Actionable Insight ▼ Bearish

Monitor for actual sales under this equity line, which would provide cash but increase dilution. The stock's OTC listing and history of dilutive financings suggest continued pressure on share price. The ongoing litigation with Pooph Inc. and substantial doubt about going concern status add significant risk.
