This study aims to analyze the comparison of the financial performance of mining companies listed on the Indonesia Stock Exchange (IDX) before and after a strategic macroeconomic event. Financial performance was measured using the Current Ratio (CR), Return on Assets (ROA), Debt-to-Equity Ratio (DER), Total Asset Turnover (TATO), and Price Earnings Ratio (PER). The research employed a comparative descriptive quantitative approach. The sample was selected using purposive sampling, resulting in four mining companies. Hypotheses were tested using the Paired Samples t-Test and the Wilcoxon Signed Ranks Test. The empirical results indicate that internal fundamental performance, represented by CR, ROA, and DER, remained relatively stable with no significant changes. However, operational activity (TATO) and market valuation (PER) exhibited structural shifts following the event. These findings imply that management should adopt a dynamic approach in optimizing asset utilization and managing stock market sentiment to maintain corporate performance and investor confidence.
