Expedia, Inc. (NASDAQ: EXPE) today announced financial results for the first quarter ended March 31, 2013. - Room nights grew 28% year-over-year for the first quarter of 2013 driven by continued acceleration at Brand Expedia and healthy room night growth at Hotels.com, eLong, Expedia Affiliate Network and Egencia. - Revenue grew 24% year-over-year for the first quarter of 2013 due to strong growth in the Americas, Europe and Asia-Pacific across most brands. Aided by strategic acquisitions, revenue growth in Europe during the first quarter of 2013 was more than five times the rate of growth in the first quarter of 2012. - Expedia, Inc. celebrated several milestones during the first quarter of 2013 including: Brand Expedia successfully migrating significant traffic to its new package platform; continued progress on the global roll-out of the Expedia® Traveler PreferenceTM (ETP) program with almost 25,000 contracted hotels; as well as passing the 30 million mobile app download mark collectively across Expedia, Inc.’s leisure brands. - Expedia, Inc. completed the acquisition of 61.6% of the fully-diluted equity of trivagoTM GmbH, a leading hotel metasearch company, in March 2013. In addition, year to date, the company repurchased 2.0 million common shares for a total of $127 million. Expedia reduced its forecast for growth in organic earnings before interest, taxes, depreciation, and amortization (EBITDA) by $20 million-$30 million, citing weakness at Hotwire. The company, however, reaffirmed its overall 2013 forecast for adjusted EBITDA of growth in the low double digits due to strong performance at trivago - a German travel site in which it acquired a majority stake earlier this year. Expedia said troubles at Hotwire began with superstorm Sandy in October. The recent consolidation in the car rental industry made matters worse as it drove up rental rates, discouraging its price-sensitive customers, Expedia said on the call.
