Shares of United States Antimony (UAMY) tumbled 6.82% in trading on Wednesday, following the release of disappointing third-quarter earnings results and lowered full-year guidance. The mining company's financial performance fell significantly short of analyst expectations, triggering a sell-off in the stock.

United States Antimony reported a quarterly loss of $0.04 per share, missing the analyst consensus estimate of a $0.02 profit by a wide margin. This represents a 300% increase in losses compared to the same period last year. On the revenue front, the company also underperformed, with quarterly sales of $8.702 million falling short of the projected $12.860 million by 32.33%. Despite the revenue figure marking a substantial 259.44% increase year-over-year, the widening losses raised concerns about the company's cost management and operational efficiency.

Adding to investor worries, United States Antimony narrowed its full-year 2025 revenue guidance to a range of $40 million to $43 million, below the analyst expectation of $46.4 million. This downward revision in guidance, coupled with the earnings miss, likely contributed to the sharp decline in the stock price. However, the company maintained its 2026 revenue guidance of $125 million, which is above the analyst consensus of $116.1 million, providing a glimmer of hope for long-term growth prospects. As investors digest these mixed signals, the market will be closely watching United States Antimony's ability to address its near-term challenges and deliver on its future projections.
