The Fort Worth Press - 5E Advanced Materials Ships 20 Tons of Boric Acid from U.S.-Based Fort Cady Operations for Specialty Glass Trial

HESPERIA, CALIFORNIA / ACCESS Newswire / October 14, 2025 / 5E Advanced Materials, Inc. ("5E" or the "Company") (Nasdaq:FEAM)(ASX:5EA), a development stage company focused on becoming a vertically integrated global leader and supplier of refined borates and advanced boron derivative materials, today announced the shipment of 20 tons of boric acid produced from its Fort Cady operations in Southern California. Later this week, the Company plans to ship an additional 1,000 pounds of boric acid for domestic boron carbide (B4C) production.

These shipments mark important milestones as the Company advances toward commercial production. The boric acid will be delivered to potential customers for evaluation and qualification as part of 5E's ongoing engagement with downstream users in the energy, specialty glass, and defense sectors. China currently controls much of the boron carbide supply chain with limited alternative sources to secure the critical material domestically.

"Shipping 20 tons of high-quality boric acid represents an important step in our transition from development to commercial operations," said Paul Weibel, Chief Executive Officer of 5E Advanced Materials. "These shipments confirm the quality of our product and the reliability of our process technology, reinforcing confidence in our near-term production path and our mission to establish a secure, U.S. supply of boron for industries that bolster national security and drive economic export growth."

5E continues to focus on building a secure, U.S.-based supply of boron to support the energy transition, decarbonization and national security applications. The Company's Fort Cady facility remains one of the largest known undeveloped boron deposits in North America and has been designated Critical Infrastructure by the U.S. Department of Homeland Security.
