　　First Quarter 2011 Highlights

　　•Net revenues grew 18% year over year to $100.2 million. Non-GAAP net revenues grew 19% year over year to $95.5 million, reaching the high end of the Company’s previous guidance of between $93 million and $96 million.

　　•Non-advertising revenues decreased 9% year over year to $27.9 million. Non-GAAP non-advertising revenues decreased 11% year over year to $23.2 million, exceeding the previous guidance of between $22 million and $23 million.

Non-GAAP net income attributable to SINA decreased 24% year over year to $16.9 million, or $0.25 non-GAAP diluted net income per share attributable to SINA.

　　“SINA’s online advertising growth was strong in the first quarter, despite a high comparison basis from last year” said Charles Chao, CEO of SINA, “The momentum for Weibo adoption is building across China. With the launch of the official Weibo.com, registered users for Weibo recently surpassed 140 million. We hope to ride this momentum and further expand Weibo’s user base and user stickiness by significantly increasing our investment in the coming quarters.”

　　First Quarter 2011 Financial Results

　　For the first quarter of 2011, SINA reported net revenues of $100.2 million, compared to $85.0 million for the same period last year. Non-GAAP net revenues for the first quarter of 2011 totaled $95.5 million, compared to $80.3 million for the same period last year. Advertising revenues for the first quarter of 2011 were $72.3 million, compared to $54.3 million for the same period last year.

　　Non-advertising revenues for the first quarter of 2011 totaled $27.9 million, compared to $30.7 million for the same period last year. MVAS revenues for the first quarter of 2011 amounted to $21.3 million, compared to $24.6 million for the same period last year. The year over year decline in MVAS revenues was primarily due to China Mobile implementing a series of measures in late 2009 and early 2010.

　　Gross margin for the first quarter of 2011 was 53%, down from 57% for the same period last year. Advertising gross margin for the first quarter of 2011 was 54%, compared to 56% for the same period last year. Non-GAAP advertising gross margin for the first quarter of 2011 was 55%, compared to 58% for the same period last year. The decline in non-GAAP advertising gross margin was due to higher spending in bandwidth and content, mostly related to our microblog Weibo and video initiatives. MVAS gross margin for the first quarter of 2011 was 39%, compared to 49% for the same period last year. The decline in MVAS gross margin was primarily due to product mix and increased revenue sharing with MVAS partners.

　　Operating expenses for the first quarter of 2011 totaled $41.8 million, compared to $33.5 million for the same period last year. Non-GAAP operating expenses for the first quarter of 2011 were $39.1 million, compared to $27.8 million for the same period last year. The increase in non-GAAP operating expenses was primarily due to higher personnel-related expenses and increased marketing expenditures in connection with our Weibo product.

　　Operating income for the first quarter of 2011 was $11.5 million, compared to $14.6 million for the same period last year. Non-GAAP operating income for the first quarter of 2011 was $10.1 million, compared to $16.7 million for the same period last year.

　　Non-operating income for the first quarter of 2011 was $5.0 million, compared to $11.6 million for the same period last year. The decrease in non-operating income mainly related to a $7.2 million gain SINA recognized in the first quarter of 2010, which represented its portion of a gain China Real Estate Information Corporation (“CRIC”), its investee company, recognized from the acquisition of China Online Housing Technology Corporation (“COHT”). Non-GAAP equity income from CRIC, which is recorded one quarter in arrears, was $5.9 million for the first quarter of 2011 and for the comparable period last year.

　　Provision for income taxes for the first quarter of 2011 was $1.7 million, compared to $1.9 million for the same period last year.

　　Net income attributable to SINA for the first quarter of 2011 was $15.0 million, compared to $24.4 million for the same period last year. The year over year decrease in net income attributable to SINA was owing to increased marketing and engineering expenses related to our Weibo and video initiatives. Diluted net income per share attributable to SINA for the first quarter of 2011 was $0.23, compared to $0.37 for the same period last year. Non-GAAP net income attributable to SINA for the first quarter of 2011 was $16.9 million, compared to $22.3 million for the same period last year. Non-GAAP diluted net income per share attributable to SINA for the first quarter of 2011 was $0.25, compared to $0.34 for the same period last year.

　　As of March 31, 2011, SINA’s cash, cash equivalents and short-term investments totaled $830.5 million, compared to $882.8 million as of December 31, 2010. The decrease in cash balance was mainly due to acquiring approximately 19% interest in Mecox Lane Limited as described in the Investment section below. Cash flow from operating activities for the first quarter of 2011 was $21.9 million, compared to $18.2 million for the same period last year. Subsequent to December 31, 2010, the Company issued approximately 3.7 million new ordinary shares to settle conversion requests equivalent to $96.1 million in convertible bonds.

　　Investment

　　In March 2011, the Company purchased 77.0 million ordinary shares (equivalent to 11.0 million American Depositary Shares or ADSs), or approximately 19% of Mecox Lane’s issued and outstanding shares (the “Purchase Shares”) of Mecox Lane Limited (“Mecox Lane”) for an aggregate purchase price of $66.0 million, or $0.8571 per share, equivalent to $6.00 per ADS (the “Mecox Lane Transaction”). The Company has the right to nominate one member to Mecox Lane’s board of directors. The Purchase Shares are subject to a one-year lock-up starting from the closing date of the Mecox Transaction on March 25, 2011. The Company also has a two-year option from the closing date to purchase an additional 48.3 million ordinary shares (equivalent to 6.9 million ADS) of Mecox Lane with an exercise price of $1.1429 per share, equivalent to $8.00 per ADS.

　　Business Outlook

　　SINA estimates that its non-GAAP net revenues for the second quarter of 2011 will be between $112 million and $115 million, with advertising revenues to be between $90 million and $92 million and non-GAAP non-advertising revenues to be between $22 million and $23 million. Non-GAAP net revenues and non-GAAP non-advertising revenues exclude the recognition of $4.7 million in deferred license revenue related to SINA’s equity investment in CRIC.

　　Non-GAAP Measures

　　This release contains financial measures that are not prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). These non-GAAP financial measures, which are used as measures of SINA’s performance, should be considered in addition to, not as a substitute for, measures of the Company’s financial performance prepared in accordance with GAAP. The Company’s non-GAAP financial measures may be defined differently than similar terms used by other companies. Accordingly, care should be exercised in understanding how the Company defines its non-GAAP financial measures.

　　Reconciliations of the Company’s non-GAAP measures to the nearest GAAP measures are set forth in the section below titled “Unaudited Reconciliation of Non-GAAP to GAAP Results.” These non-GAAP measures include non-GAAP net revenues, non-GAAP gross profit, non-GAAP advertising gross margin, non-GAAP operating expenses, non-GAAP income from operations, non-GAAP net income (loss) attributable to SINA and non-GAAP diluted net income (loss) per share attributable to SINA.

　　The Company’s management uses non-GAAP financial measures to gain an understanding of the Company’s comparative operating performance (when comparing such results with previous periods or forecasts) and future prospects. The Company’s non-GAAP financial measures exclude certain items, including stock-based compensation, amortization of intangible assets, recognition of deferred revenues and gain/loss resulting from the disposal, purchase or impairment of a business, investment or non-controlling interest in a subsidiary from its internal financial statements for purposes of its internal budgets. Non-GAAP financial measures are used by the Company’s management in their financial and operating decision-making, because management believes they reflect the Company’s ongoing business in a manner that allows meaningful period-to-period comparisons. The Company’s management believes that these non-GAAP financial measures provide useful information to investors and others in the following ways: 1) in comparing the Company’s current financial results with the Company’s past financial results in a consistent manner, and 2) in understanding and evaluating the Company’s current operating performance and future prospects in the same manner as management does, if they so choose. The Company’s management further believes the non-GAAP financial measures provide useful information to both management and investors by excluding certain expenses, gains/losses and other items (i) that are not expected to result in future cash payments or (ii) that are non-recurring in nature or may not be indicative of its core operating results and business outlook.

　　The Company’s management believes excluding stock-based compensation from its non-GAAP financial measures is useful for itself and investors, as such expense will not result in future cash payment and is not an indicator used by management to measure the Company’s core operating results and business outlook.

　　The Company’s management believes excluding the amortization expense of intangible assets from its non-GAAP financial measures is useful for itself and investors, because it enables a more meaningful comparison of the Company’s cash performance between reporting periods. In addition, such charges will not result in cash settlement in the future and is not an indicator used by management to measure the Company’s core operating results and business outlook.

　　The Company’s management believes excluding the recognition of deferred revenues, mostly relating to the license agreements resulting from SINA injecting its online real estate advertising business into its majority-owned subsidiary COHT and exchanging its interest in COHT for approximately 33% interest in CRIC upon the successful listing of CRIC on the NASDAQ Global Select Market in October 2009, from its non-GAAP financial measures is useful for itself and investors, because it enables a more meaningful comparison of the Company’s revenue performance between reporting periods. In addition, such revenues will not result in cash settlement in the future and is not an indicator used by management to measure the Company’s core operating results and business outlook.

　　The Company’s non-GAAP equity income from its interest in net income attributable to CRIC excludes stock-based compensation, amortization expense of intangible assets and gains from the purchase of a business, which are consistent with the Company’s adjusted items to calculate non-GAAP measures.

　　The Company’s management believes excluding gain/loss resulting from the disposal, purchase or impairment of a business, investment or non-controlling interest in a subsidiary from its non-GAAP financial measure of net income attributable to SINA is useful for itself and investors, because such gains/losses are not indicative of the Company’s core operating results.

　　The non-GAAP financial measures have limitations. They do not include all items of income and expense that affect the Company’s operations. Specifically, these non-GAAP financial measures are not prepared in accordance with GAAP, may not be comparable to non-GAAP financial measures used by other companies and, with respect to the non-GAAP financial measures that exclude certain items under GAAP, do not reflect any benefit that such items may confer to the Company. Management compensates for these limitations by also considering the Company’s financial results as determined in accordance with GAAP.
