Objective: The purpose of this study is to propose a conceptual framework that investigates the impact of corporate governance practices on shareholder value. Theoretical framework: The proposed framework of this study is established based on agency theory and stewardship theory to establish the interrelationships among the models in this study. Method: In line with previous research, corporate governance practices have been shown to improve information disclosure through voluntary disclosure. Result and conclusion: This leads to maximizing the shareholders' value, as discussed in this paper. Financial leverage as a moderator factor is found to be a potentially significant factor in strengthening the effect of voluntary disclosure of information on the shareholders' value. Conclusion: Corporate governance practices play a pivotal role in enhancing shareholder value, especially when considering the influence of voluntary disclosure and the moderating effect of financial leverage. Originality/Value: The unique contribution of this research lies in its comprehensive analysis of the relationships between corporate governance practices, voluntary information disclosure, financial leverage, and their combined influence on shareholder value.
