Going-concern doubt
— flagged May 18, 2026
Substantial doubt about the company's ability to continue as a going concern.
“These conditions raise substantial doubt regarding the Company’s ability to continue as a going concern for a period of one year from the date these unaudited condensed financial statements are issued. Management’s plan to mitigate the conditions that raise substantial doubt includes generating additional revenues, deferring certain projects and capital expenditures and eliminating certain future operating expenses for the Company to continue as a going concern. However, there can be no assurance that the Company will be successful in completing any of these options. As a result, management’s plans cannot be considered probable and thus do not alleviate substantial doubt about the Company’s ability to continue as a going concern.”View the 10-Q filed May 18, 2026
