Why is Wolfspeed stock tumbling today?

Wolfspeed stock suffered a significant 10.5% drop in pre-market trading on Thursday, plummeting to $26.03 from its prior close of $31.50. The dramatic decline follows the company's release of its fourth-quarter 2026 earnings report on Wednesday, which fell well short of expectations. Wolfspeed reported an adjusted loss of $2.26 per share, a stark contrast to analyst consensus estimates of a mere $0.52 loss.

Moreover, quarterly revenue of $149.6 million represented a substantial 33% shortfall of the $223.55 million anticipated by analysts. The disappointing results were exacerbated by TD Cowen's decision to maintain a "Hold" rating on the stock, indicating limited near-term growth potential despite a cautiously optimistic forward guidance projection of $140 million to $160 million in revenue for the first quarter of fiscal 2027.

Wolfspeed's partnership with LITEON on an AI data center project, while strategically relevant, failed to alleviate investor worries about the company's persistent losses and deteriorating gross margins. With the broader U.S. market displaying little support, as evidenced by the S&P 500's flat performance, Dow Jones slight decline, and Nasdaq's minimal gain, the decline in Wolfspeed stock appears to be driven entirely by company-specific factors rather than any macroeconomic or sector-wide shifts.

The stock's current valuation significantly lags its 52-week range, trading well below the $1.16 to $80.82 price band.
