twelve times, each by an additional one-month extension, up to February 18, 2027, subject to Horizon Space Acquisition II Sponsor Corp., a Cayman Islands company, the sponsor of the Company (the “Sponsor”) and/or its designee, depositing the lesser of (i) $50,000 for all remaining public shares and (ii) $0.033 for each remaining public share (the “Extension Fee”) into the trust account of the Company (the “Trust Account”).

On or about February 18, 2026, an aggregate of $50,000 of the Extension Fee was deposited into the Trust Account for the Company’s public shareholders (the “Extension Payment”) by Mr. William Wang (the “Payee”), which enables the Company to extend the period of time it has to consummate its initial business combination by one month from February 18, 2026 to March18, 2026 (the “Extension”). The Extension is the first of the twelve Extensions permitted pursuant to the Charter Amendment. Mr. William Wang is the Chief Executive Officer of SL BIO Ltd., a Cayman Islands exempted company limited by shares (“SL Bio”). On May 9, 2025, the Company, SL Bio, SL Science Holding Limited, a Cayman Islands exempted company limited by shares (“PubCo”), CW Mega Limited, a Cayman Islands exempted company limited by shares (“Merger Sub I”), and WW Century Limited, a Cayman Islands exempted company limited by shares (“Merger Sub II”), entered into a business combination agreement, pursuant to which, among other things, (i) Merger Sub I will merge with and into the Company, with the Company as the surviving entity and a wholly-owned subsidiary of PubCo (the “First Merger”), and (ii) following the First Merger, Merger Sub II will merge with and into SL Bio, with SL Bio as the surviving entity and a wholly-owned subsidiary of PubCo.

In connection with the Extension Payment, on February 18, 2026, the Company issued an unsecured promissory note of $50,000 (the “Note”) to the Payee.

The Note bears no interest and is payable in full upon the earlier to occur of (i) the consummation of the Company’s business combination or (ii) the date of expiry of the term of the Company (the “Maturity Date”). The following shall constitute an event of default: (i) a failure to pay the principal within five business days of the Maturity Date; (ii) the commencement of a voluntary or involuntary bankruptcy action, (iii) the breach of the Company’s obligations thereunder; (iv) any cross defaults; (v) an enforcement proceedings against the Company; and (vi) any unlawfulness and invalidity in connection with the performance of the obligations thereunder, in which case the Note may be accelerated.

The Payee has the right, but not the obligation, to convert the Note, in whole or in part, respectively, into private units (the “Units”) of the Company, each consisting of one ordinary share, par value $0.0001 per share (the “Ordinary Share”), and one right to receive one-tenth (1/10) of one Ordinary Share upon the consummation of a business combination, as described in the prospectus of the Company (File No: 333-282758), by providing the Company with written notice of the intention to convert at least two business days prior to the closing of the business combination. The number of Units to be received by the Payee in connection with such conversion shall be an amount determined by dividing (x) the sum of the outstanding principal amount payable to the Payee by (y) $10.00.

The issuance of the Note was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended.

A copy of the Note is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference. The foregoing description of the Note does not purport to be complete and is subject to, and is qualified in its entirety by, the full text of the Note.

 Item 3.02 Unregistered Sales of Equity Securities.

The information disclosed under Item 2.03 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02 to the extent required herein. The Units (and the underlying securities) issuable upon conversion of the Note, if any, (1) may not, subject to certain limited exceptions, be transferable or salable by the Payee until the completion of the Company’s initial business combination and (2) are entitled to registration rights.

Item 8.01. Other Events.

On February 12, 2026, the Company held an extraordinary general meeting, where the shareholders of the Company approved (i) the Business Combination Proposals (as defined in the definitive proxy statement filed by the Company (as amended and supplemented, the “Business Combination Proxy Statement”) with the U.S. Securities and Exchange Commission (the “SEC”) on January 13, 2026), (ii) the Amended M&A Proposal (as defined in the Business Combination Proxy Statement), and (iii) the Sole Director Appointment Proposal (as defined in the Business Combination Proxy Statement).

According to the information provided by the Company’s transfer agent, VStock Transfer, LLC (“VStock”), in connection with the votes to approve the Business Combination Proposals, as of February 23, 2026, 2,012,378 public shares of the Company were rendered for redemption (the “Business Combination Redemption”).

On February 13, 2026, the Company held another extraordinary general meeting, where the shareholders of the Company approved (i) the MAA Amendment Proposal (as defined in the definitive proxy statement filed by the Company (as amended and supplemented, the “Extension Proxy Statement”) with the SEC on February 3, 2026), and (ii) the Trust Amendment Proposal (as defined in the Extension Proxy Statement).

According to the information provided by VStock, in connection with the votes to approve the MAA Amendment Proposal and the Trust Amendment Proposal, as of February 23, 2026, 4,709,337 public shares of the Company were rendered for redemption (the “Extension Redemption”), which do not include the public shares rendered for the Business Combination Redemption.
