PT Bayan Resources Tbk : Investor Updates 1Q25

About this update from Pt Bayan Resources Tbk

www.bayan.com.sg 0 Operationally, we achieved a significant increase in sales volume in the 1Q25 compared to 1Q24, although production levels were lower than Budgeted caused by heavier than anticipated rainfall. Overall 1Q25 EBITDA and NPAT actual performance was lower than Budgeted which was principally due to lower ASP. Despite this, 1Q25 financial performance is still generating very healthy margins and profit levels. 2023 2024 1Q24 1Q25 Financial Performance (In Million USD) Revenue 3,581.4 3,446.2 769.1 890.1 Gross Profit 1,664.2 1,332.8 312.2 315.2 EBITDA 1,718.9 1,355.0 322.1 327.5 Net Profit After Tax 1,279.6 943.4 217.3 223.0 Financial Ratios Gross Profit Margin (%) 46.5% 38.7% 40.6% 35.4% EBITDA Margin (%) 48.0% 39.3% 41.9% 36.8% Net Profit Margin (%) 35.7% 27.4% 28.2% 25.0% Net Debt to EBITDA (x) Net Cash Net Cash Net Cash Net Cash Operational Statistics Overburden Removal (MBCM) 219.5 257.5 62.0 69.9 Strip Ratio (x) - based on production volume 4.4 4.5 4.4 5.1 Coal Production (MT) 49.7 56.9 14.0 13.7 Sales Volume (MT) 47.2 56.2 12.2 17.2 Average Selling Price (US$/MT) 75.8 61.3 63.0 51.7 Average Cash Costs (US$/MT) 40.2 37.8 37.3 32.9 2024 Production Bayan is ranked 3rd by production 90 74.7 Million Tonnes 75 60 45 30 15 0 65.8 56.9 50.7 43.3 30.7 20.2 and by sales volumes in Indonesia based on 2024 actual performance.
