Q3 FY2026 Financial Results — Revenue, GAAP and Non-GAAP Net Loss, Cash
Aehr Test Systems, Inc. (NASDAQ: AEHR) reported its third quarter fiscal 2026 financial results on April 7, 2026. The company posted net revenue of $10.3 million for Q3 FY2026, representing a sharp 43.7% year-over-year decline compared to $18.3 million in Q3 FY2025. The revenue contraction was attributed primarily to delayed orders and lower shipments of FOX wafer-level burn-in (WLBI) systems and WaferPak contactors, partially offset by increased demand for Sonoma package-level burn-in (PLBI) systems and burn-in modules (BIMs) from hyperscale customers. (Aehr Test Systems IR, April 2026).
On a GAAP basis, the company reported a net loss of $3.2 million for Q3 FY2026, or $0.10 per diluted share, compared to a GAAP net loss of $0.6 million, or $0.02 per diluted share, in Q3 FY2025. Non-GAAP results for Q3 FY2026, which exclude stock-based compensation and acquisition-related adjustments, showed a net loss of $1.5 million, or $0.05 per diluted share, versus non-GAAP net income of $2.0 million, or $0.07 per diluted share last year.
Cash, cash equivalents, and restricted cash stood at $37.1 million at the end of Q3 FY2026, up from $31.0 million at the end of Q2 FY2026. For the first nine months of FY2026, Aehr reported net revenue of $31.2 million, down from $44.9 million in the comparable period of FY2025, a GAAP net loss of $8.5 million, or $0.28 per diluted share, and a non-GAAP net loss of $2.6 million, or $0.09 per diluted share. Cash used in operating activities for the nine-month period totaled $5.1 million.
Record Bookings and AI Processor Demand
Despite the revenue decline in Q3 FY2026, Aehr achieved a record in quarterly bookings, signaling a robust recovery in demand driven by AI and data center infrastructure investments. Bookings for Q3 FY2026 totaled $37.2 million, a more than fivefold increase from the prior quarter and a substantial acceleration from the previous year. This resulted in a book-to-bill ratio exceeding 3.5x, calculated as $37.2 million in bookings divided by $10.3 million in recognized revenue for Q3 FY2026. The ratio underscores that new orders are outpacing fulfilled shipments by a wide margin, a key indicator of strengthening demand and future revenue visibility.
Aehr’s CEO, Gayn Erickson, highlighted several major wins with leading AI processor customers. The company secured a significant follow-on production order for multiple new FOX-XP wafer-level burn-in systems from its lead AI processor customer. These systems are designed for production screening of advanced AI processors used in hyperscale data center training and inference workloads. The FOX-XP’s ability to deliver high current per wafer enables parallel burn-in of large numbers of high-power devices, a critical requirement as AI workloads and processor power densities rise.
Erickson noted that the company is engaged with multiple additional AI processor companies on benchmarking and qualification programs, reflecting the broader industry shift toward wafer-level burn-in for reliability screening of next-generation AI accelerators. While some benchmark programs have experienced technical delays, customer feedback remains positive, and Aehr expects these engagements to convert to production orders as technical hurdles are resolved.
Silicon Photonics Expansion and New Customer Wins
Aehr’s momentum extends into the rapidly growing silicon photonics segment, which is increasingly critical for high-speed, energy-efficient optical interconnects in hyperscale data centers. In Q3 FY2026, Aehr announced a major new customer win in silicon photonics, securing an initial order for multiple high-power FOX-XP wafer-level burn-in systems. These systems will be deployed for engineering qualification and high-volume production of silicon photonics devices targeting the data center optical interconnect market.
The company also received a follow-on order from its lead silicon photonics customer for an additional FOX-XP WaferPak system and an upgrade to the latest fully automated configuration. Notably, Aehr’s systems have been integrated with the customer’s autonomous guided robots, enabling fully lights-out, hands-free operation in high-throughput manufacturing environments.
The silicon photonics market itself is undergoing rapid expansion, with industry forecasts projecting a compound annual growth rate (CAGR) of over 25% through 2035, driven by the proliferation of AI/ML workloads, cloud infrastructure build-outs, and the transition to optical interconnects for data center and high-performance computing (HPC) applications (GMI Insights, Dec 2025). Aehr’s recent customer wins and product shipments position the company to capture a growing share of this market, particularly as large-scale data center operators and hyperscalers accelerate adoption of silicon photonics-based solutions.
Backlog, Outlook, and FY2026 Second Half
Aehr exited Q3 FY2026 with a reported backlog of $38.7 million, reflecting the cumulative value of unfulfilled customer orders as of February 27, 2026. In the first five weeks of Q4 FY2026, the company secured an additional $12.2 million in bookings, lifting its “effective backlog” (quarter-end backlog plus subsequent bookings) to a record $50.9 million. This backlog provides substantial visibility into future revenue streams and underpins management’s confidence in a demand recovery.
For the second half of FY2026, ending May 29, 2026, Aehr reiterated that it expects bookings to reach the high end of its previously stated $60 million to $80 million range. This guidance reflects ongoing strength in both wafer-level and package-level burn-in demand, particularly from AI processor and silicon photonics customers. The company anticipates a significant near-term follow-on production order from its lead hyperscale customer, which is expected to drive a ramp in shipments of Sonoma package-level burn-in systems beginning in the second half of calendar 2026 and continuing into FY2027.
The production ramp for Sonoma systems is tied to the customer’s next-generation, higher-power AI accelerators, which require advanced burn-in and reliability screening due to increased power densities and integration complexity. Aehr’s management highlighted that the customer is forecasting a substantial expansion of Sonoma purchases, reinforcing the company’s outlook for sustained growth in the coming fiscal year.
The combination of a record effective backlog, strong bookings momentum, and a visible pipeline of production orders from leading AI and silicon photonics customers positions Aehr for a return to non-GAAP profitability in Q4 FY2026 and sets the stage for top-line growth in FY2027. Management also noted that liquidity has improved, with the company completing its $40 million at-the-market (ATM) equity program and ending Q3 FY2026 with $37.1 million in cash, providing flexibility to support ongoing investments in R&D and customer programs.
