What Terrafame does

Terrafame Ltd is a Finnish multi-metal and battery chemicals producer operating a fully integrated industrial site in Sotkamo, Finland, comprising an open-pit mine, metals recovery plant, battery chemicals plant, and uranium recovery plant. The company employs approximately 887 staff directly (with roughly 1,800-2,000 total personnel on site including partner companies as of recent reporting) and was founded in 2015 after acquiring assets from the bankrupt Talvivaara operation. Its core technology is a proprietary bioleaching process that uses microbial activity to extract metals from low-concentration ore with 90% less energy consumption than conventional nickel production, yielding battery-grade nickel sulphate and cobalt sulphate with one of the lowest carbon footprints in the industry (1.6 CO2e/kg for nickel sulphate, 60% below the industry average verified by Sphera Solutions GmbH). Production capacity is sufficient for approximately one million electric vehicles per year. Beyond battery chemicals, Terrafame produces zinc sulphide, copper sulphide, ammonium sulphate as by-products, and began recovering natural uranium in June 2024 at a planned output of ~200 tonnes/year.

The company generates revenue through direct B2B enterprise sales of metals and chemicals to a concentrated base of European customers, led by long-term supply agreements with Renault Group (nickel sulphate for >200,000 EVs/year, signed 2021), Stellantis (signed January 2023), and Umicore (signed February 2023), with additional sales to metal processing and nuclear fuel customers. Pricing is quote-based and not publicly disclosed. Full-year 2025 net sales were EUR 556.1 million (+2.1% YoY), with EBITDA of EUR 79.5 million (+19.9% YoY, 14.3% margin) and an operating loss excluding non-recurring items of EUR -35.0 million. Ownership is anchored by state-owned Finnish Minerals Group (56.1%), with private equity Galena Funds (39.4%) and Mandatum (4.5%); Trafigura is a strategic partner and related party.

Terrafame is currently executing a 2026-2030 strategy centered on the LEACHMAX primary leaching capacity expansion (new heap 5 in production by early 2027), uranium revenue ramp, scandium pre-feasibility with Worley, and the Kolmisoppi second ore deposit (EU CRMA strategic project status, target mining start 2028). The Kolmisoppi project, combined with the Kuusilampi deposit, extends mine life beyond 30 years, reinforcing Terrafame's position as Europe's largest primary nickel producer (>70% of EU primary nickel) and the only EU producer of battery-grade nickel sulphate. Cost-side, change negotiations concluded in March 2026 with a reduction of up to 109 person-years and targeted savings of at least EUR 10 million annually, alongside a planned CEO-CFO transition (new CEO Antti Koulumies effective September 2025, new CFO Ilkka Pitkänen effective August 2026).

Revenue model

1. Battery Chemicals Sales: Production and sale of nickel sulphate and cobalt sulphate for electric vehicle batteries. Nickel sulphate capacity sufficient for approximately 1 million electric cars per year.
2. Uranium Recovery: Natural uranium recovered as by-product from ore extraction. After further refining abroad, used as fuel in nuclear energy production. Estimated to add EUR 30-40 million annually to net sales at full capacity.
3. Zinc and Copper Products: Intermediate zinc and copper sulphides sold to metal processing customers. Zinc sulphide has high zinc content, very low iron content and excellent solubility. Copper sulphide used in copper refining industry.
4. Ammonium Sulphate: By-product of battery chemicals plant, used as raw material for fertilizers and chemical industry.

Core offering

Terrafame operates an open-pit mine and integrated metals recovery and battery chemicals plant at a single industrial site in Sotkamo, Finland. Using proprietary bioleaching technology, it extracts nickel, cobalt, zinc, copper, and uranium from ore and converts most of its nickel and cobalt into battery-grade nickel sulphate and cobalt sulphate for electric vehicle batteries, with capacity sufficient for approximately one million EVs per year. Additional sellable outputs include intermediate zinc sulphide, copper sulphide, ammonium sulphate by-product, and recovered natural uranium.

Product overview

Terrafame is a fully integrated multi-metal producer and battery chemicals company operating from a single industrial site in Sotkamo, Finland. The company operates an open-pit mine with bioleaching-based metals extraction, producing both battery chemicals and intermediate metal products. Battery chemicals (nickel sulphate and cobalt sulphate) are produced at one of the world's largest battery chemicals plants for electric vehicles. Other products include zinc sulphide, copper sulphide (intermediates), ammonium sulphate (by-product), and natural uranium (by-product, started June 2024). The Kolmisoppi project represents a strategic expansion ore deposit. The entire production chain from mine to battery chemicals is integrated on one site, enabling full traceability and one of the smallest carbon footprints in the industry (60% lower than industry average).

Broad incumbents

• Anglo American: Diversified global miner with platinum group metals, copper, iron ore, and crop nutrients. Comparable as a major diversified mining incumbent with exposure to battery raw materials via its platinum and copper portfolios.
• Glencore: Global diversified mining and trading major with significant nickel and cobalt production. A broad incumbent in the same critical battery raw materials space, though operating at much greater scale and geographic reach than Terrafame.
• BHP: Global mining major with the Nickel West operation in Western Australia producing battery-grade nickel. A broad incumbent supplying similar battery raw materials but at far larger scale and across multiple commodity segments.
• Nornickel: World's largest refined nickel and palladium producer, headquartered in Russia. Operates as a broad incumbent supplying class-1 nickel into the global battery chemicals supply chain.

Direct peers

• Eramet: French mining and metallurgy group producing nickel (New Caledonia, Indonesia) and battery-grade nickel. A direct competitor in low-carbon battery-grade nickel for European EV OEMs.
• Boliden: Swedish mining and smelting company producing nickel, zinc, copper, and lead from European mines. Closely comparable to Terrafame as a European multi-metal miner with integrated downstream processing and a focus on sustainable production.
• Nyrstar: Global multi-metals business and Trafigura subsidiary that smelts zinc, lead, and copper. Highly relevant given the Trafigura connection to Terrafame's board and overlapping European zinc/copper intermediate supply activities.
• Umicore: Belgian materials technology company and a major European producer of cathode active materials and battery chemicals. Comparable as both a Terrafame customer (offtake) and a downstream peer in the EU battery materials value chain.
• Aurubis: European leader in copper smelting and recycling, also processing precious and specialty metals. Comparable as a European non-ferrous metals refiner serving similar industrial customer bases.

Regional players

• Outokumpu: Finnish-headquartered stainless steel manufacturer and former mining/metals conglomerate. Comparable as a Finnish metals industry player with historical ties to the region's mining sector, though now focused downstream on stainless steel rather than primary mining.
