About
MP Materials Corp. is the only fully integrated rare earth mining and processing company in the United States, headquartered in Las Vegas, Nevada. The company operates the Mountain Pass rare earth mine and processing facility in San Bernardino County, California — the only rare earth mining operation of scale in the Western Hemisphere. Founded in 2017 and going public via SPAC in 2020, MP Materials is strategically critical to US efforts to secure domestic supply of rare earth elements, particularly neodymium and praseodymium (NdFeB), which are essential for the permanent magnets used in EV motors, wind turbines, industrial robots, and MRI machines.
National aggregate (crushed stone) producer with $6.6B FY2024 revenue; permitting barriers create durable pricing power; IIJA infrastructure spending multi-year tailwind; competes with Vulcan Materials.
About
Martin Marietta Materials is one of the nation's leading suppliers of building materials, including aggregates (crushed stone, sand, and gravel), cement, ready-mixed concrete, and asphalt—the essential bulk commodities upon which roads, bridges, buildings, and infrastructure are built. Spun off from Martin Marietta Corporation in 1993 and headquartered in Raleigh, North Carolina, the company trades on NYSE (MLM) and generated approximately $6.6 billion in net revenues for FY2024 under CEO Ward Nye, who has led Martin Marietta since 2010 and executed a long-term geographic expansion strategy that has doubled the company's revenue and market capitalization through acquisitions and organic pricing growth. The 2022 acquisition of Lehigh Hanson's Western operations from Heidelberg Materials for $2.3 billion added major aggregate reserves in Texas and Colorado, reinforcing Martin Marietta's Sun Belt and Rocky Mountain footprint.
