Demand for AI Processor Testing Drives Aehr Test Systems’ Record Order Backlog and Share Revaluation

Shares of Aehr Test Systems (NASDAQ: AEHR) have risen 256.7% over the past six months, propelled by a series of record bookings, major new orders and a growing backlog that has given investors greater visibility into future revenue. The shift in demand from electric vehicle power semiconductors to high-volume AI processor and silicon photonics testing has fundamentally changed the company’s outlook, with management issuing robust guidance and analysts revising price targets upward in response to accelerating adoption across multiple semiconductor segments.

Major Orders and Shift to AI-Centric Demand

The principal catalyst for Aehr’s share revaluation has been a series of large-scale orders from AI processor and silicon photonics customers. In April, the company secured a $41 million production order from a hyperscale AI customer for Sonoma package-level burn-in systems. In August, Aehr announced a $22 million follow-on order from a lead wafer-level AI processor customer for FOX-XP systems and WaferPak contactors in Taiwan. These wins have driven bookings for Q4 2026 to $60.7 million, up more than 500% year-over-year, and pushed the effective backlog to over $100 million.

Management guidance for fiscal 2027 points to revenue in the range of $130–$150 million, representing a 160%–200% year-over-year increase. Approximately 77% of this guidance is already covered by backlog, providing unusually high visibility for a company in the semiconductor equipment sector. The shift in Aehr’s revenue mix has been pronounced: the business has transitioned from being over 90% reliant on SiC for EVs in fiscal 2024 to over 90% AI-driven in fiscal 2026, with silicon photonics and power semiconductors comprising the remainder.

Financial Evidence and Order Momentum

Fiscal Q4 2026 revenue rose 33.7% year-over-year to $18.8 million, with non-GAAP net income of $3.6 million ($0.11/share), well ahead of consensus expectations. Full-year revenue for fiscal 2026 totaled $50 million (down from $59 million in fiscal 2025), but the fourth quarter marked a swing back to profitability and a sharp improvement in gross margin, which rose to 45% from 35% a year earlier. The company’s cash position increased to $116.5 million following a $100 million ATM raise and a $97.4 million public offering.

Record backlog and bookings have provided a foundation for robust guidance. Management expects FY2027 non-GAAP net income margins of 18%–22%. Analyst consensus, led by Jefferies’ initiation with a “Buy” rating and a price target of $175, projects a 52% revenue CAGR through fiscal 2028, reflecting confidence in continued demand from AI and silicon photonics customers.

Industry Tailwinds and Broader Context

The surge in global demand for AI processors, generative AI infrastructure, and advanced power semiconductors has provided a strong macro tailwind for Aehr’s test and burn-in solutions. Silicon carbide and gallium nitride devices remain critical for EVs and industrial power electronics, but the AI and silicon photonics segments are expanding the company’s addressable market and reducing reliance on automotive demand. The wafer-level burn-in and reliability testing market is forecasted to reach $4.51 billion by 2030, with Aehr accounting for an estimated 35% share of global wafer-level burn-in systems in 2023.

Geopolitical and supply chain factors have also shaped the sector. US-China tensions, export controls and tariffs have raised manufacturing and freight costs but have not materially disrupted Aehr’s order flow. Positive economic data from China and accelerating international EV and industrial demand are contributing to recovery in SiC orders outside the US.

Product Innovation, Strategic Partnerships and Competitive Position

Aehr’s proprietary FOX-XP and FOX-NP systems, combined with WaferPak and DiePak carriers, enable high-throughput, parallel testing and burn-in that deliver cost advantages and a strong technology moat compared to competitors such as Teradyne, Cohu, FormFactor and Advantest. The company’s partnership with ISE/ASE, the world’s largest OSAT, aims to co-market wafer-level burn-in for AI processors, further broadening its reach. The acquisition of Incal Technology has expanded Aehr’s addressable market within AI semiconductors and enabled the launch of new ultra-high-power, fully automated Sonoma systems for next-generation AI and silicon photonics applications.

Recurring revenue from consumables now makes up more than half of sales, supporting margin stability and scalability. The company’s participation in major industry conferences and investor events throughout 2026 has enhanced visibility and institutional engagement.

Aehr Test Systems’ performance over the past six months has been defined by accelerating AI-driven demand, record orders and a fundamental shift in its business mix. The company’s robust guidance and expanding backlog have reinforced investor confidence, but the sustainability of execution, customer diversification and margin expansion will remain central to the investment narrative as the semiconductor cycle evolves.
