Lumino Industries opens on August 27 with a grey market premium of +₹50 (+61%) on an issue price of ₹82 — and unlike most of the headline numbers flying around this cycle, this one has barely moved in five days.

What Lumino Industries actually does
Lumino Industries is a Kolkata-headquartered company with manufacturing at Howrah and more than three decades in India's power and energy sector. It is not a single-line business — it runs two connected segments, and understanding the split matters for how you read the numbers.
Manufacturing
The manufacturing arm makes aluminium conductors, power cables and electrical wires. The product list includes HTLS, ACSS and ACFR conductors, LV aerial bunch cables, railway signalling cables, thermoset insulated wires, earth wires and house wires.
The HTLS piece is the one worth noting. High-temperature low-sag conductors let an existing transmission line carry substantially more current without rebuilding the towers. As India pushes to move more power through infrastructure it already owns, reconductoring with HTLS becomes a structural demand driver rather than a one-off project cycle.
EPC
The engineering, procurement and construction arm delivers projects across power distribution and transmission, railway electrification, HTLS reconductoring, solar power, and extra-high-voltage substations.
Running both segments means Lumino can manufacture the conductor and then install it under its own EPC contract. That vertical integration is the core of the investment case: margin captured at two points in the same project rather than one.
The financials
Based on publicly reported figures, the growth trajectory is consistent rather than spectacular — which, for an infrastructure contractor, is arguably the better outcome.
- Revenue from operations: ₹1,407 crore (FY24) → ₹1,918 crore (FY25) → ₹2,041 crore (FY26)
- Profit after tax: ₹86.6 crore (FY24) → ₹124.6 crore (FY25) → ₹160 crore (FY26)
- Return on equity: roughly 24.5% across FY25–FY26
- Return on capital employed: approximately 25.75%
- Debt-to-equity: improved to 0.53
Two things stand out. Profit has grown considerably faster than revenue — PAT up around 85% over two years against revenue up roughly 45% — which points to margin expansion rather than volume alone. And a debt-to-equity ratio of 0.53 is comfortable for an EPC business, where stretched balance sheets are the usual failure mode.
Revenue growth did slow markedly in FY26, from a 36% jump in FY25 to about 6%. Profit still grew 28% in the same period, so the margin story held, but a single-digit topline year is worth registering rather than glossing over.
The order book is the number to watch
As of March 31, 2026, the order book stood at ₹3,149.88 crore — ₹1,991.98 crore of EPC orders and ₹1,157.90 crore of manufacturing orders.
Set against FY26 revenue of ₹2,041 crore, that is roughly 1.5 times annual revenue already contracted. For an EPC business, forward visibility of that scale is a genuine strength, because the central risk in the model is not demand — it is execution and working capital.
GMP analysis — why the stability matters more than the number
Here is the full grey market history from our tracking:
- August 21: +₹45 (+55%)
- August 22: +₹51 (+62%)
- August 23: +₹50 (+61%)
- August 24: +₹49 (+60%)
- August 25: +₹50 (+61%)
Across five sessions the premium has held between ₹45 and ₹51 — a range of six rupees. It has not spiked, it has not faded, and it has not swung on a single day's sentiment.
We also track how many independent grey market sources contribute to each reading, and Lumino's is a two-source consensus figure rather than a single quote. That combination — a stable premium confirmed across multiple desks — is a meaningfully different signal from a headline number that jumped overnight on one operator's quote.
For context within the same week: Kwick Forensic Solutions, which opens on the same day, carries a higher headline GMP at +68% — but that reading currently comes from a single source. A higher number is not automatically a stronger signal. Where the premium comes from, and how long it has held, matter just as much.
We publish the source count alongside every GMP reading we track, which you can see on our GMP performance tracker.
What our listing data says about a GMP like this
We track every IPO through to its actual Day 1 listing price. Across the 81 listings where we now have confirmed outcomes, the record breaks down like this:
- 59 of 81 listed at a premium — a 73% positive rate overall
- Average listing gain +19.1%, but the median only +10.1%
- Mainboard specifically: 83% positive across 29 listings, averaging +17.4%
- Where GMP read 50% or higher, all 8 such IPOs listed positive, averaging +67.3% actual against +72.9% predicted
Lumino sits in that last bucket at +61%. On our data, a GMP above 50% has been directionally reliable without exception so far — but the same data shows the magnitude tends to run slightly ahead of reality. GMP has been an excellent guide to whether a listing will be positive and a poor guide to by how much.
The gap between the +19.1% average and the +10.1% median is the other number worth carrying into any application. A handful of exceptional outcomes pull the average up; half of everything we have tracked returned under 10.1%.
Strengths
- Vertically integrated — manufactures conductors and installs them under its own EPC contracts, capturing margin twice
- Order book of ₹3,149.88 crore against FY26 revenue of ₹2,041 crore, giving roughly 1.5x forward revenue visibility
- Profit growing faster than revenue, indicating margin expansion rather than volume-driven growth alone
- Debt-to-equity at 0.53 — conservative for an EPC contractor
- HTLS conductors and railway electrification are structural demand themes, not cyclical project spikes
- Return on equity around 24.5% and ROCE near 25.75%, both healthy for the sector
Risks
- Revenue growth slowed sharply in FY26 to roughly 6%, down from 36% the previous year
- EPC revenue is lumpy by nature — project timing can move earnings between quarters and distort trends
- Order book concentration and client mix are not visible from summary figures; the RHP is the place to check who the counterparties are
- Working capital intensity is the standard pressure point in EPC, and receivable cycles deserve scrutiny
- A meaningful portion of the issue is an offer for sale, meaning part of the proceeds goes to existing shareholders rather than into the business
- Aluminium and copper input costs are volatile and feed directly into manufacturing margins
- Public sources currently disagree on the final issue size — confirm it in the RHP before applying
Verdict — apply or avoid?
Lumino is the more conventional of the two IPOs opening on August 27, and that is meant as a compliment. It is a thirty-year-old business with real manufacturing assets, a contracted order book worth about 1.5 times last year's revenue, healthy return ratios and a conservative balance sheet, arriving into a power transmission and railway electrification cycle that has structural rather than speculative demand behind it.
The grey market has priced it at +61% for five consecutive sessions across two independent sources. On our own tracking, that combination of stability and multi-source confirmation has historically been a firmer indicator than a larger number with thinner sourcing.
Our view: reasonable for listing gains, with the usual caveat that a +61% GMP has historically translated into a somewhat smaller actual gain rather than a larger one. For a longer hold, the order book and margin trajectory make a credible case — but check the FY26 revenue slowdown and the working capital position in the RHP before treating this as a multi-year position rather than a listing-day trade.
Subscription data will tell you more than GMP once the issue opens. Watch the qualified institutional buyer portion in particular, since institutional appetite for an infrastructure contractor is a more informative signal than retail enthusiasm.

What does Lumino Industries do?
It is an integrated engineering, procurement and construction company in the power sector, headquartered in Kolkata with manufacturing at Howrah. It manufactures aluminium conductors, power cables and electrical wires — including HTLS, ACSS and ACFR conductors and railway signalling cables — and separately executes EPC projects across transmission and distribution, railway electrification, solar and EHV substations.
Is Lumino Industries IPO good for listing gains?
The signals are constructive: a +61% GMP that has been stable for five sessions with two-source confirmation, an order book at roughly 1.5 times annual revenue, and return ratios near 25%. On our tracking of 81 listings, every IPO with a GMP above 50% has so far listed positive. That said, GMP consistently predicts direction better than magnitude, and half of all IPOs we have tracked returned under 10.1%. Review the RHP and apply according to your own risk tolerance.
Lumino Industries or Kwick Forensic — which is the better bet?
They open and close on the same dates. Kwick carries the higher headline GMP at +68% against Lumino's +61%, but Kwick's reading is currently single-sourced while Lumino's is a two-source consensus that has held steady for five days. Lumino is also the larger, older and more established business with a disclosed order book. Higher GMP does not automatically mean the stronger signal.
