Sundram Fasteners reported revenue grew 18% to Rs. 1,359 crores (US$150.85 million) across OE and aftermarket segments. Despite export challenges from tariff pressures, the company maintained healthy margins and reported nine-month profit after tax of Rs. 401 crores versus Rs. 382 crores previously.

The domestic growth was driven primarily by strong performance in commercial vehicles, passenger cars, multi-utility vehicles, and tractors. Management indicated that all three key segments - M&HCV, cars and MUVs, and tractors - contributed to the robust domestic performance.

Export operations faced headwinds due to tariff pressures, with some products experiencing 25% tariffs while others faced 50% rates depending on iron and steel content. This impacted the company's contribution margins, though the business maintained operational efficiency.

The company is expanding its non-automotive portfolio to 38% of revenues through wind energy, aerospace, and railway fasteners growth, while targeting 18% EBITDA margins and double-digit revenue growth for fiscal 2027.
