Wolfspeed has received a conditional loan commitment of up to $1.5 billion from the U.S. Department of War, channeled through the department's Office of Strategic Capital (OSC), to fund domestic silicon carbide (SiC) materials and wide bandgap power device production with a direct national security mandate.

The commitment letter, announced by the company, carries a 30-year tenor — an unusually long duration that CEO Robert Feurle says reflects the strategic weight Washington places on wide bandgap semiconductors. "We believe the scale and 30-year tenor of this conditional commitment reflects the long-term importance of the technology and manufacturing capabilities Wolfspeed has built in the United States," Feurle said.

The financing is conditional, not disbursed. Wolfspeed must satisfy the terms of the commitment before funds flow, and the company describes the planned uses as including, "without limitation," a set of defined technology programs.

What will the money fund?

Wolfspeed plans a multi-year program built on its existing SiC technology, IP and manufacturing footprint in North Carolina, New York and Arkansas. The stated objectives are:

• Strengthen domestic SiC materials and power-device leadership
• Establish, expand or onshore low-voltage and/or high-voltage gallium nitride (GaN) power device production
• Advance GaN-on-SiC radio-frequency epitaxial wafer technology
• Develop domestic radiation-hardening capabilities for current SiC and future GaN products

Two workstreams stand out for their defense specificity. Wolfspeed intends to upgrade its GaN epitaxy capabilities for next-generation communications infrastructure and electronic warfare systems, and to develop radiation-hardening for its SiC and GaN product lines — capabilities aimed at space and other harsh-environment applications.

Why does the Pentagon want wide bandgap capacity?

"SiC and GaN have critical national security applications," Feurle said. "With this financing, the company would be well positioned to not only continue to serve the DoW but also expand our capabilities for the benefit of U.S. national security as a whole."

The company argues SiC and related semiconductor technologies are critical to next-generation power and RF applications across defense, aerospace, AI, critical infrastructure and other strategic commercial markets. That dual-use framing matters commercially: the loan supports defense-oriented programs such as rad-hard and RF epitaxy, but it also reinforces the materials base — SiC substrates and epiwafers — that underpins Wolfspeed's power-device business in electric vehicles, industrial power and energy infrastructure.

The deal also signals how the Department of War, through the OSC, is deploying loan authority to onshore semiconductor capabilities it considers strategically exposed. For Wolfspeed, which operates the only large-scale merchant SiC materials base across North Carolina, New York and Arkansas cited in the announcement, the commitment provides a long-dated funding runway at a moment when wide bandgap competition is intensifying globally.

Feurle framed the outcome in industrial-base terms: "This financing would strengthen our continued advancement of silicon carbide materials and wide bandgap power devices, reinforcing our efforts to build a more resilient U.S. semiconductor and defense industrial base."

If the conditions are met and the loan closes, Wolfspeed would hold dedicated federal financing for a 30-year program spanning SiC materials leadership, GaN power device onshoring, RF epitaxy and radiation hardening — a combination that could reshape the competitive dynamics of the U.S. wide bandgap supply chain.
