The legal basis cited is Article 24-6, Paragraph 1 of the Financial Instruments and Exchange Act. The content details the acquisition status of treasury stock (own shares) during the reporting period (June 1 to June 30, 2025), including the total number of shares held and the progress against the authorized limit.

臨時報告書
AGM Information Classification · 100% confidence The document is titled '臨時報告書' (Extraordinary Report) and is submitted to the Kanto Local Finance Bureau. The content explicitly details the resolutions passed at the '第111回定時株主総会' (111th Annual General Meeting) held on June 25, 2025, including dividend approval, and the election/re-election of directors and audit committee members, along with the voting results (votes for, against, abstentions). This structure—reporting the results of a shareholder meeting—aligns perfectly with the definition of an AGM-Related filing, specifically reporting the outcomes of the meeting. The code 'AGM-R' (AGM Information) is the most appropriate fit for reporting the results and resolutions of an Annual General Meeting.
