United States Antimony Corp (UAMY) experienced a significant 24-hour plunge of 5.75% on Thursday, as the stock came under heavy selling pressure following the release of its first-quarter financial results.

The sharp decline was driven by the company reporting worse-than-expected earnings for the quarter. United States Antimony posted a quarterly loss of $0.08 per diluted share, which was significantly worse than the FactSet consensus estimate of a $0.02 loss. Revenue also fell short of expectations, coming in at $6.8 million compared to analyst estimates of $14.8 million, and representing a decline from the $7.0 million reported in the same period a year earlier.

Despite the weak first-quarter performance, the company reiterated its full-year 2026 gross revenue guidance of $125 million, which is roughly in line with analyst expectations of $124.8 million. The substantial earnings and revenue miss for Q1, however, appears to have been the primary catalyst for the stock's sharp intraday decline.
