Regulatory and Policy Changes Impact: Changes in government healthcare policies, Medicare Advantage funding, or ACA regulations could significantly impact Humana's revenue, profitability, and operational structure.

Rising Healthcare Costs and Claims Risk: Unforeseen increases in medical costs, higher-than-expected claims utilization, or new expensive treatments can erode profit margins and increase underwriting risk.

Intense Competition Threat: Humana operates in a highly competitive market, facing pressure from larger national insurers, regional players, and new entrants, which could lead to reduced market share or pricing pressure.
