High-impact appointment underscores Wolfspeed’s ability to attract world-class talent and advance its leadership in the next generation of silicon carbide devices

DURHAM, N.C.--(BUSINESS WIRE)-- Wolfspeed, Inc. (NYSE: WOLF), the global leader in silicon carbide technology, today announced the appointment of Matthias Buchner as Senior Vice President of Global Sales and Chief Marketing Officer, effective December 1, 2025. Buchner will report directly to Chief Executive Officer Robert Feurle.

In this new role, Buchner will lead Wolfspeed’s global sales and marketing organizations with a focus on leveraging the Company’s next-generation silicon carbide (SiC) devices, produced on its vertically integrated 200 mm manufacturing platform. His appointment comes at a critical juncture, as Wolfspeed sharpens its focus on product innovation and device production — reflecting the Company’s leadership in scaling silicon carbide manufacturing to meet global demand. The appointment also supports Wolfspeed’s strategy to broaden its customer base across diverse, high-growth markets including automotive, renewable energy, industrial power systems, and AI-driven data infrastructure.

Buchner joins Wolfspeed from Infineon Technologies AG, where he most recently served as Senior Vice President of Marketing for the Power & Sensor Systems Division, responsible for strategic communication, partnership management, distribution marketing, digital marketing and marketing operations for a $3+ billion business. Over his more than 20-year career, he has held senior leadership positions at Infineon, Micron Technology, and other technology companies, with deep experience in both silicon and silicon carbide power solutions, business development, and global customer engagement.

“Attracting a world-class sales and marketing executive like Matthias at this critical juncture underscores Wolfspeed’s commitment to capturing the immense opportunities ahead,” said Robert Feurle, Wolfspeed’s President and Chief Executive Officer. “His global leadership experience across silicon and silicon carbide technologies — spanning automotive, industrial, and other competitive markets — will be instrumental as we strengthen our customer relationships and expand into rapidly growing segments such as AI data centers, renewable energy, grid infrastructure, and aerospace and defense. With Matthias joining our team, Wolfspeed is exceptionally well positioned to translate our vertically integrated silicon carbide platform into sustainable, profitable growth.”

Buchner’s appointment further strengthens Wolfspeed’s leadership team as the Company continues to focus on improving operational execution, scaling manufacturing capacity, and expanding its position as the global leader in silicon carbide technology.

“I am very excited to join Wolfspeed at this important moment for the company and the industry,” said Matthias Buchner. “Wolfspeed’s deep domain expertise in producing silicon carbide devices sets the industry standard for performance and quality in today’s competitive landscape. Building strong, trusting relationships with our customers will be a key focus for me immediately out of the gate, as we work together to accelerate the global transition from silicon-based to silicon-carbide-based technologies.”

Recent Strategic and Operational Progress

Wolfspeed recently completed a strategic refinancing initiative that has strengthened the Company’s balance sheet and positioned it for sustained, profitable growth. In conjunction with this effort, Wolfspeed has rationalized its global production footprint to align with demand and enhance capital efficiency. This includes the planned closure of its 150mm device fabrication facility on the Durham campus by the end of calendar 2025, as well as the decision to discontinue development of a proposed device fabrication facility in Saarland, Germany. These actions streamline Wolfspeed’s manufacturing operations around its next-generation 200mm silicon carbide platform and support the Company’s long-term focus on operational excellence, productivity, and profitability.

Wolfspeed has invested in state-of-the-art, next-generation facilities in the United States, including its advanced materials factory in North Carolina, device fabrication operations in New York, and device packaging facility in Arkansas. Together, these sites provide ample capacity and flexibility to serve customer needs efficiently and reliably from a consolidated U.S. footprint.
