MP Materials' 89% Revenue Surge Is Real. So Is the Contract That Caps It.

On August 6, MP Materials did what investors say they want. America's only rare earth miner reported second-quarter revenue up 89% year over year to $108.5 million, sales of the magnet metal NdPr up 127%, positive adjusted EBITDA of $28.5 million, and a sharply narrower loss. Wall Street is still wearing a Buy sign — an 11-analyst consensus price target near $78, one firm at $81. And the shares popped, then chopped sideways through the high-$50s for the rest of August, giving back gains on analyst target trims and an AI-spending scare, with down sessions in the 5-6% range along the way.

That is not a broken tape. It is the market reading the fine print.

What the 89% actually is

Break the quarter into its parts. Revenue grew because MP finally sells, instead of shipping to China as raw rock, the product that makes EV and wind-turbine magnets work: separated neodymium-praseodymium oxide and metal. Production rose 41% to 840 metric tons; sales rose 127% to 1,006 tons. Notice the disconnect — MP sold 166 more tons than it produced, drawing down roughly 650 tons of inventory while the plant sat idle for April maintenance. Part of the "growth" is a timing effect: a stockpile being monetized, not fresh demand.

Then there is the line most headlines skip. On top of that $108.5 million, MP booked another $17.6 million it labels "PPA income" — a payment from the U.S. government under the price-support deal signed in July 2025. The same line was $42.3 million in the first quarter. In plain terms: a meaningful slice of the revenue surge is a check from Washington, not an arm's-length customer paying market prices.

The deal that made the stock boom also sets its ceiling

Rewind a year. In July 2025 the Pentagon agreed to a package: a $400 million convertible preferred investment (up to around 15% of the company, making the DoD the largest shareholder), a $150 million loan for heavy rare earth separation, backing for roughly a billion dollars of bank financing for a new magnet campus, and 100% offtake of that plant's output for ten years. MP's stock went vertical on the news — from a May low under $20 to about $60 by late July.

The centerpiece is a 10-year price floor: $110 per kilogram for NdPr. If the market drops below that, the government makes up the difference. That guarantee is the source of the PPA income line, and by itself it is a beautiful risk transfer — a floor under the metal for a decade, written by a counterparty that cannot go bankrupt.

Now the strings. Above $110, the same deal shares the upside: the DoD takes 30% of the NdPr price above the floor for ten years once the new plant is at scale, and it takes the first $30 million of that facility's EBITDA above $140 million and half of everything above $170 million. There is also a 10-year warrant. Management's third-quarter outlook says it all: NdPr realized in the high-$90s per kilogram, with roughly $10 per kilogram of government top-up. The contract lands the company at about $110 no matter what spot does.

Here is the plumbing that explains the tape. When Chinese benchmark prices spike to multi-year highs — as they did after MP stopped shipping to China in August 2025 and again as Beijing escalated export controls through 2026 — that headline rally is, at the margin, shared with the counterparty that wrote the guarantee. The marginal dollar of the rare-earth boom does not reach common shareholders at the spot price; it is pegged by contract, and above the peg Washington takes 30%, eventually 50%. A stock that more than tripled on "government-backed American rare earth independence" is now being marked on that net-of-sharing arithmetic — which is exactly how real revenue growth can turn into a shrug.

And it still loses money

Second, revenue is not profit. The quarter ended with a $20.3 million GAAP net loss — 11 cents a share, and an adjusted loss of one cent against the two-cent profit analysts had penciled in. The reason is visible on the balance sheet. MP is spending $500-600 million a year of capital to build the 10X campus in Northlake, Texas — 10,000 tons of magnet capacity a year targeted for 2028 — funded by bank debt, the DoD preferred, and a $1.45 billion cash pile. It shipped prototype magnets to General Motors for testing and guides first commercial magnet revenue in Q4, but the factory that justifies a roughly $10.7 billion market value barely sells anything yet.

Run the math on management's own scenarios: pro-forma EBITDA above $650 million, ranging from around $410 million at low NdPr prices to nearly $790 million if the $110 level holds. Ten-point-seven billion against that is somewhere between 14 and 26 times EBITDA — a multiple that assumes the strategic premium persists and the buildout lands on schedule. Paying up for a strategic near-monopoly is a legitimate bet; just recognize it as the bet you are making.

What to watch

Separate the two businesses inside the ticker. First, a commodity producer with an unusually generous customer: watch realized NdPr price per kilogram and where it sits against the $110 anchor — the floor sets the downside, the sharing caps the upside. Second, a capital-heavy factory in progress: watch cash burn against the $1.45 billion pile, future dilution — the DoD preferred converts into common, and a $1.25 billion buildout rarely ends with one raise — and the EBITDA thresholds where the 50% government share kicks in.

Then the wildcard: China. In June 2026 Beijing added MP itself to its export-control list. Restricted Chinese supply is bullish for Western NdPr prices and for MP's strategic premium; having Beijing target you directly is the kind of policy knife that can whack a 14-to-26-times multiple on any Tuesday. August's AI-capex scare, which dragged rare earths down with the rest of hardware, was the reminder.

The takeaway

Nothing in the August report was bad — that is the whole point. The market's inability to cheer is not a broken quote screen; it is the market reconciling real operational progress with the contract that decides how much of that progress flows to common stock. The floor protects the metal, the sharing caps the boom, and the buildout eats today's earnings. The cleanest frame: you are not buying pure rare-earth price upside. You are buying a government-underwritten buildout of American magnet capacity with a negotiated price ceiling — and a government partner who owns 15% of the company and a share of every dollar above the line. Check the per-kilogram math and the thresholds, and the stock's choppiness stops looking like noise and starts looking like the terms of the deal.
