With effect from February 1, 2021, MAHLE has taken over the air conditioning business in Japan, Thailand, and the USA from the former Keihin Corporation (now Hitachi Astemo, Ltd.). The antitrust authorities have given their approval. Four production sites (of which two are in Japan, one each in Thailand and USA) and one development center are now being integrated into the MAHLE Group. With this acquisition, MAHLE is strengthening its position in the field of air conditioning systems. This is one of the strategic future fields of the group.
