Analysis
Wolfspeed generated $149.6 million of fourth-quarter revenue, which the company described as aligned with the midpoint of its guidance range. Power Products contributed $106.3 million and Materials Products contributed $43.3 million. The company highlighted AI data center revenue as its fastest-growing end market, stating that it more than doubled year-over-year in fiscal 2026 and increased approximately 20% sequentially in the fourth quarter. Product and commercial actions included the launch of the fifth-generation SiC MOSFET, a dedicated Silicon Valley data center solutions team, a strategic collaboration with LITEON Technology, and a Memorandum of Understanding with GE Aerospace.
Profitability remained under pressure. GAAP gross loss was ($36.8) million, producing a (25)% GAAP gross margin, while non-GAAP gross loss was ($29.8) million and non-GAAP gross margin was (20)%. GAAP operating loss was ($115.4) million, non-GAAP operating loss was ($92.1) million, and adjusted EBITDA was ($62.4) million. Fourth-quarter restructuring and other expenses were $15.9 million, and the filing also states that the company implemented additional headcount reductions in the second and fourth quarters of fiscal 2026.
Cash generation remained negative in the quarter, with net cash used in operating activities of ($54.1) million and free cash flow of ($60.9) million. At June 28, 2026, the company reported $1,088.6 million of cash, cash equivalents, and short-term investments, alongside $931.0 million of long-term debt and $756.5 million of convertible notes, net. Management emphasized debt reduction and lowering the cost of capital, while noting that holders of $46 million of convertible notes voluntarily converted debt to equity during the fourth quarter.
For the first quarter of fiscal 2027, Wolfspeed expects revenue of $140 million to $160 million, non-GAAP gross margin to remain negative, and non-GAAP operating expenses of $62 million to $66 million. The immediate operating focus is therefore on maintaining demand momentum in AI data center applications while improving a gross-margin profile that remains below zero. Comparisons with the predecessor-year period require caution because the company states that its Successor financial statements after September 29, 2025 are not comparable with Predecessor financial statements on or before that date due to fresh-start accounting after its Chapter 11 emergence.
