GRI 2-24: Embedding policy commitments
a. Describe how it embeds each of its policy commitments for responsible business conduct throughout its activities and business relationships, including:
i. How it allocates responsibility 1. It is part of the BoD’s roles and responsibilities to oversee the implementation of the policy commitments. This is stated as follows:
to implement the commitments • MedcoEnergi’s Sustainability Manual (October 2022), pages 8–10 of 20, within the Sustainability Governance section: Structure & Oversight, and Roles & Responsibilities.
across different levels within the • Code of Conduct (page 5):
organization MedcoEnergi defines a set of standards to govern the conduct of the Board of Commissioners, Board of Directors, and all employees for the good and safety of all parties, as well as to achieve
an effective and efficient business operation conducted in accordance with all applicable laws and regulations.”
This statement aligns with the 2024 Sustainability Report (page 52): “Pursuing Excellence in Our Governance”, and the 2024 Annual Report (pages 98–101): “Corporate Governance.
2. There are various divisions in the organisation with day-to-day responsibilities for implementing each of the policy commitments. This is officially stated in the following documents:
• MedcoEnergi’s Sustainability Manual (October 2022), pages 10–20 of 20, within the Sustainability Governance section: Structure & Oversight, and Roles & Responsibilities for cross-functional
divisions, and Appendix E (page 18 of 20) for ESG Governance.
• To support MedcoEnergi’s best interests, Our Code must be communicated to, implemented by, and followed by all stakeholders, including the Board of Commissioners, Board of Directors,
employees, affiliates, business partners, and guests of the Company, without exception and regardless of their geographical locations (CoC, page 5).

partners. The activities and outcomes are reported to the GCG (Good Corporate Governance) Committee (for BoC and BoD) by the Audit and Integrity Compliance (AIC) Division.
5. The Corporate Ethics and Compliance Committee (CECC) was established in October 2024 to ensure objective and fair processes in addressing all reported incidents, and to align with legal
requirements, industry standards and international best practices. All allegation reports received through whistleblowing channels were promptly followed up by applying the principles of trust,
impartiality and protection. MedcoEnergi determined appropriate and consistent disciplinary actions in accordance with our procedures for addressing allegation reports. These procedures
involved a thorough review by the Ethics and Compliance Committee, consisting of the Board of Directors (BoD) level, Senior Vice President Business Support, the Head of Corporate A&IC, HR,
Legal and other relevant functions, as deemed necessary. This information can be accessed at:

2023:
Medco Power has identified work-related hazards. In the process of identifying potential hazards in the work environment, Medco Power utilizes the HIRADC (Hazard Identification Risk Assessment and
Determine Control) method. HIRADC is established before commencement of any work and is updated regularly, especially when there are new activities in the work process. By performing HIRADC,
it may minimize the occurrence of work accidents. This is evidenced by the absence of high-consequence injury throughout 2023 at Medco Power. There were several first aid cases, with the main
causes being the use of hand tools, slip, trip, and fall (STF) where this potential hazard has been classified into Life Saving Rules (LSR) related to line of fire, lifting, and working at height.
Medco Power encourages all leaders to make sure that everyone in their organisation is aware and understands the Life Saving Rules. Medco Power conducted regular review for hazard identification
and risk assessment to identify any potential hazards related to LSR which may cause high-consequence work accidents. Several actions were also conducted by Medco Power as a follow-up action and
prevention for reoccurring incidents, such as eliminating the risk by using safe and proper equipment, installing hazard or safety sign in strategic areas, providing procedures and working instructions for
safe work methods, providing proper personal protective equipment for all workers, and conducting mandatory HSE training for workers.
