UAMY Surges 5.31% on Back of Thompson Falls Expansion and 2026 Outlook Optimism

United States Antimony (NYSEAmerican:UAMY) surged 5.31% in pre-market trading on Dec. 26, 2025, extending its rally to a fourth consecutive session amid investor optimism over its 2026 outlook. The move follows recent statements from company chairman Gary Evans, who highlighted the completion of the Thompson Falls expansion as a catalyst for growth in the coming year.

Third-quarter results showed a 238% year-on-year revenue increase to $8.7 million, though net losses widened to $4.78 million, up 556% from the prior year. The pre-market gains align with seasonal portfolio rebalancing by institutional investors, who often adjust holdings before reporting periods to emphasize strong performers like UAMY.

As the sole U.S. antimony smelter operator, the company’s strategic position in critical minerals markets remains a focal point for traders. Analysts note the stock’s recent momentum reflects a combination of operational progress and year-end liquidity dynamics in the sector.

Investor positioning in small-cap industrial metals producers has gained momentum as year-end tax-loss harvesting and portfolio reallocation create additional tailwinds for names like UAMY. Market participants are also monitoring the impact of broader inflation metrics and commodity price trends on the sector's valuation.
