USA Rare Earth–Arnold Magnetic deal: supply-chain and capex lens for mine planners
Reviewed by Joe Ashwell

30 Second Briefing
USA Rare Earth has signed a non-exclusive mutual sales and distribution deal with Arnold Magnetic Technologies, linking USAR’s processed and refined neodymium-iron-boron (NdFeB) feedstock and mine-to-magnet pipeline with Arnold’s samarium-cobalt (SmCo) and NdFeB permanent magnet manufacturing. The partnership is anchored by USAR’s planned Round Top rare earths deposit in Texas (targeting production in late 2028) and a Stillwater, Oklahoma magnet plant designed for 5,000 tonnes per year, due online this year. Both firms aim to supply “compliance-ready” magnets for aerospace, defence, semiconductor and EV applications within a US-aligned supply chain.
Technical Brief
- Mutual sales agreement is explicitly non-exclusive, allowing both parties to engage additional suppliers and customers.
- USA Rare Earth will distribute Arnold’s finished SmCo and NdFeB permanent magnets alongside its own products.
- Arnold will market USA Rare Earth’s processed and refined NdFeB feedstock as well as finished magnets.
- Each company retains full responsibility for product quality warranties and any product-related liabilities on its own output.
- Arnold Magnetic Technologies operates under Compass Diversified ownership, adding private equity backing to the supply chain.
- USA Rare Earth is currently valued at about $3.8 billion market capitalisation on Nasdaq.
- Collaboration specifically targets high-volume demand plus bespoke, mission-specific magnet solutions for critical end-users.
Our Take
USA Rare Earth’s mutual sales deal around samarium–cobalt and neodymium–iron–boron magnets slots into a wider build‑out of its downstream footprint, which in our database already includes the planned Lacq, France metals and alloys plant and the Round Top heavy rare earths project in Texas.
The agreement with Arnold Magnetic Technologies strengthens the US‑based rare earths value chain at the same time as USA Rare Earth is securing substantial public support under the CHIPS programme, signalling that policymakers want domestic offtake channels for critical magnets to keep pace with upstream and processing investments.
Oklahoma’s push to become a critical minerals processing hub, highlighted in recent coverage of Emirates Global Aluminium’s proposed smelter, gives USA Rare Earth and Arnold a potential logistics and customer base bridge between Round Top in Texas and US manufacturing centres needing rare earth magnet products by the late‑2028 horizon.
