Is CVS Stock Worth Buying as Aetna Recovers but PBM Risks Persist?

Read MoreHide Full Article

Key Takeaways

  • CVS' Health Care Benefits operating income rose to $912 million as Aetna's medical benefit ratio improved.
  • CVS Pharmacy operating income rose 10.6%, supported by core pharmacy strength and Rite Aid assets.
  • CVS generated $15.32 billion in operating cash flow, reduced debt and plans to resume share buybacks.

CVS Health (CVS - Free Report) is entering a more constructive earnings phase as Aetna margins recover, pharmacy execution improves and cash generation strengthens. Those gains give investors a clearer recovery case after a difficult stretch.

The offset is persistent pressure in pharmacy benefit management, medical membership and reimbursement. CVS looks inexpensive against peers, but the investment case still depends on execution through 2027.

CVS Valuation Leaves Room for a Recovery Case

CVS trades at 10.40X forward 12-month earnings, below 16.33X for the Zacks sub-industry and 18.65X for the S&P 500. That discount leaves room for upside if earnings recovery remains on track.

The stock is not unusually cheap versus its own history. Its five-year median is 10.27X, with a range of 6.44X to 13.87X, suggesting current valuation is close to a normal CVS multiple.

Aetna Recovery Strengthens CVS Earnings Momentum

Health Care Benefits adjusted operating income reached $912 million in the third quarter of 2026, up from $314 million a year earlier. The medical benefit ratio improved to 91.3% from 92.8%, driven mainly by better Government business performance.

Management raised the segment's 2026 adjusted operating income outlook to at least $5.4 billion. It also expects further margin improvement in 2027, supported by Medicare Advantage pricing actions and disciplined underwriting.

CVS Pharmacy Execution Adds a Second Profit Driver

Pharmacy & Consumer Wellness adjusted operating income increased 10.6% year over year to $1.64 billion even as revenues declined 2% to $35.50 billion. Core pharmacy strength and Rite Aid asset contributions supported the improvement.

Prescription volume also moved higher, while pharmacy economics improved. Those gains are helping counter regulatory-related drug-price reductions, generic introductions and continued reimbursement pressure, which remain constraints on revenue growth.

PBM Reform Keeps CVS Risk Elevated Into 2027

Health Services remains the main source of uncertainty. CVS expects 2027 adjusted operating income of at least $7 billion, below its 2026 outlook of at least $7.25 billion, reflecting 340B weakness, a less favorable selling season and health plan client membership attrition.

The Cigna Group (CI - Free Report) operates Evernorth Health Services, which includes pharmacy benefits, home delivery and specialty pharmacy capabilities. UnitedHealth Group (UNH - Free Report) said Optum Rx is moving to a transparent, fee-based pharmacy care model offered to all PBM customers. For CVS, specialty strength and Health Care Delivery improvement must help offset the Caremark reset.

CVS Cash Flow Supports Debt Reduction and Buybacks

Operating cash flow reached $15.32 billion in the first nine months of 2026, while long-term debt fell to $57.22 billion from $60.50 billion at 2025-end. CVS repaid $4.06 billion of long-term debt during the period.

The company also paid $2.58 billion in dividends and achieved its leverage goal ahead of schedule. Management plans to resume share repurchases in the fourth quarter, giving CVS more flexibility as earnings recover.

CVS Signals Still Favor Selective Optimism

CVS offers a credible recovery setup, but the case is not one-sided. Aetna's improving margins, pharmacy profit growth and stronger cash generation support a constructive view, while PBM pressure, reimbursement headwinds and membership declines keep execution risk elevated.

The stock currently carries a Zacks Rank #2 (Buy), along with a VGM Score of A, Value Score of A, Growth Score of A and Momentum Score of B. That combination points to favorable near-term characteristics across value, growth and momentum, while the operating risks argue for selective rather than unconditional optimism.
