E-VAC Magnetics initiated arbitration proceedings on July 7, 2026, to challenge the termination of a commercial supply agreement with one of its customers, according to an Energy Fuels filing with the U.S. Securities and Exchange Commission. The customer, which was not named in the filing, had submitted formal notice terminating the agreement on July 1, 2026. The contractual dispute began in April 2026, before progressing to a termination notice and then arbitration. E-VAC is seeking a ruling that the customer's termination breached the agreement's terms, placing the validity of the termination at the heart of the proceedings it initiated. The filing described the company's request as seeking "a declaration that the termination was contrary to the terms of the agreement."

E-VAC's operations include a magnet production facility in Sumter, South Carolina, with a nominal production capacity of about 2,000 metric tons annually, according to the company. The facility opened in the fall of 2025, according to E-VAC's announced timeline for its U.S. operations. The company said it was ramping up the facility to full capacity during 2026. General Motors had announced a binding long-term agreement with Vacuumschmelze, known as VAC, to produce magnets in North America, according to the automaker's investor relations website. The original plan for the plant called for supporting General Motors' requirements for at least 10 years, according to an announcement by Ara Partners. The announced plan thus combined the establishment of magnet production capacity in North America with a multiyear supply arrangement to meet the U.S. company's needs.

General Motors also has a separate supply agreement with Noveon Magnetics for rare earth magnets, according to a Noveon announcement. The agreement covers magnets for General Motors' full-size sport utility vehicles and large trucks. Noveon's deliveries under the agreement began in July 2025, adding another supply channel to the automaker's arrangements for obtaining these magnets. In the context of its electric vehicle investments, General Motors announced in January 2026 that it would take $6 billion in charges, Reuters reported. The company said the charges were related to scaling back some electric vehicle investments, while the announced Noveon agreement covers magnet supplies for the vehicle and truck categories specified in it.

The contractual proceedings come against the backdrop of an acquisition announced by Energy Fuels, which entered into a definitive agreement to buy VAC. The company put the transaction's announced equity value at $1.9 billion, according to the acquisition announcement. Energy Fuels' original announcement set an expected closing date of early 2027. Completion of the acquisition is subject to closing conditions and required regulatory approvals, according to the announcement. As for the dispute under arbitration, the regulatory filing described its ultimate outcome as "still uncertain."
