Key Takeaways
- Shares of Mobix Labs (MOBX) skyrocketed by as much as 81% Thursday following the announcement of a non-binding Letter of Intent to purchase Special Project Delivery LLC (SPD).
- SPD focuses on developing domestic U.S. supply chains for critical minerals and rare earth elements extracted from indigenous sources like coal ash.
- This acquisition would enable Mobix — currently a defense and aerospace technology provider — to enter the strategic minerals industry.
- SPD participates in key federal initiatives, including the $12 billion Project Vault program backed by the U.S. Export-Import Bank.
- Since the LOI is non-binding, completion of a final transaction is not guaranteed.
Shares of Mobix Labs (MOBX) experienced a dramatic surge of up to 81% during Thursday’s trading session after the defense technology firm revealed its intention to purchase Special Project Delivery LLC, an enterprise dedicated to establishing U.S.-based supply networks for critical minerals and rare earth elements.
The equity had already climbed 58% during premarket hours before amplifying those gains once regular trading commenced.
SPD specializes in extracting rare earth elements from American feedstock materials — notably legacy coal ash deposits — through extraction methodologies validated by U.S. defense research institutions. The enterprise was established in 2019.
This prospective transaction would expand Mobix Labs‘ operational footprint beyond its existing position as a manufacturer of sophisticated components and wireless technology solutions for defense and aerospace applications.
James Peterson, Mobix’s Chairman and former Microsemi CEO, characterized critical minerals and rare earths as “one of the defining competitive battlegrounds of the next decade.”
Paul Singarella, SPD’s CEO and a former partner at Latham & Watkins with educational credentials from MIT, described the prospective merger as a natural alignment of SPD’s capabilities with “a publicly traded defense and dual-use technology company already operating inside the defense and aerospace ecosystems.”
The Defense Industry’s Critical Minerals Dependency
The volume of rare earth materials required for modern defense platforms is substantial. Each F-35 Lightning II fighter jet incorporates approximately 418 kilograms of rare earth materials. Virginia-class nuclear submarines demand roughly 4,500 kilograms apiece.
These requirements explain why allied governments have prioritized supply chain sovereignty. International defense alliances including NATO, AUKUS, and Five Eyes have formally designated rare earth independence as a critical geopolitical objective.
Beginning in 2027, the U.S. Department of Defense plans to impose restrictions on specific rare earth magnet materials originating from China, a move anticipated to significantly increase demand for allied-nation supply sources.
SPD’s Government Program Integration
SPD maintains relationships with multiple significant federal initiatives, including Project Vault — the recently unveiled $12 billion U.S. Export-Import Bank public-private collaboration focused on critical-resource security — alongside the Defense Production Act and the Department of Energy’s Loan Programs Office.
The organization also coordinates with the U.S. Departments of Energy and Defense, Lawrence Berkeley National Laboratory, two major American utility companies, and three institutional financial backers.
John Dewey, SPD’s co-founder and CFO, contributes experience overseeing more than $2 billion in combined infrastructure development initiatives.
Mobix Labs operates from its headquarters in Irvine, California, with shares trading on the Nasdaq exchange under the symbol MOBX.
The Letter of Intent remains non-binding and creates a structure for due diligence proceedings and negotiation. No guarantee exists that a definitive agreement will be finalized or that the proposed transaction will reach completion.
