• Gross Bookings grew 19% year-over-year and 26% year-over-year on a constant currency basis
• Mobility Gross Bookings, Adjusted EBITDA and Adjusted EBITDA margin at all-time quarterly highs

Uber Technologies, Inc. (NYSE: UBER) today announced financial results for the quarter and full year ended December 31, 2022.

Financial Highlights for Fourth Quarter 2022

• Gross Bookings grew 19% year-over-year (“YoY”) to $30.7 billion, or 26% on a constant currency basis, with Mobility Gross Bookings of $14.9 billion (+31% YoY or +37% YoY constant currency) and Delivery Gross Bookings of $14.3 billion (+6% YoY or +14% YoY constant currency). Trips during the quarter grew 19% YoY to 2.1 billion, an all-time quarterly high, or approximately 23 million trips per day on average.
• Revenue grew 49% YoY to $8.6 billion, or 59% on a constant currency basis, with Revenue growth significantly outpacing Gross Bookings growth due to a change in the business model for our UK Mobility business and the acquisition of Transplace by Uber Freight.
• Net income attributable to Uber Technologies, Inc. was $595 million, which includes a $756 million net benefit (pre-tax) primarily due to net unrealized gains related to the revaluation of Uber’s equity investments.
• Adjusted EBITDA of $665 million, up $579 million YoY. Adjusted EBITDA margin as a percentage of Gross Bookings was 2.2%, up from 0.3% in Q4 2021. Incremental margin as a percentage of Gross Bookings was 11.9% YoY.
• Net cash used in operating activities was $244 million and free cash flow, defined as net cash flows from operating activities less capital expenditures, was $(303) million. Through 2022, net cash provided by operating activities was $642 million, and free cash flow was $390 million. Net cash from operating activities and free cash flow during Q4 2022 and full year 2022 were impacted by a cash outflow of approximately $733 million (GBP 613 million), related to the previously disclosed HMRC VAT claims settlement in the UK. Excluding this settlement, free cash flow would have been $430 million and $1.1 billion in Q4 2022 and full year 2022, respectively.
• Unrestricted cash, cash equivalents, and short-term investments were $4.3 billion at the end of the fourth quarter.

“We ended 2022 with our strongest quarter ever, with robust demand and record margins,” said Dara Khosrowshahi, CEO. “Our global scale and unique platform advantages position us well to accelerate this momentum into 2023.”

"In 2022, we significantly exceeded our profitability outlook, with an incremental margin of 10%,” said Nelson Chai, CFO. “Our outlook for a Gross Bookings and Adjusted EBITDA step up in Q1 builds on that progress, and sets us up for yet another record year."

Outlook for Q1 2023

For Q1 2023, we anticipate:

• Gross Bookings to grow 20% to 24% YoY on a constant currency basis, with an expected 3 percentage point currency headwind, translating to a range of $31.0 billion to $32.0 billion
• Adjusted EBITDA of $660 million to $700 million

Financial Highlights for the Fourth Quarter 2022 (continued)

Mobility

• Gross Bookings of $14.9 billion: Mobility Gross Bookings grew 37% YoY on a constant currency basis. On a sequential basis, Mobility Gross Bookings grew 9% quarter-over-quarter (“QoQ”), with growth in all geographic regions.
• Revenue of $4.1 billion: Mobility Revenue grew 82% YoY and 8% QoQ. The YoY increase was primarily driven by a $1.2 billion benefit related to a UK business model change that classifies most driver payments and incentives as cost of revenue. Mobility Take Rate of 27.8% increased 770 bps YoY and decreased 10 bps QoQ. The UK business model change impacting revenue represented an 800 bps net benefit to Take Rate in the quarter. Additionally, Mobility Take Rate was adversely impacted by pass-through fuel surcharges implemented through Q4 2022 in various markets globally.
• Adjusted EBITDA of $1.0 billion: Mobility Adjusted EBITDA increased $437 million YoY and $114 million QoQ. Mobility Adjusted EBITDA margin was 6.8% of Gross Bookings compared to 5.1% in Q4 2021 and 6.6% in Q3 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.

Delivery

• Gross Bookings of $14.3 billion: Delivery Gross Bookings grew 14% YoY on a constant currency basis. Delivery Gross Bookings in US & Canada were up 14% YoY and in all other markets were up 15% YoY on a constant currency basis.
• Revenue of $2.9 billion: Delivery Revenue grew 21% YoY and 6% QoQ. Take Rate of 20.5% grew 250 bps YoY and grew 30 bps QoQ. Business model changes in some countries that classify certain payments and incentives as cost of revenue benefited Delivery Take Rate by 480 bps in the quarter (compared to 410 bps benefit in Q4 2021 and 500 bps benefit in Q3 2022).
• Adjusted EBITDA of $241 million: Delivery Adjusted EBITDA grew $216 million YoY and $60 million QoQ, driven by higher volumes, increased Advertising revenue, and improved network efficiencies. Delivery Adjusted EBITDA margin as a percentage of Gross Bookings reached 1.7%, compared to 0.2% in Q4 2021 and 1.3% in Q3 2022.

Freight

• Revenue of $1.5 billion: Freight Revenue grew 43% YoY and declined 12% QoQ. Freight Revenue includes contributions from the acquisition of Transplace which closed on November 12, 2021.
• Adjusted EBITDA loss of $8 million: Freight Adjusted EBITDA grew $17 million YoY but declined $9 million QoQ. Freight Adjusted EBITDA margin as a percentage of Gross Bookings improved 1.8 percentage points YoY to (0.5)% driven by increased marketplace efficiency on our digital platform and strong sales momentum in our Transportation Management business.

Corporate

• Corporate G&A and Platform R&D: Corporate G&A and Platform R&D expenses of $580 million, compared to $489 million in Q4 2021, and $564 million in Q3 2022. On a YoY basis, Corporate G&A and Platform R&D remained flat as a percentage of Gross Bookings.

GAAP and Non-GAAP Costs and Operating Expenses

• Cost of revenue excluding D&A: GAAP cost of revenue equaled non-GAAP cost of revenue and was $5.3 billion, representing 17.3% of Gross Bookings, compared to 12.0% and 17.7% in Q4 2021 and Q3 2022, respectively. On a YoY basis, non-GAAP cost of revenue as a percentage of Gross Bookings increased due to the classification of certain Delivery and Mobility payments as cost of revenue attributable to business model changes in some countries and the acquisition of Transplace.
• GAAP and Non-GAAP operating expenses (Non-GAAP operating expenses exclude certain amounts as further detailed in the “Reconciliations of Non-GAAP Measures” section):
  • Operations and support: GAAP operations and support was $605 million. Non-GAAP operations and support was $564 million, representing 1.8% of Gross Bookings, compared to 2.0% in both Q4 2021 and Q3 2022. On a YoY basis, non-GAAP operations and support as a percentage of Gross Bookings decreased due to improved fixed cost leverage.
  • Sales and marketing: GAAP sales and marketing was $1.1 billion. Non-GAAP sales and marketing was $1.1 billion, representing 3.6% of Gross Bookings, compared to 4.8% and 3.9% in Q4 2021 and Q3 2022, respectively. On a YoY basis, non-GAAP sales and marketing as a percentage of Gross Bookings decreased due to a decrease in consumer discounts, rider facing loyalty expense, promotions, credits and refunds.
  • Research and development: GAAP research and development was $747 million. Non-GAAP research and development was $452 million, representing 1.5% of Gross Bookings, compared to 1.4% and 1.6% in Q4 2021 and Q3 2022, respectively. As a percentage of Gross Bookings, non-GAAP research and development increased on a YoY basis due to higher employee costs, but decreased on a QoQ basis with slower headcount growth.
  • General and administrative: GAAP general and administrative was $745 million. Non-GAAP general and administrative was $523 million, representing 1.7% of Gross Bookings, compared to 1.8% and 1.7% in Q4 2021 and Q3 2022, respectively. On a YoY basis, non-GAAP general and administrative as a percentage of Gross Bookings decreased due to improved fixed cost leverage.

About Uber

Uber’s mission is to create opportunity through movement. We started in 2010 to solve a simple problem: how do you get access to a ride at the touch of a button? More than 37 billion trips later, we're building products to get people closer to where they want to be. By changing how people, food, and things move through cities, Uber is a platform that opens up the world to new possibilities.

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; Free cash flow, excluding HMRC VAT claims settlement; 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 non-GAAP 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

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. We define incremental margin as the change in Adjusted EBITDA between periods divided by the change in Gross Bookings between periods.

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 or cost of revenue, exclusive of depreciation and amortization.

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.

Free cash flow, excluding HMRC VAT claims settlement. Free cash flow, excluding HMRC VAT claims settlement, is a Non-GAAP measure. We define Free cash flow, excluding HMRC VAT claims settlement as free cash flow excluding the Q4 2022 impact of the cash outflow of approximately $733 million (GBP 613 million) related to the settlement of outstanding HMRC VAT claims for periods prior to our UK business model change on March 14, 2022.

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; Free cash flow, excluding HMRC VAT claims settlement; 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 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 certain restructuring and related charges, part of which may be settled in cash;
• 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.

Free Cash Flow

We define free cash flow as net cash flows from operating activities less capital expenditures.

Free cash flow, excluding HMRC VAT claims settlement

We define Free cash flow, excluding HMRC VAT claims settlement as free cash flow excluding the Q4 2022 impact of the cash outflow of approximately $733 million (GBP 613 million) related to the settlement of outstanding HMRC VAT claims for periods prior to our UK business model change on March 14, 2022.

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.
