BEIJING, June 1, 2015 (GLOBE NEWSWIRE) — Qunar Cayman Islands Limited (NASDAQ: QUNR) (“Qunar” or the “Company”), China’s leading mobile and online travel platform, today announced its unaudited financial results for the first quarter ended March 31, 2015.

Highlights for the First Quarter of 2015

·Total revenues for the first quarter of 2015 were RMB671.1million (US$108.3 million), an increase of 100.0% year-on-year.

·Mobile revenues for the first quarter of 2015 were RMB398.5 million (US$64.3 million), an increase of 275.7% year-on-year, representing 59.4% of total revenues, compared to 31.6% in the corresponding period of 2014.

·Total Estimated Flight Ticket volume (TEFT) and Total Estimated Hotel Room-night volume (TEHR) for the first quarter of 2015 were 27.0 million and 10.7 million, respectively, an increase of 54.0% and 81.7% year-on-year.

“Qunar’s momentum for revenue growth and market share expansion across business lines remained robust in Q1 2015 as our quarterly GMV expanded to over RMB30 billion for the first time,” said Chenchao (CC) Zhuang, chief executive officer and co-founder of Qunar.

“We are one of the largest e-commerce companies in China and the fastest growing, and this is the fourth consecutive quarter that our year-on-year revenue grew 100% or above,” Mr. Zhuang added.  “Once again, mobile continued to be the key driver and now contributed 59.4% of our total revenues, thanks to our large and loyal mobile user base.”

“We will continue to capitalize the offline to mobile tailwind in the travel industry and to drive Qunar’s long-term growth with an aggressive and deliberate investment approach,” said Yilu Zhao, Chief Financial Officer of Qunar.

First Quarter 2015 Financial Results

Total revenues for the first quarter of 2015 were RMB671.1 million (US$108.3 million), an increase of 100.0% year-on-year and 29.1% quarter-on-quarter.

Mobile revenues for the first quarter of 2015 were RMB398.5 million (US$64.3 million), an increase of 275.7% year-on-year, representing 59.4% of total revenues.

Flight and flight related revenues for the first quarter of 2015 were RMB457.3 million (US$73.8 million), an increase of 94.3% year-on-year and 32.8% quarter-on-quarter. Year-on-year flight and flight related revenue growth was primarily due to a 54.0% increase in TEFT and a 26.1% increase in revenue per ticket.

Accommodation reservation revenues were RMB128.3 million (US$20.7 million), an increase of 107.6% year-on-year and 25.5% quarter-on-quarter. Year-on-year accommodation reservation revenue growth was primarily due to an 81.7% increase in TEHR and 14.3% increase in revenue per room night.

Gross profit for the first quarter of 2015 was RMB490.5 million (US$79.1 million), an increase of 87.1% year-on-year. Gross margin for the first quarter of 2015 was 73.1%, compared to 78.1% for the corresponding period of 2014 and 73.5% for the fourth quarter of 2014. The year-on-year increase in gross profit during the quarter was primarily due to the significant increase in total revenues, and was partially offset by an increase in online payment processing fees.

Product development expenses for the first quarter of 2015 were RMB287.1 million (US$46.3 million), an increase of 136.7% year-on-year, primarily due to an increase in salary, welfare and other expenses associated with headcount increases. Excluding share-based compensation expenses, product development expenses were RMB267.5 million (US$43.2 million), an increase of 152.6% year-on-year, and accounted for 39.9% of total revenues, compared to 31.6% for the corresponding period of 2014 and 43.4% for the fourth quarter of 2014.

Product sourcing expenses for the first quarter of 2015 were RMB124.4 million (US$20.1 million), an increase of 219.5% year-on-year, primarily due to an increase in product sourcing headcount. Excluding share-based compensation expenses, product sourcing expenses were RMB123.3 million (US$19.9 million), an increase of 222.0% year-on-year, and accounted for 18.4% of total revenues, compared to 11.4% for the corresponding period of 2014 and 20.9% for the fourth quarter of 2014.

Sales and marketing expenses for the first quarter of 2015 were RMB327.9million (US$52.9 million), an increase of 150.7% year-on-year, primarily due to an increase in salary and welfare expenses as a result of increased headcount, as well as an increase in online marketing expenses and advertising and other promotion expenses. The headcount expenses under sales and marketing were primarily expenses related to personnel with operational functions, including our customer service staff, photographers, editors, and staff responsible for data analysis. Excluding share-based compensation expenses, sales and marketing expenses were RMB320.2 million (US$51.6 million), an increase of 148.7% year-on-year, and accounted for 47.7% of total revenues, compared to 38.4% for the corresponding period of 2014 and 52.9% for the fourth quarter of 2014.

General and administrative expenses for the first quarter of 2015 were RMB132.1 million (US$21.3 million), an increase of 68.6% year-on-year, primarily due to an increase in share-based compensation, salary and welfare expenses associated with headcount increases. Excluding share-based compensation expenses, general and administrative expenses were RMB70.6 million (US$11.4 million), an increase of 91.2% year-on-year, and accounted for 10.5% of total revenues, compared to 11.0% for the corresponding period of 2014 and 11.6% for the fourth quarter of 2014.

Online marketing expenses for the Company’s Baidu Zhixin Cooperation for the first quarter of 2015 were RMB30.3 million (US$4.9 million), a decrease of 54.7% year-on-year. The decrease was primarily due to a significant decrease in Zhixin-related page views acquired during the period. Online marketing expenses from the Zhixin Cooperation Agreement were non-cash expenses and recognized ratably over the period of service required to earn each tranche of warrants based upon the estimated exercisable number of the Baidu warrants and the fair value of the warrants at each reporting date.

Operating loss for the first quarter of 2015 was RMB411.2 million (US$66.3 million), compared to RMB174.1 million in the corresponding period of 2014 and RMB666.6 million in the fourth quarter of 2014.

Operating loss on a non-GAAP basis, which excludes share-based compensation expenses of RMB89.9 million (US$14.5 million) and online marketing expenses from the Zhixin Cooperation Agreement of RMB30.3 million (US$4.9 million), was RMB291.0 million (US$46.9 million) for the first quarter of 2015. Operating margin (non-GAAP) for the first quarter of 2015 was negative 43.4%, compared to negative 13.8% in the corresponding period of 2014 and negative 55.2% in the fourth quarter of 2014. The year-on-year increase in operating loss was mainly attributable to continued investment in product development and product sourcing to drive business growth, especially development of the Company’s hotel direct business.

Fair value change in warrant liability for the first quarter of 2015 was RMB288.2 million (US$46.5 million), representing changes in the fair value of vested tranche of the Baidu warrants.  Such warrants were granted in previous year and continuously accounted for as a liability when vested and exercisable in the first quarter of 2015 and therefore measured at fair value at every reporting period until they are exercised or settled. No warrants were vested in 2014 and hence there was no such fair value change in the corresponding period of 2014 and the fourth quarter of 2014, respectively.

Net loss attributable to Qunar’s shareholders for the first quarter of 2015 was RMB701.2 million (US$113.1 million), compared to RMB183.6 million in the corresponding period of 2014 and RMB675.5 million in the fourth quarter of 2014. The increase in net loss was primarily due to reasons mentioned above.  Basic and diluted net loss per ADS for the first quarter of 2015 was RMB5.85 (US$0.96).

Adjusted net loss (non-GAAP), defined as net loss excluding share-based compensation expenses of RMB89.9 million (US$14.5 million), online marketing expenses from the Zhixin Cooperation Agreement of RMB30.3 million (US$4.9 million) and fair value change in warrant liability of RMB288.2 million (US$46.5 million), for the first quarter of 2015 was RMB293.4 million (US$47.3 million), compared to adjusted net loss of RMB55.7 million in the corresponding period of 2014 and adjusted net loss of RMB295.9 million in the fourth quarter of 2014.

Adjusted EBITDA (non-GAAP), defined as net loss before income tax expense, depreciation and amortization, interest expense, further adjusted to exclude share-based compensation expenses of RMB89.9 million (US$14.5 million), online marketing expenses from the Zhixin Cooperation Agreement of RMB30.3 million (US$4.9 million), fair value change in warrant liability of RMB288.2 million (US$46.5 million), for the first quarter of 2015 was negative RMB262.5 million (US$42.4 million), compared to negative RMB45.8 million in the corresponding period of 2014 and negative RMB268.8 million in the fourth quarter of 2014.

As of March 31, 2015, Qunar had cash and cash equivalents, restricted cash and funds receivable of RMB1.4 billion (US$232.3 million). Qunar entered into a US$300 million revolving credit facility agreement with Baidu on February 27, 2014. The agreement has a term of three years and any drawdown bears an annual interest rate of 90% of the benchmark lending rate published by the People’s Bank of China and shall be repaid within three years from the drawdown date. We may repay our outstanding debt obligation at maturity either by cash or by our shares. The applicable share conversion price will be determined by the prevailing share price at the maturity date. On March 12 and May 4, 2015, Qunar drew down RMB507 million and RMB627 million, respectively, from Baidu according to the revolving credit facility agreement with the plan to use the funds for the Company’s operational and investment needs. As of April 30, 2015, Qunar had 224,299,179 Class A ordinary shares and 136,123,641 Class B ordinary shares outstanding.

Recent Events

On May 8, 2015, we received an unsolicited offer from Ctrip.com International, Ltd., or Ctrip, to acquire all of our outstanding shares.  After careful consideration of such offer, we declined to pursue it in a letter response dated June 1, 2015.  However, consistent with our policy to consider all potential strategic opportunities that may benefit our company and our shareholders, we remain open to engaging in further discussions with Ctrip as well as with other strategic players in our sector.

On June 1, 2015, Baidu and we agreed to terminate the Zhixin cooperation agreement with immediate effect. We believe the termination is in the best interests of the shareholders of both companies.  Under this agreement, in consideration of the Zhixin page views Baidu delivered to us in 2014, Baidu was granted warrants exercisable for 11.45 million of our class B ordinary shares and Baidu fully exercised such warrants today.  There will be no additional warrants granted to Baidu under this agreement. In connection with the termination of the Zhixin cooperation agreement, Baidu agreed to pay us a fee of RMB207 million. Baidu’s undertaking and support for us, including their non-compete commitment in the travel space, will remain unchanged after the termination of the Zhixin cooperation agreement, and we do not expect the termination of this agreement to have any material impact upon our operations or financial condition.

On June 1, 2015, we also entered into a business cooperation agreement with Baidu, under which Baidu has agreed to grant Qunar an exclusive right to integrate hotel information and products into the PC and mobile app versions of Baidu Maps. Under this agreement, Qunar will display location-based hotel data through the Baidu Maps interface. Users can click on the displayed hotels to view hotels and to complete bookings. This cooperation will allow Qunar and Baidu to serve travelers with highly relevant real-time hotel information. This agreement will expire in May 2016 subject to the renewal negotiation between both parties.

Business Outlook

For the second quarter of 2015, Qunar expects year-on-year revenue growth in the estimated range of 105% to 110% and non-GAAP operating margin to be in the range of negative 90% to 100%, in comparison to negative 43.4% in the first quarter of 2015. The significant quarter-on-quarter increase in operating expenses is primarily due to stepped up discretionary expenditures to acquire new mobile users through offline channels, and to a lesser extent, increase in per person headcount expenses based on a relatively stable staff size.  Such offline marketing activities are expected to continue for the remainder of 2015 as the company continues to increase rapidly its mobile user base. Corresponding revenue growth is expected to be meaningfully less than the increase in marketing expenses in 2015, resulting in a decrease in non-GAAP operating margins.  The trend in year-on-year revenue growth and the non-GAAP operating margin for Q2 are expected to continue for the fiscal year 2015. Qunar continues to expect to turn profitable on a quarterly non-GAAP EBIT basis, by the end 2016. These forecasts reflect Qunar’s current and preliminary view based on current market and operating conditions, which is subject to change, and such change may be material.

About Non-GAAP Financial Measures

To supplement Qunar’s consolidated financial results presented in accordance with United Statements Generally Accepted Accounting Principles (“GAAP”), Qunar also uses adjusted net income (loss), adjusted EBITDA and adjusted operating income (loss) as additional non-GAAP financial measures. These non-GAAP financial measures enable management to assess the Company’s operating results without considering the impact of noncash charges, including share-based payments, depreciation and amortization, online marketing expenses from the Zhixin Cooperation Agreement and fair value change in warrant liability. Furthermore, these non-GAAP financial measures eliminate the impact of items that Qunar does not consider indicative of the performance of its business.

Qunar presents these non-GAAP financial measures because they are used by management to evaluate its operating performance, formulate business plans, and make strategic decisions on capital allocation. Qunar also believes that these non-GAAP financial measures provide useful information to investors and others in understanding and evaluating its operating performance and consolidated results of operations in the same manner as management and in comparing financial results across accounting periods and to those of its peer companies. The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. A limitation of using these non-GAAP financial measures is that these non-GAAP measures do not include all items that impact the Company’s results of operations for the period. The table captioned “Reconciliations of GAAP and non-GAAP Measures” has more details on the reconciliations between GAAP financial measures that are most directly comparable to the non-GAAP financial measures.
