7. Key Risks & Mitigants
| Severity | Risk Factor | Mitigant |
|---|---|---|
| High | Negative operating margin | RCM uplift bridge shows clear path to profitability; working capital release provides near-term cash cushion |
| Medium | Elevated Medicaid exposure (24.4%) | Medicaid reimburses below cost in most states. Mitigant: denial reduction lever has highest impact on Medicaid claims |
| High | Elevated distress probability | Model estimates 54.6% probability of financial distress. Mitigant: distressed entry pricing (7-9x) compensates for risk |
