Horizon Space Acquisition II Corp. 8-K

What Happened

• Horizon Space Acquisition II Corp. (HSPT) filed an 8-K on Feb 3, 2026 and issued a press release clarifying how public shareholders can redeem shares in connection with its proposed business combination with SL BIO Ltd. and a separate vote to extend HSPT’s time to complete a business combination (the “Extension Proposals”).
• HSPT previously filed the Definitive Proxy Statement for the Business Combination on Jan 13, 2026; the Extension Proxy Statement was filed and mailed on Feb 3, 2026. The Extension Meeting is scheduled for Feb 13, 2026; the Business Combination Meeting remains set for Feb 12, 2026 at 9:00 a.m. ET.

Key Details

• If you previously elected to redeem your public shares for the Business Combination Meeting and want redemption to occur whether the Business Combination closes or the Extension Proposals are implemented, you (or your broker/nominee) must instruct HSPT’s transfer agent to redeem the shares in connection with the Extension Proposals by 5:00 p.m. ET on Feb 11, 2026 (Extension Meeting redemption deadline).
• If HSPT does NOT hold the Extension Meeting and does NOT implement the Extension Proposals, any shares originally submitted for redemption in connection with the Business Combination Meeting that were also instructed to be redeemed in connection with the Extension Meeting will instead be automatically subject to redemption in connection with the consummation of the Business Combination—unless you withdraw the redemption.
• If you only elect to redeem in connection with the Extension Meeting (and did not earlier submit redemption for the Business Combination Meeting), those shares will NOT be redeemed if the Extension Meeting is not held and the Extension Proposals are not implemented.
• Business Combination Meeting details unchanged: meeting time 9:00 a.m. ET on Feb 12, 2026; Business Combination redemption deadline remains 5:00 p.m. ET on Feb 10, 2026; record date for voting was close of business Dec 29, 2025. Transfer agent contact: VStock Transfer (action@vstocktransfer.com). Proxy solicitor: Advantage Proxy (877-870-8565; ksmith@advantageproxy.com).

Why It Matters

• The notice clarifies exactly how and by when shareholders must act to ensure redemptions occur under both the pending Business Combination with SL Bio and the potential extension vote. Missing the stated deadlines or only choosing the extension election (without the earlier Business Combination redemption) could mean your shares are not redeemed as you expect.
• Redemption outcomes affect how much cash remains in HSPT’s trust at closing, which can influence the combined company’s cash position and the economics of the deal. Investors should read the Definitive Proxy Statement, Extension Proxy Statement and related SEC filings before voting or submitting redemption instructions.
