The Department of War's Office of Strategic Capital (OSC) issued Wolfspeed a conditional commitment on October 7 for a loan of up to $1.5 billion to expand U.S. silicon carbide (SiC) and gallium nitride (GaN) production. No money has moved. Funding depends on diligence, definitive agreements and approvals.
"The contemplated investment advances U.S. military and economic security by helping build a secure, reliable domestic supply chain for SiC and GaN that benefits the Department of War, the U.S. defense industrial base, and the broader U.S. economy," said David A. Lorch, Director of the Office of Strategic Capital.
What's happening
- The letter contemplates a senior secured delayed-draw term loan of up to $1.5 billion with an expected 30-year maturity and a 36-month draw period.
- A $600 million initial tranche would refinance Wolfspeed's first lien senior secured notes due 2030; up to $900 million more would follow in tranches of $200 million to $400 million.
- Later tranches would fund U.S. SiC wafer and device buildout, GaN power device production, GaN-on-SiC radio frequency epitaxy and radiation-hardening capabilities.
- Wolfspeed would issue the Department of War warrants for up to 7.5% of its fully diluted equity, issued pro rata as tranches fund.
Why it matters
- Wolfspeed makes SiC wafers, SiC power devices and GaN-on-SiC wafers, materials the Department of War ties to radars, electronic warfare, directed energy weapons and missile defense systems.
- The company plans to upgrade GaN epitaxy for communications infrastructure and electronic warfare systems, and to radiation-harden its SiC and future GaN products.
- If the deal closes, the Department of War becomes senior secured lender to a company that exited Chapter 11 in September 2025 after cutting total debt by about 70%.
Financial impact
- Balance sheet: at closing, the initial tranche would retire the 2030 first lien notes, replacing market debt with a 30-year government loan; closing timing not disclosed.
- Income statement: interest would be a comparable-maturity Treasury rate plus a provisional 1.25% to 1.75% premium, capitalizable for five years, then amortizing over a 25-year schedule.
- Share count: the warrants, split 5% and 2.5% at VWAP-based prices with 10-year terms, dilute holders only as tranches fund; timing not disclosed.
- Cash: Wolfspeed must raise a $750 million Minimum Contribution from sources received after June 28, 2026, including $50 million of third-party equity before the facility takes effect.
The intrigue
- The first $600 million refinances existing debt rather than building capacity, so new GaN and radiation-hardening work depends on later tranches with their own conditions.
- Commerce signed a non-binding preliminary memorandum of terms for up to $750 million in CHIPS Act funding in October 2024; neither of the October 7 announcements mentions that award.
- Shares closed down 1.5% at $31.37 on Wednesday, then rose 25% to $39.20 after hours, MarketWatch reported.
The fine print
- Definitive agreements require congressional authorizations, appropriations, OMB concurrence, OSC diligence, lender waivers, offtake commitments and efforts to equitize most of Wolfspeed's convertible notes.
- Each later tranche needs further diligence, offtake agreements and pro forma compliance with a loan-to-value covenant, so the $900 million is not assured after closing.
- Definitive agreements would add change-of-control limits, a U.S.-citizen board majority and a U.S. headquarters requirement through the later of repayment or maturity, plus a non-voting OSC board observer.
