Recommendation

The sale by Japan Post Holdings Co., Ltd. is a pre-scheduled transaction under a Rule 10b5-1 plan, indicating it is not based on new material non-public information. While it reduces the beneficial ownership of a significant shareholder, it does not inherently signal a negative outlook for Aflac Inc. and therefore does not warrant a change from a 'hold' recommendation based solely on this filing.
