Wolfspeed's New Board Director: A Signal of Disciplined Execution

DURHAM, NC – July 29, 2026 – Wolfspeed, Inc. (NYSE: WOLF), the global leader in silicon carbide technology, has appointed veteran technology executive Andy W. Mattes to its Board of Directors. While board appointments are routine corporate news, this move is a clear signal of intent from a company navigating a critical juncture. Coming just over a year after a new CEO took the helm and weeks after emerging from a major financial restructuring, bringing in a seasoned operational heavyweight like Mattes speaks volumes about Wolfspeed’s new priorities: disciplined execution, accelerated profitability, and solidifying its leadership in a fiercely competitive market.

A Proven Leader for a Pivotal Moment

In a statement, Wolfspeed CEO Robert Feurle, who took the chief executive role in May 2025, called Mattes a "distinguished global technology leader whose experience and strategic perspective will be a tremendous asset." He added that Mattes' expertise will be "invaluable during this transformative period." This "transformative period" is no understatement. The company has recently undergone a pre-packaged Chapter 11 restructuring, a strategic maneuver completed in June 2025 to slash its debt by approximately 70% and reduce annual cash interest payments by over $200 million. While this move fortified the balance sheet, it came at the cost of significant equity dilution for previous shareholders.

It is within this post-restructuring context that Mattes' appointment becomes particularly significant. His mandate, and that of the leadership team, is to translate the company's technological supremacy in silicon carbide into consistent financial performance. The core challenge for Wolfspeed lies in ramping up its highly capital-intensive 200mm wafer fabrication facilities, achieving stable production yields, and turning its market-leading position into positive free cash flow. Mattes, who will also chair the board's Compensation Committee, brings a reputation for precisely this kind of operational rigor. His experience is seen as crucial to guiding the company as it executes its strategic priorities and capitalizes on what Feurle calls "compelling long-term opportunities."

Mattes himself acknowledged the critical timing, stating, "I am excited to join Wolfspeed at this pivotal time in its evolution." He pointed to the foundational steps taken by Feurle's team over the past year to position the company for progress, signaling his alignment with the new focus on operational and financial discipline.

A Track Record of High-Stakes Transformation

To understand the strategic calculation behind Mattes’ appointment, one need only look at his four-decade career, which is a case study in managing complex technology businesses through periods of intense change. His most recent CEO role at Coherent, a leader in laser technology, is a prime example. Taking the helm in April 2020, he navigated the company through the global pandemic, nearly tripling operating margins and revenue in just two years. His leadership not only transformed the company’s operational posture but also culminated in its strategic $6.6 billion acquisition by II-VI Incorporated, a deal for which his efforts laid the critical groundwork.

Prior to Coherent, Mattes led Diebold Nixdorf from 2013 to 2017, where he orchestrated another significant transformation. He refocused the company on services and software, a move that helped transform it into the world's largest ATM provider. His tenure was defined by the complex, $1.8 billion cross-border acquisition and integration of Germany's Wincor-Nixdorf, a testament to his expertise in executing large-scale mergers. His earlier career, forged over two decades at Siemens and later in senior roles at Hewlett Packard—where he notably spearheaded the post-merger integration of EDS—further cemented his reputation as a leader capable of driving organic growth and managing complex global operations. This deep history in turning around and scaling technology hardware, software, and service businesses is precisely the skillset Wolfspeed requires as it scales its own operations.

Fortifying Governance for a New Era

Beyond his operational prowess, Mattes brings a wealth of governance experience that will be vital for Wolfspeed as it seeks to rebuild investor confidence. With over two decades of public-company board experience spanning three continents, his perspective is both global and diverse. He currently serves on the boards of European technology firms AT&S AG and ams OSRAM AG, as well as the semiconductor test and handling equipment supplier Cohu, Inc.

This multi-faceted board experience provides a broad view of the semiconductor ecosystem and its adjacent industries. It offers Wolfspeed’s board a rich source of insight into best practices for governance, strategy, and risk management, which is particularly valuable for a company that has recently navigated the complexities of a Chapter 11 filing. His appointment reinforces the board's oversight capabilities and signals a commitment to strong, independent governance as the company pursues its long-term strategy. For a company whose stock performance has been weighed down by concerns over cash burn and profitability, adding a director with a proven record of creating shareholder value is a powerful statement.

The High-Stakes World of Silicon Carbide

Mattes joins Wolfspeed at a time when the stakes in the silicon carbide (SiC) market have never been higher. SiC is a foundational technology for the global transition to electrification, offering superior efficiency for power electronics in electric vehicles (EVs), renewable energy systems, AI data centers, and advanced industrial applications. The market is projected to soar to $17 billion by 2029, and the race to capture share is intense.

Wolfspeed is a pioneer and a leader, holding a significant share of the global EV semiconductor supply chain and pushing the technological envelope with innovations like its 200mm SiC wafers. However, it faces formidable competition from semiconductor giants like STMicroelectronics, Infineon, and Onsemi, all of which are investing billions to expand their own SiC capacity. In this environment, technological leadership alone is not enough. The ability to manufacture at scale, control costs, and deliver reliably is paramount. The appointment of Andy Mattes is a clear acknowledgment of this reality, adding a battle-tested operational strategist to the board to help ensure Wolfspeed not only leads in innovation but also wins in execution.
