CMPDI IPO: Should you subscribe?

Summary: Margins of 38 per cent, zero debt, ROCE of 41 per cent. CMPDI looks like a clean business. But 96 per cent of revenue comes from government-linked entities, receivables stretch to 229 days, and the valuation leaves no room for error.

Central Mine Planning & Design Institute (CMPDI) will open for IPO subscription from March 20 to March 24, 2026, excluding the weekend of March 21-22. The issue is a complete offer for sale (OFS) of Rs 1,842 crore, meaning all proceeds go to the selling shareholder, the government, and none to the company itself.

Below is an analysis of the company's business, financials and valuation to help investors decide whether to subscribe.

What the company does

CMPDI is not a mining company. It is a consulting company that makes mining possible, handling everything from the first geological survey of untouched land to the final closure of an exhausted mine. In plain terms, it helps coal and mineral producers, primarily its parent Coal India, figure out how to find, plan and safely extract resources, including coal, bauxite and manganese.

Its revenue comes from four core services:

• Geological exploration and resource evaluation contribute about 46 per cent and cover drilling, testing and mapping. 
• Mine planning and design account for 20 per cent, involving layout design, equipment selection and infrastructure planning.
• Environmental planning and monitoring contribute 18 per cent, ensuring regulatory compliance and land restoration.
• The remaining comes from geomatics and remote sensing, which use satellite imagery, drones and GPS to map mining areas.

How it operates

CMPDI commands a 61 per cent share in India’s coal and mineral consultancy market. This dominance is not purely competitive; it is structural.

A large part of its work is awarded on a nomination basis by the government and Coal India, rather than through competitive bidding. Coal India and its subsidiaries contribute roughly two-thirds of revenue, while government-linked entities account for nearly 96 per cent.

The company operates 58 drilling rigs and eight testing labs across India, forming one of the country’s largest exploratory drilling fleets. However, some of these assets are funded by government grants and legally owned by the Ministry of Coal or Coal India. That means CMPDI cannot treat them as owned assets or collateral.

Operationally, demand exceeds its in-house capacity. In FY25, its own rigs drilled 0.46 million metres, while outsourced vendors handled 0.55 million metres. The top 10 vendors alone account for nearly 31 per cent of total expenses.

Execution also relies on about 1,600 contract workers hired through third parties. This keeps fixed costs low but limits control over ground-level operations.

Financial recap

Revenue grew from Rs 1,386 crore in FY23 to Rs 2,103 crore in FY25, and profit after tax more than doubled over the same period, from Rs 297 crore to Rs 667 crore. What makes this more than a headline story is where the improvement came from.

Employee costs, the largest expense in a consulting business, declined in absolute terms in FY25 even as revenue scaled. Natural attrition reduced the permanent workforce, while incremental field work was handled through contract labour, allowing growth without a matching rise in fixed costs. That shift drove most of the EBIT (earnings before interest and taxes) margin expansion, from 25.6 per cent in FY23 to 38.4 per cent in FY25. Return on capital employed (ROCE) averaged 41 per cent over the three-year period, a strong showing for a business of this scale.

Capital expenditure stayed light at Rs 52 crore in FY25, directed at upgrading drilling equipment and lab infrastructure. The company carries no debt, a clean balance sheet by any measure.

What works in its favour

Built-in demand from Coal India: Coal India is targeting production of 1,000 million tonnes by FY27, which requires opening and expanding 50 mines. Every such project must pass through exploration, mine design, environmental clearance and eventual closure—each a distinct phase of billable work. 

Critically, this work is not tendered: Coal India's expansion programme translates almost directly into a forward order book for CMPDI. Coal India and its subsidiaries accounted for 82.7 per cent of CMPDI's revenue in FY23, moderating to 67.1 per cent in FY25 as third-party work picked up, but remaining the dominant source throughout.

Large pipeline from underexplored blocks: The government has auctioned 136 commercial coal blocks as of January 2026, but only 53 are even partially explored. The private companies that won those blocks still need extensive geological and technical work before extraction can begin. And many of them, spanning captive users, private merchants and foreign players, lack coal mining experience entirely.

For CMPDI, this represents a pipeline of consulting demand that could extend well beyond its captive Coal India relationship.

Early bets on cleaner coal technologies: CMPDI serves as Coal India's principal implementing agency for coal-bed methane extraction, a cleaner fuel trapped within coal seams that would otherwise go to waste and is piloting underground coal gasification, a process that converts deep, unmineable coal into combustible gas without surface extraction.

Revenue from these initiatives is negligible today, but the groundwork is real. If either scales, it offers some extension of CMPDI's relevance beyond the life of conventional coal mining.

What holds it back

Coal’s long-term decline: India's coal production has grown at a 5.6 per cent CAGR over FY15-FY24, crossing 1,047 million tonnes in FY25. But volume growth masks a directional shift: coal's share in new capacity additions is narrowing as renewables take over, and the pace of new mine sanctions will slow as that transition deepens. The adjacencies being developed, mineral exploration and clean coal technologies, are not yet large enough to fill that gap.

Dependence on new mine creation: CMPDI earns at the start of a mine's life, not through its operation. Every contract flows from a decision to open something new, making the business acutely sensitive to the pace of mine sanctioning, which in India has historically been slow and uneven.

Of the 136 commercially auctioned blocks, 125 remain non-operational, and the gap between auction and active exploration has consistently stretched beyond official timelines. The private block pipeline is optionality, not visibility: its value materialises only if conversion timelines improve meaningfully.

Stretched receivables: Dealing almost entirely with its parent and sister companies leaves CMPDI with little leverage to demand timely payment. As of December 2025, the average collection period stood at 229 days. The company effectively finances its own operations while waiting to be paid, a strain that compounds as the business grows and one that shows no structural sign of improving given the nature of the client relationship.

Is the valuation fair?

At the upper price band, CMPDI is valued at 18.4 times FY25 earnings, a premium to Coal India, which trades at roughly half that multiple. The premium reflects its asset-light model, strong margins and high return ratios. Its nomination-driven order book also offers visibility.

However, that same structure limits scalability. Growth is not market-driven, pricing power is not competitive, and revenue depends on a slow-moving pipeline of new mines. Add to that stretched receivables and the long-term uncertainty around coal, and the picture becomes more nuanced.

CMPDI is a well-run business in a structurally strong position. But the valuation leaves little margin for error.

Tracking IPOs is one thing. Knowing which businesses are worth holding after the listing is another.
