Mahanadi Coalfields files RHP for Coal India's 10% offer for sale

The Development

Mahanadi Coalfields Limited (MCL), the Odisha-based coal mining subsidiary of Coal India Limited, has filed its red herring prospectus (RHP) for an initial public offering. In a Regulation 30 disclosure to BSE and NSE dated 14 November 2026, Coal India stated that the RHP "dated 13th November, 2026" was filed with the Registrar of Companies, SEBI, BSE and NSE.

The filing pertains to an offer for sale of up to 661,836,300 equity shares by Coal India, per the same disclosure, which adds that the IPO "remains subject to receipt of applicable approvals, market conditions, and other relevant considerations". Against the 6,618,363,000 equity shares outstanding before the offer, per the draft red herring prospectus, the offered shares amount to 10% of the company.

The RHP is the operative offer document and comes after the draft stage, at which SEBI issues its observations. The Economic Times reported the proposed offer at nearly Rs 9,500 crore. That figure has not yet been confirmed by an exchange price-band notice, and the price band, lot size and bid dates had not been checked against an exchange notice at the time of writing.

The Company

MCL was incorporated on 3 April 1992 and has its registered office at Burla, Sambalpur, Odisha. Its promoters are the President of India, acting through the Ministry of Coal, and Coal India Limited, which currently holds all 6,618,363,000 shares, per the draft red herring prospectus (DRHP) dated 31 August 2026. The company was converted into a public limited company in August 2026.

The DRHP states that MCL was the largest coal producer in India in Fiscal 2026, accounting for 21% of domestic coal production (citing a CRISIL report), with annual production of 218.31 million tonnes. As at 30 June 2026 it operated 17 mines, 14 opencast and three underground, concentrated in the Talcher and Ib Valley coalfields. The company discloses audited coal reserves of 9,840.31 million tonnes as at 1 April 2026, which it says would sustain production for around 45 years at the present level.

Per the restated financial information in the DRHP, revenue from operations was Rs 305,495.90 million in Fiscal 2026, against Rs 313,530.20 million in Fiscal 2025 and Rs 316,343.50 million in Fiscal 2024. Profit after tax was Rs 106,981.20 million in Fiscal 2026, Rs 108,251.20 million in Fiscal 2025 and Rs 118,415.50 million in Fiscal 2024. For the three months ended 30 June 2026, revenue from operations was Rs 80,337.70 million and profit after tax Rs 23,987.80 million.

The Offer Structure

The offer is entirely an offer for sale. There is no fresh issue, and the DRHP states that "our Company will not receive any proceeds from the Offer for Sale". Coal India is the sole selling shareholder, offering up to 661,836,300 equity shares of face value Rs 2 each. The DRHP discloses Coal India's weighted average cost of acquisition at Rs 0.26 per share, as adjusted for the share split.

The draft provides for a reservation for eligible employees and for eligible shareholders, with a possible employee discount. Of the net offer, not more than 50% is for qualified institutional buyers, not less than 15% for non-institutional bidders and not less than 35% for retail individual bidders, per the DRHP. The price band, employee discount and minimum bid lot are to be advertised at least two working days before the bid/offer opening date and made available to BSE and NSE. The shares are proposed to be listed on both exchanges.

The book-running lead managers named in the DRHP are SBI Capital Markets, Axis Capital, BOB Capital Markets, IDBI Capital Markets & Securities and IIFL Capital Services. KFin Technologies is the registrar. Readers working through the arithmetic of an allotment can use Oquilia's lumpsum calculator; prior primary-market coverage is on the /news desk.

Risk Factors

The DRHP lists that raw non-coking coal accounted for 97.41% of sale of products in Fiscal 2026, and that sales to the thermal power sector made up 68.62% of sale of products that year. Any decline in that demand, the company discloses, could materially affect its results.

Among the risk factors the company discloses is customer concentration: its top 10 customers accounted for 55.94% of revenue from operations in Fiscal 2026, and government-owned power generators and utilities contributed 44.81%, which the DRHP says exposes it to regulatory scrutiny and delayed collection of receivables. The document also notes that non-coking coal pricing is largely governed by a notified mechanism administered by Coal India.

The DRHP further lists contingent liabilities equal to 39.80% of net worth as at 31 March 2026, not provided for in the financial statements. It also lists inherently hazardous mining operations, reliance on third-party contractors for much of its operating activity, and the concentration of its mines in two Odisha coalfields. It notes that the company is wholly owned by Coal India and controlled by the Government of India.

What Happens Next

With the RHP filed, the next formal step is the price-band advertisement, which the DRHP requires at least two working days before the bid/offer opening date. If the company chooses to take anchor investors, the anchor bidding date is one working day before the issue opens. The bid/offer period then runs for at least three working days, and any revision of the price band extends it.

After the issue closes, the registrar finalises the basis of allotment with the designated stock exchange. Funds blocked under ASBA or UPI for unallotted bids are released, allotted shares are credited to demat accounts, and trading begins on BSE and NSE after the exchanges issue their listing and trading approvals.

FAQ

Should I apply for this IPO?

Oquilia does not make recommendations. This report is informational and is not investment advice or a recommendation to subscribe. The RHP, including the complete risk-factors section, is available on SEBI's website and the exchanges - read it directly before making any decision.

Will Mahanadi Coalfields receive any money from the IPO?

No. The offer is entirely an offer for sale by Coal India, and the offer document states that the company will not receive any proceeds from it. The offer reduces Coal India's holding by up to 661,836,300 shares, or 10% of MCL's share capital.

What are the price band and lot size?

They are not confirmed in this report. Under the DRHP, the price band, employee discount and minimum bid lot are decided by the company with the lead managers and advertised in national and Odia newspapers at least two working days before the issue opens. They are also posted on the BSE and NSE websites.

What does filing the RHP mean?

The red herring prospectus is the legally operative offer document for a book-built issue. It carries the full disclosures but leaves the final price open until the book is built. A draft document reaches this stage only after SEBI has issued observations on it. Those observations are clearance to proceed, not an endorsement of the issue's merits.

Where can I read the offer documents?

The draft red herring prospectus is hosted on the NSE website, and Coal India's disclosure of the RHP filing is on BSE. The RHP itself is filed with SEBI, BSE and NSE, and SEBI publishes red herring prospectuses in the public issues section of its website.

This report is based on Coal India's Regulation 30 disclosure filed with BSE and NSE and the draft red herring prospectus on the NSE website. It was surfaced via coverage in The Economic Times.
