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.

Westlake said it began consultations with works councils on June 13, 2025, over ceasing operations at its entire Pernis, Netherlands, facility in 2025, citing continued deterioration of its European business. The company expects total pre-tax closure costs of about EUR 190 million and a further workforce reduction of about 230 employees, with a charge for substantially all of these costs in the second quarter of 2025. Cash outflows will continue for several years after closure, and the amount and timing of some costs remain uncertain, so shareholders face a large near-term charge and continuing spending.
