425: Plum Acquisition Corp. III Unveils Strategic Merger with Tactical Resources to Boost U.S. Rare Earth Supply

Plum Acquisition Corp. III announced a proposed business combination with Tactical Resources Corp., a U.S.-focused Rare Earth Elements company, aiming to capitalize on critical mineral demand and enhance domestic supply chains.

Summary

• Plum Acquisition Corp. III (Plum) and Tactical Resources Corp. (Tactical) are pursuing a business combination, involving Plum's domestication to British Columbia, followed by a SPAC Amalgamation and a Tactical Amalgamation, with Pubco and Tactical surviving.
• Tactical Resources is focused on Rare Earth Elements (REEs) mining in the U.S., specifically at the Peak Project in Sierra Blanca, Texas, which utilizes existing tailings from the operational Sierra Blanca Quarry (SBQ).
• Initial testing results from the Peak Project demonstrate high Total Rare Earth Element (TREE) plus Yttrium (Y) extraction levels, ranging from 88% to 93% via direct leach processing.
• The transaction implies a pro-forma fully-diluted enterprise value of $594 million for the combined entity, with Tactical Resources having an implied pre-money equity value of $500 million.
• Tactical Resources shareholders are expected to hold an 81.7% pro-forma equity ownership in the combined company.
• The SPAC Sponsor plans to raise up to $30 million through available financing sources to support the transaction.
• The U.S. has a significant reliance on China for REEs imports (80% in 2021), underscoring the geopolitical importance of domestic supply.
• The U.S. government has shown substantial support for critical minerals through executive orders (e.g., EO 14241, 14156, 14154), the Inflation Reduction Act, and grants from the Department of Defense (~$1 billion since 2020) and Department of Energy (~$150 million since 2021).
• Global demand for NdFeB Magnets is projected to grow dramatically from 119 kilotons in 2020A to 750 kilotons by 2050E, with over 40 kilotons of unmet REEs demand forecasted by 2035.
• The Peak Project is highlighted as a rare 'hard rock direct-to-leach' project, which simplifies the overall processing of REEs.
• The initial property work plan and integrated technical studies for the Peak Project are targeted for completion in Q4 2025.

The future outlook includes completing the business combination, advancing the Peak Project through technical studies, and ultimately achieving commercial production of REEs. Initial property work plan and integrated technical studies are targeted for completion in Q4 2025, paving the way for further development and commercialization.

Management Comments

• Secretary Of Defense Pete Hegseth stated in April 2025: "We're investing in expanding critical mineral production, including rare earth elements, heavy rare earth elements, light rare earth elements, all the things we need that need to be made at home or by our allies and partners."
• Representative Guy Reschenthaler (PA-14) commented: "The production of Rare Earth Elements will spur new economic opportunities for American workers while enhancing national security."
• The U.S. Department of Energy Office of FECM noted: "Rebuilding a domestic supply chain for critical minerals and materials here at home will both safeguard our national security and support the continued development of a clean energy and industrial economy."

Industry Context

This announcement is highly relevant to the broader industry trend of securing critical mineral supply chains, particularly Rare Earth Elements (REEs), which are vital for modern technologies like electric vehicles, semiconductors, and national defense. The U.S. has a stated goal of reducing its significant reliance on China for REEs, making domestic projects like Tactical Resources' Peak Project strategically important. The document highlights substantial government support and legislative actions aimed at fostering a robust U.S. REE industry, aligning with global efforts to diversify supply and enhance national security. The projected dramatic growth in demand for REEs and related products, such as NdFeB magnets, further underscores the industry's expansion and the strategic positioning of companies capable of domestic production.

Comparison to Industry Standards

• Tactical Resources, with an implied pro-forma market capitalization of $612 million, is positioned among U.S.-based REE pure plays, notably smaller than MP Materials Corp. ($7,931 million) but comparable to or larger than some foreign-based REE companies like Brazilian Rare Earths Ltd ($445 million) and Arafura Rare Earths Ltd ($316 million).
• The company is also compared to U.S.-based legacy mining or magnet producers with REE projects such as Energy Fuels Inc. ($1,588 million), USA Rare Earth ($1,142 million), and Ramaco Resources, Inc. ($991 million).
• The REE sector has shown strong performance year-to-date 2025, with comparable companies (MP Materials, Lynas Rare Earths, Energy Fuels, WA1 Resources, USA Rare Earth, Brazilian Rare Earths, Ramaco Resources, Arafura Rare Earths) averaging a 63.6% stock performance increase, significantly outperforming the S&P 500's 6.5% gain, indicating strong industry tailwinds.
• Tactical's Peak Project is distinguished as one of 'only a few extremely rare hard rock direct-to-leach projects in the world,' which simplifies the overall processing compared to more complex traditional methods, potentially offering a competitive advantage in cost and efficiency.
• The Peak Project's location, two miles southeast of the Round Top Rare Earth Elements project operated by USA Rare Earth, suggests it is situated within a geologically prospective and recognized REE-rich area.

Legal Proceedings

• The document mentions a risk related to 'the outcome of any legal proceedings that may be instituted against the Parties, or any of their respective directors or executive officers, following the announcement of the Business Combination,' but does not detail any specific ongoing or past legal proceedings.
