Fourth Quarter 2023 Financial Results

For the fourth quarter of 2023, Weibo’s total net revenues were US$463.7 million, an increase of 3% compared to US$448.0 million for the same period last year.

Advertising and marketing revenues for the fourth quarter of 2023 were US$403.7 million, an increase of 3% compared to US$390.5 million for the same period last year. Advertising and marketing revenues excluding advertising revenues from Alibaba were US$358.8 million, an increase of 3% compared to US$348.3 million for the same period last year.

VAS revenues for the fourth quarter of 2023 were US$59.9 million, an increase of 4% year-over-year compared to US$57.5 million for the same period last year, primarily attributable to increase of game-related revenues.

Costs and expenses for the fourth quarter of 2023 totaled US$344.7 million, an increase of 20% compared to US$287.5 million for the same period last year. The increase of costs and expenses was primarily due to lower general and administrative expenses booked in the fourth quarter of 2022, because of the reversal of US$58.8 million compensation expenses previously accrued, based on a contingent payment arrangement between the Company and the founder of Shanghai Jiamian Information Technology Co., Ltd. (“JM Tech”), an entity consolidated into the Company’s financial statements since the fourth quarter of 2020.

^[1]^ On a constant currency (non-GAAP) basis, we assume that the average exchange rate of 2023 had been the same as 2022, or RMB 6.73=US$1.00.

Income from operations for the fourth quarter of 2023 was US$119.0 million, compared to US$160.5 million for the same period last year. Operating margin was 26%, compared to 36% last year. Non-GAAP income from operations was US$145.9 million, compared to US$152.0 million for the same period last year. Non-GAAP operating margin was 31%, compared to 34% last year.

Non-operating income for the fourth quarter of 2023 was US$42.3 million, compared to a loss of US$21.1 million for the same period last year. Non-operating income for the fourth quarter of 2023 mainly included (i) a US$25.4 million gain from fair value change of investments, which was excluded under non-GAAP measures; and (ii) a US$16.7 million net interest and other income.

Income tax expenses for the fourth quarter of 2023 were US$72.6 million, compared to benefits of US$18.7 million for the same period last year. The increase was primarily due to (i) the reversal recorded in the fourth quarter of 2022 of previously recognized tax liabilities related to uncertain tax positions; and (ii) withholding tax paid and accrued related to the Company’s wholly-foreign owned enterprise’s ("WFOE") earnings, remitted and to be remitted to Weibo Hong Kong Limited in the foreseeable future to fund its 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 2023 was US$83.2 million, compared to US$141.9 million for the same period last year. Diluted net income per share attributable to Weibo’s shareholders for the fourth quarter of 2023 was US$0.34, compared to US$0.60 for the same period last year. Non-GAAP net income attributable to Weibo’s shareholders for the fourth quarter of 2023 was US$76.4 million, compared to US$178.5 million for the same period last year. Non-GAAP diluted net income per share attributable to Weibo’s shareholders for the fourth quarter of 2023 was US$0.31, compared to US$0.75 for the same period last year.

As of December 31, 2023, Weibo’s cash, cash equivalents and short-term investments totaled US$3.2 billion. For the fourth quarter of 2023, cash provided by operating activities was US$218.2 million, capital expenditures totaled US$7.5 million, and depreciation and amortization expenses amounted to US$14.7 million.

Fiscal Year 2023 Financial Results

For fiscal year 2023, Weibo’s total net revenues were US$1.76 billion, a decrease of 4% compared to US$1.84 billion in 2022.

Advertising and marketing revenues for 2023 were US$1.53 billion, a decrease of 4% compared to US$1.60 billion in 2022, primarily due to the unfavorable impact from the overall depreciation of RMB against the U.S. dollar on a year-over-year basis. Advertising and marketing revenues excluding advertising revenues from Alibaba were US$1.42 billion, a decrease of 5% compared to US$1.49 billion for 2022.

VAS revenues for 2023 were US$225.8 million, a decrease of 6% compared to US$239.7 million for 2022.

Costs and expenses for 2023 totaled US$1.29 billion, compared to US$1.36 billion for 2022. The decrease of costs and expenses was primarily attributable to (i) the unfavorable impact from the overall depreciation of RMB against the U.S. dollar on a year-over-year basis; and (ii) the decrease of personnel-related costs. These decreases were partially offset by the increase of general and administrative expenses in 2023, primarily resulted from the fluctuation of compensation expenses relating to JM Tech.

Income from operations for 2023 was US$472.9 million, compared to US$480.5 million for 2022. Operating margin for 2023 was 27%, compared to 26% last year. Non-GAAP income from operations was US$592.1 million, compared to US$601.1 million for 2022. Non-GAAP operating margin was 34%, compared to 33% last year.

Non-operating income for 2023 was US$29.8 million, compared to a loss of US$352.4 million for 2022. Non-operating income in 2023 mainly included (i) a US$43.0 million gain from fair value change of investments, which is excluded under non-GAAP measures; and (ii) a US$25.7 million investment related impairment, which is excluded under non-GAAP measures; and (iii) net interest and other income of US$11.3 million.

Income tax expenses for 2023 were US$145.3 million, compared to US$30.3 million for 2022. The increase in income tax expense was primarily due to (i) the reversal recorded in the fourth quarter of 2022 of previously recognized tax liabilities related to uncertain tax positions; and (ii) withholding tax paid and accrued related to the Company’s WFOE’s earnings, remitted and to be remitted to Weibo Hong Kong Limited in the foreseeable future to fund its demand for U.S. dollars in business operations, payments of dividends and debts, potential investments, etc.

Net income attributable to Weibo’s shareholders for 2023 was US$342.6 million, compared to US$85.6 million for 2022. Diluted net income per share attributable to Weibo’s shareholders for 2023 was US$1.43, compared to US$0.36 for 2022. Non-GAAP net income attributable to Weibo’s shareholders for 2023 was US$450.6 million, compared to US$540.1 million for 2022. Non-GAAP diluted net income per share attributable to Weibo’s shareholders for 2023 was US$1.88, compared to US$2.27 for 2022.

For fiscal year 2023, cash provided by operating activities was US$672.8 million, compared to US$564.1 million for 2022, an increase of 19% year-over-year. Capital expenditures totaled US$36.8 million, and depreciation and amortization expenses amounted to US$58.5 million.

Recent Developments

Completion of Convertible Senior Notes Offering

In December 2023, the Company completed an offering of convertible senior notes due 2030 in an aggregate principal amount of US$330 million (the “Notes”), which reflected the exercise in full by the initial purchaser of its option to purchase an additional US$30 million in aggregate principal amount of the Notes. The Notes bear interest at a rate of 1.375% per year, payable semi-annually in arrears on June 1 and December 1 of each year, beginning on June 1, 2024. The Notes will mature on December 1, 2030, unless redeemed, repurchased or converted earlier in accordance with their terms prior to such date. In order to facilitate the short positions by some holders of the Notes for purposes of hedging their investment in the Notes, the Company lent 6,233,785 ADSs to an affiliate of the initial purchaser of the Notes.

Special Cash Dividend

On March 14, 2024, the Company’s board of directors has approved a special cash dividend of US$0.82 per ordinary share and ADS to holders of its ordinary shares and ADSs as of the close of business on April 12, 2024, Beijing/Hong Kong Time and New York Time, respectively, payable in U.S. dollars. 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 12, 2024 (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, non-cash compensation cost to non-controlling interest shareholders, impairment of intangible assets, 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 excludes 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.”

(1)  To adjust impairment and provision on investments, gain/loss on sale of investments and fair value change of investments.

(2)  To adjust the income tax effects of non-GAAP adjustments, which primarily related to amortization and impairment of intangible assets resulting from business acquisitions and fair value change of investments. Other non-GAAP adjustment items have no tax effect, because (i) they were recorded in entities established in tax free jurisdictions, or (ii) full valuation allowances were provided for related deferred tax assets as it is more-likely-than-not they will not be realized.

(3)  To adjust the number of shares for dilution resulted from convertible senior notes which were anti-dilutive under GAAP measures.

* Net income attributable to Weibo’s shareholders is adjusted for interest expense of convertible senior notes for calculating diluted EPS.
