5E ADVANCED MATERIALS PROVIDES SHAREHOLDER UPDATE CALL HIGHLIGHTING BY-PRODUCT DECISION AND FIRST COMMERCIAL DELIVERY OF BORIC ACID

Company unveils strategic decision to progress forward with calcium chloride as optimal by-product to reduce CAPEX, reports positive operational progress on its small-scale facility production and plant operations, commercial developments, and capital funding

HESPERIA, CA., November 21, 2024 (GLOBE NEWSWIRE) - 5E Advanced Materials, Inc. (Nasdaq: FEAM) (ASX: 5EA) (“5E” or the “Company”), a boron and lithium company with U.S. government Critical Infrastructure designation for its 5E Boron Americas (Fort Cady) Complex, today provides a shareholder update and review of the first quarter ended September 30, 2024.

HIGHLIGHTS

•5E has assessed and scoped its commercial phase design package to include calcium chloride production, which we anticipate will reduce Phase 1 commercial CAPEX by approximately 15% and improve project rates of return;

•5E’s commercial progress is advancing with momentum as the Company has delivered its first full truckload shipment of boric acid super sacks to a U.S. customer;

•The Company’s expanded cost optimization initiative has further streamlined operations, and is estimated to yield approximately $2.2 million in operating expense improvement for calendar year 2025;

•The Company’s small-scale boron facility has achieved its optimized steady-state production rate of 1 short ton per day of boric acid, a level which is designed to meet volumetric needs for expanded customer qualification, testing needs for our commercial strategy, and minimize liquidity impact;

•Operational process improvements have yielded improved product quality and consistency, with production now consistently exceeding desired customer specifications; and

•The Company’s capital funding strategy has been advanced with the receipt of a letter-of-intent from the Export-Import Bank of the United States (“EXIM”) for the potential creation of a facility to backstop up to $285 million in project debt financing, subject to EXIM’s final approval.

“Over the last three months, 5E has made significant progress across the most critical elements of our strategy and go-forward plan as we advance our 5E Boron Americas project (the “Project”) towards commercial scale production,” said Paul Weibel, Chief Executive Officer of 5E Advanced Materials. “We’ve made the critical strategic decision to pursue calcium chloride as our byproduct and have now begun incorporating this decision into our commercial basis of design. We believe that the pursuit of calcium chloride for our by-production alongside boric acid has the potential to ultimately yield a significant decrease in our CAPEX needed for our commercial scale development, to meaningfully improve the Project’s rate of return, and to further embed long-term shareholder value creation to the Project.”

Weibel continued “Our commercial strategy is advancing with momentum, and we recently met a key milestone in our timeline through the delivery of our first truckload of boric acid super sacks to a U.S. customer. We recently added two seasoned borates sales and marketing professionals which have already helped 5E make important advancements in translating customer engagement to initial off-take discussions, and we’re currently in process of negotiating contracts for 25-to-50% of our initial boric acid production in commercial Phase 1, with a line of sight towards securing tonnage of boric acid in the coming months that will go towards Phase 2. Additionally, we’ve expanded the geographic reach of commercial program to the APAC region, with coverage over more than 80% of the global borates demand as we look to high-grade the margin profile of our commercial scale production through targeted industry segmentation.”

Weibel concluded, “We’ve aligned and optimized our plant-level production rates and overall operations and production processes, which has resulted in operating cost reductions and an improvement in the quality and consistency of our boric acid production. 5E is working to accelerate across its operational and commercial strategy playbook, and we remain on path to complete an optimal design with pre-feed engineering work and progress our Project and development towards production of boric acid at commercial scale. Our commercial strategy execution has gained encouraging momentum as we’ve advanced customer offtake discussions and recently delivered our first shipment of boric acid to a customer. We will remain diligent with a keen focus on operational and commercial execution to help support our long-term funding strategy. We have a clear roadmap ahead of us in the next twelve months, and we look forward to delivering on our Project’s value enhancing catalysts as we complete pre-feed engineering and prepare the Project for commercial scale development and production in the coming year.”
