Nature of Operations and Summary of Significant Accounting Policies
Nature of Operations and Summary of Significant Accounting Policies	Nature of Operations Ideanomics, Inc. (Nasdaq: IDEX) is a Nevada corporation that primarily operates in Asia and the United States through its subsidiaries and variable interest entities (“VIEs.”) Unless the context otherwise requires, the use of the terms “we,” “us,” “our” and the “Company” in these notes to condensed consolidated financial statements refers to Ideanomics, Inc., its consolidated subsidiaries and VIEs. The Company’s chief operating decision maker has been identified as the chief executive officer, who reviews consolidated results when making decisions about allocating resources and assessing performance of the Company. Through June 30, 2021, the Company operates in one two With four Ideanomics Mobility is driving EV adoption by assembling a synergistic ecosystem of subsidiaries and investments across the three Ideanomics Capital is the Company’s fintech business unit, which focuses on leveraging technology and innovation to improve efficiency, transparency, and profitability for the financial services industry. Basis of Presentation In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments of a normal recurring nature that are necessary for a fair presentation of the results for the interim periods presented. All significant intercompany transactions and balances are eliminated in consolidation. However, the results of operations included in such financial statements may not necessary be indicative of annual results. The Company uses the same accounting policies in preparing quarterly and annual financial statements. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the Securities and Exchange Commission (“SEC”) on March 31, 2021 (“2020 Form 10-K.”) Immaterial Revision to Prior Period The Company determined that a legal agreement the Company entered into whereby the Company took possession of a property in Qingdao, China for no consideration was incorrectly accounted for as a lease in accordance with ASC 842, Leases however, the Company has revised its condensed consolidated financial statements to properly account for this transaction. The adjustment to the condensed consolidated balance sheet as of December 31, 2020 is, as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Account December 31, ​ ​ December 31, ​ ​ 2020 ​ ​ ​ ​ 2020 ​ ​ (As Reported) ​ Adjustment ​ (As Revised) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Operating lease right of use assets ​ $ 7,117 ​ $ (6,962) ​ $ 155 Other non-current assets ​ 516 ​ 6,962 ​ 7,478 Current portion of lease liabilities ​ 430 ​ (315) ​ 115 Other current liabilities ​ 1,920 ​ 315 ​ 2,235 Operating lease liability – long-term ​ 6,759 ​ (6,740) ​ 19 Other long-term liabilities ​ 535 ​ 6,740 ​ 7,275 ​ See Note 2 for adjustments for this matter as of and for the period ended June 30, 2021. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as the related disclosure of contingent assets and liabilities. Actual results could differ from those estimates. On an ongoing basis, management evaluates the Company’s estimates, including those related to the bad debt allowance, variable consideration, fair values of financial instruments, intangible assets (including digital currencies) and goodwill, useful lives of intangible assets and property and equipment, asset retirement obligations, income taxes, and contingent liabilities, among others. The Company bases its estimates on assumptions, both historical and forward looking, that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Significant Accounting Policies For a detailed discussion of Ideanomics’ significant accounting policies, refer to Note 2 — “Summary of Significant Accounting Policies,” in Ideanomics’ consolidated financial statements included in the Company’s 2020 Form 10-K. During the six months ended June 30, 2021, the Company acquired four businesses, Timios Holdings Corp. (“Timios,”) Wireless Advanced Vehicle Electrification, Inc. (“WAVE,”) US Hybrid ("U S Hybrid,") and Solectrac, Inc. ("Solectrac,") which resulted in the adoption of the following accounting policies with respect to those businesses: Timios Title Revenue Premiums from title insurance policies written by independent agencies are recognized net of commission costs when the policies are reported to Timios and not before the effective date of the policy. Regulation of title insurance rates varies by state. Premiums are charged to customers based on rates predetermined in coordination with each states’ respective Department of Insurance. Closing Revenue A closing or escrow is a transaction pursuant to an agreement of a buyer, seller, borrower, or lender wherein an impartial third-party, such as Timios, acts in a fiduciary capacity on behalf of the parties in accordance with the terms of such agreement in order to accomplish the directions stated therein. Services provided include, among others, acting as escrow or other fiduciary agent, obtaining releases, and conducting the actual closing or settlement. Closing and escrow fees are recognized upon closing of the escrow, which is generally at the same time of the closing of the related real estate transaction. Appraisal Revenue Revenue from appraisal services are primarily related to establishing the ownership, legal status and valuation of the property in a real estate transaction. In these cases, Timios does not issue a title insurance policy or perform duties of an escrow agent. Revenues from these services are recognized upon delivery of the service to the customer. Title Plant Title plant consists of costs incurred to construct the title plant and to obtain, organize and summarize historical information for Glenn County title searches. These costs were capitalized until such time as the plant was deemed operational to conduct title searches and issue title insurance policies. Management has determined that the title plant has been properly maintained, has an indeterminable life, and in accordance with Accounting Standards Codification (“ASC”) Topic 950, Financial Services – Title Plant Software Development Costs Software developed or obtained for internal use in accordance with ASC 350-40, Internal-Use Software Escrow and Trust Deposits In providing escrow services, Timios holds funds for others in a fiduciary capacity, pending completion of real estate transactions. A separate, self-balancing set of accounting records is maintained by Timios to record escrow transactions. Escrow trust funds held for others are not Timios’s and, therefore, are excluded from the accompanying condensed consolidated balance sheet, however, Timios remains contingently liable for the disposition of these deposits. Escrow trust balances at June 30, 2021 were $41.1 million. It is a common industry practice for financial institutions where escrow funds are deposited to either reimburse or to directly provide for certain costs related to the delivery of escrow services. Timios follows the practice of non-recognition of costs borne by the financial institution where escrow funds are deposited. WAVE, U S Hybrid, and Solectrac (collectively, the acquired EV entities) Inventory Inventories, which include the costs of material, labor and overhead, are stated at the lower of cost or net realizable value, with cost generally computed on a first-in, first-out (“FIFO”) basis. Estimated losses from obsolete and slow-moving inventories are recorded to reduce inventory values to their estimated net realizable value and are charged to costs of revenue. At the point of loss recognition, a new cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in a recovery in carrying value. The composition of inventory is as follows (in thousands): ​ ​ ​ ​ ​ June 30, 2021 Raw materials ​ $ 736 Work in progress ​ 39 Finished goods ​ 2,798 Total ​ $ 3,573 ​ Revenue For product sales, the acquired EV entities consider practical and contractual limitations in determining whether there is an alternative use for the product. For example, long-term design and build contracts are typically highly customized to a customer’s specifications. For contracts with no alternative use and an enforceable right to payment for work performed to date, including a reasonable profit if the contract were terminated at the customer’s convenience for reason other than nonperformance, the acquired EV entities recognize revenue over time. All other product sales are recognized at a point in time. For contracts recognized over time, the acquired EV entities use the cost-to-total cost method or the units of delivery method, depending on the nature of the contract, including length of production time. For contracts recognized at a point in time, the acquired EV entities recognize revenue when control passes to the customer, which is generally based on shipping terms that address when title and risk and rewards pass to the customer. However, the acquired EV entities also consider certain customer acceptance provisions as certain contracts with customers include installation, testing, certification or other acceptance provisions. In instances where contractual terms include a provision for customer acceptance, the acquired EV entities consider whether they have previously demonstrated that the product meets objective criteria specified by either the seller or customer in assessing whether control has passed to the customer. For service contracts, the acquired EV entities recognize revenue as the services are rendered if the customer is benefiting from the service as it is performed, or otherwise upon completion of the service. Separately priced extended warranties are recognized as a separate performance obligation over the warranty period. The transaction price in the acquired EV entities’ contracts consists of fixed consideration and the impact of variable consideration including returns, rebates and allowances, and penalties. Variable consideration is generally estimated using a probability-weighted approach based on historical experience, known trends, and current factors including market conditions and status of negotiations. For design and build contracts, the acquired entities may at times collect progress payments from the customer throughout the term of the contract, resulting in contract assets or liabilities depending on the timing of the payments. Contract assets consist of unbilled amounts when revenue recognized exceeds customer billings. Contract liabilities consist of advance payments and billings in excess of revenue recognized. Design and engineering costs for highly complex products to be sold under a long-term production-type contract are deferred and amortized in a manner consistent with revenue recognition of the related contract or anticipated contract. Other design and development costs are deferred only if there is a contractual guarantee for reimbursement. Costs to obtain a contract (e.g., commissions) for contracts greater than one year are deferred and amortized in a manner consistent with revenue recognition of the related contract. Product Warranties The acquired EV entities’ standard product warranty terms generally include post-sales support and repairs or replacement of a product at no additional charge for a specified period of time. Accruals for estimated expenses related to product warranties are made at the time revenue is recognized and are recorded as a component of costs of revenue. The acquired EV entities estimate the liability for warranty claims based on standard warranties, the historical frequency of claims and the cost to replace or repair products under warranty. Factors that influence the warranty liability include the number of units sold, the length of warranty term, historical and anticipated rates of warranty claims and the cost per claim. The warranty liability as of June 30, 2021 is $0.6 million and is included in “Other long-term liabilities” within the condensed consolidated balance sheet. The warranty liability has not changed substantially subsequent to WAVE’s acquisition. Effects of COVID 19 Novel Coronavirus 2019 (“COVID-19”) is an infectious disease cause by severe acute respiratory syndrome coronavirus. The disease was first identified in December 2019 in Wuhan, the capital of China’s Hubei province, and has since spread globally, resulting in the ongoing COVID-19 pandemic. As of July 31, 2021, over 197.6 million cases had been reported across the globe, resulting in 4.2 million deaths. The spread of COVID-19 has caused significant disruption to society as a whole, including the workplace. The resulting impact to the global supply chain has disrupted most aspects of national and international commerce, with government-mandated social distancing measures imposing stay-at-home and work-from-home orders in almost every country. The effects of social distancing have shut down significant parts of the local, regional, national, and international economies, for limited or extended periods of time, with the exception of government designated essential services. In many parts of the world, stay-at-home and work-from-home orders were relaxed during the summer of 2020 as the effects of the Coronavirus appeared to lessen, and economic activity began to recover. However, commencing in the autumn and fall of 2020 and continuing, the U.S. as well as countries in Europe, South America and Asia began to experience an increase in new COVID-19 cases, and in some cases local, state, and national governments began to reinstate restrictive measures to stem the spread of the virus. The U.S. and other countries also experienced an increase in new COVID-19 cases after the fall and winter holiday season, with new, more infectious variants of COVID-19 identified. Various vaccines have been developed, with vaccinations programs in effect worldwide, though reaching acceptable levels of immunization against COVID-19 remains challenging at the local, regional and global level remains challenging. The future effects of the virus are difficult to predict, due to uncertainty about the course of the virus, different variants that may evolve, and the supply of the vaccine on a local, regional, and global basis, as well as the ability to implement vaccination programs in a short time frame. The Company does not anticipate significant adverse effects on its operations’ revenue as compared to its business plan in the near- or mid-term, although the future effects of COVID-19 may result in regional restrictive measures which may constrain the Company’s operations, and supply chain shortages of various materials may have a negative effect on our EV sales or production capacity in the longer-term. The Company’s Treeletrik business, which focuses on the sale of motorbikes in the ASEAN region, is experiencing disruption in its operations as a result the continued lockdowns in the region, which have adversely impacted its ability to fulfill committed orders. The Company continues to monitor the overall situation with COVID-19 and its effects on both local, regional and global economies. New Accounting Pronouncements Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2019-12 (“ASU 2019-12”) “ Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes Income Taxes In August 2020, the FASB issued ASU No. 2020-06 (“ASU 2020-06”) “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.” January 1, 2021. As the Company had no outstanding convertible instruments as of that date, the adoption of ASU 2020-06 had no effect. Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13 (“ASU 2016-13”) “ Financial Instruments - Credit Losses” (“ASC 326:”) Measurement of Credit Losses on Financial Instruments Financial Instruments – Credit Losses (Topic 326,) Derivatives and Hedging (Topic 815,) and Leases (Topic 842) In May 2021, the FASB issued ASU No. 2021-04 (“ASU 2021-04”) “Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation— Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815- 40)”

Restatement of Previously Reported Condensed Consolidated Financial Statements
Restatement of Previously Reported Condensed Consolidated Financial Statements	Note 2. As previously disclosed on Form 8-K filed on November 16, 2021, the Company determined that the Company’s previously issued financial statements for the periods ended March 31, 2021 and June 30, 2021 should no longer be relied upon due to errors in such condensed consolidated financial statements related to revenue reported by Timios that provides title and agency services. The preparation of the Company’s condensed consolidated financial statements identified additional transactions and accounting practices not in accordance with U.S. GAAP. The following errors were identified as part of the restatement: A. The Company determined that it did not present Timios title and agency services revenue and the related cost of revenue in accordance with US GAAP on the condensed consolidated statement of operations, as premiums from title insurance policies written by independent agencies were presented on a gross basis and did not properly present revenue and cost of revenue net of commission costs. B. The Company discovered that it did not properly account for its investment in Technology Metals Market Limited (“TM2”) in accordance with the equity method of accounting.In addition, the Company determined that it incorrectly presented equity income (loss) on its equity method investments as a component of interest and other income (expense) on the condensed consolidated statements of operations rather than as a separate financial statement caption below income taxes. C. The Company discovered certain errors in determining the estimated fair value of acquired intangible assets in its purchase price allocation for its acquisitions. D. The Company determined that the errors in determining the estimated fair value of net assets acquired in its acquisitions resulted in an additional reduction to the Company’s deferred tax liabilities. E. The Company determined that it did not properly recognize income tax expense (benefit) for certain acquired entities subsequent to their respective acquisitions during the six months ended June 30, 2021.

Acquisitions and Divestitures
Acquisitions and Divestitures	Note 6. Acquisitions and Divestitures The Company may divest certain businesses from time to time based upon review of the Company’s portfolio considering, among other items, factors relative to the extent of strategic and technological alignment and optimization of capital deployment, in addition to considering if selling the businesses results in the greatest value creation for the Company and for shareholders. The Company had not acquired any companies nor disposed of any subsidiaries in the year ended December 31, 2020, with the exception of the disposition of its remaining 10.0% interest in Amer Global Technology Limited (“Amer.”) In the three months ended September 30, 2020, the Company sold its remaining 10.0% interest in Amer to Fintalk Media Inc., a related party, for a nominal amount. As the Company had no basis in its remaining interest in Amer, the gain recognized on the sale was de minimis. 2021 Acquisitions The Company has completed the below acquisitions in the six months ended June 30, 2021. The accompanying condensed consolidated financial statements include the operations of the acquired entities from their respective acquisition dates. All of the acquisitions have been accounted for as business combinations. Accordingly, consideration paid by the Company to complete the acquisitions is initially allocated to the acquired assets and liabilities assumed based upon their estimated acquisition date fair values. The recorded amounts for assets acquired and liabilities assumed are provisional and subject to change during the measurement period, which is up to 12 months from the acquisition date. The acquisitions below are collectively defined as the 2021 Acquisitions. Timios Holdings Corp. On January 8, 2021, the Company completed the acquisition of privately held Timios and its affiliates pursuant to the stock purchase agreement (the “Timios Agreement”) entered into on November 11, 2020. Pursuant to the Timios Agreement, the Company acquired 100% of the outstanding capital stock of Timios for a purchase price of $40.0 million, net of cash acquired of $6.5 million. The full purchase price was paid in cash. Pursuant to the Timios Agreement, $5.1 million of the cash consideration was paid into escrow pending a one year indemnification review. Timios provides title and escrow services for real estate transactions. Revenue of $22.1 million and $46.9 million and net income of $1.9 million and $5.3 million for the three and six months ended June 30, 2021, respectively, have been included in the condensed consolidated financial statements. Wireless Advanced Vehicle Electrification, Inc. On January 15, 2021, the Company completed the acquisition of privately held WAVE pursuant to an agreement and plan of merger (the “WAVE Agreement”) entered into on January 4, 2021. WAVE is a provider of wireless charging solutions for medium and heavy-duty electric vehicles. Pursuant to the WAVE Agreement, the Company acquired 100% of the outstanding capital stock of WAVE for an aggregate purchase price of $55.0 million in a combination of $15.0 million of cash plus a total of 12.6 million unregistered shares of the Company’s common stock, valued at $40.0 million at the date of closing. Pursuant to the Wave Agreement, $5 million of the cash consideration was paid into escrow pending a one year indemnification review. The WAVE Agreement provided that 3.6 million shares of the Company’s common stock be held back at closing, to be released upon the receipt of certain customer consents not obtained prior to closing. As of June 30, 2021, 2.4 million of the Company’s common stock remains unissued pending receipt of the consents. Since receipt of the consents is probable, the Company has included these common shares as contingent consideration as of the acquisition date of $7.7 million. Pursuant to the original agreement, if any such consent is not obtained within six months following the closing date, the portion of the common stock allocated to such consent in the WAVE Agreement would not be issued to the sellers. The Company intends to extend the time frame for this contractual provision as the receipt of the consents is outside the control of the former WAVE shareholders. In addition to the purchase price to be paid at closing, the WAVE Agreement contains three earnouts that could result in additional payments of up to $30.0 million to the sellers based upon: (1) revenue and gross profit margin metrics in calendar year 2021; (2) revenue and gross profit margin metrics in calendar year 2022; and (3) revenue and gross profit margin metrics for 2021 and 2022 collectively. The Company considers this earnout to be contingent consideration that as of the acquisition date is unlikely to occur and has therefore attributed zero value for purposes of the preliminary purchase price allocation. The Company will continue to monitor the fair value of this contingent considerations with any changes being recorded in the consolidated statement of operations if and when a change occurs. Ideanomics has also agreed to a performance and retention plan for the benefit of certain WAVE’s employees which could result in up to $10.0 million paid to such employees if certain gross revenue targets and certain gross profit margins are achieved for calendar years 2021 and 2022. Consistent with the conclusion on the earnout contingent consideration, the Company has not accrued any of this retention plan as the revenue and gross profit margin criteria are unlikely to be met. Revenue of $2.4 million and $4.2 million and net loss of $1.3 million and $1.9 million, for the three and six months ended June 30, 2021, respectively, have been included in the condensed consolidated financial statements. US Hybrid On June 10, 2021, the Company completed the acquisition of privately held US Hybrid Corporation ("US Hybrid") pursuant to an agreement and plan of merger (the “USH Agreement”) entered into on May 12, 2021. US Hybrid specializes in the design and manufacturing of zero-emission electric powertrain components including traction motors, controllers, auxiliary drives, energy storage and fuel cell engines for electric, hybrid, and fuel cell medium and heavy-duty municipality vehicles, commercial trucks, buses, and specialty vehicles throughout the world. Pursuant to the USH Agreement, the Company acquired 100% of the outstanding capital stock of US Hybrid Corporation for an aggregate purchase price of $50.0 million in a combination of $30.0 million in cash and 6.6 million in unregistered shares of the Company’s common stock, valued at $20.9 million at the date of closing. Pursuant to the USH Agreement, $1.0 million of cash consideration was paid into escrow pending a true up of net working capital within 90 days of the closing date. Additionally, the 6.6 million shares were paid into an indemnity escrow to satisfy future indemnification obligations of the selling shareholders, if any. The Company has also agreed to a performance and retention plan for the benefit of certain US Hybrid employees which could result in up to $18.7 million paid to such employees if certain gross revenue targets, gross profit margins and certain operational targets are achieved for calendar years 2021, 2022 and 2023. The Company has concluded that this performance and retention plan does not constitute purchase consideration and will be recorded as compensation expense when the criteria are probable of being met. As of June 30, 2021 the Company has not accrued any of this retention plan as the various criteria are unlikely to be met. Revenue of $0.3 million and net loss of $0.1 million have been included in the condensed consolidated financial statements since the acquisition date. Solectrac On June 11, 2021, the Company completed the acquisition of privately held Solectrac, Inc ("Solectrac") pursuant to an agreement and plan of merger (the “Solectrac Agreement”) entered into on June 11, 2021. Solectrac developed 100% battery-powered, all-electric tractors for agriculture and utility operations. Solectrac tractors provide an opportunity for farmers around the world to power their tractors by using the sun, wind, and other clean renewable sources of energy. Solectrac’s mission is to offer farmers independence from the pollution, infrastructure, and price volatility associated with fossil fuels. Pursuant to the Solectrac Agreement, the Company acquired the remaining 78.6% of the outstanding capital stock of Solectrac for an aggregate purchase price of $17.7 million in net cash. The Company had previously acquired 21.4% of Solectrac in 2020. The Company now owns 100% of Solectrac. Pursuant to the Solectrac Agreement, $2.0 million of cash consideration was paid into an indemnity escrow to satisfy future indemnification obligations of the selling shareholders, if any. In conjunction with the acquisition of Solectrac, the Company remeasured the 21.4% previously accounted for as an equity method investment. This remeasurement resulted in a gain of $2.9 million recorded in the condensed consolidated statement of operations. In addition to the purchase price to be paid at closing, the Solectrac Agreement contains three earnouts that could result in additional payments of up to $6.0 million to the sellers based upon: (1) revenue and gross profit margin metrics in calendar year 2021; (2) revenue and gross profit margin metrics in calendar year 2022; and (3) revenue and gross profit margin metrics in calendar year 2023. The Company considers this earnout to be contingent consideration that as of the acquisition date is probable to occur in certain years and has attributed $1.6 million as additional consideration for purposes of the preliminary purchase price allocation. The Company will continue to monitor the fair value of this contingent considerations with any changes being recorded in the consolidated statement of operations if and when a change occurs. The Company has also agreed to a performance and retention plan for the benefit of certain Solectrac employees which could result in up to $3.0 million paid to such employees if certain gross revenue targets, gross profit margins and certain operational targets are achieved for calendar years 2021, 2022 and 2023. The Company has concluded that this performance and retention plan does not constitute purchase consideration and will be recorded as compensation expense when the criteria are probable of being met. As of June 30, 2021 the Company has not accrued any of this retention plan as the various criteria are not yet probable of occurring. Revenue of $0.2 million and net income of zero have been included in the condensed consolidated financial statements since the acquisition date. Acquisition Method Accounting Estimates The Company initially recognizes the assets and liabilities acquired from the aforementioned acquisitions based on its preliminary estimates of their acquisition date fair values. As additional information becomes known concerning the acquired assets and assumed liabilities, management may make adjustments to the opening balance sheet of the acquired company up to the end of the measurement period, which is no longer than a one year period following the acquisition date. The determination of the fair values of the acquired assets and liabilities assumed (and the related determination of estimated lives of depreciable tangible and identifiable intangible assets) requires significant judgment. The table below reflects the Company’s provisional estimates of the acquisition date fair values of the assets acquired and liabilities assumed for the 2021 Acquisitions (in thousands) (as restated): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Solectrac US Hybrid Timios WAVE ​ ​ ​ ​ ​ ​ ​ ​ (As restated) ​ ​ ​ Purchase Price ​ ​ ​ ​ Cash paid at closing, including working capital estimates ​ $ 17,745 ​ $ 30,139 ​ $ 46,576 ​ $ 15,000 Fair value of previously held interest ​ 5,287 ​ — ​ ​ Fair value of common stock ​ — ​ 20,877 ​ — ​ 32,377 Fair value of contingent consideration ​ 1,639 ​ — ​ — ​ 7,657 Total purchase consideration ​ $ 24,671 ​ $ 51,016 ​ $ 46,576 ​ $ 55,034 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Purchase Price Allocation ​ ​ ​ ​ Assets acquired ​ ​ ​ ​ Current assets ​ 3,011 ​ 4,547 ​ 7,292 ​ 2,130 Property, plant and equipment ​ 30 ​ 5 ​ 429 ​ — Other assets ​ 45 ​ 52 ​ 49 ​ — Intangible assets – tradename ​ 4,570 ​ 1,740 ​ 7,780 ​ 12,630 Intangible assets – lender relationships ​ — ​ — ​ 14,970 ​ — Intangible assets - technology ​ 2,450 ​ 5,110 ​ ​ Intangible assets – patents ​ — ​ — ​ — ​ 13,000 Intangible assets – licenses ​ — ​ — ​ 1,000 ​ — Indefinite lived title plant ​ — ​ — ​ 500 ​ — Goodwill ​ 16,787 ​ 41,446 ​ 24,251 ​ 34,142 Total assets acquired ​ 26,893 ​ 52,900 ​ 56,091 ​ 61,903 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities assumed: ​ ​ ​ ​ Current liabilities ​ (509) ​ (2,083) ​ (4,306) ​ (3,778) Deferred tax liability ​ (1,713) ​ (802) ​ (5,209) ​ (3,091) Total liabilities assumed ​ (2,222) ​ (2,885) ​ (9,515) ​ (6,869) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net assets acquired ​ $ 24,671 ​ $ 51,016 ​ $ 46,576 ​ $ 55,034 ​ The useful lives of the intangible assets acquired is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Solectrac US Hybrid Timios WAVE Intangible assets – tradename 6 7 15 15 Intangible assets – lender relationships — — 7 — Intangible assets – technology 10 13 — 14 Intangible assets – non-compete — 5 — — Intangible assets – licenses — — 15 — Weighted average useful life 7.4 11.0 10 14.5 ​ Amortization expense related to intangible assets created as a result of the 2021 Acquisitions of $1.4 million and $2.2 million has been recorded for the three and six months ended June 30, 2021.

The goodwill from the 2021 Acquisitions represent future economic benefits that we expect to achieve as a result of the acquisitions, Goodwill is calculated as the excess of the consideration transferred over the net assets acquired and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The goodwill is not expected to be deductible for tax purposes for any of the 2021 Acquisitions. Goodwill will not be amortized but instead will be tested for impairment at least annually and more frequent if certain indicators of impairment are present. Transaction Costs Transaction costs describe the broad category of costs the Company incurs in connection with signed and/or closed acquisitions. Transaction costs include expenses associated with legal, accounting, regulatory, and other transition services rendered in connection with acquisition, travel expense, and other non-recurring direct expenses associated with acquisitions.

As a result, the Company recorded an impairment loss of $0.2 million related to leasehold improvements and other fixed assets at that location. Global Headquarters for Technology and Innovation in Connecticut (“Fintech Village”) On January 28, 2021, the Company’s Board of Directors accepted an offer of $2.75 million for Fintech Village, and subsequently signed a sale contract on March 15, 2021. The Company believes that Fintech Village met the criteria for held for sale classification on January 28, 2021. As the sale is expected to be completed within one year, the land with a carrying amount of $2.6 million and the asset retirement cost of $4.5 million are recorded as “Held for sale assets (Fintech Village”) in the current asset section of the condensed consolidated balance sheet. The Company has estimated the costs to sell Fintech Village to be $0.2 million and has recorded these costs in “Loss on disposal of subsidiaries, net.” The Company recorded asset retirement obligations for environmental remediation matters in connection with the acquisition of Fintech Village. The asset retirement obligations are not classified as held for sale as the purchaser will not assume these liabilities. However, as the sale of Fintech Village is expected to be completed within one year, the asset retirement obligations, which will be derecognized upon the sale, have been classified as current liabilities in the condensed consolidated balance sheet.

Long-term Investments The following table summarizes the Company’s long-term investments (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ June 30, December 31, ​ ​ 2021 ​ 2020 ​ ​ (As restated) ​ (As revised) Non-marketable equity investments ​ $ 12,032 ​ $ 4,787 Equity method investments ​ 20,144 ​ 3,783 Total ​ $ 32,176 ​ $ 8,570 ​ Non-marketable equity investment Non-marketable equity investments are investments in privately held companies without readily determinable fair values are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The Company reviews its equity securities without readily determinable fair values on a regular basis to determine if the investment is impaired. For purposes of this assessment, the Company considers the investee’s cash position, earnings and revenue outlook, liquidity and management ownership, among other factors, in its review. If management’s assessment indicates that an impairment exists, the Company estimates the fair value of the equity investment and recognizes an impairment loss that is equal to the difference between the fair value of the equity investment and its carrying amount. Based on management’s analysis of certain investment’s performance, no impairment losses were recorded in the three and six months ended June 30, 2021 and 2020. On January 28, 2021, the Company entered into a simple agreement for future equity (the “SAFE”) with Technology Metals Market Limited (“TM2”) pursuant to which Ideanomics invested £1.5 million ($2.1 million.) If there is an equity financing (of above one million pounds (1,000,000) during the twelve months immediately following execution of the SAFE, on the initial closing of such equity financing the SAFE will automatically convert into the number of ordinary shares equal to the purchase amount divided by the lowest price per share of the ordinary shares paid during such equity financing. If no equity financing has taken place during the twelve-month period immediately following the date of the SAFE, the parties shall in good faith attempt for one month to agree a fair value per ordinary share represented by the SAFE, following which the SAFE shall convert into the number of ordinary shares equal to the purchase amount divided by such fair value. If the parties are unable to establish a fair value per ordinary share within such one-month period, they shall jointly appoint and remunerate an expert valuer who shall deliver to both TM2 and Ideanomics simultaneously a written determination of fair value per ordinary share. Following receipt by both parties of such written determination, the SAFE shall convert into ordinary shares equal to the purchase amount divided by such fair value as determined by the expert valuer. Equity method investments The following table summarizes the Company’s investment in companies accounted for using the equity method of accounting (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ ​ ​ ​ (As restated) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Reclassification to ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Income (loss) ​ equity method ​ Reclassification to ​ Dilution loss due to ​ ​ ​ ​ ​ ​ ​ January 1, 2021 ​ Addition ​ on investment ​ investee ​ subsidiaries ​ investee share issuance ​ June 30, 2021 Solectrac (a) $ 2,556 $ — $ (153) $ — $ (2,372) $ (31) $ — TM2 (b) ​ 1,227 ​ 2,153 ​ (281) ​ ​ ​ ​ 3,099 Energica (c) ​ — ​ 13,555 ​ (264) ​ — ​ — ​ — ​ 13,291 FNL Technologies (d) ​ — ​ 3,504 ​ — ​ 250 ​ — ​ — ​ 3,754 Total ​ $ 3,783 ​ $ 19,212 ​ $ (698) ​ $ 250 ​ $ (2,372) ​ $ (31) ​ $ 20,144 ​ The Company has received no dividends from equity method investees in the three and six months ended June 30, 2021 and 2020. (a) Solectrac, Inc. (“Solectrac”) On October 22, 2020, the Company acquired 1.4 million common shares, representing 15.0% of the total common shares outstanding, of Solectrac for a purchase price of $0.91 per share, for total consideration of $1.3 million. On November 19, 2020, Ideanomics acquired an additional 1.3 million shares of common stock for $1.00 per share, for a subsequent investment of $1.3 million. The Company’ ownership in Solectrac was diluted to 24.3% as of March 31, 2021 due to the new share issuance by Solectrac during the three months ended March 31, 2021. On June 11, 2021, Ideanomics entered into a stock purchase agreement and plan of merger with Solectrac and its shareholders, and acquired the remaining common shares outstanding of Solectrac for total consideration of $17.7 million. Ideanomics now owns 100.0% of Soletrac, and commenced consolidation of Solectrac on that date. Refer to Note 6 for additional information on the acquisition of Solectrac. Solectrac develops, assembles and distributes 100% battery-powered electric tractors-an alternative to diesel tractors-for agriculture and utility operations. Solectrac tractors provide an opportunity for farmers around the world to power their tractors by using the sun, wind, and other clean renewable sources of energy. (b) Technology Metals Market Limited (“TM2”) On December 20, 2019, the Company acquired 20 common shares, representing 10.0% of the then outstanding shares for 1.7 million shares of the Company’s common stock valued at 1,000,000 British pounds (approximately $1.2 million). In connection with the acquisition of 20 common shares, the Company also received the right to appoint one person (of four) to the board of directors. Accordingly, the Company has significant influence over TM2. TM2 is a London based digital commodities issuance and trading platform for technology metals. It connects institutional investors, proprietary traders and retail investors with metals suppliers – miners, refiners, recyclers and mints. The platform focuses specifically on new metals that currently don’t have an active trading marketplace, such as rhodium, lithium, cobalt, rhenium, etc. (c) Energica Motor Company S.P.A. (“Energica”) On March 3, 2021, the Company entered into an investment agreement with Energica Motor Company S.P.A (“Energica.”) The Company invested €10.1 million ($13.6 million) for 6.1 million ordinary shares of Energica at a subscription price of €1.78 ($2.21) for each ordinary share. Pursuant to the purchase of the shares the Company will hold 20.0% of Energica’s share capital. From March 3, 2021 through September 30, 2021 the Company has the right to participate in any equity financing by Energica. Ideanomics was restricted from selling any of the shares for a period of 90 days. Energica is the world’s leading manufacturer of high performance electric motorcycles and the sole manufacturer of the FIM Enel MotoE ™ World Cup. Energica motorcycles are currently on sale through the official network of dealers and importers. The Company has decided to account for Energica on a one quarter lag as Energica, which is publicly traded on the Milan stock exchange, is only required to prepare and file semi-annual and annual financial statements, and the time frame in which the filings must be complete is much more lenient than in the U.S. Energica prepares its financial statements in accordance with Article 2423 et seq of the Italian Civil Code, rather than U.S. GAAP. Energica’s financial statements will either be prepared in or reconciled to U. S. GAAP prior to the Company recording its share of Energica’s earnings or losses, and the one quarter lag will be utilized to accomplish this, as well as related disclosure matters. As of June 30, 2021, the excess of the Company’s investment over its proportionate share of Energica’s net assets was $11.2 million. The difference represents goodwill and is not being amortized. Certain shareholders of Energica have rights such that they may convert their ordinary shares into ordinary shares with supervoting rights under certain conditions. If some or all of these ordinary shares were converted into ordinary shares with supervoting rights, the Company’s ownership in Energica would be diluted, perhaps significantly. The aggregate market value of the Energica common shares owned by the Company was $23.2 million as of June 30, 2021. (d) FNL On April 20, 2021, Ideanomics entered into a stock purchase agreement with FNL, pursuant to which Ideanomics made an investment into FNL, which included the investment of $2.9 million cash into FNL, the issuance of 0.1 million shares of Ideanomics common stock, and 100.0% of the common stock outstanding of Grapevine. Ideanomics received 0.6 million shares of common stock of FNL at a subscription price of $8.09 per share of common stock, and Ideanomics also converted a $250,000 Simple Agreement for Future Equity ("SAFE") into 30,902 shares of common stock.

Income Taxes
Income Taxes	Note 17. Income Taxes During the three months ended June 30, 2021 there was an income tax benefit of $1.6 million, During the six months ended June 30, 2021 there was an income tax benefit of $8.8 million. This benefit for the six months ended June 30, 2021 principally consisted of a reduction in the Company’s valuation allowance that resulted from the acquisitions, US Hybrid and Solectrac in the second quarter, and, Timios and WAVE, in the first quarter. In the case of each acquisition, intangible assets were recognized for financial reporting purposes that were not recognized for income tax purposes. This, in combination with some smaller temporary differences of four acquired businesses, resulted in the recognition of $11.0 million deferred tax liabilities, of which $2.7 million was in the three months ended June 30, 2021. The federal tax returns of all four acquired businesses will be included in the Ideanomics and subsidiaries consolidated U.S. federal tax return. WAVE will be included in the state tax returns of Ideanomics. The federal deferred tax liabilities, and the WAVE state deferred tax liabilities created, resulted in the valuation allowance on Ideanomics’ deferred tax assets being reduced by a similar amount. Ideanomics’ net deferred tax assets that had previously been judged to be more likely that not to be unable to reduce the Company’s income tax liability and consequently were completely offset by a valuation allowance. Once the acquisitions of four acquired businesses occurred, a portion of Ideanomics’ deferred tax assets could be utilized in offsetting the newly acquired deferred tax liabilities, this resulted in a one-time income tax benefit of $1.7 million during the three months ended June 30, 2021 and a one-time income tax benefit of $9.1 million during the six months ended June 30, 2021. Timios, US Hybrid and Soletrac have taxable income or loss reported on certain separate state tax returns and consequently have related state income tax expense or benefit. In the case of US Hybrid and Soletrac, which have losses, there are state income tax benefits consisting of those losses being used to reduce the state deferred tax liabilities recognized in the acquisitions. In the case of Timios, state income tax expense results from income. The net state income tax expense for Timios, US Hybrid and Solectrac was $0.1 million and $0.3 million for the three and six months ended June 30, 2021, respectively. There are no other material income tax expenses or benefits for the three and six months ended June 30, 2021 because of net operating loss and deferred tax assets related to the net operating loss carryovers utilized had been offset by a valuation allowance. The Company had established a 100% valuation allowance against its net deferred tax assets, excluding Timios, US Hybrid and Solectrac’s’ net state deferred tax liabilities, due to its history of pre-tax losses and the likelihood that the deferred tax assets will not be realized. During the three and six months ended June 30, 2020 income tax expense is nil because of net operating loss and deferred tax assets related to the net operating loss carryovers utilized had been offset by a valuation allowance. Company had established a 100% valuation allowance against its net deferred tax assets due to its history of pre-tax losses and the likelihood that the deferred tax assets will not be realized. There were no identified uncertain tax positions as of June 30, 2021 and December 31, 2020.

Concentration of Credit and Foreign Currency Risks
Concentration of Credit and Foreign Currency Risks	(a) Concentration of Credit Risks Financial instruments that potentially subject the Company to significant concentration of credit risk primarily consist of cash, cash equivalents, and accounts receivable. As of June 30, 2021, the Company’s cash was held by financial institutions (located in the PRC, Hong Kong, Malaysia, the U.S. and Singapore) that management believes have acceptable credit. Accounts receivable are typically unsecured. The risk with respect to accounts receivable is mitigated by regular credit evaluations that the Company performs on its distribution partners and its ongoing monitoring of outstanding balances. (b) Foreign Currency Risks A portion of the Company’s operating transactions are denominated in RMB. RMB is not freely convertible into foreign currencies. The value of the RMB is subject to changes in the central government policies and to international economic and political developments. In the PRC, certain foreign exchange transactions are required by laws to be transacted only by authorized financial institutions at exchange rates set by the People’s Bank of China (“PBOC.”) Remittances in currencies other than RMB by the Company in China must be processed through PBOC or other China foreign exchange regulatory bodies which require certain supporting documentation in order to complete the remittance.

The contractual period which required periodic remeasurement has expired, and therefore the Company will not remeasure this liability in the future. The fair value of DBOT contingent consideration as of June 30, 2021 was valued using the Black-Scholes Merton method. The Company issued 11.3 million shares during the six months ended June 30, 2020 and partially satisfied this liability. No shares have been issued in the six months ended June 30, 2021. 2 This represents the liability incurred in connection with the acquisition of Tree Technology shares during the fourth quarter of 2019 and as subsequently remeasured as of June 30, 2021. The fair value of the Tree Technology contingent consideration was valued using a scenario-based method which incorporates various estimates, including projected gross revenue for the periods, probability estimates, discount rates and other factors. 3 This represents the liability incurred in connection with the acquisition of WAVE. The liability represents the combination of the contingent shares and the earnout. The contingent shares are the remaining shares to be issued contingent on the receipt of certain customer consents as disclosed in Note 6. The fair value of this contingent consideration was valued using a scenario-based method that indicated based on the probabilities that 100% of the consents will be received. The earnout liability is dependent on WAVE achieving certain revenue and gross profit margin criteria in 2021, 2022 and cumulatively 2021 and 2022. The fair value of zero has been determined using a scenario-based method which indicated that none of the criteria are likely to be achieved. 4 This represents the liability incurred in connection with the acquisition of Solectrac. The liability represents the fair value of the three earnouts that were entered into at closing. The fair value of $1.6 million has been determined using a scenario-based method which indicated partial achievement of the criteria over the three years .

Ideanomics will receive exclusive sales and distribution rights for PEA charging infrastructure products and solutions in North America and CEO Alf Poor will join PEA’s Board of Directors Cybersecurity Incident The Company’s real estate services subsidiary, Timios, experienced a systems outage that was caused by a cybersecurity incident. Timios has engaged leading forensic information technology firms and legal counsel to assist its investigation into the incident and is working around the clock to get its system back up as quickly as possible. Although Timios is actively managing this cybersecurity incident, it has caused and may continue to cause a delay or disruption to parts of Timios’ business, including its ability to perform its mortgage title, closing and escrow services offerings. The Company is in the early stages of assessing the financial impact of the incident. Based on the information currently known, the Company is unable to predict at this time whether revenues will be materially impacted by this attack. Equity Offering On August 12, 2021, the Company entered into a Controlled Equity Offering Sales Agreement (the “Agreement”) with Cantor Fitzgerald & Co. (the “Agent”). In accordance with the terms of the Agreement, the Company may offer and sell from time to time through or to the Agent, as sales agent or principal, the Company’s common stock having an aggregate offering price of up to $350.0 million (the “Placement Shares.”) The Placement Shares will be offered and sold pursuant to the Company’s shelf registration statement on Form S-3 (Registration No. 333- 252230) and the related base prospectus included in the registration statement, as supplemented by the prospectus supplement dated August 12, 2021.

Nature of Operations and Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments of a normal recurring nature that are necessary for a fair presentation of the results for the interim periods presented. All significant intercompany transactions and balances are eliminated in consolidation. However, the results of operations included in such financial statements may not necessary be indicative of annual results. The Company uses the same accounting policies in preparing quarterly and annual financial statements. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the Securities and Exchange Commission (“SEC”) on March 31, 2021 (“2020 Form 10-K.”)
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as the related disclosure of contingent assets and liabilities. Actual results could differ from those estimates. On an ongoing basis, management evaluates the Company’s estimates, including those related to the bad debt allowance, variable consideration, fair values of financial instruments, intangible assets (including digital currencies) and goodwill, useful lives of intangible assets and property and equipment, asset retirement obligations, income taxes, and contingent liabilities, among others. The Company bases its estimates on assumptions, both historical and forward looking, that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
Immaterial Revision to Prior Period	Immaterial Revision to Prior Period The Company determined that a legal agreement the Company entered into whereby the Company took possession of a property in Qingdao, China for no consideration was incorrectly accounted for as a lease in accordance with ASC 842, Leases however, the Company has revised its condensed consolidated financial statements to properly account for this transaction. The adjustment to the condensed consolidated balance sheet as of December 31, 2020 is, as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Account December 31, ​ ​ December 31, ​ ​ 2020 ​ ​ ​ ​ 2020 ​ ​ (As Reported) ​ Adjustment ​ (As Revised) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Operating lease right of use assets ​ $ 7,117 ​ $ (6,962) ​ $ 155 Other non-current assets ​ 516 ​ 6,962 ​ 7,478 Current portion of lease liabilities ​ 430 ​ (315) ​ 115 Other current liabilities ​ 1,920 ​ 315 ​ 2,235 Operating lease liability – long-term ​ 6,759 ​ (6,740) ​ 19 Other long-term liabilities ​ 535 ​ 6,740 ​ 7,275 ​ See Note 2 for adjustments for this matter as of and for the period ended June 30, 2021.
Inventory	Inventory Inventories, which include the costs of material, labor and overhead, are stated at the lower of cost or net realizable value, with cost generally computed on a first-in, first-out (“FIFO”) basis. Estimated losses from obsolete and slow-moving inventories are recorded to reduce inventory values to their estimated net realizable value and are charged to costs of revenue. At the point of loss recognition, a new cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in a recovery in carrying value. The composition of inventory is as follows (in thousands): ​ ​ ​ ​ ​ June 30, 2021 Raw materials ​ $ 736 Work in progress ​ 39 Finished goods ​ 2,798 Total ​ $ 3,573
Revenue	Title Revenue Premiums from title insurance policies written by independent agencies are recognized net of commission costs when the policies are reported to Timios and not before the effective date of the policy. Regulation of title insurance rates varies by state. Premiums are charged to customers based on rates predetermined in coordination with each states’ respective Department of Insurance. Closing Revenue A closing or escrow is a transaction pursuant to an agreement of a buyer, seller, borrower, or lender wherein an impartial third-party, such as Timios, acts in a fiduciary capacity on behalf of the parties in accordance with the terms of such agreement in order to accomplish the directions stated therein. Services provided include, among others, acting as escrow or other fiduciary agent, obtaining releases, and conducting the actual closing or settlement. Closing and escrow fees are recognized upon closing of the escrow, which is generally at the same time of the closing of the related real estate transaction. Appraisal Revenue Revenue from appraisal services are primarily related to establishing the ownership, legal status and valuation of the property in a real estate transaction. In these cases, Timios does not issue a title insurance policy or perform duties of an escrow agent. Revenues from these services are recognized upon delivery of the service to the customer. Title Plant Title plant consists of costs incurred to construct the title plant and to obtain, organize and summarize historical information for Glenn County title searches. These costs were capitalized until such time as the plant was deemed operational to conduct title searches and issue title insurance policies. Management has determined that the title plant has been properly maintained, has an indeterminable life, and in accordance with Accounting Standards Codification (“ASC”) Topic 950, Financial Services – Title Plant Software Development Costs Software developed or obtained for internal use in accordance with ASC 350-40, Internal-Use Software Escrow and Trust Deposits In providing escrow services, Timios holds funds for others in a fiduciary capacity, pending completion of real estate transactions. A separate, self-balancing set of accounting records is maintained by Timios to record escrow transactions. Escrow trust funds held for others are not Timios’s and, therefore, are excluded from the accompanying condensed consolidated balance sheet, however, Timios remains contingently liable for the disposition of these deposits. Escrow trust balances at June 30, 2021 were $41.1 million. It is a common industry practice for financial institutions where escrow funds are deposited to either reimburse or to directly provide for certain costs related to the delivery of escrow services. Timios follows the practice of non-recognition of costs borne by the financial institution where escrow funds are deposited. Revenue For product sales, the acquired EV entities consider practical and contractual limitations in determining whether there is an alternative use for the product. For example, long-term design and build contracts are typically highly customized to a customer’s specifications. For contracts with no alternative use and an enforceable right to payment for work performed to date, including a reasonable profit if the contract were terminated at the customer’s convenience for reason other than nonperformance, the acquired EV entities recognize revenue over time. All other product sales are recognized at a point in time. For contracts recognized over time, the acquired EV entities use the cost-to-total cost method or the units of delivery method, depending on the nature of the contract, including length of production time. For contracts recognized at a point in time, the acquired EV entities recognize revenue when control passes to the customer, which is generally based on shipping terms that address when title and risk and rewards pass to the customer. However, the acquired EV entities also consider certain customer acceptance provisions as certain contracts with customers include installation, testing, certification or other acceptance provisions. In instances where contractual terms include a provision for customer acceptance, the acquired EV entities consider whether they have previously demonstrated that the product meets objective criteria specified by either the seller or customer in assessing whether control has passed to the customer. For service contracts, the acquired EV entities recognize revenue as the services are rendered if the customer is benefiting from the service as it is performed, or otherwise upon completion of the service. Separately priced extended warranties are recognized as a separate performance obligation over the warranty period. The transaction price in the acquired EV entities’ contracts consists of fixed consideration and the impact of variable consideration including returns, rebates and allowances, and penalties. Variable consideration is generally estimated using a probability-weighted approach based on historical experience, known trends, and current factors including market conditions and status of negotiations. For design and build contracts, the acquired entities may at times collect progress payments from the customer throughout the term of the contract, resulting in contract assets or liabilities depending on the timing of the payments. Contract assets consist of unbilled amounts when revenue recognized exceeds customer billings. Contract liabilities consist of advance payments and billings in excess of revenue recognized. Design and engineering costs for highly complex products to be sold under a long-term production-type contract are deferred and amortized in a manner consistent with revenue recognition of the related contract or anticipated contract. Other design and development costs are deferred only if there is a contractual guarantee for reimbursement. Costs to obtain a contract (e.g., commissions) for contracts greater than one year are deferred and amortized in a manner consistent with revenue recognition of the related contract.
Product Warranties	Product Warranties The acquired EV entities’ standard product warranty terms generally include post-sales support and repairs or replacement of a product at no additional charge for a specified period of time. Accruals for estimated expenses related to product warranties are made at the time revenue is recognized and are recorded as a component of costs of revenue. The acquired EV entities estimate the liability for warranty claims based on standard warranties, the historical frequency of claims and the cost to replace or repair products under warranty. Factors that influence the warranty liability include the number of units sold, the length of warranty term, historical and anticipated rates of warranty claims and the cost per claim. The warranty liability as of June 30, 2021 is $0.6 million and is included in “Other long-term liabilities” within the condensed consolidated balance sheet. The warranty liability has not changed substantially subsequent to WAVE’s acquisition.
Effects of COVID 19	Effects of COVID 19 Novel Coronavirus 2019 (“COVID-19”) is an infectious disease cause by severe acute respiratory syndrome coronavirus. The disease was first identified in December 2019 in Wuhan, the capital of China’s Hubei province, and has since spread globally, resulting in the ongoing COVID-19 pandemic. As of July 31, 2021, over 197.6 million cases had been reported across the globe, resulting in 4.2 million deaths. The spread of COVID-19 has caused significant disruption to society as a whole, including the workplace. The resulting impact to the global supply chain has disrupted most aspects of national and international commerce, with government-mandated social distancing measures imposing stay-at-home and work-from-home orders in almost every country. The effects of social distancing have shut down significant parts of the local, regional, national, and international economies, for limited or extended periods of time, with the exception of government designated essential services. In many parts of the world, stay-at-home and work-from-home orders were relaxed during the summer of 2020 as the effects of the Coronavirus appeared to lessen, and economic activity began to recover. However, commencing in the autumn and fall of 2020 and continuing, the U.S. as well as countries in Europe, South America and Asia began to experience an increase in new COVID-19 cases, and in some cases local, state, and national governments began to reinstate restrictive measures to stem the spread of the virus. The U.S. and other countries also experienced an increase in new COVID-19 cases after the fall and winter holiday season, with new, more infectious variants of COVID-19 identified. Various vaccines have been developed, with vaccinations programs in effect worldwide, though reaching acceptable levels of immunization against COVID-19 remains challenging at the local, regional and global level remains challenging. The future effects of the virus are difficult to predict, due to uncertainty about the course of the virus, different variants that may evolve, and the supply of the vaccine on a local, regional, and global basis, as well as the ability to implement vaccination programs in a short time frame. The Company does not anticipate significant adverse effects on its operations’ revenue as compared to its business plan in the near- or mid-term, although the future effects of COVID-19 may result in regional restrictive measures which may constrain the Company’s operations, and supply chain shortages of various materials may have a negative effect on our EV sales or production capacity in the longer-term. The Company’s Treeletrik business, which focuses on the sale of motorbikes in the ASEAN region, is experiencing disruption in its operations as a result the continued lockdowns in the region, which have adversely impacted its ability to fulfill committed orders.

The contractual period which required periodic remeasurement has expired, and therefore the Company will not remeasure this liability in the future. The fair value of DBOT contingent consideration as of June 30, 2021 was valued using the Black-Scholes Merton method. The Company issued 11.3 million shares during the six months ended June 30, 2020 and partially satisfied this liability. No shares have been issued in the six months ended June 30, 2021. 2 This represents the liability incurred in connection with the acquisition of Tree Technology shares during the fourth quarter of 2019 and as subsequently remeasured as of June 30, 2021. The fair value of the Tree Technology contingent consideration was valued using a scenario-based method which incorporates various estimates, including projected gross revenue for the periods, probability estimates, discount rates and other factors. 3 This represents the liability incurred in connection with the acquisition of WAVE. The liability represents the combination of the contingent shares and the earnout. The contingent shares are the remaining shares to be issued contingent on the receipt of certain customer consents as disclosed in Note 6. The fair value of this contingent consideration was valued using a scenario-based method that indicated based on the probabilities that 100% of the consents will be received. The earnout liability is dependent on WAVE achieving certain revenue and gross profit margin criteria in 2021, 2022 and cumulatively 2021 and 2022. The fair value of zero has been determined using a scenario-based method which indicated that none of the criteria are likely to be achieved. 4 This represents the liability incurred in connection with the acquisition of Solectrac. The liability represents the fair value of the three earnouts that were entered into at closing. The fair value of $1.6 million has been determined using a scenario-based method which indicated partial achievement of the criteria over the three years .
