Core Natural Resources: The Coal Company Building Fighter Jets
The Market Sees A Coal Miner. I See Something Very Different.
"The value of a business is the present value of the cash it will generate between now and Judgment Day, discounted at the appropriate interest rate."
- Warren Buffett
Every year coal sets a new record.
In 2025 the world burned 8.8 billion tonnes of it. An all time high. Because of the events in the Middle East, 2026 will set another all time record. While the financial press wrote eulogies, the black rock kept showing up to work.
I want to tell you about a company that takes this hated, dying, politically toxic rock and does two things with it that should not be possible. It sells it for enormous profit to a world that cannot get enough of it. And it turns it into parts for fighter jets.
This is Core Natural Resources. Ticker CNR.
Two legends got married
Core is not one company. It is two.
In January 2025 two coal giants merged. CONSOL was the king of cheap thermal coal in Northern Appalachia, with one secret weapon, a marine export terminal in the Port of Baltimore. Arch owned the one of best metallurgical coal mines in America. The kind of coal that is geologically rare and impossible to replace.
Neither one alone had the full picture. Together they do. Core digs up Arch’s premium steelmaking coal and ships it to the world through CONSOL’s port. One business balances the other.
And the people running it are not amateurs. When firms merge they always promise cost savings that never appear. Core did the opposite. They promised 110 million in synergies. Then raised it. Then raised it again. It now sits at 150 to 170 million a year. Management delivered more than it said. Remember that. It tells you who you are betting on.
A coal miner that builds aircraft
Before the coal, let me break the stereotype completely.
Core has a division called Innovations. It takes coal mined in West Virginia and turns it into a special carbon material. That material is used to make the tools and molds needed to build military aircraft and spacecraft. This is not a small experiment. The business serves more than 40 customers. Its products have been used in the F-35 fighter jet, the B-21 bomber, and NASA programs.
Sit with that. The market sees a dying coal miner. Some of that same coal is ending up in fighter jets. Nobody is paying a cent for it.
Part One. The thermal coal nobody admits they need
The thesis nobody in polite company will say out loud. Demand for thermal coal is not falling. It is rising. And it will keep rising for two decades.
There are 8.3 billion people on this planet. Roughly 750 million have no electricity at all. Billions more have power that cuts out every day. They do not care about your ESG report. They want lights, refrigerators, a fan when it is 45 degrees outside.
By 2050 the world must electrify another 2 billion people, because the world’s population is going to grow. That is building the entire power grid of China and Europe from scratch in 25 years. You do not do that with solar panels.
China burned more coal in 2024 than the rest of the world combined, and has over 200 gigawatts of new coal capacity under construction. India has 1.4 billion people and uses a fraction of the power per head that the West does. Neither has committed to a phase out. None.
Now add a new buyer. Data centers. AI is devouring electricity faster than anyone predicted, and it needs power at three when the sun is not shining. In much of the world that means coal.
That is CONSOL’s world. The crown jewel is the Pennsylvania Mining Complex, three connected mines holding 529 million tons, around 20 years of life. The coal runs near 13,000 BTU, hotter than most American coal, and Core owns 94 percent of it outright instead of leasing. That is an edge by itself.
Why does CONSOL win? Lowest cost plus the port. In commodities the cheapest producer always wins, because when prices fall the expensive mines die first while the cheap one keeps printing cash. And the Baltimore terminal is the only major East Coast export terminal served by two competing railroads, so the railroads cannot squeeze them. The Baltimore terminal throws off around 60 million a year, and Core also owns 35 percent of a second export terminal, DTA, for even more export capacity.
When the home market is weak they export. When export is weak they sell at home. They can sell wherever the better market is.
Part Two. Arch and the rarest rock in the world
Now the second thesis.
Metallurgical coal is not thermal coal. It is a different animal. You do not burn it for power. You use it to make steel. There is no way to make steel in a blast furnace without it.
And here is the key. Unlike thermal coal, which sits under half the planet, high quality metallurgical coal exists in only a handful of places on Earth. The United States and Australia dominate the premium grades. It is geologically scarce. And there is no economic substitute that can scale. The supply of the good stuff is fixed by geology.
That combination, scarce supply and no substitute and steady demand, is the holy grail of commodity investing. Prices spike violently every few years when supply gets tight. So what does Arch bring to the table? One of the best metallurgical coal portfolios in America.
The trophy is the Leer Complex in West Virginia. Three pieces. Leer, with 29 million tons of reserves. Leer South, with 57 million tons. And an undeveloped expansion called Leer West, with another 84 million tons sitting in the ground waiting. Together that is more than 30 years of life. Leer and Leer South produce High-Vol A coal. This is the special stuff, the binding agent that lets steelmakers mix cheaper coals together. It sells at a premium for exactly that reason.
Then there are the supporting mines. Beckley, a premium Low-Vol mine with about 23 million tons. Itmann, another premium Low-Vol operation with 27 million tons. And Mountain Laurel with about 16 million tons.
