MP Materials owns a rare earths mine and processing facility near the California-Nevada border on the edges of the Mojave National Preserve. It claims to be “the largest producer of rare earth materials in the Western Hemisphere,” with “the only rare earth mining and processing site of scale in North America.”
As part of the deal, the company will build a “10X Facility” to produce magnets, which the DOD has guaranteed will be able to sell 100% of its output to some combination of the Pentagon and commercial customers. The DOD is also kicking in $150 million worth of financing for MP Materials’ existing processing efforts in California, alongside $1 billion from Wall Street — specifically JPMorgan Chase and Goldman Sachs — for the new magnet facility. The company described the deal in total as “a multi-billion-dollar commitment to accelerate American rare earth supply chain independence.”
Finally, the DOD will buy $400 million worth of newly issued stock in MP Materials, giving it a stake in the future production that it’s also underwriting.
Between the equity investment, the lending, and the guaranteed purchasing, the Pentagon, and by extension the federal government, has taken on considerable financial risk in casting its lot with a company whose primary asset’s previous owner went bankrupt a decade ago. But at least so far, Wall Street is happy with the deal: MP Materials’ market capitalization soared to over $7 billion on Thursday after its share price jumped over 40%, from a market capitalization of around $5 billion on Wednesday and the company is valued at around $7.5 billion as of Friday afternoon.
Despite the risk, former Biden administration officials told me they would have loved to make a deal like this.
When I asked Alex Jacquez, who worked on industrial policy for the National Economic Council in the Biden White House, whether he wished he could’ve overseen something like the DOD deal with MP Materials, he replied, “100%.” I put the same question to Ashley Zumwalt-Forbes, a former Department of Energy official who is now an investor; she said, “Absolutely.”
Rare earths and critical minerals were of intense interest to the Biden administration because of their use in renewable energy and energy storage. Magnets made with neodymium-praseodymium oxide are used in the electric motors found in EVs and wind turbines, as well as for various applications in the defense industry.
MP Materials will likely have to continue to rely on both sets of customers. Building up a real domestic market for the China-dominated industry will likely require both sets of buyers. According to a Commerce Department report issued in 2022, “despite their importance to national security, defense demand for … magnets is only a small portion of overall demand and insufficient to support an economically viable domestic industry.”
The Biden administration previously awarded MP Materials $58.5 million in 2024 through the Inflation Reduction Act’s 48C Advanced Energy Project tax credit to support the construction of a magnet facility in Fort Worth. While the deal did not come with the price guarantees and advanced commitment to purchase the facility’s output of the new agreement, GM agreed to come on as an initial buyer.
Matt Sloustcher, an MP Materials spokesperson, confirmed to me that the Texas magnet facility is on track to be fully up and running by the end of this year, and that other electric vehicle manufacturers could be customers of the new facility announced on Thursday.
At the time MP Materials received that tax credit award, the federal government was putting immense resources behind electric vehicles, which bolstered the overall supply supply chain and specifically demand for components like magnets. That support is now being slashed, however, thanks to the One Big Beautiful Bill Act, which will cancel consumer-side subsidies for electric vehicle purchases.
While the Biden tax credit deal and the DOD investment have different emphases, they both follow on years of bipartisan support for MP Materials. In 2020, the DOD used its authority under the Defense Production Act to award almost $10 million to MP Materials to support its investments in mineral refining. At the time, the company had been ailing in part due to retaliatory tariffs from China, cutting off the main market for its rare earths. The company was shipping its mined product to China to be refined, processed, and then used as a component in manufacturing.
“Currently, the Company sells the vast majority of its rare earth concentrate to Shenghe Resources,” MP Materials the company said in its 2024 annual report, referring to a Chinese rare earths company.
The Biden administration continued and deepened the federal government’s relationship with MP Materials, this time complementing the defense investments with climate-related projects. In 2022, the DOD awarded a contract worth $35 million to MP Materials for its processing project in order to “enable integration of [heavy rare earth elements] products into DoD and civilian applications, ensuring downstream [heavy rare earth elements] industries have access to a reliable feedstock supplier.”
While the DOD deal does not mean MP Materials is abandoning its energy customers or focus, the company does appear to be to the new political environment. In its February earnings release, the company mentioned “automaker” or “automotive-grade magnets” four times; in its May earnings release, that fell to zero times.
Former Biden administration officials who worked on critical minerals and energy policy are still impressed.
The deal is “a big win for the U.S. rare earths supply chain and an extremely sophisticated public-private structure giving not just capital, but strategic certainty. All the right levers are here: equity, debt, price floor, and offtake. A full-stack solution to scale a startup facility against a monopoly,” Zumwalt-Forbes, the former Department of Energy official, wrote on LinkedIn.
While the U.S. has plentiful access to rare earths in the ground, Zumwalt-Forbes told me, it has “a very underdeveloped ability to take that concentrate away from mine sites and make useful materials out of them. What this deal does is it effectively bridges that gap.”
The issue with developing that “midstream” industry, Jacquez told me, is that China’s world-leading mining, processing, and refining capacity allows it to essentially crash the price of rare earths to see off foreign competitors and make future investment in non-Chinese mining or processing unprofitable. While rare earths are valuable strategically, China’s whip hand over the market makes them less financially valuable and deters investment.
“When they see a threat — and MP is a good example — they start ramping up production,” he said. Jacquez pointed to neodymium prices spiking in early 2022, right around when the Pentagon threw itself behind MP Materials’ processing efforts. At almost exactly the same time, several state-owned Chinese rare earth companies merged. Neodymium-praseodymium oxide prices fell throughout 2022 thanks to higher Chinese production quotas — and continued to fall for several years.
While the U.S. has plentiful access to rare earths in the ground, Zumwalt-Forbes told me, it has “a very underdeveloped ability to take that concentrate out away from mine sites and make useful materials out of them. What this deal does is it effectively bridges that gap.”
The combination of whipsawing prices and monopolistic Chinese capacity to process and refine rare earths makes the U.S.’s existing large rare earth reserves less commercially viable.
“In order to compete against that monopoly, the government needed to be fairly heavy handed in structuring a deal that would both get a magnet facility up and running and ensure that that magnet facility stays in operation and weathers the storm of Chinese price manipulation,” Zumwalt-Forbes said.
Beyond simply throwing money around, the federal government can also make long-term commitments that private companies and investors may not be willing or able to make.
“What this Department of Defense deal did is, yes, it provided much-needed cash. But it also gave them strategic certainty around getting that facility off the ground, which is almost more important,” Zumwalt-Forbes said.
“I think this won’t be the last creative critical mineral deal that we see coming out of the Department of Defense,” Zumwalt-Forbes added. They certainly are in pole position here, as opposed to the other agencies and prior administrations.”
