The shareholders' meeting resolution dates for the first and second absorption-type company splits will be set separately for PPC and the new company, respectively, and the wording related to the requirements for the second absorption-type company split has been corrected.\n\n### Subsequent Procedures and Impact\nImplementation of this integration is conditional upon completion of approval procedures such as those by the Japan Fair Trade Commission, and the schedule may be changed depending on the status or reasons of those procedures. The first absorption-type company split was described as a simplified split by Mitsubishi Materials Corporation and the second as an abbreviated split at the new company, both originally noted as not requiring approval by shareholders' meetings; after correction, an approval shareholders' meeting resolution date has also been set for the new company.","jir_financial_highlights":"Approval shareholders' meeting resolution date for the absorption-type company split agreement (new company): January 2027 (scheduled) (Unknown)\nEffective date of the absorption-type company split: 2027-02-01 (scheduled) (Unknown)","jir_category":"","jir_hashtags":"#MitsubishiMaterials, #DisclosureUpdate, #BusinessIntegration","jir_key_figures":"Approval shareholders' meeting resolution date for the absorption-type company split agreement (new company): January 2027 (scheduled)\nEffective date of the absorption-type company split: 2027-02-01 (scheduled)\nPost-correction approval shareholders' meeting resolution date for the absorption-type company split agreement (new company): January 2027 (scheduled)","jir_meta_title":"Mitsubishi Materials Corporation Correction: Final Agreement Amended for Copper Concentrate Purchase and Refined Copper Sales Integration\uff5c2026\/11\/11","jir_meta_description":"Mitsubishi Materials Corporation has published a correction to the final agreement for the absorption-type company split integrating copper concentrate purchasing and refined copper sales.
