Approach 1: LyondellBasell Industries Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a company might be worth by projecting its future cash flows and discounting them back to what they could be worth to investors today.

For LyondellBasell Industries, this model uses a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month free cash flow is about $628.7 million. Analysts provide detailed forecasts for several years, and Simply Wall St then extrapolates further out. By 2035, these extended projections reach around $3.2 billion in free cash flow, with each year between now and then converted into today’s dollars using a discount rate.

Adding these discounted cash flows together gives an estimated intrinsic value of about $114.46 per share. When compared with the recent share price of $72.30, the model output indicates that the stock is trading at a 36.8% discount to this estimate based on this DCF view alone.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests LyondellBasell Industries is undervalued by 36.8%. Track this in your watchlist or portfolio, or discover 48 more high quality undervalued stocks.

Approach 2: LyondellBasell Industries Price vs Sales

For profitable companies, revenue based measures such as the price to sales, or P/S, ratio can be a useful sense check because they tie the share price back to the top line that ultimately supports earnings and cash flows. Investors usually expect higher P/S ratios when they see stronger growth potential or lower perceived risk, and lower P/S ratios when growth expectations are more muted or risks feel higher.

LyondellBasell Industries currently trades on a P/S ratio of about 0.77x. This sits below both the Chemicals industry average of around 1.07x and a peer average of about 0.84x. On the face of it, that points to a lower sales based valuation than many similar businesses.

Simply Wall St’s Fair Ratio for LyondellBasell, at roughly 1.07x, is a proprietary estimate of what the P/S could be given factors such as its earnings profile, industry, profit margins, market value and risk characteristics. This approach can be more tailored than a simple comparison with peers or the sector because it adjusts for company specific traits instead of assuming all firms deserve the same multiple. With the current 0.77x P/S sitting below the 1.07x Fair Ratio, the shares screen as undervalued on this metric.

Result: UNDERVALUED

For LyondellBasell Industries, however, we will make it really easy for you with previews of two leading LyondellBasell Industries Narratives:

🐂 LyondellBasell Industries Bull Case

Fair value: US$86.92

Current price vs this fair value: about 16.8% below the narrative fair value

Assumed revenue trend: 5.07% annual decline over the next 3 years

  • Backers of this view focus on cost cuts, portfolio simplification and advanced recycling projects that they expect to support stronger margins and higher free cash flow over time.
  • They work with analyst assumptions that margins could rise from 0.4% to 10.5% by 2028, with earnings at US$3.5b and a future P/E of 10.1x, which they see as consistent with the US$86.92 fair value.
  • Supporters of this narrative point to long term demand for polymers, feedstock cost advantages outside Europe and the potential for buybacks and dividends, while still flagging risks around Europe, energy markets, circular plastics and global oversupply.

🐻 LyondellBasell Industries Bear Case

Fair value: US$38.00

Current price vs this fair value: about 90.3% above the narrative fair value

Assumed revenue trend: 3.16% annual decline over the next 3 years

  • This view leans on concerns that tighter rules on plastics, higher carbon and compliance costs and growth in alternative materials could pressure demand and pricing for LyondellBasell's legacy products.
  • The narrative works with assumptions of revenues at US$25.7b and earnings of US$1.6b by 2028, with an 11.1x P/E and an 8.8% discount rate, which together support a US$38.00 fair value.
  • Even though it acknowledges cost advantages, recycling projects and portfolio actions, it treats oversupply, capital intensity and the risk of weaker long term cash generation as reasons to be cautious about paying well above this fair value.

Both of these Narratives take the same company data and reach very different conclusions, which is exactly the point. Your task is to decide which story feels closer to how you see LyondellBasell Industries and whether the current US$72.30 share price lines up with your version of fair value.
