Going-concern doubt
— flagged May 13, 2026
Substantial doubt about the company's ability to continue as a going concern.
“our ability to continue as a going concern; - our need to raise substantial additional capital in the near future and our ability to raise such funds when needed and on acceptable terms; - if a financing is completed, it may not be a large enough financing to fully fund the company's operations”View the 10-Q filed May 13, 2026

Total shares sold short and not yet covered, reported to FINRA by broker-dealers twice a month. Each reading settles on the 15th and the last business day of the month and is published seven business days later — the next scheduled dates are listed at the top of the table. Days to cover divides the short position by average daily volume; a high value (above 5) can signal short-squeeze potential.
