What the filings say Pressure ▼

Listing is at risk and the usual cures are constrained. Next thing to watch: a reverse-split proxy, a hearings-panel 8-K, or a Form 25.

Radar 80 (high attention) · dilution pressure elevated · listing risk high · governance risk low · runway 1.3 mo · strongest signal: Exchange deficiency notice (Sep 4, 2026)

What would confirm: Nasdaq 'Pending Suspension' listing, Form 25, hearings-panel denial 8-K, or a reverse-split proxy.
What would prove it wrong: 8-K announcing regained compliance; equity raise that restores stockholders' equity; MVLS back above threshold for 10+ days.

Direction is stated for existing shareholders (▼ more shares / survival or listing risk; ▲ insiders or holders buying). It is a characterization of the filings, not a forecast or a recommendation.

Listing cliff Pressure ▼ strength 0.80

Listing is at risk and the usual cures are constrained. Next thing to watch: a reverse-split proxy, a hearings-panel 8-K, or a Form 25. Exchange deficiency plus a structural reason cure is hard (sub-$5M float, negative equity, no cash, or a reverse split already used). Under Nasdaq's 2026 rules (one reverse split per 12 months; $5M MVLS floor with no cure period from Sept 2026) the usual escape hatches are narrower.

Would confirm: Nasdaq 'Pending Suspension' listing, Form 25, hearings-panel denial 8-K, or a reverse-split proxy.
Would invalidate: 8-K announcing regained compliance; equity raise that restores stockholders' equity; MVLS back above threshold for 10+ days.
