Uber uses this same network, technology, operational excellence and product expertise to connect shippers with carriers in the freight industry. Uber is also developing technologies that will provide new solutions to solve everyday problems. Our technology is used around the world, principally in the United States (“U.S.”) and Canada, Latin America, Europe, the Middle East, Africa, and Asia (excluding China and Southeast Asia). Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The condensed consolidated balance sheet as of December 31, 2020 included herein was derived from the audited consolidated financial statements as of that date. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2020, included in our Annual Report on Form 10-K. The results for the interim periods are not necessarily indicative of results for the full year. In the opinion of management, these financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair statement of the financial position, results of operations, comprehensive loss, cash flows and the change in equity for the periods presented. There have been no changes to our significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on March 1, 2021 that have had a material impact on our condensed consolidated financial statements and related notes, except for an update reflecting the new accounting standard related to debt with conversion and other options. In March 2020, the World Health Organization declared the outbreak of the coronavirus disease COVID-19 (“COVID-19”) a pandemic. COVID-19 continues to impact market and economic conditions globally. The evolving nature of the COVID-19 pandemic and the extent of its impact across industries and geographies, including the duration of the spread of the outbreak and any resurgences of the outbreak or variants of the virus, continue to be uncertain and cannot be predicted. Basis of Consolidation Our condensed consolidated financial statements include the accounts of Uber Technologies, Inc. and entities consolidated under the variable interest and voting models. All intercompany balances and transactions have been eliminated. Refer to Note 14 – Variable Interest Entities for further information. Use of Estimates The preparation of our unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions, which affect the reported amounts in the financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions which management believes are reasonable under the circumstances. On an ongoing basis, management evaluates estimates, including, but not limited to: the incremental borrowing rate (“IBR”) applied in lease accounting; fair values of investments and other financial instruments (including the measurement of credit or impairment losses); useful lives of long-lived assets; fair value of acquired intangible assets and related impairment assessments; impairment of goodwill; stock-based compensation; income taxes and non-income tax reserves; certain deferred tax assets and tax liabilities; insurance reserves; and other contingent liabilities. These estimates are inherently subject to judgment and actual results could differ from those estimates. The level of uncertainties and volatility in the global financial markets and economies resulting from the pandemic as well as the uncertainties related to the impact of the pandemic on us and our investees' operations and financial performance means that these estimates may change in future periods, as new events occur and additional information is obtained. Certain Significant Risks and Uncertainties - COVID-19 Various governments continue to implement, lift, and in some regions reinstate restrictions, including business activities and travel restrictions. These restrictions have had an adverse impact on our business and operations by reducing, in particular, the global demand for Mobility offerings, while accelerating the growth of our Delivery offerings. COVID-19 has produced uncertainty around the world and it is not possible to predict the COVID-19 pandemic’s cumulative and ultimate impact on our future business operations, results of operations, financial position, liquidity, and cash flows. The extent of the impact of the pandemic on our business and financial results will depend largely on future developments, including the duration of the spread of the outbreak and any resurgences of the outbreak or variants of the virus, both globally and within the United States, the administration, adoption and efficacy of vaccines in the United States and internationally, the impact on capital, foreign currencies exchange and financial markets, governmental or regulatory orders that impact our business and whether the impacts may result in permanent changes to our end-users’ behavior, all of which are highly uncertain and cannot be predicted. Collateral Held by Insurer Collateral held by insurer represents funds held by James River Group companies (“James River”). These funds, previously held in a trust account, were withdrawn by James River during the fourth quarter of 2019 upon notice of cancellation of their insurance policies (primarily auto insurance policies) issued to one of our subsidiaries. As of December 31, 2020, the funds served as collateral for us and our subsidiary’s current and future claim settlement obligations under the indemnification agreements for these insurance policies as included in insurance reserves on the condensed consolidated balance sheet . Accordingly, the amount withdrawn is presented as collateral held by insurer on the condensed consolidated balance sheet a s of December 31, 2020. During the third quarter of 2021 , in connection with a legacy auto insurance transfer as described below, James River returned funds, previously presented as collateral held by insurer, to the trust account where the funds were previously held. Accordingly, the funds were reclassified from c ollateral held by insurer to non-current restricted cash and cash equivalents on our condensed consolidated balance sheet as of September 30, 2021. Legacy Auto Insurance Transfer On September 27, 2021, Aleka Insurance, Inc., our wholly-owned captive insurance subsidiary, entered into a Loss Portfolio Transfer Reinsurance Agreement (the “LPTA”) with James River effective July 1, 2021. Pursuant to the LPTA, our captive insurance subsidiary reinsured certain automobile liability insurance risks relating to activity on our platform between 2013 and 2019 in exchange for payment by James River to our captive insurance subsidiary of a premium in the amount of $345 million (“Premium”). Subsequent to the LPTA, we retain substantially all of the liabilities on these policies when taken together with previous risk transfer arrangements. In connection with the LPTA, claims currently administered by James River will be transferred to a third-party claims administrator for ongoing handling (the “Transferred Claims”) at our expense. The liabilities associated with the Transferred Claims were re-evaluated as of September 30, 2021, and adverse development was recognized on certain of those liabilities. During the third quarter of 2021, we recognized a $103 million charge in our condensed consolidated statements of operations consisting of the difference between the Premium and the assumed liabilities (including the cost of future claims administration), expenses associated with the LPTA, and the adverse development on the Transferred Claims. Recently Adopted Accounting Pronouncements In January 2020, the FASB issued ASU 2020-01, “Investments-Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815,” which clarifies the interaction of the accounting for equity investments under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. We adopted the new standard on January 1, 2021 on a prospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In August 2020, the FASB issued 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,” which reduced the number of models used to account for convertible instruments, amends the accounting for certain contracts in an entity’s own equity that would have previously been accounted for as derivatives and modifies the diluted earnings per share calculations for convertible instruments. We early adopted the new standard on January 1, 2021 on a modified retrospective basis. Refer to Note 7 – Long-Term Debt and Revolving Credit Arrangements for the impact of adoption on our 2025 Convertible Notes and Note 11 – Net Income (Loss) Per Share for the impact on our earnings per share calculation. Recently Issued Accounting Pronouncements Not Yet Adopted In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides optional expedients and exceptions to contract modifications and hedging relationships that reference LIBOR or another reference rate expected to be discontinued. The standard is effective upon issuance through December 31, 2022 and may be applied at the beginning of the interim period that includes March 12, 2020 or any date thereafter. We are currently evaluating the impact of this accounting standard update on our consolidated financial statements.

Revenue from Contract with Customer [Abstract]
Revenue	Note 2 – Revenue The following tables present our revenues disaggregated by offering and geographical region. Revenue by geographical region is based on where the transaction occurred. This level of disaggregation takes into consideration how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2020 2021 2020 2021 Mobility revenue $ 1,364 $ 2,205 $ 4,618 $ 4,676 Delivery revenue 1,136 2,238 2,548 5,942 Freight revenue 288 402 698 1,051 All Other revenue 25 — 110 8 Total revenue $ 2,813 $ 4,845 $ 7,974 $ 11,677 Three Months Ended September 30, Nine Months Ended September 30, 2020 2021 2020 2021 United States and Canada $ 1,598 $ 2,648 $ 4,798 $ 6,481 Latin America ("LatAm") 302 390 993 999 Europe, Middle East and Africa ("EMEA") 590 1,064 1,421 2,218 Asia Pacific ("APAC") 323 743 762 1,979 Total revenue $ 2,813 $ 4,845 $ 7,974 $ 11,677 Revenue Mobility Revenue We derive revenue primarily from fees paid by Mobility Drivers for the use of our platform(s) and related service to facilitate and complete Mobility transactions. In certain markets, we charge end-users a fee for connection services obtained via the platform. We recognized total revenue of $61 million and $253 million associated with these fees for the three and nine months ended September 30, 2020, respectively, and total revenue of $90 million and $216 million for the three and nine months ended September 30, 2021, respectively. Mobility revenue also includes immaterial revenue streams such as our Uber for Business (“U4B”) and financial partnership products. Delivery Revenue We derive revenue for Delivery from Merchants’ and Couriers’ use of the Delivery platform and related service to facilitate and complete Delivery transactions. Additionally, in certain markets where we are responsible for delivery services, delivery fees charged to end-users are also included in revenue, while payments to Couriers in exchange for delivery services are recognized in cost of revenue. In these markets, we recognized revenue from end-users of $28 million and $49 million for the three and nine months ended September 30, 2020, respectively, and revenue from end-users of $228 million and $490 million for the three and nine months ended September 30, 2021, respectively. We also recognized cost of revenue for these delivery transactions, exclusive of depreciation and amortization of $119 million and $269 million for the three and nine months ended September 30, 2020, respectively, and cost of revenue of $642 million and $1.5 billion for the three and nine months ended September 30, 2021, respectively. Subscription Offering We offer subscription memberships to end-users including Uber Pass, Rides Pass, and Eats Pass (“Subscription”). We recognize Subscription fees ratably over the life of the pass. We allocate Subscription fees earned to our segments on a proportional basis, based on usage for each segment during the respective period. Freight Revenue Freight revenue consists of revenue from freight transportation services provided to shippers. All Other Revenue All Other revenue primarily includes collaboration revenue related to our Advanced Technologies Group (“ATG”) business and revenue from our New Mobility offerings and products. ATG collaboration revenue was related to a three-year joint collaboration agreement we entered into in 2019. During the first quarter of 2021, we completed the sale of Apparate USA LLC (“Apparate” or the “ATG Business”) to Aurora Innovation, Inc. (“Aurora”). Refer to Note 17 – Divestiture for further information. New Mobility offerings and products provided users access to rides through a variety of modes, including dockless e-bikes and e-scooters (“New Mobility”), platform incubator group offerings and other immaterial revenue streams. After the JUMP divestiture during the second quarter of 2020, revenue from New Mobility products, including dockless e-bikes, was no longer material. Contract Balances and Remaining Performance Obligation Contract liabilities represents consideration collected prior to satisfying the performance obligations. As of September 30, 2021, we had $195 million of contract liabilities included in accrued and other current liabilities as well as other long-term liabilities on the condensed consolidated balance sheet. Revenue recognized from these contracts during the three and nine months ended September 30, 2020 and 2021 was not material. Our remaining performance obligation for contracts with an original expected length of greater than one year is expected to be recognized as follows (in millions): Less Than or Greater Than Total As of September 30, 2021 $ 46 $ 138 $ 184

Investments and Fair Value Measurement	Note 3 – Investments and Fair Value Measurement Investments Our investments on the condensed consolidated balance sheets consisted of the following (in millions): As of December 31, 2020 September 30, 2021 Classified as short-term investments: Marketable debt securities (1) : Commercial paper $ 457 $ — U.S. government and agency securities 429 — Corporate bonds 294 — Short-term investments $ 1,180 $ — Classified as investments: Non-marketable equity securities: Didi $ 6,299 $ 4,126 Aurora (2) — 2,250 Other (3) 329 307 Non-marketable debt securities: Grab (4) 2,341 4,089 Marketable equity securities — 1,386 Note receivable from a related party 83 81 Investments $ 9,052 $ 12,239 (1) Excluding marketable debt securities classified as cash equivalents and restricted cash equivalents. (2) For further information, see the section titled “Aurora Investments” below and Note 17 – Divestiture. (3) These balances include certain investments recorded at fair value with changes in fair value recorded in earnings due to the election of the fair value option of accounting for financial instruments. (4) Recorded at fair value with changes in fair value recorded in other comprehensive income (loss), net of tax, unless subject to credit loss. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents our financial assets and liabilities measured at fair value on a recurring basis based on the three-tier fair value hierarchy (in millions): As of December 31, 2020 As of September 30, 2021 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Financial Assets Money market funds $ 2,386 $ — $ — $ 2,386 $ 4,214 $ — $ — $ 4,214 Commercial paper — 611 — 611 — — — — U.S. government and agency securities — 542 — 542 — — — — Corporate bonds — 323 — 323 — — — — Non-marketable debt securities — — 2,341 2,341 — — 4,089 4,089 Non-marketable equity securities — — 52 52 — 4,126 2,278 6,404 Marketable equity securities — — — — 1,386 — — 1,386 Note receivable from a related party — — 83 83 — — 81 81 Total financial assets $ 2,386 $ 1,476 $ 2,476 $ 6,338 $ 5,600 $ 4,126 $ 6,448 $ 16,174 Financial Liabilities MLU B.V.

Didi Investment During the first quarter of 2021, we completed the sale of $500 million of our Didi shares and realized immaterial gains from this transaction. In addition, we recorded unrealized gains of $71 million from remeasurement of the carrying value of the remaining Didi shares under the measurement alternative during the three months ended March 31, 2021. On June 30, 2021, Didi started trading on the New York Stock Exchange, therefore our investment in preferred shares of Didi, which was previously accounted for under the measurement alternative on a non-recurring basis, had a readily determinable fair value and therefore changed to an investment measured at fair value on a recurring basis. As of September 30, 2021, our Didi investment in preferred shares has been converted to ordinary shares and classified as a non-marketable equity security due to a restriction on trading of ordinary shares. As of September 30, 2021, the fair value of our Didi investment is based on readily available pricing sources for comparable instruments, adjusted by a discount for lack of marketability due to the restriction on trading the shares (Level 2). During the three and nine months ended September 30, 2021,we recognized an unrealized loss of $3.2 billion and $1.7 billion, respectively, on this investment in other income (expense), net in our condensed consolidated statements of operations. Zomato Investment In July 2021, Zomato Media Private Limited (“Zomato”), in which we held preferred shares that were previously classified as non-marketable equity securities and accounted for under the measurement alternative on a non-recurring basis, completed its initial public offering (“IPO”) in India. As of September 30, 2021, our Zomato investment has been converted to ordinary shares and classified as a marketable equity security with a readily determinable fair value (Level 1) in the table presenting our financial assets and liabilities measured at fair value on a recurring basis. During the three and nine months ended September 30, 2021, we recognized an unrealized gain of $994 million on this investment in other income (expense), net in our condensed consolidated statements of operations. As of September 30, 2021, the carrying value of the investment was $1.1 billion. Our investment is subject to a lock-up period in which our ability to sell is restricted until July 2022. During the nine months ended September 30, 2021, we did not make any transfers between the levels of the fair value hierarchy. The following table summarizes the amortized cost and fair value of our debt securities with a stated contractual maturity or redemption date (in millions): As of September 30, 2021 Amortized Cost Fair Value Within one year $ — $ — One year through five years 2,281 4,089 Total $ 2,281 $ 4,089 The following table summarizes the amortized cost, unrealized gains and losses, and fair value of our debt securities at fair value on a recurring basis (in millions): As of December 31, 2020 As of September 30, 2021 Amortized Cost Unrealized Gains Unrealized Losses Fair Value Amortized Cost Unrealized Gains Unrealized Losses Fair Value Commercial paper $ 611 $ — $ — $ 611 $ — $ — $ — $ — U.S. government and agency securities 542 — — 542 — — — — Corporate bonds 322 1 — 323 — — — — Non-marketable debt securities 2,281 60 — 2,341 2,281 1,808 — 4,089 Total $ 3,756 $ 61 $ — $ 3,817 $ 2,281 $ 1,808 $ — $ 4,089 As of December 31, 2020 and September 30, 2021, there were no allowance for credit losses related to our available-for-sale debt securities. We measure our cash equivalents and certain investments at fair value. Level 1 instrument valuations are based on quoted market prices of the identical underlying security. Level 2 instrument valuations are obtained from readily available pricing sources for comparable instruments, identical instruments in less active markets, or models using market observable inputs. Level 3 instrument valuations are valued based on unobservable inputs and other estimation techniques due to the absence of quoted market prices, inherent lack of liquidity and the long-term nature of such financial instruments. As of December 31, 2020 and September 30, 2021, our Level 3 non-marketable debt securities and non-marketable equity securities primarily consist of common stock investments and preferred stock investments in privately held companies without readily determinable fair values. Depending on the investee’s financing activity in a reporting period, management’s estimate of fair value may be primarily derived from the investee’s financing transactions, such as the issuance of preferred stock to new investors. The price in these transactions generally provides the best indication of the enterprise value of the investee. Additionally, based on the timing, volume, and other characteristics of the transaction, we may supplement this information by using other valuation techniques, including the guideline public company approach. The guideline public company approach relies on publicly available market data of comparable companies and uses comparative valuation multiples of the investee’s revenue (actual and forecasted), and therefore, unobservable input used in this valuation technique primarily consists of short-term revenue projections. Once the fair value of the investee is estimated, an option-pricing model (“OPM”), a common stock equivalent (“CSE”) method or a hybrid approach is employed to allocate value to various classes of securities of the investee, including the class owned by us. The model involves making assumptions around the investees’ expected time to liquidity and volatility. An increase or decrease in any of the unobservable inputs in isolation, such as the security price in a significant financing transaction of the investee, could result in a material increase or decrease in our estimate of fair value. Other unobservable inputs, including short-term revenue projections, time to liquidity, and volatility are less sensitive to the valuation in the respective reporting periods, as a result of the primary weighting on the investee’s financing transactions. In the future, depending on the weight of evidence and valuation approaches used, these or other inputs may have a more significant impact on our estimate of fair value. We determine realized gains or losses on the sale of equity and debt securities on a specific identification method. Grab Investment To determine the fair value of our investment in Grab as of September 30, 2021, we utilized a hybrid approach, incorporating a CSE method along with an OPM. The CSE method assumes an if-converted scenario (for example an IPO or a special purpose acquisition company (“SPAC”) transaction), where the OPM approach allocates equity value to individual securities within the investees’ capital structure based on contractual rights and preferences. As a result of the valuation performed, we recognized pre-tax unrealized gains of $497 million and $1.7 billion on this investment during the three and nine months ended September 30, 2021, respectively, in other comprehensive income (loss), net of tax in our condensed consolidated statements of comprehensive income (loss). The following table summarizes information about the significant unobservable inputs used in the fair value measurement for our Grab investment as of September 30, 2021: Fair value method Relative weighting Key unobservable inputs OPM 40% Transaction price per share $6.16 Volatility 64% Estimated time to liquidity 1.25 years Market adjustment 5% CSE 60% Discount rate 25% Estimated time to liquidity 0.25 years Aurora Investments On January 19, 2021, we completed the sale of our ATG Business to Aurora. As consideration for the sale of our ATG Business to Aurora, we received common stock in Aurora. Concurrently, we invested in Aurora’s preferred stock. For further information, refer to Note 17 – Divestiture. We hold one seat on Aurora’s board of directors and have the ability to hold a second seat, which, along with our common and preferred stock ownership (our “Aurora Investments”) generate significant influence. We elected to apply the fair value option to our Aurora common stock and preferred stock investments in order to provide consistency of accounting treatment to our Aurora Investments. The Aurora Investments are measured at fair value on a recurring basis with changes in fair value reflected in other income (expense), net, in the condensed consolidated statements of operations. The fair value of the Aurora Investments as of September 30, 2021 was determined by a hybrid approach, incorporating a CSE method along with an OPM, weighted at 50% and 50%, respectively, as a result of an announced SPAC merger. The CSE method assumes an if-converted scenario (for example a SPAC), where the OPM approach allocates equity value to individual securities within the investees’ capital structure based on contractual rights and preferences. Significant unobservable inputs to the OPM were volatility of 66% and time to liquidity of 4.25 years. As a result of the valuation performed, we recognized unrealized gains of $102 million and $573 million on this investment in other income (expense), net in our condensed consolidated statements of operations during the three and nine months ended September 30, 2021, respectively. Summarized financial information for Aurora for the six months ended June 30, 2021, the most recent period available, is as follows (in millions): Results of Operations Data Six Months Ended June 30, 2021 Total operating expenses $ 373 Loss from operations (373) Net loss (370) Balance Sheet Data As of June 30, 2021 Current assets $ 808 Total assets 2,796 Current liabilities 72 Total liabilities 254 Redeemable convertible preferred stock 2,161 Financial Assets and Liabilities Measured at Fair Value Using Level 3 Inputs The following table presents a reconciliation of our financial assets and liabilities measured and recorded at fair value on a recurring basis as of September 30, 2021, using significant unobservable inputs (Level 3) (in millions): Non-marketable Non-marketable Equity Securities Note Receivables MLU B.V.

Such fair value measurements are based predominantly on Level 3 inputs. Non-Marketable Equity Securities Our non-marketable equity securities are investments in privately held companies without readily determinable fair values. The carrying value of our non-marketable equity securities are adjusted based on price changes from observable transactions of identical or similar securities of the same issuer (referred to as the measurement alternative) or for impairment. Any changes in carrying value are recorded within other income (expense), net in the condensed consolidated statements of operations. Non-marketable equity securities are classified within Level 3 in the fair value hierarchy because we estimate the fair value of these securities based on valuation methods, including the CSE and OPM methods, using the transaction price of similar securities issued by the investee adjusted for contractual rights and obligations of the securities we hold. We did not record any realized gains or losses for our non-marketable equity securities measured at fair value on a non-recurring basis during the three and nine months ended September 30, 2020 and 2021. The following is a summary of unrealized gains and losses from remeasurement (referred to as upward or downward adjustments) recorded in other income (expense), net in the condensed consolidated statements of operations, and included as adjustments to the carrying value of non-marketable equity securities (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2020 2021 2020 2021 Upward adjustments $ — $ — $ — $ 71 Downward adjustments (including impairment) — — (1,690) — Total unrealized gain (loss) for non-marketable equity securities $ — $ — $ (1,690) $ 71 The following table summarizes the total carrying value of our non-marketable equity securities measured at fair value on a non-recurring basis held, including cumulative unrealized upward and downward adjustments made to the initial cost basis of the securities (in millions): As of December 31, 2020 September 30, 2021 Initial cost basis $ 6,282 $ 279 Upward adjustments 1,984 — Downward adjustments (including impairment) (1,690) — Total carrying value at the end of the period $ 6,576 $ 279

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments	Note 4 – Equity Method Investments The carrying value of our equity method investments were as follows (in millions): As of December 31, 2020 September 30, 2021 MLU B.V. $ 1,001 $ 927 Mission Bay 3 & 4 41 38 Other 37 6 Total equity method investments $ 1,079 $ 971 MLU B.V. and Uber Russia/CIS Operations On August 30, 2021, we entered into an agreement (the “Framework Agreement”) with Yandex N.V. (“Yandex”) to restructure our joint ventures, MLU B.V. and Yandex Self Driving Group B.V. (“SDG”). Pursuant to the Framework Agreement, we completed the sale of our entire equity interest in SDG and 4.5% of equity interest in MLU B.V. to Yandex during the third quarter of 2021 (collectively, the “Initial Closing”). In addition, Yandex is expected to spin-off by way of demerger from MLU B.V. the Yandex.Eats, Yandex.Lavka and Yandex.Delivery businesses (“Demerger”). Immediately following the Demerger, Yandex will acquire all of our equity interest in such demerged businesses (“Demerger Share Closing”). If the Demerger Share Closing does not occur by December 31, 2021 (with a certain 30-day extension), we will instead transfer an additional 6.7% stake of our MLU B.V. ownership to Yandex. The total consideration payable by Yandex to us in respect of the Framework Agreement is approximately $1.0 billion in cash, of which (i) $800 million was paid during the third quarter of 2021, and (ii) $200 million will be paid at the Demerger Share Closing, which is expected to occur in the fourth quarter of 2021. At the Initial Closing during the third quarter of 2021, we allocated consideration of $276 million to the sale of 4.5% of equity interest in MLU B.V. and we recognized a gain of $106 million in other income (expense), net on our condensed consolidated statement of operations during the three months ended September 30, 2021. As of September 30, 2021, our equity ownership interest in MLU B.V. was reduced to 29%. The consideration allocated and gains recognized for the sale of our entire equity interest in SDG were not material. In addition, we recognized a liability of $212 million in accrued and other current liabilities on our condensed consolidated balance sheet as of September 30, 2021 for the consideration allocated to a prepayment received for the Demerger Share Closing. In connection with the Framework Agreement, we granted Yandex an option (“MLU B.V. Call Option”) to acquire our remaining equity interest in MLU B.V. during the two-year period following the Initial Closing. The initial exercise price of the MLU B.V. Call Option is approximately $2.0 billion, subject to certain adjustments based on the successful closing of the Demerger Share Closing and the timing of the option exercise. As of September 30, 2021, we allocated consideration of $230 million to the MLU B.V. Call Option, which is recorded as a liability in accrued and other current liabilities on our condensed consolidated balance sheet. The MLU B.V. Call Option is measured at fair value on a recurring basis with changes in fair value recorded in other income (expense), net in the condensed consolidated statements of operations. To determine the fair value of the MLU B.V. Call Option as of September 30, 2021, we used a lattice model which simulated multiple scenarios of the exercise behaviors and the corresponding strike prices over the term of the call option. Key inputs to the lattice model were underlying business value, option term, volatility, risk-free interest rates, and dividend yield (Level 3). Included in the carrying value of MLU B.V. is the basis difference, net of amortization, between the original cost of the investment and our proportionate share of the net assets of MLU B.V. The carrying value of the equity method investment is primarily adjusted for our share in the income or losses of MLU B.V. on a one-quarter lag basis and amortization of basis differences. Equity method goodwill and intangible assets, net of accumulated amortization are also adjusted for currency translation adjustments representing fluctuations between the functional currency of the investee, the Ruble and the U.S. Dollar. The table below provides the composition of the basis difference (in millions): As of September 30, 2021 Equity method goodwill $ 698 Intangible assets, net of accumulated amortization 60 Deferred tax liabilities (13) Cumulative currency translation adjustments (130) Basis difference $ 615 We amortize the basis difference related to the intangible assets over the estimated useful lives of the assets that gave rise to the difference using the straight-line method. The weighted-average life of the intangible assets is ap proximately 3.4 years as of September 30, 2021. Equity method goodwill is not amortized. The investment balance is reviewed for impairment whenever factors indicate that the carrying value of the equity method investment may not be recoverable. As of September 30, 2021, we determined that there was no impairment of our investment of MLU B.V.

The $2.6 billion is comprised of (i) a $1.1 billion tranche with a maturity date of February 25, 2027, replacing the 2016 Senior Secured Term Loan as a Refinancing Term Loan (the “2027 Refinanced Term Loan”), and (ii) a $1.5 billion tranche with a maturity date of April 4, 2025, replacing the 2018 Senior Secured Term Loan as an Incremental Term Loan (the “2025 Refinanced Term Loan”). The refinancing transaction qualified as a debt modification that did not result in an extinguishment. The 2025 Refinanced Term Loan and the 2027 Refinanced Term Loan are guaranteed by certain of our material domestic restricted subsidiaries. The 2025 Refinanced Term Loan and the 2027 Refinanced Term Loan agreements contain customary covenants restricting our and certain of our subsidiaries’ ability to incur debt, incur liens and undergo certain fundamental changes. We were in compliance with all covenants as of September 30, 2021. The loan is secured by certain of our intellectual property and equity of certain material foreign subsidiaries. The fair values of our 2025 Refinanced Term Loan and 2027 Refinanced Term Loan were $1.5 billion and $1.1 billion, respectively, as of September 30, 2021 and were determined based on quoted prices in markets that are not active, which is considered a Level 2 valuation input. 2025 Convertible Note In December 2020, we issued $1.15 billion aggregate principal amount of 0% convertible senior notes due in 2025 (the “2025 Convertible Notes”), including the exercise in full by the initial purchasers of the 2025 Convertible Notes of their option to purchase up to an additional $150 million principal amount of the 2025 Convertible Notes. The 2025 Convertible Notes were issued in a private placement to qualified institutional buyers pursuant to Rule144A under the Securities Act. The 2025 Convertible Notes will mature on December 15, 2025, unless earlier converted, redeemed or repurchased. Holders of the 2025 Convertible Notes may convert their notes at their option at any time prior to the close of business on the business day immediately preceding September 15, 2025 only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on March 31, 2021 (and only during such calendar quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (ii) during the five business day period after any ten consecutive trading day period (the “measurement period”) in which the trading price (as defined below) per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; (iii) if we call such notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the applicable redemption date; or (iv) upon the occurrence of specified corporate events. On or after September 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their notes at any time, regardless of the foregoing circumstances. As of September 30, 2021, none of the conditions permitting the holders of the 2025 Convertible Notes to convert their notes early had been met. Therefore, the 2025 Convertible Notes are classified as long-term. The initial conversion rate is 12.3701 shares of common stock per $1,000 principal amount of notes, equivalent to an initial conversion price of approximately $80.84 per share of common stock. The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid special interest. Upon conversion of the 2025 Convertible Notes, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. We may not redeem the notes prior to December 20, 2023. We may redeem for cash all or any portion of the notes, at our option, on or after December 20, 2023 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date. The indenture governing the 2025 Convertible Notes does not contain any financial or operating covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by us or any of our subsidiaries. Prior to the adoption of ASU 2020-06, the proceeds from the issuance of the 2025 Convertible Notes were allocated between the conversion feature recorded as equity and the liability for the notes themselves. The difference of $243 million between the principal amount of the 2025 Convertible Notes and the liability component (the “debt discount”) was amortized to interest expense using the effective interest method over the term of the 2025 Convertible Notes. The equity component of the 2025 Convertible Notes was included in additional paid-in capital in the consolidated balance sheet as of December 31, 2020 and was not remeasured as it continued to meet the conditions for equity classification. To determine the fair value of the liability component of the 2025 Convertible Notes as of the pricing date, we used the binomial model with inputs of time to maturity, conversion ratio, our stock price, risk free rate and volatility. Effective January 1, 2021, we early adopted ASU 2020-06 using the modified retrospective approach. The adoption of this standard resulted in a decrease to additional paid-in capital of $243 million and an increase to our 2025 Convertible Notes by the same amount. At adoption, there was no adjustment recorded to the opening accumulated deficit as the cumulative effect was immaterial. Interest expense recognized in future periods will be reduced as a result of accounting for the 2025 Convertible Notes as a single liability measured at its amortized cost. The fair value of our 2025 Convertible Notes was $1.1 billion as of September 30, 2021 and was determined based on quoted prices in markets that are not active, which is considered a Level 2 valuation input. Senior Notes In August 2021, we issued eight-year notes with an aggregate principal amount of $1.5 billion due on August 15, 2029 (the “2029 Senior Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. We issued the 2029 Senior Notes at par and paid approximately $16 million for debt issuance costs. The interest is payable semi-annually in arrears on February 15 and August 15 of each year at 4.50% per annum, beginning on February 15, 2022, and the entire principal amount is due at the time of maturity. We intend to use the net proceeds from this offering to finance a portion of the consideration payable in cash, and certain related fees and expenses incurred, in connection with the pending acquisition of Tupelo Parent, Inc. (“Transplace”), by our majority-owned subsidiary, Uber Freight Holding Corporation (“Freight Holding”). The Transplace acquisition is subject to regulatory approval and other customary closing conditions and is expected to close in late 2021. The 2029 Senior Notes are subject to a special mandatory redemption, which provides that if the acquisition of Transplace is not consummated on or before February 28, 2023, or if, prior to such date, the definitive agreement (the “Stock Purchase Agreement”) entered into between us and Freight Holding to acquire Transplace is terminated, we will be required to redeem all of the outstanding 2029 Senior Notes equal to 100% of the aggregate principal amount of such notes, plus accrued and unpaid interest on the principal amount of such notes. As of September 30, 2021, none of the conditions permitting the holders of the 2029 Senior Notes to redeem had been met. Therefore, the 2029 Senior Notes are classified as long-term. The 2025, 2026, 2027, 2028 and 2029 Senior Notes (collectively “Senior Notes”) are guaranteed by certain of our material domestic restricted subsidiaries. The indentures governing the Senior Notes contain customary covenants restricting our and certain of our subsidiaries’ ability to incur debt and incur liens, as well as certain financial covenants specified in the indentures. We were in compliance with all covenants as of September 30, 2021. The following table presents the fair values of our Senior Notes as of September 30, 2021, and were determined based on quoted prices in markets that are not active, which is considered a Level 2 valuation input (in millions): As of September 30, 2021 2025 Senior Note $ 1,067 2026 Senior Note 1,598 2027 Senior Note 1,323 2028 Senior Note 538 2029 Senior Note 1,511 Total $ 6,037 The following table presents the amount of interest expense recognized relating to the contractual interest coupon and amortization of the debt discount and issuance costs with respect to our long term debt, for the three and nine months ended September 30, 2020 and 2021 (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2020 2021 2020 2021 Contractual interest coupon $ 118 $ 118 $ 333 $ 338 Amortization of debt discount and issuance costs 3 3 8 13 Total interest expense from long-term debt $ 121 $ 121 $ 341 $ 351 Revolving Credit Arrangements We have a revolving credit agreement initially entered in 2015 with certain lenders, which provides for $2.3 billion in credit maturing on June 13, 2023 (“Revolving Credit Facility”). The Revolving Credit Facility may be guaranteed by certain of our material domestic restricted subsidiaries based on certain conditions. The credit agreement contains customary covenants restricting our and certain of our subsidiaries’ ability to incur debt, incur liens, and undergo certain fundamental changes, as well as maintain a certain level of liquidity specified in the contractual agreement. The credit agreement also contains customary events of default. The Revolving Credit Facility also contains restrictions on the payment of dividends. As of September 30, 2021, there was no balance outstanding on the Revolving Credit Facility. Letters of Credit As of December 31, 2020 and September 30, 2021, we had letters of credit outstanding of $649 million and $763 million, respectively, of which the letters of credit that reduced the available credit under the Revolving Credit Facility were $233 million and $263 million, respectively.

Stockholders' Equity	Note 9 – Stockholders' Equity Equity Compensation Plans We maintain four equity compensation plans that provide for the issuance of shares of our common stock to our officers and other employees, directors, and consultants: the 2010 Stock Plan (the “2010 Plan”), the 2013 Equity Incentive Plan (the “2013 Plan”), the 2019 Equity Incentive Plan (the “2019 Plan”), and the 2019 Employee Stock Purchase Plan (the “ESPP”), which have all been approved by stockholders. Following our IPO in 2019, we have only issued awards under the 2019 Plan and the ESPP, and no additional awards will be granted under the 2010 and 2013 Plans. These plans provide for the issuance of incentive stock options (“ISOs”), nonqualified stock options (“NSOs”), stock appreciation rights (“SARs”), restricted stock awards, restricted stock units (“RSUs”), performance-based awards, and other awards (that are based in whole or in part by reference to our common stock).

Income Taxes	Note 10 – Income Taxes We compute our quarterly income tax expense/(benefit) by using a forecasted annual effective tax rate and adjust for any discrete items arising during the quarter. We recorded an income tax expense/(benefit) of $23 million and $(215) million for the three and nine months ended September 30, 2020, respectively, and $(101) million and $(395) million for the three and nine months ended September 30, 2021, respectively. During the three months ended September 30, 2020, the income tax expense was primarily driven by current tax on foreign earnings offset by a partial benefit from U.S. losses. During the nine months ended September 30, 2020, the income tax benefit was primarily driven by the deferred U.S. tax impact of the impairment charges related to our investments in Didi, the deferred China tax impact of the impairment charge related to our investment in Didi, and to a lesser extent, the benefit of U.S. losses and current tax on foreign earnings. During the three months ended September 30, 2021, the income tax benefit was primarily driven by the deferred U.S. tax impact related to our investments in Didi and Zomato, and to a lesser extent, by the benefit of U.S. losses and current tax on our foreign earnings. During the nine months ended September 30, 2021, the income tax benefit was primarily driven by the deferred China and U.S. tax impact related to our investment in Didi, the deferred U.S. tax impact related to our investments in Aurora and Zomato, and to a lesser extent, the benefit from our U.S. losses and current tax on our foreign earnings. The primary differences between the effective tax rate and the federal statutory tax rate are due to the China and U.S. deferred taxes related to our investment in Didi, U.S. deferred taxes related to our investments in Aurora and Zomato, the valuation allowance on our U.S. and Netherlands' deferred tax assets, and foreign tax rate differences. During the nine months ended September 30, 2021, the amount of gross unrecognized tax benefits increased by $206 million, of which approximately $50 million of unrecognized tax benefits, if recognized, would impact the effective tax rate. The remaining $156 million of unrecognized tax benefits would not impact the effective tax rate due to the valuation allowance against certain deferred tax assets. We are subject to taxation in the U.S. and various state and foreign jurisdictions. We are also under routine examination by federal, various state and foreign tax authorities. We believe that adequate amounts have been reserved in these jurisdictions. To the extent we have tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon examination by the federal, state or foreign tax authorities to the extent utilized in a future period. For our major tax jurisdictions, the tax years 2002 through 2021 remain open; the major tax jurisdictions are the U.S., Brazil, Netherlands, and Australia. Although the timing of the resolution and/or closure of audits is highly uncertain, we do not expect any material changes to our unrecognized tax benefits within the next 12 months. Given the number of years remaining subject to examination and the number of matters being examined, we are unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits. In the event we experience an ownership change within the meaning of Section 382 of the Internal Revenue Code (“IRC”), our ability to utilize net operating losses, tax credits and other tax attributes may be limited. The most recent analysis of our historical ownership changes was completed through September 30, 2021. Based on the analysis, we do not anticipate a current limitation on the tax attributes.

Net Income (Loss) Per Share

Earnings Per Share [Abstract]
Net Income (Loss) Per Share	Note 11 – Net Income (Loss) Per Share Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding for the periods presented. Diluted net income (loss) per share is computed by giving effect to all potential weighted average dilutive common stock. The dilutive effect of outstanding awards and convertible securities is reflected in diluted net income (loss) per share by application of the treasury stock method. Since we were in a loss position for each of the periods presented, basic net loss per share was the same as diluted net loss per share for the periods presented. We take into account the effect on consolidated net income (loss) per share of dilutive securities of entities in which we hold equity interests that are accounted for using the equity method. The following table sets forth the computation of basic and diluted net income (loss) per share attributable to common stockholders (in millions, except share amounts which are reflected in thousands, and per share amounts): Three Months Ended September 30, Nine Months Ended September 30, 2020 2021 2020 2021 Basic net income (loss) per share: Numerator Net loss including non-controlling interests $ (1,108) $ (2,439) $ (5,826) $ (1,449) Add: net loss attributable to non-controlling interests, net of tax (19) (15) (27) (61) Net loss attributable to common stockholders $ (1,089) $ (2,424) $ (5,799) $ (1,388) Denominator Basic weighted-average common stock outstanding 1,755,029 1,898,954 1,739,488 1,877,655 Basic net loss per share attributable to common stockholders (1) $ (0.62) $ (1.28) $ (3.33) $ (0.74) Diluted net income (loss) per share: Numerator Net income (loss) attributable to common stockholders $ (1,089) $ (2,424) $ (5,799) $ (1,388) Net loss attributable to Freight Holding convertible common shares non-controlling interest, net of tax — — — (27) Diluted net loss attributable to common stockholders $ (1,089) $ (2,424) $ (5,799) $ (1,415) Denominator Number of shares used in basic net income (loss) per share computation 1,755,029 1,898,954 1,739,488 1,877,655 Weighted-average effect of potentially dilutive securities: Assumed redemption of Freight Holding common shares, non-controlling interest — — — 1,342 Diluted weighted-average common stock outstanding 1,755,029 1,898,954 1,739,488 1,878,997 Diluted net loss per share attributable to common stockholders (1) $ (0.62) $ (1.28) $ (3.33) $ (0.75) (1) Per share amounts are calculated using unrounded numbers and therefore may not recalculate. Effective January 1, 2021, we early adopted ASU 2020-06 using the modified retrospective approach. Upon adoption, we use the if-converted method and presume share settlement for our 2025 Convertible Notes and our non-interest bearing unsecured convertible notes related to the acquisition of Careem (“Careem Notes”) when calculating the dilutive effect of these notes. The following potentially dilutive outstanding securities were excluded from the computation of diluted net income (loss) per share because their effect would have been anti-dilutive for the periods presented, or issuance of such shares is contingent upon the satisfaction of certain conditions which were not satisfied by the end of the period (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2020 2021 2020 2021 Freight Holding contingently redeemable preferred stock — 9,077 — 9,077 RSUs 93,508 75,161 93,508 75,161 Stock options 25,492 24,694 25,492 24,694 Common stock subject to repurchase 28 4,540 28 4,540 RSUs to settle fixed monetary awards 109 — 109 — Shares committed under ESPP 2,016 2,758 2,016 2,758 Warrants to purchase common stock 126 73 126 73 Convertible notes 14,181 20,655 14,181 22,604 Total 135,460 136,958 135,460 138,907

Segment Information and Geograp

Segment Reporting [Abstract]
Segment Information and Geographic Information	Note 12 – Segment Information and Geographic Information We determine our operating segments based on how the chief operating decision maker (“CODM”) manages the business, allocates resources, makes operating decisions and evaluates operating performance. As of the first quarter of 2021, our three operating and reportable segments are as follows: Segment Description Mobility Mobility products connect consumers with Drivers who provide rides in a variety of vehicles, such as cars, auto rickshaws, motorbikes, minibuses, or taxis. Mobility also includes activity related to our U4B, Financial Partnerships, Transit and Vehicle Solutions offerings. Delivery Delivery offerings allow consumers to search for and discover local restaurants, order a meal, and either pick-up at the restaurant or have the meal delivered. In certain markets, Delivery also includes offerings for grocery and convenience store delivery as well as select other goods. Freight Freight connects carriers with shippers on our platform, and gives carriers upfront, transparent pricing and the ability to book a shipment. In January 2021, we sold our ATG Business to Aurora. Our ATG Business was included in the ATG and Other Technology Programs segment prior to this transaction. As a result of the sale, ATG and Other Technology Programs segment was no longer a reportable segment. Beginning in the first quarter of 2021, results of ATG and Other Technology Programs are included within All Other. Refer to Note 17 – Divestiture for further information regarding the sale of our ATG Business. For information about how our reportable segments derive revenue, refer to Note 2 – Revenue. Our segment operating performance measure is segment adjusted EBITDA. The CODM does not evaluate operating segments using asset information and, accordingly, we do not report asset information by segment. Segment adjusted EBITDA is defined as revenue less the following expenses: cost of revenue, operations and support, sales and marketing, and general and administrative and research and development expenses associated with our segments. Segment adjusted EBITDA also excludes non-cash items or items that management does not believe are reflective of our ongoing core operations (as shown in the table below). The following table provides information about our segments and a reconciliation of the total segment adjusted EBITDA to loss from operations (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2020 2021 2020 2021 Segment adjusted EBITDA: Mobility $ 245 $ 544 $ 876 $ 1,021 Delivery (183) (12) (728) (373) Freight (73) (35) (186) (105) All Other (1) (104) — (389) (11) Total segment adjusted EBITDA (115) 497 (427) 532 Reconciling items: Corporate G&A and Platform R&D (2), (3) (510) (489) (1,647) (1,392) Depreciation and amortization (138) (218) (395) (656) Stock-based compensation expense (183) (281) (591) (834) Legal, tax, and regulatory reserve changes and settlements — 98 (57) (593) Goodwill and asset impairments/loss on sale of assets (4) (76) — (285) (57) Acquisition, financing and divestitures related expenses (14) (23) (43) (85) Accelerated lease costs related to cease-use of ROU assets (4) (80) — (80) (2) COVID-19 response initiatives (18) (10) (90) (51) Gain on lease arrangement, net 12 — 5 — Restructuring and related charges, net 6 — (376) — Legacy auto insurance transfer (5) — (103) — (103) Mass arbitration fees for supporting Black-owned restaurants — (43) — (43) Loss from operations $ (1,116) $ (572) $ (3,986) $ (3,284) (1) Includes historical results of ATG and Other Technology Programs and New Mobility. (2) Excluding stock-based compensation expense. (3) Includes costs that are not directly attributable to our reportable segments. Corporate G&A also includes certain shared costs such as finance, accounting, tax, human resources, information technology and legal costs. Platform R&D also includes mapping and payment technologies and support and development of the internal technology infrastructure. Our allocation methodology is periodically evaluated and may change. (4) During the three months ended September 30, 2020, we exited, and made available for sublease, certain leased offices, primarily due to the City of San Francisco's extended shelter-in-place orders. This decision resulted in the recognition of accelerated lease expense and other asset impairments. (5) Refer to Note 1 – Description of Business and Summary of Significant Accounting Policies for further information. Geographic Information Revenue by geography is based on where the trip or shipment was completed or meal or grocery order delivered. The following table sets forth revenue by geographic area for the three and nine months ended September 30, 2020 and 2021 (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2020 2021 2020 2021 United States $ 1,455 $ 2,343 $ 4,442 $ 5,839 France 202 355 492 1,155 Australia 191 417 473 1,096 All other countries 965 1,730 2,567 3,587 Total revenue $ 2,813 $ 4,845 $ 7,974 $ 11,677 Revenue grouped by offerings and geographical region is included in Note 2 – Revenue.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 13 – Commitments and Contingencies Purchase Commitments We have commitments for network and cloud services, background checks, and other items in the ordinary course of business with varying expiration terms through October 30, 2024. These amounts are determined based on the non-cancelable quantities or termination amounts to which we are contractually obligated. As of September 30, 2021, there were no material changes to our purchase commitments disclosed in the financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2020. Contingencies From time to time, we are a party to various claims, non-income tax audits and litigation in the normal course of business. As of December 31, 2020 and September 30, 2021, we had recorded aggregate liabilities of $1.8 billion and $2.3 billion, respectively, of which $1.3 billion and $1.3 billion relate to non-income tax matters, respectively, in accrued and other current liabilities on the condensed consolidated balance sheets for all of our legal, regulatory and non-income tax matters that were probable and reasonably estimable. We are currently party to various legal and regulatory matters that have arisen in the normal course of business and include, among others, alleged independent contractor misclassification claims, Fair Credit Reporting Act (“FCRA”) claims, alleged background check violations, pricing and advertising claims, unfair competition claims, intellectual property claims, employment discrimination and other employment-related claims, Telephone Consumer Protection Act (“TCPA”) claims, Americans with Disabilities Act (“ADA”) claims, data and privacy claims, securities claims, antitrust claims, challenges to regulations, and other matters. We have existing litigation, including class actions, Private Attorney General Act lawsuits, arbitration claims, and governmental administrative and audit proceedings, asserting claims by or on behalf of Drivers that Drivers are misclassified as independent contractors. In connection with the enactment of California State Assembly Bill 5 (“AB5”), we have received and expect to continue to receive - in California and in other jurisdictions - an increased number of misclassification claims. With respect to our outstanding legal and regulatory matters, based on our current knowledge, we believe that the ultimate amount or range of reasonably possible loss will not, either individually or in the aggregate, have a material adverse effect on our business, financial position, results of operations, or cash flows. The outcome of such legal matters is inherently unpredictable and subject to significant uncertainties. If one or more of these matters were resolved against us for amounts in excess of management's expectations, our results of operations, financial condition or cash flows could be materially adversely affected. Driver Classification California Attorney General Lawsuit In January 2020, AB5 went into effect. AB5 codifies a test to determine whether a worker is an employee under California law. The test is referred to as the “ABC” test, and was originally handed down by the California Supreme Court in Dynamex Operations v. Superior Court in 2018. Under the ABC test, workers performing services for a hiring entity are considered employees unless the hiring entity can demonstrate three things: the worker (A) is free from the hiring entity’s control, (B) performs work that is outside the usual course of the hiring entity’s business, and (C) customarily engages in the independent trade, work or type of business performed for the hiring entity. On May 5, 2020, the California Attorney General, in conjunction with the city attorneys for San Francisco, Los Angeles and San Diego, filed a complaint in San Francisco Superior Court against Uber and Lyft, Inc. (“Lyft”). The complaint alleges drivers are misclassified, and seeks an injunction and monetary damages related to the alleged competitive advantage caused by the alleged misclassification of drivers. On August 10, 2020, the Court issued a preliminary injunction order, prohibiting us from classifying drivers as independent contractors and from violating various wage and hour laws. The injunction was stayed pending appeal. On October 22, 2020, the Court of Appeal affirmed the lower court’s ruling, and we filed a petition for review of the decision with the California Supreme Court. The petition was based upon the passage of Proposition 22 by California voters in November 2020, and requested that the Court of Appeal opinion be vacated because AB5’s application to Uber was superseded by Proposition 22. Proposition 22 was a state ballot initiative that provides a framework for drivers that use platforms like ours to qualify as independent workers. As a result of the passage of Proposition 22, Drivers are able to maintain their status as independent contractors under California law, and we and our competitors are required to comply with the provisions of Proposition 22. Proposition 22 went into effect on December 16, 2020. The California Supreme Court declined the petition for review on February 10, 2021. The lawsuit was returned to the trial court following the appellate proceedings on February 22, 2021. On April 12, 2021, the California Attorney General, Uber and Lyft filed a stipulation to dissolve the preliminary injunction with the trial court. On April 16, 2021, the trial court signed an order granting the stipulation. Although the preliminary injunction has been dissolved, the lawsuit remains ongoing relating to claims by the California Attorney General for periods prior to enactment of Proposition 22. We have petitioned to stay this matter pending coordination with other California employment related matters, which was granted and a coordination judge was assigned. We intend to continue to vigorously defend ourselves. Our chances of success on the merits are still uncertain and any reasonably possible loss or range of loss cannot be estimated. In addition, in January 2021, a petition was filed with the California Supreme Court by several drivers and a labor union alleging that Proposition 22 is unconstitutional, which was denied. The same drivers and labor union have since filed a similar challenge in California Superior Court, and in August 2021, the Alameda County Superior Court ruled that Proposition 22 is unconstitutional. On September 21, 2021, the State of California filed an appeal of that decision with the California Court of Appeal, and the Protect App-Based Drivers and Services has also filed an appeal. Massachusetts Attorney General Lawsuit On July 9, 2020, the Massachusetts Attorney General filed a complaint in Suffolk County Superior Court against Uber and Lyft. The complaint alleges Drivers are employees, and are entitled to protections under the wage and labor laws. The complaint was served on July 20, 2020 and Uber filed a motion to dismiss the complaint on September 24, 2020, which was denied on March 25, 2021. A summary judgment motion was filed in September 2021 and we filed a motion in which we argue that the motion is premature and should await the close of discovery. The motion is pending. Our chances of success on the merits are still uncertain and any reasonably possible loss or range of loss cannot be estimated. Postmates Arbitrations We have received demands or have been threatened with demands for individual arbitration on behalf of Couriers who claim to be misclassified as independent contractors by Postmates. These claims expose us to wage and hour and related liabilities for each individual who has filed a demand. The ultimate resolution of the arbitrations is uncertain and the amount accrued for this matter is recorded within accrued and other current liabilities on the condensed consolidated balance sheets, with a corresponding increase to goodwill, based on facts and circumstances in existence as of the effective date of the acquisition. Swiss Social Security Reclassification Several Swiss administrative bodies have issued decisions in which they classify Drivers as employees of Uber Switzerland, Rasier Operations B.V. or of Uber B.V. for social security or regulatory purposes. We are challenging each of them before the Social Security and Administrative Tribunals. In April 2020, a ruling was made on a separate matter in Switzerland which reclassified a Driver as an employee. In April 2021, a ruling was made that Uber Switzerland could not be held liable for social security contributions. The ultimate resolution of the social security matters for the other two entities is uncertain and the amount accrued for this matter is recorded within accrued and other current liabilities on the condensed consolidated balance sheets. Aslam, Farrar, Hoy and Mithu v. Uber B.V., Uber Britannia Ltd. and Uber London Ltd. On October 28, 2015, a claim by 25 Drivers, including Mr. Y. Aslam and Mr. J. Farrar, was brought in the UK Employment Tribunal against us asserting that they should be classified as “workers” (a separate category between independent contractors and employees) in the UK rather than independent contractors. The tribunal ruled on October 28, 2016 that Drivers were workers whenever our app is switched on and they are ready and able to take trips based on an assessment of the app in July 2016. The Court of Appeal rejected our appeal in a majority decision on December 19, 2018. We appealed to the Supreme Court and a hearing at the Supreme Court took place in July 2020. On February 19, 2021, the Supreme Court of the UK upheld the tribunal ruling that the Drivers using the app in 2016 were workers for UK employment law purposes. Damages include back pay including holiday pay and minimum wage, which will be assessed and quantified at a future hearing in July 2022. Additional claimants have also filed and each claimant will be required to bring their own separate action to an employment tribunal to determine whether they met the “worker” classification and if so, how much each claimant will be awarded. On March 16, 2021, we announced that more than 70,000 drivers in the UK will be treated as workers, earning at least the National Living Wage when driving with Uber. They will also be paid for holiday time and all those eligible will be automatically enrolled into a pension plan. We have also initiated a settlement process with drivers in the UK to proactively resolve historical claims relating to their classification under UK law. In addition, we expect to be subject to historical pension contributions, which requires our separate engagement with the UK pension regulator. On June 23, 2021, we received a compliance notice from the UK pension regulator to facilitate our auto-enrollment implementation. The pension regulator has confirmed that Uber will be required to pay historic company contributions, but that we are not required to pay the driver component of historic pension contributions unless we fail to comply in which case the amount equivalent to those contributions would be payable as a penalty. We have started enrolling eligible drivers into a pension plan. Our portal for drivers to register for a settlement of historical holiday pay and national minimum wage liabilities closed on July 22, 2021 and we have extended offers to all drivers eligible for settlement who are not already represented by an attorney and have made payments to the drivers who accepted our offers. We are currently in mediation with the drivers who are represented by one of three law firms who represent large cohorts of drivers. Compensation hearings will take place in 2022 for claimants who have not settled their historic claims, where the tribunal will assess our position on the correct approach to working time. While the ultimate resolution of these matters is uncertain, we have recorded an accrual for these matters within accrued and other current liabilities on the condensed consolidated balance sheet as of September 30, 2021. Other Driver Classification Matters Additionally, we have received other lawsuits and governmental inquiries in other jurisdictions, and anticipate future claims, lawsuits, arbitration proceedings, administrative actions, and government investigations and audits challenging our classification of Drivers as independent contractors and not employees. We believe that our current and historical approach to classification is supported by the law and intend to continue to defend ourselves vigorously in these matters. However, the results of litigation and arbitration are inherently unpredictable and legal proceedings related to these claims, individually or in the aggregate, could have a material impact on our business, financial condition, results of operations and cash flows. Regardless of the outcome, litigation and arbitration of these matters can have an adverse impact on us because of defense and settlement costs individually and in the aggregate, diversion of management resources and other factors. State Unemployment Taxes In 2018, the New Jersey Department of Labor (“NJDOL”) opened an audit reviewing whether Drivers were independent contractors or employees for purposes of determining whether unemployment insurance regulations apply from 2014 through 2018. The NJDOL made an assessment on November 12, 2019, against both Rasier and Uber. Both assessments were calculated through November 15, 2019, but only calculated the alleged contributions, penalties, and interests owed from 2014 through 2018. The NJDOL has provided several assessments from February through October 2021. We are engaged in ongoing discussions with the NJDOL about the assessments. While the ultimate resolution of this matter is uncertain, we recorded for this matter within accrued and other current liabilities on the condensed consolidated balance sheet as of September 30, 2021. Google v. Levandowski & Ron; Google v. Levandowski On October 28, 2016, Google filed arbitration demands against each of Anthony Levandowski and Lior Ron, former employees of Google, alleging breach of their respective employment agreements with Google, fraud and other state law violations (due to soliciting Google employees and starting a new venture to compete with Google’s business in contravention of their respective employment agreements). Google sought damages, injunctive relief, and restitution. On March 26, 2019, following a hearing, the arbitration panel issued an interim award, finding against each of Google’s former employees and awarding $127 million against Anthony Levandowski and $1 million for which both Anthony Levandowski and Lior Ron are jointly and severally liable. In July 2019, Google submitted its request for interest, attorneys fees, and costs related to these claims. The Panel’s Final Award was issued on December 6, 2019. On February 7, 2020, Ron and Google entered into a settlement agreement and mutual release to satisfy the corrected final award in the amount of approximately $10 million. Uber paid Google on behalf of Ron pursuant to an indemnification obligation. A dispute continues to exist with regard to Uber’s alleged indemnification obligation to Levandowski. Whether Uber is ultimately responsible for indemnification of Levandowski depends on the exceptions and conditions set forth in the indemnification agreement. In March 2020, Levandowski pleaded guilty to criminal trade secret charges and filed for bankruptcy. Uber filed a proof of claim in the bankruptcy court, and Levandowski additionally asserted a claim against Uber alleging that Uber failed to perform its obligations under an agreement with Otto Trucking, LLC. The indemnification dispute and Levandowski’s claim will proceed in the bankruptcy court. Former President Trump pardoned Levandowski from the trade secret conviction. The ultimate resolution of the matter could result in a possible loss of up to $60 million or more (depending on interest incurred) in excess of the amount accrued. Non-Income Tax Matters We recorded an estimated liability for contingencies related to non-income tax matters and are under audit by various domestic and foreign tax authorities with regard to such matters. The subject matter of these contingent liabilities and non-income tax audits primarily arises from our transactions with Drivers, as well as the tax treatment of certain employee benefits and related employment taxes. In jurisdictions with disputes connected to transactions with Drivers, disputes involve the applicability of transactional taxes (such as sales, value added and similar taxes) to services provided, as well as the applicability of withholding tax on payments made to such Drivers. We are involved in a proceeding in the UK involving HMRC, the tax regulator in the UK, which is seeking to classify us as a transportation provider. Being classified as a transportation provider would result in a VAT (20%) on Gross Bookings or on the service fee that we charge Drivers, both retroactively and prospectively. HMRC is considering a number of factors including our contractual Driver, Rider and intercompany arrangements, and HMRC is also expected to consider the U.K. Supreme Court’s February 19, 2021 ruling on Drivers’ worker classification, in determining whether we should be classified as a provider of transportation services. HMRC may update its assessment, which we would then review and discuss with HMRC. If we do not reach a satisfactory resolution after exhausting HMRC’s review and appeals process, we would still be able to argue our case anew in the U.K. Tax Court, which may require the up-front payment to the Tax Court (“pay-to-play”) of any final HMRC assessment to be held in escrow. We continue to believe that we have meritorious defense in these proceedings. Our estimated liability is inherently subjective due to the complexity and uncertainty of these matters and the judicial processes in certain jurisdictions, therefore, the final outcome could be different from the estimated liability recorded. Other Legal and Regulatory Matters We have been subject to various government inquiries and investigations surrounding the legality of certain of our business practices, compliance with antitrust, Foreign Corrupt Practices Act and other global regulatory requirements, labor laws, securities laws, data protection and privacy laws, and the infringement of certain intellectual property rights. We have investigated many of these matters and we are implementing a number of recommendations to our managerial, operational and compliance practices, as well as strengthening our overall governance structure. In many cases, we are unable to predict the outcomes and implications of these inquiries and investigations on our business which could be time consuming, costly to investigate and require significant management attention. Furthermore, the outcome of these inquiries and investigations could negatively impact our business, reputation, financial condition and operating results, including possible fines and penalties and requiring changes to operational activities and procedures. Indemnifications In the ordinary course of business, we often include standard indemnification provisions in our arrangements with third parties. Pursuant to these provisions, we may be obligated to indemnify such parties for losses or claims suffered or incurred in connection with their activities or non-compliance with certain representations and warranties made by us. In addition, we have entered into indemnification agreements with our officers, directors, and certain current and former employees, and our certificate of incorporation and bylaws contain certain indemnification obligations. It is not possible to determine the maximum potential loss under these indemnification provisions / obligations because of the unique facts and circumstances involved in each particular situation.

Variable Interest Entities

Variable Interest Entities	9 Months Ended
	Sep. 30, 2021
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Note 14 – Variable Interest Entities Variable interest entities (“VIEs”) are legal entities that lack sufficient equity to finance their activities without future subordinated financial support. Consolidated VIEs We consolidate VIEs in which we hold a variable interest and are the primary beneficiary. We are the primary beneficiary because we have the power to direct the activities that most significantly impact the economic performance of these VIEs. As a result, we consolidate the assets and liabilities of these VIEs. Total assets included on the condensed consolidated balance sheets for our consolidated VIEs as of December 31, 2020 and September 30, 2021 were $1.2 billion and $696 million, respectively. Total liabilities included on the condensed consolidated balance sheets for these VIEs as of December 31, 2020 and September 30, 2021 were not material. Freight Holding As of September 30, 2021, we own the majority of the issued and outstanding capital stock of Freight Holding and report a non-controlling interest as further described in Note 15 – Non-Controlling Interests. Divestiture of ATG Business and Aurora Investments As of December 31, 2020, we consolidated the ATG Business’ assets and liabilities and reported non-controlling interests. The common units held by us in the ATG Business were determined to be a variable interest. We determined that the ATG Business was a VIE as it lacked sufficient equity to finance its activities without future subordinated financial support. We had the power to direct the activities that most significantly impacted the economic performance of the ATG Business, and, as a result, we were the primary beneficiary of the ATG Business. On January 19, 2021, we completed the sale of the ATG Business to Aurora. Refer to the section titled “Unconsolidated VIEs” below for additional information on Aurora. Refer to Note 17 – Divestiture for further information on the sale of the ATG Business. Careem Qatar and Morocco The assets and operations in Careem Qatar and Morocco had not been transferred to us as of December 31, 2020. On September 21, 2021, ownership of Careem’s operations in Morocco was fully transferred to us. Transfer of the assets and operations of Careem Qatar will be subject to a delayed closing pending timing of regulatory approval. We have rights to all residual interests in the Careem Qatar entity which is considered a variable interest. We are exposed to losses and residual returns of the Careem Qatar entity through the right to all of the proceeds from either the divestiture or the eventual legal transfer, upon regulatory approval, of the Careem Qatar entity. Unconsolidated VIEs We do not consolidate VIEs in which we hold a variable interest but are not the primary beneficiary because we lack the power to direct the activities that most significantly impact the entities’ economic performance. Our carrying amount of assets recognized on the condensed consolidated balance sheets related to unconsolidated VIEs was $308 million and $2.8 billion as of December 31, 2020 and September 30, 2021, respectively, and represents our maximum exposure to loss associated with the unconsolidated VIEs. Zomato Zomato is incorporated in India with the purposes of providing food delivery services. On January 21, 2020, we acquired compulsorily convertible cumulative preference shares of Zomato in exchange for Uber’s food delivery operations in India (“Uber Eats India”), and a note receivable for reimbursement of goods and services tax. During the second quarter of 2021, the outstanding note receivable was paid. As of September 30, 2021, we determined Zomato is no longer a VIE as it is sufficiently capitalized as a result of its IPO in India during July 2021. Refer to Note 3 – Investments and Fair Value Measurement for further information. Lime Neutron Holdings, Inc. (“Lime”) is incorporated in Delaware for the purpose of owning and operating a fleet of dockless e-bikes and e-scooters for short-term access use by consumers for personal transportation. On May 7, 2020, we entered into a series of transactions and agreements with Lime to divest our JUMP business and acquired ownership in Lime comprised of Lime Common Stock, Lime 1-C Preferred Stock, Lime 1-C Preferred Stock Warrants, and the Lime Convertible Note (collectively, the “2020 Lime Investments”). We are exposed to Lime’s economic risks and rewards through our ownership of the 2020 Lime Investments, which represent variable interests. Cornershop: CS-Mexico As of December 31, 2020, Cornershop Cayman’s (“Cornershop”) business operations in Mexico (“CS-Mexico”) were determined to be a variable interest. We were exposed to CS-Mexico’s economic risks and rewards; however, we were not the primary beneficiary and we did not consolidate CS-Mexico. In December 2020, we received approval from Mexico’s antitrust regulator to complete the CS-Mexico transaction. On January 11, 2021, Cornershop Global (“CS-Global”), an entity which held all of Cornershop business operations, except for those in Mexico, exercised a call option and acquired 100% of the outstanding equity interest in CS-Mexico. We owned 55% of CS-Mexico through our ownership in CS-Global. The acquisition of CS-Mexico by CS-Global triggered a reconsideration event and we reevaluated if CS-Mexico still met the definition of a VIE. During the first quarter of 2021, we determined that CS-Mexico was no longer a VIE when it was acquired by CS-Global, which has sufficient equity to operate without the need for subordinated financial support. Refer to Note 16 – Business Combinations for further information. Aurora In January 2021, we sold our ATG Business to Aurora. After the sale, we hold equity interests in Aurora through our Aurora Investments. As of September 30, 2021, the fair value of our Aurora Investments was $2.3 billion and is included in investments on the condensed consolidated balance sheet. Refer Note 3 – Investments and Fair Value Measurement for additional information regarding the accounting for our Aurora Investments and Note 17 – Divestiture for additional information regarding the sale of our ATG Business. Aurora is a VIE as it lacks sufficient equity to finance its activities without future subordinated financial support. We are exposed to Aurora’s economic risks and rewards through our equity interests, which represent variable interests. Moove On February 12, 2021 (the “Moove Closing Date”), we entered into and completed a series of agreements with Garment Investments S.L. dba Moove (“Moove”) including (i) an equity investment, through preferred shares, in which Uber acquired a 30% minority interest in Moove from its current shareholders at closing and up to approximately $185 million contingent on future performance of Moove and certain other conditions through the eight Our equity investment in Moove, through preferred shares, is accounted for as an investment in non-marketable equity securities included in investments on the condensed consolidated balance sheet. The term loan, of $210 million as of September 30, 2021, is accounted for as a loan receivable, carried at amortized cost, and included in other assets on the condensed consolidated balance sheet. Refer to Note 3 – Investments and Fair Value Measurement, Assets Measured at Fair Value on a Non-Recurring Basis, for additional information regarding our non-marketable equity securities. Moove is a VIE as it lacks sufficient equity to finance its activities without future subordinated financial support. We are exposed to Moove’s economic risks and rewards through our equity investment, the term loan and commercial partnership agreement, which represent variable interests.

Noncontrolling Interest [Abstract]
Non-Controlling Interests	Note 15 – Non-Controlling Interests Freight Holding As of December 31, 2020, we owned 85% of the issued and outstanding capital stock of our subsidiary Freight Holding, or 79% on a fully-diluted basis if all shares reserved for issuance under our Freight Holding employee incentive plan were issued and outstanding. The minority stockholders of Freight Holding include: (i) holders of Freight Holding’s Series A Preferred Stock; (ii) holders of common equity awards issued under the employee equity incentive plans; and (iii) employees who hold fully vested shares. In July 2021, we entered into a Freight Series A Preferred Stock Purchase Agreement and sold shares of Freight Holding's Series A Preferred Stock to The Public Investment Fund, which is an investor in Uber, representing 4% ownership interest on a fully diluted basis. As of September 30, 2021, we owned 80% of the issued and outstanding capital stock of Freight Holding, or 75% on a fully-diluted basis if all shares reserved for issuance under our Freight Holding employee incentive plan were issued and outstanding. Cornershop As of December 31, 2020, we owned 55% of the outstanding membership interests in the issued and outstanding capital stock of CS-Global, or 52% on a fully-diluted basis. In December 2020, we received approval from Mexico’s antitrust regulator to complete the CS-Mexico transaction. On January 11, 2021, CS-Global exercised a call option and acquired 100% of the outstanding equity interest in CS-Mexico, which increased the redeemable non-controlling interest. We owned 55% of CS-Mexico through our ownership interest in CS-Global. As of December 31, 2020, Cornershop’s financial results are consolidated in our consolidated financial statements given our majority ownership interest. In August 2021, we acquired the minority shareholders' interests in CS-Global in an all-stock transaction and CS-Global became a wholly-owned subsidiary of ours. We derecognized the carrying value of redeemable non-controlling interests in CS-Global of $1.3 billion. Refer to Note 16 – Business Combinations for further information. Divestiture of ATG Business to Aurora On January 19, 2021, we completed the previously announced sale of our ATG Business to Aurora. As a result, our controlling interest and the non-controlling interests in the ATG Business were settled and ownership of the ATG Business transferred to Aurora. We derecognized the carrying value of non-controlling interests in the ATG Business of $1.1 billion, which included Toyota Motor North America, Inc. and DENSO International America, Inc. non-redeemable non-controlling interests of $701 million and SVF Yellow (USA) Corporation’s (or “Softbank’s”) redeemable non-controlling interests of $356 million .

Business Combinations

Business Combination and Asset Acquisition [Abstract]
Business Combinations	Note 16 – Business Combinations Careem During the first quarter of 2020, we completed the acquisition of substantially all of the assets of Careem for approximately $3.0 billion. Dubai-based Careem provides primarily ridesharing and to a lesser extent meal delivery, and payments services to millions of users in cities across the Middle East, North Africa, and Pakistan. On September 21, 2021, ownership of Careem’s operations in Morocco were fully transferred to us. As of September 30, 2021, ownership of Careem’s operations in Qatar had not yet been transferred to us; however the results of operations and net assets were fully consolidated as variable interest entity. As part of the acquisition, we agreed to issue the Careem Notes with an acquisition date fair value of $1.6 billion in different tranches with $880 million of the principal amount of the Careem Notes issued as of January 2, 2020 and settled in cash on April 1, 2020. Each tranche of the Careem Notes is due and payable 90 days once issued. The holders of the Careem Notes may elect to convert the full outstanding principal balance to common stock at a conversion price of $55 per share of Uber Technologies, Inc. at any time prior to maturity. During the three months ended September 30, 2021, none of the holders of the Careem Notes elected to convert their notes. During the nine months ended September 30, 2021, certain holders of the Careem Notes elected to convert their notes and as a result of such elections, $427 million of the principal amount of the Careem Notes matured, of which $195 million were settled in cash and $232 million were settled in equity. The remaining amount of the Careem Notes is recognized as a commitment to issue unsecured convertible notes at fair value in accrued and other current liabilities of $115 million and in other long-term liabilities $122 million as of September 30, 2021. The discount from the Careem Notes face value to fair value will be accreted through the respective repayment dates as interest expense. The amount of accretion for the three and nine months ended September 30, 2021 was not material. Cornershop During the third quarter of 2020, we acquired a 55% controlling interest in the Cornershop Global (“CS-Global”), an entity which held all of Cornershop Cayman’s (“Cornershop”) business operations, except for those in Mexico. Cornershop operates as an online grocery delivery platform primarily in Chile and Mexico. Uber and CS-Global also entered into a put/call arrangement over the non-controlling interest in CS-Global, providing Uber the right and obligation to acquire the remaining interest from non-controlling interest holders, exercisable in 5 years if there is no IPO or liquidation event, at a future negotiated price. Concurrent with the CS-Global acquisition transaction, Uber, Cornershop and CS-Global entered into a put/call agreement providing CS-Global with the right through the call option (and obligation through the put option held by Cornershop) to purchase all of the interests in CS-Mexico, contingent upon the receipt of regulatory approval in Mexico (“CS-Mexico Put/Call”). Upon either the exercise of the call option (by CS-Global) or the put option (by Cornershop), CS-Global would acquire 100% of the outstanding equity interests in CS-Mexico. In December 2020, we received approval from Mexico’s antitrust regulator to complete the CS-Mexico transaction. On January 11, 2021, CS-Global exercised the call option through the CS-Mexico Put/Call agreement and acquired 100% of the outstanding equity interest in CS-Mexico, and we owned 55% of CS-Mexico through our ownership in CS-Global. The acquisition of CS-Mexico was accounted for as a business combination. The acquisition date fair value of the consideration transferred for CS-Mexico was immaterial, and consisted of a combination of cash payment and equity payment in Uber common stock and the fair value of the CS-Mexico Put/Call remeasured at the acquisition date. As a result of remeasuring our prior CS-Mexico Put/Call held immediately prior to the business combination, we recognized an immaterial loss during the nine months ended September 30, 2021. The loss was included in other income (expense), net in the condensed consolidated statements of operations. In August 2021, we completed the acquisition of the remaining 45% ownership interest in Cornershop (or 47%, on a fully-diluted basis) in an all-stock transaction. As consideration for our acquisition of the remaining non-controlling interest, we issued 25 million shares of our common stock, including 4.6 million restricted shares issued to certain Cornershop employees. In addition, we issued 4 million stock options to replace assumed outstanding stock options. These replacement stock options attributable to post-acquisition service are included in our option activity and will be recognized as stock-based compensation expense. The acquisition was accounted for as an equity transaction, as we previously controlled and consolidated Cornershop. Accordingly, we did not recognize a gain or loss in our condensed consolidated statements of operations during the three months ended September 30, 2021. In connection with this acquisition, the previously recognized non-controlling interest was derecognized. Following this transaction, Cornershop became our wholly-owned subsidiary. The total purchase price was determined to be $967 million, based on the number of shares issued and Uber’s share price on the closing date. The fair value of the 4.6 million restricted shares issued to certain Cornershop employees was determined to be $202 million. These shares are restricted and contingent on the employees’ continuing employment at the combined company for the next three years. These restricted shares are considered compensation for post-combination services and will be recognized as stock-based compensation expense ratably over the next three years. Postmates On December 1, 2020, we completed the acquisition of Postmates, Inc. (“Postmates”), an on-demand delivery platform in the U.S. by acquiring 100% ownership interest in Postmates for a total consideration of approximately $3.9 billion. During the first quarter of 2021, we recorded a measurement period adjustment of $170 million to accrued and other current liabilities with a corresponding increase to goodwill, based on facts and circumstances in existence as of the effective date of the acquisition. Refer to Note 13 – Commitments and Contingencies for further information.

Discontinued Operations and Disposal Groups [Abstract]
Divestiture	Note 17 – Divestiture Divestiture of ATG Business to Aurora On January 19, 2021, we completed the previously announced sale of our ATG Business, a subsidiary focused on the development and commercialization of autonomous vehicle technology, to Aurora. As a result, our controlling interest and the non-controlling interests in the ATG Business were settled, and ownership of the ATG Business transferred to Aurora. As consideration for the sale, Aurora issued Series U-1 preferred shares to the third party investors of the ATG Business to settle their ATG Series A Stated Liquidation Preference of $1.1 billion, which had previously been recorded as redeemable and non-redeemable non-controlling interests on our condensed consolidated balance sheet prior to this transaction. We received the residual consideration from the sale as the only common unit holder of the ATG Business in the form of Aurora common shares valued at $1.3 billion, representing 22% of fully-diluted (25% undiluted) ownership interest of Aurora. Concurrently, we invested $400 million in Aurora in exchange for Aurora Series U-2 convertible preferred shares, representing 4% of fully-diluted (5% undiluted) ownership interest of Aurora. Refer to Note 3 – Investments and Fair Value Measurement for additional information. We do not consolidate Aurora under either the VIE or the voting interest model. For further information, refer to Note 14 – Variable Interest Entities. We entered into a commercial agreement with Aurora pursuant to which the parties will collaborate with best efforts to launch and commercialize self-driving vehicles on our ridesharing network. We also allowed unvested RSUs for Uber stock held by employees of the ATG Business that transferred to Aurora to continue to vest over the next 12 months contingent upon the employee remaining at Aurora. As a result, we recognized liabilities of $315 million as consideration for these future obligations to Aurora. The sale of the ATG Business did not represent a strategic shift that would have had a major effect on our operations and financial results, and therefore does not qualify for reporting as a discontinued operation. The resulting gain on disposal was recorded in other income (expense), net in the condensed consolidated statement of operations. After the sale of the ATG Business, Aurora is considered a related party. The following table presents the gain on sale of the ATG Business (in millions): Three Months Ended Fair value of common shares received $ 1,277 Derecognition of ATG Business' non-controlling interests 1,057 Liability recognized for future obligations (315) Net consideration received for sale of the ATG Business 2,019 Carrying value of net assets transferred (375) Gain on the sale of the ATG Business $ 1,644

Subsequent Events	Note 18 – Subsequent Events Investment in Freight On November 4, 2021, we entered into a preferred stock purchase agreement with new investors (“New Freight Investors”). Pursuant to the preferred stock purchase agreement, the New Freight Investors agreed to invest an aggregate of $550 million in Freight Holding, the holding company for our Uber Freight business, in exchange for Series A-1 convertible preferred stock of Freight Holding. The purchase and sale of the convertible preferred stock shall take place concurrently and is contingent upon closing of the previously announced Transplace acquisition. The remainder of the Transplace purchase price will be funded by the net proceeds from the 2029 Senior Notes and cash. Acquisition of Drizly On October 12, 2021, we completed the acquisition of The Drizly Group, Inc. (“Drizly”). Drizly operates an on-demand alcohol marketplace in North America. We are currently evaluating purchase price allocation. It is not practicable to disclose the preliminary purchase price allocation for this acquisition given the short period of time between the acquisition date and the issuance of these condensed consolidated financial statements. We issued approximately 18.9 million shares of common stock and paid an immaterial amount in cash as consideration to close this transaction.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The condensed consolidated balance sheet as of December 31, 2020 included herein was derived from the audited consolidated financial statements as of that date. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2020, included in our Annual Report on Form 10-K. The results for the interim periods are not necessarily indicative of results for the full year. In the opinion of management, these financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair statement of the financial position, results of operations, comprehensive loss, cash flows and the change in equity for the periods presented. There have been no changes to our significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on March 1, 2021 that have had a material impact on our condensed consolidated financial statements and related notes, except for an update reflecting the new accounting standard related to debt with conversion and other options.
Basis of Consolidation	Basis of ConsolidationOur condensed consolidated financial statements include the accounts of Uber Technologies, Inc. and entities consolidated under the variable interest and voting models. All intercompany balances and transactions have been eliminated. Refer to Note 14 – Variable Interest Entities for further information.
Use of Estimates	Use of Estimates The preparation of our unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions, which affect the reported amounts in the financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions which management believes are reasonable under the circumstances. On an ongoing basis, management evaluates estimates, including, but not limited to: the incremental borrowing rate (“IBR”) applied in lease accounting; fair values of investments and other financial instruments (including the measurement of credit or impairment losses); useful lives of long-lived assets; fair value of acquired intangible assets and related impairment assessments; impairment of goodwill; stock-based compensation; income taxes and non-income tax reserves; certain deferred tax assets and tax liabilities; insurance reserves; and other contingent liabilities. These estimates are inherently subject to judgment and actual results could differ from those estimates. The level of uncertainties and volatility in the global financial markets and economies resulting from the pandemic as well as the uncertainties related to the impact of the pandemic on us and our investees' operations and financial performance means that these estimates may change in future periods, as new events occur and additional information is obtained.
Certain Significant Risks and Uncertainties - COVID-19	Certain Significant Risks and Uncertainties - COVID-19 Various governments continue to implement, lift, and in some regions reinstate restrictions, including business activities and travel restrictions. These restrictions have had an adverse impact on our business and operations by reducing, in particular, the global demand for Mobility offerings, while accelerating the growth of our Delivery offerings. COVID-19 has produced uncertainty around the world and it is not possible to predict the COVID-19 pandemic’s cumulative and ultimate impact on our future business operations, results of operations, financial position, liquidity, and cash flows. The extent of the impact of the pandemic on our business and financial results will depend largely on future developments, including the duration of the spread of the outbreak and any resurgences of the outbreak or variants of the virus, both globally and within the United States, the administration, adoption and efficacy of vaccines in the United States and internationally, the impact on capital, foreign currencies exchange and financial markets, governmental or regulatory orders that impact our business and whether the impacts may result in permanent changes to our end-users’ behavior, all of which are highly uncertain and cannot be predicted.
Collateral Held by Insurer	Collateral Held by Insurer Collateral held by insurer represents funds held by James River Group companies (“James River”). These funds, previously held in a trust account, were withdrawn by James River during the fourth quarter of 2019 upon notice of cancellation of their insurance policies (primarily auto insurance policies) issued to one of our subsidiaries. As of December 31, 2020, the funds served as collateral for us and our subsidiary’s current and future claim settlement obligations under the indemnification agreements for these insurance policies as included in insurance reserves on the condensed consolidated balance sheet . Accordingly, the amount withdrawn is presented as collateral held by insurer on the condensed consolidated balance sheet a s of December 31, 2020.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In January 2020, the FASB issued ASU 2020-01, “Investments-Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815,” which clarifies the interaction of the accounting for equity investments under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. We adopted the new standard on January 1, 2021 on a prospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In August 2020, the FASB issued 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,” which reduced the number of models used to account for convertible instruments, amends the accounting for certain contracts in an entity’s own equity that would have previously been accounted for as derivatives and modifies the diluted earnings per share calculations for convertible instruments. We early adopted the new standard on January 1, 2021 on a modified retrospective basis. Refer to Note 7 – Long-Term Debt and Revolving Credit Arrangements for the impact of adoption on our 2025 Convertible Notes and Note 11 – Net Income (Loss) Per Share for the impact on our earnings per share calculation. Recently Issued Accounting Pronouncements Not Yet Adopted In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides optional expedients and exceptions to contract modifications and hedging relationships that reference LIBOR or another reference rate expected to be discontinued. The standard is effective upon issuance through December 31, 2022 and may be applied at the beginning of the interim period that includes March 12, 2020 or any date thereafter. We are currently evaluating the impact of this accounting standard update on our consolidated financial statements.
Net Income (Loss) Per Share	Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding for the periods presented. Diluted net income (loss) per share is computed by giving effect to all potential weighted average dilutive common stock. The dilutive effect of outstanding awards and convertible securities is reflected in diluted net income (loss) per share by application of the treasury stock method. Since we were in a loss position for each of the periods presented, basic net loss per share was the same as diluted net loss per share for the periods presented. We take into account the effect on consolidated net income (loss) per share of dilutive securities of entities in which we hold equity interests that are accounted for using the equity method.
