2026年12月期　第１四半期決算短信〔日本基準〕（連結）

Regulatory Filings Classification · 100% confidence The document is a 'Confirmation Letter' (確認書) filed under the Financial Instruments and Exchange Act, Article 24-4-2, Paragraph 1. It serves as an officer certification confirming the accuracy of the company's Annual Securities Report (有価証券報告書).
