Going-concern doubt
— flagged May 14, 2026
Substantial doubt about the company's ability to continue as a going concern.
“the expectation of significant future costs raises substantial doubt about the Company's ability to continue as a going concern within one year after the date that the financial statements are issued. Management plans to address this uncertainty through debt or equity financing. There is no assurance that the Company's plans to raise capital or to consummate a business combination will be successful within the Completion Window.”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.
