Going-concern doubt
— flagged Jun 1, 2026
Substantial doubt about the company's ability to continue as a going concern.
“These conditions raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements included in this Annual Report are issued. The Company’s ability to continue as a going concern is dependent upon its ability to generate sufficient cash flows from operations, obtain additional financing, and/or execute strategic transactions. Management is actively evaluating various alternatives to improve liquidity and support ongoing operations, including, but not limited to, raising additional capital through equity or debt financings, pursuing strategic partnerships, and reducing operating expenses. However, there can be no assurance that such plans will be successfully implemented or that sufficient funding will be available on terms acceptable to the Company, if at all.”View the 10-K filed Jun 1, 2026
