Karamtara Engineering is opening a ₹875 Cr IPO on September 9, 2026. Most of its product lines run out of a single dedicated factory and it is India’s largest integrated manufacturer of solar mounting structures and tracker components by installed capacity.
IPO Summary
Industry Overview
India’s power sector is shifting from coal to renewables.
As of March 31, 2026, renewable and non-fossil fuel sources crossed 53% of the country’s installed generation capacity as India pursues 500 GW of renewable capacity by 2030.
Karamtara Engineering is a backward-integrated manufacturer of solar structures, transmission towers, wind towers, and fasteners for domestic and export markets. In short, it makes products and structures that support solar panels, transmission cables, and wind turbines.
Business Model Explained
Karamtara Engineering is the largest manufacturer (by installed capacity) of solar mounting structures and tracker components in India in FY26.
The product range spans four categories:
- Solar energy products, comprising fixed-tilt module mounting structures and tracker piles, piers and torque tubes, made up 79% of FY26 revenue.
2. Revenue from transmission lattice towers has nearly tripled as India’s transmission capacity gets built out.
- Fasteners used across solar, wind, transmission, and automotive applications.
- The remainder came from wind-turbine towers, a business the company entered in FY25.
As of March 31, 2026, the company operated 13 manufacturing facilities: eight in Maharashtra, four in Gujarat, and one in Italy, with one upcoming facility in Saudi Arabia.
Backward integration is an important pillar of their model: in-house facilities let the company convert raw steel into finished, coated structural components without relying on third-party processors.
However the share of raw material produced in-house actually declined from 40% in FY24 to 24% in FY26, as purchased volumes grew faster than in house capacity.
Customers are original equipment manufacturers (OEMs), engineering, procurement and construction (EPC) firms, and independent power producers (IPPs).
The company says it serves 16 of the top 24 EPC companies in the United States by installed capacity, and exported to over 50 countries as of March 31, 2026.
Unit Economics Per-Tonne
Revenue per tonne rose 13% between FY25 and FY26, but part of that gain is optical:
It contains pass-through US tariff recoveries into revenue from operations, and these recoveries jumped from ₹48 Cr in FY25 to ₹577 Cr in FY26. This is a cost neutral entry as explained in financials section.
EBITDA per tonne, which is not affected by this entry, rose by 12% over the same period which gives a clear read on underlying pricing and cost control.
Operating Metrics
- Revenue by Product Category: Solar products still dominate at 79% of FY26 revenue, but wind towers which started this year contributed ₹135 Cr in FY26. Lattice tower revenue nearly tripled from FY24 to FY26, as India’s transmission capacity gets build-out.
*Others includes OHTL hardware fittings, engineering and service fees, job work, sale of raw materials and scrap, and export incentives.
- Revenue by Geography: Domestic revenue grew faster than exports in every year shown, more than doubling from FY24 to FY26. While US revenue grew a slower 27% over the same period it still accounted for 34% of FY26 revenue.
The Financial Stuff: Revenue to PAT
- Revenue grew 33% a year on average between FY24 and FY26, and PAT grew faster at 49% a year, so margins widened as the company scaled.
The one anomaly worth flagging is the sudden increase in the expenses and revenue lines.
Most of that jump is a pass-through:
The US tariffs introduced in the fourth quarter of FY25 generated ₹577 Cr of tariff-related expenditure in FY26 which is recognised under other expenses, with a matching recovery (gain) recognised as revenue. This optically inflates the revenue & cost as well. However, these cost-neutral entries do not affect PAT and EBITDA.
Karamtara’s Peers — FY26
- At ₹4,312 Cr, Karamtara’s FY26 revenue sits in the middle of this peer set, larger than KP Green Engineering but smaller than Waaree, Suzlon or Premier Energies.
- Its return on net worth of 21% beats only Inox Wind’s 8% among the eight peers; the rest post RoNW above 30%.
Key Risks
- Export and US tariff exposure.
Exports made up 41% of FY26 revenue, with the United States alone at 34%. Any changes in international trade policy, tariffs or export controls can materially affect the company’s financials. - Manufacturing concentration in Maharashtra.
Facilities in Maharashtra generated 91% of FY26 revenue. So any unscheduled slowdown or shutdown at one site could materially affect that entire product category.
Conclusion
Karamtara Engineering has grown its revenue alongside the booming renewable infrastructure sector. While Its backward-integrated model and market leadership in solar mounting structures provide a clear operational foundation.
