Renren Announces Unaudited First Quarter 2014 Financial Results

BEIJING, China, May 21, 2014 — 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 first quarter ended March 31, 2014.

First Quarter 2014 Highlights

·                  Total net revenues were US$24.9 million, a 39.9% decrease from the corresponding period in 2013.

·                  Renren net revenues were US$12.2 million, a 17.3% decrease from the corresponding period in 2013.

·                  Games net revenues were US$12.7 million, a 52.5% decrease from the corresponding period in 2013.

·                  Gross profit was US$8.7 million, a 65.2% decrease from the corresponding period in 2013.

·                      Operating loss was US$29.2 million, compared to an operating loss of US$20.4 million in the corresponding period in 2013.

·                      Net income attributable to the Company was US$32.3 million, compared to a net loss of US$3.1 million in the corresponding period in 2013.

·                      Adjusted net income (1) (non-GAAP) was US$36.1 million, compared to an adjusted net income of US$0.5 million in the corresponding period in 2013.

“First quarter revenues, as expected, remained under pressure from the challenges in advertising and gaming that we have faced for some quarters.  On the positive side, the portion of advertising from mobile is growing and the interest from brand advertisers for the young target demographic that Renren serves is notably increasing. Meanwhile, we are pleased to see strong growth in the amount of UGC videos uploaded to our on-line video site, 56.com, along with its increasing traffic”, commented Joseph Chen, Chairman and Chief Executive Officer. “We remain committed in building and realizing long-term value for our shareholders.”

First Quarter 2014 Results

Total net revenues for the first quarter of 2014 were US$24.9 million, representing a 39.9% decrease from the corresponding period in 2013.

Renren net revenues were US$12.2 million, representing a 17.3% decrease from the corresponding period of 2013. Within Renren net revenues, online advertising revenues were US$7.8 million for the first quarter of 2014, a 19.2% decrease from the corresponding period of 2013. The decrease was due to increasing competition and traffic migration to mobile. Internet Value-Added Services (IVAS) revenues were US$4.4 million, representing a 13.6% decrease from the corresponding period in 2013. The number of accumulated activated users on renren.com increased from approximately 184 million as of March 31, 2013 to approximately 210 million as of March 31, 2014. Monthly unique log-in users in March 2014 was approximately 51 million, compared to approximately 57 million in March 2013 and approximately 45 million in December 2013.

Games net revenues were US$12.7 million for the first quarter of 2014, a 52.5% decrease from the corresponding period of 2013.  The decrease was due to previously launched games having reached mature stages and the earlier disclosed delay of new games release.

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

Cost of revenues was US$16.2 million, a 1.0% decrease from the corresponding period of 2013.

Operating expenses were US$38.0 million, a 16.7% decrease from the corresponding period of 2013.

Selling and marketing expenses were US$10.8 million, a 16.0% decrease from the corresponding period of 2013. The decrease was primarily due to the decreased marketing related expenses and promotions for online games.

Research and development expenses were US$15.7 million, a 30.5% decrease from the corresponding period in 2013. The decrease was primarily due to headcount reduction and decrease in personnel related expenses.

General and administrative expenses were US$11.4 million, a 12.1% increase from the corresponding period in 2013.  The increase was primarily due to the increase in office rents and share-based-compensation expenses.

Share-based compensation expenses, which were all included in operating expenses, were US$3.4 million, compared to US$3.2 million in the corresponding period in 2013.

Operating loss was US$29.2 million, compared to an operating loss of US$20.4 million in the corresponding period in 2013.

Realized gain on short-term investments was US$27.1 million, compared to US$15.1 million in the corresponding period in 2013. The gain was primarily derived from the sale of marketable securities.

Gain on disposal of equity method investment, net of income taxes was US$57.1 million, due solely to the one-time gain from the disposal of our remaining equity interest in Nuomi.

Net income attributable to the Company was US$32.3 million, compared to a net loss of US$3.1 million in the corresponding period in 2013. This was primarily due to the US$57.1 million gain on the disposal of equity method investment.

Adjusted net income (non-GAAP) was US$36.1 million, compared to an adjusted net income of US$0.5 million in the corresponding period in 2013. The increase was primarily due to the US$57.1 million gain on the disposal of equity method investment. Adjusted net income (loss) is defined as net income (loss) excluding share-based compensation expenses, amortization of intangible assets and impairment of intangible assets.

Share Repurchase Program Update and Extension

As of May 20, 2014, Renren had repurchased approximately 22.4 million ADSs under the current repurchase program for a total consideration of US$68.4 million.  The current share repurchase program will expire on June 27, 2014.  Our board has recently authorized another share repurchase program of US$100 million for one year effective from June 28, 2014.

Business Outlook

The Company expects to generate revenues in an amount ranging from US$21 million to US$23 million in the second quarter of 2014, representing a 47.1% to 51.7% 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 net income (loss) 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.
