MP Materials (MP) Q3 2026 earnings review
MP's magnets pass GM's test, but its sales stop growing
GM has approved MP Materials' first magnets, but the mine that pays the bills earned no more than last quarter. Revenue rose sharply from a year ago, lifted by a one-off $32 million sale of stockpiled material. Without it, revenue plus the government's price-floor payment slipped 1.5% from last quarter by our math, as that payment shrank.
| Revenue plus price-floor income, excluding a one-off sale | $124M −1.5% from last quarter, by our math |
|---|---|
| Revenue | $147.7M +176% from a year ago |
| NdPr produced | 1,018 tons +41% from a year ago; a record |
| Fourth-quarter outlook | New: about 1,000 tons at about $100/kg level with this quarter |
⚖️ Verdict: ⚪ Neutral
The story is unchanged, because the main milestone arrived but the profit from it moved further out. GM's approval removes the risk of a missed deadline, and Mountain Pass set a production record. The caution: finance chief Ryan Corbett expects magnet profits to stay small through 2027, and plans NdPr income level with this quarter.
The question now is whether magnets earn enough in 2027 to matter before a second plant opens in 2028. Either GM takes magnets fast enough to offset the fading metal prepayment, or the division's profit sits near zero for a year. February's fourth-quarter report gives the first reading.
🐂 Bull Case
GM Has Approved MP's Magnets for Sale
MP Materials has spent five years building a magnet factory in Fort Worth, Texas, that it calls Independence. General Motors is the first customer, and until now GM took only test magnets while it checked the plant. Chief executive James Litinsky said the quarter marks "an inflection point" for the business.
GM has now approved the magnets, so paid deliveries begin this quarter. Finance chief Ryan Corbett expects volumes to "build gradually, starting quite modestly over the next couple of quarters". A bigger step comes in the second half of 2027, when production for Apple also starts. Apple has already paid $80 million of a planned $200 million in advance.
The approval removes the risk that the plant would miss its deadline, but it does not show what a magnet earns. Corbett declined to give volumes or prices, and he expects the division's profit to stay small through 2027.
What to watch: the magnet revenue figure in the fourth-quarter results in February. It will show whether GM is taking magnets into real car programmes or still buying test quantities.
Mountain Pass Set a Production Record
Mountain Pass, the California mine and refinery that supplies almost all of MP's revenue, produced a record 1,018 tons of NdPr oxide. NdPr is the pair of rare earths that permanent magnets are made from. Operations chief Michael Rosenthal said the plant ran at "over 450 tons per month" for part of the quarter.
That rate matters because 450 tons a month is close to the 500 tons Rosenthal wants from the existing equipment. He plans an "over 5,000 ton per annum production rate for the year" in 2027. The reliability problems have not gone away, though. Rosenthal said "a small number of circuits experienced unplanned maintenance activities and equipment-related interruptions".
- Production: 1,018 tons, up 41% from a year ago
- Sales: 1,020 tons, up 94% from a year ago
- Concentrate output at the mine: 12,887 tons, down 3%
- 2027 plan: about 1,250 tons a quarter by our math, 23% above this quarter
What to watch: fourth-quarter production, after a planned maintenance stop of 10 to 14 days in October. A figure near this quarter's would confirm that the higher running rate is real.
Heavy Rare Earth Output Starts This Quarter
MP has stockpiled the heavier rare earths it separates while it built a plant to refine them. Dysprosium and terbium go into magnets that must work at high heat; China controls most supply. Litinsky said "the commercial scale production of dysprosium and terbium will begin this quarter, Q4".
The stockpile has already earned money. MP sold $31.6 million of a mixed heavy rare earth product it calls SEG+ to a US aerospace and defence customer. That buyer signed a long-term gadolinium contract in July. Rosenthal cautioned that "we do not believe today's elevated prices will persist indefinitely".
What to watch: the first finished terbium and dysprosium, due in the fourth-quarter report. The early output goes to MP's own magnet plant, Corbett said, so it will not appear as revenue.
🐻 Bear Case
Without the One-Off Sale, Income Stood Still
Litinsky described "a strong quarter of growth across production, sales, and earnings". The headline agrees: revenue rose 176% from a year ago, a quarter when MP had just stopped selling to China. But $31.6 million of it came from one sale of stockpiled material, "a bit of a one-off to support a strategic customer", Corbett said.
Strip out that sale and the picture changes. The Department of War pays MP the gap between $110 a kilogram and a market benchmark. That payment shrinks as market prices rise. After the midterms Litinsky said "we really see no change" to that contract.
- Revenue plus floor income, excluding the sale: $124 million, down 1.5% from last quarter by our math
- Floor payment per kilogram sold: about $8, from about $17 last quarter by our math
- MP's price plus floor payment: about $107 a kilogram, below the $110 floor, because the floor tracks a benchmark, not MP's price
What to watch: fourth-quarter NdPr revenue plus floor income, against $109 million this quarter. Corbett plans "approximately 1,000 metric tons and $100 per kilogram", which gives the same figure by our math.
Magnet Profits Stay Small Until 2028
The magnet division still lives on a prepayment. GM paid $150 million in advance for NdPr metal, and MP books it as revenue as it delivers. Only $27.6 million remains, so Corbett expects it to run off "at a declining rate".
Magnets will not replace it quickly. Corbett said the division's profit will stay modest through 2027, and expects "the full earnings power of the segment to become visible in 2028". The squeeze shows: the division's margin fell to 29% from 46% last quarter, because costs once charged to metal now sit with the first magnets.
What to watch: Magnetics revenue in the fourth quarter, when the first magnet sales join shrinking metal revenue. A total below this quarter's $18.6 million would mean magnets are not yet covering the run-off.
Building Costs Outrun Cash While Notes Become Convertible
MP spent $113 million on plants and equipment in the quarter, while operations used $13 million of cash by our math. Free cash flow was therefore about minus $125 million. Cash and investments fell to $1.34 billion from $1.45 billion in June. Corbett held the full-year building budget at "$500 million-$600 million".
The balance sheet can carry that for now. But holders of MP's $863 million of convertible notes may now swap them for shares. The notes passed their conversion test in the quarter, the filing says. Full conversion would add about 40 million shares to 178 million by our math.
What to watch: the diluted share count in the fourth-quarter report, and whether MP pays cash or issues shares for any notes converted.
Risks this quarter didn't answer
Four standing concerns got words from management but no numbers, so none of them moved. Each needs one disclosure to settle it.
- NdPr cost per kilogram: no figure again; Corbett expects lower costs in the second half of 2027, once new plants settle.
- Magnet prices and margins: not disclosed; Corbett declined to give volumes "given the nature of our customer contracts".
- 10X economics: Litinsky said customer requests "well exceed the 10X capacity", but gave no price or margin for the plant's output.
- Customer concentration: four customers made 89% of revenue by our math, and the new one at 21% bought the one-off SEG+ product.
👓 Other Themes
China's Export Curbs Keep Rare Earth Prices High
China restricted exports of rare earths through 2025 and, MP's filing says, agreed in November 2025 to suspend the expanded controls. Shortages and high prices for the heavier rare earths have continued since. The filing calls these trends ones that "may or may not be permanent". Litinsky pointed to a presidential proclamation on robotics and new FCC limits on foreign-made robots as reasons US buyers will want domestic magnets.
💲 Other KPIs
Rising for a third quarter. MP recognised 56% of revenue while the goods stayed in its own or a warehouse's custody, against 47% in the second quarter. A year ago the share was 41%. Without the one-off sale, itself a bill-and-hold deal, the share was 44% by our math. The practice is allowed when the customer owns goods set aside for it.
Overhead keeps shrinking against revenue. Selling, general and administrative costs took 25.7% of revenue, down from 53.0% a year ago. The share was 32.4% in the second quarter. The dollar amount still rose 34% because MP added staff. Start-up costs for the magnet and chlor-alkali plants took another 9.6% of revenue, and Corbett expects them to continue through the first half of 2027.
Down $6 million in the quarter to $120 million, the third decline in a row. Deferred revenue is cash customers paid for goods not yet delivered. The balance mixes GM's remaining metal prepayment, which MP works down as it delivers, with $80 million from Apple. MP cannot book the Apple money until magnets ship to Apple from late 2027. Apple paid another $8 million in the quarter.
🔮 Guidance
New. Corbett expects to sell about 1,000 tons of NdPr in the fourth quarter, level with the 1,020 tons sold this quarter. Production took a planned maintenance stop of 10 to 14 days in October, so sales will depend on finished stock. Rosenthal expects fourth-quarter production to keep growing at a similar pace from a year ago.
New. Corbett expects a selling price of about $100 a kilogram, with a floor payment of about $8 on top. The sum stays below the $110 floor for a second quarter, because the payment tracks a market benchmark rather than MP's own price. On 1,000 tons that gives about $108 million of NdPr income, level with this quarter by our math.
Unchanged. MP has spent $414 million in nine months on the filing's measure, net of government grants. The range therefore leaves $86 million to $186 million for the fourth quarter by our math. That is more than the $106 million spent in the third. About 60% of the year's spending so far went to magnets, mainly the 10X plant and its land in Texas, Corbett said.
Unchanged. GM has finished qualifying the magnets, and Corbett expects saleable deliveries and the first magnet revenue in the fourth quarter. Volumes start small, he said, and magnet sales are "likely to be lumpy quarter-to-quarter". GM phases MP's magnets into specific programmes and plants over time.
Unchanged. Litinsky said commercial-scale production of the two heavy rare earths starts this quarter, in line with the timing given in August. Rosenthal said the first circuits are running as planned. The output goes first to MP's own magnet plant, so Corbett expects no outside revenue from it for a while.
New. Rosenthal expects Mountain Pass to produce at a rate above 5,000 tons across 2027. That is about 1,250 tons a quarter by our math, against 1,018 this quarter. The plan already includes extra downtime in the first quarter for the start of the chlor-alkali plant, which makes the refinery's own chemicals. Recycling and heavy rare earth projects add more.
New. Corbett expects magnet sales to earn a profit from the first delivery. But the segment's total will "continue to be modest in 2027, particularly in the first half", because shrinking metal revenue offsets the early magnet sales. Start-up costs continue "for at least the first half of next year". He expects "the full earnings power of the segment to become visible in 2028".
❓ Key Questions
What did the SEG+ sale cost, and what did it earn?
Corbett declined to give the cost. The stockpile built up as a by-product of NdPr separation. The margin on this $31.6 million sale decides how much of the quarter's profit was repeatable.
Why is price plus floor payment below $110?
The floor pays the gap between $110 and a market benchmark, yet MP's own price plus payment came to about $107 by our math. Readers need the benchmark and MP's discount to it.
What does a kilogram of NdPr cost to make today?
The $40 target has no date and, for another quarter, no progress figure. Corbett pointed to the second half of 2027 for lower unit costs, which leaves the 2026 level unknown.
How many magnets, at what price, will GM take in 2027?
Corbett gave no volumes or prices and declined again to say when Independence reaches 1,000 tons a year. The magnet ramp is the whole 2027 story and has no numbers.
Will MP settle note conversions in cash or shares?
Holders of $863 million of notes may convert this quarter. MP may pay cash, shares or both, and the choice decides whether the share count rises by up to 40 million.
