Item 8.01 Other Events.
On June 12, 2025, Aflac Incorporated, a Georgia corporation (the “Company”), identified unauthorized access to its network. The Company promptly initiated its cybersecurity incident response protocols and believes that it contained the intrusion within hours. The Company’s business remains operational, and its systems were not affected by ransomware. The Company continues to serve its policyholders as it responds to this incident and can underwrite policies, review claims, and otherwise service customers as usual. The Company has engaged leading third-party cybersecurity experts to support the Company’s response to the incident.
The Company has commenced a review of potentially impacted files. That review is in its early stages. The Company is unable to determine the total number of affected individuals until that review is completed. The potentially impacted files contain claims information, health information, social security numbers, and/or other personal information, related to customers, beneficiaries, employees, agents, and other individuals in its U.S. business. The Company anticipates notifying regulators and providing appropriate notifications to individuals affected by this incident. Individuals will be offered free credit monitoring and identity theft protection services.
At this time, the full scope and potential ultimate impact on the Company are not known.
FORWARD-LOOKING INFORMATION
The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” to encourage companies to provide prospective information, so long as those informational statements are identified as forward-looking and are accompanied by meaningful cautionary statements identifying important factors that could cause actual results to differ materially from those included in the forward-looking statements. The company desires to take advantage of these provisions. This document contains cautionary statements identifying important factors that could cause actual results to differ materially from those projected herein, and in any other statements made by company officials in communications with the financial community and contained in documents filed with the Securities and Exchange Commission (SEC). Forward-looking statements are not based on historical information and relate to future operations, strategies, financial results or other developments. Furthermore, forward-looking information is subject to numerous assumptions, risks and uncertainties. In particular, statements containing words such as “expect,” “anticipate,” “believe,” “goal,” “objective,” “may,” “should,” “estimate,” “intends,” “projects,” “will,” “assumes,” “potential,” “target,” "outlook" or similar words as well as specific projections of future results, generally qualify as forward-looking. Factors that could cause actual results to differ materially from those expressed or implied include the Company’s discovery of additional information related to the incident, legal, reputational, and financial risks resulting from the incident, any potential regulatory inquiries, enforcement actions and/or litigation to which the Company may become subject in connection with the incident, any contract terminations, disputes or loss of business, and other additional costs that may be incurred by the Company in connection with the incident. Aflac undertakes no obligation to update such forward-looking statements.
