  • The regular-session decline came amid a broader semiconductor sector selloff tied to rising Treasury yields and AI valuation concerns.
  • Fiscal fourth-quarter Revenue came in at $149.6 million, down from $197 million a year earlier, though the adjusted loss of $2.26 per share beat consensus estimates for a $2.45 loss.

Shares Fall During the Session, Then Extend Losses After Hours

Wolfspeed shares closed down about 7.50 percent at $29.10 during the regular session amid a broader semiconductor sector selloff tied to rising Treasury yields and AI valuation concerns, then declined a further 7.75 percent in after-hours trading to $26.85 following the release of fiscal fourth-quarter results. Revenue came in at $149.6 million, down from $197 million a year earlier, though the adjusted loss of $2.26 per share beat consensus estimates for a $2.45 loss.

Wolfspeed (NYSE:WOLF) is a Durham, North Carolina based innovator in wide bandgap semiconductor technology, specializing in silicon carbide and gallium nitride materials and devices for electric vehicle, 5G, renewable energy, and AI data center applications, operating a vertically integrated Business model from raw crystal growth through finished power devices.

Soft Guidance Overshadows AI Demand Commentary

Investors appear focused on continued top-line contraction, negative gross margins, and soft fiscal first-quarter guidance of $140 million to $160 million in revenue, overshadowing management's commentary that AI data center demand more than doubled sequentially and progress on the company's fifth-generation silicon carbide MOSFET launch. The company's ongoing ramp at its Mohawk Valley fabrication Facility continues to weigh on gross margins even as unit demand for its underlying technology grows.

Sector Momentum and Volatility Heading Into the Print

The results followed a period of elevated stock volatility, with shares having fallen roughly 10 percent the prior day and analyst price targets recently trimmed. Power semiconductor peers have rallied recently on reports of a faster ramp in next-generation AI chip demand from major hyperscale customers, a dynamic that could eventually benefit Wolfspeed's silicon carbide exposure if the company can resolve its near-term profitability challenges.

What Comes Next

Wolfspeed shares closed down about 7.50 percent at $29.10 and fell further after hours following fiscal fourth-quarter results that showed continued revenue contraction and soft guidance. These are the verified facts as reported. Whether the stock stabilizes may depend on progress ramping the Mohawk Valley fab and whether AI-related demand growth can offset broader end-market softness.
