Sinovac Sets the Record Straight Regarding False Statements by Shandong Sinobioway Biomedicine Co., Ltd.


 BEIJING, April 18, 2018 -- Sinovac Biotech Ltd. (NASDAQ: SVA) ("Sinovac " or the "Company"), a leading provider of biopharmaceutical products in China, today issued the following statement to set the record straight following a series of false statements and damaging actions by Shandong Sinobioway Biomedicine Co., Ltd. (“Shandong Sinobioway”) intended to mislead and publicly harm the interest of Sinovac and our shareholders:

“Contrary to Shandong Sinobioway’s claims, Sinovac Biotech Co., Ltd. (“Sinovac Beijing”), one of our controlled subsidiaries in China, has never refused to provide the financial statements requested by Sinobioway Biomedicine Co., Ltd. (“Sinobioway”), a wholly owned subsidiary of Shandong Sinobioway,  regarding its 26.91% minority shareholding interest in Sinovac Beijing. Sinovac Beijing will deliver its audited 2017 annual financials to Sinobioway upon completion of its annual audit. We have been in regular communications with Sinobioway regarding the planned timing of the completion of the audit and have responded to their requests for information, before the above mentioned false statement was issued by Shandong Sinobioway. 

On April 17, 2018, Aihua Pan, the Chairman of the Board of Sinovac Beijing appointed by Sinobioway, and dozens of unnamed individuals forcibly entered Sinovac Beijing’s corporate offices and limited the physical movements of employees in Sinovac Beijing’s general manager’s office and finance department in an attempt to wrongfully take control of Sinovac Beijing’s offcial seal, legal documents, accounting seal, financial documents and financial information systems. In addition, these individuals disrupted Sinovac Beijing’s hepatitis A vaccine production and seasonal flu vaccine production by cutting power, seriously impacting Sinovac Beijing’s production and manufacturing processes and very possibly damaging product quality. Due to Sinobioway’s actions, Sinovac Beijing has been forced to destroy affected products. To maintain product safety, Sinovac Beijing has decided to stop production at the impacted facility at this time and will take every action to eliminate any biological safety risks due to the power outage. 

The false statements from Shandong Sinobioway and damaging actions by Sinobioway are further attempts to confuse the investing public, undermine our important work of delivering critical vaccines to the public, and harm our shareholders.  Our Board of Directors and management will continue to take all appropriate actions to protect the interests of all our shareholders.
