Ion Exchange (India) Ltd Q2FY26 – The Water Baron’s Thirst for Growth Meets a Reality Check (Sales ₹734 Cr, PAT ₹50 Cr, ROE 18.7%, and a P/E Thicker Than a Chennai Monsoon Cloud)
1. At a Glance
Ion Exchange (India) Ltd, the OG of Indian water treatment, just dropped its Q2FY26 numbers — and let’s say the results are more “moderate monsoon” than “flood of profits.” The company clocked a revenue of ₹734 crore and PAT of ₹49.9 crore, down 2.8% YoY, even as sales grew 13.9%. That’s the financial equivalent of running fast but on a treadmill — plenty of effort, not much distance.
The market cap now sits at ₹5,814 crore, while the stock price floats around ₹396, a whole -42.7% lower than last year’s highs (ouch). Yet, management proudly flaunts a ROE of 18.7% and ROCE of 22.3% — numbers that scream operational strength even as the market shrugs like, “Cool story bro.”
Debt has crept up to ₹421 crore, the company has high debtors of 151 days, and the P/E ratio is at 27.7x, about 30% higher than the industry median of 21.4x. In short, Ion Exchange is like that friend who insists he’s fine while holding a half-broken umbrella in a thunderstorm.
Still, with 100,000+ installations across the globe, a ₹3,400 crore order book, and new resin plants under commissioning, the story isn’t dry yet. In water business terms — they’re still making waves, even if the tide’s a bit low.
2. Introduction
Ion Exchange has been India’s water whisperer long before ESG became LinkedIn’s favourite buzzword. From desalination in the deserts to sewage resurrection in metros, the company has been turning “paani problems” into profit since 1964.
But FY25 and Q2FY26 tell a curious story — one where engineering orders swell, chemicals sizzle, yet profits decide to stay at home watching IPL reruns. Despite having 7 manufacturing facilities in India and 4 overseas, Ion Exchange seems to be fighting supply chain leaks and project execution delays that keep margins capped at ~10%.
Still, it’s hard not to respect a company that’s survived for six decades in an industry where clients take three years to pay and governments take five to approve.
The firm’s global footprint spans from Africa to Japan, and its client list reads like a who’s who of industrial India — NTPC, Reliance, IOCL, L&T, and even hotel royalty like Taj, Oberoi, and Hyatt. But lately, the market seems unconvinced, slicing the stock nearly 43% lower YoY.
So, what’s happening? Is the Ion in Ion Exchange losing charge, or is the market just underestimating its chemistry? Let’s get to the data lab.
3. Business Model – WTF Do They Even Do?
Ion Exchange operates in three buckets — literally: Engineering, Chemicals, and Consumer Products. Each contributes its unique flavour of stress to the balance sheet.
Engineering (58% of Q1 FY25 revenue): This is the big daddy segment — EPC contracts for water and wastewater treatment, desalination, zero-liquid discharge systems, and recycling projects. Basically, they build the tech that makes dirty water drinkable and industrial waste look less sinful.
Q1 FY25 saw 13% YoY revenue growth and 26% EBIT growth in this segment, driven by medium-sized job orders and global contracts. Yet, the operating margin has slipped from 11% to 8% in two years — probably because running EPC projects in India can make even seasoned engineers weep.
Chemicals (~30% of revenue): Their resin and specialty chemicals division is the most profitable kid in the family. With 25% margins and 36% YoY revenue growth, this segment is the company’s cash cow. Their new ₹400 crore Roha greenfield resin plant (commissioning started Sept 2025) will boost capacity and hopefully taste sweeter than borewell water.
Consumer Products (12% of revenue): The only part of Ion Exchange where “consuming” water is literal. Despite 9% YoY growth, it still posted a ₹3.4 crore EBIT loss in Q1 FY25. Management’s response? “We’ll reinvest surpluses for growth.” Translation: “Don’t expect profits, expect vibes.”
So, what does Ion Exchange do? Everything water, everywhere, for everyone — from desalinating Gulf oceans to keeping your office dispenser pure. They’re basically India’s water doctor… only with a long patient list and some delayed payments.
