PRELIMINARY, SUBJECT TO COMPLETION, DATED MAY 1, 2019

TRANSACTION PROPOSED—YOUR VOTE IS VERY IMPORTANT

Dear Stockholders:

On April 15, 2019, Liberty Expedia Holdings, Inc., which is referred to as Liberty Expedia, Expedia Group, Inc., which is referred to as Expedia Group, LEMS I LLC, a wholly owned subsidiary of Expedia Group, which is referred to as Merger LLC, and LEMS II Inc., a wholly owned subsidiary of Merger LLC, which is referred to as Merger Sub, entered into an Agreement and Plan of Merger, which (as the same may be amended from time to time) is referred to as the merger agreement, that provides for the acquisition of Liberty Expedia by Expedia Group. Subject to approval of Liberty Expedia stockholders and the satisfaction or (to the extent permitted by law) waiver of certain other closing conditions, Expedia Group will acquire Liberty Expedia through the merger of Merger Sub with and into Liberty Expedia, which is referred to as the first merger, with Liberty Expedia surviving the first merger and becoming a wholly owned subsidiary of Expedia Group. Immediately following the first merger, Liberty Expedia as the surviving corporation of the first merger will merge with and into Merger LLC, which is referred to as the upstream merger and, together with the first merger, the mergers, with Merger LLC surviving the upstream merger as a wholly owned subsidiary of Expedia Group.

If the mergers are completed, each share of Liberty Expedia Series A common stock and Liberty Expedia Series B common stock (other than shares held by Liberty Expedia as treasury stock or held directly by Expedia Group), which are referred to collectively as Liberty Expedia common stock, will be converted into the right to receive 0.36 of a share of Expedia Group common stock, with cash (without interest) paid in lieu of any fractional shares of Expedia Group common stock, which is referred to as the merger consideration. For more details on the merger consideration, see “The Merger Agreement—Merger Consideration” beginning on page 63. U.S. holders (as defined under “The Transaction—Material U.S. Federal Income Tax Consequences” beginning on page 59) of Liberty Expedia common stock are not expected to recognize gain or loss for U.S. federal income tax purposes as a result of the exchange of Liberty Expedia common stock for Expedia Group common stock pursuant to the mergers, except with respect to any cash received in lieu of fractional shares of Expedia Group common stock. See “The Transaction—Material U.S. Federal Income Tax Consequences” beginning on page 59 for a more complete discussion of the U.S. federal income tax consequences of the mergers.

If the Expedia Group stock price at the closing of the mergers is equal to the closing price of Expedia Group common stock on April 29, 2019, the most recent practicable date for which such information was available, holders of Liberty Expedia common stock would receive merger consideration with an implied value of approximately $46.79 per share of Liberty Expedia common stock. The actual value of the merger consideration as of the completion of the mergers may well differ from this example. The common stock of Expedia Group is listed on the Nasdaq Global Select Market under the symbol “EXPE.” The Series A common stock and the Series B common stock of Liberty Expedia are listed on the Nasdaq Global Select Market under the symbols “LEXEA” and “LEXEB,” respectively. We urge you to obtain current market quotations for the shares of common stock of Expedia Group and the shares of Series A common stock and Series B common stock of Liberty Expedia.

Liberty Expedia is holding a special meeting of its stockholders to vote on the proposals necessary to complete the mergers. In connection with the transactions contemplated by the merger agreement, the Malone group, which consists of John C. Malone and Leslie Malone, and Expedia Group entered into a Voting Agreement, dated as of April 15, 2019, pursuant to which the Malone group has committed to vote shares of Liberty Expedia common stock representing approximately 32% of the total voting power of the issued and outstanding shares of Liberty Expedia common stock as of February 28, 2019 in favor of the approval of the merger agreement and the transactions contemplated thereby. The voting agreement is described in more detail in “The Voting Agreement” beginning on page 95. Information about the special meeting, the mergers and the other business to be considered by Liberty Expedia stockholders at the special meeting is contained in this proxy statement/prospectus. Any stockholder entitled to attend and vote at the special meeting is entitled to appoint a proxy to attend and vote on such stockholder’s behalf. Such proxy need not be a holder of Liberty Expedia common stock. We urge you to read this proxy statement/prospectus and the annexes and documents incorporated by reference carefully. You should also carefully consider the risks that are described in the “Risk Factors” section beginning on page 27.

Your vote is very important regardless of the number of shares of Liberty Expedia common stock that you own. The mergers cannot be completed without the approval of the adoption of the merger agreement by the affirmative vote of the holders of a majority of the combined voting power of the shares of Liberty Expedia common stock outstanding and entitled to vote at the special meeting, voting together as a single class. A failure to vote your shares, or to provide instructions to your broker, bank or nominee as to how to vote your shares, is the equivalent of a vote against the proposal to approve the adoption of the merger agreement.

Whether or not you plan to attend the special meeting of stockholders, please submit your proxy as soon as possible to make sure that your shares are represented at the meeting.

Very truly yours,
   
[                ]

TABLE OF CONTENTS

QUESTIONS & ANSWERS ABOUT THE TRANSACTION AND THE SPECIAL MEETING

The following questions and answers briefly address some commonly asked questions about the transaction, the merger agreement and the special meeting. They may not include all the information that is important to stockholders of Liberty Expedia. Liberty Expedia stockholders should carefully read this entire proxy statement/prospectus, including the annexes and the other documents referred to or incorporated by reference herein.

The merger agreement contains the terms and conditions of the proposed acquisition of Liberty Expedia by Expedia Group. Under the merger agreement, subject to satisfaction or (to the extent permitted by law) waiver of the conditions set forth in the merger agreement and described hereinafter, Merger Sub will merge with and into Liberty Expedia, with Liberty Expedia surviving as the surviving corporation and a wholly owned subsidiary of Expedia Group, which is referred to as the first merger, and, immediately thereafter, Liberty Expedia as the surviving corporation of the first merger will merge with and into Merger LLC, with Merger LLC surviving as a wholly owned subsidiary of Expedia Group, which is referred to as the upstream merger and, together with the first merger, the mergers. As a result of the mergers, Liberty Expedia will no longer be a publicly held company. Following the mergers, Liberty Expedia Series A common stock and Liberty Expedia Series B common stock, which are referred to collectively as Liberty Expedia common stock, will be delisted from the Nasdaq Global Select Market, which is referred to as NASDAQ, and deregistered under the Exchange Act. The merger agreement is described in more detail in “The Merger Agreement” beginning on page 63.

The exchange agreement contains the terms and conditions of the proposed exchange, which is referred to as the exchange, immediately preceding and conditioned upon the closing of the mergers by Mr. Diller and, if the Family Foundation so elects, the Family Foundation, with Liberty Expedia of up to a specified number of shares of Expedia Group common stock for the same number of shares of Expedia Group Class B common stock held by Liberty Expedia. The exchange agreement is described in more detail in “The Exchange Agreement” beginning on page 78.

The new governance agreement contains the terms and conditions of certain governance arrangements following the mergers between Expedia Group and Mr. Diller, including the right, which is referred to as the purchase/exchange right, for the nine months following the closing of the mergers of Mr. Diller to either exchange with Expedia Group (or its wholly owned subsidiary) an equivalent number of shares of Expedia Group common stock for, or purchase from Expedia Group (or its wholly owned subsidiary), up to a specified number of shares of Expedia Group Class B common stock. The new governance agreement is described in more detail in “The New Governance Agreement” beginning on page 83.

In connection with the transactions contemplated by the merger agreement, the Malone group and Expedia Group entered into a Voting Agreement, dated as of April 15, 2019, which is referred to as the voting agreement. Pursuant to the voting agreement, the Malone group has committed to vote shares of Liberty Expedia common stock representing approximately 32% of the total voting power of the issued and outstanding shares of Liberty Expedia common stock as of February 28, 2019 in favor of the approval of the merger agreement and the transactions contemplated thereby. The voting agreement is described in more detail in “The Voting Agreement” beginning on page 95.

Certain other agreements have been entered into in connection with the transaction, including certain termination agreements and joinder agreements, which are described in more detail in “Additional Transaction Agreements” beginning on page 93.

The transactions contemplated by the merger agreement, the exchange agreement and the new governance agreement, including the mergers, the exchange and the purchase/exchange right, are referred to as the transaction. The merger agreement, the exchange agreement, the joinder agreements and certain termination agreements are referred to as the transaction documents.

The transaction cannot be completed unless Liberty Expedia stockholders approve the adoption of the merger agreement. Liberty Expedia is holding a special meeting of its stockholders to vote on the proposals necessary to complete the transaction. Information about the special meeting, the transaction, the merger agreement and the other business to be considered by Liberty Expedia stockholders at the special meeting is contained in this proxy statement/prospectus.

This proxy statement/prospectus constitutes both a proxy statement of Liberty Expedia and a prospectus of Expedia Group. It is a proxy statement because the Liberty Expedia board of directors, which is referred to as the Liberty Expedia Board, is soliciting proxies from its stockholders. It is a prospectus because Expedia Group will issue shares of its common stock upon the conversion of the outstanding shares of Liberty Expedia common stock in the mergers. This proxy statement/prospectus includes important information about the mergers, the merger agreement and the special meeting. Liberty Expedia stockholders should read this information carefully and in its entirety. The enclosed voting materials allow Liberty Expedia stockholders to vote their shares by proxy without attending the special meeting in person.

All fractional shares of Expedia Group common stock that would otherwise be issued to a Liberty Expedia stockholder of record as part of the merger consideration will be aggregated and the shares resulting from such aggregation will be sold at prevailing market prices on behalf of Liberty Expedia stockholders who otherwise would have been entitled to receive such fractional shares. Each such Liberty Expedia stockholder will be paid, in lieu of such fractional share of Expedia Group common stock, an amount in cash, without interest, in proportion to the stockholder’s corresponding pro rata portion.

See “The Merger Agreement—Conditions to the Mergers” beginning on page 74.

Approval of the merger proposal by Liberty Expedia stockholders is required for completion of the mergers. The consummation of the mergers is not conditioned on the approval of the merger-related compensation proposal or the adjournment proposal. Because the vote on the merger-related compensation proposal is advisory only, it will not be binding on either Liberty Expedia or Expedia Group. Accordingly, if the merger proposal is approved and the mergers are completed, the merger-related compensation will be payable to Liberty Expedia’s named executive officers, subject only to the conditions applicable thereto, regardless of the outcome of the approval of the merger-related compensation proposal.

The merger-related compensation proposal and the adjournment proposal: The affirmative vote of the holders of a majority of the combined voting power of shares of Liberty Expedia common stock that are present in person or represented by proxy at the special meeting and entitled to vote on such proposal, voting together as a single class, assuming a quorum is present, is required to approve each of the merger-related compensation proposal and the adjournment proposal.

Pursuant to the voting agreement, the Malone group has committed to vote shares of Liberty Expedia common stock representing approximately 32% of the total voting power of the issued and outstanding shares of Liberty Expedia common stock as of February 28, 2019 in favor of the approval of the merger agreement and the transactions contemplated thereby. The voting agreement is described in more detail in “The Voting Agreement” beginning on page 95.

As of 5:00 p.m., New York City time, on the record date, there were approximately [          ] shares of Liberty Expedia Series A common stock outstanding and [          ] shares of Liberty Expedia Series B common stock outstanding. As summarized below, there are some important distinctions between shares held of record and those owned beneficially in street name. See “The Special Meeting—Voting of Proxies by Holders of Record” beginning on page 98 and “The Special Meeting—Shares Held in Street Name” beginning on page 98.

Pursuant to the voting agreement, the Malone group has committed to vote shares of Liberty Expedia common stock representing approximately 32% of the total voting power of the issued and outstanding shares of Liberty Expedia common stock as of February 28, 2019 in favor of the approval of the merger agreement and the transactions contemplated thereby. The voting agreement is described in more detail in “The Voting Agreement” beginning on page 95.

Because applicable NASDAQ rules do not permit discretionary voting by brokers with respect to any of the proposals to be acted upon at the special meeting, if you hold your shares through banks or brokers, your shares of Liberty Expedia common stock will not count as present and entitled to vote for purposes of determining a quorum, unless you instruct your bank or broker on how to vote your shares. This may make it more difficult to establish a quorum at the special meeting.

Please do not submit your stock certificates at this time. If the mergers are completed, you will receive instructions for surrendering your stock certificates in exchange for shares of Expedia Group common stock from the exchange agent.

The merger-related compensation proposal and the adjournment proposal must be approved by the affirmative vote of the holders of a majority of the combined voting power of shares of Liberty Expedia common stock that are present in person or represented by proxy at the special meeting and entitled to vote on such proposal, voting together as a single class, assuming a quorum is present. The consummation of the mergers is not conditioned on the approval of the merger-related compensation proposal or the adjournment proposal. Because the vote to approve such compensation is advisory only, it will not be binding on either Liberty Expedia or Expedia Group. An abstention will have the same effect as a vote “AGAINST” the merger-related compensation proposal and the adjournment proposal. If a stockholder is not present in person at the special meeting and does not respond by proxy, it will have no effect on the outcome of the merger-related compensation proposal or the adjournment proposal (assuming a quorum is present). The Liberty Expedia Board unanimously recommends that Liberty Expedia stockholders vote “FOR” each of the merger-related compensation proposal and the adjournment proposal.

If you are a stockholder of record, you may also vote in person at the special meeting.

If your shares are held in “street name,” through a broker, bank or other nominee, that institution will send you separate instructions describing the procedure for voting your shares. “Street name” Liberty Expedia stockholders who wish to vote at the meeting will need to obtain a “legal proxy” form from their broker, bank or other nominee.

other nominee or other similar organization. Your bank, brokerage firm or other nominee will send you, as the beneficial owner, a package describing the procedure for voting your shares. You should follow the instructions provided by them to vote your shares. If you beneficially own your shares, you are invited to attend the special meeting; however, you may not vote your shares in person at the special meeting unless you obtain a “legal proxy” from your bank, brokerage firm or other nominee that holds your shares, giving you the right to vote the shares at the special meeting.

Brokers who hold shares in street name for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are not allowed to exercise their voting discretion with respect to the approval of matters determined to be “non-routine” without specific instructions from the beneficial owner. It is expected that all of the proposals to be voted on at the special meeting are “non-routine” matters.

If you are a beneficial owner of shares of Liberty Expedia common stock and you do not instruct your broker, bank or other nominee on how to vote your shares:

If you wish to attend the special meeting, you must bring photo identification. If you hold your shares through a broker, bank or other nominee, you must also bring proof of ownership such as the voting instruction form from your broker or other nominee or an account statement.

Merger proposal: An abstention will have the same effect as a vote “AGAINST” the merger proposal. If a stockholder is not present in person at the special meeting and does not respond by proxy, it will have the same effect of a vote “AGAINST” such proposal.

Merger-related compensation proposal and adjournment proposal: An abstention will have the same effect as a vote “AGAINST” the merger-related compensation proposal and the adjournment proposal. If a stockholder is not present in person at the special meeting and does not respond by proxy, it will have no effect on the outcome of the merger-related compensation proposal or the adjournment proposal (assuming a quorum is present).

Any signed proxy revocation or new signed proxy must be received before the beginning of the special meeting. In addition, you may change your vote through the Internet or by telephone (if you originally voted by the corresponding method) not later than 11:59 p.m., New York City time, on [               ].

Holders of Liberty Expedia common stock should read the section entitled “The Transaction—Material U.S. Federal Income Tax Consequences” beginning on page 59 for a more complete discussion of the U.S. federal income tax consequences of the mergers. This proxy statement/prospectus contains a general discussion of the U.S. federal income tax consequences of the mergers. Tax matters can be complicated, and the tax consequences to a particular holder will depend on such holder’s particular facts and circumstances. This proxy statement/prospectus does not address any non-U.S. tax consequences, nor does it pertain to state or local income or other tax consequences of the mergers. Liberty Expedia stockholders should consult their own tax advisors to determine the specific consequences to them of receiving Expedia Group common stock pursuant to the mergers, as well as the specific tax consequences to them under any state, local or non-U.S. income or other tax laws.

closing of the mergers or any of the other transactions contemplated by the merger agreement and related transaction documents, (3) the approval for listing of the shares of Expedia Group common stock to be issued in connection with the mergers on NASDAQ and the effectiveness under the Securities Act of the registration statement on Form S-4 of which this proxy statement/prospectus forms a part and (4) the delivery of an opinion by Skadden, Arps, Slate, Meagher & Flom LLP, which is referred to as Skadden, to Liberty Expedia regarding certain tax matters related to the split-off of Liberty Expedia by Qurate Retail, Inc. (formerly known as Liberty Interactive Corporation, which is referred to as Qurate Retail), on November 4, 2016, which is referred to as the split-off.

The respective obligation of each party to consummate the mergers is also conditioned upon (x) the delivery of a reorganization tax opinion from such party’s tax counsel and (y) the other party’s representations and warranties being true and correct (subject to certain materiality and material adverse effect qualifications), and the other party having performed in all material respects its obligations under the merger agreement. Expedia Group’s obligation to consummate the mergers is further conditioned upon the satisfaction of certain conditions to the completion of the exchange pursuant to the exchange agreement.

The mergers do not require the approval of Expedia Group stockholders.

Liberty Expedia Holdings, Inc.

During November 2015, the board of directors of Qurate Retail authorized management to pursue a plan to distribute to holders of its Liberty Ventures common stock shares of a newly formed entity, Liberty Expedia Holdings, Inc. The split-off was completed on November 4, 2016. Immediately following the split-off, Liberty Expedia, a Delaware corporation, was comprised of, among other things, Qurate Retail’s former ownership interest in Expedia Group, as well as Qurate Retail’s former wholly-owned subsidiary, Vitalize, LLC (formerly known as Bodybuilding.com, LLC), which is referred to as Bodybuilding.

On April 15, 2019, and prior to Liberty Expedia’s entry into the merger agreement, Barry Diller, Liberty Expedia, Qurate Retail and the Malone group entered into Amendment No. 2 to the transaction agreement (as defined below), providing for the immediate termination of the transaction agreement, which automatically resulted in the termination of the proxy swap arrangements (as defined below). As a result of the termination of the transaction agreement and the proxy swap arrangements, as of April 15, 2019, Liberty Expedia no longer controls a majority of the voting interest in Expedia Group and will not consolidate their results from the termination date forward. Due to the rights allowed under the existing governance agreement and existing stockholders agreement (each as defined below) Liberty Expedia will continue to account for its investment in Expedia Group as an equity method affiliate and expects to elect the fair value option of accounting.

The Transaction

The principal terms and conditions of the transaction are contained in the merger agreement, the exchange agreement and the new governance agreement, copies of which are attached as Annex A, Annex B and Annex C, respectively, to this proxy statement/prospectus. We encourage you to read each agreement carefully and in its entirety, as these are the legal documents that govern the transaction, including the mergers, the exchange and the purchase/exchange right.

The Mergers

On April 15, 2019, Expedia Group, Liberty Expedia, Merger Sub and Merger LLC entered into the merger agreement, which provides that, subject to the terms and conditions of the merger agreement and in accordance with the General Corporation Law of the State of Delaware, which is referred to as the DGCL, Merger Sub will merge with and into Liberty Expedia, with Liberty Expedia surviving as the surviving corporation and an indirect wholly owned subsidiary of Expedia Group, and, immediately thereafter, Liberty Expedia as the surviving corporation of the first merger will merge with and into Merger LLC, with Merger LLC surviving as a direct wholly owned subsidiary of Expedia Group. As a result of the mergers, Liberty Expedia will no longer be a publicly-held company. Following the mergers, Liberty Expedia Series A common stock and Liberty Expedia Series B common stock will be delisted from NASDAQ and deregistered under the Exchange Act.

Pursuant to the merger agreement, Liberty Expedia is required to use reasonable best efforts to cause each of the three directors serving on the Expedia Group Board who were nominated by Liberty Expedia to resign from the Expedia Group Board.

The merger agreement is described in more detail in “The Merger Agreement” beginning on page 63.

The Pre-Mergers Exchange

On April 15, 2019, Expedia Group, Liberty Expedia, Mr. Diller and the Family Foundation entered into the exchange agreement, which provides that, subject to the terms and conditions of the exchange agreement, immediately prior to and conditioned upon the satisfaction of the conditions to the closing of the mergers, Mr. Diller and, if the Family Foundation so elects, the Family Foundation, will exchange with Liberty Expedia up to approximately 5.7 million (based on the net exercise of Mr. Diller’s 537,500 vested options assuming an Expedia Group common stock price of $129.98, the closing price of Expedia Group common stock on April 29, 2019) shares of Expedia Group common stock for the same number of shares of Expedia Group Class B common stock held by Liberty Expedia, which shares are referred to as original shares. Such original shares represent approximately 29% of the total voting power of Expedia Group based on approximately 140 million shares of Expedia Group common stock and approximately 5.7 million shares of Expedia Group Class B common stock currently expected to be outstanding at the closing of the mergers. The exchange agreement is described in more detail in “The Exchange Agreement” beginning on page 78.

The New Governance Agreement & Post-Mergers Purchase/Exchange Right

On April 15, 2019, Expedia Group and Mr. Diller entered into the new governance agreement, which provides for, subject to the terms and conditions of the new governance agreement, certain governance arrangements following the mergers, including the purchase/exchange right of Mr. Diller for the nine months following the closing of the mergers to either exchange with Expedia Group (or its wholly owned subsidiary) an equivalent number of shares of Expedia Group common stock for, or purchase from Expedia Group (or its wholly owned subsidiary), up to a number of shares of Expedia Group Class B common stock equal to (1) 12,799,999 minus (2) the number of original shares, which are referred to as additional shares. The purchase/exchange right may be exercised from time to time and in whole or in part. Assuming the exercise in full by Mr. Diller of the purchase/exchange right, the original shares and additional shares would collectively represent approximately 49% of the total voting power of all outstanding shares of Expedia Group common stock and Expedia Group Class B common stock, assuming a total of approximately 133 million shares of Expedia Group common stock and 12,799,999 shares of Expedia Group Class B common stock outstanding immediately following the exercise of the purchase/exchange right. The foregoing assumes that Mr. Diller exercises his right to acquire the additional shares solely by exchanging shares of Expedia Group common stock acquired in the open market (or otherwise). If Mr. Diller acquires the additional shares through cash purchases directly from Expedia Group (or its wholly owned subsidiary), the original shares and additional shares would collectively represent approximately 48% of the total voting power of all outstanding shares of Expedia Group common stock and Expedia Group Class B common stock.

Prior to the transfer of any additional shares, a transferee must deliver a proxy granting Mr. Diller sole voting control over such shares and deliver a joinder agreement to be bound by certain terms of the new governance agreement. Subject to limited exceptions, any transferred additional shares over which Mr. Diller does not maintain sole voting control will be automatically converted into shares of Expedia Group common stock.

Pursuant to the new governance agreement, upon certain events, including (a) Mr. Diller’s death or disability, (b) Mr. Diller voluntarily ceasing to serve as chairman or senior executive of Expedia Group, or (c) Mr. Diller or the Family Foundation transferring original shares exceeding 5% of the outstanding voting power of Expedia Group, all additional shares will automatically convert into shares of Expedia Group common stock. Therefore, following such automatic conversion event, it is currently expected that the number of outstanding shares of Expedia Group Class B common stock will not exceed the approximately 5.7 million original shares.

The new governance agreement also provides that, subject to limited exceptions, no current or future holder of original shares or additional shares may participate in, or vote or tender in favor of, any change of control transaction involving at least 50% of the outstanding shares of capital stock of Expedia Group, unless such transaction provides for the same per share consideration and mix of consideration (or election right) and the same participation rights for shares of Expedia Group Class B common stock and shares of Expedia Group common stock.

The new governance agreement is described in more detail in “The New Governance Agreement” beginning on page 83.

The Voting Agreement

In connection with the transactions contemplated by the merger agreement, the Malone group entered into the voting agreement with Expedia Group on April 15, 2019. Pursuant to the voting agreement, the Malone group has committed to vote shares of Liberty Expedia common stock representing approximately 32% of the total voting power of the issued and outstanding shares of Liberty Expedia common stock as of February 28, 2019 as follows:

Subject to certain conditions, the Malone group has granted the General Counsel of Expedia Group an irrevocable proxy to vote his or her shares of Liberty Expedia common stock in accordance with the voting agreement. The Malone group has also agreed not to transfer its shares of Liberty Expedia common stock prior to receipt of the Liberty Expedia stockholder approval without Expedia Group’s and Liberty Expedia’s consent, subject to certain exceptions.

Under the voting agreement, Expedia Group has agreed to indemnify the Malone group for losses in connection with or arising out of the voting agreement, including, subject to certain conditions, up to $750,000 of the reasonable fees and expenses of separate counsel of the Malone group incurred in the defense of any claim related to the voting agreement brought by a third party.

The voting agreement is described in more detail in “The Voting Agreement” beginning on page 95.

Additional Transaction Agreements & Governance Post-Mergers

Additionally, in connection with the transaction, various other agreements have been entered into that alter the existing governance arrangements between or among Expedia Group, Liberty Expedia and certain other parties. As of immediately prior to the entry into the merger agreement, pursuant to the irrevocable proxy granted by Liberty Expedia to Mr. Diller under the Amended and Restated Stockholders Agreement, by and among Liberty Expedia, certain wholly owned subsidiaries of Liberty Expedia and Mr. Diller, as amended as of November 4, 2016, which is referred to as the existing stockholders agreement, Mr. Diller generally has the right to vote the shares of Expedia Group common stock and Expedia Group Class B common stock held by Liberty Expedia and its subsidiaries, which right is referred to as the Diller proxy and which shares represent approximately 53% of the total voting power of all shares of Expedia Group common stock and Expedia Group Class B common stock, based on a total of 136,007,689 shares of Expedia Group common stock and 12,799,999 shares of Expedia Group Class B common stock outstanding as of April 19, 2019. Pursuant to the Assignment Agreement, dated as of November 4, 2016, by and between Liberty Expedia and Mr. Diller, Mr. Diller assigned the Diller proxy to Liberty Expedia, which assignment is referred to as the Diller assignment, and, pursuant to the Proxy and Voting Agreement, dated as of November 4, 2016, by and among the Malone group and Mr. Diller, the Malone group granted a proxy over its shares in Liberty Expedia to Mr. Diller, which proxy is referred to as the Malone proxy. The Diller assignment and the Malone proxy are referred to collectively as the proxy swap arrangements.

On April 15, 2019 and prior to the entry into the merger agreement, Mr. Diller, Liberty Expedia, Qurate Retail and the Malone group entered into Amendment No. 2 to Amended and Restated Transaction Agreement,

which amends the Amended and Restated Transaction Agreement, dated as of September 22, 2016, by and among Mr. Diller, Liberty Expedia, Qurate Retail and the Malone group, as amended by the letter agreement dated as of March 6, 2018 (which is referred to as the transaction agreement), providing for the immediate termination of the transaction agreement, which automatically resulted in the termination of the proxy swap arrangements.

Simultaneously with Expedia Group’s entry into the merger agreement, certain additional related agreements were entered into, including:

See “Additional Transaction Agreements” beginning on page 93.

Mr. Diller has agreed and acknowledged that the rights granted by the exchange agreement and the new governance agreement are deemed to be in recognition and in lieu of Mr. Diller’s existing rights under the existing governance agreement and existing stockholders agreement.

After the completion of the mergers, it is expected that Expedia Group will no longer be a controlled company under applicable NASDAQ rules. Accordingly, following permitted phase-in periods, Expedia Group will be required, among other things, to have a majority of independent directors on its board of directors, a compensation committee consisting solely of independent directors and a director nomination process whereby directors are selected by a nominations committee consisting solely of independent directors or by a vote of the board of directors in which only independent directors participate.

Merger Consideration

At the time that the certificate of merger with respect to the first merger is filed with the Delaware Secretary of State (or at such later time as Expedia Group and Liberty Expedia agree upon and state in the certificate of merger), which is referred to as the effective time, upon the terms and subject to the conditions set forth in the merger agreement, each share of Liberty Expedia common stock issued and outstanding immediately

prior to the effective time (other than shares held by Liberty Expedia as treasury stock or held directly by Expedia Group, which are collectively referred to herein as excluded shares) will be converted into the right to receive the merger consideration, which is 0.36 of a share of Expedia Group common stock, with cash (without interest) paid in lieu of any fractional shares of Expedia Group common stock. The fraction of a share of Expedia Group common stock into which each share of Liberty Expedia common stock (other than excluded shares) will be converted is referred to as the exchange ratio.

All fractional shares of Expedia Group common stock that would otherwise be issued to a Liberty Expedia stockholder of record as part of the merger consideration will be aggregated and the shares resulting from such aggregation will be sold at prevailing market prices on behalf of Liberty Expedia stockholders who otherwise would have been entitled to receive such fractional shares. Each such Liberty Expedia stockholder will be paid, in lieu of such fractional share of Expedia Group common stock, an amount in cash, without interest, in proportion to the stockholder’s corresponding pro rata portion.

Treatment of Equity Awards

At the effective time:

See “The Merger Agreement—Treatment of Equity Awards” beginning on page 64 of this proxy statement/prospectus.

Treatment of Existing Debt

See “The Transaction—Treatment of Existing Debt” beginning on page 59 of this proxy statement/prospectus.

Recommendation of the Liberty Expedia Board of Directors

The Liberty Expedia Board, based on the unanimous recommendation of the Liberty Expedia transaction committee, unanimously determined that the merger agreement and the other transaction documents, and the transactions contemplated thereby (including the transactions contemplated by the voting agreement and the new governance agreement) are advisable and fair to, and in the best interests of, Liberty Expedia and its stockholders, and approved and declared advisable the merger agreement and the other transaction documents, and the transactions contemplated thereby (including the transactions contemplated by the voting agreement and the new governance agreement).

Opinion of Liberty Expedia’s Financial Advisor

At the meeting of the Liberty Expedia transaction committee on April 15, 2019 held to evaluate the proposed acquisition of Liberty Expedia by Expedia Group pursuant to the merger agreement and the other transactions contemplated thereby, Moelis & Company LLC, which is referred to as Moelis, rendered to the Liberty Expedia transaction committee an oral opinion, which was subsequently confirmed by delivery of a written opinion, dated April 15, 2019, addressed to the Liberty Expedia Board that, subject to the assumptions, limitations, qualifications and other matters stated in its written opinion, as of the date of the opinion, the exchange ratio of 0.36 of a share of Expedia Group common stock per share of Liberty Expedia common stock in the first merger, was fair from a financial point of view to the holders of Liberty Expedia common stock, other than John C. Malone, Leslie Malone and Barry Diller and their respective affiliates, who are collectively referred to as the excluded holders.

The full text of Moelis’ written opinion, dated April 15, 2019, which sets forth the assumptions, limitations, qualifications and other matters considered in connection with the opinion, is attached as Annex J to this proxy statement/prospectus and is incorporated by reference into this proxy statement/prospectus.

Moelis’ opinion is limited solely to the fairness, from a financial point of view, of the exchange ratio in the first merger to the holders of Liberty Expedia common stock, other than the excluded holders, and does not address Liberty Expedia’s underlying business decision to effect the proposed acquisition or the relative merits of the proposed acquisition as compared to any alternative business strategies or transactions that might be available to Liberty Expedia. Moelis’ opinion does not constitute a recommendation as to how any holder of securities should vote or act with respect to the proposed acquisition or any other matter. Moelis’ opinion was approved by a Moelis fairness opinion committee.

For a description of the opinion that the Liberty Expedia transaction committee and the Liberty Expedia Board received from Moelis, see “The Transaction—Opinion of Liberty Expedia’s Financial Advisor” beginning on page 50.

Interests of Liberty Expedia’s Directors and Executive Officers in the Transaction

For more information regarding these interests, see “The Transaction—Interests of Directors and Executive Officers of Liberty Expedia in the Transaction” on page 56.

See “The Transaction—Regulatory Approvals” beginning on page 59.

Conditions to Completion of the Transaction

In addition to the approval of the merger proposal by the Liberty Expedia stockholders and any required approvals under the HSR Act, each party’s obligation to complete the mergers is also subject to the satisfaction or waiver of certain other conditions, including, among other things, (1) the effectiveness under the Securities Act of the registration statement on Form S-4 of which this proxy statement/prospectus forms a part, (2) the approval for listing on NASDAQ of the shares of Expedia Group common stock to be issued in connection with the mergers, subject to official issuance, (3) the absence of any order or law that has the effect of enjoining or otherwise prohibiting the closing of the mergers or any of the other transactions contemplated by the merger agreement and related transaction documents, and (4) the delivery of an opinion by Skadden to Liberty Expedia to the effect that, subject to the limitations and assumptions therein, the transactions contemplated by the merger agreement will not impact the tax treatment of the split-off.

In addition, Expedia Group’s obligation to close the mergers is subject to the completion of the exchange, except under limited circumstances where the sole cause of the failure of the exchange to close is Mr. Diller’s failure to close. Expedia Group may not waive this condition without Mr. Diller’s prior consent.

See “The Merger Agreement—Conditions to the Mergers” beginning on page 74.

Timing of the Transaction

The mergers are expected to be completed in the third quarter of 2019. Neither Expedia Group nor Liberty Expedia can predict, however, the actual date on which the mergers will be completed because it is subject to conditions beyond each company’s control.

No Solicitation

As more fully described in this proxy statement/prospectus and in the merger agreement, Liberty Expedia has agreed to non-solicitation obligations with respect to any third-party acquisition proposals (including provisions restricting its ability to provide confidential information to any third party), and has agreed to certain restrictions on its and its representatives’ ability to respond to any such proposals. The Liberty Expedia Board has agreed to recommend that the Liberty Expedia stockholders vote in favor of the merger proposal, subject to the right to change its recommendation in response to a company superior proposal or an intervening event (each as described below in this proxy statement/prospectus), in each case if the Liberty Expedia Board determines in good faith after consultation with its outside counsel and financial advisor that a failure to change its recommendation would be inconsistent with its fiduciary duties under applicable law.

For a more complete description of the limitations on solicitation of acquisition proposals from third parties and the ability of the Liberty Expedia Board to change its recommendation in favor of the merger proposal, see “The Merger Agreement—Covenants and Agreements—No Solicitation” beginning on page 69.

For a more complete description of each party’s termination rights and related termination fee obligations, see “The Merger Agreement—Termination” beginning on page 75 and “The Merger Agreement—Termination Fee” beginning on page 76.

No Appraisal Rights

Under the DGCL, Liberty Expedia stockholders do not have appraisal rights in connection with the transaction. See “Appraisal Rights” beginning on page 131.

Material U.S. Federal Income Tax Consequences

It is intended that the mergers, taken together, will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. It is a condition to each of Expedia Group’s and Liberty Expedia’s obligation to complete the mergers that it receive a reorganization tax opinion from its counsel. Accordingly, on the basis of such opinions, a U.S. holder (as defined under “The Transaction—Material U.S. Federal Income Tax Consequences”) of Liberty Expedia common stock will not recognize gain or loss for U.S. federal income tax purposes as a result of the exchange of Liberty Expedia common stock for Expedia Group common stock pursuant to the mergers, except with respect to any cash received in lieu of fractional shares of Expedia Group common stock.

Holders of Liberty Expedia common stock should read the section entitled “The Transaction—Material U.S. Federal Income Tax Consequences” for a more complete discussion of the U.S. federal income tax consequences of the mergers. This proxy statement/prospectus contains a general discussion of the U.S. federal income tax consequences of the mergers. Tax matters can be complicated, and the tax consequences to a particular holder will depend on such holder’s particular facts and circumstances. This proxy statement/prospectus does not address any non-U.S. tax consequences, nor does it pertain to state or local income or other tax consequences of the mergers. Liberty Expedia stockholders should consult their own tax advisors to determine the specific consequences to them of receiving Expedia Group common stock pursuant to the mergers, as well as the specific tax consequences to them under any state, local or non-U.S. income or other tax laws.

Accounting Treatment

Expedia Group prepares its financial statements in accordance with accounting principles generally accepted in the United States, which is referred to as GAAP. Expedia Group will account for the acquisition of Liberty Expedia as a business combination and the repurchase of Expedia Group shares held by Liberty Expedia as a transaction separate from the business combination. Therefore, Expedia Group will account for the acquired Liberty Expedia assets and liabilities as a business combination at their respective acquisition date fair values, and the acquisition of Expedia Group shares held by Liberty Expedia as a share repurchase.

The following table presents selected historical consolidated financial data for Expedia Group as of and for the fiscal years ended December 31, 2018, 2017, 2016, 2015 and 2014. The statement of operations data and cash flow data for the fiscal years ended December 31, 2018, 2017 and 2016 and the balance sheet data as of December 31, 2018 and 2017 have been obtained from Expedia Group’s audited consolidated financial statements incorporated by reference in Expedia Group’s Annual Report on Form 10-K, as amended, for the fiscal year ended December 31, 2018, which is incorporated by reference into this proxy statement/prospectus. The statement of operations data for the fiscal years ended December 31, 2015 and 2014 and the balance sheet data as of December 31, 2016, 2015 and 2014 have been derived from Expedia Group’s audited consolidated financial statements for such years, which have not been incorporated by reference into this proxy statement/prospectus.

The information set forth below is not necessarily indicative of future results and should be read together with the other information contained in Expedia Group’s Annual Report on Form 10-K, as amended, for the fiscal year ended December 31, 2018, including the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and related notes therein. See the section entitled “Where You Can Find More Information” beginning on page 134.

Free Cash Flow is defined as net cash flow provided by operating activities less capital expenditures. Expedia Group management believes Free Cash Flow is useful to investors because it represents the operating cash flow that our operating businesses generate, less capital expenditures but before taking into account other cash movements that are not directly tied to the core operations of our businesses, such as financing activities, foreign exchange or certain investing activities. Free Cash Flow has certain limitations in that it does not represent the total increase or decrease in the cash balance for the period, nor does it represent the residual cash flow for discretionary expenditures. Therefore, it is important to evaluate Free Cash Flow along with the consolidated statements of cash flows. Following is a reconciliation from Net Cash Provided by Operating Activities to Free Cash Flow:

SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA OF LIBERTY EXPEDIA

The following tables present selected historical financial statement information relating to Liberty Expedia’s financial condition and results of operations for the past five years. Certain prior period amounts have been reclassified for comparability with the current year presentation. The following data should be read in conjunction with Liberty Expedia’s consolidated financial statements contained in its Annual Report on Form 10-K, as amended, for the year ended December 31, 2018, which is incorporated by reference into this proxy statement/prospectus. See the section entitled “Where You Can Find More Information” beginning on page 134.

COMPARATIVE HISTORICAL AND UNAUDITED PRO FORMA PER SHARE DATA

The following table summarizes unaudited per share data (1) for Expedia Group and Liberty Expedia on a historical basis, (2) for Expedia Group on a pro forma combined basis giving effect to the exchange and the mergers (but not the purchase/exchange right) and (3) on a pro forma combined equivalent basis calculated by multiplying the pro forma combined data by the exchange ratio of 0.36 as described in the section entitled “The Merger Agreement—Merger Consideration” beginning on page 63.

We assume that the exchange and the mergers occurred as of the beginning of the fiscal year or period presented (or in the case of book value per share, as of December 31, 2018). The information in the table is based on, and should be read together with, the historical financial information of Expedia Group and Liberty Expedia, which is incorporated by reference in this proxy statement/prospectus and the financial information contained under “Selected Historical Financial Data—Selected Historical Consolidated Financial Data of Expedia Group” and “Selected Historical Financial Data—Selected Historical Consolidated Financial Data of Liberty Expedia” beginning on page 21 and page 23, respectively. See the section entitled “Where You Can Find More Information” beginning on page 134.

The unaudited pro forma combined information gives effect to the mergers accounted for as described in the section entitled “The Transaction—Accounting Treatment” beginning on page 61. The pro forma calculations reflect that each outstanding share of Liberty Expedia Series A common stock and Liberty Expedia Series B common stock outstanding immediately prior to the effective time will be converted into the right to receive 0.36 of a share of Expedia Group common stock (including shares of Liberty Expedia common stock subject to Liberty Expedia stock options, restricted stock units and awards) as well as the share repurchase by Expedia Group of its shares held by Liberty Expedia immediately prior to the effective time, resulting in a net estimated reduction in outstanding shares of Expedia Group common stock and Expedia Group Class B common stock of 3.1 million shares. The pro forma calculations also reflect the acquisition of the assets and liabilities of Liberty Expedia at estimated fair values. The unaudited pro forma combined per share data is presented for illustrative purposes only and is not necessarily indicative of actual or future financial position or results of operations that would have been realized if the exchange and the mergers had been completed as of the dates indicated or will be realized upon the completion of the exchange and the mergers. The summary pro forma information is preliminary, based on initial estimates of the fair value of assets acquired (including intangible assets) and liabilities assumed, and is subject to change as more information regarding the fair values are obtained, which changes could be materially different than the initial estimates.

Expedia Group declared and paid dividends during the periods presented. For more information on dividends of Expedia Group, see the section entitled “Comparative Per Share Market Price and Dividend Information” beginning on page 25.

COMPARATIVE PER SHARE MARKET PRICE AND DIVIDEND INFORMATION

Expedia Group Market and Dividend Information

Expedia Group common stock is listed on NASDAQ under the symbol “EXPE.” Expedia Group Class B common stock is not listed and there is no established public trading market. As of January 25, 2019, there were approximately 2,014 holders of record of Expedia Group common stock and the closing price of Expedia Group common stock as of April 29, 2019 was $129.98 on NASDAQ. As of January 25, 2019, all Expedia Group Class B common stock was held by a subsidiary of Liberty Expedia.

Most recently, Expedia Group declared a quarterly dividend of $0.32 per Expedia Group share, which was paid on March 27, 2019 to holders of record as of the close of business on March 7, 2019. In 2018 and 2017, Expedia Group’s Executive Committee, acting on behalf of the Expedia Group Board, declared the following dividends:

The declaration of future dividends will be at the discretion of the Expedia Group Board, and will be determined after consideration of various factors, including earnings, cash requirements, the financial condition of Expedia Group and other factors deemed relevant by the Expedia Group Board. Under the merger agreement, prior to the completion of the mergers, Expedia Group may continue to pay its regular quarterly cash dividends in the ordinary course consistent with past practice (subject to Expedia Group’s right to increase its quarterly cash dividends resulting in up to $125 million of aggregate dividends per quarter).

Liberty Expedia Market and Dividend Information

Liberty Expedia Series A common stock and Liberty Expedia Series B common stock are listed on NASDAQ under the symbols “LEXEA” and “LEXEB,” respectively. The following table sets forth the high and low prices per share for Liberty Expedia Series B common stock for the periods indicated, each rounded to the nearest whole cent. Although Liberty Expedia Series B common stock is traded on NASDAQ, an established public trading market does not exist for the stock, as it is not actively traded. Liberty Expedia’s fiscal year ends on December 31.

Liberty Expedia has not paid any cash dividends on its common stock, and has no present intention of so doing. Payment of cash dividends, if any, in the future will be determined by the Liberty Expedia Board in light of Liberty Expedia’s earnings, financial condition and other relevant considerations.

Comparison of Expedia Group and Liberty Expedia Market Prices and Implied Value of Merger Consideration

The following table sets forth the closing sale price per share of Expedia Group common stock, Liberty Expedia Series A common stock and Liberty Expedia Series B common stock as reported on NASDAQ as of February 1, 2019, the last trading day prior to the initial public announcement of negotiations relating to the transaction; as of April 15, 2019, the last trading day prior to the public announcement of the entry into the merger agreement; and as of April 29, 2019, the last practicable trading day before the filing of this proxy statement/prospectus with the SEC. The table also shows the estimated implied value of the per share consideration proposed for each share of Liberty Expedia Series A common stock and Liberty Expedia Series B common stock as of the same three days. This implied value was calculated by multiplying the closing prices of shares of Expedia Group common stock on those dates by the exchange ratio of 0.36. The market prices of Expedia Group common stock, Liberty Expedia Series A common stock and Liberty Expedia Series B common stock have fluctuated since the date of the announcement of the merger agreement and will continue to fluctuate from the date of this proxy statement/prospectus to the date of the special meeting and the date the first merger is completed and thereafter (in the case of Expedia Group common stock).

No assurance can be given concerning the market prices of Expedia Group common stock, Liberty Expedia Series A common stock or Liberty Expedia Series B common stock before completion of the mergers or Expedia Group common stock after completion of the mergers. Because the merger consideration is payable in a fixed number of shares of Expedia Group common stock, the market price of Expedia Group common stock (and therefore the value of the merger consideration) when received by Liberty Expedia stockholders after the completion of the mergers could be greater than, less than or the same as shown in the table above. Accordingly, Liberty Expedia stockholders are advised to obtain current market quotations for Expedia Group common stock and Liberty Expedia Series A common stock or Liberty Expedia Series B common stock, as applicable, in deciding whether to vote in favor of the merger proposal.

RISK FACTORS

In addition to the other information included and incorporated by reference into this proxy statement/prospectus, including, among other things, the matters addressed in the section entitled “Cautionary Note Regarding Forward-Looking Statements” beginning on page 34, Liberty Expedia stockholders should carefully consider the following risk factors before deciding whether to vote in favor of the merger proposal. In addition, you should read and consider the risks associated with each of the businesses of Expedia Group and Liberty Expedia because these risks will relate to the combined company following the completion of the transaction. Descriptions of some of these risks can be found in the Expedia Group Annual Report on Form 10-K for the fiscal year ended December 31, 2018, as amended, and the Liberty Expedia Annual Report on Form 10-K for the fiscal year ended December 31, 2018, as amended, as such risks may be updated or supplemented in each company’s subsequently filed Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, which are incorporated by reference into this proxy statement/prospectus. You should also consider the other information in this document and the other documents incorporated by reference into this proxy statement/prospectus. See the section entitled “Where You Can Find More Information” beginning on page 134.

Risks Related to the Transaction

The transaction is subject to conditions, some or all of which may not be satisfied, or completed on a timely basis, if at all. Failure to complete the transaction could have material adverse effects on Liberty Expedia.

The completion of the transaction is subject to a number of conditions, including, among other things, receipt of the Liberty Expedia stockholder approval. See the section entitled “The Merger Agreement—Conditions to the Mergers,” beginning on page 74, for a more detailed discussion. The failure to satisfy all of the required conditions could delay the completion of the transaction for a significant period of time or prevent it from occurring at all. Any delay in completing the transaction could cause Expedia Group not to realize some or all of the benefits, or realize them on a different timeline than expected, that Expedia Group expects to achieve if the transaction is successfully completed within the expected timeframe. There can be no assurance that the conditions to the closing of the mergers will be satisfied or (to the extent permitted by law) waived or that the mergers will be completed. Also, subject to limited exceptions, either Expedia Group or Liberty Expedia may terminate the merger agreement if the mergers have not been completed by on or before October 15, 2019, subject to possible extension as set forth in the merger agreement. See “The Merger Agreement—Termination” beginning on page 75.

If the transaction is not completed, Liberty Expedia may be materially adversely affected and, without realizing any of the benefits of having completed the transaction, Liberty Expedia will be subject to a number of risks, including the following:

In addition, if the transaction is not completed, Liberty Expedia could be subject to litigation related to any failure to complete the merger or related to any enforcement proceeding commenced against Liberty Expedia to perform its obligations under the merger agreement. Any of these risks could materially and adversely impact Liberty Expedia’s financial condition, financial results and stock price.

Similarly, delays in the completion of the transaction could, among other things, result in additional transaction costs or other negative effects associated with uncertainty about completion of the transaction and could materially and adversely impact Expedia Group’s ongoing business, financial condition, financial results and stock price following the completion of the transaction.

The merger agreement contains provisions that limit Liberty Expedia’s ability to pursue alternatives to the transaction, could discourage a potential competing acquiror of Liberty Expedia from making a favorable alternative company transaction proposal and, in specified circumstances, could require Liberty Expedia to pay a substantial termination fee to Expedia Group.

The merger agreement contains provisions that make it more difficult for Liberty Expedia to be acquired by any person other than Expedia Group. The merger agreement contains certain provisions that restrict Liberty Expedia’s ability to, among other things, solicit, initiate, knowingly facilitate, knowingly induce, knowingly encourage, or enter into or continue or otherwise participate in any discussions relating to, or approve or recommend, any third-party acquisition proposal. Further, even if the Liberty Expedia Board withdraws or qualifies its recommendation with respect to the approval of the transaction proposal, unless the merger agreement is terminated in accordance with its terms, Liberty Expedia will still be required to submit the merger proposal to a vote at the special meeting of Liberty Expedia stockholders. In addition, following receipt by Liberty Expedia of any third-party acquisition proposal that constitutes a “superior proposal,” Expedia Group will have an opportunity to offer to modify the terms of the merger agreement before the Liberty Expedia Board may withdraw or qualify its recommendation with respect to the merger proposal in favor of such superior proposal, as described further under “The Merger Agreement—Covenants and Agreements—No Solicitation” beginning on page 69.

In some circumstances, upon termination of the merger agreement, Liberty Expedia would be required to pay a termination fee of $72 million to Expedia Group. For further discussion, see the section entitled “The Merger Agreement—Termination;—Effect of Termination;—Termination Fee” beginning on page 76.

These provisions could discourage a potential third-party acquiror or merger partner that might have an interest in acquiring all or a significant portion of Liberty Expedia or pursuing an alternative company transaction from considering or proposing such a transaction, even if it were prepared to pay consideration with a higher per share value than the value proposed to be received in the merger. In particular, the termination fee, if applicable, would be substantial, and could result in a potential third-party acquiror or merger partner proposing to pay a lower price to the Liberty Expedia stockholders than it might otherwise have proposed to pay absent such a fee.

If the merger agreement is terminated and Liberty Expedia determines to seek another business combination, Liberty Expedia may not be able to negotiate a transaction with another party on terms comparable to, or better than, the terms of the merger.

The value of the merger consideration is subject to changes based on fluctuations in the value of Expedia Group common stock, and Liberty Expedia stockholders may receive stock consideration with a value that, at the time received, is less than $46.79 per share of Liberty Expedia Series A or Series B common stock, the implied value of 0.36 of a share of Expedia Group common stock based on the closing price of Expedia Group common stock on April 29, 2019, the last practicable trading day before the filing of this proxy statement/prospectus with the SEC.

The market value of Expedia Group common stock will fluctuate during the period before the date of the special meeting and during the period before the time Liberty Expedia stockholders receive merger consideration in the form of Expedia Group common stock, as well as thereafter. Accordingly, at the time of the special meeting, Liberty Expedia stockholders will not be able to determine the market value of the per share merger consideration they would receive upon completion of the mergers.

Upon completion of the mergers, each issued and outstanding share of Liberty Expedia Series A and Liberty Expedia Series B common stock (other than excluded shares) will be converted into the right to receive the

merger consideration, which is equal to 0.36 of a share of Expedia Group common stock, with cash (without interest) paid in lieu of any fractional shares of Expedia Group common stock. Accordingly, the value of Expedia Group common stock delivered to Liberty Expedia stockholders will depend on the Expedia Group stock price, and the value of the shares of Expedia Group common stock delivered for each such share of Liberty Expedia Series A and Liberty Expedia Series B common stock may be greater than, less than or equal to $46.79, the implied value of 0.36 of a share of Expedia Group common stock based on the closing price of Expedia Group common stock on April 29, 2019, the last practicable trading day before the filing of this proxy statement/prospectus with the SEC.

It is impossible to accurately predict the market price of Expedia Group common stock at the completion of the mergers and, therefore, impossible to accurately predict the value of the shares of Expedia Group common stock that Liberty Expedia stockholders will receive. The market price for Expedia Group common stock may fluctuate both prior to the completion of the transaction and thereafter for a variety of reasons, including, among others, general market and economic conditions, the demand for Expedia Group’s products and services, changes in laws and regulations, other changes in Expedia Group’s businesses, operations, prospects and financial results of operations, market assessments of the likelihood that the mergers will be completed, and the expected timing of the mergers. Many of these factors are beyond Expedia Group’s and Liberty Expedia’s control. You should obtain current market quotations for shares of Expedia Group common stock.

Each party is subject to contractual restrictions while the mergers are pending, which could adversely affect each party’s business and operations.

Under the terms of the merger agreement, Liberty Expedia is subject to certain restrictions on the conduct of its business prior to completing the transaction which may adversely affect its and its subsidiaries’ ability to execute certain of its business strategies, maintain customers, or manage risks associated with its business, operations, technology, infrastructure or compliance functions, including the ability in certain cases to enter into or amend contracts, acquire or dispose of assets, incur indebtedness, incur capital expenditures, engage with regulators, settle actual or potential claims, or (in certain instances) communicate with its customers, employees and/or vendors. Such limitations could adversely affect Liberty Expedia prior to the completion of the transaction.

Under the terms of the merger agreement, Expedia Group is subject to a more limited set of restrictions on the conduct of its business prior to completing the mergers which may adversely affect its ability to execute certain of its business strategies, including the ability in certain cases to amend its organizational documents, pay extraordinary dividends or distributions or repurchase shares of Expedia Group common stock. Such limitations could adversely affect Expedia Group prior to the completion of the transaction.

Each of the risks described above may be exacerbated by delays or other adverse developments with respect to the completion of the transaction. For further discussion, see the section entitled “The Merger Agreement—Covenants and Agreements—Conduct of Business of Liberty Expedia;—Conduct of Business of Expedia Group” beginning on page 66.

Liberty Expedia’s executive officers and directors have interests in the transaction that may be different from, or in addition to, Liberty Expedia stockholders’ interests.

When considering the recommendation of the Liberty Expedia Board, based on the unanimous recommendation of the Liberty Expedia transaction committee, that Liberty Expedia stockholders approve the adoption of the merger agreement, the Liberty Expedia stockholders should be aware that directors and executive officers of Liberty Expedia have certain interests in the transaction that may be different from, or be in addition to, the interests of Liberty Expedia stockholders, including, among other things, the accelerated vesting of equity awards and the preservation of indemnification and insurance protections for service as directors and executive officers of Liberty Expedia and its subsidiaries. See the section entitled “The Transaction—Interests of Directors and Executive Officers of Liberty Expedia in the Transaction” beginning on page 56 for a more detailed description of these interests.

The transaction could result in a significant liability to Liberty Expedia and Expedia Group if it causes the 2016 split-off of Liberty Expedia by Qurate Retail to fail to qualify as a tax-free distribution under applicable tax laws.

In connection with the signing of the merger agreement, Liberty Expedia received an opinion from Skadden to the effect that, subject to the limitations and assumptions set forth therein, the transaction will not cause the

split-off to fail to qualify as a tax-free distribution under Sections 355 and 361 of the Code, to Qurate Retail, Liberty Expedia, their respective subsidiaries and the former holders of Liberty Ventures common stock (except with respect to any cash received in lieu of fractional shares), which is referred to as the signing split-off tax opinion. It is a condition to each party’s obligation to complete the mergers that Skadden deliver to Liberty Expedia an opinion to the same effect as the signing split-off tax opinion and subject to similar limitations and assumptions, immediately prior to the consummation of the mergers, which is referred to as the closing split-off tax opinion. The signing split-off tax opinion relied on, and the closing split-off tax opinion will rely on, certain representations and assumptions, including those contained in representation letters from each of Qurate Retail, Liberty Expedia, Expedia Group, Mr. Malone and Mr. Diller. If any of the factual representations in any of these representation letters, or any of the assumptions in the signing split-off tax opinion or the closing split-off tax opinion is untrue or incomplete, the signing split-off tax opinion or the closing split-off tax opinion may not be valid. Moreover, an opinion of counsel is not binding on the IRS or the courts. As a result, the conclusions expressed in the signing split-off tax opinion and the closing split-off tax opinion could be challenged by the IRS, and a court may sustain such a challenge. If, for any reason, it is subsequently determined that the split-off does not qualify for tax-free treatment under Sections 355 and 361 of the Code, Liberty Expedia and Expedia Group could be required, in certain circumstances, to indemnify Qurate Retail, its subsidiaries and certain related persons for significant tax liabilities resulting from the split-off.

As described in Liberty Expedia’s registration statement on Form S-1 (File No. 333-210377) initially filed with the SEC on March 24, 2016, as amended, if the split-off does not qualify under Section 355, Section 368(a)(1)(D) and related provisions of the Code, Qurate Retail would generally be subject to tax as if it sold the shares of Liberty Expedia common stock distributed in the split-off in a taxable transaction. In such a circumstance, Qurate Retail would recognize taxable gain in an amount equal to the excess of (1) the total fair market value of the shares of Liberty Expedia common stock distributed in the split-off over (2) Qurate Retail’s aggregate tax basis in such shares of Liberty Expedia common stock. Pursuant to the tax sharing agreement by and between Qurate Retail and Liberty Expedia and the joinder to the tax sharing agreement by and among Qurate Retail, Liberty Expedia and Expedia Group, in certain circumstances, Liberty Expedia and Expedia Group will be required to jointly and severally indemnify Qurate Retail and its subsidiaries for any taxes or losses resulting from the failure of the split-off to qualify as a tax-free transaction under Section 355, Section 368(a)(1)(D) and related provisions of the Code, including to the extent that such taxes or losses (1) result primarily from, individually or in the aggregate, the breach of certain covenants made by Liberty Expedia (applicable to actions or failures to act by Liberty Expedia and its subsidiaries following the completion of the split-off), (2) result from the application of Section 355(e) of the Code to the split-off as a result of the treatment of the split-off as part of a plan (or series of related transactions) pursuant to which one or more persons acquire, directly or indirectly, a 50-percent or greater interest (measured by either vote or value) in the stock of Liberty Expedia (or any successor corporation) or (3) result primarily from, individually or in the aggregate, the breach by Expedia Group of certain covenants under the tax sharing agreement following the completion of the mergers. Any such indemnity obligation could be material. See “Additional Transaction Agreements—Joinder Agreements” beginning on page 93.

Risks Related to Expedia Group and the Combined Company after Completion of the Transaction

Expedia Group may fail to realize all of the anticipated benefits of the transaction or those benefits may take longer to realize than expected.

The full benefits of the transaction may not be realized as expected or may not be achieved within the anticipated time frame, or at all. Failure to achieve the anticipated benefits of the transaction could adversely affect Expedia Group’s results of operations or cash flows, cause dilution to the earnings per share of Expedia Group, decrease or delay the expected accretive effect of the transaction, and negatively impact the price of Expedia Group common stock. In addition, there may be liabilities that Expedia Group underestimated or did not discover in the course of performing its due diligence investigation of Liberty Expedia.

Liberty Expedia stockholders will have a reduced ownership and voting interest after the transaction and will exercise less influence over the policies of Expedia Group following the mergers than they now have on the policies of Liberty Expedia.

Liberty Expedia stockholders presently have the right to vote in the election of the Liberty Expedia Board and on other matters affecting Liberty Expedia. Upon the completion of the mergers, each Liberty Expedia stockholder will be a stockholder of Expedia Group with a percentage ownership of Expedia Group (assuming no overlap between Expedia Group and Liberty Expedia stockholders) that is smaller than such stockholder’s current

percentage ownership of Liberty Expedia. Immediately after the transaction is completed, it is expected that current Expedia Group stockholders will own approximately 86% of Expedia Group’s capital stock outstanding (representing 89% of the voting power) and current Liberty Expedia stockholders will own approximately 14% of Expedia Group’s capital stock outstanding (representing 11% of the voting power), and assuming no overlap between Expedia Group and Liberty Expedia stockholders.

The Expedia Group common stock to be received by Liberty Expedia stockholders upon completion of the transaction will have different rights from shares of Liberty Expedia common stock.

Upon completion of the mergers, Liberty Expedia stockholders will no longer be stockholders of Liberty Expedia, but will instead become stockholders of Expedia Group and their rights as Expedia Group stockholders will be governed by the terms of Expedia Group’s certificate of incorporation and bylaws. The terms of Expedia Group’s certificate of incorporation and bylaws are in some respects materially different than the terms of Liberty Expedia’s certificate of incorporation and bylaws, which currently govern the rights of Liberty Expedia stockholders.

Each holder of Liberty Expedia Series B common stock is currently entitled to vote ten votes for each share of Liberty Expedia Series B common stock held by such stockholder in the election of the Liberty Expedia Board and on other matters affecting Liberty Expedia. The shares of Expedia Group common stock that holders of Liberty Expedia Series B common stock would receive as merger consideration would entitle such holders to vote only one vote for each share of Expedia Group common stock held by such holder in the election of the Expedia Group Board and on other matters affecting Expedia Group.

Upon the completion of the transaction, former Liberty Expedia stockholders (in the aggregate) are expected to own shares of Expedia Group common stock representing approximately 14% of the total number of outstanding shares of Expedia Group common stock and Expedia Group Class B common stock, or 11% of the total voting power of outstanding shares of Expedia Group common stock and Expedia Group Class B common stock, based on approximately 140 million shares of Expedia Group common stock and approximately 5.7 million shares of Expedia Group Class B common stock currently expected to be outstanding at the closing of the mergers.

For a more complete description of the different rights associated with shares of Liberty Expedia common stock and shares of Expedia Group common stock, see “Comparison of Stockholder Rights” beginning on page 121.

The market price of Expedia Group common stock may decline as a result of the transaction.

The market price of Expedia Group common stock may decline as a result of the transaction if, among other things, the transaction costs are greater than expected, Expedia Group does not achieve the perceived benefits of the transaction as rapidly or to the extent anticipated by financial or industry analysts or the effect of the transaction on Expedia Group’s financial position, results of operations or cash flows is not consistent with the expectations of financial or industry analysts. Any of these events may make it more difficult for Expedia Group to sell equity or equity-related securities and have an adverse impact on the price of Expedia Group common stock.

Expedia Group and Liberty Expedia will incur direct and indirect costs as a result of the mergers.

Expedia Group and Liberty Expedia will incur substantial expenses in connection with and as a result of completing the mergers, including advisory, legal and other transaction costs, and, following the completion of the mergers, Expedia Group expects to incur additional expenses in connection with combining the companies and integrating the Bodybuilding business. A majority of these costs have already been incurred or will be incurred regardless of whether the mergers are completed. Factors beyond Liberty Expedia’s and Expedia Group’s control could affect the total amount or timing of these expenses, many of which, by their nature, are difficult to estimate accurately.

Following the completion of the mergers, it is expected that Mr. Diller will own approximately 29% of the outstanding voting power of Expedia Group, and have the right to purchase or exchange for additional shares of Expedia Group Class B common stock.

Pursuant to the Diller proxy granted by Liberty Expedia to Mr. Diller under the existing stockholders agreement, Mr. Diller generally has the right to vote the shares of Expedia Group common stock and Expedia Group Class B common stock held by Liberty Expedia and its subsidiaries, which shares represent approximately 53% of the total voting power of Expedia Group, based on a total of 136,007,689 shares of Expedia Group common stock and 12,799,999 shares of Expedia Group Class B common stock outstanding as of April 19, 2019. Pursuant to the stockholders agreement termination agreement, following the completion of the mergers, the existing stockholders agreement and, therefore, the Diller proxy, will be terminated.

In addition, under the existing governance agreement, Mr. Diller generally has the right, along with Liberty Expedia, to consent to certain matters in the event that Expedia Group incurs debt such that Expedia Group’s ratio of total debt to EBITDA, as defined in the existing governance agreement, equals or exceeds 8:1 over a continuous 12-month period.

Immediately prior to the completion of the mergers, Mr. Diller and, if the Family Foundation so elects, the Family Foundation, are expected to exchange approximately 5.7 million shares of Expedia Group common stock for an equal number of shares of Expedia Group Class B common stock currently held by Liberty Expedia. The original shares would represent approximately 29% of the total outstanding voting power of Expedia Group, based on approximately 140 million shares of Expedia Group common stock and approximately 5.7 million shares of Expedia Group Class B common stock currently expected to be outstanding at the closing of the mergers. The original shares are freely transferrable and may, at a future time, be held by another stockholder.

For the nine months following the completion of the mergers, under the new governance agreement, Mr. Diller will have the right to purchase the remaining approximately 7.1 million additional shares of Expedia Class B common stock currently held by Liberty Expedia. Assuming the exercise of such right in full by Mr. Diller, Mr. Diller could beneficially own original shares and additional shares in an amount collectively representing up to approximately 49% of the total voting power of all outstanding shares of Expedia Group common stock and Expedia Group Class B common stock, assuming a total of approximately 133 million shares of Expedia Group common stock and 12,799,999 shares of Expedia Group Class B common stock outstanding immediately following the exercise of such right if Mr. Diller exercises his purchase/exchange right solely by exchanging shares of Expedia Group common stock acquired in the open market (or otherwise, other than from Expedia Group). If Mr. Diller acquires the additional shares through cash purchases directly from Expedia Group (or its wholly owned subsidiary), the original shares and additional shares would collectively represent approximately 48% of the total voting power of all outstanding shares of Expedia Group common stock and Expedia Group Class B common stock.

In connection with the transaction, Mr. Diller has agreed that the rights provided for in the exchange agreement and the new governance agreement, which were negotiated by a special committee of the Expedia Group Board consisting solely of independent and disinterested directors, each of whom had been elected by the holders of Expedia Group common stock voting together as a class (without the vote of the Expedia Group Class B common stock), which is referred to as the Expedia Group special committee, are deemed to be in recognition and in lieu of Mr. Diller’s existing rights under the existing stockholders agreement and the existing governance agreement.

Although it is expected that following the completion of the mergers, Expedia Group will no longer be a controlled company under the NASDAQ rules, in the future, Mr. Diller’s ownership percentage in Expedia Group could increase if he buys additional shares of Expedia Group common stock in open market purchases or otherwise, or if Expedia Group repurchases shares of its common stock. However, upon transfer, any additional shares will automatically convert into Expedia Group common stock unless Mr. Diller retains sole voting control over such transferred additional shares. Additionally, all additional shares will be automatically converted into shares of Expedia Group common stock immediately following the earliest of (a) Mr. Diller’s death or disability, (b) such time as Mr. Diller no longer serves as chairman or senior executive of Expedia Group, other than as a result of his removal (other than for “cause” as defined in the new governance agreement), or failure to be nominated or elected when he is willing to serve in such position, and (c) aggregate transfers by Mr. Diller (or certain limited permitted transferees of Mr. Diller) of original shares exceeding 5% of the outstanding voting power of Expedia Group. Therefore, while it is possible that Mr. Diller may at some point in the future

beneficially own more than 50% of the outstanding voting power of Expedia Group, the provisions of the new governance agreement provide that following one of the triggers described above, the maximum number of shares of Expedia Group Class B common stock outstanding that were initially acquired by Mr. Diller in the exchange or pursuant to the purchase/exchange right will not exceed approximately 5.7 million shares of Expedia Group Class B common stock. Moreover, under the new governance agreement, subject to limited exception, no current or future holder of original shares or additional shares may participate in, or vote in favor of, or tender shares into, any change of control transaction involving at least 50% of the outstanding shares or voting power of capital stock of Expedia Group, unless such transaction provides for the same per share consideration and mix of consideration (or election right) and the same participation rights for shares of Expedia Group Class B common stock and shares of Expedia Group common stock. The transfer restrictions and restrictions with respect to future change in control transactions do not exist in the existing governance agreement. Additionally, the new governance agreement does not provide Mr. Diller with any consent rights over corporate actions or matters.

Mr. Diller is also currently the chairman of the Expedia Group Board and senior executive of Expedia Group. The Expedia Group certificate of incorporation provides that the chairman of the board may only be removed without cause by the affirmative vote of at least 80% of the entire board of directors, which provision may not be amended, altered changed or repealed, or any provision inconsistent therewith adopted, without the approval of at least (1) 80% of the entire Expedia Group Board and (2) 80% of the voting power of Expedia Group’s outstanding voting securities, voting together as a single class.

As a result of Mr. Diller’s ownership interests and voting power, and the governance arrangements between Mr. Diller and Expedia Group, it is expected that Mr. Diller will be in a position to influence, and potentially control, significant corporate actions, including corporate transactions such as mergers, business combinations or dispositions of assets. Additionally, in the future, another holder of the original shares might have such a position of influence by virtue of ownership interests in the original shares. This concentrated control could discourage others from initiating any potential merger, takeover or other change of control transaction that may otherwise be beneficial to Expedia Group stockholders.
