India's power sector is in the middle of a generational transformation. Transmission lines are being upgraded, rural electrification is accelerating, railways are going electric, and solar capacity is being added at record pace. Against this backdrop, Lumino Industries Limited- a Kolkata-based, three-decade-old integrated player in power transmission and distribution, is tapping the public markets with a ₹700 crore IPO.
But is this a compelling infrastructure play, or does the fine print tell a more complicated story? Here's a deep dive.
The IPO opens on August 27 and closes on August 31, 2026, with a total issue size of up to ₹700 crore. This includes a fresh issue of up to ₹500 crore and an offer for sale of up to ₹200 crore. The price band has been set at ₹78 to ₹82 per share.
Lumino Industries is not your typical cables company. Since commencing operations in 1989, it has built what it calls a "product-driven integrated engineering, procurement & construction (EPC) model"; meaning it both manufactures the products (conductors, cables, wires) and executes the infrastructure projects (EPC contracts) that use them.
The manufacturing arm contributes 69.74% of FY26 revenue and produces three core product lines: aluminium conductors (including advanced high temperature low sag variants used for high-capacity power lines), power cables (including railway signalling cables and low voltage aerial bunch cables), and electrical wires sold under its retail brand 'Lumicon', launched in FY23. The EPC arm- contributing the remaining 30.26%, executes turnkey contracts across power transmission and distribution, extra high voltage (EHV) substations, railway electrification, solar power, and even water management projects.
The integration is the company's core pitch. By manufacturing in-house and consuming those products in its own EPC projects, Lumino claims cost efficiencies, tighter supply chain control, and more competitive project bids. The company has completed 55 power distribution projects covering approximately 80,000 circuit kilometres of distribution lines; not just across India, but also internationally in Rwanda, Africa. It exports to countries including the USA, Nepal, Bangladesh, Kenya, Ghana, and Ethiopia.
The macro case for Lumino is genuinely strong. India's conductors market grew from ₹10,200 crore in FY20 to ₹22,700 crore in FY26 at a 14% CAGR, and is projected to reach ₹40,000–46,000 crore by FY31. The broader cables and wires market- already at ₹1,61,800 crore in FY26; is expected to nearly double to ₹2,98,000–3,12,000 crore by FY31.
Government schemes are the primary engine: the PM Surya Ghar Muft Bijli Yojana, the Revamped Distribution Sector Scheme (RDSS), railway electrification mandates, metro rail expansion, and smart city initiatives are all creating sustained demand for exactly what Lumino makes and installs. India's total power sector investment is projected to increase 1.9x–2.2x from ₹19.2 lakh crore (FY22–26) to ₹37–42 lakh crore (FY27–31).
The organised sector is also consolidating its advantage- organised players now hold 76–78% market share, up from 72–74% in FY20, at the expense of smaller unorganised players.
Financially, Lumino has delivered consistent improvement across the key metrics that matter.
| Metric | FY24 | FY25 | FY26 |
|---|---|---|---|
| Revenue from Operations | ₹1,407.3 cr | ₹1,918 cr | ₹2,041 cr |
| EBITDA Margin | 10.31% | 11.62% | 11.71% |
| PAT | ₹86.6 cr | ₹124.6 cr | ₹160 cr |
| PAT Margin | 6.08% | 6.40% | 7.66% |
| Return on Equity (ROE) | 21.52% | 24.52% | 24.62% |
| EPS (Basic) | ₹3.56 | ₹5.11 | ₹6.57 |
Revenue has grown 45% in two years. PAT has nearly doubled. EBITDA margins are expanding steadily, and at 11.71%, they compare favourably against a peer average of ~8.61%. ROE at 24.62% signals efficient use of shareholder capital. The order book; a critical forward indicator for EPC companies, stands at a robust ₹3,149 crore as of March 31, 2026, roughly 1.54x FY26 revenue, providing strong near-term visibility.
On paper, the financial trajectory is impressive. But dig deeper, and some cracks begin to appear.
1. Debtor days are ballooning
The single most important operational concern is the sharp deterioration in working capital. Debtor days have expanded from 92 days in FY24 to 112 days in FY25 to 145 days in FY26. Inventory days have also crept up from 39 to 56. As a result, working capital days have surged from just 11 days in FY24 to 86 days in FY26.
This is partly structural; EPC companies working with government utilities are notorious for delayed payments. But the pace of deterioration is steep. It means the company is effectively financing its government clients, tying up more and more cash in receivables even as revenue grows. If this trend continues, it could pressure cash flows and increase borrowing requirements.
2. A regulatory notice that cannot be ignored
Buried in the risk factors is a disclosure that deserves serious attention. In June 2023, Lumino received a notice from the Registrar of Companies, West Bengal, under Section 206(1) of the Companies Act, 2013- following a complaint alleging non-compliance and corrupt practices in securing government tenders and contracts. The company states it has responded and no subsequent notice has been received.
No further action does not mean closure. For a company whose entire EPC business depends on winning government contracts, this is a reputational and legal overhang that investors cannot simply overlook.
3. Promoter selling
Of the ₹700 crore total IPO size, ₹200 crore is an Offer for Sale (OFS); with MD Devendra Goel selling ₹150 crore worth of shares and Whole-time Director Jay Goel selling ₹50 crore worth.
Promoter exits during an IPO are not inherently wrong; but when the same promoters are asking public investors to fund the company's growth, partial exits at listing raise legitimate questions about conviction. It also means a portion of IPO proceeds flow to promoters, not to the business.
4. The integration advantage is weakening
Lumino's core differentiator is its integrated model; manufacturing products that it then uses in its own EPC projects. Yet the data tells a different story: captive consumption of in-house manufactured products in EPC projects has fallen sharply from 65.49% in FY24 to 53.83% in FY25 to just 23.08% in FY26.
If the integration advantage is the primary reason to own this stock over a pure-play manufacturer or EPC company, this trend is a material concern that management needs to address.
5. Governance and compliance concerns
The compliance record shows 52 non-compliance instances in FY24; related to TDS, TCS, and GST- though this has improved to 11 in FY26. More concerning: one of the joint auditors for FY24 (SDP & Associates) did not hold a valid peer review certificate from ICAI, requiring a re-audit by Singhi & Co. Related party transactions, while declining, were as high as 14.92% of revenue in FY25 across 24 categories including loans, purchases, rent, and director remuneration.
None of these individually are deal-breakers, but together they paint a picture of a company that is still maturing its governance infrastructure.
| Component | Amount |
|---|---|
| Fresh Issue | ₹500 cr |
| Offer for Sale (OFS) | ₹200 cr |
| Total IPO Size | ₹700 cr |
| Employee Reservation | Up to ₹10 cr |
The fresh issue proceeds are earmarked for three purposes: debt repayment, capital expenditure of ₹15.01 crore to expand manufacturing capacity from 40,000 MT to 50,980 MT, and general corporate purposes.
Here's the catch: the proposed capex of ₹15 crore is a fraction of the ₹500 crore being raised. The bulk of proceeds are going toward debt repayment and unspecified corporate purposes; which is less growth-oriented than investors might hope. Adding to this, the company has not yet placed any orders or signed definitive agreements for the proposed capex as of the RHP date.
Lumino Industries sits at the intersection of two powerful themes: India's power infrastructure buildout and the shift toward integrated, end-to-end project execution. The financials are genuinely improving, the order book is healthy, and the sector tailwinds are among the strongest in the Indian economy right now.
But the company is also a closely-held, family-run business making its first foray into public markets. The governance infrastructure, compliance track record, and transparency standards are still catching up to what public market investors expect. The RoC notice, the auditor credential lapse, the declining captive consumption, and the worsening debtor cycle are not individually catastrophic, but together, they demand a higher standard of scrutiny.
The Lumino story is ultimately a bet on whether a capable, operationally strong family business can successfully make the transition to being a well-governed, publicly accountable company, while executing in one of India's most promising infrastructure sectors.
That transition is possible. But it is not yet complete.
