支配株主等に関する事項について
Regulatory Filings Classification · 95% confidence The document is a notification about controlling shareholders and related party disclosures regarding the parent company and group relations. It describes shareholding and independence from the parent company, focusing on corporate governance and shareholder structure aspects. The text does not include financial statements, earnings data, board changes, or meeting results. It is an announcement related to regulatory disclosure about ownership and corporate group info. This fits best with Regulatory Filings (RNS) as a general regulatory announcement that does not fall into more specific categories like Annual Report, Management changes, or Earnings Release.

非上場の親会社等の決算情報に関するお知らせ
Annual Report Classification · 90% confidence The document reports the finalized financial results of a non-listed parent company, KODEN Holdings, for the fiscal year ended March 31, 2026. It includes detailed financial data such as balance sheets, income statements, and statement of changes in shareholders' equity for the full fiscal year 2025/4/1 to 2026/3/31. The content is substantive, presenting full financial statements rather than just summarizing results or announcing publication. This detailed financial disclosure corresponds to a comprehensive annual report of the parent company, even though it is presented as information from a listed subsidiary. The document is not a mere announcement or certification; it contains actual financial statements and analysis. Therefore, it should be classified as an Annual Report or similar full financial report type. Given the options, Annual Report (10-K) best fits the nature of this document as a full annual financial report of the parent company disclosed by the subsidiary. FY 2026

These substantive financial data and statements indicate this is a financial report, not merely a notice or a short announcement. There is no indication this document is an announcement of publication or a certification; instead, it contains full financial data of a fiscal year period. Given it is an annual financial statement disclosure for the parent company, the most fitting classification is an Annual Report (10-K), which covers full financial performance for a fiscal year.

Matters Regarding the Controlling Shareholder, etc.
Major Shareholding Notification Classification · 95% confidence The document is an announcement dated June 18, 2026, from Harmonic Drive Systems Inc., disclosing details about a controlling shareholder related entity (KODEN Holdings Co., Ltd.). It discusses shareholding percentages, corporate group relationships, and measures related to minority shareholders. There are no financial statements, earnings data, or meeting results included. The content focuses entirely on shareholding and controlling shareholder matters as required by regulatory rules for notifications. The document length is about 2,823 characters, which is short and reads as a formal regulatory disclosure rather than a full report or presentation. The information specifically matches the description of a Major Shareholding Notification rather than anything related to annual or interim reports, earnings, or corporate governance changes.

臨時報告書
Regulatory Filings Classification · 95% confidence The document is titled a 臨時報告書, which translates to an 'Extraordinary Report' or 'Timely Report'. It is submitted under financial regulations concerning reporting material events that could impact financial status, management results, and cash flow. The document reports a dividend received from a consolidated subsidiary and details regarding the dividend date, amount, and accounting impact. The content is about notifying a significant event affecting financials, not a full financial report or earnings release. The text is short (1228 characters), providing a specific event disclosure. Therefore, based on Japanese financial regulatory classifications, this corresponds to a Regulatory Filing (RNS), a general category for timely event disclosures that do not fit other defined financial report types.

連結子会社からの配当金受領に関するお知らせ
Regulatory Filings Classification · 95% confidence The document is a notification from a company about receiving dividends from a consolidated subsidiary. It references legal reporting requirements for submission of an 'extraordinary report' (臨時報告書) under Japanese Financial Instruments and Exchange Act. The content mainly notifies about the dividend amount received and its accounting impact, and it is labeled as an announcement ('お知らせ'). It does not contain a financial report itself but rather a regulatory disclosure about this event. This fits best under 'Regulatory Filings (RNS)' as a regulatory announcement that does not fit other categories such as Dividend Notice (DIV), since it is about received dividends from a subsidiary rather than announcing dividends to shareholders. Given the length (~510 chars) and nature, classification is RNS with high confidence.
