Valneva Provides Update on IXIARO® Supply Contract with U.S. Department of Defense

Saint Herblain(France), August18, 2022 – Valneva SE (Nasdaq: VALN; Euronext Paris: VLA) a specialty vaccine company, today announced that the U.S. Department of Defense (DoD) has decided not to exercise the second option year of the contract¹ to supply Valneva’s Japanese encephalitis (JE) vaccine IXIARO^®.

Due to the past and ongoing impact of the COVID-19 pandemic on its operations, the DoD considers its existing IXIARO^® supply levels sufficient to meet current needs. The DoD has communicated an interest in negotiating a new supply contract in 2023, once inventory returns to standard levels. The Company expects no impact on its 2022 financial guidance as a result of this decision and will continue deliveries of IXIARO^® pursuant to the terms of the first option year, which the DoD exercised with amended terms², through the fourth quarter of 2022. The DoD has relied on IXIARO^® since 2010 to help protect personnel who are deployed to JE endemic areas, for whom JE vaccination is recommended.

The total minimum value of the existing supply contract was approximately $118 million, assuming the exercise of the second option year, which had a minimum value of approximately $36 million for 250,000 doses.

Thomas Lingelbach, President and Chief Executive Officer of Valneva, commented: “We thank the DoD for their partnership and look forward to further contract negotiations in the future. In parallel, we continue to see significant recovery in the private travel market for IXIARO^®, which more than tripled in the first half of this year compared to the first half of 2021.”

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, Canada, Norway, Liechtenstein, Iceland, Singapore, Hong Kong, Japan, the Republic of Korea and Israel. In all other licensed territories, IXIARO^®/JESPECT^® is indicated for use in persons aged 18 years or more.

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.
