Management Reports Classification · 90% confidence The document is titled “114年度營業報告書” and consists of narrative business performance, market analysis, production/sales figures, revenue/cost breakdown, ESG strategy, and future operational plans. It lacks full financial statement schedules and instead provides management’s commentary on results, strategy, and outlook. This aligns with a Management Discussion & Analysis (MDA) report rather than a complete Annual Report (10-K) or mere announcement. Therefore, it should be classified as a Management Report (MDA).
