IST Ltd: 122% Net Margin & 443 Working Capital Days – Auto Components or SEZ Real Estate Masala?

1. At a Glance

IST Ltd is that odd uncle at the family wedding — introduced as an “auto component maker,” but somehow makes more money flipping SEZ rentals and sitting on investments than from actually making pistons or valves. Net margins of 122% scream “something’s off,” but the stock still trades at a humble 6.5× earnings. Almost debt-free, promoters chill at 75% holding, and still no dividend for shareholders. Basically, a company that’s profitable but acts allergic to sharing mithai.

2. Introduction

Incorporated in 1976, IST Ltd started with a simple dream: make high-precision engineering components for India’s booming auto industry. Four decades later, while Bosch and Bharat Forge built global supply chains, IST found enlightenment in the art of making money… not from cars, but from SEZ rentals and treasury income.

Imagine buying a ticket for a cricket match but getting served a fashion show instead. That’s IST. Officially, they make throttle valves, jets, and CNG kit parts. Unofficially, they’re landlords running Gurgaon Infospace SEZ and clipping coupons from investments.

The cherry on top? Their quarterly results look like stand-up comedy. Sales growth over 5 years: negative. Profit growth: double digits. How? Because “Other Income” (read: investments, rentals, dividends) is fatter than their manufacturing topline. It’s like Maruti Suzuki reporting most of its revenue from renting office space.

So, is IST an auto play, a real estate landlord, or a disguised NBFC? Let’s investigate.

3. Business Model (WTF Do They Even Do?)

The official brochure says IST Ltd manufactures high-precision auto components. Their product portfolio includes:

• Piston Cooling Nozzles – tiny parts ensuring engines don’t roast like aloo parathas.
• Throttle Shafts & Valves – basically the lungs of your car.
• Carburetor Assembly Components – because India still loves jugaad in its older vehicles.
• CNG Kit Components – injectors, plungers, silencer bodies — all the kit a Delhi cabbie would bless them for.
• Tractor Components – keeping desi tractors chugging like Bhojpuri songs at a wedding.

So far, so auto. But here’s the kicker: 76% of FY23 revenue came from SEZ rentals, only 24% from manufacturing.

Subsidiaries & Associates:

• Gurgaon Infospace Ltd – SEZ landlord, contributes bulk of revenue.
• IST Steel & Power Ltd – associate with 30.8% holding, does trading of raw materials.

So, IST is essentially three businesses in a trench coat: auto components, real estate SEZ, and financial investments.

Question for you: would you classify IST in auto components or as a glorified landlord? Comment below — I’m still confused.

Annualised EPS = ₹248.
At CMP ₹885, that’s a P/E of 3.6×. Screener says 6.5×, but we’re auditors — we recalc.
