Material Changes vs. Prior Period
- Operating Costs: General and administrative costs increased significantly to $1,638,082 for Q3 2025 compared to $278,494 for Q3 2024, reflecting increased activity related to the business combination process.
- Interest Income: Interest earned on the Trust Account rose to $2,508,797 in Q3 2025 from $1,349,715 in Q3 2024, driven by higher interest rates and the full balance in the Trust Account.
- Liabilities: Current liabilities increased to $4,277,990 from $458,624 at year-end 2024, primarily due to accrued expenses and new related-party advances ($338,002) and a promissory note ($400,000).

Outlook, Risks, and Subsequent Events
Subsequent Event (Business Combination): On October 28, 2025, the Company completed its merger with Terrestrial Energy Inc. The combined entity renamed itself Terrestrial Energy Inc. and began trading under the ticker symbols "IMSR" and "IMSRW". The transaction generated gross proceeds exceeding $292 million, including a $50 million PIPE investment, with negligible redemptions.
Liquidity: As of September 30, 2025, the Company had a working capital deficit of $3,816,333 and cash of $350,389 outside the Trust Account. Management noted substantial doubt about the ability to continue as a going concern prior to the merger. The completion of the business combination has alleviated this doubt.
Risks and Controls:
- Internal Controls: Management concluded that internal controls over financial reporting were not effective as of September 30, 2025, citing a material weakness regarding an incorrect statement in a prior quarterly report footnote.
- Geopolitical Risks: The filing highlights risks related to the Russia-Ukraine and Israel-Hamas conflicts, which could impact global markets and the ability to complete a business combination.

- Deferred Underwriting Fees: Confirm the payment status of the $10,720,000 deferred underwriting fee payable upon the closing of the business combination.
