MP Materials Wins GM Magnet Qualification-but $99/kg NdPr Pricing and Q3 Earnings Reveal a More Complicated Investment Story

Highlights

• GM completed qualification of MP Materials' U.S.-made NdFeB magnets, with saleable deliveries expected in Q4 2026
• Q3 revenue surged 176% to $147.7M, but a $31.6M one-time SEG+ specialty sale accounted for 21% of that figure
• NdPr realized pricing reached ~$99/kg, though the blended rate includes oxide, metal, and intercompany sales
• Magnetics segment revenue fell 15% to $18.6M and adjusted EBITDA dropped 44%, signaling the magnet gap remains unresolved
• Nine-month capex hit $420M and cash declined ~$492M, raising questions about capital efficiency ahead of a 2028–2030 profitability target
