This study examines whether Sustainability Reporting (SR) contributes to the financial performance indicators of Saudi listed firms. The study’s data are imperiled to regression analysis using the econometric model in computing the Tobin’s Q value as proposed under the section on study variables. It also examines the value significance of SR on financial performance among the listed firms in Tadawul by determining whether Tobin’s Q is statistically significant by specific firm’s attributes, including firm size, leverage, and EPS. The outcomes indicate that Tobin’s Q is statistically significantly influenced by leverage, EPS and firm size. Additionally, the study validates that no correlation occurs between the SR practices of the listed firms in Tadawul and the corporate financial performance.
