Ranchi-headquartered Mini Ratna (category I) firm Central Mine Planning & Design Institute (CMPDI) is coming with a ₹1,837.84-crore IPO on Friday, March 20. This is after the government directed Coal India Ltd (CIL) to list all its subsidiaries by 2030 as part of a broader push to improve governance, transparency and value discovery.

The public issue is an offer-for-sale (OFS) of up to 10.71 crore shares, i.e., an offloading of a 15 per cent stake, at a price band of ₹163-172/share (excluding the ₹8/share employee discount).

The company has informed the bourses that it allocated 2,73,10,500 equity shares at Rs 172 per share to anchor investors. Some of the marquee institutions that participated in the anchor include Life Insurance Corporation of India, BNP Paribas Financial Markets - ODI, Citigroup Global Markets Mauritius Private Ltd, General Insurance Corporation of India, Goldman Sachs Bank Europe SE - ODI, ASAS Global Fund Incorporated VCC Sub Fund and Edelweiss Life Insurance Company.

Unlike many other wholly owned subsidiaries of CIL, such as BCCL, which conducted its IPO in January 2026, CMPDI is not a miner. As a specialised mining consultancy, CMPDI is the technical brain behind much of the mining industry. If a miner wants to know where to mine, how to mine, how deep to go, what the reserves are, what clearances are needed and how the project should be designed, etc., the over 50-year-old CMPDI is the kind of specialist consultant it hires. This makes CMPDI different from listed public-sector consultants such as RITES Ltd. (rail infrastructure) and Engineers India Ltd. (primarily serving oil and gas and petrochemical engineering).

CMPDI investors will be betting on technical capability, long client relationships, execution credibility and continued spending on exploration and mine development. Despite environmental concerns, coal has re-emerged as a crucial backstop for power security. It offers dependable domestic supply at a time when geopolitical shocks can disrupt oil and gas flows and renewable-heavy systems still face intermittency and oversupply-balancing challenges.

At the upper end, the IPO values zero-debt CMPDI at a trailing P/E of 17.5x and a trailing EV/EBITDA of 11.3x. This is a reasonable valuation relative to RITES (23.9x and 11.3x) and Engineers India (18.3x and 15.7x), given the mining consultant’s faster revenue and profit growth, superior margins, balance sheet strength, better return ratios, and market dominance. Management is confident it can sustain historical growth rates.

All this, however, does not make the IPO attractive in and of itself. CMPDI’s strongest advantage could also be its biggest risk. It is a high-quality, structurally concentrated, government-linked mining consultancy whose economics are supported by deep CIL relationships, public-sector demand, and a niche technical position. That model can work very well, but it also deserves some restraint due to the aforementioned issues, including stretched trade receivable cycles.

RITES and Engineers India show that PSU consultancy stocks do not always rerate immediately; in today’s fragile, geopolitics-hit market, CMPDI may suit patient investors better, given its stronger financial profile and reasonable valuation. Subscribe to the IPO only if you are comfortable with a government-linked, client-concentrated technical consultancy and are not applying for listing gains.

Business profile

With over 2,650 staff, CMPDI offers consultancy and support services across the entire spectrum of coal and mineral exploration, as well as mine planning and design. It has established 7 regional institutes positioned near key mining and natural resource-holding locations.

CMPDIL operates one of India’s largest coal-exploration infrastructure, comprising 58 drills, advanced geophysical tools, eight labs, and drone- and LiDAR-based surveying capabilities. In addition to using Big Data analytics, CMPDI is also developing infrastructure for critical minerals, including rare earth elements.

Its services are primarily for the coal industry, but are also for other minerals such as lignite, bauxite and manganese. It is one of the largest coal and mineral consultancy companies in India, with a 61 per cent market share in FY25, and is the preferred consultant for CIL.

Services span the entire lifecycle of mining operations, from initial exploration to mine closure. Project timelines typically range from 10 business days to up to 3 years. There is no standard rate for complex jobs; concessions vary based on the scale and complexity of the work. Specific services, such as surveys and laboratory tests, have defined rates and are typically non-negotiable.

CMPDI classifies its business into 4 buckets: geological exploration and resource evaluation (46 per cent of revenue), mine planning and design services (21 per cent), environment services (17 per cent), and geomatics and survey services (16 per cent). Geological exploration and resource evaluation identify and assess mineral deposits; mine planning and design prepare mine layouts and extraction plans; environmental services handle clearances, compliance, and monitoring; geomatics and survey services provide mapping, spatial data, and field measurements.

Exploration and mine planning together account for a lion’s share of the mine consultancy market, which fits well with CMPDI’s service mix. India’s coal production is estimated to rise from 997 million tonnes in FY24 to 1,514 million tonnes by FY30, with Coal India still expected to hold around 73 per cent market share by FY30, as per CRISIL. Fifty upcoming Coal India mines/expansions through FY30, higher activity in commercial coal blocks, rising expenditure under the National Mineral Exploration Trust, and policy support for critical minerals through the National Critical Mineral Mission imply ongoing business demand for CMPDI.

But CMPDI’s strongest advantage could also be its biggest risk. It is deeply embedded in the Coal India ecosystem and many government-related entities. For years, that relationship has given it recurring work, credibility, visibility and scale. For a technical-services business, such anchoring can be a major moat. Investors need to resist the easy assumption that dependence equals safety.

While revenue dependence on Coal India and its subsidiaries has dropped, they still accounted for 66 per cent in the nine months ended December 2025. The broader concentration is even sharper. The top 10 clients contributed 93.8 per cent while government entities or agencies accounted for 96 per cent in the nine months ended December 2025. This means CMPDI is not only a Coal India-linked company; it is overwhelmingly a government-system-linked company.

All this brings both stability and vulnerability. It can support a steady workflow, but it also ties CMPDI to government procurement cycles, policy priorities, funding flows, delayed approvals and payment discipline that may differ from those of a private diversified consultancy.

Financial profile

CMPDI’s recent financial performance is the clearest positive in the IPO. Revenue from operations rose from ₹1,386.1 crore in FY23 to ₹1,732.7 crore in FY24 and ₹2,102.8 crore in FY25, which is a healthy CAGR of about 23 per cent. In the nine months ended December 2025, revenue was already 9 per cent y-o-y up at ₹1,489.7 crore. Most government approvals and contracts come through late in the financial year, lifting last-quarter execution, billing and revenue in line with client budget cycles.

Operating EBITDA has more than doubled from ₹382.9 crore in FY23 to ₹840.9 crore in FY25, a CAGR of 48 per cent. This was driven by massive margin expansion (27.6 per cent to 40 per cent), helped by optimisation of employee benefit expenses (which as a share of operational revenue dropped from 50 per cent in FY23 to 30.6 per cent in 9MFY26).

Finance costs are negligible, which aligns with the debt-light profile. 9MFY26 operating margin stood at 36.2 per cent.

Profit growth has been stronger than revenue growth. PAT increased from ₹296.7 crore in FY23 to ₹503.2 crore in FY24 and ₹666.9 crore (30. 6 per cent net profit margin) in FY25. In 9MFY26, profit after tax stood at ₹425.4 crore (27.6 per cent), against ₹390 crore in the comparable prior period.

Other income (₹75 crore annually) has also been meaningful, supported by interest income on deposits and some write-backs, which means some profitability support comes from treasury income. Cash and cash equivalents, other bank balances & surplus financial assets are over ₹ 1,400 crore, accounting for over 11 per cent of CMPDI’s m-cap (at the IPO price).

Capex has been modest, which fits the picture of a field-heavy but still relatively asset-light technical services business. Because operating cash flow has been much higher than capex, free cash generation looks healthy.

Trade receivables were ₹824.98 crore in FY23, ₹987.05 crore in FY24, ₹947.15 crore in FY25 and ₹924.69 crore as of December 31, 2025. Trade receivable days were 216 in FY23, 191 in FY24, 168 in FY25, 247 in December 2024 and 229 in December 2025. Those are long collection cycles for a consultancy business. While this may be defensible if one assumes government-linked counterparties are safe from default, but it does not solve the problem of delay. A receivable can be safe from credit loss and still be a drag on cash conversion and valuation. Some relief may come from strict enforcement of CIL’s circular that requires subsidiaries to pay 75 per cent of CMPDI’s bill value within 15 days.

Valuation, risks

At the upper end, the IPO values zero-debt CMPDI at a trailing P/E of 17.5x and a trailing EV/EBITDA of 11.3x. This is a reasonable valuation compared with RITES (23.9x and 11.3x) and Engineers India (18.3x and 15.7x), as per Bloomberg. This should be viewed in the backdrop of the mining consultant’s faster revenue & profit growth, superior margins, balance sheet strength, better return ratios and market dominance.

While the valuation is reasonable, it is not outright cheap. The peer set is not perfectly comparable. Engineers India is more closely linked to oil and gas and petrochemical engineering. RITES has a rail infrastructure consultancy. Plus, both peers have 43-44 per cent of their revenue from non-consultancy businesses, such as EPC. Since their IPOs, they have also underperformed markets.

CMPDI is a mining and coal-sector consultancy with much deeper government and promoter concentration. If CMPDI were more diversified by client and had cleaner receivables quality, the same earnings profile might justify a more assertive premium.

Below are the key risks investors should understand.

The first and biggest risk is customer concentration. If nomination-based award of work changes, if Coal India’s spending priorities shift, or if project pipelines slow, CMPDI will feel the pinch.

The second risk is government dependence. Most of the revenue across the disclosed periods came from government entities or agencies. The company also depends on funding channels such as the Central Sector Scheme for coal exploration and the NMET for mineral exploration. This makes CMPDI exposed to budget allocations, policy decisions, clearances and administrative processes in a way that private-sector diversified consultancies are not.

Third, long receivable days, ageing balances, and group-linked receivables may lead to slow cash monetisation of profits.

Next, as of 9MFY26, the company has reported contingent liabilities of ₹210.8 crore (32 per cent of FY25 PAT). If a significant portion of these liabilities materialises, it may adversely affect P&L.

Lastly, investors should note the structural sector linkage. CMPDI has opportunities in critical minerals, environmental services, commercial coal blocks, and digital mining tools, but its core remains closely tied to coal and mining. If the long-term energy mix shifts faster than expected, or if environmental and regulatory constraints intensify, the pace of mining-related consultancy demand could change.

Thus, only long-term oriented investors should subscribe to the CMPDI IPO.
