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 processes third party ore primarily into antimony oxide, antimony metal, 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 is used in bearings, storage batteries, and ordnance. Antimony trisulfide is used as a primer in ammunition. At its Bear River Zeolite (“BRZ”) facility located in Idaho, the Company mines and processes zeolite, a group of industrial minerals used in water filtration, sewage treatment, nuclear waste and other environmental cleanup, odor control, gas separation, animal nutrition, soil amendment and fertilizer, and other miscellaneous applications. In 2024 and 2025, the Company leased a metals concentration facility located in Montana and began acquiring mining claims and leases located in Alaska, Montana and Ontario, Canada, in an effort to expand its operations as well as its product offerings.

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, 2025, and its results of operations and cash flows for the three and six months ended June 30, 2025 and 2024. The Condensed Consolidated Balance Sheet as of December 31, 2024, 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/A for the year ended December 31, 2024, filed with the Securities and Exchange Commission on April 18, 2025.

This summary of significant accounting policies of the Company is presented to assist in understanding the Company’s financial statements. These accounting policies conform to U.S. GAAP and have been consistently applied in the preparation of the financial statements.

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, 2025, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2025.

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.

Investment Securities Held to Maturity

The Company purchased short-term and long-term investment grade U.S. Treasury Strips in the second quarter of 2025 in an effort to protect itself from anticipated interest rate drops. These securities are classified as held-to-maturity and carried at amortized cost because the Company has both the intent and ability to hold them until their contractual maturity date. Since these U.S. Treasury Strips are zero-coupon instruments that do not pay periodic interest, the original investment amount is adjusted for the accretion of discounts using the effective interest method over the period from acquisition to maturity. Discount accretion is recognized as “Interest and investment income” in the Condensed Consolidated Statements of Operations.

Consistent with the Company’s classification of its U.S. Treasury Strips as held to maturity, those securities scheduled to mature in the next twelve months after the reporting date are considered current assets and those having maturity dates more than twelve months after the applicable reporting date are considered non-current assets. Unrealized gains and losses on held-to-maturity securities are not recognized in the Company’s condensed consolidated financial statements. Instead, these amounts are closely monitored and disclosed in the footnotes to the condensed consolidated financial statements.

The Company accounts for credit losses on its held-to-maturity securities in accordance with the expected credit loss model, as prescribed by U.S. GAAP. An allowance for credit losses is recognized to reflect the Company's estimate of expected credit losses over the contractual life of its held-to-maturity securities. In accordance with the accounting guidance prescribed for credit losses on held-to-maturity debt securities, the Company has presumed the expected credit losses on its U.S. Treasury Strips are negligible since they are explicitly guaranteed by the U.S. government.

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures, amending income tax disclosure requirements for the effective tax rate reconciliation and income taxes paid. The amendments in this ASU are effective for fiscal years beginning after December 15, 2024 and are applied prospectively. Early adoption and retrospective application of the amendments are permitted. These new disclosure requirements will be effective in the Company’s Annual Report on Form 10-K for the fiscal year ending December 31, 2025. Other than the new disclosure requirements, this guidance is not expected to have an impact on the Company’s consolidated financial statements.

In November 2024, 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. These new disclosure requirements are effective for the Company's annual periods 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.

The Company does not believe that issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s 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:

The potentially dilutive common stock equivalents not included in the calculation of diluted earnings per share as their effect would have been anti-dilutive were as follows:

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.

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 securities, and debt obligations.

The carrying amounts of cash and cash equivalents approximate fair value because of its short-term nature. The estimated fair values of investment securities held to maturity were based on Level 2 inputs. 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.

NOTE 5 – REVENUE RECOGNITION

The Company’s products consist of the following:

Sales by product type for the three and six months ended June 30, 2025 and 2024 were as follows:

Domestic and foreign revenues for the three and six months ended June 30, 2025 and 2024 were as follows:

The Company’s trade accounts receivable balance related to contracts with customers was $2,543,413 at June 30, 2025 and $1,156,564 at December 31, 2024, which is net of an allowance for credit losses of $11,049 and $10,165 at June 30, 2025 and December 31, 2024, respectively. The Company’s products do not involve any warranty agreements and product returns are not typical.

NOTE 6 – INVESTMENT SECURITIES HELD TO MATURITY

In April 2025, the Company purchased $9,991,259 of U.S. Treasury Strips with maturities ranging from approximately 12 to 54 months. These U.S. Treasury Strips are scheduled to mature approximately equally about every six months beginning in May 2026 and will generate interest yields of approximately 4%.

The Company has classified these securities as held-to-maturity because it has the intent and ability to hold them until their contractual maturity date. As a result, these securities are carried at amortized cost, which represents the original investment amount adjusted for the amortization of discounts using the effective interest method over the period from acquisition to maturity.

The following is a summary of the Company’s investment securities held to maturity as of June 30, 2025:

The Company recognized interest income accretion on its U.S. Treasury Strips of $95,990 during both the three and six months ended June 30, 2025. There were no investment securities outstanding at December 31, 2024 or held during the six months ended June 30, 2024.

Consistent with the Company’s classification of its U.S. Treasury Strips as held to maturity, those securities scheduled to mature in the next twelve months after the reporting date are considered current assets and those having maturity dates more than twelve months after the reporting date are considered non-current assets. At June 30, 2025, the Company’s held to maturity securities were scheduled to mature as follows:

Line of Credit

The Company secured a $5,000,000 line of credit facility (“LOC”) in April 2025, which bears interest at one percent above the base commercial rate. The Company’s investment securities serve as collateral for the LOC on which the Company had no outstanding borrowings at June 30, 2025.

NOTE 7 – INVENTORIES

Inventories at June 30, 2025 and December 31, 2024 consisted primarily of finished antimony metal 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. Finished antimony products and finished zeolite products primarily include direct materials, direct labor, overhead, depreciation, and freight. Inventories at June 30, 2025 and December 31, 2024 were as follows:

At June 30, 2025 and December 31, 2024, inventories were valued at cost, except for the portion of inventory related to zeolite at December 31, 2024, which was valued at net realizable value because costs were greater than the amount the Company expected to receive upon the sale of the inventory. The adjustment to value zeolite inventory at net realizable value was $65,647 at December 31, 2024.

Antimony oxide, metal, and ore and concentrates were held primarily at the Company’s plants located in Montana and Mexico. Some antimony metal is used in processing antimony ore into antimony oxide. Zeolite inventory was held at the Company’s plant located in Idaho.

NOTE 8 – PROPERTY, PLANT AND EQUIPMENT

The major components of the Company’s property, plant and equipment (“PP&E”) by segment at June 30, 2025 and December 31, 2024 were as follows:

In February 2025, the Company purchased a personal residence located near its operations in Thompson Falls, Montana for $445,000, which is presently being used by management personnel that were transferred there and are now working in Montana predominantly on our expansion efforts. This asset and related expenses are included in the “All Other” category in the Company’s segment reporting.

Mineral rights and interests

In January 2025, the Company executed an agreement to acquire the ownership rights to one hundred and twenty mining claims located in the Fairbanks District of Alaska (“January Fairbanks Agreement”). Payments to acquire these claims have been or will be made by the Company on or around the payment dates indicated as follows:

The January Fairbanks Agreement requires a royalty payment by the Company based on the actual production from the claims (“Net Smelter Royalty on Claims”) and another royalty payment by the Company based on the actual production, if any, from certain areas surrounding these one hundred and twenty mining claims (“Net Smelter Royalty on Surrounding Area”). A certain percentage of the Net Smelter Royalty on Claims can be purchased back by the Company with certain factors causing an escalation in this buyback amount. Also, the January Fairbanks Agreement includes a commitment by the Company to spend an aggregate of $2,250,000 on exploring and developing these claims over five years beginning January 2025, with various milestones over this five-year period. The January Fairbanks Agreement can be terminated without cause at any time by the Company with notice.

In March 2025, the Company executed an agreement to acquire the ownership rights to twenty-five additional mining claims and leases located in the Fairbanks District of Alaska (“March Fairbanks Agreement”). Payments to acquire these claims and leases have been or will be made by the Company on or around the payment dates indicated as follows:

The March Fairbanks Agreement requires a royalty payment by the Company based on the actual production from the claims and leases (“Net Smelter Royalty”). A certain percentage of the Net Smelter Royalty can be purchased back by the Company. Also, the March Fairbanks Agreement includes a commitment by the Company to spend an aggregate of $250,000 on exploring and developing these claims and leases over approximately forty-one months beginning March 2025, with various milestones over this period. The March Fairbanks Agreement can be terminated without cause by the Company with notice.

In May 2025, the Company paid $230,000 to acquire the surface rights related to its patented lode mining claim located in Thompson Falls, Montana.

In June 2025, the Company acquired property located in the Sudbury District of Ontario, Canada, which included 50 single-cell mining claims (the Fostung Properties) for $5,000,000. Direct transaction costs related to this acquisition totaled $25,120. In addition, the agreement requires the Company to pay a net smelter return royalty based on actual production from the property.

Effective June 1, 2025, the Company executed an agreement to acquire the ownership rights to various patented federal lode mining claims located in the Fairbanks District of Alaska (“June Fairbanks Agreement”). Payments to acquire these claims are scheduled to be made by the Company as follows:

The June Fairbanks Agreement requires net smelter royalty payments be made by the Company based on actual production from the claims. Also, the agreement includes a commitment by the Company to spend an aggregate of $700,000 in exploring and developing these claims based on various milestones scheduled to occur over approximately thirty-nine months from the effective date of the agreement. This agreement can be terminated without cause at any time by the Company with ninety-days’ notice.

The payments made to acquire these mining claims and leases, including any direct transaction costs, are capitalized in the “Mineral rights and interests” component of “Property, plant and equipment, net” in the Condensed Consolidated Balance Sheets and included in the “All Other” category for segment reporting.

NOTE 9 – 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 this lease in March 2025 extending the term of the lease to September 2, 2026 and modifying the fixed monthly lease payments to $10,000 per month through the month of June 2025, $20,000 per month during the months of July 2025 to October 2025, and $95,000 per month thereafter to the end of the lease term. The $95,000 per month payment includes a fixed monthly fee of $45,000 and a minimum milling fee of $50,000 per month. An additional payment of $50 per ton is due each month in the last twelve months of the lease for all milling in excess of 1,000 tons per month. The Company has not included any milling fee payments above the minimum in its lease liability as it is not deemed probable at this time. The Company recorded the present value of the original fixed lease cost in September 2024 over the lease term as a lease liability and Right of Use ("ROU") asset. As a result of the amendment in March 2025, the Company reduced the ROU asset and corresponding lease liability by $37,448. The Company used its incremental borrowing rate of 3.49% when determining the present value of future payments of this operating lease as the rate implicit in the lease was not readily determinable. The lease includes provisions for the Company to use the existing mill building and all contents related to its use and to process owned and non-owned ore containing antimony and other minerals. The lease does not include any transfer of ownership of the facility at the end of the lease, nor any option to extend the lease or purchase the facility, nor any residual value guarantees. The Company can terminate the lease without cause with thirty days’ notice and must provide the facility to the lessor at the end of the lease in the same condition as it was received.

The lease liability related to this operating lease, which represents the present value of the lease payments, was $701,557 at inception of the lease amendment and $664,817 and $755,569 at June 30, 2025 and December 31, 2024, respectively. The ROU asset, which includes the unamortized portion of initial direct costs (“IDC”) and is adjusted for any accrued or prepaid lease, was $230,027 and $565,289 at June 30, 2025 and December 31, 2024, respectively. 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 and IDC in "Cost of Revenues" in the Condensed Consolidated Statements of Operations. Lease payments were $40,000 and $70,000 during the three and six months ended June 30, 2025, respectively, which were included in operating cash flows. For the three and six months ended June 30, 2024, there were no payments made or expense recorded for this lease.

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 andtotal 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's incremental borrowing rate of 3.49% was used as the discount rate as 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.

The lease liability related to this operating lease, which represents the present value of the lease payments, and ROU asset were $63,416 at inception of the lease and $45,600 and $nil at June 30, 2025 and December 31, 2024, respectively. During the three and six months ended June 30, 2025, the Company recorded $11,835 and $19,725, respectively, of lease expense related to this lease in “General and administrative” in the Condensed Consolidated Statements of Operations. Lease payments were $11,835 and $19,725 during the three and six months ended June 30, 2025, respectively, which were included in operating cash flows. The Company made a security deposit payment of $3,945 at the inception of the lease. For the three and six months ended June 30, 2024, there were no payments made or expense recorded for this lease.

The following table summarizes expense and cash payments for both operating leases during the periods noted:

At June 30, 2025, the weighted average remaining lease term of operating leases was 14 months and the weighted average discount rate for operating leases was 3.49%.

The following table is a maturity analysis of the future minimum lease payments for operating leases as of June 30, 2025:

NOTE 10 – LONG-TERM DEBT

Long-term debt at June 30, 2025 and December 31, 2024 was as follows:

At June 30, 2025, principal payments on debt were due as follows:

NOTE 11 – INCOME AND OTHER TAXES

Management estimates that the Company’s 2025 effective tax rate will be 0% due to the Company’s cumulative loss position, historical net operating losses, and other available evidence related to the Company’s ability to generate taxable income. Accordingly, there is no income tax expense or benefit recorded for the three- and six-month periods ended June 30, 2025.

Mexico Tax Assessment

In 2015, the Mexican tax authority (“SAT”) initiated an audit of the U.S. Antimony de Mexico, S.A. de C.V. (“USAMSA”) 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.

As of December 31, 2023, the updated SAT assessment was approximately $22.4 million pesos, or approximately $1,320,000 USD, which includes $352,000 of unpaid income taxes and $968,000 of interest and penalties. Management, along with its legal counsel, assessed the possible outcomes for this tax audit and believed, based on discussions with its attorneys located in Mexico, that the most likely outcome would be that the Company would be successful in its appeal resulting in no tax due. Management determined that no amount should be accrued at December 31, 2023 relating to this potential tax liability.

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, on which the appellate court has not ruled. These rulings support the Company’s position on this tax matter and have had no impact on the Company’s financial statements.

Mexico Import Value Added Tax

USAMSA has a receivable of $1,346,690 and $907,408 at June 30, 2025 and December 31, 2024, respectively, related to Import Value Added Tax (“IVA tax” or “VAT”) it pays on certain goods and services, which represents the amounts to be reimbursed from the Mexican government. USAMSA also has established an allowance for estimated uncollectible amounts associated with this IVA tax receivable of $785,018 and $575,151 at June 30, 2025 and December 31, 2024, respectively. The net IVA tax receivable of $561,672 and $332,257 at June 30, 2025 and December 31, 2024, respectively, is recorded in “IVA receivable and other assets, net” in the Condensed Consolidated Balance Sheets.

NOTE 12 – COMMITMENTS AND CONTINGENCIES

Historically, BRZ has from time to time been assessed fines and penalties by the Mine Safety and Health Administration (“MSHA”). During the six months ended June 30, 2025, BRZ received three citations from MSHA, one of which was significant and substantial. All three citations were rectified by BRZ and terminated by MSHA on the day the citations were issued. At June 30, 2025 and December 31, 2024, BRZ had “accrued liabilities” in the Condensed Consolidated Balance Sheets of $4,827 and $19,074, respectively, relating to MSHA citations.

BRZ has a lease 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”). In February 2025, the Company extended the BRZ Lease through December 31, 2034 with similar terms and conditions as the prior agreement.

In April 2025, the Company began contracting for engineering and construction services to expand its existing smelting operations located in Thompson Falls, Montana. Total capital expenditures associated with the expansion plans are estimated to be approximately $17,000,000 of which approximately $4,500,000 has been formally agreed to with various third-party vendors.

NOTE 13 – STOCKHOLDERS’ EQUITY

Issuance of Common Stock

During the six months ended June 30, 2025 and 2024, the Company issued 1,472,097 shares and 791,667 shares, respectively, of its common stock in conjunction with the vesting of restricted stock units (“RSUs”) and exercising of stock options. See the “Share-Based Compensation” section below for further details.

Sale of Common Stock

During the six months ended June 30, 2025, the Company sold 1,857,923 shares of its common stock in an “at the market offering” and received gross proceeds of $5,158,787 based on a weighted average price of $2.78 per share. Direct issuance costs totaling $94,304 were incurred related to these sales. The Company did not sell any of its common stock during the six months ended June 30, 2024.

The Company also issued 2,919,643 shares of its common stock in the first six months of 2025 related to the exercise of pre-existing warrants. See the “Common Stock Warrants” section below for further details.

Share-based compensation

In December 2023, the shareholders of the Company approved our 2023 Equity Incentive Plan (“the Plan”), which provides for the grant of incentive stock options, 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 our development and financial success, and to encourage them to devote their best efforts to our business, thereby advancing our interests and the interests of our shareholders. During the six months ended June 30, 2025, the Company granted stock options and RSUs totaling 757,300 and 654,600, respectively, pursuant to the Plan. Once vested, each stock option and RSU represent the right to receive one share of the Company’s common stock. The maximum number of shares of common stock available for issuance in connection with stock options, RSUs, and other awards granted under the Plan is 8,700,000.

Share-based compensation expense for the periods noted was as follows:

The following table summarizes the aggregate non-cash stock-based compensation recognized in the Condensed Consolidated Statement of Operations for stock options and RSUs:

Stock options

Stock options granted have either a 3-year or 10-year contractual term and are subject to either service or performance-based vesting conditions. The following table summarizes the weighted-average assumptions used to value stock options granted during the six months ended June 30, 2025 using the Black-Scholes method:

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.

Activity with respect to stock options is summarized as follows:

At June 30, 2025, total unrecognized share-based compensation expense related to stock options was $1,496,779, which is expected to be recognized over a weighted-average remaining period of 1.9 years. During the six months ended June 30, 2025,622,500 stock options were exercised to purchase shares of common stock. These exercises included 250,000 options for cash proceeds of $55,000 and cashless exercises where 50,269 shares of common stock were surrendered to the Company to pay for the aggregate exercise price of the stock options and 322,231 shares of common stock were issued. The total intrinsic value of the 622,500 stock options exercised during the six months ended June 30, 2025 was $1,061,033.

Restricted stock units

Activity with respect to RSUs is summarized as follows:

At June 30, 2025, total unrecognized share-based compensation expense related to RSUs was $1,382,688, which is expected to be recognized over a weighted-average remaining period of 2.1 years. The weighted-average remaining contractual term of the nonvested RSU shares was 1.4 years at June 30, 2025.

Common stock warrants
