Japan Post Holdings Co., Ltd. sold $2.15 million worth of Aflac Inc. common stock in two transactions on April 1, 2026, while retaining an indirect holding of 51,954,900 shares. The insurer's latest trading price and valuation signals, plus a mixed fourth-quarter 2025 earnings report and an unchanged Underperform from Mizuho, frame a nuanced view of the stock.

Key Points

  • Japan Post Holdings sold $2.15 million of Aflac common stock on April 1, 2026, across two transactions and continues to indirectly own 51,954,900 shares.
  • Aflac traded at $110.48 when the transactions were reported, and InvestingPro indicated the stock appears overvalued relative to its Fair Value; the company has raised its dividend for 42 consecutive years with a current yield of 2.21%.
  • Aflac’s Q4 2025 results were mixed: EPS of $1.57 missed the $1.70 forecast (-7.65% surprise), while revenue of $4.87 billion beat the $4.28 billion forecast (+13.79% surprise); Mizuho raised its price target to $107.00 but kept an Underperform rating, estimating a -6% return.

Japan Post Holdings Co., Ltd., which holds a roughly ten percent stake in Aflac Inc. (NYSE: AFL), reported selling a total of $2.15 million in Aflac common stock on April 1, 2026. The disposition took place across two separate transactions and leaves Japan Post with an indirect ownership of 51,954,900 shares.

The first transaction comprised 13,993 shares sold at a weighted average price of $109.72, with execution prices spanning from $109.02 to $110.02. The second sale involved 5,607 shares at a weighted average price of $110.17, with trades occurring between $110.03 and $110.39.

At the time of reporting, Aflac was trading at $110.48. InvestingPro analysis cited in the filing indicates that the stock appears overvalued relative to its Fair Value. The company’s shareholder return profile includes a long track record of dividend increases, with InvestingPro Tips noting Aflac has raised its dividend for 42 consecutive years and currently yields 2.21%.

Beyond the share sales and valuation commentary, recent company results provide additional context. Aflac’s fourth-quarter 2025 earnings per share came in at $1.57, below the consensus forecast of $1.70, a negative surprise of 7.65 percent. Conversely, revenue outperformed expectations, with reported top-line results of $4.87 billion versus a $4.28 billion forecast, representing a positive surprise of 13.79 percent.

On the analyst front, Mizuho revised its price target from $104.00 to $107.00 based on a valuation roll-forward but retained an Underperform rating, projecting a negative 6 percent return for the stock even with the higher target.


Context and implications

  • The sales represent modest liquidity events by a large institutional holder and do not change Japan Post’s position as a significant shareholder given the remaining 51,954,900 shares held indirectly.
  • Market indicators cited alongside the transactions suggest a divergence between near-term trading levels and modeled Fair Value.
  • Recent earnings results and the analyst action highlight mixed operational and valuation signals for Aflac.

Risks

  • Operational and earnings uncertainty - The Q4 2025 EPS shortfall versus consensus introduces execution risk for the company’s near-term profitability outlook.
  • Analyst sentiment risk - Mizuho’s maintained Underperform rating and forecasted negative return underscore downside pressure from the investment community.
