It also holds an estimated 42%–45% share in the cast alloy segment used by the automotive industry.The business is well positioned to benefit from the global shift toward recycled metals, as industries increasingly focus on low-carbon manufacturing solutions. As per the ICRA report, recycled aluminium emits significantly lower greenhouse gases compared to primary aluminium production and requires much lower capital investment.On the financial front, the company reported operating revenue of Rs 6,666 crore in FY25, reflecting a 12% year-on-year growth. Profit after tax stood at Rs 155 crore, recovering from a loss in FY24, which was primarily due to a one-time goodwill impairment charge.Ahead of the IPO, CMR Green Technologies also raised Rs 188 crore from anchor investors, including participation from domestic mutual funds, insurance companies, and foreign institutional investors.Brokerages ReviewAnalysts have offered mixed views on the issue. Motilal Oswal highlighted CMR Green's leadership position in the aluminium recycling industry, its dominant market share and exposure to long-term sustainability and decarbonisation trends. The brokerage noted that the company is benefiting from growing demand for recycled aluminium and expansion into new segments such as extrusion and rolled alloys.Swastika Investmart has assigned a "Neutral" rating to the IPO. The brokerage said the valuation of around 27 times FY25 earnings appears reasonable relative to peers and acknowledged the company's industry leadership and strong market position.However, it flagged concerns around the issue being a pure OFS, customer concentration risks, dependence on a few key clients and relatively thin operating margins. Swastika said high-risk investors may consider the issue primarily from a listing gains perspective.The IPO comes at a time when investor appetite for manufacturing and sustainability-linked businesses remains healthy, particularly in sectors linked to recycling, resource efficiency and the circular economy.(Disclaimer: Recommendations, suggestions, views and opinions given by the experts are their own.
