AstraZeneca (LSE:AZN) Stock Still Looks Like A Bargain Today

Simply Wall St·09/10/2026 00:33:04
Listen to the news

AstraZeneca has delivered a 59.1% gain over the past 5 years, yet the broader valuation checks still flag the stock as pricing in less optimism than many peers. With a recent pullback leaving the share price lower year to date, investors are weighing a softer near term run against signals that the market may be underpaying for the long term pipeline.

  • The 59.1% return over 5 years points to solid long haul wealth creation, even though shorter term performance has been far more muted.
  • Progress across oncology and respiratory drugs, including recent approvals and late stage trial wins, can support expectations for future cash flows, while execution risk around clinical outcomes and regulatory decisions may still cap how much investors are willing to pay today.
  • AstraZeneca screens as undervalued on the broader checks, with a value score of 5. This suggests the current price leans cheap rather than fully pricing in the portfolio story.

The stock's next move may depend on whether the market keeps treating AstraZeneca as a cautious pipeline bet or starts to value it more in line with the long run returns it has already delivered.

Is AstraZeneca Still Cheap on Earnings?

The P/E ratio is useful here because AstraZeneca already reports earnings that investors can compare directly with the price you pay for each share.

Through this lens, AstraZeneca trades on a P/E of 23.4x, which is very close to the wider pharmaceuticals sector average of 22.5x. Against that broad yardstick, the stock looks roughly in line with the typical large drug maker. The peer group used in the model is richer at 44.4x, which indicates that investors in comparable businesses are currently paying a higher earnings multiple.

The more tailored fair P/E for AstraZeneca, which incorporates factors such as its risk profile, profitability and market size, is 43.4x. This is above the current 23.4x earnings multiple, so the shares appear to trade at a discount on this framework. Despite recent positive trial and approval news across oncology and respiratory treatments, the valuation is below both the peer average and the modelled fair level.

On a P/E basis, AstraZeneca appears undervalued, with the current earnings multiple below the level suggested by the fair ratio and by peers.

The Bottom Line

AstraZeneca screens as undervalued on earnings, with the current P/E sitting well below the tailored fair multiple and the richer peer group used in the model. The valuation gap really comes down to whether the oncology and respiratory portfolio can keep justifying a higher earnings multiple as existing drugs mature and patent expiries get closer. If you think execution on late stage projects offsets that patent risk, the current discount may reflect the market being overly cautious. If those trials stumble or competition becomes more intense, the lower P/E may simply be the price the market assigns to that uncertainty.
