Grade
C63Well-capitalized pre-revenue advanced-nuclear (molten salt reactor) developer with no plant yet built but a strong balance sheet and policy tailwinds.
Strengths
- $297.8M cash with ~68 quarters of runway (95th pct) and current ratio 50.6 (99th pct)
- Selected for the DOE Advanced Reactor Pilot Program amid strong nuclear policy support
- Modest FCF burn (-$17.5M) relative to cash on hand
Risks
- No revenue, no constructed plant and no binding contracts — fully pre-commercial, binary technology risk
- Negative ROA (-9.2%) with going-concern language; long, uncertain licensing/deployment timeline
- Competition from other SMR/advanced-reactor technologies and nuclear public-perception risk
