Sinovac Temporarily Blocks Access to Its Websites

BEIJING, April 30, 2018 /PRNewswire/ -- Sinovac Biotech Ltd. (NASDAQ: SVA) ("Sinovac" or the "Company"), a leading provider of biopharmaceutical products in China, today announced that Aihua Pan, the Chairman of the Board of the Company's controlled Chinese subsidiary, Sinovac Biotech Co., Ltd. ("Sinovac Beijing"), who was appointed by Sinobioway Biomedicine Co., Ltd. ("Sinobioway"), the minority shareholder of Sinovac Beijing, inappropriately and without authorization seized control of the Company's websites, www.sinovac.com and www.sinovac.com.cn.  Out of an abundance of caution, the Company has temporarily blocked the access to the websites to avoid any further unauthorized access or tampering that could mislead any interested stakeholders.

The misappropriation of the Company's websites is another blatant attempt by Mr. Pan and Sinobioway to interfere with Sinovac's business.

The Company advises all regulators, shareholders, customers, employees, and other interested stakeholders that authorized English messages from the Company will be distributed via the Company's PR Newswire account and filings with the U.S. Securities and Exchange Commission and authorized Chinese messages from the Company will be distributed via the Company's official WeChat public account (account name: SinovacBiotech) until the Company regains control of its websites.
