5E Advanced Materials Provides Additional Details on Integration and Expected Financial Impact of Searles Valley Asset Acquisition

HESPERIA, CA / ACCESS Newswire / October 7, 2026 / 5E Advanced Materials, Inc. ("5E" or the "Company") (NASDAQ:FEAM) today provided additional details regarding its previously announced acquisition of the Searles Valley Minerals assets, including the transaction structure, current operating profile, integration priorities and expected financial contribution. With the acquisition, 5E has transitioned from a development stage company to an operator of an established industrial and critical mineral platform with near term revenue, an experienced workforce and a defined operating plan targeting approximately $40 million of steady-state annual Adjusted EBITDA under its base plan.

Key Highlights of the Transaction * Transforms 5E into a revenue-generating American producer of boron and other critical minerals, adding an established operating platform, infrastructure and workforce to the Company's portfolio. * Acquired the Searles Valley operating platform through a court-supervised Section 363 sale, free and clear of specified legacy liabilities, including the predecessor's debt capital structure and specified historical claims. * Reset the commercial foundation of the business, including new take-or-pay and fixed-price V-BOR® offtake agreements, increasing netbacks by more than 65%, compared with the approximately $424 per short ton realized under predecessor contracts. * Targets approximately $40 million of consolidated steady-state annual Adjusted EBITDA under its base plan, driven by three principal operating levers: contract repricing, cost reduction, and volume recovery with byproduct contribution. * Maintains significant critical-minerals optionality outside the base plan, including opportunities in borates, sulfate of potash, lithium and tungsten. Paul Weibel, Chief Executive Officer of 5E, stated, "This transaction is the single largest step this Company has taken toward its mission. We have gone from a developer with a great deposit and a commercial plan, to a producer with immediate revenue, an experienced workforce, multiple operating plants and products, and a credible, identified path to approximately $40 million of steady-state annual Adjusted EBITDA under our base plan. We bought the operating platform, not the old balance sheet, and we did not pay for the tungsten, lithium or boron-expansion optionality. Our immediate focus is on operating the assets, delivering against the commercial reset and executing the identified path to profitability. At the same time, we believe we have significant opportunities to expand the value of the platform beyond our base plan."
