Going-concern doubt
— flagged May 13, 2026
Substantial doubt about the company's ability to continue as a going concern.
“These cash and restricted cash balances considered with our historical and expected future cash used in operations, notwithstanding our Strategic Workforce and Cost Reduction Plan and the impact of the Amended Loan and Security Agreement, raises substantial doubt about the Company's ability to continue as a going concern within twelve months after the date that the accompanying condensed consolidated financial statements are issued.”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.
