This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.
MP Materials Corp owns and operates the Mountain Pass mine in California, the only active rare earth mining and processing site in the United States. The company extracts and refines rare earth oxides and metals, which are critical materials for permanent magnets used in electric vehicles, wind turbines, and defense systems. Its business is fundamentally that of a non-fuel mineral extractor.
The company has faced securities litigation alleging misleading statements and omissions related to its business combination and operations. A class action complaint filed in February 2022 alleges violations of federal securities laws, though the specific outcomes or settlements from this litigation are not detailed in the provided evidence. This pattern of regulatory and legal challenges is a noted risk factor for investors.
MP Materials Corp. operates the Mountain Pass rare earth element mine in California, a site with a documented history of environmental contamination. The facility was previously an EPA Superfund site due to legacy radioactive and heavy metal contamination from prior operations. While the current operator emphasizes modern environmental management plans, the extraction and processing of rare earths inherently generates significant volumes of low-level radioactive thorium and uranium waste, along with risks of water contamination from chemical processing.
A 2022 federal securities class action complaint alleged the company made materially false and misleading statements regarding, among other things, its environmental compliance and the associated regulatory risks. The complaint specifically cited the company's failure to disclose the full extent of environmental liabilities and the risk that permits required for its expansion plans might not be granted.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.
