General Motors Ends VAC Rare-Earth Magnet Long-Term Supply Deal as Arbitration Begins
General Motors (GM) terminated a long-term supply deal with VAC for EV magnets, leading to arbitration. VAC's U.S. unit seeks damages, claiming wrongful termination. The 2023 agreement was for a $500M South Carolina plant, with 90% output for GM. Energy Fuels, acquiring VAC, notes the dispute may affect the $1.9B deal. GM has scaled back EV sales amid reduced incentives.
