In connection with the proposed spin-off, Expedia, Inc. and TripAdvisor, Inc. have filed a registration statement on Form S-4 that included a preliminary proxy statement for Expedia and prospectus for Expedia and TripAdvisor with the SEC. Stockholders of Expedia are urged to read the definitive proxy statement/prospectus, when it becomes available, because it will contain important information about Expedia, the proposed spin-off transaction and related matters. Investors and security holders can obtain free copies of the definitive proxy statement/prospectus when it becomes available by contacting Investor Relations, Expedia, 333 108th Avenue N.E., Bellevue, Washington 98004 (Telephone: (425) 679-3555).

Expedia and its directors, executive officers and certain members of management and other employees may be deemed to be participants in the solicitation of proxies of Expedia’s stockholders to approve the proposed spin-off transaction. Such individuals may have interests in the transaction as described in Expedia’s proxy statement/prospectus, including as a result of current holdings of options, restricted share units or shares of Expedia’s stock and future holdings of options, restricted share units or shares of TripAdvisor’s stock, which will be impacted in the transaction.
