Aehr Stock Jumps 17% After Hours: Revenue Triples to a Record $33 Million

Aehr Test Systems (NASDAQ: AEHR) shares jumped about 17% in after-hours trading on Monday, November 2, after the semiconductor test company reported record revenue of $33.0 million — triple a year earlier — and raised its full-year outlook to $150 million. The stock had fallen 6.23% in the regular session to $51.47, then reversed sharply after the close as investors reacted to earnings that beat expectations by a wide margin.

What happened, in one answer

Aehr reported fiscal first-quarter 2027 results for the quarter ended September 25, 2026. Revenue was a record $33.0 million, up 200% from $11.0 million a year earlier and up 75% from the previous quarter. Non-GAAP earnings were $0.28 per share, well above the roughly $0.10 to $0.11 analysts had expected, on revenue that also beat a consensus of about $26.8 million to $27.5 million. Management then raised fiscal 2027 revenue guidance to $150 million, the top of its previous $130 million to $150 million range.

Key facts

• Revenue: $33.0 million, a record, up 200% year over year and 75% sequentially.
• Earnings: Non-GAAP EPS of $0.28 and GAAP net income of $7.2 million; non-GAAP net income was $9.4 million.
• Bookings: $46.7 million in the quarter, more than 40% above revenue — a book-to-bill ratio of about 1.4.
• Backlog: Effective backlog reached $109.3 million as of November 1, including orders booked after the quarter ended.
• Guidance: Fiscal 2027 revenue now expected at $150 million, with non-GAAP net income of at least 20% of revenue. That target is roughly triple fiscal 2026 revenue of about $50 million.
• Stock move: Down 6.23% to $51.47 in regular trading, then up about 16.6% to 17% after hours to around $60.

Why it is blowing up

Aehr makes test and burn-in equipment — systems that run semiconductor devices under heat and power to catch early failures before they ship. That unglamorous step has become valuable in the AI buildout, because expensive AI processors for hyperscale data centers cannot be allowed to fail in the field. The company said demand for its wafer-level and package-level burn-in solutions drove the quarter, and its chief executive, Gayn Erickson, pointed to bookings running well ahead of sales as evidence that demand is still building.

The math behind the guidance also caught attention. Add the $33.0 million already reported to the $109.3 million effective backlog and the total is $142.3 million — close to the entire $150 million full-year target, with three quarters still to run. That does not guarantee every order ships this fiscal year, but it explains why a guidance raise to the top of the range was read as confidence rather than hope.

The reversal in the shares added to the drama. Aehr had been sold off during Monday's session, in a market where the S&P 500 fell 0.51% and the Nasdaq fell 1.07% ahead of Apple and Palantir earnings. The after-hours earnings release flipped the day's story in minutes, making AEHR one of the largest after-hours gainers on November 2 alongside names such as Backblaze and Harmonic.

What to watch next

Two tests now matter. First, execution: Aehr needs about $117 million of revenue over the next three quarters to reach $150 million, and management has warned that quarterly shipments can vary and that second-quarter gross margin is expected to be lower than the first quarter's because of heavy Sonoma system deliveries. Second, cash: operating cash flow was negative in the quarter as the company bought long-lead components and invested in capacity, and its cash balance fell by about $11 million since the end of May — profit has not yet turned into cash.

Investors will also watch a planned installation in early 2027, when a major AI processor supplier is expected to install a fully configured FOX wafer-level burn-in cell at a Taiwan OSAT, with a high-volume production decision expected several months after validation. A production order there could become one of Aehr's largest deals. This report describes what happened and why markets reacted; it is not a recommendation to buy, sell or hold any security.
