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.

DLA Delivery Schedule

Shipment Pounds Value

1 & 2 (Delivered) ~82,000 ~$2.60 Million

3 & 4 (In Transit) ~81,000 ~$2.60 Million

5, 6, 7 (Waiting on Inspection) ~126,000 ~$3.97 Million

~$9.17 Million

·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 o

Greetings. Welcome to the United States Antimony Corporation First Quarter 2026 Financial and Operating Results Conference call. At this time, all participants are in a listen-only mode. A question-and-answer session will follow the formal presentation. [Operator Instructions] Please note, this conference and webcast is being recorded.

I will now turn the call over to your host, Gary C. Evans, Chairman and CEO. You may begin.

Gary Evans - Chief Executive Officer &

Chairman, United States Antimony Corporation

Thank you, Paul, and welcome to our listeners. The news release on our earnings should be out any moment now. It was taking a little bit longer to get out, but it should be out within a minute or two.

First, I’d like to start by introducing other members of the company’s management team who has joined me today on this call. We have seven speakers from management who’ll be talking about their respective divisions because we have a lot to say, quite frankly. So, those parties are as follows: Rick Isaak, Senior Vice President and Chief Financial Officer; Shawn Winkler, our Interim Chief Financial Officer; Joe Bardswich, our Director and Executive Vice President and our Chief Mining Engineer; Melissa Pagen, President and Chief Operating Officer of our Bear River Zeolite division; Jeff Fink, Vice President of our Antimony division up in Thompson Falls; Aaron Tenesch, who’s Vice President of our Antimony division, predominantly involved in procurements as well as Radersburg; and then Jonathan Miller, who’s Vice President of our Investor Relations.

Before I turn over the conference call today to Rick and Shawn to discuss our financial report, I first want to say that I have never been more excited about where this company is going. If you are, as an investor, knew only half as much as I do today, you’d also feel the excitement. This is no longer just an antimony company. Read the heading of our press release today. It says antimony, cobalt, gold, tungsten, and zeolite. We’re making significant progress on all of these mineral developments, as you will hear today from our seasoned management team, as they go over what all we’re up to. Rick, you’re up, and let us hear about the first quarter earnings.

Richard Isaak - Senior Vice President &

Chief Financial Officer, United States Antimony Corporation

Thanks, Gary. As announced in a prior press release, I took a leave of absence a couple of weeks ago to take care of some personal matters. It was fortunate that we’ve been working with a very talented financial person, Shawn Winkler, who could step in as interim CFO. Shawn’s experience over the prior 20-plus years includes corporate finance, capital markets, and executive leadership. He recently served as CFO of a full-service engineering, procurement, and construction firm in the energy industry and was an investment banker for over 15 years. Shawn’s been working on financial projects for the company since late last year and knows the management and finance teams well. So, this was an easy transition.

Okay. Next, I’ll provide some comments on our consolidated results. Sales for the first quarter of 2026 were $6.8 million, nearly comparable to last year’s sales of $7 million. Antimony segment sales were down 2%, and Zeolite segment sales were down 7%. Gross profit for the first quarter of 2026 decreased $1.3 million compared to last year’s first quarter. The majority of this decrease was due to higher labor, factory, and important freight costs. These cost increases were needed, kind of like Gary was saying, to get the talent, factory, and inventory we need for the expected ramp-up in production for the remainder of this year. We expect these costs to improve with economies of scale as sales increase.

Net loss for the first quarter of 2026 was $11.3 million, which was primarily due to non-cash stock compensation expense of $4.8 million and an unrealized loss on our investment in our Larvotto equity securities o
