Asahi flags material internal control weakness after Japan ransomware attack disrupts financial reporting

• Asahi Group Holdings flagged a material weakness in internal controls for FY2025 after a Sept. 29, 2025 ransomware attack disrupted Japan-region systems.
• Disruption blocked timely retrieval and verification of accounting data, forcing an extension to the statutory filing deadline for its Annual Securities Report.
• Unauthorized administrative access was traced to gaps in implementing information security rules, including insufficient access-rights management in parts of the infrastructure.
• Remediation has begun, including tighter administrative privilege controls and monitoring by an Information Security Committee; full remediation was not completed by year-end.
• Consolidated financial statements reflect all required corrections; the auditor issued an unqualified opinion.
