Tempsens makes temperature sensors, heaters, and special cables for factories. 60% of its sales come from customers who buy more than just sensors
If you already sell sensors to steel or power plants, selling heaters and cables to same plants costs less and earns more. In FY24, heating products were just 4% of revenue. By FY26, that jumped to 21% after company merged in Marathon Heater business.
Total revenue reached โน445 crore in FY26 with 25% EBITDA margin. Raw material costs as share of revenue fell from 62% to 56%
Tempsens is only company in India making non-contact temperature sensors, which are devices that measure heat from distance without touching hot surfaces. It holds 21.3% of that market in India.
Export revenue doubled from โน59 crore to โน126 crore between FY24 and FY26. Company now earns 28% of revenue from countries outside India. It has 15 factories spread across India, UAE, South Korea, Indonesia, Germany, and Poland.
In contact sensors, which are placed directly on hot surfaces, Tempsens holds 10.5% of Indian market
Tempsens IPO collected โน650 crore but most of that money went to promoters selling their own shares, not into company. Only โน95 crore was fresh capital for business use.
Promoters reduced their ownership from 80.5% to 65.7%.
Company has very low debt at just 0.15 times equity and plans to spend โน18 crore on expanding heater and cable capacity.
One thing I have learned from my own experience is how rerating and derating cycles work.
I am not an expert at playing cycles, but let me share what happened with KPI Green.
I bought KPI around Nov Dec 2022.
The market cap was around โน1,500 1,700 Cr and the business was already on track for roughly โน100 Cr+ PAT.
So you were roughly paying 15 17x forward earnings for a business growing very fast.
At that point, KPI had:
232+ MW capacity
1,350+ acres land bank
805+ MW evacuation capacity
128+ MW orders
The growth runway was huge and the market was still relatively early in discovering the story.
Then came the rerating.
FY23 PAT came at ~โน110 Cr.
FY24 PAT jumped to ~โน162 Cr.
But the market cap expanded far faster.
By Apr 2024, the market cap was around โน11,000 Cr and the stock was trading at roughly 65 70x earnings.
So the market was no longer valuing KPI on what it was earning.
It was valuing years of future growth.
I booked around 70 80% of my gains after making roughly 5 6X.
The business was still growing. That was not the reason to sell.
The reason was valuation.
In 2022 the question was:
How big can this business become?
In 2024 the question had become:
How much of that future growth is already priced in?
I kept a small position for momentum and added again later in 2026.
But eventually the business and the entire theme went through a derating.
And that is the biggest lesson for me.
Multibagger returns usually come from 3 things working together:
Low starting valuation
Long growth runway
Earnings growth + rerating
But the same thing works in reverse.
When growth becomes consensus, valuations become stretched and the market starts demanding more from every quarter, the risk reward starts changing.
A great business can still be a poor investment at the wrong valuation.
For me, the goal is not to sell just because a stock has gone up.
It is to recognise when the rerating has already happened and the next phase of returns depends almost entirely on earnings catching up with the valuation.
Rerating gives you the turbo.
Earnings growth drives the journey.
Derating can take away a big part of the return.
Neem Karoli Baba will make it happen. Not only in collections which is an unintended consequence. But in the way people watch quietly in an Indian cinema unusually. In the way the audience sit even after the title screen comes on. In the way everyone walks out touched by spirituality. In the way even an atheist's heart feels there's something higher that's guiding him. That is Maharaj ji's way. He's showing the way for a new India. For the new generation. The way back for the masses into spirituality, service, and saintliness of this great civilization. Just in time for the new India that will emerge out of the upcoming chaos and turmoil in the world.
