5E Advanced Materials to buy Searles Valley assets, targeting first revenue
What's the deal? 5E Advanced MaterialsDealroom has a profile for this one. Try Dealroom → (NASDAQ:FEAM) has agreed to acquire certain assets of Searles Valley MineralsDealroom has a profile for this one. Try Dealroom →, chief executive officer Paul Weibel confirmed at the Water Tower Research Insights Conference on September 22, 2026. The deal value was not disclosed. Upon closing, it is expected to turn 5E from a pre-revenue developer into a revenue-generating US critical minerals producer.
What's the endgame? 5E is building a vertically integrated supplier of refined borates and advanced boron materials. The plan combines Searles Valley's existing production, customer base, and infrastructure with 5E's large-scale Fort Cady boron resource in Southern California.
Why now? Boron was added to the US Department of the Interior's 2025 Critical Minerals List, and the Fort Cady resource is designated as Critical Infrastructure by the Department of Homeland Security. Weibel framed the two California assets as complementary steps toward a scaled US platform.
Why it matters: Adding an operating asset could support Fort Cady's development while reducing the financing burden of building the project on a standalone basis. 5E cited demand across permanent magnets, defense, semiconductors, energy, agriculture, and advanced manufacturing.
What could go wrong? The transaction requires approval from the Bankruptcy Court and remains subject to closing conditions. Neither the timing nor the financial impact is guaranteed.
The signal: Governments are pushing to secure domestic supply chains for critical minerals, and 5E's move reflects developers pairing early-stage resources with operating assets to speed the path to revenue.
