CVS vs PFE: How CVS Health and Pfizer Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: PFE is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CVS and PFE share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CVS and PFE exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

CVS Health runs three reporting segments. Health Care Benefits is the Aetna insurance business, which earns premiums from roughly 26 million medical members and profits when claims (the medical benefit ratio) stay below what it collects. Health Services is built around the Caremark pharmacy benefit manager, which negotiates drug prices and manages pharmacy claims for health plans and employers and generated over $48 billion of revenue in Q1 2026. Pharmacy and Consumer Wellness is the familiar retail footprint of CVS drugstores, which makes money filling prescriptions and selling front-of-store health and consumer goods, with same-store prescription volumes up nearly 7% in Q1 2026.

Pfizer is one of the world's largest pharmaceutical companies, developing, manufacturing, and selling prescription medicines and vaccines across many therapeutic areas. Its portfolio spans oncology (a strategic priority, expanded sharply by the acquisition of cancer drugmaker Seagen), vaccines (including pneumococcal franchise Prevnar and its COVID-19 vaccine Comirnaty, partnered with BioNTech), internal medicine and cardiology (such as the Vyndaqel/Vyndamax family and Eliquis, co-marketed with Bristol Myers Squibb), immunology and inflammation, and antivirals (including the COVID treatment Paxlovid). Pfizer makes money selling these drugs to wholesalers, pharmacies, hospitals, and governments worldwide. The company saw an enormous revenue surge from COVID-19 products during the pandemic, then a steep decline as that demand normalized, leaving it to refill growth through its pipeline, oncology expansion, and acquisitions while a wave of patent expirations looms later this decade. Founded in 1849 and headquartered in New York City, Pfizer is a mature, dividend-paying large-cap navigating a post-COVID reset.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• CVS drivers: Integrated model under one roof; Turnaround and improving Aetna margins.
• PFE drivers: Oncology expansion via Seagen; Broad, diversified portfolio.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The clearest risk is the medical-cost trend at Aetna: if claims reaccelerate, especially in Medicare Advantage, earnings can fall faster than premiums can be re-priced, which is what drove the 2023 to 2024 decline. For PFE, pfizer faces a significant patent cliff later this decade, with several major products losing exclusivity, pressuring revenue unless the pipeline and acquisitions fill the gap.

Pick CVS if you believe its drivers more; PFE if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CVS and PFE guides.

CVS. CVS trades at a low forward earnings multiple versus the broad market, which reflects lingering caution after the 2023 to 2024 Aetna downturn rather than current results. The value angle rests on whether improving margins and ~$400 billion of revenue can support the raised guidance. Figures are approximate and tied to the asOf date; verify live quotes and the latest filings before acting.

PFE. Pfizer trades at a below-market multiple and a high dividend yield, reflecting investor concern about the post-COVID revenue reset and a looming patent cliff. Its valuation balances substantial cash generation and diversification against questions over whether the pipeline and Seagen-led oncology push can restore durable growth.

Headline figures (approximate, 2026-06-27): CVS shows revenue (annual run-rate) ~$400 billion; FY2026 guidance at least ~$405 billion, adjusted eps (fy2026 guidance) ~$7.30 to $7.50 (Q1 2026 was ~$2.57), aetna medical benefit ratio (q1 2026) ~84.6%, improved from ~87.3% a year earlier, dividend yield ~2.5% (~$2.66 annual, ~$0.665 quarterly); PFE shows revenue (ttm) ~$60 billion, operating margin ~25%, recovering post-COVID normalization, net income (ttm) multi-billion, variable with COVID product swings, dividend yield ~6%, high for large-cap pharma.

CVS and PFE are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
