Coal India told the exchanges this morning that it has filed a Draft Red Herring Prospectus (DRHP) with SEBI for the IPO of Mahanadi Coalfields Limited (MCL), its largest wholly-owned subsidiary. Coal India is selling up to 66.18 crore shares (about a 10% stake) — the whole issue is an offer for sale by the parent, so MCL itself raises nothing.

What was announced

• The document: a DRHP for MCL, filed with SEBI on 1 September 2026 and disclosed to BSE under Regulation 30 on 2 September 2026.
• Size and structure: up to 66.18 crore (661.8 million) shares, roughly 10% of MCL, entirely an offer for sale (OFS) by Coal India. There is no fresh issue — MCL is not issuing new shares and will not receive any of the money.
• Bankers: SBI Capital Markets, Axis Capital, BOB Capital Markets, IDBI Capital Markets & Securities and IIFL Capital Services.
• How big MCL is: in FY26 it accounted for 21% of India's total domestic coal production and 28.4% of Coal India's own production. Revenue was ₹30,550 crore (down 2.6% year-on-year) and net profit ₹10,678 crore (down 1.3%).
• Context: Coal India has previously said it could divest up to 25% each in MCL and South Eastern Coalfields (SECL). This 10% is the first tranche.

What this type of filing means

A DRHP is the draft offer document a company files with SEBI before an IPO. "Draft" means it is not final — SEBI reviews it and issues observations, after which a Red Herring Prospectus with the actual price band and dates is filed. So a DRHP is a starting gun, not a listing date. The gap is typically a few months and the deal can be resized, delayed or shelved.

The second thing to read carefully is the split between fresh issue and offer for sale:

• Fresh issue: the company creates new shares and keeps the cash — money goes into the business (capex, debt repayment), and existing holders get diluted.
• Offer for sale: an existing shareholder sells shares it already owns. The company gets nothing; the selling shareholder gets the cash. No new shares are created, so there is no dilution of the company's equity base.

Here it is 100% OFS. MCL's balance sheet is unchanged by the IPO. Coal India's stake in MCL falls from 100% to about 90%, and Coal India — not MCL — pockets the proceeds. This is the standard route for the government's PSU listings, where the point is to unlock value and meet minimum public shareholding norms rather than to fund the subsidiary.

Why it matters / potential impact

• Value discovery on a hidden asset. MCL's ₹10,678 crore FY26 net profit is roughly a third of Coal India's ₹31,071 crore consolidated profit, sitting inside the parent with no separate market price. A listing puts a public valuation on that slice for the first time.
• Cash to the parent, not the subsidiary. Because it is a pure OFS, the proceeds land at Coal India. Coal India is already a heavy dividend payer, so investors will watch whether such proceeds support capex, buybacks or payouts — nothing has been committed.
• No dilution for Coal India shareholders. You are not issued fewer shares or new ones. What changes is that Coal India will own ~90% of MCL instead of 100%, so roughly a tenth of MCL's future profit becomes attributable to outside minority shareholders in the consolidated accounts.
• The holding-company question. Conglomerates that own unlisted subsidiaries often trade at a discount to the sum of their parts. Listing subsidiaries can narrow that gap — or, once the subsidiary is separately listed and visible, investors may simply choose the subsidiary over the parent. Both happen; neither is guaranteed.
• Track record so far. Coal India listed two subsidiaries earlier in 2026: Bharat Coking Coal (BCCL) at an issue price of ₹23, listed 19 January 2026, and CMPDI at ₹172. As of a late-June 2026 review both were trading well above their issue prices. Past IPO reception says nothing about how this one will price.
• What's genuinely uncertain: MCL's revenue and profit both fell in FY26. Coal volumes, e-auction premiums and wage costs drive that line, and a shrinking-profit asset is a harder sell than a growing one.

Is it expensive?

Coal India trades at about ₹402 a share (1 September 2026), a market cap of roughly ₹2,47,341 crore, a P/E of about 7.9 and a price-to-book near 2.1, with a dividend yield around 6.6% and ROCE of ~35% (Screener.in). On headline multiples that is cheap in absolute terms — single-digit earnings multiple, high returns on capital, large payout.

Against a named listed peer: NMDC, the state-owned iron-ore miner, trades at a P/E of about 10.3 on a market cap of roughly ₹76,701 crore, price-to-book ~2.2, dividend yield ~2.9%. So Coal India is the larger business at the lower earnings multiple and the far higher yield.

The honest framing: commodity PSUs with flat-to-falling volumes and a long-run energy-transition question routinely trade at low multiples, and a low P/E on a business whose profit shrank last year is not automatically a bargain — it can be the market pricing in decline. Cheap versus a peer is a starting question, not an answer, and none of this is a target price or a recommendation.

The business

Coal India is a Maharatna PSU under the Ministry of Coal and the world's largest coal producer, supplying the bulk of India's domestic coal. It is a holding company: actual mining happens in regional producing subsidiaries — Mahanadi Coalfields (Odisha), South Eastern Coalfields, Northern Coalfields, Bharat Coking Coal, Western/Central/Eastern Coalfields and others — plus CMPDI for mine planning and consultancy. It also runs coal washeries. Its customers are mainly power generators, with steel, cement, fertiliser and brick makers taking the rest.

The practical point for reading this filing: MCL is one subsidiary, not the whole company. It is a large one — 28.4% of group production and about a third of group profit — but Coal India's other subsidiaries and its overall volume and pricing trend still drive the parent's earnings far more than this IPO does.

Beginner takeaway

A DRHP is a draft, not a launch — it means the paperwork has started, and SEBI still has to clear it. Because this one is a pure offer for sale, no new money enters Mahanadi Coalfields; Coal India simply sells a tenth of something it already owns. Read the fresh-issue-versus-OFS split first in any IPO announcement, because it tells you immediately whether the company or its owner is the one getting the cash.

FAQ

Do I get MCL shares automatically because I own Coal India? No. This is a normal IPO where Coal India sells shares to the public — it is not a demerger or a bonus. Whether a reserved quota for Coal India shareholders exists would be specified in the final offer document.

What is the difference between a DRHP and an RHP? The DRHP is the draft filed with SEBI for review and has no price band or dates. The RHP comes later, after SEBI's observations, and carries the price band and the issue schedule.

Does Coal India lose control of Mahanadi Coalfields? No. Selling about 10% takes its stake from 100% to roughly 90%, so MCL stays a subsidiary and remains consolidated in Coal India's accounts. Coal India has said it may go up to 25% over time.

Why would the parent sell a profitable subsidiary's shares at all? Two usual reasons: to raise money at the parent level, and to establish a public market price for an asset that was previously invisible inside a conglomerate. Government-owned groups also list subsidiaries as part of disinvestment policy.
