Qunar Updates its Dispute with eLong

BEIJING, China, January 2, 2015 — Qunar Cayman Islands Limited (NASDAQ:QUNR) (“Qunar” or the “Company”), today announced that on January 1, 2015, it received the judgment (the “Judgment”) of the Beijing No.1 Intermediate People’s Court (the “Court”) with respect to the contract dispute under an Inventory Distribution Agreement for hotels with eLong, which was previously described in the Company’s annual report on Form 20-F for the fiscal year of 2013.

In the Judgment, the Court held that (i) eLongNet Information Technology (Beijing) Co., Ltd. (“eLongNet”), a subsidiary of eLong, shall pay our subsidiary, Beijing Qunar Software Technology Co., Ltd. (“Beijing Qunar”), a commission of RMB8,127,400 (approximately US$1.3 million) due under the Inventory Distribution Agreement; (ii) Beijing Qunar shall prospectively credit to eLongNet’s advertisement account opened at Beijing Qunar in the future in the amount of RMB52,335,369 (approximately US$8.5 million) corresponding to the period up to September 30, 2014; and (iii) the Inventory Distribution Agreement shall continue to be performed by both parties.

The Company does not believe that the Judgment will have a material impact on its business. The Company has rapidly expanded its hotel direct business since 2013 to cover 223,000 hotels by the end of September 2014. As a result, the hotel direct sales has continued to increase and contributed 51% of the Company’s total hotel volume for the third quarter of 2014.

Under the PRC laws, both parties have the right to appeal to the Beijing High People’s Court within 15 days upon its receipt of the Judgment. The Company plans to appeal and continuously defend its rights under the Inventory Distribution Agreement.
