What Shriram Pistons and Rings does

Shriram Pistons and Rings, now rebranded to SPR Auto Technologies Limited, is India's largest manufacturer and exporter of pistons, piston rings and engine valves, supplying Indian and international automotive OEMs across passenger vehicles, two/three-wheelers, commercial vehicles, tractors, locomotives and industrial engines. Founded in 1963 (originally as Shama Pistons and Rings) and taken over in 1972 by Dr. Charat Ram, the company is publicly listed on Indian exchanges under the ticker SHRIPISTON (formerly SPRL) and operates 8 manufacturing plants across Ghaziabad, Pathredi, Neemrana, Coimbatore, Pithampur, Noida and Bahadurgarh. Its core technology stack centres on a DSIR-recognised in-house Tech Centre that uses 3D finite element analysis, MAGMA casting simulation, RINGPACK ring dynamic simulation and a transient dynamometer engine-testing facility to enable BS-6 and future-emission-norm-compliant piston, ring and valve design.

The business model is enterprise OEM-direct: long-term negotiated supply contracts with customers including Tata Motors, Maruti Suzuki, Bajaj Auto, Cummins India, Ashok Leyland, VECV, Ford, Nissan, Suzuki, Mitsubishi Heavy Industries, Kirloskar and Swaraj Tractors, generating revenue almost entirely from hardware sales. Diversification has accelerated since 2022: SPR Engenious and EMF Innovations add electric motors and motor controllers from 250W to 300KW for EV applications; Takahata Precision and TGPEL add precision injection moulded parts and metal moulds into electrical, consumer goods and medical segments; the December 2025 acquisition of three Grupo Antolin Indian entities (₹1,670 crore) extends the portfolio into automotive lighting and interior components. Quarterly consolidated revenue reached ₹1,023.20 crore in Q3 FY26 (up 20.67% YoY) on a 20.39% operating margin, supported by ₹1,000 crore of NCD financing in early 2026 and an IND AA+ credit rating.
