Going-concern doubt
— flagged May 14, 2026
Substantial doubt about the company's ability to continue as a going concern.
“Our losses from operations, negative operating cash flows and accumulated deficit, as well as the additional capital needed to fund operations within one year of the unaudited condensed consolidated interim financial statements issuance date, raise substantial doubt about our ability to continue as a going concern.”View the 10-Q filed May 14, 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.
