Going-concern doubt
— flagged Aug 19, 2026
Substantial doubt about the company's ability to continue as a going concern.
“The Company does not have sufficient resources to fund its operations past twelve months from the date these consolidated financial statements are available to be issued. The Company expects that additional capital may be required during the next 12 months to continue executing its business plan and to meet its obligations as they become due. Accordingly, these conditions raise substantial doubt about the Company's ability to continue as a going concern within one year after the date these financial statements are issued.”View the 10-Q filed Aug 19, 2026
