Weibo Provides Update on Status under Holding Foreign Companies Accountable Act

BEIJING,March 24,2022 --Weibo Corporation ("Weibo" or the "Company") (Nasdaq: WB and HKEX: 9898),a leading social media platform in China,today provides an update on its status under the Holding Foreign Companies Accountable Act (the "HFCAA").

On March 23,2022,in connection with its implementation of the HFCAA,the U.S. Securities and Exchange Commission (the "SEC") provisionally named the Company as a Commission-Identified Issuer,following the Company's filing of its annual report on Form 20-F for the fiscal year ended December 31,2021 (the "2021 Form 20-F") with the SEC on March 10,2022. The SEC estimated that 273 registrants might be identified under the Act as part of its review of registrants in calendar year 2020.

The identification is pursuant to the HFCAA,which states if the SEC determines that a company has filed audit reports issued by a registered public accounting firm that has not been subject to inspection for the Public Company Accounting Oversight Board,or the PCAOB,for three consecutive years beginning in 2021,the SEC shall prohibit its shares or American depositary shares (the "ADSs") from being traded on a national securities exchange or in the over-the-counter trading market in the United States. The Company has previously disclosed that its independent auditor,the independent registered public accounting firm that issued the audit report included in its 2021 Form 20-F,is not currently subject to inspection by the PCAOB,hence the identification by the PCAOB is expected.

The Company's ADSs,each representing one Class A ordinary share,have been quoted on the Nasdaq Global Select Market system under the symbol "WB" since April 17,2014. The Company's Class A ordinary shares have been listed on the Main Board of the Hong Kong Stock Exchange (the "HKEX") since December 8,2021 under the stock code "9898." The Company's Class A ordinary shares listed on the HKEX and the Company's ADSs quoted on the Nasdaq are mutually fungible.

The Company will continue to monitor market developments and evaluate all strategic options.
