Groupon tumbles after weak 1Q revenue outlook

The guidance fueled investor worry that people are tiring of the myriad of online restaurant, spa and Botox deals that Groupon built its business on, and that the company's efforts to broaden into an e-commerce powerhouse haven't been paying off.

The Chicago-based company booked a net loss of $81.1 million, or 12 cents per share, in the October-December period. That compares with a loss of $65.4 million, also 12 cents per share, in the same period a year earlier when it had fewer shares outstanding.

Analysts were expecting a loss of 2 cents a share, according to FactSet.

Revenue rose 30 percent to $638.3 million from $492.2 million. Wall Street had expected revenue of $639.8 million.

Gross billings, a closely watched figure that shows the total amount that customers spent on Groupon's deals, increased 24 percent in the quarter to $1.52 billion from $1.23 billion a year earlier.
