Accounting Policies [Abstract]
Nature of Business and Summary of Significant Accounting Policies	1. Nature of Business and Summary of Significant Accounting Policies (a) Reorganization Effective December 20, 2021, and in connection with the Plan of Reorganization and Asset Purchase Agreement which was amended and restated on September 23, 2021, between Allarity Therapeutics, Inc. a Delaware corporation (the “Company”), Allarity Acquisition Subsidiary Inc., the Company’s wholly owned Delaware subsidiary (“Acquisition Sub”), and Allarity Therapeutics A/S, an Aktieselskab organized under the laws of Denmark (“Allarity A/S”), the Company completed an Asset Purchase Agreement with Acquisition Sub and Allarity A/S pursuant to which Allarity A/S sold, and Acquisition Sub purchased, all of Allarity A/S’ assets and certain specified liabilities in connection with Allarity A/S’ business for an aggregate purchase price of 8,075,824 shares of the Company’s common stock plus the assumption of specified liabilities. Thereafter, Allarity A/S is in the process of being dissolved and liquidated in accordance with Part 14 of Danish Companies Act. While Allarity Therapeutics, Inc. was the legal acquirer of Allarity Therapeutics A/S, for accounting purposes, the Merger is treated similarly to a reverse recapitalization, whereby Allarity Therapeutics A/S is deemed to be the accounting acquirer, and the historical financial statements of Allarity Therapeutics A/S became the historical financial statements of Allarity Therapeutics, Inc. upon the closing of the reorganization. Under this method of accounting, Allarity Therapeutics, Inc. was treated as the “acquired” company and Allarity Therapeutics A/S is treated as the acquirer for financial accounting purposes. Accordingly, for accounting purposes, the reorganization was treated as the equivalent of Allarity Therapeutics A/S issuing stock for the net assets of Allarity Therapeutics, Inc. accompanied by a recapitalization. Because the reorganization is a common control transaction the net assets and prior year financial statements were stated at historical cost, with no goodwill or other intangible assets recorded. In accordance with ASC 805, the legal capital of Allarity Therapeutics A/S has been retroactively adjusted to reflect the capital of the legal acquirer (accounting acquiree) Allarity Therapeutics, Inc. (b) Principal Operations and Activities The Company’s principal operations are located at Venlighedsvej 1, 2970 Horsholm, Denmark. The Company’s United States operations are located at 210 Broadway #201, Cambridge, MA 012139, United States of America. The Company develops drugs for the personalized treatment of cancer using drug specific companion diagnostics (cDx) generated by its proprietary drug response predictor technology, DRP ® (c) 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 financial statements do not reflect any adjustments relating to the recoverability and reclassifications 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 management’s evaluation under the requirements of Accounting Standard Codification (ASC) 205-40. Since inception, the Company has devoted substantially all of 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 $49.7 million and $39.8 million as of September 30, 2021 and December 31, 2020 respectively. As of August 20, 2021, the issuance date of the financial statements for the year ended December 31, 2020, our cash which included the proceeds of our rights offering in June 2021 was insufficient to fund our current operating plan and planned capital expenditures for at least the next 12 months. As of May 16, 2022, our cash is insufficient to fund our current operating plan and planned capital expenditures for the next 12 months. These conditions give rise to a 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. 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 into 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. The Company entered into a Securities Purchase Agreement with the holder of all of the Company’s Series A Preferred Stock (the “Investor”) that provides for a $20 million equity investment in the Company. Please refer to the subsequent event disclosures in note 19 for further information. 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. Further, at the date of this filing the above noted Investor $20 million equity investment cannot be asserted as probable and is subject to close of the transaction. 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. (d) Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”). The accompanying interim condensed consolidated financial statements as of September 30, 2021, and for the three and nine months ended September 30, 2021 and 2020, and related interim information contained within the notes to the financial statements, are unaudited. In management’s opinion, the unaudited interim condensed consolidated financial statements have been prepared on the same basis as the Company’s audited financial statements and include all adjustments (including normal recurring adjustments) necessary for a fair statement of the financial statements. The condensed consolidated balance sheet at December 31, 2020, was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and accompanying notes included in its Form S-4 for the year ended December 31, 2020, filed on August 20, 2021, and as amended. The results for the three and nine months ended September 30, 2021, are not necessarily indicative of the results expected for the full fiscal year or any interim period. As a result of the recapitalization share exchange (also described in Note 1), to these financial statements, all outstanding shares, warrants, and options were exchanged on a 50:1 basis as of December 20, 2021, and accordingly, all share, warrant, option and per share disclosure in these financial statements has been retroactively adjusted to reflect the 50:1 reverse split unless otherwise stated. (e) 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 Oncology Venture US Inc. United States All intercompany transactions and balances, including unrealized profits from intercompany sales, have been eliminated upon consolidation. (f) Use of Estimates The preparation of 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 convertible loan, the accrual for research and development expenses, revenue recognition, fair values of acquired intangible assets and impairment review of those assets, the useful life of property, plant and equipment, share based compensation expense, provisions for contingencies and litigation, 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 in light of 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. (g) Computation of Earnings (Loss) per Share The Company computes net (loss) income per share in accordance with ASC Topic 260, “Earnings Per Share” (“ASC 260”) and related guidance, which requires two calculations of net (loss) income attributable to the Company’s shareholders per share to be disclosed: basic and diluted. Basic loss per share is derived by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during each period. Diluted loss per share includes the effect, if any, from the potential exercise or conversion of securities, such as warrants, and convertible debt, which would result in the issuance of incremental shares of common stock unless such effect is anti-dilutive. In calculating the basic and diluted net loss per share applicable to common stockholders, the weighted average number of shares remained the same for both calculations since when a net loss exists, dilutive shares are not included in the calculation. (h) Conversion of foreign currencies 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 shareholders’ equity as a component of accumulated other comprehensive (loss) income. Monetary assets and liabilities denominated in currencies other than the functional currency are re-measured 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 profit or loss for the respective periods. Adjustments that arise from exchange rate changes on transactions denominated in a currency other than the local currency are included in other comprehensive income (loss) in the consolidated statements of operations and comprehensive loss as incurred. (i) Accumulated other comprehensive income (loss) Accumulated other comprehensive income (loss) includes all changes in equity except those resulting from investments by owners and distributions to owners, including accumulated foreign currency translation, and changes in instrument specific credit risk. During the three months ended September 30, 2021, and 2020 the Company recorded accumulated foreign currency translation losses of ($939) and gains of $1,130 respectively. During the nine months ended September 30, 2021, and 2020 the Company recorded accumulated foreign currency translation losses of ($1,785) and gains of $1,212 and instrument specific credit risk losses of ($9) and gains of $6 respectively. These amounts have been recorded as a separate component of stockholders’ equity (deficit). (j) 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. (k) JOBS Act accounting election The Company is an “emerging growth company”, as defined in the Jumpstart Our Business Startups Act of 2012 (JOBS Act). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies; however, the Company may adopt new or revised accounting standards early if the standard allows for early adoption. (l) Recently Issued Accounting Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (the “FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. ASUs not listed below 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. Adopted In December 2019, the FASB issued ASU 2019-12, “Income Taxes — Simplifying the Accounting for Income Taxes”. The ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles as well as clarifying and amending existing guidance to improve consistent application. The amendments to this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. Depending on the amendment, adoption may be applied on the retrospective, modified retrospective or prospective basis. The Company has adopted this standard on a prospective basis with no significant impact upon its consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. ASU No. 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. ASU No. 2020-06 is effective for public companies for annual periods beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted for annual periods beginning after December 15, 2020, and interim periods within those fiscal years. The Company has early adopted this standard effective January 1, 2021 on a modified retrospective basis with no significant impact on its consolidated financial statements. Not Yet Adopted In May 2021, the FASB issued ASU No. 2021-04 — Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options — to clarify the accounting by issuers for modifications or exchanges of equity-classified warrants. The framework applies to freestanding written call options, such as warrants, that were and remain equity classified by the issuer after the modification and are not in the scope of another Codification Topic. The framework applies regardless of whether the modification is through an amendment to the existing terms or issuance of a replacement warrant. The effect of the modification of the warrant is measured as the difference in its fair value immediately before and after the modification. The effect is recognized in the same manner as if cash had been paid as consideration. Additionally, other modifications may need to be accounted for as a cost to the issuing entity based on the substance of the transaction. The Update is effective prospectively for fiscal years beginning after December 15, 2021, including interim periods therein, with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

Restatement Of Previously Issued Financial Statements [Abstract]
Restatement of Previously Issued Financial Statements	2. Restatement of Previously Issued Financial Statements (a) Restatement for Investor Warrants in September 30, 2021 Financial Statements At the time of issuance of the TO3 Warrants on June 24, 2021, a Black-Scholes model was used, and a value of $5,151 was calculated using the following factors: share price SEK .92; exercise price SEK 1.70; historical and expected volatility 104.20%; option life 24 months, expected dividends 0%; and risk-free interest rate -.50% however certain market conditions were not considered. After the issuance of the Company’s September 30, 2021, financial statements on November 23, 2021, management corrected its valuation method to incorporate Monte Carlo simulations under different market conditions, as scheduled below, resulting in a probability weighted value of the TO3 warrants of $2,000 and $2,100 at June 24, 2021 and June 30, 2021 respectively. And warrants exercised on September 13, 2021, were re-valued at $206 using a Black-Scholes model with the assumptions noted below. June 24, June 30, September 13, Exercise price $ 10.05 $ 9.95 $ 9.86 Stock price $ 5.50 $ 6.3 $ 10.61 Risk-free interest (0.55 )% (0.56 )% (0.50 )% Expected dividend yield (0 )% (0 )% (0 )% Contractual life (years) 1.81 1.79 0.04 Expected volatility 106.5 % 98 % 104 % The restatement relates to the accounting for the derivative liability, a correction to allocate $393 of offering costs from equity to finance expense, and a reduction in value of the exercised warrants from $483 to $206. Based upon the above, values attributed to the derivative liability, the change in value of the derivative liability, interest costs, and foreign exchange have been adjusted in the following tables for each of the periods presented below: (b) Restatement of previously issued Unaudited Quarterly report for the period ended September 30, 2021 and September 30, 2020 The Company has restated its financial statements as of and for the three and nine month periods ended September 30, 2021 and September 30, 2020, to correct the following errors: a) The Company identified a convertible promissory note that was previously unrecorded. The Company assumed this promissory note as part of the 2018 acquisition of Oncology Venture Product Development ApS (the “2018 Merger”). This promissory note (the “Note”) should have been recorded at fair value at the date of acquisition and accreted over time to its face value. To correct this error, the Company has made adjustments before tax to: 1) record the cumulative impact of accrued interest, accretion of the discount and a reduction of the bargain purchase gain booked at the time of the acquisition on accumulated losses of $699, as an adjustment to the January 1, 2019 opening balance of accumulated losses on the statement of equity, 2) record an $88 adjustment to the January 1, 2020 opening balance of accumulated losses on the statement of equity to reflect accrued interest for the year ended December 31, 2019, 3) record the amortized cost of the Note of $954 and $856 as a non-current liability as of September 30, 2021 and 2020, respectively, and 4) record the interest and accretion for the three months ended September 30, 2021 and 2020 of $27 and $24, respectively; and by $74 and $69 for the nine months ended September 30, 2021 and 2020, respectively. The restatement tax effect of the Note is included in b) below. b) The Company identified an error in the valuation allowance relating to its deferred tax assets as of September 30, 2021 and 2020, and the income tax provision for the periods ended September 30, 2021, and 2020. In determining the valuation allowance in the previously issued financial statements, the Company assumed a reversal time frame for its most significant deferred tax liability related to IPR&D that was inconsistent with the classification of the IPR&D as indefinite-lived intangible assets. Consequently, an additional valuation allowance of $1,876 and $1,806 is necessary as of September 30, 2021 and 2020, respectively. To correct this error, the Company made adjustments to 1) record the cumulative impact of $81 as of January 1, 2020 as an increase in accumulated losses; 2) increase the valuation allowance as of September 30, 2021 and 2020 by $1,876 and $1,806, respectively, and 3) reduce the tax benefit for the three months ended September 30, 2021 and 2020 by $163 and $602 respectively; and by $468 and $1,806 for the nine months ended September 30, 2021 and 2020 respectively. c) The Company corrected certain classification matters related to the presentation of extinguishment of debt. In addition, the tax credit of $219 and $227 for the three months ended September 30, 2021 and 2020 respectively; and $656 and $681 for the nine months ended September 30, 2021 and 2020 respectively, was presented as a tax benefit in the income tax provision line. However, since it is not dependent on the generation of taxable income the presentation has been corrected to reflect the tax credit as a reduction of research and development expenses in the statement of operations. i.

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 (f/k/a OV-SPV2 ApS). All other provisions of the Original Agreement and Promissory Note were unchanged and remain in full force and effect. Prior to the 2018 Merger, on April 6, 2018 (“Effective Date”), Allarity Europe and Novartis entered a license agreement whereby Novartis granted to Allarity Europe (a) an exclusive, royalty-bearing, sublicensable, assignable license under the Licensed Data (as defined in the License Agreement) and Product-Specific Patents (as defined in the License Agreement) and (b) a non-exclusive, royalty-bearing, sublicensable, assignable license under the Platform Patents (as defined in the License Agreement), in the case of (a) and (b) solely to develop and otherwise commercialize the Licensed Product (as defined in the License Agreement) in any and all field related to therapeutic and/or diagnostic uses related to cancer in humans worldwide and to manufacture the compound TKI258 (a.k.a. Dovitinib) for use in a Licensed Product as of the Effective Date. In consideration of the licenses and rights granted, Allarity Europe paid Novartis a one-time, non-refundable, non-creditable upfront payment consisting of $1,000 (“Upfront Payment”) and issued to Novartis a Promissory Note with an initial principal balance equal to $1,000, which Allarity Europe caused its affiliate, OV-SPV2, to issue to Novartis. In accordance with the terms of the Promissory Note, all payments shall be applied first to accrued interest, and thereafter to principal. The outstanding principal amount of the Note, plus any accrued interest thereon, shall be due and payable on the earlier to occur of: (i) the seventh (7th) anniversary of April 6, 2018; and (ii) an event of default (the “Maturity Date”). 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 five percent (5%) per annum. Interest shall be calculated on the basis of a 360-day year for the actual number of days elapsed. The entire outstanding principal balance of the Promissory Note and all accrued interest shall be fully due and payable on the Maturity Date. The Promissory Note is convertible upon an initial public offering (“IPO”) of OV-SPV2 and allows Novartis a one-time right to exchange the Convertible Promissory Note for such number of equity securities of OV-SPV2 equal to three percent (3%) of OV-SPV2’ outstanding equity securities, calculated on a fully diluted as-converted to common stock basis, held by all holders of equity securities of OV-SPV2 immediately prior to the closing of the IPO. As the Promissory Note was assumed in connection with the 2018 Merger, the Company recognized the Promissory Note and related accrued interest at its fair value. The Company utilized a third-party valuation specialist to estimate the fair value of the Promissory Note and related accrued interest. Based on the specialist’s valuation, the Company recognized the Promissory Note and related accrued interest at its estimated fair value, based upon an equivalent market interest rate of 12.875%, of approximately $645 on the issuance date in August 2018. The amortization rate of 11.75% resulted in an amortized value of $787 at December 31, 2019 and we recognized interest expense of $24 and $23 in the three months ended September 30, 2021 and 2020 respectively and $74 and $69 in the nine months ended September 30, 2021 and 2020 respectively. The Company will not measure the Note at fair value in subsequent reporting periods. The Company evaluated the Promissory Note under ASC 480 and the identified embedded features to determine if bifurcation is required pursuant to ASC 815-15-25-1. The Promissory Note is considered to be a freestanding instrument that is convertible into shares of the OV-SPV2 ApS’ common (or preferred, as the case may be) equity. The Promissory Note was not issued in conjunction with any other instrument meaning that the Promissory Note meets the definition of a freestanding instrument. Since the conversion feature meets the definition of a derivative it was evaluated for bifurcation and management determined the conversion feature does not require bifurcation at this time. The Company will continue to monitor for changes in specific facts and circumstances which may impact the conclusions reached herein. During the three and nine month period ended September 30, 2021, the Company recorded $24 and $74 respectively to interest expense and increased the convertible promissory note liability by the same amount. The roll forward of the Promissory Notes as of September 30, 2021, and December 31, 2020, is as follows: September 30, December 31, Convertible promissory note 1,000 1,000 Less debt discount, opening (263 ) (306 ) Plus, accretion of debt, discount, interest expense 36 43 Convertible promissory note, net of discount 773 737 Interest accretion, opening 143 92 Interest accretion, expense 38 51 Ending balance 954 880

Debt Disclosure [Abstract]
Convertible debt	12. Convertible debt On March 31, 2020 the Company entered into an agreement to issue up to $10,100 (SEK 100,000) (the “Commitment”) to be funded in tranches (“Tranches”) of ten non-interest-bearing notes (“Notes”) convertible into new shares of the Company, each with a value of $1,010 (SEK 10,000); 95% of each Tranche is received in cash, net of a 5% fee, and the conversion price of the Notes is 95% of the lowest closing volume weighted average price as reported by Bloomberg (“VWAP”). The Company accounted for the Notes issued under the FVO election whereby the financial instrument is initially measured at its issue-date estimated fair value and subsequently re-measured at estimated fair value on a recurring basis at each reporting date. The estimated fair value adjustment is presented as a single line item within other income (expense) in the accompanying consolidated statements of operations under the caption “change in fair value of convertible notes and derivative liabilities. We determined the fair value of the Notes using a discounted cash flow valuation technique with a weighted average cost of capital of 15%. The Company estimates the change in fair value attributable to the instrument specific credit risk of the Notes at 1% under the fair value option and accordingly has recognized a loss of $Nil and $9 in other comprehensive income during the three and nine-month periods ended September 30, 2021 (2020: $Nil). The roll forward of the Notes as of September 30, 2021, and December 31, 2020 is as follows: September 30, December 31, (Restated) Opening fair value 1,327 — Convertible debt issued in the period 1,024 3,416 Change in fair value (loss) reported in statement operations 474 573 Conversion of notes to common shares (2,825 ) (2,662 ) Ending fair value balance — 1,327 An effective interest rate determines the fair value of the Notes. The notes are unlisted and therefore, they are categorized as Level 3 in accordance with ASC 820, “Fair Value Measurements and Disclosures.” The notes were fully converted to shares during the period ended June 30, 2021. The estimated fair value of the net carrying amount of liability component of the Notes as of September 30, 2021, and December 31, 2020, was $Nil and $1,327 respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Liabilities	12. Derivative Liabilities (a) Investor Warrants The exercise price of our investor warrants described below is denominated in SEK; however, the functional currency of the Company is DKK. Consequently, the value of the proceeds on exercise is not fixed and will vary based on foreign exchange rate movements. The investor warrants when issued other than as compensation for goods and services are therefore a derivative for accounting purposes and are required to be recognized as a derivative liability and measured at fair value at each reporting period. Any changes in fair value from period to period are recorded as non-cash gain or loss in the consolidated statements of comprehensive loss. Upon exercise, the holders will pay the Company the respective exercise price for each investor warrant exercised in exchange for one common share of the Company and the fair value at the date of exercise and the associated non-cash liability will be reclassified to share capital. The non-cash liability associated with any investor warrants that expire unexercised will be recorded as a gain in the consolidated statements of comprehensive loss. There are no circumstances in which the Company would be required to pay any cash upon exercise or expiry of the investor warrants. In connection with subscriptions of Offer Units in the rights issue carried out April/May 2019, 403,324 investor warrants (“TO1 warrants”) have been granted to investors. All Warrants were vested as per the grant date. A warrant gives the right, during a fixed period to subscribe for one common share in the Company at $45. All TO1 warrants expired unexercised in the period ended December 31, 2020. In connection with subscriptions of Offer Units in the rights issue carried out October — December 2019, 1,006,822 investor warrants (“TO2 warrants”) have been granted to investors. All Warrants were vested as per the grant date. A warrant gives the right, during a fixed period to subscribe for one common share in the Company at $34.5. The final exercise period for the warrants of series TO 2 took place from September 1 up to and including September 15, 2021. Any TO 2 warrants unexercised after September 13, 2021, expired without compensation or payment of any kind to the warrant holders. During the three-month period ended September 30, 2021, a total of 8,820 warrants of series TO 2 were exercised for subscription of 176 shares for total proceeds of $6. In connection with subscriptions of Offer Units in the rights issue carried out in June 2021, 2,417,824 investor warrants (“TO3 warrants”) were granted to investors and 482,250 TO3 warrants were granted to underwriters. All Warrants were vested as of the grant date. In accordance with the terms of the Company’s outstanding TO3 Warrants, on August 26, 2021, the Company’s Board of Directors set an extraordinary and final exercise period for the Company’s TO3 Warrants, starting on August 30, 2021, and ending on September 13, 2021. Any TO3 warrants unexercised after September 13, 2021, expired without compensation or payment of any kind to the warrant holders. During the period ended September 30, 2021, 274,386 warrants of series TO3 were exercised for total proceeds of $2,679 and the balance expired unexercised on September 13, 2021. The table below summarizes the number of investor warrants that were outstanding, their weighted average exercise price (“WAEP”) as at September 30, 2021 and December 31, 2020, as well as the movements during the respective periods: Nine months ended Year ended Number Weighted Number Weighted Outstanding, opening 1,086,759 $ 36.0 1,410,146 $ 35.0 Granted 2,900,074 $ 10.0 79,937 $ 18.0 Exercised (274,562 ) $ 10.0 — — Expired (3,632,334 ) $ 17.0 (403,324 ) $ 41.0 Outstanding, ending 79,937 $ 18.0 1,086,759 $ 36.0 Exercisable, ending 79,937 $ 18.0 1,086,759 $ 36.0 (b) Financing Facility Effective November 29, 2018 the Company established a convertible debt facility (the “Facility”) for funding of up to SEK 200 million to be funded in up to 20 tranches of SEK 10 million each over a 24 month term and bearing interest at 2% per annum. Five of the tranches were receivable under the Facility at the discretion of the investor and the Facility was convertible into shares and warrants at 50% of the nominal amount of the notes. The Company has evaluated the terms of the Financing Facility in accordance with ASC 815-40-15 and ASC 815-40-25 and determined that the instrument is a derivative. Accordingly, the accounting treatment is the same as that described in Note 12(a) above. On June 3, 2019, the Company settled one of the five tranches and in February 2020 the balance of the committed tranches were settled by receipt of $1 million (SEK 10,5 million) from the investor in cash, in exchange for a subscription of 186,600 common shares in the Company (Settlement Shares) valued at $2,500 and the issuance of 79,937 investor warrants at an exercise price of $18 each (Settlement Warrants) valued at $0.6 million as of the February 23, 2020 grant date. All Settlement Warrants immediately vested on the grant date, were exercisable at $20 per common share and expired unexercised as of December 12, 2021. As at September 30, 2021, the weighted average contractual life of all of the investor warrants described in this Note 12 (a) and (b) is 1.40 years. The weighted average exercise price for the warrants as at the end of September 30, 2021, is $19 each.

Earnings Per Share [Abstract]
Basic and diluted net loss per share	16. Basic and diluted net loss per share Basic net income loss per share is computed based on the weighted average number of ordinary shares outstanding during each period. Diluted net income per share is computed based on the weighted average number of ordinary shares outstanding during the period plus potential shares (deriving from warrants and convertible notes) considered outstanding during the period, in accordance with ASC 260-10 as determined under the treasury stock method.

In the three-month period ended September 30, 2020 and the nine month periods ended September 30, 2021 and 2020, the Company’s unvested restricted shares and restricted share units have been excluded from the computation of basic net loss per share attributable to common shareholders. The Company’s potentially dilutive securities, which include warrants and shares issuable upon conversion of convertible debt, have been excluded from the computation of diluted net loss per share attributable to common shareholders as the effect would be to reduce the net loss per share attributable to common shareholders. 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: Three month period ended Nine month period ended 2021 2020 2021 2020 Warrants 190,970 174,345 215,119 174,345

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 nine months ended September 30, 2021, and the year ended December 31, 2020.

Subsequent Events For its interim consolidated financial statements as of September 30, 2021, and for the nine months then ended, the Company evaluated subsequent events through the date on which those financial statements were issued. (a) Subsequent events as of November 23, 2021, as reported at the initial filing date of September 30, 2021 10-Q i. Plan of Reorganization and US Nasdaq Listing On April 6, 2021, the Company incorporated Allarity Therapeutics, Inc., a Delaware corporation, (“Allarity Delaware”) as a direct wholly owned subsidiary of the Company for the sole purpose of entering into a Plan of Reorganization and Asset Purchase Agreement with Allarity Delaware in order to reorganize the Company as a holding company listed on the US Nasdaq Stock Market and complete a 50 to 1 share reverse split, resulting in an immediate decrease in the outstanding shares used to calculate the weighted average common shares outstanding for basic and diluted net income per share. The reorganization is a common control transaction and there will be no change in control over the assets of the ultimate parent. Consequently, Allarity Delaware will record all assets and liabilities acquired from Allarity Therapeutics A/S at historical cost. The recapitalization share exchange is conditioned upon the approval of the Company’s shareholders and an effective registration statement filed with the US Securities and Exchange Commission. Our Form S-4 registration statement was effective on November 5, 2021; and the recapitalization was approved by our shareholders at our Extraordinary General Meeting held on November 22, 2021. Approximately 8,075,824 shares of Delaware common stock were issued in the recapitalization share exchange to the Company’s shareholders. ii. PIPE Investment On May 20, 2021, the Company entered into an Investment Agreement (the “Investment Agreement”) with the Investor whereby the Company agreed to issue and sell the Investor 20,000 shares of Allarity Delaware Series A Convertible Preferred Stock (the “Preferred Stock”) and common stock purchase warrants (the “Warrants”) for an additional $20 million (the “PIPE Investment”). The PIPE Investment is conditioned upon, and will occur simultaneously with, the consummation of the Recapitalization Share Exchange and the approval of Allarity Delaware’s application to list its common stock on the US Nasdaq Stock Market. The Preferred Stock may convert over time into at approximately 20% of the Company’s issued and outstanding shares however, conversion of the Preferred Shares and exercise of the Warrants; is limited to 4.99% of the Company’s issued and outstanding shares. As of the date of these financial statements the Company expects the conversion price of the Preferred Stock to be $9.91 per share. However, if the volume weighted average price for Allarity Delaware common stock on the US Nasdaq Stock Market falls below the fixed conversion price for the preferred stock, then the preferred stock would be entitled to convert at an alternate conversion price between 80% to 90% of the volume weighted average price at the time of conversion with a similar adjustment for the exercise price for the warrants. Lastly, if the average daily US dollar volume of share of Allarity Delaware common stock traded on the US Nasdaq Stock Market falls below $2.5 million, then holders of the convertible preferred stock will be entitled to a one-time special dividend of 8% of the stated value of the preferred stock ($1.6 million) payable in shares of common stock upon conversion of the convertible preferred stock. The Company is in the process of assessing the accounting treatment of the special dividend. (b) Subsequent events as of May 16, 2022, as reported on the re-filing date of the restated September 30, 2021 10-Q i. Oncoheroes Effective January 2, 2022, the Company entered into an Exclusive License Agreement with Oncoheroes Biosciences Inc. (the “Oncoheroes Agreement”) to grant Oncoheroes an exclusive royalty-bearing global license to both dovitinib and stenoparib in pediatric cancers. Oncoheroes will take responsibility for pediatric cancer clinical development activities for both clinical-stage therapeutics. Allarity will support Oncoheroes’ pediatric clinical trials by providing clinical-grade drug inventory at cost and by facilitating DRP® companion diagnostic screening of pediatric patients for each drug. Under the licenses, Oncoheroes will receive commercialization rights for pediatric cancers, subject to the Company’s first buy-back option for each program, and the Company will receive an upfront license fee and regulatory milestones for each program, specifically one for dovitinib and one for stenoparib, as follows: i. a one-time upfront payment of $250 and $100 for stenoparib and dovitinib respectively, within 5 business days after January 2, 2022 ($350 received as of April 4, 2022); and ii. two milestone payments of $1,000 each due and payable upon receipt of regulatory approval of a product in the United States, and of a product in Europe, respectively. Pursuant to the Oncoheroes Agreement Allarity is also entitled to tiered royalties on aggregate net product sales (“Sales”) of between 7% and 12% on net sales of products as follows: 7% on Sales less than $100 million; 10% on Sales of greater than $100 million and less than $200 million; and 12% on Sales greater than $200 million. ii. Lantern Pharma, Inc. – Irofulven Agreement On July 23, 2021, we entered into an Asset Purchase Agreement with Lantern Pharma, Inc. relating to our inventory of Irofulven active pharmaceutical ingredients, our clinical research data relating to Irofulven developed by us during the drug development program under the May 2015 Drug License and Development Agreement for Irofulven and terminated our obligation to further advance the development of Irofulven under the May 2015 agreement. Under the Asset Purchase Agreement, Lantern Pharma agreed to pay us $1 million on closing of the transaction, and additional amounts (i) when the inventory of Irofulven API is recertified with a longer shelf life, (ii) upon the initiation of treatment of the first patient in an investigator-led “compassionate use” ERCC2/3 mutation subgroup study using Irofulven in certain agreed upon investigators; and (iii) upon the initiation of treatment of the second patient within an agreed upon time period after the closing of the transaction in any human clinical trial of Irofulven initiated by Lantern Pharma. In addition to the sale of our inventory of Irofulven API and Data to Lantern Pharma, we also granted Lantern Pharma a non-exclusive, worldwide license to use our putative Irofulven DRP® companion diagnostic to advance the development and commercialization of Irofulven and other Illudins (sesquiterpenes with anti-tumor properties produced by some mushrooms). We have also agreed not to engage in any drug development program for Illudins or any of its analogues or any use thereof for a period of five (5) years. Effective March 18, 2022, pursuant to clause (i) the inventory was recertified with a longer shelf life and as of March 31, 2022, we received $459. iii. Series A Preferred Stock Conversions Between December 21, 2022, and March 31, 2022, 2,173 Series A Preferred shares (gross value of $2,319) were converted into 766,466 shares of our common stock and accordingly the balance of outstanding Series A Preferred shares was reduced to 17,827 at March 31, 2022. The latest three conversions in March 2022 were completed at less than the agreed floor price and accordingly, we recorded a liability of $134. iv. 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, LP 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 2(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 the Triggering Event is cured or the receipt by the Investor 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 the Investor’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. On May 4, 2022, the Company and the Investor entered into a Forbearance Agreement and Waiver, dated April 27, 2022, wherein the Investor 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 the Investor’s legal fees incurred in the preparation of the Forbearance Agreement and Waiver in the aggregate of $538,823.00 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, the Investor 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, the Investor 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. v. Impairment of Intangible Assets At the end of March 31, 2022, the Company’s share price has declined significantly, resulting in a market valuation well below the carrying value of the Company’s intangible assets. Consequently, the Company will be testing its intangible assets for impairment as of the end of March 31, 2022.

Accounting Policies [Abstract]
Reorganization	(a) Reorganization Effective December 20, 2021, and in connection with the Plan of Reorganization and Asset Purchase Agreement which was amended and restated on September 23, 2021, between Allarity Therapeutics, Inc. a Delaware corporation (the “Company”), Allarity Acquisition Subsidiary Inc., the Company’s wholly owned Delaware subsidiary (“Acquisition Sub”), and Allarity Therapeutics A/S, an Aktieselskab organized under the laws of Denmark (“Allarity A/S”), the Company completed an Asset Purchase Agreement with Acquisition Sub and Allarity A/S pursuant to which Allarity A/S sold, and Acquisition Sub purchased, all of Allarity A/S’ assets and certain specified liabilities in connection with Allarity A/S’ business for an aggregate purchase price of 8,075,824 shares of the Company’s common stock plus the assumption of specified liabilities. Thereafter, Allarity A/S is in the process of being dissolved and liquidated in accordance with Part 14 of Danish Companies Act. While Allarity Therapeutics, Inc. was the legal acquirer of Allarity Therapeutics A/S, for accounting purposes, the Merger is treated similarly to a reverse recapitalization, whereby Allarity Therapeutics A/S is deemed to be the accounting acquirer, and the historical financial statements of Allarity Therapeutics A/S became the historical financial statements of Allarity Therapeutics, Inc. upon the closing of the reorganization. Under this method of accounting, Allarity Therapeutics, Inc. was treated as the “acquired” company and Allarity Therapeutics A/S is treated as the acquirer for financial accounting purposes. Accordingly, for accounting purposes, the reorganization was treated as the equivalent of Allarity Therapeutics A/S issuing stock for the net assets of Allarity Therapeutics, Inc. accompanied by a recapitalization. Because the reorganization is a common control transaction the net assets and prior year financial statements were stated at historical cost, with no goodwill or other intangible assets recorded. In accordance with ASC 805, the legal capital of Allarity Therapeutics A/S has been retroactively adjusted to reflect the capital of the legal acquirer (accounting acquiree) Allarity Therapeutics, Inc.
Principal Operations and Activities	(b) Principal Operations and Activities The Company’s principal operations are located at Venlighedsvej 1, 2970 Horsholm, Denmark. The Company’s United States operations are located at 210 Broadway #201, Cambridge, MA 012139, United States of America. The Company develops drugs for the personalized treatment of cancer using drug specific companion diagnostics (cDx) generated by its proprietary drug response predictor technology, DRP ®
Liquidity and Going Concern	(c) 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 financial statements do not reflect any adjustments relating to the recoverability and reclassifications 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 management’s evaluation under the requirements of Accounting Standard Codification (ASC) 205-40. Since inception, the Company has devoted substantially all of 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 $49.7 million and $39.8 million as of September 30, 2021 and December 31, 2020 respectively. As of August 20, 2021, the issuance date of the financial statements for the year ended December 31, 2020, our cash which included the proceeds of our rights offering in June 2021 was insufficient to fund our current operating plan and planned capital expenditures for at least the next 12 months. As of May 16, 2022, our cash is insufficient to fund our current operating plan and planned capital expenditures for the next 12 months. These conditions give rise to a 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. 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 into 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. The Company entered into a Securities Purchase Agreement with the holder of all of the Company’s Series A Preferred Stock (the “Investor”) that provides for a $20 million equity investment in the Company. Please refer to the subsequent event disclosures in note 19 for further information. 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. Further, at the date of this filing the above noted Investor $20 million equity investment cannot be asserted as probable and is subject to close of the transaction. 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.
Basis of Presentation	(d) Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”). The accompanying interim condensed consolidated financial statements as of September 30, 2021, and for the three and nine months ended September 30, 2021 and 2020, and related interim information contained within the notes to the financial statements, are unaudited. In management’s opinion, the unaudited interim condensed consolidated financial statements have been prepared on the same basis as the Company’s audited financial statements and include all adjustments (including normal recurring adjustments) necessary for a fair statement of the financial statements. The condensed consolidated balance sheet at December 31, 2020, was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and accompanying notes included in its Form S-4 for the year ended December 31, 2020, filed on August 20, 2021, and as amended. The results for the three and nine months ended September 30, 2021, are not necessarily indicative of the results expected for the full fiscal year or any interim period. As a result of the recapitalization share exchange (also described in Note 1), to these financial statements, all outstanding shares, warrants, and options were exchanged on a 50:1 basis as of December 20, 2021, and accordingly, all share, warrant, option and per share disclosure in these financial statements has been retroactively adjusted to reflect the 50:1 reverse split unless otherwise stated.
Principles of Consolidation	(e) 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 Oncology Venture US Inc. United States All intercompany transactions and balances, including unrealized profits from intercompany sales, have been eliminated upon consolidation.
Use of Estimates	(f) Use of Estimates The preparation of 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 convertible loan, the accrual for research and development expenses, revenue recognition, fair values of acquired intangible assets and impairment review of those assets, the useful life of property, plant and equipment, share based compensation expense, provisions for contingencies and litigation, 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 in light of 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.
Computation of Earnings (Loss) per Share	(g) Computation of Earnings (Loss) per Share The Company computes net (loss) income per share in accordance with ASC Topic 260, “Earnings Per Share” (“ASC 260”) and related guidance, which requires two calculations of net (loss) income attributable to the Company’s shareholders per share to be disclosed: basic and diluted. Basic loss per share is derived by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during each period. Diluted loss per share includes the effect, if any, from the potential exercise or conversion of securities, such as warrants, and convertible debt, which would result in the issuance of incremental shares of common stock unless such effect is anti-dilutive. In calculating the basic and diluted net loss per share applicable to common stockholders, the weighted average number of shares remained the same for both calculations since when a net loss exists, dilutive shares are not included in the calculation.
Conversion of foreign currencies	(h) Conversion of foreign currencies 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 shareholders’ equity as a component of accumulated other comprehensive (loss) income. Monetary assets and liabilities denominated in currencies other than the functional currency are re-measured 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 profit or loss for the respective periods. Adjustments that arise from exchange rate changes on transactions denominated in a currency other than the local currency are included in other comprehensive income (loss) in the consolidated statements of operations and comprehensive loss as incurred.
Accumulated other comprehensive income (loss)	(i) Accumulated other comprehensive income (loss) Accumulated other comprehensive income (loss) includes all changes in equity except those resulting from investments by owners and distributions to owners, including accumulated foreign currency translation, and changes in instrument specific credit risk. During the three months ended September 30, 2021, and 2020 the Company recorded accumulated foreign currency translation losses of ($939) and gains of $1,130 respectively. During the nine months ended September 30, 2021, and 2020 the Company recorded accumulated foreign currency translation losses of ($1,785) and gains of $1,212 and instrument specific credit risk losses of ($9) and gains of $6 respectively. These amounts have been recorded as a separate component of stockholders’ equity (deficit).
Contingencies	(j) 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.
JOBS Act accounting election	(k) JOBS Act accounting election The Company is an “emerging growth company”, as defined in the Jumpstart Our Business Startups Act of 2012 (JOBS Act). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies; however, the Company may adopt new or revised accounting standards early if the standard allows for early adoption.
Recently Issued Accounting Pronouncements	(l) Recently Issued Accounting Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (the “FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. ASUs not listed below 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.
Adopted	Adopted In December 2019, the FASB issued ASU 2019-12, “Income Taxes — Simplifying the Accounting for Income Taxes”. The ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles as well as clarifying and amending existing guidance to improve consistent application. The amendments to this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. Depending on the amendment, adoption may be applied on the retrospective, modified retrospective or prospective basis. The Company has adopted this standard on a prospective basis with no significant impact upon its consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. ASU No. 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. ASU No. 2020-06 is effective for public companies for annual periods beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted for annual periods beginning after December 15, 2020, and interim periods within those fiscal years. The Company has early adopted this standard effective January 1, 2021 on a modified retrospective basis with no significant impact on its consolidated financial statements.
Not Yet Adopted	Not Yet Adopted In May 2021, the FASB issued ASU No. 2021-04 — Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options — to clarify the accounting by issuers for modifications or exchanges of equity-classified warrants. The framework applies to freestanding written call options, such as warrants, that were and remain equity classified by the issuer after the modification and are not in the scope of another Codification Topic. The framework applies regardless of whether the modification is through an amendment to the existing terms or issuance of a replacement warrant. The effect of the modification of the warrant is measured as the difference in its fair value immediately before and after the modification. The effect is recognized in the same manner as if cash had been paid as consideration. Additionally, other modifications may need to be accounted for as a cost to the issuing entity based on the substance of the transaction. The Update is effective prospectively for fiscal years beginning after December 15, 2021, including interim periods therein, with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.
