Going-concern doubt — flagged Aug 14, 2026

Substantial doubt about the company's ability to continue as a going concern.

“Based on the Company’s current liquidity position, projected operating costs, and the requirement to complete a Business Combination by August 4, 2027 or otherwise liquidate, the Company may not have sufficient liquidity to meet its obligations for at least twelve months from the issuance date of these unaudited condensed financial statements. Accordingly, there is substantial doubt about the Company’s ability to continue as a going concern.”
