MP Materials Powers Up US Rare Earths Supply
23 Sep
Summary
- MP Materials nearing full production of rare earth oxide.
- First commercial magnet deliveries to General Motors by year-end.
- Company's adjusted EBITDA turned positive year-over-year.

MP Materials Corp. is making significant strides in establishing a domestic rare earth supply chain, moving beyond a policy initiative to a tangible business. The company's Mountain Pass facility in California is approaching full run-rate production of neodymium-praseodymium oxide. This increased output is crucial for reducing U.S. reliance on Chinese-processed rare earths.
Recent performance indicates strong growth, with second-quarter sales volumes exceeding 1,000 tons for two consecutive quarters, representing a 127% year-over-year increase. Furthermore, the company achieved a positive adjusted EBITDA of $28.5 million, a substantial improvement from a $12.5 million loss in the prior year's second quarter.
In parallel, MP Materials is solidifying its relationship with General Motors. While magnets have been delivered for qualification and testing, commercial shipments are slated to commence in the fourth quarter of 2026. This follows a long-term supply agreement initiated in April 2022, demonstrating a significant forward-looking commitment.
The company's progress is underpinned by key operational achievements, including surpassing 1,000 tons in sales for two straight quarters and achieving positive adjusted EBITDA. These tangible production numbers support the narrative that MP Materials is successfully scaling its rare earth magnet production capabilities.
