Mahanadi Coalfields IPO Gets SEBI Nod: Can It Justify an Estimated ₹90,000 Crore Valuation?

Mahanadi Coalfields has a business many new IPO companies would envy: it produced over 218 million tonnes of coal in FY26 and earned nearly ₹10,700 crore in net profit. Yet its revenue and profit have both fallen over the last two financial years. Now, the Coal India subsidiary is preparing to enter the stock market with a possible valuation approaching ₹90,000 crore.

According to a Bloomberg report published on November 3, 2026, citing people familiar with the matter, the IPO could raise up to $1 billion and value Mahanadi Coalfields at up to $10 billion. That is approximately ₹90,000 crore at an illustrative exchange rate of ₹90 per dollar. These are reported estimates, not an IPO price or valuation confirmed by Coal India or SEBI.

According to Moneycontrol's November 4 report and Reuters' November 5 report, SEBI issued its final observations on the company's draft IPO papers on November 4, moving the proposed listing a step closer. For investors, the bigger question is whether Mahanadi's enormous scale, cash generation and coal reserves are enough to support that reported valuation despite weakening profits.

What Has SEBI Approved, and How Big Could the Mahanadi Coalfields IPO Be?

Coal India plans to sell up to 66.18 crore existing drhp Mahanadi Coalfields shares, equivalent to 10% of the subsidiary. This is an offer for sale (OFS), not a fresh issue: investors will buy existing shares from Coal India, and Mahanadi Coalfields will not receive the IPO proceeds for expansion or debt repayment.

The distinction between IPO size and valuation matters. If Coal India sells 10% for ₹9,000 crore, investors are effectively valuing the whole company at ₹90,000 crore. It does not mean Mahanadi is raising ₹90,000 crore. The rupee amounts are illustrative conversions of Bloomberg's dollar estimates; the actual issue size will depend on the final price band and shares sold.

Bloomberg reported that the offering could launch in the second half of November or early December 2026, but that timetable is also tentative. Regulatory clearance is not the same as an announcement of IPO opening dates.

What Does Mahanadi Coalfields Actually Do, and Why Is It So Important?

Mahanadi Coalfields, set up in 1992, mines mainly non-coking coal in Odisha's Talcher and Ib Valley coalfields. Non-coking coal is primarily used to generate electricity, rather than to make steel directly. Its customers include power stations, captive power plants and industries such as cement and sponge iron.

As of June 30, 2026, the company operated 17 mines: 14 open-cast and three underground. Open-cast mining, which involves removing the soil and rock above coal seams, supplies virtually all its output. In FY26, MCL produced 218.31 million tonnes, making it Coal India's largest coal-producing subsidiary and contributing around 28.4% of its parent's production.

A second strength is how long the coal resource could last. The DRHP cites 9,840.31 million tonnes of audited coal reserves, enough for roughly 45 years of production at the FY26 rate. But this is an estimate based on existing reserves and production levels, not a guarantee that every tonne can be mined profitably or without environmental approvals and other constraints.

Mahanadi also has an established market for much of its production. In FY26, thermal power customers accounted for 68.62% of product sales, while approximately 82.12% of product-sale revenue came through long-term fuel supply agreements. These contracts help make demand more predictable, but they also mean the company cannot freely charge whatever price it wants for most of its coal.

Why Have Mahanadi Coalfields' Revenue and Profits Been Falling?

The surprising part of the story is that MCL did not suddenly become a small or loss-making miner. It remained exceptionally profitable, but making more coal available has not translated into higher revenue or earnings.

Revenue declined about 2.6% in FY26, while net profit slipped about 1.2%. Compared with FY24, revenue was down 3.4% and profit about 9.7%. Production also fell 3.0% from FY25's 225.17 million tonnes, although it remained above FY24 levels.

Coal pricing helps explain why the financial trend and production trend can look different. MCL sells much of its coal at Coal India's notified prices through fuel supply agreements, while some is sold through auctions and other arrangements. The share of product-sale revenue from fuel supply agreements increased from 77.46% in FY24 to 82.12% in FY26. That makes the mix of contract prices, auction premiums and coal grades particularly important to realised revenue.

Costs matter too. Expenditure on mining and other contract work increased from approximately ₹5,862 crore in FY24 to ₹6,824 crore in FY26, while depreciation also rose. Even when tonnage holds up, a less favourable price mix or higher costs can reduce operating profitability.

The latest quarter in the draft prospectus shows that the picture is not entirely one-way. In the June 2026 quarter (Q1 FY27), revenue grew about 6.4% year on year to ₹8,033.77 crore, although net profit still fell around 2.0% to ₹2,398.78 crore. Investors therefore need to follow both sales recovery and the margin earned on those sales.

Is Mahanadi Coalfields Financially Strong Despite Its Lower Profits?

Yes, the balance sheet has some notable strengths. MCL had borrowings of approximately ₹3 crore at March 31, 2026, and generated around ₹12,478 crore in operating cash flow during FY26, more than its reported net profit of ₹10,698 crore. This indicates substantial cash generation, but the FY26 operating cash-flow figure also benefited from net income-tax refunds of approximately ₹401 crore, unlike the net cash tax paid in FY25. It should not automatically be treated as a recurring annual level.

But profit quality still deserves attention. Other income almost doubled, from approximately ₹1,676 crore in FY25 to ₹3,350 crore in FY26. That helped reported profit while revenue from mining operations declined. Investors should examine the final prospectus for the sources and repeatability of this income rather than assuming every rupee of profit comes from selling coal.

There is also a cash-collection warning. Trade receivables, which are amounts customers owe the company, rose from approximately ₹2,160 crore at March 2024 to ₹3,744 crore at March 2026 and ₹4,220 crore at June 2026. Strong customers and long-term contracts are useful only if the money is collected on time.

The balance sheet also contains significant provisions and legal exposures associated with a capital-intensive mining business. So, although MCL has very little borrowing, low debt does not mean the company has no financial or regulatory obligations.

Can a Reported ₹90,000 Crore Valuation Be Justified?

At the reported valuation, MCL's FY26 earnings would imply a price-to-earnings (P/E) ratio of about 8.4 times. In plain language, a buyer would be paying about ₹8.40 for every ₹1 the company earned in FY26. That looks different from the high multiples sometimes seen in fast-growing IPOs, but a low-looking P/E is not automatically a bargain when profits are under pressure.

Calculations using MCL's FY26 consolidated net profit of ₹10,698.12 crore and 661.8363 crore outstanding shares from the DRHP. These are hypothetical valuation scenarios, not an announced IPO price band or a valuation forecast.

MCL may deserve credit for its scale, large reserves, low borrowing and cash generation. On the other hand, its exposure to one fuel, regulated pricing, mining obligations and weakening earnings could limit the multiple investors are prepared to pay. The final price matters much more than the Bloomberg estimate when assessing whether the valuation offers sufficient room for these risks.

What Are the Biggest Risks Investors Should Understand?

• Coal prices and customer concentration: Most of MCL's sales depend on thermal power demand, and its ten largest customers contributed approximately 55.94% of FY26 revenue. Changes in notified prices, auction premiums or demand from major utilities can affect profits even if the company keeps producing large quantities of coal.
• Payments and contractor dependence: MCL depends on contractors for mining-related work, and its top ten contractors accounted for approximately 60.02% of FY26 contractual expenses. Delays in work, transportation bottlenecks or payments from major customers can affect output and cash flow.
• A significant unresolved mineral-levy issue: The DRHP reproduces a Comptroller and Auditor General observation concerning the Supreme Court's rulings on state mineral levies. It cites Coal India's legal department's estimate of approximately ₹31,227.80 crore in potential exposure associated with state mineral levies for MCL. The audit comment raises a disagreement over whether and how that exposure should be recognised or disclosed. This is not a confirmed demand payable today, and the amount must not be added mechanically to reported borrowings. Investors need the company's updated response in the final offer document. Separately, the CAG comment questions disclosure of an approximately ₹35,194.79 crore contractual commitment concerning the Siarmal opencast mine project. A future contract commitment is not the same as an immediate debt obligation.
• Environmental and long-term demand risks: Mining requires land, permits, transport infrastructure and spending on restoration. While coal remains central to India's electricity production, greater use of renewable energy, environmental restrictions and changes in power-sector policy could affect how much coal is required and how profitably it can be sold over time.
• Control and minority-shareholder interests: Even after a full 10% offer, Coal India would own around 90%. Public investors would hold a minority stake, while key decisions on investment, dividends and governance would continue to be influenced by the parent and the government.

What Does the IPO Mean for Existing Coal India Shareholders?

The IPO could help Coal India turn a small part of its ownership in MCL into cash while keeping control of the subsidiary. At the illustrative ₹90,000 crore valuation, selling 10% would bring in about ₹9,000 crore before expenses. Coal India could then decide how to use that money, subject to its own business priorities and governance processes.

But this is not a new profit stream from mining. MCL's revenue and profit are already included in Coal India's consolidated accounts. A separate listing may make MCL's market value more visible, but investors should not simply add the entire ₹90,000 crore to Coal India's valuation as if it were a newly acquired business.

There is a possible dividend angle too. The DRHP records approximately ₹7,650 crore of dividends paid to Coal India in FY26. Future dividends from MCL would be shared among its shareholders in proportion to their holdings, but the historical amount does not guarantee the same payout after listing.

The draft offer documents also provide for a proposed reservation for eligible Coal India shareholders. However, the eventual size of that portion, the eligibility cut-off and other application terms must be checked in the final red herring prospectus. Owning Coal India shares does not automatically give investors free MCL shares or guarantee IPO allotment.

When Will the Mahanadi Coalfields IPO Open, and What Should Retail Investors Check?

As of November 5, the official price band, lot size, opening and closing dates and listing date had not been announced. Bloomberg's late-November or early-December timing is an indication of what may be under consideration, not a confirmed timetable.

Once the red herring prospectus is released, retail investors should look first at the price band, minimum application amount, revised financial disclosures and final risk factors. The draft broadly provides for at least 35% of the net offer for retail investors, but applying does not guarantee allotment, and any proposed shareholder or employee reservations are governed by their final terms.

Investors can follow upcoming IPOs on INDmoney and read its IPO application guide to understand the application, UPI mandate and allotment process. The decision to participate, however, should follow a review of the final valuation rather than the size of the IPO alone.

Author's Take: What Will Decide Whether the Mahanadi Coalfields IPO Valuation Makes Sense?

Mahanadi Coalfields is not asking investors to believe that profits might arrive someday. It already earns over ₹10,000 crore a year, produces more coal than any other Coal India subsidiary and generates substantial operating cash. That gives the proposed listing a real financial foundation.

But the reported ₹90,000 crore valuation should not end the analysis; it should start it. Revenue has declined for two years, production fell in FY26, and other income has become more important to overall profitability. Customer collections, potential state-levy exposure and the economics of future coal demand also need to be considered.

The most useful next step is to compare the final IPO price with earnings that can be sustained from coal operations, rather than just total reported profit, and examine whether the price leaves a margin for slower growth or higher costs. If operating margins and cash collections improve, an approximately 8.4x earnings valuation could look more supportable. If they weaken or material liabilities emerge, even a single-digit P/E can prove demanding.

The investment question is not whether Mahanadi Coalfields is a big business. It clearly is. It is how much investors should pay for its future earnings, given the risks behind them.
