Aehr Test Systems Beats Estimates, Signals Strong FY2027 with Record Backlog

Aehr Test Systems reported Q4 FY2026 revenue of $18.8 million, a 0.6% beat over the street estimate of $18.7 million. This marks a significant improvement from the prior year's $14.1 million, representing a 33.7% year-over-year growth. The company's non-GAAP EPS of $0.11 was a notable swing from the expected loss of $0.01, driven by strong operational performance and improved gross margins.

The company's gross margin for the quarter was 42.6%, up 1,000 basis points from 35% in the same period last year, per CFO Chris Siu: "Non-GAAP gross margin for the fourth quarter was 45% up 1 thousand basis points compared with 35% in the same period last year." This improvement in margins is a positive sign, indicating better cost control and higher-margin product mix.

Operating expenses for the quarter were $7.5 million, up from $5.4 million in the prior year. Despite the increase in expenses, the company managed to report a non-GAAP net income of $3.6 million, or $0.11 per diluted share, compared to a non-GAAP net loss of $200 thousand, or negative $0.01 per diluted share, in the fourth quarter of fiscal 25, as stated by Chris Siu: "Non-GAAP net income for the fourth quarter, excluding the impact of stock based compensation and amortization of intangible assets, was $3.6 million or $0.11 per diluted share."

Aehr Test Systems reported a record backlog of $80.6 million at the end of Q4 FY2026, up from $15.2 million at the end of fiscal 25. Subsequent to year-end, the company received an additional $20 million in bookings during the 4-week transition period and the first 2 weeks of fiscal 27, bringing the effective backlog to approximately $100.6 million, as noted by Chris Siu: "As a result, our effective backlog increased to approximately $100.6 million before taking into account minimal shipments during the transition period ended June 26, 2026."

Bookings in the fourth quarter were $60.7 million, up more than 500% from $11.1 million in the prior year quarter. This significant increase in bookings is a strong indicator of future revenue growth and customer demand.

This guidance is significantly higher than the company's FY2026 revenue of $50 million, down 15% year over year.

This level of profitability, combined with the strong backlog, suggests that Aehr Test Systems is well-positioned to capitalize on the growing demand for its products.

Aehr Test Systems' strong performance is driven by demand from key markets, including AI and data center optical transceivers. In the fourth quarter, the company had three customers representing more than 10% of total revenue, with two targeting the AI market and the third focusing on the data center optical transceiver market, as stated by Chris Siu: "For the fourth quarter, we had 3 customers representing more than 10% of total revenue. 2 of these customers target the AI market and the third focuses on the data center optical transceiver market."

Aehr Test Systems' financial position remains strong, with cash, cash equivalents, and restricted cash totaling $116.5 million at the end of the fourth quarter, compared with $26.The company's capital-light model, with only $2.

The guidance tone, however, decreased slightly to 0.29 from 0.41, indicating a more cautious approach to future expectations. The prepared sentiment score dropped significantly to 0.02 from 0.45, while the QA sentiment improved to 0.30 from 0.06, as shown in the tone history.

The company's AI optimism score decreased to 0.36 from 0.51, and uncertainty increased to 40.7 from 35.5. The QA evasiveness score also increased significantly to 41.0 from -24.8, suggesting a more defensive stance in answering questions.

Compared to its peers in the Test and Assembly subsector, Aehr Test Systems' gross margin of 42.6% is in line with the industry average, but its revenue growth of 33.7% year-over-year is significantly higher than most peers. For example, Advantest Corporation (ATEYY) reported a gross margin of 67.4% and revenue growth of 43.8% year-over-year, while Shibaura Mechatronics Corporation (6315.T) reported a gross margin of 36.2% and revenue growth of 22.6% year-over-year.

Aehr Test Systems' Q4 FY2026 results and forward guidance indicate a strong turnaround and a promising outlook for FY2027. The company's record backlog, strong bookings, and improved financial metrics suggest that it is well-positioned to capitalize on the growing demand for its products in key markets. The company's financial position and capital-light model provide the flexibility to scale production and meet customer demand, while the positive tone and sentiment on the earnings call further support the company's optimistic outlook.
