Trips during the quarter grew 19% YoY to 1.95 billion, or approximately 21 million trips per day on average.
• Revenue grew 72% YoY to $8.3 billion, or 81% on a constant currency basis, with Revenue growth significantly outpacing Gross Bookings growth due to the acquisition of Transplace by Uber Freight and a change in the business model for our UK Mobility business.
• Net loss attributable to Uber Technologies, Inc. was $1.2 billion, which includes a $512 million net headwind (pre-tax) primarily due to net unrealized losses related to the revaluations of Uber’s equity investments.

"Strong demand for our offerings, better marketplace efficiency, and our asset-light platform helped to deliver Adjusted EBITDA well above our guidance, even as foreign exchange and inflationary headwinds impact all global businesses,” said Nelson Chai, CFO. “We remain focused on excellent execution and disciplined cost management to deliver on our growth and profitability commitments for the coming years.”

• Revenue of $3.8 billion: Mobility Revenue grew 73% YoY and 8% QoQ. The YoY increase was primarily driven by a $1.1 billion benefit related to a UK business model change that classifies most driver payments and incentives as cost of revenue. Mobility Take Rate of 27.9% increased 560 bps YoY and 130 bps QoQ. The UK business model change impacting revenue represented a 770 bps net benefit to Take Rate in the quarter. Additionally, Mobility Take Rate was adversely impacted by pass-through fuel surcharges implemented through Q3 2022 in various markets globally.
• Adjusted EBITDA of $898 million: Mobility Adjusted EBITDA increased $354 million YoY and $127 million QoQ. Mobility Adjusted EBITDA margin was 6.6% of Gross Bookings compared to 5.5% in Q3 2021 and 5.8% in Q2 2022. Mobility Adjusted EBITDA margin improvement YoY was primarily driven by better cost leverage from higher volume, and a meaningful reduction in driver supply investments.

Non-GAAP Financial Measures

To supplement our financial information, which is prepared and presented in accordance with generally accepted accounting principles in the United States of America (“GAAP”), we use the following non-GAAP financial measures: Adjusted EBITDA; Free cash flow; Non-GAAP Costs and Operating Expenses as well as, revenue growth rates in constant currency. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. We use these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance by excluding certain items that may not be indicative of our recurring core business operating results.

We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, and analyzing future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to our historical performance. We believe these non-GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making and (2) they are used by our institutional investors and the analyst community to help them analyze the health of our business.

There are a number of limitations related to the use of non-GAAP financial measures. In light of these limitations, we provide specific information regarding the GAAP amounts excluded from these non-GAAP financial measures and evaluating these non-GAAP financial measures together with their relevant financial measures in accordance with GAAP.

For more information on these non-GAAP financial measures, please see the sections titled “Key Terms for Our Key Metrics and Non-GAAP Financial Measures,” “Definitions of Non-GAAP Measures” and “Reconciliations of Non-GAAP Measures” included at the end of this release. In regards to forward looking guidance, we are not able to reconcile the forward-looking non-GAAP Adjusted EBITDA measure to the closest corresponding GAAP measure without unreasonable efforts because we are unable to predict the ultimate outcome of certain significant items. These items include, but are not limited to, significant legal settlements, unrealized gains and losses on equity investments, tax and regulatory reserve changes, restructuring costs and acquisition and financing related impacts.

Other Income (Expense), Net

The following table presents components of other income (expense), net (in millions):

Key Terms for Our Key Metrics and Non-GAAP Financial Measures

Adjusted EBITDA. Adjusted EBITDA is a Non-GAAP measure. We define Adjusted EBITDA as net income (loss), excluding (i) income (loss) from discontinued operations, net of income taxes, (ii) net income (loss) attributable to non-controlling interests, net of tax, (iii) provision for (benefit from) income taxes, (iv) income (loss) from equity method investments, (v) interest expense, (vi) other income (expense), net, (vii) depreciation and amortization, (viii) stock-based compensation expense, (ix) certain legal, tax, and regulatory reserve changes and settlements, (x) goodwill and asset impairments/loss on sale of assets, (xi) acquisition, financing and divestitures related expenses, (xii) restructuring and related charges and (xiii) other items not indicative of our ongoing operating performance, including COVID-19 response initiatives related payments for financial assistance to Drivers personally impacted by COVID-19, the cost of personal protective equipment distributed to Drivers, Driver reimbursement for their cost of purchasing personal protective equipment, the costs related to free rides and food deliveries to healthcare workers, seniors, and others in need as well as charitable donations. Our board and management find the exclusion of the impact of these COVID-19 response initiatives from Adjusted EBITDA to be useful because it allows us and our investors to assess the impact of these response initiatives on our results of operations.

Adjusted EBITDA margin. We define Adjusted EBITDA margin as Adjusted EBITDA as a percentage of Gross Bookings.

COVID-19 response initiatives. To support those whose earning opportunities have been depressed as a result of COVID-19, as well as communities hit hard by COVID-19, we implemented several initiatives, including, in particular, payments for financial assistance to Drivers personally impacted by COVID-19, the cost of personal protective equipment distributed to Drivers, Driver reimbursement for their cost of purchasing personal protective equipment, the costs related to free rides and food deliveries to healthcare workers, seniors, and others in need as well as charitable donations. The payments for financial assistance to Drivers personally impacted by COVID-19 and Driver reimbursement for their cost of purchasing personal protective equipment are recorded as a reduction to revenue. The cost of personal protective equipment distributed to Drivers, the costs related to free rides and food deliveries to healthcare workers, seniors, and others in need as well as charitable donations are recorded as an expense in our costs and expenses.

Driver(s). The term Driver collectively refers to independent providers of ride or delivery services who use our platform to provide Mobility or Delivery services, or both.

Driver or restaurant earnings. Driver or restaurant earnings refer to the net portion of the fare or the net portion of the order value that a Driver or a restaurant retains, respectively.

Driver incentives. Driver incentives refer to payments that we make to Drivers, which are separate from and in addition to the Driver’s portion of the fare paid by the consumer after we retain our service fee to Drivers. For example, Driver incentives could include payments we make to Drivers should they choose to take advantage of an incentive offer and complete a consecutive number of trips or a cumulative number of trips on the platform over a defined period of time. Driver incentives are recorded as a reduction of revenue.

Free cash flow. Free cash flow is a Non-GAAP measure. We define free cash flow as net cash flows from operating activities less capital expenditures.

Gross Bookings. We define Gross Bookings as the total dollar value, including any applicable taxes, tolls, and fees, of: Mobility rides; Delivery orders (in each case without any adjustment for consumer discounts and refunds); Driver and Merchant earnings; Driver incentives and Freight revenue. Gross Bookings do not include tips earned by Drivers.

Monthly Active Platform Consumers (“MAPCs”). We define MAPCs as the number of unique consumers who completed a Mobility or New Mobility ride or received a Delivery order on our platform at least once in a given month, averaged over each month in the quarter. While a unique consumer can use multiple product offerings on our platform in a given month, that unique consumer is counted as only one MAPC.

Segment Adjusted EBITDA. We define each segment’s Adjusted EBITDA as segment revenue less the following direct costs and expenses of that segment: (i) cost of revenue, exclusive of depreciation and amortization; (ii) operations and support; (iii) sales and marketing; (iv) research and development; and (v) general and administrative. Segment Adjusted EBITDA also reflects any applicable exclusions from Adjusted EBITDA.

Segment Adjusted EBITDA margin. We define each segment’s Adjusted EBITDA margin as the segment Adjusted EBITDA as a percentage of segment Gross Bookings.

Take Rate. We define Take Rate as revenue as a percentage of Gross Bookings.

Trips. We define Trips as the number of completed consumer Mobility or New Mobility rides and Delivery orders in a given period. For example, an UberX Share ride with three paying consumers represents three unique Trips, whereas an UberX ride with three passengers represents one Trip.

Definitions of Non-GAAP Measures

We collect and analyze operating and financial data to evaluate the health of our business and assess our performance. In addition to revenue, net income (loss), income (loss) from operations, and other results under GAAP, we use: Adjusted EBITDA; Free cash flow; Non-GAAP Costs and Operating Expenses; as well as, revenue growth rates in constant currency, which are described below, to evaluate our business. We have included these non-GAAP financial measures because they are key measures used by our management to evaluate our operating performance. Accordingly, we believe that these non-GAAP financial measures provide useful information to investors and others in understanding and evaluating our operating results in the same manner as our management team and board of directors. Our calculation of these non-GAAP financial measures may differ from similarly-titled non-GAAP measures, if any, reported by our peer companies. These non-GAAP financial measures should not be considered in isolation from, or as substitutes for, financial information prepared in accordance with GAAP.

Adjusted EBITDA

We define Adjusted EBITDA as net income (loss), excluding (i) income (loss) from discontinued operations, net of income taxes, (ii) net income (loss) attributable to non-controlling interests, net of tax, (iii) provision for (benefit from) income taxes, (iv) income (loss) from equity method investments, (v) interest expense, (vi) other income (expense), net, (vii) depreciation and amortization, (viii) stock-based compensation expense, (ix) certain legal, tax, and regulatory reserve changes and settlements, (x) goodwill and asset impairments/loss on sale of assets, (xi) acquisition, financing and divestitures related expenses, (xii) restructuring and related charges and (xiii) other items not indicative of our ongoing operating performance, including COVID-19 response initiatives related payments for financial assistance to Drivers personally impacted by COVID-19, the cost of personal protective equipment distributed to Drivers, Driver reimbursement for their cost of purchasing personal protective equipment, the costs related to free rides and food deliveries to healthcare workers, seniors, and others in need as well as charitable donations.

We have included Adjusted EBITDA because it is a key measure used by our management team to evaluate our operating performance, generate future operating plans, and make strategic decisions, including those relating to operating expenses. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management team and board of directors. In addition, it provides a useful measure for period-to-period comparisons of our business, as it removes the effect of certain non-cash expenses and certain variable charges. To help our board, management and investors assess the impact of COVID-19 on our results of operations, we are excluding the impacts of COVID-19 response initiatives related payments for financial assistance to Drivers personally impacted by COVID-19, the cost of personal protective equipment distributed to Drivers, Driver reimbursement for their cost of purchasing personal protective equipment, the costs related to free rides and food deliveries to healthcare workers, seniors, and others in need as well as charitable donations from Adjusted EBITDA. Our board and management find the exclusion of the impact of these COVID-19 response initiatives from Adjusted EBITDA to be useful because it allows us and our investors to assess the impact of these response initiatives on our results of operations.

Adjusted EBITDA has limitations as a financial measure, should be considered as supplemental in nature, and is not meant as a substitute for the related financial information prepared in accordance with GAAP. These limitations include the following:

• Adjusted EBITDA excludes certain recurring, non-cash charges, such as depreciation of property and equipment and amortization of intangible assets, and although these are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect all cash capital expenditure requirements for such replacements or for new capital expenditure requirements;
• Adjusted EBITDA excludes certain restructuring and related charges, part of which may be settled in cash;
• Adjusted EBITDA excludes stock-based compensation expense, which has been, and will continue to be for the foreseeable future, a significant recurring expense in our business and an important part of our compensation strategy;
• Adjusted EBITDA excludes other items not indicative of our ongoing operating performance, including COVID-19 response initiatives related payments for financial assistance to Drivers personally impacted by COVID-19, the cost of personal protective equipment distributed to Drivers, Driver reimbursement for their cost of purchasing personal protective equipment, the costs related to free rides and food deliveries to healthcare workers, seniors, and others in need as well as charitable donations;
• Adjusted EBITDA does not reflect period to period changes in taxes, income tax expense or the cash necessary to pay income taxes;
• Adjusted EBITDA does not reflect the components of other income (expense), net, which primarily includes: interest income; foreign currency exchange gains (losses), net; gain (loss) on business divestitures, net; unrealized gain (loss) on debt and equity securities, net; and impairment of debt and equity securities; and
• Adjusted EBITDA excludes certain legal, tax, and regulatory reserve changes and settlements that may reduce cash available to us.

Constant Currency

We compare the percent change in our current period results from the corresponding prior period using constant currency disclosure. We present constant currency growth rate information to provide a framework for assessing how our underlying revenue performed excluding the effect of foreign currency rate fluctuations. We calculate constant currency by translating our current period financial results using the corresponding prior period’s monthly exchange rates for our transacted currencies other than the U.S. dollar.

Non-GAAP Costs and Operating Expenses

Costs and operating expenses are defined as: cost of revenue, exclusive of depreciation and amortization; operations and support; sales and marketing; research and development; and general and administrative expenses. We define Non-GAAP costs and operating expenses as costs and operating expenses excluding: (i) stock-based compensation expense, (ii) certain legal, tax, and regulatory reserve changes and settlements, (iii) goodwill and asset impairments/loss on sale of assets, (iv) certain acquisition, financing and divestiture related expenses, (v) restructuring and related charges and (vi) other items not indicative of our ongoing operating performance, including COVID-19 response initiative related payments for financial assistance to Drivers personally impacted by COVID-19, the cost of personal protective equipment distributed to Drivers, Driver reimbursement for their cost of purchasing personal protective equipment, the costs related to free rides and food deliveries to healthcare workers, seniors, and others in need as well as charitable donations.
