BEIJING, June 26, 2018 -- Sinovac Biotech Ltd. (NASDAQ: SVA) ("Sinovac" or the "Company"), a leading provider of biopharmaceutical products in China, today announced that it has filed a motion for partial summary judgment in Delaware Chancery Court.

The motion introduces recently obtained information showing that the Sinobioway Consortium, led by Sinobioway Biomedicine Co., Ltd. ("Sinobioway"), a minority shareholder of the Company’s controlledChinese subsidiary, Sinovac Biotech Co., Ltd. ("Sinovac Beijing"), and a group of Sinovac’s shareholders led by 1Globe and OrbiMed (the “Dissident Shareholders”) reached an agreement, arrangement or understandingbefore the Company’s annual general meeting held on February 6, 2018 (the “AGM”).  Prior to the AGM, the Sinobioway Consortium and the Dissident Shareholders agreed to appear at the AGM to nominate and to vote for new directors controlled by Sinobioway or the Dissident Shareholders.

As announced previously, in March 2016 Sinovac’s board of directors adopted a shareholder rights agreement (the “Rights Agreement”) to guard against abusive or coercive tactics to gain control of the Company.  According to the Rights Agreement, ifa trigger event occurs, all shareholders of Sinovac except the Dissident Shareholders will be entitled to exercise their right to acquire additional shares and the shareholding of the Dissident Shareholders will be diluted significantly.

The summary judgment motion asks the Delaware Court to ascertain whether there is sufficient information showing that the trigger event under the Rights Agreement has occurred due to the agreement reached by the Sinobioway Consortium and the Dissident Shareholders. To protect the rights of all shareholders, the Company has filed the motion for partial summary judgment asking the Delaware Court to enter judgment, without a full trial, that the trigger event under the Rights Agreement has occurred. 

The board of directors and management of Sinovac continue to execute their fiduciary duties to act in the best interests of the Company and all shareholders as the Company moves forward in its mission to develop vaccines that enhance health in China and around the world and create shareholder value. Furthermore, the board of directors and management of Sinovac are vigorously defending the rights of all shareholders in all applicable courts.
