Rhea-AI Summary

MP Materials reported strong second-quarter 2026 growth while remaining loss-making. Revenue for the three months ended June 30, 2026 rose 89% year over year to $108.5 million, driven by higher sales of NdPr oxide and metal and stronger pricing, with additional $17.6 million of price protection agreement income. NdPr production reached 840 metric tons, up 41%, and NdPr sales volume was 1,006 metric tons, up 127%.

Adjusted EBITDA improved to $28.5 million from a loss of $12.5 million, and Adjusted Net Loss narrowed to $2.1 million, aided by higher revenues and PPA income, partly offset by higher costs and SG&A. GAAP net loss improved to $20.3 million from $30.9 million, with diluted loss per share at $(0.11). The Materials segment more than doubled revenue to $95.6 million and generated $32.5 million of Segment Adjusted EBITDA, while the Magnetics segment delivered $16.5 million of revenue and $7.5 million of Segment Adjusted EBITDA. Strategically, MP Materials signed a significant long-term offtake agreement with a new American aerospace and defense customer for separated gadolinium and launched Project Swarm to aggregate demand and standardize magnet specifications for the drone industry.
