意見表明報告書
M&A Activity Classification · 100% confidence The document is an 'Opinion Statement Report' (意見表明報告書) filed by Prime Strategy Co., Ltd. in response to a tender offer (公開買付け) initiated by GMO Internet Group. It details the company's board resolution regarding the tender offer, the rationale for the board's opinion, and the background of the capital and business alliance. This is a standard regulatory filing required under the Financial Instruments and Exchange Act of Japan when a company expresses its opinion on a tender offer for its shares.

自己株券買付状況報告書（法２４条の６第１項に基づくもの）
Transaction in Own Shares Classification · 100% confidence The document is titled "自己株券買付状況報告書" (Report on the Status of Treasury Stock Acquisition) and explicitly cites the legal basis as "金融商品取引法第24条の６第１項" (Financial Instruments and Exchange Act Article 24-6, Paragraph 1). This type of filing in Japan details the company's activity regarding the purchase and disposal of its own shares during a specific reporting period (June 1 to June 30, 2025). This directly corresponds to the definition of a report on the company buying back or selling its own shares, which is classified as 'Transaction in Own Shares' (POS). Although it is a regulatory filing, POS is the more specific category than the general RNS.

確認書
Report Publication Announcement Classification · 100% confidence The document text contains the title "第２四半期報告書" (Second Quarter Report) and explicitly mentions the period covered ("第23期中（自 2024年12月１日 至 2025年５月31日"). It is a formal declaration confirming the appropriateness of the content of this semi-annual report, submitted to the Kanto Local Finance Bureau Director, referencing the Financial Instruments and Exchange Act. This structure strongly indicates a comprehensive financial report for a period shorter than a year, which aligns with the definition of an Interim / Quarterly Report (IR). Although it contains a confirmation statement, the core subject matter is the semi-annual financial reporting itself, making 'IR' a more accurate classification than 'RPA' or 'RNS', especially given the explicit mention of the financial period and report type.

This fits the definition of an Interim/Quarterly Report (IR) as it provides comprehensive financial data for a period shorter than a full fiscal year. H1 2025

自己株券買付状況報告書（法２４条の６第１項に基づくもの）
Transaction in Own Shares Classification · 100% confidence The document title is "自己株券買付状況報告書（法24条の６第１項に基づくもの）" which translates to "Report on the Status of Treasury Stock Acquisition (Based on Article 24-6, Paragraph 1 of the Financial Instruments and Exchange Act)". This document details the company's treasury stock (own share) acquisition activities over a specific reporting period (May 1, 2025, to May 31, 2025). This specific type of filing, reporting on share repurchases, directly corresponds to the definition of 'Transaction in Own Shares' (POS). Although it is a regulatory report, the specific nature of reporting share buybacks makes POS the most accurate classification over the general 'RNS' fallback.
