MP Materials Corp. reported stronger top-line activity in the first half of 2025, with revenue rising to $118.2 million for the six months ended June 30, 2025 from $79.9 million a year earlier, driven by higher NdPr oxide/metal sales and the start of magnetic precursor product shipments from its Independence Facility.
