Antero Resources drills for natural gas in Appalachia. Antero Midstream Corporation (NYSE:AM) owns the pipe that takes it away, and it was carved out of that same producer to do exactly that job.
The stock closed at $20.64 on October 16. It has returned -1.1% during the last 6 months, compared to a 10.5% return for the Insider Monkey Billionaire Index and 9.3% for the State Street SPDR S&P 500 ETF Trust.
Of all the revenue it booked in the first half of this year, less than $1 million came from anyone other than Antero Resources. One customer is what a skeptic points at first, and it may also be the strongest thing here. Telling those two readings apart is most of the investment case.

Why the Arrangement Protects the Business:
Gathering systems are built to a specific set of wells. The pipe runs where the drilling is, and once it is laid, the producer has no practical way to move the gas through anyone else’s system without building a parallel one.
That is as close to a captive customer as midstream gets, and it shows in the economics. The operating margin reaches 52.00%. Gathering assets are cheap to operate once they exist.

Why One Customer Is Also the Risk:
A moat that depends on a single producer is only as durable as that producer’s drilling plan. If Antero Resources slows down, there is no second customer to take up the volume, and the pipe sits where it was built.
Earnings fell 8.80% last time out even as revenue rose 8.30%, which is a reminder that fee-based does not mean fixed. Leverage sits at 185.55% of equity, normal enough in midstream and less comfortable when the revenue has one source.
The honest description is that this is not a moat around Antero Midstream. It is a moat around the pair of them, and the company on this side of it does not control the drilling.

What the Market Pays for It:
The market puts a low price on all of it. The shares go for 12.92 times what analysts expect next year and yield 4.36%.
That discount reads like the market pricing the concentration rather than doubting the assets. Whether it is too large a discount depends entirely on how long the wells behind it keep producing.
A discount this wide comes with a single customer attached. 10 Best Utility Dividend Stocks To Buy covers names whose revenue does not rest on one firm.
Conclusion:
The moat is genuine, and it belongs to the relationship rather than to the company. Gathering pipe laid to a producer’s wells is close to impossible to replace, which is why the margins look the way they do. The catch is that the same arrangement removes every alternative, so the investment case rests on one firm’s drilling programme rather than on a market. Watch what Antero Resources says about its wells, because that is the whole of it.
