The other information reported in the Original Filing is not otherwise modified by this Amendment No. 1.
Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
Election of Andreas W. Mattes as Director
On July 28, 2026, the Board of Directors (the “Board”) of Wolfspeed, Inc. (the “Company”) appointed Andreas (“Andy”) W. Mattes as a member of the Board and as a member of the Compensation Committee of the Board, with such appointments effective immediately.
Mr. Mattes, age 65, served as the President and Chief Executive Officer of Coherent, Inc. (Nasdaq: COHR), a leading provider of laser and laser-based technologies for scientific, commercial, and industrial applications, from April 2020 to July 2022. Prior to Coherent, from July 2019 to April 2020, Mr. Mattes served as a Senior Advisor at McKinsey & Company, where he focused on advising international businesses on high-impact transformations, agile change, and positioning companies for growth. He has held senior leadership roles at Diebold Nixdorf, Hewlett Packard and Siemens. Mr. Mattes currently serves as a member of the Supervisory Board of ams-OSRAM AG and as Chairman of the Supervisory Board of AT&S AG (Austria Technologie & Systemtechnik), and serves on the board of directors of Cohu, Inc. (Nasdaq: COHU).
Mr. Mattes will receive an annual cash retainer of $80,000 for service as a member of the Board and an additional annual cash retainer of $10,000 for service on the Compensation Committee of the Board. In addition, Mr. Mattes is eligible to participate in the 2025 Management Incentive Compensation Plan. Mr. Mattes will receive an initial equity award of restricted stock units (“RSUs”) with a grant date fair value equal to $500,000, which will vest as to one-third of the RSUs on the first anniversary of the date of grant and as to the remaining RSUs in equal quarterly installments over the following two years. Mr. Mattes will also be eligible for an annual equity award of RSUs with a grant date fair value equal to $200,000, which will vest in full on the first anniversary of the date of grant.
In connection with his election, Mr. Mattes will enter into the Company’s standard indemnification agreement for directors and officers, a copy of which is filed as Exhibit 10.6 to the Company’s Form 10-Q filed with the Securities and Exchange Commission (the “SEC”) on November 7, 2025, and is incorporated herein by reference.
There are no arrangements or understandings pursuant to which Mr. Mattes was elected as a director. Mr. Mattes is not a party to any transaction that would require disclosure under Item 404(a) of Regulation S-K promulgated under the Securities Act of 1933, as amended. The Board determined that Mr. Mattes satisfies the New York Stock Exchange definition of “independent director.”
A copy of the Company’s press release announcing the appointment of Mr. Mattes was previously attached to the Original Filing as Exhibit 99.1 and is incorporated herein by reference.
