       MEDCOENERGI ENTRUSTED BY THE GOVERNMENT TO MANAGE NAWASENA BLOCK

Jakarta, May 20th 2026 - The Indonesian Government, through the Ministry of Energy and Mineral
Resources (KESDM), has entrusted PT Medco Energi Internasional Tbk (MedcoEnergi) with the
management of the Nawasena oil and gas Working Area. The signing of the Cooperation Contract was
announced during the 50th Indonesia Petroleum Association Convention and Exhibition at the Indonesia
Convention Exhibition (ICE), BSD City, on Wednesday (20/5).
The Nawasena Working Area covers approximately 7,031 km² of onshore and offshore territory in East
Java Province. Through its subsidiary, PT Medco Energi Nawasena, MedcoEnergi will act as the operator
under a Production Sharing Contract (PSC) cost recovery scheme.

Madura Offshore PSCs, enabling the rapid monetization of Nawasena’s resources through existing
infrastructure.

the trust given by the Indonesian Government and is committed to optimally developing the Nawasena
Working Area to support national energy security.” (***)
