AZN vs NVS: How AstraZeneca and Novartis AG Compare (2026)

Last updated August 2026

Short answer

AZN (AstraZeneca) and NVS (Novartis AG) share investment themes but are different businesses. The right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.

AZN vs NVS: the tie-breaker metrics

Same yardstick, side by side (as of August 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.

MetricAZNNVSWhat it tells you
Forward P/E14.6515.82Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up.
Trailing P/E25.4023.59Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price.
Beta0.220.50Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through.
Price vs 52-week range36% of range75% of rangeWhere today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why.
Price / book5.237.14How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price.

Before you buy: how AZN and NVS affect your concentration

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 NVS 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 NVS 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.

What does AstraZeneca (AZN) do?

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.

What does Novartis AG (NVS) do?

Novartis AG is a Swiss pharmaceutical company, and NVS is its US-listed American Depositary Receipt trading on the NYSE. Over the past several years it deliberately reshaped itself into a pure-play innovative-medicines business: it spun off the Alcon eye-care division in 2019 and separated the Sandoz generics and biosimilars unit in 2023, distributing those shares to Novartis holders. What remains is a focused portfolio of patented prescription drugs concentrated in four therapeutic areas: oncology, immunology, neuroscience, and cardiovascular-renal-metabolic disease. Oncology is its largest contributor, and the company has built a reputation for high core operating margins, reaching roughly 40% in 2025.

AZN vs NVS: how do they differ?

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.
  • NVS drivers: Priority growth brands offsetting the cliff; Focused, high-margin innovative-medicines model.

Which fits which kind of investor

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 NVS, the dominant risk is the patent cliff: Entresto, Tasigna, and Promacta/Revolade are losing exclusivity, and Entresto alone was the largest seller, so the priority growth brands must scale fast enough to fill the gap, which is not guaranteed.

AZN or NVS: which should you pick?

Pick AZN if you believe its drivers more; NVS 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 NVS guides.

AZN vs NVS: the full fundamentals

AZN. Figures are approximate and tied to the asOf date; confirm live numbers before acting. AstraZeneca trades as a growth-oriented large-cap pharma, so its valuation reflects confidence in the pipeline delivering on the $80 billion 2030 goal more than any single current metric. A patent cliff early next decade means today's revenue base is not guaranteed to persist, so how you weigh future launches matters more than trailing multiples.

NVS. Figures are approximate and qualitative, tied to the asOf date; verify live numbers before acting. The near-term picture is a revenue and profit dip as blockbusters lose exclusivity, so the stock is best judged on whether the newer growth brands and pipeline can restore mid-single-digit growth over the medium term rather than on a single trailing quarter.

Headline figures (approximate, Jul 2026): AZN shows revenue (ttm) Around $60 billion; 2025 total revenue was about $58.7 billion, up roughly 9%, with Q1 2026 up about 8% at constant currency, growth drivers Oncology (Tagrisso, Imfinzi, Calquence, Enhertu, Lynparza), rare disease (Ultomiris, Soliris) and metabolic launches; company ambition of $80 billion revenue by 2030, margins/profitability Solidly profitable large-cap pharma; heavy, sustained R&D spending funds the pipeline that the 2030 target depends on, dividend Pays a regular dividend; recent yield roughly 2%, modest for the sector but backed by large, growing cash flows; NVS shows revenue (ttm) Approximately $50 billion in annual net sales; Q1 2026 net sales were about $13.1 billion, down roughly 5% at constant currency on generic erosion, growth drivers Priority brands Kisqali, Kesimpta, Pluvicto, Leqvio, and Scemblix growing well above 50% at constant currency, offsetting Entresto's decline, margins/profitability High core operating margin, around 40% in 2025; 2026 guidance is for a low single-digit decline in core operating income on generic and R&D pressure, dividend Pays an annual dividend with a long record of increases; yield has recently been roughly 2%, subject to currency and Swiss withholding tax for ADR holders.

FAQ

What is the difference between AZN and NVS?

+

AstraZeneca is one of the world's largest biopharmaceutical companies, headquartered in Cambridge, England, with deep Anglo-Swedish roots. Novartis AG is a Swiss pharmaceutical company, and NVS is its US-listed American Depositary Receipt trading on the NYSE. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.

Is AZN or NVS the better stock?

+

Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.

Which is cheaper, AZN or NVS?

+

On forward P/E (as of August 2026), AZN trades at 14.65x and NVS at 15.82x, so AZN is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.

Should you own both AZN and NVS?

+

Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.

What are the risks of AZN vs NVS?

+

AZN: 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. Generic and biosimilar erosion is already visible, with first generics to Farxiga cleared in 2026. Pipeline risk is constant, since late-stage trial failures can erase billions in expected value quickly. China, about a tenth of revenue, carries added uncertainty after the company's former China head was indicted in a compliance case that drew investor lawsuits. Drug pricing policy, US tariffs and currency swings add further volatility, and as a large-cap pharma the stock can still fall sharply on a single disappointing readout or regulatory decision. NVS: The dominant risk is the patent cliff: Entresto, Tasigna, and Promacta/Revolade are losing exclusivity, and Entresto alone was the largest seller, so the priority growth brands must scale fast enough to fill the gap, which is not guaranteed. Pipeline risk is structural because late-stage trials can fail and regulators can reject or delay approvals, turning expected future revenue into a write-off. Large acquisitions such as Avidity add integration and financing risk and raised net debt. US drug-pricing policy, potential pharmaceutical tariffs, and pricing pressure are outside the company's control and could compress margins. Because NVS is a Swiss ADR, US investors also carry dollar-versus-Swiss-franc currency risk, and Swiss dividend withholding tax reduces net income for some holders. Concentration in a handful of growth drugs means a single clinical or commercial setback can move the stock.
