Firm value is an important indicator for investors in assessing a company’s performance and future prospects. However, the declining company value in infrastructure sector and inconsistency of previous research results indicate the need for further study. This study examines the simultaneous and partial effects of Enterprise Risk Management (ERM), managerial ownership, firm size, and profitability on firm value. The research sample consists of 28 infrastructure companies listed on the IDX during the 2020-2024 period, selected through purposive sampling. The analysis method used is panel data regression with the help of EViews 12. The research results show thar ERM has a positive and significant effect on firm value, which means that good risk management can increase investor confidence and company performance. Meanwhile, managerial ownership and firm size has a negative and insignificant effect, so they have not been able to optimally increase firm value. Profitability has a positive but insignificant effect, indicating that profit alone is not strong enough to enhance firm value. The novelty of this study lies in testing the four variables simultaneously in the infrastructure sector using post-COVID-19 data, which reflects dynamic economic conditions. This study contributes to increasing understanding of the factors that influence firm value and serves as a consideration for companies in improving performance and investor confidence.
