Ion Exchange diversifies beyond water treatment to target semiconductors and lithium extraction

Ion Exchange India is shifting its strategic focus from traditional water treatment to expanding into high-growth sectors such as semiconductors, data centres, and lithium extraction, supported by diversified product offerings and recurring service contracts, while investor optimism persists despite mixed financials in consumer segments.

Ion Exchange (India) is trying to recast itself as more than a conventional water-treatment company, with a wider mix of resins, membranes, speciality chemicals and recurring service contracts now sitting alongside older engineering work. The strategy also reaches into newer demand areas such as semiconductors, data centres and lithium extraction, where ultra-pure water and specialist treatment systems are becoming more important as industrial water rules tighten and zero liquid discharge standards spread across heavy industries.

That broader story sits behind a business that still looks richly valued. Trade Brains said the stock recently closed at Rs.374.55, giving the company a market value of about Rs.5,493.40 crore and a price-to-earnings ratio of 53.55. Moneycontrol’s ratios page also shows the stock trading on a high earnings multiple, underlining how much future growth the market is already pricing in.

The company has also reshaped its reporting into five units: Treatment Solutions, Industrial Products, Lifecycle Services, Speciality Chemicals and Consumer Products. That change matters because it separates one-off project revenue from steadier, higher-quality income streams. Trade Brains said Treatment Solutions grew from Rs.488 crore in FY22 to Rs.1,122 crore in FY26, while Speciality Chemicals rose from Rs.558 crore to Rs.868 crore over the same period, suggesting both are scaling rather than merely benefiting from isolated contracts.

One of the stronger parts of the group is Lifecycle Services, which includes maintenance, repair, rehabilitation work, spare parts and build-own-operate arrangements. Trade Brains said revenue in that division climbed from Rs.198 crore in FY22 to Rs.289 crore in FY26, while EBIT more than doubled to Rs.38 crore. With more than 1,100 service contracts and over 200 operations and maintenance agreements, it looks closer to an annuity business than a pure project business, which could help smooth earnings over time.

The consumer-facing ZeroB arm presents a less comfortable picture. Revenue has grown quickly, from Rs.115 crore in FY22 to Rs.343 crore in FY26, but EBIT losses have persisted and widened over time, reaching Rs.10 crore in FY26 after peaking at Rs.15 crore in FY25, according to Trade Brains. The company has pointed to value engineering and margin improvement as priorities, but the numbers suggest investors will want proof that scale is finally translating into profit. For now, the newer bets on semiconductors, data centres, hydrogen and lithium remain more of an option on future demand than a measurable earnings driver.
