Welcome to our dedicated page for Horizon Space Acquisition II SEC filings (Ticker: HSPT), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
The SEC filings for Horizon Space Acquisition II Corp. (HSPT) provide detailed insight into its activities as a Cayman Islands exempted special purpose acquisition company (SPAC) listed on Nasdaq. Through current reports on Form 8-K, annual reports on Form 10-K, and other submissions, the company discloses material agreements, financing arrangements, and progress toward completing its initial business combination.
For HSPT, key filings include Form 8-K reports describing unsecured promissory notes issued to its sponsor or sponsor designees. These notes bear no interest, are repayable upon the earlier of the consummation of a business combination or the expiry of the company’s term, and may be convertible into private units at a price referenced to $10.00 per unit. The filings explain the composition of these private units, which can include ordinary shares, rights to receive fractions of ordinary shares, and, in some cases, warrants.
Another important aspect of Horizon Space Acquisition II Corp.’s filings is the disclosure of its ability to extend the deadline to complete its initial business combination. The company’s charter allows for extensions when specified extension fees are deposited into the trust account for public shareholders. Form 8-K filings describe these extension payments and the related promissory notes, outlining how the SPAC manages its timeline to pursue a suitable transaction.
Filings also cover the definitive Business Combination Agreement with SL Bio Ltd. and the creation of SL Science Holding Limited (PubCo) as the proposed listed entity. Investors can review registration statements and proxy materials referenced in public announcements to understand the structure of the proposed mergers, the exchange of securities into PubCo ordinary shares, and the conditions required for closing.

Horizon Space Acquisition II Corp. is clarifying how public shareholders can redeem their shares around two key shareholder meetings tied to its proposed business combination with SL BIO Ltd. and a potential deadline extension.
The company explains that investors who already elected redemption for the February 12, 2026 Business Combination Meeting and want their shares redeemed whether the merger closes or the extension is approved must also instruct the transfer agent to redeem in connection with the Extension Proposals by 5:00 p.m. Eastern Time on February 11, 2026. If the Extension Meeting on February 13, 2026 is not held or the Extension Proposals are not implemented, those shares will instead be redeemed if the business combination is consummated, unless the shareholder withdraws the request.
The filing confirms there is no change to the Business Combination Meeting’s time, location, record date, or proposals, and reminds shareholders of the February 10, 2026 redemption deadline for that meeting and that record-date holders can vote even if they later sell their shares.
Horizon Space Acquisition II Corp. filed an update explaining how public shareholders can redeem their shares around its proposed business combination with SL BIO Ltd. and a related deadline extension vote.

The filing confirms there is no change to the date, time, location, or record date for the February 12, 2026 business combination meeting, and repeats the February 10, 2026 and February 11, 2026 redemption deadlines.

Horizon notes that if the Extension Meeting is not held and the extension is not implemented, shares submitted for redemption for both meetings will be redeemed upon consummation of the Business Combination unless the request is withdrawn, while shares redeemed only for the Extension Meeting would not be redeemed in that scenario.

Horizon Space Acquisition II Corp. is asking shareholders to approve amendments to its charter and trust agreement at a February 13, 2026 extraordinary meeting. These changes would let the SPAC extend its deadline to complete an initial business combination, including the proposed SL Bio merger, from February 18, 2026 up to February 18, 2027 through up to twelve one‑month extensions.
For each monthly extension, the sponsor or its designee would deposit the lesser of $50,000 or $0.033 per remaining public share into the trust account. Public shareholders may redeem some or all public shares in connection with the extension vote for cash equal to their pro rata portion of the trust, which was about $10.53 per share as of December 29, 2025, compared with a Nasdaq closing price of $10.55 that day. If the extension is not approved and no deal closes by the current deadline (or existing extensions), the company may redeem all public shares and liquidate, and the rights in the units would expire worthless.
