Central Mine Planning & Design Institute IPO – Complete Details

The Main IPO Story in One Line

CMPDIL IPO is a pure offer for sale by Coal India Limited, where public investors are getting access to a specialised mine-planning and technical consultancy company that has long operated inside the Coal India ecosystem.

There is no fresh issue in this IPO. CMPDIL will not receive fresh funds from the offer. The entire issue is a stake sale by Coal India Limited, which is the promoter selling shareholder.

Seven Numbers That Define CMPDIL IPO

Why CMPDIL Is Not a Regular Coal IPO

A coal producer earns mainly from extracting and selling coal. CMPDIL’s business is different. It provides services that help coal and mineral projects move from exploration to planning, design, environmental review and project execution.

The company works across the early and technical stages of mining projects. Its services include geological exploration and resource evaluation, mine planning and design, environmental services, geomatics, survey services, specialised technology support and management systems.

This means CMPDIL’s business is closer to a specialised engineering and mining consultancy company than a commodity producer. Its revenue depends on exploration activity, mine planning work, Coal India group projects, government-funded schemes and demand for mining-related technical services.

Where CMPDIL Fits in the Mining Chain

CMPDIL’s role begins before a mine becomes fully operational. Before coal or mineral extraction starts, companies and government agencies need geological studies, drilling data, mine plans, environmental assessments, survey maps and project reports.

CMPDIL provides these services across the mining lifecycle. This gives the company a role in the planning and design side of the mining sector, rather than direct production.

The Coal India Connection

CMPDIL is a wholly owned subsidiary of Coal India Limited before the offer. Coal India is also the promoter selling shareholder in the IPO.

This connection is central to CMPDIL’s identity. The company has developed as a technical and consultancy arm within India’s public-sector coal ecosystem. It provides services to Coal India, Coal India subsidiaries, government entities and other mining-sector participants.

The Coal India linkage gives CMPDIL a long operating base and sector relevance. At the same time, it creates concentration risk because a large part of the company’s work is connected with Coal India group entities and government-linked projects.

Offer Structure: Coal India Is Selling, CMPDIL Is Not Raising Fresh Money

CMPDIL IPO is entirely an offer for sale. Coal India Limited is offering up to 10,71,00,000 equity shares through the IPO.

Since there is no fresh issue, CMPDIL will not receive any IPO proceeds. The offer proceeds will go to Coal India Limited as the promoter selling shareholder, after applicable offer-related adjustments.

This makes the IPO mainly a listing and partial stake-sale event. The public issue creates public shareholding in CMPDIL, but it does not bring fresh capital into the company for expansion, debt repayment or working capital.

Employee and Shareholder Reservation

The offer includes separate reservation portions for eligible employees and eligible shareholders. Up to 53,55,000 equity shares are reserved for eligible employees, while up to 1,07,10,000 equity shares are reserved for eligible shareholders.

Eligible employees are offered a discount of ₹8 per share. These reservation portions are separate from the net offer available to QIB, non-institutional and retail categories.

The shareholder reservation is relevant because CMPDIL is a Coal India group company. Eligible shareholders applying under the reserved category need to check the applicable conditions in the offer document and application platform.

How CMPDIL Earns Revenue

CMPDIL reports revenue across four main service verticals. Geological exploration and resource evaluation is the largest contributor. The other verticals include mine planning and design services, environment services, and geomatics and survey services.

For the nine months ended December 31, 2025, CMPDIL reported revenue from operations of ₹1,489.65 crore. Geological exploration and resource evaluation contributed ₹681.92 crore, making it the largest vertical.

Fiscal 2025 Revenue Mix

In Fiscal 2025, CMPDIL reported revenue from operations of ₹2,102.76 crore. The largest vertical remained geological exploration and resource evaluation, which contributed ₹970.84 crore.

Mine planning and design services contributed ₹445.28 crore, environment services contributed ₹359.70 crore, and geomatics and survey services contributed ₹326.94 crore.

The Largest Revenue Engine: Geological Exploration

Geological exploration and resource evaluation is the main revenue engine for CMPDIL. This work includes exploration planning, drilling-related work, resource assessment and geological evaluation for coal and mineral blocks.

In Fiscal 2025, CMPDIL undertook exploratory drilling across 136 blocks and mines spread across 29 coalfields, 3 lignite fields and one non-coal field across 12 states.

This vertical links CMPDIL’s business directly with the pace of coal exploration, mining project development, commercial mining activity and government-funded exploration programmes.

Why the OFS-Only Structure Matters

A pure OFS changes the way this IPO should be understood. In a fresh issue, the company receives money and uses it for defined objects such as expansion, debt repayment or working capital.

In CMPDIL’s case, there is no fresh issue. The company is not raising money for new projects through this IPO. The offer is mainly about Coal India reducing part of its stake and bringing CMPDIL to the public market.

The business case therefore depends on CMPDIL’s existing operations, future work pipeline, Coal India ecosystem, government-linked exploration activity and demand for mining consultancy services.

Valuation Context from the Price Band Advertisement

The price-band advertisement states that the P/E ratio based on diluted EPS for Fiscal 2025 is 17.50 times at the lower price band and 18.50 times at the upper price band.

It also mentions an average industry peer group P/E ratio of 22.6 times for Fiscal 2025 and weighted average return on net worth of 34.8% for the last three financial years.

These numbers give the valuation background for the IPO. They should be read along with the company’s public-sector profile, Coal India linkage, customer concentration, OFS-only structure and service-based revenue model.

Risk Map: What Can Affect CMPDIL After Listing?

CMPDIL’s risk profile is different from a normal manufacturing company. Its risks are linked to customer concentration, government-linked projects, mining-sector activity, vendor dependence, exploration cycles and technology requirements.
