Madhur Iron & Steel IPO: The Power Transmission Proxy

The steel company that doesn't make steel

In today's edition, we look at Madhur Iron & Steel (India) Ltd — a Bhilai-based re-roller sitting right in the path of India's power transmission capex cycle, and why its growth story is really a balance sheet story.

If you drove past Plot 21A in the Light Industrial Area of Bhilai, Chhattisgarh, you'd probably not think twice about it. A rolling mill. Some sheds. Trucks going in and out.

But here's the thing about the transmission towers going up across India right now — the ones carrying power from a solar park in Rajasthan to a data centre in Hyderabad. Somebody has to make the steel angles they're bolted together from. And that somebody is usually a company exactly like this one.

Madhur Iron & Steel filed its draft red herring prospectus with SEBI on 6 February 2026. In the unlisted market it's being talked about at around ₹350 crores. So it's worth understanding what you're actually buying.

Let's start with what it is not.

This confuses people, so let's get it out of the way.

Madhur doesn't run a blast furnace. It doesn't melt iron ore. It doesn't make steel.

What it does is buy semi-finished steel — billets and blooms, the chunky intermediate stuff that primary producers churn out — heat it up, and roll it into shapes. Angles. Flats. Channels. Hot-rolled structural sections and some cold-rolled products.

That's the re-rolling business. And it tells you three things immediately.

One, raw material is the business. In FY26, materials consumed and traded stock purchases together ate up roughly ₹393 crores of a ₹444 crore topline. Gross margins land somewhere around 18%. You're not selling a brand. You're selling conversion.

Two, you're a price-taker on both ends. Billet prices move, and your selling price has to move with them. Miss the timing and your inventory becomes the problem.

Three, roughly a third of the revenue isn't manufactured at all. Of FY26's ₹444 crores, ₹152 crores came from simply trading steel — buying and reselling. Volume that flatters the topline but carries thinner margins than the mill does.

Okay. Now the interesting part.

This isn't a story someone made up in a pitch deck. Look at the customers.

Kalpataru Projects International — one of India's largest transmission EPC players, with a tower plant in Raipur, an hour from Bhilai — closed FY26 with an all-time high order book of ₹65,457 crores. Its T&D order book alone was ₹28,572 crores, with 2.5 years of revenue visibility. Management said the domestic transmission bidding pipeline is north of ₹1 lakh crore, with HVDC packages worth ₹30,000–35,000 crores expected to hit the market.

That's one company. There are several. And every one of them needs angles.

India is in the middle of a genuine multi-year grid buildout — renewables need evacuation infrastructure, the Northeast needs expansion, thermal is coming back, data centres need power. Transmission towers are one of the few steel end-uses where you can see the demand five years out.

The railway electrification leg is the second pillar of the story, and Madhur already sells into it. Though a small caution here: the same EPC players who are bullish on transmission are conspicuously lukewarm on railways. Kalpataru's railway business grew 9% last year and management openly said it's staying "cautious and selective." So of the two drivers, transmission is doing the heavy lifting.

Fine. The demand exists. But then the obvious question — why not just buy the EPC company?

Because the EPC names are already crowded, already priced, and already followed by every brokerage in Mumbai.

If you want exposure to the grid buildout, there are broadly three places to stand. The utility ordering it. The EPC contractor building it. Or the guy supplying steel to the contractor. The third one is where Madhur sits — smaller, less watched, and levered to the same tonnage.

And picks-and-shovels only works if the shovel-maker can't be swapped out casually. Two things suggest Madhur isn't easy to swap.

First, the location. Madhur's mill is in Bhilai. So is SAIL's Bhilai Steel Plant — one of the largest integrated steel plants in the country, and a major producer of exactly the semi-finished material a re-roller needs. This isn't inference, either: the company's own banking arrangements include a dealer finance facility from PNB structured around advance remittances to SAIL.

Being next door to your primary supplier matters more than it sounds. Steel is heavy and freight is a real percentage of landed cost. Shorter haulage means cheaper input. It also means shorter lead times, which lets you hold less inventory per rupee of sales — and given that inventory is this company's biggest problem, every day counts. Chhattisgarh's re-rolling cluster exists for exactly this reason.

Then there's the customer side — the one people underrate.

Second, vendor approval is slow. You don't wake up one morning and start supplying Power Grid, Kalpataru or Sterlite Power. Utility and EPC supply chains run on approved vendor lists. Getting on one means test certificates, sample lots, plant audits, trial orders, and a track record of delivering to spec and on time. It routinely takes years, and it happens before you've earned a rupee.

Which is why these relationships, once formed, don't churn. Kalpataru told analysts that over 50% — possibly 60% — of its order book comes from its top 10 clients, with several relationships running 20 years and one at 25. That stickiness runs down the chain too. An EPC contractor midway through a ₹28,000 crore order book with a three-year delivery clock is not shopping around for a new angle supplier to save 2%.

So the moat here isn't technology. It's paperwork, proximity and time. Boring, but real.

Now — is Madhur actually capturing the demand?

Revenue up 31%. Profit up 32%. Return on equity above 22%. For a commodity conversion business, that's a good year.

And they're not sitting on it. Capital work-in-progress jumped from ₹8 lakhs to ₹20 crores during FY26 — a capacity expansion under construction. They've taken on new leasehold land. They've borrowed from RBL Bank to put up a captive solar plant, because rolling mills drink electricity and the cheapest way to protect margins is to stop buying power at grid rates.

Total capex in FY26: ₹27 crores. Against a company earning ₹24 crores.

So what's the catch?

Here's the number that reframes everything.

Cash flow from operations in FY26: minus ₹5.6 crores.

FY25 was worse. Minus ₹40.6 crores.

Two years. ₹42 crores of accounting profit. And ₹46 crores of cash out the door from operations.

This isn't fraud and it isn't unusual. It's just what happens when a working-capital-heavy business grows 30% a year. Every extra rupee of sales needs inventory sitting in the yard and a customer who'll pay in two months.

Look where the money is parked:

• Inventory: ₹173 crores. That's about 150 days of cost of goods. Five months of steel, sitting there.

• Receivables: ₹80 crores, nearly double last year's ₹42 crores. The company's own disclosure says this is partly timing and partly a longer credit period given to customers.

• Payables: ₹69 crores. Suppliers fund some of it, but nowhere near all.

Net it out and roughly ₹200 crores of working capital is supporting a ₹444 crore business. Cash in the bank at year end? ₹22 lakhs. Not crores. Lakhs.

So if the business isn't funding itself, who is?

Lenders. Borrowings have gone from ₹54 crores in April 2024 to ₹136 crores in March 2026. Against ₹118 crores of equity — a debt-to-equity of 1.15x. ICICI, PNB, RBL, Bajaj Finserv, Tata Capital, all secured against inventory, book debts, and the personal guarantees of the promoters.

And that debt costs real money. Finance costs in FY26 were ₹18.5 crores — against a pre-tax profit of ₹32 crores. Interest is eating more than a third of everything the business earns before paying for money. Of that, ₹7.8 crores was letter-of-credit and commission charges — the price of buying billets on credit.

This is the whole story in one line: Madhur's growth isn't constrained by demand. It's constrained by how much working capital it can finance.

Which is precisely why there's a DRHP.

Customer concentration. One customer accounted for ₹97 crores — nearly 22% of FY26 revenue. This is the flip side of the approved-vendor moat: the same qualification barrier that keeps competitors out also means your revenue rests on a handful of names. It's a moat and a single point of failure at the same time.

Related parties. Group entities bought ₹34 crores of steel and were paid ₹5.2 crores in job charges, while ₹10.6 crores of capital goods were purchased from another. The auditor notes these are at arm's length. It's disclosed, it's not enormous relative to a ₹444 crore topline — but it's the kind of thing to read carefully in the DRHP.

Margin risk from above. EPC contractors like Kalpataru run roughly half their order books on fixed-price contracts and hedge aluminium and zinc. Steel, they mostly budget for. When steel prices spike — as they did in Feb–March 2026 — the pressure travels down the chain to suppliers. Re-rollers are the ones with the least pricing power in that chain.

On FY26 numbers, that works out to roughly:

• ~15x earnings

• ~3x book value

• ~9x EV/EBITDA (once you add the ₹136 crores of net debt)

For a business compounding 30% with a 22% ROE, 15x doesn't look expensive. For a commodity re-roller with negative operating cash flow, one-fifth of revenue from a single customer, and interest eating a third of pre-tax profit — it isn't obviously cheap either.

The honest framing is this. You aren't betting on whether India builds transmission lines — that's happening, and Madhur is a legitimate proxy for it, sitting next to its raw material and inside supply chains that take years to enter.

You're betting on something narrower: whether it can convert that demand into cash rather than into ever-larger piles of inventory and receivables funded by ever-larger loans. A good position in a good industry still has to clear that test.

An IPO fixes that once. It doesn't fix it forever.

That's the story. Watch the cash flow statement, not the P&L.

Until next time…
