MP Materials stock news
MP Materials (NYSE: MP) shares surged 9.19% on August 21, 2026, closing at $60.05 following the announcement of a new long--term gadolinium supply agreement with a major U.S. aerospace and defense customer. The rally was further supported by heightened market optimism regarding the company's dominance in the domestic rare earth supply chain. Operationally, MP Materials is ramping up Neodymium--Praseodymium (NdPr) production and accelerating the development of its "10X" magnet facility in Texas. Despite the positive momentum, some analysts have issued a "Sell" rating, suggesting that the current valuation already reflects an overly optimistic execution of the company's downstream expansion.
