Antimonio de los Estados Unidos (UAMY) sube 5,31% con grandes contratos y expansión.

United States Antimony (UAMY) surged 5.3068% in pre-market trading on December 26, 2025, driven by a major contractual win and operational expansion. The company secured a five-year, sole-source contract with the U.S. Defense Logistics Agency for antimony metal ingots valued at up to $245 million, alongside a $106.7 million commercial supply agreement for antimony trioxide. These agreements position the firm as a critical supplier for defense, flame-retardant, and battery applications, aligning with broader efforts to reduce foreign mineral dependencies.

Complementing the contract awards, United States Antimony is expanding its Montana smelter capacity sixfold to meet growing demand. This infrastructure boost directly supports the execution of both government and commercial commitments, though challenges such as permitting delays and feedstock quality remain key execution risks.

The dual focus on domestic supply chain resilience and high-margin, long-term contracts has sharpened investor focus on the company’s ability to scale operations without compromising compliance or efficiency.

The stock’s pre-market rally reflects optimism about the firm’s strategic alignment with U.S. policy priorities and its potential to secure recurring revenue streams. However, analysts caution that the success of these contracts hinges on consistent ore quality and operational execution, particularly as the company scales its production capacity. The expansion also introduces near-term capital intensity, which could test liquidity if permitting or supply constraints persist.

The company’s long-term positioning within critical supply chains remains a compelling narrative, but execution clarity will be essential to validate the aggressive revenue potential outlined in the recent agreements. Investors are advised to monitor key operational metrics and permitting updates as critical indicators of progress.
