It includes the independent auditor's report, consolidated financial statements (Statement of Financial Position, Statement of Comprehensive Income, Statement of Changes in Equity, Statement of Cash Flows), and detailed notes.

This type of filing is a standard regulatory announcement in the Korean market (DART system) used to update financial performance metrics before the final audit report is published.
