SAIF Partners: Now is Your Last Chance to Vote for Board Change at Sinovac

NEW YORK--(Business Wire / Korea Newswire)--SAIF Partners IV L.P., (“SAIF Partners”, “we” or “us”), the largest single investor in Sinovac Biotech Ltd. (“Sinovac” or the “Company”) which beneficially owns approximately 15% of the Company’s outstanding common shares, today urged shareholders to immediately vote “FOR” the election of SAIF Partners’ ten highly qualified director candidates to the Company’s Board of Directors (the “Board”) using the GOLD proxy card. Sinovac’s Special Meeting of Shareholders (the “Special Meeting”) - scheduled for Tuesday, July 8 at 8:00 p.m. Atlantic Standard Time (Wednesday, July 9 at 8:00 a.m. China Standard Time) - is just days away, and time is running out to cast your vote for change.

SAIF Partners firmly believes that Sinovac’s current Board - the majority of whose members were not duly elected by shareholders or sanctioned by the Privy Council - does not act in the interests of all shareholders, and in fact only began to do so when it was publicly pressured. Further, we believe the current Board lacks integrity, industry experience, management expertise, and respect for the law necessary to fulfill its lofty promises to shareholders. As such, we do not believe the current Board has the capability to resolve the Company’s most pressing issues, including concluding its numerous lawsuits and ending the six-year suspension of the trading of Sinovac’s common shares in the public markets.

Most importantly, however, we are highly skeptical of the current Board’s ability to follow through on its plan to issue significant dividends to shareholders for several concerning reasons. These include the current Board’s failure to actively engage with management, its lack of sound financial reasoning for its proposed dividend figures, its apparent unwillingness to hire a new independent auditor after it drove Sinovac’s prior public accounting firm to resign in April, and its poor governance practices. These issues, among others, lead us to believe that the current Board has put forth its massive dividend distribution plan simply to win shareholders’ support and retain their positions, even though it lacks the capabilities to follow through on its stated promise.

Ultimately, we believe that meaningful change is urgently needed on Sinovac’s Board to restore the Company’s credibility with investors and regulators and unlock the tremendous long-term value embedded within Sinovac for all shareholders. If elected, our nominees will work closely with management to deliver shareholders the long-overdue dividends they deserve and establish a long-term business strategy that will maximize the value of the Company for all shareholders.
