                 MedcoEnergi Installs 1,500 Solar Panels in Corridor Block, Reduces Emissions by
                                            934 Tons of CO₂e Annually

Jakarta, 8 September 2025 – PT Medco Energi Internasional Tbk (“MedcoEnergi”), through its subsidiary Medco
E&P Grissik Ltd., has reaffirmed its commitment to sustainability by installing rooftop solar power systems across
the Corridor Block working area. The installation of 1,500 solar panels is expected to reduce carbon emissions by
up to 934 tons of CO₂ equivalent (CO₂e) per year, underscoring MedcoEnergi’s tangible efforts in supporting the
energy transition.

With a total capacity of 885 KWp, the rooftop solar PV systems operate across the Suban, Grissik, Dayung, and
Sumpal areas. They are projected to generate more than 1,124 MWh peak of clean electricity annually. In addition
to reducing gas consumption by approximately 18 MMscf per year, this initiative also cuts carbon emissions
equivalent to those generated by a vehicle traveling up to 5.5 million kilometers annually.

Ronald Gunawan, Director & Chief Operating Officer of MedcoEnergi, stated, “This project demonstrates that
renewable energy can go hand in hand with upstream oil and gas operations. It is more than just a technological
installation, it is a concrete step toward operational efficiency and carbon footprint reduction.”

This initiative is part of MedcoEnergi’s long-term strategy to integrate sustainability principles across its business
value chain. The Company continues to drive energy efficiency, low-carbon energy development, and greenhouse
gas emission reductions, through solar power projects, geothermal energy, and other emission reduction initiatives
across its operations. This commitment also reflects MedcoEnergi’s active role as a key player in the national energy
sector in supporting the Government’s Net-Zero Emission targets and addressing the global call for a just and
sustainable energy transition.

“For us, sustainability is not a short-term project but a long-term commitment. MedcoEnergi will continue to
strengthen its role as a national energy company that is not only operationally reliable, but also accountable for the
future of the environment and generations to come,” Ronald added.
