In its Q2 2025 results, MP Materials reported an 84 percent year-over-year increase in revenue, which totaled US$57.4 million in Q2. Additionally, the company achieved record NdPr output of 597 metric tons (MT), while its rare earth oxide (REO) production reached 13,145 MT, marking its second-highest quarterly production ever and a 45 percent increase from last year.

In early July, MP penned a deal with the US DoD in which the government would purchase US$400 million worth of preferred stock in the company, making the DoD the company’s largest shareholder.

The funds are earmarked for the expansion of its processing capabilities at Mountain Pass and the construction of a second magnet manufacturing facility in the US.

MP also signed a US$500 million deal with Apple (NASDAQ:AAPL) to produce rare earth magnets in the US using only recycled materials. Starting in 2027, MP will supply magnets for hundreds of millions of Apple devices, including iPhones, iPads and MacBooks.

2. Energy Fuels (NYSEAMERICAN:UUUU,TSX:EFR)

Market cap: US$1.97 billion
Share price: US$8.53

Energy Fuels is a leading US uranium and rare earths company that operates key uranium production centers, including the White Mesa mill in Utah and the Nichols Ranch and Alta Mesa projects in Wyoming and Texas.

The company finished construction of Phase 1 REE separation infrastructure at White Mesa in early 2024, and in June reported successful commercial production of separated NdPr that meets the specifications required for REE-based alloy manufacturing. The Phase 1 REE separation circuit is now operating at full capacity.

Following its 2023 acquisition of the Bahia heavy mineral sands project in Brazil, Energy Fuels made multiple deals in 2024 with the aim of acquiring feedstock for White Mesa.

In early June of last year, Energy Fuels executed a joint venture that gives it the option to earn a 49 percent stake in Astron’s (ASX:ATR) Donald rare earths and mineral sands project in Victoria, Australia. Donald is expected to begin production as early as 2026, and will supply the White Mesa mill with 7,000 to 8,000 MT of monazite sand in rare earths concentrate annually in Phase 1.

In October 2024, Energy Fuels acquired Australian mineral sands company Base Resources, which owns the Toliara project in Madagascar.

As for 2025, in mid-March Energy Fuels inked a memorandum of understanding with South Korea-based POSCO Holdings (NYSE:PKX,KRX:005490) for the potential creation of a non-China REE supply chain for EVs and hybrid EV drivetrains for US, EU, Japanese and South Korean auto markets.

In June 2025, the Government of Victoria approved the work plan for the construction and operation of the Donald rare earth and mineral sand project. The site can now move into construction.

A month later, Energy Fuels achieved pilot-scale production of heavy rare earth oxides at its White Mesa mill and aims for commercial output by late 2026. Additionally, the company noted that it could source feedstock from the Donald project by the end of 2027.

In late August, Energy Fuels successfully produced its first kilogram of 99.9 percent pure dysprosium oxide at pilot scale from White Mesa. Using monazite sourced from Florida and Georgia, Energy Fuels now plans to produce 2 kilograms weekly.

“Multiple magnet manufacturers and OEMs have already expressed their strong interest in obtaining these samples to accelerate their validation processes,” the company said.
