UNAUDITED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: ORGANIZATION AND BASIS OF PRESENTATION

We refer to TripAdvisor, Inc. and our wholly-owned subsidiaries as “TripAdvisor,” “the Company,” “us,” “we” and “our” in these notes to the consolidated financial statements.

During 2011, Expedia, Inc., or Expedia, announced its plan to separate into two independent public companies in order to better achieve certain strategic objectives of its various businesses. We refer to this transaction as the “Spin-Off.” On December 20, 2011, following the close of trading on the NASDAQ Global Select Market (“NASDAQ”), the Spin-Off was completed, and TripAdvisor began trading as an independent public company on December 21, 2011. Expedia effected the Spin-Off by means of a reclassification of its capital stock that resulted in the holders of Expedia capital stock immediately prior to the time of effectiveness of the reclassification having the right to receive a proportionate amount of TripAdvisor capital stock. A one-for-two reverse stock split of outstanding Expedia capital stock occurred immediately prior to the Spin-Off, with cash paid in lieu of fractional shares. In connection with the Spin-Off, Expedia contributed or transferred all of the subsidiaries and assets relating to Expedia’s TripAdvisor Media Group, which were comprised of the TripAdvisor Holdings, LLC combined financial statements, to TripAdvisor and TripAdvisor or one of its subsidiaries assumed all of the liabilities relating to Expedia’s TripAdvisor Media Group.

Our common stock trades on the NASDAQ under the trading symbol “TRIP.”

Description of Business

TripAdvisor is an online travel company, empowering users to plan and have the perfect trip. TripAdvisor’s travel research platform aggregates reviews and opinions of members about destinations, accommodations (hotels, bed and breakfasts, specialty lodging and vacation rentals), restaurants and activities throughout the world through our flagship TripAdvisor brand. TripAdvisor-branded websites include tripadvisor.com in the United States and localized versions of the website in 29 countries, including in China under the brand daodao.com. Beyond travel-related content, TripAdvisor websites also include links to the websites of our travel advertisers allowing travelers to directly book their travel arrangements. In addition to the flagship TripAdvisor brand, we manage and operate 20 other travel media brands: www.airfarewatchdog.com , www.bookingbuddy.com , www.cruisecritic.com , www.everytrail.com , www.familyvacationcritic.com , www.flipkey.com , www.gateguru.com , www.holidaylettings.co.uk , www.holidaywatchdog.com , www.independenttraveler.com , www.jetsetter.com , www.niumba.com , www.onetime.com , www.seatguru.com , www.smartertravel.com , www.tingo.com , www.travelpod.com , www.virtualtourist.com , www.whereivebeen.com , and www.kuxun.cn , connected by the common goal of providing comprehensive travel planning resources across the travel sector. We derive substantially all of our revenue from advertising, primarily through click-based advertising and display-based advertising sales. In addition, we earn revenue through a combination of subscription-based offerings from our Business Listings and Vacation Rental products, transaction revenue from selling room nights on our transactional sites, and other revenue including licensing our content to third-parties. We have one reportable segment: TripAdvisor. The segment is determined based on how our chief operating decision maker manages our business, makes operating decisions and evaluates operating performance.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared by us in accordance with generally accepted accounting principles, or GAAP, for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in financial statements prepared under generally accepted accounting principles for complete periods have been condensed or omitted pursuant to such regulations. In the opinion of management, all adjustments considered necessary for a fair presentation of our financial position, results of operations and cash flows have been included. All such adjustments are of a normal recurring nature. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2012 in our Annual Report on Form 10-K. The results for interim periods are not necessarily indicative of the results to be expected for the full year. The financial statements and related financial disclosures have been presented on a consolidated basis.

Consolidation

Our consolidated financial statements include the accounts of TripAdvisor, our wholly owned subsidiaries, and entities we control, or in which we have a variable interest and are the primary beneficiary of expected cash profits or losses. We record noncontrolling interest in our consolidated financial statements to recognize the minority ownership interest in our consolidated subsidiaries. Noncontrolling interest in the earnings and losses of consolidated subsidiaries represent the share of net income or loss allocated to members or partners in our consolidated entities. Significant intercompany transactions between the TripAdvisor consolidated entities and accounts have been eliminated.

Certain of our subsidiaries that operate in China have variable interests in affiliated entities in China in order to comply with Chinese laws and regulations, which restrict foreign investment in Internet content provision businesses. Although we do not own the capital stock of some of our Chinese affiliates, we consolidate their results as we are the primary beneficiary of the cash losses or profits of these variable interest affiliates and have the power to direct the activities of these affiliates. Although we currently operate at a loss in the Chinese market our variable interest entities are not material for all periods presented.

Accounting Estimates

We use estimates and assumptions in the preparation of our consolidated financial statements in accordance with GAAP. Our estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our consolidated financial statements. These estimates and assumptions also affect the reported amount of net income or loss during any period. Our actual financial results could differ significantly from these estimates. The significant estimates underlying our consolidated financial statements include revenue recognition; recoverability of long-lived assets, valuation and impairment of marketable securities, intangible assets and goodwill; income taxes; useful lives of property and equipment; purchase accounting and stock-based compensation.

Reclassifications

We have reclassified certain amounts related to our prior period results to conform to our current period presentation.

Seasonality

Expenditures by travel advertisers tend to be seasonal. Traditionally, our strongest quarter has been the third quarter, which is a key travel research period, with the weakest quarter being the fourth quarter. However, adverse economic conditions or continued growth of our international operations with differing holiday peaks may influence the typical trend of our seasonality in the future.

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES

Deferred Merchant Payables

We receive cash from travelers at the time of booking related to our transaction-based businesses and we record these amounts, net of commissions, on our consolidated balance sheets as deferred merchant payables. We pay after the travelers’ use and subsequent billing from the hotel or vacation rental owners. Therefore, we receive cash from the traveler prior to paying the hotel and vacation rental owners, and this operating cycle represents a working capital source of cash to us. As long as our transaction-based businesses grow, we expect that changes in working capital related to these transactions will positively impact operating cash flows. As of June 30, 2013, our deferred merchant payables balance was $31.3 million and the related transactions generated positive operating cashflow of $15.5 million during the six months ended June 30, 2013. A payable balance of $14.5 million was acquired with our business acquisitions during the three months ended June 30, 2013. For additional information on our business acquisitions refer to “Note 6— Acquisitions” below. The deferred merchant payables balance at December 31, 2012 was $1.3 million.

There have been no material changes or other additions to our significant accounting policies since December 31, 2012. For additional information about our critical accounting policies and estimates, refer to “Note 2— Significant Accounting Policies ,” included in our Annual Report on Form 10-K for the year ended December 31, 2012.

Recently Adopted Accounting Pronouncements

Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income

In February 2013, the Financial Accounting Standards Board, or FASB, issued new accounting guidance which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. The new guidance requires that companies present, either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified based on its source and is effective for public companies in interim and annual reporting periods beginning after December 15, 2012. Accordingly, we have adopted these presentation requirements during the first quarter of 2013. The adoption of this new guidance did not have a material impact on our consolidated financial statements or disclosure.

NOTE 3: STOCK BASED AWARDS AND OTHER EQUITY INSTRUMENTS

Stock-based compensation expense relates primarily to expense for restricted stock units (“RSUs”) and stock options. Our outstanding RSUs and stock options generally vest over four years.

For the three and six months ended June 30, 2013, we recognized total stock-based compensation expense of $10.2 million and $23.8 million, respectively. The total income tax benefit related to stock-based compensation expense was $4.0 million and $9.3 million for the three and six months ended June 30, 2013, respectively. For the three and six months ended June 30, 2012, we recognized total stock-based compensation expense of $6.8 million and $11.5 million, respectively. The total income tax benefit related to stock-based compensation expense was $2.5 million and $4.0 million for the three and six months ended June 30, 2012, respectively.

TripAdvisor, Inc. 2011 Stock and Annual Incentive Plan, As Amended

On December 20, 2011, our 2011 Stock and Annual Incentive Plan became effective. At our annual meeting of stockholders held on June 28, 2013 (the “Annual Meeting”), our stockholders approved an amendment to our 2011 Stock and Annual Incentive Plan to increase the aggregate number of shares of common stock authorized for issuance thereunder by 15,000,000 shares. We refer to our 2011 Stock and Annual Incentive Plan, as amended by the amendment as the “2011 Incentive Plan.” A summary of the material terms of the 2011 Incentive Plan can be found in “Proposal 3: Approval of The 2011 Stock and Annual Incentive Plan, as amended” in our Proxy Statement on Schedule 14A for the Annual Meeting. The summary of the material terms of the 2011 Incentive Plan is qualified in its entirety by the full text of the 2011 Incentive Plan and the first amendment thereto, which are included in this Quarterly Report on Form 10-Q as Exhibits 4.2 and 4.1, respectively.

2013 Stock Option Activity

The exercise price for all stock options granted by us to date has been equal to the market price of the underlying shares of common stock at the date of grant. In this regard, when making stock option awards, our practice is to determine the applicable grant date and to specify that the exercise price shall be the closing price of our common stock on the date of grant. Stock options granted during the first six months of 2013 have a term of ten years from the date of grant and generally vest over a four-year service period.

During the six months ended June 30, 2013, we granted 1,561,789 primarily service-based stock options under the 2011 Incentive Plan with a weighted average grant-date fair value per option of $23.15. We will amortize the fair value, net of estimated forfeitures, as stock-based compensation expense over the vesting term of generally four years on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date. We use historical data to estimate pre-vesting option forfeitures and record share-based compensation expense only for those awards that are expected to vest. Changes in estimated forfeitures are recognized through a cumulative catch-up adjustment in the period of change which also impacts the amount of stock compensation expense to be recognized in future periods.

A summary of the status and activity for stock option awards relating to our common stock for the six months ended June 30, 2013, is presented below:

Aggregate intrinsic value represents the difference between the closing stock price of our common stock and the exercise price of outstanding, in-the-money options. Our closing stock price as reported on NASDAQ as of June 28, 2013 was $60.87.

The estimated fair value of the options granted under the 2011 Incentive Plan was calculated using a Black-Scholes Merton option-pricing model (“Black-Scholes model”). The Black-Scholes model incorporates assumptions to value stock-based awards, which includes the risk-free rate of return, expected volatility, expected term and expected dividend yield.

Table of Contents

Our risk-free interest rate is based on the rates currently available on zero-coupon U.S. Treasury issues, in effect at the time of the grant, whose remaining maturity period most closely approximates the stock option’s expected term assumption. We estimated the volatility of our common stock by using an average of historical stock price volatility of publicly traded companies that we consider peers based on daily price observations over a period equivalent to or approximate to the expected term of the stock option grants. The decision to use a weighted average volatility factor of a peer group was based upon the relatively short period of availability of data on our common stock. We estimated our expected term using the simplified method for all stock options as we do not have sufficient historical exercise data on our common stock. Our expected dividend yield is zero, as we have not paid any dividends on our common stock to date.

The fair value of stock option grants under the 2011 Incentive Plan has been estimated at the date of grant using the Black–Scholes model with the following weighted average assumptions for the periods presented below:

2013 RSU Activity

During the six months ended June 30, 2013, we granted 994,293 primarily service-based RSUs under the 2011 Incentive Plan for which the fair value was measured based on the quoted price of our common stock at the date of grant. We will amortize the fair value, net of estimated forfeitures, as stock-based compensation expense over the vesting term of generally four years on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date.

The following table presents a summary of RSU activity on our common stock:

A summary of the unrecognized compensation expense, net of estimated forfeitures, and the weighted average period remaining at June 30, 2013 related to our non-vested stock options and RSU awards is presented below (in thousands, except year information):

All shares of common stock issued in respect of the exercise of options or other equity awards since Spin-Off have been issued from authorized, but unissued common stock.
