    BUMA Secures Contract with Adaro for South Tutupan Mine through 2030

Jakarta, February 23, 2026 – PT Bukit Makmur Mandiri Utama (“BUMA”), the principal subsidiary of PT
BUMA Internasional Grup Tbk (IDX: DOID; “BUMA International Group”), today announced a long-
term contract with PT Adaro Indonesia (“Adaro”). The contract, effective from April 1, 2026 through
December 31, 2030, secures BUMA's operations at the South Tutupan Mine in Tanjung Tabalong, South
Kalimantan.

Under the contract, subject to the terms and conditions contained therein, BUMA is expected to deliver
around 239 million bank cubic meters (bcm) of overburden removal and 44 million tonnes of coal,
equivalent to average annual volumes of 50.5 million bcm and 9.3 million tonnes, respectively. The
contract reinforces BUMA’s long-standing partnership spanning over 20 years with Adaro, while
strengthening the Group’s contracted revenue base and long-term earnings visibility.

Ronald Sutardja, President Director of PT Bukit Makmur Mandiri Utama, stated, “We are pleased to
announce this significant contract with Adaro Indonesia, one of our valued long-term partners. The
contract is a testament to BUMA’s consistent operational delivery and our ability to manage technically
complex mining operations safely and reliably. It strengthens our contracted earnings visibility and
reinforces our position as Indonesia's trusted mining services partner."

In parallel with its operational activities, BUMA is deeply committed to empowering local communities
in the Tabalong through programs focusing on education, health, environmental protection, and socio-
cultural initiatives. Key initiatives include the JIKAMAKA computer skills workshop, Youth Broadcasting
Class for creative industry development, the Kampung Iklim environmental program, and support for
local small and medium enterprises (UMKM).

These efforts have earned recognition from the South Kalimantan Provincial Government for
environmental contributions, appreciation from the Tabalong Regent for advancing the Adipura
initiative and UMKM development, as well as commendation from the Tabalong Youth Community and
the Regent for consistent support of youth and community development programs.

"Our partnership with Adaro Indonesia extends beyond operational delivery to creating shared value for
local communities. We are proud of the positive social impact we have created together and will
continue investing in the community's long-term prosperity,” Ronald concluded.
