The Complaint alleges that throughout the Class Period, Groupon made false and/or misleading statements, as well as failed to disclose material adverse facts about the adequacy of the Company's internal financial controls, and the Company's reported financial results for the fourth quarter of 2011.

On Friday, March 30, 2012, Groupon disclosed that: (a) it had materially understated refund reserves for fourth quarter 2011 ("Q4 2011") due to a failure to properly account for coupon refunds; (b) as a result, it had materially misstated previously reported Q4 2011 and Full-Year 2011 revenue, operating income (loss), operating expense, net income (loss), earnings (loss) per share, and cost of revenue; and (c) internal controls over its financial statements had material weaknesses.

As a result of the revelations, Groupon's stock declined. On Monday, April 2, 2012, the first trading day following Groupon's disclosures, the Company's stock closed on extraordinarily high volume of 10.09 million shares at $15.27 – a single-trading-day decline of $3.11 or 16.9% from its prior close.
