What happened

Shares of Priceline Group Inc. (NASDAQ:BKNG) were climbing today after the online travel agent turned in another strong quarterly earnings report. As of 12:41 p.m. EST, the stock had gained 5.4%.

So what

Priceline, which owns properties including Kayak, Booking.com, and Agoda in addition to its namesake site, delivered a 17.4% increase in revenue to $2.35 billion; this topped estimates at $2.32 billion, thanks to a 31% jump in room nights booked. That was the fastest growth in Priceline's biggest segment in at least two years.

On the bottom line, adjusted earnings per share surged 32% to $14.21, easily beating expectations at $13.01. CEO Glenn Fogel noted that the company saw "solid organic growth and attractive profit margins" in its hotel segment, and credited accelerating growth on its "scaled accommodations platform and strong execution by our global teams."

Now what

Priceline actually undershot expectations for the current quarter, with its guidance calling for adjusted EPS of $8.25 to $8.65, compared to estimates at $10.62. The market seemed to overlook that as the guidance was otherwise solid, calling for an increase in total travel bookings of 17% to 22% and gross profit growth of 9.5% to 14.5%. Priceline has a habit of giving conservative guidance, so I'd expect the company to top that EPS number, especially given the strong momentum from the fourth quarter.

With hotel bookings growth accelerating, 2017 looks like it could be another winning year for Priceline Group. Thanks to its family of popular travel sites and commission-based business model, its stock has been hard to beat.
