Approach 1: British American Tobacco Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what British American Tobacco might be worth today by projecting future cash flows and then discounting them back to a present value. It focuses on the cash that could be available to shareholders rather than accounting earnings.

For British American Tobacco, the latest twelve month free cash flow is reported at about £5.75b. Using a 2 Stage Free Cash Flow to Equity model, analyst inputs are used for several years, then Simply Wall St extrapolates further cash flows. In this model, projected free cash flow reaches about £8.43b by 2030, with intermediate annual projections between 2026 and 2035 discounted back to today.

Adding up these discounted cash flows leads to an estimated intrinsic value of £63.80 per share. Compared to the recent share price of £46.77, this DCF estimate suggests the stock is trading at a 26.7% discount on this measure.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests British American Tobacco is undervalued by 26.7%. Track this in your watchlist or portfolio, or discover 7 more high quality undervalued stocks.

Approach 2: British American Tobacco Price vs Earnings

For a profitable company like British American Tobacco, the P/E ratio is a useful shorthand for how much investors are paying for each pound of current earnings. It helps you compare what the market is willing to pay for this stock relative to others earning money today.

What counts as a "normal" P/E depends on what investors expect for future growth and how much risk they see in the business. Higher growth or lower perceived risk can justify a higher P/E, while lower growth or higher risk usually means a lower P/E is seen as more reasonable.

British American Tobacco currently trades on a P/E of 13.16x, compared with the Tobacco industry average of 12.22x and a peer group average of 17.01x. Simply Wall St also calculates a proprietary Fair Ratio for the stock, which in this case is 20.86x. The Fair Ratio represents the P/E that might be expected given factors such as earnings growth, industry, profit margins, market cap and specific risks.

This Fair Ratio is more tailored than a simple industry or peer comparison, because it attempts to adjust for British American Tobacco's own fundamentals rather than assuming all companies should trade on similar multiples. With the current P/E of 13.16x below the Fair Ratio of 20.86x, this approach points to the shares trading at a discount on earnings.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your British American Tobacco Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives take British American Tobacco from a collection of ratios and forecasts to a clear story that links your view of the business to a financial forecast and then to a fair value. All of this happens within Simply Wall St's Community page, where you can see how a more optimistic investor might back a higher fair value around £57.50, while a more cautious investor might align closer to £39.07. You can compare each fair value to the current price to decide whether the stock looks appealing or stretched, and have those Narratives automatically refreshed as new earnings or news arrive so your decision making stays grounded in both the story you believe and numbers that keep updating in real time.

For British American Tobacco, however, we will make it really easy for you with previews of two leading British American Tobacco Narratives:

Each one connects a clear story about the smokeless transition, regulation and cash generation to a specific fair value range, so you can decide which assumptions feel closer to your own view.

🐂 British American Tobacco Bull Case

Fair value in this narrative: £50.27 per share

Implied discount to this fair value at £46.77: about 7.0%

Analyst revenue growth assumption: 3.24% per year

• Assumes British American Tobacco steadily shifts its earnings mix toward reduced risk products, with Modern Oral, heated and vapour categories supporting margins as they gain scale.
• Focuses on digital transformation and cost efficiency programs that free up cash for reinvestment, dividends and buybacks, with debt reduction supporting financial flexibility.
• Treats regulation, illicit trade and ESG constraints as real headwinds, but expects the company to adapt sufficiently for earnings and dividends to remain resilient.

🐻 British American Tobacco Bear Case

Fair value in this narrative: £39.07 per share

Implied premium to this fair value at £46.77: about 19.7%

Analyst revenue growth assumption: 3.16% per year

• Starts from the view that tighter regulation, health concerns and ESG driven selling will weigh on British American Tobacco's rating and limit the benefit from new products.
• Assumes profit margins trend lower as combustible volumes soften, regulatory pressure stays intense and emerging market exposure adds currency and political risk.
• Accepts that smokeless categories and cost savings help support cash flow, but treats them as insufficient to fully offset long run pressure on the legacy cigarette business.

Taken together, these Narratives frame a reasonable range for British American Tobacco's fair value and highlight which levers, from smokeless growth to regulation, matter most for your own investment case.
