Company Profile



Pragstrasse 26-46, 70376 Stuttgart, Germany

Business Overview

-The Company supplies systems and components for the automotive industry focused on powertrain, filtration and thermal management technology. In addition, the Company has started expanding its development into electric mobility.

-As of December 31, 2019, the Company is organized into the following five business units in addition to a Mechatronics division and six profit centers:

  • Engine Systems and Components
  • Filtration and Engine Peripherals
  • Thermal Management
  • Aftermarket

-On January 1, 2020, the Company established a new Electronics and Mechatronics business unit comprised of the Company’s competences in mechatronics, electric motors, electronics as well as a profit center for compressors.

-Since its establishment in 2013, the Company's Thermal Management business unit has grown at a significantly faster pace compared to the other business units within the Company, while also emerging as the largest business unit for the Company. The rapid growth of the business unit stems from acquisitions of various businesses including the majority share of Behr in 2013 and the Delphi Thermal business unit in 2015. However, the Company’s Mechatronics division, created in 2016, has outpaced the other business units, growing in sales even as the other business units had declining sales. In the fiscal year ended December 31, 2019, the Thermal Management business unit had sales of EUR 4,556.6 million, a decrease of 1.6% from the previous year. The percentage decrease in the Thermal Management business unit was less than the year-to-year sale declines in the Engine Systems and Components Business Unit and the Filtration and Engine Peripherals Business Unit, as well as the Company’s sales as a whole. However, the Mechatronics division’s sales increased by 8.6% compared to the previous year, the largest percentage gain in any of the Company’s business segments. The Thermal Management business unit's sales comprised approximately 37.8% of the Company's total sales in the 2019 fiscal year, compared to the Mechatronics division’s 4.1%.

*While the Mechatronics division was not created until 2016, the Company has sales figures of the division starting from 2015. Sales of the Mechatronics division prior to the points shown on the graph are integrated into the Others category.
