Going-concern doubt
— flagged Aug 14, 2026
Substantial doubt about the company's ability to continue as a going concern.
“The Company has incurred recurring losses from operations and does not yet have an established source of revenues sufficient to cover its operating costs. These conditions raise substantial doubt about the Company's ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Management evaluated conditions and events that raise substantial doubt and the Company's plans to mitigate those conditions over the one-year look-forward period from the date these consolidated financial statements are issued.”View the 10-Q filed Aug 14, 2026
