Central Mine Planning & Design Institute (CMPDI), a subsidiary of Coal India Limited, has opened its Initial Public Offering (IPO) for subscription from March 20 to March 24, 2026. The book-built issue is entirely an offer for sale, with 10.71 crore equity shares on the block, amounting to ₹1,842.12 crore. The price band is set at ₹163–₹172 per share.
Grey market activity indicates a positive investor sentiment, with CMPDI shares trading at a 2.33% premium at ₹176 on March 19, exceeding the upper price band by ₹4 per share. Final allotment is expected on March 25, 2026, with tentative listing on BSE and NSE on March 30, 2026.
CMPDI, incorporated in 1974, is a leading consultancy firm in coal and mineral exploration, mine planning, and design. It also offers services in environmental management, infrastructure engineering, and specialised technology solutions. As of FY25, CMPDI held a dominant market share of 61% in India’s coal consultancy sector and operates seven regional institutes across key coal-producing states. The company also runs eight advanced laboratories for coal testing and mineral analysis.
The IPO is an offer for sale, with proceeds going to existing shareholders, including Coal India and the Government of India through the Ministry of Coal. CMPDI has shown strong financial performance, with revenues rising from ₹1,398.78 crore in FY23 to ₹2,177.53 crore in FY25, and PAT increasing from ₹296.66 crore to ₹666.91 crore during the same period. Its return on net worth stands at an impressive 36.7%, reflecting high profitability.
CMPDI’s strong infrastructure, multidisciplinary services, and government backing make it a strategic player in India’s mining consultancy space. While investor attention should consider client concentration and government dependency risks, the IPO offers a unique opportunity to invest in a financially robust, technically advanced, and market-leading organisation.
