Valneva Expands its Commercial Operations and Establishes US Infrastructure

Lyon (France), November 30, 2017 - Valneva SE, a fully integrated commercial stage biotech company focused on developing innovative, lifesaving vaccines, today announces further expansion of its global commercial infrastructure with Valneva USA. The fully-owned commercial subsidiary will take direct control of sales and marketing of IXIARO® in the U.S. private market with the aim of accelerating sales growth of the vaccine.

Franck Grimaud, President & CBO of Valneva, commented, "Japanese encephalitis is a potentially devastating and deadly disease for travelers visiting Asia; yet many travelers don't seek prevention with a vaccine, especially in the U.S. By giving focus through a dedicated sales & marketing team, we expect to drive further penetration and sales."

The U.S. private market represented 20% of the €53.2 million of IXIARO® revenues Valneva reported in 2016.

Valneva has successfully established its own commercial infrastructure in key travel markets over the past two years after it regained global distribution rights of its Japanese encephalitis vaccine IXIARO® in June 2015. The Company has been distributing the vaccine directly to its largest customer, the U.S. Military, and in 2015 entered into an exclusive marketing and distribution agreement for the US private market with a leading local distributor. Valneva is regaining full commercial control of IXIARO® on December 4, 2017, allowing the Company to build a stronger commercialization structure through its subsidiary Valneva USA, Inc.

About IXIARO®/JESPECT®

Valneva's Japanese Encephalitis vaccine is indicated for active immunization for the prevention of the disease for people who travel to, or live in, endemic areas. It has received marketing approval in the U.S., Europe, Canada, Hong Kong, Singapore, and Israel under the trade name IXIARO® and in Australia and New Zealand where it is marketed as JESPECT®. It is the only vaccine available to the U.S. military for Japanese Encephalitis. IXIARO® is approved for use in individuals two months of age and older in the U.S. and EU member states, Norway, Liechtenstein, Iceland, Singapore, Hong Kong, and Israel. In all other licensed territories, IXIARO®/JESPECT® is indicated for use in persons 18 years of age and above.

About Japanese Encephalitis

Japanese encephalitis is a deadly infectious disease found mainly in Asia. About 70,000 cases of JE are estimated to occur in Asia each year, although the actual number of cases is likely much higher due to underreporting in rural areas. JE is fatal in approximately 30 percent of those who show symptoms, and leaves half of survivors with permanent brain damage. The disease is endemic in Southeast Asia, India and China, a region with a population of more than three billion. In 2005, JE killed more than 1,200 children in only one month during an epidemic outbreak in Uttar Pradesh, India, and Nepal.
