e-VAC Magnetics
Bottleneck owner
US rare-earth NdFeB permanent-magnet maker (VAC Group) reshoring magnet supply for defense, EV and robotics.
eVAC Magnetics produces neodymium-iron-boron (NdFeB) permanent magnets - the high-energy-density magnets essential to electric motors, actuators, guidance systems and robotics. Through its Sumter, South Carolina facility (opened fall 2025), eVAC is reshoring rare-earth magnet production to the US, using VACODYM(R) alloy grades and grain-boundary-diffusion processing, and claims up to 10x the energy density of ferrites. It targets mission-critical military applications (electric propulsion, actuators, guidance, undulators) and civilian uses (EV/robotics motors, consumer electronics, medical equipment). Parent Vacuumschmelze (VAC) brings roughly a century of magnet know-how; eVAC shipped the first US-made commercial rare-earth magnets of the 21st century in December 2025.

Evidence boundary
Original analysis and independent corroboration remain under development. Commercial scale and durable technical advantage remain under review.
What makes it defensible
One of the western world's only at-scale NdFeB permanent-magnet producers - a hard-to-replicate rare-earth magnet supply chain for defense, EV and robotics motors.
Position in the stack: Critical-materials component supplier: manufactures the rare-earth magnets that motors, actuators and defense systems depend on, onshoring a China-dominated step.
Who buys it
Named customers: General Motors, U.S. Department of Defense
Founding team
Erik Eschen — Chief Executive Officer, VAC Group — CEO of VAC Group, the German parent of eVAC Magnetics; leads the group's US NdFeB magnet build-out in Sumter, South Carolina.

Energy Fuels amends proposed ~$1.9B VAC acquisition
What this source supports: Energy Fuels 8-K (filed 2026-10-13): First Amendment to the ~$1.9B cash-and-equity acquisition of VAC Group B.V. - which owns eVAC Magnetics - addressing a customer commercial supply agreement, repayment of certain indebtedness and potential purchase-price adjustments, after a customer purported to terminate the Sumter supply agreement (arbitration entered July 2026). VAC H1-2026 revenue EUR 211.489M (+34.8%); Sumter capacity 2,000 tpa scalable to 12,000 tpa.
What it does not establish: Filed by the acquirer, not eVAC; the customer is unnamed and the contract value at issue is not quantified. Structure allows price adjustment rather than terminating the deal.
