Key Takeaways
- Shares of Mobix Labs (MOBX) soared up to 81% Thursday following the announcement of a non-binding Letter of Intent to purchase Special Project Delivery LLC (SPD).
- Special Project Delivery specializes in developing domestic supply chains for rare earth elements and critical minerals extracted from U.S. sources, including coal ash waste.
- This acquisition would position Mobix — currently a defense and aerospace technology provider — to enter the critical minerals industry.
- SPD participates in federal initiatives such as Project Vault, a $12 billion public-private partnership backed by the U.S. Export-Import Bank.
- The Letter of Intent is preliminary and non-binding, meaning final transaction completion remains uncertain.
Shares of Mobix Labs (MOBX) climbed as much as 81% during Thursday’s trading session following the company’s revelation that it intends to acquire Special Project Delivery LLC, a specialized platform dedicated to establishing domestic supply chains for rare earth elements and critical minerals.
The stock initially surged 58% during premarket hours before momentum accelerated further after the opening bell.
Special Project Delivery extracts rare earth elements from domestic materials — particularly legacy coal ash deposits from U.S. power plants — utilizing extraction methodologies that have been validated by U.S. defense research organizations. The company was established in 2019.
This proposed transaction would allow Mobix Labs to expand beyond its existing operations as a developer of sophisticated components and wireless technologies serving defense and aerospace applications.
James Peterson, Chairman of Mobix and former Microsemi CEO, stated that rare earths and critical minerals have emerged as “one of the defining competitive battlegrounds of the next decade.”
Paul Singarella, SPD’s CEO and former Latham & Watkins partner with educational credentials from MIT, characterized 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 Strategic Importance of Rare Earths in Defense Applications
The quantities of rare earth materials required for modern defense systems are substantial. Each F-35 Lightning II fighter jet contains approximately 418 kilograms of rare earth materials. A single Virginia-class nuclear submarine requires roughly 4,500 kilograms.
These substantial requirements explain why allied nations have prioritized supply chain sovereignty. Strategic alliances including NATO, AUKUS, and Five Eyes countries have all designated rare earth independence as a critical geopolitical objective.
Beginning in 2027, the U.S. Department of Defense plans to implement restrictions on certain rare earth magnet materials sourced from China, a policy change anticipated to significantly increase demand for allied supply chains.
Federal Program Alignment and Strategic Partnerships
Special Project Delivery maintains alignment with numerous significant federal initiatives, including Project Vault — the recently unveiled $12 billion U.S. Export-Import Bank public-private collaboration focused on critical-resource security — along with Defense Production Act programs and the Department of Energy Loan Programs Office.
The organization also maintains public partnerships with the U.S. Departments of Energy and Defense, Lawrence Berkeley National Laboratory, two major U.S. utility companies, and three institutional financial backers.
John Dewey, SPD’s co-founder and Chief Financial Officer, contributes experience spanning over $2 billion in cumulative infrastructure development projects.
Mobix Labs operates from its headquarters in Irvine, California, and maintains a Nasdaq listing under the ticker symbol MOBX.
The Letter of Intent remains non-binding and creates a framework for conducting due diligence and continuing negotiations. No guarantees exist that a definitive agreement will be finalized or that the proposed transaction will ultimately close.
