Mahanadi Coalfields IPO Approved; Coal India to Sell Up to 25%

Coal India Ltd has received clearance from the Alternative Mechanism (AM) to list its wholly-owned subsidiary Mahanadi Coalfields Ltd (MCL) on the domestic exchanges, the company disclosed in a stock exchange filing dated 15 May 2026. The approval permits Coal India to reduce its 100% holding in the Odisha-based subsidiary by up to 25% through a mix of an offer for sale (OFS) and a fresh issue of equity shares by MCL. Issue size, dates, price band and merchant bankers are yet to be announced; the listing remains subject to SEBI clearance and prevailing market conditions.

Key Facts: Mahanadi Coalfields IPO

What the approval covers

The Alternative Mechanism is an inter-ministerial body that handles disinvestment decisions for state-owned enterprises. The MCL proposal was processed by the Department of Investment and Public Asset Management (DIPAM) and the Ministry of Coal, on the strength of board approvals already granted by Coal India and MCL.

In its filing, Coal India said the approval allows two parallel mechanisms. The first is a fresh equity issuance by MCL as part of the IPO, with the option of follow-on offerings such as FPOs, QIPs or other SEBI-approved routes later. The second is a sale of existing shares by Coal India through an OFS, which can also be carried out in subsequent tranches. The combined reduction in Coal India's shareholding is capped at 25%.

"The disinvestment and capital raising may be undertaken either simultaneously or separately, in one or more tranches," Coal India said in its 15 May exchange filing signed by B. P. Dubey, Executive Director (Company Secretary) and Compliance Officer. The company added that the listing process remains subject to market conditions and completion of statutory and regulatory formalities.

Coal India's board had given in-principle approval for the MCL listing in November 2024, after the Ministry of Coal directed the company to take concrete steps for listing both MCL and South Eastern Coalfields Ltd (SECL). The two are Coal India's largest coal-producing subsidiaries by output.

Why MCL matters in the Coal India group

MCL operates the Talcher and IB Valley coalfields across Odisha's Angul, Jharsuguda and Sundargarh districts, running 15 opencast and three underground mines. The company produced 225.2 million tonnes (MT) of coal in FY25 with dispatches of 210.5 MT, a 9% rise over FY24, per Coal India and MCL disclosures. That output contributed roughly 29% of Coal India's group production.

On financials, MCL reported FY25 revenue of approximately ₹36,606 crore and profit after tax of ₹10,823 crore, on a net worth of ₹18,278 crore, according to Coal India's FY25 disclosures. CMD Uday A Kaole has guided to a production target of 239 MT for FY26.

Coal India shares ended at ₹462.15 on BSE on 15 May 2026, up ₹8.35 or 1.84% over the previous close, on the day the filing was made.

Where this sits in the PSU IPO pipeline

The MCL approval is part of a broader plan to bring Coal India's eight subsidiaries to the exchanges by 2030. Bharat Coking Coal Ltd (BCCL) has advanced its own listing process, and SECL's framework was cleared separately with a different structure that splits the OFS and a smaller fresh-issue component. Among the current mainboard IPOs and the upcoming mainboard IPO pipeline, MCL would rank as one of the largest disinvestments in recent years given its scale of output and profits, if it files its DRHP in this calendar year.

In our view, three execution points are worth watching: (1) the appointment of BRLMs, which typically signals the DRHP timeline within 60–90 days; (2) the eventual split between the fresh issue and the OFS, which determines how much of the proceeds flow to MCL's balance sheet versus the government's exchequer; and (3) valuation benchmarking, since MCL has no directly comparable listed peer at the same scale within Indian thermal coal.

Final Thought

The AM approval is a meaningful clearance, but a long way short of an open-subscription window. The 25% dilution cap, the dual-instrument structure, and the tranche-by-tranche flexibility together set the policy envelope for the transaction. The numbers that move markets — the price band, the issue size, and the fresh-issue versus OFS split — will only become visible when the DRHP is filed.
