AZN vs BMY: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of November 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: BMY 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. AZN and BMY 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 AZN and BMY 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.

AstraZeneca is one of the world's largest biopharmaceutical companies, headquartered in Cambridge, England, with deep Anglo-Swedish roots. It develops and sells prescription medicines across four main areas: oncology (its biggest engine), cardiovascular-renal-metabolism, respiratory and immunology, and rare disease through Alexion, which it acquired in 2021. Flagship products include the cancer drugs Tagrisso, Imfinzi, Calquence, Lynparza (partnered with Merck) and Enhertu (partnered with Daiichi Sankyo), plus the diabetes and heart-failure drug Farxiga and rare-disease therapies like Ultomiris and Soliris. In 2025 the company reported total revenue of about $58.7 billion, up roughly 9%, and it has set a public ambition to grow that to $80 billion by 2030, with about half expected to come from the United States.

Bristol Myers Squibb is one of the largest global biopharmaceutical companies, developing and selling prescription medicines across oncology, hematology, immunology, cardiovascular, and neuroscience. It makes money primarily by selling patented branded drugs, with a portfolio that has historically leaned on blockbuster franchises such as the blood thinner Eliquis (co-marketed with Pfizer), the cancer immunotherapy Opdivo, and the multiple myeloma drug Revlimid. The company is working through a major patent cliff as several legacy products lose exclusivity, and it is rebuilding growth through a newer portfolio that includes drugs like Reblozyl, Opdualag, Camzyos, Sotyktu, and the schizophrenia treatment Cobenfy (acquired through Karuna). Bristol Myers grows both organically through its research pipeline and through large acquisitions (Celgene, MyoKardia, Karuna, Mirati). It is headquartered in New York and operates worldwide.

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

• AZN drivers: Oncology franchise and the $80 billion ambition; Deep late-stage pipeline.
• BMY drivers: New product portfolio ramp; Oncology and immunology depth.

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 dominant risk is the patent cliff: from around 2032, Tagrisso, Imfinzi and Calquence are expected to begin losing exclusivity, a headwind analysts have sized at more than $20 billion, so the whole thesis hinges on the pipeline replacing that revenue in time. For BMY, the central risk is the patent cliff: Eliquis, Opdivo, and other large products face loss of exclusivity, and generic or biosimilar competition can erode revenue quickly.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AZN if you believe its drivers more; BMY 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 AZN and BMY guides.

AZN. AstraZeneca trades at about 25 times trailing reported earnings but about 14.6 times forward earnings, a gap that reflects heavy amortisation and one-off charges in reported profit and consensus for 2026 core EPS near $10.05 rising to about $11.34 in 2027. After falling about 9.5% in 2026, the forward multiple sits near the low end of where a growth-oriented large-cap pharma usually trades, so the valuation now reflects more caution about the 2032 patent cliff than enthusiasm for the $80 billion 2030 goal. Q3 2026 results arrive October 30, with consensus revenue near $16.0 billion. Figures are approximate and tied to the asOf date; confirm live numbers before acting.

BMY. At about $60.80 on October 16, 2026, Bristol Myers trades near 9 times forward earnings, still low relative to large-cap pharma peers, which reflects market skepticism about replacing patent-cliff revenue even after a 40% one-year rally. The 4.2% dividend yield and strong cash flow are the bull-case anchors, while consensus for roughly flat 2027 EPS (about $6.62 versus $6.65 for 2026) captures the bear case. The 24 analysts in Yahoo's consensus carry a mean target near $66, and Q3 2026 results arrive on October 29.

Headline figures (approximate, October 2026): AZN shows revenue (ttm) About $61.4 billion; Q2 2026 revenue about $15.4 billion, up roughly 6% year over year, net income (ttm) About $10.5 billion, a net margin near 17%, with gross margin near 82%, eps Q2 2026 EPS $1.32 vs about $1.25 expected; trailing reported EPS about $6.69, p/e About 25x trailing reported earnings, about 14.6x forward; BMY shows revenue (ttm) ~$49.2 billion (Q2 2026 up ~5.7% YoY), q2 2026 adjusted eps $2.04 vs $1.60 consensus, operating margin ~34%, net income (ttm) ~$9.3 billion.

AZN and BMY 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. Walnut can show your combined AZN and BMY exposure against your real portfolio. It is not an investment adviser.
