Strategic Initiatives
Growth programs, investments, and their expected impact
A $120 million capital investment program to debottleneck production facilities in France and the United States, specifically aimed at increasing the output of 4N+ high-purity silicon.
Securing long-term, low-carbon power purchase agreements in Europe, highlighted by a competitive new 10-year French energy agreement.
Expected impact: Reduces energy cost volatility, provides predictable pricing, and increases operational flexibility by enabling 12-month production schedules in France.
Active evaluation of a potential restart of cost-competitive Venezuelan operations, which include three ferrosilicon furnaces (90,000-ton capacity) and one manganese alloy furnace (30,000-ton capacity).
Expected impact: Provides over 100,000 tons of incremental capacity with the flexibility to convert furnaces to silicon metal or produce critical materials, leveraging proximity to the U.S. market.
Mergers, Acquisitions & Partnerships
Recent deals and strategic collaborations
Recent Acquisitions
Acquisition of a high-purity quartz mine in the United States to secure a stable, domestic, and vertically integrated supply of high-quality raw materials for silicon metal production.
Financial impact: Ensures long-term cost-competitiveness and supply chain traceability from quartz to high-purity silicon.
Strategic Partnerships
Collaborating to develop the first battery-ready metallurgical silicon for low-cost, high-range EV batteries. Ferroglobe increased its investment to $17 million for an approximate 10% stake. Coreshell's proprietary nanomaterial electrode coating prevents the degradation of micrometric silicon, unlocking its potential to replace graphite in lithium-ion battery anodes.
Terms: $17 million total investment for an approximate 10% equity stake
A three-year agreement effective January 1, 2024, where Ferroglobe supplies high-quality quartzite and metallurgical grade silicon (MGS) to LONGi, supporting LONGi's strategy to increase purchases from leading Western suppliers and reinforcing Ferroglobe's position in the solar PV supply chain.
Terms: Three-year supply agreement; specific pricing terms are confidential
