Diageo (LSE:DGE) Stock Looks Cheap Despite A 51% Three Year Slide

Simply Wall St · 1d ago

Diageo’s share price has had a tough run over the last few years, yet its current valuation checks suggest the stock now screens as relatively cheap on several measures, creating a clear tension between weak past returns and a more supportive valuation profile.

  • Over the past 3 years, Diageo’s share price has declined about 50.5%, which puts recent returns and sentiment firmly on the back foot.
  • For a global branded spirits group like Diageo, long term brand strength and cash generation can support valuation, while any sustained pressure on volumes, pricing, or input costs may weigh on what investors are willing to pay.
  • Across Simply Wall St’s broader checks, Diageo screens as undervalued in 6 of 6 valuation tests, which leans toward the stock being priced below what those fundamentals imply.

The issue now is whether Diageo’s current share price already reflects the weak past share performance or if the valuation signals indicate room for a more favorable outcome ahead.

Find out why Diageo's -18.2% return over the last year is lagging behind its peers.

Is Diageo Still Cheap on Earnings?

The P/E ratio suits Diageo because earnings are a key way investors weigh the value of established consumer brands against what they are paying for each share.

Right now, Diageo trades on a P/E of about 18.9x, which sits slightly above the Beverage industry average of roughly 17.4x but far below the peer group average of about 43.3x. Simply Wall St’s fair P/E ratio for Diageo is 22.9x, reflecting what the multiple might be given its business profile, margins and risk level. Against that yardstick, the current P/E is several turns lower, indicating that investors are not paying as much for each pound of earnings as this framework would imply.

For you as a shareholder or prospective buyer, this gap between the current 18.9x and the fair ratio of 22.9x highlights a stock that appears on the cheaper side relative to the earnings multiple suggested by these fundamentals.

On the P/E multiple alone, Diageo stock currently appears undervalued relative to the earnings-based fair ratio.

The Bottom Line

Diageo now looks undervalued on the market multiple workhorse, with the current P/E sitting below the earnings multiple suggested by the broader checks. That leaves the stock’s appeal resting less on uncovering a hidden growth story and more on whether the market is over penalising the risks around volumes, pricing and margins. From here, the key question is whether Diageo can deliver steady enough earnings and margin resilience for that discount to close, or whether the current valuation simply reflects a business facing ongoing pressure that investors are not yet willing to look through.
