Filing Released Lang Actions
当社子会社における固定資産（系統用蓄電所）の取得に関するお知らせ
Regulatory Filings Classification · 72% confidence The document is a Japanese press release (‘お知らせ’) disclosing that the company’s subsidiary will acquire a fixed asset (grid-connected battery storage). It describes the board resolution, rationale, asset specifications, purchase schedule, and funding. It is not an annual or interim report, not an earnings release or call transcript, nor a merger/takeover, nor a financing or share issuance event. This is a general corporate regulatory announcement of an asset acquisition, which does not fit any of the more specific categories, so it falls into Regulatory Filings (RNS).

第三者割当により発行された第17回新株予約権（行使価額修正選択権付）の行使完了及び月間行使状況に関するお知らせ
Share Issue/Capital Change Classification · 98% confidence The document is a Japanese announcement titled “第三者割当により発行された第17回新株予約権…の行使完了及び月間行使状況に関するお知らせ” describing the exercise of share subscription rights (warrants) and the resulting issuance of new shares and capital inflow. This is not a full financial report or earnings release but a specific capital change notification concerning share issuance. Therefore it best fits the Share Issue/Capital Change category (SHA).

確認書
Audit Report / Information Classification · 95% confidence The document is a 'Confirmation Letter' (Kakunin-sho) filed under the Financial Instruments and Exchange Act in Japan. This document is a mandatory attachment to the Annual Securities Report (Yukashoken Hokokusho) where the CEO confirms the accuracy of the report's contents. Since it is a regulatory filing required by law to accompany the annual report but is not the annual report itself, and does not fit into other specific categories like 'Annual Report' or 'Earnings Release', it falls under the 'Regulatory Filings' (RNS) category.
