<![CDATA[Research aims: This study analyzes the mediating role of sustainability reports in the influence of CEO Power and corporate reputation on firm value in the energy sectors of Indonesia and Malaysia. Design/Methodology/Approach: This study employs a quantitative approach using secondary data from energy companies listed on the Indonesia Stock Exchange (IDX) and Bursa Malaysia (BM) for the period 2022–2024. Research findings: CEO Power and corporate reputation positively influence firm value, whereas only corporate reputation increases sustainability reporting. Sustainability Reports negatively affect firm value. As a result, Sustainability Reports do not mediate the relationship between CEO Power or corporate reputation and firm value. Theoretical contribution/Originality: This study reinforces Signaling and Stakeholder theories by showing how CEO Power and corporate reputation affect firm value, while Agency Theory explains the negative impact of Sustainability Reports. Practitioner/Policy implication: The practical contribution of this study is to provide companies, regulators, and investors with insights into the importance of CEO characteristics, corporate reputation, and the quality of Sustainability Reports in enhancing firm value. Research Limitations/Implications: This study has several limitations. The sample is restricted to energy companies in Indonesia and Malaysia during 2022–2024. Future studies are encouraged to expand the scope across sectors and countries and consider additional variables or mixed-method approaches for deeper insights.]]>
