SHANGHAI, China—March 2, 2011—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 fourth quarter and fiscal year ended December 31, 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 (“CRIC Transaction”).

　　Fourth Quarter 2010 Financial Results

　　For the fourth quarter of 2010, SINA reported net revenues of $110.0 million, compared to $98.2 million for the same period last year.

Operating expenses for the fourth quarter of 2009 included $17.7 million in stock-based compensation, the majority of which related to the private equity financed shares issued to management and, to a lesser extent, related to accelerated vesting of certain restricted share units granted to key managers and employees to recognize their contribution in 2009.

In accordance with US GAAP, the Company reassessed its investment in CRIC in the fourth quarter of 2010 and recognized an other-than-temporary impairment charge of $128.6 million.

Equity income from CRIC for the fourth quarter of 2010 was $1.4 million, compared to no equity income from CRIC for the same period last year, as such item is reported one quarter in arrears.

Non-GAAP net revenues and non-GAAP non-advertising revenues exclude the recognition of $4.7 million in deferred license revenue related the CRIC 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, recognition of deferred revenues, COHT’s adjusted results (for certain non-GAAP measures) 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 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 the recognition of deferred revenues, mostly relating to the license agreements resulting from the CRIC 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 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.
