         MedcoEnergi Announces Hydrocarbon Discovery at West Kalabau-1 Exploration Well

Jakarta, 3 March 2025– PT Medco Energi Internasional Tbk (“MedcoEnergi”) through its subsidiary PT
Medco E & P Rimau, has successfully made a hydrocarbon discovery at the West Kalabau-1 exploration
well, located in the Rimau Block, South Sumatra, Indonesia. This positive result further strengthens
MedcoEnergi’s commitment to sustaining Indonesia’s energy production by optimizing the potential of its
assets.

The West Kalabau-1 well was drilled to a total depth of approximately 3,220 ft, targeting the Baturaja
Formation, a proven reservoir in the region. Formation evaluation and initial analysis confirmed the
presence of hydrocarbons, providing a strong basis for further development planning.

West Kalabau-1 highlights the untapped potential that remains within Indonesia’s mature basins. This
achievement reflects MedcoEnergi’s continued focus on delivering safe, efficient, and responsible
exploration and production activities. We will work closely with SKK Migas to further evaluate the
commercial potential of this discovery."

MedcoEnergi, together with SKK Migas, will proceed with additional well testing and technical evaluations
to further assess the potential size and commercial viability of the discovery, which will guide future
development activities.
