Westlake’s Q2 rebound, low-cost feedstock moat, and downstream infrastructure expansion create substantial five-year upside, but housing, chemical-cycle, execution, and leverage risks warrant a recovery-oriented valuation.
Overview
Westlake is a globally integrated chemical and building-products manufacturer organized into PEM and HIP. Its competitive foundation is low-cost North American ethane and natural gas, vertical integration from chlorine and ethylene through VCM and PVC resin, and downstream conversion into branded and specified products. The company is the #2 global PVC and chlor-alkali producer, the #2 LDPE producer in the Americas, and the world’s largest specialty autoclave LDPE producer. **Q2 2026 marked a sharp recovery:** sales rose 10.8% year over year to $3,271 million, net income reached $260 million or $2.01 per diluted share, and EBITDA increased to $679 million with a 21% margin. PEM led the rebound, while HIP remained resilient but saw margin compression to 22%. Management has realized $300 million of its $600 million 2026 profitability target. **Near-term catalysts** include the Wichita Falls PVCO startup, ACI integration, easing Chinese PVC exports, and further cost savings. The principal counterweights are soft housing, leverage, environmental liabilities, and cyclical chemical pricing. Analysts’ targets range from $80 to $117, with consensus near $100.62.
