Borate Product Successfully Passed All Qualification Parameters; Successful Trial Unlocks Path to Offtake Agreement
HESPERIA, CA / ACCESS Newswire / January 8, 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 its boric acid successfully passed all qualification parameters in a 20-ton commercial tank trial. The trial, conducted by a major U.S.-headquartered LCD glass manufacturer, began in December and represents a key step toward a potential initial offtake agreement and an important advancement in the Company’s commercialization strategy. The full qualification program included evaluation of key impurity profiles, moisture content, particle size distribution, flowability, and a logistics and shipping evaluation in a commercial manufacturing environment. 5E’s product met the customer’s specifications across these parameters for LCD glass production.
“Completing this customer qualification trial demonstrates another meaningful milestone on 5E’s path to commercialization and positions 5E with the necessary customer approvals for an offtake agreement,” said Paul Weibel, Chief Executive Officer. “We believe this commercial validation successfully demonstrates 5E’s capabilities to produce on-spec product in commercial quantities for the LCD glass industry and positions the company to secure its first offtake agreement.”
Trial Highlights
-
Completion of 20-ton commercial tank trial with all qualification parameters met
-
Concludes a multi-stage qualification program, including lab analysis, a supply chain trial, and a successful commercial tank trial
-
Demonstrates ability to deliver an on-spec product at commercial quantities, including logistics and handling performance
-
Next step: advance offtake discussions toward commercial terms
The customer qualification process spanned approximately eight months and included lab testing, supply chain validation, and a full commercial tank trial. The LCD glass industry requires some of the highest quality standards in the borate market, and the major customer for whom 5E has successfully qualified its product maintains a multi-stage testing and qualification program. Testing of 5E’s product began in April 2025 when samples passed an initial technical evaluation and lab-based glass melting process. Upon the successful lab trial, 5E’s product was recommended for a supply chain trial which 5E successfully passed in August 2025. The supply chain trial was another critical step to assist in gauging finished product moisture levels and assessing flowability before input into a real-time glass manufacturing environment. In October 2025, 5E shipped 20 tons of boric acid to Southeast Asia for the customer to conduct a tank trial in a commercial manufacturing environment. 5E was notified in early December 2025 that the trial commenced and initial performance indications were positive. With the trial complete, 5E’s product has passed all required testing parameters and confirmed the product produced meets specifications for LCD glass manufacturing.
In addition to LCD glass manufacturing, boron is a critical mineral that enables modern day technological and everyday applications. Boron strengthens solar panel glass, improves battery performance and durability, creates a safer nuclear reactor by absorbing neutrons, and supports the lightweight armor that protects American troops. In aerospace, boron-based composites boost performance by reducing weight, and in agriculture, boron fertilizers enhance crop yields. Boron’s recent inclusion on the United States Department of Interior’s 2025 Critical Minerals List, together with the designation of 5E’s facility as Critical Infrastructure, reinforces the strategic importance of 5E’s potential entry into this concentrated market. These applications underscore the importance of establishing a reliable domestic boron supply chain to support U.S. manufacturing, energy security, and defense readiness.
