                           MedcoEnergi Signs Multi-Party Domestic Gas Swap Agreement

Jakarta, 21 May 2025 – PT Medco Energi Internasional Tbk (MedcoEnergi) through its subsidiaries Medco
E&P Natuna Ltd. and Medco E&P Grissik Ltd., has signed a Domestic Gas Swap Agreement during the
49th Indonesian Petroleum Association Convention and Exhibition (IPA Convex) held at ICE BSD,
Tangerang.

Medco E&P Natuna Ltd. which is part of the West Natuna Group Supply Group - comprising South Natuna
Sea Block B, Natuna Sea Block A and Kakap PSCs -- and Medco E&P Grissik Ltd. as one of the gas
suppliers to Gas Supply Pte Ltd. from the Corridor Block and Jabung PSC (South Sumatra Sellers), have
signed the agreement together with several key parties. These include PT Pertamina (Persero), Premier
Oil Natuna Sea B.V., Star Energy (Kakap) Ltd., Sembcorp Gas Pte Ltd., Gas Supply Pte Ltd., Petrochina
International Jabung Ltd. and PT Perusahaan Gas Negara (Persero) Tbk (PGN). In addition to the swap
agreement, Medco E&P Natuna Ltd. with Premier Oil Natuna Sea B.V., and Star Energy (Kakap) Ltd. also
signed a separate Domestic Gas Sales Agreement with PGN.

Under the agreement, specific gas volumes will be supplied to Singapore from the West Natuna Supply
Group, replacing volumes currently delivered from the South Sumatra Sellers. These redirected volumes
will then be allocated to meet domestic gas demands with PGN serving as the domestic buyer.

SKK Migas, as the initiator and coordinator, led the multi-party discussions to address a potential gas
supply gap anticipated in the second half of 2025. Developed under its guidance, the agreement aims to
protect the interests of all participating parties.

Director and Chief Operating Officer of MedcoEnergi, Ronald Gunawan, stated that MedcoEnergi’s
participation in this arrangement reflects its strong commitment to national energy security through
collaborative and balanced supply solutions. “This collaboration demonstrates a strong example of
productive synergy between upstream operators, the regulator, partners and buyers in ensuring gas
supply across both domestic and international markets,” said Ronald Gunawan.
