Copper Giant’s Growing Pains: Amman Mineral Weathers a Transitional 2025 to Target a 2026 Rebound

JAKARTA, Investortrust.id — PT Amman Mineral Internasional Tbk (AMMN), Indonesia’s second-largest copper and gold producer, is navigating the final bends of a complex industrial transformation. In its 2025 fiscal report released Thursday, the company revealed a net profit of $258.03 million—a 59.78% decline from the $641.67 million recorded in 2024. While the headline figures reflect a cooling period, the underlying narrative is one of a coiled spring, as the firm sacrifices short-term volumes to solidify its status as a fully integrated global metals powerhouse.

The dip in earnings follows a planned contraction in net sales, which landed at $1.84 billion compared to the previous year’s $2.66 billion. Despite the top-line pressure, Amman maintained a robust EBITDA margin of 57%, signaling that the company’s core operational efficiency remains intact even as it maneuvers through its Phase 8 mining expansion and the ramp-up of its domestic smelting facilities.

For the global commodities market, Amman’s performance is a bellwether for Indonesia’s "downstreaming" ambitions—a state-mandated shift to process raw ores into high-value metals within national borders. By successfully producing its first copper cathodes and refined gold in 2025, Amman has moved beyond being a mere excavator of earth to become a manufacturer of the high-purity materials essential for the global energy transition.

The Phase 8 Pivot

The primary catalyst for the 2025 contraction was the transition to Phase 8 at the Batu Hijau mine. During this stage, miners must work through lower-grade ore—essentially "clearing the deck" before reaching the richer deposits expected in the near future. Consequently, copper production fell 47% to 209 million pounds, while gold output dropped 87% to 102,758 ounces.

"2025 was a pivotal transition year for Amman," said President Director Arief Sidarto. "The shift to Phase 8 mining, characterized by lower ore grades, coincided with our smelter capacity ramp-up, creating short-term operational pressure. However, we have achieved various strategic milestones, completing our transformation into a fully integrated copper and gold producer."

Refining the Future

Beyond the pits of Sumbawa, the company’s smelting operations faced their own set of teething issues. Facilities were briefly shuttered in July and August for maintenance on the Flash Converting Furnace and the Sulfuric Acid Plant. However, the company reports that operations stabilized by the fourth quarter, coinciding with the receipt of a crucial six-month export permit for 480,000 dry metric tons of concentrate. This permit provides a vital "safety valve," allowing the company to monetize its inventory while the domestic smelter reaches full throttle.

Financial health remains a priority as the company fuels this growth. Total debt rose 50% to $6.43 billion to fund massive capital expenditures, including a 450 MW gas-and-steam power plant and LNG regasification facilities. With a cash reserve of $677 million, the company is betting heavily that its infrastructure investments will pay dividends as global copper demand—driven by electric vehicles and renewable grids—continues to outpace supply.

2026: The Year of the Leap

The "short-term pain" of 2025 appears to be setting the stage for a spectacular "long-term gain." Management has issued an ambitious target for 2026, aiming to double concentrate production to 900,000 tons—a 101% increase over 2025 levels. This surge is expected to yield 485 million pounds of copper and 579,000 ounces of gold.

While execution risks remain—particularly regarding the commissioning of new concentrator plants—the company's leadership remains steadfast. "Despite short-term challenges, the long-term fundamentals for copper and gold remain exceptionally strong," Arief noted. With the heavy lifting of the smelter integration largely complete, Amman is positioned to ride the next commodities upswing with a leaner, more vertically integrated business model.
