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 quarter ended December 31, 2022.

During the quarter ended December 31, 2022, the Company substantially advanced construction of the Small-Scale Facility and commenced pre-commissioning activities prior to quarter end. The Company continues to focus on and targets commencing operations for initial production of boric acid in late first quarter or early second quarter of calendar year 2023. The timing of initial production of boric acid is contingent upon the successful completion of commissioning activities and the final clearance to commence mining from the Environmental Protection Agency under the Company’s Underground Injection Control permit, which is expected to be issued in the ordinary course of business. The production of boric acid will make 5E the third producer of boron in the United States. The Company continues to target initial production of lithium carbonate in the second quarter of 2023.

As announced on December 20, 2022, the Company is considering opportunities to accelerate the timeline for initial commercial production based on the learnings from the Small-Scale Facility. The opportunities to accelerate the timeline for initial commercial production are underpinned on the belief that the sooner the Company can enter commercial production, the sooner the Company can achieve positive earnings and cash flow. There have been significant increases in prices for boron and lithium over recent quarters, largely driven by supply constraints which appear unlikely to dissipate in the near term. The Company’s independent market research indicates medium-to-long term strength in boric acid demand and pricing, which further reinforces the need to explore all options to accelerate commercial production. The initial focus to accelerate includes developing model estimates for capital cost, operating expenses and revenue based on modular design options. The Company anticipates using the data and flow sheet optimization derived from the initial production from the Small-Scale Facility to optimize the larger scale production strategy. 5E aims to quickly transition into engineering and long lead time item acquisitions required to support the plans to achieve commercial production as soon as possible.

The Company is assessing partner-led initiatives to produce downstream derivatives (including, but not limited to, boron specialties and advanced materials) from the Small-Scale Facility. While this is a secondary focus, the Company has made progress with respect to certain initiatives with the opportunity to deliver revenue prior to the planned larger scale facility becoming operational.

During the quarter, the Company entered into a non-binding letter-of-intent with Estes Energetics, a current supplier to the U.S. Department of Defense, to collaborate on producing boron advanced materials for solid rocket motors to support U.S. space and military industries. The letter-of-intent aligns with on-going U.S. government initiatives and programs to on-shore production of critical materials. In addition to the above, the Company continues to have discussions with prospective and already engaged customers with respect to broader collaboration on boric acid and lithium carbonate sales including customer funded development options.

The Company continues to pursue various government funding opportunities and incentives and is targeting funding opportunities in areas of interest for the U.S. government, including defense, clean energy, agriculture, and food security. The focus to date has been the Department of Defense, via the Defense Production Act Title III and the Defense Logistics Agency, as well as the Department of Energy through the Office of Fossil Energy and Carbon Management and the Loans Program Office. While discussions are ongoing with multiple governmental entities, the Company expects to be able to have more meaningful discussions with the Loans Program Office upon the completion of an updated technical report. In October 2022, the Company received a partial exemption for use tax within the State of California for plant and equipment procured to process boric acid and lithium carbonate. The partial exemption is being retroactively applied to the Small-Scale Facility and we expect to also apply the exemption to the larger facility.

During the quarter, capital market activities were primarily focused on the United States but included a two-week Australia non-deal roadshow where senior management presented extensively in four Australian states and territories. Multiple non-deal roadshows are scheduled for the upcoming quarter and the Company continues to work with investment banks to increase awareness to investors in the United States. The Company commenced a process to consider non-dilutive debt financing options for our larger scale facility.

The process to recruit a new CEO for the organization is well underway. More broadly, the Company continues to execute on its aspiration of becoming a meaningful producer of boric acid, lithium carbonate, and boron advanced materials. Operationally there is a clear strategy to deliver real shareholder value with a focus on four workstreams that are each being driven by experienced executives:

Boron and Lithium Complex: focused on initial production from the Small-Scale Facility, transitioning the Small-Scale Facility to produce advanced materials, and developing options to accelerate larger commercial production – Chris Knight

Commercial Products and Partners: focused on customer-led initiatives for advanced materials production and customer partnerships to advance the construction and operations for larger-scale commercialization – Dr. Dino Gnanamgari

Debt Capital Markets, Project Finance, and Government Affairs: focused on non-dilutive capital to finance construction and operations for larger-scale commercialization – Paul Weibel

Equity Capital Markets and Investor Outreach: focused on continuing to educate institutional and retail investors, in association with investment banks, of 5E’s story and potential value – J.T. Starzecki

As of quarter-end, the Company maintained a cash balance of $56.8 million and an available cash balance of $46.8 million. Construction in progress was $46.9 million, compared to $33.3 million in the prior fiscal quarter ended September 30, 2022 as the Company advanced construction and pre-commissioning activities for the Small-Scale Facility.

For the three months ended December 31, 2022, project expenses increased 14% as plugging and abandonment costs during the current quarter exceeded the reduction in costs related to the prior year’s quarter water monitoring well activity. General and administrative costs were essentially flat compared to the prior year's quarter.

During the quarter, the Company recognized an unrealized loss resulting from the change in fair value of the convertible note derivative liability. Interest expense increased due to the issuance of the convertible note and inclusion of debt issuance cost and discount amortization, while interest income increased as we are investing excess cash in U.S. Treasury Bills.

5E Advanced Materials, Inc. (Nasdaq: FEAM) (ASX: 5EA) is focused on becoming a vertically integrated global leader and supplier of boron specialty and advanced materials, complemented by lithium co-product production.
