SHANGHAI, China—August 4, 2010—SINA Corporation (NASDAQ GS: SINA), a leading online media company and mobile value-added service (“MVAS”) provider for China and for the global Chinese communities, today announced its unaudited financial results for the quarter ended June 30, 2010.

　　Starting in the fourth quarter of 2009, in addition to the disclosure of GAAP results below, SINA’s historical revenues and certain non-GAAP measures (namely, gross profit, operating expenses, income from operations and advertising gross margin) have been revised to exclude results from China Online Housing Technology Corporation (“COHT”), adjusted for the impact of the amended and restated advertising agency agreement on a pro forma basis as if the agreement had been effective at the beginning of the periods presented. These adjustments were made to reflect 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 China Real Estate Information Corporation (“CRIC”) upon the successful listing of CRIC on the NASDAQ Global Select Market in October 2009 (“Transaction”). Non-GAAP measures are described below and reconciled to the corresponding GAAP measures in the section below titled “Unaudited Reconciliation of Non-GAAP to GAAP Results.”

　　Second Quarter 2010 Highlights

　　•Net revenues grew 10% year over year to $99.4 million.

　　•Non-GAAP net revenues grew 18% year over year to $94.7 million, exceeding SINA’s guidance between $90.0 million and $93.0 million.

　　•Advertising revenues grew 27% year over year to $73.1 million.

　　•Non-GAAP advertising revenues grew 52% year over year to $73.1 million, exceeding SINA’s guidance between $70.0 million and $72.0 million.

　　•Non-advertising revenues decreased 19% year over year to $26.3 million.

　　•Non-GAAP non-advertising revenues decreased 33% year over year to $21.6 million, but exceeded SINA’s guidance between $20.0 million and $21.0 million.

　　•Net income attributable to SINA increased 89% year over year to $25.2 million, or $0.38 diluted net income per share attributable to SINA.

　　•Non-GAAP net income attributable to SINA increased 62% year over year to $27.7 million, or $0.42 non-GAAP diluted net income per share attributable to SINA.

　　“SINA had an outstanding second quarter. Our online advertising business, which excludes the adjusted results of SINA real estate advertising, grew 52% year over year, contributing to SINA’s top line and bottom line growth. SINA’s ability to rapidly grow online advertising revenues while expanding our profit margin is a reflection of the strength of SINA’s brand, market influence and online media capabilities,” said Charles Chao, CEO of SINA. “The adoption of SINA Weibo, our Twitter-like miniblog, is strong and increasingly gaining momentum, which is adding excitement to SINA’s brand and extending SINA’s leadership position in China’s online media space.”

　　Financial Results

　　For the second quarter of 2010, SINA reported net revenues of $99.4 million, compared to $90.3 million for the same period last year. Non-GAAP net revenues for the second quarter of 2010 totaled $94.7 million, compared to $80.6 million for the same period last year. Advertising revenues for the second quarter of 2010 were $73.1 million, compared to $57.8 million for the same period last year. Non-GAAP advertising revenues for the second quarter of 2010 were $73.1 million, compared to $48.1 million for the same period last year. The year over year advertising revenue growth was partially boosted by a successful coverage of the 2010 World Cup.

　　Non-advertising revenues for the second quarter of 2010 totaled $26.3 million, compared to $32.5 million for the same period last year. MVAS revenues for the second quarter of 2010 amounted to $20.0 million, compared to $30.9 million for the same period last year. The year over year decline in MVAS revenues was primarily due to China Mobile implementing series of measures in late November 2009 and January 2010, including the suspension of billing of wireless application protocol (“WAP”), limiting service offerings and partnerships allowed for each short messaging service (“SMS”) code, preventing television and radio promotion of certain interactive voice response system (“IVR”) products and requiring additional notices and customer confirmations in the MVAS ordering process. Other non-advertising revenues for the second quarter of 2010 included amortized deferred revenue of $4.7 million relating to the license agreements resulting from the Transaction.

　　Gross margin for the second quarter of 2010 was 58%, up from 56% for the same period last year. Advertising gross margin for the second quarter of 2010 was 60%, up from 58% for the same period last year. Non-GAAP advertising gross margin for the second quarter of 2010 was 61%, compared to 55% for the same period last year. The increase in non-GAAP advertising gross margin was mostly due to revenues growing faster than advertising cost of revenues. MVAS gross margin for the second quarter of 2010 was 42%, compared to 50% for the same period last year. The decline in MVAS gross margin was primarily due to a decline in mobile revenues without a proportional decline in mobile costs.

　　Operating expenses for the second quarter of 2010 totaled $32.0 million, compared to $36.7 million for the same period last year. Operating expenses for the second quarter of 2010 included $2.6 million in stock-based compensation expenses and $0.2 million in amortization expenses of intangible assets. Non-GAAP operating expenses for the second quarter of 2010 were $29.1 million, compared to $30.9 million for the same period last year. General and administrative expenses for the second quarter of 2010 included a reversal of $1.6 million in allowance for bad debt, resulting from the receipt of payments for past due accounts receivable. The decrease in non-GAAP operating expenses was also due to lower marketing expenditures, partially offset by higher personnel-related expenses.

　　Operating income for the second quarter of 2010 was $26.1 million, compared to $13.6 million for the same period last year. Non-GAAP operating income for the second quarter of 2010 was $25.0 million, compared to $12.4 million for the same period last year.

　　The Company accounts for its investment in CRIC using the equity method of accounting and reports its interest in CRIC one quarter in arrears. Equity loss from CRIC for the second quarter of 2010 was $0.1 million, which is based on the Company’s share of net income attributable to CRIC for the first quarter of 2010 less its share of amortization of CRIC’s intangibles not on CRIC’s books. On a non-GAAP basis, equity income from CRIC for the second quarter of 2010 was $3.4 million, which was calculated based on non-GAAP net income attributable to CRIC following the same non-GAAP financial measures as the Company.

　　Provision for income taxes for the second quarter of 2010 was $2.4 million, compared to $2.0 million for the same period last year.

　　Net income attributable to SINA for the second quarter of 2010 was $25.2 million, compared to $13.3 million for the same period last year. Diluted net income per share attributable to SINA for the second quarter of 2010 was $0.38, compared to $0.23 for the same period last year. Non-GAAP net income attributable to SINA for the second quarter of 2010 was $27.7 million, compared to $17.1 million for the same period of last year. Non-GAAP diluted net income per share attributable to SINA for the second quarter of 2010 was $0.42, compared to $0.29 for the same period last year.

　　As of June 30, 2010, SINA's cash, cash equivalents and short-term investments totaled $828.2 million, compared to $821.5 million as of December 31, 2009. Cash flow from operating activities was $12.9 million for the second quarter of 2010, compared to $18.8 million for the same period last year.

　　Business Outlook

　　SINA estimates that its non-GAAP net revenues for the third quarter of 2010 to be between $101.0 million and $104.0 million, with non-GAAP advertising revenues to be between $80.0 million and $82.0 million and non-GAAP non-advertising revenues to be between $21.0 million and $22.0 million. Non-GAAP net revenues and non-GAAP non-advertising revenues exclude the recognition of $4.7 million in deferred revenue, which is related to the license agreements resulting from the Transaction.

　　Non-GAAP Measures

　　This release contains non-GAAP financial measures. 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 United States Generally Accepted Accounting Principles (“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 revenues, non-GAAP gross profit, non-GAAP operating expenses, non-GAAP income from operations, non-GAAP net income attributable to SINA, non-GAAP diluted net income per share attributable to SINA, and non-GAAP advertising gross margin.

　　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, gain/loss on the disposal/purchase of business and investment, recognition of deferred revenues relating to the license agreements resulting from the Transaction and COHT’s adjusted results (for certain non-GAAP measures) 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 they enable 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 gain/loss on the disposal/purchase of a business or investment 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 Company’s management believes excluding the recognition of deferred revenues relating to the license agreements resulting from the Transaction from its non-GAAP financial measures is useful for itself and investors, because they enable 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 management believes excluding COHT’s results, adjusting for the impact of the amended and restated advertising agency agreement on a pro forma basis as if the agreement had been effective at the beginning of the periods presented, from its non-GAAP financial measures to reflect the spin off of COHT is useful for itself and investors, because they enable management and investors to gain a better understanding of the Company’s comparative operating performance (when comparing such results with the current period or forecasts) and future prospects.

　　The Company’s non-GAAP equity income from its interest in net income attributable to CRIC exclude 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 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.
