What changes

Restructuring agreement with top creditors on 22 June 2025, filing on 30 June.
Goal: cut total debt by about $4.6bn while continuing operations.

Wolfspeed refocuses on 200 mm wafers and exits 150 mm.

### Background On 30 June 2025, **Wolfspeed** (Durham, North Carolina), one of the world's main **silicon carbide (SiC)** producers, files for **Chapter 11** together with its Texas subsidiary. The filing follows a restructuring agreement reached on 22 June with its top creditors. ### Key facts - Goal: cut total debt by about **$4.6bn** and keep operating normally during the proceedings. - Key Japanese customer **Renesas**, bound by a ten-year supply deal ($2.06bn deposit), announces a loss of about ¥250bn ($1.7bn); its deposit is converted into convertible notes, shares and warrants. - Wolfspeed completes its exit from 150 mm operations to focus on **200 mm**, and cuts its leadership team by 30%. - The company was in talks with the CHIPS program office for federal funding. ### Why it matters Silicon carbide is at the heart of power electronics for electric vehicles, inverters and industrial drives. The filing of a major supplier shows the financial fragility of a very capital-intensive industry, and its immediate impact on customers such as Renesas that had secured volumes through prepayments. ### Takeaway Even a technology deemed strategic cannot escape the debt wall: Wolfspeed restructures rather than closes.
