Major Shareholding Notification Classification · 100% confidence The document is a 'Report on Trading Plan for Specific Securities by Executives and Major Shareholders' (임원ㆍ주요주주 특정증권등 거래계획보고서) filed with the Financial Supervisory Service (증권선물위원회) and the Korea Exchange.

While it involves share transactions, it is a regulatory filing regarding a future trading plan rather than a simple 'Director's Dealing' (which usually reports past trades) or a 'Transaction in Own Shares' (which refers to company buybacks). Given the specific regulatory nature of this filing in the Korean market, it falls under the 'Regulatory Filings' category.
