When Bollywood stars and cricketing legends quietly place big bets before an IPO, you can be sure something interesting is going on behind the scenes.
That’s exactly what happened on April 25, 2025, when a group of India’s most recognisable names — Ranbir Kapoor, Aamir Khan, Karan Johar, Jasprit Bumrah, Rohit Sharma, and others — invested ₹105.7 crore in an engineering company that most retail investors had barely heard of.
The company? Karamtara Engineering.
And the moment? A few short weeks before it files one of the most anticipated IPOs in India’s clean energy and infra space.
But this isn’t just a story about celebrity endorsements or flashy headlines. This is a story about a quiet manufacturing giant — one that’s been building the backbone of India’s green future, piece by piece, for over two decades.
Let’s unpack what makes this company worth watching.
The Name Behind the Steel: Who Is Karamtara Engineering?
If you haven’t heard the name before, you’re not alone.
Karamtara Engineering has spent the last 25+ years doing the unglamorous, foundational work that powers our grids, holds up our solar panels, and builds the steel bones of India’s infrastructure.
Headquartered in Mumbai, the company operates eight large manufacturing facilities — seven in India and one in Italy — producing everything from solar module mounting structures and torque tubes, to transmission line towers and high-tensile fasteners. These aren’t consumer-facing products. They’re the nuts and bolts of national development — sold to solar developers, transmission giants, and EPC contractors across 50+ countries.
And yet, despite its low profile, the company closed FY24 with a revenue of ₹2,425 crore and a profit of over ₹102 crore. Quiet. Consistent. Profitable.
Financial Snapshot (FY24)
Karamtara’s growth isn’t just technical — it’s financial too.
| Metric | Value (FY24) |
|---|---|
| Revenue | ₹2,425.15 crore |
| Profit After Tax | ₹102.65 crore |
| EBITDA Margin | Expanding steadily |
| Export Share | 25–30% of revenue |
| Clientele | Top EPCs in US, Europe |
With rising global demand for renewable infrastructure and steel-intensive projects, Karamtara is uniquely positioned.
A Manufacturing Model That Goes Deep
What sets Karamtara apart isn’t just what it makes — but how it makes it.
While many engineering firms rely heavily on third-party suppliers, Karamtara follows a backward-integrated model. That means it handles almost every part of production in-house — from raw material processing to galvanization and finished assembly.
The result? Better control over quality. Stronger pricing power. Higher margins. And most importantly, the ability to scale without bottlenecks.
It’s a model that’s allowed the company to serve large-scale orders for solar structures in North America while simultaneously executing transmission projects in Africa and fastener supply contracts in Europe.
You won’t see this story trending on social media. But institutional investors — and now celebrities — are clearly paying attention.
Celebrities, Capital, and the Pre-IPO Move
The news broke quietly, but it turned heads fast.
On April 25, six high-profile individuals — including Ranbir Kapoor, Aamir Khan, Rohit Sharma, and Jasprit Bumrah — were allotted a combined ₹30 crore worth of equity shares, as part of a ₹105.7 crore pre-IPO placement.
In a market flooded with speculative bets and startup euphoria, this was different.
These were long-term investors backing an industrial manufacturer — not for the flash, but for the fundamentals. And they weren’t alone. The rest of the ₹105 crore came from seasoned HNIs and insiders who clearly believe this IPO has room to run.
It wasn’t hype. It was conviction.
What’s Next: IPO Plans and Global Expansion
The company is now gearing up for its public debut. The Draft Red Herring Prospectus (DRHP) is already filed, with the IPO expected to raise ₹1,750 crore — including ₹1,350 crore in fresh issuance.
But this isn’t just a fundraise. It’s a strategic inflection point.
A chunk of the proceeds will go toward expanding capacity at Karamtara’s Gujarat plant, building a new facility in Saudi Arabia, and adding high-speed galvanization and robotic assembly lines to meet global demand. The company is also entering the wind energy tower segment, expected to go operational by FY26 — a natural next step in its clean energy journey.
And it’s not just about manufacturing. Karamtara is quietly evolving into a global B2B partner for green energy infrastructure, serving everyone from solar OEMs in California to transmission utilities in the Middle East.
Karamtara’s IPO, Expansion & Future Plans
Here’s a snapshot of what’s brewing:
| 🚀 What’s Coming | 📝 Details |
|---|---|
| IPO Size | ₹1,750 crore |
| Fresh Issue | ₹1,350 crore |
| Offer for Sale (OFS) | ₹400 crore |
| Use of Funds | Capacity expansion, debt reduction, working capital |
| Major Expansion | New facilities in Gujarat and Saudi Arabia, entry into wind energy towers |
| Sector Focus | Solar, wind, transmission, structural steel |
This isn’t just a fund-raise — it’s a scale-up plan.
Karamtara is already relocating its solar torque tube facility to Bhuj, increasing structural steel capacity in Gundale, and entering wind energy tower manufacturing — a high-growth, high-margin segment.
The Bigger Picture: Why It Matters to Indian Investors
This IPO isn’t about retail frenzy or FOMO. It’s about India’s deeper transition — from fossil-heavy infrastructure to clean, steel-intensive, energy-efficient systems.
Karamtara is perfectly positioned at that intersection.
As India races toward its 500 GW renewable energy goal and doubles down on transmission modernization, companies like this — quietly powering the shift — could become the real long-term winners.
The celebrity investors may have entered first. But they’ve only added a spotlight to what was already an investment-worthy business.
Final Thought
When Aamir Khan or Rohit Sharma invests in a startup, it’s exciting. But when they bet big on an old-school engineering firm just before it files its IPO, you have to ask: what do they see that the market doesn’t?
And the answer, quite possibly, is this:
A business that’s boring on the surface, but beautifully built for scale, sustainability, and the next decade of India’s growth story.
That’s what Karamtara Engineering represents.
Not hype. Not headlines.
Just the kind of backbone business India needs more of.
While IPOs make the noise, smart investors build portfolios with steady, well-researched picks.
