Hemlock Semiconductor Completes Transition to New Chairman & CEO

Arabinda ‘AB’ Ghosh assumes roles after distinguished career at Akzo Nobel, Nouryon

HEMLOCK, Mich. – Hemlock Semiconductor Operations (HSC), the nation’s largest manufacturer of hyper-pure polysilicon used in solar panels and semiconductors, today announced that Arabinda “AB” Ghosh has formally begun his role as the company’s new chairman and CEO, succeeding Mark Bassett, who retired December 31, 2021. Hemlock
announced the transition on September 27, 2021, when Ghosh started at HSC as Chief Operating Officer.

Ghosh joined HSC after a distinguished career as a senior executive with Akzo Nobel and Nouryon, global leaders in specialty chemical and coatings manufacturing, where he led business units with revenues of up to $2.4 billion, more than 50 plant locations in multiple countries and more than 6,000 employees.

“I have been excited to work with the HSC team, which has built the company into a foundational building block in the semiconductor and solar energy supply chains,” said Ghosh. “We see both markets – especially solar energy – growing at a tremendous rate.

“As demand for HSC’s hyper-pure polysilicon increases due to a range of factors, HSC will look to expand and hire new workers for our plant in Hemlock, Michigan,” Ghosh added. “We have production capacity in Michigan that can be used to really build a resilient U.S. supply chain for these industries, especially the solar energy industry. We want to be best-in-class manufacturing in terms of quality, in terms of safety, and in terms of cost.”

Bassett retired as HSC’s Chairman and CEO after five and a half years. Under his leadership, HSC solidified its place as the country’s largest manufacturer of hyper-pure polysilicon, a critical material used in the solar, semiconductor and battery storage industries.

Ghosh and his wife, Tracy, are in the process of relocating from Georgia to their new home in Midland, Mich. The couple has two adult sons. A headshot of AB Ghosh can be found here.
