Going-concern doubt
— cleared May 12, 2026
The latest filing states the doubt was alleviated.
“The history of significant losses, the negative cash flow from operations, and the dependence by the Company on its ability to obtain additional financing to fund its operations in the past raised substantial doubt about the Company's ability to continue as a going concern.”View the 10-Q filed May 12, 2026

Institutional ownership from SEC Form 13F filings. Investment managers with more than $100 million in U.S. equities must disclose their positions every quarter, within 45 days of quarter-end, so the holdings shown can lag the market by up to a quarter.
The Jun 30, 2026 filing window is
still open — showing the latest known positions. Funds that have not filed yet
carry their prior-quarter positions; a fund that filed without this stock counts
as sold out.
