On an adjusted basis, Expedia earned 84 cents per share in the fourth quarter, falling well short of analysts' average estimate of $1.15, according to Thomson Reuters I/B/E/S. Expedia's HomeAway vacation rental business, a rival to Airbnb, reported a 16 percent jump in revenue to $193 million in the fourth quarter, compared with analysts' average estimate of $225.4 million, according to Thomson Reuters I/B/E/S. Expedia's previous quarterly report was equally disappointing to investors when reported last year, though that period included headwinds from a rash of disruptive hurricanes off the Atlantic in addition to brand shortcomings. Trivago GmbH, majority owned by Expedia, reported a bigger-than-expected fourth-quarter loss on Wednesday as the hotel search platform spent more on sales and marketing. "Trivago does face extremely tough revenue and profitability comps through the first half of 2018," Okerstrom said on the Thursday call.
