The purpose of this research is to determine the direct influence of capital structure, corporate social responsibility, and financial performance on business value, as well as if financial performance acts as a mediating element between capital structure and CSR. This study examines metal industrial sector manufacturing firms that are publicly traded on the Indonesian Stock Exchange through the use of secondary data, data collection, and documentation (IDX). The study sampled 14 businesses using purposive sampling, and the sample comprised 56 financial reports covering four years. Capital structure variables are determined using DER, CSR variables are determined using GRI-G4 principles, financial performance is determined using ROA, and firm value is determined using PBV. To test hypotheses, Path Analysis was employed. According to the findings, capital structure had a positive but minor effect on financial performance, CSR had a significant positive effect on financial performance, and capital structure had a large positive effect on business value. Financial performance has a significant negative effect on corporate value, but CSR has a tiny but favourable effect. Financial performance acts as a buffer between CSR and business value, rather than between capital structure and company value.
