[1] On a constant currency (non-GAAP) basis, we assume that the exchange rate in the second quarter of 2020 had been the same as it was in the second quarter of 2019, or RMB 6.81=US$1.00.

Second Quarter 2020 Financial Results

For the second quarter of 2020, Weibo’s total net revenues were $387.4 million, a decrease of 10% compared to $431.8 million for the same period last year.

Advertising and marketing revenues for the second quarter of 2020 were $340.6 million, a decrease of 8% compared to $370.7 million for the same period last year. Advertising and marketing revenues from key accounts (“KAs”) and small & medium-sized enterprises (“SMEs”) were $304.8 million, a decrease of 12% compared to $346.5 million for the same period last year. The decrease was primarily resulted from the adverse impact of the coronavirus pandemic on advertisers from certain industries, decrease in barter transaction revenues, as well as negative currency translation impact.

VAS revenues for the second quarter of 2020 were $46.8 million, a decrease of 23% year-over-year compared to $61.2 million for the same period last year, primarily due to the decrease of live streaming business, and was partially offset by the increase in membership revenues.

Costs and expenses for the second quarter of 2020 totaled $281.2 million, compared to $280.6 million for the same period last year. The slight change of costs and expenses was a result of modest pickup in marketing expenses, higher bad debt provision, and the decrease of cost of revenues primarily due to the exemption and refund of cultural business construction fee during this year. Non-GAAP costs and expenses were $265.5 million, compared to $265.6 million for the same period last year.

Income from operations for the second quarter of 2020 was $106.2 million, compared to $151.3 million for the same period last year. Non-GAAP income from operations was $121.9 million, compared to $166.2 million for the same period last year.

Non-operating income for the second quarter of 2020 was $132.5 million, compared to a loss of $24.0 million for the same period last year. Non-operating income for the second quarter of 2020 mainly included (i) a $121.0 million net gain from fair value change of investments, which is excluded under non-GAAP measures; and (ii) a $15.1 million net interest and other income.

Income tax expenses were $40.7 million, compared to $26.1 million for the same period last year. The increase was mainly attributable to a deferred tax charges recognized from a fair value change of investment in the second quarter this year.

Net income attributable to Weibo for the second quarter of 2020 was $198.4 million, compared to $103.0 million for the same period last year. Diluted net income per share attributable to Weibo for the second quarter of 2020 was $0.86, compared to $0.46 for the same period last year. Non-GAAP net income attributable to Weibo for the second quarter of 2020 was $114.5 million, compared to $156.4 million for the same period last year. Non-GAAP diluted net income per share attributable to Weibo for the second quarter of 2020 was $0.50, compared to $0.68 for the same period last year.

As of June 30, 2020, Weibo’s cash, cash equivalents and short-term investments totaled $2.33 billion. For the second quarter of 2020, cash provided by operating activities was $121.7 million, capital expenditures totaled $8.4 million, and depreciation and amortization expenses amounted to $6.9 million.

Other Development

On July 8, 2020, the Company completed the offering of US$750 million in aggregate principal amount of senior notes due 2030 (the “Notes”). The Notes bear annual interest at a rate of 3.375% per year, payable semiannually in arrears on January 8 and July 8 of each year, beginning on January 8, 2021. The Notes will mature on July 8, 2030, unless previously repurchased or redeemed in accordance with their terms prior to maturity.

Business Outlook

For the third quarter of 2020, Weibo estimates its net revenues to decrease by 5% to 7% year-over-year on a constant currency basis. This forecast reflects Weibo’s current and preliminary view, which is subject to change.

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 represents non-GAAP net income attributable to Weibo, excluding interest income, net, income tax expenses, 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.”
