For the fourth quarter of 2020, Weibo’s total net revenues were $513.4 million, an increase of 10% compared to $468.1 million for the same period last year.

Advertising and marketing revenues for the fourth quarter of 2020 were $453.5 million, an increase of 12% compared to $405.9 million for the same period last year. Advertising and marketing revenues from key accounts (“KAs”) and small & medium-sized enterprises (“SMEs”) were $393.9 million, an increase of 7% compared to $368.1 million for the same period last year.

VAS revenues for the fourth quarter of 2020 were $59.9 million, a decrease of 4% year-over-year compared to $62.2 million for the same period last year, which was primarily resulted from the decrease of live streaming business, and was partially offset by the revenue contribution from the interactive entertainment company which was acquired and consolidated to the Company in November 2020.

Costs and expenses for the fourth quarter of 2020 totaled $331.8 million, an increase of 5% compared to $317.4 million for the same period last year. The increase was primarily due to higher personal-related cost and step-up in marketing spend, and was partially offset by decreased general and administrative expenses. Non-GAAP costs and expenses were $309.3 million, an increase of 3% compared to $299.2 million for the same period last year.

Income from operations for the fourth quarter of 2020 was $181.6 million, compared to $150.7 million for the same period last year. Operating margin was 35%, compared to 32% last year. Non-GAAP income from operations was $204.1 million, compared to $168.9 million for the same period last year. Non-GAAP operating margin was 40%, compared to 36% last year.

Non-operating loss for the fourth quarter of 2020 was $175.8 million, compared to a loss of $25.1 million for the same period last year. Non-operating loss for the fourth quarter of 2020 mainly included (i) a 92.5 million net loss from fair value change of investments, which is excluded under non-GAAP measures; (ii) a $94.2 million investment related impairment, which is excluded under non-GAAP measures; and (iii) a $9.5 million net interest and other income.

Income tax benefits were $25.3 million, compared to income tax expenses of $31.1 million for the same period last year. The income tax benefit was primarily due to the recognition of preferential tax treatment for certain of the Company’s PRC subsidiaries, as well as reverse of recognition of deferred tax liabilities in prior periods related to certain investments.

Net income attributable to Weibo for the fourth quarter of 2020 was $29.0 million, compared to $95.1 million for the same period last year.

Advertising and marketing revenues from KAs and SMEs were $1.33 billion, a decrease of 7% compared to $1.43 billion for 2019, which primarily resulted from the adverse impact of the Covid-19 pandemic on the overall advertising demand mainly in the first half of 2020.

VAS revenues for 2020 were $203.8 million, a decrease of 14% compared to $236.7 million for 2019, mainly due to the decrease of revenues from the live streaming business.

Costs and expenses for 2020 totaled $1.18 billion, compared to $1.17 billion for 2019. Non-GAAP costs and expenses were $1.11 billion, compared to $1.10 billion for 2019.

Net income attributable to Weibo for 2020 was $313.4 million, compared to $494.7 million for 2019. Diluted net income per share attributable to Weibo for 2020 was $1.38, compared to $2.18 for 2019.

Non-GAAP Financial Measures

This release contains the following non-GAAP financial measures: non-GAAP costs and expenses, non-GAAP income from operations, non-GAAP net income attributable to Weibo, non-GAAP diluted net income per share attributable to Weibo and adjusted EBITDA. 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 exclude stock-based compensation, amortization of intangible assets, net results of impairment on, gain/loss on sale of and fair value change of investments, non-GAAP to GAAP reconciling items on the share of equity method investments, non-GAAP to GAAP reconciling items for the income/loss attributable to non-controlling interests, provision for income tax related to the amortization of intangible assets and fair value change of investments (other non-GAAP to GAAP reconciling items have no tax effect), and amortization of convertible debt and senior notes issuance cost. Adjusted EBITDA excludes interest income, net, income tax expenses (benefit), and depreciation expenses.

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 operating performance 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 also believes that 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. The Company’s 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. Accordingly, care should be exercised in understanding how the Company defines its non-GAAP financial measures. Reconciliations of the Company’s non-GAAP financial measures to the nearest comparable GAAP measures are set forth in the section below titled “Unaudited Reconciliation of Non-GAAP to GAAP Results.”
