Coal India files to sell 10 percent of Mahanadi Coalfields

Mahanadi Coalfields has filed a draft red herring prospectus with the Securities and Exchange Board of India so that its parent, Coal India, can sell a 10 percent stake. The paper is dated Monday. The proposed issue is only an offer for sale: up to 66.18 crore shares, or 661.8 million shares. No new equity is being created. MCL will not receive any of the proceeds.

The Odisha miner accounted for 21 percent of India's domestic coal production and 28.4 percent of Coal India's production in the year to March 2026. Coal India itself supplied about 74 percent of the country's coal that year. MCL's net profit slipped 1.3 percent to Rs 10,678 crore. Revenue fell 2.6 percent to Rs 30,550 crore.

On Wednesday morning, with the Sensex down hundreds of points, Coal India still rallied as much as 4 percent to Rs 419.70 on the BSE, its sharpest intra-day gain in three months. About 13.32 million shares changed hands on the two exchanges by mid-morning. At 9:42 a.m. the stock was 3.3 percent higher at Rs 415.75 against a 0.80 percent decline in the Sensex.

A listing programme already in motion

In March, Coal India said it could sell up to 25 percent of MCL and of South Eastern Coalfields through IPOs or other routes. Two other units listed this year. Bharat Coking Coal went public in January and is down about 25 percent from its debut. Central Mine Planning and Design Institute listed in March and is up 39 percent.

The filing arrives as India's primary market tries to restart after a weak first half, itself tied to the oil shock from the Iran war. An OFS in a cash-generating miner is easier to price than a growth story. Buyers are buying a share of current production in the Talcher and Ib Valley fields, not a promise of a new business.

Production at the parent is not running hot. Coal India mined 47.5 million tonnes in August. Year-to-date output in FY27 is 268 million tonnes, 5 percent lower than a year earlier. That is the tension inside the prospectus. The government wants listed subsidiaries and a smaller holding. The operating numbers show a large miner in a year when power demand is high and output is a little soft.

What the 10 percent does not change

After the sale Coal India will still own 90 percent of MCL. Control, pricing of coal to power plants, and the social and environmental liabilities in Odisha stay with the parent and the Union government. The listing does give public investors a direct claim on the most productive subsidiary and a mark-to-market price for a business that used to sit inside a single PSU quote.

South Eastern Coalfields is the next name on the March shortlist. If MCL prices well, that paper will follow. If it prices like Bharat Coking Coal, the programme will slow. Wednesday's 4 percent pop in the parent is the market taking the first view: a 10 percent slice of India's second-largest coal producer is easier to sell than the week around it.
