Diageo (LSE:DGE) Stock May Be 49% Undervalued As Cameronbridge Strike Looms

Simply Wall St·09/22/2026 09:30:52
Listen to the news

Diageo has seen its share price weaken over several years, so the immediate question for you is whether the current valuation still lines up with the cash the business is expected to generate. With the stock under pressure and sentiment shaped by both market returns and company news, the spotlight is firmly on its cash flows.

  • The share price has fallen 47.7% over the past 5 years, which puts the focus on whether that decline already reflects the cash the group may produce in the future.
  • The planned strike at the Cameronbridge distillery and the broader job cuts program may reshape Diageo’s cost base and production profile, which can affect margins, cash generation and the timing of those cash flows.
  • What if you looked at Diageo through its earnings instead? See why Diageo's 27.6x P/E tells a different valuation story.

The stock's next move may depend on whether today's price is justified by the intrinsic value suggested by its cash flows.

Does Diageo Look Undervalued on Cash Flow?

The Discounted Cash Flow (DCF) approach here focuses on the cash Diageo can return to shareholders over time. On this model, the business is generating trailing twelve month free cash flow of about US$2.98b, with the projections assuming growing free cash flows rather than a shrinking base. That growth is expected to moderate over time, which fits a mature consumer goods group rather than a high risk early stage story.

Those cash flow assumptions point to an estimated intrinsic value that sits substantially above the current share price of £16.14. The planned strike and job cuts at the Cameronbridge distillery help explain why the market might still be pricing Diageo below what its projected cash generation suggests. That gap between price and DCF output is what you are really weighing. Find out what Diageo could be worth using our Discounted Cash Flow (DCF) estimate.
