U.S. silicon carbide (SiC) semiconductor manufacturer Wolfspeed (WOLF) announced on the 7th that it has secured a conditional financing commitment of up to $1.5 billion (approximately NT$48 billion) with a 30-year term from the U.S. Department of Defense, aimed at strengthening domestic U.S. production capacity for wide-bandgap semiconductor materials and power devices. The announcement sent Wolfspeed’s after-hours stock price surging nearly 24%, reflecting the market’s positive interpretation of the unprofitable chipmaker securing long-term government funding.

According to a press release issued by Wolfspeed, the long-term financing will be specifically dedicated to supporting the development and production of silicon carbide materials and wide-bandgap power devices within the United States. These technologies are regarded as critical cornerstones of modern defense systems, with applications spanning unmanned aerial vehicles, high-efficiency engines, radar, and missile defense.

Beyond silicon carbide, Wolfspeed also plans to use the funds to upgrade gallium nitride (GaN) epitaxy technology to support next-generation communications infrastructure and electronic warfare systems. The company will simultaneously enhance the radiation-hardening capabilities of its existing silicon carbide products and future gallium nitride products, further expanding its technological depth in the defense and aerospace sectors.

Wolfspeed CEO Robert Feurle stated that silicon carbide and gallium nitride have critical applications for national security, and this financing not only enables the company to continue serving the U.S. Department of Defense but also allows it to expand related technological capabilities. He emphasized that the $1.5 billion scale and 30-year term reflect the long-term importance of the technology and manufacturing capabilities Wolfspeed has established in the United States.

CFO Gregor van Issum described the transaction as “another important milestone in the ongoing optimization of Wolfspeed’s capital structure and strengthening of its financial foundation.”

Warrant Terms and Transaction Conditions

This financing is not a simple loan but rather a hybrid arrangement with an equity participation mechanism. Under the loan terms, Wolfspeed will issue warrants to the U.S. Department of Defense based on volume-weighted average price (VWAP) proportionally at each funding tranche disbursement, collectively allowing the Department of Defense to acquire up to 7.5% of the company’s fully diluted equity.

Notably, this financing commitment is not yet finalized. Wolfspeed explicitly stated in its announcement that the transaction remains subject to financial, legal, and technical due diligence, as well as completion of definitive agreements, government approvals, congressional appropriations, and third-party consents. The company also cautioned investors that there can be no assurance that any funds will ultimately be disbursed.

Part of the U.S. Domestic Supply Chain Strategy

The U.S. Department of Defense has been steadily committing resources in recent years to enhance domestic U.S. production capacity and self-sufficiency in critical materials. Last July, the Department of Defense provided capital, a price floor guarantee, and a guaranteed customer for rare earth materials to rare earth supplier MP Materials (MP), signaling that Washington’s strategic positioning in critical minerals and advanced materials is progressively expanding.

Silicon carbide substrates, compared with traditional silicon materials, are particularly well-suited for high-voltage applications, including data centers, electric vehicles, and satellite technology. While the majority of semiconductors still use silicon as their primary material, silicon carbide’s penetration in the power device segment is rapidly increasing. Gallium nitride is widely used in high-end electronic equipment such as radar, and both materials are regarded as core to U.S. defense modernization.

Wolfspeed currently operates manufacturing facilities in North Carolina, New York, and Arkansas. The company plans to leverage these existing facilities to consolidate domestic U.S. silicon carbide material and power device production capacity, while establishing and expanding domestic production capabilities for low-voltage and high-voltage gallium nitride power devices, and advancing GaN-on-SiC RF epitaxial wafer technology.

Stock Performance and Market Reaction

Wolfspeed closed at $31.37 in regular trading on the 7th, down 1.45%. Following the announcement, the after-hours stock price surged as much as 24% to $38.80 per share, and remained up more than 21% at $37.16 as of press time.

Over the past year, Wolfspeed’s stock has risen approximately 18% cumulatively, but remains down more than 50% from its 52-week high of over $80 set in May. The company’s market capitalization stands at approximately $2 billion (about NT$64 billion), making it a relatively small enterprise in the capital markets.

Market attention on the company is relatively limited, with only three analysts currently covering Wolfspeed stock, and all three rate the shares as “Hold.”

For Wolfspeed, the significance of this financing commitment extends beyond the capital itself. The company is currently unprofitable and continues to invest heavily in its North Carolina and New York facilities. However, as related construction nears completion, the company’s capital expenditures in 2026 are gradually declining. This long-term, low-cost government financing could provide additional financial cushioning during a critical operational inflection period.

From a broader perspective, the U.S. government’s approach of providing long-term financing directly to private semiconductor manufacturers through the Department of Defense, while sharing in potential equity upside through warrants—a model of “government funding, corporate capacity expansion, and national strategic material security”—is increasingly becoming an important policy tool for Washington to strengthen critical supply chain resilience.
