Karamtara Engineering Limited

Sector: Renewable Energy Equipment & Transmission Infrastructure Manufacturing

1. Overview

Karamtara Engineering Limited is a backward-integrated manufacturer of steel-based products for the renewable energy and transmission lines sectors. Incorporated in 1996, the Company has evolved from a legacy transmission-lines fabricator into what the F&S Report designates as the largest integrated manufacturer in India (by installed capacity) for solar mounting structures and tracker components in Fiscal 2026. The Company offers a diverse product portfolio spanning solar module mounting structures (Solar MMS), tracker piles and piers, torque tubes, lattice transmission towers, wind angular and tubular towers, fasteners and OHTL hardware fittings.

The Company operates 13 manufacturing facilities — eight in Maharashtra (Tarapur MIDC belt), four in Gujarat (Taluka Bhachau, Kutch) and one in Italy (Unit Iselfa) — with an aggregate installed capacity of 889,200 MTPA plus 480,000 pieces (excluding galvanizing), as of March 31, 2026. Its in-house galvanizing capacity of 276,800 MTPA is the largest in the solar energy sector in India per the F&S Report, and two in-house rolling mill furnaces support captive steel section production (angles, channels, beams).

Geographic reach is global: the Company exports to over 50 countries across North America, Europe, Asia, Africa, Australia and Latin America, and is recognized as a Four Star Export House by the DGFT. It serves 16 of the top 24 EPC companies in the United States (~233 GW installed capacity) as of March 31, 2026. Revenue from exports grew at a CAGR of 11.89% from ₹1,395.83 Crores in Fiscal 2024 to ₹1,747.49 Crores in Fiscal 2026.

The Company is led by Promoter Directors Tanveer Singh (Chairman & MD) and Rajiv Singh (Joint MD) — each with ~30 years in the manufacturing sector — supported by CEO & Whole-time Director Sunil Kumar Rustagi (34 years' experience). Consolidated revenue from operations reached ₹4,311.98 Crores in Fiscal 2026 (up from ₹2,425.15 Crores in FY24, a CAGR of 33.34%) with PAT of ₹228.75 Crores (FY24–26 CAGR: 49.28%).

2. Business Model and Revenue Streams

Karamtara operates a B2B integrated manufacturing model targeting OEMs, EPC contractors and Independent Power Producers (IPPs) in the solar, wind and transmission sectors. Revenue is generated primarily via direct product sales through negotiated purchase orders with a mix of domestic and international customers. Recently, the Company has begun undertaking composite contracts covering manufacturing, supply, erection, installation and commissioning of transmission towers, extending its role along the project value chain.

Revenue mix by geography (₹ Crores)

Domestic share has grown sharply from 42.44% (FY24) to 59.48% (FY26), reflecting acceleration in India's solar EPC pipeline; exports grew at 11.89% CAGR versus overall revenue CAGR of 33.34%.

Revenue mix by product line (FY26, ₹ Crores)

Client concentration and repeat business

• Top 10 customers contributed 48.63% of FY26 revenue (FY25: 40.40%; FY24: 63.47%).
• Top 5 customers contributed 31.36% in FY26; largest single customer 7.98%.
• 45.49% of FY26 revenue came from customers associated for ≥2 years.
• Number of solar customers: 48 → 73 → 65 in FY24/25/26; average revenue per solar customer rose from ₹41.31 Crores (FY24) to ₹52.40 Crores (FY26).
• Named repeat customers include Soltec Energías Renovables, Megha Engineering, Ampacity LLC, Gamechange Solar Services India, Waaree Renewable Technologies, Elecnor Servicios y Proyectos, Al Babtain Power & Telecommunication.

Vendor dependency and backward integration

• Top 10 suppliers accounted for 89.65% of total purchases in Fiscal 2026 (FY25: 86.30%; FY24: 76.00%) — indicating rising supplier concentration even as revenue diversifies.
• In-house raw material produced through captive rolling mills was 23.73% of total raw material consumed in FY26 (FY25: 32.54%; FY24: 39.70%) — the falling share reflects volume outstripping in-house steel capacity, which the Company plans to correct with a new Bhachau structural steel profile facility in FY27.

Industry-specific operating metrics

• Fixed asset turnover ratio: 3.70x (FY26) vs 4.92x (FY25) and 4.26x (FY24) — decline reflects heavy Capex ramp-up.
• Net working capital days: 43 days (FY26) vs 67 days in prior two years — sharp improvement.
• Customer rejection rate: 0.14% (FY26) — near-negligible, testifying to quality controls.
• Long-term credit rating: IND A+/Stable (upgraded from IND A/Stable in July 2025 by India Ratings).
