Aehr Test Systems Stock Soars on Earnings, Eyes Over 150% Revenue Growth

Aehr Test Systems shares jumped nearly 22% after the company beat earnings estimates and issued strong fiscal 2027 revenue guidance of $130 million to $150 million.

This small stock has risen about 320% in 2026, and sits at a market capitalization of $2.7 billion in mid-July. Though shares have been in a downtrend over the past 30 days, they saw a huge rebound after Aehr posted its latest earnings report, spiking nearly 22% in a single day.

Aehr’s large move came as it surpassed estimates during the quarter and issued inspiring guidance. This guidance meaningfully changes how investors should view Aehr’s valuation and increases confidence in its outlook.

Aehr’s Revenue Rises Over 30%, Gross Margin Explodes Upward Aehr makes machines that put semiconductors under intense conditions, testing them for defects. As data center operators look to increase performance by weeding out faulty chips, Aehr has been gaining considerable order momentum. In Q4 of its fiscal year 2026 (FY2026), Aehr posted revenue of $18.84 million. (Note that Aehr’s fiscal reporting period is several quarters ahead of the calendar year period.)

Despite Aehr’s impressive quarter, full FY2026 revenue declined 15% YOY to $50 million. Aehr’s business has been transitioning from an overwhelming focus on EV markets to one overwhelmingly focused on non-EV markets, including AI.

This guidance crystallizes Aehr’s success in generating orders for its Sonoma and FOX-XP systems. Over the past few quarters, Aehr has repeatedly announced significant orders within the AI chip industry. This has led to the company making strong statements about bookings, such as that second-half FY2026 bookings would come in “at the high end of its $60 million to $80 million range.” A record $41 million hyperscaler order allowed it to surpass that estimate. Aehr’s huge revenue guidance figure provides a clean metric that shows how far the company has come. Another figure that underpins this confidence is Aehr’s effective backlog of $100.6 million. The company simply has to deliver these booked orders to realize the revenue, absent ...
