Westlake Corporation
Westlake Corporation manufactures and markets performance and essential materials, and housing and infrastructure products in the United States, Canada, Germany, China, Mexico, Brazil, France, Italy, and internationally. It operates through two segments, Performance and Essential Materials and The Housing and Infrastructure Products. The Performance and Essential Materials segment offers ethylene, polyethylene, chlor-alkali, chlorinated derivative products, ethylene dichloride, vinyl chloride monomer, polyvinyl chloride (PVC), epoxy specialty resins, and base epoxy resins and intermediaries. The Housing and Infrastructure Products segment provides residential PVC sidings; PVC trim and mouldings; architectural stone veneers; windows; PVC decking; polymer composite and cement roof tiles; PVC pipes and fittings for various water, sewer, electrical, and industrial applications; and PVC compounds for various housing, medical, and automobile products. This segment also offers consumer and commercial products, such as landscape edging; industrial, home, and office matting; marine dock edging; and masonry joint controls. It offers its products to chemical processors; plastics fabricators; small construction contractors; municipalities; and supply warehouses for use in various consumer and industrial markets, including residential construction, flexible and rigid packaging, automotive products, healthcare products, water treatment, wind turbines, and coatings, as well as other durable and non-durable goods. The company was formerly known as Westlake Chemical Corporation and changed its name to Westlake Corporation in February 2022. Westlake Corporation was founded in 1986 and is headquartered in Houston, Texas. Westlake Corporation is a subsidiary of TTWF LP.
What does it do?
Westlake Corporation makes the basic chemical building blocks that go into everyday products you use without thinking about. They produce PVC — the plastic in your pipes, window frames, and vinyl flooring. They also make chlorine-based chemicals and polyethylene, which is the plastic in food packaging and grocery bags. Think of them as a behind-the-scenes supplier to construction and manufacturing industries across the US, Europe, and Asia.
Westlake sits at the intersection of two massive spending trends: housing construction and infrastructure repair. When governments push infrastructure bills or housing starts pick up, demand for PVC pipes and building materials spikes — and Westlake benefits directly. Right now, chemical companies like Westlake are under pressure from weak demand and falling prices, making this a closely watched recovery story.
How does it make money?
Westlake splits its business into two parts. The first — Performance and Essential Materials — makes industrial chemicals like ethylene, PVC, and chlorine derivatives, which it sells to manufacturers. The second — Housing and Infrastructure Products — sells finished building materials like pipes, fittings, and window profiles directly to the construction market. The company brought in $11.2 billion in revenue last year, down from $12.1 billion the prior year, reflecting a tough pricing environment across the chemical industry.
Why do investors care?
The bull case for Westlake is a recovery in chemical pricing and a rebound in housing and infrastructure spending. When building activity picks up, demand for PVC and related materials rises, and margins — which have been crushed recently — could bounce back sharply. The company also has a global footprint across the US, Europe, and China, giving it multiple levers to pull. For investors, the question is simple: how long does the downturn last, and is $81 a cheap entry point before the cycle turns?
