Shares of MP Materials Corp. and Evolution Metals & Technologies Corp. rose Friday afternoon as investors responded to Trump administration trade and defense actions seen as supportive for U.S. rare earth and critical minerals supply chains. Benzinga Pro data cited MP Materials up 6.27% at $59.15 and Evolution Metals up 39.38% at $3.15, with the policy package described as including tariffs on foreign-made drones and components, a newer account specifying a 100% ad valorem tariff on heavy foreign-made drones and thermal components, expanded interceptor missile production agreements with Boeing and RTX, and domestic supply chain directives for defense contractors. Investors focused on MP Materials' Mountain Pass operation, described as the sole active rare earth mining and processing site in the United States, and on Evolution Metals, described as a primary U.S. producer of rare earth permanent magnets including sintered neodymium-iron-boron used in drone and defense motors, with additional momentum from its board appointment of retired U.S. Air Force General Thomas A. Bussiere and its planned expansion toward 10,000 metric tons of annual magnet capacity ahead of 2027 Department of Defense sourcing restrictions.
