訂正臨時報告書
Regulatory Filings Classification · 85% confidence The document is a Japanese ‘臨時報告書’ (timely disclosure) filed under the Financial Instruments and Exchange Act, providing details of an overseas secondary offering by a selling shareholder. It is neither an earnings release, management change, major shareholding threshold announcement, nor a direct capital‐raising by the company (no new shares issued). It does not fit other specific categories (10-K, IR, ER, MRQ, SHA, POS, CAP). Therefore it defaults to a general regulatory filing (RNS).

臨時報告書
Capital/Financing Update Classification · 65% confidence The document is a Japanese ‘臨時報告書’ disclosing the execution of a capital and business alliance agreement with Onto Innovation, including share transfer details and associated covenants. This is not an annual or quarterly report, not an earnings release, audit report, or director share dealing. It is a strategic capital tie-up announcement rather than a takeover bid or new share issuance. Under our taxonomy, it best fits as a Capital/Financing Update (CAP) because it updates the market on a material financing/strategic capital arrangement.
