Management’s responsibilities
The Group’s management is responsible for selecting the Criteria, and for preparing and
presenting the accompanying Subject Matter Information in accordance with the Criteria, in all
material respects. This responsibility includes establishing and maintaining internal controls,
maintaining adequate records and making estimates that are relevant to the preparation and
presentation of the Subject Matter Information that it is free from material misstatement,
whether due to fraud or error.
Independent practitioner’s responsibility
Our responsibility is to express a conclusion on the preparation and presentation of the
accompanying Subject Matter Information based on the sufficient and appropriate evidence we
have obtained during our Engagement.
We conducted our Engagement in accordance with the Professional Standards established by
the IICPA, and the terms of reference for this Engagement as agreed with the Group’s
management. Those standards require that we plan and perform our Engagement to express a
conclusion on whether anything has come to our attention that causes us to believe that the
accompanying Subject Matter Information has not been prepared and presented, in all material
respects, in accordance with the Criteria. The nature, timing, and extent of the procedures
selected depend on our professional judgment, including an assessment of the risk of material
misstatement, whether due to fraud or error.
We believe that the evidence we have obtained is sufficient and appropriate to provide a basis
for our limited assurance conclusion.
Independent practitioner’s independence and quality management
We have complied with the independence and other relevant ethical requirements of the Code
of Ethics for Public Accountants issued by the IICPA, which is founded on fundamental ethic
principles of integrity, objectivity, professional competence and due care, confidentiality and
professional behavior.
Our Public Accounting Firm applies Standard on Quality Management 1, “Quality Management
for Public Accounting Firms that Perform Audits or Reviews of Financial Statements, or Other
Assurance or Related Services Engagements”, established by the IICPA, which requires our
Public Accounting Firm to design, implement and operate a system of quality management
including policies or procedures regarding compliance with ethical requirements, professional

Report No. 00011/2.1505/NS.0/02/0696-2/1/IV/2026 (continued)
Description of procedures performed
Procedures performed in a limited assurance engagement vary in nature and timing from and
are less in extent than for a reasonable assurance engagement. Consequently, the level of
assurance obtained in a limited assurance engagement is substantially lower than the assurance
that would have been obtained had a reasonable assurance engagement been performed. Our
procedures were designed to obtain a limited level of assurance on which to base our conclusion
and do not provide all the evidence that would be required to provide a reasonable level of
assurance.
Although we considered the effectiveness of management’s internal controls when determining
the nature and extent of our procedures, our assurance engagement was not designed to
provide assurance on internal controls. Our procedures did not include testing controls or
performing procedures relating to checking aggregation or calculation of data within
information technology systems.
A limited assurance engagement consists of making enquiries, primarily of persons responsible
for preparing and presenting the accompanying Subject Matter Information and related
information, and applying analytical and other appropriate procedures.
Our procedures included:
Enquiring key personnel to understand the process for collecting, collating and reporting the
Subject Matter Information during the reporting period.
Performing analytical review procedures to support the reasonableness of the data used.
Comparing that the calculation criteria applied to the subject matters in accordance with the
methodologies outlined in the Criteria.
Recalculating the performance metrics to confirm quantities that are stated as replicable.
Checking the accuracy of data used by tracing them to the underlying source information on
a sample basis.
Undertaking site visits to oil and gas operation location, Corridor-Grissik, and to power
operation location, Mitra Energi Batam (MEB) and Dalle Energi Batam (DEB)

risks using the hierarchy of controls (GRI 403-9)
The risk assessment process is conducted with
participation of multidisciplinary teams with
objective to eliminate or minimize potential
major hazard accident occurrence and reduce
the risk within operations. The process is
conducted by demonstrating risk reduction
measures and giving confidence that asset has
the ability and means to manage their hazard
and control potential major accident risk
properly, to achieve safe, and sustainable
operations.
Throughout 2025, there is no high-
consequence injury from operational activities
recorded in the Oil & Gas operations.
Identified hazards that pose a risk of high-
consequence injury are:
• Well activities causing potential blow
out
• Loss of containment from
hydrocarbon processing facility
• Gas blowby in the processing facility
• Toxic gas exposure due to loss of
primary containment
• Aviation operation
• Marine operation, including potential
vessel collision with facility and boat
transfer
• Land transportation
• Use of explosive material and
detonator to support activity
• Pressurized gas cylinder
• Lifting activity
• Forest fire
• Electrocution
Power Medco Power has identified work-related
(Indonesia) hazards for power plant operation and project.
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. However, several medical treatment
cases occurred, primarily caused by exposure
to heavy equipment and contact with burned
coal materials. These hazards fall under the
Life Saving Rules (LSR), specifically related to
line-of-fire risks and hot work activities.
Medco Power encourages all leaders to make
sure that everyone 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, developing work
procedures and instructions for safe work
methods, providing appropriate personal
protective equipment for all workers,
increasing Life Saving Rules safety awareness,
and conducting mandatory HSE training for all
workers.
