Westlake (WLK) Shuts Cologne PVC Plant, Is The Stock A Bargain?
Westlake (WLK) is back in focus after the company moved to close its polyvinyl chloride plant in Cologne, Germany. The step comes with sizeable charges and a reset of its European footprint.
Recent trading reflects that repositioning. Westlake’s share price has fallen 16.7% over the past month and is down 14.4% year to date, while the 1-year total shareholder return is lower by 20.8%, which points to fading momentum despite management’s push to cut higher cost capacity.

Bulls see Westlake using painful restructuring to set up a cleaner, more profitable PVC base. Bears see a shrinking footprint and heavy charges. Which story fits the current valuation?
Most Popular Narrative: 31% Undervalued
Against a last close of $63.50, the most followed narrative puts Westlake’s fair value near $92.31, which implies a sizeable valuation gap built on its assets, cost base and end market mix.
Westlake continues to benefit from having around 85% of Performance and Essential Materials production tied to North American natural gas and NGL feedstocks, which were largely unaffected by the recent oil price spike. This allowed a 21% sequential average sales price increase in Q2 2026 to flow through to margins and supported future earnings sensitivity to global polyethylene, caustic soda and PVC pricing.
See why 9 investors see Westlake as 31% undervalued.
Result: Fair Value of $92.31 (UNDERVALUED)
Still, if global oversupply keeps pressuring Performance and Essential Materials pricing or if higher feedstock costs return, the current Westlake upside narrative could unravel quickly.
