Substantial doubt about the company's ability to continue as a going concern.
“Management believes that, given the Company’s current cash position and forecasted negative cash flows from operating activities over the next twelve months, there is substantial doubt about its ability to continue as a going concern after the date that is one year from the date that these financial statements are issued without the closing of the Merger.”View the 10-Q filed May 15, 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.
Peer-relative percentile rank across all stocks reporting short interest at the latest settlement date (2026-07-15). Weighted mean of the available factors (short interest 30%, days to cover 20%, price vs VWAP 15%, short-volume trend 15%, short-interest change 10%, fails-to-deliver 10%) plus catalyst boosts (price spike, volume surge, earnings within days), capped at +20 and clamped to 100.
