Mahanadi Coalfields IPO: Coal India’s proposed listing of Mahanadi Coalfields Limited (MCL) could become one of India’s major IPOs of 2026. The public issue involves a sale of up to 10% of the coal producer by its parent company, with the draft prospectus also proposing a reservation for eligible Coal India shareholders.
But beyond the IPO size, Mahanadi Coalfields’ financial statements reveal an interesting contrast. The company reported ₹10,698 crore in FY26 net profit, even as its operating EBITDA declined and margins narrowed.
Its draft red herring prospectus (DRHP) also contains an important disclosure concerning an unresolved potential mineral-levy exposure estimated at ₹31,227.80 crore by Coal India’s legal department.
With regulatory clearance received but the price band and bidding dates still awaited, here is what prospective investors should understand.

1. Coal India to Sell 10% Stake: Who Gets the IPO Proceeds?
The proposed IPO will consist entirely of existing equity shares sold by Coal India.
Unlike a fresh issue, an offer for sale (OFS) does not raise new capital for the company whose shares are being listed.
This means Coal India will receive the proceeds from the stake sale, after applicable expenses and taxes, while Mahanadi Coalfields will not receive fresh funds through the IPO.
If the entire proposed 10% stake is sold, Coal India’s ownership in MCL would decline from 100% to approximately 90%.
An important distinction concerns the overall divestment approval.
In March 2026, Coal India’s board granted in-principle approval to divest up to 25% of its holding in MCL in one or more tranches through an IPO or other permitted market routes.
However, the current DRHP proposes an OFS of only up to 10%.
The two figures are not contradictory: 25% represents the earlier broader approval, while 10% is the size of the present proposed IPO.
2. Will Coal India Shareholders Get a Reservation in Mahanadi Coalfields IPO?
One of the most relevant details for retail investors is the proposed shareholder reservation in the draft prospectus.
The DRHP provides for a Shareholder Reservation Portion for eligible public equity shareholders of Coal India.
Under the draft eligibility provisions, qualifying applicants include individuals and Hindu Undivided Families (HUFs) holding eligible Coal India shares as of the date specified in the Red Herring Prospectus (RHP), subject to applicable conditions.
The draft also describes how eligible shareholders may bid under the reserved category and, subject to restrictions, other investor categories.
However, the final reservation size, applicable dates and offer terms have not been announced.
Does owning Coal India shares guarantee IPO allotment?
No. Holding qualifying shares may provide eligibility to apply under the proposed reservation, but it does not guarantee allotment.
Investors should check the final RHP for the eligibility date, application requirements and reservation details. Purchasing Coal India shares solely in anticipation of an allotment benefit involves market risk.
3. Mahanadi Coalfields Financials: Profit Remains High, But Margins Are Declining
Mahanadi Coalfields is a highly profitable coal producer, but its latest financial statements reveal pressure on underlying operations.
According to its DRHP, revenue from operations declined 2.56% year-on-year to ₹30,549.59 crore in FY26.
Profit after tax also fell 1.17% to ₹10,698.12 crore.
Mahanadi Coalfields Financial Performance
All financial values in ₹ crore unless otherwise stated.
| Financial Metric | FY24 | FY25 | FY26 |
|---|---|---|---|
| Revenue | 31,634.35 | 31,353.02 | 30,549.59 |
| Net Profit | 11,841.55 | 10,825.12 | 10,698.12 |
| Operating EBITDA | 14,680.92 | 13,655.48 | 12,735.24 |
| Operating EBITDA Margin | 46.41% | 43.55% | 41.69% |
| Operating Cash Flow | 6,325.58 | 7,704.96 | 12,477.53 |
| Coal Production (MT) | 206.10 | 225.17 | 218.31 |
The Important Difference Between EBITDA and Operating EBITDA
The company’s total EBITDA increased approximately 4.9% to ₹16,084.93 crore in FY26 from ₹15,331.11 crore in FY25.
However, operating EBITDA declined approximately 6.74%, from ₹13,655.48 crore to ₹12,735.24 crore.
Operating EBITDA excludes other income under the company’s stated calculation methodology.
Its operating EBITDA margin also declined from 43.55% to 41.69%.
This matters because the improvement in total EBITDA did not translate into stronger underlying operating profitability.
At the same time, cash flow from operations improved significantly in FY26, showing that the business continues to generate substantial cash.
What investors should watch: Whether MCL can sustain cash generation while improving production, operating margins and earnings growth.
4. June 2026 Quarter: Coal Production Falls, But Dispatch Increases
The company’s June-quarter operating performance reveals another important contrast.
Mahanadi Coalfields reported revenue of ₹8,033.77 crore for the quarter ended June 30, 2026, up approximately 6.4% year-on-year.
However, net profit declined approximately 2% to ₹2,398.78 crore.
The operational figures show an interesting divergence:
| Operational Metric | Q1 FY26 | Q1 FY27 | Change |
|---|---|---|---|
| Coal Production | 51.58 MT | 42.53 MT | -17.55% |
| Coal Offtake | 51.98 MT | 54.97 MT | +5.75% |
| Coal Dispatch | 51.74 MT | 54.80 MT | +5.91% |
While production declined sharply, coal offtake and dispatch increased.
The higher dispatch indicates that coal movement to customers remained strong during the quarter, despite lower production.
However, production and dispatch follow different operating cycles. Investors should examine inventory movements and subsequent production recovery before drawing conclusions about sustained demand or future profitability.
5. How Big Is Mahanadi Coalfields?
Mahanadi Coalfields is one of India’s largest coal producers and an important subsidiary of Coal India.
Its operations are concentrated in Odisha’s Talcher and Ib Valley coalfields.
According to the CRISIL report cited in the DRHP, MCL produced 218.31 million tonnes of coal in FY26, accounting for approximately 22.4% of India’s non-coking coal production.
It contributed around 28.3% of Coal India’s total coal production during the same financial year.
As of June 30, 2026, MCL operated 17 mines, comprising 14 opencast and three underground mines.
The company’s major customers include thermal power plants, independent power producers and industrial consumers.
This large operating scale provides an established production base, although future growth remains dependent on coal demand, mining productivity and regulatory conditions.
6. The ₹31,227.80 Crore Potential Mineral-Levy Exposure
One of the most significant disclosures in Mahanadi Coalfields’ DRHP concerns a potential liability arising from state levies on mineral-bearing land.
The company’s prospectus reproduces observations from the Comptroller and Auditor General of India (CAG) supplementary audit.
The matter relates to the legal implications of the Supreme Court’s decisions concerning states’ powers to impose certain mining-related levies.
MCL stated that the consequential financial impact, if any, was not ascertainable, while related litigation concerning Odisha’s earlier legislation remained pending.
However, the CAG observation notes that Coal India’s legal department had estimated potential liability relating to MCL at ₹31,227.80 crore.
This distinction is critical.
The amount is an estimate referenced in an audit-related disclosure. It is not an established demand requiring immediate payment, and the eventual financial impact remains uncertain.
The CAG also raised concerns regarding the company’s disclosure of the potential contingent liability.
For investors, the relevance lies in the scale of the unresolved exposure and the possibility of future legal, regulatory or accounting developments.
Any subsequent clarification in the final offer documents could materially affect how investors evaluate the company’s financial position and valuation.

7. Other IPO Risks: Customer and Contractor Concentration
Mahanadi Coalfields’ financial performance also depends heavily on the power sector and a relatively concentrated customer base.
The DRHP provides the following FY26 disclosures:
| Risk Indicator | FY26 |
|---|---|
| Thermal power sector share of product sales | 68.62% |
| Top 10 customers’ share of revenue | 55.94% |
| Top 10 contractors’ share of contractual expenses | 60.02% |
The company’s dependence on thermal power producers exposes it to changes in electricity demand, coal procurement policies and energy-sector regulations.
Meanwhile, reliance on major contractors creates potential operational risks involving project delays, service quality and cost fluctuations.
Longer-term considerations include environmental regulations, land acquisition, mine expansion and India’s evolving energy mix.
These risks do not necessarily undermine the company’s existing profitability, but they should be considered alongside its earnings and production scale.
8. Could Mahanadi Coalfields IPO Raise $1 Billion?
Bloomberg reported in early November that Coal India was considering a Mahanadi Coalfields IPO that could raise as much as $1 billion and value the company at up to $10 billion.
The report indicated that investor meetings had begun and that the offering might launch in the second half of November or early December 2026.
However, these are media-reported estimates and a tentative timeline, not officially announced IPO terms.
The final fundraising amount will depend on the offer price and the number of shares ultimately sold.
Investors should wait for the official price band before assessing valuation metrics such as the price-to-earnings ratio.
9. Mahanadi Coalfields IPO: Important Questions
What is the Mahanadi Coalfields IPO opening date?
The official opening and closing dates have not been announced as of November 12, 2026.
What is the Mahanadi Coalfields IPO price band?
The price band and lot size have not been declared. They are expected to be provided closer to the opening of the issue.
Is the IPO an offer for sale or a fresh issue?
The proposed IPO is entirely an OFS of up to 66.18 crore existing equity shares by Coal India. MCL will not receive fresh capital.
Is there a shareholder quota for Coal India investors?
The DRHP proposes a reservation for eligible Coal India shareholders. Final reservation details and eligibility conditions should be confirmed from the RHP.
Is the ₹31,227.80 crore mineral-levy amount a confirmed liability?
No. It is an estimate by Coal India’s legal department cited in a CAG supplementary audit observation. The eventual financial impact remains unresolved.
Will Coal India shareholders automatically receive MCL shares?
No. The proposed IPO is not a demerger or automatic share distribution. Eligible investors would need to apply according to the final offer terms.
Bottom Line: What Matters Before the Mahanadi Coalfields IPO?
Mahanadi Coalfields enters the IPO process with significant business scale, annual profit exceeding ₹10,000 crore and strong operating cash generation.
However, the DRHP also highlights issues investors should examine closely.
Operating EBITDA has declined, margins have narrowed and quarterly production weakened even as coal dispatch increased. The proposed IPO also involves a 10% stake sale by Coal India rather than fresh capital entering MCL.
Additionally, the proposed shareholder reservation and unresolved ₹31,227.80 crore potential mineral-levy exposure are important details that prospective investors should understand.
Ultimately, the final IPO price band and valuation will determine how attractively these business strengths and risks are priced.
Until the final offer terms are announced, investors should treat the proposed listing as an investment opportunity under evaluation—not an automatic subscription decision.
