India's quiet export machine: how mid-cap engineering firms doubled overseas revenue in 18 months

For two years, the export story in India has been told through services — GCCs, IT, fintech rails. The data tells a different story.

What the filings say

Across 47 mid-cap engineering and capital-goods firms with March-ending fiscals, overseas revenue grew 103% between FY23 and the trailing-twelve-months ending December 2024. The same cohort grew domestic revenue 18%.

These are not household names. They make precision-machined components, industrial valves, hydraulic systems, and forged parts that end up inside European wind turbines and American oil rigs. Twelve of them now derive more than half their revenue from outside India.

"We stopped pitching ourselves as the cheap option in 2022," one founder told us. "The pitch now is reliability and lead times. Cost is the third bullet."

Why this matters

India's services-led export narrative has policy consequences. PLI extensions, infrastructure spend, FTA negotiations — all are weighted toward sectors the data says are no longer the only growth engines.

The Business Index's read of audited filings, customs data, and management commentary suggests the next five years of export growth will be disproportionately driven by sub-₹5,000 crore market-cap manufacturers. Most of them have no equity research coverage.

What to watch

• Order books at Bharat Forge, AIA Engineering, and Grindwell Norton — used here as proxies for the cohort.
• Container freight rates on the India–Northern Europe route.
• Any softening in the US capex cycle through Q3 2025.

The shift is real. It's just not where everyone is looking.
