Shares of USA Rare Earth Inc. climbed more than 8% in early Monday trading on April 20, 2026, rising $1.60 to $21.55 after the company announced a major $2.8 billion deal to acquire Serra Verde Group, a move that instantly expands its access to producing mines and all four key magnetic rare earth elements while strengthening its position in the global supply chain.

The acquisition, unveiled early Monday, positions USA Rare Earth as a formidable player aiming to challenge China's dominance in rare earths. Serra Verde operates a mine in Brazil that currently produces all four magnetic rare earths — neodymium, praseodymium, dysprosium and terbium — essential for high-performance permanent magnets used in electric vehicles, wind turbines, defense systems and advanced electronics.
