Going-concern doubt
— flagged Aug 14, 2026
Substantial doubt about the company's ability to continue as a going concern.
“The Company lacks the financial resources it needs to sustain operations for a reasonable period of time, which is considered to be one year from the date of the issuance of the financial statements. Therefore, management has determined that these conditions raise substantial doubt about the Company's ability to continue as a going concern until the earlier of the consummation of the Business Combination or the date the Company is required to liquidate.”View the 10-Q filed Aug 14, 2026
