Going-concern doubt
— flagged Aug 3, 2026
Substantial doubt about the company's ability to continue as a going concern.
“Based on our expectation of continued operating losses for at least the near term and our current operating plan, we anticipate our existing cash and cash equivalents, together with net proceeds from the 2026 Private Placement and IPO, will not be sufficient to fund our operations for the next twelve months, absent additional financing or material changes to our operating plan. Accordingly, we determined that there is substantial doubt about our ability to continue as a going concern for the twelve-month period following the issuance of these financial statements.”View the 10-Q filed Aug 3, 2026
