Filing Released Lang Actions
訂正発行登録書
Regulatory Filings Classification · 70% confidence The document is a Japanese “訂正発行登録書” (Corrected Issuance Registration Statement) filed with the Kanto Local Finance Bureau under Japan’s Financial Instruments and Exchange Act. It is a regulatory compliance filing regarding corporate bond issuance registration, not a standard financial report (e.g., Annual Report or Interim Report) nor a press release of financial results. It does not match specialized categories like CAP (Financing Update) because it is the formal registration statement, nor IRAT (interest rate notice). Therefore it should be classified as a general regulatory filing (RNS).

臨時報告書
Transaction in Own Shares Classification · 95% confidence The document is titled “臨時報告書” and is a timely disclosure under Japan’s Financial Instruments and Exchange Act, describing the disposal of treasury shares (“自己株式処分”) to the employee shareholding plan. It details the number of shares to be disposed of, pricing, contracts, schedule, and conditions—i.e., a company’s sale/issuance of its own shares. This matches the definition for Transaction in Own Shares (POS).

従業員持株会向け譲渡制限付株式インセンティブとしての自己株式の処分に関するお知らせ
Transaction in Own Shares Classification · 90% confidence The document is a formal market disclosure by NGK Corporation detailing the Board resolution to dispose of treasury shares to its employee shareholding association under a restricted stock incentive plan. It specifies the number of shares, disposal price, total amount, method (third-party allotment), purpose, and legal conditions. This is a transaction involving the company’s own shares (treasury share disposal), fitting the definition of a “Transaction in Own Shares (POS)” rather than an earnings release, board change notice, or financial report.
2026-05-21 Japanese
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 · 99% confidence The document is a statutory repurchase status report filed under Japan’s Financial Instruments and Exchange Act (Article 24-6), detailing the company’s own share acquisition (buyback) quantities and related board resolutions. It is not a full financial report nor an announcement of a dividend or governance change, but clearly a Transaction in Own Shares report. Therefore, it matches the POS category.
