Is UAMY a Buy or a Sell? The Bull and Bear Case (2026)

That depends on which case you find more convincing, and both are on this page. The bull case rests on The tripled Montana smelter, with revenue (ttm) at ~$36.4M. The bear case rests on the antimony price cycle dominates everything. Analysts covering it are spread from $9.00 to $13.50, which is itself a signal that this is genuinely contested. If you believe the thesis, the real questions become sizing and overlap rather than timing. Walnut is not an investment adviser and this is not a recommendation.

Nobody can answer that for you, and the honest version of the question is narrower: has anything changed in the reason you bought it? The bear case on this page is the place to check. The antimony price cycle dominates everything. If that risk is what you were worried about and it is now playing out, that is a real signal. If the price simply fell while the thesis held, that is a different situation entirely. The most pessimistic published target is $9.00, +73.1% from the $5.20 price, which is one analyst's downside case rather than a floor. Walnut is not an investment adviser.

The tripled Montana smelter. The Thompson Falls expansion cost ~$39M, was substantially completed during the second quarter of 2026, and is expected to more than triple the facility's antimony processing capacity. The most optimistic analyst target on UAMY is $13.50, +159.6% from the $5.20 price. That figure is only reachable if this thesis works close to its best case.

The antimony price cycle dominates everything. European assessments peaked near ~$59,750 per tonne in July 2025 and had fallen to roughly ~$23,000 by mid-2026, which is why UAMY shares trade near ~$5.20 against a 52-week range of ~$4.14 to ~$19.71. Dilution has been heavy: shares outstanding went from ~108 million in mid-2024 to ~150.5 million at June 2026, including ~$49.1M of net equity issuance in the first half of 2026 at an average of ~$11.56 per share, well above the current quote. Share-based compensation of ~$7.7M in six months is large against ~$14.7M of revenue, and reported net income now swings on the mark-to-market value of the Larvotto stake rather than on operations. Customer concentration and Mexican operating exposure are also disclosed. The most pessimistic published target is $9.00, +73.1% from the current price, which is roughly what the stock is worth if these risks bite rather than the drivers.

The only fully integrated antimony miner, smelter and refiner outside China and Russia, with Montana and Mexico smelters plus an Idaho zeolite mine.

Decide that in advance, because it is far harder to think clearly once a position is moving against you. The concrete tripwires here: the driver behind the bull case (The tripled Montana smelter) stalling in the reported numbers rather than in the narrative, the risk above (the antimony price cycle dominates everything) turning from a possibility into a reported fact, or the position growing large enough that a bad outcome would matter to your whole portfolio regardless of who is right.

It mines, buys and processes antimony ore into finished products including antimony oxide, metal ingots and trisulfide, at a smelter in Thompson Falls, Montana and a second smelter in Mexico. It also mines and sells zeolite from Bear River Zeolite in Preston, Idaho. The company describes itself as the only fully integrated antimony operation outside China and Russia. Antimony sits on the U.S. Critical Minerals List because of its use in flame retardants, ammunition primers and batteries.

The share price tracks the antimony price, which spiked after China imposed export controls in late 2024 and then corrected hard. European assessments went from roughly ~$15,000 to ~$18,000 per tonne before the controls, to a peak near ~$59,750 in July 2025, back to about ~$23,000 by mid-2026. UAMY's own realized price fell ~52% year over year to ~$13.70 per pound in the second quarter of 2026, and the stock now trades near ~$5.20 against a 52-week high of ~$19.71.

Not from operations. The company reported a ~$7.0M operating loss in the second quarter of 2026 and a ~$14.5M operating loss for the first half. Second-quarter net income of ~$0.1M came almost entirely from a ~$6.8M unrealized gain on the company's shareholding in Larvotto Resources plus ~$0.4M of investment income. Over the trailing twelve months the net loss is ~$16.3M on ~$36.4M of revenue.
