Going-concern doubt
— flagged Aug 14, 2026
Substantial doubt about the company's ability to continue as a going concern.
“Based upon the Company’s current operating plan, it estimates that its $51.1 million of cash, cash equivalents and investments at June 30, 2026 may not be sufficient to fund its operating expenses and capital expenditure requirements through at least the next 12 months which raises substantial doubt as to our ability to continue as a going concern following the date of this Quarterly Report on Form 10-Q.”View the 10-Q filed Aug 14, 2026
