MARCY, N.Y. — Wolfspeed, Inc. (NYSE: WOLF), which operates a silicon-carbide-wafer-fabrication facility in Marcy, has appointed Gregor van Issum as the company’s new chief financial officer effective Sept. 1, the Durham, North Carolina–based company announced.

The appointment comes a little over two weeks after Wolfspeed filed for Chapter 11 bankruptcy protection in a move to reduce its overall debt by $4.6 billion.

“We are excited to welcome Gregor to our team as Wolfspeed enters a new era,” CEO Robert Feurle said in the announcement. “I witnessed Gregor’s strong analytical and leadership skills firsthand during our time working together at ams-OSRAM. Gregor has helped lead large, multibillion euro businesses with complex manufacturing operations, which will be invaluable to Wolfspeed as we unlock the potential of our purpose-built 200mm platform. The board and I look forward to collaborating with Gregor as we position Wolfspeed for long-term growth and profitability.”

Van Issum succeeds interim CFO Kevin Speirits, who will remain with Wolfspeed to ensure a smooth transition. He brings more than 20 years of experience in transformational restructuring and strategic financial positions across the technology industry to Wolfspeed. Van Issum has held senior roles at semiconductor manufacturers ams-OSRAM AG and NXP Semiconductors N.V. Most recently, he served as executive VP, group controller at ams-OSRAM, where he also led the company’s cost-savings programs and sales initiatives in a dual role as the company’s chief transformation and performance officer.

“In this new role, my priority will be providing Wolfspeed’s investors with transparency and clarity, especially during this transformative period,” van Issum said. “Building on recent steps to restructure Wolfspeed’s balance sheet, I will draw on my experience navigating complex business cycles to help create a capital structure that offers agility to respond to rapid shifts in the market. My background in transformation and restructuring also positions me to support Wolfspeed’s strategic focus on improving profitability.”

Van Issum’s appointment follows the addition of David Emerson, who joined Wolfspeed in May in the newly created role of chief operating officer.

Wolfspeed has had a difficult 2025 so far with its stock price tumbling more than 77 percent year to date as of late afternoon trading on July 15.
