What Subros does

Subros Limited, founded in 1985 as a joint venture between the Indian Sur family (promoters), Denso Corporation (Japan, 20% stake), and Suzuki Motor Corporation (Japan, 11.96% stake), is India's largest dedicated manufacturer of automotive thermal management systems. The company designs and produces compressors (swash plate and rotary vane), HVAC units, condensers, evaporators, radiators, heaters, and refrigerant tubes and hoses for passenger vehicles, commercial vehicles, off-highway equipment, railways, transport refrigeration, and residential/commercial cooling. Manufacturing is concentrated across eight plants in Noida, Manesar, Karsanpura, Chennai, Pune, and Nalagarh, with three technical design centers including the Subros Technical Centre (STC) and the joint Denso Subros Engineering Centre (DSEC).

The company is pivoting decisively toward electrified mobility, with a ₹175 crore electric compressor programme targeting 70% localization and ₹250 crore peak annual revenue, a ₹1,280 crore supply award from Maruti Suzuki spanning seven years, and battery thermal management systems for electric buses and hydrogen-cell bus applications. Beyond EV components, Subros runs long-cycle maintenance and supply contracts with Indian Railways and operates an India-wide dealer network for aftermarket parts across passenger and commercial vehicle segments.

Revenue is generated almost entirely through B2B OEM supply under multi-year negotiated contracts supplemented by aftermarket parts sales, railway service contracts, and a smaller residential and commercial AC business. FY26 revenue reached ₹3,755.52 crore (up 11.52% YoY) with net profit of ₹165.78 crore, and the company is publicly listed on the BSE under ticker SUBROS, with Indian promoters retaining roughly 36.79% ownership and Maruti Suzuki/Suzuki/Denso acting as both shareholders and anchor customers.
