Stelmec Limited (STL) was incorporated in Mumbai on 29 February 2000, converting to a public limited company in July 2007 and absorbing its associate partnership firm, Stelmec Switchgear, in 2005 . The company is an established player in India's electrical equipment sector, manufacturing medium-voltage switchgear — including Indoor VCB Panels, Outdoor VCB Kiosks, HV & EHV Disconnectors, Relay Panels, and Bus Ducts — and providing full EPC services for high-voltage substations and transmission and distribution lines . Revenue is tender-driven, with customers concentrated among state utilities and infrastructure developers . STL operates three manufacturing units — one in Gujarat and two in Thane, Maharashtra — and maintains a Pan-India sales network across major states . International expansion remains aspirational, with recent fundraising earmarked partly to strengthen overseas presence .
Stelmec operates across three distinct segments — Electrical Power Products, EPC Services, and Smart Grid & Power IT Solutions — with manufacturing-led Power Products forming the core revenue base and the two project-based verticals added to capture India's expanding grid investment cycle .
Electrical Power Products
The flagship segment manufactures a broad range of switchgear and protection equipment across voltage classes :
- MV switchgear: Indoor VCB Panels, Outdoor VCB Kiosks, and Outdoor VCBs
- HV & EHV Disconnectors; LV and HV Switchgears
- Relay Panels (11kV–400kV), Bus Ducts, Distribution Panels, and Control Panels
- LT/HT Metering Panels, LT Distribution Boxes, and Numerical & Electromechanical Relays
Products are sold on a transactional (unit-sale) basis to utilities, industrial customers, and government bodies . The RMU Ring Main Unit, SPCV Porcelain Clad Outdoor Vacuum Circuit Breaker, and SIVP12 12kV AIS VCB Panel represent key product lines within this segment .

EPC Services & Smart Grid & Power IT Solutions
The EPC segment delivers end-to-end project contracts for power infrastructure, operating on a project-based model . The Smart Grid & Power IT Solutions segment executes deployments in AMI/AMR and SCADA systems, also on a project-contract basis . Both verticals were strategically added to expand Stelmec's addressable market beyond equipment manufacturing . Segment-level revenue contribution percentages are not publicly disclosed ; consolidated revenue reached ₹1,042 Cr in FY2025, up from ₹755 Cr in FY2024 . The breadth of the product and services mix positions Stelmec to participate across the full power sector value chain, a competitive differentiator examined further in the financial performance section.
Stelmec delivered a sharp inflection in FY2025, with revenue reaching ₹1,042 Cr — a 38.1% YoY surge — capping a 9.3% revenue CAGR over FY2021–FY2025 . The growth trajectory was subdued in FY2022–FY2023 before re-accelerating sharply in FY2024 (₹755 Cr ) and FY2025.
The Growth & Margin History table below details revenue, EBITDA, EBIT, and PAT across all five years alongside their respective margins.

Margin Trajectory
EBITDA margins were range-bound at 4.5–5.0% from FY2021 to FY2023 , then expanded decisively to 7.1% in FY2024 and 10.8% in FY2025 , reflecting a 32.0% EBITDA CAGR — triple the pace of revenue growth. PAT margin followed the same trajectory, recovering from 1.5% in FY2023 to 6.6% in FY2025 , with PAT growing 215.5% YoY to ₹68 Cr .
The Margin profile chart illustrates how EBITDA margin and PAT margin diverged from the flatter revenue growth line beginning in FY2024.
Profitability Ratios
Return metrics were compressed through FY2021–FY2023, with ROE declining from 9.8% to 8.0% and ROCE edging down from 22.0% to 20.2% . FY2024 marked the turning point: ROE reached 15.6% and ROCE 32.0% . By FY2025, ROE stood at 26.9% , ROCE at 39.9% , and ROA at 9.6% — all materially ahead of their FY2021 bases. Sustained margin expansion at the current pace would further compound returns, underpinning the investment case.
| Metric | 2021 | 2022 | 2023 | 2024 | 2025 |
|---|---|---|---|---|---|
| ROA | 2.2% | 2.1% | 2.0% | 3.9% | 9.6% |

Stelmec's customer base spans government utilities, public-sector bodies, and blue-chip private contractors, providing breadth but also exposing the business to the structural constraints of tender-driven procurement.
Customer Base & Relationships
The company serves a diversified mix of state and private power utilities, with named anchor customers including Jaipur Vidyut Vitran Nigam Limited, BSES, and JSW Renewables, alongside major State Electricity Boards and transmission companies . Long-standing relationships with these utilities have enabled Stelmec to entrench itself with prominent private turnkey contractors — Larsen & Toubro, ABB Ltd., Bajaj Electricals Ltd., Jyoti Structures Ltd., Ashoka Buildcon, Sunil Hitech Ltd., SMS Infra, and Lanco Infratech Ltd. — as well as wind turbine manufacturers Suzlon and Enercon . The company is also approved across Water Supply Boards, Municipal Corporations, and Irrigation Departments , broadening its addressable public-sector base. Stelmec customises products and solutions to the specific application requirements of these customers , which deepens stickiness but increases project-level execution risk.
Contract Structure & Payment Risk
Government contracts are awarded through a tender-based system, which keeps margins range-bound in a fragmented and competitive market . The payment cycle reflects this dynamic: receivable days stood at 163 days in FY22 (down from 172 in FY21), while payables ran at 149 days in FY22 . The narrow gap between receivables and payables leaves limited structural buffer, making cash flow sensitive to any delay in government disbursements. No quantified revenue concentration data for the top 5 or 10 customers is available in disclosed sources.
