PT Alamtri Resources Indonesia Tbk Overview

As the world's sixth-largest coal miner, it completed a thermal coal spin-off in December 2024. The company operates a diversified portfolio spanning metallurgical coal, minerals, renewable energy, and power generation across Southeast Asia and Australia.
Strategic Profile
Pro stress-test →In 2022, the company reorganized into three growth pillars: Adaro Energy (coal and power), Adaro Minerals (metallurgical coal and mineral processing), and Adaro Green (renewable energy). The company has committed to boosting non-coal revenue to over 50% by decade's end and keeping fossil fuel output flat. This positions Alamtri to navigate energy transition pressures while maintaining core coal operations, though the strategy's authenticity remains contested by ESG advocates.
