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 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

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

Stock-Based Compensation Expense

The following table summarizes total stock-based compensation expense by function (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.

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.

Aggregate Driver and Courier Earnings. Aggregate Driver and Courier Earnings refers to fares (net of Uber service fee, taxes and tolls), tips, Driver incentives and Driver benefits.

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. These are generally included in aggregate Drivers and Couriers earnings.

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. These incentives are generally included in aggregate Drivers and Couriers earnings.

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, and Driver incentives) and Freight Revenue. Gross Bookings do not include tips earned by Drivers. Gross Bookings are an indication of the scale of our current platform, which ultimately impacts revenue.

Monthly Active Platform Consumers (“MAPCs”). We define MAPCs as the number of unique consumers who completed a 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.

Revenue Margin. We define Revenue Margin as revenue as a percentage of Gross Bookings.

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.

Trips. We define Trips as the number of completed consumer 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. We believe that Trips are a useful metric to measure the scale and usage of our platform.

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.

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.

Legal, tax, and regulatory reserve changes and settlements

Legal, tax, and regulatory reserve changes and settlements are primarily related to certain significant legal proceedings or governmental investigations related to worker classification definitions, or tax agencies challenging our non-income tax positions. These matters have limited precedent, cover extended historical periods and are unpredictable in both magnitude and timing, therefore are distinct from normal, recurring legal, tax and regulatory matters and related expenses incurred in our ongoing operating performance.

Limitations of Non-GAAP Financial Measures and Adjusted EBITDA Reconciliation

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;
• 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; and unrealized gain (loss) on debt and equity securities, net; 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.

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) acquisition, financing and divestiture related expenses, (v) restructuring and related charges and (vi) other items not indicative of our ongoing operating performance.
