He also led Ams Osram’s cost savings programs and sales initiatives in his dual role as the company’s chief transformation and performance pfficer.
Van Issum commented: “In this new role, my priority will be providing Wolfspeed’s investors with transparency and clarity, especially during this transformative period,” said Van Issum. “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."
He added: "My background in transformation and restructuring also positions me to support Wolfspeed’s strategic focus on improving profitability. At this pivotal time in the company’s life cycle, I am honoured to help guide Wolfspeed as it leverages its competitive advantages—world-class facilities, exceptional talent, and robust intellectual property—to advance the incredible progress that Robert and the Wolfspeed team have made in recent months and solidify its leadership in SiC technology.”
Van Issum’s appointment follows the addition of David Emerson, who joined Wolfspeed in May in the newly created role of COO.
