• The Company’s revenue-generating commercial portfolio of traveler’s vaccines, including the ongoing launches of IXCHIQ^® against chikungunya virus
• The Company’s clinical and preclinical R&D pipeline, which includes ongoing clinical development for IXCHIQ^® (Phase 4 and other studies), SV4 against Shigella in Phase 2, and VLA1601 against Zika virus in Phase 1. Valneva will also discuss further R&D pipeline development and selected current lead targets.
• There will also be a brief financial overview highlighting 2024 and mid-term guidance.

Thomas Lingelbach, Chief Executive Officer of Valneva, said, “It’s a pivotal time for Valneva as we approach the third and final tick season before the conclusion of the Phase 3 trial of our Lyme disease vaccine, VLA15, next year. If approved and commercialized by our partner Pfizer, we believe we can achieve sustained profitability from 2027, also supported by the revenue growth we expect from our existing portfolio of travel vaccines over the years to come, including the global launches and uptake of IXCHIQ^®. We are committed to continue investing in developing differentiated vaccines in areas of high unmet medical – in line with our vision to contribute to a world in which no one dies or suffers from a vaccine preventable disease.”
