Sinovac Biotech Announces Certain Updates Relating to Delayed Filing of Annual Report on Form 20-F

BEIJING, Aug. 14, 2017 /PRNewswire/ -- Sinovac Biotech Ltd. (NASDAQ: SVA)("Sinovac" or the "Company"), a leading provider of biopharmaceutical products in China, announced today that The NASDAQ Stock Market ("NASDAQ") has accepted the Company's plan to regain compliance with NASDAQ Listing Rule 5250(c)(1) (the "Rule") and granted an exception to the Company to extend the deadline for complying with the Rule to October 30, 2017.The Company may regain compliance at any time before October 30, 2017 upon filing with the SEC its Annual Report on form 20-F for the year ended December 31, 2016 (the "2016 Annual Report").In the event that the Company does not satisfy the terms set forth in the extension, NASDAQ will provide written notification that the Company's common shares will be subject to delisting proceedings. At that time, the Company may appeal NASDAQ's determination for a panel review.

As announced previously, on May 1, 2017, the Company filed a Form 12b-25, Notification of Late Filing, with the Securities and Exchange Commission (the "SEC") regarding the delayed filing of the 2016 Annual Report. On July 10, 2017, the Company submitted a compliance plan to NASDAQ to support its request for an extension of time to regain compliance with NASDAQ's continued listing requirements. The submission of the compliance plan is in response to a written letter from the Listing Qualifications Department of NASDAQ dated May 10, 2017 indicating that the Company was not in compliance with the Rule because the Company had failed to file the 2016 Annual Report within four months after the end of year 2016 and did not expect that it will be able to file the 2016 Annual Report within the 15-day extension period.

The 2016 Annual Report was delayed because Company's Audit Committee (the "Audit Committee") required additional time for its internal investigation regarding allegations raised in a research report by Geoinvesting. The investigation has slowed completion of the Company's financial statements and audit for the year ended December 31, 2016.The Company's management and the Audit Committee are continuing to work diligently to complete the 2016 Annual Report and file it with the SEC as soon as possible.

After the Company publicly announced the internal investigation arising from the Geoinvesting report, the SEC staff notified the Company of an enforcement inquiry related to the matters discussed in the article. The SEC staff subsequently issued a subpoena requesting documents related to the internal investigation. The Company, at the direction of the Audit Committee and with the assistance of independent counsel, has been cooperating with the SEC in response to the staff's requests for information.

In June 2017, the Company became aware of certain judgments based on bribery charges issued by Chinese courts in four provinces against various officials of the Chinese Center for Disease Control (the "CDC").  While these judgments appear to reflect an industry-wide investigation focused on CDC officials, they also referenced eight of the Company's former and current salespersons, together with sales personnel from several other Chinese vaccine companies and distributors.  However, these judgments did not name the Company or any of its directors, officers and employees as defendants. Upon becoming aware of these judgments, the Audit Committee expanded its internal investigation to review matters related to these judgments and the Company's sales practices and policies.

On July 3, 2017, a securities class action complaint was filed in the U.S. District Court for the District of New Jersey against the Company and three of its current and former officers: Mr. Weidong Yin, the Company's current chief executive officer, Ms. Nan Wang, the Company's current chief financial officer, and Mr. Danny Chung, the Company's former chief financial officer. The complaint asserts that statements in the Company's annual filings for fiscal years 2012 through 2015 were false and misleading because they failed to disclose matters relating to the alleged bribery incidents, among other allegations.  The Company is vigorously defending this lawsuit.

On July12, 2017, another securities class action complaint was filed in the Supreme Court of the State of New York against the Company and certain directors, among others. The complaint alleges that the Company's directors breached their fiduciary duties by, among other things, initiating a self-dealing going-private transaction at a per share consideration that is less than the true value of their investment in the Company. The complaint also alleges that the Company aided and abetted those alleged breaches of fiduciary duties by the Company's directors. The complaint seeks, among other things, an injunction preventing completion of the going-private transaction, damages (including rescissory damages) in favor of the plaintiff and the class, and the fees and costs associated with the litigation. The Company is vigorously defending this lawsuit as well.
