Fourth Quarter 2012 Financial Results

For the fourth quarter of 2012, SINA reported net revenues of $139.1 million, compared to $133.4 million for the same period last year.  Non-GAAP net revenues for the fourth quarter of 2012 totaled $134.4 million, compared to $128.7 million for the same period last year.

Online advertising revenues for the fourth quarter of 2012 were $110.7 million, compared to $103.7 million for the same period last year.  Non-advertising revenues for the fourth quarter of 2012 totaled $28.5 million, compared to $29.7 million for the same period last year.  Mobile value-added services (“MVAS”) revenues for the fourth quarter of 2012 decreased 38% year over year to $13.2 million, while the rest of non-GAAP non-advertising revenues grew 181% to $10.6 million, mainly from Weibo value added services (“VAS”).  As the market in China shifts towards mobile Internet, the Company expects to further reallocate its resources away from the low-margin MVAS business to Weibo VAS.

Gross margin for the fourth quarter of 2012 was 57%, compared to 54% for the same period last year.  Advertising gross margin for the fourth quarter of 2012 was 56%, the same as the corresponding period last year.  Non-GAAP advertising gross margin for the fourth quarter of 2012 was 57%, also the same as last year.  MVAS gross margin for the fourth quarter of 2012 was 45%, compared to 35% for the same period last year, due to a shift in product mix.

Operating expenses for the fourth quarter of 2012 totaled $73.8 million, compared to $66.7 million for the same period last year.  Non-GAAP operating expenses for the fourth quarter of 2012 were $69.0 million, compared to $62.3 million for the same period last year.  The increase in non-GAAP operating expenses was primarily due to higher personnel costs, lease expenses and infrastructure spending, which were partially offset by lower marketing expenditures.

Income from operations for the fourth quarter of 2012 was $5.6 million, compared to $6.0 million for the same period last year.  Non-GAAP income from operations for the fourth quarter of 2012 was $6.4 million, compared to $6.7 million for the same period last year.

Non-operating loss from for the fourth quarter of 2012 was $2.1 million, compared to a non-operating income of $3.8 million from the same period last year.  Non-operating loss in the fourth quarter of 2012 included $4.4 million in losses from equity investments, or $0.4 million in losses on a non-GAAP basis, which were accounted for under the equity-method accounting and reported on a one-quarter lagging basis.

Net income attributable to SINA for the fourth quarter of 2012 was $2.4 million, compared to $9.3 million for the same period last year.  Diluted net income per share attributable to SINA for the fourth quarter of 2012 was $0.03, compared to $0.14 for the same period last year.  Non-GAAP net income attributable to SINA for the fourth quarter of 2012 was $9.0 million, compared to $14.0 million for the same period last year.  Non-GAAP diluted net income per share attributable to SINA for the fourth quarter of 2012 was $0.13, compared to $0.21 for the same period last year.

As of December 31, 2012, SINA’s cash, cash equivalents and short-term investments totaled $713.6 million, compared to $673.5 million as of December 31, 2011.  For the fourth quarter of 2012, cash provided by operating activities was $33.5 million, capital expenditures totaled $17.9 million and depreciation expenses amounted to $7.5 million.

Business Outlook

SINA estimates that its non-GAAP net revenues for the first quarter of 2013 will be between $115 million and $119 million, including advertising revenues to be between $94 million and $96 million, and non-GAAP non-advertising revenues to be between $21 million and $23 million.  Non-GAAP net revenues and non-GAAP non-advertising revenues exclude the recognition of $4.7 million in deferred license revenues related to SINA’s equity investment in E-House/CRIC.

Non-GAAP Measures

This release contains the following non-GAAP financial measures: non-GAAP net revenues, non-GAAP non-advertising revenues, non-GAAP advertising gross margin, non-GAAP gross profit, non-GAAP operating expenses, non-GAAP income/(loss) from operations, non-GAAP equity earnings/(loss) from equity investments, non-GAAP net income/(loss) attributable to SINA and non-GAAP diluted net income/(loss) per share attributable to SINA.  These non-GAAP financial measures should be considered in addition to, not as a substitute for, measures of the Company’s financial performance prepared in accordance with U.S. 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.”

The Company’s non-GAAP financial measures exclude certain items, including share-based compensation, amortization of intangible assets, recognition of deferred revenues and gain/loss resulting from the disposal, purchase or impairment of a business, investment or non-controlling interest in a subsidiary.  The Company’s management uses these non-GAAP financial measures in their financial and operating decision-making, because management believes these measures reflect the Company’s ongoing business operations in a manner that allows more meaningful period-to-period comparisons.  The Company believes that these non-GAAP financial measures provide useful information to investors and others in the following ways: (i) in comparing the Company’s current financial results with the Company’s past financial results in a consistent manner, and (ii) 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 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 the Company’s core operating results and business outlook.

Use of non-GAAP financial measures has limitations.  Our non-GAAP financial measures do not include all income and expense items that affect the Company’s operations.  They may not be comparable to non-GAAP financial measures used by other companies.  Management compensates for these limitations by also considering the Company’s financial results prepared in accordance with U.S. GAAP.
