Mitsubishi Chemical Group Corporation (MCG) hereby announces, as detailed below, that it has decided to deliver restricted shares to Corporate Executive Officers of MCG at the meeting of MCG's Compensation Committee held on April 16, 2026, and to deliver restricted shares to Executive Officers of MCG at the meeting of the Corporate Executive Officers Committee held on April 23, 2026.

In addition, MCG also announces that Mitsubishi Chemical Corporation (MCC), a subsidiary of MCG, decided to deliver restricted shares to Executive Officers of MCC at the meeting of Board of Directors held on April 23, 2026.

MCG decided, at the meeting of its Compensation Committee held on February 28, 2020, to introduce a restricted shares compensation program for Corporate Executive Officers, under which the transfer restrictions will be lifted when certain officers of MCG retire from their positions. The purposes are to provide an incentive for the continuous improvement of MCG's corporate value and shareholder value over the medium to long term, to enhance retention, and to share further value with shareholders. In 2022, MCG also introduced a similar restricted shares compensation program for Executive Officers. MCG has been delivering restricted shares pursuant to the restricted shares compensation program from April 2023 onwards through the Executive Compensation BIP Trust established with Mitsubishi UFJ Trust and Banking Corporation as the trustee, and MCC will also deliver shares in a similar manner (the method of delivering shares through a trust is hereinafter referred to as the 'Delivery Scheme'). MCG decided at the meeting of its Compensation Committee held on April 16, 2026, to deliver 40,531 common shares of MCG as restricted shares through the Delivery Scheme to three (3) Corporate Executive Officers of MCG after taking into account the purpose of awarding the restricted shares, MCG's performance, the scope of duties of each Corporate Executive Officer, and various other circumstances. MCG also decided at the meeting of its Corporate Executive Officers Committee held on April 23, 2026, to deliver 13,731 common shares of MCG as restricted shares through the Delivery Scheme to three (3) Executive Officers of MCG considering the same circumstances as above. Furthermore, MCC decided at the meeting of Board of Directors held on April 23, 2026, to deliver 59,879 common shares of MCG as restricted shares through the Delivery Scheme to eleven (11) Executive Officers of MCC, taking into account the same circumstances as above.
