What Alamtri Resources Indonesia Tbk does

PT Alamtri Resources Indonesia Tbk (formerly PT Adaro Energy Indonesia Tbk) is an Indonesian integrated mining and energy group listed on the Indonesia Stock Exchange (ticker: ADRO), headquartered in Jakarta. The company operates a vertically integrated platform spanning thermal coal mining (through PT Adaro Indonesia and its South Tutupan operations in South Kalimantan), metallurgical coal and mineral processing (through PT Alamtri Minerals Indonesia Tbk), contract mining services, coal logistics and barging, and coal-fired power generation (through PT Tanjung Power Indonesia, with 2x1,000 MW PPAs with PLN). Following a 2023–2024 corporate rebrand, the Group has articulated a strategic pivot toward non-thermal coal businesses, targeting more than 50% of revenue from metallurgical coal, aluminum smelting, mineral processing, and renewable energy by 2030, complemented by nature-based carbon projects (PT Alam Sukses Lestari / BLFRP ~19,059 Ha and PT Hutan Amanah Lestari / BLPP ~25,804 Ha) and an independent Deloitte-managed whistleblowing system, with OHS certified to ISO 45001:2018 across the Group. Customers are industrial counterparties — steel mills for metallurgical coal, PLN and other power utilities for thermal coal, and mining operators such as BUMA for contract mining services — served through enterprise field sales and long-term offtake agreements.

The Group monetizes its portfolio through long-term contracts with industrial offtakers, supplemented by recurring renewable-energy power sales once projects are commissioned. FY2025 revenue was US$1,874M with EBITDA of US$799M (43% margin) and net profit of US$490M; production volume grew from 5.11 Mt (2023) to 7.41 Mt (2025) and sales reached 6.28 Mt, while dividends totaled US$500M for FY24 (36.23% payout) plus a US$250M interim for FY25. Go-to-market is enterprise field-sales led, supported by an event-driven investor relations programme (annual Public Expose sessions, sustainability and annual report launches) and broad sell-side coverage of 35 analysts across Indonesian and global brokerages. Governance is anchored by a Sustainability Management Committee, a Carbon Reduction Roadmap evaluated across 11 subsidiaries, and a phased NZE roadmap targeting 2060 or earlier, aligned to Indonesian SFAS standards and the UN SDGs.

Underlying technology centers on integrated open-pit mining with in-house barging and port logistics, coal-fired power generation assets, and operational decarbonization systems including B35 biodiesel adoption (delivering a 34.98% GHG reduction versus pure diesel since 2013), solar PV generation (up to 749,294 kWh/year planned, scaling to 8 MWp), a Continuous Emissions Monitoring System integrated with Indonesia's Ministry of Environment and Forestry via the SISPEK reporting platform, electrostatic precipitators at the MSW facility, and co-firing trials with organic waste pellets. Non-thermal growth pillars under development include the Green Aluminum Project (announced December 2021), the PLTA Mentarang Induk hydroelectric power plant (groundbreaking March 2023) under PT Alamtri Renewables Indonesia, and an internal waste-data platform called Adaropedia that supports the Group's 3R (reduce, reuse, recycle) waste management approach.

Revenue model

1. Thermal Coal Sales: Sale of thermal coal produced through subsidiaries (historically PT Adaro Indonesia); 2025 revenue $1,874M and 2025 sales volume 6.28 Mt — the legacy revenue pillar now being separated from thermal coal mining entities under the ESG strategy.
2. Metallurgical Coal and Minerals Sales: Sales of metallurgical coal for steelmaking plus mineral processing through PT Alamtri Minerals Indonesia Tbk and subsidiaries — strategic growth pillar as the company targets ~50% of revenue from non-thermal coal businesses by 2030.
3. Mining Services Contracts: Contract mining services delivered through subsidiaries (e.g., contract mining via the Adaro Services pillar); example contract covers removal of ~239 million bank cubic metres of overburden and extraction of 44 million tonnes of coal (April 2026 – December 2030).
4. Aluminum Smelting (Green Aluminum Project): Planned/under-development aluminum smelting project (Green Aluminum Project announced 2021) intended to drive non-thermal coal revenue mix and support Indonesia's downstream manufacturing ambitions.
5. Renewable Energy Power Generation: Renewable energy (solar, hydro) power generation through PT Alamtri Renewables Indonesia; in development as part of NZE-aligned portfolio diversification.
6. Barging and Coal Logistics Services: Historical barging/logistics services via subsidiaries including PT Maritim Barito Perkasa (MBP), which secured a US$160 million seven-year bank loan in 2012 for fleet expansion.

Core offering

PT Alamtri Resources Indonesia Tbk is an integrated Indonesian mining and energy group that produces and sells thermal coal (via PT Adaro Indonesia) and metallurgical coal (via PT Alamtri Minerals Indonesia), delivers contract mining services such as overburden removal and coal extraction, and operates coal-fired power generation under long-term Power Purchase Agreements. The group is also developing renewable energy (solar PV and hydro via PT Alamtri Renewables Indonesia) and a planned Green Aluminum smelting project as part of its non-thermal coal growth strategy.

Product overview

PT Alamtri Resources Indonesia Tbk is an integrated mining and energy platform rather than a single product, operating through a group of subsidiaries and strategic pillars. Its core thermal coal operations are run through PT Adaro Indonesia, while the non-thermal coal growth engine is delivered through PT Alamtri Minerals Indonesia Tbk (metallurgical coal, aluminum smelter, and green minerals), PT Alamtri Renewables Indonesia (solar PV and hydro, including PLTA Mentarang Induk), and the Adaro Green and Adaro Minerals strategic pillars. The Group also manages nature-based carbon projects (PT Alam Sukses Lestari / BLFRP and PT Hutan Amanah Lestari / BLPP) and an internal waste-data platform called Adaropedia, all coordinated under a corporate-wide ESG / Net Zero Emissions roadmap.
