A rare earth miner building a defense-backed U.S. supply chain
- MP owns Mountain Pass, the only rare earth mining and processing site of scale in North America.
- The business changed in July 2025 when MP stopped selling to China and tied its future to U.S. supply chains.
- A new 9-figure aerospace agreement for gadolinium shows MP is expanding beyond its core NdPr products.
- The Magnetics segment delivered test magnets to General Motors and plans to start commercial shipments in late 2026.
- The strategy is stronger now, but the stock still depends on flawless execution and long-lasting government support.
Washington changed the story
MP used to be a rare earth miner with heavy exposure to China and spot market prices. That changed in 2025. The company stopped sales to China and built its new model around the U.S. Department of Defense, General Motors, Apple, and other U.S. customers that want a domestic magnet supply chain.
The bull case is getting stronger. MP has a working separation business and a magnet plant that is ramping up. It recently signed a 9-figure deal to supply gadolinium for aerospace and started Project Swarm to coordinate drone magnet demand. Its Texas 10X facility has also started vertical construction.
The bear case is also clearer. MP is now dependent on government contracts, federal budgets, and its own ability to build large factories on time. It must flawlessly execute the ramp of the Independence facility to maximum capacity and manage massive construction costs. Investors still have to ask how much of the good news is already priced into the stock.
From China sales to a defense-backed chain
MP makes money in two steps. First, the Materials segment mines rare earth ore at Mountain Pass and turns it into rare earth concentrate and separated products such as NdPr oxide and NdPr metal.
Second, the Magnetics segment turns rare earth materials into magnetic precursor products and finished NdFeB permanent magnets. These magnets are used in electric motors, electronics, and defense systems. Soon, MP plans to stop selling precursor products to outsiders and use them all to make finished magnets internally.
The Department of Defense agreements now sit at the center of the model. The NdPr price floor is $110 per kilogram. The DoD also agreed to buy the full output of the planned 10X magnet facility for 10 years, offering guaranteed minimum annual EBITDA once it reaches full capacity.
This lowers commodity risk, but it creates a new kind of risk. MP is less tied to spot rare earth prices and Chinese buyers. It is more tied to U.S. policy, DoD funding, contract rules, and the delivery of large industrial projects.
The products moving downstream
Rare earth concentrate
This was MP's legacy product. After July 2025, MP ceased all product sales to China, so concentrate sales are now far less central to the story.
NdPr oxide
NdPr oxide is a separated rare earth product made from Mountain Pass output. It is now protected by the DoD price floor when market prices fall below $110 per kilogram.
Heavy rare earths
MP is expanding into products like gadolinium oxide, backed by a large aerospace contract, with dysprosium and terbium expected to follow.
Magnetic precursor products
These are used before finished magnets are made. MP plans to stop selling these externally and use them to feed its own finished magnet production.
Finished NdFeB permanent magnets
MP manufactures finished sintered NdFeB permanent magnets at the Independence Facility. It has delivered test magnets to GM and expects commercial shipments in late 2026.
10X facility magnets
The planned 10X facility in Texas is meant to greatly expand U.S. magnet capacity. Its full output is committed to the DoD under a 10-year offtake agreement.
Two segments, one transition
Segment mix is based on Q1 2026 segment revenue. The mix is shifting quickly as MP stops external precursor sales and ramps finished magnet output for U.S. customers.
What could break the thesis
DoD support changes
High impact · Medium oddsMP's new model depends on the DoD price floor, offtake agreement, and funding. The company itself warns that continued support for the DoD transactions could be modified, challenged, or impaired. A change in federal priorities or appropriations could hurt cash flow and investor confidence.
10X construction slips or costs rise
High impact · Medium oddsThe 10X facility is a large industrial project, not a simple capacity add. MP has started vertical construction, but equipment, staffing, and qualification still have to happen. Delays could push out the guaranteed EBITDA benefits tied to full capacity.
Independence magnet ramp disappoints
High impact · Medium oddsThe Magnetics segment is growing fast, but it is still in a ramp phase. MP must make magnets at the right quality, volume, and cost for customers such as GM and Apple. If the plant fails to scale, the vertical integration story weakens.
Contract limits reduce flexibility
Medium impact · Medium oddsThe DoD agreements include covenants that restrict some strategic actions. These can limit asset sales, product sales to restricted buyers, and certain deals. That can be good for national security, but it may reduce MP's choices if markets change.
In one breath
What does MP Materials actually do?
MP mines rare earths at Mountain Pass in California, separates key rare earth products, and is building a U.S. magnet business. Its goal is to supply rare earth materials and magnets without relying on China.
Why is the Department of Defense important to MP?
The DoD gives MP a price floor for NdPr products and agreed to buy the full output of the planned 10X magnet facility for 10 years. This makes MP less exposed to commodity price swings, but more exposed to government policy and funding.
Is MP Materials profitable now?
Q1 2026 showed much better segment profitability because the DoD price protection payment was large. Materials Segment Adjusted EBITDA was $36.7 million, and Magnetics Segment Adjusted EBITDA was $9.6 million, but investors still need to watch full-company profitability, cash flow, and project spending.
What are the next big milestones for MP?
The key items are commercial finished magnet shipments to GM in late 2026, heavy rare earth shipments from Mountain Pass, and progress on the 10X facility construction in Texas.
