Accounting Policies [Abstract]
Basis of Presentation	NO TE 1: BASIS OF PRESENTATION We refer to Tripadvisor, Inc. and our wholly-owned subsidiaries as “Tripadvisor”, “Tripadvisor group”, the “Company”, “us”, “we” and “our” in these notes to the unaudited condensed consolidated financial statements. Description of Business The Tripadvisor group operates as a family of brands with the purpose of connecting people to experiences worth sharing. Our vision is to be the world’s most trusted source for travel and experiences. The Company operates across three reportable segments: Tripadvisor Core, Viator, and TheFork. We leverage our brands, technology platforms, and capabilities to connect our large, global audience with partners by offering rich content, travel guidance products and services, and two-sided marketplaces for experiences, accommodations, restaurants, and other travel categories. Tripadvisor Core’s purpose is to empower everyone to be a better traveler by serving as the world’s most trusted and essential travel guidance platform. The Tripadvisor brand offers travelers and experience seekers an online global platform for travelers to discover, generate, and share authentic user-generated content, or UGC, in the form of ratings and reviews for destinations, points-of-interest, or POIs, experiences, alternative accommodation rentals, restaurants, and cruises in over 40 countries and over 20 languages across the world. As of December 31, 2022 , Tripadvisor offered more than 1 billion user-generated ratings and reviews on nearly 8 million experiences, accommodations, restaurants, airlines, and cruises. Viator enables travelers to discover and book iconic, unique and memorable experiences from operators around the globe. Viator's online marketplace is comprehensive, connecting travelers to bookable tours, activities and attractions—consisting of over 300,000 experiences from more than 50,000 operators as of December 31, 2022. TheFork provides an online marketplace that enables diners to discover and book online reservations at more than 55,000 restaurants in 12 countries, as of December 31, 2022, across the UK, western and central Europe, and Australia. Basis of Presentation The accompanying unaudited condensed consolidated financial statements present our results of operations, financial position and cash flows on a consolidated basis. The unaudited condensed consolidated financial statements include 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. All inter-company accounts and transactions have been eliminated in consolidation. One of our subsidiaries that operates in China has 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 these 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 activity of these affiliates. Our variable interest entities’ financial results were not material for any of the periods presented. Investments in entities in which we do not have a controlling financial interest are accounted for under the equity method, the fair value option, as available-for-sale securities or at cost adjusted for observable price changes and impairments, as appropriate. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) and include all normal and recurring adjustments that management of the Company considers necessary for a fair presentation of its financial position and operating results. We prepared the unaudited condensed consolidated financial statements following the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, we condensed or omitted certain footnotes or other financial information that are normally required by GAAP for annual financial statements. Additionally, certain prior period amounts have been reclassified for comparability with the current period presentation, none of which were material to the presentation of the accompanying unaudited condensed consolidated financial statements. Our interim unaudited condensed consolidated financial statements are not necessarily indicative of results that may be expected for any other interim period or for the full year. These interim unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2022, previously filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2022 included herein was derived from the audited consolidated financial statements as of that date, but does not include all disclosures including notes required by GAAP. As of September 30, 2023, Liberty Tripadvisor Holdings, Inc. (“LTRIP”) beneficially owned approximately 16.4 million shares of our common stock and approximately 12.8 million shares of our Class B common stock, which constitute 13 % of the outstanding shares of common stock and 100 % of the outstanding shares of Class B common stock. Assuming the conversion of all LTRIP’s shares of Class B common stock into common stock, LTRIP would beneficially own approximately 21 % of the outstanding common stock. Because each share of Class B common stock is entitled to ten votes per share and each share of common stock is entitled to one vote per share , LTRIP may be deemed to beneficially own equity securities representing approximately 57 % of our voting power. We had no related party transactions with LTRIP during the three and nine months ended September 30, 2023 and 2022 , respectively. Risks and Uncertainties Our business was negatively impacted by the risks and uncertainties related to the COVID-19 pandemic. We believe the travel, leisure, hospitality, and restaurant industries, and our financial results, would be adversely and materially affected upon a resurgence of COVID-19 or the emergence of any new pandemic or other health crisis that results in reinstated travel bans and/or other government restrictions and mandates, any of which would likely negatively impact consumer demand, sentiment, and discretionary spending patterns. Additionally, other natural disasters, public health-related events, political instability, geopolitical conflicts, including the evolving events in the Middle East, acts of terrorism, fluctuations in currency values, and changes in global economic conditions, are examples of other events that could have a negative impact on the travel industry, and as a result, our financial results in the future. Accounting Estimates We use estimates and assumptions in the preparation of our unaudited condensed 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 unaudited condensed 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 estimate underlying our unaudited condensed consolidated financial statements is accounting for income taxes. Seasonality Consumer travel expenditures have historically followed a seasonal pattern. Correspondingly, travel partner advertising investments, and therefore our revenue and operating profits, have also historically followed a seasonal pattern. Our financial performance tends to be seasonally highest in the second and third quarters of a given year, which includes the seasonal peak in consumer demand, including traveler accommodation stays, and travel experiences taken, compared to the first and fourth quarters, which represent seasonal low points. In addition, during the first half of the year, experience bookings typically exceed the amount of completed experiences, resulting in higher cash flow related to working capital, while during the second half of the year, particularly in the third quarter, this pattern reverses and cash flows from these transactions are typically negative . Other factors may also impact typical seasonal fluctuations, such as further significant shifts in our business mix, adverse economic conditions, public health-related events, as well as other factors .

Revenue from Contract with Customer [Abstract]
Revenue Recognition	NOTE 3: REVENUE RECOGNITION There have been no material changes to our principal revenue streams, revenue recognition policies, performance obligations, description of and timing of services, or customer payment terms since December 31, 2022, as described under “Note 2: Significant Accounting Policies ” and “Note 3: Revenue Recognition ”, in the notes to consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2022. There was no significant revenue recognized in the three and nine months ended September 30, 2023 and 2022 related to performance obligations satisfied in prior periods. We have applied a practical expedient and do not disclose the value of unsatisfied performance obligations that have an original expected duration of less than one year. The Company expects to complete its performance obligations within one year from the initial transaction date. The value related to our remaining or partially satisfied performance obligations relates to subscription services that are satisfied over time or services that are recognized at a point in time, but not yet achieved. Disaggregation of Revenue We disaggregate revenue from contracts with customers into major products/revenue sources. We have determined that disaggregating revenue into these categories achieves the disclosure objective under GAAP, which is to depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. As noted in “Note 13: Segment Information ,” our business consists of three reportable segments – (1) Tripadvisor Core; (2) Viator; and (3) TheFork. A reconciliation of disaggregated revenue to reportable segment revenue is included below: Three months ended September 30, Nine months ended September 30, 2023 2022 2023 2022 Major products/revenue sources (1) : (in millions) Tripadvisor Core: Tripadvisor-branded hotels $ 181 $ 188 $ 524 $ 510 Tripadvisor-branded display and platform 38 33 110 97 Tripadvisor experiences and dining (2) 55 45 138 101 Other 16 18 41 41 Total Tripadvisor Core 290 284 813 749 Viator 245 174 576 366 TheFork 42 35 115 93 Intersegment eliminations (2) ( 44 ) ( 34 ) ( 106 ) ( 70 ) Total Revenue $ 533 $ 459 $ 1,398 $ 1,138 (1) Our revenue is recognized primarily at a point in time for all reportable segments. (2) Tripadvisor experiences and dining revenue within the Tripadvisor Core segment is shown gross of intersegment (intercompany) revenue, which is eliminated on a consolidated basis. See “Note 13: Segment Information ” for a discussion of intersegment revenue for all periods presented . Deferred Revenue Contract liabilities generally include payments received in advance of performance under the contract and are realized as revenue as the performance obligation to the customer is satisfied, which we present as deferred revenue on our consolidated balance sheet, including amounts that are refundable. As of January 1, 2023, we had $ 44 million recorded as deferred revenue on our unaudited condensed consolidated balance sheet, of which $ 4 million and $ 40 million was recognized as revenue during the three and nine months ended September 30, 2023 , respectively. During the three months ended September 30, 2023, refunds due to cancellations by travelers were no t material, while refunds due to cancellations by travelers during the nine months ended September 30, 2023 were $ 3 million. As of January 1, 2022, we had $ 36 million recorded as deferred revenue on our unaudited condensed consolidated balance sheet, of which $ 5 million and $ 31 million was recognized as revenue during the three and nine months ended September 30, 2022, respectively. During the three months ended September 30, 2022 , refunds due to cancellations by travelers were no t material, while $ 2 million was refunded due to cancellations by travelers during the nine months ended September 30, 2022. The difference between the opening and closing balances of our deferred revenue primarily results from the timing differences between when we receive customer payments and the time in which we satisfy our performance obligations.

Financial Instruments and Fair Value Measurements	NOTE 4: FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS For assets and liabilities required to be reported at fair value, GAAP provides a hierarchy that prioritizes inputs to valuation techniques used to measure fair value into three broad levels: Level 1—Valuations are based on quoted market prices for identical assets and liabilities in active markets. Level 2—Valuations are based on observable inputs other than quoted market prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3—Valuations are based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. Cash, Cash Equivalents and Marketable Securities As of September 30, 2023 and December 31, 2022, we had approximately $ 1.1 billion an d $ 1.0 billion of cash and cash equivalents, respectively, which consisted of available on demand cash deposits and term deposits, as well as money market funds, with maturities of 90 days or less at the date of purchase, in each case, with major global financial institutions. We had no outstanding investments classified as either short-term or long-term marketable securities as of September 30, 2023 and December 31, 2022, and there were no purchases or sales of any marketable securities during and for the three and nine months ended September 30, 2023 and 2022. The following table shows our cash and cash equivalents that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy, as well as their classification on our unaudited condensed consolidated balance sheets as of September 30, 2023 and December 31, 2022 : September 30, 2023 December 31, 2022 Amortized Cost Fair Value (1) Cash and Cash Equivalents Amortized Cost Fair Value (1) Cash and Cash Equivalents (in millions) Cash $ 738 $ 738 $ 738 $ 821 $ 821 $ 821 Level 1: Money market funds 386 386 386 — — — Level 2: Term deposits — — — 200 200 200 Total $ 1,124 $ 1,124 $ 1,124 $ 1,021 $ 1,021 $ 1,021 (1) Unrealized gains and losses related to our cash equivalents were not material . We generally classify cash equivalents and marketable securities, if any, within Level 1 and Level 2 as we value these financial instruments using quoted market prices (Level 1) or alternative pricing sources (Level 2). The valuation technique we use to measure the fair value of money market funds is derived from quoted prices in active markets for identical assets or liabilities. Fair values for Level 2 investments are considered “Level 2” valuations because they are obtained from independent pricing sources for identical or comparable instruments, rather than direct observations of quoted prices in active markets. Our procedures include controls to ensure that appropriate fair values are recorded, including comparing the fair values obtained from our independent pricing services against fair values obtained from another independent source. Derivative Financial Instruments We use forward contracts to reduce the effects of foreign currency exchange rate fluctuations on our cash flows primarily for the Euro versus the U.S. Dollar. For the three and nine months ended September 30, 2023 and 2022 , our forward contracts have not been designated as hedges and generally had maturities of less than 90 days . Our outstanding or unsettled forward contracts are carried at fair value on our unaudited condensed consolidated balance sheet as of both September 30, 2023 and December 31, 2022. We measure the fair value of our outstanding or unsettled derivatives using Level 2 fair value inputs, as we use a pricing model that takes into account the contract terms as well as current foreign currency exchange rates in active markets. We recognize any gain or loss resulting from the change in fair value of o ur foreign currency forward contracts in other income (expense), net on our unaudited condensed consolidated statement of operations. We recorded a net gain of $ 1 million for both the three and nine months ended September 30, 2023 , and a net gain of $ 4 million and $ 6 million for the three and nine months ended September 30, 2022, respectively. The following table shows the net notional principal amounts of our outstanding derivative instruments as of the dates presented : September 30, 2023 December 31, 2022 (in millions) Foreign currency exchange-forward contracts (1) (2) $ 37 $ 18 (1) Derivative contracts address foreign currency exchange fluctuations for the Euro versus the U.S. dollar. These outstanding derivatives are not designated as hedging instruments and have an original maturity period of 90 days or less. (2) The fair value of our outstanding derivatives as of September 30, 2023 was $ 1 million and was reported in prepaid expenses and other current assets on our unaudited condensed consolidated balance sheet. The fair value of our outstanding derivatives as of December 31, 2022 was not material. The notional amount of a forward contract is the contracted amount of foreign currency to be exchanged and is not recorded on the unaudited condensed consolidated balance sheet. Counterparties to our outstanding forward contracts consist of major global financial institutions. We monitor our positions and the credit ratings of the counterparties involved and, by policy limits, the amount of credit exposure to any one party. We do not use derivatives for trading or speculative purposes. We were not entered into any cash flow, fair value or net investment hedges as of September 30, 2023 or December 31, 2022. Other Financial Assets and Liabilities As of September 30, 2023 and December 31, 2022, financial instruments not measured at fair value on a recurring basis, including accounts payable, accrued expenses and other current liabilities, and deferred merchant payables, were carried at cost on our unaudited condensed consolidated balance sheets, which approximates their fair values because of the short-term nature of these items. Accounts receivable and contract assets, as described below, as well as certain other financial assets, are measured at amortized cost and are carried at cost less an allowance for expected credit losses on our unaudited condensed consolidated balance sheet to present the net amount expected to be collected. Accounts Receivable and Contract Assets, net The following table provides information about the opening and closing balances of accounts receivable and contract assets, net of allowance for expected credit losses, from contracts with customers as of the dates presented: September 30, 2023 December 31, 2022 (in millions) Accounts receivable $ 214 $ 173 Contract assets 20 32 Total $ 234 $ 205 Accounts receivable are recognized when the right to consideration becomes unconditional, and are recorded net of an allowance for expected credit losses. We record accounts receivable at the invoiced amount. Our customer invoices are generally due from customers 30 days from the time of invoicing. During the nine months ended September 30, 2023, we recorded $ 5 million of incremental allowance for expected uncollectible accounts, offset by $ 9 million of write-offs for accounts deemed to be uncollectible. The Company's exposure to credit losses may increase if our customers are adversely affected by changes in macroeconomic pressures or uncertainty associated with local or global economic recessions, or other customer-specific factors. Contract assets are rights to consideration in exchange for services that we have transferred to a customer when that right is conditional on something other than the passage of time, such as commission payments that are contingent upon the completion of the service by the principal in the transaction. The difference between the opening and closing balances of our contract assets primarily results from the timing difference between when we satisfy our performance obligations and the time when the principal completes the service in the transaction. Fair Value of Long-Term Debt The following table shows the aggregate principal, carrying value and fair value amounts of the outstanding 2025 Senior Notes and 2026 Senior Notes as of the dates presented, which are classified as long-term debt on our unaudited condensed consolidated balance sheets and considered Level 2 fair value measurements. Refer to “Note 6: Debt ” for additional information on the 2025 Senior Notes and 2026 Senior Notes . September 30, 2023 December 31, 2022 (in millions) 2025 Senior Notes Aggregate principal amount $ 500 $ 500 Carrying value amount (1) 497 495 Fair value amount (2) 499 498 2026 Senior Notes Aggregate principal amount $ 345 $ 345 Carrying value amount (3) 342 341 Fair value amount (2) 293 281 (1) Net of $ 3 million and $ 5 million of unamortized debt issuance costs as of September 30, 2023 and December 31, 2022 , respectively. (2) We estimate the fair value of our outstanding 2025 Senior Notes and 2026 Senior Notes based on recently reported market transactions and/or prices for identical or similar financial instruments obtained from a third-party pricing source. (3) Net of $ 3 million and $ 4 million of unamortized debt issuance costs as of September 30, 2023 and December 31, 2022, respectively . The Company did not have any assets or liabilities measured at fair value on a recurring basis using Level 3 unobservable inputs as of September 30, 2023 and December 31, 2022. Risks and Concentrations Our business is subject to certain financial risks and concentrations, including concentration related to dependence on our relationships with our customers. For the year ended December 31, 2022 , our two most significant travel partners, Expedia Group, Inc. (and its subsidiaries) and Booking Holdings, Inc. (and its subsidiaries), each accounted for 10 % or more of our consolidated revenue and together accounted for approximately 35 % of our consolidated revenue, with nearly all of this revenue concentrated in our Tripadvisor Core segment. Financial instruments, which potentially subject us to concentration of credit risk, generally consist, at any point in time, of cash and cash equivalents, corporate debt securities, forward contracts, capped calls, and accounts receivable. We maintain cash balances with financial institutions that are in excess of Federal Deposit Insurance Corporation insurance limits in the U.S. and similar programs outside the U.S. Our cash and cash equivalents are generally composed of available on demand bank deposits or term deposits with several major global financial institutions, as well as money market funds, primarily denominated in U.S. dollars, and to a lesser extent Euros, British pounds, and Australian dollars. We may invest in highly-rated corporate debt securities, and our investment policy limits the amount of credit exposure to any one issuer, industry group and currency. Our credit risk related to corporate debt securities is also mitigated by the relatively short maturity period required by our investment policy. Forward contracts and capped calls are transacted with major international financial institutions with high credit standings. Forward contracts, which, to date, have typically had maturities of less than 90 days, also mitigate risk. Our overall credit risk related to accounts receivable is mitigated by the relatively short collection period. Assets Measured at Fair Value on a Non-recurring Basis Non-Marketable Investments Equity Securities Accounted for under the Equity Method The Company owns a 40 % equity investment in Chelsea Investment Holding Company PTE Ltd, which is majority owned by Ctrip Investment Holding Ltd, a majority-owned subsidiary of Trip.com Group Limited. The Company accounts for this minority investment under the equity method, given it has the ability to exercise significant influence, but not control, over the investee. The carrying value of this minority investment was $ 30 million and $ 32 million as of September 30, 2023 and December 31, 2022, respectively, and is included in non-marketable investments on our unaudited condensed consolidated balance sheets. During the nine months ended September 30, 2023, we recognized $ 1 million, representing our share of the investee’s net loss in other income (expenses), net within the unaudited condensed consolidated statements of operations, while this amount was not material during the three months ended September 30, 2023. During the three and nine months ended September 30, 2022, we recognized $ 1 million and $ 2 million, respectively, representing our share of the investee’s net loss in other income (expenses), net within the unaudited condensed consolidated statements of operations. The Company evaluates this investment for impairment when factors indicate that a decline in the value of its investment has occurred and the carrying amount of its investment may not be recoverable. An impairment loss, based on the excess of the carrying value over the estimated fair value of the investment based on Level 3 inputs, is recognized in earnings when an impairment is deemed to be other than temporary. During the three and nine months ended September 30, 2023 and 2022 , we did no t record any impairment loss on this equity investment. The Company maintains various commercial agreements with Chelsea Investment Holding Company PTE Ltd. and/or its subsidiaries. Transactions under these agreements are considered related-party transactions, and were not material during the three and nine months ended September 30, 2023 and 2022. Other Long-Term Assets The Company holds collateralized notes (the “Notes Receivable”) issued by a privately held company with a total principal amount of $ 20 million. The Company has classified the Notes Receivable as held-to-maturity, as the Company has concluded it has the positive intent and ability to hold the Notes Receivable until maturity, with 50 % due in June 2025 and the remaining 50 % due in June 2030. As of both September 30, 2023 and December 31, 2022, the carrying value of the Notes Receivable was $ 9 million, net of accumulated allowance for credit losses, and is classified in other long-term assets, net on our unaudited condensed consolidated balance sheets at amortized cost. On a quarterly basis, we perform a qualitative assessment considering impairment indicators to evaluate whether the Notes Receivable are impaired and monitor for changes to our allowance for credit losses. Other non-financial assets, such as property and equipment, goodwill, intangible assets, and operating lease right-of-use assets are adjusted to fair value when an impairment charge is recognized or the underlying investment is sold. Such fair value measurements, if necessary, are based predominately on Level 3 inputs .

Accrued Expenses and Other Current Liabilities	NOTE 5: ACCRUED EXPENSES AND OTHER CURRENT LIABILITIES Accrued expenses and other current liabilities consisted of the following as of the dates presented: September 30, 2023 December 31, 2022 (in millions) Accrued employee salary, bonus, and related benefits $ 62 $ 65 Accrued marketing costs 62 68 Interest payable (1) 8 17 Finance lease liability - current portion 6 6 Operating leases liability - current portion 12 14 Restructuring and other related reorganization cost (2)(3) 14 — Other 66 61 Total $ 230 $ 231 (1) Amount relates primarily to unpaid interest accrued on the 2025 Senior Notes. Refer to “Note 6: Debt ” for further information. (2) During the third quarter of 2023, the Company approved and subsequently initiated a set of actions across its businesses in order to reduce its cost structure, improve operational efficiencies, and realign its workforce with its strategic initiatives. These restructuring and reorganization actions resulted in reduced global headcount. As a result, the Company incurred estimated pre-tax restructuring and other related reorganization costs of $ 18 million during the three months ended September 30, 2023, which consisted primarily of employee severance and related benefits. Potential job position eliminations in each country are subject to local law and consultation requirements, which will extend beyond the fourth quarter of 2023 in certain countries. Therefore, actual costs incurred may differ from estimated costs recorded as of September 30, 2023. (3) We expect that the majority of these costs will be paid during the fourth quarter of 2023 and the first quarter of 2024. The following table summarizes our restructuring and other related reorganization costs for the nine months ended September 30, 2023: Carrying Value (in millions) Accrued liability as of December 31, 2022 $ — Charges 18 Payments ( 3 ) Other ( 1 ) Accrued liability as of September 30, 2023 $ 14

Debt	NOTE 6: DEBT The Company’s outstanding debt consisted of the following as of the dates presented: September 30, 2023 Outstanding Principal Amount Unamortized Debt Issuance Costs Carrying Value (in millions) Long-Term Debt: 2025 Senior Notes $ 500 $ ( 3 ) $ 497 2026 Senior Notes 345 ( 3 ) 342 Total Long-Term Debt $ 845 $ ( 6 ) $ 839 December 31, 2022 Outstanding Principal Amount Unamortized Debt Issuance Costs Carrying Value (in millions) Long-Term Debt: 2025 Senior Notes $ 500 $ ( 5 ) $ 495 2026 Senior Notes 345 ( 4 ) 341 Total Long-Term Debt $ 845 $ ( 9 ) $ 836 Credit Facility We are party to a credit agreement with a group of lenders initially entered into in June 2015 (as amended, the “Credit Agreement”), which, among other things, provid es for a $ 500 million secured revolving credit facility (the “Credit Facility”). On May 8, 2023, the Company declared a “Covenant Changeover Date” (as defined in the Credit Agreement), thereby declaring the Company out of the financial covenant holiday and no longer subject to certain of the restrictive covenants contained in the Credit Agreement. Following that, on June 29, 2023, we amended and restated the Credit Agr eement (the "Restated Credit Agreement") to, among other things, (i) extend the maturity date of the Credit Facility from May 12, 2024 to June 29, 2028 (unless, on any date that is 91 days prior to the final scheduled maturity date in respect of any indebtedness outstanding under certain “specified debt", the aggregate outstanding principal amount of such specified debt is $ 200 million or more then the maturity date will be such business day); (ii) maintain the aggregate amount of revolving commitments available at $ 500 million; (iii) increase the total net leverage ratio from 3.5 to 1.0 to 4.5 to 1.0; and (iv) replace the LIBOR interest rate benchmark with a secured overnight financing rate ("SOFR") interest rate benchmark. The Company may borrow from the Credit Facility in U.S dollars, Euros and Sterling. Borrowings under the Credit Facility generally bear interest, at the Company’s option, at a rate per annum equal to either (i) the Term Benchmark Borrowing rate, or the EURIBO rate for the interest period in effect for such borrowings in Euro; plus an applicable margin ranging from 1.75 % to 2.50 % (“Term Benchmark/RFP Spread”), based on the Company’s total net leverage ratio; (ii) the RFP Borrowing rate, or the Daily Simple Sterling Overnight Interbank Average rate for the interest period in effect for such borrowings in Sterling, plus the Term Benchmark/RFP Spread, based on the Company’s total net leverage ratio ; or (iii) the Alternate Base Rate (“ABR”) Borrowing, which is the greatest of (a) the Prime Rate in effect on such day, (b) the New York Fed Bank Rate in effect on such day plus 1/2 of 1.00% per annum, and (c) the Term Benchmark Borrowing rate, or Adjusted Term SOFR for an interest period of one month as published two US Government Securities Business Days prior to such day (or if such day is not a US Government Securities Business Day, the immediately preceding US Government Securities Business Day) plus 1.00 % per annum ; in addition to an applicable margin ranging from 0.75 % to 1.50 %, based on the Company’s total net leverage ratio. In addition, we are required to pay a quarterly commitment fee, at an applicable rate ranging from 0.25 % to 0.40 %, on the daily unused portion of the Credit Facility for each fiscal quarter and in connection with the issuance of letters of credit. As of September 30, 2023, our unused revolver capacity was subject to a commitment fee of 0.25 % , given the Company’s total net leverage ratio . In addition, the Credit Facility includes $ 15 million of borrowing capacity available for letters of credit and $ 40 million for swing line borrowings on same-day notice. As of September 30, 2023 and December 31, 2022 , the Company had no outstanding borrowings under the Credit Facility and had issued $ 4 million of undrawn standby letters of credit under the Credit Facility. For the three months ended September 30, 2023 and 2022, and the nine months ended September 30, 2023, total interest expense and commitment fees on our Credit Facility was not material, while during the nine months ended September 30, 2022, we recorded total interest expense and commitment fees on the Credit Facility of $ 1 million to interest expense on our unaudited condensed consolidated statement of operations . In connection with the Restated Credit Agreement, we incurred lender fees and other debt financing costs of approximately $ 3 million. These costs were capitalized as deferred financing costs in other long-term assets on our unaudited consolidated balance sheet, while deferred financing costs incurred in previous amendments, which were immediately recognized to interest expense on our unaudited condensed consolidated statements of operations, were not material. As of September 30, 2023, the Company had $ 4 million remaining in deferred financing costs in connection with the Credit Facility. These costs will be amortized over the remaining term of the Credit Facility, using the effective interest rate method, and recorded to interest expense on our unaudited condensed consolidated statement of operations. There is no specific repayment date prior to the maturity date for any borrowings under the Credit Agreement. We may voluntarily repay any outstanding borrowing under the Credit Facility at any time without premium or penalty, other than customary breakage costs with respect to Term Benchmark and RFP interest rate-based loans. Additionally, the Company believes that the likelihood of the lender exercising any subjective acceleration rights, which would permit the lenders to accelerate repayment of any outstanding borrowings, is remote. As such, we intend to classify any future borrowings under this facility as long-term debt. The Credit Agreement contains a number of covenants that, among other things, restrict our ability to incur additional indebtedness, create liens, enter into sale and leaseback transactions, engage in mergers or consolidations, sell or transfer assets, pay dividends and distributions, make investments, loans or advances, prepay certain subordinated indebtedness, make certain acquisitions, engage in certain transactions with affiliates, amend material agreements governing certain subordinated indebtedness, and change our fiscal year. In addition, to secure the obligations under the Credit Agreement, the Company and certain subsidiaries have granted security interests and liens in and on substantially all of their assets as well as pledged shares of certain of the Company’s subsidiaries. The Credit Agreement requires us to maintain a maximum total net leverage ratio and contains certain customary affirmative and negative covenants and events of default, including a change of control. If an event of default occurs, the lenders under the Credit Agreement will be entitled to take various actions, including the acceleration of all amounts due under the Credit Facility. As of September 30, 2023 and December 31, 2022, the Company was in compliance with its existing covenants. 2025 Senior Notes In 2020, the Company issued $ 500 million of outstanding aggregate principal amount of 7.0 % Senior Notes due 2025 (the “2025 Senior Notes”). The 2025 Senior Notes are governed by an indenture dated July 9, 2020 (the “2025 Indenture”), among the Company, the guarantors and the trustee. The 2025 Indenture provides, among other things, that interest is payable on the 2025 Senior Notes semiannually on January 15 and July 15 of each year, and continues until their maturity date of July 15, 2025 . The 2025 Senior Notes are senior unsecured obligations of the Company and are unconditionally guaranteed on a joint and several basis, by certain of the Company’s domestic subsidiaries. The Company has the option to redeem all or a portion of the 2025 Senior Notes at the redemption prices set forth in the 2025 Indenture, plus accrued and unpaid interest, if any. As of September 30, 2023 and December 31, 2022, unpaid interest on the 2025 Senior Notes totaled approximately $ 7 million and $ 16 million, respectively, and was included in accrued expenses and other current liabilities on our unaudited condensed consolidated balance sheets. During each of the three months ended September 30, 2023 and 2022, we recorded interest expense of $ 9 million, and during each of the nine months ended September 30, 2023 and 2022, we recorded interest expense of $ 26 million on our unaudited condensed consolidated statements of operations. The 2025 Indenture contains covenants that, among other things and subject to certain exceptions and qualifications, restrict the ability of the Company and certain of its subsidiaries to incur or guarantee additional indebtedness or issue disqualified stock or certain preferred stock; pay dividends and make other distributions or repurchase stock; make certain investments; create or incur liens; sell assets; create restrictions affecting the ability of restricted subsidiaries to make distributions, loans or advances or transfer assets to the Company or the restricted subsidiaries; enter into certain transactions with the Company’s affiliates; designate restricted subsidiaries as unrestricted subsidiaries; and merge, consolidate or transfer or sell all or substantially all of the Company’s assets. 2026 Senior Notes In 2021, the Company issued $ 345 million in outstanding aggregate principal amount of 0.25 % Convertible Senior Notes due 2026 (the “2026 Senior Notes”). The Company also entered into an Indenture dated March 25, 2021 (the “2026 Indenture”), among the Company, the guarantors party thereto and the trustee. The terms of the 2026 Senior Notes are governed by the 2026 Indenture. The 2026 Senior Notes mature on April 1, 2026 , unless earlier converted, redeemed or repurchased. The 2026 Senior Notes are senior unsecured obligations of the Company and are unconditionally guaranteed on a joint and several basis by certain of the Company’s domestic subsidiaries, with interest payable semiannually in arrears on April 1 and October 1 of each year. During the three and nine months ended September 30, 2023 and 2022, our effective interest rate, including debt issuance costs, was approximately 0.40 % and approximately 0.50 %, respectively, and total interest expense on our 2026 Senior Notes was not material during the three months ended September 30, 2023 and 2022, while this amount was $ 1 million during each of the nine months ended September 30, 2023 and 2022 . As of September 30, 2023 and December 31, 2022, unpaid interest on the 2026 Senior Notes was also not material. The initial conversion rate for the 2026 Senior Notes is 13.5483 shares of common stock per $ 1,000 principal amount of 2026 Senior Notes, which is equivalent to an initial conversion price of approximately $ 73.81 per share of common stock, or approximately 4.7 million shares of common stock, subject to adjustment upon the occurrence of certain specified events as set forth in the 2026 Indenture. Upon conversion, the Company may choose to pay or deliver, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock. The Company accounts for the 2026 Senior Notes as a liability measured at its amortized cost, and no other features of the 2026 Senior Notes are bifurcated and recognized as a derivative. The 2026 Senior Notes are unsecured and do not contain any financial covenants, restrictions on dividends, restrictions on the incurrence of senior debt or other indebtedness, or restrictions on the issuance or repurchase of securities by the Company. Refer to “Note 9: Debt ” in the notes to consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2022, for additional information pertaining to redemption, conversion, and repurchase features or terms regarding the 2025 Senior Notes and the 2026 Senior Notes. Capped Call Transactions In connection with the issuance of the 2026 Senior Notes, the Company entered into privately negotiated capped call transactions (the “Capped Calls”) with certain of the initial purchasers of the 2026 Senior Notes and/or their respective affiliates and/or other financial institutions (the “Option Counterparties”) at a cost of approximately $ 35 million. The Capped Calls are separate transactions entered into by the Company with each of the Option Counterparties, and are not part of the terms of the 2026 Senior Notes and therefore will not affect any noteholder’s rights under the 2026 Senior Notes. Noteholders will not have any rights with respect to the Capped Calls. The Capped Calls cover, subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the 2026 Senior Notes, the number of shares of common stock initially underlying the 2026 Senior Notes, or up to approximately 4.7 million shares of our common stock. The Capped Calls are expected generally to reduce potential dilution to the common stock upon any conversion of 2026 Senior Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of such converted 2026 Senior Notes, as the case may be, with such reduction and/or offset subject to a cap. The strike price of the Capped Calls is $ 73.81 , while the cap price of the Capped Calls will initially be $ 107.36 per share of our common stock, which represents a premium of 100 % over the closing price of our common stock of $ 53.68 per share on March 22, 2021, subject to certain customary adjustments under the terms of the Capped Calls. The Capped Calls are considered indexed to our own stock and are considered equity classified under GAAP, and included as a reduction to additional paid-in-capital within stockholders’ equity on the unaudited condensed consolidated balance sheets as of both September 30, 2023 and December 31, 2022 . The Capped Calls are not accounted for as derivatives and their fair value is not remeasured each reporting period.

Income Taxes	NOTE 8: INCOME TAXES Each interim period is considered an integral part of the annual period; accordingly, we measure our income tax expense using an estimated annual effective tax rate. An enterprise is required, at the end of each interim reporting period, to make its best estimate of the annual effective tax rate for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, as adjusted for discrete taxable events that occur during the interim period. Our income tax provision was $ 37 million and $ 115 million for the three and nine months ended September 30, 2023, respectively, and our income tax provision was $ 37 million and $ 61 million for the three and nine months ended September 30, 2022, respectively. The change in our income tax provision during the nine months ended September 30, 2023, when compared to the same period in 2022, was primarily the result of an Internal Revenue Service ("IRS") audit settlement and related adjustment to our existing transfer pricing income tax reserves for subsequent tax years recorded during the three months ended March 31, 2023. Our effective tax rate differed from the U.S. federal statutory rate of 21 % during the three months ended September 30, 2023 primarily due to a reduction of a deferred tax asset related to stock options awarded in August 2013 to our former CEO, Stephen Kaufer, that expired during the three months ended September 30, 2023. Our effective tax rate differed from the U.S. federal statutory rate of 21 % during the nine months ended September 30, 2023 primarily as a result of the IRS audit settlement, as described above, during the first quarter of 2023. A reconciliation of the provision (benefit) for income taxes to the amounts computed by applying the statutory federal income tax rate to income (loss) before income taxes is as follows for the periods presented: Nine months ended September 30, 2023 2022 (in millions) Income tax expense (benefit) at the federal statutory rate $ 20 $ 17 State income taxes, net of effect of federal tax benefit 7 5 Unrecognized tax benefits and related interest 7 23 Stock-based compensation 21 11 Research tax credit ( 3 ) ( 5 ) Change in valuation allowance 9 8 IRS audit settlement 31 — Transfer pricing reserves adjustment 24 — Other, net ( 1 ) 2 Provision (benefit) for income taxes $ 115 $ 61 Our accounting policy is to recognize accrued interest and penalties related to unrecognized tax benefits and income tax liabilities as part of our income tax expense. As of September 30, 2023 , we had an accrued interest liability of $ 46 million and no penalties have been accrued. We are currently under examination by the IRS for the 2014 through 2016 and 2018 tax years and have various ongoing audits for foreign and state income tax returns. These audits include questions regarding or review of the timing and amount of income and deductions and the allocation of income among various tax jurisdictions. These examinations may lead to proposed or ordinary course adjustments to our taxes. We are no longer subject to tax examinations by tax authorities for years prior to 2014. As of September 30, 2023, no material assessments have resulted, except as noted below regarding our 2009, 2010, and 2011 IRS audit with Expedia, our 2014 through 2016 standalone IRS audit, and our 2012 through 2016 HM Revenue & Customs (“HMRC”) audit. As disclosed in previous filings, including in our Annual Report on Form 10-K for the year ended December 31, 2022, we received Notices of Proposed Adjustments ("NOPA") from the IRS with respect to income tax returns filed by Expedia when Tripadvisor was part of Expedia Group’s consolidated income tax return for the 2009, 2010, and 2011 tax years. The assessment was related to certain transfer pricing arrangements with foreign subsidiaries, for which we had requested competent authority assistance under the Mutual Agreement Procedure (“MAP”) for the 2009 through 2011 tax years. In January 2023, we received a final notice from the IRS regarding a MAP settlement for the 2009 through 2011 tax years, which the Company accepted in February 2023. In the first quarter of 2023, we recorded additional income tax expense as a discrete item, inclusive of interest, of $ 31 million specifically related to this settlement. During the first quarter of 2023, we reviewed the impact of the acceptance of this settlement position against our existing transfer pricing income tax reserves for the subsequent tax years, which resulted in incremental income tax expense, inclusive of estimated interest, of $ 24 million. The total impact of these adjustments resulted in an incremental income tax expense of $ 55 million, which was recognized during the three months ended March 31, 2023. During the three months ended June 30, 2023, we made a U.S. federal tax payment of $ 113 million, inclusive of interest, to Expedia related to this IRS audit settlement, pursuant to the Tax Sharing Agreement with Expedia. During the three months ended September 30, 2023, we received a competent authority refund of $ 49 million, inclusive of interest income, which was previously recorded in income taxes receivable on our unaudited condensed consolidated balance sheet as of June 30, 2023. We anticipate the federal tax benefits, net of remaining state tax payments due, associated with this IRS audit settlement will be substantially settled in the next twelve months, resulting in an estimated net cash inflow of $ 5 million to $ 10 million, which is reflected in income taxes payable on our unaudited condensed consolidated balance sheet as of September 30, 2023. Separately, during August 2020, we received a NOPA from the IRS for the 2014, 2015, and 2016 tax years. These proposed adjustments pertain to certain transfer pricing arrangements with our foreign subsidiaries and would result in additional income tax expense above our existing tax reserves as of September 30, 2023, in an estimated range of $ 55 million to $ 65 million at the close of the audit if the IRS prevails. This estimated range takes into consideration competent authority relief, existing income tax reserves, and transition tax regulations and is exclusive of deferred tax consequences and interest expense, which would also be significant. We disagree with the proposed adjustments, and we intend to defend our position through applicable administrative and, if necessary, judicial remedies. Based on our interpretation of the regulations and available case law, we believe the position we have taken with regard to transfer pricing with our foreign subsidiaries is sustainable. In addition to the risk of additional tax for the years discussed above, if the IRS were to seek transfer pricing adjustments of a similar nature for transactions in subsequent years, we may be subject to significant additional tax liabilities. We have previously requested competent authority assistance under MAP for the tax years 2014 through 2016. We reviewed our transfer pricing reserves as of September 30, 2023 and, based on the facts and circumstances that existed as of the reporting date, consider them to be the Company’s best estimate as of September 30, 2023. As of December 31, 2022, we had recorded $ 204 million of unrecognized tax benefits, inclusive of interest, classified as other long-term liabilities on our unaudited condensed consolidated balance sheet. As a result of the Company's acceptance of MAP with the IRS for the tax years 2009 through 2011, and its impact on other ongoing IRS audits, as described above, during the first quarter of 2023, we reduced this unrecognized tax benefits liability by $ 59 million, reclassifying this balance to income taxes payable. We also increased our income taxes receivable balance by $ 46 million, representing short-term competent authority relief, or payment due from a foreign jurisdiction, which was subsequently received during the third quarter of 2023, as noted above, while reducing our long-term income taxes receivable by $ 45 million, representing our previous estimate of competent authority relief, previously recorded to other long-term assets on our unaudited condensed consolidated balance sheet as of December 31, 2022. In January 2021, we received an issue closure notice from HMRC relating to adjustments for the 2012 through 2016 tax years. These proposed adjustments are related to certain transfer pricing arrangements with our foreign subsidiaries and would result in an increase to our income tax expense in an estimated range of $ 25 million to $ 35 million, exclusive of interest expense, at the close of the audit if HMRC prevails. We disagree with the proposed adjustments, and we intend to defend our position through applicable administrative and, if necessary, judicial remedies. Our policy is to review and update tax reserves as facts and circumstances change. Based on our interpretation of the regulations and available case law, we believe the position the Company has taken with regard to transfer pricing with our foreign subsidiaries is sustainable.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 9: COMMITMENTS AND CONTINGENCIES As of September 30, 2023, there have been no material changes to our commitments and contingencies since December 31, 2022. Refer to “Note 12: Commitments and Contingencies ,” in the notes to our consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2022. Legal Proceedings In the ordinary course of business, we are party to legal, regulatory and administrative matters, including threats thereof, arising out of, or in connection with our operations. These matters may involve claims involving intellectual property rights (including privacy rights and alleged infringement of third-party intellectual property rights), tax matters (including value-added, excise, transient occupancy and accommodation taxes), regulatory compliance (including competition and consumer protection matters), defamation and reputational claims, personal injury claims, labor and employment matters and commercial disputes. Periodically, we review the status of all significant outstanding matters to assess any potential financial exposure. We record the estimated loss in our consolidated statements of operations when (i) it is probable that an asset has been impaired or a liability has been incurred; and (ii) the amount of the loss can be reasonably estimated and is material. We provide disclosures in the notes to the consolidated financial statements for loss contingencies that do not meet both of these conditions if there is a reasonable possibility that a loss may have been incurred that would be material to the consolidated financial statements. We base accruals on the best information available at the time, which can be highly subjective. Although occasional adverse decisions or settlements may occur, we do not believe that the final disposition of any of these matters will have a material adverse effect on our business. However, the final outcome of these matters could vary significantly from our estimates. Finally, there may be claims or actions pending or threatened against us of which we are currently not aware and the ultimate disposition of which could have a material adverse effect on us. All legal fees incurred by the Company related to any regulatory and legal matters are expensed in the period incurred. Income and Non-Income Taxes We are under audit by the IRS and various other domestic and foreign tax authorities with regards to income tax and non-income tax matters. We have reserved for potential adjustments that may result from examinations by, or any negotiated agreements with, these tax authorities. Although we believe our tax estimates are reasonable, the final determination of audits could be materially different from our historical tax provisions and accruals. The results of an audit could have a material effect on our financial position, results of operations, or cash flows in the period for which that determination is made. Refer to “Note 8: Income Taxes ” for further information on potential contingencies surrounding income taxes.

Share-Based Payment Arrangement [Abstract]
Stock Based Awards and Other Equity Instruments	NOTE 10: STOCK BASED AWARDS AND OTHER EQUITY INSTRUMENTS On June 6, 2023, our stockholders approved the TripAdvisor, Inc. 2023 Stock and Annual Incentive Plan (the “2023 Plan”) primarily for the purpose of providing sufficient reserves of shares of our common stock to ensure our ability to continue to provide new hires, employees, and other participants with equity incentives. The 2023 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), and other stock-based awards. As of September 30, 2023 , the total number of shares reserved for future stock-based awards under the 2023 Plan was approximately 19 million shares, calculated as follows: 12 million shares plus the number of shares available for issuance (and not subject to outstanding awards) under the TripAdvisor, Inc. 2018 Stock and Annual Incentive Plan (the “2018 Plan”). All shares of common stock issued to date in respect of the exercise of options, RSUs, or other equity awards have been issued from authorized, but unissued common stock. Stock-Based Compensation Expense The following table presents the amount of stock-based compensation expense and the related income tax benefit included in our unaudited condensed consolidated statements of operations during the periods presented: Three months ended Nine months ended September 30, September 30, 2023 2022 2023 2022 (in millions) (in millions) Total stock-based compensation expense $ 24 $ 22 $ 72 $ 65 Income tax benefit from stock-based compensation ( 5 ) ( 4 ) ( 15 ) ( 14 ) Total stock-based compensation expense, net of tax $ 19 $ 18 $ 57 $ 51 We capitalized $ 2 million and $ 8 million of stock-based compensation expense as website development costs during the three and nine months ended September 30, 2023, respectively, and $ 2 million and $ 7 million during the three and nine months ended September 30, 2022, respectively. Stock-Based Award Activity and Valuation 2023 Stock Option Activity A summary of our stock option activity, consisting of service-based non-qualified stock options, is presented below: Weighted Weighted Average Average Exercise Remaining Aggregate Options Price Per Contractual Intrinsic Outstanding Share Life Value (in thousands) (in years) (in millions) Options outstanding at December 31, 2022 5,462 $ 43.48 Granted 150 20.51 Cancelled or expired (1) ( 1,622 ) 60.21 Options outstanding at September 30, 2023 3,990 $ 35.81 5.4 $ — Exercisable as of September 30, 2023 2,846 $ 40.01 4.1 $ — Vested and expected to vest after September 30, 2023 (2) 3,844 $ 36.14 5.3 $ — (1) Inclusive of 1,100,000 stock options awarded in August 2013 to our former CEO, Stephen Kaufer, that expired during the third quarter of 2023. The expiration of these stock options had no impact to our stock-based compensation expense under GAAP during the third quarter of 2023. (2) The Company accounts for forfeitures as they occur, rather than estimate expected forfeitures as allowed under GAAP and therefore does not include a forfeiture rate in its vested and expected to vest calculation unless necessary for a performance condition award. The weighted-average grant date fair value of stock options issued during the nine months ended September 30, 2023 and 2022, using a Black-Scholes Merton option-pricing model, was $ 10.32 and $ 9.47 , respectively. The total fair value of stock options vested was $ 6 million and $ 15 million for the nine months ended September 30, 2023 and 2022, respectively. 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 September 30, 2023 was $ 16.58 . 2023 RSU Activity A summary of our RSU activity, consisting of service-based vesting terms, is presented below : Weighted Average Grant- Aggregate RSUs Date Fair Intrinsic Outstanding Value Per Share Value (in thousands) (in millions) Unvested RSUs outstanding as of December 31, 2022 8,572 $ 28.41 Granted 6,834 21.51 Vested and released (1) ( 2,971 ) 30.12 Cancelled ( 1,090 ) 26.20 Unvested RSUs outstanding as of September 30, 2023 (2) 11,345 $ 24.02 $ 188 (1) Inclusive of approximate ly 680,000 RSU s withheld due to net share settlement to satisfy required employee tax withholding requirements. Potential shares which had been convertible under RSUs that were withheld under net share settlement remain in the authorized but unissued pool under the 2023 Plan and can be reissued by the Company. Total payments for the employees’ tax obligations to the taxing authorities due to net share settlements are reflected as a financing activity within the unaudited condensed consolidated statements of cash flows. (2) The Company accounts for forfeitures as they occur, rather than estimate expected forfeitures as allowed under GAAP and therefore does not include a forfeiture rate in its vested and expected to vest calculation unless necessary for a performance condition award. RSUs are measured at fair value based on the quoted price of our common stock at the date of grant. We amortize the grant-date fair value of RSUs as stock-based compensation expense over the vesting term, which is typically over a four-year requisite service period 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 total fair value of RSUs vested was $ 89 million and $ 96 million for the nine months ended September 30, 2023 and 2022, respectively. A summary of our performance-based RSUs ("PSUs") and market-based RSUs (“MSUs”) activity is presented below : PSUs (1) MSUs (2) Weighted Weighted Average Average Grant- Aggregate Grant- Aggregate Date Fair Intrinsic Date Fair Intrinsic Outstanding Value Per Share Value Outstanding Value Per Share Value (in thousands) (in millions) (in thousands) (in millions) Unvested and outstanding as of December 31, 2022 — $ — 592 $ 10.00 Granted 546 18.45 34 14.80 Cancelled ( 11 ) 18.45 ( 54 ) 9.26 Unvested and outstanding as of September 30, 2023 535 $ 18.45 $ 9 572 $ 10.35 $ 9 (1) Represents PSUs awarded in February 2023. The PSU awards provide for vesting in two equal annual installments on each of February 15, 2024 and February 15, 2025, based on the extent to which the Company achieves certain financial metrics relative to targets established by the Company’s Compensation Committee of its Board of Directors. The estimated grant-date fair value per PSU was measured based on the quoted price of our common stock at the date of grant, calculated upon the establishment of performance targets, and will be amortized on a straight-line basis over the requisite service period. Based upon actual attainment relative to the target financial metrics, employees have the ability to receive up to 200% of the target number originally granted, or to be issued none at all. Probable outcome for performance-based awards is updated based upon changes in actual and forecasted operating results or expected achievement of performance goals, as applicable, and the impact of modifications, if any. (2) MSUs shall vest three years from grant date, generally with 25% vesting if the weighted-average stock price over a 30-day trading period during the vesting period is equal to or greater than $35.00 but less than $45.00, 50% vesting if equal to or greater than $45.00 but less than $55.00, and 100% vesting if equal to or greater than $55.00, subject to continuous employment with, or performance of services for, the Company . A Monte-Carlo simulation model, which simulated the present value of the potential outcomes of future stock prices was used to calculate the grant-date fair value of our MSU awards. The estimated grant-date fair value of these awards is amortized on a straight-line basis over the requisite service period and is not adjusted based on the actual number of awards that ultimately vest. Income tax benefits associated with the exercise or settlement of all Tripadvisor stock-based awards held by our employees was $ 2 million and $ 8 million during the three and nine months ended September 30, 2023, respectively, and $ 4 million and $ 7 million during the three and nine months ended September 30, 2022, respectively. As of September 30, 2023, total unrecognized compensation cost related to stock-based awards, substantially RSUs, was $ 255 million, which the Company expects to recognize over a weighted-average period of 2.8 years.

Equity [Abstract]
Stockholders' Equity	NOTE 11: STOCKHOLDERS’ EQUITY On November 1, 2019, our Board of Directors authorized the repurchase of an additional $ 100 million in shares of our common stock under our existing share repurchase program, which increased the amount available to the Company under this share repurchase program to $ 250 million. Our Board of Directors authorized and directed management, working with the Executive Committee of our Board of Directors, to affect the share repurchase program in compliance with applicable legal requirements. As of December 31, 2022 , the Company had $ 75 million remaining under this existing share repurchase program to repurchase shares of its common stock. During the three months ended June 30, 2023, we repurchased 4,724,729 shares of our outstanding common stock at an average price of $ 15.85 per share, exclusive of fees and commissions, or $ 75 million in the aggregate, which completed this share repurchase program. On September 7, 2023, our Board of Directors authorized the repurchase of $ 250 million in shares of our common stock under a new share repurchase program. Our Board of Directors authorized and directed management, working with the Executive Committee of our Board of Directors, to affect the share repurchase program in complia nce with applicable legal requirements. The Executive Committee will determine the price, timing, amount and method of such repurchases based on its evaluation of market conditions and other factors, and at prices determined to be attractive and in the best interests of both the Company and its stockholders. This new share repurchase program, which has a term of two years , does not obligate the Company to acquire any particular number of shares and may be modified, suspended or discontinued at any time. During the three months ended September 30, 2023 , the Company has no t repurchased any shares of outstanding common stock under this new share repurchase program. On August 16, 2022, the Inflation Reduction Act was signed into law, and imposed a nondeductible 1 % excise tax on the net value of certain stock repurchases made after December 31, 2022. For the three and nine months ended September 30, 2023, the excise tax on share repurchases was not material. As of September 30, 2023, the Company held 23,569,343 shares of its common stock in treasury with an aggregate cost of $ 797 million.

Earnings Per Share

Earnings Per Share	9 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 12: EARNINGS PER SHARE We compute basic earnings per share ("Basic EPS") by dividing net income (loss) by the weighted average number of common shares outstanding during the period. We compute diluted earnings per share ("Diluted EPS") by dividing net income (loss) by the sum of the weighted average number of common shares outstanding including the dilutive effect of stock-based awards as determined under the treasury stock method and of our 2026 Senior Notes using the if-converted method, as share settlement is presumed, under GAAP. In periods when we recognize a net loss, we exclude the impact of outstanding stock-based awards and the potential share settlement impact related to our 2026 Senior Notes from the Diluted EPS calculation as their inclusion would have an antidilutive effect. Accordingly, for periods in which we report a net loss, such as for the nine months ended September 30, 2023, Diluted EPS is the same as Basic EPS. Additionally, in periods when the 2026 Senior Notes are dilutive, interest expense, net of tax, is added back to net income (loss) (the “numerator”) to calculate Diluted EPS. The Capped Calls are excluded from the calculation of Diluted EPS, as they would be antidilutive. However, upon conversion of the 2026 Senior Notes, unless the market price of our common stock exceeds the cap price, an exercise of the Capped Calls would generally offset any dilution from the 2026 Senior Notes from the conversion price up to the cap price. As of September 30, 2023 and 2022, the market price of a share of our common stock did not exceed the $ 107.36 cap price. Below is a reconciliation of the weighted average number of common shares outstanding used to calculate Diluted EPS for the periods presented : Three months ended September 30, Nine months ended September 30, 2023 2022 2023 2022 (shares in thousands and $ in millions, except per share amounts) Numerator: Net income (loss) (1) $ 27 $ 25 $ ( 22 ) $ 22 Denominator: Weighted average shares used to compute Basic EPS 138,190 140,219 139,841 139,668 Weighted average effect of dilutive securities: Stock-based awards (Note 10) 422 855 — 1,209 2026 Senior Notes (Note 6) 4,674 4,674 — 3,116 Weighted average shares used to compute Diluted EPS 143,286 145,748 139,841 143,993 Basic EPS $ 0.20 $ 0.18 $ ( 0.16 ) $ 0.16 Diluted EPS $ 0.19 $ 0.17 $ ( 0.16 ) $ 0.15 (1) Interest expense, net of taxes, related to the 2026 Senior Notes which was included in the Diluted EPS calculation for the three months ended September 30, 2023 and 2022, and for the nine months ended September 30, 2022, was not material. Potential common shares, consisting of outstanding stock options, RSUs, and those shares issuable under the 2026 Senior Notes, totaling approximately 14.2 million shares and 21.6 million shares for the three and nine months ended September 30, 2023, respectively, and approximately 11.8 million shares and 14.1 million shares for the three and nine months ended September 30, 2022, respectively, have been excluded from the Diluted EPS calculation because their effect would have been antidilutive. In addition, potential common shares from certain performance-based awards of approximately 1.1 million shares for each of the three and nine months ended September 30, 2023, and approximately 0.5 mi llion shares and 0.2 million shares for the three and nine months ended September 30, 2022, respectively, for which all targets required to trigger vesting had not been achieved, were also excluded from the calculation of weighted average shares used to compute Diluted EPS. The earnings per share amounts are the same for our common stock and Class B common stock because the holders of each class are legally entitled to equal per share distributions whether through dividends or in liquidation. In addition, our non-vested RSUs are entitled to dividend equivalents, which are payable to the holder subject to, and only upon vesting of, the underlying awards and are therefore forfeitable. Given such dividend equivalents are forfeitable, we do not consider them to be participating securities and, consequently, they are not subject to the two‑class method of determining earnings per share.

Segment Information

Segment Reporting [Abstract]
Segment Information	NOTE 13: SEGMENT INFORMATION We have three reportable segments: (1) Tripadvisor Core; (2) Viator; and (3) TheFork. Our Tripadvisor Core segment includes the following revenue sources: (1) Tripadvisor-branded hotels – consisting of hotel meta revenue, primarily click-based advertising revenue, and also hotel B2B revenue, which includes primarily subscription-based advertising and hotel sponsored placements revenue; (2) Tripadvisor-branded display and platform revenue – consisting primarily of display-based advertising revenue (also referred to as "media advertising"); (3) Tripadvisor experiences and dining revenue – consisting of intercompany (intersegment) revenue related to affiliate marketing commissions earned primarily from experience bookings, and to a lesser extent, restaurant reservation bookings on Tripadvisor-branded websites and mobile apps, fulfilled by Viator and TheFork, respectively, which are eliminated on a consolidated basis, in addition to external revenue generated from Tripadvisor restaurant service offerings; and (4) Other revenue – consisting of cruises, alternative accommodation rentals, flights, and rental cars revenue. The nature of the services provided and related revenue recognition policies are summarized by reportable segment in “Note 2: Significant Accounting Policies ” and “Note 3: Revenue Recognition ”, in the notes to consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2022. Our operating segments are determined based on how our chief executive officer, who also serves as our chief operating decision maker (“CODM") manages our business, regularly accesses information, and evaluates performance for operating decision-making purposes, including allocation of resources. Adjusted EBITDA is our segment profit measure and a key measure used by our CODM and Board of Directors to understand and evaluate the operating performance of our business and on which internal budgets and forecasts are based and approved. We define Adjusted EBITDA as net income (loss) plus: (1) (provision) benefit for income taxes; (2) other income (expense), net; (3) depreciation and amortization; (4) stock-based compensation and other stock-settled obligations; (5) goodwill, long-lived asset, and intangible assets impairments; (6) legal reserves and settlements; (7) restructuring and other related reorganization costs; and (8) non-recurring expenses and income. Direct costs are included in the applicable operating segments, including certain corporate general and administrative personnel costs, which have been allocated to each segment. We base these allocations on time-spent analyses, headcount, and other allocation methods we believe are reasonable. We do not allocate certain shared expenses to our reportable segments, such as certain information system costs, technical infrastructure costs, and other costs supporting the Tripadvisor platform and operations, that we do not believe are a material driver of individual segment performance, which is consistent with the financial information used by our CODM. We include these expenses in our Tripadvisor Core segment. Our allocation methodology is periodically evaluated and may change. The following tables present our reportable segment information for the three and nine months ended September 30, 2023 and 2022 and include a reconciliation of Adjusted EBITDA to Net income (loss). We record depreciation and amortization, stock-based compensation and other stock-settled obligations, goodwill, long-lived asset and intangible asset impairments, legal reserves and settlements, and other non-recurring expenses and income, net, which are excluded from segment operating performance, in "Corporate & Eliminations". In addition, we do not report total assets, capital expenditures and related depreciation expense by segment as our CODM does not use this information to evaluate operating segment performance. Accordingly, we do not regularly provide such information by segment to our CODM. Our segment disclosure includes intersegment revenues, which consist of affiliate marketing fees for services provided by our Tripadvisor Core segment to both our Viator and TheFork segments. These intersegment transactions are recorded by each segment at amounts that we believe approximate fair value as if the transactions were between third parties and, therefore, impact segment performance.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements present our results of operations, financial position and cash flows on a consolidated basis. The unaudited condensed consolidated financial statements include 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. All inter-company accounts and transactions have been eliminated in consolidation. One of our subsidiaries that operates in China has 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 these 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 activity of these affiliates. Our variable interest entities’ financial results were not material for any of the periods presented. Investments in entities in which we do not have a controlling financial interest are accounted for under the equity method, the fair value option, as available-for-sale securities or at cost adjusted for observable price changes and impairments, as appropriate. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) and include all normal and recurring adjustments that management of the Company considers necessary for a fair presentation of its financial position and operating results. We prepared the unaudited condensed consolidated financial statements following the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, we condensed or omitted certain footnotes or other financial information that are normally required by GAAP for annual financial statements. Additionally, certain prior period amounts have been reclassified for comparability with the current period presentation, none of which were material to the presentation of the accompanying unaudited condensed consolidated financial statements. Our interim unaudited condensed consolidated financial statements are not necessarily indicative of results that may be expected for any other interim period or for the full year. These interim unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2022, previously filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2022 included herein was derived from the audited consolidated financial statements as of that date, but does not include all disclosures including notes required by GAAP. As of September 30, 2023, Liberty Tripadvisor Holdings, Inc. (“LTRIP”) beneficially owned approximately 16.4 million shares of our common stock and approximately 12.8 million shares of our Class B common stock, which constitute 13 % of the outstanding shares of common stock and 100 % of the outstanding shares of Class B common stock. Assuming the conversion of all LTRIP’s shares of Class B common stock into common stock, LTRIP would beneficially own approximately 21 % of the outstanding common stock. Because each share of Class B common stock is entitled to ten votes per share and each share of common stock is entitled to one vote per share , LTRIP may be deemed to beneficially own equity securities representing approximately 57 % of our voting power. We had no related party transactions with LTRIP during the three and nine months ended September 30, 2023 and 2022 , respectively.
Risks and Uncertainties	Risks and Uncertainties Our business was negatively impacted by the risks and uncertainties related to the COVID-19 pandemic. We believe the travel, leisure, hospitality, and restaurant industries, and our financial results, would be adversely and materially affected upon a resurgence of COVID-19 or the emergence of any new pandemic or other health crisis that results in reinstated travel bans and/or other government restrictions and mandates, any of which would likely negatively impact consumer demand, sentiment, and discretionary spending patterns. Additionally, other natural disasters, public health-related events, political instability, geopolitical conflicts, including the evolving events in the Middle East, acts of terrorism, fluctuations in currency values, and changes in global economic conditions, are examples of other events that could have a negative impact on the travel industry, and as a result, our financial results in the future.
Accounting Estimates	Accounting Estimates We use estimates and assumptions in the preparation of our unaudited condensed 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 unaudited condensed 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 estimate underlying our unaudited condensed consolidated financial statements is accounting for income taxes.
Seasonality	Seasonality Consumer travel expenditures have historically followed a seasonal pattern. Correspondingly, travel partner advertising investments, and therefore our revenue and operating profits, have also historically followed a seasonal pattern. Our financial performance tends to be seasonally highest in the second and third quarters of a given year, which includes the seasonal peak in consumer demand, including traveler accommodation stays, and travel experiences taken, compared to the first and fourth quarters, which represent seasonal low points. In addition, during the first half of the year, experience bookings typically exceed the amount of completed experiences, resulting in higher cash flow related to working capital, while during the second half of the year, particularly in the third quarter, this pattern reverses and cash flows from these transactions are typically negative . Other factors may also impact typical seasonal fluctuations, such as further significant shifts in our business mix, adverse economic conditions, public health-related events, as well as other factors .
Significant Accounting Policies	There have been no material changes to our accounting policies since December 31, 2022, as described under “Note 2: Significant Accounting Policies ”, in the notes to consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2022 .

Refer to “Note 6: Debt ” for further information. (2) During the third quarter of 2023, the Company approved and subsequently initiated a set of actions across its businesses in order to reduce its cost structure, improve operational efficiencies, and realign its workforce with its strategic initiatives. These restructuring and reorganization actions resulted in reduced global headcount. As a result, the Company incurred estimated pre-tax restructuring and other related reorganization costs of $ 18 million during the three months ended September 30, 2023, which consisted primarily of employee severance and related benefits. Potential job position eliminations in each country are subject to local law and consultation requirements, which will extend beyond the fourth quarter of 2023 in certain countries. Therefore, actual costs incurred may differ from estimated costs recorded as of September 30, 2023. (3) We expect that the majority of these costs will be paid during the fourth quarter of 2023 and the first quarter of 2024.

The expiration of these stock options had no impact to our stock-based compensation expense under GAAP during the third quarter of 2023.

The PSU awards provide for vesting in two equal annual installments on each of February 15, 2024 and February 15, 2025, based on the extent to which the Company achieves certain financial metrics relative to targets established by the Company’s Compensation Committee of its Board of Directors. The estimated grant-date fair value per PSU was measured based on the quoted price of our common stock at the date of grant, calculated upon the establishment of performance targets, and will be amortized on a straight-line basis over the requisite service period. Based upon actual attainment relative to the target financial metrics, employees have the ability to receive up to 200% of the target number originally granted, or to be issued none at all. Probable outcome for performance-based awards is updated based upon changes in actual and forecasted operating results or expected achievement of performance goals, as applicable, and the impact of modifications, if any. (2) MSUs shall vest three years from grant date, generally with 25% vesting if the weighted-average stock price over a 30-day trading period during the vesting period is equal to or greater than $35.00 but less than $45.00, 50% vesting if equal to or greater than $45.00 but less than $55.00, and 100% vesting if equal to or greater than $55.00, subject to continuous employment with, or performance of services for, the Company . A Monte-Carlo simulation model, which simulated the present value of the potential outcomes of future stock prices was used to calculate the grant-date fair value of our MSU awards. The estimated grant-date fair value of these awards is amortized on a straight-line basis over the requisite service period and is not adjusted based on the actual number of awards that ultimately vest.

[1] Amount relates primarily to unpaid interest accrued on the 2025 Senior Notes. Refer to “Note 6: Debt ” for further information. During the third quarter of 2023, the Company approved and subsequently initiated a set of actions across its businesses in order to reduce its cost structure, improve operational efficiencies, and realign its workforce with its strategic initiatives. These restructuring and reorganization actions resulted in reduced global headcount. As a result, the Company incurred estimated pre-tax restructuring and other related reorganization costs of $ 18 million during the three months ended September 30, 2023, which consisted primarily of employee severance and related benefits. Potential job position eliminations in each country are subject to local law and consultation requirements, which will extend beyond the fourth quarter of 2023 in certain countries. Therefore, actual costs incurred may differ from estimated costs recorded as of September 30, 2023. We expect that the majority of these costs will be paid during the fourth quarter of 2023 and the first quarter of 2024.

[1] MSUs shall vest three years from grant date, generally with 25% vesting if the weighted-average stock price over a 30-day trading period during the vesting period is equal to or greater than $35.00 but less than $45.00, 50% vesting if equal to or greater than $45.00 but less than $55.00, and 100% vesting if equal to or greater than $55.00, subject to continuous employment with, or performance of services for, the Company . A Monte-Carlo simulation model, which simulated the present value of the potential outcomes of future stock prices was used to calculate the grant-date fair value of our MSU awards. The estimated grant-date fair value of these awards is amortized on a straight-line basis over the requisite service period and is not adjusted based on the actual number of awards that ultimately vest. Represents PSUs awarded in February 2023. The PSU awards provide for vesting in two equal annual installments on each of February 15, 2024 and February 15, 2025, based on the extent to which the Company achieves certain financial metrics relative to targets established by the Company’s Compensation Committee of its Board of Directors. The estimated grant-date fair value per PSU was measured based on the quoted price of our common stock at the date of grant, calculated upon the establishment of performance targets, and will be amortized on a straight-line basis over the requisite service period. Based upon actual attainment relative to the target financial metrics, employees have the ability to receive up to 200% of the target number originally granted, or to be issued none at all. Probable outcome for performance-based awards is updated based upon changes in actual and forecasted operating results or expected achievement of performance goals, as applicable, and the impact of modifications, if any.
