Westlake Corporation Announces Plant Closures and Profitability Improvement Plan
WLK
Guidance Update
New Projects/Investments
Demand Weakening
- Westlake Corporation is closing four higher-cost North American chlorovinyl and styrene assets by the end of 2025 to address global overcapacity and low-priced export markets, which have led to unacceptable earnings in its PEM segment.
- These optimization actions are projected to deliver an annual EBITDA benefit for PEM of approximately $100 million and an additional $75 million in cash savings from avoided capital spending, resulting in total free cash flow savings of approximately $175 million, all starting in 2026.
- The company anticipates incurring total pre-tax charges of approximately $415 million related to the closures, with approximately $357 million attributed to non-cash accelerated depreciation, amortization, and asset write-offs, largely recognized in Q4 2025.
- The closures will reduce Westlake's global chlorovinyl capacity by between 11% and 15%.
- For the fourth quarter of 2025, Westlake expects PEM's EBITDA to be between $125 million and $150 million lower than the third quarter of 2025, excluding identified items.
