Lumino Industries Limited

Sector: Power Transmission & Distribution — Manufacturing + EPC (Conductors, Cables & Electrical Wires).

1. Overview

Lumino Industries Limited is a product-driven, integrated engineering, procurement and construction (EPC) player in India's power transmission and distribution (T&D) industry, with a dual focus on in-house manufacturing and project execution. The company designs, engineers, manufactures and distributes conductors, power cables, electrical wires and other specialised products, and also manufactures high-temperature low-sag (HTLS) conductors used in transmission and distribution lines. The business traces its origins to a partnership firm formed in 1989, with the present company incorporated in 2005.

The company operates two complementary business segments — Manufacturing and EPC. Its Manufacturing segment contributed approximately 69.74%, 64.96% and 65.60% of Revenue from Operations in Fiscals 2026, 2025 and 2024 respectively, spanning three product categories: aluminium conductors, power cables and electrical wires (the latter under the 'Lumicon' brand, launched in Fiscal 2023).

Operationally, Lumino runs two manufacturing facilities in Howrah, West Bengal, with a combined capacity of 40,000 MT of aluminium consumption per year, an aggregate area of 264,208 sq. ft., and four supporting warehouses (~156,600 sq. ft.)

2. Business Model and Revenue Streams

Lumino's model is built on vertical integration between its Manufacturing and EPC arms, where in-house products are consumed captively in EPC projects — reducing external dependence, stabilising demand, and improving bidding competitiveness and receivable cycles.

Revenue by segment (₹ Crore)

Segment shares per RHP disclosure (Manufacturing 69.74% / 64.96% / 65.60% of Revenue from Operations); segment rupee amounts approximated from these percentages.

Key operating characteristics

• Customer profile: Business is substantially dependent on state-owned electricity entities, which contributed 53.12%, 79.89% and 85.58% of Revenue from Operations in Fiscals 2026, 2025 and 2024 — a declining but still material concentration.
• Customer concentration: The top 10 customers contributed 46.52%, 80.33% and 90.78% of Revenue from Operations across the same periods, indicating meaningful (though improving) single-customer risk.
• Order book: Aggregate order book stood at ₹3,149.88 Crore as at March 31, 2026 (₹2,436.27 Cr FY25; ₹1,940.57 Cr FY24), split Manufacturing ₹1,157.90 Cr and EPC ₹1,991.98 Cr.
• Bidding intensity: Tender participation grew to ₹11,322.46 Crore in FY26 (₹8,424.92 Cr FY25), reflecting an expanding EPC pipeline.
• Captive in-sourcing: In-sourced share of products used in EPC projects was 23.08%, 53.83% and 65.49% in Fiscals 2026, 2025 and 2024 — the declining trend reflects EPC scaling faster than captive supply.

3. Products and Service Portfolio

Manufacturing segment — three core product categories

• Aluminium conductors: Used in overhead distribution and transmission lines; core to efficiently transmitting electrical energy from generation sources to end consumers. Includes HTLS conductors for capacity enhancement on existing corridors without new infrastructure.
• Power cables: A wide variety used in power distribution substations, industrial applications, communication systems, electrical panels and machine tools.
• Electrical wires (brand 'Lumicon'): Entered in Fiscal 2023; comprises thermoset insulated wire, earth wires and house wires.

EPC segment — services

Turnkey engineering, procurement and construction of power T&D projects across domestic and international geographies, executed for governmental authorities and private-sector players, with in-house products supplied captively.

Geographic reach

Beyond India, Lumino supplies international clients — government-owned electricity companies, public enterprises and electricity boards — in the United States, Mali, Burkina Faso, Côte d'Ivoire, Nepal, Bangladesh, Kenya, Ghana, Rwanda and Ethiopia.

4. Key Business Strengths

• Integrated product-driven EPC model: A growing power-EPC player with in-house manufacturing capabilities that enable captive consumption, competitive bidding and shorter execution timelines.
• Well-developed manufacturing base: Integrated facilities with an extensive, certified product range and 40,000 MT annual capacity supporting quality-controlled captive supply.
• Strong and diversified order book: ₹3,149.88 Crore as at FY26, spanning domestic and international projects across government and private clients.
• International alliances: Strategic partnerships with prominent global companies (including for HTLS conductor technology) that expand the product portfolio and technical capability.
• Superior profitability metrics: Second-highest RoE (24.62%) among its benchmarked listed peers, with a 20.43% revenue CAGR (FY24–FY26).
• Experienced management: A promoter-led team with over three decades of entrepreneurial and managerial experience in power infrastructure.

5. Future Growth Strategy

• Leveraging core competencies in power-T&D EPC: Expanding the order book by capitalising on integrated execution capability and long-standing client and partner relationships.
• Expanding manufacturing capacity and product development: Scaling production and broadening the specialised product range to deepen captive consumption and margins.
• Growing global presence and entering new markets: Extending the international client base across Africa, South Asia and North America.
• Strengthening technology partnerships: Deepening alliances with international companies to enhance the product portfolio (e.g., HTLS conductors for grid modernisation and renewable integration).
• Improving bid-to-win efficiency: Using in-house manufacturing to bid more competitively and convert a larger share of a growing tender pipeline.
