Filing Released Lang Actions
(Correction, Numerical Data Correction) Partial Correction to Financial Results and Related Materials for the Fiscal Year Ended March 31, 2026
Regulatory Filings Classification · 80% confidence The document is a press news release dated June 5, 2026 announcing partial corrections to the previously disclosed full‐year (fiscal year ended March 31, 2026) consolidated financial results, supplementary materials, and performance review. It provides “before and after” corrected tables and figures, but it is not the initial earnings release, nor a full Annual Report or interim financial report. It is a regulatory announcement detailing restatements. This falls under the fallback category “Regulatory Filings (RNS).”

（訂正・数値データ訂正）「2026年3月期 決算短信〔日本基準〕(連結)」、「2026年3月期 決算補足資料」及び「2026年3月期 決算説明会資料」の一部訂正について
Regulatory Filings Classification · 80% confidence The document is a correction notice (“訂正・数値データ訂正”) for previously released financial materials: the annual “決算短信” (earnings release summary), supplemental financial data, and investor presentation materials. It amends numerical data (cash flows, capex, depreciation) in those filings. This is not the original earnings release or investor presentation itself but a regulatory announcement of corrections. It does not fit a specific category like board changes, dividends, financing, or M&A, so it falls under the general “Regulatory Filings” (RNS) fallback.
2026-06-05 Japanese
連結子会社の解散及び清算に関するお知らせ
Regulatory Filings Classification · 55% confidence The document is a corporate announcement by KOA Corporation about the decision to dissolve and liquidate its consolidated subsidiary. It provides the subsidiary overview, reasons for dissolution, financial history, and schedule—typical of a regulatory disclosure notice rather than an actual financial report, earnings release, management change notice, or merger filing. It does not fit specific categories like M&A, earnings release, or management change. Therefore, it falls under the general regulatory announcement/fallback category.
