DALLAS, TX / ACCESS Newswire / August 11, 2026 / United States Antimony Corporation ("USAC," "US Antimony Corporation," or the "Company") (NYSE:UAMY)(NYSE Texas:UAMY), a leading producer and processor of antimony, zeolite, and other critical minerals, and the only fully integrated antimony company in the world outside of China and Russia, today reported its financial and operating results for the second quarter and six months ended June 30, 2026.

Second Quarter 2026 Highlights

• Revenue of $7.9 million, compared to revenue of $10.5 million in the 2025 quarter.

• Gross profit of $0.6 million (7% gross margin), compared to $2.8 million (27% gross margin) in the 2025 quarter.

• Operating loss of $7.0 million, including $3.4 million of net non-cash expense items compared to break-even operating results in the 2025 quarter.

• Net income of $0.1 million, compared to net income of $0.2 million in the 2025 quarter. Operating loss in second quarter of 2026 was more than offset by $6.8 million of unrealized gain from investment in equity securities plus $0.4 million of interest income.

• Delivered the first two shipments of approximately 82,000 pounds of antimony metal ingots under the Company's contract with the DLA in June 2026. Because these shipments were formally accepted by the DLA in July 2026, approximately $2.6 million is expected to be recognized as third-quarter 2026 revenue.

• Zeolite segment revenue grew 110% year-over-year to $1.9 million, with tons sold up 114% year-over-year to 6,609 tons, driven by continued penetration into the cattle market and expanded distribution across the Company's traditional industrial markets.

• Invested $22.8 million gross in capital expenditures during the first six months of 2026, primarily to substantially complete the Thompson Falls expansion, acquire the flotation facility (midstream) located in Radersburg, Montana, and fund investments including additional critical mineral rights acquisitions.

• The Thompson Falls expansion was partially funded by a $12.8 million payment received in April 2026 for milestones achieved under the Defense Production Act Title III grant award from the U.S. Department of War (the "DoW") which reduced the Company's net cash outlay for these capital expenditures.

• Commissioned the flotation facility (midstream) located in Radersburg, Montana and substantially completed the Thompson Falls, Montana expansion, further strengthening the Company's vertically integrated domestic antimony production platform.

• Generated $49.1 million of net proceeds from equity issuances during the first six months of 2026, strengthening the Company's balance sheet and ending June 30, 2026, with $62.2 million of (cash plus U.S. Treasury securities held to maturity, plus a $43.2 million strategic equity investment in Larvotto Resources Limited.

• Working capital doubled to $70.0 million on June 30, 2026 from $35.0 million at March 31, 2026, primarily driven by the equity issuances, providing meaningful operating and capital runway to support the Company's growth investments.

• Continued expansion of the Company's domestic critical minerals platform through strategic mining claim acquisitions located in Alaska (Nolan Creek and Fairbanks District) and Montana, and advanced the Company's Tungsten evaluation through the filing in April 2026 of a Technical Report Summary on the Fostung tungsten project in Ontario, Canada.

• Mark-to-market value of the Company's strategic investment in Larvotto Resources Limited increased to USD $43.2 million at June 30, 2026 (USD $46.7 million based on the closing market price on August 10, 2026), reflecting continued appreciation of the Company's critical minerals investment portfolio.

Strategic Overview

During the second quarter of 2026, the Company continued to advance its strategic focus of building a fully integrated critical minerals operation supporting U.S. national security and supply chain resiliency. Key accomplishments during the quarter included delivering the first two shipments under the Company's contract with the DLA, receiving $12.8 million of funding under the Department of War Title III grant program, advancing the Thompson Falls expansion toward full operational status, adding a key processing capability through the acquisition and upgrading of the Radersburg processing facility including the addition of a lab, strengthening the Company's balance sheet through approximately $49.1 million of net equity proceeds during the first six months of 2026, and continuing to expand the Company's domestic mining and processing platform across Montana, Alaska, and Canada. (April 2026 filing of a Technical Report Summary on the Company's Fostung tungsten project in Ontario.) In addition, the Company's Zeolite segment continued its strong growth trajectory during the quarter, with revenue up 110% year-over-year, while the Company's strategic investment in Larvotto Resources Limited appreciated in value. Additionally, USAC announced its new joint venture with Americas Gold and Silver to build a state-of-the-art hydromet processing facility in Idaho. Collectively, these accomplishments have further established the operational foundation for the Company's next phase of growth by enabling increased production, expanding sales to both the U.S. government and commercial customers, greater utilization of its integrated processing platform, and improved financial performance during the second half of 2026.

Second Quarter 2026 Financial Results

Second quarter 2026 revenues were $7.9 million, compared to $10.5 million in the second quarter of 2025. Antimony segment revenues were $5.9 million, compared to $9.6 million in the prior-year period. While antimony pounds sold increased approximately 26% to 428,425 pounds from 340,305 pounds, average selling prices declined approximately 52% to $13.70 per pound from $28.32 per pound. The price decline reflects the impact of lower market prices for antimony compared to the stronger pricing environment experienced in the second quarter of 2025. Average cost per pound also declined approximately 33% to $13.34 from $19.85, partially mitigating the impact of lower selling prices.

Cost of revenues decreased to $7.3 million from $7.7 million in the prior-year period; however, gross profit declined to $0.6 million from $2.8 million due to the significant decline in antimony selling prices. Gross margin was approximately 7%, compared to 27% in the second quarter of 2025. During June 2026, the Company completed its first two shipments totaling approximately 82,000 pounds of antimony metal ingots under its contract with the DLA. Because these shipments were not formally accepted by the DLA until July 2026, no second quarter 2026 revenue was recognized; approximately $2.6 million is expected to be recognized as revenue in the third quarter of 2026.

Zeolite revenue increased to $1.9 million from $0.9 million in the prior-year period, driven primarily by a 114% increase in tons sold to 6,609 tons from 3,084 tons. The increase reflects the Company's expanded sales efforts, including continued penetration into the cattle market and growth in its traditional industrial markets. Zeolite gross profit increased to $0.4 million from $0.1 million, benefiting from higher sales volumes and lower average production costs.

The Company's inventory has grown to $21.6 million as of June 30, 2026, compared to $12.5 million as of December 31, 2025 and $6.8 million as of June 30, 2025. The inventory consists of both material sourced from third-party suppliers and ore mined from the Company's Stibnite Hill mining claims. The inventory buildup reflects the Company's strategic investment in antimony feedstock that will support the anticipated production growth for both our commercial and DLA customer delivery time tables.

Operating expenses were $7.6 million in the second quarter of 2026, compared to $2.8 million in the prior-year period. The increase primarily reflects higher non-cash share-based compensation, increased salaries and employee benefits associated with the Company's expanded leadership team and operational infrastructure, and higher professional fees supporting the Company's strategic growth initiatives.

The Company reported an operating loss of $7.0 million, compared to essentially break-even operating results in the prior year period. Net income was $0.1 million, compared to $0.2 million in the second quarter of 2025. Second quarter 2026 results included an unrealized gain of approximately $6.8 million on the Company's investment in Larvotto Resources Limited, which substantially offset the operating loss for the quarter. The operating loss includes approximately $3.4 million of net non-cash items, comprised principally of $2.9 million of share-based compensation expense and $0.5 million of depreciation and amortization.

Liquidity and Capital Resources

As of June 30, 2026, the Company had cash and cash equivalents of $41.4 million and investments in U.S. Treasury securities held to maturity of $20.7 million, compared to $30.5 million and $20.4 million, respectively, at December 31, 2025. The $11.6 million increase in cash, cash equivalents and restricted cash during the first six months of 2026 reflected net cash provided by financing activities of $43.4 million, which was primarily driven by $49.1 million of net proceeds received from the sale of common stock and $2.0 million of proceeds received from the exercise of pre-existing common stock warrants, partially offset by $7.8 million of treasury share repurchases related to the net settlement of employee equity awards. The Company used operating cash of $20.7 million during the six-month period to support operations and working capital, the majority of which consisted of strategic investments in antimony feedstock inventory. The Company also invested $22.8 million in capital expenditures during the first six months of 2026, primarily to advance the Thompson Falls expansion, acquire the milling facility located in Radersburg, Montana, and fund other strategic capital investments including additional critical mineral rights acquisitions. The Thompson Falls expansion was partially funded by the $12.8 million payment received in April 2026 for milestones achieved under the Defense Production Act grant award from the DoW.

The Company also holds an investment in Larvotto Resources Limited with a fair value of USD $43.2 million as of June 30, 2026.The Company recorded an unrealized gain of USD $6.8 million on the investment during the second quarter. Since quarter-end, the investment has continued to appreciate and had a market value of approximately USD $46.7 million based on the closing market price on August 10, 2026, an increase of approximately USD $3.5 million since June 30, 2026.

2026 Outlook

Updates Fiscal Year 2026 Revenue Guidance to a Range of $60 Million to $75 Million

The Company is updating its full-year 2026 gross revenue guidance to a range of $60 million to $75 million, revised from prior guidance of $125 million. The revised range reflects three principal factors: (1) a material decline in market prices for antimony since guidance was originally established in late 2025, when spot market pricing exceeded $28 per pound, versus spot market pricing (not the Company's realized pricing) of approximately $10.50 per pound during the second quarter; (2) a shift to the future in the timing of certain DLA antimony metal ingot deliveries related to the pace of the Thompson Falls capacity expansion and the customary timing of government contract coordination; and (3) the Company's updated view of second half production and shipment cadence. Importantly, underlying government and industry demand for domestically sourced antimony remains robust, and the Company continues to expect the current DLA IDIQ contract to be a meaningful long-term revenue contributor. As Thompson Falls capacity utilization increases, in combination with our additional new processing capacity in our Radersburg facility, the Company expects to expand the volume of antimony products it can supply to both government and commercial customers, further supporting revenue growth and product diversification into the back half of 2026 and into 2027.

Management Commentary

Commenting on the second quarter and six months ended June 30, 2026 results, Mr. Gary C. Evans, Chairman and Chief Executive Officer of US Antimony Corporation, stated: "While our overall operations are continuing to improve markedly each month, those successes are only slowly trickling into our financial performance. While we made our first deliveries to the government during the second quarter, none of that achievement was reflected during this financial reporting period. We currently anticipate the third quarter should see a minimum of $9.0-$10.0 million of additional sales, all to the US Government. With a total of $57.3 Million in antimony ingot orders from the DLA on our books today, we are working tirelessly to fulfill these purchases orders by year-end. Worldwide antimony prices declined during the first six months of 2026 which has obviously affected our revenue projections. However, we took advantage of that opportunity by significantly increasing our existing inventory (up 178% from year-end) while our new smelter was being commissioned. Management's current outlook reflects expectations for the balance of 2026 regarding increased shipments to both the DLA and our existing industrial customers, the Thompson Falls expansion becoming fully operational on all furnaces during the third quarter of 2026, continued ramp-up of in-house antimony ore processing in both Montana and Mexico, and sustained demand for critical minerals and our zeolite products."

The Company mines, purchases, and processes ore primarily into antimony oxide, antimony metal, antimony trisulfide, and precious metals at its facilities located in Montana and Mexico. Antimony oxide is used to form a flame-retardant system for plastics, rubber, fiberglass, textile goods, paints, coatings, and paper, as a color fastener in paint, and as a phosphorescent agent in fluorescent light bulbs. Antimony metal is used in bearings, storage batteries, and ordnance. Antimony trisulfide is used as a primer in ammunition. The Company also recovers precious metals, primarily gold and silver, at its Montana facility from third-party ore. At its Bear River Zeolite ("BRZ") facility located in Idaho, the Company mines and processes zeolite, a group of industrial minerals used in water filtration, sewage treatment, nuclear waste and other environmental cleanup, odor control, gas separation, animal nutrition, soil amendment and fertilizer, and other miscellaneous applications. From 2024 through 2026, the Company has acquired mining claims, real properties (patented claims), and leases located in Alaska, Montana, and Ontario, Canada - including the Radersburg flotation mill acquired in the first quarter of 2026 - to reduce the cost of third-party antimony ore purchases and to expand its product offerings.
