Japan Post Insurance completes initial share buyback, plans further market purchases

Japan Post Insurance Co., Ltd. announced on November 17, 2025, the completion of its treasury stock acquisition through the Tokyo Stock Exchange's Off-auction Own Share Repurchase Trading System (ToSTNeT-3). The company acquired 5,424,300 common shares for a total of 22,499,996,400 yen. This acquisition marks the initial phase of a larger buyback program resolved by the board of directors on November 14, 2025.

The total acquisition amount via ToSTNeT-3 did not reach the maximum limit approved by the board, which targeted up to 20,000,000 shares for a maximum of 45,000,000,000 yen. Consequently, Japan Post Insurance intends to commence further treasury stock acquisition through open market trading on the auction market starting November 18, 2025, continuing until March 31, 2026.

Future open market purchases will be executed while maintaining Japan Post Holdings Co., Ltd.'s voting rights ratio in Japan Post Insurance at 50% or less. The actual acquisition amount for these subsequent purchases may be significantly less than the remaining approved amount, with further decisions to be promptly announced.
