5E Seeks to Collaborate with U.S. Magnet Producer to Solve Ferroboron Supply Gap

U.S. Supply Chains for Ferroboron are Import-Reliant with Significant Supply Chain Risk Tied to Chinese Manufacturing

HESPERIA, CALIFORNIA / ACCESS Newswire / February 4, 2026 / 5E Advanced Materials, Inc. ("5E" or the "Company") (Nasdaq:FEAM)(ASX:5EA), a company focused on becoming a vertically integrated global leader and supplier of refined borates and advanced boron derivative materials, today announced that it targets future production of Ferroboron and the establishment of a secure, domestic supply chain utilizing upstream feedstock of boric acid produced from its Fort Cady site in California. Ferroboron is an iron-boron alloy used as a boron additive in specialty steel and as a boron source for neodymium-iron-boron (NdFeB) magnet alloy feedstock. NdFeB permanent magnets are essential components in high-efficiency electric motors, wind turbines, industrial automation and defense systems. Recent export controls and geopolitical friction have reinforced investors' and customers' focus on domestic magnet supply chains, where global manufacturing remains highly concentrated. The U.S. currently has no domestic production of ferroboron, creating a critical dependency within specialty steel and permanent magnet supply chains.

Key Takeaways:

• Advances 5E towards realizing its longer-term mission of providing higher value boron derivatives

• Targets a higher-value boron derivative (ferroboron), leveraging Fort Cady boric acid as upstream feedstock.

• Addresses a U.S. vulnerability: USGS has noted the U.S. does not produce ferroboron and relies on imports.

• Positions 5E to support domestic NdFeB magnet supply chains amid high global concentration in rare-earth magnets.

This initiative reflects 5E's strategy to expand beyond commodity borates into higher-value derivative materials, potentially enhancing long-term revenue mix, strategic relevance, and customer integration.

"5E's vision has always been to derivatize its upstream feedstock and transition down the value chain. Today the U.S. is import-reliant for ferroboron, a critical component in permanent magnet manufacturing," said Paul Weibel, Chief Executive Officer. "While there has been an obvious need to reinforce the supply chains for rare earths and permanent magnets, the U.S. has a ferroboron deficiency and following engagement with U.S. magnet manufacturers, there is a clear demand and need for a reliable and vertical supply chain in the U.S. 5E has the capability and reliable upstream feedstock to serve that need."

The Company has initiated structured evaluations of engineering pathways, capital requirements, and partnership frameworks. Any production timeline is subject to technical validation, commercial alignment, and financing.
