Fourth****Quarter 2024 Financial Results

For the fourth quarter of 2024, Weibo’s total net revenues were US$456.8 million, a decrease of 1% compared to US$463.7 million for the same period last year.

Advertising and marketing revenues for the fourth quarter of 2024 were US$385.9 million, a decrease of 4% compared to US$403.7 million for the same period last year. The decrease was mainly due to the underperformance of online game sector, as we faced a tough year-over-year comparison due to the concentrated release of blockbuster games in the fourth quarter of 2023. Advertising and marketing revenues excluding advertising revenues from Alibaba were US$345.5 million, a decrease of 4% compared to US$358.8 million for the same period last year.

VAS revenues for the fourth quarter of 2024 were US$71.0 million, an increase of 18% year-over-year compared to US$59.9 million for the same period last year, primarily driven by the growth of membership services and game-related revenues.

^[1]^We define constant currency (non-GAAP) by assuming that the average exchange rate of 2024 had been the same as it was in 2023, or RMB7.08=US$1.00.

Costs and expenses for the fourth quarter of 2024 totaled US$338.9 million, a decrease of 2% compared to US$344.7 million for the same period last year.

Income from operations for the fourth quarter of 2024 was US$117.9 million, compared to US$119.0 million for the same period last year. Operating margin was 26%, same as last year. Non-GAAP income from operations was US$136.2 million, compared to US$145.9 million for the same period last year. Non-GAAP operating margin was 30%, compared to 31% last year.

Non-operating loss for the fourth quarter of 2024 was US$85.1 million, compared to non-operating income of US$42.3 million for the same period last year. Non-operating loss for the fourth quarter of 2024 mainly included (i) investment related impairment of US$82.8 million, which was excluded under non-GAAP measures; (ii) loss from fair value change of investments of US$3.9 million, which was excluded under non-GAAP measures; and (iii) net interest and other income of US$1.6 million.

Income tax expenses for the fourth quarter of 2024 were US$20.0 million, compared to US$72.6 million for the same period last year. The decrease was primarily due to the accrual of withholding tax related to the earnings of the company’s wholly-foreign owned enterprise (“WFOE”). In 2024, the Company accrued withholding tax related to its WFOE's earnings for 2024 on a quarterly basis. In contrast, in the fourth quarter of 2023, the Company cumulatively accrued a US$43.7 million withholding tax related to its WFOE’s earnings for 2023 and certain years prior to 2023. These earnings have been and are expected to be remitted to Weibo Hong Kong Limited to fund the demand for U.S. dollars in business operations, payments of dividends and debts, and potential investments, etc.

Net income attributable to Weibo’s shareholders for the fourth quarter of 2024 was US$8.9 million, compared to US$83.2 million for the same period last year.

Adoption of Dividend Policy and Declarationof 2024 Dividend

On March 12, 2025, the Company's board of directors (the “Board”) adopted a cash dividend policy (the “Dividend Policy”), under which the Company may choose to declare and distribute a cash dividend each year in accordance with the memorandum and articles of association of the Company and applicable laws and regulations. Under the policy, the Board determines whether to make dividend distributions and the amount of such distributions in any particular year, depending on the Company's results of operations and earnings, cash flow, financial condition, capital requirements and other relevant considerations that the Board deems relevant.

Accordingly, on the same day, for the fiscal year of 2024, the Board declared a cash dividend of US$0.82 per ordinary share, or US$0.82 per ADS, payable in U.S. dollars, to holders of record of ordinary shares and ADSs as of the close of business on April 9, 2025, Beijing/Hong Kong Time and New York Time, respectively, in accordance with the Dividend Policy. The aggregate amount of cash dividends to be paid will be approximately US$200 million. For holders of Class A ordinary shares, in order to qualify for the dividend, all valid documents for the transfer of shares accompanied by the relevant share certificates must be lodged for registration with the Company's Hong Kong branch share registrar, Computershare Hong Kong Investor Services Limited, at Shops 1712-1716, 17th Floor, Hopewell Centre, 183 Queen's Road East, Wanchai, Hong Kong, no later than 4:30 p.m. on April 9, 2025 (Beijing/Hong Kong Time).

Non-GAAP Financial Measures

This release contains the following non-GAAP financial measures: non-GAAP income from operations, non-GAAP net income attributable to Weibo’s shareholders, non-GAAP diluted net income per share attributable to Weibo’s shareholders 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 resulting from business acquisitions, net results of impairment and provision on investments, gain/loss on sale of investments 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, income tax expense related to the amortization of intangible assets resulting from business acquisitions and fair value change of investments (other non-GAAP to GAAP reconciling items have no tax effect), and amortization of issuance cost of convertible senior notes, unsecured senior notes and long-term loans. Adjusted EBITDA represents non-GAAP net income attributable to Weibo’s shareholders before interest income/expense, net, income tax expenses/benefits, 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. 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.”
