(Nasdaq: CTRP), a leading travel service provider of accommodation reservation, transportation ticketing, packaged tours and corporate travel management in China, today announced its unaudited financial results for the quarter ended March 31, 2014.

Highlights for the First Quarter of 2014

·                      Operating margin was 4% for the first quarter of 2014, compared to 14% in the same period in 2013. Excluding share-based compensation charges (non-GAAP), operating margin was 12%, compared to 23% in the same period in 2013.

·                      Net income attributable to Ctrip’s shareholders was RMB115 million (US$19 million) for the first quarter of 2014, down 25% year-on-year. Excluding share-based compensation charges (non-GAAP), net income attributable to Ctrip’s shareholders was RMB237 million (US$38 million), down 11% year-on-year.

“We are pleased to report the great performance in the first quarter of 2014,” said James Liang, Chairman and Chief Executive Officer of Ctrip. “We recently expanded our traditional hotel reservation and ticketing services to accommodation reservation and transportation ticketing services. The growth of both businesses is on the accelerating track with volume increasing 67% and 71% year-on-year, respectively. Total mobile transaction value was over four times the level in the first quarter of 2013 with peak daily transaction value reaching about RMB150 million. Mobile has surpassed PC Internet to be the most important booking platform for our accommodation reservation business, contributing over 40% of our transactions during the quarter and over 60% on the peak day. We are also very proud to see our new businesses start to take leading positions. For example, Ctrip Travel Community Channel experienced over 300% year-on-year growth in daily unique visitors and became the top player among travel information and community websites in China.

In addition, we recently became the second largest shareholder of LY.com and one of anchor investors for Tuniu.com in connection with its proposed IPO. As a leading player in the online and mobile travel market in China, we are seeing great potential in the industry. LY.com is a leading player in the local attraction ticket segment and Tuniu.com is strong in leisure package tour business. Ctrip is looking forward to working together with industry peers to create greater value for our customers and partners and to help develop a healthy and flourishing travel industry in China.”

About Non-GAAP Financial Measures

To supplement Ctrip’s unaudited condensed consolidated financial statements presented in accordance with United States Generally Accepted Accounting Principles (“GAAP”), Ctrip uses non-GAAP financial information related to product development expenses, sales and marketing expenses, general and administrative expenses, income from operations, operating margin, net income, and diluted earnings per ordinary share and per ADS, each of which is adjusted from the most comparable GAAP result to exclude the share-based compensation charges recorded under ASC 718, “Compensation-Stock Compensation” for 2014 and 2013. Ctrip’s management believes the non-GAAP financial measures facilitate better understanding of operating results from quarter to quarter and provide management with a better capability to plan and forecast future periods.

Non-GAAP information is not prepared in accordance with GAAP and may be different from non-GAAP methods of accounting and reporting used by other companies. The presentation of this additional information should not be considered a substitute for GAAP results. A limitation of using non-GAAP financial measures is that non-GAAP measures exclude share-based compensation charges that have been and will continue to be significant recurring expenses in Ctrip’s business for the foreseeable future.

Reconciliations of Ctrip’s non-GAAP financial data to the most comparable GAAP data included in the consolidated statement of operations are included at the end of this press release.
