The story

Since 2005, Gentherm has been partnering with BMW and Ford on a project that is backed by the U.S. Department of Energy focused on the development of an automotive thermoelectric generator (ATEG) that converts waste exhaust heat into electrical power based on the Seebeck Effect. A prototype of the ATEG was named one of the most promising innovations for 2012 by Car and Driver magazine.

Amerigon, the precursor company to Gentherm, had been formed in 1991 by Lon E. Bell in Monrovia, California, focusing on automotive technologies and electric vehicles. In 1999, the company introduced the first thermoelectric Climate Control Seat (CCS) for the MY 2000 Lincoln Navigator, and in 2005, the company relocated from California to Northville, Michigan. In 2008, Amerigon acquired Comair Rotron Shanghai; in 2011, they acquired a majority stake in W.E.T. Automotive Systems, a manufacturer of thermal comfort products. Amerigon Incorporated officially changed its name to Gentherm Incorporated on June 13, 2012. The company's NASDAQ trading symbol changed from "ARGN" to "THRM" simultaneously. The rebranding reflected the company's focus on its thermal management technologies.

Gentherm has 30+ locations and 14,000+ employees in the following countries: China, Czech Republic, Germany, Hungary, Japan, Mexico, Morocco, North Macedonia, South Korea, Ukraine, United Kingdom, United States, and Vietnam.
