Nature of the Business

Nature of the Business
Nature of the Business	1. Nature of the Business Wejo Limited (“the Company” or “Wejo”) is a private limited liability company incorporated under the laws of England and Wales on December 13, 2013. Wejo is an early leader in the connected vehicle data market. Connected vehicles contain hundreds of data sensors, emitting information such as location, speed, direction and events such as braking, temperature and weather conditions. This data creates intelligence, in near real- time and historically, that is unavailable from any other source. The Company ingests and standardizes this data, mainly in the United States and Europe at this time, through its proprietary data exchange platform (“Wejo ADEPT” or “ADEPT”). The Company’s products enable customers such as departments of transportation, retailers, construction firms and research departments to unlock unique insights about journeys, cities, electric vehicle usage, safety and more. Over the next two to three years, the Company expects to expand its platform to ingest data globally, and to expand into additional marketplaces as well as providing business insights to its Original Equipment Manufacturer (“OEM”) preferred partners. The Company is comprised of eight wholly-owned subsidiaries. The Company’s primary office is located in Manchester, England. In addition to its primary office, Wejo Concierge UK Ltd, and Rewardrive Ltd., are also located in the United Kingdom (the “U.K.”), Wejo EU is located in Ireland, Wejo Group Ltd. (“Wejo Group”) is located in Bermuda, and Wejo California Corp., Wejo Data Services Inc., Wejo Services Inc., and Wejo Inc. are located in the United States (the “U.S.”). Products and services The Company partners with the world’s leading automotive manufacturers to standardize connected car data through the Wejo ADEPT platform, including traffic intelligence, analysis of high frequency vehicle movements and analysis of common driving events and trends. For customers and marketplaces, the Company will provide insights, solutions and analytics through software and visualization tools available for license and subscription by its customers. Wejo ADEPT is a cloud-based data exchange platform that makes sharing and accessing vast volumes of connected car data simple by removing the barriers and maximizing the intrinsic value in car data for drivers, vehicle manufacturers and other adjacent businesses. The Wejo ADEPT platform interfaces with the electronic data within vehicles from manufacturers which have agreed to use the platform. This data can be utilized by the manufacturers as well as other private and public sector businesses in order to create advanced analysis, machine learning and rapid insights. The Wejo ADEPT platform also includes flexible implementation options and adaptable interfaces to ensure a successful and rapid roll out across territories. In addition, Wejo ADEPT’s compliance wrappers support legal and legislative assurance, including country, federal, state and local variations. Wejo ADEPT is hosted by cloud data centers, and as a function of this central hosting, the ADEPT platform operates in a multi-tenancy environment, that standardizes vehicle data. The end users of the Wejo ADEPT platform can only access data through a licensing agreement and do not have the ability to take possession of the software itself. The Company has two primary areas of service, Data Marketplace and Automotive Business Insight Solutions (SaaS). Each product line utilizes the Company’s exclusive, proprietary dataset that is derived from the vehicle sensors of the connected vehicles of its OEM partners. In the Data Marketplace, the Company offers licenses for the use of data and licenses software analytical tools that interpret the dataset to customers. In the Automotive Business Insight Solutions (SaaS) business, the Company offers licenses of software analytical tools to OEMs and their direct ecosystem (suppliers, distributors, partners) that interpret the dataset to improve the management of their operations and support the improvement of the automotive customers’ experience. Going Concern In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), the Company has evaluated whether there are conditions and 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 condensed consolidated financial statements are issued. As is common to early-stage companies with limited operating histories, the Company is subject to risks and uncertainties such as its ability to influence the connected vehicle market; invest in technology, resources and new business capabilities; maintain and grow the customer base; secure additional capital to support the investments needed for its anticipated growth; comply with governing laws and regulations; and other risks and uncertainties. To manage these risks and uncertainties while growing as expected, the Company will make significant investments and will therefore need to raise substantial capital during its loss- making period. The Company has incurred operating losses and negative cash flows from operations since inception. The Company expects to continue to incur losses and negative cashflows from operations for the foreseeable future as it continues to develop its product offerings. As the Company makes investments to increase the markets and customers it serves, the operating losses are expected to increase until the Company reaches the necessary scale to generate cash profits from operations. The Company has historically relied on private equity offerings and debt financings, and to a limited extent revenue from customers to fund its operations. As of September 30, 2021 and December 31, 2020, the Company had an accumulated deficit of $308.7 million and $146.8 million, respectively. Net losses incurred for the nine months ended September 30, 2021 and year ended December 31, 2020 amounted to $161.9 As of September 30, 2021, the Company had cash of $8.6 million. In the fourth quarter of 2021, the Company issued further notes in a principal amount of $7.5 million under the Loan Note Instrument. In November 2021, the Company completed the business combination (see Note 15), which raised $178.8 million. This consisted of $230.0 million cash received in the trust, less redemptions of $132.8 million, and $128.5 million, through a Private Investment in Public Entity (“PIPE”) investment, net of expenses of $46.9 million. The $178.8 million in proceeds were offset by a payment of $75.0 million from the Company to Apollo as stipulated in the Forward Purchase Transaction (see Note 15). After considering the fund raising described above, the Company believes that it has sufficient cash on hand to support the Company’s operating expenses and capital requirements through at least the next twelve months from the date of issuance of these condensed consolidated financial statements. Restatement of Previously Issued Financial Statements Subsequent to the filing of the Original Form 10-Q, management completed a more detailed review of the Company’s results in preparation for a business update with investors and determined that certain costs were incorrectly classified which has led to the Restatement. The Restatement reflects the correction of the allocation of certain employee, post retirement and other related expenses such as facilities, information technology and other costs based upon departmental function. Wejo Group determined that the line items impacted in the unaudited condensed consolidated statements of operations and comprehensive loss were: Cost of revenue, Technology and development, Sales and marketing, and General and administrative expenses and that a correction of the errors in the foregoing line items is required.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of Wejo Limited and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated upon consolidation. Unaudited Condensed Consolidated Financial Statements The accompanying condensed consolidated balance sheets as of September 30, 2021, and the condensed consolidated statements of operations and comprehensive loss for the three and nine months ended September 30, 2021 and 2020, condensed consolidated statements of shareholders’ deficit for the three and nine months ended September 30, 2021 and 2020, and statements of cash flows for the nine months ended September 30, 2021 and 2020 are unaudited. The condensed consolidated interim financial statements have been prepared on the same basis as the audited annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary for the fair presentation of the Company’s financial position at September 30, 2021 and the results of its operations for the three and nine months ended September 30, 2021 and 2020 and its cash flows for the nine months ended September 30, 2021 and 2020. The financial data and other information disclosed in these notes related to the three and nine months ended September 30, 2021 and 2020 are also unaudited. The results for the nine months ended September 30, 2021 are not necessarily indicative of results to be expected for the full year or for any other subsequent interim period. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes included elsewhere in the prospectus filed on October 18, 2021. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and accompanying notes. Significant estimates and assumptions reflected in these unaudited condensed consolidated financial statements and accompanying notes include, but are not limited to, the fair value of the Company’s ordinary shares, derivative liability, advanced subscription agreements, income taxes, software development costs and the estimate of useful lives with respect to developed software. Although the Company believes that its estimates, assumptions, and judgments are reasonable, they are based upon information available at the time. Actual results may differ significantly from these estimates under different assumptions, judgments or conditions. Net Loss per Share The Company has reported losses since inception and has computed basic net loss per share attributable to ordinary shareholders by dividing net loss attributable to ordinary shareholders by the weighted-average number of ordinary shares outstanding for the period, without consideration for potentially dilutive securities. The Company computes diluted net loss per ordinary share after giving consideration to all potentially dilutive ordinary shares, including warrants and share options, outstanding during the period determined using the treasury-share and if-converted methods, except where the effect of including such securities would be antidilutive. Because the Company has reported net losses since inception, these potential ordinary shares have been anti-dilutive and basic and diluted loss per share were the same for all periods presented. Recently Issued Accounting Pronouncements Not Yet Adopted In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU 2016-02, Leases In June 2019, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments In December 2019, the FASB issued ASU 2019-12, Income Taxes In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options

Revenue from Customers

Revenue from Customers
Revenue from Customers	5. Revenue from Customers Connected Vehicle Data Marketplace The Company’s customer agreements include one or a combination of the following contractual promises for a fixed contractual fee: i) the supply of specified connected vehicle data and derived insights through the Wejo ADEPT platform made available via a secured access to the Wejo ADEPT platform or via a web-based portal; ii) the granting of a nontransferable license to use the specified data in the manner described in each customer agreement; and iii) Wejo ADEPT Platform set up and connectivity services. The Company assessed the customer agreements under Accounting Standards Codification (“ASC”) 606 and determined that the above contractual promises collectively represent one distinct performance obligation. The transaction price is comprised of the contractual fixed fee specified in each customer agreement and is allocated to the single performance obligation. The Company recognizes revenue when the performance obligation is satisfied through the fulfillment of the contractual promises. The performance obligation is generally fulfilled by the Company providing access to the specified data either throughout the duration of each customer agreement’s contractual term or upon delivery of a one-time batch of historic data. The Company may deliver data and the license without supplying connectivity services. As such, the Company generally recognizes revenue for customers with a contractual agreement to provide data over a period ratably over the term of the contract which is typically one year. The Company recognizes revenue for historic batches of data to the customer upon delivery of such data. Standard payment terms are 14 days from the date of the invoice which is typically sent to the customer monthly or upon delivery of the one-time historic batch of data. In arrangements where another party (i.e. OEMs) is involved in providing specified services to a customer, the Company evaluates whether it is the principal or agent. In this evaluation, the Company considers if it obtains control of the specified goods or services before they are transferred to the customer, as well as other indicators such as the party primarily responsible for fulfillment, and discretion in establishing price. Pursuant to the terms of the Data Sharing Agreements, certain rights retained by the OEMs over the connected vehicle data being supplied to the customers were determined to provide the OEMs with control over the data and the Company has determined it acts as the agent in this arrangement and recognizes revenue on a net basis. During the three and nine months ended September 30, 2021 and 2020, the Company has recognized a reduction of revenue of $0.8 million, $2.5 million, $0.6 million and $1.6 million, respectively, arising from revenue sharing with the Company’s OEM partners. During the three months ended September 30, 2021 and 2020, the Company had two customers that individually generated 10.0% or more of the Company’s revenue for the respective period. The two significant customers generated 21.0% and 18.8% of the Company’s gross revenue during the three months ended September 30, 2021. For the three months ended September 30, 2020, the Company has two customers that generated 19.8% and 18.7% of the Company’s revenue. In addition, the revenue recognized over time and at a point in time was approximately 40% and 60% during the three months ended September 30, 2021 and 70% and 30%, during the three months ended September 30, 2020. During the nine months ended September 30, 2021 and 2020, the Company had two customers that individually generated 10.0% or more of the Company’s revenue for the respective period. One of the two significant customers during the nine months ended September 30, 2021 was also a significant customer during the nine months ended September 30, 2020. The two significant customers in the nine months ended September 30, 2021 generated 17.0% and 12.7% of the Company’s gross revenue during the nine months ended September 30, 2021. The two significant customers in the nine months ended September 30, 2020 generated 23.0% and 12.6% of the Company’s revenue. In addition, the revenue recognized over time and at a point in time was approximately 56% and 44% during the nine months ended September 30, 2021 and 75% and 25%, during the nine months ended September 30, 2020. During the three and nine months ended September 30, 2020, the Company earned the majority of its revenue from the Data Marketplace product line as Automotive Business Insight Solutions (SaaS) revenue was immaterial and earned 100%of its revenue within the U.S. For the three and nine months ended September 30, 2021, the Company earned the majority of its revenue from the Data Marketplace product line as Automotive Business Insight Solutions (SaaS) revenue was immaterial and earned approximately 98% and 97% of its revenue within the U.S., respectively. The country in which the revenue is generated is based on the address of the ultimate customer utilizing the data provided.

The Ordinary, A Ordinary, and B Ordinary shares are separate classes of shares but rank pari passu in all respects. No A Ordinary shares are outstanding from an accounting perspective as of September 30, 2021 or December 31, 2020. See Note 7 for outstanding options to purchase A Ordinary shares.

There were no issuances of warrants for the nine months ended September 30, 2021 and 2020. As of September 30, 2021 and December 31, 2020 there were 841,511 outstanding warrants to purchase the Company’s ordinary shares, of which 726,678 were exercisable as of each year end and 114,833 are only exercisable upon an Exercisable Event (see Note 7). The 726,678 warrants exercisable at each period end and the 114,833 warrants exercisable upon an Exercisable Event have a weighted-average exercise price of $9.82 and $9.66 per warrant, respectively. All outstanding warrants were exercised and exchanged for 613,965 shares of the Company and were ultimately exchanged for 1,967,193 shares of Wejo Group as part of the business combination (see Note 15).

Share-Based Compensation
Share-Based Compensation	7. Share-Based Compensation Enterprise Management Incentive Plan In 2013, the Company established the Enterprise Management Incentive Plan (the “EMI Plan”) in order to issue equity awards to its employees and directors of the Company in the form of options to purchase either Ordinary or A Ordinary shares as a means to secure the benefits arising from capital share ownership. EMI Plans are tax-advantaged employee share option schemes designed for small and medium-sized companies in the U.K. The purposes of the EMI Plan are to promote the long-term financial interests and growth by attracting, retaining and motivating participants by means of growth-related equity incentives to achieve long-term goals and to align the interests of the participants under the EMI Plan with those of the shareholders of the Company through opportunities for share-ownership in the Company. The EMI Plan is administered by the Board and each option is set forth in writing in an option agreement, duly executed by the Company and, to the extent required by law or requested by the Company, by the participant. The exercise prices, vesting and other restrictions are determined by the Board, except that the exercise price per share must be at least equal to the lesser of the fair market value (“FMV”) per share of Ordinary share on the option grant date or £0.00001. Shares reserved for issuance that are cancelled or terminated without having been exercised will again be available for issuance under the EMI Plan. As of December 31, 2018, the Company failed to meet the EMI gross assets requirement as its gross assets exceeded £30.0 million ($40.4 million at September 30, 2021), and therefore, no longer qualified to issue options under the EMI Plan. Under the EMI Plan, the Company granted Employee Share Options to purchase A Ordinary shares and Ordinary shares that only vest and become exercisable upon (i) the sale of the whole business or assets of the Company; (ii) a takeover of the Company by an outside source; or (iii) the first occasion on which ordinary shares in the capital of the Company are permitted to be traded or dealt in on a relevant market (“Exercisable Event”). These events were not determined to be probable of occurring as of September 30, 2021. As such, the Company has not recognized any compensation costs related to the awards. A summary of the changes in the Company’s Employee Share Options issued under the EMI Plan during the nine months ended September 30, 2021 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Average ​ ​ ​ ​ ​ ​ ​ Weighted ​ Remaining ​ ​ ​ ​ ​ Number of ​ Average Strike ​ Contractual ​ Aggregate ​ ​ Units ​ Price ​ Term ​ Intrinsic Value Option to purchase A Ordinary Shares Outstanding per Unit (in years) (in thousands) Outstanding at December 31, 2020 710,431 ​ $ 0.20 7.7 ​ $ 11,910 Granted — ​ $ — ​ Exercised — ​ $ — ​ Forfeited (6,000) ​ $ 0.20 ​ Outstanding at September 30, 2021 704,431 ​ $ 0.20 7.0 ​ $ 27,389 Exercisable at September 30, 2021 — ​ $ — — ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Average ​ ​ ​ ​ ​ ​ ​ Weighted ​ Remaining ​ ​ ​ ​ ​ Number of ​ Average Strike ​ Contractual ​ Aggregate ​ ​ Units ​ Price ​ Term ​ Intrinsic Value Option to purchase Ordinary Shares Outstanding per Unit (in years) (in thousands) Outstanding at December 31, 2020 9,724 ​ $ 15.26 2.0 ​ $ 73 Granted — ​ $ — ​ Exercised — ​ $ — ​ Forfeited — ​ $ — ​ Outstanding at September 30, 2021 9,724 ​ $ 15.26 2.0 ​ $ 260 Exercisable at September 30, 2021 — ​ $ — — ​ $ — ​ The Company did not grant any options under the EMI Plan during the three and nine months ended September 30, 2021 and 2020.

The options issued under the Articles of Association also only become exercisable upon an Exercisable Event, but unlike the options issued under the EMI Plan which expire 10 years after issuance, the options issued under the Articles of Association do not have an expiration date. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Number of ​ Weighted Average ​ Aggregate ​ ​ Units ​ Strike Price ​ Intrinsic Value Option to purchase A Ordinary Shares Outstanding per Unit (in thousands) Outstanding at December 31, 2020 5,357,679 ​ $ 0.27 ​ $ 64,431 Granted — ​ $ — ​ Exercised — ​ $ — ​ Forfeited (16,047) ​ $ 0.24 ​ Outstanding at September 30, 2021 5,341,632 ​ $ 0.27 ​ $ 178,972 Exercisable at September 30, 2021 — ​ $ — ​ $ — ​ The Company did not grant any options under the Articles of Association during the three and nine months ended September 30, 2021 and 2020.

The unrecognized compensation cost will be recognized upon an Exercisable Event becoming probable of occurring. All outstanding options were exercised and exchanged for 702,839 shares of the Company and were ultimately converted into 2,111,666 Wejo Group shares as part of the business combination (see Note 15).

Advanced Subscription Agreements
Advanced Subscription Agreements	8. Advanced Subscription Agreements Between September 2019 and March 2020, the Company entered into ASAs with future investors resulting in gross proceeds of £5.6 million (approximately $7.1 million), of which £0.3 million (approximately $0.3 million) was received during the nine months ended September 30, 2020. The Company elected to account for the ASAs using the fair value option, pursuant to which, the associated liability was recorded at fair value and subsequently remeasured to fair value at each reporting date. During the three and nine months ended September 30, 2021 and 2020, the Company recognized a gain of $0.3 million, a loss of $6.5 million, a loss of $0.7 million and a gain of $0.7 million, respectively, in the unaudited condensed consolidated statements of operations and comprehensive loss related to the change in the estimated fair value of the ASAs (see Note 3). The holders of the ASAs have the following rights: Automatic Conversion Feature Upon issuance of the ASAs, the occurrence of either a Series C round financing or share sale triggering a change of control, the principal will automatically convert at an amount equal to 75.0% of the share price paid by the investors in the financing, but not exceed the valuation cap of £26.45 per share ($36.78 per share at July 31, 2021) for certain investors who participated in the ASA. If neither the Series C round financing or any share sale triggering a change of control has occurred by December 31, 2020 (the “Long Stop Date”), the principal will automatically convert into ordinary shares of the Company at a prevailing price of £14.54 per ordinary share ($20.22 per share at July 31, 2021). In 2020, under the amendment to the ASAs, certain holders agreed to extend the Long Stop Date to July 31, 2021. On July 31, 2021, all outstanding ASAs converted into 328,730 ordinary shares of the Company based on the amended Long Stop Date and were ultimately converted into 1,053,273 shares of Wejo Group as part of the business combination (see Note 15).

Between January and June 2021, the Company issued additional convertible loans with an aggregate principal amount of $21.1 million (collectively with the 2020 issuances, the “Loans”), $4.8 million of which was issued through the conversion of accounts payable and recognition of prepaid revenue share costs (see Note 14). The Loans bear interest at a fixed rate of 8.0% per annum until the earlier of July 21, 2023 (the “Maturity Date”) or the date on which they are redeemed or converted. Upon the Maturity Date, the Loans convert into the most senior class of shares in the Company at a price per share equal to 60.0% of the lowest price per share paid by an investor in the then most recent equity financing, subject to cap on the price per share at which the Loans convert into shares in the Company, determined by dividing a valuation cap for the Company of £206.5 million by the number of shares comprising the Company’s fully diluted share capital at the relevant time (the “Valuation Cap”). In the event of an equity financing round, whereby the Company raises an amount equal to at least the aggregate amount of the Loans received by the Company at the time of such financing round, in newly committed capital prior to the Maturity Date from one or a series of related issuances of shares to investors (“Qualified Financing”), all outstanding principal and accrued interest will convert into the most senior class of shares with identical rights and preferences as attached to, and with the same obligations as, the securities issued to the investors in the Qualified Financing (including any warrants, options, bonus shares or other economic rights made available to investors in such Qualified Financing) at a price per share equal to 60.0% of the lowest price per share paid by an investor in the Qualified Financing, subject to the Valuation Cap. In the event of an equity financing round that is not a Qualified Financing (“Non-Qualified Financing”), holders of the majority of the Loans then outstanding (excluding the single largest holder of the Loans) have the option to convert all the outstanding principal and unpaid interest of the Loans into the most senior class of shares with identical rights and preferences as attached to, and with the same obligations as, the securities issued to the investors in the Non-Qualified Financing (including any warrants, options, bonus shares or other economic rights made available to investors in such Non-Qualified Financing) at a price per share equal to 60.0% of the lowest price per share paid by an investor in the Non-Qualified Financing, subject to the Valuation Cap. Upon a change of control in the Company, sale of all or substantially all of the group’s undertaking and assets, or an admission of all or any of the Company’s shares or securities to trading on certain exchanges (each, an “Exit”), the Loans will convert into the most senior class of shares in the Company in issue at the time of the Exit where: (i) a lender would receive a greater amount as cash consideration on an Exit for the sale of the shares that are issued to it on conversion of its Loan than it would otherwise receive had it been repaid its Loan with a redemption premium equal to 100% of the principal amount outstanding (the “Redemption Premium”); or (ii) the Lenders would receive any non-cash consideration for the sale of such shares (unless the single largest holder of the Loans (in respect of its Loan) or a majority the other lenders (in respect of the remaining loans) elect to redeem their loans), in each case at a price per share equal to 60.0% of the lowest price per share paid by an investor in the then most recent equity financing, subject to the Valuation Cap. Upon an event of default, including failure to comply with the Company’s payment and other obligations under the Loans, the outstanding principal and accrued interest, together with the Redemption Premium, becomes due and payable. Rather than allow their Loans to convert on whichever applies of: (i) the Maturity Date, (ii) the date of a Qualified Financing, (iii) Non-Qualified Financing, or (iii) an Exit, a majority of the lenders (in respect of the remaining loans) may elect to receive repayment of their Loans together with the Redemption Premium. The Loans are not voluntarily redeemable or prepayable at the election of the Company — redemption or prepayment of the Loans requires the prior written consent of each Lender. The Company assessed whether an immediate beneficial conversion feature (“BCF”) existed with regards to the conversion option upon maturity at each issuance of the Loans. A beneficial conversion feature exists when convertible instruments are issued with an initial “effective conversion price” that is less than the fair value of the underlying share. The Company determined that there were BCFs associated with such conversion feature upon issuance of the January 2021 Loans and April 2021 Loans, respectively, and recorded total BCF of $27.2 million to additional paid-in capital on the condensed consolidated balance sheet, representing the intrinsic value of the in-the-money portion of the conversion option upon maturity, with an offsetting reduction to the carrying amount of the Loans as a debt discount upon issuance. The Company concluded that the conversions in the event of a Qualified Financing and Non-Qualified Financing represented redemption features and, along with the redemption features upon an Exit and an event of default, each met the definition of embedded derivative that was required to be accounted for as a separate unit of accounting (see Note 3). The Company recorded derivative liabilities of $36.9 million in the condensed consolidated balance sheets for the issuance-date fair value of the embedded derivatives associated with the January 2021 Loans and April 2021 Loans. The offsetting debt discount is limited to the proceeds allocated to the Loans. The aggregate value of the BCFs, issuance-date fair value of the derivative liabilities, and debt issuance costs associated with the January 2021 Loans and April 2021 Loans exceeded its allocated proceeds by $44.2 million. As a result, the carrying value of the January 2021 Loans and April 2021 Loans were reduced to zero and a loss on issuance of $44.2 million was recorded on the condensed consolidated statements of operations and comprehensive loss for the nine months ended September 30, 2021. No loss on issuance was recognized during the three months ended September 30, 2021 and 2020. The discounted carrying amount of the Loans is accreted to the mandatory redemption amount, equal to the aggregate of the principal, accrued interest, and Redemption Premium, through the stated redemption date of July 21, 2023. As of September 30, 2021 and December 31, 2020, the fair value of the derivative liability was $126.9 million and $35.0 million, respectively. During the three and nine months ended September 30, 2021 and 2020, the Company recognized a loss of $1.6 million, $58.3 million, $3.1 million and $3.1 million on the condensed consolidated statements of operations and comprehensive loss related to the change in the estimated fair value of the derivative liability, respectively. As of September 30, 2021 and December 31, 2020, the value of the Loans, measured at amortized cost, was $8.8 million and $6.1 million, respectively, inclusive of a debt discount of $38.1 million and $20.7 million, respectively, and was classified as a long-term liability on the Company’s unaudited condensed consolidated balance sheets. The accretion of amortized cost of $1.1 million, $2.9 million, $0.4 million and $0.4 million was recorded on the condensed consolidated statements of operations and comprehensive loss during the three and nine months ended September 30, 2021 and 2020, respectively. All outstanding Loans were converted for 3,264,741 shares in the Company and were ultimately converted into 10,460,460 shares of Wejo Group as part of the business combination (see Note 15).

Long term debt, net of unamortized debt discount and debt issuance costs	10. Long-term debt, net of unamortized debt discount and debt issuance costs In April 2021, the Company entered into a loan note instrument agreement in which it issued fixed rate secured loan notes in a principal amount of $21.5 million that bears interest at a fixed per annum rate of 9.2% until its maturity date in April 2024. In April 2021, the Company used $10.8 million of the proceeds to repay its outstanding debt balance and fees owed to General Motors (“GM”) under the credit facility (see Note 13). The maturity date is three years after the issuance date. The maturity may be extended for a one-year period if the Company and the noteholders holding at least 66.66% of the loan notes outstanding deliver written notice to noteholders for extension. The principal on the loan notes will be paid at maturity, or upon an early redemption. The first interest payment of $2.0 million was due no later than six business days after the issue date for the period commencing on the issue date up to but excluding the first anniversary of the issue date. The first-year prepaid interest payment was treated as a discount to the debt. Thereafter, interest payments are due monthly until the loan notes are repaid. Pursuant to an amendment and consent agreement dated July 23, 2021, the Company has the option to issue further notes in a principal amount of up to $21.5 million with the consent of the majority noteholders. On July 26, 2021, the Company issued an additional $10.0 million of fixed rate secured loan notes that bears interest at a fixed per annum rate of 9.2% until their maturity date on April 21, 2024. This was treated as a modification to the long-term debt. The principal on the loan notes will be paid at maturity, or upon an early redemption. The first-year prepaid interest payment was treated as a discount to the debt. Thereafter, interest payments are due monthly until the loan notes are repaid. The first interest payment of $1.0 million was due no later than six business days after the issue date for the period commencing on the issue date up to but excluding the first anniversary of the issue date. As of September 30, 2021, the carrying value of the loan notes consisted of $31.5 million principal outstanding, less the unamortized debt discount of approximately $4.5 million and the unamortized debt issuance costs of approximately $0.7 million. The debt discount and the debt issuance costs are being accreted to interest expense through the remaining term of the modified debt agreement using the interest method. Interest expense relating to the term loan for the three and nine months ended September 30, 2021 was $0.8 million and $1.3 million, respectively. Interest expense is calculated using the effective interest method and is inclusive of non-cash amortization of capitalized loan costs. At September 30, 2021, the effective interest rate was 14.65% . The Company’s scheduled future principal payments for the loan notes are as follows (in thousands): ​ ​ ​ ​ Year Ended December 31, ​ ​ ​ 2024 ​ $ 31,500 Less: unamortized discount and issuance costs ​ (5,187) Carrying value of long-term debt ​ $ 26,313 ​

Therefore, the weighted-average number of ordinary shares outstanding used to calculate both basic and diluted net loss per share attributable to ordinary shareholders is the same. The following potentially dilutive securities have been excluded from the calculation of diluted net loss per share due to their anti-dilutive effect: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended September 30, ​ Nine Months Ended September 30, ​ 2021 2020 2021 2020 Options to purchase A ordinary shares 6,046,063 ​ 2,926,735 ​ 6,046,063 ​ 2,926,735 Options to purchase ordinary shares 9,724 ​ 27,574 ​ 9,724 ​ 27,574 Warrants to purchase ordinary shares 841,511 ​ 841,511 ​ 841,511 ​ 841,511 Total 6,897,298 ​ 3,795,820 ​ 6,897,298 ​ 3,795,820 ​ The Company also had convertible loans outstanding as of September 30, 2021, each of which could obligate the Company to issue ordinary shares upon the occurrence of various future events at prices and in amounts that are not determinable until the occurrence of those future events. Because the necessary conditions for the conversion of these instruments had not been satisfied during the three and nine months ended September 30, 2021, the Company has excluded these instruments from the table above and the calculation of diluted net loss per share.

Legal Proceedings From time to time, the Company may be a party to litigation or subject to claims incident to the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on its business. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors. The Company records accruals for loss contingencies associated with these legal matters when it is probable that a liability will be incurred, and the amount of the loss can be reasonably estimated. In January 2021, the Company settled a proceeding in which it was obligated to pay $4.0 million in connection with a license agreement. This amount was recorded in accrued liabilities during the year ended December 31, 2019 when the claim was issued and deemed probable. The claim was covered under the Company’s insurance policy and the Company has recorded a receivable in other assets on the unaudited condensed consolidated balance sheets related to the insurance receivable of $4.0 million as of December 31, 2020. In April 2021, Arma Partners LLP (“Arma”), filed a lawsuit against the Company in the Royal Courts of Justice, London, England. In the lawsuit Arma claim a declaration from the Court that Arma is entitled to remuneration arising from a successful acquisition of the Company, in the event it occurs. Arma’s claim is disputed and is being defended in its entirety. The Company is unable to estimate what, if any, liability may result from this litigation. The Company does not believe there are any other pending legal proceedings that will have a material impact on the Company’s unaudited condensed consolidated balance sheet or unaudited condensed consolidated statement of operations and comprehensive loss and did not have contingency reserves established for any liabilities as of September 30, 2021 and December 31, 2020.

All intercompany accounts and transactions have been eliminated upon consolidation.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and accompanying notes. Significant estimates and assumptions reflected in these unaudited condensed consolidated financial statements and accompanying notes include, but are not limited to, the fair value of the Company’s ordinary shares, derivative liability, advanced subscription agreements, income taxes, software development costs and the estimate of useful lives with respect to developed software. Although the Company believes that its estimates, assumptions, and judgments are reasonable, they are based upon information available at the time. Actual results may differ significantly from these estimates under different assumptions, judgments or conditions.

The condensed consolidated interim financial statements have been prepared on the same basis as the audited annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary for the fair presentation of the Company’s financial position at September 30, 2021 and the results of its operations for the three and nine months ended September 30, 2021 and 2020 and its cash flows for the nine months ended September 30, 2021 and 2020. The financial data and other information disclosed in these notes related to the three and nine months ended September 30, 2021 and 2020 are also unaudited. The results for the nine months ended September 30, 2021 are not necessarily indicative of results to be expected for the full year or for any other subsequent interim period. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes included elsewhere in the prospectus filed on October 18, 2021.
Net Loss per Share	Net Loss per Share The Company has reported losses since inception and has computed basic net loss per share attributable to ordinary shareholders by dividing net loss attributable to ordinary shareholders by the weighted-average number of ordinary shares outstanding for the period, without consideration for potentially dilutive securities. The Company computes diluted net loss per ordinary share after giving consideration to all potentially dilutive ordinary shares, including warrants and share options, outstanding during the period determined using the treasury-share and if-converted methods, except where the effect of including such securities would be antidilutive. Because the Company has reported net losses since inception, these potential ordinary shares have been anti-dilutive and basic and diluted loss per share were the same for all periods presented.

Schedule of effect of the error correction on statement of operations and comprehensive loss	Subsequent to the filing of the Original Form 10-Q, management completed a more detailed review of the Company’s results in preparation for a business update with investors and determined that certain costs were incorrectly classified which has led to the Restatement. The Restatement reflects the correction of the allocation of certain employee, post retirement and other related expenses such as facilities, information technology and other costs based upon departmental function. Wejo Group determined that the line items impacted in the unaudited condensed consolidated statements of operations and comprehensive loss were: Cost of revenue, Technology and development, Sales and marketing, and General and administrative expenses and that a correction of the errors in the foregoing line items is required.
