Our focus on the online media business has led to enhanced brand recognition, strong user and traffic growth, and an impressive 44% year-over-year increase in online advertising revenues in China.

Financial Results

-1-

For the fourth quarter of 2006, SINA reported net revenues of $56.4 million, compared to $52.0 million in the same period in fiscal 2005 and $56.1 million for the third quarter of 2006. Advertising revenues for the fourth quarter of 2006 totaled $35.7 million, representing a 43% increase from the same period last year and a 9% increase from last quarter. The growth in advertising came mainly from China, which recorded advertising revenues of $35.0 million for the fourth quarter of 2006, representing an increase of 45% from the same period last year and 10% sequentially. The growth in advertising revenues can be mostly attributed to the Beijing Auto Show, advertising seasonality and the momentum generated from the World Cup earlier in the year. Advertising revenues in the fourth quarter of 2006 represented 63% of total revenues, up from 48% in the same period last year.

Non-advertising revenues for the fourth quarter of 2006 totaled $20.7 million, a 23% decrease from the same period in 2005 and a 12% decrease over the previous quarter. The decrease in non-advertising revenues came mostly from the decline in MVAS revenues, which recorded $19.3 million for the fourth quarter of 2006, representing a decline of 22% from the same period in 2005 and a decline of 11% from last quarter. The decline in MVAS revenues was primarily due to the changes in operator policy announced in July 2006. SMS revenues contributed to most of the year-over-year decline in MVAS revenues, dropping 41% year-over-year to $10.8 million in the fourth quarter of 2006. This was partially offset by IVR revenues, which grew 158% year-over-year to $5.1 million, or 26% of total MVAS revenues, in the fourth quarter of 2006.

For fiscal 2006, SINA reported net revenues of $212.9 million, compared to $193.6 million in 2005. Advertising revenues for fiscal 2006 totaled $120.1 million, an increase of 41% from 2005. The growth in advertising came mostly from China, which generated $116.9 million in advertising revenues for fiscal 2006, representing a year-over-year growth of 44%. Non-advertising revenues for fiscal 2006 amounted to $92.8 million, a decrease of 15% from 2005. The decline in non-advertising revenues came mostly from MVAS, which generated $86.3 million in revenues for fiscal 2006, representing a 12% year-over-year decline.

Gross margin for the fourth quarter of 2006 was 62%, down from 66% in the same period last year and 64% in the last quarter. Gross margin for the fourth quarter of 2006 included a $1.1 million, or 2% of total revenues, write-off of prepaid license fees related to the iGame business, based on management’s assessment of the game business during the quarter. Advertising gross margin for the fourth quarter of 2006 was 65%, compared to 69% in the same period last year and 65% in the previous quarter. Advertising gross margin in the fourth quarter of 2006 included stock-based compensation, which was equivalent to 1% of advertising revenues. Excluding this item, advertising gross margin in the fourth quarter of 2006 was 66%, compared to 69% in the same period last year. The decline in gross margin can be mainly attributed to the increase in web production and bandwidth costs. MVAS gross margin for the fourth quarter of 2006 was 61%, compared to 62% for the same period in 2005 and last quarter.

Gross margin for fiscal 2006 was 63%, down from 67% from fiscal 2005. Advertising gross margin for fiscal 2006 was 65%, compared to 67% for fiscal 2005. Advertising gross margin in fiscal 2006 includes $1.7 million in stock-based compensation or 1% of advertising revenues. MVAS gross margin for fiscal 2006 was 60%, compared to 66% in the prior year. The decrease in gross margin was primarily related to higher transmission and content costs.

Operating expenses for the fourth quarter of 2006 totaled $24.5 million, an increase of 5% from the same period last year. Operating expenses for the fourth quarter of 2006 include $1.8 million in stock-based compensation and $0.4 million in amortization expense of intangible assets, while the operating expenses for the fourth quarter of 2005 include $0.5 million in amortization expense of intangible assets. Excluding these items, operating expenses for the fourth quarter of 2006 were $22.4 million, a decline of 2% from the fourth quarter of 2005. The decline was mainly due to lower marketing expenses.

Operating expenses for fiscal 2006 were $98.5 million, an 11% increase from 2005. Operating expenses for fiscal 2006 include $7.7 million in stock-based compensation and $1.8 million in amortization expense of intangible assets, while operating expenses for fiscal 2005 include $3.2 million in amortization expense of intangible assets. Excluding these items, operating expenses for 2006 were $89.0 million, an increase of 4% from fiscal 2005. The year over year increase was mainly due to higher payroll-related expenses, such as management bonus and sales commissions, and higher bad debt expenses, partially offset by lower marketing expenses.

Net income for the fourth quarter of 2006 was $11.7 million or $0.20 diluted net income per share, compared to $13.8 million or $0.24 for the same period last year. Net income for the fourth quarter of 2006 includes $1.1 million write-off of prepaid license fees, while net income for the fourth quarter of 2005 includes a $2.6 million gain from the sale of an online auction joint venture, both of which were excluded in the non-GAAP results. Non-GAAP net income for the fourth quarter of 2006 was $15.2 million or $0.26 non-GAAP, compared to $12.4 million or $0.21 in the same period last year.

Net income for fiscal 2006 totaled $39.9 million or $0.69 diluted net income per share, compared to $43.1 million or $0.75 diluted net income per share in fiscal 2005. Non-GAAP net income for fiscal 2006 was $51.6 million or $0.88 non-GAAP diluted net income per share, compared to $46.4 million or $0.79 diluted net income per share for fiscal 2005.

As of December 31, 2006, SINA’s cash, cash equivalents and investments in marketable securities totaled $362.8 million, compared to $300.7 million and $345.3 million as of December 31, 2005 and September 30, 2006, respectively. Cash flow from operating activities for the fourth quarter of 2006 was $14.9 million, compared to $14.4 million for the same period last year. For fiscal 2006, cash flow from operating activities was $63.1 million, compared to $58.3 million for fiscal 2005.

Business Outlook

-3-

The Company estimates that its total revenues for the first quarter of 2007 will be between $48.0 million and $50.0 million, with advertising revenues to be between $31.0 million and $32.0 million and non-advertising revenues to be between $17.0 million and $18.0 million.

Based on unvested shares as of the end of 2006 and excluding any new shares that may be granted, the Company estimates its stock-based compensation for the first quarter of 2007 to be between $2.2 million to $2.4 million and for fiscal 2007 to be between $8.2 million and $9.2 million.

Excluding the impact of any new accounting standards or tax regulations, such as FIN 48 Accounting for Uncertainty in Income Taxes, which became effective for the Company on January 1, 2007, the Company expects its applicable effective tax rate for 2007 to be approximately 10%.

Management Promotions and Changes

The Company announced today that Tong Chen, Senior Vice President and Chief Editor, who has been with the Company since 1997, has been promoted to Executive Vice President and Chief Editor, and Hong Du, Vice President, Sales & Marketing, who has been with the Company since 1999, has been promoted to Senior Vice President, Sales & Marketing.

Separately, Benjamin Tsiang, Executive Vice President in charge of SINA international operations, has decided to resign from the Company for personal reasons. Mr. Tsiang has agreed to serve as Senior Advisor to the Company.

Change of Filing Status

The Company announced that, effective immediately, it will satisfy its reporting obligations under Section 13(a) of the U.S. Securities Exchange Act of 1934 by filing reports with the Securities and Exchange Commission (SEC) on form available for use by Foreign Private Issuers (“FPI”). SINA currently meets the requirements of an FPI as defined under the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended. As a result of the change announced today, after the completion of filings related to fiscal 2006, which include a report on Form 10-K and proxy statement, the Company will no longer file its periodic reports with the SEC on Form 10-K and Form 10-Q or current reports on Form 8-K. Instead, the Company will file its future annual reports, beginning with the report for the fiscal year ending December 31, 2007, on Form 20-F, and current reports on Form 6-K, which forms are applicable to FPIs.

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

-4-

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. Non-GAAP financial measures that exclude stock-based compensation also enhance the comparability of results against prior periods.

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

-5-

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.
