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. The Company's vision is to be the world’s most trusted source for travel and experiences. The Company operates across three reportable segments: Brand Tripadvisor, 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. Brand Tripadvisor’s purpose is to empower everyone to be a better traveler by serving as the world’s most trusted and essential travel guidance platform. Brand Tripadvisor offers travelers and experience seekers an online global platform for travelers to discover, generate, and share authentic user-generated content (“UGC”) in the form of ratings and reviews for destinations, points-of-interest (“POIs”), experiences, accommodations, restaurants, and cruises in over 40 countries and in more than 20 languages across the world. As of December 31, 2023 , Brand Tripadvisor offered more than 1 billion user-generated ratings and reviews on over 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 350,000 experiences from more than 55,000 operators as of December 31, 2023. TheFork provides an online marketplace that enables diners to discover and book online reservations at approximately 55,000 restaurants in 11 countries, across the U.K. and western and central Europe, as of December 31, 2023. 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 all 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, 2023, previously filed with the SEC (the "2023 Annual Report"). The unaudited condensed consolidated balance sheet as of December 31, 2023 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, 2024, Liberty Tripadvisor Holdings, Inc. (“LTRIP”) beneficially owned approximately 16.4 million shares of our common stock and 12.8 million shares of our Class B common stock, which constitute approximately 13 % of the outstanding shares of common stock and 100 % of the outstanding shares of Class B common stock. Assuming the conversion of all of 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 each of the three and nine months ended September 30, 2024 and 2023 . Risks and Uncertainties Our business was negatively impacted by the risks and uncertainties related to the COVID-19 pandemic and our business 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. Following the lifting of restrictions in connection with the COVID-19 pandemic, travel demand increased. In addition, the U.S. and other countries have seen elevated and fluctuating levels of inflation and decreases in discretionary spending patterns by consumers. If macroeconomic conditions deteriorate, consumer demand and spending may decline, we may not be able to pass on increased costs to our customers and any inability to navigate the macroeconomic environment could harm our business, results of operations and financial condition. Additionally, 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. 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 estimates underlying our unaudited condensed consolidated financial statements is accounting for income taxes. Refer to “Note 8: Income Taxes ” for information regarding our significant income tax estimates. 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 significant shifts in our business mix, adverse economic conditions, public health-related events, as well as other factors .

Accounting Policies [Abstract]
Significant Accounting Policies	NOTE 2: SIGNIFICANT ACCOUNTING POLICIES There have been no material changes to our accounting policies since December 31, 2023, as described under “Note 2: Significant Accounting Policies ”, in the notes to consolidated financial statements in Item 8 of our 2023 Annual Report. New Accounting Pronouncements Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance requiring entities to provide additional information in the income tax rate reconciliation and additional disclosures about income taxes paid. The new accounting guidance requires entities to disclose in their rate reconciliation table additional categories of information about federal, state and foreign income taxes and to provide more details about the reconciling items in some categories if the items meet a quantitative threshold. This guidance is effective for annual periods beginning after December 15, 2024, and should be applied prospectively, but entities have the option to apply it retrospectively for each period presented. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. We are currently considering our timing of adoption and are in the process of evaluating the impact of adopting this newly issued accounting rule on our consolidated financial statements and related disclosures. In November 2023, the FASB issued new accounting guidance which expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM") and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. This guidance is effective for annual periods beginning after December 15, 2023, and interim periods within annual periods beginning after December 15, 2024, with early adoption permitted, including adoption in any interim period. We will adopt this guidance with our Annual Report on Form 10-K for the year ended December 31, 2024. The Company is in the process of evaluating changes which may be required to support our future reportable segment disclosures in order to comply with this new guidance, including evaluation of internal reporting, operational processes, controls, and other areas.

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, 2023, as described under “Note 2: Significant Accounting Policies ” in the notes to consolidated financial statements in Item 8 of our 2023 Annual Report. There was no significant revenue recognized in the three and nine months ended September 30, 2024 and 2023, 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) Brand Tripadvisor; (2) Viator; and (3) TheFork. A reconciliation of disaggregated revenue to segment revenue is included below: Three months ended September 30, Nine months ended September 30, 2024 2023 2024 2023 Major products/revenue sources (1) (in millions) Brand Tripadvisor: Tripadvisor-branded hotels $ 151 $ 181 $ 460 $ 524 Media and advertising 40 38 114 110 Tripadvisor experiences and dining (2) 51 55 135 138 Other 13 16 36 41 Total Brand Tripadvisor 255 290 745 813 Viator 270 245 655 576 TheFork 49 42 133 115 Intersegment eliminations (2) ( 42 ) ( 44 ) ( 109 ) ( 106 ) Total Revenue $ 532 $ 533 $ 1,424 $ 1,398 (1) Our revenue is recognized primarily at a point in time for all reportable segments. (2) Tripadvisor experiences and dining revenue within the Brand Tripadvisor 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, 2024, we had $ 49 million recorded as deferred revenue on our unaudited condensed consolidated balance sheet, of which $ 7 million and $ 45 million was recognized as revenue during the three and nine months ended September 30, 2024, respectively. 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, 2024 and 2023 , refunds due to cancellations by travelers were not material, while refunds due to cancellations by travelers during the nine months ended September 30, 2024 and 2023 were $ 3 million. 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	Sep. 30, 2024
Investments, All Other Investments [Abstract]
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 both September 30, 2024 and December 31, 2023, we had approximately $ 1.1 billion of cash and cash equivalents, which consisted of available on demand bank deposits and 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, 2024 or December 31, 2023, and there were no purchases or sales of any marketable securities during and for the three and nine months ended September 30, 2024 and 2023. 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, 2024 and December 31, 2023: September 30, 2024 December 31, 2023 Amortized Cost Fair Value (1) Cash and Cash Equivalents Amortized Cost Fair Value (1) Cash and Cash Equivalents (in millions) Cash $ 816 $ 816 $ 816 $ 685 $ 685 $ 685 Level 1: Money market funds 296 296 296 382 382 382 Total $ 1,112 $ 1,112 $ 1,112 $ 1,067 $ 1,067 $ 1,067 (1) We did not have any unrealized gains and losses related to our cash equivalents . 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 generally use forward contracts to reduce the effects of foreign currency exchange rate fluctuations on our cash flows for the Euro versus the U.S. Dollar. For the three and nine months ended September 30, 2024 and 2023 , our forward contracts were not 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. We measure the fair value of 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 foreign currency forward contracts in other income (expense), net on our unaudited condensed consolidated statement of operations . We recorded a net loss of $ 1 million for both the three and nine months ended September 30, 2024, and a net gain of $ 1 million for both the three and nine months ended September 30, 2023. The following table shows the notional principal amounts of our outstanding derivative instruments for the periods presented: September 30, 2024 December 31, 2023 (in millions) Foreign currency exchange-forward contracts (1) (2) $ 34 $ 9 (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, 2024 and December 31, 2023 , respectively, 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 did not enter into any cash flow, fair value or net investment hedges as of September 30, 2024 or December 31, 2023. Other Financial Assets and Liabilities As of September 30, 2024 and December 31, 2023, 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, including 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, net The following table provides information about the opening and closing balances of accounts receivable, including contract assets, net of allowance for expected credit losses, from contracts with customers as of the dates presented: September 30, 2024 December 31, 2023 (in millions) Accounts receivable $ 220 $ 177 Contract assets 23 15 Total $ 243 $ 192 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. 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. During the periods ended September 30, 2024 and December 31, 2023, there were no significant changes in contract assets related to business combinations, impairments, cumulative catch-ups or other material adjustments. Fair Value of Long-Term Debt The following table shows the aggregate principal and fair value amount of the 2025 Senior Notes, 2026 Senior Notes, and Term Loan B Facility as of the dates presented, primarily classified as long-term debt on our unaudited condensed consolidated balance sheets and are considered Level 2 fair value measurements. Refer to “Note 6: Debt ” for additional information on the 2025 Senior Notes, 2026 Senior Notes, and Term Loan B Facility.

(2) During the third quarter of 2024, the Company issued the $ 500 million Term Loan B Facility and used these borrowed funds to redeem all $ 500 million aggregate principal amount of the Company's outstanding 2025 Senior Notes. Refer to “Note 6: Debt ” for further information. 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, 2024 and December 31, 2023. 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, 2023 , 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 25 % of our consolidated revenue, with nearly all of this revenue concentrated in our Brand Tripadvisor 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 government 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 $ 29 million and $ 30 million as of September 30, 2024 and December 31, 2023 , respectively, and is included in non-marketable investments on our unaudited condensed consolidated balance sheets. During both the nine months ended September 30, 2024 and 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 no t material during both the three months ended September 30, 2024 and 2023. 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, 2024 and 2023 , 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, 2024 and 2023. 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 June 2028 and the remaining 50 % due June 2030, or the date on which there is a change in control, whichever is earlier. As of both September 30, 2024 and December 31, 2023, 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 predominantly on Level 3 inputs .

Debt	NOTE 6: DEBT The Company’s outstanding debt consisted of the following as of the dates presented: September 30, 2024 December 31, 2023 (in millions) Short-term debt: Term Loan B Facility $ 5 $ — Total short-term debt $ 5 $ — Long-term debt: Term Loan B Facility due 2031 $ 495 $ — 0.25 % Convertible 2026 Senior Notes due 2026 345 345 7.00 % 2025 Senior Notes due 2025 — 500 Unamortized Debt Issuance Costs ( 8 ) ( 6 ) Total long-term debt $ 832 $ 839 Credit Agreement We are party to a credit agreement with a group of lenders initially entered into in June 2015 and, amended and restated in June 2023 (the “Credit Agreement”), which, among other things, provides for a $ 500 million secured revolving credit facility (the “Credit Facility”). The Credit Facility has a maturity date of 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). On July 8, 2024, the Company entered into the First Amendment to its Credit Agreement (the “Amended Credit Agreement”), wh ich implements the Term Loan B Facility (discussed below); and among other things: • Does not change the aggregate amount of revolving commitments available at $ 500 million related to our Credit Facility; • Makes certain adjustments to the definition of “Consolidated EBITDA”; • Increases the Available Amount by the portion of excess cash flow and asset sale, casualty and condemnation mandatory prepayments declined by lenders under the Term Loan B Facility, which may be used to make restricted payments and investments; • Adds a separate dollar basket not to exceed the greater of $ 195 million and 50 % of Consolidated EBITDA for capital leases and purchase money debt; • Adds a separate “ratio debt” basket for additional indebtedness up to 3.5 times pro forma Total Net Leverage Ratio , subject to certain customary limitations; and • Adds customary extension and modification and refinancing facility provisions. The Amended Credit Agreement includes certain customary restrictions on the ability of the Company and its subsidiaries to, among other things, incur additional indebtedness, grant additional liens, and make investments, acquisitions, dispositions, distributions, and other payments, with certain exceptions as more specifically described in the Amended Credit Agreement. The Amended Credit Agreement contains customary events of default and modifies the cross-default provision so that the Term Loan B Facility includes a customary cross-acceleration event of default with the Credit Facility under the Amended Credit Agreement. If an event of default occurs and is continuing, then, among other things, the lenders under the Credit Facility and/or the Term Loan B Facility, as applicable, may declare any outstanding Credit Facility and/or Term Loan B Facility obligations, as applicable, under the Amended Credit Agreement to be immediately due and payable and exercise their rights and remedies against the collateral. The obligations under the Amended Credit Agreement are secured by substantially all assets, whether personal, tangible or intangible, of the Company and the Subsidiary Loan Parties as granted under the Security Documents. Any term not otherwise defined herein shall have the meaning ascribed to it in the Amended Credit Agreement. Credit Facility As of September 30, 2024 and December 31, 2023 , we had no outstanding borrowings under the Credit Facility. The Credit Facility also 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, 2024 and December 31, 2023, we had issued $ 3 million and $ 4 million, respectively, of undrawn standby letters of credit under the Credit Facility. For the three months ended September 30, 2024 and 2023, 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, 2024, 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 . The Amended Credit Agreement, among other things, requires us to maintain a maximum total net leverage ratio of 4.5 to 1.0 solely in respect to the Credit Facility and contains certain customary affirmative and negative covenants and events of default, including a change of control . In connection with the Amended Credit Agreement, we incurred lender fees and other debt financing costs of $ 1 million under the Credit Facility. These costs were capitalized as deferred financing costs in other long-term assets on our unaudited consolidated balance sheet as of September 30, 2024. As of September 30, 2024, 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. Term Loan B Facility On July 8, 2024, under the Amended Credit Agreement, the Company issued a $ 500 million Term Loan B Facility maturing July 8, 2031, with an interest rate based on secured overnight financing rate ("SOFR") plus 2.75 %. On July 15, 2024, the Company used these borrowed funds to fully redeem its outstanding $ 500 million, 2025 Senior Notes . As of September 30, 2024, the interest rate on the Term Loan B Facility was 7.60 % and the weighted-average interest rate on the Term Loan B Facility was 8.06 % for the three months ended September 30, 2024. The Term Loan B Facility was offered at 99.75 % of par and is required to be paid down at 1.00 % of the aggregate principal amount per year, repayable in quarterly installments on the last day of each calendar quarter, commencing December 31, 2024, equal to 0.25 % of the original principal amount with the balance due on the maturity date. The Term Loan B Facility has no financial covenants. In connection with the issuance of the Term Loan B Facility, we incurred $ 7 million of debt issuance costs, comprised of the initial purchasers’ discount, lender fees, and other debt financing costs. These debt issuance costs will be amortized over the remaining term of the Term Loan B Facility, using the effective interest rate method, and recorded to interest expense on our unaudited condensed consolidated statement of operations. As of September 30, 2024, unpaid interest on the Term Loan B Facility was not material and $ 10 million was recorded as interest expense on our unaudited condensed consolidated statements of operations during both the three and nine months ended September 30, 2024. 2025 Senior Notes On July 15, 2024 , as noted above, the Company redeemed all $ 500 million aggregate principal amount of the Company’s outstanding 2025 Senior Notes, in addition to the settlement of accrued and unpaid interest . As a result, we recognized a loss on extinguishment of debt of $ 2 million, which primarily consisted of a non-cash write-off of unamortized debt issuance costs, and is included in Other income (expense), net on our unaudited condensed consolidated statements of operations during both the three and nine months ended September 30, 2024. As of December 31, 2023, unpaid interest of $ 16 million related to the 2025 Senior Notes, was included in accrued expenses and other current liabilities on our unaudited condensed consolidated balance sheet. During the three and nine months ended September 30, 2024, we recorded $ 1 million and $ 19 million of interest expense, respectively, while during the three and nine months ended September 30, 2023, we recorded $ 9 million and $ 26 million of interest expense, respectively, on our unaudited condensed consolidated statements of operations. 2026 Senior Notes During the three and nine months ended September 30, 2024 and 2023, our effective interest rate, including debt issuance costs, was approximately 0.35 % and 0.40 % , respectively, and total interest expense incurred from the 2026 Senior Notes was not material during the three months ended September 30, 2024 and 2023, while this amount was $ 1 million during both the nine months ended September 30, 2024 and 2023 . As of September 30, 2024 and December 31, 2023, unpaid interest on the 2026 Senior Notes was not material. 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 at a cost of approximately $ 35 million. The Capped Calls are considered indexed to our own stock and are considered equity classified under GAAP, and therefore included as a reduction to additional paid-in-capital within stockholders’ equity on the unaudited condensed consolidated balance sheets as of both September 30, 2024 and December 31, 2023. The Capped Calls are not accounted for as derivatives and their fair value is not remeasured each reporting period. Refer to “Note 8: Debt ” in the notes to consolidated financial statements in Item 8 of our 2023 Annual Report, for additional information pertaining to redemption, conversion, repurchase features, and other terms regarding the Credit Facility, 2025 Senior Notes, 2026 Senior Notes and Capped Calls.

Income Tax Disclosure [Abstract]
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 $ 27 million and $ 84 million for the three and nine months ended September 30, 2024, respectively, and our income tax provision was $ 37 million and $ 115 million for the three and nine months ended September 30, 2023, respectively. The change in our income tax provision during the nine months ended September 30, 2024, when compared to the same period in 2023, was primarily the result of an Internal Revenue Service ("IRS") audit settlement for the 2014 through 2016 tax years, and an adjustment to our existing transfer pricing income tax reserves for subsequent tax years recorded during the three months ended March 31, 2024, as discussed below. Our effective tax rate for the three months ended September 30, 2024 differs from the U.S. federal statutory rate of 21 %, primarily due to unfavorable stock-based compensation tax effects. Our effective tax rate for the nine months ended September 30, 2024 differs from the U.S. federal statutory rate of 21 %, primarily due to the result of an IRS audit settlement as noted above. 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, 2024 2023 (in millions) Income tax expense (benefit) at the federal statutory rate $ 18 $ 20 State income taxes, net of effect of federal tax benefit 7 7 Unrecognized tax benefits and related interest 4 7 Stock-based compensation 13 21 Research tax credit ( 6 ) ( 3 ) Change in valuation allowance — 9 IRS audit settlement 41 31 Transfer pricing reserves adjustment ( 4 ) 24 Other, net 11 ( 1 ) Provision (benefit) for income taxes $ 84 $ 115 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, 2024 , we had an accrued interest liability of $ 21 million, which was included in unrecognized tax benefits in other long-term liabilities on our unaudited condensed consolidated balance sheet, and no penalties were 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. As of September 30, 2024, no material assessments have resulted, except as noted below regarding our 2014 through 2016 standalone IRS audit, and our 2012 through 2016 HM Revenue & Customs (“HMRC”) audit. As disclosed in our 2023 Annual Report, we received Notices of Proposed Adjustments ("NOPA") from the IRS for the 2014 through 2016 tax years relating to certain transfer pricing arrangements with our foreign subsidiaries. In response, we requested competent authority assistance under the Mutual Agreement Procedure (“MAP”) for the 2014 through 2016 tax years. In January 2024, we received notification of a MAP resolution agreement for the 2014 through 2016 tax years, which we accepted in February 2024. During the three and nine months ended September 30, 2024, we recorded an income tax benefit of $ 4 million and an income tax expense of $ 41 million, respectively, as discrete items, inclusive of interest, related to this settlement on our unaudited condensed consolidated statement of operations. Separately, we reviewed the impact of the acceptance of this settlement position against our existing transfer pricing income tax reserves for the subsequent open tax years during the first quarter of 2024, which resulted in an income tax benefit, inclusive of estimated interest, of $ 4 million. During the three months ended June 30, 2024, we made a payment to the IRS of $ 141 million, inclusive of estimated interest, and during the three months ended September 30, 2024, we made various state tax payments of $ 18 million, inclusive of estimated interest, related to this audit settlement. We anticipate a competent authority refund from a foreign jurisdiction and certain federal tax benefits, net of state tax payments due, associated with this IRS audit settlement which will be substantially settled in the next twelve months, resulting in an estimated net cash inflow of $ 50 million to $ 60 million, inclusive of related interest. The anticipated competent authority refund is reflected in the current income taxes receivable balance of $ 46 million, as well as a lesser amount consisting of anticipated federal tax benefits, partially offset by anticipated state tax payments on our unaudited condensed consolidated balance sheet as of September 30, 2024. As of December 31, 2023, we had recorded $ 153 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 our acceptance of MAP with the IRS for the 2014 through 2016 tax years, and its impact on other ongoing IRS audits, as described above, we reduced this unrecognized tax benefits liability by $ 79 million during the three months ended March 31, 2024 by reclassifying this balance to current income taxes payable on our unaudited condensed consolidated balance sheet, representing a short-term payment obligation to the IRS, which was subsequently paid during the three months ended June 30, 2024, as noted above. In addition, as disclosed in our 2023 Annual Report, we received a NOPA from the IRS for the 2009 through 2011 tax years relating to certain transfer pricing arrangements with our foreign subsidiaries. In response, we also requested competent authority assistance under MAP for the 2009 through 2011 tax years. In January 2023, we received a final notice from the IRS regarding a MAP resolution agreement 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 on our unaudited condensed consolidated statement of operations. 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 on our unaudited condensed consolidated statement of operations of $ 55 million for 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, related to this IRS audit settlement. In January 2021, we received from HMRC an issue closure notice 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 worldwide 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.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 9: COMMITMENTS AND CONTINGENCIES As of September 30, 2024, there have been no material changes to our commitments and contingencies since December 31, 2023, except as discussed below. Refer to “Note 12: Commitments and Contingencies ,” in the notes to our consolidated financial statements in Item 8 of our 2023 Annual Report. 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, but not limited to, 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, consumer protection matters and data privacy or cybersecurity matters), contractual claims (including related to our material agreements or other contracts), 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, except for certain known income tax matters discussed in “Note 8: Income Taxes .” 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. We are under audit by the IRS and various other domestic and foreign tax authorities with regards to income tax matters. We have reserved for potential losses 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 pertaining to current income tax audits. As of September 30, 2024, we have an accrual in the amount of $ 10 million in accrued expenses and other current liabilities in our unaudited condensed consolidated balance sheet, as an estimated potential settlement of a regulatory related matter within our alternative accommodation rentals offering. This amount was accrued during the three months ended March 31, 2024, and is included in general and administrative expenses in our unaudited condensed consolidated statements of operations for the nine months ended September 30, 2024. This accrual is based on our best estimate of probable loss; the ultimate resolution of this contingency may be greater or less than the liability recorded.

Stock Based Awards and Other Equity Instruments	NOTE 10: STOCK BASED AWARDS AND OTHER EQUITY INSTRUMENTS 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, 2024 2023 2024 2023 (in millions) (in millions) Total stock-based compensation expense $ 31 $ 24 $ 92 $ 72 Income tax benefit from stock-based compensation ( 6 ) ( 5 ) ( 18 ) ( 15 ) Total stock-based compensation expense, net of tax $ 25 $ 19 $ 74 $ 57 We capitalized $ 4 million and $ 10 million of stock-based compensation expense as website development costs during the three and nine months ended September 30, 2024, respectively, and $ 2 million and $ 8 million during the three and nine months ended September 30, 2023, respectively. Stock-Based Award Activity and Valuation 2024 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, 2023 3,927 $ 35.56 Granted 45 24.96 Exercised (1) ( 80 ) 24.36 Canceled or expired ( 1,131 ) 35.76 Options outstanding at September 30, 2024 2,761 $ 35.63 4.5 $ — Exercisable as of September 30, 2024 2,193 $ 39.12 3.7 $ — Vested and expected to vest after September 30, 2024 (2) 2,761 $ 35.63 4.5 $ — (1) Inclusive of approximately 67,000 stock options withheld due to net share settlement to satisfy required employee tax withholding requirements. Potential shares which had been convertible under stock options that were withheld under net share settlement remain in the authorized but unissued pool under the Tripadvisor, Inc. 2023 Stock and Annual Incentive Plan (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 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 our vested and expected to vest calculation unless necessary for a performance condition award. Our stock options generally have a term of ten years from the date of grant and typically vest equally over a four-year requisite service period. We amortize the grant-date fair value of our stock option grants as stock-based compensation expense over the vesting term 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 weighted-average grant date fair value of stock options issued during the nine months ended September 30, 2024 and 2023, using a Black-Scholes Merton option-pricing model, was $ 13.37 and $ 10.32 , respectively. The total fair value of stock options vested was $ 6 million for both the nine months ended September 30, 2024 and 2023. 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, 2024 was $ 14.49 . The total intrinsic value of stock options exercised was no t material for the nine months ended September 30, 2024 and 2023. 2024 Restricted Stock Units ("RSUs") Activity A summary of our RSUs 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, 2023 11,520 $ 23.06 Granted 5,677 25.80 Vested and released (1) ( 3,684 ) 24.17 Canceled ( 1,029 ) 24.35 Unvested RSUs outstanding as of September 30, 2024 (2) 12,484 $ 23.87 $ 181 (1) Inclusive of approximate ly 797,000 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 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 our 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 for both the nine months ended September 30, 2024 and 2023. 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, 2023 519 $ 18.45 572 $ 10.35 Granted 602 27.31 — — Canceled ( 149 ) 22.40 ( 81 ) 9.26 Unvested and outstanding as of September 30, 2024 972 $ 23.39 $ 14 491 $ 10.53 $ 7 (1) Represents PSUs awarded primarily in February 2023 and March 2024. The February 2023 PSU awards provide for vesting in two equal annual installments on each of December 31, 2024 and December 31, 2025, if and to the extent the Company achieves pre-determined revenue and Adjusted EBITDA metrics (each weighted 50%) established by the Compensation Committee and Section 16 Committee of its Board of Directors (jointly, the "Compensation Committees"). The March 2024 PSU awards provide for vesting in two equal annual installments on each of December 31, 2025 and December 31, 2026, if and to the extent the Company achieves pre-determined revenue and Adjusted EBITDA metrics (each weighted 50%) established by the Compensation Committees. The estimated grant-date fair values per PSU were 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. Total current income tax benefits associated with the exercise or settlement of Tripadvisor stock-based awards held by our employees was $ 2 million and $ 9 million during the three and nine months ended September 30, 2024, respectively, and $ 2 million and $ 8 million during the three and nine months ended September 30, 2023, respectively. As of September 30, 2024, total unrecognized compensation cost related to stock-based awards, substantially RSUs, was $ 275 million, which the Company expects to recognize over a weighted-average period of 2.7 years.

Stockholders' Equity

Stockholders' Equity	Sep. 30, 2024
Equity [Abstract]
Stockholders' Equity	NOTE 11: STOCKHOLDERS’ EQUITY On September 7, 2023, our Board of Directors authorized the repurchase of $ 250 million in shares of our common stock under a 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 compliance 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 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, 2024 and 2023, the Company did no t repurchase any shares of outstanding common stock under this share repurchase program. During the nine months ended September 30, 2024, we repurchased 1,366,385 shares of our outstanding common stock at an average price of $ 18.28 per share, exclusive of fees and commissions, or $ 25 million in the aggregate. As of September 30, 2024, the Company had $ 200 million remaining available to repurchase shares of its common stock under this share repurchase program. During the nine months ended September 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 a previous share repurchase program. For the three and nine months ended September 30, 2024 and 2023, any excise tax on share repurchases was not material.

Earnings Per Share

Earnings Per Share	9 Months Ended
Earnings Per Share	Sep. 30, 2024
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 the 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 the 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 since dilutive common equivalent shares are not assumed to have been issued if their effect is antidilutive. 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, 2024 and 2023 , 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 shares of common stock outstanding used in calculating Diluted EPS for the periods presented: Three months ended September 30, Nine months ended September 30, 2024 2023 2024 2023 (shares in thousands and $ in millions, except per share amounts) Numerator: Net income (loss) used to compute Basic EPS $ 39 $ 27 $ 4 $ ( 22 ) Interest expense on 2026 Senior Notes, net of tax (1) — — 1 — Net income (loss) used to compute Diluted EPS $ 39 $ 27 $ 5 $ ( 22 ) Denominator: Weighted average shares used to compute Basic EPS 138,915 138,190 138,862 139,841 Weighted average effect of dilutive securities: Stock-based awards (Note 10) 604 422 1,435 — 2026 Senior Notes (Note 6) 4,674 4,674 4,674 — Weighted average shares used to compute Diluted EPS 144,193 143,286 144,971 139,841 Basic EPS $ 0.28 $ 0.20 $ 0.03 $ ( 0.16 ) Diluted EPS $ 0.27 $ 0.19 $ 0.03 $ ( 0.16 ) (1) Interest expense, net of tax, related to the 2026 Senior Notes which was included in the Diluted EPS calculation for both the three months ended September 30, 2024 and 2023 was not material. Potential common shares, consisting of outstanding stock options, RSUs, and those issuable under the 2026 Senior Notes, totaling approximately 13.3 million shares and 12.3 million shares for the three and nine months ended September 30, 2024, respectively, and approximately 14.2 million shares and 21.6 million shares for the three and nine months ended September 30, 2023, 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 1.5 million shares for both the three and nine months ended September 30, 2024, respectively, and approximately 1.1 million shares for both the three and nine months ended September 30, 2023, 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 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 Information	Sep. 30, 2024
Segment Reporting [Abstract]
Segment Information	NOTE 13: SEGMENT INFORMATION We have three reportable segments: (1) Brand Tripadvisor; (2) Viator; and (3) TheFork. Our Brand Tripadvisor 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) Media and advertising 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 3: Revenue Recognition. ” 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, including indirect tax reserves related to audit settlements and the impact of one-time changes resulting from enacted tax legislation; (7) restructuring and other related reorganization costs (benefit); 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 Brand Tripadvisor 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, 2024 and 2023 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 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 Brand Tripadvisor 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. However, the revenue and corresponding expense are eliminated in consolidation. The elimination of such intersegment transactions is included within the “Corporate & Eliminations” column in the tables below .

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 all 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, 2023, previously filed with the SEC (the "2023 Annual Report"). The unaudited condensed consolidated balance sheet as of December 31, 2023 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, 2024, Liberty Tripadvisor Holdings, Inc. (“LTRIP”) beneficially owned approximately 16.4 million shares of our common stock and 12.8 million shares of our Class B common stock, which constitute approximately 13 % of the outstanding shares of common stock and 100 % of the outstanding shares of Class B common stock. Assuming the conversion of all of 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 each of the three and nine months ended September 30, 2024 and 2023 .
Risks and Uncertainties	Risks and Uncertainties Our business was negatively impacted by the risks and uncertainties related to the COVID-19 pandemic and our business 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. Following the lifting of restrictions in connection with the COVID-19 pandemic, travel demand increased. In addition, the U.S. and other countries have seen elevated and fluctuating levels of inflation and decreases in discretionary spending patterns by consumers. If macroeconomic conditions deteriorate, consumer demand and spending may decline, we may not be able to pass on increased costs to our customers and any inability to navigate the macroeconomic environment could harm our business, results of operations and financial condition. Additionally, 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.
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 estimates underlying our unaudited condensed consolidated financial statements is accounting for income taxes. Refer to “Note 8: Income Taxes ” for information regarding our significant income tax estimates.
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 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, 2023, as described under “Note 2: Significant Accounting Policies ”, in the notes to consolidated financial statements in Item 8 of our 2023 Annual Report.
New Accounting Pronouncements Not Yet Adopted	New Accounting Pronouncements Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance requiring entities to provide additional information in the income tax rate reconciliation and additional disclosures about income taxes paid. The new accounting guidance requires entities to disclose in their rate reconciliation table additional categories of information about federal, state and foreign income taxes and to provide more details about the reconciling items in some categories if the items meet a quantitative threshold. This guidance is effective for annual periods beginning after December 15, 2024, and should be applied prospectively, but entities have the option to apply it retrospectively for each period presented. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. We are currently considering our timing of adoption and are in the process of evaluating the impact of adopting this newly issued accounting rule on our consolidated financial statements and related disclosures. In November 2023, the FASB issued new accounting guidance which expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM") and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. This guidance is effective for annual periods beginning after December 15, 2023, and interim periods within annual periods beginning after December 15, 2024, with early adoption permitted, including adoption in any interim period. We will adopt this guidance with our Annual Report on Form 10-K for the year ended December 31, 2024. The Company is in the process of evaluating changes which may be required to support our future reportable segment disclosures in order to comply with this new guidance, including evaluation of internal reporting, operational processes, controls, and other areas.

Total payments for the employees’ tax obligations to the taxing authorities due to net share settlements are reflected as a financing activity within the consolidated statements of cash flows.

The February 2023 PSU awards provide for vesting in two equal annual installments on each of December 31, 2024 and December 31, 2025, if and to the extent the Company achieves pre-determined revenue and Adjusted EBITDA metrics (each weighted 50%) established by the Compensation Committee and Section 16 Committee of its Board of Directors (jointly, the "Compensation Committees"). The March 2024 PSU awards provide for vesting in two equal annual installments on each of December 31, 2025 and December 31, 2026, if and to the extent the Company achieves pre-determined revenue and Adjusted EBITDA metrics (each weighted 50%) established by the Compensation Committees. The estimated grant-date fair values per PSU were 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.

Potential shares which had been convertible under stock options that were withheld under net share settlement remain in the authorized but unissued pool under the Tripadvisor, Inc. 2023 Stock and Annual Incentive Plan (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 consolidated statements of cash flows. 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 our vested and expected to vest calculation unless necessary for a performance condition award.

[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 primarily in February 2023 and March 2024. The February 2023 PSU awards provide for vesting in two equal annual installments on each of December 31, 2024 and December 31, 2025, if and to the extent the Company achieves pre-determined revenue and Adjusted EBITDA metrics (each weighted 50%) established by the Compensation Committee and Section 16 Committee of its Board of Directors (jointly, the "Compensation Committees"). The March 2024 PSU awards provide for vesting in two equal annual installments on each of December 31, 2025 and December 31, 2026, if and to the extent the Company achieves pre-determined revenue and Adjusted EBITDA metrics (each weighted 50%) established by the Compensation Committees. The estimated grant-date fair values per PSU were 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.

[1] Our revenue is recognized primarily at a point in time for all reportable segments. Includes a one-time charge of $ 4 million during the second quarter of 2024, resulting from enacted tax legislation in Canada during June 2024 related to digital services taxes, which requires retrospective application back to January 1, 2022. This amount represents the one-time retrospective liability for the periods prior to April 1, 2024, while all prospective periods are and will be included within Adjusted EBITDA, respectively. In addition, this amount includes an estimated accrual for the potential settlement of a regulatory related matter of $ 10 million, expensed during the first quarter of 2024. Refer to "Note 9: Commitments and Contingencies " for further information. These costs are reflected in general and administrative expenses on our unaudited condensed consolidated statement of operations.

The Company expensed certain transaction related costs of $ 1 million and $ 4 million during the three and nine months ended September 30, 2024 , respectively, to general and administrative expenses on our unaudited condensed consolidated statement of operations.
