LightInTheBox Settles Class Action Lawsuit

— Company continues to focus on growing and strengthening its business operations —

Beijing, China, September 5, 2014 - LightInTheBox Holding Co., Ltd. (NYSE: LITB) (“LightInTheBox” or the “Company”), a global online retail company that delivers products directly to consumers around the world, today announced that it has entered into an agreement to settle all claims in a U.S. securities class action lawsuit. The settlement remains subject to preliminary and final court approval.

As previously disclosed, on August 27, 2013, the Company was named as a defendant in the first of three putative shareholder class action lawsuits filed in the United States District Court for the Southern District of New York. These three actions were consolidated under the master caption In re LightInTheBox Holding Co., Ltd. Securities Litigation, No. 13-cv-6016-VEC (S.D.N.Y.). On May 1, 2014, the Company filed a motion to dismiss the second amended consolidated complaint for failure to state a claim as a matter of law.

The parties have entered into the settlement prior to a decision on the Company’s motion to dismiss. According to the settlement, which remains subject to preliminary and final court approval, the Company and its insurers have agreed to contribute US$1.55 million to a settlement fund payable to certain purchasers of the American depositary shares between June 6, 2013 and August 19, 2013. In return, the lead plaintiff has agreed to dismiss all claims against the Company and all of the individual defendants.  Following final approval of the settlement by the Court, the case will not be allowed to be refiled.

The settlement is not an admission of wrongdoing or acceptance of fault by the Company or any of the individual defendants.  Indeed, the Company has and continues to believe that the allegations made in the consolidated lawsuits lack merit. The Company believes that the statements made in its initial public offering prospectus and during its road show were true and accurate portrayals of the Company’s business, and that the Company made detailed disclosures to inform investors of the potential risks to the Company’s business. The Company has nevertheless agreed to the settlement in order to eliminate the uncertainties, burden and expense of further litigation. The Company believes that putting this matter behind it is in the best interest of its customers, employees and shareholders so that it can remain focused on growing and strengthening its business.
