Description of Business and Basis of Presentation [Abstract]
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION	NOTE 1 – DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Nukkleus Inc. and its wholly owned subsidiaries, are financial technology companies focused on providing software, technology solutions, customer sales and marketing, and risk management technology hardware and software solutions packages for the worldwide retail foreign exchange (“FX”) trading industry and payment services from one fiat currency to another or to digital assets. Basis of Presentation and Principles of Consolidation: On the Closing Date, and in connection with the closing of the Business Combination, Brilliant changed its name to Nukkleus Inc (the “Company”) and the Company’s common stock began trading on the NASDAQ under the ticker symbol NUKK. Old Nukk was deemed the accounting acquirer in the Business Combination based on an analysis of the criteria outlined in Accounting Standards Codification (“ASC”) 805, Business Combinations While Brilliant was the legal acquirer in the Business Combination, because Old Nukk was deemed the accounting acquirer, the historical financial statements of Old Nukk became the historical financial statements of the combined company, upon consummation of the Business Combination. As a result, the financial statements included in this report reflect (i) the historical operating results of Old Nukk prior to the Business Combination; (ii) the combined results of Brilliant and Old Nukk following the closing of the Business Combination; (iii) the assets and liabilities of Old Nukk at their historical cost; and (iv) the Company’s equity structure for all periods presented. Effective October 24, 2024, the Company amended its amended and restated certificate of incorporation to implement a one-for-eight reverse stock split of its common stock (the “2024 Reverse Stock Split”) and increased the number of authorized shares of the Company’s common stock from 40,000,000 to 150,000,000 (see Note 14). In accordance with guidance applicable to these circumstances, the equity structure has been restated in all comparative periods to give effect to the number of shares of the Company’s common stock, $0.0001 par value per share, issued to Old Nukk shareholders during the Business Combination and the 2024 Reverse Stock Split. Accordingly, the disclosure of common shares and per common share data in the accompanying consolidated financial statements and related notes reflect the Business Combination and 2024 Reverse Stock Split for all periods presented. The accompanying consolidated financial statements include the accounts of Nukkleus Inc, and its wholly owned subsidiaries. Intercompany transactions and balances have been eliminated upon consolidation. The consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”). Any reference in these footnotes to the applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the ASC and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”).

Liquidity and Capital Resources [Abstract]
LIQUIDITY AND CAPITAL RESOURCES	NOTE 2 – Liquidity and capital resources The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and settlement of liabilities in the normal course of business. On December 22, 2023, the Company consummated the Business Combination and raised net proceeds of $150,161 net of transaction costs and expenses. As of September 30, 2024, the Company had cash of approximately $3,700, exclusive of customer custodial funds. The Company had a working capital deficit of approximately $6,104,000 at September 30, 2024 and incurred a net loss and generated negative cash flow from operating activities of approximately $8,519,000 and $3,818,000, respectively, for the year ended September 30, 2024. These are indicators of substantial doubt as to the Company’s ability to continue as a going concern for at least one year from issuance of these financial statements. The Company’s ability to continue as a going concern is dependent upon the management of expenses and ability to obtain necessary financing to meet its obligations and pay its liabilities arising from normal business operations when they come due, and upon profitable operations. If additional equity or debt financing is required from outside sources, the Company may not be able to raise it on terms acceptable to it or at all. If the Company is unable to raise additional capital on acceptable terms when needed, its results of operations and financial condition would be materially and adversely affected. Any such financing likely would be dilutive to existing stockholders and could result in significant financial operating covenants that would negatively impact the Company business. On December 20, 2024, the Company closed a $10.0 million private placement whereby it received $10.0 million in cash from the sale of shares of the Company’s common stock and stock purchase warrants (see Note 20). Based on the foregoing, management believes that its current financial resources, as of the date of the issuance of these financial statements, are sufficient to fund its current twelve-month operating budget, alleviating any concerns by its historical operating results and satisfying its estimated liquidity needs for the twelve months from the issuance of these financial statements.

Summary of Significant Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 3 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Emerging growth company Use of estimates: Segment reporting: Segment Reporting Cash and cash equivalents: no Country: September 30, September 30, United States $ 199 5.4 % $ 7,675 39.7 % United Kingdom 3,305 89.9 % 11,469 59.4 % Malta 174 4.7 % 174 0.9 % Total cash $ 3,678 100 % $ 19,318 100 % Customer custodial funds and customer custodial cash liabilities: 1 In accordance with regulations in the United Kingdom, and the terms of the principal license holder the Company operates under, the Company is able to extend credit to its customers. At the time the Company’s management designates customer custodial funds held in its United Kingdom bank account to be used to extend credit, the designated amount is re-classified as cash and cash equivalents and no longer classified as customer custodial funds on the Company’s consolidated balance sheets. The remaining assets underlying the customer custodial funds remain separately classified as such on the Company’s consolidated balance sheets. The Company identifies these customer custodial funds separately from corporate funds and maintain them in separate and non-interest bearing accounts. Customer digital currency assets and liabilities: The Company safeguards customer digital currency assets for customers in digital wallets and portions of cryptographic keys necessary to access digital assets on The Company’s platform. The Company safeguards these assets and/or keys and is obligated to safeguard them from loss, theft, or other misuse. The Company records customer digital currency assets and liabilities, in accordance with Staff Accounting Bulletin 121, “ Views of the staff regarding the accounting for obligations to safeguard crypto-assets an entity holds for platform users” 1 References to the Company are to Nukkleus and all of its 100% owned subsidiaries as presented on the financial statements as the disclosures are made at consolidated level and not subsidiary level The Company is committed to securely storing all customer digital assets and cryptographic keys (or portions thereof) held on behalf of customers. The value of these safeguarded assets is recorded as customer digital currency liabilities and corresponding customer digital currency assets. As such, the Company may be liable to its customers for losses arising from theft or loss of private keys. The Company has no reason to believe it will incur any expense associated with such potential liability because (i) it has no known or historical experience of claims to use as a basis of measurement, (ii) it accounts for and continually verifies the amount of digital assets on its platform, and (iii) it has established security around private key management to minimize the risk of theft or loss. The Company has adopted a number of measures to safeguard digital assets it secures including, but not limited to, holding customer digital assets on a 1:1 basis and strategically storing custodied assets offline using the Company’s cold storage process. The Company also does not reuse or rehypothecate customer digital assets nor grant security interests in customer digital assets, in each case unless required by law or expressly agreed to by the institutional customer. Any loss or theft would impact the measurement of the customer digital assets. The Company classifies the customer digital currency assets and liabilities as current based on their purpose and availability to fulfill its direct obligations to its customers. Fair value measurements: Fair Value Measurements ● Level 1 – Inputs based on unadjusted quoted market prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. ● Level 2 – Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar instruments in markets that are not active or for which all significant inputs are observable or can be corroborated by observable market data. ● Level 3 – Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are both unobservable for the asset and liability in the market and significant to the overall fair value measurement. An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. Assets and liabilities measured at fair value are based on one or more of the following techniques noted in ASC 820: ● Market approach: ● Cost approach: ● Income approach: The Company believes its valuation methods are appropriate and consistent with other market participants, however the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The Company’s financial instruments with a carrying value that approximates fair value consist of cash, customer custodial funds, due from affiliates, notes receivable – related parties, net, other current assets, accounts payable, customer custodial cash liabilities, due to affiliates, accrued expenses and other current liabilities, interest payable – related parties, and short-term borrowings due to their liquid or short-term nature or expected settlement dates of these instruments. If these financial instruments were recorded at fair value, they would be based on Level 1 inputs, except for short-term borrowings and notes receivable, related parties, net which would be based on Level 2 and Level 3 inputs, respectively. The Company’s non-financial assets, such as intangible assets, and financial assets are adjusted to fair value when an impairment charge is recognized. The impairment charge recognized on non-financial assets that consist of acquired intangible assets is based on Level 3 inputs, including a comparison of the Company’s results with expectations and expectation for future profits. The impairment charge recognized of non-financial assets that consist of digital assets is based on Level 1 or Level 2 inputs, determined whether there is an active market for the digital asset at period end. The impairment charge recognized for financial assets that consist of investment in privately held equity securities is based on Level 3 inputs, including the global economic environment, adjustments for investment-specific developments and the rights and obligations of the securities the Company holds. The Company’s financial instruments that are measured at fair value on a recurring basis consist of the customer digital currency assets and liabilities (see Note 13). Related parties: Due from affiliates and notes receivable – related parties, net: Other current assets: Allowance for credit losses Customer, Supplier, and Concentration Risk: Cash: Customers: Suppliers: Investments: Investments where the Company (1) holds less than 20% ownership in the entity, and (2) does not exercise significant influence are recorded at cost and adjusted for observable transactions for same or similar investments of the same issuer (referred to as the measurement alternative) or impairment (see Note 7). Investments where the Company (1) holds between 20% and 50% ownership in the entity, and (2) does not control, but over which it does exert significant influence are recorded at cost and adjusted for the company’s share of operating results, capital contributions and distributions (referred to as the equity method). The Company’s equity method investment is associated with the acquisition of 50.0% of the issued and outstanding ordinary shares of a privately held company during March 2022 which is a company developing a custody and settlement utility operating system. The Company has recognized impairment losses on this equity method investment in prior years, which reduced the carrying value of the equity method investment to zero. As of September 30, 2024 and 2023, the total carrying value of investments in privately held companies determined to be VIEs was $0 Intangible assets, net: Impairment of long-lived assets: Impairment or Disposal of Long-Lived Assets The Company assessed its long-lived assets for any impairment and concluded that there were indicators of impairment on the following long-lived assets: ● Investment accounted for under the measurement alternative – Impairment indicators were identified at September 30, 2024 and 2023 as a result of the investee’s continued operating results being significantly lower than forecasts, the global economic environment, and progression on meeting operating milestones. The Company calculated its estimated undiscounted cash flows to be less than the carrying amount related to the cost method investment, recognizing impairment losses of $391,217 and $6,210,783 for the difference for the years ended September 30, 2024 and 2023, respectively. The impairment loss recorded for the year ended September 30, 2024 reduced the carrying value of the cost method investment to $0. ● Acquired identifiable intangible assets – Impairment indicators were identified at September 30, 2023 as a result of the Company’s operating results being significantly lower than forecasts. An impairment loss of $5,695,589 was recorded for the year ended September 30, 2023. The Company did not record any impairment charge for its acquired identifiable intangible assets for the year ended September 30, 2024 as there was no impairment indicator noted. ● Digital assets – Impairment indicators were identified at September 30, 2023 as a result of the carrying value of the digital assets exceeding its fair value at period end. An impairment loss of $7,950 was recorded for the year ended September 30, 2023. The Company did not record any impairment charge for its digital assets for the year ended September 30, 2024 as there was no The assumptions used in the impairment analyses represent Level 3 inputs. Note payable, loans payable – related parties, convertible notes payable: The Company evaluates convertible notes payable in accordance with ASC 470, “ Debt with Conversion and Other Options Gains and losses on extinguishment of liabilities: The Company classifies the gains and losses on extinguishment of liabilities with related partiesthe gain or loss on the extinguishment of each obligation with a related party as a reduction of capital in the accompanying statements of changes in stockholders’ deficit or as a component of other expense (income), net in the accompanying consolidated statements of operations and comprehensive loss based on the facts and circumstances of each extinguishment transaction. Stock purchase warrants: Distinguishing liabilities from equity Derivatives and Hedging 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 at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the liability classified warrants are recognized as a non-cash gain or loss on the accompanying consolidated statements of operations and comprehensive loss. The Company assesses the classification of its common stock purchase warrants at each reporting date to determine whether a change in classification between equity and liability is required. Revenue recognition: ● Identify the contract, or contracts, with the customer ● Identify the performance obligations in the contract ● Determine the transaction price ● Allocate the transaction price to the performance obligations in the contract ● Recognize revenue when the company satisfies a performance obligation Revenue is recognized when control of the promised goods or services is transferred to the customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. General support services: Judgment is required in determining whether the Company is the principal or the agent in the provision of general support services as the Company utilizes a third party to perform the general support services. The Company evaluates the presentation of revenue on a gross or net basis based on whether it is responsible for fulfilling the promise (gross) or whether the third party performing the services is responsible for fulling the promise to the Company’s customer (net). The Company is contractually obligated to provide the fulfillment software, technology, customer sales and marketing and risk management technology hardware and software solutions package to the customer and through a shareholder’s ownership of the third party contracted to perform the general support services, controls the services of its service provider necessary to legally transfer of the services to the customer. The Company sets the price of the general support services through an executed contract with the customer. As a result, the Company acts as the principal by providing the ongoing service support that enables its customers to conduct its business without interruption. The Company considers its performance obligation satisfied and recognizes revenue over time as the general support services are rendered. The Company recognizes the full contracted amount each period with no deferred revenue. The Company recognizes revenue equal to the rate specified in the contract with the customer over the term specified in the contract. Financial services: Judgment is required in determining whether the Company is the principal or the agent in financial services transactions. The Company evaluates the presentation of revenue on a gross or net basis based on whether it controls the asset provided before it is transferred to the customer or the customer’s beneficiary (gross) or whether it acts as an agent by arranging for other parties to provide the asset to the customer (net). The Company does not control the fiat currency or digital asset being provided before it is transferred to the customer or customer’s beneficiary, does not have inventory risk related to the fiat currency or digital asset, and is not responsible for the fulfillment of the fiat currency or digital asset. The Company also does not set the price for the fiat currency or digital asset as the price is a market rate established by users of the platform. As a result, the Company acts as an agent in facilitating the ability for a customer to transfer fiat currency or digital assets to itself or its beneficiary. The Company considers its performance obligation satisfied at a point in time and recognizes revenue at the point in time the transaction completes. Contracts with customers are usually open-ended and can be terminated by either party without a termination penalty. Therefore, contracts are defined at the transaction level and do not extend beyond the service already provided. The Company charges a fee at the transaction level. The transaction price, represented by the transaction fee, is calculated based on volume and varies depending on payment type and the value of the transaction. The transaction fee is collected from the customer at the time the transaction is executed. In certain instances, the transaction fee can be collected in digital assets, with revenue measured based on the amount of digital assets received and the fair value of the digital asset at the time of the transaction. Prepayments, if any, received from customers prior to the services being performed are recorded as advances from customers. In these cases, when the services are performed, the appropriate portion of the amount recorded as advance from customers is recognized as revenue. There were no The Company has elected to apply the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that would otherwise have been recognized is one year or less. The following table summarizes revenues disaggregated by geography, based on domicile of the customers, as applicable: Years Ended September 30, 2024 2023 Malta $ 4,800,000 $ 19,200,000 Rest of the world 1 1,113,461 2,097,642 5,913,461 21,297,642 1 No other individual country accounted for more than 10% of total revenue. Advertising: Stock-based compensation: The Company has elected to account for forfeitures of awards as they occur, with previously recognized compensation reversed in the period that the awards are forfeited. Income taxes: The Company is required to evaluate the tax positions taken in the course of preparing its tax returns to determine whether tax positions are more likely than not of being sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the “more-likely-than-not” threshold would be recorded as a tax expense in the current year. The amount recognized is subject to estimate and management judgment with respect to the likely outcome of each uncertain tax position. The amount that is ultimately sustained for an individual uncertain tax position or for all uncertain tax positions in the aggregate could differ from the amount that is initially recognized. The Company recognizes interest and penalties related to income tax matters in general and administrative expense. For U.S. federal tax purposes, digital asset transactions are treated on the same tax principles as property transactions. The Company recognizes a gain or loss when digital assets are exchanged for other property, in the amount of the difference between the fair market value of the property received and the tax basis of the exchanged digital assets. Receipts of digital assets in exchange for goods or services are included in taxable income at the fair market value on the date of receipt. Foreign currency translation: Remeasurement gains and losses from transactions that are not denominated in the functional currency are recorded as a component of other income in the consolidated statements of operations and comprehensive loss. Most of the Company’s revenue transactions are transacted in the functional currency of the Company. The Company does not enter into any material transaction in foreign currencies. Transaction gains or losses have not had, and are not expected to have, a material effect on the results of operations of the Company. Comprehensive loss: Net loss per share: outstanding during the period, excluding the effects of any potential dilutive securities. Diluted earnings per share is computed similar to basic earnings per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common share equivalents had been issued and if the additional common shares were dilutive. Earnings per share excludes all potential dilutive shares of common shares if their effect is anti-dilutive For the years ended September 30, 2024 and 2023, potentially dilutive common shares consist of the common shares issuable upon the exercise of common stock options and warrants (using the treasury stock method) and the conversion of convertible notes payable. In a period in which the Company has a net loss, all potentially dilutive securities are excluded from the computation of diluted shares outstanding as they would have had an anti-dilutive impact. The following table summarizes the potentially dilutive securities excluded from the computation of diluted shares outstanding because the effect of including these potential shares was anti-dilutive: Years Ended September 30, 2024 2023 Options to purchase common stock under Old Nukk equity incentive plan 15,538 15,538 Convertible notes payable that convert into common stock 467,400 - Stock purchase warrants to acquire common stock 1,177,160 837,625 Total potentially dilutive securities 1,660,098 853,163 Reclassification: Recently issued accounting pronouncements, adopted Effective October 1, 2023, the Company adopted the requirements of ASU 2016-13, Financial Instruments - Credit Losses (“Topic 326”) In August 2020, ASU 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40) Recently issued accounting pronouncements, not yet adopted ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative ASU 2023-07, Segment Reporting – Improvements to Reportable Segment Disclosures ASU 2023-08, Accounting for and Disclosure of Crypto Assets ASU 2023-09, Income Taxes ASU 2024-02, Codification Improvements-Amendments to Remove References to the Concepts Statements ASU 2024-03, Disaggregation of Income Statement Expenses

Reverse Recapitalization [Abstract]
REVERSE RECAPITALIZATION	NOTE 4 – REVERSE RECAPITALIZATION On December 22, 2023, Old Nukk and Brilliant consummated the merger contemplated by the Business Combination with Old Nukk surviving the merger as a wholly-owned subsidiary of Brilliant. Upon the closing of the Business Combination, Brilliant’s certificate of incorporation was amended and restated to, among other things, set the total number of authorized shares of capital to 55,000,000 shares, of which 40,000,000 shares were designated common stock, $0.0001 par value per share, and of which 15,000,000 shares were designated preferred stock, $0.0001 par value per share. Upon the consummation of the Business Combination, each share of Old Nukk common stock issued and outstanding was cancelled and converted into the right to receive a pro-rata portion of 1,312,494 shares of the Company’s common stock. Outstanding stock options, whether vested or unvested, to purchase shares of Old Nukk common stock (see Note 15) converted into stock options for shares of the Company’s common stock (each, an “Assumed Option”), upon the same terms and conditions that were in effect with respect to such stock options immediately prior to the Business Combination, after giving effect to an exchange ratio applicable to the Old Nukk outstanding stock options of 1:35. Outstanding Public Warrants and Private Warrants (see Note 14) to purchase shares of Brilliant Ordinary Shares remained outstanding at the Closing Date. The warrants became exercisable 30 days after the completion of the Business Combination and will expire five years after the completion of the Business Combination or earlier upon redemption or liquidation. Subsequent to the Business Combination, there were 837,625 Company warrants outstanding. A backstop pool was determined to be 26,668, 40% of the aggregate number of Brilliant Ordinary shares and Brilliant Rights, in accordance with the terms of the merger agreements (the “Backstop Pool”) and was issued to certain holders of Brilliant Ordinary Shares, Brilliant Rights, and Brilliant Warrants as follows: ● Certain Brilliant shareholders received an additional issuance of shares or warrants as follows: o Holders of Brilliant Ordinary Shares received shares of the Company’s common stock equal to their pro rata share of the Backstop Pool o Holders of Brilliant Rights received shares of the Company’s common stock equal to their pro-rata share of the Backstop Pool o Holders of Brilliant Warrants, other than warrants held by Brilliant’s sponsor or affiliates, received additional Company Warrants that will be exercisable to receive a share of the Company’s common stock plus an additional number of Company warrants equal to their pro rata share of the aggregate number of Brilliant Ordinary Shares and Brilliant Rights outstanding. In connection with the Business Combination, certain Brilliant shareholders exercised their right to redeem certain of their outstanding shares for cash, resulting in the redemption of 41,305 shares of Brilliant Class A Ordinary Shares at approximately $92.56 per share, for gross redemption payments of $3,822,431. Additionally, a balance owed to the sponsor of Brilliant totaling $3,881,627 was settled through the issuance of 12,935 shares of the Company’s common stock. The Business Combination is accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Brilliant was treated as the “acquired” company for financial reporting purposes. See Note 1 “Description of business and basis of presentation” for further details. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Old Nukk issuing stock for the net assets of Brilliant, accompanied by a recapitalization. The net assets of Brilliant are stated as historical cost, with no goodwill or intangible assets recorded. Prior to the Business Combination, Old Nukk and Brilliant filed separate standalone federal, state and local income tax returns. As a result of the Business Combination, Old Nukk will file a consolidated income tax return. Although, for legal purposes, Brilliant acquired Old Nukk, and the transaction represents a reverse acquisition for federal income tax purposes. Brilliant will be the parent of the consolidated group, with Old Nukk a subsidiary, but in the year of the closing of the Business Combination, Old Nukk will file a full year tax return with Brilliant joining in the return the day after the Closing Date.

The valuation allowance could be reduced or eliminated based on future earnings and future estimates of taxable income. At each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. On the basis of this evaluation, only the portion of the deferred tax asset that is more likely than not to be realized was recognized. However, if the Company is not able to generate sufficient taxable income from its operations in the future, then a valuation allowance to reduce the Company’s U.S. deferred tax assets may be required, which would increase the Company’s expenses in the period the allowance is recognized. As of September 30, 2024, the Company had $8,439,349 in U.S. federal net operating loss carry-forwards that can be utilized in future periods to reduce taxable income. However, due to changes in stock ownership, the use of the U.S. federal net operating loss carry-forwards is limited under Section 382 of the Internal Revenue Code. The Company has not performed a study to determine if the loss carryforwards are subject to these Section 382 limitations. $258,405 of the net operating loss carry-forwards will expire in fiscal years 2033 through 2038. The remaining net operating loss carry-forwards do not expire. In addition, the Company has net operating losses in Malta and United Kingdom totaling $447,770 and $1,890,545, respectively, with no expiration date. As of September 30, 2024 and 2023, the Company did not identify any uncertain tax positions that would require either recognition or disclosure in the accompanying consolidated financial statements. The Company recognizes interest and penalties related to uncertain income tax positions in income tax expense. There was no interest or penalties recorded for the years ended September 30, 2024 and 2023. The Company has a December 31 tax year-end. The federal, state and foreign income tax returns of the Company are subject to examination by various tax authorities, generally for three years after they are filed.

It is not possible to determine the maximum potential exposure under these indemnification agreements: (i) because the facts and circumstances involved in each claim are unique and the Company cannot predict the number or nature of claims that may be made; (ii) due to the unique facts and circumstances involved in each particular agreement; and (iii) due to the requirement for a registration of the Company’s securities before any of the indemnification obligations contemplated in the IRA become effective. Legal and regulatory proceedings: There is a deficit between customer assets and liabilities as of September 30, 2024 and September 30, 2023. We are subject to regulatory and legal review in the jurisdictions we operate in. There are currently no claims against the Company. Any claims or regulatory actions against us, whether meritorious or not, could be time consuming, result in costly litigation, settlement payments, damage awards (including statutory damages for certain causes of action in certain jurisdictions), fines, penalties, injunctive relief, or increased costs of doing business through adverse judgment or settlement, require us to change our products, services or business practices in expensive ways, require significant amounts of management time, result in the diversion of significant operations resources, or otherwise harm our business. Tax regulation: Current promulgated tax rules related to digital assets are unclear and require significant judgments to be made in interpretation of the law, including but not limited to the areas of income tax, information reporting, transaction level taxes and the withholding of tax at source.

Customer custodial funds and customer custodial cash liabilities	Customer custodial funds and customer custodial cash liabilities: 1 In accordance with regulations in the United Kingdom, and the terms of the principal license holder the Company operates under, the Company is able to extend credit to its customers. At the time the Company’s management designates customer custodial funds held in its United Kingdom bank account to be used to extend credit, the designated amount is re-classified as cash and cash equivalents and no longer classified as customer custodial funds on the Company’s consolidated balance sheets. The remaining assets underlying the customer custodial funds remain separately classified as such on the Company’s consolidated balance sheets. The Company identifies these customer custodial funds separately from corporate funds and maintain them in separate and non-interest bearing accounts.
Customer digital currency assets and liabilities	Customer digital currency assets and liabilities: The Company safeguards customer digital currency assets for customers in digital wallets and portions of cryptographic keys necessary to access digital assets on The Company’s platform. The Company safeguards these assets and/or keys and is obligated to safeguard them from loss, theft, or other misuse. The Company records customer digital currency assets and liabilities, in accordance with Staff Accounting Bulletin 121, “ Views of the staff regarding the accounting for obligations to safeguard crypto-assets an entity holds for platform users” 1 References to the Company are to Nukkleus and all of its 100% owned subsidiaries as presented on the financial statements as the disclosures are made at consolidated level and not subsidiary level The Company is committed to securely storing all customer digital assets and cryptographic keys (or portions thereof) held on behalf of customers. The value of these safeguarded assets is recorded as customer digital currency liabilities and corresponding customer digital currency assets. As such, the Company may be liable to its customers for losses arising from theft or loss of private keys. The Company has no reason to believe it will incur any expense associated with such potential liability because (i) it has no known or historical experience of claims to use as a basis of measurement, (ii) it accounts for and continually verifies the amount of digital assets on its platform, and (iii) it has established security around private key management to minimize the risk of theft or loss. The Company has adopted a number of measures to safeguard digital assets it secures including, but not limited to, holding customer digital assets on a 1:1 basis and strategically storing custodied assets offline using the Company’s cold storage process. The Company also does not reuse or rehypothecate customer digital assets nor grant security interests in customer digital assets, in each case unless required by law or expressly agreed to by the institutional customer. Any loss or theft would impact the measurement of the customer digital assets. The Company classifies the customer digital currency assets and liabilities as current based on their purpose and availability to fulfill its direct obligations to its customers.
Fair value measurements	Fair value measurements: Fair Value Measurements ● Level 1 – Inputs based on unadjusted quoted market prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. ● Level 2 – Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar instruments in markets that are not active or for which all significant inputs are observable or can be corroborated by observable market data. ● Level 3 – Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are both unobservable for the asset and liability in the market and significant to the overall fair value measurement. An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. Assets and liabilities measured at fair value are based on one or more of the following techniques noted in ASC 820: ● Market approach: ● Cost approach: ● Income approach: The Company believes its valuation methods are appropriate and consistent with other market participants, however the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The Company’s financial instruments with a carrying value that approximates fair value consist of cash, customer custodial funds, due from affiliates, notes receivable – related parties, net, other current assets, accounts payable, customer custodial cash liabilities, due to affiliates, accrued expenses and other current liabilities, interest payable – related parties, and short-term borrowings due to their liquid or short-term nature or expected settlement dates of these instruments. If these financial instruments were recorded at fair value, they would be based on Level 1 inputs, except for short-term borrowings and notes receivable, related parties, net which would be based on Level 2 and Level 3 inputs, respectively. The Company’s non-financial assets, such as intangible assets, and financial assets are adjusted to fair value when an impairment charge is recognized. The impairment charge recognized on non-financial assets that consist of acquired intangible assets is based on Level 3 inputs, including a comparison of the Company’s results with expectations and expectation for future profits. The impairment charge recognized of non-financial assets that consist of digital assets is based on Level 1 or Level 2 inputs, determined whether there is an active market for the digital asset at period end. The impairment charge recognized for financial assets that consist of investment in privately held equity securities is based on Level 3 inputs, including the global economic environment, adjustments for investment-specific developments and the rights and obligations of the securities the Company holds. The Company’s financial instruments that are measured at fair value on a recurring basis consist of the customer digital currency assets and liabilities (see Note 13).

Investments	Investments: Investments where the Company (1) holds less than 20% ownership in the entity, and (2) does not exercise significant influence are recorded at cost and adjusted for observable transactions for same or similar investments of the same issuer (referred to as the measurement alternative) or impairment (see Note 7). Investments where the Company (1) holds between 20% and 50% ownership in the entity, and (2) does not control, but over which it does exert significant influence are recorded at cost and adjusted for the company’s share of operating results, capital contributions and distributions (referred to as the equity method). The Company’s equity method investment is associated with the acquisition of 50.0% of the issued and outstanding ordinary shares of a privately held company during March 2022 which is a company developing a custody and settlement utility operating system. The Company has recognized impairment losses on this equity method investment in prior years, which reduced the carrying value of the equity method investment to zero. As of September 30, 2024 and 2023, the total carrying value of investments in privately held companies determined to be VIEs was $0

Impairment of long-lived assets	Impairment of long-lived assets: Impairment or Disposal of Long-Lived Assets The Company assessed its long-lived assets for any impairment and concluded that there were indicators of impairment on the following long-lived assets: ● Investment accounted for under the measurement alternative – Impairment indicators were identified at September 30, 2024 and 2023 as a result of the investee’s continued operating results being significantly lower than forecasts, the global economic environment, and progression on meeting operating milestones. The Company calculated its estimated undiscounted cash flows to be less than the carrying amount related to the cost method investment, recognizing impairment losses of $391,217 and $6,210,783 for the difference for the years ended September 30, 2024 and 2023, respectively. The impairment loss recorded for the year ended September 30, 2024 reduced the carrying value of the cost method investment to $0. ● Acquired identifiable intangible assets – Impairment indicators were identified at September 30, 2023 as a result of the Company’s operating results being significantly lower than forecasts. An impairment loss of $5,695,589 was recorded for the year ended September 30, 2023. The Company did not record any impairment charge for its acquired identifiable intangible assets for the year ended September 30, 2024 as there was no impairment indicator noted. ● Digital assets – Impairment indicators were identified at September 30, 2023 as a result of the carrying value of the digital assets exceeding its fair value at period end. An impairment loss of $7,950 was recorded for the year ended September 30, 2023. The Company did not record any impairment charge for its digital assets for the year ended September 30, 2024 as there was no The assumptions used in the impairment analyses represent Level 3 inputs.
Note payable, loans payable – related parties, convertible notes payable	Note payable, loans payable – related parties, convertible notes payable: The Company evaluates convertible notes payable in accordance with ASC 470, “ Debt with Conversion and Other Options
Gains and losses on extinguishment of liabilities	Gains and losses on extinguishment of liabilities: The Company classifies the gains and losses on extinguishment of liabilities with related partiesthe gain or loss on the extinguishment of each obligation with a related party as a reduction of capital in the accompanying statements of changes in stockholders’ deficit or as a component of other expense (income), net in the accompanying consolidated statements of operations and comprehensive loss based on the facts and circumstances of each extinguishment transaction.
Stock purchase warrants	Stock purchase warrants: Distinguishing liabilities from equity Derivatives and Hedging 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 at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the liability classified warrants are recognized as a non-cash gain or loss on the accompanying consolidated statements of operations and comprehensive loss. The Company assesses the classification of its common stock purchase warrants at each reporting date to determine whether a change in classification between equity and liability is required.
Revenue recognition	Revenue recognition: ● Identify the contract, or contracts, with the customer ● Identify the performance obligations in the contract ● Determine the transaction price ● Allocate the transaction price to the performance obligations in the contract ● Recognize revenue when the company satisfies a performance obligation Revenue is recognized when control of the promised goods or services is transferred to the customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. General support services: Judgment is required in determining whether the Company is the principal or the agent in the provision of general support services as the Company utilizes a third party to perform the general support services. The Company evaluates the presentation of revenue on a gross or net basis based on whether it is responsible for fulfilling the promise (gross) or whether the third party performing the services is responsible for fulling the promise to the Company’s customer (net). The Company is contractually obligated to provide the fulfillment software, technology, customer sales and marketing and risk management technology hardware and software solutions package to the customer and through a shareholder’s ownership of the third party contracted to perform the general support services, controls the services of its service provider necessary to legally transfer of the services to the customer. The Company sets the price of the general support services through an executed contract with the customer. As a result, the Company acts as the principal by providing the ongoing service support that enables its customers to conduct its business without interruption. The Company considers its performance obligation satisfied and recognizes revenue over time as the general support services are rendered. The Company recognizes the full contracted amount each period with no deferred revenue. The Company recognizes revenue equal to the rate specified in the contract with the customer over the term specified in the contract. Financial services: Judgment is required in determining whether the Company is the principal or the agent in financial services transactions. The Company evaluates the presentation of revenue on a gross or net basis based on whether it controls the asset provided before it is transferred to the customer or the customer’s beneficiary (gross) or whether it acts as an agent by arranging for other parties to provide the asset to the customer (net). The Company does not control the fiat currency or digital asset being provided before it is transferred to the customer or customer’s beneficiary, does not have inventory risk related to the fiat currency or digital asset, and is not responsible for the fulfillment of the fiat currency or digital asset. The Company also does not set the price for the fiat currency or digital asset as the price is a market rate established by users of the platform. As a result, the Company acts as an agent in facilitating the ability for a customer to transfer fiat currency or digital assets to itself or its beneficiary. The Company considers its performance obligation satisfied at a point in time and recognizes revenue at the point in time the transaction completes. Contracts with customers are usually open-ended and can be terminated by either party without a termination penalty. Therefore, contracts are defined at the transaction level and do not extend beyond the service already provided. The Company charges a fee at the transaction level. The transaction price, represented by the transaction fee, is calculated based on volume and varies depending on payment type and the value of the transaction. The transaction fee is collected from the customer at the time the transaction is executed. In certain instances, the transaction fee can be collected in digital assets, with revenue measured based on the amount of digital assets received and the fair value of the digital asset at the time of the transaction. Prepayments, if any, received from customers prior to the services being performed are recorded as advances from customers. In these cases, when the services are performed, the appropriate portion of the amount recorded as advance from customers is recognized as revenue. There were no The Company has elected to apply the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that would otherwise have been recognized is one year or less. The following table summarizes revenues disaggregated by geography, based on domicile of the customers, as applicable: Years Ended September 30, 2024 2023 Malta $ 4,800,000 $ 19,200,000 Rest of the world 1 1,113,461 2,097,642 5,913,461 21,297,642 1 No other individual country accounted for more than 10% of total revenue.

Stock-based compensation	Stock-based compensation: The Company has elected to account for forfeitures of awards as they occur, with previously recognized compensation reversed in the period that the awards are forfeited.
Income taxes	Income taxes: The Company is required to evaluate the tax positions taken in the course of preparing its tax returns to determine whether tax positions are more likely than not of being sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the “more-likely-than-not” threshold would be recorded as a tax expense in the current year. The amount recognized is subject to estimate and management judgment with respect to the likely outcome of each uncertain tax position. The amount that is ultimately sustained for an individual uncertain tax position or for all uncertain tax positions in the aggregate could differ from the amount that is initially recognized. The Company recognizes interest and penalties related to income tax matters in general and administrative expense. For U.S. federal tax purposes, digital asset transactions are treated on the same tax principles as property transactions. The Company recognizes a gain or loss when digital assets are exchanged for other property, in the amount of the difference between the fair market value of the property received and the tax basis of the exchanged digital assets. Receipts of digital assets in exchange for goods or services are included in taxable income at the fair market value on the date of receipt.
Foreign currency translation	Foreign currency translation: Remeasurement gains and losses from transactions that are not denominated in the functional currency are recorded as a component of other income in the consolidated statements of operations and comprehensive loss. Most of the Company’s revenue transactions are transacted in the functional currency of the Company. The Company does not enter into any material transaction in foreign currencies. Transaction gains or losses have not had, and are not expected to have, a material effect on the results of operations of the Company.
Comprehensive loss	Comprehensive loss:
Net loss per share	Net loss per share: outstanding during the period, excluding the effects of any potential dilutive securities. Diluted earnings per share is computed similar to basic earnings per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common share equivalents had been issued and if the additional common shares were dilutive. Earnings per share excludes all potential dilutive shares of common shares if their effect is anti-dilutive For the years ended September 30, 2024 and 2023, potentially dilutive common shares consist of the common shares issuable upon the exercise of common stock options and warrants (using the treasury stock method) and the conversion of convertible notes payable. In a period in which the Company has a net loss, all potentially dilutive securities are excluded from the computation of diluted shares outstanding as they would have had an anti-dilutive impact.
