Coal India Files to List Key Subsidiary Mahanadi Coalfields via IPO

Coal India has filed draft papers for an initial public offering (IPO) of its subsidiary, Mahanadi Coalfields, proposing to sell a 10% stake in the unit. The move is part of the state-run parent company's broader strategy to list its key subsidiaries.

According to documents submitted to the market regulator on Monday, the offering will consist entirely of an offer for sale by Coal India. The parent company plans to sell up to 661.8 million shares, with no new shares being issued by Mahanadi Coalfields. This means the subsidiary will not receive any proceeds from the IPO.

Strategic Importance and Financials

Mahanadi Coalfields is a significant contributor to both its parent company and India's energy sector. Operating primarily in the eastern state of Odisha, the subsidiary was responsible for:

• 28.4% of Coal India’s total coal production in fiscal year 2026.
• 21% of India’s total domestic coal production in the same period.

For the fiscal year ended March 31, Mahanadi Coalfields reported a net profit of 106.78 billion rupees ($1.12 billion), a decrease of 1.3% from the previous year. Revenue for the period fell 2.6% to 305.5 billion rupees.

Context and Market Precedent

This IPO filing aligns with Coal India's previously stated plans. In March, the company, which is the world's largest coal producer, announced it could divest up to 25% stakes in both Mahanadi Coalfields and another subsidiary, South Eastern Coalfields.

The offering comes as India's primary market shows signs of recovery after a slow start to the year. Investors will likely look to the performance of Coal India's other recently listed units for context. Bharat Coking Coal, which went public in January, has seen its stock decline about 25% from its debut price, while Central Mine Planning & Design Institute has gained 39% since its March listing.
