Fitch Ratings believes CVS Health’s planned separation will be credit neutral for Aetna Life Insurance Co., the credit rating agency reported Nov. 9.
One company, which will go by CVS Health in the interim, will encompass Aetna, pharmacy benefit manager CVS Caremark, CVS Specialty, primary care centers Oak Street Health and health evaluations business Signify Health. The other company, CVS Pharmacy, will include CVS’ 9,000 retail pharmacies, mail pharmacy, MinuteClinic and technology services business Health100.
Aetna Life’s current insurer financial strength rating is ‘A’/Negative. Fitch does not expect the split to significantly dampen Aetna Life’s company profile. Despite CVS Health losing some diversification, the parent’s remaining businesses are staying “sufficiently diversified and generally consistent with large health insurance and pharmacy benefit management peers.”
The agency does not currently anticipate that the transaction will breach Aetna Life’s rating sensitivities or materially increase CVS Health’s debt. Fitch added that a material deterioration in the parent company’s financial leverage could pressure the rating.
Aetna Life and its affiliated insurance companies had stronger operating performance in 2025 and 2026. Inadequate Medicare Advantage pricing amid higher medical utilization, lower MA star ratings and higher Medicaid acuity shaped margin pressure in 2024.
CVS’ announced split comes as insurers face vertical integration scrutiny from lawmakers, with tensions mounting during congressional hearings and through legislation.
