This study analyzes the influence of mergers and acquisitions (M&A) on the financial performance of 15 non-financial companies on the Indonesia Stock Exchange for the period 2024-2025 using a descriptive quantitative method with secondary data from the annual financial statements measured through six ratios (ROA, ROE, NPM, CR, DER, and TATO) and tested using the Wilcoxon Signed Rank Test. The results showed that there was no significant difference in the overall financial ratio between the period before and after the M&A (p > 0.05), so that all six hypotheses were rejected, although descriptively 53.33% of companies showed an increase in ROA and ROE after M&A with the Raw Goods subsector showing performance improvement while Telecommunications and Energy experienced a decrease. These findings support the hubris theory and agency theory that M&A does not always create added value in the short term due to management overconfidence and opportunistic behavior, with limitations on short observation periods and small sample counts, so it is advisable for management to conduct comprehensive due diligence, for investors not to consider M&A as an automatic signal to invest, and for regulators to increase transparency of information on the realization of M&A synergies.
