Japan Post Insurance begins new share buyback through auction market

Japan Post Insurance Co. has commenced a treasury stock acquisition through trading on the Tokyo Stock Exchange's auction market, effective November 18, 2025. The company aims to acquire a maximum of 5,796,000 common shares, with the total acquisition amount not exceeding 22,500,003,600 yen. This buyback is structured to ensure that Japan Post Holdings Co. Ltd.'s voting rights in Japan Post Insurance remain at 50% or less.

This specific acquisition follows a broader resolution approved by the board of directors on November 14, 2025. That resolution authorized the acquisition of up to 20,000,000 common shares, representing 5.4% of issued shares (excluding treasury stock), with a total value not exceeding 45,000,000,000 yen. The period for this larger acquisition spans from November 17, 2025, to March 31, 2026, utilizing both the ToSTNeT-3 system and the auction market.

As of November 17, 2025, prior to the commencement of the auction market trading, Japan Post Insurance had already acquired 5,424,300 shares for a total amount of 22,499,996,400 yen. The actual acquisition amount for the auction market purchases may be significantly less than the stated maximum, aligning with the strategic goal of maintaining the voting rights ratio.
