United States Antimony Signals Aggressive Growth Ahead

United States Antimony Corp. ((UAMY)) has held its Q4 earnings call. Read on for the main highlights of the call.

United States Antimony Corp.’s latest earnings call struck a distinctly upbeat tone, underpinned by explosive top-line growth, expanding margins, a fortified balance sheet and a bulging contract backlog with U.S. government and industrial customers. Management acknowledged execution risks and near-term volatility, but framed them as timing and ramp issues rather than structural threats to the growth story.

Surging Revenue and Improving Margins

United States Antimony posted fiscal 2025 sales of $39.3 million, a 163% jump from the prior year as antimony demand and pricing strengthened alongside new contracts. Gross profit rose by $6.4 million, up 185% year over year, and gross margin improved from 23% to 25%, signaling better operating efficiency and pricing power.

Balance Sheet Strength and Liquidity Tailwind

Liquidity has transformed, with cash, U.S. treasuries and equity securities swelling to $91.3 million at year-end 2025 versus just $18.2 million in cash a year earlier. Working capital climbed to $44.6 million, an increase of $27.9 million, while net debt is essentially negligible at about $195,000, giving the company ample flexibility to fund growth.

Government and Industrial Contracts Build $354 Million Backlog

The company highlighted a sole-source Defense Logistics Agency contract that has been upgraded to $248 million over five years, with about $75 million of antimony ingot deliveries expected in fiscal 2026. A separate $106.7 million, five-year industrial antimony contract brings the total contract backlog to roughly $354 million, locking in multi-year demand.

Market Re-Rating and Institutional Adoption

The stock has rerated sharply, with the share price climbing from $1.78 to $5.02, a gain of 182%, and market capitalization leaping from $201 million to $703 million. Institutional holders rose from 48 to 222, trading volume averages about 15 million shares per day, and the uplisting to the NYSE main board has improved both visibility and liquidity.

Vertical Integration and Capacity Expansion

Management emphasized that the antimony division is now fully vertically integrated, positioning the company to capture more margin across the value chain. The Thompson Falls smelter expansion is expected to more than triple capacity, while planning and engineering for a hydromet facility in Idaho via a joint venture with Americas Gold and Silver is underway, supported by about $27 million in government funding.

Resource Additions and Strategic Assets

On the resource front, United States Antimony reported an inferred tungsten resource at Fostung in Ontario of 14,770,000 metric tons grading 0.17% WO3, or 54.17 million pounds, with a cited in-ground value of about $4.6 billion. The company also acquired a 10% stake in an Australian miner for $37.2 million and purchased the McDonald Creek antimony property for $1.3 million, which carries a historical report suggesting sizable in-situ value.

Bear River Zeolite’s Long-Life Upside

Bear River Zeolite was positioned as a long-duration asset, with a reported reserve life of roughly 400 years and water treatment already making up around 75% of its revenue. Recent moves to bulk logistics and new cattle-nutrition customers are expected to drive higher volumes and better margins in 2026, adding a steady, non-antimony growth leg.

Inventory Readiness for Contract Execution

To support its expanding contract commitments, the company increased antimony inventory from 78 tons to 465 tons by year-end 2025, with 17% sourced from its own Thompson Falls mine. Management noted that this inventory build creates a crucial supply buffer for the DLA and industrial contracts, with first pallet shipments to government customers nearing completion.

Wider Net Loss Driven by Noncash Costs

Despite strong revenue growth, the net loss widened from $1.7 million in 2024 to $4.3 million in 2025, a headline that may unsettle some investors. However, management stressed that $6.7 million of 2025 expenses were noncash, primarily stock-based compensation, versus $1.9 million a year earlier, meaning the underlying cash performance is notably stronger than GAAP earnings indicate.

Thompson Falls Expansion Delays

Execution risk surfaced at Thompson Falls, where the smelter expansion timeline slipped from December or January to May, a roughly five-month delay tied to contractor issues, pad redesign, weather and heat-exchanger lead times. As a result, management does not expect any financial contribution from the expansion in the first quarter of 2026, pushing some earnings power later into the year.

Alaska Seasonality and Permitting Frictions

In Alaska, permitting delays forced the company to acquire private patented claims and slowed the pace of planned exploration programs. Trenching and drilling were also interrupted by winter conditions, and management cautioned that some activities may now slide into the summer and fall of 2026, stretching out timelines for de-risking those assets.

Exploration Risks and Project Uncertainty

The call also flagged exploration disappointments, including the Iron Mask high-grade cobalt and nickel target, which appears to be cut off by a younger dike and will require additional follow-up. Several other projects remain at the exploration or bulk-sample stage and are not yet proven economic, underscoring that not every initiative will translate into commercial production.

Supply Chain and Geopolitical Exposure

Reliance on specialized equipment vendors has produced multi-month delays, with limited alternatives when bottlenecks occur, highlighting a capacity and timing risk that could recur. The company still procures antimony from multiple foreign suppliers across six countries, leaving it exposed to geopolitical and logistics shocks, including export restrictions from key producing regions.

Near-Term Earnings Volatility and Investment Uncertainty

Management warned that 2026 results will likely be “bumpy” from quarter to quarter as shipment timing, price swings and project sequencing drive fluctuations around the growth trend. The company’s 10% stake in Australian miner Larvotto Resources remains a passive holding, and executives offered no definitive strategy for monetizing or deepening that relationship, leaving the investment’s future impact uncertain.

Guidance and Growth Outlook

Looking ahead to fiscal 2026, United States Antimony guided to $125 million in revenue, with roughly $75 million expected from DLA antimony ingot deliveries under the expanded $248 million contract and supported by a $354 million total backlog. Management expects to stay minimally leveraged and cash-rich, complete the Thompson Falls expansion in May, bring the hydromet JV online within 12–18 months, and leverage 465 tons of built inventory, while reiterating that quarterly results will remain choppy even as the full-year target is pursued.

United States Antimony’s earnings call painted the picture of a small-cap miner rapidly scaling into a strategically important, vertically integrated supplier with strong institutional sponsorship. While delays, exploration risk and supply-chain exposure remain real, the combination of robust contract coverage, a strengthened balance sheet and planned capacity expansions has investors betting that the growth story still has room to run.
