Baidu Completes Conversion to Dual-Primary Listing in Hong Kong, Joining Industry Trend
Baidu, Inc. announced that its voluntary conversion from secondary listing to dual-primary listing on the Main Board of the Hong Kong Stock Exchange will take effect on September 1, 2026. The leading AI company with strong Internet foundation will maintain its existing presence on the Nasdaq Global Select Market while upgrading its Hong Kong status.
The conversion does not involve any issuance of new shares or fundraising activities. Following the effective date, the stock marker "S" currently identifying Baidu as a secondary-listed security will be removed from the company's stock short names for both HKD and RMB counters on the Hong Kong Stock Exchange. This marker is used by the exchange to flag securities with secondary listing status.
Regulatory Compliance and Governance Changes
As a dual-primary listed company, Baidu will be required to comply with all relevant Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited applicable to such issuers. Unlike secondary listings, which receive automatic waivers and follow primarily the rules of their home market, dual primary listings require companies to adhere to the full listing requirements of both exchanges.
The company has already taken necessary measures to meet these enhanced requirements, including restructuring the composition of its Audit Committee and Nominating and Corporate Governance Committee. Shareholders approved the conversion at an extraordinary general meeting held on August 26, 2026.
Strategic Benefits and Market Access
The conversion positions Baidu to become eligible for inclusion in Stock Connect programs that link the Hong Kong Stock Exchange with the Shanghai and Shenzhen exchanges. This mechanism would enable mainland Chinese investors to trade Baidu shares directly, potentially expanding the company's investor base significantly.
Baidu originally completed its secondary listing in Hong Kong on March 23, 2021, raising approximately HK$23.9 billion (US$3.1 billion) in gross proceeds. The shares opened at HK$254 and closed unchanged at HK$252 on the first day of trading. The company has maintained its primary Nasdaq listing since its initial public offering on August 5, 2005, when it debuted at $27 per American depositary share. In December 2007, Baidu became the first Chinese company included in the NASDAQ-100 index.
Industry-Wide Shift
Baidu's move follows a broader trend among major US-listed Chinese technology firms strengthening their Hong Kong market presence. Alibaba Group Holding Limited completed a similar conversion to dual primary listing on the Hong Kong Stock Exchange and the New York Stock Exchange on August 28, 2024.
The Hong Kong Stock Exchange introduced new rules in late 2021 establishing three pathways for secondary-listed companies to convert to primary listing status: voluntary conversion, overseas delisting, and trading migration when 55% or more of trading volume shifts to Hong Kong. Baidu pursued the voluntary conversion route.
This strategic shift occurs against a backdrop of ongoing geopolitical tensions and regulatory scrutiny. The 2020 U.S. Holding Foreign Companies Accountable Act mandates delisting of Chinese companies if U.S. authorities are denied audit access, prompting many firms to fortify their Hong Kong listings as a potential hedge against regulatory risks.
Under Hong Kong rules, companies designated as "Grandfathered Greater China Issuers" with weighted voting rights structures or variable interest entity structures can retain these governance arrangements when converting to dual primary listing, subject to certain waivers granted by the exchange.
Founded in 2000 with a mission to make the complicated world simpler through technology, Baidu trades on Nasdaq under the ticker "BIDU" and on the Hong Kong Stock Exchange under "9888" for the HKD counter and "89888" for the RMB counter. One Baidu American depositary share represents eight Class A ordinary shares.
