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 announced its financial results for the fiscal year end 2022.

Corporate Strategy

5E and boron sit at the convergence of three global mega-trends: decarbonization, food security, and domestic supply of critical materials. The Company is positioned strategically to benefit from the expected surge in demand for boron and lithium as a result of high-growth decarbonization technologies which commonly utilize these advanced materials as key inputs, the recognition of boron’s importance to keep the world fed as an essential micronutrient required by crops, and the move to reduce reliance on foreign sourcing and processing in a critical supply chain.

Given existing geological limitations, there are few major known boron projects globally. 5E possesses the largest, and only substantially permitted, of these six projects. The 5E Boron Americas (Fort Cady) Complex in Southern California, which hosts the largest known new conventional source of boron in the world, is designated as Critical Infrastructure by the U.S. government.

With approximately 85% of global supply coming from two commodity miners, 5E is well positioned to execute its corporate strategy of becoming a high-margin, high-value, vertically integrated producer of boron and lithium specialty and advanced materials. With this strategy, the Company will be positioned to take advantage of its boron and lithium supply and potentially favorable cost position, particularly in the highly fragmented downstream boron market with few vertically integrated suppliers.

In May 2022, 5E announced plans to expand the production capacity of its large-scale complex to 500,000 tons per year of boric acid. The Company also announced its goal to sell boron advanced materials to take advantage of higher pricing, operational synergies, and the currently fragmented market. The global advanced materials supply chain is at risk of disruption, with an over-reliance on Turkey and China for sourcing and processing, respectively. The U.S. government, as well as certain of 5E’s customers, has also sought to domesticate the boron supply chain, which aligns with 5E’s strategy to create a vertically integrated U.S. based complex. 5E also announced potential lithium carbonate production of several thousand tons per year upon completion of the large-scale complex, which could make 5E one of the largest producers of lithium in the U.S.

Customer and Strategic Partnerships

As part of the commercialization plans, 5E has dedicated resources to secure strategic collaboration agreements with customers that could include offtake and financing support linked to the supply of boric acid, boron advanced materials, and lithium carbonate. During the fiscal year, the Company signed non-binding letters of intent with Corning Incorporated and Borman Specialty Materials.

Corning Inc. is a Fortune 300 company and one of the largest technical glass manufacturers in the world. Under the letter of intent, 5E would supply boron specialty materials while collaborating with Corning to develop and supply boron advanced materials. Borman is a U.S. producer of boron and other advanced materials that supply future facing global markets within the semiconductor, life sciences, aerospace, military, and automotive industries. Under the letter of intent, 5E would supply Borman with boric acid and boron advanced materials. The Company is also advancing discussions with other customers who are also interested in ensuring domestic supply of boron and lithium.

The Company executed research agreements with leading academic institutions Georgetown University (“Georgetown”) and Boston College. Both research agreements position 5E to potentially develop intellectual property and commercialization pathways within downstream boron-based decarbonization applications. 5E’s research agreement with Georgetown aims to enhance the performance of permanent magnets by increasing the use of boron. The Company’s research agreement with Boston College intends to advance boron-based materials within solar energy systems. Solar energy is expected to play an important role in serving the increased demand for a carbon-neutral global economy and the agreement has the potential to create boron-based materials that serve the accelerating, future-facing solar marketplace.

5E Boron Americas (Fort Cady) Complex

The SSBF is expected to serve as a foundation for the design of the large-scale complex and to support potential cost optimization and value engineering. The SSBF is also an essential step for the Company to deliver product to potential customers and to progress downstream boron advanced materials capabilities. The Company has made substantial progress on the SSBF this year after completing detailed engineering, procuring and receiving long-lead item equipment, increasing staffing, completing four supply wells, assigning the construction contract to Matrix Service, and breaking ground on construction. Importantly, there have been no lost time injuries for any 5E sites during the year, as the Company continues to prioritize the safety and well-being of personnel.

The SSBF is on schedule for mechanical completion in CQ4 2022 and first production in early 2023. With a target production of 2,000 tons per year of boric acid, the SSBF provides considerable optionality for the Company to continue delivering on its corporate strategy.

Engineering, design, and construction for the large-scale complex is targeted to occur after operations of the SSBF with mechanical completion in 2025. Initial production capacity of the large-scale complex is targeted at 250,000 tons per year of boric acid and several thousand tons per year of lithium carbonate. Capacity is later targeted to increase to 500,000 tons per year of boric acid and several thousand tons per year of lithium carbonate with incremental capacity expansions.

Marketing Initiatives

In December 2021, the Company announced the engagement of Bank of America as capital markets advisor and the fiscal year-end culminated with the Company’s inclusion in the Russell 2000^®, 3000^®, and Microcap^® indices, the MSCI Global Small Cap Australia index, and, most recently, the ASX 300 index. Inclusions in these major indices has placed the Company’s securities in the portfolios of some of the world’s largest global asset management firms. The Company continues to pursue further index inclusions to increase investor awareness and demand for 5E securities. The Company has participated in several investor conferences, including the Baird 2022 Vehicle Technology & Mobility Conference, Canaccord Genuity 42nd Annual Growth Conference, and the Credit Suisse 35th Annual Specialties and Basics Conference.

The Company continues to increase its marketing efforts, recently launching a new investor presentation that highlights the significance of boron and lithium in enabling three global mega trends: decarbonization, food security, and onshoring critical materials. The Company also hired a Chief Marketing Officer and a Marketing Manager to further promote 5E and boron to investors and other stakeholders. Over the coming months, 5E plans to launch extensive marketing campaigns that includes in-person and virtual investor presentations, social media outreach, and print and video press. The Company will also participate in several other investor conferences and host site tours of its 5E Boron Americas (Fort Cady) Complex.

Boron remains a relatively unknown material to the investment community despite its use in everyday and future facing applications. As such, adding resources to educate and mainstream boron could unlock value for shareholders as the Company is focused on becoming a global leader in the material.

Corporate Activities

5E’s team in California and Texas continues to grow with several new hires across operations, administration, marketing and finance, including a VP of Operations with more than 19 years of experience at Albemarle Corporation that spans across multiple disciplines including process design, purchasing, M&A, and general management. The Company also hired a Chief Accounting Officer with more than 29 years of accounting experience at PricewaterhouseCoopers and natural resources companies. As of fiscal year-end, the majority of administrative and operational personnel have transitioned to the U.S. after a successful reorganization and U.S. listing on Nasdaq in March 2022. Local hiring in California is expected to increase as the Company works towards completion of the SSBF and scaling of the business.

In light of the recent Presidential Executive Orders and U.S. government initiatives to onshore and secure production of critical materials, the Company has increased its government affairs effort by engaging a specialized management consulting firm in May 2022 to pursue federal, state, and local funding opportunities. In February 2022, the Integrated Boron Facility successfully received Critical Infrastructure designation by the U.S. Department of Homeland Security, validating the domestic security pillar of the three global mega-trends.

5E continues to advance its efforts around environmental, social, and governance (“ESG”), and has been working with a North American sustainability consulting firm to bolster our ESG and sustainability strategy and future reporting framework.
