MP Materials shares surged on Wednesday after the company announced a joint venture with Saudi Arabia’s Ma’aden to build a rare-earths processing and magnet manufacturing hub in the kingdom, a move that positions the U.S. producer inside one of the world’s fastest-growing critical-minerals investment programs. The partnership will give MP a new downstream base in the Gulf as Saudi Arabia accelerates its bid to become a major player in the global rare earth supply chain.
The companies will establish a refinery and separation plant that will take Saudi and allied feedstocks through to finished rare eaarth oxides and magnet materials, according to MP Materials’ confirmed statement in its investor update. The venture is structured to give Ma’aden control of domestic supply development while MP provides the processing technology and downstream magnet expertise, creating what both sides describe as a fully integrated Gulf-based platform for critical minerals.
MP Materials shares traded at $64.04 in early afternoon on Wednesday, up 9.4% on the session and extending a rally that has lifted the stock nearly 290% year-to-date. The Saudi venture immediately drew investor interest given its potential to expand MP’s downstream position beyond Mountain Pass and anchor a non-Chinese refining route at a time when Western supply chains remain tight.
MP’s expansion into Saudi Arabia comes after a series of agreements that have pulled the company deeper into U.S. strategic supply-chain planning, including its earlier deal with the Department of Defense to support domestic rare-earth processing and magnet production. The company’s investor disclosure confirms that Washington backed MP’s U.S. facilities as part of a broader effort to rebuild non-Chinese refining capacity, a role that has made MP one of the few upstream-to-downstream players positioned to supply both commercial and defense markets.
