Westlake Corporation (WLK) scored on five pillars from its reported financial statements, and ranked against 77 Materials companies.
Westlake Corporation (WLK) scores 2.4 out of 10 as of , computed from its reported financial statements. That reads as low quality. The reading rests on solvency, and profitability is what holds it back.
One pillar, growth, is unscored because the filings behind it carry too little to judge. It is shown as a dash rather than a zero, and the overall score is the weighted average of what could be scored.

We cannot judge Westlake Corporation yet, because fewer than five years had both a return on capital and a cost of capital we could measure. This is not a “no”.

Westlake Corporation (WLK) has a Lemma Quality Score of 2.4 out of 10 as of October 19, 2026, which reads as low quality. A low reading means the reported numbers show weakness on several pillars at once, which is a reason to understand the business before anything else. Five pillars feed it, and every one of them is computed from what the company reported rather than from its share price.
Among the 77 Materials companies with a published score, that ranks at the 14th percentile, among the weakest quarter of its peers. For reference, the middle of the group scores 4.4 and a company needs 6.2 to reach its top quarter, which leaves Westlake Corporation well below the median.
Westlake Corporation’s profitability score is 0.5 out of 10 (weak). Against a median of 4.4 among 74 Materials companies, that is well below the group and the 11th percentile. Weak profitability means the business converts less of its sales and capital into profit than its peers, which can come from thin pricing power, high costs or a temporary squeeze.
Solvency scores 4.2 out of 10, which reads as average. The median across 66 Materials companies is 6.7, so Westlake Corporation is well below its peers on this pillar and ranks at the 26th percentile. Leverage in the middle of the range is rarely a problem in good years, and it is worth watching how quickly it would tighten in a weak one.
There is no growth score for Westlake Corporation: too little of the pillar could be measured from the filings to give an honest reading. The overall is therefore the weighted average of the other pillars. Across 57 Materials companies the median for this pillar is 3.2. Growth needs at least three years of comparable annual statements, so a short or interrupted history leaves it blank.
Westlake Corporation’s efficiency score is 2.5 out of 10 (weak). Against a median of 5.2 among 71 Materials companies, that is well below the group and the 14th percentile. Poor conversion of assets and earnings into cash can come from heavy investment phases, and it matters whether that investment is paying off.
On predictability, Westlake Corporation scores 2.8, a weak reading. Its peers have a median of 4.5 across 76 Materials companies, which places it well below them, at the 28th percentile. A low predictability score often belongs to cyclical businesses, where good and bad years alternate with the economy or with commodity prices.
This is a lopsided profile. Solvency scores 4.2 but profitability only 0.5, a gap of 3.7 points, so the overall hides a business that is excellent in one respect and weak in another. A solvency lead means the balance sheet is the company’s strongest asset, a cushion that buys time when trading gets harder. A profitability shortfall is the one most worth understanding, since it bears directly on whether the business creates value.
Closing the gap on profitability would do the most for the overall. At the median of Materials companies, 4.4, Westlake Corporation would score about 3.6 instead of 2.4. Only four of the five pillars could be scored. Together they carry 80 of the 100 weight points (the full set is profitability 25, solvency 20, growth 20, efficiency 15, predictability 20), and the overall is the weighted average of those alone.
These are the Materials companies closest to Westlake Corporation in market value. Each has its own page scored on the same five pillars, so the comparison is like for like.
How much profit the company generates from its capital and sales.
The company’s ability to service debt and meet its obligations.
How fast revenue, earnings and cash flow are compounding.
How well assets and earnings convert into cash and output.
How stable and consistent results have been over time.
Each metric is scored from 0 to 10 against sector-aware benchmarks, where higher is better. Metrics roll up into five pillars, and the pillars combine into the overall score using the weights shown. Sector-sensitive metrics are judged relative to peers in the same sector.
This score is a systematic, backward-looking read of reported fundamentals. It does not judge valuation, management quality, competitive moat, or future prospects, and can be distorted by one-off items or unusual accounting. Treat it as a starting point, not a recommendation.

Westlake Corporation ranks at the 14th percentile of the 77 Materials companies Lemma publishes a score for. The median there is 4.4 and the top quarter starts at 6.2, against Westlake Corporation’s 2.4.
Five pillars, each scored from 0 to 10 against sector-aware benchmarks and then weighted into one overall reading: profitability, solvency, growth, efficiency and predictability. Everything comes from reported financials, and nothing comes from price, sentiment or forecasts.
This page last changed on October 19, 2026. The score moves with the financial statements, so the page changes when a new filing moves the reading rather than on a schedule. Live figures for WLK are in the app.
No. Quality and valuation are separate questions, and a good business at the wrong price is still a bad purchase. Score the business here, then price it with a DCF you control.
Inside Lemma Analysis the same five pillars run on every company we cover, with the metrics behind each one, current fundamentals, a DCF you control and a watchlist that tells you when the price catches up.
