Shelf registration — potential dilution
Actionable Insight ▼ Bearish

Monitor for a prospectus supplement that will disclose the specific terms of any offering. The high potential dilution (44% of market cap) suggests significant downside risk to the share price if executed, especially given recent insider selling and the company's negative cash flow.
