Ladies and gentlemen, welcome to the rollercoaster known as Rain Industries Limited.
This is a company that turns industrial waste into carbon gold… but somehow keeps struggling to turn revenue into serious profits. In Q4 CY25, it reported Revenue from Operations of ₹43,007 million and Adjusted PAT of ₹512 million for the quarter. For full CY25, revenue stood at ₹169,458 million and adjusted PAT at ₹1,178 million.
But here’s the twist: debt sits at ₹9,824 crore while annual EPS for CY25 is ₹3.50.
P/E of 118.
Interest coverage of 1.47.
Net debt overhang.
And yet the stock is up 36% in three months.
So what is this? A deep value play hiding in plain sight? Or a balance sheet thriller with too many plot twists?
Let’s dissect this carbon empire.
2. Introduction – The Global Waste-to-Wealth Machine
Rain Industries is not your typical “Made in India, sold in India” story.
This company operates across North America, Europe, and Asia. It transforms by-products from oil refineries and steel plants into carbon-based materials essential for aluminium, graphite, carbon black, and specialty chemicals.
In simple language:
Other companies produce smoke and sludge.
Rain buys that sludge.
Refines it.
And sells it back at higher margins.
Brilliant business model. Industrial recycling at scale.
The company operates three business segments:
- Carbon (74% of revenue)
- Advanced Materials (19%)
- Cement (7%)
83% of revenue comes from exports. Europe alone contributes 40%.
Which means two things:
- Forex matters.
- Global demand cycles matter.
And when aluminium prices move, Rain sneezes.
Now here’s the real question:
If they are world’s largest producer of coal tar pitch and second-largest CPC manufacturer… why are margins still unstable?
Let’s find out.
3. Business Model – WTF Do They Even Do?
Let’s break this into three buckets.
1️ Carbon Segment (The Big Daddy – 74%)
This segment converts refinery by-products into:
- Calcined Petroleum Coke (CPC)
- Coal Tar Pitch (CTP)
- Other carbon products
CPC alone contributes 39% of segment revenue.
These are used in aluminium smelting, graphite electrodes, carbon black, TiO2, etc.
In Q4 CY25:
- Revenue: ₹33.0 billion
- Adjusted EBITDA: ₹5.3 billion
Volumes: 659k MT.
Strong calcination demand. But raw material competition from lithium-ion battery players is increasing.
Translation: Battery guys are entering the party.
2️ Advanced Materials (19%)
This is the “value-add” play.
Products:
- Resins (40%)
- Petrochemical intermediaries (25%)
- Naphthalene derivatives (18%)
- Engineered products (17%)
