Approach 1: Bayer Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow (DCF) model estimates what a company is worth by projecting its future cash flows and discounting them back to today’s value. This approach is particularly helpful for companies in established industries like pharmaceuticals, where future earnings can be projected with a reasonable degree of confidence.

Bayer’s latest reported Free Cash Flow (FCF) is €4.4 Billion. Analysts provide cash flow forecasts up to five years, and from 2029 onwards, Simply Wall St extrapolates further. The projections show Bayer’s FCF growing consistently, reaching €6.1 Billion by 2029. Over the next decade, annual cash flow is expected to gradually rise, with estimates extending beyond €7.4 Billion by 2035.

Based on these cash flows, the DCF model calculates Bayer’s intrinsic value at approximately €179.22 per share. Compared to the current share price, this valuation suggests the stock is trading with an 85.1% discount, indicating it is significantly undervalued according to this method.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Bayer is undervalued by 85.1%. Track this in your watchlist or portfolio, or discover 841 more undervalued stocks based on cash flows.

Approach 2: Bayer Price vs Sales

The Price-to-Sales (P/S) ratio is the preferred valuation metric for Bayer because it provides a clear view of how much investors are paying for each euro of the company’s revenue, regardless of current profitability. This approach is especially suitable for companies like Bayer, where factors such as legal settlements or restructuring can temporarily depress profits and make earnings-based multiples less reliable.

Growth prospects and perceived risk heavily shape what a “normal” or “fair” P/S ratio should be. A company with steady long-term growth and lower risks might command a higher multiple, while elevated risks or weaker growth trajectories justify a lower ratio.

Currently, Bayer trades at a P/S ratio of 0.57x. This is strikingly low compared to the Pharmaceuticals industry average of 2.78x and the peer group average of 1.96x, putting Bayer at a substantial discount. However, Simply Wall St’s proprietary “Fair Ratio” tool goes further by factoring in company-specific metrics such as Bayer’s growth outlook, profit margins, market cap, and risk profile. For Bayer, the Fair Ratio is calculated at 1.36x.

Unlike blunt comparisons to industry or peers, the Fair Ratio adjusts for Bayer’s unique situation and gives a more complete picture of what valuation is justified. Comparing Bayer’s actual 0.57x P/S ratio to its Fair Ratio of 1.36x shows the stock is meaningfully undervalued, even when you account for its specific risks and growth prospects.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Bayer Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let's introduce you to Narratives. A Narrative is Simply Wall St’s easy and dynamic tool that lets you apply your own story, your unique view of the company’s prospects, risks, and potential, directly to financial forecasts, resulting in a tailored fair value estimate. Narratives seamlessly connect a company’s background and future expectations with logical forecasts for revenue, profit margins, and fair value, creating a living bridge between numbers and real-world events.

Millions of investors on the Simply Wall St Community page use Narratives to compare their personal fair value to the current share price and decide whether to buy or sell. Narratives are kept up-to-date as new earnings, news, or industry changes emerge, so your viewpoint evolves alongside the business. For example, with Bayer, some investors may build a bullish Narrative around strong pharma launches and improved margins, setting fair value close to €39.0, while others with more cautious views on Bayer’s legal risks may see fair value as low as €23.0. No matter your position, Narratives make it simple to turn your perspective into action.
