Muutos Valmet Oyj:n omien osakkeiden määrässä
Transaction in Own Shares Classification · 100% confidence The document is a stock exchange release from Valmet Oyj announcing a change in the number of its own shares held by the company. It details a directed share issue used to pay out rewards for long-term incentive plans. This falls under the category of 'Transaction in Own Shares' (POS), as it specifically reports the transfer of treasury shares to participants of an incentive program, resulting in a change in the company's holdings.

Valmetin puolivuosikatsaus 1. tammikuuta - 30. kesäkuuta 2025: Vahva orgaaninen kasvu saaduissa tilauksissa ja uusi ‘Lead the Way' -strategia julkaistiin toisella neljänneksellä
Interim / Quarterly Report Classification · 100% confidence The document is a 'puolivuosikatsaus' (half-year report) for Valmet Oyj covering the period from January 1 to June 30, 2025. It contains comprehensive financial data, including income statements, segment performance, key financial ratios, and management commentary on strategy and outlook. As it provides substantive financial results for a period shorter than a full fiscal year, it is classified as an Interim/Quarterly Report. H1 2025

Valmet's Half Year Financial Review January 1 - June 30, 2025: Strong organic growth in orders received and the new ‘Lead the Way' strategy launched in the second quarter
Interim / Quarterly Report Classification · 100% confidence The document is a 'Half Year Financial Review' for Valmet, covering the period January 1 to June 30, 2025. It contains detailed financial statements, segment performance, key figures, and management commentary. It is a comprehensive interim report rather than a mere announcement or summary, fitting the definition of an Interim/Quarterly Report (IR). H1 2025

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 it 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 specific report details the acquisition and disposal status of treasury stock (own shares) over a defined reporting period (June 1 to June 30, 2025). This directly corresponds to the definition of a report detailing the company buying back or selling its own shares, which is classified as 'Transaction in Own Shares' (POS). The document is a detailed report, not an announcement of a report, so RPA/RNS is not appropriate.

有価証券届出書（参照方式）
Share Issue/Capital Change Classification · 98% confidence The document explicitly identifies itself on the cover page as a "有価証券届出書" (Securities Registration Statement). This filing type in Japan is used to register securities offerings with the Financial Services Agency (Kanto Local Finance Bureau in this case). The content details the offering of new shares (19,334 shares) through a self-share disposal method, primarily for executive and employee compensation plans (stock remuneration systems). This type of comprehensive registration document for a public offering or disposal of securities aligns most closely with the regulatory filing nature, but specifically, it is a registration statement for a capital change/share issue related to compensation. Given the provided codes, the closest fit for a formal, comprehensive regulatory filing detailing a capital structure change (share issuance/disposal) is not perfectly captured by the standard US SEC codes (like 10-K or S-1). However, since it is a formal registration document detailing the issuance of shares (募集有価証券), it is a core regulatory filing. In the context of the provided definitions, while it involves capital/financing (CAP), the document itself is the formal registration statement required by law for this specific issuance. Since it is a formal, detailed regulatory document concerning the issuance of securities, and not just a brief announcement of a report (RPA) or a general regulatory notice (RNS), it is best classified as a specific type of regulatory filing. Given the options, and recognizing that this is a Japanese regulatory filing for a share issuance, it falls under the broad category of regulatory disclosure. If a specific code for a Japanese Registration Statement (like 'S-1' equivalent) were available, that would be ideal. Lacking that, and noting the document's primary function is to register the issuance of shares (a capital event), 'CAP' (Capital/Financing Update) is plausible, but 'RNS' (Regulatory Filings - fallback) or a specific code for registration statements would be better. Since the document is a full registration statement detailing the terms of a share issuance (self-disposal for compensation), and it is not a quarterly/annual report, the most appropriate classification among the choices, given its nature as a formal, required disclosure document for a capital transaction, is often grouped with general regulatory filings if a specific registration statement code is missing. However, because the core subject is the issuance/disposal of shares for compensation, 'CAP' (Capital/Financing Update) captures the substance of the transaction being registered. Given the detailed nature and the explicit reference to '有価証券届出書' (Securities Registration Statement), it is a mandatory, comprehensive filing. I will lean towards the most specific category related to the transaction described, which is the issuance of shares for compensation, which is a financing/capital activity, but since it is a formal registration document, 'RNS' (Regulatory Filings) serves as the best catch-all for non-standardized regulatory forms, or 'CAP' for the substance. Given the structure, it is a formal registration document, which is a type of regulatory filing. I will select RNS as the most appropriate fallback for a specific Japanese registration form not explicitly listed, as it is a mandatory regulatory disclosure.

臨時報告書
Share Issue/Capital Change Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report) and is submitted to the Kanto Local Finance Bureau Director on June 27, 2025. The content explicitly states the reason for filing under Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act, which pertains to extraordinary reports. The core subject is the resolution by the Board of Directors to grant units under a 'Restricted Stock Unit Plan' (事後交付型譲渡制限付株式ユニット制度) to directors and executive officers. This type of filing, reporting a significant corporate action (like executive compensation/incentive plans) via an extraordinary report in Japan, is generally classified as a general regulatory filing or a specific corporate action report. Since the action involves executive compensation/incentives, it relates to governance and remuneration, but the document itself is a mandatory regulatory disclosure (臨時報告書) about a capital/share-based compensation scheme. Given the options, this is a mandatory regulatory disclosure concerning executive compensation/share issuance, but it is not the DEF 14A (Remuneration Information) which is typically US-centric, nor is it a standard 10-K or IR. It is a specific, non-periodic regulatory filing. In the context of the provided definitions, while it touches upon remuneration, the primary nature is a mandatory disclosure of a share-based incentive plan resolution. Since there isn't a specific code for 'Share-based Compensation Disclosure' and it's a formal regulatory filing (臨時報告書) that doesn't fit perfectly into the other specific categories (like DIV, CAP, or ER), the most appropriate general regulatory fallback is RNS, or potentially SHA (Share Issue/Capital Change) due to the nature of the units leading to share issuance. However, as it is a formal, mandatory, non-periodic disclosure required by law (Financial Instruments and Exchange Act), RNS (Regulatory Filings - general regulatory announcements and fallback) is the safest classification for a Japanese 'Rinji Hokokusho' that isn't a standard periodic report.
