State-controlled coal producer PT Bukit Asam Tbk (IDX: PTBA) reported higher coal production, sales, and transportation volumes in the first nine months of 2025, reflecting the company’s solid operational performance amid global market volatility.

PTBA produced 35.90 million tons of coal by the end of September 2025, up 9 percent year-on-year from 32.97 million tons in the same period last year. The company said the higher output was supported by increased contributions from its mining services subsidiary, PT Satria Bahana Sarana, which accounted for 21 percent of total production. The stripping ratio during the period was recorded at 5.98 times, the company said in a statement on Monday.

Coal sales rose 8 percent year-on-year to 33.70 million tons, compared with 31.28 million tons in the same period of 2024. The domestic market absorbed 56 percent of the total sales, while the remainder was exported. PTBA said the increase in sales volume demonstrated continued strong market demand for its coal.

In line with rising production and sales, PTBA’s coal transportation volume also grew 8 percent to 30.02 million tons, up from 27.83 million tons a year earlier. The company attributed the improvement to ongoing supply chain optimization and greater efficiency in logistics operations.

PTBA noted that signs of recovery in global coal prices began to emerge in mid-third quarter 2025, as reflected in the strengthening of the Indonesian Coal Index (ICI) through early fourth quarter. The company said it remains optimistic that its strong operational performance and efficiency measures will help cushion the impact of weaker coal prices seen earlier in the year and provide a solid base for stronger financial results by year-end.

PTBA said in June that it was aiming for coal production and sales of 50 million tons in 2025.
