NEW YORK (ICIS)–US-based chemical and building materials producer Westlake Corp has appointed Jean-Marc Gilson as president and CEO, effective 15 July. He succeeds Albert Chao, who becomes executive chairman of the Westlake board of directors.
Gilson most recently served as president and CEO of Japan-based Mitsubishi Chemical Group from 2021 until March 2024. From 2014-2020, Gilson served as CEO of France-based Roquette, a family-owned global leader in plant-based ingredients and a leading provider of pharmaceutical excipients.
James Chao, the current chairman of the board, will become senior chairman. All these appointments take effect 15 July.
“I am excited to welcome Jean-Marc as the newest addition to Westlake’s management team. Westlake is in a very strong position supported by a world-class team, and, having served as the CEO of Westlake for the last 20 years, now is the right time to implement our succession plan,” said Albert Chao, who noted Gilson’s 25 years of executive experience in the chemical industry in the US, Europe and Asia.
“I am honored and humbled to become the second, and first non-family, CEO of Westlake,” said Gilson.
“I have long admired Westlake as a best-in-class company at the forefront of delivering life-enhancing products through innovation in essential materials and building products,” he added.
Jean-Marc Gilson also becomes president and CEO and a director of Westlake Chemical Partners GP LLC, the general partner of Westlake Chemical Partners LP. Albert Chao will become executive chairman and James Chao will become senior chairman of the Westlake Chemical Partners GP LLC board of directors.
UBS analyst Joshua Spector said the timing comes as a “bit of surprise”. The Chao family owns around 75% of Westlake Corp, and Gilson’s 25 years of experience skews towards specialty chemicals, he noted.
Key questions will be around Westlake’s strategy and commitment to growing the building products business, Spector added.
