NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE SIX MONTHS ENDED JUNE 30, 2025 AND 2024

Note 1 – Organization and Basis of Presentation

Organization and Line of Business

US Nuclear Corp., formerly known as APEX 3, Inc., (the “Company” or “US Nuclear”) was incorporated under the laws of the State of Delaware on February 14, 2012.

On May 31, 2016, the Company entered into an Asset Purchase Agreement with Electronic Control Concepts (“ECC”) whereby the Company purchased certain tangible and intangible assets of ECC.

The Company is engaged in developing, manufacturing, and selling radiation detection and measuring equipment. The Company markets and sells its products to consumers throughout the world.

Interim financial statements

The unaudited interim financial statements included herein, presented in accordance with United States generally accepted accounting principles and stated in US dollars, have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosure normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosure is adequate to make the information presented not misleading.

These statements reflect all adjustment, consisting of normal recurring adjustments, which, in the opinion of management, are necessary for fair presentation of the information contained therein. It is suggested that these interim financial statements be read in conjunction with the financial statements of the Company for the year ended December 31, 2024, and notes thereto included in the Company’s annual report on Form 10-K filed on June 25, 2025. The Company follows the same accounting policies in the preparation of interim reports. Results of operations for the interim period are not indicative of annual results.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The Company recorded a net loss of $768,031 for the six months ended June 30, 2025, and had an accumulated deficit of $20,560,940 as of June 30, 2025, which raises substantial doubt about its ability to continue as a going concern.

The Company’s ability to continue as a going concern is dependent upon its ability to generate profitable operations in the future and/or obtain the necessary financing to meet its obligations and repay its liabilities arising from normal business operations when they come due. Management has plans to seek additional capital through some private placement offerings of debt and equity securities. These plans, if successful, will mitigate the factors which raise substantial doubt about the Company’s ability to continue as a going concern. These consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification of liabilities that might result from this uncertainty.

Note 2 – Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Optron Scientific Company, Overhoff Technology Corporation (“Overhoff”), and its wholly-owned subsidiary, Electronic Control Concepts (“ECC”), have been prepared in conformity with accounting principles generally accepted in the United States of America. All significant intercompany transactions and balances have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. It is possible that accounting estimates and assumptions may be material to the Company due to the levels of subjectivity and judgment involved.

US NUCLEAR CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE SIX MONTHS ENDED JUNE 30, 2025 and 2024

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and cash in time deposits, certificates of deposit and all highly liquid debt instruments with original maturities of three months or less. There were no cash equivalents as of June 30, 2025, and December 31, 2024.

Concentration of Credit Risk

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist of cash and cash equivalents. The Company places its cash with high quality financial institutions and at times may exceed the FDIC insurance limit. The Company has not and does not anticipate incurring any losses related to this credit risk.

Accounts Receivable

The Company maintains reserves for potential credit losses for accounts receivable. Management reviews the composition of accounts receivable and analyzes historical bad debts, customer concentrations, customer credit worthiness, current economic trends and changes in customer payment patterns to evaluate the adequacy of these reserves. Reserves are recorded based on the Company’s historical collection history in addition to an analysis of future potential credit losses. Management considers the aging of accounts receivable, changes to customer credit ratings, as well as any industry-specific factors and economic growth trends that could impact credit loss estimates. Allowance for doubtful accounts as of June 30, 2025, and December 31, 2024 were $6,590 and $6,590, respectively.

Inventories

Inventories are valued at the lower of cost (determined primarily by the average cost method) or net realizable value. Management compares the cost of inventories with the net realizable value and allowance is made for writing down their inventories to net realizable value, if lower. As of June 30, 2025, and December 31, 2024, the Company recorded $37,351 and $37,351, respectively, in allowance for slow moving or obsolete inventory. The Company periodically assessed its inventory for slow moving and/or obsolete items. If any are identified an appropriate allowance for those items is made and/or the items are deemed to be impaired.

Property and Equipment

Property and Equipment are stated at cost. Expenditures for maintenance and repairs are charged to earnings as incurred; additions, renewals and betterments are capitalized. When equipment is retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts, and any gain or loss is included in operations. Depreciation of equipment is provided using the straight-line method for substantially all assets with estimated lives as follows:

Furniture and fixtures		5 years
Leasehold improvement		Lesser of lease life or economic life
Equipment		5 years
Computers and software		5 years

US NUCLEAR CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE SIX MONTHS ENDED JUNE 30, 2025 and 2024

Long-Lived Assets

The Company applies the provisions of Accounting Standards Codification (“ASC”) Topic 360, Property, Plant, and Equipment, which addresses financial accounting and reporting for the impairment or disposal of long-lived assets. ASC 360 requires impairment losses to be recorded on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts. In that event, a loss is recognized based on the amount by which the carrying amount exceeds the fair value of the long-lived assets. Loss on long-lived assets to be disposed of is determined in a similar manner, except that fair values are reduced for the cost of disposal. Based on its review at June 30, 2025, and December 31, 2024, the Company believes there was no impairment of its long-lived assets.

Goodwill

Goodwill represents the excess of the purchase price over the underlying net assets of businesses acquired. The entire goodwill balance in the accompanying financial statements resulted from the Company’s acquisition of Overhoff Technology Corporation in 2006. The Company complies with ASC 350, Goodwill and Other Indefinite Lived Intangible Assets, requiring that an impairment test be performed at least annually. As of June 30, 2025, and December 31, 2024, the Company performed the required impairment analysis, resulting in no impairment adjustments. Significant estimates used in the goodwill impairment analysis may change in the upcoming year if revenues do not rebound and the cost of materials continues to increase.

Investments

The Company accounts for investments in equity securities without a readily determinable fair value at cost, minus impairment. If the Company identifies observable price changes in orderly transactions for the identical or a similar investment of the same issuer, the Company measures the equity security at fair value as of the date that the observable transaction occurred (“the measurement alternative”) in accordance with ASC 321. The Company accounts for investments for which it owns 20% or more, but less than 50% on the equity method in accordance with ASC 323.

Derivative Financial Instruments

The Company evaluates all of its agreements to determine if such instruments have derivatives or contain features that qualify as embedded derivatives. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. For stock-based derivative financial instruments, the Company uses a weighted-average Black-Scholes-Merton option pricing model to value the derivative instruments at inception and on subsequent valuation dates. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative instrument liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement of the derivative instrument could be required within 12 months of the balance sheet date. During the six months ended June 30, 2025, and December 31, 2024, there were no derivative liabilities associated with our convertible notes payable.

Fair Value of Financial Instruments

For certain of the Company’s financial instruments, including cash, accounts receivable, accounts payable, accrued liabilities, customer deposits, and line of credit, the carrying amounts approximate their fair values due to their short maturities. In addition, the Company has a note payable to a shareholder that the carrying amount also approximates fair value.

Convertible Preferred Stock

The Company has authorized 10,000 shares of Series A Convertible Preferred Stock, each share convertible into 10,000 shares of the Company’s common stock. The preferred stock carries a dividend rate of 6% per annum, payable quarterly within 90 days of the applicable quarter, and 1,200 shares of common stock for each share of Series A titled to each holder. At any time after January 31, 2026, the Company has the right, but is not obligated, to call and redeem any outstanding Series A Preferred for $1,000 per share or to convert each share of Series A Preferred into 10,000 common shares. The Series A Convertible Preferred mature on January 31, 2028, at which time the Company shall convert all Series A Preferred into 10,000 common shares per Preferred.

US NUCLEAR CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE SIX MONTHS ENDED JUNE 30, 2025 and 2024

The Company relied upon guidance and accounted for the Series A Convertible Preferred in accordance with ASC 480 and ASC 470 and determined that the Series A Preferred shares would be considered equity transactions. Except for the dividends, the only mandatory payments are the conversions at maturity, however since the conversions are settled in the Company’s own common stock, the Series A Preferred do not meet the criteria for liability classification. The Company also considered the requirement to classify the Series A Convertible Preferred as temporary equity; however, the Series A shares are not redeemable at the holder’s discretion. The Call option rests solely with management of the Company and the mandatory redemption does not necessitate cash payment since the Company has the option to settle in common stock. The Company considered it highly unlikely that it would redeem the shares for cash at maturity. In addition, extinguishment of debt transactions with related parties are considered to be capital transactions.

Treasury Stock

The company may, from time to time, re-acquire its own issued and outstanding common or preferred stock. Reacquired shares are designated as treasury shares and are recorded at the cost of the shares surrendered. Treasury shares are not considered an asset; rather, they are presented as a deduction from total stockholders’ equity on the balance sheet. The company accounts for treasury share transactions using the Par Value Method in accordance with ASC 505-30. (See Note 9)

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, “Distinguishing Liabilities from Equity” (“ASC 480”) and ASC 815, “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded as liabilities at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations.

The Company considers the dilutive effect of warrants in its calculation of diluted EPS using the treasury stock method. However, the calculation excludes any warrants that are anti-dilutive.

Revenue Recognition

Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“Topic 606”), became effective for the Company on January 1, 2018. The Company’s revenue recognition disclosure reflects its updated accounting policies that are affected by this new standard. The Company applied the “modified retrospective” transition method for open contracts for the implementation of Topic 606. As sales are and have been primarily from the sale of products to customers, and the Company has no significant post-delivery obligations, this new standard did not result in a material recognition of revenue on the Company’s accompanying consolidated financial statements for the cumulative impact of applying this new standard. The Company made no adjustments to its previously reported total revenues, as those periods continue to be presented in accordance with its historical accounting practices under Topic 605, Revenue Recognition.

Revenue from the product sales is recognized under Topic 606 in a manner that reasonably reflects the delivery of its products to customers in return for expected consideration and includes the following elements:

●

executed contracts with the Company’s customers that it believes are legally enforceable;

●

identification of performance obligations in the respective contract;

●

determination of the transaction price for each performance obligation in the respective contract;

●

allocation the transaction price to each performance obligation; and

●

recognition of revenue only when the Company satisfies each performance obligation.

US NUCLEAR CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE SIX MONTHS ENDED JUNE 30, 2025 and 2024

These five elements, as applied to each of the Company’s revenue categories, are summarized below:

●

Product sales - revenue is recognized when the Company performs its obligations under the contracts it has with its customers to deliver products at an agreed upon price and it is generally when the control of the product has been transferred to the customer.

Payments received before all of the relevant criteria for revenue recognition are satisfied are recorded as customer deposits.

Sales returns and allowances were $0 and $0 for the six months ended June 30, 2025, and 2024, respectively. The Company provides a one-year warranty on all sales. Warranty expense for the six months ended June 30, 2025, and 2024 was insignificant. The Company does not provide unconditional right of return, price protection or any other concessions to its customers.

See Notes 11 and 12 for disclosures of revenue disaggregated by geographical area and product line.

Customer Deposits

Customer deposits represent cash paid to the Company by customers before the product has been completed and shipped and are considered fully refundable.

Income Taxes

The Company accounts for income taxes in accordance with ASC Topic 740, Income Taxes. ASC 740 requires a company to use the asset and liability method of accounting for income taxes, whereby deferred tax assets are recognized for deductible temporary differences, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all of, the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

Under ASC 740, a tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The adoption had no effect on the Company’s consolidated financial statements.

Stock-Based Compensation

The Company records stock-based compensation in accordance with FASB ASC Topic 718,” Compensation – Stock Compensation.” FASB ASC Topic 718 requires companies to measure compensation cost for stock-based employee compensation at fair value at the grant date and recognize the expense over the employee’s requisite service period. The Company recognizes in the statement of operations the grant-date fair value of stock options and other equity-based compensation issued to employees and non-employees.

Basic and Diluted Earnings Per Share

Earnings per share is calculated in accordance with ASC Topic 260, Earnings Per Share. Basic earnings per share (“EPS”) is based on the weighted average number of common shares outstanding.

US NUCLEAR CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE SIX MONTHS ENDED JUNE 30, 2025 and 2024

Diluted EPS is based on the assumption that all dilutive convertible shares and stock warrants were converted or exercised. Dilution is computed by applying the treasury stock method. Under this method, options and warrants are assumed to be exercised at the beginning of the period (or at the time of issuance, if later), and as if funds obtained thereby were used to purchase common stock at the average market price during the period. For periods in which the Company has reported net loss, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders, because dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.

Segment Reporting

FASB ASC Topic 280, Segment Reporting, requires use of the “management approach” model for segment reporting. The management approach model is based on the way a company’s management organizes segments within the company for making operating decisions and assessing performance. The Company determined it has two reportable segments. See Note 11.

Related Parties

The Company accounts for related party transactions in accordance with ASC 850, Related Party Disclosures. A party is considered to be related to the Company if the party directly or indirectly or through one or more intermediaries, controls, is controlled by, or is under common control with the Company. Related parties also include principal owners of the Company, its management, members of the immediate families of principal owners of the Company and its management and other parties with which the Company may deal if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests. A party which can significantly influence the management or operating policies of the transacting parties or if it has an ownership interest in one of the transacting parties and can significantly influence the other to an extent that one or more of the transacting parties might be prevented from fully pursuing its own separate interests is also a related party.

Reclassifications

Certain prior period amounts were reclassified to conform to the manner of presentation in the current period. These reclassifications had no effect on the net loss or shareholders’ equity.

Recent Accounting Pronouncements

In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which is intended to simplify how companies measure credit losses on short-term accounts receivable and contract assets. The amendments in the ASU add a practical expedient, whereby a company assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. The new standard is effective for annual reporting periods beginning after December 31, 2025, and interim reporting periods withing those annual reporting periods, with early adoption permitted. The Company is currently evaluating the new standard and does not expect this ASU to have a material effect on the Company’s consolidated financial statements and related disclosures.

MIFTEC

On August 3, 2018, the Company closed an agreement by and among, MIFTEC Laboratories, Inc. (“MIFTEC”), a licensee of Magneto-Inertial Fusion Technologies, Inc., (“MIFTI”), and the Company. MIFTEC is a licensee of MIFTI radionuclide technology. MIFTEC will engage the Company to manufacture equipment pursuant to MIFTEC’s specifications and designs and have the Company as a sales representative for the manufactured equipment. The Company will be the exclusive manufacturer and supplier to MIFTEC of equipment in North America and Asia. In addition, the Company received a 10% ownership interest in MIFTEC. The consideration for the exclusive manufacturing rights and a 10% ownership interest in MIFTEC was $500,000 and 300,000 shares of the Company’s common stock valued at $594,000. The fair value was determined based on the Company’s stock price on August 3, 2018. The Company recorded the value of the 10% interest in MIFTEC at $10,000 and recorded $1,084,000 as the acquisition of manufacturing and supply rights in the accompanying consolidated statement of operations during the year ended December 31, 2018. The Company evaluated this investment for impairment and determined that an impairment of $9,000 was necessary during the year ended December 31, 2019. The carrying value of this investment at June 30, 2025 and 2024 was $1,000 and $1,000, respectively.

MIFTI

In April 2019, the Company also entered into a Cooperative Agreement with MIFTI whereby the Company acquired certain exclusive manufacturing and supply rights, including thermonuclear fusion-powered reactor for production of electricity per MIFTI designs in return for $500,000, of which $100,000 is payable upon signing, $200,000 within four months of the agreement and $200,000 within nine months of the agreement. The $500,000 is an option to buy a 10% interest in MIFTI for $2,700,000, if completed with 24 months of the agreement date. If the option expires, MIFTI shall issue the Company 500,000 shares of common stock and rescind all other exclusive rights contained in the agreement. The option was rescinded, and the Company received 500,000 shares of MIFTI common stock which represents an ownership of approximately 0.56% for its $500,000 investment. The Company evaluated this investment for impairment and determined that an impairment of $499,000 was necessary during the year ended December 31, 2019. The carrying value of this investment at June 30, 2025 and 2024 was $1,000 and $1,000, respectively.

GRAPHETON

As of June 30, 2025, the Company had three lines of credit with a maximum borrowing amount of $500,000 with interest ranging from 5.5% to 55.0%. As of June 30, 2025, and December 31, 2024, the amounts outstanding under these lines of credit were $409,773 and $309,773, respectively.

Note 8 – Leases

The Company determines whether a contract is or contains a lease at inception of the contract and whether that lease meets the classification criteria of a finance or operating lease. When available, the Company uses the rate implicit in the lease to discount lease payments to present value; however, most of the Company’s leases do not provide a readily determinable implicit rate. Therefore, the Company must discount lease payments based on an estimate of its incremental borrowing rate which is based on the interest rate of similar debt outstanding.

The Company leases its current facilities from Gold Team Inc., a company owned by the Company’s CEO, which owns both the Canoga Park, CA and Milford, Ohio locations. The leases expire annually on April 30, and the Company exercised its renewal option for an additional 12 months. The new lease is not more than 12 months; therefore, the Company has elected the short-term lease exclusion under ASC 842 Leases. On October 1, 2024, Gold Team agreed to forego rent on both properties until July 1, 2025, and no lease expense has been accrued or paid during the six months ending June 30, 2025. Subsequent to June 30, 2025, the rental rate at the Milford, Ohio location was reduced to $6,000 per month, with the first payment due on July 1, 2025. The lease for the Canoga Park, CA location was renewed on a month-to-month basis and GoldTeam has agreed to continue to forgo any rent at the California facility until further notice by GoldTeam. Future minimum lease payments for the remaining six months ending December 31, 2025, is $36,000.

The lease expense for the six months ended June 30, 2025, and 2024 was $0 and $96,000, respectively. Cash paid under operating leases during the six months ended June 30, 2025, and 2024 was $0 and $0, respectively. As of June 30, 2025, the weighted average remaining lease term is 0.75 years, and the weighted average discount rate is 8%.

On September 30, 2024, the cumulative balance payable on the leases was $618,000, of which $300,000 was converted to 300 Series A Convertible Preferred shares of the Company and the remaining balance of $300,000 was converted to a long-term note payable. (see Notes 6 and 13)

All current holders of our Series A preferred have agreed to defer payment of accrued interest and common stock dividends entitled to them until June 30, 2025.

Additional Paid in Capital

During the six months ending June 30, 2025, the Company recorded $394,999 to additional paid in capital in recognition of the fair value of warrants issued for services, a reduction to additional paid in capital of $115 for the cashless exercise of warrants by a noteholder, $24,000 as an incentive expense for the conversion of debt, $8,334 for warrants issued for debt, and $716 for the amortization of employee warrants.

On September 30, 2024, the transaction date for the converted related party debt to Series A Convertible Preferred, the fair market value was estimated using the Option Pricing Model and the fair value of the underlying shares. Since the estimated fair market value was substantially lower than the liability extinguished and the transaction is not considered an arm’s length transaction, the Company recorded the aggregate value of the liability extinguished as a capital contribution.

Warrants

On January 1, 2025, the Company issued two identical cashless warrant agreements for advisory services, entitling each holder to acquire up to 2,500,000 common shares at an exercise price of $0.08 for a three-year term. On the date of issuance, the exercise price was above the fair market value of the underlying shares on the grant date, resulting in no intrinsic value. The fair value at issuance was $394,999. These warrants are equity classified and the fair value at issuance was calculated using the Black Scholes pricing model. No significant unobservable inputs were used in the valuation, and no material adjustments were required. As such, the Company believes the fair value measurement falls within Level 2 of the ASC 820 hierarchy. The specific number of warrants outstanding has not yet been determined but is not expected to exceed the number of shares available for issuance. Should these warrants be fully exercised, common shareholders would experience dilution of up to 5,000,000 common shares.

On April 11, 2025, the Company entered into a two-year Warrant agreement with the operations manager at the Company’s Overhoff division. The Agreement allows the Holder to exercise the warrant, in whole or in part, by cash or cashless exercise. The warrant shares will vest, provided the Holder remains continuously employed by the Company through each applicable vesting date: (1) 25% of the warrant shares will best on the first anniversary of the date of this warrant, and (2) the remaining 75% will vest in equal monthly installments over the following twelve months. If the Holder breaches any fiduciary duty, confidentiality obligation, or other duty of loyalty to the Company at any time following the exercise of this warrant, the Company shall have the right to cancel any warrant shares not yet sold or transferred by the Holder, and /or require the Holder to repay to the Company any and all gains realized from the sale, transfer, or other disposition of warrant shares within a period of one year prior to such breach. Under ASC 718, Stock Compensation, the Company is required to recognize the fair value of these warrants as compensation expense over the vesting period on a straight-line basis. The warrants are equity classified and the fair value at issuance was calculated using the Black Scholes pricing model. No significant unobservable inputs were used in the valuation, and no material adjustments were required. The fair value on the date of grant was $9,800 and the Company recorded $716 as stock compensation expense for the six months ending June 30, 2025.

The Company’s warrants are classified as equity, and their value is carried in the additional paid-in capital account in the stockholders’ equity section of the balance sheet.

On June 6, 2025, the Company issued 1,147,059 common shares to a third party in a cashless exercise of 1,000,000 warrants.

Note 10 – Segment Reporting

ASC Topic 280, “Segment Reporting,” requires use of the “management approach” model for segment reporting. The management approach model is based on the way a company’s management organizes segments within the company for making operating decisions and assessing performance. The Company has two reportable segments: Optron and Overhoff. Optron is located in Canoga Park, California and Overhoff is located in Milford, Ohio. The assets and operations of the Company’s acquisition of the assets of Electronic Control Concepts are included with Overhoff in the table below.

Although the reportable segments use similar production processes for the Company’s hardware and software products and services, each one is managed separately to better align with the type of product manufactured. Our Optron facility produces radiation monitors, while the Overhoff facility manufactures tritium monitors. Both facilities offer calibration and repair services to the respective monitor systems or devices. The Company currently evaluates the performance of its reportable segments based on net sales and operating income. The Company’s Chief Operating Decision Maker (CODM) does not utilize any additional profit/loss metrics or any detailed asset allocations as part of the overall analysis, as the Company does not currently have these specific details available for review. While efforts are being made to enhance our internal metrics and reporting processes, currently, a complete suite of expense metrics for evaluating the effectiveness of our resource allocation across all segments is not fully operational. We are exploring project management tools and centralized platforms to integrate data from various sources and improve visibility into resource utilization. For each reporting segment, the Manager of Operations reports to the CODM, who is the Company’s CEO, Robert Goldstein.

The following tables summarize the Company’s segment information for the three and six months ended June 30, 2025, and 2024:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to help the reader understand US Nuclear Corp, our operations and our present business environment. MD&A is provided as a supplement to—and should be read in conjunction with—our consolidated financial statements and the accompanying notes included in this Quarterly Report on Form 10-Q. The audited financial statements for our fiscal year ended December 31, 2024, filed with the Securities Exchange Commission on Form 10-K on June 25, 2025, should be read in conjunction with the discussion below. This discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results may differ materially from those anticipated in these forward-looking statements. In the opinion of management, all material adjustments necessary to present fairly the results of operations for such periods have been included in these unaudited financial statements.

We were incorporated in Delaware on February 14, 2012, and on March 2, 2012, we filed a registration statement on Form 10 to register with the U.S. Securities and Exchange Commission as a public company. We were originally organized as a vehicle to investigate and, if such investigation warrants, acquire a target company or business seeking the perceived advantages of being a publicly held corporation.

Since our acquisition of Overhoff Technology in 2006, we have had discussions with other companies in our industry for an acquisition. While we targeted Overhoff due to its unique position in the tritium market, we had not commenced an acquisition since our Overhoff Technology acquisition; we believe in part the reason was due to lack of additional capital, our status as a privately held entity at the time, and focus on developing our own products. We will seek out companies whom our management believes will provide value to our customers and will complement our business. We will focus on diversifying our product line into a larger range so that our customers and vendors may have a more expansive experience in type, choice, options, price and selection. We also believe that with a more diverse product line we will become more competitive as our industry is intensely competitive.

Generally, our product concentration places a heavy reliance on our Overhoff Technology division. During the six months ending June 30, 2025, we derived 64% of our total revenues from sales made by Overhoff to two customers. Our international revenues were 8.7% of our total revenue during the six months ended June 30, 2025. We expect this to increase over time as we continue to field new order inquiries and engage new customers overseas. We believe that South Korea and China will likely be a larger contributor to revenue within the next few years. While we maintain steady growth domestically, the international side of our business may be a larger component as nuclear technology and rapid development for clean energy grows abroad. Additionally, the Company relies on continued growth and orders from CANDU reactors (Canada Deuterium Uranium), and rapid development of the next generation of nuclear reactors called Molten Salt Reactors, (MSR) and Liquid-Fluoride Thorium Reactors (LFTR), all of which purchase tritium detection and monitor products. There can be no assurances as to our growth projections and our risk profile as we depend upon increased foreign customers for business.

For the next twelve months, we anticipate we will need approximately $5,000,000 in additional capital to fund our business plans. If we do not raise the required capital, we may not meet our expenses and there can be no assurance that we will be able to do so and if we do, we may find the cost of such financing to be burdensome on the Company. Additionally, we may not be able to execute on our business plans due to unforeseen market forces such as lower natural gas prices, difficulty attracting qualified executive staff, general downturn in our sector or by competition as we operate in an extremely competitive market for all of our product offerings.

Robert I. Goldstein, our President, Chief Executive Officer and Chairman of the Board of Directors also maintains a position as President of Gold Team Inc., a Delaware company that invests in industrial real estate properties for investment purposes. He holds an 8% interest in Gold Team Inc. and spends approximately 5 hours per week on affairs related to Gold Team Inc. The Company leases its current facilities from Gold Team Inc., which owns both the Canoga Park, CA and Milford, Ohio properties at an expense of $9,000 and $9,000, respectively, for each facility per month.

On May 31, 2016, we entered into an Asset Purchase Agreement with Electronic Control Concepts (“ECC”) whereby the Company purchased certain tangible and intangible assets of ECC. ECC is a small manufacturer of test and maintenance meters for x-ray machines both medical and industrial. We acquired ECC to give a boost to our current x-ray related product and hospital/medical product sales.

The increase of $158,415 or 14.1% was principally due to decreases in professional fees and payroll and employee benefits, offset by increases in stock-based compensation.

Liquidity and Capital Resources

Our operations have historically been financed by our majority shareholder and more recently from proceeds from the sale of our common stock. As funds were needed for working capital purposes, our majority shareholder would loan us the needed funds. We anticipate funding the growth of our business through the sales of additional shares of our common stock and loans from our majority stockholder if necessary.

At June 30, 2025, total assets decreased to $2,505,836 from $2,646,847 at December 31, 2024. The decrease primarily reflects decreases in accounts receivable, offset by an increase in inventories.

At June 30, 2025, total liabilities decreased to $3,256,538 from $3,503,012 at December 31, 2024. The decrease is primarily the net of increases in accounts payable and accrued expenses, offset by decreases in deferred revenue, and notes payable. Notes payable and accrued expenses decreased $2,238,000 due to the forgiveness of $360,000 in debt and the conversion of $1,878,000 to Series A convertible preferred stock designated by the Company in 2024.

Net cash used in operating activities for the six months ended June 30, 2025, was $246,113 compared to $189,031 for the same period in 2024. The change in cash used in operations was principally due to changes in inventory, accounts receivable, and customer deposit working capital accounts.

Net cash used in investing activities for the six months ended June 30, 2025, was $0 compared to $18,081 for the same period in 2024. The decrease in cash used in investing activities was due to the decrease of advances and a note receivable.

Net cash provided by financing activities for the six months ended June 30, 2025, was $161,558 compared to $192,121 for the same period in 2024. The decrease in cash from financing activities was primarily due to a reduction of proceeds from shareholder notes payable.

Critical Accounting Policies

Our financial statements and related public financial information are based on the application of accounting principles generally accepted in the United States (“US GAAP”). US GAAP requires the use of estimates; assumptions, judgments and subjective interpretations of accounting principles that have an impact on the assets, liabilities, revenues and expenses amounts reported. These estimates can also affect supplemental information contained in our external disclosures including information regarding contingencies, risk and financial condition. We believe our use of estimates and underlying accounting assumptions adhere to GAAP and are consistently and conservatively applied. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ materially from these estimates under different assumptions or conditions. We continue to monitor significant estimates made during the preparation of our financial statements.

We believe our use of estimates and underlying accounting assumptions adhere to GAAP and are consistently applied. Our significant accounting policies are summarized in Note 2 to our consolidated financial statements.

We have not entered into any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.
