Rare-earth producer MP Materials has signed a multi-year agreement to supply gadolinium oxide to an unnamed major U.S. aerospace and defense manufacturer, deepening its role as the country's anchor domestic rare-earth supplier for critical applications. The contract is expected to be worth nine figures over multiple years, with MP developing additional heavy rare-earth separation capacity at its Mountain Pass, California operations.
Why Gadolinium Matters
Gadolinium is one of the 17 rare-earth metals and is used in nuclear reactor shielding on U.S. Navy submarines, infrared sensors, magnetic-resonance imaging contrast agents and high-temperature electronics. Adding it to MP's mix expands the company's heavy rare-earth element (HREE) product portfolio beyond the neodymium-praseodymium (NdPr) oxide that has been its cornerstone product. The customer's identity was not disclosed.
Building A Defense-Anchored Revenue Stack
The gadolinium contract lands on top of MP's public-private partnership with the U.S. Department of Defense around the 10X magnet facility, which established a price floor for NdPr and secured a 10-year magnet purchase commitment. Together, the two arrangements make government-backed demand a bigger and more concentrated slice of MP's revenue mix, supportive for the investment case but also concentrating counterparty risk in a small group of anchor buyers.
Fits A U.S. Reshoring Push
The Pentagon has spent 2026 quietly rebuilding a domestic rare-earth and critical-minerals stack after years of Chinese dominance in refining and magnet production. MP is the only fully integrated U.S. rare-earth producer, running Mountain Pass — home to one of the world's richest deposits — plus the Independence magnet plant in Texas. The new HREE separation capacity slated for Mountain Pass will require capital investment but also gives MP a defensible foothold in a category historically monopolized by Chinese suppliers. The move also aligns with the broader defense-industrial theme visible in recent Pentagon drone-detection awards and Silicon Valley's push into hardware.
What To Watch Next
Analysts covering MP flagged that customer concentration remains a key risk even as the defense contracts add revenue visibility. The company has projected a path toward $1.1 billion in revenue and $270 million in earnings by 2029, a trajectory that will require successful ramp of both the 10X magnet facility and the new HREE separation capacity. Investors should watch for named customer disclosures, ramp milestones at Mountain Pass and Independence, and any follow-on defense supply agreements this quarter.
