Aehr Test Systems: Revenue Miss, EPS Beat, but Strong Backlog Signals Future Growth

Aehr Test Systems reported revenue of $10.3 million for Q3 FY2026, missing the street estimate of $10.8 million by 5.0%. The company's non-GAAP EPS of -$0.05, however, beat the street estimate of -$0.07 by 28.6%. According to CFO Chris Siu, "Q3 revenue was slightly below consensus and down 44% from $18.3 million in the prior year period." This revenue decline is attributed to delayed orders, which impacted the quarter's performance.

Despite the revenue miss, Aehr Test Systems' backlog and bookings provide a strong foundation for future growth. The company reported a significant increase in bookings, with $37.2 million in the third quarter, up from $6.2 million in the second quarter. This surge in bookings is a direct result of multiple purchase orders for FOX systems, WaferPaks, and auto aligners from various customers in AI, silicon photonics, and silicon carbide applications.

CEO Gayn Erickson highlighted the company's strong momentum: "We're very pleased with the strong momentum in our business across multiple market segments highlighted by more than $37 million in quarterly bookings and a book-to-bill ratio exceeding 3.5x." The company's effective backlog, which includes the quarter-end backlog of $38.7 million plus additional bookings received since the end of the quarter, has grown to a record $50.9 million. This provides strong visibility for the remainder of fiscal 2026 and positions the company for significant growth in fiscal 2027.

Aehr Test Systems' non-GAAP gross margin for Q3 FY2026 was 36.5%, down from 42.7% in the same period last year. This decline is primarily due to the lower revenue and the mix of products sold. Despite the margin compression, the company maintained flat non-GAAP operating expenses at $6.3 million, consistent with the prior year.

Aehr Test Systems ended the quarter with a strong cash position, with $37.1 million in cash, cash equivalents, and restricted cash, up from $31 million at the end of Q2. The company has been active in capital raising, securing $10.5 million in gross proceeds through the sale of about 269,000 shares during the third quarter. Since the end of Q3, the company has raised an additional $19.5 million in gross proceeds through the sale of about 477,000 shares. CFO Chris Siu summarized the capital raising efforts: "And with the $9.9 million we raised in Q2, we have now fully utilized $40 million available under the ATM and have sold over 1.13 million shares at an average price of $35.38."

For the full fiscal year 2026, Aehr Test Systems expects revenue to be on the high side of the $45 million to $50 million range, with a non-GAAP net loss per diluted share between negative $0.13 and negative $0.09. CEO Gayn Erickson reiterated the company's guidance: "We currently expect full year fiscal '26 revenue to be on the high side of the $45 million to $50 million range provided last quarter." The company also expects bookings for the second half of the fiscal year to be on the high side of the $60 million to $80 million range provided last quarter.

Aehr Test Systems' strong bookings and backlog have positive implications for its key customers, particularly STMicroelectronics [STM] and Infineon [IFX.DE]. The company's focus on wafer-level burn-in and test systems for AI, silicon photonics, and silicon carbide applications aligns with the growing demand for advanced semiconductor solutions. The significant increase in bookings suggests that these customers are ramping up their production capabilities, which should benefit Aehr Test Systems in the long term.

Aehr Test Systems operates in a highly competitive market, and a comparison with its peers provides context for its performance. Among its peers in the Test_Assembly subsector, Aehr Test Systems' revenue of $10.3 million and gross margin of 36.5% are significantly lower than those of larger players like Advantest [ATEYY] and Daiichi Seiko [DSCSY]. However, the company's focus on niche markets and its strong backlog position it for future growth.

Advantest, for example, reported revenue of ¥334.1 billion and a gross margin of 67.4%, with a revenue YoY growth of 43.8%. Daiichi Seiko reported revenue of ¥135.5 billion and a gross margin of 70.8%, with a revenue YoY growth of 12.3%. While these figures are much higher than Aehr Test Systems', the company's strong bookings and backlog suggest that it is well-positioned to capture growth opportunities in its target markets.

Aehr Test Systems' Q3 FY2026 earnings report reflects a mixed performance, with a revenue miss and an EPS beat. The company's strong backlog and significant bookings, however, provide a positive outlook for the remainder of the fiscal year and beyond. The company's focus on advanced semiconductor solutions and its strong financial position, coupled with a transparent and optimistic earnings call, position Aehr Test Systems for future growth in the highly competitive semiconductor equipment market.
