　　GAAP net income was $8.6 million or $0.15 diluted net income per share, compared to $7.0 million or $0.12 diluted net income per share in the same period last year.

　　Non-GAAP net income* was $11.4 million or $0.19 diluted non-GAAP net income per share, compared to $9.6 million or $0.16 diluted non-GAAP net income per share in the same period last year.

　　*Non-GAAP measures are described below and reconciled to the corresponding GAAP measures in the section below entitled "Reconciliation of Non-GAAP to GAAP Results."

　　"We are very pleased with another quarter of solid financial and operational performance. Our online advertising revenues in the first quarter continue to be strong with our advertising revenues in China having grown 45% or more year over year for the fourth consecutive quarter," said Charles Chao, CEO of SINA. "On the operational front, we believe that we have made measurable gains in transforming SINA into a multimedia content platform with strong user participation and sticky interactive community."

　　Financial Results

　　For the first quarter of 2007, SINA reported total revenues of $51.3 million, compared to $46.7 million in the same period in fiscal 2006 and $56.4 million for the fourth quarter of 2006.

　　Advertising revenues for the first quarter of 2007 totaled $31.8 million, representing a 43% increase from the same period last year and an 11% decrease from last quarter. Advertising revenues in China grew 45% year over year to $30.9 million for the first quarter of 2007. The quarter over quarter decrease in advertising revenues was mainly due to seasonality, as the first quarter historically has been the Company's weakest quarter for advertising revenues. Advertising revenues in the first quarter of 2007 represented 62% of total revenues, up from 47% in the same period last year.

　　Non-advertising revenues for the first quarter of 2007 totaled $19.5 million, a 20% decrease from the same period in 2006 and a 6% decrease from the previous quarter.

　　MVAS revenues for the first quarter of 2007 were $18.2 million, declining 20% from the same period last year and declining 5% from last quarter. Revenues from interactive voice response ("IVR") declined 32% quarter over quarter to $3.5 million. During the first quarter of 2007, the Company began placing less emphasis on promoting IVR due to an increase in operator costs for IVR. As a result of switching from the Company's proprietary IVR platform to China Mobile's IVR platform, operator costs for IVR increased from 15% to 30%. SMS revenues decreased 1% sequentially to $10.6 million, while revenues from 2.5G products, including multimedia messaging service ("MMS"), wireless application protocol ("WAP") and Kjava, increased 32% quarter over quarter to $3.2 million.

　　Other non-advertising revenues, mainly search and other fee-based revenues, were $1.3 million for the first quarter of 2007, representing a decline of 31% from the same period last year and 7% from last quarter. The decline in other non-advertising revenues was mainly due to the continued phasing out of the prior search business.

　　Gross margin for the first quarter of 2007 was 59%, down from 61% in the same period last year and 62% in the last quarter. Advertising gross margin for the first quarter of 2007 was 58%, compared to 63% in the same period last year and 65% in the previous quarter. Advertising gross margin in the first quarter of 2007 included stock-based compensation, which was equivalent to 1% of advertising revenues. Excluding this item, advertising gross margin in the first quarter of 2007 was 59%, compared to 64% in the same period last year and 66% in the previous quarter. The decrease in advertising gross margin was mainly due to the increase in bandwidth cost to support the roll-out of SINA Podcasting and other Web 2.0 products. Other factors contributing to the year over year decline in advertising gross margin included increased content and web production costs. On a sequential basis, a lower revenue base in the first quarter of 2007 also contributed to the decline in advertising gross margin. MVAS gross margin for the first quarter of 2007 was 60%, compared to 59% in the same period last year and 61% last quarter.

　　Operating expenses for the first quarter of 2007 totaled $22.9 million, an increase of 4% from the same period last year and a decline of 7% from last quarter. Non-GAAP operating expenses for the first quarter of 2007, which exclude stock-based compensation and amortization expense of intangible assets, was $20.8 million, representing a 2% increase from the same period last year and a decline of 7% from last quarter. The year over year increase in operating expenses primarily relates to the appreciation of RMB against the dollar and higher bad debt expenses, partially offset by a decrease in payroll-related costs and marketing expenses. The quarter over quarter decrease in operating expenses was primarily due to lower commissions and other payroll-related costs and lower travel and entertainment expenses, partially offset by higher bad debt expenses.

　　Net income for the first quarter of 2007 was $8.6 million or $0.15 diluted net income per share, compared to $7.0 million or $0.12 diluted net income per share for the same period last year. Non-GAAP net income for the first quarter of 2007 was $11.4 million or $0.19 diluted non-GAAP net income per share, compared to $9.6 million or $0.16 diluted non-GAAP net income per share for the same period last year.

　　As of March 31, 2007, SINA's cash, cash equivalents and investments in marketable securities totaled $382.7 million, compared to $304.4 million and $362.8 million as of March 31, 2006 and December 31, 2006, respectively. Cash flow from operating activities for the first quarter of 2007 was $16.6 million, compared to $12.5 million for the same period last year and $14.9 million last quarter.

　　Business Outlook

　　The Company estimates its total revenues for the second quarter of 2007 to be between $58.0 million and $60.0 million, with advertising revenues to be between $40.0 million and $41.0 million and non-advertising revenues to be between $18.0 million and $19.0 million. Stock-based compensation for the second quarter of 2007 is expected to be approximately $2.0 million, which excludes any new shares that may be granted.

　　Non-GAAP Measures

　　This release contains non-GAAP financial measures. These non-GAAP financial measures, which are used as measures of the Company'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 "Reconciliation of Non-GAAP to GAAP Results." These non-GAAP measures include non-GAAP gross profit, non-GAAP operating expenses, non-GAAP income from operations, non-GAAP net income, non-GAAP diluted net income per share 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 special items, including stock-based compensation charges, write off of prepaid license fees, amortization of intangible assets, amortization of convertible debt issuance cost, gain and loss on the sale of business and investments, and gain and loss on investments, 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 understanding and evaluating the Company's current operating performance and future prospects in the same manner as management does, if they so choose, and 2) in comparing in a consistent manner the Company's current financial results with the Company's past financial results. The Company's management further believes the non-GAAP financial measures provide useful information to both management and investors by excluding certain expenses, gains and losses (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 otherwise unrelated to the Company's core operating results.

　　The Company's management believes excluding the non-cash write off of prepaid license fees from its non-GAAP financial measures is useful for itself and investors as such expense does not impact cash earnings and is not indicative of the Company's core operating results and business outlook.

　　The Company's management believes excluding the non-cash amortization expense of intangible assets resulting from business acquisitions from its non-GAAP financial measures of operating expenses, income from operations and net income and excluding the non-cash amortization expense of intangible assets resulting from equity-method investments from its non-GAAP financial measure of net income are 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.

　　The Company's management believes excluding non-cash amortization expense of issuance cost relating to convertible bonds from its non-GAAP financial measure of net income is useful for itself and investors as such expense does not have any impact on cash earnings.

　　The Company's management believes excluding gains and losses on the sale of a business and investments from its non-GAAP financial measure of net income is useful for itself and investors because such gains and losses are not indicative of the Company's core operating results.

　　The Company's management believes excluding gains and losses on investment from its non-GAAP financial measure of net income is useful for itself and investors because the Company does not typically invest in common stock of other companies. Therefore, these charges are otherwise unrelated to the Company's ongoing business operations.

　　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.
