Rhea-AI Filing Summary

United States Antimony Corporation reported lower sales and a swing to loss while significantly strengthening its balance sheet and advancing growth projects for the six months ended June 30, 2026. Revenue was $14,709,670, down from $17,525,128 a year earlier, with antimony sales declining and zeolite sales increasing. Cost inflation and sharply higher operating expenses, including $7,738,892 of share-based compensation, drove an operating loss of $14,498,095 versus prior-year operating income of $377,999. The company recorded a net loss of $11,184,200 compared with net income of $728,079 in 2025.

Liquidity improved through equity issuance and a federal grant. Cash and cash equivalents were $41,434,379 and total assets $190,616,714, while debt remained low at $334,775. An at-the-market stock program raised $49,070,838 net, and a $27.0 million Defense Production Act grant is funding expansion of the Thompson Falls, Montana facility, of which $12,848,246 has been recognized as a reduction of property, plant and equipment. The smelter expansion, with total estimated capital of about $39 million, was substantially completed in the quarter. The company also holds a $43,219,151 equity stake in Larvotto Resources Limited, generating significant unrealized gains, and secured a five-year IDIQ contract with the U.S. Defense Logistics Agency with a maximum value of $245 million, with initial shipments of approximately 82,000 pounds of antimony to be recognized as $2.6 million of third-quarter revenue.

Positive

  • $27.0 million Defense Production Act grant supports expansion and modernization of domestic antimony processing and Alaskan mining operations, with $12.8 million already applied to reduce project capital costs.
  • A five-year IDIQ contract with the U.S. Defense Logistics Agency for antimony metal ingots has a maximum value of $245 million, with initial shipments of about 82,000 pounds generating $2.6 million of revenue in July 2026.
  • Cash and cash equivalents of $41,434,379 and low total debt of $334,775 reflect a strong liquidity position following an at-the-market equity raise of $49,070,838 net.
  • The Thompson Falls, Montana smelting capacity expansion, with estimated capital expenditures of about $39 million, was substantially completed and $4.1 million of assets were placed in service in the quarter.

Negative

  • Revenue declined to $14,709,670 for the first half of 2026 from $17,525,128 in 2025, driven by lower antimony sales.
  • The company reported a net loss of $11,184,200 for the first six months of 2026 versus net income of $728,079 a year earlier, reflecting sharply higher operating expenses.
  • Net cash used in operating activities increased to $20,720,183 for the first half of 2026 from $2,356,986, driven by losses, inventory build, and working capital outflows.
  • Share-based compensation rose to $7,738,892 for the first half of 2026 from $832,297 in 2025, materially increasing operating expenses and contributing to the period’s loss.

Filing Explained

The $27 million grant is not fully committed: $16.2 million was obligated, while $14.2 million remained milestone- or authorization-dependent at June 30, 2026.

United States Antimony Corporation’s Form 10-Q, an unaudited quarterly report, records the company’s financial position as of June 30, 2026 and discloses new financing, joint-venture, grant, and development commitments.

The company holds a 49% interest in a hydrometallurgical joint venture, has contributed $149,000, and expects to fund its share of future capital spending; the venture remained in early organizational development with no significant operations by June 30, 2026.

A $4.0 million convertible note receivable is classified as a current asset because the company can demand repayment, and it also has the right to convert the debt into membership interests in the borrower; the note is secured and includes a technology license.

The company was obligated to make approximately $7.0 million of future payments for mining claims and leases and had approximately $4.9 million of exploration and development spending commitments, although the agreements allow termination without cause that relieves future obligations.

Although the grant award totals $27.0 million, only $16.2 million was currently obligated at the reporting date, while $14.2 million had not been recognized because it remained subject to future milestones and approval.

The grant’s remaining funding is tied to milestone completion and formal acceptance through January 4, 2028, while the joint venture’s additional contributions depend on approved budgets and its development schedule.

Indefinite Delivery, Indefinite Quantity (IDIQ) contract regulatory
"a five-year, sole-source Indefinite Delivery, Indefinite Quantity (IDIQ) contract with the U.S. Defense"
An indefinite delivery, indefinite quantity (IDIQ) contract is a purchasing agreement where a buyer commits to buy goods or services as needed over a set time period, without specifying exact quantities up front, while setting a minimum and a maximum total value. For investors, IDIQs matter because they can create predictable revenue streams and backlog like a standing order from a large customer, but actual cash flow can vary depending on how much the buyer calls off under the contract.
Defense Production Act regulatory
"a $27.0 million grant by the U.S. Department of War under Title III of the Defense Production Act"
A U.S. law that lets the federal government prioritize, allocate, and financially support the production and supply of goods and services needed for national defense or major emergencies. For investors, it can quickly change a company’s sales outlook and production plans by directing contracts, speeding approvals, or providing subsidies—like a city mayor telling factories which products to make during a crisis—so affected companies may see rapid revenue or cost shifts.
net smelter return royalty financial
"a 1.5% net smelter return royalty based on the value realized from ore mined"
A net smelter return (NSR) royalty is a contractual right to receive a percentage of the revenue from minerals sold after they are processed and refined, with common deductions for transportation and refining fees. Investors care because an NSR provides a predictable slice of mining project income without owning the mine, so it affects expected cash flow, risk exposure to commodity prices, and the valuation of both the royalty and the operating project—similar to collecting a portion of rent after paying building maintenance costs.
at the market offerings financial
"sold 4,326,433 shares of its common stock in “at the market offerings” and received gross proceeds"
At-the-market offerings are a way for a company to raise cash by selling newly issued shares directly into the open market at the current trading price through a broker, rather than in a single large sale. Think of it like topping up a gas tank a little at a time at whatever the pump price is; it gives the company flexibility to raise money when conditions are favorable but can increase the number of shares outstanding and dilute existing investors, and frequent or large sales can put downward pressure on the stock price.
equity method of accounting financial
"the Company accounts for its investment in the JV under the equity method of accounting"
An equity method of accounting is the way a company reports its financial interest in another business when it has significant influence but not full control, typically owning between about 20% and 50% of the voting stock. Instead of listing the investment at purchase cost or consolidating every line item, the investor records its proportional share of the other company’s profits or losses and adjusts the investment value for dividends or impairments, so investors see the economic impact of that stake. This matters because it changes reported earnings and asset values in a way that reflects ongoing performance—similar to showing your share of a small business’s monthly profit on your own books rather than just the amount you originally paid for your share—and helps gauge how much influence that stake has on the investor’s financial health.
asset retirement obligations financial
"Asset retirement obligations | ​ | | 2,785,687 | ​ | | 2,720,658"
Asset retirement obligations are a company’s recorded promise to pay for dismantling, cleaning up, or restoring property when a long-lived asset is retired — for example decommissioning a plant or removing equipment. Companies estimate the future cleanup cost today and book it as a liability (and add the cost to the asset), so it affects the balance sheet, reported profits over time, and future cash needs; investors watch it like a planned bill that can reduce cash available for returns.
Revenue $14,709,670 decreased from $17,525,128 for the six months ended June 30, 2025
Net income (loss) $(11,184,200) compared with net income of $728,079 for the six months ended June 30, 2025
Operating income (loss) $(14,498,095) compared with operating income of $377,999 for the prior-year period

UNITED STATES ANTIMONY CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

June 30, 2026

NOTE 1 - NATURE OF OPERATIONS

United States Antimony Corporation and its subsidiaries in the U.S., Mexico, and Canada (“USAC,” the “Company,” “Our,” “Us,” or “We”) sell antimony, zeolite, and precious metals primarily in the U.S. and Canada. The Company mines, purchases and processes ore primarily into antimony oxide, antimony metal ingots, antimony trisulfide, and precious metals, primarily gold and silver, 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 ingots are 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. In April 1998, the Company formed US Antimony de Mexico, S.A. de C.V. (“USAMSA”) to produce antimony products in Mexico, and, in August 2005, the Company formed Antimonio de Mexico, S.A. de C.V. (“ADM”) to explore and develop antimony and precious metal deposits in Mexico. The Company formed Bear River Zeolite Company (“BRZ”) in 2000 where at its 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. Beginning in 2024 and continuing in 2025 and 2026, the Company has acquired mining claims, real properties (patented claims) and leases located in Alaska, Montana and Ontario, Canada all of which are prospective for both antimony ore and other critical minerals. These acquisitions have the potential to increase antimony ore throughput at the Company’s facilities, reduce the cost of third-party antimony ore purchases, provide reliability of supply, expand the Company’s product offerings and diversify its critical mineral portfolio. The Company has also entered into an agreement to acquire certain exploration rights for mining properties located in the southeastern United States.

NOTE 2 - BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of its financial position as of June 30, 2026, and its results of operations and cash flows for the three and six months ended June 30, 2026 and 2025. The Condensed Consolidated Balance Sheet as of December 31, 2025, was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements.

These unaudited interim financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). These unaudited interim financial statements should be read in conjunction with the annual audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the Securities and Exchange Commission on March 19, 2026.

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities known to exist as of the date the financial statements are published, and the reported amounts of revenues and expenses during the reporting period. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of the Company’s consolidated financial statements; accordingly, it is possible that the actual results could differ from these estimates and assumptions, which could have a material effect on the reported amounts of the Company’s consolidated financial position and results of operations. Operating results for the three and six months ended June 30, 2026, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2026.

Reclassifications

Certain reclassifications have been made to conform prior period amounts to the current period’s presentation. These reclassifications have no effect on the results of operations, stockholders’ equity or cash flows as previously reported.

UNITED STATES ANTIMONY CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

June 30, 2026

Investment in Joint Venture

In February 2026, the Company entered into a joint venture (“JV”) agreement with Americas Gold and Silver Corporation (“Americas”) to construct and operate a hydrometallurgical processing facility. The JV is owned 51% by Americas and 49% by the Company. Because governance is shared through a management committee with equal representation and all significant decisions require unanimous approval, the Company does not have a controlling financial interest, however it does have the ability to exercise significant influence. As a result, the Company accounts for its investment in the JV under the equity method of accounting.

Under the equity method, the initial investment is recorded at cost and subsequently adjusted for the Company’s proportionate share of the JV’s net income or loss, additional capital contributions, and distributions received. The Company’s share of the JV’s results is recognized in “Equity in losses of joint venture” in the Condensed Consolidated Statements of Operations, and the investment is presented within noncurrent assets on the Condensed Consolidated Balance Sheets. The Company periodically reassesses whether it has a controlling financial interest in the JV and evaluates the investment for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable.

Recent Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (the “FASB”) issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires disclosure about the types of costs and expenses included in certain expense captions presented on the income statement. The new disclosure requirements are effective for the Company’s annual periods for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted, and may be applied either prospectively or retrospectively. The Company is currently evaluating the potential impact this update will have on its consolidated financial statements and expense disclosures in the notes to the consolidated financial statements.

In September 2025, the FASB issued ASU No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The amendments in this ASU clarify and refine the criteria for capitalizing costs related to internal-use software. Under the new guidance, capitalization is permitted when both of the following conditions are met: (i) management has authorized and committed to funding the software project, and (ii) it is probable that the project will be completed, and the software will be used to perform the function intended. This ASU will be effective for annual periods beginning after December 15, 2027, for interim reporting periods beginning within those annual periods, and early adoption is permitted. Management is currently evaluating this update to determine its impact on the Company’s consolidated financial statements.

In December 2025, the FASB issued ASU No. 2025-10, Government Grants (Topic 832): Accounting for Government Grants by Business Entities. This ASU provides guidance on the recognition, measurement, presentation, and disclosure of government grants received by business entities. Under the new guidance, government grants are recognized when there is reasonable assurance that the Company will comply with the conditions of the grant and that the grant will be received. Grants related to income are presented either as other income or as a reduction of the related expense, while grants related to assets are recorded either as deferred income or as a reduction of the carrying amount of the related asset. The guidance in this ASU is effective for fiscal years beginning after December 15, 2028, and interim reporting periods within those annual reporting periods. Early adoption is permitted in both interim and annual reporting periods in which financial statements have not yet been issued or made available for issuance. If a business entity adopts the amendments in this ASU in an interim reporting period, it must adopt them as of the beginning of the annual reporting period that includes that interim reporting period. The Company early adopted this guidance effective January 1, 2026. See NOTE 9 – GOVERNMENT GRANT for further details.

The Company does not believe that issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on its condensed consolidated financial statements.

NOTE 3 – EARNINGS PER SHARE

Basic earnings per share (“EPS”) is computed as net income (loss) available to common stockholders divided by the weighted average number of common shares outstanding for the period. Diluted EPS is calculated the same as Basic EPS but reflects the potential dilution that could occur from common shares issuable through stock options, restricted stock units (“RSUs”), and warrants in the weighted average number of common shares outstanding. Each stock option, RSU, and warrant represents the right to receive one share of the Company’s common stock.

The following table sets forth the calculation of basic and diluted weighted average shares outstanding and net income (loss) per share for the periods presented:

NOTE 4 – FAIR VALUE MEASUREMENTS

The Company uses the fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, essentially an exit price, based on the highest and best use of the asset or liability. The levels of the fair value hierarchy are:

Level 1—Quoted market prices in active markets for identical assets or liabilities;
Level 2—Significant other observable inputs (i.e., quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable, such as interest rate and yield curves, and market-corroborated inputs); and
Level 3—Unobservable inputs in which there is little or no market data, which require the reporting unit to develop its own assumptions.

Table of Contents

UNITED STATES ANTIMONY CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

June 30, 2026

The classification of fair value measurements within the established three-level hierarchy is based upon the lowest level of input that is significant to the measurements. Financial instruments, although not recorded at fair value on a recurring basis, include cash and cash equivalents, held-to-maturity debt securities, restricted cash for reclamation bonds, note receivable and debt obligations. Equity investments with readily determinable fair values are measured at fair value on a recurring basis, with changes in fair value recognized in earnings.

The carrying amount of cash and cash equivalents approximates fair value because of its short-term nature. The estimated fair values of investments in debt securities held to maturity were based on Level 2 inputs. The carrying amount of restricted cash for reclamation bonds and the note receivable approximate fair value based on their contractual terms. The fair value of the Company’s debt is estimated to be face value based on the contractual terms of the underlying debt arrangements and market-based expectations. The Company’s investment in equity securities is classified as a Level 1 fair value measurement because it is valued each reporting period using readily available quoted market prices from the Australian Securities Exchange.

The Company’s trade accounts receivable balance related to contracts with customers was $2,607,687 at June 30, 2026 and $4,213,305 at December 31, 2025, which is net of an allowance for credit losses of $1,345 and $909 at June 30, 2026 and December 31, 2025, respectively. The Company’s products do not involve any warranty agreements and product returns are not typical.

In September 2025, the Company secured a five-year, sole-source Indefinite Delivery, Indefinite Quantity (IDIQ) contract with the U.S. Defense Logistics Agency (DLA) Strategic Materials, which is responsible for managing the National Defense Stockpile (NDS). The contract, with a maximum value of $245 million, is for the sale of antimony metal ingots (99.65% purity) to replenish the NDS through September 2030. Pricing is determined at the time each delivery order is placed based on prevailing market rates along with certain specific fees and each shipment will represent a separate performance obligation satisfied at a point in time. As a result, revenue will be recognized when each shipment of antimony metal ingots is delivered to the DLA’s depot and formally accepted by the government. Subsequent to entering into this agreement, the Company received sales orders pursuant to this contract totaling approximately $12 million. During June 2026, the Company fulfilled its first two shipments under the contract with the DLA. These shipments, which consisted of approximately 82,000 pounds of antimony metal ingots, were formally accepted by the DLA in July 2026. Under the terms of the contract, control transfers to the DLA when formal acceptance has occurred. As a result, the Company recognized the $2.6 million of revenue related to these shipments in July 2026, which will be included in the Company’s third-quarter financial results.

In November 2025, the Company executed a five-year sales agreement with a new industrial customer for the sale of antimony trioxide. Once the monthly delivery schedule through December 2026 specified in the agreement is completed, subsequent deliveries, pricing (pursuant to semiannual market-based adjustments), and volume commitments will be subject to mutual written agreement between the Company and the customer every six months. During the three and six months ended June 30, 2026, the Company recognized $1.0 million and $3.7 million, respectively, of revenue related to this contract.

Margin Credit Line

In 2025, the Company secured a $19.0 million margin credit line with a national bank, which bears interest at one percent above the base commercial rate. The Company’s U.S. Treasury Strips serve as collateral for the margin credit line. During the first and second quarters of 2026, the Company borrowed $5.0 million and $10.0 million, respectively, under the margin credit line, with each borrowing repaid prior to the end of the respective quarter. The Company had no outstanding borrowings under the margin credit line outstanding as of June 30, 2026 or December 31, 2025. Availability under the margin credit line is subject to customary margin requirements based upon a percentage of the value of the pledged securities.

NOTE 7 – INVENTORIES

Inventories at June 30, 2026 and December 31, 2025 consisted primarily of finished antimony metal ingots and antimony oxide products, antimony ore and concentrates, and finished zeolite products. Inventories are stated at the lower of first-in, first-out cost or estimated net realizable value.

At June 30, 2026 and December 31, 2025, inventories were valued at cost, except for the portion of inventory that is valued at net realizable value because costs are greater than the amount the Company expects to receive on the sale of this inventory. During the six months ended June 30, 2026, the Company recorded a write-down of $161,456 to adjust antimony inventory to its NRV. There were no inventory NRV adjustments during the six months ended June 30, 2025.

NOTE 8 – NOTE RECEIVABLE

In 2025, as part of an international strategic supply agreement with a supplier for the purchase of processed antimony meeting specified quality standards over an approximate 36-month period, the Company extended a secured promissory note to the supplier in the original principal amount of $2,500,000. On February 1, 2026, the note was amended and restated to incorporate accrued interest into the outstanding principal balance. On April 1, 2026, the note was again amended and restated with an outstanding principal balance of $2,486,524, which included accrued interest. The amended note required monthly principal payments of $100,000 beginning July 1, 2026, with the remaining balance due on December 31, 2026. The amended note also included a demand feature permitting the Company to require immediate repayment.

During the second quarter of 2026, the parties entered into a new Convertible Promissory Note (the “Convertible Note”), which replaced the previously outstanding note receivable. The Company entered into the Convertible Note as part of its ongoing strategic commercial relationship with the supplier. The additional funding is intended to support the supplier’s continued development of its antimony processing capabilities and future product supply.

The Convertible Note has a principal balance of $4,000,000 and bears interest at 10.0% per annum. The principal balance of the Convertible Note includes the outstanding indebtedness under the most recent financing arrangement, $40,752 of accrued interest, $356,570 previously advanced for inventory that had not been received as of the date of the Convertible Note, and $1,116,154 of additional funding provided by the Company. The Convertible Note matures upon the earliest of (i) five days following written demand by the Company, (ii) the occurrence of an event of default, or (iii) May 29, 2028. The Convertible Note also grants the Company the right, at its election, to convert all or a portion of the outstanding indebtedness, including accrued and unpaid interest, into membership interests of the borrower which owns a hydrometallurgical processing facility located internationally. As a condition of the Convertible

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

June 30, 2026

Note, the Company received an exclusive license to this antimony processing technology for use in North America and Australia. In addition, the processed antimony being received from this supplier is below prevailing international market rates.

The Convertible Note is secured by substantially all of the assets of the borrower and is further supported by a personal guaranty from the borrower’s principal owner. The Convertible Note also contains mandatory prepayment provisions, setoff rights, and other customary creditor protections. Management evaluated the embedded conversion feature and concluded that separate derivative accounting was not required. The Company evaluated the collectability of the Convertible Note in accordance with its expected credit loss methodology and concluded that no allowance for expected credit losses was required after considering, among other factors, the pledged collateral, contractual demand rights, the borrower’s current operating status, expected future operating cash flows, and other credit enhancements associated with the financing arrangement. Because the Company has an unconditional contractual right to demand repayment at any time, the Convertible Note is classified as a current asset in the Condensed Consolidated Balance Sheet.

NOTE 9 – GOVERNMENT GRANT

In March 2026, the Company was awarded a $27.0 million grant by the U.S. Department of War under Title III of the Defense Production Act (“DPA”) to support the expansion and modernization of its domestic antimony processing operations and to fund a portion of the Company’s Alaskan antimony mining operations. The award is administered through the Defense Industrial Base Consortium (“DIBC”), which is managed by Advanced Technology International.

The award is structured as a milestone-based, firm fixed-price arrangement, with $16.2 million representing currently obligated funding associated with initial project milestones and the remaining $10.8 million related to future phases subject to additional authorization by the U.S. government. Payments under the agreement are contingent upon the achievement and formal acceptance of specified milestones, as well as compliance with certain ongoing requirements, including environmental, reporting, and project execution obligations.

As part of those execution obligations, the Company is required to contribute approximately $3.9 million of the total project cost and is responsible for executing the expansion of its Thompson Falls, Montana facility, as well as advancing related mining integration activities in Alaska. The period of performance under the agreement extends through January 4, 2028.

The Company has elected to early adopt ASU 2025-10, Government Grants (Topic 832), effective January 1, 2026, and account for the grant as a non-exchange transaction within the scope of ASC 832. Pursuant to this guidance, management evaluates the recognition of grant funding based on whether it is probable that the Company will comply with the substantive conditions of the agreement and that the grant will be received.

On March 25, 2026, the Company received formal approval from the DIBC confirming the achievement of three project milestones associated with $12.8 million of committed funding. Management concluded that the recognition criteria under ASC 832 had been satisfied because the related performance conditions had been met and receipt of the funding was probable. As a result, during the first quarter of 2026, the Company recognized a $12.8 million government grant receivable, which was collected in April 2026. Consistent with its election to apply the cost accumulation approach under ASU 2025-10 for grants related to long-lived assets, the Company recognized the corresponding grant proceeds as a reduction of the carrying amount of Property, Plant, and Equipment (“PP&E”) associated with the Thompson Falls facility expansion. Grant proceeds are allocated to the underlying depreciable asset categories on a pro rata basis relative to the capitalized costs incurred. The related cash inflow was classified as an investing activity in the Condensed Consolidated Statement of Cash Flows, consistent with the classification of the capital expenditures the grant was intended to offset.

The Thompson Falls facility expansion was substantially completed and $4.1 million of the related assets were placed in service late in the second quarter of 2026. The reduced carrying value of the depreciable assets is expected to result in lower depreciation expense prospectively over the remaining estimated useful lives of those assets.

As of June 30, 2026, the Company had not recognized any amounts related to $14.2 million of funding that remained subject to future milestone achievement and approval. This amount includes the $10.8 million portion of the award that has not yet been authorized by the U.S. government. The Company expects to receive additional funding under the agreement as further milestones are completed, and the related funding is subsequently approved.

In January 2026, the Company purchased substantially all assets associated with a precious metals milling facility located in Radersburg, Montana for total consideration of approximately $4,816,000, which included approximately $66,000 of direct transaction costs. The acquired assets included land, buildings and site improvements, and machinery and equipment. The transaction was accounted for as an asset acquisition, and the purchase price was allocated to the acquired assets based on their relative fair values. Following this allocation, machinery and equipment totaled approximately $1,722,000, buildings and improvements totaled approximately $2,615,000, and land totaled approximately $479,000. The acquired assets are included in property, plant and equipment and the “All Other” category for segment reporting. The acquired assets will be depreciated over their estimated remaining useful lives, which range from 1 to 10 years for machinery and equipment and 20 to 30 years for buildings and improvements.

Mineral rights and interests

In January 2026, the Company paid $1.3 million to purchase 36 federal mining claims located in the Koyukuk Mining District of Alaska (commonly referred to as Nolan Creek) that are prospective for both antimony and gold. This agreement does not require the Company to make any royalty payments.

In January 2026, the Company paid approximately $108,000 to repurchase 1% of the net smelter return royalty associated with 50 single-cell mining claims located in the Sudbury District of Ontario, Canada (commonly referred to as Fostung Tungsten). The royalty obligation originated from the Company’s June 2025 acquisition of this property which was originally subject to a 1.5% net smelter return royalty based on the value realized from ore mined from the property.

In March 2026, the Company completed a series of mineral rights purchases in Sanders County, Montana (commonly referred to as Stibnite Hill), including three patented lode mining claims and the surface rights associated with a fourth patented lode mining claim, for aggregate consideration of approximately $815,000. The acquisitions were completed through separate purchase agreements and provide the Company with fee simple title to the underlying mineral properties.

This agreement requires net smelter royalty payments by the Company based on the value realized from minerals produced from the mining claims. The agreement can be terminated without cause at any time by the Company with thirty days’ written notice.

The Company has entered into multiple agreements to acquire mining claims, leases, and exploration rights in Alaska, Canada, and the southeastern United States. Pursuant to the terms of these agreements, the Company is obligated as of June 30, 2026 to make aggregate payments to purchase these claims of approximately $7.0 million, payable as follows: approximately $150,000 in the remainder of 2026, $600,000 in 2027, $650,000 in 2028, $3.3 million in 2029, and $2.35 million in 2030. In addition to these fixed payment obligations, the agreements generally require the Company to pay net smelter royalties based on the value realized from future production, with certain agreements providing the Company with the option to repurchase a portion of such royalties. The agreements also include aggregate exploration and development spending commitments of approximately $4.9 million over periods ranging from approximately three to five years. Each of the agreements may be terminated by the Company without cause upon notice, which would relieve the Company of future payment and spending obligations.

All payments related to these mining claims and leases that became due on or before June 30, 2026 were made by the Company pursuant to the terms of the underlying agreements. The payments made to acquire these mining claims and leases are capitalized in the “Mineral rights and interests” component of PP&E in the Condensed Consolidated Balance Sheets and included in the “All Other” category for segment reporting.

NOTE 11 – LEASES

Philipsburg Operating Lease

In September 2024, the Company executed a contract to lease a metals concentration facility located in Philipsburg, Montana. The Company amended the lease in March 2025 extending the term of the agreement to September 2, 2026. As a result of the amendment in March 2025, the Company reduced the ROU asset and corresponding lease liability by $37,448. During the three and six months ended June 30, 2025, the Company recorded $127,548 and $304,510, respectively, of lease expense related to this lease in the Condensed Consolidated Statements of Operations. During the first six months of 2026, there was no expense recorded for this lease since the agreement was terminated in September 2025. In the first quarter of 2026, the Company acquired a precious metals milling facility located in Radersburg, Montana, which replaced the Company’s need for the Philipsburg facility.

Dallas Operating Lease

In the first quarter of 2025, the Company executed a contract to lease office space for its corporate headquarters located in Dallas, Texas with a lease term of 24 months and total fixed payments during the term of $3,945 per month, or $94,680 in total. The Company is amortizing the lease on a straight-line basis over the term of the lease. The Company recorded the present value of the lease payments over the term as a lease liability and ROU asset. The Company used its incremental borrowing rate as the discount rate since the rate implicit in the lease was not readily determinable. The lease does not include any transfer of ownership of the office space at the end of the lease, nor any option to extend the lease or purchase the facility, nor any residual value guarantees. The Company cannot terminate the lease without cause and must provide the office space to the lessor at the end of the lease in the same condition as it was received.

Canada Operating Lease

On October 1, 2025, the Company leased office space located in Sudbury, Ontario, Canada with a lease term of 60 months that expires on September 30, 2030. The Company is required to make monthly base rent payments of $1,050 in Canadian dollars which are converted to U.S. dollars using the spot exchange rate in effect on the payment date. The Company recorded $22,772 in U.S. dollars as the present value of the rent payments as a lease liability and corresponding ROU asset and is amortizing the lease on a straight-line basis over the term of the lease. Since the monthly rent payments are made in Canadian dollars, the lease liability was initially measured using the spot exchange rate in effect on the lease commencement date and is remeasured into U.S. dollars at each reporting date with any resulting foreign currency transaction gains or losses recognized in earnings. The Company’s incremental borrowing rate was used as the discount rate since the rate implicit in the lease was not readily determinable. The lease does not include any transfer of ownership of the office space at the end of the lease, nor any option to purchase the facility, nor any residual value guarantees. The Company has the option to renew or extend the lease for one additional term of five years, provided written notice is given to the landlord at least six months prior to the lease expiring. The Company did not consider the additional lease term covered by the renewal option in the initial lease liability since exercise of the renewal option was not reasonably certain at lease commencement.

NOTE 12 – INVESTMENT IN EQUITY SECURITIES

In October 2025, the Company acquired 51.7 million, or approximately ten percent at that time, of the issued and outstanding shares of Larvotto Resources Limited (“Larvotto”) through twelve open-market cash purchases totaling $37,172,842 (measured in U.S. dollars). Larvotto is an Australian-based public company engaged in the exploration and development of critical minerals, particularly antimony and gold, whose shares are traded on the Australian Securities Exchange. Since the Company has less than a 20% ownership interest in Larvotto and does not exert significant influence through board representation, contractual governance rights, or other mechanisms that would allow participation in the financial or operational policy decisions of the business, the Company recorded this transaction as an investment in equity securities. The investment is measured at fair value each reporting period using readily available quoted market prices from the Australian Securities Exchange. As a result, the Company has classified the Larvotto investment as a Level 1 fair value measurement within the fair value hierarchy and all changes in its fair value are recorded as other income (expense), net, in the condensed consolidated statements of operations. These changes in fair value may result from movements in Larvotto’s share price, changes in the

Australian dollar (“AUD”) / U.S. dollar (“USD”) exchange rate, or a combination of both. The Company’s Larvotto investment is classified as a non-current asset in the condensed consolidated balance sheets because it is considered a strategic investment that may be held long-term. As of June 30, 2026 and December 31, 2025, the fair value of the investment reflected in the condensed consolidated balance sheet was $43,219,151 and $40,494,328, respectively, and unrealized gains of $6,786,253 and $2,724,823 were recorded as other income (expense) in the condensed consolidated statement of operations for the three and six months ended June 30, 2026, respectively. There were no unrealized gains or losses recorded as other income (expense) during the three and six months ended June 30, 2025.

NOTE 13 – INVESTMENT IN JOINT VENTURE

In February 2026, the Company entered into a joint venture agreement with Americas Gold and Silver Corporation (“Americas”) to construct and operate a new, state-of-the-art hydrometallurgical processing facility (the “JV”). The Company holds a 49% membership interest, with the remaining 51% held by Americas. While the Company is responsible for day-to-day activities of the JV, governance is shared through a management committee with equal representation from each member, and all significant decisions require unanimous approval. Accordingly, the Company does not have a controlling financial interest in the JV and accounts for its investment under the equity method of accounting.

The JV is expected to be funded in part through contributions of nonmonetary assets, including (i) rights to use proprietary hydrometallurgical processing technology to be contributed by the Company through a sublicense arrangement and (ii) rights to use and ultimately acquire the project site to be contributed by Americas through a staged lease-to-transfer structure. As of June 30, 2026, these nonmonetary contributions have not yet been made.

The Company has made capital contributions to the JV of $149,000 and is required to fund its proportionate share of future capital expenditures in accordance with the JV agreement. The Company expects to continue to make additional contributions as the JV progresses through the construction and development phase of the project. The timing and amount of such contributions will depend on the JV’s approved budgets and project development schedule which are in process.

The JV is currently in the early stages of organizational development and has not commenced any significant operational activities. For the three and six months ended June 30, 2026, the Company recognized equity in losses of the JV of $56,514 and $72,640, respectively, which primarily reflects organizational, development, and other pre-operating costs incurred by the JV. As of June 30, 2026, the carrying value of the Company’s investment in the JV was $76,360.

Earlier this year, the Company made a formal application on behalf of the JV to the Department of War for grant awards to fund the construction of this new hydrometallurgical processing facility. The likelihood of such future awards cannot yet be determined.

The financing arrangement provided for a fixed rate of 3.49% per annum. The financing arrangement is secured by a purchase money security interest in the wheel loader and is guaranteed by the Company. As of June 30, 2026, the outstanding principal balance under the agreement was $127,550, all of which was classified as current portion of long-term debt.

In April 2026, the Company acquired a mid-size front-end wheel loader to be used at its precious metals milling facility located in Radersburg, Montana pursuant to a financing arrangement with a total contractual obligation of approximately $238,000, payable in 48 monthly installments of $4,958 maturing in May 2030. The financing arrangement does not bear a stated rate of interest; accordingly, the Company recorded the equipment and related financing obligation at the present value of the future contractual payments using an imputed market interest rate of 6.0%. As a result, the Company recorded the equipment and debt at approximately $211,000 which is net of a debt discount of approximately $27,000, which is being amortized to interest expense over the term of the financing arrangement using the effective interest method. The financing obligation is secured by a purchase money security interest in the equipment. As of June 30, 2026, the outstanding principal balance consisted of $48,363 classified as current portion of long-term debt and $158,862 classified as long-term.

At June 30, 2026, principal payments on debt were due as follows:

NOTE 15 – TAX

Management estimates the Company’s 2026 effective tax rate to be 0% based on the Company’s year-to-date pretax loss, cumulative loss position, historical operating losses, and other available evidence supporting the continued need for a full valuation allowance against its net deferred tax assets. Although the Company reported net income for the second quarter of 2026, such income was the direct result of an unrealized gain on an equity investment that is reflected as a temporary difference for tax purposes. Accordingly, no income tax expense or benefit has been recorded for the three- and six-month periods ended June 30, 2026.

Mexico Tax Assessment

In 2015, the Mexican tax authority (“SAT”) initiated an audit of USAMSA’s 2013 income tax return. In October 2016, as a result of its audit, SAT assessed the Company $13.8 million pesos, which was approximately $666,400 in U.S. Dollars (“USD”) as of December 31, 2016. SAT’s assessment was based on the disallowance of specific costs that the Company deducted on the 2013 USAMSA income tax return. The assessment was settled in 2018 with no assessment due from the Company.

In 2019, the Company was notified that SAT re-opened its assessment of USAMSA’s 2013 income tax return and, in November 2019, SAT assessed the Company $16.3 million pesos, which was approximately $865,000 USD as of December 31, 2019. Management reviewed the 2019 assessment notice from SAT and, similar to the earlier assessment, believed the findings have no merit. An appeal was filed by the Company in November 2019 suspending SAT from taking immediate action regarding the assessment. In August 2020, the Company filed a lawsuit against SAT for resolution of the process and, in December 2020, filed closing arguments. In 2022, the Mexican court ruled against the Company in the above matter, which was subsequently appealed by the Company. In March 2024, Mexico’s appellate court ruled in favor of the Company with no assessment due related to this audit of USAMSA’s 2013 income tax return by SAT and instructed the lower court to issue a new ruling. In May 2024, Mexico’s lower court issued a final ruling on this matter in favor of the Company but left open the possibility for the SAT to re-open their audit. Subsequent to this judgment, the Company requested a final ruling on whether SAT can re-open this matter.

In January 2026, the Federal Administrative Justice Court (Tribunal Federal de Justicia Administrativa, “TFJA”) issued a final judgment in favor of the Company with respect to the SAT’s reassessment of USAMSA’s 2013 income tax return. The TFJA declared both the

underlying tax credit and the related administrative appeal resolution invalid, including prior assessments and associated interest, penalties, and additional employee profit sharing. The ruling addressed the substantive merits of the case and determined that the Company was not subject to the obligations asserted by SAT. As a result of this final judgment, the matter is considered resolved with no amounts due from the Company. This resolution had no impact on the Company’s consolidated financial statements, as no liability had been recorded in connection with this matter.

Mexico Import Value Added Tax

USAMSA recorded a receivable of $2,955,899 and $1,875,771 at June 30, 2026 and December 31, 2025, respectively, for the Import Value Added Tax (“IVA tax” or “VAT”) it pays on certain goods and services representing amounts to be reimbursed from the Mexican government. USAMSA recorded full reserves against its IVA tax receivable balances at June 30, 2026 and December 31, 2025, respectively, resulting in net IVA tax receivables of zero at both period ends.

NOTE 16 – COMMITMENTS AND CONTINGENCIES

Mine Safety Matters

Historically, BRZ has been assessed fines and penalties by the Mine Safety and Health Administration (“MSHA”). During the six months ended June 30, 2026, BRZ received four citations from MSHA, none of which were significant and substantial. All four citations were rectified by BRZ and terminated by MSHA either on the day the citations were issued or the day after. At June 30, 2026 and December 31, 2025, BRZ had no accrued liabilities relating to MSHA citations.

BRZ’s Zeolite Lease

BRZ has a lease through December 31, 2034 with Zeolite, LLC that entitles BRZ to surface mine and process zeolite on property in Preston, Idaho, in exchange for an annual payment and a royalty payment, which is based on the amount of zeolite shipped from the leased property (“BRZ Lease”).

Thompson Falls, Montana Facility Expansion

In April 2025, the Company engaged engineering and construction firms to expand its existing smelting operating capacity located in Thompson Falls, Montana. Total capital expenditures associated with the expansion plans are estimated to be approximately $39 million, of which approximately $37 million has been formally agreed to with various third-party vendors. As of June 30, 2026, the Company has incurred approximately $33 million related to these commitments. The Thompson Falls facility expansion was substantially completed during the second quarter of 2026, resulting in approximately $4 million of project costs being transferred from construction in progress to the appropriate PP&E asset categories as the related assets were placed in service late in the quarter. The remaining approximately $29 million of gross project costs are included in the “Construction in progress” component of PP&E in the Condensed Consolidated Balance Sheets presented net of the $12.8 million of grant funding received under the Company’s DIBC award, as discussed in NOTE 9 – GOVERNMENT GRANT.

Inventory Purchase Commitments

As of June 30, 2026, the Company had outstanding purchase commitments for antimony inventory with an aggregate estimated cost of approximately $5 million, which is not reflected in the Condensed Consolidated Balance Sheet. The Company expects to take delivery of this inventory during the remainder of 2026.

Legal Matters

The Company’s Mexican subsidiary USAMSA is a defendant in a commercial lawsuit relating to historical obligations under an agreement for certain services related to mining claims in Mexico. The action is in its initial stages with the plaintiff seeking approximately $339,000 in damages and $54,390 of associated value added tax. In connection with the litigation, a Mexican court issued a precautionary attachment order requiring the Company to restrict approximately $339,000 held in a bank account as security pending

June 30, 2026

resolution of the matter and until posting of a judicial surety bond to substitute for the attachment is completed. As a result, the Company has classified such amount as restricted cash in the accompanying Condensed Consolidated Balance Sheet as of June 30, 2026. The Company intends to vigorously defend the action and, based on the information currently available and after consultation with legal counsel, management does not believe a loss is probable. Accordingly, no liability has been recorded as of June 30, 2026, although an adverse outcome remains reasonably possible. The Company has subsequently filed a countersuit against the same party in excess of the amounts described to recover amounts previously paid to the party for services subject to the disagreement.

The Company is from time to time involved in various other claims, legal proceedings and complaints arising in the ordinary course of business. The Company does not believe that adverse decisions in any such pending or threatened proceedings, or any amount that the Company might be required to pay by reason thereof, would have a material adverse effect on the financial condition or future results of the Company.

Share-based compensation

In December 2023, shareholders approved the Company’s 2023 Equity Incentive Plan (“the Plan”), which provided for the grant of incentive stock options and non-qualified stock options and other types of awards. The general purpose of the Plan is to provide a means whereby eligible employees, officers, directors and other service providers develop a sense of proprietorship and personal involvement in the development and financial success of the Company, and to encourage them to devote their best efforts to our business, thereby advancing our interests and the interests of our shareholders. On July 31, 2025, the Company’s shareholders approved the Amended and Restated 2023 Equity Incentive Plan (the “Amended Plan”) which increased the maximum number of shares of common stock available for issuance under the Amended Plan to 23,700,000 shares.

Expected term – The expected term represents the period of time that options are expected to be outstanding. As the Company does not have sufficient historical exercise behavior, it uses the contractual term of the option or the simplified method as defined in Staff Accounting Bulletin Topic 14 for the expected term assumption.

Risk-free interest rate – The risk-free interest rate is based on the U.S. Treasury rate in effect at the time of the grant with an equivalent term approximating the expected term of the options.

Expected dividend yield—The Company bases the expected dividend yield assumption on the fact that it has never paid cash dividends and has no present intention to pay cash dividends.

Expected volatility – The expected volatility is based on the historical volatility of our stock price over the expected term of the stock option.

Treasury Stock

The Company retains and holds shares of its common stock as treasury stock to manage the settlement of employee equity awards. Shares are retained primarily to cover the option exercise price and, if any, required tax withholding for cashless stock option exercises and to satisfy employees’ tax obligations upon RSU vesting. During the six months ended June 30, 2026, the Company withheld 372,185 shares of common stock, with an aggregate value of $3,654,449, in connection with certain stock option exercises. These shares were retained as treasury stock to satisfy the related exercise price and, where applicable, payroll tax withholding obligations. Also, during the six months ended June 30, 2026, 528,362 newly issued common shares with a cost of $5,189,407 were retained by the Company as treasury stock to satisfy the mandatory payroll tax obligations resulting from the vesting of RSUs. There were no common shares retained and transferred to treasury stock during the six months ended June 30, 2025.

NOTE 18 – BUSINESS SEGMENTS

The Company has two reportable segments: antimony and zeolite. Our antimony segment consists of:

Our facility located in the Burns Mining District of Sanders County in Montana that processes raw antimony ore primarily into antimony oxide, antimony metal ingots, antimony trisulfide, and precious metals, and
Our facilities in our USAMSA subsidiary located in Mexico that process raw antimony ore primarily into antimony metal ingots and a lower grade of antimony oxide.

Our zeolite segment consists of our facility located in Preston, Idaho that mines, processes, and sells zeolite.

The following components of the Company’s business were not engaged in business activities at June 30, 2026 from which they generated revenue offset by related expenses: Los Juarez, Mexico in our ADM subsidiary, Ontario, Canada, Alaska, and the mining claims in Thompson Falls, Montana. Therefore, these components, along with the Company’s personal residence for a management employee, apartment complex in Thompson Falls, Montana for hourly employees, and flotation and concentration facility located in Radersburg, Montana, have been included in the “All Other” category for segment reporting. The Company’s chief operating decision maker is its chief executive officer.

DESCRIPTION OF BUSINESS

Overview

United States Antimony Corporation began operations in Montana in January 1970 with an initial strategy centered around antimony mining and processing in Montana. Antimony mining ceased in the U.S. in the 1980’s, including our antimony mining operations in Montana, due to a significant increase of less expensive antimony ore being imported into the United States from foreign countries. However, the Company continued to process ore sourced from certain foreign suppliers into antimony oxide, metal, and trisulfide and into precious metals, primarily gold and silver, at its smelting facility in Montana. In 2025, the Company purchased certain surface rights to one of its mining claims in Montana and mined 840 tons of antimony ore. While still procuring antimony ore from foreign suppliers, the Company’s operation in Montana is once again vertically integrated with the mining of its own ore.

In the early 2000’s, the Company expanded its footprint with antimony and precious metals operations located in Mexico and zeolite operations located in Idaho. Our zeolite operations are vertically integrated from mining to selling zeolite products to its customers, which is the Company’s goal for its businesses.

Beginning in 2024 and continuing in 2025 and 2026, the Company has acquired mining claims, real properties (patented claims) and leases located in Alaska, Montana and Ontario, Canada prospective for both antimony ore and other critical minerals which have the potential to increase antimony ore throughput at the Company’s facilities, reduce the cost of third-party antimony ore purchases, expand the Company’s product offerings and diversify its mineral portfolio. The Company has also entered into certain agreements to acquire exploration rights for mining properties located in the southeastern United States. We have invested in these mining properties to further our strategy of vertical integration, expand the Company’s product portfolio, and to lower our ore cost compared to third-party antimony ore purchases. No active, revenue-producing operations have been conducted thus far in 2026 from the Company’s mining claims and leases located in Los Juarez, Mexico (our ADM subsidiary), Ontario, Canada, Alaska, and Thompson Falls, Montana. However, the Company has performed exploration activities and limited surface mining at several locations.

In January 2026, the Company completed the acquisition of a fully operational flotation and concentration facility in Radersburg, Montana for total cash consideration of $4.8 million. The Radersburg property is expected to enhance midstream processing capacity and further vertically integrate the Company’s domestic antimony supply chain. Management has budgeted approximately $2.0 million in capital expenditures to modernize equipment and add a new laboratory with the goal of optimizing operational efficiencies and mineral recovery rates.

In January 2026, the Company paid $1.3 million to purchase 36 federal mining claims located in the Koyukuk Mining District of Alaska (commonly referred to as Nolan Creek) that are prospective for antimony and gold. This agreement does not require the Company to make any royalty payments.

27

Table of Contents

In February 2026, the Company entered into a joint venture agreement with Americas Gold and Silver Corporation (“Americas”) to construct and operate a new, state-of-the-art hydrometallurgical processing facility. The Company holds a 49% membership interest, with the remaining 51% held by Americas. While the Company is responsible for managing the day-to-day activities of the joint venture, governance is shared through a management committee with equal representation from each member, and all significant decisions require unanimous approval.

On March 11, 2026, the Company’s common stock began trading on the New York Stock Exchange (“NYSE”) and continued trading on NYSE Texas. Prior to that date, the Company’s common stock was listed on the NYSE American exchange and NYSE Texas.

In March 2026, the Company was awarded a $27.0 million grant from the U.S. Department of War under the Defense Production Act to support the expansion and modernization of its domestic antimony processing facilities and to fund a portion of the Company’s Alaskan antimony mining operations. The award is milestone-based, with $16.2 million currently obligated and an additional $10.8 million subject to future authorization by the U.S. government. On March 25, 2026, the Company received approval for three project milestones representing $12.8 million of committed funding for the Thompson Falls, Montana facility expansion. Based on the achievement and approval of the related milestones, the Company recognized the grant as a reduction of property, plant and equipment during the first quarter of 2026. The related cash proceeds were received in April 2026. Additional funding under the award is contingent upon the achievement and approval of future project milestones.

On April 10, 2026, the Company published an initial assessment technical report summary on its Fostung tungsten project. This Initial Assessment-level Technical Report Summary, dated January 31, 2026 (the “Fostung TRS”), was prepared in accordance with the mining property disclosure rules specified in subpart 1300 of Regulation S-K and filed as an exhibit to the Form 8-K filed by the Company on April 10, 2026. The Fostung project was acquired by the Company in 2025 and includes 50 single-cell tungsten mining claims located in the Sudbury District of Ontario. As noted, the Fostung TRS is an Initial Assessment-level report and, accordingly, does not establish any Mineral Reserves. The report does, however, estimate 14.8 million tons of inferred mineral resources containing approximately 54.2 million pounds of tungsten. Exploration of the deposit indicates potential to expand the resource further, and preliminary test work has demonstrated the ability to improve the grade of the tungsten-bearing material through sorting.

Operations

The Company has two reportable segments: antimony and zeolite. Antimony and zeolite are minerals used in a wide range of industrial, commercial, and governmental applications, and the Company supplies these minerals in processed forms suitable for end-use applications.

Antimony Segment

Our antimony segment consists of:

Our facility located in the Burns Mining District of Sanders County in Montana that processes ore primarily into antimony oxide, antimony metal ingots, antimony trisulfide, and precious metals, and
Our two facilities in our USAMSA subsidiary located in Mexico that process ore primarily into antimony metal and a lower grade of antimony oxide.

Antimony is a mineral that is included in many products that are used every day, both by the military and industrial customers. USAC can provide this mineral in a form that can be used in these products.

Antimony is used in many products as a fire-retardant and primer and is on the Critical Minerals List of the U.S. Government. Antimony mined from the ground, which is called antimony ore or ore, is typically not salable as a finished product primarily due to impurities in the ore, the ore size not being compatible with its intended use, and the percentage of antimony contained in the ore being too low. We process ore to remove impurities, refine the size, and increase the percentage of antimony contained in the ore to approximately 71.4% to make the finished product called antimony trisulfide, to approximately 83% to make the finished product called antimony oxide, and to approximately 99.65% to make the finished product called antimony metal. Antimony trisulfide, oxide, and metal can be sold as finished products to companies in many industries as well as government agencies. 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 ore we purchase for our facility located in Montana contains antimony, gold, and silver. Our Montana facility

28

Table of Contents

processes this ore and sells the gold and silver to the company who sold us this ore, which represents all our precious metals sales, and sells the antimony to other companies in various industries. Our Mexico facilities have been processing ore primarily into antimony metal.

We estimate (but have not independently confirmed) that our present share of the domestic and international markets for antimony oxide products is approximately 4% and less than 1%, respectively. We believe we are competitive due to the following:

We are the only U.S. domestic operating, permitted processor of antimony products.
We can process ore quickly and have minimal shipping time to domestic customers.
We have a reputation for quality products delivered on a timely basis.
Our smelter in Coahuila, Mexico is the largest operating smelter for the processing of antimony products in Mexico.
We are a fully vertically integrated operation that includes mining, processing and selling antimony products. We believe there are no other companies in the world, outside of Russia or China, that can make that claim.

Zeolite Segment

Our zeolite segment includes our vertically integrated Bear River Zeolite (“BRZ”) facility located in Preston, Idaho that mines, processes, and sells zeolite. Zeolite is a mineral that is included in many products that are used every day. BRZ can provide these minerals in a form that can be used in these products. Our zeolite has been used for many purposes including water filtration, sewage treatment, nuclear waste and other environmental cleanup, odor control, gas separation, animal nutrition, soil amendment and fertilizer, and other miscellaneous applications.

On July 24, 2025, the Company published a technical report summary on its zeolite mineral deposit located in Preston, Idaho. This Technical Report Summary, dated July 2, 2025 (the “TRS”), on the Bear River Zeolite Project was prepared in accordance with the mining property disclosure rules specified in subpart 1300 of Regulation S-K. The full text of the TRS is an exhibit to the Form 8-K filed by the Company on July 25, 2025.

BRZ has a lease with Zeolite, LLC that entitles BRZ to surface mine and process zeolite on the property in Preston, Idaho, in exchange for an annual payment and a royalty payment, which is based on the amount of zeolite shipped from the leased property (“BRZ Lease”). The BRZ Lease, which was extended in 2025, currently ends on December 31, 2034. In addition, BRZ can surface mine and process zeolite on property owned by the U.S. Bureau of Land Management that is located adjacent to the Company’s Preston, Idaho property after obtaining required permits.

“Zeolite” refers to a group of industrial minerals that consist of hydrated aluminosilicates that hold cations such as calcium, sodium, ammonium, various heavy metals, and potassium in their crystal lattice. Water is loosely held in cavities in the lattice. BRZ zeolite is regarded as one of the best zeolites in the world due to its high cation exchange capacity (CEC) of approximately 180-220 meq/100 gr. (which predicts plant nutrient availability and retention in soil), its hardness and high clinoptilolite content (which is an effective barrier to prevent problematic radionuclide movement), its absence of clay minerals, and its low sodium content. Our zeolite has been used in:

Soil Amendment and Fertilizer. Zeolite has been successfully used to fertilize golf courses, sports fields, parks and common areas, and high value agricultural crops.

Water Filtration. Zeolite is used for particulate, heavy metal and ammonium removal in swimming pools, municipal water systems, industrial water discharge streams, fisheries, fish farms, and aquariums.

Mine Underground Ventilation. Zeolite is used in underground mining operations to help mitigate ammonia generated from the detonation of ammonium nitrate/fuel oil (ANFO) explosives. When ANFO explosives are detonated, ammonia can be released into the mine’s ventilation air, potentially affecting air quality for underground workers. Zeolite is employed as an absorbent material to capture ammonia from the ventilation stream, helping to reduce airborne ammonia concentrations and maintain a cleaner breathing environment for miners.

Sewage Treatment. Zeolite is used in sewage treatment plants to remove nitrogen and as a carrier for microorganisms.

Nuclear Waste and Other Environmental Cleanup. Zeolite has shown a strong ability to selectively remove strontium, cesium, radium, uranium, and various other radioactive isotopes from solution. Zeolite can also be used for the cleanup of soluble metals such as mercury, chromium, copper, lead, zinc, arsenic, molybdenum, nickel, cobalt, antimony, calcium, silver and uranium.

Odor Control. A major cause of odor around cattle, hog, and poultry feed lots is the generation of the ammonium in urea and manure. The ability of zeolite to absorb ammonium prevents the formation of ammonia gas, which disperses the odor.

Gas Separation. Zeolite has been used for some time to separate gases, to re-oxygenate downstream water from sewage plants, smelters, pulp and paper plants, and fishponds and tanks, and to remove carbon dioxide, sulfur dioxide and hydrogen sulfide from methane generators as organic waste, sanitary landfills, municipal sewage systems, animal waste treatment facilities, and is excellent in pressure swing apparatuses.

Animal Nutrition. According to third-party research, feeding up to 2% zeolite increases growth rates, decreases conversion rates, and prevents scours.

Miscellaneous Uses. Other uses include catalysts, petroleum refining, concrete, solar energy and heat exchange, desiccants, pellet binding, horse and kitty litter, floor cleaner, traction control, ammonia removal from mining waste, and carriers for insecticides, pesticides and herbicides.

a)Revenue from sales of gold and silver totaled $410,193 and $(20,539) for the six months ended June 30, 2026 and 2025, respectively, which are excluded from Revenue and Gross profit in the table above but included in the antimony segment. Pounds of antimony sold in the table above exclude the sales related to gold and silver for both periods presented.

Antimony revenue decreased $3.8 million, or 39%, and $4.1 million, or 27%, for the three and six months ended June 30, 2026, respectively, as compared to the corresponding periods in the prior year. These decreases were primarily attributable to lower market prices for antimony, which resulted in average sales prices per pound declining 52% and 27% during the three and six-month periods, respectively. The impact of lower selling prices was partially offset by a 26% increase in pounds of antimony sold during the three-month period, while sales volumes for the six-month period remained relatively consistent with the prior year.

Antimony gross profit decreased $2.7 million, or 95%, and $4.1 million, or 78%, for the three and six months ended June 30, 2026, respectively, as compared to the corresponding periods in the prior year. These decreases were primarily attributable to lower average selling prices for antimony, which reduced average gross profit per pound by 96% and 78% during the three and six-month periods, respectively. Average cost per pound declined 33% during the three-month period and remained relatively consistent with the prior year during the six-month period. Gross margin during the first six months of 2026 did not benefit from any processing of the Company’s in-house antimony mined in Montana or from any antimony deliveries under the Company’s contract with the DLA.

During June 2026, the Company fulfilled its first two shipments under the contract with the DLA. These shipments, which consisted of approximately 82,000 pounds of antimony metal ingots, were formally accepted by the DLA in July 2026. Under the terms of the contract, control transfers to the DLA when formal acceptance has occurred. As a result, the Company recognized the $2.6 million of revenue related to these shipments in July 2026, which will be included in the Company’s third-quarter financial results.

Zeolite revenue increased $972,683, or 110%, and $893,900, or 45%, for the three and six months ended June 30, 2026, respectively, as compared to the corresponding periods in the prior year. These increases were primarily attributable to tons of zeolite sold increasing 114% and 49% during the three and six-month periods, respectively, which reflected the Company’s expanded sales efforts, including additional penetration into the cattle market, as well as continued growth in its traditional industrial markets. The impact of increased sales volumes was partially offset by decreases in the average sales price per ton of 2% and 3% during the three and six-month periods, respectively.

Gross profit increased $231,156, or 189%, for the three months ended June 30, 2026, and decreased $48,026, or 16%, for the six months ended June 30, 2026, as compared to the corresponding prior-year periods. The increase in gross profit during the second quarter of 2026 was primarily attributable to the significant increase in sales volume combined with lower average production costs, which more than offset the impact of the modest decrease in the average sales price per ton. The decrease in gross profit for the six-month period was primarily attributable to higher freight costs associated with the Company’s expanded geographic distribution.

Consolidated Financial Performance:

Operating Expenses

Operating expenses increased $4.7 million and $11.4 million for the three and six months ended June 30, 2026, respectively, compared to the corresponding prior-year periods. These increases were primarily attributable to higher non-cash share-based compensation resulting from equity awards granted following shareholder approval of the Amended and Restated 2023 Equity Incentive Plan in 2025, increased salaries and employee benefits to support the Company’s expanded operations and growth initiatives, and higher professional fees associated with various strategic initiatives.

Other Income, Net

Other income, net increased $7.0 million and $3.0 million for the three and six months ended June 30, 2026, respectively, as compared to the corresponding prior-year periods. These increases were primarily attributable to unrealized gains on the Company’s investment in Larvotto of $6.8 million during the second quarter of 2026 and $2.7 million for the six-month period. The remaining increases were primarily due to higher investment income resulting from increased cash balances invested in interest-bearing accounts and securities.

Net cash used in operating activities was $20.7 million for the six months ended June 30, 2026, compared to $2.4 million in the prior year period. The increased use of operating cash was primarily driven by higher working capital requirements, including a $9.6 million increase in inventories as the Company built up its antimony inventory and a $4.5 million decrease in accounts payable, after giving effect to $1.5 million of property and equipment additions included in accounts payable at period end. Operating cash flows were also affected by a net loss of $11.2 million, partially offset by non-cash charges, including $7.7 million of share-based compensation expense and $0.9 million of depreciation and amortization expense.

Net cash used in investing activities was $11.1 million for the six months ended June 30, 2026, compared to $17.4 million in the prior year comparative period. Investing activities in the current period were primarily driven by $22.8 million of capital expenditures and $1.1 million of additional advances made to a strategic supplier under a new convertible note receivable. Capital expenditures were primarily attributable to ongoing construction associated with the expansion of the Company’s existing smelting operations in Thompson Falls, Montana, the acquisition of the Radersburg flotation mill, and other capital investments, including the acquisition of additional mining claims and machinery and equipment. These cash outflows were partially offset by $12.8 million of government grant proceeds received during the period as reimbursement for qualifying capital expenditures.

Net cash provided by financing activities was $43.4 million during the first six months of 2026 as compared to $7.3 million of net cash provided by financing activities for the prior year six-month period. Significant financing activities in 2026 have included $49.1 million of net proceeds received from the sale of common stock in “at the market offerings” and $2.0 million of proceeds received from the exercise of pre-existing common stock warrants, offset in part by $7.8 million of treasury stock purchases.

Our mission is to service our employees, customers, and vendors well and grow our business profitably both organically and through strategic acquisitions and partnerships to increase shareholder value. The Company is focused on generating cash flow to fund its mission. One method of generating cash is through the sale or issuance of common stock, warrants, debt, and other investment vehicles, which the Company has been successful at executing in the past. However, our ability to access capital or raise funds when needed is not assured and, if capital is not available when, and in the amounts and terms needed, or if capital is not available at all, the Company could be required to significantly curtail its operations, modify existing strategic plans, and/or dispose of certain operations or assets, which could materially harm our business, prospects, financial condition, and operating results.

In 2025, the Company secured a $19.0 million margin credit line with a national bank, which bears interest at one percent above the base commercial rate. Borrowings under the facility are secured by the Company’s investment in U.S. Treasury Strips, which are pledged as collateral. During the first and second quarters of 2026, the Company borrowed $5.0 million and $10.0 million, respectively, under the margin credit line, with each borrowing repaid prior to the end of the respective quarter. The Company had no outstanding borrowings

33

Table of Contents

under the margin credit line as of June 30, 2026 or December 31, 2025. Availability under the margin credit line is subject to customary margin requirements based on a percentage of the value of the pledged securities.

In March 2026, the Company was awarded a $27.0 million grant from the U.S. Department of War under the Defense Production Act to support the expansion and modernization of its domestic antimony processing facilities and to fund a portion of the Company’s Alaskan antimony mining operations. The award is milestone-based, with $16.2 million currently obligated and an additional $10.8 million subject to future authorization by the U.S. government. On March 25, 2026, the Company received approval for three project milestones representing $12.8 million of committed funding for the Thompson Falls, Montana facility expansion. Based on the achievement and approval of the related milestones, the Company recognized the grant as a reduction of property, plant and equipment during the first quarter of 2026. The related cash proceeds were received in April 2026. Additional funding under the award is contingent upon the achievement and approval of future project milestones.

The Company could also receive additional funding from the U.S. Government for initiatives related to facility expansion and critical exploration and development mining. The Company has made formal applications in 2026 to several governmental agencies for a total of $274 million. However, there is no assurance that additional U.S. Government funding will be accessible to the Company.

In addition, the Company continues to review each segment’s operational and financial results for opportunities to improve cash flow and to make informed decisions that benefit the Company overall.

As of June 30, 2026, the Company had cash and cash equivalents of $41.4 million and investments in debt securities of $20.7 million as available liquidity. We intend to fund our cash requirements with our cash and cash equivalents, cash generated from our operations, and capital raised from various investment vehicles and believe cash from these sources are sufficient to cover our requirements for the next 12 months. We intend to continue to invest in our employees, customers, infrastructure, and operations with the goals of increasing production, decreasing costs, and growing revenue profitably. We may also use our available cash to acquire businesses or additional properties. The nature of these investments and transactions, however, makes it difficult to predict the amount and timing of such future cash requirements.

ITEM 4. CONTROLS AND PROCEDURES

Conclusions of Management Regarding Effectiveness of Disclosure Controls and Procedures

At the end of the period covered by this Quarterly Report on Form 10-Q, an evaluation was carried out under the supervision and with the participation of the Company’s management, including the Principal Executive Officer (“PEO”) and Principal Financial Officer (“PFO”), of the effectiveness of the design and operations of the Company’s disclosure controls and procedures (as defined in Rule 13a – 15(e) and Rule 15d – 15(e) under the Exchange Act). Based on that evaluation, the PEO and the PFO have concluded that our disclosure controls and procedures were not effective in ensuring that: (i) information required to be disclosed by the Company in reports that it files or submits to the SEC under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in applicable rules and forms, and (ii) material information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to our management, including our PEO and PFO, as appropriate, to allow for accurate and timely decisions regarding required disclosure.

The conclusion that our disclosure controls and procedures were not effective as of June 30, 2026 is a result of the previously identified material weakness in internal control over financial reporting described in Part II, Item 9A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, which relates to insufficient qualified accounting personnel and the related design and operation of controls over the financial statement close and reporting process. Notwithstanding the material weakness, management has concluded that the unaudited condensed consolidated financial statements included in this Quarterly Report present fairly, in all material respects, the Company’s financial position, results of operations and cash flows for the periods presented in conformity with U.S. GAAP.

Management of the Company has taken proactive steps to address this material weakness by hiring employees to lead Sarbanes-Oxley compliance, SEC reporting, accounts payable, payroll, finance and accounting in Mexico and at BRZ, information technology, and the

joint venture. In addition, the Company hired a third-party firm in 2025 to assist with the implementation of new accounting software and to assist with gaining compliance with Sarbanes-Oxley, all of which is ongoing.

Changes in Internal Control over Financial Reporting

Other than the continued remediation efforts discussed above related to the design and implementation of sufficient controls and processes around internal controls over financial reporting, there have been no changes during the quarter ended June 30, 2026 in the Company’s internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, internal controls over financial reporting.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

Information regarding the Company’s legal proceedings is included in Note 16—COMMITMENTS AND CONTINGENCIES to the unaudited condensed consolidated financial statements included in this Quarterly Report.

ITEM 1A. RISK FACTORS.

There have been no material changes from the risk factors previously disclosed in the Company’s Form 10-K for the year ended December 31, 2025, which was filed with the SEC on March 19, 2026, except as described below.

The Company’s receipt of funds under its Department of War award is subject to significant conditions, and failure to satisfy these conditions or obtain continued authorization could adversely impact its operations and financial condition. In March 2026, the Company was awarded up to $27.0 million in funding from the U.S. Department of War under the Defense Production Act, administered through the Defense Industrial Base Consortium (“DIBC”), to support the expansion and modernization of its domestic antimony processing operations. The award is structured as a milestone-based arrangement, with $16.2 million currently obligated and the remaining $10.8 million subject to future authorization at the discretion of the U.S. government. Payments are contingent upon the Company achieving specified project milestones, obtaining formal government approval of such milestones, and complying with ongoing requirements, including environmental, reporting, and project execution obligations.

There can be no assurance that the Company will successfully complete all required milestones, maintain compliance with all applicable conditions, or receive approval for additional funding. Any failure to meet these requirements, delays in milestone achievement or approval, changes in government priorities, or termination or modification of the agreement could result in a delay, reduction, or forfeiture of expected funding. In addition, the Company is required to fund a portion of the project costs, and if anticipated grant proceeds are not received in a timely manner or at all, the Company may be required to obtain alternative sources of financing or delay planned capital expenditures.

The Company’s financing and commercial arrangement with a key antimony supplier exposes us to credit, operational, and supply chain risks. We have entered into a commercial antimony sourcing arrangement with a supplier as part of our strategy to support and expand our antimony supply chain. This arrangement is supported by a $4.0 million Convertible Promissory Note (the “Convertible Note”) that is secured by substantially all assets of the supplier and supported by a personal guaranty from the supplier’s principal owner. While these protections are intended to mitigate our credit exposure, there can be no assurance that the supplier will have sufficient liquidity, operational capacity, or financial resources to satisfy its obligations under the note or related commercial agreements.

If the international supplier experiences financial distress, operational difficulties, liquidity constraints, regulatory challenges, equipment failures, or other adverse developments, it may be unable to repay amounts owed to us, deliver anticipated antimony products, or otherwise perform under its contractual obligations. In such circumstances, we could incur losses associated with the note receivable, experience delays or disruptions in anticipated antimony supply, incur additional costs to obtain alternative sources of supply, or be required to devote additional resources to enforcing our contractual rights.

In addition, although the Convertible Note provides us with the right to convert indebtedness into membership interests of the supplier, it is a privately held company and there can be no assurance that any equity interests received upon conversion would have a readily realizable value or provide a recovery equivalent to the amounts owed under the note. Any of these events could adversely affect our business, financial condition, results of operations, cash flows, and growth strategy.

The Company’s significant inventory position in Mexico may expose us to operational, inventory valuation, and liquidity risks. The Company maintains a significant inventory of antimony materials at its facilities in Mexico. The ultimate realization of the value of this inventory depends upon our ability to efficiently process these materials into finished products that meet applicable customer specifications in a commercially acceptable and timely manner. Processing results may be affected by numerous factors, including the characteristics of the raw materials, recovery rates, production yields, equipment performance, operating efficiencies, and other manufacturing variables.

If we are unable to process these materials as anticipated, or if processing requires additional time, costs, or modifications to our production methods, the inventory may remain on hand longer than expected, resulting in increased carrying costs, reduced liquidity, and higher working capital requirements. In addition, if market prices for antimony continue to decline while such inventory remains on hand, or if the estimated net realizable value of the inventory falls below its carrying value for any reason, we may be required to recognize inventory write-downs, which could adversely affect our gross margins, operating results, financial condition, and cash flows.

Any significant delay or inability to convert this inventory into finished products that satisfy customer requirements could materially and adversely affect our business, financial condition, results of operations, and cash flows.
