United States Antimony (UAMY) Q1 2026: Zeolite Shipments Surge 66% as Critical Minerals Platform Expands

United States Antimony’s first quarter marked a decisive shift from niche antimony producer to a multi-mineral, government-aligned critical minerals platform. Substantial operational investments and federal grants are fueling capacity and diversification, even as near-term margins absorb upfront costs and inventory build. With zeolite and antimony infrastructure scaling and new supply agreements in place, UAMY is positioned to capitalize on surging government and industrial demand in the back half of 2026.

Summary

  • Zeolite Demand Outpaces Infrastructure: Record monthly shipments and new customer wins are driving urgent capacity upgrades.
  • Antimony Platform Broadens: UAMY is leveraging government contracts and joint ventures to become the U.S. hub for critical minerals processing.
  • Back-Half Ramp Catalyzes 2026 Trajectory: Operational headwinds are set to reverse as new facilities and contracts activate in coming quarters.

Business Overview

United States Antimony Corporation (UAMY) is a vertically integrated miner, processor, and supplier of antimony, zeolite, tungsten, cobalt, and gold, with a growing focus on critical mineral supply chains for U.S. government and industrial customers. The company operates through two principal segments: antimony, used in defense and energy applications, and zeolite, a specialty mineral targeting animal nutrition and filtration markets. UAMY generates revenue by mining, processing, and selling these minerals, with an increasing share of sales tied to federal contracts, as well as new verticals in animal feed and industrial applications.

Performance Analysis

Q1 2026 results reflected a transitional phase as UAMY absorbed front-loaded costs to support its strategic ramp in both antimony and zeolite operations. Sales were essentially flat year-over-year, with the antimony segment down 2% and zeolite down 7%. Gross profit contracted sharply, primarily due to higher labor, factory, and freight costs, as the company built inventory and staffed for anticipated production growth.

Non-cash expenses and mark-to-market losses on equity holdings further pressured the bottom line, resulting in a sizable net loss. However, UAMY exited the quarter with a robust cash and securities position of $60.2 million, augmented by a $12.8 million federal grant and $48.6 million in equity proceeds post-quarter.

  • Zeolite Momentum Accelerates: March and April shipments broke all-time records, with April volumes 66% above target, signaling strong product-market fit in cattle nutrition.
  • Antimony Supply Chain Strengthens: Reliable monthly deliveries and new purification methods at the Madero smelter have doubled inventory, enabling consistent production and higher-quality output.
  • Capital Deployment Focused on Scale: Inventory rose to $22 million as UAMY prepares for a major second-half ramp, supported by government grants and minimal debt.

While Q1 margins reflected upfront investment, the operational groundwork is expected to drive step-change revenue and margin improvement as new capacity and contracts activate through 2026.

Strategic Positioning

1. Zeolite Platform Scaling for Cattle Nutrition

Bear River Zeolite (BRZ), zeolite business, is transitioning from a legacy industrial mineral operation to a focused, high-growth animal nutrition supplier. The launch of delivered pricing, expanded logistics, and new automation investments have enabled record shipment volumes, but also required significant upfront cost. Customer acquisition is accelerating, with two new cattle nutrition accounts added in the last two weeks of the quarter and April shipments up 66% versus target.

2. Antimony Supply Chain Integration and Expansion

UAMY is deepening its role as the sole U.S. government supplier of antimony, while building out a vertically integrated supply chain spanning mining, processing, and purification. The Thompson Falls expansion is staged to reach 80% capacity by mid-July, with new supply contracts and international partnerships (e.g., Bolivia) diversifying input sources. Hydrometallurgical technology, hydromet, is being developed to process lower-grade and higher-impurity feedstock, broadening the accessible resource base.

3. Multi-Mineral Diversification and Federal Alignment

UAMY’s ongoing pivot to tungsten, cobalt, and gold is directly aligned with federal critical mineral priorities. The $27 million Department of Defense grant, new applications totaling $274 million, and active engagement with multiple agencies illustrate the company’s centrality to U.S. supply chain reindustrialization. Resource reports indicate multi-billion dollar potential in tungsten, with the first North American production in decades targeted.

4. Institutionalization and Market Visibility

Institutional ownership is approaching 50%, up from primarily retail, as UAMY’s profile grows through uplisting, roadshows, and national media campaigns. The company is leveraging this visibility to attract strategic partners, broaden its investor base, and reinforce its role as a critical minerals leader.

Key Considerations

This quarter’s results reflect a deliberate, front-loaded investment strategy to position UAMY as a vertically integrated, multi-mineral supplier at the nexus of U.S. policy and industrial demand. The company’s ability to translate these investments into sustained revenue and margin growth will hinge on execution as new facilities and contracts ramp in the second half.

Key Considerations:

  • Zeolite Throughput Bottleneck: Surging demand is outstripping current infrastructure, requiring urgent automation and logistics upgrades to capture growth in animal nutrition.
  • Antimony Expansion Execution: Timely commissioning and scale-up of Thompson Falls and Raidersburg are critical to meeting government contract volumes and quality standards.
  • Federal Grant Milestone Risk: Ongoing access to federal funding is tied to project milestones, particularly for Alaska and hydromet initiatives.
  • Hydromet Technology Leverage: Success in Idaho and Bolivia could unlock new resource streams and third-party processing opportunities, but requires technical and operational follow-through.
  • Institutional Engagement Momentum: Deepening buy-in from funds and strategic partners underpins capital access and market credibility, but must be matched by operational delivery.

Risks

Execution risk remains elevated as UAMY brings multiple new facilities and supply agreements online in parallel, with potential for further cost overruns, commissioning delays, or supply chain disruptions. Federal grant disbursements are milestone-dependent, and any slippage in project timelines could impact liquidity and growth targets. Market risk persists around commodity price volatility, particularly for antimony and tungsten, and the company’s exposure to a concentrated set of government buyers.

Forward Outlook

For Q2 2026, UAMY expects:

  • Substantial ramp in zeolite shipments as infrastructure upgrades come online
  • Thompson Falls expansion to reach 80% operational capacity by mid-July

For full-year 2026, management maintained guidance:

  • $125 million in revenue, with $75 to $95 million expected from federal government antimony shipments

Management highlighted several factors that will determine the pace of the ramp:

  • Speed of equipment commissioning and workforce onboarding at new facilities
  • Ability to meet government delivery timelines and quality standards for antimony ingots

Takeaways

UAMY’s Q1 marks a pivotal inflection as the company transitions from legacy antimony miner to a diversified, federally aligned critical minerals platform.

  • Operational Foundation Set for Back-Half Acceleration: Upfront investments in inventory, logistics, and capacity position UAMY for a material revenue and margin expansion as new contracts and segments scale.
  • Federal Alignment Drives Visibility and Capital Access: Grant wins, uplisting, and institutional inflows reinforce UAMY’s strategic relevance, but execution against project milestones remains critical.
  • Execution on Zeolite and Antimony Ramps Will Determine 2026 Trajectory: Investors should watch for evidence of throughput gains, government shipment volumes, and progress on hydromet and diversification initiatives in the coming quarters.

Conclusion

United States Antimony delivered a transitional quarter defined by aggressive investment and operational groundwork, positioning the company for a step-change in scale and relevance as critical minerals demand intensifies. The second half of 2026 will be the proving ground for UAMY’s multi-mineral, government-aligned strategy, with execution on new supply, processing, and market initiatives as the key watchpoints for investors.
