First Quarter 2018 Operational and Financial Highlights

1

U.S. Tax Cuts and Jobs Act of 2017

         On December 22, 2017, the U.S. Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”) was enacted into law and the new legislation contains several key tax provisions that affected us, including a one-time mandatory transition tax on accumulated foreign earnings and a reduction of the corporate income tax rate to 21% effective January 1, 2018, among others. We are required to recognize the effect of the tax law changes in the period of enactment, such as determining a transition tax (the “Transition Tax”), remeasuring our U.S. deferred tax assets and liabilities, and reassessing the net realizability of our deferred tax assets and liabilities. In December 2017, the U.S. Securities and Exchange Commission (“SEC”) staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allows us to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. As a result, our provision for income taxes increased by $73 million in Q4 2017, the substantial majority of which was driven by the Transition Tax. During the quarter ended March 31, 2018, we recorded an incremental $5 million tax expense for the Transition Tax, reflecting additional information obtained relating to earnings and profits, foreign tax credits, and state taxes. Since the 2017 Tax Act was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretations are expected over the next several months, we consider the accounting of the Transition Tax and certain other deferred tax items to be provisional due to the forthcoming guidance and our ongoing analysis of final year-end data and tax positions. We expect to complete our analysis within the measurement period in accordance with SAB 118.

Adoption of New Revenue Standard

         Effective January 1, 2018, we adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“ASC 606”), using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under the new revenue guidance, while prior period amounts are not adjusted and continue to be reported in accordance with our previous accounting policies under the historical revenue guidance, or ASC 605, Revenue Recognition (“ASC 605”).  Adoption of this new standard resulted primarily in an increase in total revenue of $4 million and an increase in net income of $3 million for the three months ended March 31, 2018, as compared to our accounting policies under ASC 605. We do not expect the adoption of ASC 606 to have a material impact on our consolidated financial statements on an ongoing basis.

Non-GAAP Financial Measures

To supplement our unaudited condensed consolidated financial statements, which are prepared and presented in accordance with GAAP in our press release and related conference call or webcast, we also report certain non-GAAP financial measures. A “non-GAAP financial measure” refers to a numerical measure of a company’s historical or future financial performance, financial position, or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP in such company’s financial statements. We may use the following non-GAAP measures: Adjusted EBITDA, Adjusted EBITDA margin, non-GAAP net income, non-GAAP net income per diluted share, free cash flow, non-GAAP revenue before effects of foreign exchange, and Adjusted EBITDA before effects of foreign exchange.

The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP and should not be considered measures of TripAdvisor’s liquidity. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to our GAAP financial measures reflect the exclusion of certain items, as defined in our non-GAAP definitions below, which are recurring and will be reflected in our financial results for the foreseeable future. In addition, these measures may be different from non-GAAP financial measures used by other companies, even where similarly titled, limiting their usefulness for comparison purposes and therefore should not be used to compare TripAdvisor’s performance to that of other companies. We endeavor to compensate for the limitation of the non-GAAP financial measures presented by also providing the most directly comparable GAAP measures and descriptions of the reconciling items and adjustments to derive the non-GAAP financial measures.

We believe these non-GAAP financial measures provide investors and analysts with useful supplemental information about the financial performance of our business, enable comparison of financial results between periods where certain items may vary independent of business performance, and allow for greater transparency with respect to key measures used by management to operate and analyze our business over different periods of time.

We define our non-GAAP financial measures as below:

TripAdvisor defines “Adjusted EBITDA” as Net Income plus: (1) provision for income taxes; (2) other income (expense), net; (3) depreciation of property and equipment, including amortization of internal use software and website development; (4) amortization of intangible assets; (5) stock-based compensation and other stock-settled obligations; (6) goodwill, long-lived assets and intangible asset impairments; and (7) other non-recurring expenses and income. These items are excluded from our Adjusted EBITDA measure because these items are noncash in nature, or because the amount is not driven by core operating results and renders comparisons with prior periods less meaningful.

TripAdvisor defines “Adjusted EBITDA margin” as Adjusted EBITDA divided by revenue.

Adjusted EBITDA and Adjusted EBITDA margin are key measures used by our management and board of directors to understand and evaluate the operating performance of our business, as a whole and our individual business segments, and on which internal budgets and forecasts are based and approved. In particular, the exclusion of certain expenses in calculating Adjusted EBITDA can provide a useful measure for period-to-period comparisons of our core business. Accordingly, we believe that Adjusted EBITDA and Adjusted EBITDA margin provide useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and Board of Directors and allows for another useful comparison of our performance with our historical results from prior periods.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results reported in accordance with GAAP. Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, including net income and our other GAAP results.

Some of these limitations are:

TripAdvisor defines “non-GAAP net income” as GAAP net income excluding, net of their related tax effects (which excludes the impact of significant changes resulting from tax legislation such as the 2017 Tax Act): (1) stock-based compensation expense and other stock-settled obligations; (2) amortization of intangible assets; (3) goodwill, intangible assets, and other long-lived asset impairments; and (4) certain gains, losses, and other non-recurring income or expenses that we do not believe are indicative of our ongoing operating results. We believe non-GAAP net income is an operating performance measure which provides investors and analysts with useful supplemental information about the financial performance of our business, as it incorporates our unaudited condensed consolidated statement of operations, taking into account depreciation, which management believes is an ongoing cost of doing business, but excluding the impact of certain expenses, infrequently occurring items and items not directly tied to the core operations of our businesses, and also enables comparison of financial results between periods where certain items may vary independent of business performance.

TripAdvisor defines “non-GAAP net income per diluted share”, or non-GAAP diluted EPS, as non-GAAP net income divided by GAAP diluted shares. We believe non-GAAP diluted EPS is useful to investors because it represents, on a per share basis, our unaudited condensed consolidated statement of operations, taking into account depreciation, which we believe is an ongoing cost of doing business, as well as other items which are not allocated to the operating businesses such as interest expense, interest income, income taxes and foreign exchange gains or losses, but excluding the effects of certain expenses not directly tied to the core operations of our businesses. During the second quarter of 2016, TripAdvisor began calculating non-GAAP net income per diluted share using GAAP diluted shares determined under the treasury stock method. This change did not have a material effect on our previously reported non-GAAP EPS calculations in prior periods.

Non-GAAP net income and non-GAAP diluted EPS have some of the same limitations as Adjusted EBITDA. In addition, non-GAAP net income does not include all items that affect our net income and GAAP diluted EPS for the period. Therefore, we think it is important to evaluate these measures along with our unaudited condensed consolidated statements of operations.

TripAdvisor defines “free cash flow” as net cash provided by operating activities less capital expenditures, which are purchases of property and equipment, including capitalization of internal-use software development costs. We believe this financial measure can provide useful supplemental information to help investors better understand underlying trends in our business, as it represents the operating cash flow that our operating businesses generate, less capital expenditures but before taking into account other cash movements that are not directly tied to the core operations of our businesses, such as financing activities, foreign exchange or certain investing activities. Free cash flow has certain limitations in that it does not represent the total increase or decrease in the cash balance for the period, nor does it represent the residual cash flow for discretionary expenditures. Therefore, it is important to evaluate free cash flow along with the unaudited condensed consolidated statements of cash flows.

TripAdvisor calculates our foreign exchange effect of revenue, or “non-GAAP revenue before effects of foreign exchange” on a constant currency basis by excluding the estimated effects of foreign currency exchange on revenue by translating actual revenue for the current year three months ended using the prior period foreign currency exchange rates. We believe this is a useful measure that facilitates management's internal comparison to our historical performance because it excludes the effects of foreign currency volatility that is not indicative of our core operating results.

TripAdvisor calculates our foreign exchange effect of Adjusted EBITDA, or “Adjusted EBITDA before effects of foreign exchange,” on a constant currency basis, by excluding the estimated effects of foreign currency exchange by translating all amounts included in Adjusted EBITDA for the current year three months ended using the prior period foreign currency exchange rates. We believe this is a useful measure that facilitates management's internal comparison to our historical performance because it excludes the effects of foreign currency volatility that is not indicative of our core operating results.

Pursuant to the requirements of Regulation G, we present reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measure below.
