What BUMA International Group does

BUMA International Group (PT BUMA Internasional Grup Tbk, IDX: DOID) is an Indonesia-based mining holding group that has evolved from a single-country coal mining contractor into a diversified mining services and ownership platform spanning three countries. Founded in 1990 and listed on the Indonesia Stock Exchange since 2001 (renamed from Delta Dunia Group in 2025), the group operates through five principal subsidiaries: BUMA (Indonesia's largest independent coal mining contractor with ~15% market share, established 1998), BUMA Australia (acquired in 2021 from Downer EDI's Open Cut Mining East business, operating across Queensland's Bowen Basin including Goonyella Riverside, Blackwater, and Meandu), Atlantic Carbon Group (71%-owned U.S. ultra-high-grade anthracite producer in Pennsylvania, acquired June 2024), BTech (mining technology subsidiary established 2023), and BIRU (social enterprise for vocational training and circular economy, established 2023). The group also holds strategic equity stakes in 29Metals (22.60%) and Asiamet Resources (44.15%), providing exposure to copper and base metals.

The core business model is contract mining: BUMA and BUMA Australia deliver overburden removal, coal mining, transportation, and reclamation services under multi-year, volume- and coal-price-indexed contracts with major thermal and metallurgical coal producers, including Adaro, Bayan Group, Berau Coal, Geo Energy, PT Persada Kapuas Prima, Whitehaven Coal, BHP Mitsubishi Alliance, Stanwell Corporation, and Bowen Coking Coal. FY2025 production reached 439 million BCM of overburden and 84 million tonnes of coal. The technology arm BTech layers asset management, safety/health/environment (SHERA), HR management, and mining engineering solutions, with machine learning applied to equipment health monitoring and digital workflow automation across a fleet of 3,000+ heavy equipment units. Revenue is generated primarily through transaction-fee-based mining services contracts; technology solutions operate on a SaaS/consulting basis, while the BIRU social enterprise contributes professional services revenue. FY2025 consolidated revenue was US$1.48 billion with US$175 million EBITDA (14% margin), and 1Q26 revenue of US$318 million with US$28 million EBITDA showed year-on-year operational recovery.

Others

• PT Bukit Asam: Indonesian state-owned coal miner. Potential BUMA customer/partner rather than direct competitor; provides a benchmark for Indonesian coal industry dynamics and customer-side economics.
• PT Adaro Energy: One of BUMA's largest Indonesian coal mining customers (South Tutupan contract through 2030). Not a direct competitor but represents the customer-side concentration and coal-market dynamics that drive BUMA's revenue trajectory.

Broad incumbents

• Komatsu: Global mining and construction equipment manufacturer, the dominant supplier of heavy mining equipment used by BUMA's fleet. Adjacent to BUMA's contractor operations, with growing autonomous mining technology that competes with BTech's offerings.
• Caterpillar: Global OEM of mining and construction equipment, including the heavy machinery fleet (Komatsu/Cat) that BUMA operates. Adjacent rather than competing, but a key supplier and benchmark for mining services productivity.
• PT United Tractors: Indonesia's largest heavy equipment distributor (Komatsu) and a major mining services contractor through its PAMA subsidiary. Competes with BUMA in the Indonesian coal contracting market but with a much broader heavy-equipment distribution franchise.
• CIMIC Group: Parent company of Thiess, with diversified construction, mining, and services operations. Broader portfolio than BUMA but its mining services arm is the closest large-scale competitor to BUMA Australia.
• Downer EDI: Australian infrastructure and mining services group that sold its Open Cut Mining East business to BUMA in 2021. Former direct competitor; now operates in adjacent transport/services infrastructure while BUMA inherited the mining contracting assets and customer contracts.

Direct peers

• Macmahon Holdings: Australian-listed mining contractor with surface and underground operations across Australia and Indonesia. Closely mirrors BUMA's contractor business model across the same geographic footprint.
• Perenti Group (Barminco / Ausdrill): Diversified mining services contractor offering surface, underground, and drilling services globally. Comparable contract-mining business model with similar equipment-intensive operations and tier-1 mining customers.
• Thiess: Australia's largest mining services contractor (subsidiary of CIMIC Group). Directly comparable to BUMA Australia, competing for the same large coal and metallurgical mining contracts (e.g., BMA, Whitehaven, Anglo American assets).
