AI Data Center Qualification Wolfspeed's silicon carbide chips qualified for LITEON's AI data center power systems, a key win that initially boosted investor optimism about demand from AI infrastructure.
This was a new positive development that drove early-quarter momentum.
Patent Lawsuit Against Navitas Wolfspeed sued Navitas for patent infringement, signaling defense of its technology and potentially limiting competition in the silicon carbide market.
This legal action was a new event that could protect Wolfspeed's market position.
Aerospace MoU with GE Wolfspeed signed a memorandum of understanding with GE for aerospace applications, opening a new potential market for its power electronics.
This partnership represented a new growth avenue beyond AI data centers.
Q4 Earnings Miss and Stalled Growth Q4 earnings badly missed expectations with a $2.26 per-share loss, revenue down 24% year-over-year, and negative gross margins; flat guidance signaled that AI-driven growth had stalled, causing shares to plunge over 10%.
This was the major negative event that erased earlier gains and left the stock under pressure.

AI data center demand signal lifts power semis Mizuho flagged a faster ramp of NVIDIA's Vera Rubin AI systems, with power content per rack jumping from $15,000 to $115,000. Wolfspeed rose 5.7% as investors bet on more chip demand. This shows the AI growth story that has driven the stock is still alive.
It explains the positive force behind WOLF's move this period: AI data center demand expectations.
Q4 earnings miss shatters growth narrative Wolfspeed reported a quarterly loss of $2.26 per share, far worse than the $0.52 expected, on revenue of $149.6 million that missed estimates. Revenue fell 24% from a year ago and gross margin turned negative. The stock plunged over 10% as the AI-driven growth that doubled last year appears to have stalled.
It is the single biggest new event this period and directly explains the sharp drop in WOLF's price.
Weak guidance signals no near-term recovery Management guided to about $150 million in revenue for the current quarter, essentially flat with the just-reported quarter. That tells investors the AI data center growth that more than doubled in fiscal 2026 has stalled, removing the main reason many held the stock. Without a clear rebound, the stock faces continued pressure.
It shows the forward-looking problem that keeps WOLF's price down beyond the one-time earnings miss.

LITEON AI data center partnership Wolfspeed's silicon carbide chips qualified for LITEON's power systems used in hyperscale AI data centers. This locks in a major customer and opens the door to more cloud providers, boosting future sales and supporting the stock.
This is the newest and most concrete demand win, directly tying Wolfspeed to the fast-growing AI data center market.
Patent lawsuit against Navitas Wolfspeed sued rival Navitas for patent infringement on power chips. If Wolfspeed wins, it could weaken a competitor and protect its pricing power, which investors see as a positive for the stock.
This is a new legal action that could shift competitive dynamics in Wolfspeed's favor.
Humanoid robot demand lifts power electronics Power electronics stocks, including Wolfspeed, jumped 9% as investors bet on growing demand from humanoid robots. Wolfspeed's chips are used in motors and power systems, so more robot production means more potential sales.
This highlights a new demand driver from robotics that directly lifted Wolfspeed's shares.
GE Aerospace MoU for SiC power modules Wolfspeed signed a memo with GE Aerospace to develop high-voltage silicon carbide power modules for future aerospace and defense platforms. This opens a new market, though financial impact will take time.
It shows Wolfspeed expanding into aerospace and defense, a new long-term growth avenue.
