History of Westlake
- Founded: 1986
- Founders: T.T. Chao
T.T. Chao founded Westlake Chemical in Houston in 1986, building petrochemical capacity before the 2004 IPO and decades of acquisitions.
The 2016 Axiall acquisition transformed the vinyls position, and building-products purchases including Boral's North American business created the Housing and Infrastructure segment.
The 2022 rename to Westlake Corporation reflected the broadened scope, and Gilson's 2024 arrival marked the first outside CEO.
