$UAMY: The Only Western Antimony Smelter Ramping Now

In the summer of 2024, China’s Ministry of Commerce announced export controls on antimony. Not a tariff. A ban. The dominant supplier of a metal that goes into military tracer rounds, night vision equipment, flame retardants for jet interiors, and semiconductor manufacturing simply removed itself from Western supply chains. No warning, no phase in, no alternative ready to step in. The price of antimony roughly tripled inside twelve months.

There is exactly one fully integrated antimony smelter in the Western Hemisphere. It sits in Thompson Falls, Montana, and it belongs to United States Antimony Corporation, $UAMY. A company that was doing $15M in annual revenue two years ago just signed a $245M contract with the Defense Logistics Agency, completed its first deliveries under that contract, and is guiding to $125M in revenue for the current fiscal year.

The stock is at $5.07 as of July 31. Four analysts covering it carry an average price target of $13.06. The Q1 2026 quarter was a mess, operationally, and the market has repriced accordingly from a high of $19.66 this cycle. What has not changed is the structural position: China stays out, UAMY is the only game in town for U.S. defense procurement, and the new nine furnace smelter is now commissioned and filling orders.

Our thesis is simple. The market is treating UAMY as a busted ramp story because Q1 missed badly. We think Q1 was a feedstock problem, not a structural one, and that Q2 earnings, due roughly August 7 to 11, will begin to show the volume line the $125M guidance requires. If it does, estimates move up hard from a very low base. If it does not, the guidance fails and the risks we lay out below become the story.

The 60 second version

• United States Antimony Corporation is the only vertically integrated antimony smelter in the Western Hemisphere, mining, milling, smelting, and selling antimony products and zeolite from facilities in Montana and Mexico.
• China’s 2024 export ban on antimony removed the dominant global supplier permanently from Western markets, creating a structural domestic monopoly for UAMY in U.S. defense procurement.
• $57.3M in cumulative DLA orders as of July 1, 2026, against a $245M IDIQ contract ceiling, with first deliveries confirmed completed, is the first hard proof that the revenue ramp is real rather than contracted but not shipped.
• Catalyst: Q2 2026 earnings, projected August 7 to 11, is the first quarter with the new Thompson Falls smelter and Radersburg flotation mill both fully operational and DLA deliveries on the revenue line. Management FY2026 guidance is $125M, roughly 3.2 times FY2025 revenue of $39.3M.
• Main risk: Q1 2026 revenue came in at $6.8M against a consensus of $14.83M due to feedstock disruptions; if the smelter does not reach 300 to 400 tons per month throughput by Q3, the full year number is mathematically unreachable and a dilutive raise follows.
• Market cap approximately $750M at $5.07 per share on 148.19M shares outstanding; short interest roughly 18.95% of float, or about 26.5M shares short.

The shift

Antimony sits in an odd category among critical minerals. It is not rare in the geological sense, but viable deposits that can be economically processed are concentrated, and the global refining capacity has been almost entirely located in China for the past two decades. At peak, China supplied somewhere above 60% of global refined antimony output. Western mining companies, including UAMY in its earlier incarnation, had largely been squeezed out by lower cost Chinese product.

The export ban changed that calculation permanently, and the operative word is permanently. This was not a trade skirmish that ends with a negotiated agreement. China classified antimony alongside gallium and germanium as a strategic export controlled material in the context of an escalating technology and defense competition with the United States. The structural incentive to lift that ban does not exist in the current geopolitical environment, and U.S. policy has responded with the Defense Production Act designations, stockpile building contracts through the DLA, and Department of Defense grant funding that partially financed UAMY’s smelter expansion.

The price signal arrived fast. Antimony trioxide spot prices that sat below $5,000 per metric ton in early 2024 ran to well above $15,000 per metric ton through 2025. UAMY’s FY2025 revenue grew 163% year over year to $39.3M, and management attributed the single largest driver to a 230% spike in the average realized antimony price rather than volume alone. Volume growth lagged price growth. The whole point of the current expansion is to close that gap.

Where the sector sits on the adoption curve: we are past the demand inflection and into the supply response phase. The question is no longer whether U.S. defense and industrial buyers need domestic antimony. They demonstrably do, the DLA contract proves it, and the DoW grant money proves the government is paying to solve it. The question is purely execution: can UAMY build enough throughput fast enough, and with sufficient feedstock security, to fill the orders that are already signed.

The company

United States Antimony was founded in 1968 and spent most of its history as a sleepy micro cap miner operating the Thompson Falls antimony mine in Montana and a processing facility in Mexico. The business was real but small. Revenues sat in the low single digit millions for years, and the company was better known among small cap resource investors than anyone else.

What the company has today is structurally different. The Montana operations now include a newly commissioned smelter at Thompson Falls with nine gas fired furnaces, which management says represents a 300 to 400% capacity lift over the prior configuration. The Radersburg flotation mill in Montana is also commissioned and operational as of Q2 2026, allowing the company to process lower grade domestic ore that was previously uneconomic. In Mexico, the Madero smelter continues to process Bolivian concentrate under an existing offtake arrangement, providing a second production node. The company sells antimony oxide, antimony ingot, and antimony trisulfide, which is the form used in military pyrotechnic applications, directly to the DLA and to industrial flame retardant buyers.

CEO Gary Evans has been running the operational expansion alongside what appears to be an active government relations effort. The company has received $12.8M of a $27M Department of Defense grant award, with the remaining $14.2M to come, partially funding the smelter build out. Evans confirmed on July 1 that after completing first deliveries under the DLA contract, the company had already received larger follow on government orders, a specific detail from the press release that has not yet appeared in any analyst model we have seen.

One line from the Q1 2026 earnings call transcript worth noting: the Bolivian feedstock disruption that wrecked Q1 revenue was attributed specifically to a diesel shortage in Bolivia connected to the Strait of Hormuz conflict affecting fuel supply chains into South America. That is an unusual and specific supply chain dependency. We do not know the exact volume or pricing terms of the Bolivian concentrate offtake contract, and that matters for modeling feedstock security going forward.

The numbers and what the street expects

Start with the full year. FY2025 revenue was $39.3M, up from $15M in FY2024, an increase of 163% in a single year. The price of antimony did most of the work. Management guided FY2026 revenue at $125M on May 14, reaffirming that number after the Q1 miss, which itself tells you something about their confidence in the back half. Four analysts on S&P Global and Seeking Alpha carry a consensus FY2026 revenue estimate of $124.84M, essentially in line with guidance. The consensus EPS estimate is $0.14.

The math of hitting $125M is where the stress shows. Q1 revenue was $6.8M. Q2 consensus per ChartMill sits at roughly $22.13M, which was revised down 1.36% over the prior three months following the Q1 miss. Even if Q2 hits $22M, the total for H1 lands around $29M, leaving roughly $96M needed across Q3 and Q4, or about $48M per quarter. That is more than the entire FY2025 revenue in a single quarter. It is achievable only if the Thompson Falls smelter reaches and sustains 300 to 400 metric tons per month throughput while the DLA delivery schedule front loads H2 volume.

On the balance sheet, UAMY had $118.9M in cash and marketable securities at March 31, 2026, against essentially zero debt ($265K). Operating cash outflow was $(8.3)M in Q1, and the net loss was $(11.3)M, of which $(9.3)M was noncash, primarily depreciation and non cash compensation, which are real costs but do not drain the cash account. The company raised roughly $110M through ATM and direct offerings in 2025, and added another $48.6M in post Q1 equity issuances. Dilution has been aggressive. The share count has roughly doubled over the past two years.

Gross margin compressed sharply, from 34% in Q1 2025 to 16% in Q1 2026. That compression is the smelter ramp in accounting form: elevated fixed costs against low initial throughput, with Bolivian feedstock shortfalls limiting recoverable volume. If throughput doubles in Q2 and Q3 as the new furnaces fill, the fixed cost base spreads across more units and gross margin recovers toward the 30% range management has implied. That margin recovery is not in the Q2 consensus number. A beat on both revenue and margin would be a double surprise.

All four analysts rate the stock Strong Buy. The average price target is $13.06 per share against a current price of $5.07, per ChartMill data. HC Wainwright carries a target of $11.75 and B. Riley is in the $13 to $14 range. That target spread is telling: the analysts are not debating the strategic value of the asset, they are debating the execution timeline. Argus and Alliance Global Partners round out the coverage, with Alliance carrying a Buy rating. For a company of this profile, four analysts is thin, but it is not zero, and thin coverage in a name with a genuine catalyst is the setup we look for.

The gap between the guidance and where consensus sits on a quarterly basis is the potential trade. Guidance implies a step change in Q2 and sustained volume through Q4. Consensus has modeled a much smoother, lower trajectory. A Q2 revenue print materially above $22M forces every model to reset. The July 1 update confirming first deliveries completed and larger follow on orders already received is the most important data point since the DLA contract itself, and it does not appear to have moved the consensus estimate.

Why it wins

The moat here is geographic, regulatory, and metallurgical simultaneously. Building a new antimony smelter in the United States means permitting under federal and state environmental law, securing a feedstock supply chain across international borders, and qualifying the output for defense specifications that require documented domestic origin. That process takes years under ideal conditions. Under current federal permitting timelines, it takes longer.

The DLA contract is not simply a purchase order. It is a qualification. Once a supplier is qualified as the domestic source for a defense critical material, the switching cost for the buyer is not just price, it is an entire re qualification process. The $27M in DoW grant funding effectively means the U.S. government co invested in UAMY’s capacity expansion. That does not get undone by a competitor appearing next quarter.

The tungsten expansion adds a second layer. UAMY is positioning itself as the first domestic tungsten producer in roughly a decade, with tungsten facing its own China supply concentration problem. We do not have verified capital cost or timeline data on the tungsten project, so we are not putting any revenue in our thinking from it, but the strategic logic is consistent: one company, multiple critical minerals, one government customer that cannot buy from China.

Short interest at roughly 18.95% of the float, or approximately 26.5M shares, on a stock with 9 to 12 million shares of average daily volume, creates mechanical squeeze potential if Q2 is a substantial beat. We do not count on squeezes, they are not a thesis, but they compress the time between a positive catalyst and a price response.

What could go wrong

Q1 happened. That is the starting point for the bear case, and it deserves its full weight. Revenue of $6.8M against a consensus of $14.83M is not a small miss. It is a 54% miss, in a quarter where the new smelter was supposedly coming online. The Bolivian diesel shortage explanation is specific and credible, but it also reveals that UAMY’s production is dependent on imported concentrate from a country where fuel supply can be disrupted by geopolitical events halfway around the world. That is a supply chain risk that does not disappear because the furnaces are commissioned.

If Q2 revenue comes in near or below the revised $22M consensus, the $125M full year number is mathematically over. Management would either cut guidance dramatically or attempt to raise equity to fund operations through a longer ramp, repeating the dilution pattern of 2025. The share count has already roughly doubled in two years. Another large raise at current prices would punish anyone who bought at $5.

The gross margin compression tells a second story. At 16% gross margin in Q1, on $6.8M of revenue, the company is losing money on operations while the smelter runs below rated capacity. Every month that throughput stays below target costs real money. The cash balance of $118.9M is substantial, and at the Q1 burn rate the company is not in immediate distress, but the burn accelerates if capital spending continues and revenue stays low.

There is also the stock’s history to consider. UAMY traded as high as $19.66 in this cycle and is now at $5.07. Investors who bought the China ban story at peak prices have been badly burned. The current shareholders include a meaningful short interest base betting that the execution problems are structural rather than temporary. They may be right. We think the feedstock explanation for Q1 is the correct one, but we hold that view with less than full conviction, and Q2 will tell us whether we are.

The investment thesis

China’s export ban created a permanent domestic monopoly for UAMY in U.S. defense antimony procurement, and the market is currently pricing the company as though the Q1 execution stumble reflects the terminal state of the business rather than a feedstock disruption in a ramp quarter.

What has to be true for this to work: the Thompson Falls smelter reaches 300 to 400 metric tons per month throughput in Q2 or Q3, the Bolivian feedstock flows consistently now that the diesel disruption has passed, and the DLA follows through on the larger orders that the CEO confirmed receiving after first deliveries. None of those things are guaranteed. All of them are consistent with what the company reported on July 1.

What the market appears to believe instead: that Q1 is evidence of a persistent capability gap, that guidance will be cut, and that further dilution is the most likely outcome. The four analyst consensus of $124.84M in FY2026 revenue nominally agrees with management, but the quarterly model that gets there implies a gradual ramp rather than the step change in H2 that the math actually requires. No analyst we have found has adjusted their quarterly estimate to reflect the July 1 confirmation of completed first deliveries and larger follow on orders received.

The specific gap we are watching: the street is modeling roughly $22M for Q2 and a similar run rate into Q3. Management guidance requires roughly $48M per quarter in H2. A Q2 print above $30M, which would still be below the H2 pace required, forces a fundamental revision to the quarterly model and likely triggers upward revisions across all four analysts simultaneously, from a starting coverage base of zero institutional consensus on the H2 step change.

This is a name to hold through the Q2 earnings catalyst, not to enter after it. The earnings report, expected around August 7 to 11, is the single event that either validates or breaks the thesis on the timeline that matters. If Q2 revenue is in line with the prior consensus and the smelter throughput data does not show a material ramp, the thesis fails. The falsification is simple: Q2 revenue below $25M, or any downward revision to full year guidance, tells you the ramp is not happening on the schedule the thesis requires.

What we are watching

• Q2 2026 earnings release, projected August 7 to 11, 2026: revenue versus $22.13M consensus, smelter throughput disclosed in metric tons per month, gross margin recovery from the Q1 16% trough, and any update to FY2026 guidance.
• DLA cumulative order update, expected with or shortly after Q2 results: the number was $57.3M as of July 1 against a $245M ceiling; progress toward $100M cumulative would confirm the delivery schedule is on track.
• Bolivian feedstock confirmation, Q2 call or 10-Q, expected August to September 2026: any disclosure about current concentrate shipment status and whether the diesel related disruption has fully resolved.
• Department of Defense remaining grant disbursement: $14.2M of the $27M DoW grant remains undisbursed as of the last filing; timing of that receipt affects the cash position and the dilution pressure.
• Q3 2026 earnings, projected November 2026: the quarter where the $48M per quarter H2 pace either shows up or does not, making this the harder and more definitive test of the full year thesis.

The bottom line

China handed UAMY a structural monopoly it could not have built on its own. The Defense Logistics Agency handed it a $245M contract and the U.S. government handed it $27M in grant funding to build the capacity to fill it. Those facts are not in dispute. What is in dispute is whether the company can execute the operational ramp at the pace the guidance requires, after a Q1 that went badly enough to cut the stock from the high teens to five dollars.

The July 1 update, completed first deliveries and larger follow on orders already received, is either the first data point in the confirmation of that ramp or a one time event that precedes another operational stumble. Q2 earnings resolves that ambiguity more than anything else we could track. We think the feedstock disruption was real, specific, and temporary, which makes Q2 the first clean quarter and therefore the quarter that matters most for this thesis.

The single thing that would change our mind entirely: a Q2 revenue print below $25M accompanied by any downward revision to FY2026 guidance. That combination would signal that the constraint is not Bolivian diesel but something deeper in the metallurgical process or the DLA delivery schedule, and the $125M path would be gone. Everything else, margin, cash burn, dilution pace, follows from that revenue number. Watch for it.

Not financial advice.

The setup

UAMY is in a clear downtrend. At 5.66, the stock sits 19.3% below its 50 day average and 30.4% below its 200 day average, with the 50 already crossed beneath the 200. That is a bearish stack across all three time frames. The price is near the floor of its 52 week range, sitting at just 19% of that range and 67.6% below the 52 week high. The recent slide is steep: down 22% over one month, 51.8% over three months, and 28% over six months, with three month relative strength lagging the broad market by 57.3 points. Volume has been running below normal at 0.66 times the 50 day average, which means the selling has not required heavy participation to push the stock down. RSI at 41 is not yet in deeply oversold territory. The average true range of 8.7% of price signals that daily swings are wide, so even routine fluctuations carry real dollar cost.

The historical base rate on this ticker covers 181 prior days when UAMY sat in a comparable technical position. In those instances the stock was higher one month later only 24% of the time, with a median one month move of negative 5.7%. At the quarter mark the median move was flat at 0.0% and the stock was higher just 49% of the time, though the range of quarterly outcomes was very wide, from negative 37.8% to positive 79.7%. The sample is reasonably sized at 181 observations, but it comes from a single small and volatile ticker, so it reflects one company’s particular history rather than anything universal. The base rate is not a forecast. What it does record honestly is that stocks sitting where UAMY sits now, on this ticker, have more often continued lower over the near term than recovered.
