SHANGHAI and SAN FRANCISCO and CAMBRIDGE, Mass., June 27, 2022 (GLOBE NEWSWIRE) — Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688), a patient-focused, innovative, commercial-stage, global biopharmaceutical company, today announced that it has completed its voluntary conversion of its secondary listing status to a primary listing on the Main Board of The Stock Exchange of Hong Kong Limited (the “Hong Kong Stock Exchange”). Zai Lab is now a dual-primary listed company on both Nasdaq and the Hong Kong Stock Exchange.

“As we execute our globalization and growth strategy, we are pursuing new ways to attract potential investors who share Zai Lab’s vision for discovering, developing, and commercializing medicines to improve the lives of patients worldwide,” said Billy Cho, Chief Financial Officer of Zai Lab. “We believe our conversion from secondary to primary listing status will allow us to attract more potential investors on the Hong Kong Stock Exchange, helping us to broaden our shareholder base and enhance the liquidity and profile of our securities in the global market. In addition, our ordinary shares listed on the Hong Kong Stock Exchange may soon be eligible for the China-Hong Kong Stock Connect, a link between mainland China and Hong Kong, giving Chinese investors increased ability to buy and sell our securities in Hong Kong.”
