USA Rare Earth Inc.'s stock soared 12.18% during intraday trading on Monday, marking a significant upward movement for the rare earths company.

The rally was driven by two major catalysts. First, the company announced a definitive agreement to acquire 100% of Brazilian rare earths miner Serra Verde Group for approximately $2.8 billion in a cash-and-stock deal. Serra Verde owns the Pela Ema mine, described as the only producer outside Asia capable of supplying all four critical magnetic rare earths at scale. The acquisition is a strategic move to build a vertically integrated rare earth supply chain and reduce Western reliance on Chinese supply.

Second, analyst firm Wedbush initiated coverage of USA Rare Earth with an Outperform rating and a $29 price target, providing additional positive sentiment. The analyst endorsement highlighted the company's strategy to build a comprehensive mine-to-magnet platform in the rare earth sector.
