Westlake Corporation Overview
Pro stress-test →Westlake is a global manufacturer and supplier of materials and innovative products, headquartered in Houston with operations in Asia, Europe and North America, providing building blocks for vital solutions from housing and construction to packaging, healthcare, automotive and consumer goods. For full year 2025, the company reported net sales of $11.17 billion, operating across two main segments: polymers and advanced materials, and housing and infrastructure products.
Strategic Profile
Pro stress-test →Westlake is undergoing significant operational restructuring. During the fourth quarter of 2025, the company simplified and optimized operations by shutting down three chlorovinyl production facilities and one styrene facility in North America. In January 2026, HIP completed the acquisition of ACI. The company maintains strong liquidity and dividend discipline despite near-term earnings headwinds from lower commodity prices and higher input costs.
Competitive Landscape
Pro stress-test →Westlake competes in the commoditized polymers and specialty chemicals space against integrated manufacturers like LyondellBasell, Dow Chemical, and Eastman Chemical in polymers, and against building products manufacturers like Cornerstone Building Brands and Gibraltar Industries in housing products. The company's integrated model—combining commodity polymers with value-added building products—is relatively unique, providing diversification benefits but also exposing it to cyclical downturns in both end markets simultaneously.
Industry Context
