• Business Combination: The Subscription Agreements are directly related to the Business Combination Agreement dated May 9, 2026, between Horizon Space Acquisition I Corp and SL Bio. This transaction is expected to create a new publicly traded entity following the merger.
• Price-Sensitive Information: The PIPE is a crucial capital-raising event that will provide additional funding to the combined company post-merger.

  • Ordinary shares (Trading Symbol: HSPT).
  • Rights, each whole right to acquire one-tenth of one ordinary share (Trading Symbol: HSPTR).

Potential Share Price Impact

The PIPE agreements and the business combination progress are material events that could significantly influence Horizon Space Acquisition I Corp’s share price. The successful completion of the business combination and PIPE financing will provide the combined entity with additional capital and a strengthened balance sheet, potentially increasing investor confidence and driving positive share price movement. Conversely, risks regarding completion, regulatory approvals, or failure to meet listing standards could negatively impact the share price.

The restriction on hedging activities and the grant of registration rights further support share price stability and liquidity for PIPE investors, which may be viewed positively by the market.

Important Shareholder Considerations

• Shareholders should closely monitor the progress of the business combination and PIPE financing, as delays or failures could have negative repercussions.
• The disclosure of risks and uncertainties in the filing, including possible total loss of investment and reliance on projections, underscores the need for careful due diligence.
• Shareholders will have access to definitive proxy statements and SEC filings, which should be reviewed thoroughly for further information and updates.
• The company’s status as an emerging growth company may affect its financial reporting and compliance, potentially impacting investor perception.
