CMPDI IPO opens March 20 with a ₹163–₹172 price band, GMP at ₹19, and a Coal India shareholder quota — here's everything you need to know before applying.
The CMPDI IPO is the initial public offering of Central Mine Planning & Design Institute Limited, a Miniratna Category-I PSU and wholly-owned subsidiary of Coal India Limited. CMPDI provides geological exploration, mine planning, and environmental services for coal and mineral projects across India. The offering is entirely an Offer for Sale (OFS) — the company itself receives no fresh capital from this IPO.
The Central Mine Planning & Design Institute (CMPDI) IPO opened for subscription on March 20, 2026. The subscription window closed on March 24, 2026. Allotment was finalised on March 25, 2026. The stock is scheduled to list on BSE and NSE on March 30, 2026.
What Is CMPDI?
Central Mine Planning & Design Institute Limited is a Miniratna Category-I government enterprise. It was incorporated on November 1, 1975. CMPDI is a wholly-owned subsidiary of Coal India Limited (CIL), the world's largest coal mining company and a Maharatna PSU.
CMPDI provides specialised services across the mining value chain:
- Geological Exploration — Drilling, resource estimation, and feasibility studies before mines are developed
- Mine Planning & Design — Pit geometry, production scheduling, ventilation systems for open-cast and underground mines
- Environmental Services — Impact assessments, pollution monitoring, and mine closure planning
- Geomatics & Remote Sensing — GIS mapping, drone surveys, and satellite-based monitoring
Beyond Coal India, CMPDI also works with private sector clients and government bodies like the National Mineral Exploration Trust (NMET). It covers minerals including bauxite, copper, and zinc.
According to the company's Red Herring Prospectus filed with SEBI, CMPDI holds approximately 61% market share in India's coal and mineral consultancy segment as of FY25. Coal India remains its largest client. This relationship is both a commercial strength and a concentration risk for investors.

CMPDI IPO GMP
The grey market premium (GMP) for the CMPDI IPO was approximately ₹11 per share as of March 19, 2026, pointing to an estimated listing price of around ₹183. GMP is unofficial and unregulated. It reflects informal market sentiment and can change significantly before listing. GMP is not a reliable predictor of actual listing price.
Financial Performance
The following figures are sourced from the company's Red Herring Prospectus filed with SEBI.
| Metric | FY23 | FY24 | FY25 | 9M Dec 2025 |
|---|---|---|---|---|
| Total Income (₹M) | 13,987.8 | 17,701.8 | 21,775.3 | 15,439.3 |
| Profit After Tax (₹M) | 2,966.6 | 5,032.3 | 6,669.1 | 4,253.6 |
| EBITDA (₹M) | 3,956.5 | 7,644.4 | 9,157.1 | 5,938.5 |
EBITDA margins expanded from approximately 28% in FY23 to 42–43% in FY24–FY25, per the RHP. ROCE for the nine months ending December 2025 was 27.1%, with RoNW at 20.3%.
Valuation
At the upper price band of ₹172, the stock was priced at approximately 21.65x trailing earnings and 6.01x book value, per the RHP. The premium reflects CMPDI's dominant position in a specialised niche and its government backing. The OFS structure and heavy dependence on Coal India are key factors for investors to consider.
Key Risk to Note
Coal India is CMPDI's anchor client. This is also the company's single largest concentration risk. Any reduction in Coal India's exploration or development activity could directly affect CMPDI's revenues.
