A Strategic Pivot to AI Power

Wolfspeed (legacy CREE) reported fiscal Q4 2026 results on August 19, and the headline is clear: the company is betting its turnaround on AI data centers. CEO Robert Feurle emphasized, “In fiscal 2026, revenue in this business more than doubled versus fiscal 2025, including increasing approximately 20% from the fiscal third quarter to the fourth quarter.” — Robert Feurle · 2026-08-19 This growth is driven by the shift to 800-volt power architectures, new 800V DC deployments, and the company's Gen 5 MOSFET technology, which Feurle called a “substantial performance leap.” The company is also lining up design wins at leading power supply makers like LITEON and MacMic, serving hyperscaler customers. The opportunity extends beyond AC/DC power supplies to battery backup units, e-fuses, and high-voltage DC-to-DC conversion. Feurle noted in the Q&A, “One is, of course, the 800-volt deployment. That's a big milestone here, which is going to happen.” — Robert Feurle · 2026-08-19 This is a natural continuation of the company's earlier strategic pivot, as Robert had highlighted in the May call: “previous quarter, Q1 to Q2, we grew 50% on the data center side. This quarter, Q2 to Q3, we grew 30%.” — Robert Feurle, Chief Executive Officer · 2026-05-05 The momentum is unmistakable.

Financial Discipline and the Path to Breakeven

While the AI story is compelling, the financials remain challenging. Revenue for the quarter was $150 million, in line with guidance, but non-GAAP gross margin was still negative at -19.9%, though it improved 70 basis points sequentially. CFO Gregor Issum explained, “Fund utilization continues to be the primary driver of our gross margin profile and improving factory utilization remains one of the most important levers to drive margin expansion.” — Gregor Issum · 2026-08-19 The company is focusing on producing the same revenue with less capacity, which should eventually drive breakeven. Issum provided a concrete target:

on an $800 million annual run rate, that's probably the ballpark where a breakeven gross margin point lies right now.

The balance sheet has been strengthened with cash of $1.1 billion and net debt of $600 million, aided by conversions of 2L convertible notes. Operating cash flow was negative $54 million, but working capital improvements contributed $23 million. The company is also aggressively reducing debt, with a focus on refinancing the high-cost first-lien debt at ~16% interest.

Confluence with Market Themes

Wolfspeed's AI data center thrust aligns with a broader global theme. The 360-day tape shows AI data centers as a top advancer, with many semiconductor and power names participating. However, in the last 30 days, that same theme has flipped to the decliner list, suggesting a recent pullback in sentiment. Wolfspeed's positive momentum stands in contrast to this market wobble, potentially indicating that the company is ahead of the curve or that the sell-off is overdone. Additionally, silicon carbide market appears in the 360-day advancers, reflecting the structural growth of SiC across EV and industrial applications. Wolfspeed's focus on data center applications positions it to ride these secular tailwinds, even as it navigates the transition from 150mm to 200mm substrates. The company is shipping first engineering samples of 200mm substrates to multiple customers, a crucial step for long-term materials revenue. The recent earnings reporters list also includes WOLF (the correct ticker for Wolfspeed) with keywords like "data center applications" and "hyperscaler customers," reinforcing that the AI pivot is a company-wide, analyst-recognized theme. The market's near-term negative reaction to AI names may be a distraction, but Wolfspeed's execution in doubling AI revenue suggests real traction. In summary, Wolfspeed is executing a laser-focused strategy to leverage its silicon carbide technology for the AI power boom. While profitability is still a ways off, the company's rapid growth in the highest-margin data center segment and its disciplined capital management provide a credible path forward. The contrast between its AI revenue growth and the broader market's recent AI sell-off underscores that this is a company-specific story worth watching.
