The miss behind the doubling
Wolfspeed built its story on silicon carbide for artificial-intelligence data centres, and that line more than doubled from a year earlier. The quarter around it did not cooperate: revenue of 149.6 million dollars landed well below forecasts near 223.55 million dollars, and the adjusted loss of 2.26 dollars a share was far wider than the 0.52 dollars analysts had penciled in.[1]
The tape gave its verdict quickly. Wolfspeed shares fell about 7.5 per cent to 29.10 dollars during the session, then dropped a further 10.5 per cent after hours, trading near 26.03 dollars.[1]
What the price was weighing
A doubling AI line usually lifts a chip stock; here it did not, which points to what the market was actually weighing. Non-GAAP gross margin was still negative 19.9 per cent, better by only 70 basis points, and guidance keeps it negative. With a revenue run-rate a third short of expectations and cash still going out the door, the price read the burn, and the one growing segment was not big enough to change the arithmetic. The level is technical; the reason is the margin.[1]
What would change the read?
The test is in the next report. If first-quarter fiscal 2027 revenue reaches the upper end of the 140 million to 160 million dollar guidance and gross margin narrows toward breakeven, the case that this is a cash-burn problem rather than soft sentiment weakens. Until then, a growing AI line sitting on a negative margin is a story the tape can keep discounting.[1]
