A highly reputable national and multinational customer base across eight market segments reinforces the quality of 5E's boric acid and reflects changing global supply-demand dynamics

HESPERIA, CA / ACCESS Newswire / June 30, 2025 / 5E Advanced Materials, Inc. (Nasdaq:FEAM)(ASX:5EA), a boron and lithium company with U.S. government Critical Infrastructure designation for its 5E Boron Americas (Fort Cady) Complex, announced today that 14 customers have successfully qualified 5E's boric-acid product. Additional customers have requested product or are in advanced phases of the testing process.

Customers that have qualified our product represent a diverse group of industries and market segments such as specialty glass, textile fiberglass, ceramics, insulation, agriculture, defense and chemicals. Testing programs to date have included laboratory evaluation, field trials, and truckload-scale shipments. This progress supports the Company's strategy to build a multi-market customer base across multiple high value sectors.

"We view 2025 as a pivotal year of inflection whereby the boron market will begin to see a deficit in supply, and reliable product in the boron market is expected to become scarce and in short supply. This has been reinforced by the number of customers that have successfully qualified our product. We continue to see strong interest from customers seeking high-purity, U.S. based boron supply and are encouraged by our qualification progress to date," said Paul Weibel, Chief Executive Officer of 5E Advanced Materials. "These customer qualifications underscore our commitment to delivering a secure, U.S.-based source of high-purity boron supply for industries that are central to U.S. priorities and bolster the U.S. industrial base. Of significant importance, I am incredibly proud of 5E's team for successfully passing three LCD glass manufacturers initial product testing protocol as this market segment has some of the most difficult quality requirements across the globe."

The Company believes this progress highlights its continued momentum toward building commercial relationships and advancing its operational and strategic objectives.
