The company's shares plunged more than 10 percent in afterhours trading.
The largest daily deals company said net income for the fourth quarter was reduced by $22.6 million, while revenue was $14.3 million lower.
The revisions are primarily related to an increase to the company's refund reserve accrual to reflect a shift in the company's fourth quarter deal mix and higher price point offers, which have higher refund rates, it said in statement.
The company's shares were down to $16.59 in afterhours trading from a close of $18.38 on the Nasdaq.
