- Recent news coverage has largely focused on the broader chemicals sector, regulatory developments, and shifting expectations around demand cycles. All of these factors influence how investors view Westlake's prospects. These themes help explain why the share price has seen both strong year to date gains and periods of weakness.

Approach 1: Westlake Discounted Cash Flow (DCF) Analysis
A Discounted Cash Flow, or DCF, model estimates what a stock could be worth today by taking projected future cash flows and discounting them back into present dollars.
For Westlake, the latest twelve month free cash flow is a loss of about $482.1 million, so the model relies heavily on future projections. Analyst estimates and extrapolations point to free cash flow of $635.1 million by 2028, with a series of annual projections across the next decade ranging from about $424.1 million in 2026 to $504.5 million in 2035. Simply Wall St uses a 2 Stage Free Cash Flow to Equity approach, where near term analyst forecasts are combined with longer term extrapolated cash flows, all in $.
When these projected cash flows are discounted back, the model produces an estimated intrinsic value of about $68.99 per share. Compared with the current share price of about $87.27, this implies Westlake is around 26.5% overvalued based on this DCF approach alone.
Result: OVERVALUED
Our Discounted Cash Flow (DCF) analysis suggests Westlake may be overvalued by 26.5%. Discover 47 high quality undervalued stocks or create your own screener to find better value opportunities.
Approach 2: Westlake Price vs Sales
For companies where earnings can be volatile, the P/S ratio is often a useful cross check because it focuses on revenue rather than profit, which can swing with margins and one off items.
In general, higher expected growth and lower perceived risk can justify a higher “normal” or “fair” P/S multiple, while slower growth or higher risk tend to support a lower multiple. So it helps to compare Westlake’s P/S both with its sector and with what its fundamentals might warrant.
Westlake currently trades on a P/S of about 1.02x. That is above the peer average of 0.74x, and just below the wider Chemicals industry average of 1.13x. Simply Wall St’s Fair Ratio for Westlake is 0.99x, which is its estimate of an appropriate P/S given factors such as earnings growth profile, profit margins, industry, market cap and specific risks.
This Fair Ratio can be more useful than a simple peer or industry comparison because it adjusts for company specific characteristics rather than assuming every stock should trade at the same level. With the current P/S of 1.02x sitting very close to the Fair Ratio of 0.99x, Westlake’s valuation on this measure appears to be roughly in line with that estimate.

Upgrade Your Decision Making: Choose your Westlake Narrative
Earlier it was mentioned that there is an even better way to understand valuation, so this is where Narratives come in, giving you a simple way to attach a clear story about Westlake to the numbers behind your own fair value, revenue, earnings and margin assumptions.
A Narrative on Simply Wall St is your structured view of the company, where you link what you think is happening in Westlake’s business to a specific forecast and a resulting fair value estimate rather than looking at ratios in isolation.
On the Community page, Narratives are presented in an accessible format that lets you see how a company story connects to a financial model. You can then compare the Fair Value from that story with the current share price to help you decide whether the stock looks expensive or inexpensive on your terms.
Because Narratives are updated when new information comes in, such as Westlake’s earnings, litigation developments or analyst revisions, the story and the fair value stay aligned with the latest data instead of becoming stale.
For Westlake, one Narrative might lean closer to the higher Fair Value of about $130.00 with assumptions around stronger earnings improvement. Another might sit nearer the lower Fair Value of about $70.00 with more cautious expectations, and seeing both side by side helps you choose which story, and therefore which valuation, you find more reasonable.
For Westlake, here are previews of two leading Westlake Narratives to make comparison easier:
Fair value: about US$114.29 per share
Potential upside vs. the recent US$87.27 price: roughly 23.7% below this narrative fair value
Revenue growth assumption: about 5.47% a year
- Analysts link a better outlook to HIP demand supported by U.S. infrastructure spending, housing undersupply and balanced exposure across new build and repair markets.
- Cost reduction targets in Performance and Essential Materials, plant optimization and vertical integration are expected to support margins and cash flow if they play out as planned.
- The consensus target of about US$114.29 sits between a bullish US$133.00 and a cautious US$90.00. Agreeing with this view means accepting mid single digit revenue growth, margin recovery and a P/E of about 24x by 2029.
Fair value: about US$70.00 per share
Potential downside vs. the recent US$87.27 price: roughly 24.7% above this narrative fair value
Revenue growth assumption: about 3.91% decline a year
- Plant closures, global overcapacity in key chains and pressure in the PEM segment are flagged as constraints on revenue and EBITDA recovery if weak pricing and demand persist.
- The 3 pillar cost program and HIP guidance are acknowledged, but this view questions how much additional earnings uplift is realistic if cost savings are harder to capture or housing and municipal demand soften.
- This bearish fair value of about US$70.00 assumes relatively flat revenues, modest margin repair and a higher future P/E multiple to justify the price. This implies today’s market expectations may be too optimistic.
These two narratives bracket a fair value range that runs from about US$70.00 to US$114.29. Your own view on Westlake will sit somewhere inside that band depending on how confident you are in HIP driven growth, cost savings in PEM and how long oversupply and pricing pressure last in the core chemical chains.
