Why is Wolfspeed stock tumbling today?
Wolfspeed (WOLF) shares fell 10.5% to $26.03 in pre-market trading after reporting fiscal Q4 2026 earnings. The company posted an adjusted loss of $2.26 per share, missing estimates by $1.74, and revenue of $149.6M, down 24% YoY and below expectations. TD Cowen maintained a Hold rating.
