Aehr Test Systemsentered fiscal 2027 with a record backlog and raised revenue guidance to$130 million to $150 million, implying roughly160% to 200% year-over-year growth. Management also expects non-GAAP pretax net income to reach 18% to 22% of revenue.
Demand was driven by AI processors, silicon photonics, and data center infrastructure, with fiscal Q4 bookings jumping to$60.7 millionfrom $11.1 million a year ago and backlog rising to a record$80.6 million. The company said AI and silicon photonics burn-in made up more than 80% of Q4 revenue.
The business has diversified away from electric-vehicle silicon carbide: nearly 95% of fiscal 2026 revenue came from non-EV SiC markets, while AI and data center customers became the biggest growth engines. Aehr also highlighted expanding opportunities in wafer-level and package-level burn-in, plus capacity additions to support future demand.
Aehr Test Systems (NASDAQ:AEHR) said it entered fiscal 2027 with record backlog and expects revenue to more than double, citing accelerating demand tied to artificial intelligence processors, silicon photonics and data center infrastructure.
<pre><code> President and Chief Executive Officer Gayn Erickson said the company's fiscal fourth quarter "exceeded consensus street expectations" and capped a year in which Aehr broadened its business beyond its earlier concentration in silicon carbide devices for electric vehicles. → 3 Space Stocks That Could Outshine SpaceX After Its IPO "Just two years ago, over 95% of our business was tied to silicon carbide for electric vehicles, whereas today, almost 95% of our fiscal year 2026 revenue came from markets not electric vehicle silicon carbide," Erickson said. The company issued fiscal 2027 revenue guidance of $130 million to $150 million, which Chief Financial Officer Chris Siu said would represent year-over-year growth of about 160% to 200%. Aehr also expects non-GAAP pretax net income to be 18% to 22% of total revenue. ## AI and Data Center Demand Drive Outlook → The SK Hynix IPO and 2027's AI Memory Squeeze Aehr reported fiscal fourth-quarter bookings of $60.7 million, up more than 500% from $11.1 million in the prior-year quarter. Year-end backlog reached a record $80.6 million, compared with $15.2 million at the end of fiscal 2025. Siu said the company received an additional $20 million in bookings after year-end during a transition period and the first two weeks of fiscal 2027, bringing "effective backlog" to approximately $100.6 million before minimal shipments in that period. Management attributed the bookings increase primarily to purchase orders for Sonoma package-level and FOX wafer-level burn-in systems, WaferPaks and burn-in module boards for AI and silicon photonics processor burn-in. Those gains were partially offset by lower customer orders for silicon carbide WaferPaks. → Meta Platforms Stock Rises as Muse Spark 1.1 AI Model Debuts Erickson said reliability and production wafer-level burn-in and screening for AI accelerators, CPUs and network processors were Aehr's fastest-growing markets in fiscal 2026, representing about 71% of annual revenue. Optical device test and burn-in for data center infrastructure transceivers, chip-to-chip I/O and hard disk drives accounted for another 20%. In the fourth quarter, AI processors and silicon photonics burn-in accounted for more than 80% of revenue, compared with 56% in the prior-year period. Siu said Aehr had three customers representing more than 10% of total quarterly revenue: two targeting the AI market and one focused on data center optical transceivers. ## Fourth-Quarter Revenue Rises; Full-Year Revenue Declines Fourth-quarter revenue totaled $18.8 million, up 34% from $14.1 million in the same quarter a year earlier. Siu said the increase was primarily driven by strong demand from AI and data center customers for FOX systems, Zero Auto Aligners and WaferPaks. Non-GAAP gross margin in the fourth quarter was 45%, up from 35% a year earlier, which Siu attributed to higher revenue levels, improved manufacturing capacity utilization and a more favorable product mix. Non-GAAP operating expenses rose to $7.5 million from $5.4 million, reflecting higher employment costs, additional headcount for research and development projects, higher commissions tied to record bookings and ongoing legal fees related to patent litigation against SemiE in China. Non-GAAP net income for the quarter was $3.6 million, or $0.11 per diluted share, compared with a non-GAAP net loss of $0.2 million, or $0.01 per diluted share, in the fourth quarter of fiscal 2025. For the full year, Aehr reported revenue of $50 million, down 15% from fiscal 2025. Full-year non-GAAP gross margin was 38.5%, compared with 44% a year earlier. Non-GAAP net income was $0.9 million, or $0.03 per diluted share, compared with $4.6 million, or $0.15 per diluted share, in fiscal 2025. Cash, cash equivalents and restricted cash totaled $116.5 million at the end of the fourth quarter. Siu said Aehr raised approximately $100 million during fiscal 2026, primarily through its at-the-market program, while capital expenditures were $2.1 million. ## Wafer-Level and Package-Level Platforms Expand Erickson said Aehr's lead AI processor wafer-level burn-in customer doubled its systems from the company over the past year and moved "all production burn and screening to wafer-level burn-in" on Aehr systems. He said that customer is forecasting significant increases in wafer allocation from its foundry this year and beyond. Aehr also said it completed benchmark testing of its wafer-level burn-in solution with a major supplier of AI accelerators, CPUs and network processors. Erickson said the results exceeded the customer's expectations and were described by the customer as "better than they can get at package level." The customer has expressed interest in moving to pilot production test validation at its semiconductor contract manufacturer in Taiwan for a current high-volume device, and has requested evaluation of a second device in parallel. On the package-level side, Erickson highlighted record follow-on production orders from Aehr's lead hyperscale customer for Sonoma systems used in high-volume AI processor production burn-in. He said the customer is forecasting a substantial expansion of Sonoma purchases for a second device that has twice the power per package as the first device now using Sonoma systems. ## Silicon Photonics, Power Semiconductors and Memory Opportunities Erickson said demand for silicon photonics burn-in is gaining momentum as AI data center architectures rely more heavily on optical I/O and high-speed optical interconnects. Aehr's lead silicon photonics customer has placed follow-on orders, while another major silicon photonics customer, described as a global leader in networking products and solutions, has provided a forecast for additional systems this calendar year. In power semiconductors, Aehr said it completed more than a dozen gallium nitride WaferPak designs now being sampled by potential customers, and completed what Erickson described as the world's first 300-millimeter GaN wafer-level burn-in solution. The company also sold its first FOX system for a silicon MOSFET wafer-level burn-in application and secured its first silicon carbide customer in Taiwan. Aehr announced about $8 million in new silicon carbide WaferPak orders in the past month, including expanded orders from its lead silicon carbide customer and an order directly from one of the largest automotive companies in the world for qualification of silicon carbide devices for new electric vehicles. On memory, Erickson said Aehr continues to pursue NAND flash and potential high-bandwidth flash and DRAM applications. However, during the question-and-answer session, he said the company does not currently anticipate memory revenue in its fiscal 2027 guidance, adding that any memory-related upside would be incremental. ## Capacity Buildout Underway Siu said Aehr continues to scale manufacturing capacity, including its Fremont expansion and the start of Sonoma system shipments from an existing contract manufacturer in Southeast Asia. He said that arrangement adds capacity for more than 20 additional Sonoma systems per month. Erickson said Aehr does not believe it is capacity-limited at the $150 million revenue level and is working to maintain flexibility without building excessive fixed infrastructure. In response to analyst questions, he said the company is preparing for larger customer opportunities while acknowledging that execution remains complex due to supply chain and component considerations. "With multiple customers entering or expanding production, a record backlog, and additional opportunities under discussion for both wafer level and package level burn-in, we believe Aehr is well-positioned for multiple years of strong revenue growth," Erickson said. ## About Aehr Test Systems (NASDAQ:AEHR) Aehr Test Systems develops, manufactures and sells semiconductor test and burn-in equipment used by device manufacturers to ensure quality and reliability of integrated circuits.

"Aehr has successfully de-risked its business by replacing cyclical EV SiC revenue with secular AI/silicon-photonics tailwinds that should drive multiple years of >50% revenue CAGR at expanding margins."
AEHR's pivot from EV SiC (now <5% of FY26 revenue) to AI processors, silicon photonics, and data-center burn-in is real: Q4 bookings surged 447% to $60.7M, backlog hit a record $80.6M ($100.6M effective), and FY27 guidance implies 160-200% revenue growth to $130-150M at 18-22% pretax margins. Wafer-level adoption by a lead AI customer and Sonoma package-level expansions from hyperscalers look durable. However, FY26 revenue still fell 15% to $50M, gross margins compressed to 38.5%, and legal/patent costs rose. The $116.5M cash balance (bolstered by $100M ATM) provides a buffer, but execution risk on supply-chain scaling for >20 Sonoma systems/month is non-trivial.
The entire 160-200% growth narrative rests on a handful of hyperscale AI customers whose own capex could be cut if GPU demand softens or if they vertical-integrate test; memory upside is explicitly excluded from guidance, and any slippage in the complex supply chain for high-power Sonoma systems could turn the $150M ceiling into a ceiling in reality.
"Aehr's pivot to AI is technically impressive, but the company's extreme customer concentration and reliance on unproven pilot production cycles make the 200% growth target a binary outcome rather than a baseline."
Aehr Test Systems is attempting a high-stakes pivot from volatile EV silicon carbide to the AI/data center infrastructure gold rush. The 160-200% revenue growth guidance for fiscal 2027 is aggressive, and the shift to 80% AI-related revenue in Q4 suggests they have successfully captured critical design wins in burn-in testing. However, the company's fiscal 2026 full-year revenue decline of 15% reveals a fragile transition period. While the $100.6 million 'effective backlog' provides visibility, the heavy reliance on a few key customers—three of which constitute over 30% of revenue—creates significant concentration risk. Investors should watch the conversion rate of these pilot programs to mass production, as hardware cycles in AI are notoriously prone to sudden shifts in technical standards.
The massive revenue guidance relies heavily on unproven pilot programs in Taiwan and a few hyperscale customers who could easily delay or cancel orders if their own AI chip demand hits a cyclical wall.
"AEHR's 160-200% growth guidance is credible given $100.6M effective backlog and 80%+ AI/photonics revenue mix, but execution hinges on three hyperscale customers maintaining capex intensity and the company avoiding supply-chain disruptions that could compress the 45% gross margins now driving profitability."
AEHR's 160-200% FY27 guidance rests on an $80.6M backlog converting at high margins (18-22% pretax), but the article obscures critical execution risk. Full-year FY26 revenue fell 15% YoY to $50M despite record Q4 bookings—suggesting either lumpy project cycles or prior-year demand cliff. The company claims it's not capacity-constrained at $150M, yet is simultaneously scaling Fremont and outsourcing Sonoma production. Three customers represent >10% of Q4 revenue: concentration risk if any major AI/datacenter customer delays capex or shifts to competitors like Xcerra or LTX-Credence. Memory upside is explicitly excluded from guidance, removing optionality.
If AI capex spending moderates in 2027 or customers internalize burn-in capability, backlog converts at 60-70% rates rather than the ~90%+ implied by guidance. SemiE patent litigation in China could disrupt supply or force costly settlements.
"The aggressive FY2027 guidance is unlikely to be achieved given the current base, concentration risk, and potential margin and execution headwinds from capacity expansion."
Aehr's Q4/2026 results show a pivot from EV SiC to AI/data-center burn-in with record backlog and a 130-150m revenue guide for FY2027. While the backlog and 60.7m quarterly bookings sound loud, the base is tiny: 50m annual revenue in 2026, so 130-150m implies 2.6x top-line growth, which is aggressive for a niche equipment maker with high fixed costs. Risks: concentration on a few large customers, potential order deferrals, supply-chain and capacity ramp constraints, and ongoing patent/legal costs. Margin guidance (18-22% pretax) may be challenged by ramp costs and product mix shifts as capacity expands. With macro AI spend uncertain, the bullish thesis hinges on a sustained AI cycle.
The key bullish counterpoint is that AI/data-center burn-in demand can be durable and the company has visible backlog; if capacity ramps smoothly and customers deploy larger systems, the growth could surprise to the upside. However, even then, the magnitude of the stated FY2027 target remains questionable given the current base and mix.
"Supply-chain pinch for high-power burn-in subsystems is the unmentioned execution chokepoint that could cap FY27 well below the $150M ceiling."
Claude and Gemini both flag customer concentration and pilot-to-production risk, but none of you noted that Sonoma's >20 systems/month ramp requires specialized high-power thermal management components already in tight supply across the AI supply chain. A single hyperscaler delay cascades faster here than in standard ATE because AEHR's effective backlog already prices in near-100% conversion.
"The aggressive revenue growth targets are undermined by significant equity dilution, which will severely compress EPS upside even if operational execution succeeds."
Grok's focus on thermal management supply constraints is critical, yet everyone is ignoring the balance sheet impact of the $100M ATM offering. Dilution is the silent killer here; even if the 160-200% revenue growth materializes, EPS accretion will be significantly muted by the increased share count. We are looking at a company attempting to buy its way into a capex-heavy pivot while simultaneously diluting shareholders to fund the very inventory they might not be able to source.
"ATM dilution is secondary to execution risk on supply-chain bottlenecks that could crater backlog conversion rates below guidance assumptions."
Gemini's ATM dilution concern is real, but the math matters. $100M raised at ~$25/share adds ~4M shares (15% dilution). If FY27 hits $140M midpoint at 20% pretax margins ($28M net), that's $0.70/share pretax—still accretive even post-dilution if AEHR avoids secondary offerings. The actual risk: if backlog converts at 70% instead of 90%, dilution becomes destructive. Grok's thermal supply constraint is the real binding constraint here, not balance sheet mechanics.
"The real risk is scaling Sonoma—reliability and ramp yields could cause the FY27 target to miss even at 70% backlog conversion."
Claude's 70% backlog-conversion scenario helps avoid a cherry-picked 90% assumption, but it doesn't solve the scaling risk. The real concern is Sonoma's reliability and yield at >20 systems per month, plus the high-power thermal/power-module supply squeeze. If field failures, warranty costs, or slower-than-anticipated design-win-to-production ramp appear, even a 70% conversion rate may miss the FY27 target and erode margins, despite the upfront backlog.
Aehr Test Systems' FY27 guidance of 160-200% revenue growth is aggressive and hinges on successful conversion of a record backlog, primarily from AI and data-center burn-in testing. However, the company faces significant risks, including customer concentration, supply chain constraints, and potential dilution from a recent ATM offering.
Successful conversion of the record backlog and expansion of AI and data-center burn-in testing could drive substantial revenue growth.
