Fort Cady named among projects highlighted in President Trump's $2 billion critical minerals initiative at the American Mining Roundtable; project advances toward Final Investment Decision

Initial $8 Million Investment has the potential to unlock $285 million in project-level debt

HESPERIA, CA / ACCESS Newswire / August 10, 2026 / 5E Advanced Materials, Inc. ("5E" or the "Company") (NASDAQ:FEAM), a company focused on becoming a vertically integrated global leader and supplier of refined borates and advanced boron derivative materials, today welcomed the White House's recognition of the Company's Fort Cady Integrated Boron Facility and the Export-Import Bank of the United States' $8 million investment supporting the project. Together, these announcements underscore the federal government's growing commitment to strengthening America's domestic critical mineral supply chain.

The Export-Import Bank of the United States announced an $8 million investment to support development of the Fort Cady Project, further advancing one of the nation's most significant domestic boron resources. This initial investment is a precursor to 5E's application for a $285 million project debt facility, for which the Company has already received a letter of intent. Boron is a critical mineral that supports defense applications, semiconductor manufacturing, advanced materials and other technologies essential to America's industrial and national security. Fort Cady is fully permitted, designated Critical Infrastructure by the U.S. Department of Homeland Security, and is advancing through engineering, financing and customer development toward a Final Investment Decision. In recent weeks, the Company has also announced four commercial agreements, demonstrating growing market demand for a domestic source of boron.

On Friday, August 7, President Donald J. Trump hosted the American Mining Roundtable, where he announced more than $2 billion in investments to accelerate domestic critical mineral production. The accompanying White House Fact Sheet specifically recognized the Fort Cady Integrated Boron Facility among the strategic projects supporting the Administration's efforts to rebuild America's critical mineral supply chain.

"Today's announcements reinforce the importance of developing critical minerals here at home," said Paul Weibel, Chief Executive Officer of 5E Advanced Materials. "We are honored that the White House recognized the Fort Cady Project as part of the Administration's efforts to strengthen domestic supply chains. As the United States works to reclaim leadership in critical minerals, Fort Cady is uniquely positioned to become a reliable domestic source of boron, a critical mineral essential to defense, semiconductors, advanced manufacturing, energy infrastructure, agriculture and other strategic industries. We look forward to advancing Fort Cady as a cornerstone of America's critical mineral future."

As the only advanced-stage boron project under development in the United States, Fort Cady is expected to produce high-value boron specialty materials while also recovering lithium as a co-product. Boron is designated as a U.S. critical mineral and is an essential input across a broad range of high-value industries, including permanent magnets, semiconductors, advanced glass and ceramics, aerospace, defense technologies, fiberglass, insulation, fertilizers, energy infrastructure and advanced manufacturing. These applications underpin long-term global trends, including electrification, artificial intelligence, grid modernization, domestic manufacturing and defense modernization, that are expected to drive sustained demand for boron products. Fort Cady is being developed to establish a secure domestic supply of this strategic material, helping reduce U.S. reliance on foreign sources while supporting resilient domestic supply chains.
