The news: CVS Health reported $2.96 billion in Q1 net income, up about 66% year over year. Quarterly revenues reached $100.4 billion, a 6% YoY increase, and the company raised its full-year revenue outlook to $405 billion.

Driving the news: Aetna’s ongoing turnaround drove CVS’ Q1 earnings success and improved guidance.

Aetna, the third-largest US insurer, is rebounding as it stabilizes high medical costs and more effectively manages patient utilization.

• Aetna’s adjusted operating income rose 53% YoY, eclipsing $3 billion in Q1.
• Its medical benefit ratio, which measures the share of premiums spent on medical care, dropped to 84.6% from 87.3% in the prior year. Lower ratios signal higher health plan profits and are a key metric investors scrutinize each quarter.

Why it matters: For large health insurers, enrollment growth has long been a key earnings driver. This dynamic was particularly strong in Medicare Advantage, where private plans like Aetna could generate per-member profit by effectively managing care costs.

However, profitability today increasingly depends on margin discipline rather than membership growth. CVS and UnitedHealth Group have focused on exiting insurance markets where high-cost members (i.e., older and sicker) have pressured profitability. CVS, for example, exited the ACA marketplace entirely, impacting about 1 million members across 17 states, and also cut hundreds of thousands of Medicare Advantage enrollees to restore margins.

Implications for healthcare companies and consumers: US healthcare giants must tighten cost controls in their core insurance segments to regain Wall Street’s confidence. CVS has delivered on this over the past few quarters, with shares up about 30% YoY and 7% on Wednesday after its Q1 earnings. UnitedHealth, meanwhile, is beginning to reassure investors after a bruising 2025.

While insurance companies refine their parameters, consumers will scramble for new plans, less generous coverage, and worse benefits. CVS CFO Brian Newman told Bloomberg on Wednesday that cutting patient benefits to meet financial targets is on the table, while major Medicare Advantage player Humana said in last week’s earnings that it plans to reduce supplemental benefits in 2027.
