Renren Announces Unaudited Third Quarter 2013 Financial Results

BEIJING, China, November 27, 2013 — Renren Inc. (NYSE: RENN) (“Renren” or the “Company”), a leading real-name social networking internet platform in China, today announced its unaudited financial results for the third quarter ended September 30, 2013.

Third Quarter 2013 Highlights

·                  Total net revenues were US$47.6 million, a 5.6% decrease from the corresponding period in 2012.  Renren net revenues were US$41.1 million, a 9.9% decrease from the corresponding period in 2012.  Nuomi net revenues were US$6.5 million, a 36.0% increase from the corresponding period in 2012.

·                  Gross profit was US$30.0 million, a 3.0% decrease from the corresponding period in 2012.

·                  Operating loss was US$35.5 million, compared to an operating loss of US$20.6 million in the corresponding period in 2012.

·                  Net loss attributable to the Company was US$24.6 million, compared to a net loss of US$15.4 million in the corresponding period in 2012.

·                  Adjusted net loss (non-GAAP) (1) was US$19.7 million, compared to an adjusted net loss of US$12.1 million in the corresponding period in 2012.

“Revenues came within guidance in the third quarter. While we continue to face short-term monetization challenges, our strategies are becoming more focused and clear. The recent launch of our communication-oriented Renren mobile app tailored for the young generation will help us strengthen our dominance in this important demographic.  Meanwhile, the restructuring of our gaming business will also make us more focused on developing high-quality games. As we head into the final stretch of the year, we will stay focused on our highest priorities and further fine tune our strategies,” commented Joseph Chen, Chairman and Chief Executive Officer.

Third Quarter 2013 Results

Total net revenues for the third quarter of 2013 were US$47.6 million, representing a 5.6% decrease from the corresponding period in 2012.

Renren net revenues were US$41.1 million, representing a 9.9% decrease from the corresponding period of 2012. Within Renren net revenues, online game revenues were US$20.1 million for the third quarter of 2013, a 16.9% decrease from the corresponding period of 2012. The decrease was due to our launched games reaching mature stages. Other IVAS revenues were US$6.1 million for the third quarter of 2013, a 32.1% increase from the corresponding period of 2012. The increase was largely due to increased revenue from Woxiu, our virtual talent show service on 56.com. Online advertising revenues were US$14.9 million for the third quarter of 2013, representing a decrease of 11.2% from the corresponding period of 2012. The decrease was due to the continuing migration of our traffic from PC to mobile coupled with increasing competition. The number of accumulated activated users on Renren.com continued to increase from approximately 172 million as of September 30, 2012 to approximately 200 million as of September 30, 2013. Monthly unique log-in users increased from approximately 48 million in September 2012 to approximately 50 million in September 2013.

(1)         Adjusted net income (loss) is a non-GAAP measure, which is defined as income (loss) from continuing operations excluding share-based compensation expenses, amortization of intangible assets and impairment of intangible assets.

Nuomi net revenues were US$6.5 million, representing a 36.0% increase from the corresponding period of 2012.  Nuomi had 3.8 million active paying users for the third quarter of 2013 compared to 3.1 million for the corresponding period of 2012, a 21.9% increase.

Cost of revenues was US$17.6 million, a 9.7% decrease from the corresponding period of 2012.   The decrease in cost of revenues for the third quarter was largely due to the reduction in games’ direct costs.

Operating expenses were US$65.5 million, a 27.1% increase from the corresponding period of 2012.

Selling and marketing expenses were US$28.5 million, a 33.5% increase from the corresponding period of 2012. The increase was primarily due to headcount and personnel related expense increases for Nuomi plus increased advertising and promotions for our launched games.

Research and development expenses were US$22.4 million, a 7.3% increase from the corresponding period in 2012. The increase was primarily due to headcount and personnel related expense increases for games development and mobile-related investments.

General and administrative expenses were US$14.6 million, a 56.8% increase from the corresponding period in 2012.  The increase was primarily due to an increase in share-based compensation charges and increased personnel related expenses due to the growth of our company size and business operations.

Share-based compensation expenses, which were mostly included in operating expenses, were US$4.5 million, compared to US$2.6 million in the corresponding period in 2012.

Operating loss was US$35.5 million, compared to an operating loss of US$20.6 million in the corresponding period in 2012.

Net loss attributable to Renren Inc. was US$24.6 million, compared to a net loss of US$15.4 million in the corresponding period in 2012.

Adjusted net loss (non-GAAP) was US$19.7 million, compared to an adjusted net loss of US$12.1 million in the corresponding period in 2012. Adjusted net income (loss) is defined as income (loss) from continuing operations excluding share-based compensation expenses, amortization of intangible assets and impairment of intangible assets.

Share Repurchase Program

On June 28, 2013, the Company announced a new share repurchase program to repurchase up to US$100 million of its ADSs and shares.  During the third quarter of 2013, Renren repurchased approximately 3.7 million ADSs.

Business Outlook

The Company expects to generate revenues in an amount ranging from US$29 million to US$31 million in the fourth quarter of 2013, representing 36% to 41% year-over-year decline. This forecast reflects Renren’s current and preliminary view, which is subject to change.

About Non-GAAP Financial Measures

To supplement Renren’s consolidated financial results presented in accordance with United States Generally Accepted Accounting Principles (“GAAP”), Renren uses “adjusted net income (loss),” which is defined as “a non-GAAP financial measure” by the SEC, in evaluating its business. We define adjusted net income (loss) as income (loss) from continuing operations excluding share-based compensation expenses, amortization of intangible assets and impairment of intangible assets. We present adjusted net income (loss) because it is used by our management to evaluate our operating performance. We also believe that this non-GAAP financial measure provide useful information to investors and others in understanding and evaluating our consolidated results of operations in the same manner as our management and in comparing financial results across accounting periods and to those of our peer companies.

The presentation of this non-GAAP financial measure is not intended to be considered in isolation from, 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 “Reconciliation of non-GAAP results of operations measures to the comparable GAAP financial measures” at the end of this release.
