Railtel Corpn.

The Toll Booth Beside the Tracks

Picture a man who owns the land running alongside every highway in the country. He didn't buy that land — it came to him for free because his family already owned the road. Now he strings a pipe along it and charges everyone who wants water to flow through. That, in plain Omaha terms, is RailTel. Indian Railways owns the rights-of-way through some 6,000 stations, and RailTel laid its fibre-optic cable along those tracks. No fighting with farmers over easements, no digging up city streets for permits — the corridor was already theirs.

That is a rare thing, and Charlie would tell you to pay attention when a business gets a head start nobody else can copy. You cannot lay a second set of railway tracks across India to compete. The moat here isn't cleverness; it's the map.

A Grower Wearing a Utility's Coat

Most people file "PSU" under "sleepy," and most of the time they're right. But look at what this one has actually done. Sales went from ₹482 crore in 2015 to a run-rate now pushing past ₹4,000 crore — that's the top line more than eight-folding while the world called it a boring government outfit. The ten-year compounded sales growth sits near 22%, the five-year around 26%, and the most recent three years closer to 30%. That is not the arithmetic of a utility falling asleep at the switch. That is a company selling data centres, VPN links, and telecom plumbing to a nation that suddenly cannot live without bandwidth.

Now here is the part I like best, and the part that separates the wonderful from the merely growing. It did all of this without printing a single new share. The equity capital has sat flat at ₹321 crore since 2016 — same slice of pie, just a bigger pie every year. When a company grows sales five-fold and never once asks you to chip in more capital or dilutes your ownership, that is management treating your rupee as their own. Compare that to the serial diluters we've warned you about elsewhere, who grow the business and shrink your share of it in the same breath.

The returns confirm the story isn't smoke — ROCE of nearly 23% and ROE of 17% on a company that's almost entirely debt-free. It even hands back a quarter of its profit as dividend, giving you a yield of about a percent while you wait.

What Mr. Market Is Offering Today

Here's the reason we're writing now rather than two years ago. The stock has fallen roughly 29% over the past year — from ₹413 down to the ₹283 you'd pay today. Mr. Market, in one of his moods, has decided to mark down a business that is still growing its profits.

The price tag is 24.9 times earnings. Against its own history, that's the interesting bit: this stock has traded at a five-year median of 31 times and a ten-year median of 29 times. So you're being offered it at roughly a fifth cheaper than its own five-year habit, and about 15% below its ten-year one. We're not buying a wonderful business at a fair price here — we're buying a fast-growing one at a *discount to its own normal.* That is precisely the pond the "Value with Growth" boat likes to fish in.

Charlie's Cold Water

Now let me hand the microphone to my partner, because he'd never let this pass without a caution.

First, the government owns nearly 73% of this, and it isn't going anywhere. When your controlling shareholder is the State, dividends and business decisions can serve masters other than the small owner. You are a passenger, not the driver.

Second — and this is the number that made Charlie frown — the company takes 175 days to collect its bills. Almost half a year. When your biggest customer is the government machinery, cash can crawl. Profit on paper is fine; profit in the bank account is finer. Watch those receivables like a hawk; a business that books sales it struggles to collect is telling you something.

And invert it, as Charlie says: what kills this? A PSU that becomes a jobs programme instead of a business, or one that keeps piling up uncollected dues. Neither is visible yet, but neither is impossible.

The Verdict from the Porch

You have a debt-free Navratna sitting on an un-buildable moat, compounding sales north of 20% for a decade, never diluting its owners, throwing off a dividend, and — right now — on sale below its own historical price. The receivables are the wart on an otherwise handsome face. For the patient owner with a three-to-five-year horizon, this is the kind of unglamorous compounder that rewards the fellow who buys when the crowd has looked away.
