Shares of Mobix Labs (MOBX) surged by as much as 81% during Thursday’s trading session after the defense technology firm unveiled its intention to purchase Special Project Delivery LLC, a company dedicated to establishing U.S.-based supply chains for rare earth elements and essential minerals.
The equity had already climbed 58% during premarket hours before continuing its upward trajectory once regular trading commenced.
SPD specializes in extracting rare earth elements from domestic sources — particularly legacy coal ash deposits found throughout the United States — utilizing extraction methods that have received validation from U.S. defense research organizations. The enterprise was established in 2019.
This proposed transaction would represent a significant strategic pivot for Mobix Labs, expanding the company’s operations beyond its existing position as a provider of sophisticated components and wireless solutions for defense and aerospace applications.
James Peterson, Chairman of Mobix and former Microsemi CEO, characterized rare earths and critical minerals as “one of the defining competitive battlegrounds of the next decade.”
Paul Singarella, SPD’s Chief Executive Officer and former Latham & Watkins partner with Massachusetts Institute of Technology credentials, described the prospective merger as a natural alignment between SPD’s operational platform and “a publicly traded defense and dual-use technology company already operating inside the defense and aerospace ecosystems.”
The Strategic Importance of Rare Earths in National Defense
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 per vessel.
These substantial requirements explain why allied governments have prioritized supply chain autonomy. International alliances including NATO, AUKUS, and Five Eyes nations have all publicly designated rare earth supply independence as a critical geopolitical objective.
Beginning in 2027, the U.S. Department of Defense plans to implement restrictions on specific Chinese-origin rare earth magnet materials, a policy shift anticipated to drive increased demand for allied supply sources.
Federal Program Alignment and Strategic Partnerships
SPD maintains strategic alignment 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 Loan Programs Office.
The organization has also established public partnerships with the U.S. Departments of Energy and Defense, Lawrence Berkeley National Laboratory, two major American utility companies, and three institutional financial entities.
John Dewey, SPD’s co-founder and Chief Financial Officer, contributes experience overseeing more than $2 billion in cumulative infrastructure development projects.
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 conducting due diligence and negotiating terms. No guarantee exists that the parties will execute a definitive agreement or successfully complete the proposed transaction.
