MP Materials

Thesis

MP Materials is the most direct public play on American rare earth independence. It is the only fully integrated mine-to-magnet rare earth producer in the US, operating the Mountain Pass mine in California. The DoD invested $400M for a 15% equity stake, and the company announced a $1.25B '10X' magnet campus in February 2026 with 100% of output committed to the Pentagon. The geopolitical thesis is simple and powerful. China controls ~60% of rare earth mining and ~90% of processing. Any supply disruption, whether from trade war, Taiwan conflict, or embargo, would cripple Western defense and EV manufacturing. MP Materials is the primary hedge against this scenario. However, the valuation is extreme. At ~$50 and ~$9B market cap, MP trades at approximately 1,430x forward P/E. The stock prices in the geopolitical premium and then some. The magnet campus won't generate meaningful revenue until 2027-2028 at the earliest, creating a long gap between current valuation and revenue realization. USA Rare Earth (NASDAQ: USAR) offers earlier-stage exposure with a $3.1B government capital package but at a much smaller scale and higher risk profile.
