Further, on August 22, 2025, the U.S. Food and Drug Administration (FDA) suspended the marketing application for IXCHIQ due to safety concerns. This news resulted in another substantial decline in Valneva's ADR price, falling $2.21 per ADR or 18.99% to close at $9.43 per ADR on August 25, 2025, as the Morningstar report also noted.
