5E Advanced shares surge 13.19% after-hours as company targets domestic ferroboron production to bolster U.S. supply chains.

5E Advanced Materials (FEAM) surged 13.19% in after-hours trading following its announcement to develop domestic ferroboron production using boric acid from its Fort Cady site. The move aims to address the U.S.’s reliance on imported ferroboron, a critical material for specialty steel and neodymium-iron-boron (NdFeB) magnets used in electric motors, wind turbines, and defense systems. The company highlighted supply chain risks tied to Chinese manufacturing and emphasized its strategic alignment with U.S. decarbonization and energy security goals. CEO Paul Weibel noted the initiative strengthens 5E’s vertical integration and positions it to capitalize on growing demand for secure domestic materials. The news reinforced investor optimism about the firm’s pivot to higher-value boron derivatives amid geopolitical tensions and policy tailwinds.
