We also successfully incorporated mobile marketing into our service portfolio through our cooperation with leading social media platforms Weibo and Weixin. In a softer primary real estate market, our new mobile platform and various product launches allow us to offer differentiated advantages and deliver positive results for our clients as they turn to us for support in marketing and promoting their projects.”

“Looking ahead, we expect that China’s real estate market will continue to experience a period of change, and we remain committed to executing on our business strategies in 2015,” Mr. He continued. “We believe the e-commerce market offers unique opportunities and we plan to further grow this business through the use of mobile solutions. We will stay focused on building a transparent informational platform in the secondary listing business through the promotion of reliable home data using our verified listing model along with our brokerage partners. Furthermore, we also plan to expand our home furnishing business in 2015 through a new platform that brings together customers with individual contractors, who serve a pivotal role in home furnishing projects. We believe that our service-oriented business model and strong online and offline execution make us well-positioned to address our clients’ marketing needs and generate and capture further growth.”

“We are reporting strong top-line growth, with our e-commerce business in particular delivering another year of high revenue growth,” said Ms. Min Chen, Leju’s chief financial officer. “We generated strong operating cash flows for the year which will support the company’s operations and strategic investments in 2015.”

Fourth Quarter 2014 Results

Total revenues were $171.8 million, an increase of 36% from $126.4 million for the same quarter of 2013, mainly driven by growth of revenues from e-commerce services.

Revenues from e-commerce services were $124.5 million, an increase of 61% from $77.5 million for the same quarter of 2013, primarily due to a 28% increase in discount coupons redeemed,2 as a result of the expansion of the Company’s e-commerce business through partnerships with property developers.

About Non-GAAP Financial Measures

To supplement Leju’s consolidated financial results presented in accordance with United States Generally Accepted Accounting Principles (“GAAP”), Leju uses in this press release the following non-GAAP financial measures: (1) income (loss) from operations, (2) net income (loss), (3) net income (loss) attributable to Leju shareholders, (4) net income (loss) attributable to Leju shareholders per basic ADS, and (5) net income (loss) attributable to Leju shareholders per diluted ADS, each of which excludes share-based compensation expense and amortization of intangible assets resulting from business acquisitions. 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. For more information on these non-GAAP financial measures, please see the table captioned “Unaudited Reconciliation of GAAP and Non-GAAP Results” set forth at the end of this press release.

Leju believes that these non-GAAP financial measures provide meaningful supplemental information to investors regarding its operating performance by excluding share-based compensation expense, and amortization of intangible assets resulting from business acquisitions, which may not be indicative of Leju’s operating performance. These non-GAAP financial measures also facilitate management’s internal comparisons to Leju’s historical performance and assist its financial and operational decision making. A limitation of using these non-GAAP financial measures is that share-based compensation expense and amortization of intangible assets resulting from business acquisitions may continue to exist in Leju’s business for the foreseeable future. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from each non-GAAP measure. The accompanying tables provide more details on the reconciliation between non-GAAP financial measures and their most comparable GAAP financial measures.
