Yates Jr., P.C. that it has filed a class United States District Court for the Northern District of Illinois on behalf of purchasers of Groupon, Inc. ("Groupon") (NASDAQ: GRPN) common stock during the period between May 14, 2012 and November 8, 2012 (the "Class Period").  If you wish to discuss this action or have any questions concerning this notice or your rights or interests, please contact plaintiff's counsel, Alfred G. Yates Jr., at 1-800-391-5164, toll free, or at yateslaw@aol.com by e-mail. Please visit http://yatesclassactionlaw.com.

If you wish to serve as lead plaintiff, you must move the Court no later than February 19, 2013.  The complaint alleges defendants issued materially false and misleading statements regarding Groupon's business which led to an inflated stock price during the Class Period, reaching a high of $13.05 per share on May 16, 2012.  On November 8, 2012, Groupon issued a press release announcing its third quarter 2012 earnings results, reporting disappointing revenue results for the third quarter and lowered revenue guidance for the fourth quarter of 2012 below analysts' expectations.  As a result of this news, Groupon stock dropped $1.16 per share to close at $2.76 per share on November 9, 2012, a one-day decline of nearly 30% and a decline of 78% from the stock's Class Period high.
