Organization
Organization	1. Organization Description of Business ASP Isotopes Inc. was incorporated in the state of Delaware on September 13, 2021, and has its principal operations in Washington, DC. ASP Isotopes Inc.’s subsidiary ASP Isotopes Guernsey Limited (“ASP Guernsey”), has its principal operations in Guernsey. ASP Guernsey’s subsidiary, ASP Isotopes South Africa Proprietary Limited (“ASP South Africa”), has its principal operations in South Africa. ASP Rentals Proprietary Limited (“ASP Rentals”), a variable interest entity (“VIE”) of ASP South Africa, has its principal operations in South Africa. Enlightened Isotopes (Pty) Ltd (“Enlightened Isotopes”), a 80 % owned subsidiary of ASP South Africa, was formed in March 2023 and began operations in January 2024. ASP Isotopes UK Ltd (“ASP UK”), a subsidiary of ASP Guernsey, was incorporated in July 2022. ASPI South Africa Asset Finance Proprietary Limited ("ASP SA Asset Finance”), a subsidiary of ASP South Africa, was incorporated in July 2024. PET Labs Global Nuclear Medicine SEZC (“PET Labs Global”), a subsidiary of ASP Guernsey, was incorporated in June 2024 in the Cayman Islands. PET Labs Pharmaceuticals Proprietary Limited (“PET Labs”), a 51 % owned subsidiary of ASP Isotopes Inc. operates in South Africa. ASP Isotopes Inc.’s subsidiary, Quantum Leap Energy LLC, was formed in the state of Delaware in September 2023 and began operations in February 2024. Quantum Leap Energy LLC’s subsidiary Quantum Leap Energy Proprietary Limited (“Quantum Leap Energy South Africa”), has its operations in South Africa. ASP Isotopes Inc., its subsidiaries and ASP Rentals are collectively referred to as “the Company” throughout these consolidated statements. The Company is a development stage advanced materials company dedicated to the development of technology and processes that, if successful, will allow for the enrichment of natural isotopes into higher concentration products, which could be used in several industries. The Company’s proprietary technology, the Aerodynamic Separation Process (“ASP technology”), originally developed by Klydon Proprietary Ltd (“Klydon”), is designed to enable the production of isotopes used in several industries. The Company’s initial focus is on the production and commercialization of enriched Carbon-14 (“C-14”), Molybdenum-100 (“Mo-100”) and Silicon-28 (“Si-28”). The Company has completed an isotope enrichment plant for the enrichment of C-14 located in Pretoria, South Africa and we expect to start commercial supply of C-14 in the first quarter of 2025, assuming timely delivery of the feedstock from the Company's customer. The Company anticipates completion and commissioning of a multi-isotope enrichment plant in Pretoria, South Africa in the fourth quarter 2024, and the Company expects to start initial commercial supply of Si-28 in early 2025. In addition, the Company has started planning additional isotope enrichment plants. The Company believes the C-14 it may develop using the ASP technology may be used in the development of new pharmaceuticals and agrochemicals. The Company believes that the Mo-100 it may develop using the ASP technology has significant potential advantages for use in the preparation of nuclear imaging agents by radiopharmacies and others in the medical industry. The Company believes the Si-28 it may develop using the ASP technology may be used to develop advanced semiconductors and in quantum computing. In addition, the Company is considering the future development of the ASP technology for the separation of Zinc-68, Xenon-129/136 for potential use in the healthcare end market, Germanium 70/72/74 for possible use in the semiconductor end market, and Chlorine-37 for potential use in the nuclear energy end market. The Company is also developing quantum enrichment technology to produce enriched Ytterbium-176 (“Yb-176”), Nickel-64, Lithium6, Lithium-7 and Uranium-235 (“U-235”). Quantum enrichment is an advanced isotope enrichment technique that is currently in development that uses lasers. The Company believes the U-235 that it may develop using quantum enrichment technology may be commercialized as a nuclear fuel component for use in the new generation of high-assay low-enriched uranium (HALEU)-fueled small modular reactors that are now under development for commercial and government uses. The construction of the Company's first quantum enrichment facility was completed in August 2024, and the Company produced the first semi-finished material of enriched Yb-176 during the commissioning phase of the plant in October 2024. The Company expects to be able to achieve a 99.75 % enrichment for Yb-176 and offer highly enriched Yb-176 for commercial sale during 2025. The Company also expects to proceed with the plans to construct Nickel-64 and Lithium- 6/7 quantum enrichment plants with targeted production during 2025. Liquidity The Company has experienced net losses and negative cash flows from operating activities since its inception. The Company incurred net losses of $ 23,201,675 and $ 12,123,907 for the nine months ended September 30, 2024 and 2023, respectively. The Company currently expects that its cash and cash equivalents of $ 51,571,540 as of September 30, 2024 will be sufficient to fund its operating expenses and capital requirements for more than 12 months from the date the financial statements are issued. In November 2024, the Company issued an additional 2,754,250 shares of common stock in a public offering at a public offering price of $ 6.75 per share for net proceeds of approximately $ 17,100,000 . The Company anticipates it will need to continue to raise capital through additional equity and/or debt financings and/or collaborative development agreements to fund its operations. There can be no assurance that the Company will achieve or sustain positive cash flows from operations or profitability. The Company is in the process of seeking additional debt and equity financing. However, such funding may not be available on a timely basis on terms acceptable to the Company, or at all. If the Company is unable to raise additional capital when required or on acceptable terms, the Company may be required to scale back or discontinue the advancement of product candidates, reduce headcount, reorganize, merge with another entity, or cease operations.

Basis of Presentation and Summary of Significant Accounting Policies
Basis of Presentation and Summary of Significant Accounting Policies	2. Basis of Presentation and Summary of Significant Accounting Policies Unaudited Financial Information The Company’s unaudited condensed consolidated financial statements included herein have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP"), and pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. In the Company’s opinion, the information furnished reflects all adjustments, all of which are of a normal and recurring nature, necessary for a fair presentation of the financial position and results of operations for the reported interim periods. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year or any other interim period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes for the year ended December 31, 2023 . Basis of Presentation and Use of Estimates The Company’s condensed consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of the Company’s condensed consolidated financial statements requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities and expenses and disclosure in the Company’s condensed consolidated financial statements and accompanying notes. The most significant estimates in the Company’s consolidated financial statements relate to stock-based compensation expense, the accounting for the acquisition of PET Labs and fair value measurement of the convertible notes payable and warrants. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results may materially differ from these estimates and assumptions. Principles of consolidation The Company’s condensed consolidated financial statements include the accounts of ASP Isotopes Inc., its wholly-owned subsidiaries, the 80 % owned Enlightened Isotopes, the 51 % owned PET Labs and the 42 % owned VIE ASP Rentals. All intercompany balances and transactions have been eliminated in consolidation. Currency and currency translation The condensed consolidated financial statements are presented in U.S. dollars, the Company’s reporting currency. The functional currency of ASP Isotopes Inc. and ASP Guernsey is the U.S. dollar. The functional currency of the Company’s subsidiaries ASP South Africa and Quantum Leap Energy South Africa is the South African Rand. The functional currency of the 80 % owned Enlighted Isotopes, the 51 % owned PET Labs and the 42 % owned VIE ASP Rentals is the South African Rand. Adjustments that arise from exchange rate changes on transactions of each group entity denominated in a currency other than the functional currency are included in other income and expense in the consolidated statements of operations and comprehensive loss. Assets and liabilities of the entities with functional currency of South African Rand are recorded in South African Rand and translated into the U.S. dollar reporting currency of the Company at the exchange rate on the balance sheet date. Revenue and expenses of the entities with functional currency of South African Rand are recorded in South African Rand and translated into the U.S. dollar reporting currency of the Company at the average exchange rate prevailing during the reporting period. Resulting translation adjustments are recorded separately in stockholders’ equity as a component of accumulated other comprehensive (loss) income. Concentration of Credit Risk and other Risks Cash balances maintained at U.S. financial institutions may exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance limit of $ 250,000 per depositor, per insured bank for each account ownership category. Although the Company currently believes that the financial institutions with whom it does business, will be able to fulfill their commitments to the Company, there is no assurance that those institutions will be able to continue to do so. The Company has not experienced any credit losses associated with its balances in such accounts for the nine months ended September 30, 2024 and 2023. The Company's foreign subsidiaries held cash of approximately $ 2,062,000 and $ 1,963,000 as of September 30, 2024 and December 31, 2023 , respectively, which is included in cash on the consolidated balance sheets. The Company's strategic plan does not require the repatriation of foreign cash in order to fund its operations in the U.S., and it is the Company's current intention to indefinitely reinvest its foreign cash outside of the U.S. If the Company were to repatriate foreign cash to the U.S., the Company would be required to accrue and pay U.S. taxes in accordance with applicable U.S. tax rules and regulations as a result of the repatriation. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities at the date of purchase of three months or less to be cash equivalents. Cash and cash equivalents are stated at fair value and may include money market funds, U.S. Treasury and U.S. government-sponsored agency securities, corporate debt, commercial paper and certificates of deposit. The Company had cash equivalents of $ 186,229 in the form of money market funds as of September 30, 2024 . The Company had no cash equivalents as of December 31, 2023 . Segment Information As of December 31, 2023 , the Company managed its operations as a single segment, specialist isotopes and related services. Beginning in 2024, primarily as a result of increased business activities of its subsidiary, Quantum Leap Energy LLC, the Company has two operating segments: (i) nuclear fuels, and (ii) specialist isotopes and related services. The nuclear fuels segment is focused on research and development of technologies and methods used to produce high-assay low-enriched uranium (HALEU) and Lithium-6 for the advanced nuclear fuels target end market. The specialist isotopes and related services segment is focused on research and development of technologies and methods used to separate high-value, low-volume isotopes (such as C-14, Mo-100 and Si-28) for highly specialized target end markets other than advanced nuclear fuels, including pharmaceuticals and agrochemicals, nuclear medical imaging and semiconductors, as well as services related to these isotopes, and this segment includes PET Labs. The financial information is regularly reviewed by the chief operating decision maker (“CODM”) in deciding how to allocate resources. The Company’s CODM is its chief executive officer. The Company manages assets on a total company basis, not by operating segment, as the assets are shared or commingled. Therefore, the chief operating decision maker does not regularly review any asset information by operating segment and, accordingly, asset information is not reported on a segment basis. Select information from the consolidated statements of operations and comprehensive loss as of the three months ended September 30, 2024 and 2023 is as follows: Revenues Net Loss Before Three Months Ended September 30, Three Months Ended September 30, Segment 2024 2023 2024 2023 Specialist isotopes and related services $ 1,087,695 $ — $ ( 3,722,764 ) $ ( 4,222,483 ) Nuclear fuels — — ( 3,632,625 ) — $ 1,087,695 $ — $ ( 7,355,389 ) $ ( 4,222,483 ) Select information from the consolidated statements of operations and comprehensive loss as of the nine months ended September 30, 2024 and 2023 is as follows: Revenues Net Loss Before Nine Months Ended September 30, Nine Months Ended September 30, Segment 2024 2023 2024 2023 Specialist isotopes and related services $ 2,950,348 $ — $ ( 14,637,771 ) $ ( 12,123,907 ) Nuclear fuels — — ( 8,563,904 ) — $ 2,950,348 $ — $ ( 23,201,675 ) $ ( 12,123,907 ) Fair Value of Financial Instruments Accounting guidance defines fair value, establishes a consistent framework for measuring fair value, and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the accounting guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1: Observable inputs such as quoted prices in active markets; Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. The Company’s share liability (Note 12) is measured as a Level 1 fair value on a recurring basis. There was no share liability as of December 31, 2023. The Company’s share liability was $ 416,652 as of September 30, 2024. The Company’s convertible notes payable (Note 6) is measured as a Level 3 fair value on a recurring basis and was $ 31,778,742 as of September 30, 2024 . There were no transfers among Level 1, Level 2 or Level 3 categories in the nine months ended September 30, 2024 . The following table provides a reconciliation of the Company’s liabilities measured as a Level 3 at fair value on a recurring basis using significant unobservable inputs: Convertible Balance as of December 31, 2023 — Fair value at issuance 26,558,143 Fair value adjustment 5,220,599 Settlement of liability — Balance as of September 30, 2024 $ 31,778,742 The carrying amounts of accounts payable, accrued expenses and notes payable are considered to be representative of their respective fair values because of the short-term nature of those instruments. Revenue Recognition The Company’s revenue relates to PET Labs, in which the Company acquired 51 % ownership on October 31, 2023 (Note 11). The Company recognizes revenue in accordance with Accounting Standard Codification ("ASC") Topic 606, Revenue from Contracts with Customers (“ASC 606”). The Company enters into transactions with radiopharmacy companies that are within the scope of ASC 606. The terms of these transactions include payment for delivery of nuclear medical doses for PET scanning in South Africa. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine the appropriate amount of revenue to be recognized for arrangements determined to be within the scope of ASC 606, the Company performs the following five steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect consideration it is entitled to in exchange for the goods or services it transfers to the customer. The Company evaluates a transaction’s performance obligations to determine if promised goods or services in a contract to transfer a distinct good or service to the customer and are considered distinct when (i) the customer can benefit from the good or service on its own or together with other readily available resources and (ii) the promised good or service is separately identifiable from other promises in the contract. In assessing whether promised goods or services are distinct, the Company considers whether the goods or services are integral or dependent to other goods or services in the contract. The Company determines the transaction price based on the agreed government rates for the promised goods in the contract. The consideration is recognized as revenue when control is transferred for the related goods. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition. The Company receives payments from its customers based on billing schedules established in each contract. Upfront payments and fees are recorded as deferred revenue upon receipt or when due until the Company performs its obligations under these arrangements. Amounts are recorded as accounts receivable when the Company’s right to consideration is unconditional. Accounts Receivable Accounts receivable are stated at the amount management expects to collect from outstanding balances. An allowance for expected credit losses is estimated for those accounts receivable considered to be uncollectible based upon historical experience and management's evaluation of outstanding accounts receivable. The Company maintains an allowance for expected credit losses for accounts receivable, which is recorded as an offset to accounts receivable, and changes in such are classified as selling, general and administrative expense in the Consolidated Statements of Operations and Comprehensive Loss. The Company assesses collectability by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when the Company identifies specific customers with known disputes or collectability issues. In determining the amount of the allowance for credit losses, the Company considers historical collectability based on past due status and make judgments about the creditworthiness of customers based on ongoing credit evaluations. The Company also considers customer-specific information, current market conditions, and reasonable and supportable forecasts of future economic conditions. Bad debts are written off against the allowance when identified. As of September 30, 2024, December 31, 2023 and January 1, 2023 there was no allowance for expected credit losses. Inventory The Company uses the first in, first out inventory method to account for its inventory. As of September 30, 2024 , inventory consists of raw materials and is stated at the lower of cost or net realizable value. There was no inventory as of December 31, 2023 . Property and Equipment Property and equipment include costs of assets constructed, purchased or leased under a finance lease, related delivery and installation costs and interest incurred on significant capital projects during their construction periods. Expenditures for renewals and betterments also are capitalized, but expenditures for normal repairs and maintenance are expensed as incurred. Costs associated with yearly planned major maintenance are generally deferred and amortized over 12 months or until the same major maintenance activities must be repeated, whichever is shorter. The cost and accumulated depreciation applicable to assets retired or sold are removed from the respective accounts, and gains or losses thereon are included in the statement of operations and comprehensive loss. The Company assigns the useful lives of its property and equipment based upon its internal engineering estimates, which are reviewed periodically. The estimated useful lives of the Company's property and equipment range from 3 to 10 years , or the shorter of the useful life or remaining life of the lease for leasehold improvements. Depreciation is recorded using the straight-line method. Construction in progress (Note 4) is carried at cost and consists of specifically identifiable direct and indirect development and construction costs. While under construction, costs of the property are included in construction in progress until the property is placed in service, at which time costs are transferred to the appropriate property and equipment account, including, but not limited to, leasehold improvements or other such accounts. Property and equipment acquired in the acquisition of PET Labs was measured at fair value on October 31, 2023. The fair value forms the new basis of these assets and is depreciated over the remaining estimated useful lives of the related assets. Business Combination and Asset Acquisitions The Company evaluates acquisitions of assets and other similar transactions to assess whether or not the transaction should be accounted for as a business combination or asset acquisition by first applying a screen to determine if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If the screen is met, the transaction is accounted for as an asset acquisition. If the screen is not met, further determination is required as to whether or not the Company has acquired inputs and processes that have the ability to create outputs, which would meet the requirements of a business. If determined to be a business combination, the Company accounts for the transaction under the acquisition method of accounting in accordance with ASC Topic 805 Business Combinations ("ASC 805"), which requires the acquiring entity in a business combination to recognize the fair value of all assets acquired, liabilities assumed, and any non-controlling interest in the acquiree and establishes the acquisition date as the fair value measurement point. Accordingly, the Company recognizes assets acquired and liabilities assumed in business combinations, including contingent assets and liabilities, and non-controlling interest in the acquiree based on the fair value estimates as of the date of acquisition. In accordance with ASC 805, the Company recognizes and measures goodwill as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired. The consideration for the Company’s business acquisitions may include future payments that are contingent upon the occurrence of a particular event or events. The obligations for such contingent consideration payments are recorded at fair value on the acquisition date. The contingent consideration obligations are then evaluated each reporting period. Changes in the fair value of contingent consideration, other than changes due to payments, are recognized as a gain or loss and recorded within change in the fair value of deferred and contingent consideration liabilities in the consolidated statements of comprehensive loss. If determined to be an asset acquisition, the Company accounts for the transaction under ASC 805-50, which requires the acquiring entity in an asset acquisition to recognize assets acquired and liabilities assumed based on the cost to the acquiring entity on a relative fair value basis, which includes transaction costs in addition to consideration given. No gain or loss is recognized as of the date of acquisition unless the fair value of non-cash assets given as consideration differs from the assets’ carrying amounts on the acquiring entity’s books. Consideration transferred that is non-cash will be measured based on either the cost (which shall be measured based on the fair value of the consideration given) or the fair value of the assets acquired and liabilities assumed, whichever is more reliably measurable. Goodwill is not recognized in an asset acquisition and any excess consideration transferred over the fair value of the net assets acquired is allocated to the identifiable assets based on relative fair values. Contingent consideration payments in asset acquisitions are recognized when the contingency is resolved and the consideration is paid or becomes payable (unless the contingent consideration meets the definition of a derivative, in which case the amount becomes part of the basis in the asset acquired). Upon recognition of the contingent consideration payment, the amount is included in the cost of the acquired asset or group of assets. Goodwill Goodwill represents the amount of consideration paid in excess of the fair value of net assets acquired as a result of the Company’s business acquisitions accounted for using the acquisition method of accounting. Goodwill is not amortized and is subject to impairment testing at a reporting unit level on an annual basis or when a triggering event occurs that may indicate the carrying value of the goodwill is impaired. An entity is permitted to first assess qualitative factors to determine if a quantitative impairment test is necessary. Further testing is only required if the entity determines, based on the qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. The Company will perform its annual test for goodwill as of October 31. Variable Interest Entities The Company accounts for the investments it makes in certain legal entities in which equity investors do not have (1) sufficient equity at risk for the legal entity to finance its activities without additional subordinated financial support, or (2) as a group, the holders of the equity investment at risk do not have either the power, through voting or similar rights, to direct the activities of the legal entity that most significantly impact the entity’s economic performance, or (3) the obligation to absorb the expected losses of the legal entity or the right to receive expected residual returns of the legal entity. These certain legal entities are referred to as “variable interest entities” or “VIEs.” The Company would consolidate the results of any such entity in which it determined that it had a controlling financial interest. The Company would have a “controlling financial interest” in such an entity if the Company had both the power to direct the activities that most significantly affect the VIE’s economic performance and the obligation to absorb the losses of, or right to receive benefits from, the VIE that could be potentially significant to the VIE. On a quarterly basis, the Company will reassess whether it has a controlling financial interest in any investments it has in these certain legal entities. Convertible Notes Payable Convertible notes payable are accounted for in accordance with ASC Topic 825, Financial Instruments ("ASC 825"). Upon issuance the Company has elected the fair value option to account for the convertible notes payable. Changes in fair value during the reporting period are recognized in other income (expense) in the consolidated statement of operations and comprehensive loss. Leases Leases are accounted for in accordance with ASC Topic 842, Leases ("ASC 842"). At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on specific facts and circumstances, the existence of an identified asset(s), if any, and the Company’s control over the use of the identified asset(s), if applicable. Operating lease liabilities and their corresponding right-of-use ("ROU") assets are recorded based on the present value of future lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company will utilize the incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment, and considering the region in which the ROU asset and liabilities are located. The Company has elected to combine lease and non-lease components as a single component. Operating leases are recognized on the balance sheet as ROU lease assets, lease liabilities current and lease liabilities non-current. Fixed rents are included in the calculation of the lease balances, while variable costs paid for certain operating and pass-through costs are excluded. Lease expense is recognized over the expected term on a straight-line basis. Finance leases are recognized on the balance sheet as property and equipment, finance lease liabilities current and finance lease liabilities non-current. Finance lease ROU assets and the related lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The finance lease ROU assets are amortized on a straight-line basis over the lease term with the related interest expense of the lease liability payment recognized over the lease term using the effective interest method. Impairment of Long-lived Assets Long-lived assets consist primarily of property and equipment. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset is not recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds the fair value of the assets. The Company did no t recognize any impairment losses for the three and nine months ended September 30, 2024 or 2023. Research and Development Costs Research and development costs consist primarily of fees paid to consultants, license fees and facilities costs. Nonrefundable advance payments for goods and services that will be used in future research and development activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made. All research and development costs are expensed as incurred. Selling, General and Administrative Costs Selling, general and administrative expenses consist primarily of salaries and related benefits, including stock-based compensation expense, related to the Company's executive, finance, business development, legal, human resources and support functions. Other general and administrative expenses include professional fees for auditing, tax, consulting and patent-related services, rent and utilities and insurance. Stock-based Compensation Expense Stock-based compensation expense represents the cost of the grant date fair value of employee stock awards recognized over the requisite service period of the awards (usually the vesting period) on a straight-line basis. The Company estimates the fair value of each stock-based award on the date of grant using the Black-Scholes option pricing model. The Black-Scholes option pricing model incorporates various assumptions, such as the value of the underlying common stock, the risk-free interest rate, expected volatility, expected dividend yield, and expected life of the options. Forfeitures are recognized as a reduction of stock-based compensation expense as they occur. The Company also awards restricted stock to employees and directors. Restricted stock is generally subject to forfeiture if employment terminates prior to the completion of the vesting restrictions. The Company expenses the cost of the restricted stock, which is determined to be the fair market value of the shares of common stock underlying the restricted stock at the date of grant, ratably over the period during which the vesting restrictions lapse. Stock-based compensation expense is classified in the statement of operations and comprehensive loss in the same manner in which the award recipients’ payroll costs are classified or in which the award recipients’ service payments are classified. Income Taxes Deferred income tax assets and liabilities arise from temporary differences associated with differences between the financial statements and tax basis of assets and liabilities, as measured by the enacted tax rates, which are expected to be in effect when these differences reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Prior to the acquisition of 51 % of PET Labs in October 2023, the Company had generated net losses since inception and accordingly had no t recorded a provision for income taxes. Subsequent to the acquisition of 51 % of PET Labs, the Company records the provision for income taxes for the activity from PET Labs operations. The Company follows the provisions of ASC 740-10, Uncertainty in Income Taxes, or ASC 740-10. The Company has no t recognized a liability for any uncertain tax positions. A reconciliation of the beginning and ending amount of unrecognized tax benefits has not been provided since there is no unrecognized benefit since the date of adoption. The Company has no t recognized interest expense or penalties as a result of the implementation of ASC 740-10. If there were an unrecognized tax benefit, the Company would recognize interest accrued related to unrecognized tax benefits and penalties in income tax expense. The Company has identified the United States, South Africa and Guernsey as its major tax jurisdictions. Refer to Note 15 for further details. Comprehensive Loss Comprehensive loss is defined as a change in equity during a period from transactions and other events and circumstances from non-owner sources. The Company’s comprehensive loss is comprised of net loss and the effect of currency translation adjustments. Recently Issued Accounting Pronouncements The Company has reviewed recently issued accounting pronouncements and plans to adopt those that are applicable to it. The Company does not expect the adoption of any recently issued pronouncements to have a material impact on its results of operations or financial position. In November 2023, the Financial Accounting Standards Board (“FASB") issued Accounting Standards Update (“ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 will improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses on an interim and annual basis. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods after December 15, 2024, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company’s condensed financial statements at adoption date. In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (“ASU 2024-03”) and is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. ASU 2024-03 requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. The Company is still assessing the impact of adopting this standard.

Commitments and Contingencies	8. Commitments and Contingencies Purchase of Cyclotron In November 2023, the cyclotron that the Company ordered was shipped. As of December 31, 2023 , the equipment had not been delivered; however, the Company was obligated to purchase this equipment and recorded the full cost of $ 1,653,000 in other noncurrent assets and other noncurrent liabilities on the consolidated balance sheet as of December 31, 2023. In March 2024, the cyclotron was received by the Company and is recorded as property and equipment. The financing company has paid the vendor. The Company financed the cost of this equipment and it is recorded in finance lease liabilities as of September 30, 2024. Klydon Proprietary Limited In November 2021, the Company entered into an agreement with Klydon Proprietary Limited (“Klydon”) to design and build a plant to enrich Molybdenum in South Africa (the "Turnkey Contract"). The initial phase of the project included the building of a plant that can support the production of at least 5kgs of Mo-100. The contracted cost for this phase was $ 6,800,000 . The second phase of the project included the production to be increased to 20kgs of Mo-100 with an additional cost of $ 6,000,000 . Klydon performed a portion of the services required under the Turnkey Contract; however, some services were incomplete and many of the services were not completed within the time frame required. As a result, Klydon and ASP South Africa entered into an Acknowledgement of Debt Agreement dated November 30, 2022, whereby Klydon (i) agreed to pledge its assets (the “Pledged Assets”) to ASP South Africa to secure its performance of the Turnkey Contract by December 31, 2022 , and (ii) acknowledged that ASP South Africa would suffer damages in the amount of $ 6,050,000 (“Damage Amount”) should it fail to perform. Under the Acknowledgement of Debt Agreement, the Pledged Assets would serve as collateral for Klydon’s obligation to pay the Damage Amount should Klydon fail to perform. In connection therewith, also on November 30, 2022, ASP South Africa and Klydon entered into a Deed of Security Agreement whereby, if Klydon failed to complete its obligations under the Turnkey Contract by December 31, 2022, all of Klydon’s rights of any nature to and interests of any nature in the Pledged Assets would be transferred to ASP South Africa. Klydon failed to complete its obligations under the Turnkey Contract by December 31, 2022, however, the Company did not perfect its interests in the assets until April 4, 2023. The Company did not believe that the amounts owed by Klydon were realizable, nor did the Company know the timing of any recovery payments. Therefore, a loss recovery receivable was not recorded at any time prior to April 4, 2023. On April 4, 2023, the Company perfected its interest under the Acknowledgement of Debt Agreement, pursuant to which the Company acquired certain intellectual property from Klydon (“Klydon Settlement”). In addition, the Company acquired Klydon's interest in four entities which are inactive and in the process of being dissolved. The Company has concluded that the Klydon Settlement is accounted for as an asset acquisition under ASC 805 since the assets acquired were concentrated in a single identifiable asset from a related party. In conjunction with the Klydon Settlement, the Company recorded an increase to additional paid-in capital for the settlement of all liabilities owed to Klydon at the time of settlement totaling $ 626,223 . Two individuals who are officers and board members of Klydon, one who is now an officer of ASP Isotopes Inc. and the other who is now a scientific advisor of ASP Isotopes Inc., received warrants to purchase common stock of the Company and therefore are considered related parties. See Notes 10 and 12. Share Purchase Agreement relating to PET Labs On October 31, 2023, the Company entered into a Share Purchase Agreement with Nucleonics Imaging Proprietary Limited, a company incorporated in the Republic of South Africa (the “Seller”), relating to the purchase and sale of ordinary shares in the issued share capital of Pet Labs. PET Labs is a South African radiopharmaceutical operations company, dedicated to nuclear medicine and the science of radiopharmaceutical production. Under the Purchase Agreement, the Company has agreed to purchase from the Seller 51 ordinary shares in the issued share capital of PET Labs (the “Initial Sale Shares”) (representing 51 % of the issued share capital of PET Labs) and has an option to purchase from the Seller the remaining 49 ordinary shares in the issued share capital of PET Labs (the “Option Shares”) (representing the remaining 49 % of the issued share capital of PET Labs). The Company agreed to pay to the Seller an aggregate of $ 2,000,000 for the Initial Sale Shares, of which aggregate amount of $ 500,000 was payable on the completion of the sale of the Initial Sale Shares and $ 1,500,000 is payable on demand after one calendar year from the agreement date. In January 2024, the Company agreed to pay $ 264,750 to the Seller. The balance due for the Initial Sale Shares as of September 30, 2024 is $ 1,235,250 and is recorded in other current liabilities on the condensed consolidated balance sheet. If the Company exercises its option to purchase the Option Shares (which option is exercisable from the agreement date until January 31, 2027, provided that the Initial Sale Shares have been paid for in full), the Company has agreed to pay $ 2,200,000 for the Option Shares. PET Labs Global In August 2024, PET Labs Global entered into a three-year service agreement with Cayman Enterprise City and is licensed to operate from within the Cayman Islands’ Special Economic Zone (“SEZ”). The service fee includes among other things the right to use certain office space and associated facilities within the SEZ. The Company has applied the guidance in ASC 842 and determined that this agreement is not a leasing arrangement. Management has determined that based on the nature of the combined services the expense should be recognized as incurred. The Company recorded fees under this agreement totaling $ 10,583 for the three and nine months ended September 30, 2024. Contingencies From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues liabilities for such matters when future expenditures are probable and such expenditures can be reasonably estimated. On October 25, 2022, the Company received a letter from a law firm acting on behalf of Norsk medisinsk syklotronsenter AS (“NMS”), asserting, among other things, that the grant of a license to the ASP technology to the Company by Klydon violates a pre-existing exclusive sub-license to the ASP technology granted to Radfarma. The asserted claims, arbitration and/or litigation could include claims against the Company, the Company’s licensor (Klydon), or Klydon’s present or former sub-licensors alleging infringement of intellectual property rights with respect to the ASP technology on which our company relies. The Company recorded legal costs totaling $ 78,304 which was paid to Klydon’s attorneys to settle this claim. As of December 31, 2023 , Radfarma has relinquished all claims and ASP Isotopes owns the rights to the licenses originally held by Klydon and acquired by ASP Isotopes.

The following table sets forth the computation of basic and diluted net loss per share for the three and nine months ended September 30, 2024 and 2023: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Numerator: Net loss attributable to ASP Isotopes Inc. shareholders $ ( 7,271,239 ) $ ( 4,222,483 ) $ ( 23,152,249 ) $ ( 12,123,907 ) Deemed dividend on warrant to purchase common stock — — ( 2,779,659 ) — Net loss attributable to ASP Isotopes Inc. shareholders $ ( 7,271,239 ) $ ( 4,222,483 ) $ ( 25,931,908 ) $ ( 12,123,907 ) Denominator: Weighted average common stock outstanding, basic and 61,532,172 31,147,749 51,779,067 29,954,321 Net loss per share, basic and diluted $ ( 0.12 ) $ ( 0.14 ) $ ( 0.50 ) $ ( 0.40 ) The following table sets forth the potentially dilutive securities that have been excluded from the calculation of diluted net loss per share because to include them would be anti-dilutive: As of September 30, 2024 2023 Options to purchase common stock 2,731,000 2,814,333 Warrants to purchase common stock 1,446,519 3,386,076 Unvested restricted stock 3,739,232 6,415,874 Total shares of common stock equivalents 7,916,751 12,616,283

Income Taxes

Income Taxes	9 Months Ended

Income Taxes
Income Taxes	15. Income Taxes The Company’s effective tax rate for the three months ended September 30, 2024 was 0.2 %. The Company had no income tax expense due to operating losses incurred for the three months ended September 30, 2023, as the Company had a full valuation allowance on the net deferred tax asset. The effective tax rate for the three month period ended September 30, 2024 varied from the federal statutory rate primarily due to losses in jurisdictions for which a valuation allowance is recorded. The Company’s effective tax rate for the nine months ended September 30, 2024 was 0.2 %. The Company had no income tax expense due to operating losses incurred for the nine months ended September 30, 2023, as the Company had a full valuation allowance on the net deferred tax asset. The effective tax rate for the nine months ended September 30, 2024 varied from the federal statutory rate primarily due to losses in jurisdictions for which a valuation allowance is recorded. The Company recognizes a tax benefit from an uncertain tax position when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. Income tax positions must meet a more likely than not recognition threshold to be recognized. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had no accrual for interest and penalties on the Company’s balance sheets and has not recognized interest and/or penalties in the consolidated statements of operations and comprehensive loss for the three and nine months ended September 30, 2024. Uncertain tax positions are evaluated based upon the facts and circumstances that exist at each reporting period. Subsequent changes in judgment based upon new information may lead to changes in recognition, derecognition, and measurement. Adjustments may result, for example, upon resolution of an issue with the taxing authorities or expiration of a statute of limitations barring an assessment for an issue. As of September 30, 2024, there were no uncertain tax positions. As of September 30, 2024, the Company did not recognize any interest and penalties associated with unrecognized tax benefits. Due to net operating losses incurred, tax years from inception remain open to examination by the Federal and State taxing jurisdictions to which the Company is subject. The Company is not currently under Internal Revenue Services (IRS), state or local tax examination. Ownership changes, as defined in the IRC, may limit the amount of net operating loss carryforwards that can be utilized annually to offset future taxable income pursuant to IRC Section 382 or similar provisions. Subsequent ownership changes could further affect the limitation in future years. The Company has not completed a study to assess whether a change of control has occurred or whether there have been multiple changes of control since the Company’s formation due to the significant complexity and cost associated with such study and because there could be additional changes in control in the future. As a result, the Company is not able to estimate the effect of the change in control, if any, on the Company’s ability to utilize net operating loss and research and development credit carryforwards in the future.

Basis of Presentation and Summary of Significant Accounting Policies
Unaudited Financial Information	The Company’s unaudited condensed consolidated financial statements included herein have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP"), and pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. In the Company’s opinion, the information furnished reflects all adjustments, all of which are of a normal and recurring nature, necessary for a fair presentation of the financial position and results of operations for the reported interim periods. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year or any other interim period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes for the year ended December 31, 2023 .
Basis of Presentation and Use of Estimates	The Company’s condensed consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of the Company’s condensed consolidated financial statements requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities and expenses and disclosure in the Company’s condensed consolidated financial statements and accompanying notes. The most significant estimates in the Company’s consolidated financial statements relate to stock-based compensation expense, the accounting for the acquisition of PET Labs and fair value measurement of the convertible notes payable and warrants. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results may materially differ from these estimates and assumptions.
Principles of Consolidation	The Company’s condensed consolidated financial statements include the accounts of ASP Isotopes Inc., its wholly-owned subsidiaries, the 80 % owned Enlightened Isotopes, the 51 % owned PET Labs and the 42 % owned VIE ASP Rentals. All intercompany balances and transactions have been eliminated in consolidation.
Currency and Currency Translation	The condensed consolidated financial statements are presented in U.S. dollars, the Company’s reporting currency. The functional currency of ASP Isotopes Inc. and ASP Guernsey is the U.S. dollar. The functional currency of the Company’s subsidiaries ASP South Africa and Quantum Leap Energy South Africa is the South African Rand. The functional currency of the 80 % owned Enlighted Isotopes, the 51 % owned PET Labs and the 42 % owned VIE ASP Rentals is the South African Rand. Adjustments that arise from exchange rate changes on transactions of each group entity denominated in a currency other than the functional currency are included in other income and expense in the consolidated statements of operations and comprehensive loss. Assets and liabilities of the entities with functional currency of South African Rand are recorded in South African Rand and translated into the U.S. dollar reporting currency of the Company at the exchange rate on the balance sheet date. Revenue and expenses of the entities with functional currency of South African Rand are recorded in South African Rand and translated into the U.S. dollar reporting currency of the Company at the average exchange rate prevailing during the reporting period. Resulting translation adjustments are recorded separately in stockholders’ equity as a component of accumulated other comprehensive (loss) income.
Concentration of Credit Risk and other Risks	Cash balances maintained at U.S. financial institutions may exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance limit of $ 250,000 per depositor, per insured bank for each account ownership category. Although the Company currently believes that the financial institutions with whom it does business, will be able to fulfill their commitments to the Company, there is no assurance that those institutions will be able to continue to do so. The Company has not experienced any credit losses associated with its balances in such accounts for the nine months ended September 30, 2024 and 2023. The Company's foreign subsidiaries held cash of approximately $ 2,062,000 and $ 1,963,000 as of September 30, 2024 and December 31, 2023 , respectively, which is included in cash on the consolidated balance sheets. The Company's strategic plan does not require the repatriation of foreign cash in order to fund its operations in the U.S., and it is the Company's current intention to indefinitely reinvest its foreign cash outside of the U.S. If the Company were to repatriate foreign cash to the U.S., the Company would be required to accrue and pay U.S. taxes in accordance with applicable U.S. tax rules and regulations as a result of the repatriation.
Cash and Cash Equivalents	The Company considers all highly liquid investments with original maturities at the date of purchase of three months or less to be cash equivalents. Cash and cash equivalents are stated at fair value and may include money market funds, U.S. Treasury and U.S. government-sponsored agency securities, corporate debt, commercial paper and certificates of deposit. The Company had cash equivalents of $ 186,229 in the form of money market funds as of September 30, 2024 . The Company had no cash equivalents as of December 31, 2023 .
Segment Information	As of December 31, 2023 , the Company managed its operations as a single segment, specialist isotopes and related services. Beginning in 2024, primarily as a result of increased business activities of its subsidiary, Quantum Leap Energy LLC, the Company has two operating segments: (i) nuclear fuels, and (ii) specialist isotopes and related services. The nuclear fuels segment is focused on research and development of technologies and methods used to produce high-assay low-enriched uranium (HALEU) and Lithium-6 for the advanced nuclear fuels target end market. The specialist isotopes and related services segment is focused on research and development of technologies and methods used to separate high-value, low-volume isotopes (such as C-14, Mo-100 and Si-28) for highly specialized target end markets other than advanced nuclear fuels, including pharmaceuticals and agrochemicals, nuclear medical imaging and semiconductors, as well as services related to these isotopes, and this segment includes PET Labs. The financial information is regularly reviewed by the chief operating decision maker (“CODM”) in deciding how to allocate resources. The Company’s CODM is its chief executive officer. The Company manages assets on a total company basis, not by operating segment, as the assets are shared or commingled. Therefore, the chief operating decision maker does not regularly review any asset information by operating segment and, accordingly, asset information is not reported on a segment basis. Select information from the consolidated statements of operations and comprehensive loss as of the three months ended September 30, 2024 and 2023 is as follows: Revenues Net Loss Before Three Months Ended September 30, Three Months Ended September 30, Segment 2024 2023 2024 2023 Specialist isotopes and related services $ 1,087,695 $ — $ ( 3,722,764 ) $ ( 4,222,483 ) Nuclear fuels — — ( 3,632,625 ) — $ 1,087,695 $ — $ ( 7,355,389 ) $ ( 4,222,483 ) Select information from the consolidated statements of operations and comprehensive loss as of the nine months ended September 30, 2024 and 2023 is as follows: Revenues Net Loss Before Nine Months Ended September 30, Nine Months Ended September 30, Segment 2024 2023 2024 2023 Specialist isotopes and related services $ 2,950,348 $ — $ ( 14,637,771 ) $ ( 12,123,907 ) Nuclear fuels — — ( 8,563,904 ) — $ 2,950,348 $ — $ ( 23,201,675 ) $ ( 12,123,907 )
Fair Value of Financial Instruments	Accounting guidance defines fair value, establishes a consistent framework for measuring fair value, and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the accounting guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1: Observable inputs such as quoted prices in active markets; Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. The Company’s share liability (Note 12) is measured as a Level 1 fair value on a recurring basis. There was no share liability as of December 31, 2023. The Company’s share liability was $ 416,652 as of September 30, 2024. The Company’s convertible notes payable (Note 6) is measured as a Level 3 fair value on a recurring basis and was $ 31,778,742 as of September 30, 2024 . There were no transfers among Level 1, Level 2 or Level 3 categories in the nine months ended September 30, 2024 . The following table provides a reconciliation of the Company’s liabilities measured as a Level 3 at fair value on a recurring basis using significant unobservable inputs: Convertible Balance as of December 31, 2023 — Fair value at issuance 26,558,143 Fair value adjustment 5,220,599 Settlement of liability — Balance as of September 30, 2024 $ 31,778,742 The carrying amounts of accounts payable, accrued expenses and notes payable are considered to be representative of their respective fair values because of the short-term nature of those instruments.
Revenue Recognition	The Company’s revenue relates to PET Labs, in which the Company acquired 51 % ownership on October 31, 2023 (Note 11). The Company recognizes revenue in accordance with Accounting Standard Codification ("ASC") Topic 606, Revenue from Contracts with Customers (“ASC 606”). The Company enters into transactions with radiopharmacy companies that are within the scope of ASC 606. The terms of these transactions include payment for delivery of nuclear medical doses for PET scanning in South Africa. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine the appropriate amount of revenue to be recognized for arrangements determined to be within the scope of ASC 606, the Company performs the following five steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect consideration it is entitled to in exchange for the goods or services it transfers to the customer. The Company evaluates a transaction’s performance obligations to determine if promised goods or services in a contract to transfer a distinct good or service to the customer and are considered distinct when (i) the customer can benefit from the good or service on its own or together with other readily available resources and (ii) the promised good or service is separately identifiable from other promises in the contract. In assessing whether promised goods or services are distinct, the Company considers whether the goods or services are integral or dependent to other goods or services in the contract. The Company determines the transaction price based on the agreed government rates for the promised goods in the contract. The consideration is recognized as revenue when control is transferred for the related goods. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition. The Company receives payments from its customers based on billing schedules established in each contract. Upfront payments and fees are recorded as deferred revenue upon receipt or when due until the Company performs its obligations under these arrangements. Amounts are recorded as accounts receivable when the Company’s right to consideration is unconditional.
Accounts Receivable	Accounts receivable are stated at the amount management expects to collect from outstanding balances. An allowance for expected credit losses is estimated for those accounts receivable considered to be uncollectible based upon historical experience and management's evaluation of outstanding accounts receivable. The Company maintains an allowance for expected credit losses for accounts receivable, which is recorded as an offset to accounts receivable, and changes in such are classified as selling, general and administrative expense in the Consolidated Statements of Operations and Comprehensive Loss. The Company assesses collectability by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when the Company identifies specific customers with known disputes or collectability issues. In determining the amount of the allowance for credit losses, the Company considers historical collectability based on past due status and make judgments about the creditworthiness of customers based on ongoing credit evaluations. The Company also considers customer-specific information, current market conditions, and reasonable and supportable forecasts of future economic conditions. Bad debts are written off against the allowance when identified. As of September 30, 2024, December 31, 2023 and January 1, 2023 there was no allowance for expected credit losses.
Inventory	The Company uses the first in, first out inventory method to account for its inventory. As of September 30, 2024 , inventory consists of raw materials and is stated at the lower of cost or net realizable value. There was no inventory as of December 31, 2023 .
Property and Equipment	Property and equipment include costs of assets constructed, purchased or leased under a finance lease, related delivery and installation costs and interest incurred on significant capital projects during their construction periods. Expenditures for renewals and betterments also are capitalized, but expenditures for normal repairs and maintenance are expensed as incurred. Costs associated with yearly planned major maintenance are generally deferred and amortized over 12 months or until the same major maintenance activities must be repeated, whichever is shorter. The cost and accumulated depreciation applicable to assets retired or sold are removed from the respective accounts, and gains or losses thereon are included in the statement of operations and comprehensive loss. The Company assigns the useful lives of its property and equipment based upon its internal engineering estimates, which are reviewed periodically. The estimated useful lives of the Company's property and equipment range from 3 to 10 years , or the shorter of the useful life or remaining life of the lease for leasehold improvements. Depreciation is recorded using the straight-line method. Construction in progress (Note 4) is carried at cost and consists of specifically identifiable direct and indirect development and construction costs. While under construction, costs of the property are included in construction in progress until the property is placed in service, at which time costs are transferred to the appropriate property and equipment account, including, but not limited to, leasehold improvements or other such accounts. Property and equipment acquired in the acquisition of PET Labs was measured at fair value on October 31, 2023. The fair value forms the new basis of these assets and is depreciated over the remaining estimated useful lives of the related assets.
Business Combination and Asset Acquisitions	The Company evaluates acquisitions of assets and other similar transactions to assess whether or not the transaction should be accounted for as a business combination or asset acquisition by first applying a screen to determine if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If the screen is met, the transaction is accounted for as an asset acquisition. If the screen is not met, further determination is required as to whether or not the Company has acquired inputs and processes that have the ability to create outputs, which would meet the requirements of a business. If determined to be a business combination, the Company accounts for the transaction under the acquisition method of accounting in accordance with ASC Topic 805 Business Combinations ("ASC 805"), which requires the acquiring entity in a business combination to recognize the fair value of all assets acquired, liabilities assumed, and any non-controlling interest in the acquiree and establishes the acquisition date as the fair value measurement point. Accordingly, the Company recognizes assets acquired and liabilities assumed in business combinations, including contingent assets and liabilities, and non-controlling interest in the acquiree based on the fair value estimates as of the date of acquisition. In accordance with ASC 805, the Company recognizes and measures goodwill as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired. The consideration for the Company’s business acquisitions may include future payments that are contingent upon the occurrence of a particular event or events. The obligations for such contingent consideration payments are recorded at fair value on the acquisition date. The contingent consideration obligations are then evaluated each reporting period. Changes in the fair value of contingent consideration, other than changes due to payments, are recognized as a gain or loss and recorded within change in the fair value of deferred and contingent consideration liabilities in the consolidated statements of comprehensive loss. If determined to be an asset acquisition, the Company accounts for the transaction under ASC 805-50, which requires the acquiring entity in an asset acquisition to recognize assets acquired and liabilities assumed based on the cost to the acquiring entity on a relative fair value basis, which includes transaction costs in addition to consideration given. No gain or loss is recognized as of the date of acquisition unless the fair value of non-cash assets given as consideration differs from the assets’ carrying amounts on the acquiring entity’s books. Consideration transferred that is non-cash will be measured based on either the cost (which shall be measured based on the fair value of the consideration given) or the fair value of the assets acquired and liabilities assumed, whichever is more reliably measurable. Goodwill is not recognized in an asset acquisition and any excess consideration transferred over the fair value of the net assets acquired is allocated to the identifiable assets based on relative fair values. Contingent consideration payments in asset acquisitions are recognized when the contingency is resolved and the consideration is paid or becomes payable (unless the contingent consideration meets the definition of a derivative, in which case the amount becomes part of the basis in the asset acquired). Upon recognition of the contingent consideration payment, the amount is included in the cost of the acquired asset or group of assets.
Goodwill	Goodwill represents the amount of consideration paid in excess of the fair value of net assets acquired as a result of the Company’s business acquisitions accounted for using the acquisition method of accounting. Goodwill is not amortized and is subject to impairment testing at a reporting unit level on an annual basis or when a triggering event occurs that may indicate the carrying value of the goodwill is impaired. An entity is permitted to first assess qualitative factors to determine if a quantitative impairment test is necessary. Further testing is only required if the entity determines, based on the qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. The Company will perform its annual test for goodwill as of October 31.
Variable Interest Entities	The Company accounts for the investments it makes in certain legal entities in which equity investors do not have (1) sufficient equity at risk for the legal entity to finance its activities without additional subordinated financial support, or (2) as a group, the holders of the equity investment at risk do not have either the power, through voting or similar rights, to direct the activities of the legal entity that most significantly impact the entity’s economic performance, or (3) the obligation to absorb the expected losses of the legal entity or the right to receive expected residual returns of the legal entity. These certain legal entities are referred to as “variable interest entities” or “VIEs.” The Company would consolidate the results of any such entity in which it determined that it had a controlling financial interest. The Company would have a “controlling financial interest” in such an entity if the Company had both the power to direct the activities that most significantly affect the VIE’s economic performance and the obligation to absorb the losses of, or right to receive benefits from, the VIE that could be potentially significant to the VIE. On a quarterly basis, the Company will reassess whether it has a controlling financial interest in any investments it has in these certain legal entities.
Convertible Notes Payable	Convertible notes payable are accounted for in accordance with ASC Topic 825, Financial Instruments ("ASC 825"). Upon issuance the Company has elected the fair value option to account for the convertible notes payable. Changes in fair value during the reporting period are recognized in other income (expense) in the consolidated statement of operations and comprehensive loss.
Leases	Leases are accounted for in accordance with ASC Topic 842, Leases ("ASC 842"). At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on specific facts and circumstances, the existence of an identified asset(s), if any, and the Company’s control over the use of the identified asset(s), if applicable. Operating lease liabilities and their corresponding right-of-use ("ROU") assets are recorded based on the present value of future lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company will utilize the incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment, and considering the region in which the ROU asset and liabilities are located. The Company has elected to combine lease and non-lease components as a single component. Operating leases are recognized on the balance sheet as ROU lease assets, lease liabilities current and lease liabilities non-current. Fixed rents are included in the calculation of the lease balances, while variable costs paid for certain operating and pass-through costs are excluded. Lease expense is recognized over the expected term on a straight-line basis. Finance leases are recognized on the balance sheet as property and equipment, finance lease liabilities current and finance lease liabilities non-current. Finance lease ROU assets and the related lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The finance lease ROU assets are amortized on a straight-line basis over the lease term with the related interest expense of the lease liability payment recognized over the lease term using the effective interest method.
Impairment of Long-lived Assets	Long-lived assets consist primarily of property and equipment. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset is not recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds the fair value of the assets. The Company did no t recognize any impairment losses for the three and nine months ended September 30, 2024 or 2023.
Research and Development Costs	Research and development costs consist primarily of fees paid to consultants, license fees and facilities costs. Nonrefundable advance payments for goods and services that will be used in future research and development activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made. All research and development costs are expensed as incurred.
Selling, General and Administrative Costs	Selling, general and administrative expenses consist primarily of salaries and related benefits, including stock-based compensation expense, related to the Company's executive, finance, business development, legal, human resources and support functions. Other general and administrative expenses include professional fees for auditing, tax, consulting and patent-related services, rent and utilities and insurance.
Stock-based Compensation Expense	Stock-based compensation expense represents the cost of the grant date fair value of employee stock awards recognized over the requisite service period of the awards (usually the vesting period) on a straight-line basis. The Company estimates the fair value of each stock-based award on the date of grant using the Black-Scholes option pricing model. The Black-Scholes option pricing model incorporates various assumptions, such as the value of the underlying common stock, the risk-free interest rate, expected volatility, expected dividend yield, and expected life of the options. Forfeitures are recognized as a reduction of stock-based compensation expense as they occur. The Company also awards restricted stock to employees and directors. Restricted stock is generally subject to forfeiture if employment terminates prior to the completion of the vesting restrictions. The Company expenses the cost of the restricted stock, which is determined to be the fair market value of the shares of common stock underlying the restricted stock at the date of grant, ratably over the period during which the vesting restrictions lapse. Stock-based compensation expense is classified in the statement of operations and comprehensive loss in the same manner in which the award recipients’ payroll costs are classified or in which the award recipients’ service payments are classified.
Income Taxes	Deferred income tax assets and liabilities arise from temporary differences associated with differences between the financial statements and tax basis of assets and liabilities, as measured by the enacted tax rates, which are expected to be in effect when these differences reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Prior to the acquisition of 51 % of PET Labs in October 2023, the Company had generated net losses since inception and accordingly had no t recorded a provision for income taxes. Subsequent to the acquisition of 51 % of PET Labs, the Company records the provision for income taxes for the activity from PET Labs operations. The Company follows the provisions of ASC 740-10, Uncertainty in Income Taxes, or ASC 740-10. The Company has no t recognized a liability for any uncertain tax positions. A reconciliation of the beginning and ending amount of unrecognized tax benefits has not been provided since there is no unrecognized benefit since the date of adoption. The Company has no t recognized interest expense or penalties as a result of the implementation of ASC 740-10. If there were an unrecognized tax benefit, the Company would recognize interest accrued related to unrecognized tax benefits and penalties in income tax expense. The Company has identified the United States, South Africa and Guernsey as its major tax jurisdictions. Refer to Note 15 for further details.
Comprehensive Loss	Comprehensive loss is defined as a change in equity during a period from transactions and other events and circumstances from non-owner sources. The Company’s comprehensive loss is comprised of net loss and the effect of currency translation adjustments.
Recently Issued Accounting Pronouncements	The Company has reviewed recently issued accounting pronouncements and plans to adopt those that are applicable to it. The Company does not expect the adoption of any recently issued pronouncements to have a material impact on its results of operations or financial position. In November 2023, the Financial Accounting Standards Board (“FASB") issued Accounting Standards Update (“ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 will improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses on an interim and annual basis. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods after December 15, 2024, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company’s condensed financial statements at adoption date. In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (“ASU 2024-03”) and is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. ASU 2024-03 requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. The Company is still assessing the impact of adopting this standard.
