5E Advanced Materials CEO Paul Weibel Discusses Searles Valley Acquisition Agreement and Path to Revenue Generation at Water Tower Research Insights Conference

HESPERIA, CA / ACCESS Newswire / September 23, 2026 / 5E Advanced Materials, Inc. ("5E" or the "Company") (NASDAQ:FEAM) today announced that Chief Executive Officer Paul Weibel participated in the Water Tower Research Insights Conference held on September 22, 2026.

The discussion followed 5E's recently announced agreement to acquire certain assets of Searles Valley Minerals, Inc., a transaction that, upon closing, is expected to accelerate 5E's transition from a pre-revenue developer to a revenue-generating U.S. critical minerals producer. The press release announcing the agreement is available Here.

During the session, Paul discussed what the proposed acquisition could mean for 5E's growth strategy and investment proposition, including the opportunity to combine Searles Valley's existing production capabilities, established customer base and infrastructure with Fort Cady's large-scale boron resource and long-term growth potential.

Key topics included:

• The 5E enhanced value: How the proposed Searles Valley acquisition is expected to add existing production and revenue to 5E's long-term development platform upon closing.
• Two complementary California assets: The opportunity to combine Searles Valley's operating capabilities and infrastructure with Fort Cady's significant boron resource.
• A growing critical minerals market: The supply-and-demand dynamics supporting boron and its importance across permanent magnets, defense, semiconductors, energy, agriculture and advanced manufacturing.
• A stronger pathway for Fort Cady: How adding an operating asset could support 5E's strategy for advancing Fort Cady while potentially reducing the financing burden associated with developing the project on a standalone basis.
• Building a scaled U.S. platform: The longer-term opportunity for 5E to expand its position across boron, advanced boron materials and other critical mineral products.
