HESPERIA, CA / ACCESS Newswire / July 23, 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, highlighted commercial progress, strengthening global boron market fundamentals and continued advancement of its Fort Cady Boron Project during a Water Tower Research Fireside Chat.

5E's CEO, Paul Weibel, discussed accelerating commercial execution, including five customer Heads of Agreement (HOAs), one Letter of Intent (LOI), and ongoing discussions with additional domestic and international customers. These commercial milestones demonstrate increasing customer demand for a reliable U.S. source of boric acid while supporting the Fort Cady Project's path toward commercial production and bankability.

The Company also discussed strengthening fundamentals across the global boron market, noting that demand continues to outpace supply as governments and manufacturers prioritize secure domestic critical mineral supply chains. With boron designated as a U.S. Critical Mineral, limited new boron projects advancing globally and increasing demand across advanced manufacturing, defense, energy, agriculture and industrial applications, management believes the Fort Cady Boron Project is well positioned to become one of North America's most significant future sources of boric acid and advanced boron materials.

In addition to boric acid production, management highlighted opportunities to create additional long-term value through higher-value boron derivative products, including metaboric acid and ferroboron materials, as well as potential by-products such as lithium carbonate and calcium-based products, expanding Fort Cady's future commercial opportunities and strengthening the Company's vertically integrated growth strategy.

"Over the past several months, we have made meaningful progress executing our commercial strategy, demonstrating growing customer interest in establishing a reliable domestic source of boric acid," said Paul Weibel, Chief Executive Officer. "As global boron market fundamentals continue to strengthen, we believe Fort Cady is uniquely positioned to supply critical boron materials needed across advanced manufacturing, energy, defense and other strategic industries while creating long-term value through product diversification."

Key topics discussed included:

• Commercial progress, including five customer agreements and continued expansion of the customer pipeline

• Strengthening global boron supply and demand fundamentals

• Growing demand for reliable U.S.-based boric acid supply

• Development of higher-value products, including metaboric acid, ferroboron and lithium carbonate

• Advancement toward FEED engineering and project bankability

• The strategic importance of the Fort Cady Boron Project in supporting U.S. critical mineral supply chains
