Financial Results
For the quarter ended September 30, 2004, SINA reported record net revenues of $52.5 million, an increase of 64.5% from $31.9 million reported in the same period in 2003 and an increase of 6.7% from $49.2 million reported in the previous quarter, beating the Company’s guidance of between $49.0 million and $50.0 million.

Advertising revenues totaled $18.5 million for the quarter, representing a 61.8% increase over $11.4 million reported in the same period in 2003 and a 19.4% increase over $15.5 million reported in the previous quarter.

Non-advertising revenues totaled $34.0 million for the quarter, a 66.0% increase over $20.5 million reported in the same period in 2003 and a 1.0% increase over $33.7 million reported in the previous quarter. Total revenues from mobile value-added services were $31.3 million, representing an increase of 72.5% from $18.1 million reported in the same period in 2003 and of 0.5% from $31.1 million reported in the previous quarter.

For the third quarter, SINA continued to benefit from its diversified product offerings in mobile value-added service. Revenues from 2.5G (MMS and WAP) products, IVR and other new services grew approximately 37.0% from $5.1 million or 16.3% of total mobile

value-added service revenues for the second quarter to $7.0 million or 22.2% of total mobile value-added service revenues for the third quarter. During the quarter, the Company’s IVR service was temporarily suspended by China Mobile due to the violation of certain operating procedures. Excluding the effect of the IVR service, revenues from 2.5G products and other new mobile value-added service revenues for the third quarter grew by 77.6% from the previous quarter. On the other hand, revenues from SMS declined another 6.6% from $26.0 million for the second quarter to $24.3 million for the third quarter. On October 15, 2004, SINA’s IVR service was resumed by China Mobile.

The gross margin for the quarter was 67.9%, down from 70.9% reported in the previous quarter and from 70.0% reported in the same period in 2003. Gross margin for advertising revenues was approximately 61.4% for the third quarter, compared to 68.0% for the previous quarter. The decline in advertising gross margin was largely due to $1.1 million revenue share paid to an exclusive Olympic content partner associated with China Olympic Committee. Excluding this revenue share payment and some other one-time content purchases relating to Olympic coverage, advertising gross margin would have been unchanged from the previous quarter. Gross margin for mobile value-added service revenues for the third quarter was 70.0% as compared to 70.8% for the previous quarter. The slight decline in mobile value-added service gross margin was a result of increased transmission cost paid to mobile operators with the increase in usage- based services.

Operating expenses for the third quarter totaled $18.8 million, an increase of 74.4% from $10.8 million reported in same period of 2003 and an increase of 16.8% over $16.1 million reported in the previous quarter. Excluding the amortization of intangible assets, pro forma operating expenses for the third quarter totaled $17.7 million, an increase of 72.8% over $10.3 million reported in the same period of 2003 and an increase of 17.1% over $15.2 million reported in the previous quarter. The sequential increase in pro forma operating expenses was mainly due to an additional $1 million marketing expenditure relating to the Olympic event, an increase in advertising expenses relating to mobile value-added services and an increase in product development cost with the addition of instant messaging operation as a result of the acquisition of UC instant messaging platform as well as the launch of the casual game portal iGame.

Net income for the third quarter was $14.5 million, representing an increase of 24.4% from a net income of $11.7 million for the same period in 2003 and a decrease of 19.5% from a net income of $18.0 million for the previous quarter. Diluted net income per share was $0.27 for the quarter, compared to a diluted net income per share of $0.21 for the same period of 2003 and a diluted net income per share of $0.31 for the previous quarter. During the third quarter, the Company recorded a gain of approximately $1.0 million from the sale of a minority interest investment and a write-off of approximately $2.7 million for its investment in Sun Media Group. The net investment loss was $1.7 million.

On a pro forma basis, net income for the third quarter totaled $17.4 million, compared to a pro forma net income of $12.3 million for the same period in 2003 and of $19.1 million for

the previous quarter. Diluted net income per share, on a pro forma basis, was $0.32 for the quarter, compared to a pro forma diluted net income per share of $0.21 for the same period of 2003 and of $0.33 for the previous quarter, above the range of the Company’s guidance of between $0.29 and $0.30 per share. Pro forma net income excludes non-cash charges relating to amortization of intangible assets, stock based compensation, convertible bond issuance cost, gain or loss from Sun Media Group investment and other one-time investment gains or losses.

As of September 30, 2004, SINA’s cash, cash equivalents and investments in marketable securities totaled $243.6 million, an increase of $0.6 million from three months ago. Cash flow from operating activities for the third quarter was $10.8 million, compared to $14.0 million for the previous quarter and $13.7 million for the same period in 2003. The sequential decline in cash flows from operating activities was primarily due to an increase in accounts receivable balance from $29.6 million at June 30, 2004 to $42.9 million at September 30, 2004. Accounts receivable from mobile operators for mobile value-added services increased by approximately $7.9 million for the quarter as certain provincial mobile operators delayed payments to all wireless service providers pending account reconciliations during the quarter. The Company however has received a majority of these delayed payments after the end of the third quarter. Total payments received from mobile operators after the quarter end and up to October 26 were approximately $8.0 million. In addition, accounts receivable relating to advertising business also increased by $5.4 million from the previous quarter. The increase in advertising related accounts receivable was largely due to the increase in gross advertising revenues as well as the seasonality for collection.

Olympics
During the quarter, SINA was able to capitalize on the singular event of 2004, the 2004 Summer Olympics Games to further solidify its position and brand as the premier portal in China. The SINA Olympics Official Site with exclusive live video interviews of the Chinese gold medalists as well as real time updates on the various Olympic events became one of the most trafficked sites in China. According Nielsen/NetRatings, between August 13 and August 30, the SINA Olympics Site was visited by 28 million unique visitors. In addition to the portal, SINA was able to leverage the event to market its mobile services and further cement various content and marketing relationships with many of its key partners.

Online Game
In late August, SINA through its joint venture with NcSoft commenced the open beta test of Lineage 2 game. To date, Lineage 2 has been deployed in 12 regional telecom data centers to service game players throughout China. From October 1 through October 26, the daily average concurrent user count is roughly 120,000. Lineage 2 has entered into its final stage of open beta test and the Company expects to commence commercial operation in mid November.

SINA’s casual game portal iGame has obtained 3.6 million users to date since its launch in July. The casual game portal now offers 23 casual games, 7 of which are self-developed by SINA.

Acquisition
In July 2004, SINA announced its agreement to acquire Davidhill Capital Inc. and its UC instant messaging technology platform. Launched in 2002, the UC instant messaging service allows users to communicate in real-time over the Internet and mobile phone networks, via text messages, images and voice. UC also provides community services such as chat rooms, online games, alumni clubs, online karaoke and other entertainment services. Based on a highly scalable technology platform, the UC instant messaging service has approximately 80 million registered user accounts and approximately 200,000 peak simultaneous online user accounts. The acquisition was closed in October 2004. SINA paid approximately $12.6 million in cash and approximately 64,000 SINA ordinary shares valued at $2.4 million as the first installment payment. SINA will pay up to an additional $21 million in cash and shares in the 12 months if certain simultaneous online user targets are reached. As a result of the acquisition, the Company recorded certain intangible assets in the amount of $10.8 million, which will be amortized over periods ranging from 27 months to 10 years. The amortization expense related to these intangible assets amounted to $0.3 million for the third quarter. In addition, the Company recorded goodwill in the amount of $4.3 million for this acquisition. The operating results of Davidhill Capital have been consolidated starting July 1, 2004 when SINA took over the effective control of the company.

Business Outlook
The Company estimates that its total revenues for Q4 2004 to be between $54.5 million and $55.5 million, with advertising revenues between $18.5 million and $19.0 million and non-advertising revenues between $36.0 million and $36.5 million. Pro forma net income is expected to be between $18.5 million and $19.0 million for Q4 2004.

NON-GAAP Measures
To supplement the consolidated financial statements presented in accordance with GAAP, SINA uses non-GAAP measures of gross profit, operating income, net income and earnings per share, which are adjusted from results based on GAAP to exclude certain expenses, gains and losses. These non-GAAP measures are provided to enhance the user’s overall understanding of our current financial performance and our prospects for the future. Specifically, the Company believes the non-GAAP results provide useful information to both management and investors by excluding certain expenses that are not expected to result in future cash payments, gains and losses that are non-recurring in nature or may not be indicative of our core operating results. In addition, because the Company has historically reported certain non-GAAP results to investors, the Company believes the inclusion of non-GAAP measures provides consistency in our financial reporting. These measures should be considered in addition to results prepared in accordance with generally accepted accounting principles, but should not be considered a substitute for or superior to GAAP results. Consistent with the Company’s historical practice, the non-GAAP measures included in this press release have been reconciled to the nearest GAAP measure.
