Outlook, Risks, and Contingencies

- Liquidity and Going Concern: The Company has a working capital deficit and minimal cash outside the Trust Account.

Additional capital may be required from the Sponsor or third parties.
- Redemption Rights: Public shareholders have the right to redeem their shares for a pro-rata portion of the Trust Account upon the completion of a Business Combination or liquidation.
- Risk Factors: Risks include failure to complete the Business Combination, geopolitical instability affecting markets, and the inability to secure additional financing.
Investor Verification Checklist
- Transaction Status: Verify the current status of the Parataxis merger and whether the amended underwriting fee of $6.03 million is accurate and binding.
- Liquidity Runway: Confirm the Company's ability to fund operations until the August 19, 2026 deadline given the $2,372 cash balance and $342,040 working capital deficit.
- Related Party Obligations: Review the terms of the $390,000 advance from the Sponsor and the potential for further Working Capital Loans.
- Redemption Value: Note the redemption value per share is approximately $10.76 as of March 31, 2026.
- Deferred Fees: Understand that $10.3 million in deferred underwriting fees and $2.68 million in deferred legal fees are contingent on the successful closing of the Business Combination.
