MP Materials Corp. (NYSE: MP) experienced a significant surge of 5.09% in the after-hours session on Thursday, following the release of its first-quarter 2026 financial results that exceeded analyst expectations across key metrics.

The rare earth producer reported adjusted earnings per share of $0.03 for the quarter, swinging from a loss of $0.12 a year earlier and beating the consensus estimate of breakeven results. Revenue jumped 49% year-over-year to $90.6 million, surpassing analyst forecasts of approximately $76.5 million. The strong performance was driven by record NdPr production of 917 metric tons (a 63% increase) and record NdPr sales of 1,006 metric tons (a 117% increase), along with higher market pricing for rare earth materials.

Concurrently, the company announced it broke ground on its 10X magnetics facility in Texas and expects to begin commissioning its heavy rare earths separation circuit in the second quarter. These strategic developments, combined with price protection agreement income from the U.S. government and growing sales in its magnetics segment, contributed to the positive investor sentiment driving the stock's after-hours gains.
