<![CDATA[This research is motivated by the rapid development of the business world in the era of globalization, where increasingly intense competition requires companies not only to focus on profit generation but also to ensure business sustainability and enhance firm value. Consequently, companies must effectively manage their resources and financial performance to remain competitive and attract investor interest. This study aims to analyze the effect of profitability, leverage, and liquidity on firm value, with firm size serving as a moderating variable, focusing on manufacturing companies listed on the Indonesia Stock Exchange (IDX) during the 2024–2025 period. This study employs a quantitative causal research method. The population consists of 228 manufacturing companies listed on the IDX, with 88 companies selected as samples using purposive sampling over a two-year observation period. Data analysis includes classical assumption tests, moderated regression analysis, the coefficient of determination test, and hypothesis testing using SPSS version 23. The results indicate that profitability and liquidity have a significant effect on firm value, whereas leverage does not. Furthermore, firm size moderates the relationship between profitability and firm value as well as between liquidity and firm value, but does not moderate the relationship between leverage and firm value. The implications of this study indicate that financial performance indicators influence firm value; therefore, investors can use this information as a basis for evaluating companies and making investment decisions.]]>
