5E Advanced Materials has signed an offtake heads of agreement, or HOA, with a domestic cellulose insulation company for the purchase of boric acid and calcium sulphate products from the company's Fort Cady Integrated Boron Facility in Southern California. Boric acid is a required fire-retardant additive in virtually all cellulose insulation, and the agreement signals a domestic manufacturer is moving to lock in a U.S.-based supply source ahead of Fort Cady's full-scale production. This is the third commercial offtake milestone 5E Advanced Materials has announced in approximately 60 days.

5E Advanced Materials announced it has signed an indication of interest with a domestic industrial end-user for the purchase of boric acid and calcium sulphate products from the Company's Fort Cady Integrated Boron Facility. This marks the Company's second commercial milestone in two months, further demonstrating growing customer demand. The IOI outlines the preliminary interest of a U.S.-based industrial customer in purchasing boric acid and calcium sulphate products from 5E, contemplating a 5-year term with an annual minimum offtake volume of approximately 3,750 short tons of boric acid and calcium sulphate and a maximum offtake volume of approximately 4,500 short tons of both products, at a fixed price subject to an annual escalation. The arrangement is subject to satisfactory evaluation of product quality and specifications, evidence of consistent production capability, and the negotiation and execution of a definitive purchase agreement. The IOI follows the first offtake heads of agreement, a 10-year term agreement with a domestic industrial customer, announced in May 2026, and reflects ongoing momentum from 5E's customer engagement efforts across multiple industrial end markets. 5E continues to advance discussions with this and other prospective customers, with the goal of converting non-binding indications of interest and heads of agreement into definitive, binding offtake agreements that support the Fort Cady Project's path toward a Final Investment Decision.

5E Advanced Materials highlighted key takeaways from its live investor webinar, including strengthening boron market fundamentals, commercial progress and emerging growth opportunities. During the webinar, management discussed a global boron market, increasing demand for domestic supply and the Company's ongoing efforts to advance customer discussions and future offtake opportunities. The Company also provided updates on its recently announced Lithium Carbonate Preliminary Economic Assessment, PEA, as well as opportunities to develop higher-value products such as Meta Boric Acid and magnet-grade boron materials.
