Cyber Incident

As previously disclosed, the Company identified an incident involving unauthorized access to a limited number of its systems in the U.S. on June 12, 2025. The Company promptly initiated its cybersecurity incident response protocols and believes it contained the unauthorized access within hours. The Company's systems were not affected by ransomware, and the Company remained able to serve its policyholders and underwrite policies, review claims, and otherwise service customers as usual.

The Company is aware of the exfiltration of certain data including claims information, health information, social security numbers and/or other personal information relating to a substantial number of customers, beneficiaries, employees, agents, and other individuals in the Company’s U.S. business. In December 2025, the Company completed a detailed review of the potentially impacted files and determined that personal information associated with approximately 22.65 million individuals was involved, and began notifying impacted individuals and regulatory authorities as required by applicable laws.

Based on the information currently available, as of the date of this report, the Company does not believe that the incident is reasonably likely to have a material impact on the Company’s financial condition or results of operations. The Company continues to assess the financial impact of the cybersecurity incident, including how much of the financial impact will be covered by insurance. As a result of the cybersecurity incident, the Company has incurred certain costs and may, depending on future developments, incur additional costs, including but not limited to: costs to provide credit monitoring, identity theft protection, and Medical Shield to impacted individuals and maintain a call center related to the provision of such services; incident response costs; expenses arising from potential litigation, governmental investigations, or enforcement actions; expenses related to compliance, finance, and legal advisory services; elevated cybersecurity insurance premiums; and costs incurred in meeting evolving legal and regulatory requirements concerning cybersecurity governance, monitoring, and disclosure. The costs associated with the incident to date, including the cost to investigate and respond to the incident as well as related legal and other professional services, resulted in a slight increase to the Company's expenses and are recorded in the insurance and other expenses line in the consolidated statement of earnings.
