Narrative

USA Rare Earth announced LCM Europe SAS on 20 January 2026 as a new subsidiary that will build a rare-earth metal and complex-alloy plant at Lacq, France, with French government support under the C3IV program: credits for up to 45% of eligible equipment costs, plus up to EUR 130 million toward real estate. The project is planned for roughly 3,750 metric tons per year of capacity across light and heavy rare earth metals and complex alloy systems, at an estimated total cost of EUR 110 million and 100 to 140 jobs. It sits on the same site as, but is a legally separate facility from, Carester's Caremag plant, which processes rare earth oxides and is separately on track for late-2026 commissioning. As of September 2026, no construction start, groundbreaking, or commissioning date has been published for LCM Europe itself. LCM Europe should not be confused with Less Common Metals Ltd., USA Rare Earth's existing UK subsidiary in Ellesmere Port, which already operates a rare earth metal and alloy plant.

How this page is sourced

Everything here comes from public sources — company filings, annual reports, exchange announcements, government releases and trade press. Every figure is linked to the document it came from and carries the date that document was published, because a capacity number without a date is not a fact, it is a rumor with a decimal point.

What is deliberately absent: material nonpublic information. I have spent more than two decades in this industry and a good deal of what I know about these companies I learned under NDA. Those obligations do not expire and they do not bend for a website. Nothing I have been told in confidence appears here in any form, and nothing on this page — or missing from it — should be read as a signal about what I know privately. I hold NDAs absolutely. It is the reason clients tell me things.

Judgment is the other thing left out on purpose. This page reports what has been published and who published it. Whether a target is credible, whether a ramp will hold, whether a capacity figure survives contact with the plant behind it — that is the work I do for clients, and it does not belong in a free reference page.

Where public sources disagree, I say so rather than picking a winner. Where a figure has not been published, the field says so rather than carrying an estimate. An empty field is information too.

Public filings tell you what a company has said. Whether it holds up is a different question, and the one I get hired to answer.
