Wolfspeed's AI Growth Stalls as Earnings Miss, Shares Plunge

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.

Wolfspeed's AI Hype Meets a Brutal Earnings Reality Check

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.

Wolfspeed's SiC wins AI data center, robot, aerospace demand

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.

AXT Soars on AI InP Demand, Record Prices, Big Capital Raise

AI-driven indium phosphide demand Q2 revenue jumped 160% to $47.6M, gross margin hit 44.9%, and backlog exceeded $100M as AI data centers drove demand for indium phosphide used in high-speed optical connections.
This is the core fundamental driver of the stock's surge this period.
Record price hikes and supply deals Record InP price increases above 10% lifted shares, while supply deals with Casela, Coherent, and Lumentum—including prepayments through 2031—locked in revenue and reduced export and payment risks.
Pricing power and long-term contracts directly boosted investor confidence and revenue visibility.
Massive capital raise for capacity expansion AXT raised $632M, ending with $748.8M cash to double InP capacity in 2026 and expand again in 2027, positioning for co-packaged optics from late 2027.
The capital raise funds growth and signals confidence in future demand.
Competition and uncertain future revenue Rising competition from Coherent and Lumentum remains a risk, and future co-packaged optics revenue is still uncertain and years away.
This is the main counterweight to the positive drivers.

AXT's AI-Driven InP Boom: Record Results, Price Hikes, Supply Deals

Blowout Q2 Earnings AXT reported Q2 revenue up 160% to $47.6 million and gross margin expanding to 44.9% from 8%, driven by record indium phosphide sales for AI data centers. This profit surge directly boosts investor confidence and the stock price.
It's the core fundamental catalyst that kicked off the period's rally.
Record InP Price Hikes A report of Q4 indium phosphide substrate price increases exceeding 10%—the largest on record—sent AXT shares up 13.7% in a day. Higher prices mean more revenue and profit per wafer, directly lifting AXT's earnings potential.
It's a new pricing catalyst that directly boosts AXT's core product economics.
Expanded Supply Agreements AXT signed long-term InP supply deals with Casela, Coherent, and Lumentum, including prepayments and commitments through 2031. With demand already exceeding capacity, these contracts lock in future revenue and improve visibility, supporting the stock.
It shows concrete customer commitments that de-risk future growth.
Strong Liquidity for Expansion AXT ended Q2 with $748.8 million in cash after a $632 million offering, funding a doubling of InP capacity in 2026 and another expansion in 2027. This financial strength lets AXT meet soaring AI demand, but rising competition from Coherent and Lumentum is a risk.
It explains how AXT can scale to capture demand, while noting a real counterweight.

AXT's AI-Driven Indium Phosphide Demand Surges with New Supply Deals

Record Indium Phosphide Revenue and Backlog AXT expects record second-quarter Indium Phosphide revenue, driven by AI data center demand. The company has already secured about $34 million in Q2 revenue and has a backlog exceeding $100 million, the highest ever. This strong demand pushes the stock up as investors see accelerating growth.
This point directly explains the surge in demand for AXT's core product, a key driver of the stock's recent rise.
New Supply Agreements Reduce Risk and Lock in Revenue AXT signed a $25.4 million supply deal with China's Casela for 2027 and a three-year agreement with Coherent, including a $22.3 million prepayment. These deals limit export and payment risks and provide revenue visibility, boosting investor confidence and the stock price.
These agreements are new, material contracts that de-risk future revenue and support the bullish case for AXTI.
Expansion into Co-Packaged Optics for Future Growth AXT is positioning for co-packaged optics, a next-generation AI data center technology, with commercial opportunities expected from late 2027. This potential new revenue stream, alongside capacity expansion, gives investors a longer-term growth narrative that supports the stock.
This highlights a new growth avenue that could drive future demand, relevant to the big picture of why AXTI is moving.
Analyst Upgrade and Board Appointment Northland reiterated an Outperform rating and raised its price target to $125, citing a positive conference appearance. AXT also appointed a new board member with strong financial experience. These developments reinforce positive sentiment and support the stock's upward momentum.
Analyst actions and governance improvements can influence investor perception and are part of the current positive narrative.
