Going-concern doubt
— flagged May 13, 2026
Substantial doubt about the company's ability to continue as a going concern.
“These conditions raise substantial doubt about the Company’s ability to continue as a going concern. The Company’s recurring losses from operations, negative cash flows, and accumulated deficit raise substantial doubt about its ability to continue as a going concern. The completion of the private placement in April 2026 has improved the Company’s liquidity position; however, the Company’s ability to continue as a going concern is dependent upon its ability to generate sufficient revenue, manage operating expenses, and, if necessary, obtain additional financing”View the 10-Q filed May 13, 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.
