Applied Nutrition Plc. shares tumbled the most since its 2024 IPO after warning of Iran War-related disruptions to its growth plans. The London-listed company, which went public last year, cited war-related operational challenges as the primary reason for the sharp decline. This marks the steepest single-day drop since the firm's market debut, signaling investor concern about near-term profitability.

The Iran conflict's impact on global supply chains and logistics appears to be the critical factor weighing on the stock. Applied Nutrition's warning underscores how geopolitical instability can rapidly erode market confidence in even established consumer goods firms. The company now faces pressure to detail mitigation strategies to reassure stakeholders about its long-term viability.
