Fitch Ratings expects the planned separation of CVS Health Corporation into two independent publicly traded companies to be credit neutral for Aetna Life Insurance Company (ALIC), the group’s largest insurance subsidiary.
ALIC currently holds an Insurer Financial Strength (IFS) rating of ‘A’ with a Negative Outlook. Fitch does not anticipate that the transaction will materially increase leverage at CVS Health, which will remain Aetna’s parent company after the separation.
- Fitch Ratings expects CVS Health’s planned separation into two publicly traded companies to have no material impact on Aetna Life Insurance Company’s credit profile.
- Aetna Life Insurance retains its ‘A’ Insurer Financial Strength rating with a Negative Outlook, supported by improving operating performance in 2025 and 2026.
- The separation, expected in the first half of 2028, will divide CVS Health’s insurance and healthcare services operations from its retail pharmacy business.
However, the rating agency cautioned that a significant deterioration in the parent’s financial leverage, measured by debt-to-total capital or debt-to-EBITDA, could create downward pressure on ALIC’s financial strength rating.
Fitch Ratings also placed CVS Health Corporation’s and Aetna Inc.’s ‘BBB’ long-term issuer default ratings and associated debt ratings on Rating Watch Positive following CVS’s announcement that it intends to separate its retail pharmacy business into a new publicly traded company.
CVS Health to Separate Insurance and Pharmacy Operations by 2028
CVS Health announced its restructuring plans on November 4, 2026, outlining a separation into two companies with distinct business operations.
The healthcare solutions company, temporarily retaining the CVS Health name, will include:
- Aetna health insurance operations
- CVS Caremark pharmacy benefit management
- CVS Specialty
- Oak Street Health
- Signify Health
The second company, CVS Pharmacy, will operate approximately 9,000 retail pharmacies alongside mail pharmacy services, MinuteClinic, virtual care operations and the Health100 technology services business.
The separation is expected to be completed during the first half of 2028. Fitch expects the remaining CVS Health businesses to retain sufficient operational diversification despite the removal of retail pharmacy operations.
The rating agency considers the proposed business structure broadly comparable with those of major health insurance and pharmacy benefit management companies.
Aetna’s Financial Performance Improved in 2025 and 2026
Fitch highlighted a substantial recovery in operating performance across ALIC and its affiliated insurance subsidiaries during 2025 and 2026.
The improvement followed significant margin pressure in 2024, when several factors affected profitability. Medicare Advantage medical costs exceeded expectations, while pricing proved insufficient to offset higher healthcare utilization.
Lower Medicare Advantage Star ratings also negatively affected earnings, reducing the financial benefits associated with government quality assessments.
Meanwhile, Medicaid operations faced increased medical costs as eligibility redeterminations changed the composition of the insured population, leaving a higher proportion of members with more complex healthcare needs.
The subsequent operating recovery has improved Aetna’s credit fundamentals, although Fitch continues to monitor whether stronger margins can be sustained.
Fitch to Monitor CVS Health’s Debt and Capital Structure
Fitch does not currently expect the restructuring to breach ALIC’s existing rating sensitivities. Nevertheless, the final allocation of debt, capital and earnings between CVS Health and CVS Pharmacy will remain important considerations in future credit assessments.
The separation will reduce diversification at the parent-company level, but Fitch believes the remaining insurance, pharmacy benefit management and healthcare services operations will provide an adequate business mix.
The agency will reassess CVS Health’s credit profile as additional transaction details become available.
For Aetna, the principal credit risks remain the financial leverage of its parent company and the sustainability of improvements in insurance underwriting performance. Fitch’s assessment indicates that the planned separation alone is unlikely to change ALIC’s current financial strength rating.
