What USA Rare Earth, Inc. told the SEC could break it.
USA Rare Earth's disclosures revolve around the same fact from two directions: China controls roughly 99% of global heavy-rare-earth processing and refined gallium, the midstream bottleneck its magnet ambitions aim to break, and during 2025 China expanded export controls requiring licenses even for products containing small amounts of Chinese-origin rare earths. That dominance shapes its own supply risk — if its Round Top project isn't completed and commercial, it would be wholly reliant on third-party feedstock for neodymium magnet production. As an early-stage producer in its first revenue year ($1.6M in 2025), it is also highly customer-concentrated, with one buyer at 73% and a second at 18% of revenue.
4 self-disclosed vulnerabilities, pulled from its own filings, each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Commodity & input dependence
- China controls ~99% of HREE processing and rare earth midstreamhigh
China controls roughly 99% of global heavy-rare-earth (HREE) processing and ~99% of refined gallium, with near-total dependence on Chinese separation, metal-making and magnet-alloy capacity — a critical midstream bottleneck (especially HREE and samarium alloys) for non-China magnet manufacturing.
“China controls ~99% of global HREE processing, leaving the U.S. and its allies highly exposed.”
Customer concentration
- Customer 1 = 73%, Customer 2 = 18% of 2025 revenuemedium
In its first revenue year (2025 revenue of $1.6M), one customer accounted for 73% and a second for 18% of revenue (both unnamed); the company notes the concentration shifts with shipment timing.
“Customer 1 73 % Customer 2 18 % All other customers 9 %”

Supplier concentration
- Reliance on third-party feedstock for neo production if Round Top not completedmedium
If the Round Top Project is not completed and commercial, USA Rare Earth would be wholly reliant on third-party sources for rare earth feedstock for its neo (NdPr) magnet production, exposing it to cost and availability volatility.
“If the Round Top Project is not completed, operative, and commercial, we will be wholly reliant on third-party sources for feedstock for neo production which could be costly and damaging to our results of operations.”
Regulatory & policy
- China 2025 export controls/licensing on rare earthslow
During 2025 China imposed and expanded export controls on certain rare earths and related materials, requiring special export licenses and Chinese government approval for exports of products containing even small amounts of Chinese-origin rare earths.
“In addition, during 2025, China imposed and expanded export controls and restrictions on certain rare earths and related materials, requiring companies to secure special export licenses and obtain Chinese government approval for exports of products containing even small amounts of Chinese-origin rare earths, among other restrictions.”
