As of the second quarter of 2026, electrified (xEV) products accounted for 31% of total revenue, helped by higher European volumes. Its customer base spans Korean automakers including the Hyundai Motor Group as well as major North American and European OEMs.
According to DS Investment & Securities, second-quarter volumes to Mercedes-Benz rose 36% year on year and to BMW 19% in Europe, while the Americas fell 6.0% to KRW 806 billion and Korea fell 2.0% to KRW 782 billion.

Since the group transition, execution-focused regional business groups have been created for Asia-Pacific, China, the United States and Europe, with sales, product planning, production, quality, purchasing and finance functions transferred from global headquarters, alongside consolidation of overseas plants.
Competitively, the company bids for global platform awards against large Japanese and European thermal management suppliers, where system integration capability and cost competitiveness are decisive.
Management is also pushing into non-automotive areas such as data center liquid cooling and energy storage system thermal management, and set up a dedicated global aftermarket organization in January 2026.
