1. At a Glance
Subros sells cooling. The three months to June 2026 brought ₹1,032.11 crore of it. That is 17.52% more than the same period a year earlier.
Operating profit went the other way, from ₹82.01 crore to ₹80.80 crore. Profit after tax reached ₹41.52 crore, against ₹40.83 crore before. The move was 1.69%, which in percentage terms is one shuffled step to the left.
Management described the quarter as “eventful”. The list, from the company’s post-results call with analysts: geopolitical tension, crude volatility, shipping disruption and forex swings. Closer to home, management named a state election and seasonal labour migration. Minimum wages were revised by roughly 30–32% in Haryana. In Uttar Pradesh the revision was 26–28%. Management called those revisions extraordinary and unbudgeted.
The quarter also brought a Technical Assistance Agreement with DENSO Corporation, Japan and Toyota Industries Corporation, Japan. It covers local manufacture of electric compressors at Karsanpura, Gujarat. A DENSO nominee director changed. Truck air-conditioning revenue grew 77% year-on-year. Management attributes that base to the government’s cabin air-conditioning mandate for N2 and N3 trucks, the goods vehicles above 3.5 tonnes.
For a company whose whole job is keeping things cool, the quarter ran warm on inputs. Material cost moved to 73.79% of net sales, from 71.80%. Employee cost sat at 10.05%. The investor presentation puts the EBITDA margin at 8.47%, from 10.02%. That margin is the share of sales left before interest, tax and depreciation.
Behind the quarter sits the full year. Revenue for the twelve months to March 2026 was ₹3,755.52 crore. Profit after tax was ₹165.65 crore.
2. Introduction
Subros was incorporated in 1985 as a joint venture between three parties. The Suri family of India, Denso Corporation of Japan and Suzuki Motor Corporation of Japan agreed on roughly one thing. Indians would eventually want their cars cold.
Four decades later the ownership arithmetic has barely twitched. The Suri family holds 36.79% and Denso 20%. Suzuki holds 11.96%. The shareholding pattern for the last twelve quarters shows promoter holding at 36.79% in every column. Promoters are the founding owners of the company. Twelve columns and one number is not a common sight in a spreadsheet.
The company makes and supplies air-conditioning products to large makers of passenger and commercial vehicles. It works under a technical collaboration with Denso. The investor presentation puts its share at 41% of passenger car air-conditioning and 41% of truck aircon and blower. The same presentation calls Subros the largest air-conditioning and thermal products company in India.
ICRA, a credit-rating agency, notes an equity infusion of ₹209.9 crore from Denso in December 2018. That means fresh shares issued for cash. ICRA says the money went towards part repayment of debt and creditors. Borrowings were ₹404.42 crore in March 2017. By March 2026 they were ₹30.01 crore. Interest cost over the same stretch fell from ₹47.91 crore to ₹9.63 crore. The finance-cost line has been shown the door, with a small farewell gift.
The recent chapter is capacity. ICRA notes a greenfield plant at Kharkhoda, meaning a new site built from open ground, at an estimated ₹150 crore. ICRA had it planned operational by June-July 2026. The August call with analysts placed construction at an “advanced stage of completion”. Management targets start of production in the three months to December 2026. The first phase is sized at roughly 4.75 lakh units, and the second adds the same again.
At Karsanpura, ₹175 crore goes to an electric compressor line of 400,000 units. Management has it commissioned by March 2028, and three-quarters of the spend is debt-funded. A further ₹90 crore from internal accruals adds 500,000 units of conventional engine compressor capacity. Internal accruals are profits kept inside the business. Management puts that addition within 24 months. In January 2026 the company disclosed an order for localised electric compressors. It is worth ₹1,280 crore over seven years. A separate ₹52.18 crore order from Indian Railways covers cab HVAC maintenance over three years.

3. Business Model: WTF Do They Even Do?
Subros makes cold air and the machinery that produces it. The range runs to compressors, condensers, evaporators and hoses. Tubes, radiators, blower units and complete HVAC systems come out of the same plants. HVAC stands for heating, ventilation and air conditioning.
It is a fully integrated thermal products manufacturer. In practice it does not bolt someone else’s cooling box into a car. It makes the box, the tubes going into the box, and the thing that spins inside it.
The end markets share little with one another except temperature. Cars, buses, trucks and tractors are four of them. Reefer units, railway coaches and home air conditioners are the rest. Reefer units are the refrigerated boxes carried on lorries and containers. One order book covering a hatchback dashboard and a railway cab rests on a single physical principle. Heat must go somewhere else.
Customers include Maruti Suzuki, Tata Motors, Mahindra & Mahindra and Renault Nissan. BHEL, Denso, Haier and Voltas also buy. So do Havells and Daikin. ICRA, the credit-rating agency, discloses the concentration plainly. It puts sales to Maruti Suzuki at 80–85% of revenues, including indirect sales. That holds for the year to March 2025 and the six months to September 2025.
