It makes one part. Sells it to one industry. And half its revenue rides on a single customer.
Drive over a pothole and something quietly complicated happens.
The engine is spinning. Power has to reach the wheels. But the wheel is bouncing up and down over the bump — and if you're turning, swivelling sideways at the same time. So the shaft carrying power to that wheel has to bend, stretch and rotate all at once, and still deliver power evenly. If it doesn't, you feel it as a shudder through the steering.
The part that solves this is called a constant velocity joint. Every front-wheel-drive car has four of them. Together with the shaft joining them, that's a driveshaft.
And there's a fair chance the one in your car was made in Faridabad, by a 41-year-old company you've never heard of.
Meet GKN Driveline (India) Limited.
It makes one thing. Driveshafts. And it sells to exactly one kind of buyer — carmakers. Not to you, not to your garage, not to a spare parts shop.
But here's the bit that makes this business different. It doesn't really sell driveshafts. It wins them.
Years before a car launches, the carmaker picks a supplier for that platform. Whoever wins supplies every unit of that model for as long as it's built — six years, eight, sometimes ten. No repeat pitching. No annual tender. You win once, then you deliver for a decade.
Which is why the awards buried in the annual report matter more than they look:
Toyota's Zero PPM award — won for the tenth time
Renault-Nissan's Level-1 rating — held eleven straight years, with a perfect 100/100 score
Maruti's Green Status at the Oragadam plant — fourth year running
Those aren't trophies for the lobby. They're the reason a rival can't walk in and undercut them mid-platform — swapping a driveshaft supplier means revalidating the entire assembly.
Two quirks in the economics are worth knowing:
The customer pays for the tooling. Dies, jigs and fixtures for each part are funded by the carmaker, not the company. That's ₹14.55 crore of revenue that costs nothing in capital.
Steel is a pass-through — eventually. Steel is half the cost base and contracts run a decade, so price swings get recovered from customers. But the fine print says that recovery is booked only after prices are settled. Cost hits now. Money arrives whenever the negotiation ends.
And the quick facts:
Five plants — Faridabad, Dharuhera, Oragadam, Pune, Kadi — each parked next to a customer cluster
97.03% owned by GKN Driveline International GmbH, Germany. Barely 3% floats freely, which is why the unlisted market for this stock is thin. The ultimate parent changed hands in February 2026, when Dauch Corporation — formerly American Axle & Manufacturing — bought Dowlais Group plc.
41 years old, incorporated July 1985
One customer accounts for 53.38% of revenue.
That's Maruti Suzuki. The rest of the list reads well — Toyota, Tata, Renault-Nissan, Bajaj, Honda, Fiat — but half this company rides on a single relationship.
Which is a moat and a cliff at the same time.
All figures in ₹ crore.
| FY26 | FY25 | Change | |
|---|---|---|---|
| Revenue | 1,155.24 | 1,091.75 | +5.8% |
| Gross profit | 564.02 | 519.36 | +8.6% |
| Gross margin | 48.8% | 47.6% | +125 bps |
| EBITDA | 208.99 | 175.10 | +19.4% |
| OPM | 18.1% | 16.0% | +205 bps |
| PAT | 122.78 | 97.18 | +26.3% |
| NPM | 10.6% | 8.9% | +173 bps |
Look at how the percentages stack. Revenue up 5.8%, gross margin up 125 basis points, operating margin up 205, net margin up 173. Each layer of the P&L adds a little more than the one above it. Textbook operating leverage.
So where did it come from?
| As % of revenue | FY26 | FY25 |
|---|---|---|
| Raw material | 51.2% | 52.4% |
| Employee cost | 13.7% | 13.1% |
| Other expenses | 18.1% | 19.2% |
Raw material is the swing factor. It fell 120 basis points — and on ₹1,155 crore of revenue, that alone is worth about ₹14 crore of profit. Roughly half the entire ₹28 crore improvement in pre-tax profit.
Nothing clever happened there. Steel simply got cheaper.
Now split the revenue by where it came from, and the year looks very different.
| FY26 | FY25 | Change | |
|---|---|---|---|
| Domestic | 1,017.35 | 1,017.71 | −0.03% |
| Exports | 114.91 | 53.47 | +115% |
Domestic sales didn't grow. Not slowly — at all. They came in ₹36 lakh lower than last year on a base of over ₹1,000 crore.
The entire ₹63 crore of revenue growth came from exports, which more than doubled. And those exports mostly go to sister GKN plants in Japan, Brazil, Spain, the US, Thailand and Germany — meaning the growth came from within the group, not from winning new customers in the open market.
One. They grew slower than their own market. Indian auto retails grew 13.3% in FY26. This company grew 5.8% — and as we just saw, none of that came from India. A Maruti programme worth 100,000 sets got pushed to December 2026, which explains part of it, but not all.
Two. Part of the profit came from the parent, not from operations. "Other expenses" looks flat at ₹209 crore. It isn't. Inside that line, charges paid to the German parent — trademark fees, management consultancy, strategic charges — fell ₹13.38 crore. Meanwhile real operating costs went up by roughly the same amount: power, freight, jobwork, repairs, travel. The two cancelled out.
So a slice of the margin story is simply the parent deciding to bill its Indian subsidiary less. That's a related-party pricing call. It can reverse.
Three. Cash went the other way. Profit rose 26%. Free cash flow fell 35%, from ₹79.22 crore to ₹51.65 crore. Receivables and inventory swallowed ₹37.82 crore, and capex jumped 62%. Return on capital employed didn't budge — flat at 0.40x — even as return on equity climbed.
The extra profit went into receivables and the bank account, not into making more stuff.
The balance sheet, to be fair, is spotless. Zero debt. ₹88.80 crore of cash. ₹80 crore of untouched credit lines.
The shares aren't listed, but they trade in the unlisted market.
| Price | ₹1,725 |
|---|---|
| Market cap | ₹2,203 Cr |
| Book value | ₹323.08 |
| P/E | 17.94 |
| P/B | 5.34 |
| ROE | 29.75% |
| Debt / Equity | Nil |
The maths ties back cleanly — 17.94 is just ₹1,725 over FY26 earnings of ₹96.12 a share.
Driveshafts don't vanish in an electric car — power still has to reach the wheels. But every platform transition puts the contract back up for grabs.
And here's a number the report includes without connecting the dots. In India's EV market, Tata holds ~39%, MG ~28% and Mahindra ~25%. Maruti — the customer supplying half this company's revenue — holds 1.7%.
Tata and Mahindra don't appear anywhere in GKN's list of business wins or quality awards.
So what you have is a debt-free, cash-generating, quality-obsessed component maker with a 41-year track record and genuinely sticky customers — that grew at less than half its industry's pace, leaned on cheaper steel and a friendlier parent for its margin gain, and is heavily tied to the one carmaker losing the EV race.
Whether that's cheap at 18 times earnings depends entirely on which half of that sentence you believe more.
