This study used the long-term pre and post-merger financial data to investigate the long-term performance. The present work conducted a comprehensive ratio analysis of 14 major ratios related to profitability, efficiency, leverage, and liquidity. The method used in testing the research was a quantitative approach with paired t-test and Wilcoxon test. The results of this study show that financial performance after the merger and acquisition (M&A) was better than before.
