- The $500 million South Carolina plant was to supply magnets for GM's electric vehicles.
- Parties have not issued public statements, citing arbitration confidentiality.
Overview
General Motors (GM) canceled a long-term supply agreement for permanent magnets with Germany's VAC at VAC's new South Carolina plant.
VAC's U.S. unit, e-VAC Magnetics, claims wrongful termination and has filed for arbitration seeking damages.
The supply contract was intended to last at least 10 years, with the plant supplying GM's electric vehicles.
The arbitration has attracted attention due to its implications for U.S. rare-earth supply chains and EV production.
What Happened
General Motors canceled a long-term permanent magnet supply agreement with Germany's VAC, intended to support US-based EV production from a new South Carolina plant.
VAC's U.S. unit, e-VAC Magnetics, contends the termination was wrongful, and subsequently filed for arbitration seeking damages over the canceled agreement.
The plant, costing $500 million and commissioned in late 2025, was to supply GM's EV models for at least 10 years, allocating 90% of output to GM.
The dispute became public through regulatory filings and is not accompanied by any press release from the companies; the parties cite confidentiality and have declined to comment further.
Context
VAC and General Motors signed the supply agreement in 2023 as part of a broader effort to secure domestic sources of rare-earth magnets, historically dominated by Chinese producers.
Since 2025, the U.S. EV market environment shifted after changes in federal incentives, with General Motors scaling back some electric vehicle investments.
Energy Fuels agreed to acquire VAC for $1.9 billion in June, aware of the pending dispute and indicating the purchase price could be adjusted based on arbitration results.
Why It Matters
- The arbitration concerns a major supply agreement for critical rare-earth magnets, essential for EV production in the U.S.
- It highlights challenges in building secure, non-Chinese controlled rare-earth supply chains amid shifting U.S. EV market incentives.
- The outcome could affect future commercial arrangements and investment in U.S.-based advanced manufacturing.
