Reports Unaudited Second Quarter 2016 Financial Results

August 23, 2016 /PRNewswire/ -- Sinovac Biotech Ltd. (NASDAQ: SVA), a leading provider of biopharmaceutical products

in China, announced today its unaudited second quarter ended June 30, 2016.

Weidong Yin, Chairman, President and CEO of the Sinovac, commented, "As forecasted on our first quarter earnings call, we

experienced a continued decline to our financial results in the second quarter due to the incident involving the improper distribution

and sale of vaccines in Shandong province. This impacted nationwide sales of private-pay market vaccines as vaccine companies halted

vaccine delivery to wait for the interpretation of new regulation by the Chinese government."

mid-June, the China Food and Drug Administration ("CFDA") and China's Ministry of Health jointly issued an interpretation

of the new requirement and execution plan during the transition period before the infrastructure is set up to fully comply with

the new regulation. This allowed vaccine sales and delivery in the private-pay market to resume following the joint government

announcement. Since then, we have experienced a rebound in sales activity. When the private-pay vaccine market was reactivated,

our sales and marketing team launched marketing activities for promoting our newly approved EV71 vaccines. There have been vaccination

kick-off ceremonies, commercial launch activities at the provincial level, as well as educational seminars and marketing activities,

as planned. By now, we have delivered our EV71 vaccine to 16 provinces and three municipalities and we expect these numbers to

Yin also commended, "During the second quarter, we also made progress on our pipeline programs with the continuation of clinical

trials of our varicella vaccine and completed preparation for the trials of our sIPV vaccine. We expect that sales in our fiscal

second half of the year will be much stronger than the first half and look forward to updating our investors on our latest progress

and achievements in the months ahead."
