Organization, Principal Activities, and Basis of Presentation [Abstract]
Organization, Principal Activities, and Basis of Presentation	1. Organization, Principal Activities, and Basis of Presentation Allarity Therapeutics, Inc. and Subsidiaries (the “Company”) is a clinical stage pharmaceutical company that develops drugs for the personalized treatment of cancer using drug specific companion diagnostics generated by its proprietary drug response predictor technology, DRP ® The Company’s principal operations are located at Venlighedsvej 1, 2970 Horsholm, Denmark. The Company’s business address in the Unites States is located at 24 School Street, 2 nd (a) Reverse Stock Splits On June 28 and March 24, 2023, the Company effected a 1-for-40 reverse stock split and a 1-for-35 reverse stock split, respectively, of the shares of common stock of the Company (collectively, the “Reverse Stock Splits”). All historical share and per share amounts reflected throughout the financial statements (as defined below in 1(b) and these notes to the financial statements have been adjusted to reflect both of the Reverse Stock Splits. See Note 10(a). (b) Liquidity and Going Concern The accompanying consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business. The accompanying consolidated financial statements do not reflect any adjustments relating to the recoverability and reclassification of assets and liabilities that might be necessary if the Company is unable to continue as a going concern. Pursuant to the requirements of Accounting Standard Codification (ASC) 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. This evaluation initially does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented as of the date of these financial statements, and (1) is probable that the plan will be effectively implemented within one year after the date the financial statements are issued, and (2) it is probable that the plan, when implemented, will mitigate the relevant condition or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financials are issued. Certain elements of the Company’s operating plan to alleviate the conditions that raise substantial doubt are outside of the Company’s control and cannot be included in the management’s evaluation under the requirements of ASC 205-40. Since inception, the Company has devoted substantially all its efforts to business planning, research and development, clinical expenses, recruiting management and technical staff, and securing funding via collaborations. The Company has historically funded its operations with proceeds received from its collaboration arrangements, sale of equity capital and proceeds from sales of convertible notes. The Company has incurred significant losses and has an accumulated deficit of $94.5 million as of December 31, 2023. As of December 31, 2023, our cash deposits of $166 are insufficient to fund our current operating plan and planned capital expenditures for the next 12 months. These conditions give rise to substantial doubt over the Company’s ability to continue as a going concern. Management’s plans to mitigate the conditions or events that raise substantial doubt include additional funding through public equity, private equity, debt financing, collaboration partnerships, or other sources. Considering the Company’s cash position as of March 7, 2024, the Company does not have sufficient funds for its current operations and planned capital expenditures. As discussed above the Company intends to seek capital through the sale of its securities or other sources. There are no assurances, however, that the Company will be successful in raising additional working capital, or if it is able to raise additional working capital, it may be unable to do so on commercially favorable terms. The Company’s failure to raise capital or enter other such arrangements if and when needed would have a negative impact on its business, results of operations and financial condition and its ability to develop its product candidates. Although management continues to pursue its funding plans, there is no assurance that the Company will be successful in obtaining sufficient funding to fund continuing operations on terms acceptable to the Company, if at all. Accordingly, based upon cash on hand at the issuance date of these financial statements the Company does not have sufficient funds to finance its operations for at least twelve months from the issuance date and therefore has concluded that substantial doubt exists about the Company’s ability to continue as a going concern. (c) Risks and Uncertainties The Company is subject to risks common to companies in the biotechnology industry, including but not limited to, risks of failure of preclinical studies and clinical trials, the need to obtain marketing approval for any drug product candidate that it may identify and develop, the need to successfully commercialize and gain market acceptance of its product candidates, dependence on key personnel and collaboration partners, protection of proprietary technology, compliance with government regulations, development by competitors of technological innovations, and the ability to secure additional capital to fund operations. Product candidates currently under development will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval prior to commercialization. Even if the Company’s research and development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales. (d) Emerging Growth Companies Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has chosen not to make an election to opt out of new or revised accounting standards.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies (a) Basis of Presentation The accompanying consolidated financial statements have been prepared on an accrual basis of accounting, in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the ASC and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). (b) Organization and Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries: Name Country of Incorporation Allarity Acquisition Subsidiary Inc. United States Allarity Therapeutics Europe ApS (formerly Oncology Venture Product Development ApS) Denmark Allarity Therapeutics Denmark ApS (formerly OV-SPV2 ApS) Denmark MPI Inc.* United States OV US Inc.** United States * In the process of being dissolved because inactive. ** OV US Inc. was dissolved effective November 15, 2023. All intercompany transactions and balances, including unrealized profits from intercompany sales, have been eliminated upon consolidation. (c) Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting years. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, the fair value of the Series A preferred shares, warrants, 3i Exchange Warrants, convertible debt, and the accrual for research and development expenses, fair values of acquired intangible assets and impairment review of those assets, share based compensation expense, and income tax uncertainties and valuation allowances. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed considering reasonable changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known and if material, their effects are disclosed in the notes to the consolidated financial statements. Actual results could differ from those estimates or assumptions. (d) Foreign currency and currency translation The functional currency is the currency of the primary economic environment in which an entity’s operations are conducted. The Company and its subsidiaries operate mainly in Denmark and the United States. The functional currencies of the Company’s subsidiaries are their local currency. The Company’s reporting currency is the U.S. dollar. The Company translates the assets and liabilities of its Denmark subsidiaries into the U.S. dollar at the exchange rate in effect on the balance sheet date. Revenues and expenses are translated at the average exchange rate in effect during each monthly period. Unrealized translation gains and losses are recorded as a cumulative translation adjustment, which is included in the consolidated statements of changes in redeemable convertible preferred stock and stockholders’ equity as a component of accumulated other comprehensive loss. Monetary assets and liabilities denominated in currencies other than the functional currency are remeasured into the functional currency at rates of exchange prevailing at the balance sheet dates. Non-monetary assets and liabilities denominated in foreign currencies are re-measured into the functional currency at the exchange rates prevailing at the date of the transaction. Exchange gains or losses arising from foreign currency transactions are included in the determination of net loss for the respective periods. Adjustments that arise from exchange rate translations are included in other comprehensive income (loss) in the consolidated statements of operations and comprehensive loss as incurred. The Company recorded a foreign exchange translation gain (loss) of $309 and ($121), included in accumulated other comprehensive loss for the years ended December 31, 2023 and 2022, respectively. (e) Concentrations of credit risk and of significant suppliers Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash. The Company maintains its cash in financial institutions in amounts that could exceed government-insured limits. The Company does not believe it is subject to additional credit risks beyond those normally associated with commercial banking relationships. The Company has not experienced losses on its cash accounts and management believes, based upon the quality of the financial institutions, that the credit risk regarding these deposits is not significant. The Company is dependent on third-party manufacturers to supply products for research and development activities in its programs. In particular, the Company relies and expects to continue to rely on a small number of manufacturers to supply its requirements for supplies and raw materials related to these programs. These programs could be adversely affected by a significant interruption in these manufacturing services or the availability of raw materials. (f) Cash Cash consists primarily of highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. The Company had no cash equivalents or restricted cash on December 31, 2023 and 2022. (g) Property, plant and equipment Property, plant, and equipment are stated at cost, less accumulated depreciation. Depreciation expense is recognized using the straight-line method over the estimated useful lives of the respective assets as follows: Estimated Laboratory equipment 5 years Furniture and office equipment 3 years Upon retirement or sale, the cost of assets disposed of, and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in loss from operations. As of December 31, 2023 and 2022, there have been no significant asset retirements to date. Expenditures for repairs and maintenance that do not improve or extend the lives of the respective assets are charged to expense as incurred. (h) Impairment of long-lived assets Long-lived assets consist of property, plant and equipment, and intangible assets. Long-lived assets to be held and used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations, significant negative industry or economic trends and significant changes or planned changes in the use of the assets. An impairment loss would be recognized as a loss from operations when estimated undiscounted future cash flows expected to result from the use of an asset group or the estimated return on investment are less than its carrying amount. The impairment loss would be based on the excess of the carrying value of the impaired asset group over its fair value, determined based on discounted cash flow or return on investment calculations. (i) Acquired patents Acquired patents are measured in the balance sheet at the lower of cost less accumulated amortization and impairment charges, if any. The legal costs incurred to renew or extend the term of the acquired patents are expensed as incurred. Cost comprises the acquisition price and the depreciation period are estimated at approximately 5 years with no residual value. Depreciation methods, useful lives and residual values are reviewed every year. (j) Acquired in-process research and development (IPR&D) Acquired IPR&D represents the fair value assigned to research and development assets that the Company acquired as part of a business combination and have not been completed at the acquisition date. The fair value of IPR&D acquired in a business combination is recorded on the consolidated balance sheets at the acquisition-date fair value and is determined by estimating the costs to develop the technology into commercially viable products, estimating the resulting revenue from the projects, and discounting the projected net cash flows to present value. IPR&D is not amortized, but rather is reviewed for impairment on an annual basis or more frequently if indicators of impairment are present, until the project is completed, abandoned, or transferred to a third-party. Management assesses its acquired IPR&D for impairment at year end date as well as when events and circumstances indicate there is a potential impairment. Significant quantitative indicators considered are the Company’s market capitalization, market share, length of remaining clinical trials, and projected revenue per treatment. The projected discounted cash flow models used to estimate the fair value of partnered assets and cost approach model used to estimate proprietary assets as part of the Company’s IPR&D reflect significant assumptions regarding the estimates a market participant would make to evaluate a drug development asset, including the following: ● Estimates of obsolescence of development expenditure; ● Probability of successfully completing clinical trials and obtaining regulatory approval; ● Estimates of future cash flows from potential milestone payments and royalties related to out-licensed product sales; and ● A discount rate reflecting the Company’s weighted average cost of capital and specific risk inherent in the underlying assets. Once brought into use, intangible assets are amortized over their estimated useful economic lives using the economic consumption method if anticipated future revenues can be reasonably estimated. The straight-line method is used when revenues cannot be reasonably estimated. In the years ended December 31, 2023 and 2022, the Company has recorded impairment losses of $0 and $17,571 respectively on its intangible assets. (k) Fair value measurements of financial instruments The carrying value of the Company’s financial instruments of cash, other current assets, accounts payable and accrued liabilities, approximate their fair value due to their short-term nature. The Company’s other financial instruments include an equity investment, preferred shares, convertible debt, and warrant derivative liabilities. The equity investment is adjusted to fair market value at the end of every period based upon unadjusted quoted prices. The convertible debt and derivative liabilities that are freestanding equity-linked financial instruments are fair valued at the end of every period using level 3 inputs. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC Topic 820, Fair Value Measurement (“ASC 820”), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. ASC 820 identifies fair value as the exchange price, or 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 a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tier fair value hierarchy that distinguishes between the following: ● Level 1 — defined as observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. ● Level 2 — defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and ● Level 3 — defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. (l) Segment and geographic information Operating segments are defined as components of a business for which separate discrete financial information is available for evaluation by the chief operating decision maker in deciding how to allocate resources and assess performance. The Company and its chief operating decision maker, the Company’s Chief Executive Officer, view the Company’s operations and manage its business as a single operating segment. The Company operates in two geographic areas: Denmark and the United States. (m) Research contract costs and accruals Research and development costs are expensed as incurred. Research and development expenses are comprised of costs incurred in performing research and development activities, including salaries, share-based compensation and benefits, facilities costs and laboratory supplies, depreciation, amortization and impairment expense, manufacturing expenses and external costs of outside vendors engaged to conduct preclinical development activities and clinical trials. Typically, upfront payments and milestone payments made for the licensing of technology are expensed as research and development in the period in which they are incurred. The Company has entered into various research and development contracts with companies in Europe, the United States, and other countries. These agreements are generally cancellable, and related payments are recorded as research and development expenses as incurred. The Company records accruals for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies or trials, including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. The Company’s historical accrual estimates have not been materially different from the actual costs. (n) Research and development incentives and receivable Denmark Tax Incentives Denmark allows loss making companies the opportunity to apply for a payment equal to the tax value (22%) of negative taxable income related to R&D costs. The negative taxable income is calculated on the total negative income of the companies participating in the joint taxation. Tax payment according to this rule cannot exceed an amount of DKK 5.5 million, corresponding to a tax loss relating to R&D expenditure of DKK 25 million. The tax credit is recorded as tax receivable and other income within research and development expenses. In the years ended December 31, 2023 and 2022, the Company recorded $800 and $711 in tax credits, respectively, thereby reducing research and development expenses. European Agency Grants The Company, through its subsidiaries in Denmark, from time-to-time receives reimbursements of certain research and development expenditures as part of a European agency’s research and development cost relief program. Management has assessed the Company’s research and development activities and expenditures to determine which activities and expenditures are likely to be eligible under the research and development incentive program described above. At each period end, management estimates the reimbursement available to the Company based on available information at the time. The Company records these research and development expense reimbursements as a reduction to research and development expenses in the consolidated statements of operations and comprehensive loss, as the research and development cost reimbursements are not dependent on the Company generating future taxable income, the Company’s ongoing tax status, or tax position. The Company recognizes a receivable for the research and development incentives when the relevant expenditure has been incurred, the associated conditions have been satisfied and there is reasonable assurance that the reimbursement will be received. During the years ended December 31, 2023 and 2022, the Company has not received or recorded government grants receivable. (o) Convertible debt instruments The Company follows ASC 480-10, Distinguishing Liabilities from Equity Additionally, the Company accounts for certain convertible debt (“Convertible Notes”) issued under the fair value option election of ASC 825, Financial Instruments wherein the financial instrument is initially measured at its issue-date estimated fair value and then subsequently re-measured at estimated fair value on a recurring basis at each reporting period date. The estimated fair value adjustment is recognized as other income (expense) in the accompanying consolidated statements of operations and the portion of the fair value adjustment attributed to a change in the instrument-specific credit risk is recognized as a component of other comprehensive loss. Convertible Notes are settled with shares at fair value of the stock issued with any differences recorded to other income (expense), as a gain (loss) on extinguishment. (p) Warrants When the Company issues warrants it evaluates the proper balance sheet classification to determine classification as either equity or as a derivative liability on the consolidated balance sheets. In accordance with ASC 815-40, Derivatives and Hedging-Contracts in the Entity’s Own Equity (“ASC 815-40”), the Company classifies a warrant as equity so long as it is “indexed to the Company’s equity” and several specific conditions for equity classification are met. A warrant is not considered indexed to the Company’s equity, in general, when it contains certain types of exercise contingencies or adjustments to exercise price. If a warrant is not indexed to the Company’s equity or it has net cash settlement that results in the warrants to be accounted for under ASC 480, Distinguishing Liabilities from Equity, or ASC 815-40, it is classified as a derivative liability, which is carried on the Consolidated Balance Sheet at fair value with any changes in its fair value recognized immediately in the Consolidated Statement of Operations and Comprehensive Loss. As of December 31, 2023 and 2022, the Company had warrants outstanding for share-based compensation that were classified as equity, and outstanding investor warrants that were classified as derivative liabilities and classified as “Warrant liabilities” in the Consolidated Balance Sheets. (q) Derivative financial instruments The Company does not use derivative instruments to hedge exposures to interest rate, market, or foreign currency risks. The Company evaluates all its financial instruments to determine if such instruments contain features that qualify as embedded derivatives. Embedded derivatives must be separately measured from the host contract if all the requirements for bifurcation are met. The assessment of the conditions surrounding the bifurcation of embedded derivatives depends on the nature of the host contract. Bifurcated embedded derivatives are recognized at fair value, with changes in fair value recognized in the Consolidated Statements of Operations and Comprehensive Loss each reporting period. (s) Share-based compensation The Company accounts for share-based compensation in accordance with ASC 718, Compensation — Stock Compensation (“ASC 718”). ASC 718 requires companies to estimate the fair value of equity-based payment awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service period in the Company’s Consolidated Statements of Operations and Comprehensive Loss. The Company records the expense for option awards using either a graded or straight-line method. The Company accounts for forfeitures as they occur. For share-based awards granted to both employee and non-employee consultants, the measurement date for non-employee awards is the date of grant. The compensation expense is then recognized over the requisite service period, which is the vesting period of the respective award. The Company reviews all stock award modifications including when there is an exchange of original award for a new award. In the case of stock award modifications, the Company calculates for the incremental fair value based on the difference between the fair value of the modified award and the fair value of the original award immediately before it was modified. The Company immediately recognizes the incremental value as compensation cost for vested awards and recognizes, on a prospective basis over the remaining requisite service period, the sum of the incremental compensation cost and any remaining unrecognized compensation cost for the original award on the modification date. The fair value of stock options (“options”) on the grant date is estimated using the Black-Scholes option-pricing model using the single-option approach. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions, including the option’s expected term and the price volatility of the underlying stock, to determine the fair value of the award. The Company applies the Black-Scholes model as it believes it is the most appropriate fair value method for all option awards. The Black-Scholes model requires several assumptions, of which the most significant are the share price, expected volatility and the expected award term. Expected term of options granted is calculated using the simplified method being the average between the vesting period and the contractual term to the expected term of the options in effect at the time of grant. The Company has historically not paid dividends and has no foreseeable plans to pay dividends and, therefore, uses an expected dividend yield of zero in the option pricing model. The risk-free interest rate is based on the yield of U.S. treasury bonds with equivalent terms. The Company classifies share-based compensation expense in its Consolidated Statements of Operations and Comprehensive Loss in the same way the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified. (t) Accumulated other comprehensive loss Accumulated other comprehensive loss includes net loss as well as other changes in stockholders’ equity (deficit) that result from transactions and economic events other than those with shareholders. The Company records unrealized gains and losses related to foreign currency translation and instrument specific credit risk as components of other accumulated comprehensive loss in the Consolidated Statements of Operations and Comprehensive Loss. For the years ended December 31, 2023 and 2022, the Company’s other comprehensive loss was comprised of currency translation adjustments and fair value adjustments attributable to instrument specific credit risk. (u) Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. At each reporting date, the Company evaluates whether a potential loss amount or a potential loss range is probable and reasonably estimable under the provisions of the authoritative guidelines that address accounting for contingencies. The Company expenses costs as incurred in relation to such legal proceedings as general and administrative expense within the Consolidated Statements of Operations and Comprehensive Loss. (v) Income taxes The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the consolidated financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined based on the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies. The Company accounts for uncertainty the consolidated financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not-to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the consolidated financial statements. The amount of the benefit that may be recognized is the largest amount that will more likely than not be realized upon ultimate settlement. Any provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits that are considered appropriate. The Company recognizes interest and penalties related to uncertain tax positions in other (income) expenses. (w) Computation of loss per share Basic net loss per common share is determined by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration of common stock equivalents. Diluted net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common stock and common stock equivalents outstanding for the period. The Company adjusts net loss to arrive at the net loss attributable to common stockholders to reflect the amount of dividends accumulated during the period on the Company’s redeemable convertible preferred stock, if any. The treasury stock method is used to determine the dilutive effect of the Company’s stock option grants and warrants and the if-converted method is used to determine the dilutive effect of the Company’s redeemable convertible preferred stock and Convertible Notes. For the years ended December 31, 2023 and 2022, the Company had a net loss attributable to common stockholders, and as such, all outstanding stock options, shares of redeemable convertible preferred stock, and warrants were excluded from the calculation of diluted loss per share. Under the if-converted method, convertible instruments that are in the money, are assumed to have been converted as of the beginning of the period or when issued, if later. (x) Recently issued accounting pronouncements Changes to GAAP are established by the FASB in the form of ASUs to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. All other ASUs issued through the date of these financial statements were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s consolidated financial position and results of operations.

Intangible assets Intangible assets, impairment charges and adjustments are summarized as follows: IPR&D Assets December 31, 2023 2022 Opening balance $ 9,549 $ 28,135 Impairment recognized during the period — (17,571 ) Foreign translation adjustment 322 (1,015 ) Ending balance $ 9,871 $ 9,549 As of the year ended December 31, 2023, because of continuing downward pressure on the Company’s common stock, we performed an impairment assessment and determined that no further impairment of our intangible assets is required as of December 31, 2023. As a result of both the Company’s February 15, 2022, receipt of a Refusal to File (“RTF”) from the U.S. Food and Drug Administration regarding the Company’s new drug application (“NDA”) for Dovitinib, and the current depressed state of the Company’s stock price, the Company has performed an impairment assessment on its individual intangible assets utilizing a discounted cash flow model with a weighted average cost of capital (“WACC”) of 16%, and recognized an impairment charge of $14,007 during the quarter ended March 31, 2022. During the quarter ended December 31, 2022, because of continued downward pressure on the Company’s common stock, we performed a further impairment assessment on the Company’s individual intangible asset utilizing a discounted cash flow model with a WACC of 26% and recognized a further impairment charge of $3,564. The Company’s IPR&D assets have been classified as indefinite-lived intangible assets. Our individual material development project in progress, Stenoparib, is recorded at $9,871 and $9,549 on December 31, 2023 and 2022, respectively.

Convertible Promissory Note and Accrued Interest, Net [Abstract]
Convertible promissory note and accrued interest, net	6. Convertible promissory note and accrued interest, net On April 12, 2022, Allarity Denmark re-issued a Convertible Promissory Note (the “Promissory Note”) to Novartis Pharma AG, a company organized under the laws of Switzerland (“Novartis,” and together with Allarity Therapeutics Europe ApS (“Allarity Europe”), the “License Parties”) in the principal amount of $1,000. The Promissory Note was re-issued pursuant to the First Amendment to License Agreement, with an effective date of March 30, 2022 (the “First Amendment”), entered into by and between the License Parties, which amended the License Agreement dated April 6, 2018 (the “Original Agreement”) previously entered into by the License Parties relating to the Compound (as defined in the Original Agreement). The First Amendment amends and restates Section 11.7 of the Original Agreement to add the revised Note to the list of enforceable claims in the second paragraph of Section 11.7 making the revised Note enforceable under New York law as a legal obligation of Allarity Denmark ApS (formerly OV-SPV2 ApS). All other provisions of the Original Agreement and Promissory Note were unchanged and remain in full force and effect. The Promissory Note pays simple interest on the outstanding principal amount from the date until payment in full, which interest shall be payable at the rate of 5% per annum. Interest shall be calculated on the basis of a 360-day year for the actual number of days elapsed. Due to the Company’s inability to meet its milestone payment commitments to Novartis, effective January 26, 2024, the Company has received a Termination Notice of all agreements with Novartis resulting in the promissory note and accrued interest in the amount of $300 becoming immediately due and payable. Accordingly, $1.3 million has been recorded as a current liability as of December 31, 2023. During the years ended December 31, 2023 and 2022, the Company recorded $217 and $104, respectively, to interest expense and increased the convertible promissory note liability by the same amount. The roll forward of the Promissory Note as of December 31, 2023 and 2022, is as follows: December 31, December 31, Convertible promissory note $ 1,083 $ 1,000 Less debt discount, opening (232 ) (215 ) Plus, accretion of debt discount, interest expense 51 53 Convertible promissory note, net of discount 889 838 Interest accretion, opening 245 194 Interest accrual, expense 166 51 Convertible promissory note – net, ending balance $ 1,300 $ 1,083

Secured Promissory Notes [Abstract]
Secured Promissory Notes	7. Secured Promissory Notes On November 22, 2022, the Company entered into a Secured Note Purchase Agreement (“Purchase Agreement”) with 3i, LP (“Holder”, or “3i”), whereby the Company authorized the sale and issuance of three Secured Promissory Notes (each a “Note” and collectively, the “Notes”). Effective November 28, 2022, the Company issued: (1) a Note in the principal amount of $1,667 as payment of $1,667 due to 3i, LP in Alternative Conversion Floor Amounts that began to accrue on July 14, 2022; and (2) a Note in the principal amount of $350 in exchange for cash. Effective December 30, 2022, the Company issued an additional Note in the principal amount of $650 in exchange for cash. Each Note matures on January 1, 2024, carries an interest rate of 5% per annum, and is secured by all of the Company’s assets pursuant to a security agreement (the “Security Agreement”). In addition, the Holder may exchange the Notes for the Company’s common stock at an exchange price equal to the lowest price per share of the equity security sold to other purchasers, rounded down to the nearest whole share, if the Company concludes a future equity financing prior to the maturity date or other repayment of such promissory note. Lastly, each Note and interest earned thereon may be redeemed by the Company at its option at any time or the holder may demand redemption if a) the Company obtains gross proceeds of at least $5 million in a financing in an amount of up to 35% of the gross proceeds of the financing or b) there is an Event of Default (as defined in the Note agreement). On April 19, 2023, 3i, provided the Company with a loan for $350, which was evidenced by a Secured Promissory Note dated April 19, 2023 (the “April Note”). On April 20, 2023, the Company entered into a Cancellation of Debt Agreement with 3i, which became effective as of the April Offering Closing. Upon the closing, pursuant to the terms of the Cancellation of Debt Agreement, all of the Company’s outstanding indebtedness under the Notes (as defined therein) and the Alternative Conversion Amount (as defined therein) due by the Company to 3i were paid in full. Accordingly, any and all obligations in connection therewith were extinguished without any additional further action on the part of 3i upon payment of $3,348 in cash from a portion of the proceeds from the April Offering. On June 29, 2023, the Company entered into a Secured Note Purchase Agreement with 3i, (the “June 2023 Purchase Agreement”), pursuant to which, on June 30, 2023, 3i purchased a secured promissory note for a principal amount of $350 (the “June Note”). Such note matured on July 31, 2023, and carried an interest rate of 5% per annum, and is secured by all of the Company’s assets pursuant to that certain security agreement dated June 29, 2023 (the “Security Agreement”). As contemplated by the June 2023 Purchase Agreement, the Company filed the Second Certificate of Amendment with the Delaware Secretary of State on June 30, 2023. From the proceeds of the July Offering, on July 10, 2023, the Company redeemed the June Note for $351 in cash. The roll forward of, the April Note and the June Note as of December 31, 2023 and 2022, is as follows: December 31, December 31, Secured promissory notes $ 2,644 $ 2,667 Less debt discount, opening — (35 ) Plus, accretion of debt discount, interest expense — 2 Carrying value of the Notes 2,644 2,634 Interest accretion, opening 10 — Interest accrual, expense 33 10 $ 2,687 $ 2,644 Less: repayment April 10, 2023 (2,687 ) — Plus: June 2023 Promissory Note proceeds and interest 351 — Less: July 10, 2023 repayment (351 ) — Secured promissory note, ending balance $ — $ 2,644

Preferred Stock [Abstract]
Preferred Stock	8. Preferred Stock A. Series A Preferred Stock and Common Stock Purchase Warrants (a) Amendments to Series A Preferred Stock On November 22, 2022, the Company amended Section 12 of the Certificate of Designation of Series A Convertible Preferred Stock (“Series A Preferred Stock”) to provide for voting rights. Subject to a 9.99% beneficial ownership limitation, the holders of Series A Preferred Stock shall have the right to vote on all matters presented to the stockholders for approval together with the shares of common stock, voting together as a single class, on an “as converted” basis using the “Conversion Price” (initially $9.906 per share before any adjustment) (rounded down to the nearest whole number and using the record date for determining the stockholders of the Company eligible to vote on such matters), except as required by law (including without limitation, the DGCL) or as otherwise expressly provided in the Company’s Certificate of Incorporation or the Certificate of Designations of Series A Convertible Preferred Stock. The voting rights described above expired on February 28, 2023, and thereafter holders of preferred stock shall not have voting rights except as required by law. On December 9, 2022, the Company and 3i entered into a letter agreement which provided that pursuant to Section 8(g) of the Certificate of Designations for the Series A Preferred Stock, the parties agreed that the Conversion Price was modified to mean the lower of: (i) the Closing Sale Price on the trading date immediately preceding the Conversion Date and (ii) the average Closing Sale Price of the common stock for the five trading days immediately preceding the Conversion Date, for the Trading Days through and inclusive of January 19, 2023. Any conversion which occurs shall be voluntary at the election of the Holder, which shall evidence its election as to the Series A being converted in writing on a conversion notice setting forth the then Minimum Price. Management determined that the adjustment made to the Conversion Price is not a modification of the COD which allows for adjustments to the Conversion Price at any time by the Company and the other terms of the Certificate of Designations remained unchanged. On January 23, 2023, we and 3i amended the letter agreement entered into on December 8, 2022, to provide that the modification of the term Series A Preferred Stock Conversion Price (“Series A Preferred Stock Conversion Price”) to mean the lower of: (i) the Closing Sale Price (as defined in the Certificate of Designations of Series A Preferred Stock (“Series A Certificate of Designations”)) on the trading date immediately preceding the Conversion Date (as defined in the Series A Certificate of Designations and (ii) the average Closing Sale Price of the common stock for the five trading days immediately preceding the Conversion Date, for the Trading Days (as defined in the Series A Certificate of Designations) will be in effect until terminated by us and 3i. On April 20, 2023, the Company entered into a certain Modification and Exchange Agreement (the “Exchange Agreement”) with 3i pursuant to which the parties agreed to, among other things, subject to the April Offering Closing, (i) amend the Certificate of Designations for the Series A Convertible Preferred Stock (the “Amended COD”), which among other things, eliminates the Series A Preferred Stock redemption right and dividend (except for certain exceptions as specified in the Amended COD), and provides for the conversion of Series A Preferred Stock into Common Stock at a conversion price of $0.75 which is equal to the price for a share of Common Stock sold in the April Offering, (ii) exchange 50,000 shares of Series C Preferred Stock (the “Series C Shares”) beneficially owned by 3i for 5,577 shares of Series A Preferred Stock (the “Exchange Shares”), (iii) exchange a warrant to purchase common stock issued on December 20, 2021 to 3i (the “Original Warrant”) for a new warrant (the “Exchange Warrant”), which reflects an exercise price of $30.00 (the “New Exercise Price”) and represents a right to acquire 315,085 shares of Common Stock (the “New Warrant Shares”). In addition to the satisfaction or waiver of customary and additional closing conditions set forth in the Exchange Agreement, the transactions contemplated by the Exchange Agreement were subject to (a) the occurrence of the closing of the Offering and (b) the filing of the Amended COD with the Delaware Secretary of State. On April 21, 2023, the closing of the transactions contemplated by the Exchange Agreement occurred and the Exchange Warrant and the Exchange Shares were issued to 3i, and the Original Warrant and the Series C Shares were cancelled. In addition, on April 21, 2023, the Amended COD was filed with the Delaware Secretary of State. On April 20, 2023, the Company also entered into a Cancellation of Debt Agreement as described in Note 7. Pursuant to such agreement, 1,550 shares of Series A Preferred Stock (the “Redemption Shares”) beneficially owned by 3i were redeemed in full for a purchase price of $1,652, which redemption price was paid in cash from the portion of the proceeds from the April Offering. The Company also entered into the First Amendment to the Registration Rights Agreement dated May 20, 2023 (the “RRA”), which became effective upon the April Offering Closing, to amend certain defined terms under the RRA to include the Exchange Shares, the New Warrant Shares and the Note Conversion Shares. On April 21, 2023, in connection with the transactions contemplated under the Exchange Agreement, the Company filed an Amended and Restated Certificate of Designations of Series A Convertible Preferred Stock of the Company (the “Amended and Restated Series A COD”) with the Delaware Secretary of State. The Amended and Restated Series A COD eliminates the Series A Preferred Stock redemption right and dividend (except for certain exceptions as specified therein) and provides for the conversion of Series A Preferred Stock into Common Stock at a conversion price equal to the price for a share of Common Stock sold in the April Offering, $30.00 per share, and based on a stated value of $1,080 per share. As a result of the Amended and Restated Series A COD, the Company determined that the Series A Preferred Stock met the definition of equity and reclassified it from mezzanine equity. On May 30, 2023, the Company filed an amendment to the Amended and Restated Certificate of Designations for the Series A Preferred Stock with the Delaware Secretary of State (the “Amended COD”) to amend the voting rights of the Series A Preferred Stock which among other things provided additional voting rights to the Series A Preferred Stock. Under the Amended COD, holders of the Series A Preferred Stock have the following voting rights: (1) holders of the Series A Preferred Stock have a right to vote on all matters presented at the Special Meeting together with the Common Stock as a single class on an “as converted” basis using the conversion price of $30.00 and based on stated value of $1,080 subject to a beneficial ownership limitation of 9.99%, and (2), in addition, holders of Series A Preferred Stock have granted the Board the right to vote, solely for the purpose of satisfying quorum and casting the votes necessary to adopt a reverse stock split of the Company’s issued and outstanding shares of Common Stock (the “Reverse Stock Split Proposal”) and to adjourn any meeting of stockholders called for the purpose of voting on reverse stock split (the “Adjournment Proposal”) under Delaware law, that will “mirror” the votes cast by the holders of shares of Common Stock and Series A Preferred Stock, voting together as a single class, with respect to the Reverse Stock Split Proposal and the Adjournment Proposal. The number of votes per each share of Series A Preferred Stock that may be voted by the Board shall be equal to the quotient of (x) the sum of (1) the original aggregated stated value of the Series A Preferred Stock when originally issued on December 20, 2021 (calculated based on the original stated value of $1,000 of the Series A Preferred Stock multiplied by 20,000 shares of Series A Preferred Stock) and (2) $1,200, which represents the purchase price of the Series C Preferred Stock when originally issued; divided by (y) the conversion price of $30.00. If the Board decides to cast the vote, it must vote all votes created by the Amended COD in the same manner and proportion as votes cast by the holders of Common Stock and Series A Preferred Stock, voting as single class. The Series A Preferred Stock voting rights granted to the holders thereof relating to the Reverse Stock Split Proposal and the Adjournment Proposal 2 expired automatically on July 31, 2023. In addition, among other things, the Reverse Stock Split Proposal, the effectuation of the June Reverse Stock Split, and the amendment to the Company’s Certificate of Incorporation, are subject to the consent by the holders of a majority of the then outstanding shares of Series A Preferred Stock. Such consent was received on June 27, 2023. The Series A Preferred Stock has a liquidation preference equal to an amount per Series A Preferred Stock equal to the sum of (i) the Black Scholes Value (as defined in the Warrants, which was sold concurrent with the Series A Preferred Stock) with respect to the outstanding portion of all Warrants held by such holder (without regard to any limitations on the exercise thereof) as of the date of such event and (ii) the greater of (A) 125% of the Conversion Amount of such Series A Preferred Stock on the date of such payment and (B) the amount per share such holder would receive if such holder converted such Series A Preferred Stock into Common Stock immediately prior to the date of such payment, and will be entitled to convert into shares of Common Stock at an initial fixed conversion price of $30.00 per share, subject to a beneficial ownership limitation of 9.99%. If certain defined “triggering events” defined in the Series A COD, as amended and restated and further amended, occur, or our failure to convert the Series A Preferred Stock into Common Stock when a conversion right is exercised, failure to issue our Common Stock when the Exchange Warrant is exercised, failure to declare and pay to any holder any dividend on any dividend date, then we may be required to pay a dividend on the stated value on the Series A Preferred Stock in the amount of 18% per annum, but paid quarterly in cash, so long as the triggering event is continuing. On June 6, 2023, 3i and the Company entered into a separate limited waiver and amendment agreement whereby 3i (“3i Waiver Agreement”) agreed to waive certain rights granted under a Series A Preferred Stock securities purchase agreement dated December 20, 2021, the Exchange Agreement, and the securities purchase agreement related to the April Offering in exchange for, among other things, amending the conversion price of the Series A Preferred Stock to equal the public offering price of the shares of Common Stock in the July Offering. Upon the consummation of the July Offering, the conversion price of the Series A Preferred Stock was reduced to $4.50. On July 10, 2023, the Company filed a Third Certificate of Amendment to the Amended and Restated Certificate of Designations of Series A Preferred Stock (“Third Amendment”) to effect the change to conversion price. In connection with the September 2023 Inducement Letter and the transactions contemplated therein, the Company and 3i, LP entered into a limited waiver agreement (the “Waiver”) pursuant to which 3i, LP agreed to allow the filing of the Resale Registration Statement not otherwise permitted under certain agreements with 3i, LP. In consideration of entering in the Waiver, the Company agreed to amend the “Conversion Price” of the Series A Convertible Preferred Stock to equal $1.00 as soon as practicable. On September 22, 2023, the Company filed the Fourth Certificate of Amendment to the Amended and Restated Certificate of Designations of Series A Convertible Preferred Stock (“Fourth Amendment”) with the Secretary of State of the State of Delaware to reflect the new conversion price of the Series A Preferred Stock of $1.00. Subsequent to December 31, 2023, the Series A Preferred Stock conversion price was reduced (see Note 18(c)). (b) Series A Preferred Stock Triggering Event As more specifically discussed below, a “Triggering Event” under the COD occurred on April 29, 2022, under Section 5(a)(ii) of the COD, which would have resulted in the following unless 3i, agreed to forebear and/or waive its rights under the COD: 1. An 18% per annum dividend will start to accrue on the stated value of all outstanding Preferred Shares and will continue to accrue until the Triggering Event has been cured. The accrued dividend is added to the stated value prior to the Dividend Payment Date and paid in cash on the first trading day of the Company’s next fiscal quarter. A “Late Charge” in the amount of 18% per annum will accrue on any amounts due to be paid to holders of the Preferred Shares if not paid when due, including payments that may be owed under Section (e) of the Registration Rights Agreement (“RRA”). 2. A “Triggering Event Redemption Right” will commence and remain open for a period of 20 trading days from the later of the date either the Triggering Event is cured or the receipt by 3i of the Triggering Event Notice. Under the Triggering Event Redemption Right, if elected by the holder of the Preferred Shares, the Company would be obligated to redeem all or a portion of the Preferred Shares for a minimum of 125% of the stated value of the Preferred Shares. Concurrently, under the provisions of the PIPE Warrant, if elected by 3i, the Company would be obligated to redeem the PIPE Warrant for the Black Sholes Triggering Event Value as defined in the warrant agreement. 3. A “Registration Delay Payment” will accrue on April 22, 2022 (the expiration of the Allowable Grace Period under the RRA) in the amount of 2% of 3i’s “Purchase Price” as defined in the Securities Purchase Agreement which is approximately 2% of $20 million, or $400 and will continue to accrue at 2% every 30 days thereafter. Additionally, a late charge of 2% per month will accrue on any payments that are not paid when due. The Registration Delay Payments will stop accruing when the post-effective amendment is declared effective by the SEC at which time the registration statement and its prospectus will again be available for the resale of common stock. As a result of the Company’s delay in filing its periodic reports with the SEC in 2022, a “triggering event” under Section 5(a)(ii) of the Original Series A COD, occurred on or about April 29, 2022, and because of the delay the Company was obligated to pay (i) registration delay payments under the RRA, (ii) additional amounts under the Original Series A COD, and (iii) legal fees incurred in the preparation of the Forbearance Agreement and Waiver to 3i in an aggregate amount of $539 which was paid pursuant to that certain Forbearance Agreement and Waiver with 3i. On May 4, 2022, the Company and 3i entered into a Forbearance Agreement and Waiver, dated April 27, 2022, wherein 3i confirmed that no Triggering Event as defined under the COD has occurred prior to April 27, 2022, that a Triggering Event under Section 5(a)(ii) will and has occurred on April 29, 2022, and that in consideration for the Registration Delay Payments the Company is obligated to pay under the RRA, and additional amounts the Company is obligated to pay under the COD and 3i’s legal fees incurred in the preparation of the Forbearance Agreement and Waiver in the aggregate of $539 paid upon execution of the Forbearance Agreement and Waiver, and so long as the Company pays the Registration Delay Payments that become due and payable under the RRA after the execution of the Forbearance Agreement and Waiver, 3i has agreed to forbear exercising any rights or remedies that it may have under the COD that arises as a result of a Triggering Event under Section 5(a)(ii) of the COD and Section 4(c)(ii) of the PIPE Warrant until the earlier to occur of (i) the date immediately prior to the date of occurrence of a Bankruptcy Triggering Event, (ii) the date of occurrence of any other Triggering Event under Section 5(a) of the COD (excluding any Triggering Event arising solely as a result of Section 5(a)(ii) of the COD and Section 4(c)(ii) of the PIPE Warrant), (iii) the time of any breach by the Company under the Forbearance Agreement and Waiver, (iv) the Resale Availability Date as defined therein and (v) June 4, 2022 (such period, the “Forbearance Period”). Provided that the Company is not in breach of its obligations under Forbearance Agreement and Waiver, effective as of the Trading Day immediately following the date the Company cures the Triggering Event under Section 5(a)(ii) of the COD, 3i agrees to waive any rights or remedies that it may have under the COD that arises as a result of a Triggering Event under Section 5(a) of the COD and Section 4(c)(ii) of the PIPE Warrant that may have arisen prior to the date of the Forbearance Agreement and Waiver. (c) 3i Warrants Effective April 21, 2023, pursuant to the terms of an Exchange Agreement, the PIPE Warrant was exchanged for an Exchange Warrant representing a right to acquire 315,085 shares of Common Stock, exercisable at $30.00 per share. The number of shares exercisable under the Exchange Warrant and the exercise price was subsequently adjusted in July 2023 to the right to acquire 9,452,667 shares of Common Stock, exercisable at $1.00 per share. Effective July 10, 2023, upon the closing of the July Offering, the number of shares exercisable under the Exchange Warrant and the exercise price was adjusted to 2,100,565 shares of Common Stock and $4.50 per share, respectively. Subsequently on July 26, 2023, pursuant to Section 2(e) of the Exchange Warrant, due to the event market price on the 16th day after the June Reverse Stock Split being less than the exercise price of the Exchange Warrant then in effect, the number of shares exercisable under such Warrant and the exercise price was further adjusted to 3,134,693 shares and $3.0155 per share, respectively. Effective September 14, 2023, the date of the September Induced Warrant offering, the number of shares exercisable under the Exchange Warrant and the exercise price was adjusted to 9,452,667 shares of Common Stock and $1.00 per share, respectively. On December 5, 2023, 3i exercised 5,045,466 Exchange Warrants on a cashless basis in exchange for 500,000 common shares. As of December 31, 2023, there were 4,407,201 Exchange Warrants, exercisable at $1.00, outstanding. After December 31, 2023, the exercise price of the Exchange Warrants was reduced (see Note 18(c)). (d) Accounting i. Series A Preferred Stock The Company evaluated the Series A Preferred Stock under ASC 480-10 to determine whether it represents an obligation that would require the Company to classify the instrument as a liability and determined that the Series A Preferred Stock is not a liability pursuant to ASC 480-10. Management then evaluated the instrument pursuant to ASC 815 and determined that because the holders of the Series A Preferred Stock may be entitled to receive cash, the Series A Preferred stock should be recorded as mezzanine equity given the cash redemption right that is within the holder’s control. Generally, preferred stock that are currently redeemable should be adjusted to their redemption amount at each balance sheet date. If it is probable that the equity instrument will become redeemable, the Company has the option to either accrete changes in the redemption value over the period from the date of issuance (or from the date that it becomes probable that the instrument will become redeemable, if later) to the earliest redemption date of the instrument or to recognize changes in the redemption value immediately as they occur and adjust the carrying amount of the instrument to equal the redemption value at the end of each reporting period. The Company recognizes changes in redemption value when redemption becomes probable to occur. Through December 9, 2022, the derivative scope exception under ASC 815 was not met because a settlement contingency was not indexed to the Company’s stock. Therefore, the redemption feature (derivative liability) was bifurcated from the Series A Preferred Stock and recorded as a derivative liability. The fair value of the Series A Preferred Stock Redemption Feature (the “Redemption Feature”) derivative is the difference between the fair value of the Series A Preferred Stock with the Redemption Feature and the Series A Preferred Stock without the Redemption Feature. The Series A Preferred Stock Redemption Feature has been valued with a Monte Carlo Simulation model, using the inputs as described in Note 9(b). Subsequent to December 9, 2022, because of the agreed conversion price adjustment, although bifurcation of the conversion feature is still required, the value of the derivative has been determined to be immaterial since the conversion price will always be at market. Additionally, because the Series A redemption terms were amended to be entirely within the Company’s control, they have now been classified as permanent equity. Management has fair valued the Series A Preferred Stock prior to and after its modification and because the change in fair value was greater than 10%, has made a policy election to treat the amendment as an extinguishment. Accordingly, the difference in fair value has been recorded as a deemed dividend and reduction in additional paid in capital. Deemed Dividends In the year ended December 31, 2023, the Company, has recorded $8,392 in deemed dividends resulting from using the Black-Scholes model to determine the fair value the Company’s Series A Preferred shares as follows: i. $3,328 on the elimination of Series A redemption rights as of April 21, 2023, ii. $3,959 on the Exchange of 50,000 Series C Preferred Stock for 5,577 Series A Preferred Stock; iii. $206 on the July 10, 2023, modification of Series A Preferred Stock; iv. $526 on the redemption of Series A Preferred Stock; and v. $373 on the September 14, 2023 modification of Series A Preferred Stock. As of the dates noted below, the Company used the Black-Scholes option pricing model to determine the fair values using the following inputs: Series A Preferred September 14, Series A Preferred July 10, Number of shares valued 1,417 6,047 Stock Price $ 1.00 $ 3.40 Exercise price pre-modification $ 4.50 $ 8.00 Exercise price post-modification $ 1.00 $ 4.50 Risk fee rate 5.37 % 5.28 % Dividend 0 % 0 % Volatility 119 % 140 % During the year ended December 31, 2023, the Company used the Black-Scholes option pricing model to determine the fair values using the following inputs: Original Debt Settled Series C Number of shares valued 4,239 5,577 486 Stock Price at April 21, 2023 post 40 to 1 split $ 20.40 $ 20.40 $ 20.40 Exercise price $ 30.00 $ 30.00 $ 30.00 Risk fee rate 5.1 % 5.1 % 5.1 % Dividend 0 % 0 % 0 % Expected liquidity event September 15, 2023 September 15, 2023 September 15, 2023 Volatility 156 % 156 % 156 % ii. 3i Warrants The 3i Warrants were identified as a freestanding financial instrument and meet the criteria for derivative liability classification, initially measured at fair value. Subsequent changes in fair value are recognized through earnings for as long as the contracts continue to be classified as a liability. The measurement of fair value is determined utilizing an appropriate valuation model considering all relevant assumptions current at the date of issuance and at each reporting period (i.e., share price, exercise price, term, volatility, risk-free rate and expected dividend rate). (f) Series A Preferred Stock Conversions i. Year ended December 31, 2023 During the year ended December 31, 2023, 3i exercised its option to convert 12,052 shares of Series A Preferred stock for 241,893 shares of common stock at the fair value of $3,899. From the proceeds of the July Offering, on July 10, 2023, the Company redeemed (i) 4,630 shares of Series A Preferred Stock held by 3i, for $5,000, and (ii) the 3i June Promissory Note (as defined below) for $351 in cash. As a result of the payment, the 3i June Promissory Note was paid in full on July 10, 2023. As of December 31, 2023, the Company had 1,417 shares of Series A Preferred Stock issued and outstanding. (See Note 18(b).) ii. Year ended December 31, 2022 During the year ended December 31, 2022, 3i exercised its option to convert 6,214 shares of Series A Preferred stock for 5,573 shares of common stock. As of December 31, 2022, we had 13,586 shares of Series A Preferred Stock issued and outstanding. The fair value of the derivative liability associated with the Series A Preferred Stock converted during the year ended December 31, 2022, as determined by Monte Carlo simulations, was $954. Because the latest nine conversions in the period January 1, 2022, through December 9, 2022, were completed at less than the agreed floor price, we recorded a floor price liability and recognized a corresponding reduction of additional paid in capital, as follows: i. During the six months ended June 30, 2022, $1,511 (paid in cash prior to June 30, 2022); ii. During the three months ended September 30, 2022, $1,646 (see Note 9(b)); iii. On December 9, 2022, we issued 86 shares of Common Stock to the Investor upon the conversion of 222 Conversion Shares and recorded a floor price liability of $264. Additionally, because the Company’s average daily dollar volume of stock trading was less than $2.5 million during a ten-day period in January 2022, the Company has recorded a one-time deemed dividend of 8% in the amount of $1,572 on preferred stock converted between February 1, 2022 and March 31, 2022 and the balance of Series A Preferred Stock outstanding as at March 31, 2022 as an increase to the value of the Series A Preferred Stock and a reduction of additional paid in capital. In addition, under the terms of the Registration Rights Agreement (“RRA”), during the year ended December 31, 2022, the Company has also paid 3i an additional $800 in Registration Delay Payments. The accounting for the Series A Preferred Stock and 3i Exchange Warrants is illustrated in the table below: Consolidated Balance Sheets Consolidated 3i Series A Series A Additional Fair value Balances at December 31, 2022 $ 374 $ 2,001 $ — $ (3,756 ) $ — Conversion of 9,247 Series A Preferred Stock, net — (1,377 ) (2,522 ) 3,909 — Elimination of redemption rights on Series A Preferred stock; deemed dividend of $3,328 — (624 ) 3,952 (3,328 ) — Redemption of 6,180 Series A Preferred Stock, deemed dividend of $526 — — (5,919 ) (526 ) — Issuance of 486 Series A Preferred stock as repayment of $350 debt; $103 charged to interest expense — — 453 — — Exchange of 50,000 Series C Preferred Stock for 5,577 Series A Preferred Stock; deemed dividend of $3,959 — — 5,199 (3,959 ) — Deemed dividend on July 10, 2023 modification — — 206 (206 ) — Deemed dividend on September 14, 2023 modification — — 373 (373 ) — Cashless redemption of 5,045,446 Exchange Warrants for 500,000 common shares (1,031 ) — — 1,031 — Fair value adjustment 1,477 — — — (1,477 ) Balances, December 31, 2023 $ 820 $ — $ 1,742 $ ( 7,208 ) $ (1,477 ) The accounting for the Series A Preferred Stock and 3i Exchange Warrants is illustrated in the table below: Consolidated Balance Sheets Consolidated 3i Series A Series A Additional Fair value Balances at December 31, 2021 $ 11,273 $ 7,181 $ 632 $ 80 $ — Conversion of 6,214 shares of Series A Preferred stock into common stock — — (203 ) 203 — Reclassification of derivative liability relating to converted Series A Preferred Stock — (954 ) — 954 — Floor price adjustment on conversion of shares of Series A Preferred Stock — — — (3,421 ) — 8% deemed dividend on Preferred Stock — — 1,572 (1,572 ) — Fair value adjustment (10,899 ) (6,227 ) — — 17,125 Balances, December 31, 2022 $ 374 $ — $ 2,001 $ (3,756 ) $ 17,125 * Valuation of the Series A Preferred Derivative Liability is discussed in Note 9(b). B. Series C Convertible Preferred Stock On February 28, 2023, the Company entered into a Securities Purchase Agreement (the “SPA”) with 3i, L.P. for the purchase and sale of 50,000 shares of Series C Convertible Redeemable Preferred Stock (“Series C Preferred Stock”) at a purchase price of $24.00 per share, for a subscription receivable in the aggregate amount equal to the total purchase price of $1.2 million (the “Offering”). The 50,000 shares of Series C Preferred Stock (the “Shares”) are convertible into shares of the Company’s common stock, subject to the terms of the COD. The conversion price for the Series C Preferred Stock is initially equal the lower of: (i) $0.182 ($6.37 post reverse stock split), which is the official closing price of the Common Stock on the Nasdaq Global Market (as reflected on Nasdaq.com) on the Trading Day (as defined in the COD) immediately preceding the Original Issuance Date (as defined in the COD); and (ii) the lower of: (x) the official closing price of the Common Stock on the Nasdaq Global Market (as reflected on Nasdaq.com) on the Trading Day immediately preceding the Conversion Date or such other date of determination; and (y) the average of the official closing prices of the Common Stock on the Nasdaq Global Market (as reflected on Nasdaq.com) for the five Trading Days immediately preceding the Conversion Date (as defined in the COD) or such other date of determination, subject to adjustment (the “Conversion Price”). In no event will the Conversion Price be less than $0.0370 ($1.295 post reverse stock split) (the “Floor Price”). In the event that the Conversion Price on a Conversion Date would have been less than the applicable Floor Price if not for the immediately preceding sentence, then on any such Conversion Date the Company will pay the Holder an amount in cash, to be delivered by wire transfer out of funds legally and immediately available therefor pursuant to wire instructions delivered to the Company by the Holder in writing, equal to the product obtained by multiplying (A) the higher of (I) the highest price that the Common Stock trades at on the Trading Day immediately preceding such Conversion Date and (II) the applicable Conversion Price and (B) the difference obtained by subtracting (I) the number of shares of Common Stock delivered (or to be delivered) to the Holder on the applicable Share Delivery Date with respect to such conversion of Series C Preferred Stock from (II) the quotient obtained by dividing (x) the applicable Conversion Amount that the Holder has elected to be the subject of the applicable conversion of Series C Preferred Stock, by (y) the applicable Conversion Price without giving effect to clause (x) of such definition. The Offering closed on February 28, 2023. In connection with the Offering, concurrently with the SPA, the Company entered into a registration rights agreement with 3i (the “RRA”) pursuant to which the Company is required to file a registration statement with the SEC to register for resale the shares of Common Stock that are issued upon the potential conversion of the Shares. Under the terms of the RRA, if the Company fails to file an Initial Registration Statement (as defined in the RRA) on or prior to its Filing Date (as defined in the RRA), or fail to maintain the effectiveness of the registration statement beyond defined allowable grace periods set forth in the RRA, we will incur certain registration delay payments, in cash and as partial liquidated damages and not as a penalty, equal to 2.0% of 3i’s subscription amount of the Shares pursuant to the SPA. In addition, if we fail to pay any partial liquidated damages in full within seven days after the date payment, we will have to pay interest at a rate of 18.0% per annum, accruing daily from the date such partial liquidated damages are due until such amounts, plus all such interest thereon, are paid in full. The Company has also agreed to pay all fees and expenses incident to the performance of the RRA, except for any broker or similar commissions. In connection with the Offering, the Company and 3i entered into a limited waiver agreement (the “Waiver”) pursuant to which 3i confirmed that the sale and issuance of the Shares will not give rise to any, or trigger any, rights of termination, defaults, amendment, anti-dilution or similar adjustments, acceleration or cancellation under agreements with 3i.

Derivative Liabilities	9. Derivative Liabilities (a) Continuity of Warrant Derivative Liabilities The derivative liabilities are measured at fair value at each reporting period and the reconciliation of changes in fair value in the years ended December 31, 2023 and 2022, is presented in the following tables: Common 3i Exchange 3i Fund Issued December 20, 2021 Balance as of January 1, 2022 $ — $ 11,273 $ 7,181 Change in fair value — (10,899 ) (6,227 ) Amount transferred to Equity — — (954 ) Balance as of December 31, 2022 $ — $ 374 $ — Fair value per 3i Warrant / Series A Preferred share issuable at period end $ — $ 6.48 $ — Balance as of January 1, 2023 $ — $ 374 $ — Issuance date fair value of April, July & September 2023 Common share purchase warrants 15,161 — — Modifications to fair value upon exercise 592 — — Fair value adjustments (11,911 ) 1,477 — Amount transferred to Equity (1,579 ) (1,031 ) — Balance as of December 31, 2023 $ 2,263 $ 820 $ — Fair value per Common warrant / 3i Warrant / Series A Preferred share issuable at period end $ 0.44 $ 0.19 $ — (b) Series A Preferred Stock Conversion Feature – Valuation Inputs The following inputs were used for the Series A Preferred Stock conversions recorded in the year ended December 31, 2022, and the fair value of the Series A Preferred derivative liability determined at September 30, 2022: January 1, Initial exercise price $9.05 - $9.91 Stock price on valuation date $1.10 - $10.75 Risk-free rate 1.03% - 4.23% Time to exercise (years) 2.22 - 2.96 Equity volatility 70% - 114% Probability of volume failure 93% - 99% Rounded 10-day average daily volume (in 1,000’s) $297 - $873 * The agreed conversion price adjustment (see Note 8(d) i.) resulted in the Series A Preferred liability value derivative being valued at zero at December 9, 2022. Consequently, there were no conversions subsequent to September 30, 2022, which impacted the Series A derivative liability. (c) 3i Warrants – Valuation Inputs On December 5, 2023, 3i converted 5,045,446 Exchange Warrants on a cashless basis for 500,000 shares of our Common Stock. Therefore, we utilized the reset strike options Type 2 model by Espen Garder Haug and Black-Scholes Merton models to estimate the fair value of the outstanding 9,452,667 Exchange Warrants immediately before 3i’s conversion to be approximately $1,931 as of December 5, 2023. Accordingly, we recorded a $2,015 reduction in the fair value of the 9,452,667 Exchange Warrants as a credit to change in fair value of warrants in our consolidated statement of comprehensive loss and $1,031, being the fair value of the 5,045,446 converted Exchange Warrants, was recorded as a credit to additional paid in capital. On December 31, 2023 and 2022, the Company utilized the reset strike options Type 2 model by Espen Garder Haug and Black-Scholes Merton models to estimate the fair value of the 3i Exchange Warrants to be approximately $820 and $374, respectively. The 3i Exchange Warrants were valued at December 31, 2023, December 5, 2023, and December 31, 2022, using the following inputs: December 31, December 5, December 31, Exercise price $ 1.00 $ 1.00 $ 9.91 Stock price on valuation date $ 0.55 $ 0.58 $ 0.29 Risk-free rate 4.71 % 4.92 % 4.33 % Expected life of the Warrant to convert (years) 0.97 1.04 1.97 Rounded annual volatility 127 % 123 % 131 % Timing of liquidity event Q1 - 2024 March 31, 2024 March 15, 2023 Expected probability of event 10 % 10 % 100 %

Stockholders’ Equity [Abstract]
Stockholders’ Equity	10. Stockholders’ Equity (a) Amendments to Certificate of Incorporation and Reverse Stock Splits On March 20, 2023, an amendment to Allarity Therapeutics, Inc.’s Certificate of Incorporation, as amended (the “Certificate of Incorporation”), to increase the number of authorized shares from 30,500,000 to 750,500,000, and to increase the number of shares of common stock (the “Common Stock”) from 30,000,000 to 750,000,000 (the “Share Increase”) was approved by the stockholders of record entitled to vote in person or by proxy at the Special Meeting of Stockholders on March 20, 2023 (the “2023 Special Meeting”). Upon receipt of the required stockholder approval, on March 20, 2023, Allarity Therapeutics, Inc. (the “Company”), filed a Third Certificate of Amendment to the Certificate of Incorporation (the “Certificate of Amendment”) with the Secretary of State of the State of Delaware (the “Delaware Secretary of State”) to effect the Share Increase. On March 23, 2023, the Company filed a Third Certificate of to the Certificate of Incorporation with the Delaware Secretary of State to effect a 1-for-35 share consolidation of our common stock on March 24, 2023 (“March Reverse Stock Split”). No fractional shares were issued in connection with the March Reverse Stock Split. If, as a result of the March Reverse Stock Split, a stockholder would otherwise have been entitled to a fractional share, each fractional share was rounded up to the next whole number. The March Reverse Stock Split resulted in a reduction of our outstanding shares of common stock from 34,294,582 to 979,846. As a result of the filing of the Certificate of Amendment, the Company is authorized to issue 750,500,000 shares, consisting of (i) 750,000,000 shares of common stock, par value $0.0001 per share, and (ii) 500,000 shares of preferred stock, par value of $0.0001 per share. On June 23, 2023, we held a Special Meeting of Stockholders (the “Special Meeting”) for our stockholders of record of our outstanding shares of Common Stock and Series A Preferred Stock. At the Special Meeting, the stockholders of Common Stock and Series A Preferred Stock approved an amendment to our Certificate of Incorporation, to, at the discretion of the board, effect a reverse stock split with respect to our issued and outstanding Common Stock at a ratio between 1-for-15 and 1-for-50 (the “June Reverse Stock Split Proposal”). Upon stockholder approval, the Board of Directors determined a ratio of 1-for-40 for the reverse stock split (the “June Reverse Stock Split”). On June 28, 2023, the Company filed a Fourth Certificate of Amendment of the Certificate of Incorporation to effect the June Reverse Stock Split on June 28 2023 (the “June Share Consolidation”). No fractional shares were issued in connection with the June Share Consolidation. If, as a result of the June Share Consolidation, a stockholder would otherwise have been entitled to a fractional share, each fractional share was rounded up to the next whole number. The June Share Consolidation resulted in a reduction of our outstanding shares of Common Stock from 20,142,633 to approximately 503,566. The par value of our authorized stock remained unchanged at $0.0001. As of the date of these financial statements all references to our common stock have been retrospectively adjusted to reflect both the March Share Consolidation and the June Share Consolidation (the “Share Consolidations”), unless otherwise noted. (b) Redemption of Series B Preferred Stock Upon conclusion of the 2023 Annual Meeting of Stockholders on February 3, 2023, all the 190,786 shares of Series B Preferred Stock outstanding were automatically redeemed, with the holders of the Series B Preferred Stock only having a right to receive the purchase price for the redemption, which was $0.01 per share of Series B Preferred Stock. (c) Series C Preferred Stock On February 24, 2023, the Company filed a Certificate of Designation of Preferences, Rights and Limitations of Series C Convertible Redeemable Preferred Stock (the “Series C COD”) with the Delaware Secretary of State designating 50,000 shares of its authorized and unissued preferred stock as Series C Preferred Stock with a stated value of $27.00 per share. On February 28, 2023, the Company filed a Certificate of Amendment to the Series C COD (the “COD Amendment”) to clarify the terms of conversion price and floor price based on definitions provided in the Series C COD (the COD Amendment, together with the Series C COD, the “COD”). Each share of Series C Preferred Stock has 620 votes and is subject to certain redemption rights and voting limitations. Pursuant to the terms of a Modification and Exchange Agreement dated April 20, 2023, by and between 3i and the Company, effective April 21, 2023, 3i exchanged 50,000 shares of Series C Preferred Stock (the “Series C Shares”) beneficially owned by 3i for 5,577 shares of Series A Preferred Stock. (d) Common Share, Pre-Funded Warrant and Common Share Purchase Warrant issuances In April 2023, the Company issued 71,734 shares of our Common Stock and 71,734 common stock purchase warrants, each exercisable for one share of Common Stock, at a combined public offering price of $30.00, and 178,267 pre-funded warrants, each exercisable for one share of Common Stock, and 178,267 common stock purchase warrants, each exercisable for one share of common stock only (the common stock purchase warrants sold in the public offing hereinafter referred to as the “April 2023 Common Warrants”) at a combined public offering price of $30.00 less the $0.001 for the pre-funded warrants, for aggregate gross proceeds of approximately $7.5 million, before deducting placement agents fees and offering expenses payable by the Company, or the April Offering. The Common Stock, pre-funded warrant and April 2023 Common Warrants were sold pursuant to a securities purchase agreement with the purchaser signatory thereto or pursuant to the prospectus which was part of an effective registration statement on Form S-1 filed with the SEC. The Common Stock, pre-funded warrants and April 2023 Common Warrants are immediately separable and were issued separately in the offering. As of June 30, 2023, all pre-funded warrants from the April Offering were exercised in exchange for 178,267 common shares. In July 2023, the Company issued 357,223 shares of our Common Stock pre-funded warrants to purchase up to 2,087,222 shares of common stock (the “July Pre-Funded Warrants”), and common warrants to purchase up to 2,444,445 shares of Common Stock (the “2023 July Common Warrants”) at an effective combined purchase price of $4.50 per share and related common stock purchase warrants for aggregate gross proceeds of approximately $11 million, before deducting placement agent fees and offering expenses payable by the Company of approximately $920 on July 10, 2023 (“July Offering”). The securities in the July Offering were registered pursuant to the registration statement on Form S-1, as amended (File No. 333-272469). The purchase price of each July Pre-Funded Warrant and 2023 July Common Warrant was equal to $4.50 less the $0.001 per share exercise price of each Pre-Funded Warrant. Such securities were sold pursuant to a securities purchase agreement with the purchaser signatory thereto or pursuant to the prospectus which was part of an effective registration statement on Form S-1 filed with the SEC. As of September 30, 2023, all July Pre-Funded Warrants were exercised prior in exchange for 2,087,222 common shares. In September 2023, the Company entered into an Inducement Letter dated September 14, 2023 (the “Inducement Letter”) with each of Armistice Capital Master Fund Ltd. and Sabby Volatility Warrant Master Fund, Ltd. (“September Investors”) who were the holders of existing common stock purchase warrants issued (i) in the April Offering (the “April Warrants”) and (ii) in the July Offering (the “July Warrants” and together with the April Warrants, the “Existing Warrants”). Pursuant to the Inducement Letter, the September Investors agreed to exercise for cash their respective Existing Warrants to purchase an aggregate of up to 2,438,889 shares of the Company’s Common Stock (the “Existing Warrant Shares”), at a reduced exercise price of $1.00 per share, in consideration for the Company’s agreement to issue a new unregistered common stock purchase warrant to purchase up to a number of shares of Common Stock equal to 200% of the number of Existing Warrant Shares issued, or the Inducement Warrants, pursuant to each Existing Warrant exercise (the “Inducement Warrant Shares”), exercisable for 5 years and six months from the issue date, at an exercise price of $1.00, subject to adjustment. Upon execution of the Inducement Letter by each of the September Investors the Company issued the Inducement Warrants to the September Investors pursuant to a private placement (the “September Private Placement”). As of December 31, 2023, the Company received approximately $2,962 million, net of costs in exchange for the exercise of 2,438,889 Existing Warrants. (e) April 2023, July 2023 and September 2023 Common Warrants Subject to certain ownership limitations, the April 2023 Common Warrants are exercisable immediately from the date of issuance. The April 2023 Common Warrants have an exercise price of $34.00 per share and expire on the 5 year anniversary of the date of issuance, April 21, 2023, unless otherwise agreed upon by us and holder of the warrant. The exercise price of the April 2023 Common Warrants is subject to certain adjustments, including stock dividends, stock splits, combinations and reclassifications of the Company’s Common Stock. In the event of a fundamental transaction, as described in the April 2023 Common Warrants, each of the holders of the April 2023 Common Warrants will have the right to exercise its April 2023 Common Warrant and receive the same amount and kind of securities, cash or property as such holder would have been entitled to receive upon the occurrence of such fundamental transaction if such holder had been, immediately prior to such fundamental transaction, the holder of shares of the Company’s Common Stock issuable upon the exercise of its April 2023 Common Warrant. Additionally, in the event of a fundamental transaction within the Company’s control, as described in the April 2023 Common Warrants, each holder of the April 2023 Common Warrants will have the right to require the Company to repurchase the unexercised portion of its April 2023 Common Warrant at its fair value using a variant of the Black Scholes option pricing formula. In the event of a fundamental transaction that is not within the Company’s control, each holder of the April 2023 Common Warrants will have the right to require the Company or a successor entity to redeem the unexercised portion of its April 2023 Common Warrant for the same consideration paid to the holders of the Company’s Common Stock in the fundamental transaction at the unexercised April 2023 Common Warrant’s fair value using a variant of the Black Scholes option pricing formula. Pursuant to a securities purchase agreement entered into with certain investors in the April Offering, we agreed that for a period of 90 days from the close of the April Offering, that we would not issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or securities convertible or exercisable into Common Stock or file a registration statement with the SEC to register our securities, subject to certain exceptions. The investors to the securities purchase agreement in the April Offering, excluding 3i, have agreed to waive that provision and permit the July offering of our Common Stock, pre-funded warrants and common warrants (“Offering Waiver”) in exchange for (i) the repricing of the exercise price of the April 2023 Common Warrant to the exercise price of the common warrant offered in the July Offering if the exercise price of the common warrant is lower than the then-current April 2023 Common Warrant exercise price; and (ii) extending the termination date of the April 2023 Common Warrant to the date of termination of the common warrants offered in the July Offering As a result of the July Offering, investors to the securities purchase agreement in the April Offering, excluding 3i, had the exercise price of their April 2023 Common Warrant reduced to $4.50 per share and the exercise period extended to on or around July 10, 2028. 3i and the Company entered into a separate limited waiver and amendment agreement, as discussed above. We used the Black-Scholes option pricing model to fair value the April Common Warrants as of July 10, 2023, using the Black-Scholes option pricing model and recorded the incremental value of $202 as a fair value modification cost in other income (expenses). Management considered the September, July and April Common Warrants, which do not represent outstanding shares, and determined that they contain certain contingent redemption features, outside of the Company’s control and at the election of the Holder, which may require the Company to repurchase the September, July and April Common Warrants or Warrant Shares in exchange for cash (i.e., puttable) in an amount as defined in the Warrant Agreements. The Company concluded that the September, July, and April Common Warrants represent liabilities under ASC 480. Accordingly, the September, July and April Common Warrants have been initially recorded at their fair value of $4,189, $6,824, and $4,148 respectively using the Black-Scholes option pricing model and as a reduction of additional paid in capital. Additionally, the total July financing cost of $902 has been proportionately allocated to financing costs and additional paid in capital in the amounts of the amount of $571 and $349, respectively; and the total April financing cost of $679 has been proportionately allocated to the finance expense and additional paid in capital in the amounts of $376 and $303, respectively. The September financing cost of $198 has been allocated to a finance expense in general and administration costs. On September 14, 2023, the exercise prices of the July and April Common Warrants were reduced to $1.00 per share and the exercise period extended to on or about September 14, 2028. We used the Black-Scholes option pricing model to fair value the July and April Common Warrants as of September 14, 2023, using the Black-Scholes option pricing model and recorded the incremental value of $389 as a fair value modification cost in other income (expenses). On November 8, December 1, and December 5, 2023, a total of 373,000, 266,000 and 1,373,534 July warrants were exercised, respectively, and we used the Black-Scholes option pricing model to fair value the July warrants at $143, $124, and $233, respectively. On December 5, 2023, a total of 83,333 April warrants were exercised, and we used the Black-Scholes option pricing model to fair value the April warrants at $22. As of December 31, 2023, we used the Black-Scholes option pricing model to fair value the outstanding September, July, and April Common share purchase warrants of 4,877,778, 222,223, and 33,333, respectively, at $2,154, $95 and $14, respectively. Inputs used in the above noted Black-Scholes valuation models for the April, July and September Common Warrants are as follows: December 5, December 1, November 8, Initial exercise price $ 1.00 $ 1.00 $ 1.00 Stock price on valuation date $ 0.58 $ 0.59 $ 0.50 Risk-free rate 4.14 % 4.14 % 4.14 % Term of Warrant (in years) 4.60 4.61 4.67 Rounded annual volatility 123 % 122 % 122 % December 31, September 14, July 10, April 21, Initial exercise price $ 1.00 $ 1.00 - $4.50 $ 4.50 - $34.00 $ 34.00 Stock price on valuation date $ 0.55 $ 1.00 $ 3.40 $ 20.40 Risk-free rate 3.84 % 4.32% - 4.35 % 4.16% - 4.19 % 3.70 % Term of Warrant (in years) 4.53 - 5.20 4.82 4.78 - 5.00 5.00 Rounded annual volatility 125 % 127 % 122% - 140 % 126 % ii.

The agreement also provides for a joint development committee consisting of six members, three appointed by us and three appointed by Eisai. One of our members of the joint development committee is designated chair of the committee and has the power to break any deadlock in decisions by the committee that must be made by a majority vote with each representative having one vote.

Eisai also has the right to terminate the agreement upon written notice of a material breach of the agreement by us that is not cured within 90 days (30 days for a payment default) or if we file for bankruptcy. By an amendment effective as of August 3, 2021, and executed by Eisai on August 23, 2021, Eisai also has the right to terminate the agreement if we do not complete a Phase 2 clinical trial before December 31, 2022, unless we elect to pay a $1,000 extension payment (“Extension Payment”). Notwithstanding the foregoing, in the event we fail to enroll and dose at least 30 patients with the first dose of cancer drug in the ongoing Phase 2 Ovarian Cancer Clinical Trial by July 1, 2022, then the Extension Payment will be due and payable in fully by July 30, 2022. In addition, if we fail to achieve successful completion of first Phase 2 Clinical Trial prior to December 31, 2022, and do not elect to pay the Extension Payment then Eisai may terminate the agreement in its sole discretion pursuant to the terms of the amendment. Option to Reacquire Rights to Stenoparib For the period commencing with enrollment of the first five patients in a Phase 2 clinical trial pursuant to the clinical development plan and ending 90 days following successful completion of such Phase 2 clinical trial, Eisai has the option to reacquire our licensed rights to develop stenoparib for a purchase price equal to the fair market value of our rights, giving effect to the stage of development of stenoparib that we have completed under the agreement. We commenced a Phase 2 clinical trial April 15, 2019, and as of the date of these consolidated financial statements, Eisai has not indicated an intention to exercise its repurchase option. (c) Development, Option and License Agreement with R-Pharm for IXEMPRA® On March 1, 2019, the Company entered into an option to in-license the rights to any and all therapeutic and/or diagnostic uses in humans for IXEMPRA ® (d) Development costs and Out-License Agreement with Smerud In June of 2020 (the “June 2020 Out-License Agreement”), as amended March 28, 2022 (the “Amended License Agreement”), the Company out-licensed its secondary LiPlaCis ® ® ® ® ® ® ® ® ® LiPlaCis Support Agreement with Smerud, Chosa and LiPlasome On March 28, 2022, concurrent with the entry into the Amended License Agreement, we entered into the LiPlaCis Support Agreement with Allarity Europe, Smerud, Chosa and LiPlasome (the “Support Agreement”).

Consequently, in 2022, the Company recorded a balance due to LiPlasome of $338 in accrued liabilities (paid on April 1, 2022) and recorded other income of $971, which was recognized as a gain on sale of IP. b. The LiPlacis Support Agreement between Allarity Therapeutics Europe, Smerud, Chosa and LiPlasome.

Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common shareholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common shareholders for the periods indicated because including them would have had an anti-dilutive effect: As of December 31, 2023 2022 Warrants and stock options 9,540,951 2,695,907 Series A Convertible Preferred stock 1,530,360 7,406,057 Convertible debt* — 9,071,430 11,071,311 19,173,394 * Estimated based on $2,667 at $0.1825 per share.

Financial Instruments [Abstract]
Financial Instruments	16. Financial Instruments The following tables present information about the Company’s financial instruments measured at fair value on a recurring basis and indicate the level of the fair value hierarchy used to determine such fair values: Fair Value Measurements as of December 31, 2023, Level 1 Level 2 Level 3 Total Liabilities: Warrant liability $ — $ — $ (2,263 ) $ (2,263 ) Derivative warrant liability — — (820 ) (820 ) $ — $ — $ (3,083 ) $ (3,083 ) Fair Value Measurements as of December 31, 2022, Level 1 Level 2 Level 3 Total Liabilities: Derivative warrant liability $ — $ — $ (374 ) $ (374 ) $ — $ — $ (374 ) $ (374 ) Methods used to estimate the fair values of our financial instruments, not disclosed elsewhere in these consolidated financial statements, are as follows: When available, our marketable securities are valued using quoted prices for identical instruments in active markets. If we are unable to value our marketable securities using quoted prices for identical instruments in active markets, we value our investments using broker reports that utilize quoted market prices for comparable instruments. Accordingly, our investment is considered a Level 1 financial asset. We have no financial assets or liabilities measured using Level 2 inputs. Financial assets and liabilities are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies, or similar techniques, and at least one significant model assumption or input is unobservable. The Company recognizes its derivative liabilities as level 3 and values its derivatives using the methods discussed below. While the Company believes that its valuation methods are appropriate and consistent with other market participants, it recognizes that the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. The primary assumptions that would significantly affect the fair values using terms in the notes that are subject to volatility and market price of the underlying common stock of the Company. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. The Company’s policy is to recognize transfers into and out of levels within the fair value hierarchy at the date the actual event or change in circumstances that caused the transfer occurs. When a determination is made to classify an asset or liability within Level 3, the determination is based upon the significance of the unobservable inputs to the overall fair value measurement. There were no transfers between level 1 or level 2 during the years ended December 31, 2023, or 2022. During the years ended December 31, 2023, and 2022, the Company utilized the reset strike options Type 2 model by Espen Garder Haug and Black-Scholes Merton models to measure the fair value of the 3i Exchange Warrant derivative liability at $820 and $374, respectively. All changes in fair value were recorded in the Consolidated Statements of Operation and Comprehensive Loss during the corresponding period. Fluctuations in the Company’s stock price are a primary driver for the changes in the derivative valuations during each reporting period. During the years ended December 31, 2023, and 2022, the Company’s stock price decreased from its initial valuation. As the stock price decreases for each of the related derivative instruments, the value to the holder of the instrument generally decreases. Stock price is one of the significant unobservable inputs used in the fair value measurement of each of the Company’s derivative instruments.

Pursuant to the agreement, we are solely responsible for the development of 2X-111 during the term of the agreement. Development and Sales Milestone Payments Pursuant to the agreement, we have agreed to make milestone payments to 2-BBB in connection with the development of 2X-111 by us or our affiliates, or by a third-party (a “Program Acquirer”) that assumes control of the 2X-111 development program from us corresponding to: (i) upon enrollment of the first ten patients required in a Phase 2 clinical trial; (ii) upon the successful completion of a Phase 2 clinical trial; (iii) upon dosing of the first patient in the first Phase 3 clinical trial; (iv) upon submission of the first NDA with the FDA; (v) submission of an MAA to the EMA in the European Union; (vi) upon submission of an NDA in the first of either China or India; (vii) upon receipt of the first authorization by the FDA to market and sell a licensed product; (viii) upon receipt of a MAA for a licensed product in the European Union; and (ix) upon receipt of regulatory approval in the first of either China or India.

In addition to the development milestones described above, we have agreed to make a mid-level seven figure one-time payment upon our sales of a licensed product reaching $500 million annually and a low eight figure payment upon the first and second time our sales of a licensed product reaches $1 Billion annual. If all sales milestones have been achieved, we would be obligated to pay 2-BBB up to a maximum of $22.5 million which could increase to $45 million if 2-BBB successfully expands the field of our license agreement to include all preventative, therapeutic and/or diagnostic uses related to cancer in humans. Royalty Payments In addition to the milestone payments described above, we have agreed to pay 2-BBB royalties based on annual incremental sales of product derived from 2X-111 in an amount between 5% and 10% of annual sales of between $0 and $100 million, between 6% and 13% of annual sales between $100 million and $250 million, and between 7% and 13% of annual sales in excess of $250 million. We are obligated to pay royalties under the agreement on a product-by-product and country-by-country basis, from the period of time commencing on the first commercial sale of any product in such country and expiring upon the latest of (a) the expiration of the last valid claim of a patent within (i) the 2-BBB intellectual property and/or (ii) the joint intellectual property in such country (if, but only if, such joint intellectual property arose from activities under the clinical development plan), or (b) the 10 th

Subsequent Events [Abstract]
Subsequent Events	18. Subsequent Events (a) 3i LP Securities Purchase Agreement On January 18th, 2024, we entered into a Securities Purchase Agreement with 3i, pursuant to which we issued and sold 3i a senior convertible promissory notes in an aggregate principal amount of $440 due on January 18, 2025 (the “First Note”, and together with the Purchase Agreement, the “Transaction Documents”) for an aggregate purchase price of $400, representing an approximate 10% original issue discount (the “Transaction”). We agreed to use the net proceeds from the sale of the Note for accounts payable and working capital purposes. Unless the Transaction Documents state otherwise, we may not prepay any portion of the principal amount of the Note without the Purchaser’s prior written consent. On February 13, 2024 (the “Second Closing”), the Parties entered into a Limited Waiver Agreement (the “Waiver Agreement”) and agreed that the Second Closing can be consummated prior to the 30th calendar day following January 18, 2024. The Parties further waive any rights or remedies that they may have under Section 2.3 of the Purchase Agreement, solely in connection with the Second Closing, including any rights of termination, defaults, amendment, acceleration or cancellation that be triggered under the Purchase Agreement solely as a result of accelerating the Second Closing. As of the Second Closing, we issued and sold to the Purchaser a senior convertible promissory note in an aggregate principal amount of $440 (the “Principal Amount”) due on February 13, 2025 (the “Second Note,” and together with the First Note dated January 18, 2024, and Purchase Agreement, the “Transaction Documents”) for an aggregate purchase price of $400, representing an approximately 10% original issue discount (the “Transaction”). We agreed to use the net proceeds from the sale of the Second Note for accounts payable and working capital purposes. Unless the Transaction Documents state otherwise, we may not prepay any portion of the principal amount of the Second Note without the Purchaser’s prior written consent. Subject to the satisfaction (or express waiver) of the conditions set forth in the Purchase Agreement, the Purchaser shall also have the right to require us to consummate one or more additional closings of up to an additional $600 of notes in the aggregate. Interest We agreed to pay interest to 3i on the aggregate unconverted and then outstanding principal amount of the First and Second Notes at the rate of 8% per annum. The first interest payment on the First Note is due on February 1, 2024, and has been deferred to March 1, 2024, with subsequent payments on the 1 st st Conversion of the First and Second Notes From the First Closing Date until the First Note is fully paid off, it can be converted, partially or entirely, into Common Stock at 3i’s discretion (subject to limits specified in the Note). We have committed to keeping enough of our authorized but unissued shares of Common Stock available exclusively for conversion of the Note. The set conversion price is $0.4476 per share. The number of shares to be issued upon conversion of the Note will be calculated by dividing the outstanding principal amount of the Note to be converted by $0.4476. From the Second Closing until the Second Note is fully paid off, it can be converted, partially or entirely, into Common Stock at the Purchaser’s discretion (subject to limits specified in the Second Note). We have committed to keeping enough of our authorized but unissued shares of Common Stock available exclusively for conversion of the Second Note. The set conversion price is $0.405 per share. The number of shares to be issued upon conversion of the Second Note will be calculated by dividing the outstanding principal amount of the Second Note to be converted by $0.405. 3i’s ownership percentage of our Common Stock is limited to no more than 4.99%, as determined according to Section 13(d) of the Securities Exchange Act of 1934, as amended, and its accompanying rules. Additionally, we cannot issue shares of our Common Stock in relation to the Transaction, including shares due upon the First and Second Note conversion or otherwise, that exceed 19.99% of our total outstanding shares of Common Stock, unless otherwise permitted by the Transaction documents. Redemption Subject to the provisions of the First and Second Notes, if, at any time while the First and Second Notes are outstanding, we engage in one or more subsequent financings, 3i may require us to first use up to 100% of the gross proceeds of such financing to redeem all or a portion of the First and Second Notes. However, if we raise capital in an ATM offering, 3i may request up to 20% of the proceeds to redeem the Series A Convertible Preferred Stock (the “Series A Preferred Stock”) at the stated value. Events of Default The First and Second Notes include customary event of default provisions and provide for a mandatory default provision. Upon the occurrence of an event of default, the Purchaser may require us to pay in cash the “Mandatory Default Amount” which is defined in the Note to mean the sum of (a) the greater of (i) the outstanding principal amount of the First and Second Note, plus all accrued and unpaid interest hereon, divided by the lesser of (i) 0.4476 in the case of the First Note and $0.405 in the case of the Second Note, or (ii) 85% of the average of the three lowest VWAPs during the 10 trading days ending on the trading day that is immediately prior to the applicable date the Mandatory Default Amount is either (A) demanded or otherwise due or (B) paid in full, whichever has a lower conversion price, multiplied by the highest closing price for our shares of Common Stock on the trading market during the period beginning on the date of first occurrence of the event of default and ending on the date the Mandatory Default Amount is paid in full, or (ii) 130% of the sum of the outstanding principal amount of the First and Second Note, plus accrued and unpaid interest hereon, and (b) all other amounts, costs, expenses and liquidated damages due in respect of the First and Second Note. Negative Covenants While any part of the First and Second Notes are outstanding, without prior written consent from the Purchaser and holders of at least 50.01% of the outstanding Second Note, we are restricted from (i) incurring any debt exceeding $250 in total; (ii) creating any liens on their property, except for permitted ones; (iii) making amendments to their charter documents that adversely affect the Purchaser’s rights; (iv) repurchasing our Common Stock or equivalents, except under specific conditions related to conversion shares under the Second Note and equity incentives for departing officers and directors, capped at $50 in total; (v) repurchasing or acquiring any indebtedness other than the First and Second Note, unless it is done pro-rata; (vi) paying cash dividends or distributions on their equity securities; (vii) engaging in transactions with any affiliates or related parties, unless permitted by the Purchase Agreement; and (viii) entering into agreements related to the above restrictions. Registration Rights We agreed to register with the Securities and Exchange Commission the resale of our shares of the Common Stock issuable upon conversion of the First and Second Note pursuant to the Purchase Agreement. We agreed to reimburse the Purchaser of reasonable attorneys’ fees and expenses incurred by the Purchaser for significant work in connection with the First and Second Closing. The Purchase Agreement also provides for indemnification of the Purchaser if it incurs losses, liabilities, obligations, claims, contingencies, damages, costs and expenses related to, among other things, a breach by us of any of our representations, warranties or covenants under the Purchase Agreement. (b) Series A Preferred Stock Conversions On February 8, 2024, pursuant to the exercise of conversion by the 3i, we issued 291,958 shares of Common Stock to 3i upon the conversion of 121 shares of Series A Preferred Stock based on a conversion price of $0.4476. No proceeds were received by the Company upon such conversion. As of the date of these financial statements, we had 1,296 shares of Series A Preferred Stock issued and outstanding. (c) Modification to Conversion Price of Series A Preferred Stock and 3i Exchange Warrants On January 14, 2024, pursuant to the terms of the January 14th, 2024, 3i LP Bridge Loan, the Company modified the conversion price of the 3i Exchange Warrants from $1.00 to $0.4476, thereby increasing the number of Exchange Warrants outstanding from 4,407,221 at December 31, 2023 to 9,846,339 outstanding at January 14, 2024. Also on January 14, 2024, the conversion price of the outstanding 1,417 shares of Series A Preferred Stock was revised from $1.00 to $0.4476. We filed the Fifth Certificate of Amendment to Amended and Restated Certificate of Designations of Series A Convertible Preferred Stock (the “Fifth Amendment”) with the Secretary of State of the State of Delaware to reflect the new conversion price of the Series A Preferred Stock of $0.4476. At a stated value of $1,080 for each share of Series A Preferred Stock, the revised price of $0.4476 per share results in the 1,417 shares being convertible into 3,419,035 common shares as of January 14, 2024. On February 13, 2024, pursuant to the terms of the February 13, 2024, Bridge Loan, the Company modified the conversion price of the 3i Exchange Warrants from $0.4476 to $0.4050 and thereby increased the number of Exchange Warrants outstanding from 9,846,339 on January 18, 2024, to 10,882,028 on February 13, 2024. The Company also agreed to amend the conversion price of the Series A Preferred Stock to equal $0.405 as soon as practicable. We filed the Sixth Certificate of Amendment to Amended and Restated Certificate of Designations of Series A Convertible Preferred Stock (the “Sixth Amendment”) with the Secretary of State of the State of Delaware to reflect the new conversion price of the Series A Preferred Stock of $0.405. At a stated value of $1,080 for each share of Series A Preferred Stock, the revised price of $0.405 per share results in the 1,296 shares being convertible into 3,456,000 common shares. (d) Nasdaq Hearing On February 1, 2024 we attended a de-listing appeal hearing with Nasdaq, the outcome of which is pending as of the date of this filing. (e) Settlement Agreement (with J.Cullem) As of March 7, 2024, we entered into a Settlement Agreement and General Release (“Settlement Agreement”) with James Cullem, our former CEO and director. Pursuant to the terms and conditions outlined in the Settlement Agreement and in exchange for Mr. Cullem’s commitments therein, including his general release of claims against us, among other considerations, we agreed to provide Mr. Cullem with an initial settlement payment totaling $70,000 on April 1, 2024. Additionally, we committed to making an installment payment of $179,155, divided equally into 5 monthly payments. Furthermore, we agreed to issue Mr. Cullem 290,000 settlement shares on April 1, 2024. Should the initial settlement payment and issuance of shares not be made to Mr. Cullem in full on April 1, 2024, the Settlement Agreement will be rendered null and void, releasing both parties from any further obligations under the Settlement Agreement unless otherwise mandated by a prior binding contract or agreement. Both parties will retain any and all rights, claims, and causes of action that would have otherwise been released by the Settlement Agreement. Additionally, Mr. Cullem agreed to act as our consultant and entered into a consulting agreement (the “Consulting Agreement”) with us, effective as of March 7, 2024. For the avoidance of doubt, no additional consideration is being paid to Mr. Cullem under the Consulting Agreement. Copies of the Settlement Agreement and Consulting Agreement will be included as exhibits to our Quarterly Report on Form 10-Q for the quarter ending March 31, 2024.

United States Allarity Therapeutics Europe ApS (formerly Oncology Venture Product Development ApS) Denmark Allarity Therapeutics Denmark ApS (formerly OV-SPV2 ApS) Denmark MPI Inc.* United States OV US Inc.** United States * In the process of being dissolved because inactive. ** OV US Inc. was dissolved effective November 15, 2023. All intercompany transactions and balances, including unrealized profits from intercompany sales, have been eliminated upon consolidation.
Use of Estimates	(c) Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting years. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, the fair value of the Series A preferred shares, warrants, 3i Exchange Warrants, convertible debt, and the accrual for research and development expenses, fair values of acquired intangible assets and impairment review of those assets, share based compensation expense, and income tax uncertainties and valuation allowances. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed considering reasonable changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known and if material, their effects are disclosed in the notes to the consolidated financial statements. Actual results could differ from those estimates or assumptions. (d) Foreign currency and currency translation The functional currency is the currency of the primary economic environment in which an entity’s operations are conducted. The Company and its subsidiaries operate mainly in Denmark and the United States. The functional currencies of the Company’s subsidiaries are their local currency. The Company’s reporting currency is the U.S. dollar. The Company translates the assets and liabilities of its Denmark subsidiaries into the U.S. dollar at the exchange rate in effect on the balance sheet date. Revenues and expenses are translated at the average exchange rate in effect during each monthly period. Unrealized translation gains and losses are recorded as a cumulative translation adjustment, which is included in the consolidated statements of changes in redeemable convertible preferred stock and stockholders’ equity as a component of accumulated other comprehensive loss. Monetary assets and liabilities denominated in currencies other than the functional currency are remeasured into the functional currency at rates of exchange prevailing at the balance sheet dates. Non-monetary assets and liabilities denominated in foreign currencies are re-measured into the functional currency at the exchange rates prevailing at the date of the transaction. Exchange gains or losses arising from foreign currency transactions are included in the determination of net loss for the respective periods. Adjustments that arise from exchange rate translations are included in other comprehensive income (loss) in the consolidated statements of operations and comprehensive loss as incurred. The Company recorded a foreign exchange translation gain (loss) of $309 and ($121), included in accumulated other comprehensive loss for the years ended December 31, 2023 and 2022, respectively.

Non-monetary assets and liabilities denominated in foreign currencies are re-measured into the functional currency at the exchange rates prevailing at the date of the transaction. Exchange gains or losses arising from foreign currency transactions are included in the determination of net loss for the respective periods. Adjustments that arise from exchange rate translations are included in other comprehensive income (loss) in the consolidated statements of operations and comprehensive loss as incurred. The Company recorded a foreign exchange translation gain (loss) of $309 and ($121), included in accumulated other comprehensive loss for the years ended December 31, 2023 and 2022, respectively.
Concentrations of credit risk and of significant suppliers	(e) Concentrations of credit risk and of significant suppliers Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash. The Company maintains its cash in financial institutions in amounts that could exceed government-insured limits. The Company does not believe it is subject to additional credit risks beyond those normally associated with commercial banking relationships. The Company has not experienced losses on its cash accounts and management believes, based upon the quality of the financial institutions, that the credit risk regarding these deposits is not significant. The Company is dependent on third-party manufacturers to supply products for research and development activities in its programs. In particular, the Company relies and expects to continue to rely on a small number of manufacturers to supply its requirements for supplies and raw materials related to these programs. These programs could be adversely affected by a significant interruption in these manufacturing services or the availability of raw materials.
Cash	(f) Cash Cash consists primarily of highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. The Company had no cash equivalents or restricted cash on December 31, 2023 and 2022.
Property, plant and equipment	(g) Property, plant and equipment Property, plant, and equipment are stated at cost, less accumulated depreciation. Depreciation expense is recognized using the straight-line method over the estimated useful lives of the respective assets as follows: Estimated Laboratory equipment 5 years Furniture and office equipment 3 years Upon retirement or sale, the cost of assets disposed of, and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in loss from operations. As of December 31, 2023 and 2022, there have been no significant asset retirements to date. Expenditures for repairs and maintenance that do not improve or extend the lives of the respective assets are charged to expense as incurred.
Impairment of long-lived assets	(h) Impairment of long-lived assets Long-lived assets consist of property, plant and equipment, and intangible assets. Long-lived assets to be held and used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations, significant negative industry or economic trends and significant changes or planned changes in the use of the assets. An impairment loss would be recognized as a loss from operations when estimated undiscounted future cash flows expected to result from the use of an asset group or the estimated return on investment are less than its carrying amount. The impairment loss would be based on the excess of the carrying value of the impaired asset group over its fair value, determined based on discounted cash flow or return on investment calculations.
Acquired patents	(i) Acquired patents Acquired patents are measured in the balance sheet at the lower of cost less accumulated amortization and impairment charges, if any. The legal costs incurred to renew or extend the term of the acquired patents are expensed as incurred. Cost comprises the acquisition price and the depreciation period are estimated at approximately 5 years with no residual value. Depreciation methods, useful lives and residual values are reviewed every year.
Acquired in-process research and development (IPR&D)	(j) Acquired in-process research and development (IPR&D) Acquired IPR&D represents the fair value assigned to research and development assets that the Company acquired as part of a business combination and have not been completed at the acquisition date. The fair value of IPR&D acquired in a business combination is recorded on the consolidated balance sheets at the acquisition-date fair value and is determined by estimating the costs to develop the technology into commercially viable products, estimating the resulting revenue from the projects, and discounting the projected net cash flows to present value. IPR&D is not amortized, but rather is reviewed for impairment on an annual basis or more frequently if indicators of impairment are present, until the project is completed, abandoned, or transferred to a third-party. Management assesses its acquired IPR&D for impairment at year end date as well as when events and circumstances indicate there is a potential impairment. Significant quantitative indicators considered are the Company’s market capitalization, market share, length of remaining clinical trials, and projected revenue per treatment. The projected discounted cash flow models used to estimate the fair value of partnered assets and cost approach model used to estimate proprietary assets as part of the Company’s IPR&D reflect significant assumptions regarding the estimates a market participant would make to evaluate a drug development asset, including the following: ● Estimates of obsolescence of development expenditure; ● Probability of successfully completing clinical trials and obtaining regulatory approval; ● Estimates of future cash flows from potential milestone payments and royalties related to out-licensed product sales; and ● A discount rate reflecting the Company’s weighted average cost of capital and specific risk inherent in the underlying assets. Once brought into use, intangible assets are amortized over their estimated useful economic lives using the economic consumption method if anticipated future revenues can be reasonably estimated. The straight-line method is used when revenues cannot be reasonably estimated. In the years ended December 31, 2023 and 2022, the Company has recorded impairment losses of $0 and $17,571 respectively on its intangible assets.
Fair value measurements of financial instruments	(k) Fair value measurements of financial instruments The carrying value of the Company’s financial instruments of cash, other current assets, accounts payable and accrued liabilities, approximate their fair value due to their short-term nature. The Company’s other financial instruments include an equity investment, preferred shares, convertible debt, and warrant derivative liabilities. The equity investment is adjusted to fair market value at the end of every period based upon unadjusted quoted prices. The convertible debt and derivative liabilities that are freestanding equity-linked financial instruments are fair valued at the end of every period using level 3 inputs. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC Topic 820, Fair Value Measurement (“ASC 820”), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. ASC 820 identifies fair value as the exchange price, or 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 a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tier fair value hierarchy that distinguishes between the following: ● Level 1 — defined as observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. ● Level 2 — defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and ● Level 3 — defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.
Segment and geographic information	(l) Segment and geographic information Operating segments are defined as components of a business for which separate discrete financial information is available for evaluation by the chief operating decision maker in deciding how to allocate resources and assess performance. The Company and its chief operating decision maker, the Company’s Chief Executive Officer, view the Company’s operations and manage its business as a single operating segment. The Company operates in two geographic areas: Denmark and the United States.
Research contract costs and accruals	(m) Research contract costs and accruals Research and development costs are expensed as incurred. Research and development expenses are comprised of costs incurred in performing research and development activities, including salaries, share-based compensation and benefits, facilities costs and laboratory supplies, depreciation, amortization and impairment expense, manufacturing expenses and external costs of outside vendors engaged to conduct preclinical development activities and clinical trials. Typically, upfront payments and milestone payments made for the licensing of technology are expensed as research and development in the period in which they are incurred. The Company has entered into various research and development contracts with companies in Europe, the United States, and other countries. These agreements are generally cancellable, and related payments are recorded as research and development expenses as incurred. The Company records accruals for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies or trials, including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. The Company’s historical accrual estimates have not been materially different from the actual costs.
Research and development incentives and receivable	(n) Research and development incentives and receivable Denmark Tax Incentives Denmark allows loss making companies the opportunity to apply for a payment equal to the tax value (22%) of negative taxable income related to R&D costs. The negative taxable income is calculated on the total negative income of the companies participating in the joint taxation. Tax payment according to this rule cannot exceed an amount of DKK 5.5 million, corresponding to a tax loss relating to R&D expenditure of DKK 25 million. The tax credit is recorded as tax receivable and other income within research and development expenses. In the years ended December 31, 2023 and 2022, the Company recorded $800 and $711 in tax credits, respectively, thereby reducing research and development expenses. European Agency Grants The Company, through its subsidiaries in Denmark, from time-to-time receives reimbursements of certain research and development expenditures as part of a European agency’s research and development cost relief program. Management has assessed the Company’s research and development activities and expenditures to determine which activities and expenditures are likely to be eligible under the research and development incentive program described above. At each period end, management estimates the reimbursement available to the Company based on available information at the time. The Company records these research and development expense reimbursements as a reduction to research and development expenses in the consolidated statements of operations and comprehensive loss, as the research and development cost reimbursements are not dependent on the Company generating future taxable income, the Company’s ongoing tax status, or tax position. The Company recognizes a receivable for the research and development incentives when the relevant expenditure has been incurred, the associated conditions have been satisfied and there is reasonable assurance that the reimbursement will be received. During the years ended December 31, 2023 and 2022, the Company has not received or recorded government grants receivable.
Convertible debt instruments	(o) Convertible debt instruments The Company follows ASC 480-10, Distinguishing Liabilities from Equity Additionally, the Company accounts for certain convertible debt (“Convertible Notes”) issued under the fair value option election of ASC 825, Financial Instruments wherein the financial instrument is initially measured at its issue-date estimated fair value and then subsequently re-measured at estimated fair value on a recurring basis at each reporting period date. The estimated fair value adjustment is recognized as other income (expense) in the accompanying consolidated statements of operations and the portion of the fair value adjustment attributed to a change in the instrument-specific credit risk is recognized as a component of other comprehensive loss. Convertible Notes are settled with shares at fair value of the stock issued with any differences recorded to other income (expense), as a gain (loss) on extinguishment.
Warrants	(p) Warrants When the Company issues warrants it evaluates the proper balance sheet classification to determine classification as either equity or as a derivative liability on the consolidated balance sheets. In accordance with ASC 815-40, Derivatives and Hedging-Contracts in the Entity’s Own Equity (“ASC 815-40”), the Company classifies a warrant as equity so long as it is “indexed to the Company’s equity” and several specific conditions for equity classification are met. A warrant is not considered indexed to the Company’s equity, in general, when it contains certain types of exercise contingencies or adjustments to exercise price. If a warrant is not indexed to the Company’s equity or it has net cash settlement that results in the warrants to be accounted for under ASC 480, Distinguishing Liabilities from Equity, or ASC 815-40, it is classified as a derivative liability, which is carried on the Consolidated Balance Sheet at fair value with any changes in its fair value recognized immediately in the Consolidated Statement of Operations and Comprehensive Loss. As of December 31, 2023 and 2022, the Company had warrants outstanding for share-based compensation that were classified as equity, and outstanding investor warrants that were classified as derivative liabilities and classified as “Warrant liabilities” in the Consolidated Balance Sheets.
Derivative financial instruments	(q) Derivative financial instruments The Company does not use derivative instruments to hedge exposures to interest rate, market, or foreign currency risks. The Company evaluates all its financial instruments to determine if such instruments contain features that qualify as embedded derivatives. Embedded derivatives must be separately measured from the host contract if all the requirements for bifurcation are met. The assessment of the conditions surrounding the bifurcation of embedded derivatives depends on the nature of the host contract. Bifurcated embedded derivatives are recognized at fair value, with changes in fair value recognized in the Consolidated Statements of Operations and Comprehensive Loss each reporting period.
Share-based compensation	(s) Share-based compensation The Company accounts for share-based compensation in accordance with ASC 718, Compensation — Stock Compensation (“ASC 718”). ASC 718 requires companies to estimate the fair value of equity-based payment awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service period in the Company’s Consolidated Statements of Operations and Comprehensive Loss. The Company records the expense for option awards using either a graded or straight-line method. The Company accounts for forfeitures as they occur. For share-based awards granted to both employee and non-employee consultants, the measurement date for non-employee awards is the date of grant. The compensation expense is then recognized over the requisite service period, which is the vesting period of the respective award. The Company reviews all stock award modifications including when there is an exchange of original award for a new award. In the case of stock award modifications, the Company calculates for the incremental fair value based on the difference between the fair value of the modified award and the fair value of the original award immediately before it was modified. The Company immediately recognizes the incremental value as compensation cost for vested awards and recognizes, on a prospective basis over the remaining requisite service period, the sum of the incremental compensation cost and any remaining unrecognized compensation cost for the original award on the modification date. The fair value of stock options (“options”) on the grant date is estimated using the Black-Scholes option-pricing model using the single-option approach. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions, including the option’s expected term and the price volatility of the underlying stock, to determine the fair value of the award. The Company applies the Black-Scholes model as it believes it is the most appropriate fair value method for all option awards. The Black-Scholes model requires several assumptions, of which the most significant are the share price, expected volatility and the expected award term. Expected term of options granted is calculated using the simplified method being the average between the vesting period and the contractual term to the expected term of the options in effect at the time of grant. The Company has historically not paid dividends and has no foreseeable plans to pay dividends and, therefore, uses an expected dividend yield of zero in the option pricing model. The risk-free interest rate is based on the yield of U.S. treasury bonds with equivalent terms. The Company classifies share-based compensation expense in its Consolidated Statements of Operations and Comprehensive Loss in the same way the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.
Accumulated other comprehensive loss	(t) Accumulated other comprehensive loss Accumulated other comprehensive loss includes net loss as well as other changes in stockholders’ equity (deficit) that result from transactions and economic events other than those with shareholders. The Company records unrealized gains and losses related to foreign currency translation and instrument specific credit risk as components of other accumulated comprehensive loss in the Consolidated Statements of Operations and Comprehensive Loss. For the years ended December 31, 2023 and 2022, the Company’s other comprehensive loss was comprised of currency translation adjustments and fair value adjustments attributable to instrument specific credit risk.
Contingencies	(u) Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. At each reporting date, the Company evaluates whether a potential loss amount or a potential loss range is probable and reasonably estimable under the provisions of the authoritative guidelines that address accounting for contingencies. The Company expenses costs as incurred in relation to such legal proceedings as general and administrative expense within the Consolidated Statements of Operations and Comprehensive Loss.
Income taxes	(v) Income taxes The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the consolidated financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined based on the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies. The Company accounts for uncertainty the consolidated financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not-to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the consolidated financial statements. The amount of the benefit that may be recognized is the largest amount that will more likely than not be realized upon ultimate settlement. Any provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits that are considered appropriate. The Company recognizes interest and penalties related to uncertain tax positions in other (income) expenses.
Computation of loss per share	(w) Computation of loss per share Basic net loss per common share is determined by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration of common stock equivalents. Diluted net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common stock and common stock equivalents outstanding for the period. The Company adjusts net loss to arrive at the net loss attributable to common stockholders to reflect the amount of dividends accumulated during the period on the Company’s redeemable convertible preferred stock, if any. The treasury stock method is used to determine the dilutive effect of the Company’s stock option grants and warrants and the if-converted method is used to determine the dilutive effect of the Company’s redeemable convertible preferred stock and Convertible Notes. For the years ended December 31, 2023 and 2022, the Company had a net loss attributable to common stockholders, and as such, all outstanding stock options, shares of redeemable convertible preferred stock, and warrants were excluded from the calculation of diluted loss per share. Under the if-converted method, convertible instruments that are in the money, are assumed to have been converted as of the beginning of the period or when issued, if later.
Recently Issued Accounting Pronouncements	(x) Recently issued accounting pronouncements Changes to GAAP are established by the FASB in the form of ASUs to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. All other ASUs issued through the date of these financial statements were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s consolidated financial position and results of operations.
