Investor relations and corporate governance are critical components in ensuring the sustainable development and operational efficiency of companies within the global energy sector. This theoretical review explores the best practices in investor relations and corporate governance, particularly focusing on their application within emerging economies. The global energy sector is highly capital-intensive, requiring robust governance structures to manage risks, ensure transparency, and align the interests of stakeholders. Effective investor relations strategies foster trust, provide timely and accurate information, and enhance shareholder engagement, all of which are essential for securing long-term investments in energy projects. Corporate governance, on the other hand, ensures accountability, compliance with regulatory frameworks, and ethical management practices. The review highlights best practices in corporate governance, including the establishment of independent boards, strong leadership, risk management frameworks, and the importance of environmental, social, and governance (ESG) criteria in decision-making processes. In terms of investor relations, strategies such as proactive communication, regular financial disclosures, and engagement with both institutional and retail investors are identified as key to maintaining investor confidence. In emerging economies, where energy needs are rapidly increasing, the application of these best practices presents both challenges and opportunities. Regulatory frameworks in these regions are often evolving, and companies must navigate complex political and economic environments while adhering to global standards. This review discusses how emerging markets can benefit from adopting globally recognized governance and investor relations practices to attract foreign investment and foster sustainable energy development. The theoretical insights presented offer a comprehensive understanding of the interplay between investor relations and corporate governance in the energy sector. Additionally, this review underscores the importance of adaptability and innovation in applying these best practices to the unique contexts of emerging economies..
