Filing Released Lang Actions
確認書
Regulatory Filings Classification · 82% confidence The document is a short confirmation letter (“確認書”) under Japan’s Financial Instruments and Exchange Act (Art. 24-4-2) that the company’s annual securities report for the 45th fiscal year (Jan 1 2025–Dec 31 2025) has been prepared appropriately. It is not the full securities report itself nor an earnings release or dividend notice, but a regulatory attestation accompanying the annual report. This falls under the miscellaneous regulatory filings category (RNS) rather than the actual Annual Report (10-K) or a Report Publication Announcement (RPA).

有価証券報告書-第45期(2025/01/01-2025/12/31)
Annual Report Classification · 100% confidence The document is a Japanese 'Yuka Shoken Hokokusho' (Securities Report), which is the Japanese equivalent of a 10-K annual report. It contains the header information for the fiscal year ending December 31, 2025, and is filed with the Kanto Local Finance Bureau under the Financial Instruments and Exchange Act. Given the comprehensive nature of the filing and its role as the primary annual financial disclosure for a Japanese public company, it is classified as a 10-K. FY 2025

半期報告書-第45期(2025/01/01-2025/12/31)
Interim / Quarterly Report Classification · 100% confidence The document is a '半期報告書' (Semi-Annual Report) filed by Altech Corporation (株式会社アルプス技研) with the Kanto Local Finance Bureau on August 7, 2025. It covers the interim accounting period from January 1, 2025, to June 30, 2025. It contains detailed financial statements, including the balance sheet, and is subject to an audit review by Deloitte Touche Tohmatsu. 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

確認書
Regulatory Filings Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act. It serves as an officer certification by the CEO of Altech Corporation regarding the accuracy of the interim report for the period ending June 30, 2025. Per the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations should be classified as Regulatory Filings (RNS), even if they reference a specific report type.

臨時報告書
Major Shareholding Notification Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and is filed with the Kanto Local Finance Bureau. Section 1 explicitly states the reason for filing is a change in a major shareholder ("主要株主に異動がありましたので"), citing regulations related to the Financial Instruments and Exchange Act and Cabinet Office Ordinance concerning disclosure of corporate information. Section 2 details the change in ownership percentage (crossing the 10% threshold) by FMR LLC. This type of filing, reporting a significant change in major shareholding, directly corresponds to the definition of Major Shareholding Notification (MRQ). The document length is short (1431 chars), but the content is the substantive report itself, not an announcement of a report's publication, thus overriding the RPA/RNS rule.

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" (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 reports on the company's activities regarding the repurchase of its own shares during a specific period (March 1, 2025, to March 31, 2025). This directly corresponds to the definition of 'Transaction in Own Shares' (POS), which covers share repurchase reports.
