Regulatory and Political Headwinds: Increased scrutiny on pharmacy benefit manager (PBM) practices, drug pricing, and potential changes in healthcare policy could negatively impact CVS's various business segments, particularly its pharmacy and Aetna operations.

Intense Competition: CVS faces significant competition across its retail pharmacy, PBM, and health insurance businesses from traditional rivals, online pharmacies like Amazon, and large retailers expanding into healthcare services.

Data Security and Privacy Risks: The company handles vast amounts of sensitive patient health and financial data, making it a prime target for cyberattacks. A significant breach could lead to severe financial penalties, lawsuits, and reputational harm.
