Exhibit 10.4

TRIPADVISOR, INC. RESTRICTED STOCK UNIT AGREEMENT

(Performance Based)

THIS RESTRICTED STOCK UNIT AGREEMENT (this “Agreement”), dated as of the grant date specified on the Grant Details referenced below (the “Grant Date”), between Tripadvisor, Inc., a Delaware corporation (the “Company”), and the employee, director or consultant of the Company or one of its Subsidiaries or Affiliates designated on the Grant Details (as defined below) (the “Eligible Individual”), describes the terms of an award (the “Award”) of performance-based restricted stock units (“PSUs”) to the Eligible Individual by the Company.

All capitalized terms used herein, to the extent not defined, shall have the meanings set forth in the Company’s 2023 Stock and Annual Incentive Plan (as amended from time to time, the “Plan”).

1.Award and Vesting of PSUs

(a) Subject to the terms and conditions of this Agreement, the Plan and the Grant Details, the Company grants a target number of PSUs to the Eligible Individual (“Target PSUs”). The actual number of PSUs earned pursuant to this Agreement (the “Earned PSUs”) will be based on the extent to which the revenue and adjusted EBITDA performance metrics established by the Company (the “Performance Metrics”) are achieved relative to the targets over the two-year performance period beginning on January 1, 2024 and ending on December 31, 2025 (the “Performance Period”) and may be more or less than the Target PSUs. Each Performance Metric is weighted 50%. In no event will the number of Earned PSUs exceed 200% of the Target PSUs. Reference is made to the “Grant Details” that can be found on the equity plan website of the current professional selected by the Company to administer the Plan (the “Plan Administrator”), currently located at www.netbenefits.fidelity.com (or any successor equity administration system selected by the Company to manage the Plan from time to time), which are hereby incorporated by reference into, and shall be read as part and parcel of, this Agreement.

(b)The number of Earned PSUs shall be calculated following the completion of the Performance Period. No PSUs will be earned or vest unless the Company achieves at least 90% of either of the Performance Metric targets for the Performance Period. If the Company achieves 105% or more of both Performance Metric targets, then 200% of the Target PSUs will become Earned PSUs. In no event may more than 200% of the Target PSUs be earned and vest.

(c)Within 60 days of the completion of the Performance Period, the Committee will determine in its sole discretion the extent to which the Performance Metrics have been satisfied. The day the Committee certifies the extent to which the Performance Metrics have been satisfied is the “Determination Date”.

(d)Subject to the terms and conditions of this Agreement, the Grant Details, and the Plan, the Earned PSUs will vest 50% on the Determination Date, and the remaining 50% on December 31, 2026. The time during which restrictions apply shall be referred to as the “PSU Restriction Period”.

2.Termination of Employment by the Company for Cause

Version March 2024

(a)Notwithstanding the provisions of Section 1(d) above, in the event the Eligible Individual incurs a Termination of Employment by the Company or any Subsidiary or Affiliate for Cause, or the Eligible Individual voluntarily incurs a Termination of Employment within two years after any event or circumstance that would have been grounds for a Termination of Employment for Cause, the Eligible Individual’s unvested PSUs shall be forfeited and canceled in their entirety upon such Termination of Employment.

(b)For purposes of this Agreement, employment with the Company shall include employment with the Company’s Subsidiaries or Affiliates. The Committee shall have the exclusive discretion to determine whether there has been any Termination of Employment and/or whether and when grounds for a Termination of Employment for Cause existed.

3.Settlement of PSUs

As soon as practicable after any PSUs have vested and are no longer subject to the PSU Restriction Period (but in no event later than thirty (30) days thereafter or, in the case of PSUs that vest on the Determination Date, no later than March 15 of the year following the end of the Performance Period), such PSUs shall be settled (“Settlement Date”). Subject to Section 10 (pertaining to the withholding of taxes), for each PSU settled pursuant to this Section 3, the Company shall issue one Share for each vested PSU and cause to be delivered to the Eligible Individual one or more unlegended, freely-transferable stock certificates in respect of such Shares issued upon settlement of the vested PSUs. Notwithstanding the foregoing, the Company shall be entitled to hold the Shares issuable upon settlement of PSUs that have vested until the Company or Plan Administrator shall have received from the Eligible Individual a duly executed Form W-9 or Form W-8, as applicable, as well as such other documents as may be legally required.

4.Recoupment or “Clawback” Policy

All awards received and any shares or other amount or property that may be issued, delivered, or paid in respect of the Award, as well as any consideration that may be received in respect of a sale or other disposition of any such shares or property, will be subject to clawback, cancellation, recoupment, rescission, payback, reduction, or other similar action in accordance with the Company’s Clawback Policy (as in effect from time to time and any successor policies) or similar policy or any applicable law related to such actions. An Eligible Individual’s acceptance of an Award will constitute the Eligible Individual’s acknowledgment of and consent to the Company’s application, implementation, and enforcement of the Company’s Clawback Policy or similar policy that may apply to the Eligible Individual, whether adopted before or after the Grant Date, and any applicable law relating to clawback, cancellation, recoupment, rescission, payback, or reduction of compensation, and the Eligible Individual’s agreement that the Company may take any actions that may be necessary to effectuate any such policy or applicable law, without further consideration or action.

5.Non-Transferability of the PSUs

Until the PSUs are settled as provided herein or on the website of the Plan Administrator, the PSUs shall not be transferable by the Eligible Individual by means of sale, assignment, exchange, encumbrance, pledge, hedge or otherwise.

6.Rights as a Stockholder

Except as otherwise specifically provided in this Agreement, until the PSUs have vested and settled in Shares, the Eligible Individual shall not be entitled to any rights of a stockholder with respect to the PSUs. Notwithstanding the foregoing, if the Company declares and pays ordinary cash dividends on the Common Stock prior to the time that the PSUs are settled, the Eligible Individual will be credited with additional amounts for each PSU equal to the dividend that would have been paid with respect to such PSU if it had been an actual share of Common Stock, which amount shall remain subject to restrictions (and as determined by the Committee may be reinvested in PSUs or may be held in kind as restricted property) and shall vest concurrently with the vesting of the PSUs upon which such dividend equivalent amounts were paid. Notwithstanding the foregoing, dividends and distributions other than ordinary cash dividends, if any, may result in an adjustment pursuant to Section 7 below, rather than under this Section 6.

7.Adjustment in the Event of Change in Stock; Change in Control

(a)In the event of (i) a stock dividend, stock split, reverse stock split, share combination or recapitalization or similar event affecting the capital structure of the Company (each, a “Share Change”), or (ii) a merger, consolidation, acquisition of property or shares, separation, spinoff, reorganization, stock rights offering, liquidation, Disaffiliation, payment of a dividend other than an ordinary dividend, or similar event affecting the Company or any of its Subsidiaries (each, a “Corporate Transaction”), the Committee or the Board, may in its discretion make such substitutions or adjustments as it deems appropriate and equitable to the number of PSUs and the number and kind of shares of Common Stock underlying the PSUs.

(b)In the case of Corporate Transactions, such adjustments may include, without limitation (i) the cancellation of the PSUs in exchange for payments of cash, property or a combination thereof having an aggregate value equal to the value of such PSUs, as determined by the Committee or the Board in its sole discretion, (ii) the substitution of other property (including, without limitation, cash or other securities of the Company and securities of entities other than the Company) for the shares of Common Stock underlying the PSUs and (iii) in connection with any Disaffiliation, arranging for the assumption of the PSUs, or the replacement of the PSUs with new Awards based on other property or other securities (including, without limitation, other securities of the Company and securities of entities other than the Company), by the affected Subsidiary or Affiliate or by the entity that controls such Subsidiary or Affiliate following such Disaffiliation (as well as any corresponding adjustments to any PSUs that remain based upon securities of the Company).

(c)In the event of a Change in Control:

(i)Before the Determination Date, the Target PSUs will be deemed earned and will vest 50% on December 31, 2025, and 50% on December 31, 2026, subject to any substitutions or adjustments made pursuant to this Section 7.

Version March 2024

(ii)After the Determination Date, the PSU Award will be calculated and will vest in accordance with Section 1, subject to any substitutions or adjustments made pursuant to this Section 7.

(d)The determination of the Committee regarding any substitutions or adjustment or the amount of PSUs awarded, vested and/or distributed pursuant to this Section need not be the same for all Participants and will be final and conclusive.

(e)In the event of a Termination of Employment during the three (3) months prior to or twelve (12) months following a Change in Control (the “CIC Period”), the provisions of Section 13 of the Plan shall apply; provided, however, that the Committee in its discretion may provide for earlier accelerated vesting.

8.Termination of Employment without Cause or Resignation for Good Reason

(a)In the event of Termination of Employment without Cause or resignation for Good Reason, not in connection with a Change in Control, a pro-rated portion of Target PSUs determined by multiplying the Target PSUs by a fraction, the numerator of which is the number of days the Eligible Individual worked during the Performance Period and the denominator is the total number of days in the Performance Period, will be deemed earned and will vest in accordance with the vesting schedule described in Section 1 above.

(b)In the event of Termination of Employment without Cause or resignation for Good Reason in connection with a Change in Control that occurs (i) before the Determination Date and (ii) during the CIC Period, the Target PSUs will be deemed earned and will accelerate and vest as of the date of the Termination of Employment.

(c)In the event of Termination of Employment without Cause or resignation for Good Reason in connection with a Change in Control that occurs (i) after the Determination Date and (ii) within the CIC Period, the Earned PSUs will accelerate and vest as of the date of the Termination of Employment.

9.Death or Disability

(a)In the event of a Termination of Employment due to the Eligible Individual’s death or Disability, as defined in the Plan, occurring before the Determination Date, the Target PSUs will be deemed earned and will accelerate and vest as of the date of the Termination of Employment.

(b)In the event of a Termination of Employment due to the Eligible Individual’s death or Disability occurring after the Determination Date, all Earned PSUs will accelerate and vest as of the date of the Termination of Employment.

Version March 2024

10.Taxes, Fees and Withholding

(a)The Company agrees to pay any and all original issue taxes and stock transfer taxes that may be imposed on the issuance of shares received by an Eligible Individual in connection with the PSUs, together with any and all other fees and expenses necessarily incurred by the Company in connection therewith.

(b)Regardless of any action taken by the Company, its Affiliate or Subsidiary with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related withholding (“Tax-Related Items”), the Eligible Individual acknowledges that the ultimate liability for all Tax-Related Items legally due by him or her is and remains the Eligible Individual’s responsibility and that the Company and/or its Affiliate or Subsidiary (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Award, including the grant and vesting of the PSUs and the receipt of cash or any dividends or dividend equivalents with respect thereto; and (ii) do not commit to structure the terms of the Award or any aspect of the PSUs to reduce or eliminate the Eligible Individual’s liability for Tax-Related Items.

(c)In the event that the Company, Subsidiary or Affiliate is required to withhold any Tax-Related Items as a result of the Award or vesting of the PSUs, or the receipt of cash or any dividends or dividend equivalents, the Eligible Individual shall pay or make adequate arrangements satisfactory to the Company, Subsidiary or Affiliate to satisfy all withholding and payment on account of obligations of the Company, Subsidiary and/or Affiliate. The obligations of the Company under this Agreement shall be conditioned on compliance by the Eligible Individual with this Section 10. In this regard, the Eligible Individual authorizes the Company and/or its Subsidiary or Affiliate to withhold all applicable Tax-Related Items legally payable by the Eligible Individual from his or her wages or other cash compensation paid to the Eligible Individual by the Company and/or its Subsidiary or Affiliate. In connection herewith, the Eligible Individual (i) authorizes, empowers and directs the Company and the Plan Administrator (or such brokerage firm as is contracted to manage the Company’s employee equity award program, the “Broker”) to sell, at the market price and on the Exercise Date or as soon thereafter as is practicable, the number of Shares sufficient to pay the Tax-Related Items, and (ii) agrees to indemnify and hold harmless the Broker and the Company from and against all losses, liabilities, damages, claims and expenses, including reasonable attorneys’ fees and court costs, arising out of carrying out such actions. Finally, the Eligible Individual will pay to the Company any amount of Tax-Related Items that the Company may be required to withhold as a result of the Eligible Individual’s participation in the Plan or the Eligible Individual’s Award that cannot be satisfied by the means previously described. The Company may refuse to deliver the Shares underlying the PSU if the Eligible Individual fails to comply with his or her obligations in connection with the Tax-Related Items as described in this Section.

11.Other Restrictions

(a) The Award shall be subject to the requirement that, if at any time the Committee shall determine that (i) the listing, registration or qualification of the shares of Common Stock subject or related thereto upon any securities exchange or under any state or federal law, or (ii) the consent or approval of any government regulatory body is required, then in any such event, the

Version March 2024

5

Award shall not be effective unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Committee.

(b) The Eligible Individual acknowledges that the Eligible Individual is subject to the Company’s policies regarding compliance with securities laws, including but not limited to its Insider Trading Policy (as in effect from time to time and any successor policies), and, pursuant to these policies, if the Eligible Individual is on the Company’s insider list, the Eligible Individual shall be required to obtain pre-clearance from the Company’s Chief Compliance Officer prior to purchasing or selling any of the Company’s securities, including any shares issued upon vesting of the PSUs, and may be prohibited from selling such shares other than during an open trading window. The Eligible Individual further acknowledges that, in its discretion, the Company may prohibit the Eligible Individual from selling such shares even during an open trading window if the Company has concerns over the potential for insider trading.

12.Nature of Award

(a)the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time, unless otherwise provided in the Plan and this Agreement;

(b)the Award is voluntary and occasional and does not create any contractual or other right to receive future Awards, or benefits in lieu of Awards, even if Awards have been made repeatedly in the past;

(c)all decisions with respect to future Awards, if any, will be at the sole discretion of the Company;

(d)the Eligible Individual’s participation in the Plan will not create a right to further employment or service with the Company, its Subsidiary or Affiliate and shall not interfere with the ability of the Company to terminate the Eligible Individual’s employment or service relationship at any time with or without Cause;

(f)the Award is not part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, end-of-service payments, bonuses, long-service awards, pension or retirement benefits or similar payments;

(g)in the event that the Eligible Individual is not an employee of the Company, a Subsidiary, or an Affiliate, the Award will not be interpreted to form an employment contract or relationship with the Company; and

(h)in consideration of the Award, no claim or entitlement to compensation or damages shall arise from termination of the Award or diminution in value of the Award resulting from the

Version March 2024

6

Eligible Individual’s Termination of Employment by the Company, Subsidiary or Affiliate (for any reason whatsoever and whether or not in breach of local labor laws) and the Eligible Individual irrevocably releases the Company, Subsidiary or Affiliate from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, then, by signing this Agreement, the Eligible Individual will be deemed irrevocably to have waived his or her entitlement to pursue such claim.

The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Eligible Individual’s participation in the Plan, or his or her acquisition or sale of the underlying Shares.

The Committee shall not be personally responsible for any action, determination or interpretation made in good faith with respect to the Plan or this Agreement.

The Eligible Individual hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of his or her Data as described in this document by and among, as applicable, the Company and its Subsidiaries or Affiliates for the exclusive purpose of implementing, administering and managing the Eligible Individual’s participation in the Plan.

(b)This Award and payments made pursuant to this Agreement and the Plan are intended to qualify for an exemption from, or comply with, Section 409A of the Code. If the Company makes a good faith determination that any compensation provided under this Agreement is likely to be subject to the additional tax imposed by Section 409A of the Code, the Company may, to the extent it deems necessary or advisable, modify this Agreement, without the Eligible Individual’s consent, to reduce the risk that such additional tax will apply, in a manner designed to preserve the material economic benefits intended to be provided to the Eligible Individual under this Agreement (other than any diminution of such benefit that may be attributable to the time value of money resulting from a delay in the timing of payments hereunder for a period of approximately six months or such longer period as may be required).
