Westlake Corporation

Westlake Corporation is a global manufacturer and marketer of housing and infrastructure products, and performance and essential materials. The company's products, including some of the most widely used materials globally, serve diverse consumer and industrial markets such as residential construction, flexible and rigid packaging, automotive, healthcare, water treatment, wind turbines, coatings, and other durable and non-durable goods. Westlake operates through two main segments: Housing and Infrastructure Products (HIP) and Performance and Essential Materials (PEM). The company is vertically integrated along its materials chain, with significant downstream integration from ethylene and chlor-alkali (chlorine and caustic soda) into vinyls, polyethylene (PE), and epoxy. It also has substantial downstream integration from polyvinyl chloride ("PVC") into its HIP segment for residential building products, PVC pipe and fittings, and PVC compounds. Westlake began operations in 1986. In 2014, it formed Westlake Chemical Partners LP ("Westlake Partners") to operate, acquire, and develop ethylene production facilities and related assets, and Westlake Partners completed an initial public offering of common units in the same year.
