Japan Post Holdings Co., Ltd., a holder of roughly ten percent of Aflac Inc. (NYSE: AFL), sold 165,100 shares of the insurer’s common stock on April 8, 2026, according to a Form 4 filing with the Securities and Exchange Commission.
The three separate transactions were executed at prices ranging from $111.78 to $112.98 and resulted in gross proceeds of $18,655,547. The filing details each tranche: 21,691 shares at a weighted average price of $111.78; 135,376 shares at a weighted average price of $112.44; and 8,933 shares at a weighted average price of $112.98.
After completing the disposals, Japan Post Holdings still indirectly owns 51,723,100 Aflac shares, preserving a significant equity position in the insurance company, which carries a market capitalization of $57.5 billion.
Market pricing around the time of the filing showed Aflac stock trading at $111.79. According to InvestingPro data reported alongside the filing, that quote sits above the platform’s Fair Value estimate and places the stock on its list of most overvalued names.
Other company-level metrics noted in the filing and related commentary: Aflac has increased its dividend for 42 consecutive years, the shares trade at a price-to-earnings ratio of 16.62 and yield 2.16%.
The insider sale coincides with the release of Aflac’s fourth-quarter 2025 financial results. The company reported earnings per share of $1.57, which fell short of the $1.70 figure analysts had expected - a 7.65% downside surprise. Revenue for the quarter came in at $4.87 billion, ahead of consensus estimates of $4.28 billion, representing a 13.79% upside surprise.
Analyst coverage following the results shows a cautious tone: Barclays reiterated an Underweight rating with a $101 price target, while Mizuho raised its target to $107 from $104 but retained an Underperform rating, noting a valuation roll-forward and projecting a negative 6% return for the stock.
These transactions and results provide a contemporaneous snapshot of shareholder activity and near-term analyst views. Japan Post’s sale is a measurable reduction in position size but leaves it as a substantial holder of Aflac shares.
