Notice Concerning Share Exchange between Consolidated Subsidiaries

Tokuyama Corporation (hereinafter referred to as "Tokuyama," "the Company," or "we") hereby announces that the Company's Board of Directors resolved at a meeting held today to approve the execution of a share exchange agreement ("the Share Exchange"), which will form a wholly owned subsidiary, between its consolidated subsidiaries Formosa Tokuyama Advanced Chemicals Co., Ltd. (FTAC) and Taiwan Tokuyama Corporation (TTC). Following the signing of this agreement, TTC will, subject to the approval of the relevant authorities, become a wholly owned subsidiary of FTAC.

Having entered into an agreement with Formosa Plastics Corporation (FPC) for the purpose of manufacturing and selling high-purity isopropyl alcohol (IPA) for the electronics industry, the Company and FPC established FTAC as a joint venture company in Taiwan in October 2020 and launched a high-purity IPA business. Established in August 1996 with 100% investment from the Company as a filling and shipping base for high- purity IPA manufactured in Japan, TTC has continued to function as an important base for this business even after having becoming a joint venture between the Company and FPC in April 2024. By executing the Share Exchange and making TTC a subsidiary of FTAC, we will realize further development and expansion of our business in Taiwan.

Recognizing that TTC will remain a consolidated subsidiary of the Company after the Share Exchange, no associated profit or loss is expected to arise.
