Going-concern doubt
— flagged Aug 12, 2026
Substantial doubt about the company's ability to continue as a going concern.
“The Company's liquidity condition and mandatory liquidation within one year raises substantial doubt about the Company's ability to continue as a going concern for a period of time within one year after the date that the accompanying unaudited condensed financial statements are issued. Management plans to address this uncertainty through a Business Combination. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after the Combination Period. The Company intends to complete the initial Business Combination before the end of the Combination Period. However, there can be no assurance that the Company will be able to consummate any Business Combination by the end of the Combination Period.”View the 10-Q filed Aug 12, 2026
