Negative Impact 4 of 5 earnings Written later

Westlake reported a third-quarter 2025 net loss of $782 million, or $6.06 per share, including a non-cash $727 million charge to write off all goodwill tied to its North American Chlorovinyls unit. Excluding identified items, the net loss was $38 million, or $0.29 per share, compared with net income of $108 million, or $0.83 per share, a year earlier. Shareholders face weaker sales and profit, and the company says cost savings and a plant shutdown should help margins in 2026.

Key points

  • Net sales were $2.8 billion, down from $3.1 billion in the third quarter of 2024.
  • EBITDA excluding identified items was $313 million, compared with $580 million a year earlier.
  • Identified items included the $727 million goodwill impairment and $17 million of accrued shutdown expenses.
  • Management expects about $200 million of cost savings in 2026 and about $100 million of annual losses removed from the Pernis shutdown starting in 2026.
