HOUSTON, Nov. 10, 2022 (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 announced its financial results for the quarter ended September 30, 2022. The Company also invites shareholders and interested parties to a pre-recorded Investor briefing to be released on the Company's website on Wednesday, November 16, 2022 at 4:30pm EST.

First Quarter 2023 Financial Highlights:

As of quarter-end, the Company maintained a cash balance of $74.2 million and an available cash balance of $64.2 million. Construction in progress was $33.3 million, compared to $25.6 million in the prior fiscal quarter ended June 30, 2022 as the Company advances construction of the SSBF.

Project expenses decreased 25% year-over-year, primarily due to a $4.2 million reduction in drilling activity for water monitoring wells, partially offset by a $3.0 million increase in plugging, abandonment, and other site expenses. General and administrative expenses decreased by 16% year-over-year, primarily driven by $2.0 million of non-recurring costs incurred during the three months ended September 30, 2021 relating to the Company's Nasdaq listing and reorganization. The absence of these costs during the last reported period were partially offset by a $0.3 million increase in liability insurance and $0.6 million increase in salaries and benefits due to an increase in predominantly operational headcount from 11 at September 30, 2021 to 27 at September 30, 2022. Research and development expenses increased year-over-year as the Company progressed its advanced materials strategy and depreciation and amortization expenses increased as the Company began placing assets into service.

During the quarter, the Company recognized a $13.9 million unrealized gain 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 $0.6 million of debt issuance cost amortization, while interest income increased after purchasing a certificate of deposit in September 2022.
