Aehr Test Systems Lands $22M AI Processor Order as Jefferies Issues Buy Rating

Aehr Test Systems Secures Major AI Processor Order

Aehr Test Systems announced a $22 million follow-on production order from its lead wafer-level AI processor customer, a provider of advanced AI training and inference processors1

1

. The order encompasses multiple fully automated FOX-XP wafer-level burn-in systems, FOX WaferPak full-wafer contactors, and integrated FOX WaferPak Auto Aligners, with each FOX-XP system configured to test and burn in nine 300mm wafers simultaneously2

2

. The systems will ship over the next six months for installation at the customer's high-volume manufacturing partner in Taiwan4

Stock Surge Reflects Growing Market Confidence

Shares of Aehr Test Systems surged 11.8% following the order announcement, pushing the stock to a new 52-week high of $133.35 intraday2

2

. The rally extends a remarkable run that has seen the stock climb over 550% in the past year, though currently trading at $123.30 with a market cap of $4.02 billion1

1

. The broader semiconductor equipment sector provided support, with peers Teradyne and Cohu also trading higher, though the magnitude of Aehr's move reflects company-specific catalysts rather than sector-wide momentum2

Jefferies Initiates Coverage with Bullish Outlook

Jefferies initiated coverage on Aehr Test Systems with a buy rating and a price target of $175.00, viewing the company as the only vendor offering both wafer- and package-level burn-in qualified into AI production1

1

. The firm forecasts a 52% fiscal year 2025 through fiscal year 2028 revenue compound annual growth rate and expects gross margin to recover to 45% by fiscal year 20281

1

. Jefferies noted the market still prices the company against its legacy silicon carbide profile, despite the dramatic business transformation underway.

Dramatic Business Transformation Toward AI

Aehr Test Systems has undergone a striking pivot from more than 90% silicon carbide revenue in fiscal year 2024 to AI representing more than 90% in fiscal year 20261

1

. This transformation positions the company at the intersection of critical AI infrastructure trends, including advanced packaging, silicon photonics, and reliability testing for increasingly complex semiconductor devices1

1

. Gayn Erickson, President and Chief Executive Officer, stated that growing interest is driven by the increasing value and complexity of advanced AI semiconductor packages, where early-life failure screening before final assembly delivers quality and economic benefits4

Record Performance and Expanding Pipeline

Fiscal Q4 2026 results showed a swing to profitability with earnings of $0.11 per share against expectations for a small loss, on revenue of approximately $18.8 million—up 33% year over year2

2

. Record bookings of $60.7 million pushed the effective backlog above $100 million, providing unusual revenue visibility2

2

. Management's fiscal 2027 revenue guidance of $130-$150 million far exceeded prior Wall Street estimates, resetting market expectations for the company's growth trajectory2

2

. Analysts anticipate sales growth in the current year with revenue growth forecast at 163% for fiscal 20271

Expanding Market Opportunity in AI-Driven Semiconductor Testing

Erickson noted that the customer's current production plans contemplate capacity beyond this order and that the company continues to engage with additional semiconductor companies and hyperscalers following positive wafer-level benchmark results4

4

. Rising chip value, higher power envelopes, chiplet and high-bandwidth memory integration, and compounding package-yield risk all increase reliability-test intensity1

1

. These trends require earlier known-good-die screening, higher-power thermal stress, and both wafer- and package-level burn-in, directly benefiting Aehr's platforms1

1

. The company believes these trends are expanding the market opportunity for wafer-level burn-in across AI accelerators, CPUs, network processors, and other high-performance computing and semiconductor memory devices4
