THINGS TO KNOW 14.11.2025

HESPERIA, CA / ACCESS Newswire / November 14, 2025 / 5E Advanced Materials, Inc. ("5E" or the "Company") (Nasdaq:FEAM)(ASX:5EA), a development stage company focused on becoming a vertically integrated global leader and supplier of refined borates and advanced boron derivative materials, today announced key takeaways from its fiscal first-quarter conference call.

Text size:

Chief Executive Officer Paul Weibel outlined momentum across policy, customers, engineering, and financing that supports 5E's path to a Final Investment Decision (FID) in 2026.

Highlights from the call included:

Boron designated a U.S. Critical Mineral (Nov 7, 2025) - The U.S. Geological Survey and Department of the Interior formally added boron to the Final 2025 Critical Minerals List, validating boron's role in U.S. energy, defense, and advanced manufacturing supply chains strengthening Fort Cady's strategic position.
Expanded access to U.S. federal programs - With the critical-mineral designation, 5E believes Fort Cady is eligible for multiple federal funding and financing channels, including EXIM Bank (building on a previously received US$285M Letter of Interest under "Make More in America") and an EXIM Engineering Multiplier application for US$10M to support FEED; additional pools of capital discussed include DOE's LPO, the Office of Strategic Capital, and the U.S. International Development Finance Corporation.
Customer validation advancing - Full-scale product testing is underway with Tier-1 specialty glass manufacturers. A 20-ton shipment of high-purity boric acid arrived in Taiwan for furnace trials; additional LCD-glass producers are queued for shipments. 5E also supplied 1,000 lbs. of boric acid to a U.S. boron-carbide manufacturer supporting domestic re-shoring.
Resource Statement Upgrade - The Company has secured and recorded the remaining federal lode claims for the colemanite deposit. A workstream has commenced to upgrade its mineral resource statement.

Intellectual Property Portfolio - The Company expects to file a portfolio of preliminary patents to secure intellectual property for its proprietary mining techniques and processing solutions.

Engineering and economics - The Company is nearing completion of FEED-ready deliverables. Previously disclosed economics for Phase 1 of Fort Cady continue to anchor planning (approximately 39.5-year mine life, ~16% after-tax IRR, and ~US$469M after-tax NPV), supporting a disciplined, de-risked approach toward construction readiness.
Track to 2026 FID - Priorities include (1) securing non-dilutive U.S. capital support, (2) converting customer progress into commercial offtake agreements, and (3) executing FEED and pre-FID workstreams to ensure construction readiness.

"This quarter represents an inflection point with federal recognition, growing customer traction, and steady execution, placing 5E on a clear path to become America's trusted domestic supplier of advanced boron materials," said Paul Weibel, Chief Executive Officer. "We are progressing methodically, de-risking each stage, and aligning our capital structure to support long-term value creation."
