1. At a Glance – Old Money, New Headaches
Let’s set the mood. Carborundum Universal Ltd (aka CUMI) is the Murugappa Group’s industrial nerd — abrasives, ceramics, electro-minerals, no drama, no glamour, just grinding, polishing, and firing stuff at very high temperatures.
- Market Cap: ₹15,303 Cr
- CMP: ₹804
- 3-month return: -10.7%
- 1-year return: -30.9% (ouch)
- Q3 FY26 Sales: ₹1,291 Cr
- Q3 FY26 PAT: ₹73 Cr
- Trailing EPS: ₹12.68
- ROCE: 16.1%
- Debt: ₹308 Cr (basically harmless)
This is not a YOLO stock. This is the kind of company your CA uncle recommends while adjusting his spectacles. But at 63× earnings, the market seems to think this uncle is secretly a startup founder.
So… is CUMI an underrated industrial compounder going through a bad year, or a legacy business priced like it just discovered AI?
2. Introduction – When Consistency Meets Valuation Hangover
CUMI has existed since before your SIP started. It survived wars, commodity cycles, policy changes, and now… Russia sanctions.
The company operates across abrasives, electrominerals, industrial ceramics, and “others”, with revenue now 54% outside India — a big shift from FY22 when India was still the majority.
FY24 and FY25 were supposed to be steady years. Instead, FY25 TTM profit growth is -46%, margins are under pressure, and Q3 FY26 profits are lower YoY.
Yet the valuation never corrected fast enough.
That mismatch is the entire story of CUMI today.
Before judging, let’s understand what they actually do, because this is not a simple one-product company.
