Westlake Has Built Resilience Through Forward Integration

Westlake's core strategy focuses on forward integration: It begins with ethylene and chlor-alkali production, moves through PVC resin, and ultimately captures margin in finished building products such as vinyl siding, pipe, and fittings. We view this as a sound strategic posture. It doesn’t confer a durable competitive advantage, but it improves earnings quality relative to a pure commodity chemical producer and partially insulates the firm from fluctuations in PVC supply conditions.
